A 25-year-old woman presents to the clinic with nausea, thirst and dehydration. She mentioned that she has an uncle with previous parathyroid gland excision and a cousin who has recently been diagnosed with insulinoma. On examination, her BP is 135/72 mmHg, her pulse is 70/min and regular, her BMI is 20. Cardiovascular, respiratory and abdominal examinations are unremarkable. Investigations show: Hb 12.6 g/dL, WCC 5.4 x109/L, PLT 299 x109/L, Na+ 139 mmol/L, K+ 4.4 mmol/L, Creatinine 121 ىmol/L, Albumin 37 g/l, Ca++ 2.95 mmol/L, PTH 18 (normal<10). Which of the following is the most likely cause of her raised calcium?
Your Answer: Parathyroid adenoma
Correct Answer: Parathyroid hyperplasia
Explanation:The combination of Insulinoma and Parathyroid diseases is suggestive of MEN 1 syndrome.
Multiple endocrine neoplasia type 1 (MEN1) is a rare hereditary tumour syndrome inherited in an autosomal dominant manner and characterized by a predisposition to a multitude of endocrine neoplasms primarily of parathyroid, entero-pancreatic, and anterior pituitary origin, as well as non-endocrine neoplasms.
Other endocrine tumours in MEN1 include foregut carcinoid tumours, adrenocortical tumours, and rarely pheochromocytoma. Nonendocrine manifestations include meningiomas and ependymomas, lipomas, angiofibromas, collagenomas, and leiomyomas.Primary hyperparathyroidism (PHPT), due to parathyroid hyperplasia is the most frequent and usually the earliest expression of MEN-1, with a typical age of onset at 20–25 years.

A 50-year-old woman came to the diabetes clinic for her regular follow up. The following results are obtained: Urine analysis: Protein+, HBA1c 86mmol/mol (10.0%). What is her average blood glucose level during the past 2 months?
Your Answer: There is no relation between HbA1c and average blood glucose
Correct Answer: 15
Explanation:The level of haemoglobin A1c (HbA1c), also known as glycated haemoglobin, determines how well a patient’s blood glucose level has been controlled over the previous 8–12 weeks. Recent studies have been made to correlate between HbA1c and average glucose level.
Using the following formula: Average blood glucose (mmol/l) = (1.98 x 1 HbA1c) – 4.29 -

A 70-year-old female presented to her ophthalmologist with a complaint of weakening eyesight despite continued use of her corrective glasses. She also had a history of mild headaches for a few weeks. On fundoscopy, the disc had blurred margins with mild cupping and a sickle shaped scotoma in both eyes. What is the most appropriate treatment in this case?
Your Answer: Scleral buckling
Correct Answer: Pilocarpine eye drops
Explanation:Frequent change of eye glasses, scotoma, and mild cupping are suggestive of primary open angle glaucoma. This means that the anterior angle of the eye is normal but there is a problem in the trabecular meshwork, where the Schlemm’s Canal is not allowing the drainage of the aqueous humor. Pilocarpine should be given to the patient because it is a parasympathomimetic agent. It causes the ciliary muscle of the eye to contract, causing the trabecular meshwork to open up, allowing the aqueous humor to drain again.

Choose the correct definition regarding the standard error of the mean:
Your Answer: Square root (Standard deviation / number of patients)
Correct Answer: Standard deviation / square root (number of patients)
Explanation:The SEM is an indicator of how close the sample mean is to the population mean. In reality, however, only one sample is extracted from the population. Therefore, the SEM is estimated using the standard deviation (SD) and a sample size (Estimated SEM). The SEM computed by a statistical program is an estimated value calculated via this process.

A 60 yr. old man presented with severe central chest pain for the last 2 hours. He was on insulin for diabetes mellitus and he was dependent on haemodialysis because of end stage renal failure. He had undergone haemodialysis 48 hours prior to this presentation. His ECG showed an acute inferior myocardial infarction. Despite thrombolysis and other appropriate treatment, he continued to have chest pain after 6 hours from the initial presentation. His blood pressure was 88/54 mmHg and he had bibasal crepitations. His investigation results are given below. Serum sodium 140 mmol/l (137-144), Serum potassium 6.6 mmol/l (3.5-4.9), Serum urea 50 mmol/l (2.5-7.5), Serum creatinine 940 μmol/l (60-110), Haemoglobin 10.2g/dl (13.0-18.0), Troponin T >24 g/l (<0.04), Left ventricular ejection fraction was 20%. What is the most appropriate management for this patient?
Your Answer: Haemodialysis
Correct Answer: Coronary angiography and rescue PCI
Explanation:According to the history the patient has cardiogenic shock and pulmonary oedema. On-going ischaemia is indicated by persisting symptoms. So the most appropriate management is coronary angiography and rescue PCI. There are no indications for blood transfusion at this moment and it will aggravate the pulmonary oedema. Haemodialysis, beta blockers and furosemide cannot be given due to low blood pressure.

