Which of the following is not involved in managing chronic pain caused by cancer?
Your Answer: Pinaverium
Explanation:Medications for Pain Relief in Various Conditions
Pinaverium is a medication that is commonly used to reduce the duration of pain in individuals with irritable bowel syndrome (IBS). On the other hand, carbamazepine is used to treat neuropathic pain that is associated with malignancy, diabetes, and other disorders. Clodronate is another medication that is used to treat malignant bone pain and hypercalcaemia by inhibiting osteoclastic bone resorption.
Corticosteroids are also used to treat pain caused by central nervous system tumours. These medications work by reducing inflammation and oedema, which in turn relieves the pain caused by neural compression. Nifedipine is another medication that is used to relieve painful oesophageal spasm and tenesmus that is associated with gastrointestinal tumours.
Lastly, oxybutynin is a medication that is used to relieve painful bladder spasm. Overall, these medications are used to treat pain in various conditions and can provide relief to individuals who are experiencing discomfort.

What is the combination of ingredients in Hartmann's solution?
Your Answer: Sodium, chloride and potassium
Correct Answer: Sodium, chloride, potassium, calcium and lactate
Explanation:Hartmann’s Solution Composition and Metabolism
Hartmann’s solution, also known as lactated Ringer’s solution, is an intravenous fluid that is isotonic in nature. It contains various compounds, including sodium, chloride, potassium, calcium, and lactate. A litre of this solution contains 131 mmol of sodium, 111 mmol of chloride, 5 mmol of potassium, 2 mmol of calcium, and 29 mmol of lactate.
One of the unique features of Hartmann’s solution is the presence of lactate, which is metabolized by the liver to release bicarbonate. This process is important because bicarbonate would otherwise combine with calcium to form calcium carbonate, which can cause complications. Therefore, the metabolism of lactate helps to maintain the stability of the solution and prevent any adverse effects.

A 55-year-old man comes to the doctor complaining of double vision. Upon examination, his eye is turned down and out, and he has limited adduction, elevation, and depression of the eye, as well as ptosis. Additionally, his pupil is fixed and dilated. What is the probable diagnosis?
Your Answer: Fourth nerve palsy
Correct Answer: Third nerve palsy
Explanation:Common Cranial Nerve Palsies and Their Symptoms
Cranial nerve palsies can cause a variety of symptoms depending on which nerve is affected. Here are some common cranial nerve palsies and their associated symptoms:
Third Nerve Palsy: This affects the oculomotor nerve and causes the eye to be positioned downward and outward, along with ptosis (drooping eyelid) and mydriasis (dilated pupil).
Sixth Nerve Palsy: This affects the abducens nerve and causes medial deviation of the eye.
Fourth Nerve Palsy: This affects the trochlear nerve and causes the eye to look out and down, resulting in vertical or oblique diplopia (double vision). Patients may tilt their head away from the affected side to correct this.
Horner’s Syndrome: This presents with miosis (constricted pupil), ptosis, and ipsilateral anhidrosis (lack of sweating on one side of the face).
Fifth Nerve Palsy: This affects the trigeminal nerve, which is responsible for facial sensation and some motor functions related to biting and chewing. It does not affect the eye.

A 65-year-old man comes to the clinic complaining of lethargy. He denies any other systemic symptoms. During the physical examination, a non-pulsatile mass is palpated in the right lower quadrant of his abdomen, which does not move with respiration. Additionally, he has pale conjunctivae. What is the best course of action for management?
Your Answer: Urgent referral to local colorectal service
Explanation:The presence of an abdominal mass along with symptoms of lethargy and pallor may indicate the likelihood of colorectal cancer, which could also lead to anaemia.
Referral Guidelines for Colorectal Cancer
Colorectal cancer is a serious condition that requires prompt diagnosis and treatment. In 2015, the National Institute for Health and Care Excellence (NICE) updated their referral guidelines for patients suspected of having colorectal cancer. According to these guidelines, patients who are 40 years or older with unexplained weight loss and abdominal pain, 50 years or older with unexplained rectal bleeding, or 60 years or older with iron deficiency anemia or change in bowel habit should be referred urgently to colorectal services for investigation. Additionally, patients who test positive for occult blood in their feces should also be referred urgently.
An urgent referral should also be considered for patients who have a rectal or abdominal mass, unexplained anal mass or anal ulceration, or are under 50 years old with rectal bleeding and any of the following unexplained symptoms/findings: abdominal pain, change in bowel habit, weight loss, or iron deficiency anemia.
The NHS offers a national screening program for colorectal cancer, which involves sending eligible patients aged 60 to 74 years in England and 50 to 74 years in Scotland FIT tests through the post. FIT is a type of fecal occult blood test that uses antibodies to detect and quantify the amount of human blood in a single stool sample. Patients with abnormal results are offered a colonoscopy.
The FIT test is also recommended for patients with new symptoms who do not meet the 2-week criteria listed above. For example, patients who are 50 years or older with unexplained abdominal pain or weight loss, under 60 years old with changes in their bowel habit or iron deficiency anemia, or 60 years or older who have anemia even in the absence of iron deficiency. Early detection and treatment of colorectal cancer can significantly improve patient outcomes, making it important to follow these referral guidelines.

A 13-year-old boy comes to the clinic with swelling at the lower end of his right femur. Upon examination, a calcified, nodular shadow is observed in his lung on a chest x-ray. What is the most probable diagnosis?
Your Answer: Osteosarcoma
Explanation:Osteogenic Sarcoma: A Common Bone Cancer in Children and Adolescents
Osteogenic sarcoma is a prevalent type of bone cancer that primarily affects children and adolescents. It is the third most common malignancy in this age group. The tumour usually originates in the metaphyseal regions of the distal femur, proximal tibia, and proximal humerus, but it can develop in any bone. The cancer can spread regionally within the same extremity or systemically to other organs, such as the lung. Unfortunately, the prognosis worsens dramatically when the tumour metastasises. A common radiological finding in such cases is chest nodules or cannonball lesions.

A 16-year-old woman presents with primary amenorrhoea. She is of normal height and build and has normal intellect. Her breast development is normal, and pubic hair is of Tanner stage II. Past history revealed an inguinal mass on the right side, which was excised 2 years ago. Ultrasonography of the lower abdomen reveals no uterus.
Which of the following tests will help in diagnosis of the condition?Your Answer: Serum oestradiol level
Correct Answer: Karyotype
Explanation:Diagnosis of Androgen Insensitivity Syndrome: A Case Study
The presented case strongly suggests the presence of androgen insensitivity syndrome, a condition where a patient’s phenotype and secondary sexual characteristics differ from their karyotype and gonads. In this case, the patient is likely to have a karyotype of 46,XY and be a male pseudohermaphrodite. Androgen insensitivity syndrome is associated with mutations in the AR gene, which codes for the androgen receptor. In complete androgen insensitivity, the body cannot respond to androgens at all, resulting in a female phenotype, female secondary sexual characteristics, no uterus, and undescended testes.
Karyotyping is the key diagnostic investigation to confirm the diagnosis of androgen insensitivity syndrome. Serum oestradiol levels may vary according to the type of androgen insensitivity disorder and are unlikely to aid the diagnosis. Pituitary MRI may be a second diagnostic investigation if karyotype abnormalities are ruled out. Transvaginal ultrasound is not necessary if an abdominal ultrasound has already been performed and showed an absent uterus.

An 80-year-old woman complains of colicky abdominal pain and a tender mass in her groin. Upon examination, a small firm mass is found below and lateral to the pubic tubercle. What is the most probable underlying diagnosis?
Your Answer: Incarcerated obturator hernia
Correct Answer: Incarcerated femoral hernia
Explanation:The most probable cause of the symptoms, which include intestinal issues and a mass in the femoral canal area, is a femoral hernia. This type of hernia is less common than inguinal hernias but accounts for a significant proportion of all groin hernias.
Understanding the Femoral Canal
The femoral canal is a fascial tunnel located at the medial aspect of the femoral sheath. It contains both the femoral artery and femoral vein, with the canal lying medial to the vein. The borders of the femoral canal include the femoral vein laterally, the lacunar ligament medially, the inguinal ligament anteriorly, and the pectineal ligament posteriorly.
The femoral canal is significant as it allows the femoral vein to expand, enabling increased venous return to the lower limbs. However, it can also be a site for femoral hernias, which occur when abdominal contents protrude through the femoral canal. This is a potential space, and the relatively tight neck of the canal places hernias at high risk of strangulation.
The contents of the femoral canal include lymphatic vessels and Cloquet’s lymph node. Understanding the anatomy and physiological significance of the femoral canal is important for medical professionals in diagnosing and treating potential hernias and other conditions that may affect this area.

A 70-year-old man with dementia is assessed and found to lack capacity. As per the Mental Capacity Act 2005, decisions will need to be made on his behalf by a Court-Appointed Deputy in his best interests.
Your Answer: Decisions relating to her treatment of a mental disorder
Correct Answer: Decisions relating to her welfare
Explanation:Exclusions from the Mental Capacity Act: Decisions Not Covered by the Act
The Mental Capacity Act allows for decisions to be made in the best interests of a person who lacks capacity. However, there are certain decisions that are not covered by the Act.
Decisions relating to a person’s welfare can be made in their best interests, but personal decisions such as consenting to marriage or civil partnership are excluded from the Act. Similarly, decisions regarding consent for making an adoption order or placing a child for adoption are not covered.
The Act also does not give consent for medical treatment of a mental disorder, which falls under the jurisdiction of the Mental Health Act. Additionally, the Act does not permit anyone to vote on behalf of a person who lacks capacity in an election or referendum.
It is important to note these exclusions when considering decision-making for individuals who lack capacity.

