A 45-year-old man with dyspepsia and a history of recurrent peptic ulcer disease presents with intractable watery diarrhoea and weight loss. He has multiple gastric and duodenal peptic ulcers, which are poorly responding to medications such as antacids and omeprazole. Gastric acid output and serum gastrin level are elevated. Serum gastrin level fails to decrease following a test meal. On abdominal computerised tomography (CT) scan, no masses are found in the pancreas or duodenum.
Which one of the following drugs is useful for this patient?Your Answer: Somatostatin antagonist
Correct Answer: Octreotide
Explanation:Treatment Options for Gastrinoma: Octreotide, Somatostatin Antagonist, Bromocriptine, Pergolide, and Leuprolide
Gastrinoma is a rare condition characterized by multiple, recurrent, and refractory peptic ulcer disease, along with watery diarrhea and weight loss. The diagnosis is supported by an elevated serum gastrin level that is not suppressed by the test meal. While neoplastic masses of gastrinoma may or may not be localized by abdominal imaging, treatment options are available.
Octreotide, a synthetic somatostatin, is useful in the treatment of gastrinoma, acromegaly, carcinoid tumor, and glucagonoma. Somatostatin is an inhibitory hormone in several endocrine systems, and a somatostatin antagonist would increase gastrin, growth hormone, and glucagon secretion. However, it has no role in the treatment of gastrinoma.
Bromocriptine, a dopamine agonist, is used in the treatment of Parkinson’s disease, hyperprolactinemia, and pituitary tumors. Pergolide, another dopamine receptor agonist, was formerly used in the treatment of Parkinson’s disease but is no longer administered due to its association with valvular heart disease. Neither medication has a role in the treatment of gastrinoma.
Leuprolide, a gonadotropin-releasing hormone (GnRH) receptor agonist, is used in the treatment of sex hormone-sensitive tumors such as prostate or breast cancer. It also has no role in the treatment of gastrinoma. Overall, octreotide remains the primary treatment option for gastrinoma.

A 42-year-old man, who is a heavy drinker, presents with massive haematemesis. His vital signs are: pulse = 110 bpm, blood pressure = 80/40 mmHg, temperature = 36.8 °C and respiratory rate = 22 breaths per minute. On physical examination in the Emergency Department, he is noted to have gynaecomastia and caput medusae.
Which of the following conditions is most likely causing the haematemesis?Your Answer: Oesophageal varices
Explanation:Gastrointestinal Conditions: Understanding Oesophageal Varices, Hiatus Hernia, Mallory-Weiss Tear, Barrett’s Oesophagus, and Oesophageal Stricture
Gastrointestinal conditions can cause discomfort and even life-threatening complications. Here are five conditions that affect the oesophagus:
Oesophageal Varices: These are enlarged veins in the lower third of the oesophagus that can rupture and cause severe bleeding. They are often caused by portal hypertension, which is associated with chronic liver disease.
Hiatus Hernia: This condition occurs when the diaphragmatic crura separate, causing the stomach to protrude above the diaphragm. There are two types: axial and non-axial. Bleeding with a hiatus hernia is usually not severe.
Mallory-Weiss Tear: This condition is characterized by tears in the oesophageal lining caused by prolonged vomiting. It presents with bright red haematemesis.
Barrett’s Oesophagus: This condition is associated with reflux, inflammation, and possible ulceration. Bleeding is not usually severe.
Oesophageal Stricture: This condition results from scarring, typically caused by reflux or scleroderma. It is a chronic process that does not usually cause severe bleeding.
Understanding these conditions can help individuals recognize symptoms and seek appropriate medical attention.

A 30-year-old primiparous woman who is 10 weeks pregnant is curious about iron supplementation. Her blood tests reveal a Hb level of 110 g/L. What is the appropriate Hb cut-off for initiating treatment in this patient?
Your Answer: 115
Correct Answer: 110
Explanation:During pregnancy, women are checked for anaemia twice – once at the initial booking visit (usually around 8-10 weeks) and again at 28 weeks. The National Institute for Health and Care Excellence (NICE) has set specific cut-off levels to determine if a pregnant woman requires oral iron therapy. These levels are less than 110 g/L in the first trimester, less than 105 g/L in the second and third trimesters, and less than 100 g/L postpartum.
If a woman’s iron levels fall below these cut-offs, she will be prescribed oral ferrous sulfate or ferrous fumarate. It is important to continue this treatment for at least three months after the iron deficiency has been corrected to allow the body to replenish its iron stores. By following these guidelines, healthcare professionals can help ensure that pregnant women receive the appropriate care to prevent and manage anaemia during pregnancy.

A 47-year-old man visits his General Practitioner with worsening anxiety. He describes one of his symptoms as feeling severely nauseous and even vomiting every time he smells a particular perfume. What theory of learning explains this?
Your Answer: Operant conditioning
Correct Answer: Classical conditioning
Explanation:Types of Learning and Conditioning in Psychology
Classical conditioning, latent inhibition, habituation, operant conditioning, and tolerance are all types of learning and conditioning in psychology.
Classical conditioning involves learning through association, where an unfamiliar stimulus becomes associated with a conditioned response through repetitive exposure.
Latent inhibition refers to the slower acquisition of meaning or response to a familiar stimulus compared to a new stimulus.
Habituation is the decrease in responsiveness to a stimulus with repeated exposure.
Operant conditioning involves learning through positive or negative reinforcement, where a voluntary response is followed by a reinforcing stimulus.
Tolerance is the reduced response to a drug over time, requiring a higher concentration to achieve the desired effect.

