You assess a 27-year-old female patient with a medical history of asthma. She is currently taking salbutamol 100 mcg 2 puffs as needed. However, she stopped taking her beclometasone dipropionate 400 mcg twice daily and salmeterol 50 mcg twice daily inhalers last week after discovering her pregnancy. She was worried about the potential harm to her unborn child. What would be the most suitable course of action?
Your Answer: Reassure + restart beclometasone and salmeterol inhalers
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 30-year-old male presents with a 3-month history of numbness in his right hand. During examination, you observe a loss of sensation in the palmar and dorsal regions of the 5th digit, while the sensation of the forearm remains intact. What is the probable diagnosis?
Your Answer: C8/T1 radiculopathy
Correct Answer: Cubital tunnel syndrome
Explanation:The correct answer is cubital tunnel syndrome. This condition is characterized by ulnar nerve neuropathy, which affects the sensory innervation of the palmar and dorsal aspects of 1.5 fingers medially. It can also cause wasting and paralysis of intrinsic hand muscles (except lateral two lumbricals) and the hypothenar muscles. To test for ulnar neuropathy, Froment’s test can be used to assess the function of the adductor pollicis muscle.
Axillary nerve neuropathy is not the correct answer. The axillary nerve has both motor and sensory functions, innervating the deltoid and teres minor muscles, as well as providing sensory innervation to the skin over the lower two-thirds of the posterior part of the deltoid and the long head of the triceps brachii.
C8/T1 radiculopathy is also not the correct answer. While it can mimic ulnar nerve neuropathy, the preserved sensation of the forearm would suggest cubital tunnel syndrome instead. The medial antebrachial cutaneous nerve (C8 and T1) provides sensation to the medial forearm, not the ulnar nerve.
Carpal tunnel syndrome is also not the correct answer. This condition is caused by median nerve dysfunction, resulting in sensory loss over the lateral 3.5 digits and loss of motor function to the flexor muscles of the forearm and hand, as well as those responsible for thumb movement.
The Ulnar Nerve: Overview, Branches, and Patterns of Damage
The ulnar nerve is a nerve that arises from the medial cord of the brachial plexus, specifically from the C8 and T1 spinal nerves. It provides motor innervation to several muscles in the hand, including the medial two lumbricals, adductor pollicis, interossei, hypothenar muscles (abductor digiti minimi, flexor digiti minimi), and flexor carpi ulnaris. It also provides sensory innervation to the medial 1 1/2 fingers on both the palmar and dorsal aspects.
The ulnar nerve travels through the posteromedial aspect of the upper arm before entering the palm of the hand via the Guyon’s canal, which is located superficial to the flexor retinaculum and lateral to the pisiform bone. The nerve has several branches, including the muscular branch, palmar cutaneous branch, dorsal cutaneous branch, superficial branch, and deep branch. These branches supply various muscles and skin areas in the hand.
Damage to the ulnar nerve can occur at the wrist or elbow. When damaged at the wrist, it can result in a claw hand deformity, which involves hyperextension of the metacarpophalangeal joints and flexion at the distal and proximal interphalangeal joints of the 4th and 5th digits. There may also be wasting and paralysis of intrinsic hand muscles (except lateral two lumbricals) and hypothenar muscles, as well as sensory loss to the medial 1 1/2 fingers. When damaged at the elbow, the same symptoms may occur, but with the addition of radial deviation of the wrist. It is important to note that in distal lesions, the clawing may be more severe, which is known as the ulnar paradox.