A 60-year-old man visits his GP complaining of hand pain that worsens with activity and towards the end of the day. He has a medical history of psoriasis and is not currently taking any medications. During the examination, the doctor notes tender bony swellings in three DIP joints on both hands. What is the probable diagnosis?
Your Answer: Osteoarthritis
Explanation:The presence of Heberden’s nodes, which are bony swellings at the DIP joints, is a characteristic feature of osteoarthritis in the hand. Pain that worsens with activity, rather than rest, is also more indicative of OA than inflammatory arthritis. Psoriatic arthritis can cause swelling of the DIP joints, but the swelling is typically boggy rather than bony, and the pain tends to be worse in the morning and improve with activity. Reactive arthritis is unlikely to cause a DIP predominant arthritis, as it typically presents as a large joint lower limb oligoarthritis, and there is no recent history of infection. Rheumatoid arthritis does not typically affect the DIP joints.
Understanding Osteoarthritis of the Hand
Osteoarthritis of the hand, also known as nodal arthritis, is a condition that occurs when the cartilage at synovial joints is lost, leading to the degeneration of underlying bone. It is more common in women, usually presenting after the age of 55, and may have a genetic component. Risk factors include previous joint trauma, obesity, hypermobility, and certain occupations. Interestingly, osteoporosis may actually reduce the risk of developing hand OA.
Symptoms of hand OA include episodic joint pain, stiffness that worsens after periods of inactivity, and the development of painless bony swellings known as Heberden’s and Bouchard’s nodes. These nodes are the result of osteophyte formation and are typically found at the distal and proximal interphalangeal joints, respectively. In severe cases, there may be reduced grip strength and deformity of the carpometacarpal joint of the thumb, resulting in fixed adduction.
Diagnosis is typically made through X-ray, which may show signs of osteophyte formation and joint space narrowing before symptoms develop. While hand OA may not significantly impact a patient’s daily function, it is important to manage symptoms through pain relief and joint protection strategies. Additionally, the presence of hand OA may increase the risk of future hip and knee OA, particularly for hip OA.

A 5-year-old girl is brought to the emergency department with difficulty breathing. Since yesterday, she has developed a fever (38.5ºC) and become progressively short of breath. On examination, she appears unwell with stridor and drooling. Her past medical history is otherwise unremarkable.
What is the most probable causative organism for this presentation?Your Answer: Haemophilus influenzae B
Explanation:Acute epiglottitis is a rare but serious infection caused by Haemophilus influenzae B (HiB) bacteria. It is characterized by a sudden onset of fever, stridor, and drooling due to inflammation of the epiglottis. It is important to keep the affected child calm and seek specialist input from anaesthetics and paediatrics. In the UK, the current vaccination against HiB has made epiglottitis uncommon. Bordetella pertussis, Streptococcus pneumoniae, and Parainfluenza virus are incorrect answers as they do not produce the same presentation as acute epiglottitis.
Acute epiglottitis is a rare but serious infection caused by Haemophilus influenzae type B. It is important to recognize and treat it promptly as it can lead to airway obstruction. Although it was once considered a disease of childhood, it is now more common in adults in the UK due to the immunization program. The incidence of epiglottitis has decreased since the introduction of the Hib vaccine. Symptoms include a rapid onset, high temperature, stridor, drooling of saliva, and a tripod position where the patient leans forward and extends their neck to breathe easier. Diagnosis is made by direct visualization, but x-rays may be done to rule out a foreign body.
Immediate senior involvement is necessary, including those who can provide emergency airway support such as anaesthetics or ENT. Endotracheal intubation may be necessary to protect the airway. It is important not to examine the throat if epiglottitis is suspected due to the risk of acute airway obstruction. The diagnosis is made by direct visualization, but only senior staff who are able to intubate if necessary should perform this. Treatment includes oxygen and intravenous antibiotics.

You are asked to see an elderly patient who has not opened their bowels for several days. Their abdomen is distended, and they describe cramping abdominal pain that comes and goes. A supine abdominal X-ray is performed to identify features of bowel obstruction and suggest the location of the obstruction.
Which of the following is more characteristic of the large bowel, rather than the small bowel, on an abdominal X-ray?Your Answer: Haustral folds
Explanation:Characteristics of Small and Large Bowel Anatomy
The human digestive system is composed of various organs that work together to break down food and absorb nutrients. Two important parts of this system are the small and large bowel. Here are some characteristics that differentiate these two structures:
Haustral Folds and Valvulae Conniventes
Haustral folds are thick, widely separated folds that are characteristic of the large bowel. In contrast, valvulae conniventes are thin mucosal folds that pass across the full width of the small bowel.Location
The small bowel is located towards the center of the abdomen, while the large bowel is more peripheral and frames the small bowel.Diameter
The normal maximum diameter of the small bowel is 3 cm, while the large bowel can have a diameter of up to 6 cm. The caecum, a part of the large bowel, can have a diameter of up to 9 cm.Air-Fluid Levels in Obstruction
The appearance of air-fluid levels is characteristic of small bowel obstruction.Remembering the 3/6/9 Rule
To help remember the normal diameters of the small and large bowel, use the 3/6/9 rule: the small bowel has a diameter of 3 cm, the large bowel can have a diameter of up to 6 cm, and the caecum can have a diameter of up to 9 cm.Understanding the Differences Between Small and Large Bowel Anatomy

A 65-year-old man presents to clinic with a three month history of worsening lower urinary tract symptoms and nocturnal enuresis. Upon examination, he has a painless distended bladder and a smoothly enlarged prostate on digital rectal examination. Bladder scan reveals 1.5L residual and ultrasound kidney, ureter, bladder (US KUB) shows bilateral hydronephrosis. His blood results are as follows:
Na+ 136 mmol/L (135 - 145)
K+ 4.5 mmol/L (3.5 - 5.0)
Bicarbonate 28 mmol/L (22 - 29)
Urea 6.5 mmol/L (2.0 - 7.0)
Creatinine 310 µmol/L (55 - 120)
What is the most likely diagnosis?Your Answer: Chronic high pressure urinary retention
Explanation:Chronic urinary retention is considered high pressure if it leads to impaired renal function or hydronephrosis. A painless distended bladder containing over 1 L of urine is a common symptom of chronic urinary retention, usually caused by bladder outflow obstruction. In this case, the patient’s elevated creatinine levels (290) and bilateral hydronephrosis visible on US KUB indicate high pressure chronic retention. Low pressure chronic urinary retention, on the other hand, does not cause hydronephrosis or renal impairment. Acute urinary retention typically presents with supra-pubic tenderness and a palpable bladder, but does not usually result in a painless distended bladder. Catheterisation typically drains less than 1 L of urine. Given the patient’s painless distended bladder and 1.2L urine volume, acute urinary retention is unlikely.
Understanding Chronic Urinary Retention
Chronic urinary retention is a condition that develops gradually and is usually painless. It can be classified into two types: high pressure retention and low pressure retention. High pressure retention is often caused by bladder outflow obstruction and can lead to impaired renal function and bilateral hydronephrosis. On the other hand, low pressure retention does not affect renal function and does not cause hydronephrosis.
When chronic urinary retention is diagnosed, catheterisation may be necessary to relieve the pressure in the bladder. However, this can lead to decompression haematuria, which is a common side effect. This occurs due to the rapid decrease in pressure in the bladder and usually does not require further treatment.

A 48-year-old patient has requested a consultation to discuss the outcome of her recent cervical screening test. The test showed normal cytology and was negative for high-risk human papillomavirus (hrHPV). In her previous screening test 18 months ago, she had normal cytology but tested positive for hrHPV. What guidance should you provide to the patient based on her latest screening test result?
Your Answer: Return to routine recall in 5 years time
Correct Answer: Return to routine recall in 3 years time
Explanation:If the result of the first repeat smear for cervical cancer screening at 12 months is negative for high-risk human papillomavirus (hrHPV), the patient can resume routine recall. This means they should undergo screening every 3 years from age 25-49 years or every 5 years from age 50-64 years. However, if the repeat test is positive again, the patient should undergo another HPV test in 12 months. If there is dyskaryosis on a cytology sample, the patient should be referred for colposcopy.
The cervical cancer screening program has evolved to include HPV testing, which allows for further risk stratification. A negative hrHPV result means a return to normal recall, while a positive result requires cytological examination. Abnormal cytology results lead to colposcopy, while normal cytology results require a repeat test at 12 months. Inadequate samples require a repeat within 3 months, and two consecutive inadequate samples lead to colposcopy. Treatment for CIN typically involves LLETZ or cryotherapy. Individuals who have been treated for CIN should be invited for a test of cure repeat cervical sample 6 months after treatment.

A 38-year-old teacher and mother of two presents with back pain. This started after lifting some heavy boxes during a move. The pain was initially limited to her lower back but now she has shooting pains radiating down the back of her thigh, the lateral aspect of her leg and into the lateral border of her left foot. The pain can wake her at night if she moves suddenly but does not otherwise disturb her sleep. She is well, without past medical history of note. She reports no lower limb weakness, disturbance of sphincter function, nor any saddle symptoms. Examination reveals a tender lumbar spine, numbness to the lateral border of the left foot and pain on straight leg raise at 40 degrees on the left. There is no limb weakness.
What is the most appropriate management plan?Your Answer: Give analgesia and refer for physiotherapy, with a review after 8 weeks to consider onward referral to a spinal surgeon or musculoskeletal medicine specialist if no better
Explanation:Management of Sciatica: Analgesia and Referral for Physiotherapy
Sciatica, also known as lumbar radiculopathy, is a common condition caused by a herniated disc, spondylolisthesis, or spinal stenosis. It is characterized by pain, tingling, and numbness that typically extends from the buttocks down to the foot. Diagnosis is made through a positive straight leg raise test. Management involves analgesia and early referral to physiotherapy. Bed rest is not recommended, and patients should continue to stay active. Symptoms usually resolve within 6-8 weeks, but if they persist, referral to a specialist may be necessary for further investigation and management with corticosteroid injections or surgery. Red flag symptoms, such as major motor weakness, urinary/faecal incontinence, saddle anaesthesia, night pain, fever, systemic symptoms, weight loss, past history of cancer, or immunosuppression, require urgent medical attention.