You are an FY2 doctor in General Practice and have been asked to examine a lady who is 28 weeks pregnant as part of a routine antenatal check-up. She appears comfortable and her pregnancy has been uneventful so far.
Which of these should be part of a routine antenatal examination?Your Answer: Fetal heart rate with hand-held doppler ultrasound
Correct Answer: Symphysis-fundal height
Explanation:Antenatal Examinations: What to Expect and When
During pregnancy, regular antenatal examinations are important to monitor the health and development of both the mother and the fetus. Here are some key points to keep in mind:
Symphysis-fundal height: This measurement should be taken at every antenatal appointment from 24 weeks of gestation onwards.
Blood pressure and urine dipstick: These should be checked at every antenatal examination, especially in late pregnancy when pre-eclampsia is more common.
Abdominal palpation for fetal presentation: This should only be done at or after 36 weeks of gestation, as it is more accurate and can influence management of delivery. If an abnormal presentation is suspected, an ultrasound scan should be performed.
Ultrasound scan: Routine scanning after 24 weeks of gestation is not recommended.
Fetal movement counting: This is not routinely offered.
Fetal heart rate with hand-held doppler ultrasound: Routine auscultation is not recommended, but may be done to reassure the mother if requested.
By following these guidelines, healthcare providers can ensure that antenatal examinations are conducted safely and effectively.

A 75-year-old male has been diagnosed with rectal carcinoma and is scheduled for a lower anterior resection with the goal of restoring intestinal continuity. What type of stoma would be most suitable?
Your Answer: Loop ileostomy
Explanation:The loop ileostomy is a technique used to redirect the flow of bowel contents away from a distal anastomosis, typically in cases of rectal cancer. When the ileostomy is reversed, it allows for the restoration of bowel continuity and can greatly enhance the patient’s quality of life.
Abdominal stomas are created during various abdominal procedures to bring the lumen or contents of organs onto the skin. Typically, this involves the bowel, but other organs may also be diverted if necessary. The type and method of construction of the stoma will depend on the contents of the bowel. Small bowel stomas should be spouted to prevent irritant contents from coming into contact with the skin, while colonic stomas do not require spouting. Proper siting of the stoma is crucial to reduce the risk of leakage and subsequent maceration of the surrounding skin. The type and location of the stoma will vary depending on the purpose, such as defunctioning the colon or providing feeding access. Overall, abdominal stomas are a necessary medical intervention that requires careful consideration and planning.

A 30-year-old woman who leads an active lifestyle visits her doctor for a routine work-related health check-up. During the check-up, her urinalysis shows a positive result for protein (+) and a 24-hour urine collection is ordered. The results reveal a urine protein level of 25 mg/24 hours. What recommendations should be provided to the patient?
Your Answer: This result is within normal limits
Explanation:Proteinuria and its Significance in Patient Assessment
Proteinuria is a condition where protein is present in the urine, which can be an indicator of kidney disease or other underlying health issues. When assessing a patient with suspected proteinuria, it is important to consider their age, activity levels, and the presence of diseases such as diabetes.
Urine albumin levels of 30-300 mg/24 hours are considered microalbuminuria, which is a marker of cardiovascular risk and can predict chronic kidney disease, especially in patients with diabetes. This is usually estimated using the albumin-creatinine ratio (ACR), where an ACR of >3.5 mg/mmol in women or >2.5 mg/mmol in men is considered abnormal. Albuminuria is defined as >300 mg/24 hours or an ACR of >30 mg/mmol.
In some patients, particularly young adults, low-level proteinuria (140 mg – 1 g /24 hours) can be normal and may be caused by factors such as exercise, postural changes, or a high protein diet. However, urine microscopy should be done to exclude casts or cells. Proteinuria levels of 1-2 g/24 hours are more concerning and can be a sign of developing kidney disease such as glomerulonephritis.
If proteinuria levels exceed 3 g/24 hours, it is diagnostic of nephrotic syndrome and requires admission to the hospital for further investigation and management. Some authorities use a cut-off of 3.5 g/24 hours in this case. the significance of proteinuria levels is crucial in patient assessment and can aid in the early detection and management of kidney disease and other underlying health issues.
Overall, proteinuria levels should be carefully monitored and evaluated in the context of the patient’s overall health and medical history.

A 76-year-old male presents with a one day history of abdominal distension and vomiting.
Upon examination, there is an irreducible lump in the right groin arising below and lateral to the pubic tubercle. A plain abdominal radiograph reveals distended loops of small bowel.
Which of the following hernias are most likely to have caused these symptoms?Your Answer: Indirect inguinal
Correct Answer: Femoral
Explanation:Small Bowel Obstruction and Femoral Hernias
This patient is experiencing a small bowel obstruction, which is likely caused by an obstructed femoral hernia. The lump in the left groin that cannot be reduced arises below and lateral to the pubic tubercle, indicating a femoral hernia rather than an inguinal hernia, which would produce a lump above and medial to the pubic tubercle. Femoral hernias are the third most common type of hernia, with a higher incidence in elderly multiparous women. It is important to repair all femoral hernias, as 40% of cases are strangulated upon initial presentation. If the overlying skin becomes erythematosus, it is a sign of poor outcome. Obturator hernias are rare and typically do not present with a lump.
Overall, it is crucial to identify the type of hernia causing a small bowel obstruction in order to provide appropriate treatment. Femoral hernias, in particular, require prompt repair to prevent strangulation and potential complications.