A 25-year-old woman visits her doctor complaining of diarrhoea and vomiting after spending Christmas with her family. Her sister has just informed her that she too is experiencing the same symptoms. The doctor suspects norovirus. What is the best way to prevent the spread of this virus?
Your Answer: Wash hands with soap and water
Explanation:Handwashing is more effective than alcohol gels in preventing the spread of norovirus.
Norovirus, also known as the winter vomiting bug, is a common cause of gastroenteritis in the UK. It is a type of RNA virus that can cause symptoms such as nausea, vomiting, and diarrhea, as well as headaches, low-grade fevers, and myalgia. The virus is highly contagious and can be transmitted through the fecal-oral route, as well as through aerosolized particles from vomit or contaminated bodily fluids. Good hand hygiene and isolation of infected individuals are important measures to limit transmission. Diagnosis is typically made through clinical history and stool culture viral PCR. While the infection is self-limiting in most cases, dehydration and electrolyte imbalances can occur and require supportive management.
Norovirus is a genus of non-encapsulated RNA virus species that can cause gastroenteritis. The CDC estimates that 1 in 5 cases of infectious gastroenteritis are caused by norovirus, with 685 million cases per year worldwide. Symptoms typically develop within 15-50 hours of infection and can include vomiting, diarrhea, headaches, low-grade fevers, and myalgia. The virus is highly contagious and can be transmitted through direct physical contact, contact with contaminated food, or through aerosolized particles from vomit or contaminated bodily fluids. Good hand hygiene and isolation of infected individuals are important measures to limit transmission. Diagnosis is typically made through clinical history and stool culture viral PCR. While the infection is self-limiting in most cases, dehydration and electrolyte imbalances can occur and require supportive management.

A 35-year-old man with a history of ulcerative colitis presents to the Emergency Department after experiencing fever and passing seven loose, bloody stools per day for the past 48 hours. The patient is diagnosed with a severe flare-up of ulcerative colitis. Additionally, he has a known anaphylactic allergy to aspirin. Considering his medical history, which medication should be approached with the most caution when treating this patient?
Your Answer: Sulfasalazine
Explanation: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 6-week-old baby is brought in by his first-time mother concerned about a flaky/scaly rash on his scalp.
Which of the following is the diagnosis?Your Answer: Seborrhoeic dermatitis
Explanation:Understanding Infantile Seborrhoeic Dermatitis (Cradle Cap)
Infantile seborrhoeic dermatitis, commonly known as cradle cap, is a condition that typically affects infants between the second week of life and the sixth month. It presents as a yellow scaly/flaky rash on the scalp, but can also affect other areas such as the ears, neck, face, and napkin area. While the condition is not harmful, it can be unsightly and uncomfortable for the infant.
Management of cradle cap involves simple measures such as regular washing of the scalp with baby shampoo, softening of scales with baby oil or soaking the crusts overnight with white petroleum jelly, then shampooing in the morning. If these measures are not effective, topical imidazole cream can be used.
It is important to note that cradle cap is not a fungal infection, eczema, erythema toxicum neonatorum (ETN), or scalp psoriasis. These conditions have different presentations and require different management strategies. Understanding the differences between these conditions can help parents and caregivers provide appropriate care for their infants.

You are evaluating a patient who is experiencing double vision. While gazing straight ahead, the patient's left eye deviates inward. When looking to the right, there is no apparent squint. However, when looking to the left, the patient cannot move the left eye outward, and double vision becomes more severe. What is the probable underlying issue?
Your Answer: Left 6th nerve palsy
Explanation:Understanding the 12 Cranial Nerves and their Functions
The human body has 12 pairs of cranial nerves that originate from the brainstem and control various functions such as movement, sensation, and reflexes. Each nerve has a specific function and pathway, and damage to any of these nerves can result in various clinical symptoms.
Some of the important functions of these nerves include smell (olfactory nerve), sight (optic nerve), eye movement (oculomotor, trochlear, and abducens nerves), facial sensation and mastication (trigeminal nerve), facial movement and taste (facial nerve), hearing and balance (vestibulocochlear nerve), taste and swallowing (glossopharyngeal nerve), phonation and innervation of viscera (vagus nerve), head and shoulder movement (accessory nerve), and tongue movement (hypoglossal nerve).
In addition to their primary functions, some of these nerves also play a role in various reflexes such as the corneal reflex, jaw jerk reflex, gag reflex, carotid sinus reflex, pupillary light reflex, and lacrimation reflex. Understanding the functions and pathways of these cranial nerves is essential for diagnosing and treating various neurological conditions.