A 28-year-old female arrives at the emergency department with her husband who is worried about her unusual behavior. The patient discloses that her sister passed away in a car accident recently and the funeral was held last week. She expresses her deep love and closeness with her sister and admits to feeling very sad. The psychiatrist confirms this sentiment with the husband. However, while recounting the events of her sister's death and funeral, she begins to smile and laugh, describing the events in a cheerful tone. What is the most appropriate term to describe the patient's abnormal behavior?
Your Answer: Incongruity of affect
Explanation:Common Psychiatric Terms Explained
Psychiatric terms can be difficult to understand, but it’s important to know what they mean. Incongruity of affect is when a patient’s emotional expression does not match the situation they are describing. This can be confusing for both the patient and the clinician. Anhedonia is another term that is commonly used in psychiatry. It refers to the inability to feel pleasure from activities that were once enjoyable. This can be a symptom of depression or other mental health conditions. Depersonalisation and derealisation are two terms that are often used interchangeably, but they have different meanings. Depersonalisation is the feeling that one’s self is not real, while derealisation is the feeling that the world is not real. Finally, thought blocking is when a person suddenly stops their train of thought. This can be a symptom of schizophrenia or other mental health conditions.

A 34-year-old woman is at eight weeks’ gestation in her first pregnancy, with a body mass index (BMI) of 36.5 kg/m2. She has type 2 diabetes mellitus, and her sister had pre-eclampsia in both her pregnancies. She had deep vein thrombosis (DVT), following a long-haul flight to Australia last year. Which of the following risk factors presenting in this patient’s history is considered a high-risk factor for the development of pre-eclampsia?
Your Answer: Family history of a first-degree relative with pre-eclampsia
Correct Answer: Type 2 diabetes mellitus
Explanation:Pre-eclampsia Risk Factors in Pregnancy
During the first prenatal visit, women are screened for their risk of developing pre-eclampsia during pregnancy.
High-risk factors include a personal history of pre-eclampsia, essential hypertension, type 1 or 2 diabetes mellitus, chronic kidney disease, or autoimmune conditions.
Moderate risk factors include a BMI of 35-39.9 kg/m2, family history of pre-eclampsia, age of ≥ 40, first pregnancy, multiple pregnancy, and an interpregnancy interval of > 10 years. If any high or moderate risk factor is present, it is recommended that the woman take 75 mg of aspirin daily from the 12th week of gestation until delivery.
A personal history of DVT is not a risk factor for pre-eclampsia, but it is associated with an increased risk of thrombi during pregnancy and the puerperium.

A 45-year-old man, who is a heavy smoker, was seen in the Surgical Outpatient Clinic, complaining of severe pain in both legs, even at rest. On examination, he had chronic ulceration of his toes.
Which of the following conditions is he most likely to have?Your Answer: Buerger’s disease
Explanation:The patient is suffering from Buerger’s disease, also known as thromboangiitis obliterans. This disease affects medium-sized and small arteries, particularly the tibial and radial arteries, and can extend to veins and nerves of the extremities. It is most commonly seen in heavy cigarette-smoking men, but there has been an increase in cases among women due to changing smoking trends. The disease typically begins before the age of 35 and causes severe pain, even at rest, due to neural involvement. Chronic ulcerations and gangrene can occur as later complications. Abstinence from smoking in the early stages can prevent further attacks. Other possible conditions, such as granulomatosis with polyangiitis, Kawasaki’s disease, polyarteritis nodosa, and Takayasu’s arthritis, have been ruled out based on the patient’s symptoms and medical history.

A 56-year-old man with a medical history of COPD, ulcerative colitis, hypertension, and hypothyroidism presented to your clinic for follow-up. He was recently released from the hospital after being diagnosed with pneumonia. According to the discharge summary, he had an allergic reaction to co-trimoxazole during his hospital stay, resulting in the discontinuation of one of his regular medications. He has been instructed to consult with his GP about this medication. Which medication is most likely to have been discontinued due to the drug allergy?
Your Answer: Sulfasalazine
Explanation:If a patient has a known allergy to a sulfa drug like co-trimoxazole, they should avoid taking sulfasalazine.
Sulfasalazine: A DMARD for Inflammatory Arthritis and Bowel Disease
Sulfasalazine is a type of disease modifying anti-rheumatic drug (DMARD) that is commonly used to manage inflammatory arthritis, particularly rheumatoid arthritis, as well as inflammatory bowel disease. This medication is a prodrug for 5-ASA, which works by reducing neutrophil chemotaxis and suppressing the proliferation of lymphocytes and pro-inflammatory cytokines.
However, caution should be exercised when using sulfasalazine in patients with G6PD deficiency or those who are allergic to aspirin or sulphonamides due to the risk of cross-sensitivity. Adverse effects of sulfasalazine may include oligospermia, Stevens-Johnson syndrome, pneumonitis/lung fibrosis, myelosuppression, Heinz body anaemia, megaloblastic anaemia, and the potential to color tears and stain contact lenses.
Despite these potential side effects, sulfasalazine is considered safe to use during pregnancy and breastfeeding, making it a viable option for women who require treatment for inflammatory arthritis or bowel disease. Overall, sulfasalazine is an effective DMARD that can help manage the symptoms of these conditions and improve patients’ quality of life.

A 25-year-old female patient visits her GP complaining of severe lower abdominal pain that is not relieved by painkillers. She has no significant medical history. During the evaluation, her GP conducts a pregnancy test, which comes back positive. The patient is immediately referred to the hospital, where a transvaginal ultrasound confirms an ectopic pregnancy in the left tube. What is the best course of action for management?
Your Answer: Vaginal misoprostol
Correct Answer: Salpingectomy
Explanation:If a patient has an ectopic pregnancy, the treatment plan will depend on various factors such as the size and location of the pregnancy, the patient’s overall health, and the potential impact on their fertility. If the pregnancy is small and the patient’s health is stable, they may be able to receive medication to dissolve the pregnancy. However, if the pregnancy is larger or causing severe symptoms, surgery may be necessary.
In cases where surgery is required, the surgeon may attempt to preserve the affected fallopian tube if possible. However, if the tube is severely damaged or the patient has other factors that may affect their fertility, such as age or previous fertility issues, the surgeon may opt to remove the tube completely. This decision will also depend on the patient’s desire for future fertility and the likelihood of requiring further treatment with methotrexate or a salpingectomy. If the patient’s contralateral tube is unaffected, complete removal of the affected tube may be the most appropriate course of action.
Ectopic pregnancy is a serious condition that requires prompt investigation and management. Women who are stable are typically investigated and managed in an early pregnancy assessment unit, while those who are unstable should be referred to the emergency department. The investigation of choice for ectopic pregnancy is a transvaginal ultrasound, which will confirm the presence of a positive pregnancy test.
There are three ways to manage ectopic pregnancies: expectant management, medical management, and surgical management. The choice of management will depend on various criteria, such as the size of the ectopic pregnancy, whether it is ruptured or not, and the patient’s symptoms and hCG levels. Expectant management involves closely monitoring the patient over 48 hours, while medical management involves giving the patient methotrexate and requires follow-up. Surgical management can involve salpingectomy or salpingostomy, depending on the patient’s risk factors for infertility.
Salpingectomy is the first-line treatment for women without other risk factors for infertility, while salpingostomy should be considered for women with contralateral tube damage. However, around 1 in 5 women who undergo a salpingostomy require further treatment, such as methotrexate and/or a salpingectomy. It is important to carefully consider the patient’s individual circumstances and make a decision that will provide the best possible outcome.

A 67-year-old woman visits her gynaecologist with complaints of discomfort and a dragging sensation, as well as a feeling of a lump in her genital area. Upon examination, the clinician notes a prolapse of the cervix, uterus, and vaginal wall, along with bleeding and ulceration of the cervix. Based on Pelvic Organ Prolapse Quantification (POPQ) grading, what type of prolapse is indicated by this patient's symptoms and examination results?
Your Answer: Fourth-degree
Explanation:Prolapse refers to the descent of pelvic organs into the vagina, which can be categorized into different degrees. First-degree prolapse involves the descent of the uterus and cervix, but they do not reach the vaginal opening. Second-degree prolapse is when the cervix descends to the level of the introitus. Third-degree prolapse is the protrusion of the cervix and uterus outside of the vagina. Fourth-degree prolapse is the complete prolapse of the cervix, uterus, and vaginal wall, which can cause bleeding due to cervix ulceration. Vault prolapse is the prolapse of the top of the vagina down the vaginal canal, often occurring after a hysterectomy due to weakness of the upper vagina. The causes of urogenital prolapse are multifactorial and can include factors such as childbirth, menopause, chronic cough, obesity, constipation, and suprapubic surgery for urinary continence.