What could be the possible reason for these FBC results in a 65-year-old male?Your Answer: Ethanol abuse
Correct Answer: Gastrointestinal blood loss
Explanation:Microcytic Anaemia in a 63-Year-Old Female
A Full Blood Count (FBC) analysis has revealed that a 63-year-old female is suffering from microcytic anaemia, which is characterized by low mean corpuscular volume (MCV) and low haemoglobin (Hb) levels. This type of anaemia is typically caused by iron deficiency, which is often the result of blood loss. However, in this case, menorrhagia can be ruled out as the patient is postmenopausal. Therefore, the most likely cause of the microcytic anaemia is peptic ulceration. It is important to note that pernicious anaemia or folate deficiency can cause macrocytosis, which is characterized by elevated MCV levels. Proper diagnosis and treatment are necessary to address the underlying cause of the microcytic anaemia and prevent further complications.

Which patient is diagnosed with nephrotic syndrome?Your Answer: Celia Creutzfeldt
Correct Answer: Bella Barnard
Explanation:Nephrotic Syndrome
Nephrotic syndrome is a condition characterized by low serum albumin levels, high urinary protein levels, and marked pitting edema. Only individuals who meet all three criteria are diagnosed with this syndrome. Other features of nephrotic syndrome include little or no hematuria, glomerular pathology as the cause, marked hyperlipidemia that increases cardiovascular risk, reduced immunoglobulins that increase the risk of infection, and loss of certain proteins that increase the risk of thrombosis, including renal vein thrombosis. Creatinine levels can be normal or elevated.
The causes of nephrotic syndrome include glomerulonephritis, such as minimal change disease and membranous glomerulonephritis, focal segmental glomerulosclerosis, diabetic nephropathy, amyloid (AL form), and connective tissue disease such as systemic lupus erythematosus. the diagnostic criteria and features of nephrotic syndrome is crucial for early detection and management of this condition.

A 15-year-old girl arrives at the Emergency department with breathing difficulties. Earlier that day, she had visited her general practitioner for a sore throat and was diagnosed with tonsillitis. The doctor prescribed a five-day course of oral amoxicillin. The patient has a history of ulcerative colitis and takes mesalazine 400 mg tds regularly.
Upon examination, the girl appears distressed with laboured breathing and stridor. She is pale, sweaty, and cyanosed, sitting up with an open mouth and drooling saliva. Her temperature is 39°C, pulse 120/minute and regular, blood pressure 90/35 mmHg. Her lungs are clear.
What is the immediate treatment required for this patient?Your Answer: Endotracheal intubation
Explanation:Acute Epiglottitis: Diagnosis and Management
Acute epiglottitis is a possible diagnosis when a patient presents with sudden airway obstruction. It is crucial to seek the assistance of an anaesthetist immediately as attempting to visualize the inflamed epiglottis without proper expertise may cause acute airway obstruction. The diagnosis can be confirmed by directly visualizing a cherry-red epiglottis. Early intubation is necessary, especially when respiratory distress is present. Although adult epiglottitis is rare, it has a higher mortality rate.
In summary, acute epiglottitis is a serious condition that requires prompt diagnosis and management. It is essential to involve an anaesthetist and avoid touching the inflamed tissue until proper expertise is present. Early intubation is crucial, and adult epiglottitis should be considered in patients with respiratory distress.

To visualize the vocal cords, where should the tip of a Macintosh laryngoscope be inserted?
Your Answer: Posterior to the epiglottis
Correct Answer: Into the vallecula
Explanation:Macintosh Laryngoscope: A Tool for Visualizing the Vocal Cords
The Macintosh laryngoscope is a medical instrument designed to aid in the visualization of the vocal cords. Its curved blade is specifically shaped to fit into the oral and oropharyngeal cavity. To use it, the blade is inserted through the right side of the mouth and gradually advanced, pushing the tongue to the left and out of view. The blade has a small bulbous tip that is intended to sit in the vallecula, a small depression between the base of the tongue and the epiglottis.
By lifting the laryngoscope up and forwards, the larynx is elevated, allowing for a clear view of the vocal cords. This tool is commonly used in medical settings, such as during intubation procedures or when examining the airway. Its design allows for a safe and effective way to visualize the vocal cords, aiding in the diagnosis and treatment of various medical conditions.

Tests:
Fasting plasma glucose: 6.5 mmol/l
Fundoscopy: Bilateral drusen affecting the fovea
Visual field testing: Bilateral central visual field loss
Fluorescein angiography: Bilateral retinal neovascularisation and exudates present
What is the most appropriate diagnosis for this patient's symptoms and test results?Your Answer: Diabetic retinopathy
Correct Answer: Age-related macular degeneration (AMD)
Explanation:Understanding Age-Related Macular Degeneration (AMD)
Age-related macular degeneration (AMD) is a common condition among individuals aged 75 years and above. It is characterized by the presence of yellow spots called drusen, which are waste products from the retinal pigment epithelium. Gradual loss of central vision, as well as the presence of foveal drusen on retinal examination, are typical signs of AMD. There are two types of AMD: wet (neovascular) and dry (non-neovascular). Dry AMD progresses slowly and has no known treatment, although stopping smoking can reduce its rate of progression. Wet AMD, on the other hand, arises when there is choroidal neovascularization and can be treated with laser treatment or anti-VEGF intravitreal injections to reduce new vessel formation.
Other eye conditions that may cause vision loss include diabetic maculopathy, proliferative retinopathy (PR), hypertensive retinopathy, diabetic retinopathy, retinitis pigmentosa, and chronic angle closure glaucoma. However, the patient’s symptoms and retinal examination findings suggest that AMD is the most likely diagnosis. It is important to understand the different eye conditions and their respective treatments to provide appropriate care and management for patients.