As a foundation doctor on the postnatal ward, you conduct a newborn examination on a two-day-old baby girl. She was delivered normally and in good condition. During the hip examination, you observe that the left hip can be dislocated. What is the name of the examination you have conducted?
Your Answer: Barlow
Explanation:The Barlow manoeuvre is a technique used to try and dislocate a newborn’s femoral head. If successful, the Ortolani manoeuvre can then be used to relocate the dislocated femoral head. The Thomas test is not appropriate for neonates and is used to identify hip flexion contractures in older patients. The Denis Brown bar is an orthotic device used in conjunction with the Ponseti method to correct a fixed talipes.
Developmental dysplasia of the hip (DDH) is a condition that affects 1-3% of newborns and is more common in females, firstborn children, and those with a positive family history or breech presentation. It used to be called congenital dislocation of the hip (CDH). DDH is more often found in the left hip and can be bilateral in 20% of cases. Screening for DDH is recommended for infants with certain risk factors, and all infants are screened using the Barlow and Ortolani tests at the newborn and six-week baby check. Clinical examination includes testing for leg length symmetry, restricted hip abduction, and knee level when hips and knees are flexed. Ultrasound is used to confirm the diagnosis if clinically suspected, but x-ray is the first line investigation for infants over 4.5 months. Management includes the use of a Pavlik harness for children under 4-5 months and surgery for older children with unstable hips.

A 16-year-old female comes in for a follow-up. Three days ago she visited her physician with complaints of a severe sore throat, fatigue, and headache. The doctor prescribed amoxicillin to treat an upper respiratory tract infection. However, two days ago she developed a pruritic maculopapular rash that has spread throughout her body. Additionally, her initial symptoms have not improved. What is the probable diagnosis?
Your Answer: Infectious mononucleosis
Explanation:Patients with infectious mononucleosis should not be prescribed amoxicillin. Instead, supportive treatment is recommended for their care.
Understanding Infectious Mononucleosis
Infectious mononucleosis, also known as glandular fever, is a viral infection caused by the Epstein-Barr virus (EBV) in 90% of cases. It is most commonly seen in adolescents and young adults. The classic triad of symptoms includes sore throat, pyrexia, and lymphadenopathy, which are present in around 98% of patients. Other symptoms include malaise, anorexia, headache, palatal petechiae, splenomegaly, hepatitis, lymphocytosis, haemolytic anaemia, and a maculopapular rash. The symptoms typically resolve after 2-4 weeks.
The diagnosis of infectious mononucleosis is confirmed through a heterophil antibody test (Monospot test) in the second week of the illness. Management is supportive and includes rest, drinking plenty of fluids, avoiding alcohol, and taking simple analgesia for any aches or pains. It is recommended to avoid playing contact sports for 4 weeks after having glandular fever to reduce the risk of splenic rupture.
Interestingly, there is a correlation between EBV and socioeconomic groups. Lower socioeconomic groups have high rates of EBV seropositivity, having frequently acquired EBV in early childhood when the primary infection is often subclinical. However, higher socioeconomic groups show a higher incidence of infectious mononucleosis, as acquiring EBV in adolescence or early adulthood results in symptomatic disease.