Among the following which is the beneficial effect of nitro-glycerine?
Your Answer: Increase of left ventricular preload
Correct Answer: Dilation of systemic veins
Explanation:Dilation of systemic veins is a beneficial effect of nitro-glycerine.
Administration of nitro-glycerine results in the dilation of systemic veins and decrease of myocardial wall tension and oxygen demand. Dilatation of systemic veins can cause reduced systemic vascular resistance leading to reduced cardiac workload thus reducing anginal symptoms secondary to demand ischemia.
This is accompanied by vasodilation of large and medium-sized coronary arteries with increased coronary blood flow to the sub endocardium.

A 11-year-old boy has a history of tonsillitis followed by haematuria and hypertension about 10 days later. What would be the characteristic blood test finding in this condition?
Your Answer: Increased cryoglobulins
Correct Answer: Depressed CH 50 level
Explanation:Because the medical history included tonsillitis followed by haematuria and hypertension, there is a strong suspicion of a case of post-streptococcal glomerulonephritis (PSGN). Patients with PSGN usually have serological findings showing depressed serum haemolytic component CH50 and serum concentrations of C3. Sometimes depressed C4 levels are also apparent, but not always, therefore, the answer to this question is: depressed CH50 level.

A 45 year old man, known case of hypothyroidism, presents with a 3 month history of pain and stiffness in the joints of his hands and feet. He also complains of dyspnoea occurring for the past 6 weeks. On examination there is a right pleural effusion and swollen hand joints. The clinician makes a diagnosis of rheumatoid arthritis. Which of the following is most characteristic of a rheumatoid pleural effusion?
Your Answer: It is a transudate
Correct Answer: It has a low glucose level
Explanation:The typical “rheumatoid effusion” is a sterile exudative fluid with low pH (<7.3), low glucose (<60 mg. dL−1) and elevated lactate dehydrogenase (may be >700 IU). It should initially be treated with NSAIDs. Decortication should be reserved in patients with thickened pleura who have symptomatic dyspnoea.

The average weight of 64 patients with type 2 diabetes mellitus was 81 kg, with a standard deviation of 12 kg. What is the standard error of the mean?
Your Answer: Square root (64 / 12)
Correct Answer: 1.5
Explanation:The SEM is dependent on the variation in the population and the number of the extracted samples. A large variation in the population causes a large difference in the sample means, ultimately resulting in a larger SEM. However, as more samples are extracted from the population, the sample means move closer to the population mean, which results in a smaller SEM. In short, the SEM is an indicator of how close the sample mean is to the population mean. Standard error of the mean = standard deviation / square root (number of patients)
The standard error of the mean is calculated by the standard deviation / square root (number of patients)= 12 / square root (64) = 12 / 8 = 1.5

A 27-year-old realtor presented with progressive weakness of both legs over the last 3 years. He complained of being unable to see well at night and having an impaired sense of smell. On examination he had a shortened fourth toe bilaterally with pes cavus. Neurological examination revealed a loss of pinprick sensation to bilateral knees, and weakness of both legs that was more prominent distally. Which of the following would be the best blood test to order to make a diagnosis?
Your Answer: ANCA
Correct Answer: Phytanic acid
Explanation:The diagnosis is Refsum’s disease. This is an autosomal recessive disorder that causes a sensorimotor peripheral neuropathy. It is caused by defective alpha oxidation of phytanic acid leading to its accumulation in tissues. Cardiac conduction abnormalities and cardiomyopathies may also occur.
Epiphyseal dysplasia causes a characteristic shortening of the fourth toe. Serum phytanic acid levels are elevated. Treatment is by dietary restriction of foods containing phytanic acid (dairy products, fish, beef and lamb). -