Which one of the following statements regarding toddler spasms is incorrect?
Your Answer: Causes characteristic 'salaam' attacks
Correct Answer: Carries a good prognosis
Explanation:Understanding Infantile Spasms
Infantile spasms, also known as West syndrome, is a form of epilepsy that typically occurs in infants between 4 to 8 months old, with a higher incidence in male infants. This condition is often associated with a serious underlying condition and has a poor prognosis. The characteristic feature of infantile spasms is the salaam attacks, which involve the flexion of the head, trunk, and arms followed by the extension of the arms. These attacks last only 1-2 seconds but can be repeated up to 50 times.
Infants with infantile spasms may also experience progressive mental handicap. To diagnose this condition, an EEG is typically performed, which shows hypsarrhythmia in two-thirds of infants. Additionally, a CT scan may be used to identify any diffuse or localized brain disease, which is present in 70% of cases, such as tuberous sclerosis.
Unfortunately, infantile spasms carry a poor prognosis. However, there are treatment options available. Vigabatrin is now considered the first-line therapy, and ACTH is also used.

A 75-year-old woman comes in with weight loss and a serum calcium concentration of 3.22 mmol/l (normal range 2.1-2.8 mmol/l). Her skeletal survey shows no abnormalities. The doctors suspect non-metastatic hypercalcaemia. What is the probable substance being produced by the tumor?
Your Answer: Parathyroid hormone-related peptide (PTHrP)
Explanation:Causes of Hypercalcaemia in Cancer Patients
Hypercalcaemia is a common occurrence in cancer patients, affecting around 10-20% of cases. It is caused by increased bone resorption and release of calcium from bone. The most common cancers associated with hypercalcaemia are breast and lung cancers, as well as multiple myeloma.
One of the most common causes of hypercalcaemia in patients with non-metastatic solid tumours is the secretion of parathyroid hormone-related peptide (PTHrP), also known as humoral hypercalcaemia of malignancy. This should be suspected in any patient with a solid tumour in the absence of bony metastases or in patients with unexplained hypercalcaemia and low serum PTH concentration. PTHrP is related in function to PTH and is most commonly secreted by breast and lung tumours.
Osteoclast-activating cytokines can also cause osteolytic metastases and release of calcium. Calcitonin is used to lower plasma calcium concentration in patients with hypercalcaemia associated with malignancy. Calcitriol is the cause of almost all cases of hypercalcaemia in Hodgkin’s disease and approximately one-third of cases in non-Hodgkin’s lymphoma. Secretion of PTH as a cause is rare, and serum PTH concentrations are typically low.
In conclusion, hypercalcaemia in cancer patients can have various causes, and it is important to identify the underlying cause to provide appropriate treatment.

You are crash-paged to his bedside in response to his having a cardiac arrest.
What is the most appropriate management?Your Answer:
Correct Answer: Initiate CPR, give a fibrinolytic and continue for at least 60 minutes
Explanation:Management of Cardiac Arrest in a Post-Operative Patient with a History of Cancer and Oral Contraceptive Use
In the management of a patient who experiences cardiac arrest, it is important to consider the underlying cause and initiate appropriate interventions. In the case of a post-operative patient with a history of cancer and oral contraceptive use, thrombosis is a likely cause of cardiac arrest. Therefore, CPR should be initiated and a fibrinolytic such as alteplase should be given. CPR should be continued for at least 60 minutes as per Resuscitation Council (UK) guidelines.
Giving adrenaline without initiating CPR would not be appropriate. It is important to rule out other potential causes such as hypovolemia, hypoxia, tamponade, tension pneumothorax, and toxins. However, in this scenario, thrombosis is the most likely cause.
Calling cardiology for pericardiocentesis is not indicated as there is no history of thoracic trauma. Informing the family is important, but initiating CPR should take priority. Prolonged resuscitation of at least 60 minutes is warranted in the case of thrombosis. Overall, prompt and appropriate management is crucial in the event of cardiac arrest.

A 35-year-old woman has been experiencing cyclical mood swings and irritability, which typically occur one week before her period and subside a few days after. She visited her GP, who prescribed a combined oral contraceptive pill (COCP) after reviewing her symptom diary. However, after three months of treatment, she returns to her GP and reports that her symptoms have not improved during her menstrual cycle. She is feeling like a bad mother as she is losing her patience with her children easily when symptomatic and is seeking further treatment options. What is the most appropriate treatment for her?
Your Answer:
Correct Answer: Sertraline
Explanation:Premenstrual syndrome (PMS) can be helped by SSRIs, either continuously or during the luteal phase. If a patient’s symptoms are significantly impacting their day-to-day life and have not improved with first-line treatment using a combined oral contraceptive pill, antidepressant treatment with SSRIs is recommended. Co-cyprindiol, levonorgestrel-releasing intrauterine systems, mirtazapine, and the copper coil are not indicated for the management of PMS.
Understanding Premenstrual Syndrome (PMS)
Premenstrual syndrome (PMS) is a condition that affects women during the luteal phase of their menstrual cycle. It is characterized by emotional and physical symptoms that can range from mild to severe. PMS only occurs in women who have ovulatory menstrual cycles and does not occur before puberty, during pregnancy, or after menopause.
Emotional symptoms of PMS include anxiety, stress, fatigue, and mood swings. Physical symptoms may include bloating and breast pain. The severity of symptoms varies from woman to woman, and management options depend on the severity of symptoms.
Mild symptoms can be managed with lifestyle advice, such as getting enough sleep, exercising regularly, and avoiding smoking and alcohol. Specific advice includes eating regular, frequent, small, balanced meals that are rich in complex carbohydrates.
Moderate symptoms may benefit from a new-generation combined oral contraceptive pill (COCP), such as Yasmin® (drospirenone 3 mg and ethinylestradiol 0.030 mg). Severe symptoms may benefit from a selective serotonin reuptake inhibitor (SSRI), which can be taken continuously or just during the luteal phase of the menstrual cycle (for example, days 15-28, depending on the length of the cycle). Understanding PMS and its management options can help women better cope with this common condition.