A 12-month-old African-Caribbean boy is brought to see his General Practitioner by his mother with a 6-day history of fever, reduced feeding and increased irritability. His mother has also noticed this morning that his fingers and toes are swollen and tense and some of the skin is peeling. He is reluctant to play with toys or walk. On examination, he is pale, his lips are cracked and there are no rashes present. Ear, nose and throat (ENT) examinations reveal the presence of a red, swollen tongue he also has swollen, tender digits of his hands and feet.
He is admitted to hospital and his full blood count (FBC) result is shown below:
Investigation Result Normal value
Haemoglobin (Hb) 88 g/l 100–135 g/l
White cell count (WCC) 6.2 × 109/l 3.8–11 × 109/l
Platelets 150 × 109/l 150–400 × 1109/l
Mean corpuscular volume 93 fl 85–105 fl
Reticulocytes 6% 0.2–2%
Which of the following is the most likely diagnosis?
Your Answer: Sickle cell disease
Correct Answer: Kawasaki disease
Explanation:Kawasaki disease is a condition that causes inflammation in small and medium blood vessels, particularly in the coronary vessels. Children with this disease typically experience a high fever lasting more than five days, along with symptoms such as a strawberry tongue, dry cracked lips, rashes, peeling skin on the hands and feet, conjunctivitis, and swollen and painful hands and feet.
Acute lymphoblastic leukaemia (ALL) is a type of cancer that can cause bone pain and swelling in children, as well as unexplained fever, lethargy, recurrent infections, headaches, petechiae or purpura, and splenomegaly. However, a high white blood cell count would be present in ALL, which would be absent in this patient. Anaemia and thrombocytopenia are also common in ALL.
Nephrotic syndrome is a condition characterized by low levels of albumin and protein in the urine due to damage to the basement membrane of the renal glomerulus. Children with this condition typically experience swelling in the face, feet, abdomen, and genitals, but not in the fingers and toes as seen in this patient.
Rheumatic fever is a reaction to a bacterial infection, usually caused by group A streptococcus. Symptoms may include fever, abdominal pain, carditis, Sydenham’s chorea, and a rash, but joint pain typically affects the ankles, knees, elbows, and wrists rather than the hands and feet.
Sickle cell disease is an inherited condition that causes abnormal sickle-shaped red blood cells, leading to blockages in small blood vessels and chronic anemia. It is most common in Black African and Black Caribbean populations. Symptoms may include jaundice, anemia, and acute dactylitis, and screening is recommended for high-risk ethnic groups. A diagnosis of hemolysis is supported by a high reticulocyte count and normocytic anemia on FBC.

A 50-year-old man complains of vertigo and loss of hearing on the left side. Which test is most likely to suggest the presence of an acoustic neuroma?
Your Answer: Tongue deviated to the left
Correct Answer: Absent corneal reflex
Explanation:Consider acoustic neuroma if there is a loss of corneal reflex.
Understanding Vestibular Schwannoma (Acoustic Neuroma)
Vestibular schwannoma, also known as acoustic neuroma, is a type of brain tumor that accounts for 5% of intracranial tumors and 90% of cerebellopontine angle tumors. The condition is characterized by a combination of symptoms such as vertigo, hearing loss, tinnitus, and an absent corneal reflex. The affected cranial nerves can predict the features of the condition. For instance, cranial nerve VIII can cause vertigo, unilateral sensorineural hearing loss, and unilateral tinnitus. On the other hand, cranial nerve V can lead to an absent corneal reflex, while cranial nerve VII can cause facial palsy.
Bilateral vestibular schwannomas are often seen in neurofibromatosis type 2. The diagnosis of vestibular schwannoma is made through an MRI of the cerebellopontine angle, and audiometry is also important since only 5% of patients have a normal audiogram.
The management of vestibular schwannoma involves surgery, radiotherapy, or observation. The choice of treatment depends on the size and location of the tumor, the patient’s age and overall health, and the severity of symptoms. In conclusion, understanding vestibular schwannoma is crucial in managing the condition effectively.