What is the most probable valvular disease?Your Answer: Aortic stenosis
Correct Answer: Mitral stenosis
Explanation:Differentiating Heart Murmurs: Causes and Characteristics
Heart murmurs are abnormal sounds heard during a heartbeat and can indicate underlying heart conditions. Here are some common causes and characteristics of heart murmurs:
Mitral Stenosis: This condition is most commonly caused by rheumatic fever in childhood and is rare in developed countries. Patients with mitral stenosis will have a loud S1 with an associated opening snap. However, if the mitral valve is calcified or there is severe stenosis, the opening snap may be absent and S1 soft.
Mitral Regurgitation and Ventricular Septal Defect: These conditions cause a pan-systolic murmur, which is not the correct option for differentiating heart murmurs.
Aortic Regurgitation: This condition leads to an early diastolic murmur.
Aortic Stenosis: Aortic stenosis causes an ejection systolic murmur.
Ventricular Septal Defect: As discussed, a ventricular septal defect will cause a pan-systolic murmur.
By understanding the causes and characteristics of different heart murmurs, healthcare professionals can better diagnose and treat underlying heart conditions.

A 35-year-old man presents to his primary care physician with a consistent blood pressure reading of >140/90 mmHg. Laboratory tests indicate a serum potassium level of 2.8 mmol/l. Upon reviewing the patient's medical history, it is discovered that an external radiology report had previously noted a small retroperitoneal mass of unknown significance. What would be the anticipated serum renin and aldosterone levels in this case?
Your Answer: Increased renin; decreased aldosterone
Correct Answer: Decreased renin; increased aldosterone
Explanation:Understanding the Relationship between Renin and Aldosterone Levels in Different Conditions
Renin and aldosterone are two important hormones involved in regulating blood pressure and electrolyte balance in the body. The levels of these hormones can vary in different conditions, providing important clues for diagnosis and treatment.
Decreased renin and increased aldosterone levels are typically seen in Conn syndrome, which is caused by a functioning adenoma in the adrenal cortex. This results in overproduction of aldosterone and a negative feedback loop that reduces renin levels.
On the other hand, increased renin and decreased aldosterone levels are characteristic of primary adrenal insufficiency, which can be caused by autoimmune destruction of the adrenal glands or other factors. This leads to a different clinical picture and requires different management.
A rare finding is decreased renin and aldosterone levels, which can occur in pseudohypoaldosteronism and Liddle’s syndrome. These conditions are associated with genetic mutations that affect the regulation of sodium channels in the kidneys.
Increased renin and aldosterone levels are seen in secondary hyperaldosteronism, which can be caused by various conditions such as renal artery stenosis, congestive cardiac failure, nephrotic syndrome, liver cirrhosis, and renin-secreting tumors.
Finally, normal renin levels with increased aldosterone levels suggest a negative feedback effect of aldosterone on renin production. This can occur in various conditions such as primary hyperaldosteronism or other forms of secondary hyperaldosteronism.
In summary, understanding the relationship between renin and aldosterone levels can provide important insights into the underlying pathophysiology of different conditions and guide appropriate management strategies.

Barbara, a 75-year-old recently widowed woman, visits your medical practice with her son, who is concerned about his mother's memory. Over the past few months, she has been forgetting appointments and conversations that they had just a few days ago, requiring frequent reminders to recall recent events. When you speak with Barbara, she mentions that she has lost her appetite and is waking up earlier than usual. She denies experiencing any hallucinations or issues with movement.
After administering a mini mental state exam, Barbara scores 23, and you observe that she is having difficulty focusing on your questions, often responding with I don't know.
What is the most probable diagnosis?Your Answer: Depression
Explanation:Depression and Alzheimer’s can have similar presentations in elderly patients, so it’s important to consider depression as a possible cause. Depression is a common issue among the elderly, and it can cause concentration problems that may be mistaken for memory loss.
There are several key symptoms that suggest depression, including loss of appetite, early morning wakening, poor concentration, and recent loss of a spouse. When conducting a mini mental state examination, patients with depression may respond with I don’t know, while those with Alzheimer’s may try to answer but give incorrect responses.
MMSE scores can help determine the severity of cognitive impairment, with scores of 24-30 indicating no impairment, 18-23 indicating mild impairment, and 0-17 indicating severe impairment.
Differentiating between Depression and Dementia
Depression and dementia are two conditions that can have similar symptoms, making it difficult to distinguish between the two. However, there are certain factors that can suggest a diagnosis of depression over dementia.
One of the key factors is the duration and onset of symptoms. Depression often has a short history and a rapid onset, whereas dementia tends to develop slowly over time. Additionally, biological symptoms such as weight loss and sleep disturbance are more commonly associated with depression than dementia.
Patients with depression may also express concern about their memory, but they are often reluctant to take tests and may be disappointed with the results. In contrast, patients with dementia may not be aware of their memory loss or may not express concern about it.
The mini-mental test score can also be variable in patients with depression, whereas in dementia, there is typically a global memory loss, particularly in recent memory.
In summary, while depression and dementia can have overlapping symptoms, careful consideration of the duration and onset of symptoms, biological symptoms, patient concerns, and cognitive testing can help differentiate between the two conditions.

A 25-year-old man comes to you with a history of back pain that has been getting worse over the past year. The pain and stiffness are more severe in the morning but improve with exercise. During your examination, you notice a flexural rash with poorly defined areas of erythema, dry skin, and lichenification. All observations appear normal. The blood test results show an ESR of 84 mm/hr (normal range: 0-22) and a CRP of 6 mg/L (normal range: 0-10). ANA, RhF, and Anti-CCP tests are all negative. What is the most likely diagnosis?
Your Answer: Psoriatic arthritis
Correct Answer: Ankylosing spondylitis
Explanation:Exercise is typically beneficial for inflammatory back pain, such as that seen in ankylosing spondylitis. The patient’s symptoms, including morning stiffness and improvement with exercise, suggest an inflammatory cause, which is supported by the significantly elevated ESR. While there are several possible diagnoses, including seropositive and seronegative spondyloarthropathies, the most likely explanation is ankylosing spondylitis. Psoriatic arthritis is an incorrect answer, as the patient’s rash is more consistent with dermatitis than psoriasis. Osteoarthritis is also unlikely given the patient’s age and clinical history, while reactive arthritis is less likely due to the duration of symptoms and lack of urethritis or conjunctivitis.
Ankylosing spondylitis is a type of spondyloarthropathy that is associated with HLA-B27. It is more commonly seen in young males, with a sex ratio of 3:1, and typically presents with lower back pain and stiffness that develops gradually. The stiffness is usually worse in the morning and improves with exercise, while pain at night may improve upon getting up. Clinical examination may reveal reduced lateral and forward flexion, as well as reduced chest expansion. Other features associated with ankylosing spondylitis include apical fibrosis, anterior uveitis, aortic regurgitation, Achilles tendonitis, AV node block, amyloidosis, cauda equina syndrome, and peripheral arthritis (more common in females).

As a first-year resident on a surgical rotation, which of the following procedures would necessitate the use of prophylactic antibiotics?
Your Answer: Intravascular catheter insertion (tunnelled)
Correct Answer: Appendicectomy
Explanation:Preventing Surgical Site Infections
Surgical site infections (SSI) are a common complication following surgery, with up to 20% of all healthcare-associated infections being SSIs. These infections occur when there is a breach in tissue surfaces, allowing normal commensals and other pathogens to initiate infection. In many cases, the organisms causing the infection are derived from the patient’s own body. Measures that may increase the risk of SSI include shaving the wound using a razor, using a non-iodine impregnated incise drape, tissue hypoxia, and delayed administration of prophylactic antibiotics in tourniquet surgery.
To prevent SSIs, there are several steps that can be taken before, during, and after surgery. Before surgery, it is recommended to avoid routine removal of body hair and to use electrical clippers with a single-use head if hair needs to be removed. Antibiotic prophylaxis should be considered for certain types of surgery, such as placement of a prosthesis or valve, clean-contaminated surgery, and contaminated surgery. Local formulary should be used, and a single-dose IV antibiotic should be given on anesthesia. If a tourniquet is to be used, prophylactic antibiotics should be given earlier.
During surgery, the skin should be prepared with alcoholic chlorhexidine, which has been shown to have the lowest incidence of SSI. The surgical site should be covered with a dressing, and wound edge protectors do not appear to confer any benefit. Postoperatively, tissue viability advice should be given for the management of surgical wounds healing by secondary intention. The use of diathermy for skin incisions is not advocated in the NICE guidelines, but several randomized controlled trials have demonstrated no increase in the risk of SSI when diathermy is used.

A 5-year-old girl, who has been wetting the bed at night attends surgery today with her grandfather, as her mother is at work. Her grandfather is worried because it was also an issue for her older sister, who is 10-years-old and she is prescribed desmopressin. The girl in front of you is otherwise well and her bowels open regularly. An examination is unremarkable and she has a soft non-tender abdomen.
What recommendations would you make?Your Answer: Reassurance and general advice
Explanation:Reassurance and advice can be provided to manage nocturnal enuresis in children under the age of 5 years.
Nocturnal enuresis, or bedwetting, is when a child involuntarily urinates during the night. Most children achieve continence by the age of 3 or 4, so enuresis is defined as the involuntary discharge of urine in a child aged 5 or older without any underlying medical conditions. Enuresis can be primary, meaning the child has never achieved continence, or secondary, meaning the child has been dry for at least 6 months before.
When managing bedwetting, it’s important to look for any underlying causes or triggers, such as constipation, diabetes mellitus, or recent onset UTIs. General advice includes monitoring fluid intake and encouraging regular toileting patterns, such as emptying the bladder before sleep. Reward systems, like star charts, can also be helpful, but should be given for agreed behavior rather than dry nights.
The first-line treatment for bedwetting is an enuresis alarm, which has a high success rate. These alarms have sensor pads that detect wetness and wake the child up to use the toilet. If short-term control is needed, such as for sleepovers, or if the alarm is ineffective or not acceptable to the family, desmopressin may be prescribed. Overall, managing bedwetting involves identifying any underlying causes and implementing strategies to promote continence.