A 29-year-old woman presents with hypertension at 12 weeks into her pregnancy. She has no history of hypertension. She complains of headache and tenderness in the right lower quadrant. An ultrasound of her pelvis reveals multiple cysts in both ovaries. There are no signs of hirsutism or virilism. What is the most probable diagnosis?
Your Answer:
Correct Answer: Molar pregnancy
Explanation:Possible Causes of Hirsutism in Women: A Differential Diagnosis
Hirsutism, the excessive growth of hair in women in a male pattern, can be caused by various underlying conditions. Here are some possible causes and their distinguishing features:
Molar Pregnancy: This condition is characterized by hypertension in the first trimester of pregnancy. Excessive stimulation of ovarian follicles by high levels of gonadotrophins or human chorionic gonadotrophin (hCG) can lead to the formation of multiple theca lutein cysts bilaterally.
Congenital Adrenal Hyperplasia: This disease, which is mostly found in women, can present with gradual onset of hirsutism without virilization. It is caused by a deficiency of 21-hydroxylase and is characterized by an elevated serum concentration of 17-hydroxyprogesterone.
Luteoma of Pregnancy: This benign, solid ovarian tumor develops during pregnancy and disappears after delivery. It may be associated with excess androgen production, leading to hirsutism and virilization.
Adrenal Tumor: Androgen-secreting adrenal tumors can cause rapid onset of severe hirsutism, with or without virilization. Amenorrhea is found in almost half of the patients, and testosterone and dihydrotestosterone sulfate concentrations are elevated.
Polycystic Ovary Syndrome: Women with this condition are at higher risk of developing pre-eclampsia. However, the development of hypertension in the first trimester of pregnancy makes it more likely that there is a molar pregnancy present, with theca lutein cysts seen on ultrasound.
In summary, hirsutism in women can be caused by various conditions, and a differential diagnosis is necessary to determine the underlying cause and appropriate treatment.

A 13-year-old boy experiences facial swelling and a red, itchy rash shortly after receiving his first dose of the HPV vaccine. Upon arrival, paramedics observe a bilateral expiratory wheeze and a blood pressure reading of 85/60 mmHg. According to the Gell and Coombs classification of hypersensitivity reactions, what type of reaction is this an example of?
Your Answer:
Correct Answer: Type I reaction
Explanation:Classification of Hypersensitivity Reactions
Hypersensitivity reactions are classified into four types according to the Gell and Coombs classification. Type I, also known as anaphylactic hypersensitivity, occurs when an antigen reacts with IgE bound to mast cells. This type of reaction is responsible for anaphylaxis and atopy, such as asthma, eczema, and hay fever. Type II, or cytotoxic hypersensitivity, happens when cell-bound IgG or IgM binds to an antigen on the cell surface. This type of reaction is associated with autoimmune hemolytic anemia, ITP, Goodpasture’s syndrome, and other conditions. Type III, or immune complex hypersensitivity, occurs when free antigen and antibody (IgG, IgA) combine to form immune complexes. This type of reaction is responsible for serum sickness, systemic lupus erythematosus, post-streptococcal glomerulonephritis, and extrinsic allergic alveolitis. Type IV, or delayed hypersensitivity, is T-cell mediated and is responsible for tuberculosis, graft versus host disease, allergic contact dermatitis, and other conditions.
In recent times, a fifth category has been added to the classification of hypersensitivity reactions. Type V hypersensitivity occurs when antibodies recognize and bind to cell surface receptors, either stimulating them or blocking ligand binding. This type of reaction is associated with Graves’ disease and myasthenia gravis. Understanding the different types of hypersensitivity reactions is important in diagnosing and treating various conditions. Proper identification of the type of reaction can help healthcare professionals provide appropriate treatment and management strategies.

What is a common clinical feature of hyperthyroidism?
Your Answer:
Correct Answer: Heat intolerance
Explanation:Thyroid Disorders
Thyroid disorders are characterized by the dysfunction of the thyroid gland, which can lead to a variety of symptoms. Hypothyroidism, for example, is marked by weight gain, bradycardia, and dry skin. On the other hand, hyperthyroidism is the excess secretion of thyroid hormones, which can stimulate basal metabolic rate and heighten catecholamine sensitivity. The three most common causes of primary hyperthyroidism are Graves’ disease, toxic adenoma, and toxic multinodular goitre. Other causes include de Quervain’s (post-viral) thyroiditis and drugs such as amiodarone.
One of the key symptoms of thyroid disorders is polydipsia, which refers to excessive thirst. Excess levothyroxine ingestion can also cause a biochemical picture similar to primary thyroid disease, with a suppression of thyroid-stimulating hormone and an elevated free thyroxine (T4) in plasma. It is important to understand the different types of thyroid disorders and their causes in order to properly diagnose and treat them. By doing so, individuals can manage their symptoms and improve their overall quality of life.