A 42-year-old woman presented with complaints of constant fatigue and underwent blood tests. All results were within normal limits except for her thyroid function test (TFT) which revealed:
TSH 12.5 mU/l
Free T4 7.5 pmol/l
What would be the most suitable course of action?Your Answer: Levothyroxine
Explanation:The TFTs indicate a diagnosis of hypothyroidism, which can be treated with levothyroxine. Carbimazole is not suitable for this condition as it is used to treat hyperthyroidism. To ensure proper absorption, levothyroxine should be taken 30 minutes before consuming food, caffeine, or other medications.
Managing Hypothyroidism: Dosage, Monitoring, and Side-Effects
Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone. The main treatment for hypothyroidism is levothyroxine, a synthetic form of thyroid hormone. When managing hypothyroidism, it is important to consider the patient’s age, cardiac history, and initial starting dose. Elderly patients and those with ischaemic heart disease should start with a lower dose of 25mcg od, while other patients can start with 50-100mcg od. After a change in dosage, thyroid function tests should be checked after 8-12 weeks to ensure the therapeutic goal of normalising the thyroid stimulating hormone (TSH) level is achieved. The target TSH range is 0.5-2.5 mU/l.
Women with hypothyroidism who become pregnant should have their dose increased by at least 25-50 micrograms levothyroxine due to the increased demands of pregnancy. The TSH should be monitored carefully, aiming for a low-normal value. It is important to note that there is no evidence to support combination therapy with levothyroxine and liothyronine.
While levothyroxine is generally well-tolerated, there are some potential side-effects to be aware of. Over-treatment can lead to hyperthyroidism, while long-term use can reduce bone mineral density. In patients with cardiac disease, levothyroxine can worsen angina and lead to atrial fibrillation. It is also important to be aware of drug interactions, particularly with iron and calcium carbonate, which can reduce the absorption of levothyroxine. These medications should be given at least 4 hours apart.
In summary, managing hypothyroidism involves careful consideration of dosage, monitoring of TSH levels, and awareness of potential side-effects and drug interactions. With appropriate management, patients with hypothyroidism can achieve normal thyroid function and improve their overall health.

An 85-year-old man has just undergone an emergency repair for a ruptured abdominal aortic aneurysm. Preoperatively he was taking aspirin and warfarin; intraoperatively he received unfractionated heparin prior to application of the aortic cross-clamp. His observation findings are heart rate 120 bpm, BP 100/60 mmHg, respiratory rate 23/min, oxygen saturation 98% on air, temperature 38ºC. His blood results on admission to the critical care unit are as follows:
Hb 110 g/L
Male: (135-180)
Female: (115 - 160)
Platelets 30 * 109/L

(2-4 g/L)
PT 20 seconds
(10-12 seconds)
APTT 60 seconds
(35-45 seconds)
FDP 60 ug/mL
(<10 ug/mL)
What is the most likely explanation for the blood abnormalities seen in this case?Your Answer: Disseminated intravascular coagulation
Explanation:The most likely diagnosis for the patient’s deranged vital signs after a major operation and suspected sepsis is disseminated intravascular coagulation (DIC). This is characterized by low platelets, increased clotting time, and raised fibrin degradation products (FDPs). DIC is often caused by the release of tissue factor (TF) in response to cytokines, tumor necrosis factor, and endotoxin. Anastomotic leak, heparin-induced thrombocytopenia, warfarin use, and aspirin use are unlikely causes based on the patient’s history and blood results.
Understanding Disseminated Intravascular Coagulation (DIC) Diagnosis
Under normal conditions, coagulation and fibrinolysis work together to maintain homeostasis. However, in DIC, these processes become dysregulated, leading to widespread clotting and bleeding. One key factor in the development of DIC is the release of tissue factor (TF), a glycoprotein found on the surface of various cell types. Normally, TF is not in contact with the general circulation, but it is exposed after vascular damage or in response to certain cytokines. Once activated, TF triggers the extrinsic pathway of coagulation, which then triggers the intrinsic pathway. DIC can be caused by various factors, including sepsis, trauma, obstetric complications, and malignancy.
To diagnose DIC, a typical blood picture will show decreased platelets and fibrinogen, increased fibrinogen degradation products, and the presence of schistocytes due to microangiopathic hemolytic anemia. Additionally, both the prothrombin time and activated partial thromboplastin time are prolonged, while bleeding time and platelet count are often low. Understanding the diagnosis of DIC is crucial for prompt and effective treatment.