A 25-year-old man visits his GP with a concern about a painless lump in his scrotum and bilateral breast enlargement. What would be the most suitable initial test for the probable diagnosis?
Your Answer: Testicular ultrasound scan
Explanation:If the cause of this patient’s gynaecomastia was suspected to be hyperprolactinaemia, a pituitary MRI could be considered. Gynaecomastia can also be caused by a prolactinoma, which typically results in galactorrhoea. However, there are no other indications of a prolactinoma.
Understanding Testicular Cancer
Testicular cancer is a type of cancer that commonly affects men between the ages of 20 and 30. Germ-cell tumors are the most common type of testicular cancer, accounting for around 95% of cases. These tumors can be divided into seminomas and non-seminomas, which include embryonal, yolk sac, teratoma, and choriocarcinoma. Other types of testicular cancer include Leydig cell tumors and sarcomas. Risk factors for testicular cancer include infertility, cryptorchidism, family history, Klinefelter’s syndrome, and mumps orchitis.
The most common symptom of testicular cancer is a painless lump, although some men may experience pain. Other symptoms may include hydrocele and gynaecomastia, which occurs due to an increased oestrogen:androgen ratio. Tumor markers such as hCG, AFP, and beta-hCG may be elevated in germ cell tumors. Ultrasound is the first-line diagnostic tool for testicular cancer.
Treatment for testicular cancer depends on the type and stage of the tumor. Orchidectomy, chemotherapy, and radiotherapy may be used. Prognosis for testicular cancer is generally excellent, with a 5-year survival rate of around 95% for seminomas and 85% for teratomas if caught at Stage I. It is important for men to perform regular self-examinations and seek medical attention if they notice any changes or abnormalities in their testicles.

Mrs. Smith has recently been diagnosed with bowel cancer. Which marker would be most effective in monitoring the tumor's progression and response to future treatment?
Your Answer: Occult faecal blood
Correct Answer: CEA
Explanation:Colon cancer treatment response is monitored using CEA.
Although CT scans can reveal malignancy progression, they are not suitable for routine monitoring due to their expense and radiation exposure.
Ovarian cancer is detected using Ca-125 as a tumour marker.
Hepatocellular carcinoma is detected using AFP as a tumour marker.Colorectal cancer is typically diagnosed through CT scans and colonoscopies or CT colonography. Patients with tumors below the peritoneal reflection should also undergo MRI to evaluate their mesorectum. Once staging is complete, a treatment plan is formulated by a dedicated colorectal MDT meeting.
For colon cancer, surgery is the primary treatment option, with resectional surgery being the only cure. The procedure is tailored to the patient and tumor location, with lymphatic chains being resected based on arterial supply. Anastomosis is the preferred method of restoring continuity, but in some cases, an end stoma may be necessary. Chemotherapy is often offered to patients with risk factors for disease recurrence.
Rectal cancer management differs from colon cancer due to the rectum’s anatomical location. Tumors can be surgically resected with either an anterior resection or an abdominoperineal excision of rectum (APER). A meticulous dissection of the mesorectal fat and lymph nodes is integral to the procedure. Neoadjuvant radiotherapy is often offered to patients prior to resectional surgery, and those with obstructing rectal cancer should have a defunctioning loop colostomy.
Segmental resections based on blood supply and lymphatic drainage are the primary operations for cancer. The type of resection and anastomosis depend on the site of cancer. In emergency situations where the bowel has perforated, an end colostomy is often safer. Left-sided resections are more risky, but ileocolic anastomoses are relatively safe even in the emergency setting and do not need to be defunctioned.

A 25-year-old male is brought to the emergency department by his friends who are concerned about his behavior. The patient's friends report that over the past few days the patient has hardly slept or eaten and is talking non-stop about a new business idea that he believes will make him a millionaire. He has also been spending a lot of money on his credit card and started making impulsive purchases. During the interview, the emergency department doctor observes that the patient is speaking rapidly and is difficult to interrupt. Despite the speed of his speech, the words themselves are coherent and follow a logical, albeit unusual, pattern of thought.
What is the most appropriate term to describe the patient's abnormal speech pattern?Your Answer: Pressured speech
Explanation:Mania and Related Speech Patterns
Mania is a mental state characterized by elevated mood, energy, and activity levels. A patient presenting with decreased need for sleep, increased risk-taking behavior, and delusions of grandeur may be exhibiting symptoms of mania. One common speech pattern associated with mania is pressured speech, which is characterized by rapid speech that is difficult to interrupt.
Other speech patterns that may be observed in patients with mania include clanging, echolalia, neologism, and word salad. Clanging refers to the use of rhyming words, while echolalia involves repeating what the examiner says. Neologism refers to the creation of new words, and word salad is a completely disorganized speech that is not understandable.
It is important for healthcare professionals to recognize these speech patterns and other symptoms of mania in order to provide appropriate treatment and support for patients. By the characteristics of mania and related speech patterns, healthcare professionals can help patients manage their symptoms and improve their overall quality of life.

A 70-year-old woman comes to the clinic complaining of fatigue and overall weakness. She denies any other symptoms. Upon examination, the patient has conjunctival pallor and an inflamed, red tongue. Initial blood tests show a macrocytic anemia. Further testing reveals positive antiparietal cell antibodies.
What result is most likely to be found upon further investigation?Your Answer: Low vitamin B12
Explanation:Differential diagnosis of a patient with low vitamin B12 and related symptoms
Pernicious anaemia, coeliac disease, Crohn’s disease, and multiple myeloma are among the possible conditions that may cause low vitamin B12 levels and related symptoms. Pernicious anaemia is an autoimmune disorder that affects the gastric mucosa and impairs the production of intrinsic factor, leading to vitamin B12 deficiency and anaemia. Coeliac disease is a chronic immune-mediated enteropathy that affects the small intestine and causes malabsorption of nutrients, including vitamin B12. Crohn’s disease is a chronic inflammatory bowel disease that can affect any part of the gastrointestinal tract and cause various symptoms, including diarrhoea, abdominal pain, and weight loss. Multiple myeloma is a malignant plasma cell disorder that can cause bone pain, anaemia, and other symptoms, but is less likely to present with low vitamin B12 levels as the primary feature.
The differential diagnosis of these conditions may involve various tests and procedures, such as blood tests for antibodies and vitamin B12 levels, endoscopy with biopsies of the duodenum or colon, and bone marrow examination. The specific findings on these tests can help to distinguish between the different conditions and guide further management. For example, the presence of parietal cell antibodies and intrinsic factor antibodies in the blood may support a diagnosis of pernicious anaemia, while villous atrophy and crypt hyperplasia in the duodenal biopsies may suggest coeliac disease. Transmural inflammation with granuloma formation in the colon biopsies may indicate Crohn’s disease, while plasma cell infiltration in the bone marrow may suggest multiple myeloma.
Overall, the diagnosis of a patient with low vitamin B12 and related symptoms requires a thorough evaluation of the clinical history, physical examination, and laboratory findings, as well as consideration of the possible differential diagnoses.

A 55-year-old man visits his doctor, reporting rectal bleeding and a significant family history of colon cancer. The doctor refers him to a colorectal surgeon who orders a colonoscopy. The results show a cancerous tumor in the sigmoid colon after a biopsy and pathological analysis. What is the colon's venous drainage, and where is colonic cancer likely to spread?
Your Answer: Sigmoid veins to the inferior mesenteric veins
Explanation:Venous Drainage of the Intestines
The intestines are drained by a complex network of veins that ultimately lead to the hepatic portal vein. The sigmoid veins drain into the inferior mesenteric veins, while the superior rectal veins drain into the same. The left colic vein drains into the inferior mesenteric vein, while the middle colic vein drains into the superior mesenteric vein. Finally, the jejunal and ileal veins drain into the middle colic vein. This intricate system of venous drainage is essential for the proper functioning of the digestive system.

A 42-year-old woman complains of fatigue after experiencing flu-like symptoms two weeks ago. Upon examination, she has a smooth, small goiter and a pulse rate of 68 bpm. Her lab results show a Free T4 level of 9.3 pmol/L (normal range: 9.8-23.1) and a TSH level of 49.3 mU/L (normal range: 0.35-5.50). What additional test would you perform to confirm the diagnosis?
Your Answer: TSH receptor antibodies
Correct Answer: Thyroid peroxidase (TPO) antibodies
Explanation:Diagnosis and Management of Primary Hypothyroidism
The patient’s test results indicate a case of primary hypothyroidism, characterized by low levels of thyroxine (T4) and elevated thyroid-stimulating hormone (TSH). The most likely cause of this condition is Hashimoto’s thyroiditis, which is often accompanied by the presence of thyroid peroxidase antibodies. While the patient has a goitre, it appears to be smooth and non-threatening, so a thyroid ultrasound is not necessary. Additionally, a radio-iodine uptake scan is unlikely to show significant uptake and is therefore not recommended. Positive TSH receptor antibodies are typically associated with Graves’ disease, which is not the likely diagnosis in this case. For further information on Hashimoto’s thyroiditis, patients can refer to Patient.info.

A 27-year-old woman with three children and a history of two previous terminations of pregnancy presents with menorrhagia. She is seeking advice on the most suitable contraceptive method for her.
What would be the most appropriate contraceptive agent for this patient?Your Answer: Mirena' intrauterine hormone system
Explanation:Contraception and Treatment for Menorrhagia
When a woman is experiencing problematical menorrhagia and needs contraception, it is recommended to use progesterone-based long-acting reversible contraception over progesterone-only or combined-oral contraceptive pills due to its higher efficacy in preventing pregnancy. While tranexamic acid may help reduce menorrhagia, it is not a contraceptive. Mefenamic acid is more effective in providing analgesia than in treating menorrhagia and is also not a contraceptive.
The most appropriate therapy for this situation would be Mirena, which is expected to provide good contraception while also potentially leading to amenorrhoea in the majority of cases. It is important to consider both contraception and treatment for menorrhagia in order to provide comprehensive care for women experiencing these issues. These recommendations are based on the FSRH guidelines on contraception from July 2019.