A 35-year-old woman who is 30 weeks pregnant presents with malaise, headaches and vomiting. She is admitted to the obstetrics ward after a routine blood pressure measurement was 190/95 mmHg. Examination reveals right upper quadrant abdominal pain and brisk tendon reflexes. The following blood tests are shown:
Hb 85 g/l
WBC 6 * 109/l
Platelets 89 * 109/l
Bilirubin 2.8 µmol/l
ALP 215 u/l
ALT 260 u/l
γGT 72 u/l
LDH 846 u/I
A peripheral blood film is also taken which shows polychromasia and schistocytes. What is the most likely diagnosis?Your Answer:
Correct Answer: HELLP syndrome
Explanation:The symptoms of HELLP syndrome, a severe form of pre-eclampsia, include haemolysis (H), elevated liver enzymes (EL), and low platelets (LP). A patient with this condition may experience malaise, nausea, vomiting, and headache, as well as hypertension with proteinuria and epigastric and/or upper abdominal pain. The patient in this case meets the requirements for a diagnosis of HELLP syndrome.
Liver Complications During Pregnancy
During pregnancy, there are several liver complications that may arise. One of the most common is intrahepatic cholestasis of pregnancy, which occurs in about 1% of pregnancies and is typically seen in the third trimester. Symptoms include intense itching, especially in the palms and soles, as well as elevated bilirubin levels. Treatment involves the use of ursodeoxycholic acid for relief and weekly liver function tests. Women with this condition are usually induced at 37 weeks to prevent stillbirth, although maternal morbidity is not typically increased.
Another rare complication is acute fatty liver of pregnancy, which may occur in the third trimester or immediately after delivery. Symptoms include abdominal pain, nausea and vomiting, headache, jaundice, and hypoglycemia. Severe cases may result in pre-eclampsia. ALT levels are typically elevated, and support care is the primary management until delivery can be performed once the patient is stabilized.
Finally, conditions such as Gilbert’s and Dubin-Johnson syndrome may be exacerbated during pregnancy. Additionally, HELLP syndrome, which stands for haemolysis, elevated liver enzymes, and low platelets, is a serious complication that can occur in the third trimester and requires immediate medical attention. Overall, it is important for pregnant women to be aware of these potential liver complications and to seek medical attention if any symptoms arise.

A 72-year-old woman is brought to the Emergency Department from a nursing home with confusion, fever and flank pain. Her temperature is 38.5 °C, blood pressure 82/48 mmHg, pulse rate 123 bpm and respiration rate 27 breaths per minute. Physical examination reveals dry mucous membranes and flank tenderness. Urinalysis shows 50–100 leukocytes and many bacteria per high-powered field.
Which of the following is most likely to improve survival for this patient?Your Answer:
Correct Answer: Aggressive fluid resuscitation
Explanation:The Importance of Timing in Fluid Resuscitation for Severe Sepsis: Debunking Myths about Haemodynamic Monitoring, Albumin Infusion, and Haemoglobin Levels
When it comes to treating severe sepsis, timing is crucial. Aggressive fluid resuscitation within the first six hours can significantly improve a patient’s chances of survival. This was demonstrated in a landmark study by Rivers and colleagues, which found that early goal-directed therapy resulted in higher survival rates than delayed resuscitation attempts.
However, not all interventions are equally effective. Haemodynamic monitoring with a pulmonary artery catheter, for example, has not been shown to increase survival in septic patients. Similarly, there is no evidence that albumin infusion reduces mortality, and in fact, some studies have shown increased mortality rates in patients who received albumin solutions.
Maintaining a haemoglobin level above 120 g/l is also not supported by evidence. While giving blood may be part of resuscitation for anaemic patients in shock, aiming for a specific haemoglobin level is not necessary.
Finally, there is no data to support the idea that maintaining a lower Pa(CO2) would increase survival in septic patients. In summary, aggressive fluid resuscitation within the first six hours is crucial for treating severe sepsis, but not all interventions are equally effective or supported by evidence.

A 32-year-old woman presents with vaginal bleeding, abdominal pain, and right shoulder tip pain. She has a history of PID, a miscarriage, and two terminations. A urine pregnancy test confirms pregnancy. What is the most appropriate next step in management?
Your Answer:
Correct Answer: Admit as an emergency under the gynaecologists
Explanation:Ectopic Pregnancy: A Gynaecological Emergency
Ectopic pregnancy is a serious condition that requires immediate medical attention. It occurs when a fertilized egg implants outside the uterus, usually in the fallopian tube. This can lead to life-threatening complications if left untreated. Risk factors for ectopic pregnancy include a history of pelvic inflammatory disease (PID), previous terminations, and a positive pregnancy test.

A 57-year-old man presents to the Emergency department with sudden onset of chest pain, breathlessness, and palpitations. An admission ECG reveals ventricular tachycardia (VT) with a ventricular rate of 170 bpm. His blood pressure is 100/66 mmHg, and his oxygen saturations are 95% on air and 100% on high flow oxygen (15 L/min). His blood sugar level is 8.3 mmol/L. Despite his condition, he remains alert and able to communicate. The patient has a medical history of hypertension, type 2 diabetes, and asthma. The medical team administers intravenous amiodarone to attempt to stop the arrhythmia. What is the mandatory intervention while giving intravenous amiodarone?
Your Answer:
Correct Answer: Continuous ECG recording should be done via cardiac monitoring
Explanation:Amiodarone is an antiarrhythmic drug that prolongs the repolarisation phase of the action potential by modulating calcium and potassium permeability. It is useful in various cardiac arrhythmias but requires continuous ECG monitoring due to its negative chronotropic and dromotropic effects. Amiodarone is metabolised via the cytochrome P450 enzyme system and is contraindicated in bradycardia and second or third degree heart block. Rapid infusion can cause a significant drop in blood pressure and should be avoided. Amiodarone can cause pulmonary complications, so routine chest x-rays and follow-up radiographs are recommended. It does not affect glucose metabolism but can cause hypoglycaemia when used with some oral antidiabetic drugs.