A 31-year-old pilot comes in for his yearly physical examination. He has no significant medical history, does not take any regular medication, and reports no concerning symptoms. He maintains a healthy lifestyle and enjoys participating in ultramarathons as a runner.
During the physical examination, an ECG is conducted, which was normal during his last check-up the previous year. What would be the most worrisome ECG characteristic?Your Answer: J-wave
Correct Answer: Left bundle branch block (LBBB)
Explanation:A new left bundle branch block on an ECG is always a sign of pathology and not a normal variant. It indicates a delay in the left half of the conducting system, which can be caused by conditions such as aortic stenosis, cardiomyopathy, or ischaemia. However, other findings on an ECG, such as J-waves, left axis deviation, second-degree heart block (Mobitz I), or a short QT interval, may be normal variants in a healthy individual and not a cause for concern unless accompanied by symptoms of arrhythmias.
Left Bundle Branch Block: Causes and Diagnosis
Left bundle branch block (LBBB) is a cardiac condition that can be diagnosed through an electrocardiogram (ECG). The ECG shows typical features of LBBB, including a ‘W’ in V1 and a ‘M’ in V6. It is important to note that new LBBB is always pathological and can be caused by various factors such as myocardial infarction, hypertension, aortic stenosis, and cardiomyopathy. However, diagnosing a myocardial infarction for patients with existing LBBB can be difficult. In such cases, the Sgarbossa criteria can be used to aid in diagnosis.
Other rare causes of LBBB include idiopathic fibrosis, digoxin toxicity, and hyperkalaemia. It is crucial to identify the underlying cause of LBBB to determine the appropriate treatment plan. Therefore, patients with LBBB should undergo further evaluation and testing to determine the cause of their condition. By identifying the cause of LBBB, healthcare professionals can provide appropriate treatment and management to improve the patient’s overall health and well-being.

A mother brings in her 4-year-old daughter to the GP surgery. For the past 3 weeks, the girl has been experiencing discomfort while passing urine. She has a history of 3 previous urinary tract infections. During external examination, you notice thin semitranslucent adhesions that cover the vaginal opening between the labia minora but not the urethra opening. You prescribe a course of trimethoprim. What other treatment options would you consider initiating?
Your Answer: Oestrogen cream
Explanation:Labial adhesions are typically caused by low levels of estrogen and are usually treated conservatively as they often resolve during puberty. However, if there are recurrent urinary tract infections, oestrogen creams may be considered as a treatment option. The use of trimethoprim pessary, IV dexamethasone, and oral prednisolone are not appropriate treatments for labial adhesions. It is important to address the adhesion as leaving it untreated can lead to complications.
Labial Adhesions: A Common Condition in Young Girls
Labial adhesions refer to the fusion of the labia minora in the middle, which is commonly observed in girls aged between 3 months and 3 years. This condition can be treated conservatively, and spontaneous resolution usually occurs around puberty. It is important to note that labial adhesions are different from an imperforate hymen.
Symptoms of labial adhesions include problems with urination, such as pooling in the vagina. Upon examination, thin semitranslucent adhesions covering the vaginal opening between the labia minora may be seen, which can sometimes cover the vaginal opening completely.
Conservative management is typically appropriate for most cases of labial adhesions. However, if there are associated problems such as recurrent urinary tract infections, oestrogen cream may be tried. If this fails, surgical intervention may be necessary.
In summary, labial adhesions are a common condition in young girls that can be managed conservatively. It is important to seek medical attention if symptoms persist or worsen.