A 25-year-old medical student is worried that she might have coeliac disease after learning about it during her gastroenterology rotation. She schedules an appointment with her GP to address her concerns, and the GP orders routine blood tests and coeliac serology as the initial investigation. What is the most frequently linked condition to coeliac disease?
Your Answer: Iron deficiency
Explanation:Coeliac Disease and Common Associated Conditions
Coeliac disease is an autoimmune disorder that causes the small intestine villi to atrophy upon exposure to gliadin, resulting in malabsorption syndrome and steatorrhoea. This condition often leads to deficiencies in iron, other minerals, nutrients, and fat-soluble vitamins. While the incidence of gastrointestinal malignancies is increased in people with coeliac disease, it is a relatively rare occurrence. Dermatitis herpetiformis, an itchy, vesicular rash, is commonly linked to coeliac disease and managed with a gluten-free diet. Osteoporosis is also common due to malabsorption of calcium and vitamin D. Infertility is not commonly associated with coeliac disease, especially in those on a gluten-free diet. However, untreated coeliac disease may have an impact on fertility, but results of studies are inconclusive. The most common associated condition with coeliac disease is iron deficiency anaemia.

A 25-year-old male with severe learning difficulties is brought into the emergency department by his parents after accidentally overdosing on paracetamol. He was found 20 minutes ago to have mistakenly ingested 18 grams of paracetamol after briefly being unsupervised. What is the most appropriate initial management for this patient?
Your Answer: Give activated charcoal and then N-acetylcysteine if indicated by paracetamol levels
Explanation:If a patient has ingested paracetamol within 1 hour and it is not a staggered overdose, activated charcoal should be administered to prevent further absorption of the drug. In this scenario, there is no immediate need for N-acetylcysteine (NAC) as the chronology of the overdose is clear from the collateral history provided by concerned parents. However, NAC may be required later. It is important to administer activated charcoal immediately as there is only a small window of opportunity to prevent further absorption of paracetamol. Gastric lavage is not necessary in cases where activated charcoal is available as it has been shown to be a more effective intervention.
Paracetamol overdose management guidelines were reviewed by the Commission on Human Medicines in 2012. The new guidelines removed the ‘high-risk’ treatment line on the normogram, meaning that all patients are treated the same regardless of their risk factors for hepatotoxicity. However, for situations outside of the normal parameters, it is recommended to consult the National Poisons Information Service/TOXBASE. Patients who present within an hour of overdose may benefit from activated charcoal to reduce drug absorption. Acetylcysteine should be given if the plasma paracetamol concentration is on or above a single treatment line joining points of 100 mg/L at 4 hours and 15 mg/L at 15 hours, regardless of risk factors of hepatotoxicity. Acetylcysteine is now infused over 1 hour to reduce adverse effects. Anaphylactoid reactions to IV acetylcysteine are generally treated by stopping the infusion, then restarting at a slower rate. The King’s College Hospital criteria for liver transplantation in paracetamol liver failure include arterial pH < 7.3, prothrombin time > 100 seconds, creatinine > 300 µmol/l, and grade III or IV encephalopathy.

A 3-year-old boy is brought to see the pediatrician by his father. He was born at 34/40 weeks gestation. His father is worried about cerebral palsy, as he has heard that premature birth can cause developmental problems. The child has been meeting all his developmental milestones, but his father is still concerned. During the examination, the boy shows normal power, tone, and reflexes in all four limbs.
What developmental problem would indicate a diagnosis of cerebral palsy in this 3-year-old boy?Your Answer: Not walking by 18 months old (corrected for prematurity)
Explanation:Developmental Milestones and Red Flags in Children: A Guide for Parents and Caregivers
As children grow and develop, they reach certain milestones that indicate their progress in various areas such as motor skills, social skills, and language development. However, if a child is not meeting these milestones within a certain timeframe, it may be a cause for concern and require further investigation. Here are some red flags to look out for:
– Not walking by 18 months old (corrected for prematurity): This may be a sign of cerebral palsy or other developmental problems including muscular dystrophy. Other areas of development should also be assessed.
– Hand preference at 18 months old: It is abnormal for a child to develop hand dominance before the age of 12 months old. This could be a sign of cerebral palsy or an injury causing an occult fracture or neuropathy.
– Loss of attained developmental milestones: While cerebral palsy is a non-progressive condition, delays in achieving milestones may be a sign of prenatal infections, birth trauma, hypoxic brain injury, or meningitis in the neonatal period.
– Not able to balance on one leg by the age of two years: This may be a sign of cerebral palsy or Duchenne muscular dystrophy.
– Not sitting up by six months old (corrected for prematurity): If a baby is unable to sit unsupported by the age of eight months, corrected for prematurity, further investigations should be done.It is important to remember that every child develops at their own pace, but if you have concerns about your child’s development, it is always best to seek advice from a healthcare professional. Early intervention and support can make a significant difference in a child’s development and future outcomes.

A 28-year-old woman visits her GP seeking the combined oral contraceptive pill. She experiences intense one-sided headaches and reports a tingling sensation that travels up her arm before the headache begins. She smokes 10-20 cigarettes on most weekends and has a BMI of 34 kg/m². Her younger sister has a history of thromboembolic disease. What specific aspect of her medical history is the most significant contraindication for prescribing the combined oral contraceptive?
Your Answer: Migraine with aura
Explanation:The patient’s symptoms indicate that they may be suffering from migraine, specifically migraine with aura. This condition is classified as UKMEC 4, meaning that it poses a significant health risk when taking combined oral contraceptive pills. While visual disturbances are the most common aura symptoms, some patients may experience sensory or motor symptoms such as tingling, weakness, or difficulty speaking. While other factors in the patient’s medical history may also be relevant, migraine with aura is the primary concern when considering contraception options.
The decision to prescribe the combined oral contraceptive pill is now based on the UK Medical Eligibility Criteria (UKMEC), which categorizes potential contraindications and cautions on a four-point scale. UKMEC 1 indicates no restrictions for use, while UKMEC 2 suggests that the benefits outweigh the risks. UKMEC 3 indicates that the disadvantages may outweigh the advantages, and UKMEC 4 represents an unacceptable health risk. Examples of UKMEC 3 conditions include controlled hypertension, a family history of thromboembolic disease in first-degree relatives under 45 years old, and current gallbladder disease. Examples of UKMEC 4 conditions include a history of thromboembolic disease or thrombogenic mutation, breast cancer, and uncontrolled hypertension. Diabetes mellitus diagnosed over 20 years ago is classified as UKMEC 3 or 4 depending on severity. In 2016, Breastfeeding between 6 weeks and 6 months postpartum was changed from UKMEC 3 to UKMEC 2.

A 30-year-old pregnant woman presents with a complaint of dyspnoea that has been worsening with physical activity for the past month. She is currently 16 weeks pregnant and has had normal prenatal testing. Upon examination, her vital signs are stable, and her lungs are clear bilaterally without cardiac murmur. Mild dependent oedema is noted in her lower extremities. What is the probable cause of her dyspnoea?
Your Answer: Reduced functional residual capacity
Correct Answer: Increased minute ventilation
Explanation:Physiological Changes During Pregnancy and Breathlessness: Understanding the Relationship
During pregnancy, a woman’s body undergoes numerous physiological changes that can affect her respiratory system. One of the most significant changes is an increase in tidal volume, which leads to an overall increase in minute ventilation. This increased respiratory workload can result in a feeling of breathlessness, which is experienced by up to 75% of pregnant women, particularly during the first trimester. However, it is important to note that this feeling of breathlessness is typically not indicative of any underlying cardiac or pulmonary issues.
While some degree of dependent leg edema is normal during pregnancy, it is important to understand that other respiratory changes, such as a decrease in residual volume or a reduction in functional residual capacity, do not typically contribute to the feeling of breathlessness. Respiratory rate usually remains unchanged during pregnancy.
Overall, understanding the physiological changes that occur during pregnancy and their impact on the respiratory system can help healthcare providers better manage and address any concerns related to breathlessness in pregnant women.

A 35 year old woman presents with a 4 week history of increasing redness over her right breast. She is not breastfeeding and reports feeling generally well. Although the area is not painful, she is worried as it has not improved. Upon examination, there is significant swelling and erythema, but no discharge, nipple changes, or palpable masses. Vital signs are normal and she has no fever. Blood test results are as follows:
- White blood cell count: 6x10^9/L
- C-reactive protein: 4 mg/L
- CA 15-3 level: 57 Units/ml (normal range <30 Units/ml)
What is the most likely diagnosis?Your Answer: Inflammatory breast cancer
Explanation:This woman is suffering from inflammatory breast cancer (IBC), which is evident from the typical symptoms of progressive erythema and edema in the breast, without any signs of infection such as fever, discharge, or elevated WCC and CRP. Additionally, her CA 15-3 levels are elevated. Mastitis and cellulitis would present with fever or elevated WCC and CRP, while Paget’s disease of the breast involves the nipple from the beginning and spreads to the areola and breast, presenting with an eczema-like rash over the nipple with discharge and/or nipple inversion. A fibroadenoma presents as a firm, mobile lump in an otherwise normal breast. IBC is a rare but rapidly progressive form of breast cancer caused by lymph drainage obstruction, resulting in erythema and edema. It is usually a primary cancer and is treated with neoadjuvant chemotherapy as the first line of treatment, followed by total mastectomy +/- radiotherapy.
Breast Cancer Treatment Options and Prognosis
Breast cancer is more common in older individuals and the most common type is invasive ductal carcinoma, which may arise from ductal carcinoma in situ. Pathological assessment involves evaluating the tumor and lymph nodes, with sentinel lymph node biopsy being a common method to minimize morbidity. Treatment options include wide local excision or mastectomy, with the final cosmetic outcome being a consideration. Reconstruction is also an option, with the type of procedure tailored to the patient’s age and co-morbidities. The Nottingham Prognostic Index can be used to give an indication of survival, with tumor size, lymph node score, and grade score being major prognostic parameters. Other factors such as vascular invasion and receptor status also impact survival. The aim of treatment should be to have a local recurrence rate of 5% or less at 5 years.