A mother arrives with her 3-year-old son who was diagnosed with cow's milk protein allergy (CMPA) at 6 months old. He has been on a dairy-free diet and fed hydrolysed milk until he turned 1. Recently, he successfully completed the milk ladder and has been drinking raw milk for the past month without any reactions or diarrhoea. The mother is curious if this is typical or if her son was misdiagnosed earlier. IgE testing was conducted and came back normal. What advice would you give to the mother regarding her son's situation?
Your Answer:
Correct Answer: Milk tolerance is common by 3 years
Explanation:By the age of 3, most children with non-IgE-mediated cow’s milk protein allergy will become tolerant to milk. The milk ladder is designed to gradually expose children like Gabriel, who has normal IgE levels, to increasing levels of milk protein through their diet. Diagnosis of CMPA is based on clinical symptoms such as growth faltering, constipation, and irritability, and confirmed by withdrawal of cow’s milk protein-containing substances followed by re-exposure. Lactose intolerance is rare in children under 3 years old. Milk tolerance is not unusual in non-IgE mediated cow’s milk protein allergy by the age of 3.
Understanding Cow’s Milk Protein Intolerance/Allergy
Cow’s milk protein intolerance/allergy (CMPI/CMPA) is a condition that affects around 3-6% of children, typically presenting in the first 3 months of life in formula-fed infants. Both immediate and delayed reactions can occur, with CMPA used for immediate reactions and CMPI for mild-moderate delayed reactions. Symptoms include regurgitation, vomiting, diarrhea, urticaria, atopic eczema, colic symptoms, wheeze, chronic cough, and rarely, angioedema and anaphylaxis. Diagnosis is often clinical, with investigations including skin prick/patch testing and total IgE and specific IgE (RAST) for cow’s milk protein.
Management for formula-fed infants includes using extensive hydrolyzed formula (eHF) milk as the first-line replacement formula for mild-moderate symptoms and amino acid-based formula (AAF) for severe CMPA or if no response to eHF. Around 10% of infants are also intolerant to soya milk. For breastfed infants, mothers should eliminate cow’s milk protein from their diet and consider prescribing calcium supplements to prevent deficiency. eHF milk can be used when breastfeeding stops until at least 6 months and up to 12 months of age.
The prognosis for CMPI is usually good, with most children becoming milk tolerant by the age of 3-5 years. However, a challenge is often performed in a hospital setting as anaphylaxis can occur. It is important to refer infants with severe symptoms to a pediatrician for management. Understanding CMPI/CMPA and its management can help parents and healthcare providers provide appropriate care for affected children.

A multiparous woman at 38 weeks gestation is admitted to the labour ward after an artificial rupture of membranes. During four-hourly vaginal examinations, the midwife suddenly palpates the umbilical cord vaginally. The woman is placed on cardiotocography, which reveals late decelerations. What should be the midwife's next immediate step in managing the situation?
Your Answer:
Correct Answer: Push presenting part of the foetus back in
Explanation:In the case of an umbilical cord prolapse, it is important to push the presenting part of the fetus back into the uterus to prevent compression of the cord and subsequent fetal distress. This can be aided by retro-filling the bladder with saline and positioning the mother on all fours. Administering oxytocin infusion or tocolytics to stop uterine contractions is not recommended as they can worsen the situation. The McRoberts manoeuvre is also not applicable in this scenario. It is crucial to manage the situation promptly to prevent further harm to the fetus.
Understanding Umbilical Cord Prolapse
Umbilical cord prolapse is a rare but serious complication that can occur during delivery. It happens when the umbilical cord descends ahead of the presenting part of the fetus, which can lead to compression or spasm of the cord. This can cause fetal hypoxia and potentially irreversible damage or death. Certain factors increase the risk of cord prolapse, such as prematurity, multiparity, polyhydramnios, twin pregnancy, cephalopelvic disproportion, and abnormal presentations like breech or transverse lie.
Around half of all cord prolapses occur when the membranes are artificially ruptured. Diagnosis is usually made when the fetal heart rate becomes abnormal and the cord is palpable vaginally or visible beyond the introitus. Cord prolapse is an obstetric emergency that requires immediate management. The presenting part of the fetus may be pushed back into the uterus to avoid compression, and the cord should be kept warm and moist to prevent vasospasm. The patient may be asked to go on all fours or assume the left lateral position until preparations for an immediate caesarian section have been carried out. Tocolytics may be used to reduce uterine contractions, and retrofilling the bladder with saline can help elevate the presenting part. Although caesarian section is the usual first-line method of delivery, an instrumental vaginal delivery may be possible if the cervix is fully dilated and the head is low.
In conclusion, umbilical cord prolapse is a rare but serious complication that requires prompt recognition and management. Understanding the risk factors and appropriate interventions can help reduce the incidence of fetal mortality associated with this condition.