Which of the following is not a known side effect of the combined oral contraceptive pill?
Your Answer: Increased risk of cervical cancer
Correct Answer: Increased risk of ovarian cancer
Explanation:While the combined oral contraceptive pill may increase the risk of breast and cervical cancer, it has been found to provide protection against ovarian and endometrial cancer. In fact, studies have shown that the pill can actually decrease the risk of ovarian cancer.
Pros and Cons of the Combined Oral Contraceptive Pill
The combined oral contraceptive pill is a highly effective method of birth control with a failure rate of less than 1 per 100 woman years. It does not interfere with sexual activity and its contraceptive effects are reversible upon stopping. Additionally, it can make periods regular, lighter, and less painful, and may reduce the risk of ovarian, endometrial, and colorectal cancer. It may also protect against pelvic inflammatory disease, ovarian cysts, benign breast disease, and acne vulgaris.
However, there are also some disadvantages to the combined oral contraceptive pill. One of the main issues is that people may forget to take it, which can reduce its effectiveness. It also offers no protection against sexually transmitted infections. There is an increased risk of venous thromboembolic disease, breast and cervical cancer, stroke, and ischaemic heart disease, especially in smokers. Temporary side-effects such as headache, nausea, and breast tenderness may also be experienced.
It is important to weigh the pros and cons of the combined oral contraceptive pill before deciding if it is the right method of birth control for you. While some users report weight gain while taking the pill, a Cochrane review did not support a causal relationship. Overall, the combined oral contraceptive pill can be an effective and convenient method of birth control, but it is important to discuss any concerns or potential risks with a healthcare provider.

A 65-year-old woman comes in with a tremor. What distinguishing characteristic would indicate a diagnosis of essential tremor instead of Parkinson's disease?
Your Answer: Tremor is worse when the arms are outstretched
Explanation:Typical symptoms of Parkinson’s include bradykinesia, postural instability, and initially unilateral symptoms. On the other hand, alcohol can alleviate essential tremor symptoms.
Understanding Essential Tremor
Essential tremor, also known as benign essential tremor, is a genetic condition that typically affects both upper limbs. The most common symptom is a postural tremor, which worsens when the arms are outstretched. However, the tremor can be improved by rest and alcohol consumption. Essential tremor is also the leading cause of head tremors, known as titubation.
When it comes to managing essential tremor, the first-line treatment is propranolol. This medication can help reduce the severity of the tremors. In some cases, primidone may also be used to manage the condition. It’s important to note that essential tremor is a lifelong condition, but with proper management, individuals can lead a normal life. By understanding the symptoms and treatment options, those with essential tremor can take control of their condition and improve their quality of life.

Which of the following statements best describes bladder cancer?
Your Answer: Survival correlates well with TNM staging at diagnosis.
Explanation:Bladder Cancer: Prognostic Factors, Staging, and Treatment Options
Bladder cancer is a common malignancy that affects the urinary system. Survival rates are closely linked to the TNM staging at diagnosis, with non-muscle invasive bladder cancer having a good prognosis and decreasing survival rates with increasing stage. The most significant prognostic factors for bladder cancer are grade, depth of invasion, and the presence of carcinoma in situ. Chemotherapy for metastatic disease is seldom used and has limited effectiveness. Cisplatin-based chemotherapy regimens are the standard treatment for metastatic bladder cancer, with a median overall patient survival of 13-15 months and a 2-year survival rate of 15-20%. Careful follow-up is necessary for non-muscle invasive bladder cancer due to the high rate of disease recurrence and progression.

Upon examination, there is a small, smooth, nontender, mobile lump. The skin overlying the lump appears normal in color and temperature. The lump does not move on swallowing or tongue protrusion, and the skin cannot be moved over the top of the lump. What is the most likely diagnosis?Your Answer: Lipoma
Correct Answer: Sebaceous cyst
Explanation:Differentiating between lumps and bumps: A guide to common masses
When it comes to lumps and bumps on the body, it can be difficult to determine what they are and whether they require medical attention. Here are some common types of masses and their characteristics to help differentiate between them:
Sebaceous cysts: These small, smooth lumps are caused by a blocked hair follicle and have a central punctum. They are attached to the skin and may develop a horn. If infected, they can become tender and erythematous.
Lipomas: These deep masses are typically soft, doughy, and mobile. An ultrasound or biopsy may be needed to rule out sarcoma or liposarcoma.
Sternocleidomastoid tumors: This congenital lump appears within the first few weeks of life and is located beneath the sternocleidomastoid muscle. It restricts contralateral head movement.
Thyroid carcinoma: A hard, firm, non-tender mass close to the midline that moves up with swallowing may indicate thyroid cancer.
Thyroid goitre: A smooth or multi-nodular enlargement close to the midline that moves up with swallowing may indicate a thyroid goitre. Symptoms associated with thyroid diseases may also be present.
Knowing the characteristics of these common masses can help individuals determine when to seek medical attention.