A 44-year-old hairdresser with a history of myasthenia gravis is admitted to the Emergency Department. She is currently taking pyridostigmine, but there has been a significant worsening of her symptoms following antibiotic treatment for a chest infection. On examination she is dyspnoeic and cyanotic with quiet breath sounds in both lungs. Other than respiratory support, what are the two other treatments of choice?
Your Answer: Plasmapheresis or intravenous immunoglobulins
Explanation:This patient is having a myasthenic crisis. Opinions vary as to whether plasmapheresis or intravenous immunoglobulins should be given first-line. Plasmapheresis usually works much faster, but is more costly due to equipment.
Myasthenia gravis is an autoimmune disorder resulting in insufficient functioning acetylcholine receptors. Antibodies to acetylcholine receptors are seen in 85-90% of cases. Myasthenia gravis is more common in women (2:1). -

A baby is born to a mother who is known to have chronic hepatitis B. The mothers latest results are as follows: HBsAg: Positive, HBeAg: Positive. What is the most appropriate strategy for reducing the vertical transmission rate?
Your Answer: Give the newborn hepatitis B immunoglobulin
Correct Answer: Give the newborn hepatitis B vaccine + hepatitis B immunoglobulin
Explanation:The Green Book guidelines report in an active infection (HBeAg+ and HBsAg+) to give the vaccine as well as immunoglobulin. If antibodies are present it is not active infection (anti-Hbe) and then in that case only the vaccine, and no immunoglobulin, would be given. The presence of HBeAg means a person is infectious and can transmit to other people.

A 52 yr. old female who was a smoker, with a history of asymptomatic atrial septal defect (ASD) presented with difficulty in breathing on exertion and ankle oedema for the past 2 weeks. She has defaulted on her follow up for ASD. On examination she was cyanosed and clubbing was noted. Her pulse rate was 92 and blood pressure was 100/60 mmHg. Echocardiography revealed a dilated right ventricle of the heart. The right ventricular pressure was 90 mmHg. Significant tricuspid and pulmonary regurgitation were also noted. Which of the following is the most probable diagnosis?
Your Answer: Cor pulmonale
Correct Answer: Eisenmenger’s syndrome
Explanation:According to echocardiography findings pulmonary pressure is closer to systemic blood pressure and it is evidence of pulmonary hypertension. Because of the reversal of shunt due to pulmonary hypertension, cyanosis and clubbing have developed. So the most probable diagnosis is Eisenmenger’s syndrome.

Empagliflozin was found to reduce the risk of cardiovascular deaths, non-fatal myocardial infarction and non-fatal stroke when added to standard treatment plans in patients with type 2 diabetes mellitus. This information was shared in 2015 by The New England Journal of Medicine and the results were expressed per 1000 patient years. In fact, empagliflozin had an event rate of 37.3/1000 patient years and placebo an event rate of 43.9/1000 patient years. How many patients who are at high cardiovascular risk need to be treated with empagliflozin to prevent a cardiovascular death, a non-fatal myocardial infarction or a non-fatal stroke?
Your Answer: 1000
Correct Answer: 150
Explanation:The number needed to treat (NNT) is an absolute effect measure that has been used to assess beneficial and harmful effects of medical interventions. In this case the NNT can be calculated as follows: NNT = 1/ Absolute risk reduction (ARR). ARR=(Control event rate expressed per 1000 patient years) – (Experimental event rate expressed per 1000 patient years) = 43.9-37.3 = 6.6/1000 patient years
NNT=(Patient years)/ARR = 1000/ 6.6 = 151.5. The closest to 151.5 is 150, thus it is the correct answer.

A 40-year-old man is referred by his general practitioner. He has a family history of premature cardiovascular disease. Cholesterol testing reveals triglyceride levels of 4.2 mmol/l and a high-density lipoprotein (HDL) level of 0.8 mmol/l. You advise him to start fibrate therapy. Which of the following best describes the mode of action for fibrates?
Your Answer: They are inhibitors of lipoprotein lipase activity and increase HDL synthesis
Explanation:Treatment with fibrates, a widely used class of lipid-modifying agents, results in a substantial decrease in plasma triglycerides and is usually associated with a moderate decrease in LDL cholesterol and an increase in HDL cholesterol concentrations.
Evidence from studies is available to implicate 5 major mechanisms underlying the above-mentioned modulation of lipoprotein phenotypes by fibrates:
1. Induction of lipoprotein lipolysis.
2. Induction of hepatic fatty acid (FA) uptake and reduction of hepatic triglyceride production.
3. Increased removal of LDL particles. Fibrate treatment results in the formation of LDL with a higher affinity for the LDL receptor, which is thus catabolized more rapidly.
4. Reduction in neutral lipid (cholesteryl ester and triglyceride) exchange between VLDL and HDL may result from decreased plasma levels of TRL.
5. Increase in HDL production and stimulation of reverse cholesterol transport. Fibrates increase the production of apoA-I and apoA-II in the liver, which may contribute to the increase of plasma HDL concentrations and a more efficient reverse cholesterol transport. -