An 80-year-old retired teacher complains of headache and scalp tenderness. She reports experiencing blurred vision for the past three days. What signs suggest a possible diagnosis of giant cell arthritis?
Your Answer:
Correct Answer: Temporal artery biopsy demonstrating mononuclear cell infiltration
Explanation:Diagnosis of Giant Cell arthritis
Giant cell arthritis is a condition that affects the arteries, particularly those in the head and neck. To diagnose this condition, the American College of Rheumatology has developed criteria that require the fulfillment of at least three out of five criteria. These criteria have a 93% sensitivity of diagnosis.
The first criterion is age over 50, as this condition is more common in older individuals. The second criterion is the onset of a new type of localized headache, which is often severe and persistent. The third criterion is an elevated erythrocyte sedimentation rate (ESR) of over 50 mm/hr by the Westergreen method, which indicates inflammation in the body. The fourth criterion is temporal artery tenderness to palpation or decreased pulsation, which can be felt by a doctor during a physical exam. The fifth criterion is an arterial biopsy showing granulomatous inflammation or mononuclear cell infiltration, usually with multinucleated giant cells.
Overall, the diagnosis of giant cell arthritis requires a combination of clinical and laboratory findings. If a patient meets at least three of these criteria, further testing and treatment may be necessary to manage this condition.

A 42-year-old previously healthy teacher visits her doctor complaining of headache and itching. During her urine test, protein (3+) and blood (1+) are detected, but there are no splinter haemorrhages. What other bedside examination would be beneficial in evaluating her condition?
Your Answer:
Correct Answer: Blood pressure
Explanation:Assessment and Further Testing for Kidney Disease
Assessing kidney disease at the bedside involves several steps, including urinalysis, blood pressure measurement, and assessment of volume status. However, further testing is necessary to confirm the diagnosis and determine the underlying cause of the disease. Blood testing for U&Es, autoantibodies, glucose, HbA1c, complement, and ANCA serology, as well as hepatitis and HIV viral screening, can provide valuable information.
In this case, the patient presents with features consistent with kidney disease, including an abnormal urinalysis. While diabetes could be a possible cause, the patient’s age makes it less likely. Therefore, additional testing is necessary to determine the underlying cause of the disease. Checking the patient’s blood pressure is also important, as hypertension is often associated with renal diseases. Aggressive management of hypertension can help prevent the progression of chronic renal failure.

A 40-year-old man falls while skiing. He presents to your clinic with weakness of pincer grip and pain and laxity on valgus stress of his thumb. What is the most probable injury?
Your Answer:
Correct Answer: Ulnar collateral ligament of the thumb injury
Explanation:There are several injuries that can affect the thumb and wrist. One common injury is a Ulnar collateral ligament (UCL) injury, also known as skier’s/gamekeeper’s thumb. This injury occurs when the thumb is forcefully abducted, causing damage to the UCL of the metacarpophalangeal joint. Symptoms include weak pincer grip, reduced range of motion, swelling, and burning pain. Treatment involves immobilization with a thumb spica, and surgery may be necessary for complete UCL rupture.
Another injury is a scaphoid fracture, which often occurs in older individuals who fall onto outstretched arms. Symptoms include pain and swelling in the anatomical snuff box, reduced range of motion, and pain with wrist and thumb movement. Fractures in the proximal one-third of the bone or displaced fractures may require surgery to prevent avascular necrosis.
Extensor pollicis longus strain is another injury that can occur from repetitive thumb and wrist extension, such as in manual labor or gardening. Symptoms include pain over the thumb and dorsal wrist, worsened with palpation and extension. Treatment involves rest, ice, and pain relief.
De Quervain’s tenosynovitis is an inflammation of the extensor pollicis brevis and abductor pollicis longus tendons, which pass through the first dorsal compartment. Symptoms include pain and swelling on the lateral aspect of the wrist, and pain is reproduced with Finkelstein’s test.
Finally, Bennett’s fracture is a less common injury that often occurs in boxing and can lead to osteoarthritis later in life. It is an intra-articular fracture of the first metacarpal bone, causing pain, bruising, swelling, and difficulty with pincer grip. Treatment may involve open reduction and fixation if there is significant displacement.

An 80-year-old man presented with progressive dyspepsia and weight loss. Endoscopy revealed a stenosing lesion that bled easily. A biopsy and histopathological examination revealed adenocarcinoma of the oesophagus.
Which of the following is the most likely aetiological factor?Your Answer:
Correct Answer: Gastro-oesophageal reflux disease (GORD)
Explanation:Factors Contributing to Oesophageal Cancer
Oesophageal cancer is a common and aggressive tumour that can be caused by various factors. The two most common types of oesophageal cancer are squamous cell carcinoma and adenocarcinoma. In developed countries, adenocarcinoma is more prevalent, while squamous cell carcinoma is more common in the developing world.
Gastro-oesophageal reflux disease (GORD) is the most common predisposing factor for oesophageal adenocarcinoma. Acid reflux can cause irritation that progresses to metaplasia, dysplasia, and eventually adenocarcinoma. Approximately 10-15% of patients who undergo endoscopy for reflux symptoms have Barrett’s epithelium.
Cigarette smoking and chronic alcohol exposure are the most common aetiological factors for squamous cell carcinoma in Western cultures. However, no association has been found between alcohol and oesophageal adenocarcinoma. The risk of adenocarcinoma is also increased among smokers.
Achalasia, a condition that affects the oesophagus, increases the risk of both adeno and squamous cell carcinoma. However, dysphagia is not mentioned as a contributing factor.
Limited evidence suggests that excessive fruit and vegetable consumption may be protective against both types of cancer. Helicobacter pylori infection, which can cause stomach cancer, has not been associated with oesophageal cancer.