Question 19
Correct

A 75-year-old man has been hospitalized with abdominal discomfort. The surgical team intends to conduct a contrast-enhanced CT scan, but they are apprehensive due to his stage 3 chronic kidney disease. Below is his most recent renal function:
Na+ 142 mmol/l
K+ 4.6 mmol/l
Urea 8.1 mmol/l
Creatinine 130 µmol/l
What is the most crucial measure in decreasing the risk of contrast-induced nephropathy?Your Answer: Intravenous 0.9% sodium chloride pre- and post-procedure
Explanation:Contrast Media Nephrotoxicity and Prevention
Contrast media nephrotoxicity is a condition where there is a 25% increase in creatinine within three days of intravascular administration of contrast media. This condition usually occurs 2-5 days after administration and is caused by various risk factors such as known renal impairment, dehydration, cardiac failure, and the use of nephrotoxic drugs. Procedures such as CT with contrast and coronary angiography/percutaneous coronary intervention (PCI) are examples that may cause contrast-induced nephropathy.
To prevent contrast-induced nephropathy, intravenous 0.9% sodium chloride at a rate of 1 mL/kg/hour for 12 hours pre- and post-procedure is recommended. Isotonic sodium bicarbonate is also supported by evidence. However, N-acetylcysteine, which was previously given, is now considered ineffective. Patients who are high-risk for contrast-induced nephropathy should have metformin withheld for at least 48 hours and until their renal function has been shown to be normal to avoid the risk of lactic acidosis.
In summary, contrast media nephrotoxicity is a condition that can occur after the administration of contrast media. It is caused by various risk factors and can be prevented by using intravenous sodium chloride or isotonic sodium bicarbonate. N-acetylcysteine is no longer recommended, and patients at high risk should have metformin withheld until their renal function is normal.

Question 20
Correct
-
A 58-year-old woman presents to the emergency department with a 1-day history of facial paralysis. She also complains of some mild ear pain over the last 2 days. On examination, she has a fixed half-smile on the left side of her face. She is unable to raise her left eyelid and has increased sensitivity to sound in her left ear. She denies dizziness or vertigo. The remainder of her cranial nerve examination is normal. ENT examination shows an erythematous left ear canal and vesicles over her soft palate.
What is the most appropriate treatment to initiate for the likely diagnosis?Your Answer: Oral aciclovir and prednisolone
Explanation:When a patient presents with a facial nerve palsy and a vesicular rash, Ramsay Hunt syndrome should be considered. The vesicles may not be limited to the ear canal and can also appear on the tongue or soft palate. Treatment typically involves administering oral aciclovir and corticosteroids, unless the patient is severely ill. Ganciclovir is used to treat cytomegalovirus, while amoxicillin would be a more suitable option if bacterial otitis media was the underlying cause of the patient’s symptoms.
Understanding Ramsay Hunt Syndrome
Ramsay Hunt syndrome, also known as herpes zoster oticus, is a condition that occurs when the varicella zoster virus reactivates in the geniculate ganglion of the seventh cranial nerve. The first symptom of this condition is often auricular pain, followed by facial nerve palsy and a vesicular rash around the ear. Other symptoms may include vertigo and tinnitus.
To manage Ramsay Hunt syndrome, doctors typically prescribe oral aciclovir and corticosteroids. These medications can help reduce the severity of symptoms and prevent complications.