A 21-year-old female presents to the emergency department having taken an overdose of 40 x 500mg paracetamol tablets and 400ml of vodka. This is her fourth attendance with an overdose over the past 3 years. She is also known to the local police after an episode of reckless driving/road rage. On arrival, she is tearful and upset. Vital signs and general physical examination are normal apart from evidence of cutting on her arms. She is given activated charcoal. Which of the following is the most likely diagnosis?
Your Answer: Endogenous depression
Correct Answer: Borderline personality disorder
Explanation:The given clinical scenario is highly suggestive of a borderline personality disorder.
Borderline personality disorder is marked out by instability in moods, behaviour, and relationships. The diagnosis is confirmed by the presence of at least 5 of the following symptoms;
1) Extreme reactions including panic, depression, rage, or frantic actions to abandonment, whether real or perceived
2) A pattern of intense and stormy relationships with family, friends, and loved ones, often veering from extreme closeness and love to extreme dislike or anger
3) Distorted and unstable self-image or sense of self, which can result in sudden changes in feelings, opinions, values, or plans and goals for the future (such as school or career choices)
4) Impulsive and often dangerous behaviours, such as spending sprees, unsafe sex, substance abuse, reckless driving, and binge eating
5) Recurring suicidal behaviours or threats or self-harming behaviour, such as cutting, intense and highly changeable moods, with each episode lasting from a few hours to a few days
6) Chronic feelings of emptiness and/or boredom
7) Inappropriate, intense anger or problems controlling anger
8) Having stress-related paranoid thoughts or severe dissociative symptoms, such as feeling cut off from oneself, observing oneself from outside the body, or losing touch with reality.Other options:
There are no features consistent with endogenous depression, such as early morning wakening or loss of appetite.
There are also no features consistent with hypomania such as pressure of speech, a flight of ideas, or over-exuberant behaviour.
The lack of history of drug abuse rules out drug-induced psychosis.
An anti-social personality disorder is characterized by a failure to conform to social norms and repeated lawbreaking. There is consistent irresponsibility, impulsivity, and disregard for both their safety and that of others. This is not the case in the given scenario. -

A study is carried out to assess the efficacy of a new anti-epileptic drug for children with absence seizures. The total number of the children selected for the study was 400, from which 150 children were assigned to take the new drug and 250 children were assigned in the control group. After a period of four months, only 15 children taking the new drug had a seizure compared to 100 children from the control group who had seizure. What is the correct value regarding the relative risk reduction?
Your Answer: 3.33
Correct Answer: 75%
Explanation:Relative risk reduction (RRR) tells you by how much the treatment reduced the risk of bad outcomes relative to the control group who did not have the treatment. In the previous example, the relative risk reduction of fever and rash in the group of the children on the intervention was 40 per cent (1 – 0.6 = 0.4 or 40 per cent). RRR = (EER -CER) / CER = (0.1 – 0.4) / 0.4 = -0.75 or 75% reduction.

Which of the following features is characteristic of acute intermittent porphyria?
Your Answer: Increased urinary porphobilinogen between acute attacks
Explanation:Urinary porphobilinogen is increased between attacks of acute intermittent porphyria (AIP) and even more so, between acute attacks.
AIP is a rare autosomal dominant condition caused by a defect in porphobilinogen deaminase, an enzyme involved in the biosynthesis of haem. This results in the toxic accumulation of delta-aminolaevulinic acid and porphobilinogen.
Abdominal and neuropsychiatric symptoms are characteristic of AIP especially in people between the ages of 20–40 years. The disease is more common in females than in males (5:1). Major signs and symptoms of AIP include abdominal pain, vomiting, motor neuropathy, hypertension, tachycardia, and depression.
Diagnosis:
1. Urine turns deep red on standing (classical picture of AIP)
2. Raised urinary porphobilinogen (elevated between attacks and to a greater extent, between acute attacks)
3. Raised serum levels of delta-aminolaevulinic acid and porphobilinogen
4. Assay of red blood cells for porphobilinogen deaminase -