A patient with uncontrolled asthma is initiated on montelukast. What is the mechanism of action of this medication?
Your Answer: Leukotriene receptor antagonist
Explanation:The management of asthma in adults has been updated by NICE in 2017, following the 2016 BTS guidelines. One of the significant changes is in ‘step 3’, where patients on a SABA + ICS whose asthma is not well controlled should be offered a leukotriene receptor antagonist instead of a LABA. NICE does not follow the stepwise approach of the previous BTS guidelines, but to make the guidelines easier to follow, we have added our own steps. The steps range from newly-diagnosed asthma to SABA +/- LTRA + one of the following options, including increasing ICS to high-dose, a trial of an additional drug, or seeking advice from a healthcare professional with expertise in asthma. Maintenance and reliever therapy (MART) is a form of combined ICS and LABA treatment that is only available for ICS and LABA combinations in which the LABA has a fast-acting component. It should be noted that NICE does not recommend changing treatment in patients who have well-controlled asthma simply to adhere to the latest guidance. The definitions of what constitutes a low, moderate, or high-dose ICS have also changed, with <= 400 micrograms budesonide or equivalent being a low dose, 400 micrograms - 800 micrograms budesonide or equivalent being a moderate dose, and > 800 micrograms budesonide or equivalent being a high dose for adults.

A 56-year-old woman with advanced multiple sclerosis has been experiencing diarrhoea for the past 3 days. She reports no blood in her stool, no abdominal pain, and no fever. Due to her limited mobility, she is currently receiving nasogastric tube feeding. Her recent blood work shows a hemoglobin level of 117 g/L (normal range for females: 115-160 g/L), platelet count of 349 * 109/L (normal range: 150-400 * 109/L), white blood cell count of 10.2 * 109/L (normal range: 4.0-11.0 * 109/L), sodium level of 146 mmol/L (normal range: 135-145 mmol/L), potassium level of 4.9 mmol/L (normal range: 3.5-5.0 mmol/L), urea level of 7.1 mmol/L (normal range: 2.0-7.0 mmol/L), and creatinine level of 58 µmol/L (normal range: 55-120 µmol/L). Her C-reactive protein level is 2 mg/L (normal range: <5 mg/L). What is the most likely cause of her diarrhoea?
Your Answer: Enteral feeding
Explanation:Enteral feeding is a known cause of diarrhoea, which is likely the case for this patient with advanced multiple sclerosis and a nasogastric tube. Abnormal GI functioning due to disease progression and Clostridium-difficile infection are incorrect answers, as they do not explain the patient’s symptoms. Dehydration is also an incorrect answer, as it is usually a result of diarrhoea rather than the cause.
Enteral feeding is a method of providing nutrition to patients who are malnourished or at risk of malnutrition and have a functional gastrointestinal tract. It involves administering food directly into the stomach through a tube, which can be placed either through the nose (nasogastric tube) or directly into the stomach (gastrostomy tube). The type of tube used depends on the patient’s condition and the presence of upper gastrointestinal dysfunction.
To ensure safe and effective enteral feeding, healthcare professionals must check the placement of the tube using aspiration and pH tests. Gastric feeding is preferred, but if there is upper GI dysfunction, duodenal or jejunal tubes may be used. Patients in intensive care units (ICUs) should receive continuous feeding for 16-24 hours, and a motility agent may be used to aid gastric emptying. If this is ineffective, post-pyloric feeding or parenteral feeding may be considered.
Complications of enteral feeding include diarrhoea, aspiration, hyperglycaemia, and refeeding syndrome. Patients who are identified as malnourished or at risk of malnutrition should be considered for enteral feeding, especially if they have a BMI below 18.5 kg/m2, unintentional weight loss of more than 10% over 3-6 months, or a BMI below 20 kg/m2 and unintentional weight loss of more than 5% over 3-6 months. Surgical patients who are malnourished, have an unsafe swallow or inadequate oral intake, and have a functional GI tract may benefit from preoperative enteral feeding.
It is important to note that PEG tubes should not be removed until at least 2 weeks after insertion, and surgical patients due to have major abdominal surgery should be carefully evaluated before enteral feeding is initiated. Overall, enteral feeding is a valuable tool for providing nutrition to patients who are unable to eat normally, but it must be used with caution and under the guidance of a healthcare professional.

A 32-year-old construction worker presents with intense pain in his right flank. He has no significant medical history. After administering appropriate pain management, he reports that he has never encountered this issue before. He often works outside without access to water and has recently started bodybuilding, resulting in an increase in protein consumption. A scan is scheduled to confirm the diagnosis.
What would be the likely diagnosis?Your Answer: Abdominal ultrasound scan
Correct Answer: Non-contrast CT of abdomen and pelvis
Explanation:The formation of renal stones can be attributed to both dehydration and a high intake of protein. In the case of the patient, his physically demanding outdoor profession suggests that he may not be consuming enough fluids. Additionally, his symptoms of flank pain, which were only relieved by diclofenac, indicate that he may be experiencing extreme discomfort. A spiral non-contrast CT scan is the preferred method of investigation for this condition.
Risk Factors for Renal Stones
Renal stones, also known as kidney stones, can be caused by various risk factors. Dehydration is a common risk factor, as it can lead to concentrated urine and the formation of stones. Other factors include hypercalciuria, hyperparathyroidism, hypercalcaemia, cystinuria, high dietary oxalate, renal tubular acidosis, medullary sponge kidney, polycystic kidney disease, and exposure to beryllium or cadmium.
Urate stones, a type of renal stone, have their own set of risk factors. These include gout and ileostomy, which can result in acidic urine and the precipitation of uric acid. Certain drugs can also contribute to the formation of renal stones. Loop diuretics, steroids, acetazolamide, and theophylline can promote calcium stones, while thiazides can prevent them by increasing distal tubular calcium resorption.
In summary, there are various risk factors for renal stones, including dehydration, certain medical conditions, dietary factors, and exposure to certain substances. It is important to be aware of these risk factors and take steps to prevent the formation of renal stones.

A 28-year-old woman presents to her primary care physician with concerning symptoms that have been occurring on and off for the past few months. She reports experiencing episodes of weakness accompanied by rapid, involuntary movements of her arms. Additionally, she has been experiencing persistent tingling sensations, occasional double vision, electric shocks down her arms and trunk when she flexes her neck, and constipation. Based on these symptoms, what would be the most appropriate initial test to diagnose her condition?
Your Answer: Lumbar puncture
Correct Answer: MRI
Explanation:Diagnosing Multiple Sclerosis: The Importance of MRI
Multiple sclerosis (MS) is a debilitating disease that affects many individuals, particularly women. Symptoms can range from spastic weakness to loss of vision, making it difficult to diagnose. However, the first line investigation for somebody with MS is an MRI of the brain and spinal cord. This is because MRI is much more sensitive for picking up inflammation and demyelination than a CT scan, and it does not involve irradiation. Additionally, lumbar puncture can be used to detect IgG oligoclonal bands, which are not present in the serum. While other tests such as antibody testing and slit-lamp examination of the eyes may be useful, they are not first line investigations. It is important to diagnose MS early to prevent further damage to myelin sheaths and improve quality of life.

A 26-year-old male is brought in after a motorcycle accident. According to the paramedic, the patient has suffered a significant loss of blood due to an open femoral fracture, which has been reduced, and a haemothorax. The patient's blood pressure is 95/74 mmHg, and his heart rate is 128 bpm. Although conscious, the patient appears confused. What is the stage of haemorrhagic shock that this patient is experiencing?
Your Answer: Class I (<15% blood loss)
Correct Answer: Class III (30-40% blood loss)
Explanation:The patient is experiencing Class III haemorrhagic shock, indicated by their tachycardia and hypotension. They are not yet unconscious, ruling out Class IV shock. Class I shock would be fully compensated for, while Class II shock would only cause tachycardia. However, in Class III shock, confusion is also present. Class IV shock is characterized by severe hypotension and loss of consciousness.
Understanding Shock: Aetiology and Management
Shock is a condition that occurs when there is inadequate tissue perfusion. It can be caused by various factors, including sepsis, haemorrhage, neurogenic injury, cardiogenic events, and anaphylaxis. Septic shock is a major concern, with a mortality rate of over 40% in patients with severe sepsis. Haemorrhagic shock is often seen in trauma patients, and the severity is classified based on the amount of blood loss and associated physiological changes. Neurogenic shock occurs following spinal cord injury, leading to decreased peripheral vascular resistance and cardiac output. Cardiogenic shock is commonly caused by ischaemic heart disease or direct myocardial trauma. Anaphylactic shock is a severe hypersensitivity reaction that can be life-threatening.
The management of shock depends on the underlying cause. In septic shock, prompt administration of antibiotics and haemodynamic stabilisation are crucial. In haemorrhagic shock, controlling bleeding and maintaining circulating volume are essential. In neurogenic shock, peripheral vasoconstrictors are used to restore vascular tone. In cardiogenic shock, supportive treatment and surgery may be required. In anaphylactic shock, adrenaline is the most important drug and should be given as soon as possible.
Understanding the aetiology and management of shock is crucial for healthcare professionals to provide timely and appropriate interventions to improve patient outcomes.

A 5-year-old girl with confirmed coeliac disease needs a 1-month prescription for gluten-free staple foods.
What would be the most suitable prescription for gluten-free staple foods?Your Answer: 2 kg bread + 1000g pasta + 2 kg oats = 18 units
Correct Answer: 1 kg bread + 750 g pasta + 1 kg oats = 10 units
Explanation:Determining the Correct Gluten Prescription for a Patient
When prescribing gluten for a patient, it is important to follow the National Prescribing Guidelines to ensure the correct amount is given. For example, a combination of 1 kg bread, 750 g pasta, and 1 kg oats would result in 10 units of gluten, which is the recommended amount for a 3-year-old patient. However, it is important to note that regional restrictions may apply, such as in England where only bread/flour mixes can be prescribed.
Other combinations, such as 2 kg bread, 1500 g pasta, and 2 kg oats, would result in double the recommended amount of gluten for a 3-year-old patient. It is also important to consider the patient’s age range, as the recommended amount of gluten varies for different age groups.
In summary, determining the correct gluten prescription for a patient involves following the National Prescribing Guidelines, considering regional restrictions, and taking into account the patient’s age range.

You are requested to assess a patient with generalized anxiety disorder (GAD) who has been on sertraline for the past 6 months. They have previously attempted citalopram with minimal improvement. The patient complains of persistent anxiety, chest tightness, and palpitations and wishes to explore a different medication. What would be the most suitable medication to recommend for this patient?
Your Answer: Mirtazapine
Correct Answer: Duloxetine
Explanation:If sertraline is ineffective or not tolerated as a first-line SSRI for GAD, consider trying another SSRI or an SNRI. The recommended medication in this case would be duloxetine. Since the patient has already tried citalopram with little benefit, it would not be appropriate to prescribe it again. Clomipramine, a tricyclic antidepressant, is not typically recommended for GAD management. Diazepam, a benzodiazepine, is also not recommended for GAD treatment due to the risk of tolerance and addiction.
Anxiety is a common disorder that can manifest in various ways. According to NICE, the primary feature is excessive worry about multiple events associated with heightened tension. It is crucial to consider potential physical causes when diagnosing anxiety disorders, such as hyperthyroidism, cardiac disease, and medication-induced anxiety. Medications that may trigger anxiety include salbutamol, theophylline, corticosteroids, antidepressants, and caffeine.
NICE recommends a step-wise approach for managing generalised anxiety disorder (GAD). This includes education about GAD and active monitoring, low-intensity psychological interventions, high-intensity psychological interventions or drug treatment, and highly specialist input. Sertraline is the first-line SSRI for drug treatment, and if it is ineffective, an alternative SSRI or a serotonin-noradrenaline reuptake inhibitor (SNRI) such as duloxetine or venlafaxine may be offered. If the patient cannot tolerate SSRIs or SNRIs, pregabalin may be considered. For patients under 30 years old, NICE recommends warning them of the increased risk of suicidal thinking and self-harm and weekly follow-up for the first month.
The management of panic disorder also follows a stepwise approach, including recognition and diagnosis, treatment in primary care, review and consideration of alternative treatments, review and referral to specialist mental health services, and care in specialist mental health services. NICE recommends either cognitive behavioural therapy or drug treatment in primary care. SSRIs are the first-line drug treatment, and if contraindicated or no response after 12 weeks, imipramine or clomipramine should be offered.

A 6-year-old boy came to the clinic with a painful left little finger following a door being shut on it. Upon examination, an X-ray revealed a fracture line that passes through the metaphysis, growth plate, and epiphysis. What classification of fracture is this?
Your Answer: Salter Harris 5
Correct Answer: Salter Harris 4
Explanation:A Salter-Harris type 4 fracture involves the physis, metaphysis, and epiphysis.
Paediatric Fractures and Pathological Conditions
Paediatric fractures can be classified into different types based on the injury pattern. Complete fractures occur when both sides of the cortex are breached, while greenstick fractures only have a unilateral cortical breach. Buckle or torus fractures result in incomplete cortical disruption, leading to a periosteal haematoma. Growth plate fractures are also common in paediatric practice and are classified according to the Salter-Harris system. Injuries of Types III, IV, and V usually require surgery and may be associated with disruption to growth.
Non-accidental injury is a concern in paediatric fractures, especially when there is a delay in presentation, lack of concordance between proposed and actual mechanism of injury, multiple injuries, injuries at sites not commonly exposed to trauma, or when children are on the at-risk register. Pathological fractures may also occur due to genetic conditions such as osteogenesis imperfecta, which is characterized by defective osteoid formation and failure of collagen maturation in all connective tissues. Osteopetrosis is another pathological condition where bones become harder and more dense, and radiology reveals a lack of differentiation between the cortex and the medulla, described as marble bone.
Overall, paediatric fractures and pathological conditions require careful evaluation and management to ensure optimal outcomes for the child.

A 56-year-old homeless man is discovered unresponsive on the pavement. Upon arrival at the emergency department, blood tests are conducted, revealing an abnormality - Amylase 1100 U/l. An ultrasound is performed, indicating no biliary tree dilatation. What is the probable reason for this man's condition?
Your Answer: Hypothermia
Explanation:Acute pancreatitis is a condition that is mainly caused by gallstones and alcohol in the UK. A popular mnemonic to remember the causes is GET SMASHED, which stands for gallstones, ethanol, trauma, steroids, mumps, autoimmune diseases, scorpion venom, hypertriglyceridaemia, hyperchylomicronaemia, hypercalcaemia, hypothermia, ERCP, and certain drugs. CT scans of patients with acute pancreatitis show diffuse parenchymal enlargement with oedema and indistinct margins. It is important to note that pancreatitis is seven times more common in patients taking mesalazine than sulfasalazine.

A 6-year-old girl comes to the GP with a pink spotted rash on her torso that has spread to all her limbs. Her mother reports that she had a high fever for three days before the rash appeared, and that she seemed to be improving before that. The girl is now without a fever.
During the examination, the GP observes a maculopapular red rash on the girl's trunk and limbs. All other aspects of the examination are normal, and her vital signs are stable.
What is the probable diagnosis?Your Answer: Erythema multiforme
Correct Answer: Roseola infantum
Explanation:Roseola infantum begins with a high fever that disappears before the rash appears. The rash starts suddenly after the temperature drops and usually starts on the trunk before spreading to the limbs. It is a non-itchy maculopapular rash.
Measles rash occurs with other systemic symptoms and usually starts on the face before spreading to other parts of the body. The characteristic ‘koplik spots’ are a classic sign of this illness.
Chickenpox starts as a red, itchy papular rash that becomes vesicular and can appear anywhere on the body.
Erythema multiforme is not caused by a virus but is a hypersensitivity reaction to herpes 7 virus. The macules are typically larger than other rashes and can progress to plaque-like lesions.
Hand, foot, and mouth disease is caused by the Coxsackie A6 virus and is characterized by painful vesicular lesions on the palms, soles, and buccal mucosa.
Understanding Roseola Infantum
Roseola infantum, also known as exanthem subitum or sixth disease, is a common illness that affects infants and is caused by the human herpes virus 6 (HHV6). This disease has an incubation period of 5-15 days and is typically seen in children aged 6 months to 2 years. The most common symptoms of roseola infantum include a high fever that lasts for a few days, followed by a maculopapular rash. Other symptoms may include Nagayama spots, which are papular enanthems on the uvula and soft palate, as well as cough and diarrhea.
In some cases, febrile convulsions may occur in around 10-15% of children with roseola infantum. While this can be concerning for parents, it is important to note that this is a common occurrence and typically resolves on its own. Additionally, HHV6 infection can lead to other possible consequences such as aseptic meningitis and hepatitis.
It is important to note that school exclusion is not necessary for children with roseola infantum. While this illness can be uncomfortable for infants, it is typically not serious and resolves on its own within a few days.

A 57-year-old motorcyclist is involved in a road traffic accident and suffers a displaced femoral shaft fracture. No other injuries are found during the primary or secondary surveys. The fracture is treated with closed, antegrade intramedullary nailing. The next day, the patient becomes increasingly confused and agitated. Upon examination, he is pyrexial, hypoxic with SaO2 at 90% on 6 litres O2, tachycardic, and normotensive. A non-blanching petechial rash is observed over the torso during systemic examination. What is the most probable explanation for this?
Your Answer: Fat embolism
Explanation:This individual displays physical indications and a recent injury that are consistent with fat embolism syndrome. In the early stages, meningococcal sepsis is not commonly linked to hypoxia. Likewise, pyrexia is not typically associated with pulmonary emboli.
Understanding Fat Embolism: Diagnosis, Clinical Features, and Treatment
Fat embolism is a medical condition that occurs when fat globules enter the bloodstream and obstruct blood vessels. This condition is commonly seen in patients with long bone fractures, particularly in the femur and tibia. The diagnosis of fat embolism is based on clinical features, including respiratory symptoms such as tachypnea, dyspnea, and hypoxia, as well as dermatological symptoms such as a red or brown petechial rash. CNS symptoms such as confusion and agitation may also be present. Imaging may not always show vascular occlusion, but a ground glass appearance may be seen at the periphery.
Prompt fixation of long bone fractures is crucial in the treatment of fat embolism. However, there is some debate regarding the benefit versus risk of medullary reaming in femoral shaft or tibial fractures in terms of increasing the risk of fat embolism. DVT prophylaxis and general supportive care are also important in the management of this condition. While fat embolism can be a serious and potentially life-threatening condition, prompt diagnosis and treatment can improve outcomes for patients.
