A 57 year old, alcoholic male was admitted to the medical ward for an ascitic tap. The ascitic fluid was found to be yellow in colour. Which of the following had most likely lead to this observation?
Your Answer:
Correct Answer: Decompensated cirrhosis
Explanation:Uncomplicated cirrhotic ascites is usually translucent. If the patient is deeply jaundiced, the fluid might appear yellow/brown.
Turbidity or cloudiness of the ascites fluid suggests that infection is present and further diagnostic testing should be performed.
Pink or bloody fluid is most often caused by mild trauma, with subcutaneous blood contaminating the sample.
Bloody ascites is also associated with hepatocellular carcinoma or any malignancy-associated ascites.
Milky-appearing fluid usually has an elevated triglyceride concentration. Such fluid, commonly referred to as chylous ascites, can be related to thoracic duct injury or obstruction or lymphoma, but it is often related primarily to cirrhosis. -

1. Increased production of uric acid – Purine rich diet, Tumour lysis syndrome, HGPRT deficiency (Lesch-Nyhan and Kelley-Seegmiller syndromes), Increased PRPP synthetase activity and Polycythaemia
2. Decreased excretion of uric acid – Renal impairment, Metabolic syndrome, Drugs (diuretics, low-dose aspirin, cyclosporin, tacrolimus, pyrazinamide, ethambutol, levodopa, nicotinic acid), Acidosis, Pre-eclampsia and eclampsia, Hypothyroidism and hyperparathyroidism, Sarcoidosis, Familial juvenile gouty nephropathy, Chronic lead intoxication, Trisomy 21

A 54 year old man presents to the physician complaining of chest pain and fever. He underwent hemicolectomy a few days back. Echocardiography is done which shows a systolic murmur. Which other investigation would be required?
Your Answer:
Correct Answer: Blood culture
Explanation:Infective endocarditis (IE) is an infectious inflammation of the endocardium that affects the heart valves. The condition is a result of bacteraemia, which is most commonly caused by dental procedures, surgery, distant primary infections, and nonsterile injections. IE clinically presents with either an acute or subacute course. Acute disease is usually caused by Staphylococcus aureus and causes rapid endocardium destruction. Subacute progression is most commonly caused by viridans streptococci species and generally affects individuals with pre-existing damage to the heart valves, structural heart defects, or the presence of prosthetic valves. Clinical features include constitutional symptoms (fatigue, fever/chills, malaise) in combination with signs of pathological cardiac changes (e.g., new or changed heart murmur, heart failure signs) and possibly manifestations of subsequent damage to other organs (e.g., glomerulonephritis, septic embolic stroke). Diagnosis is made based on the Duke criteria, whose main features include positive blood cultures and evidence of endocardial involvement in echocardiography. Initial treatment of IE consists of empiric IV antibiotic therapy, which is then adapted to blood culture results and continued for four to six weeks. Prophylaxis is only administered in specific circumstances, e.g., in patients with pre-existing heart conditions undergoing dental or surgical procedures. If left untreated, infective endocarditis can be fatal within a few weeks.

Question 8
Incorrect

A 42 year old female with a history of SLE presents with an exacerbation of wrist pain. Which of the following markers would be the most suitable for monitoring disease activity?
Your Answer:
Correct Answer: Anti-dsDNA titres
Explanation:A high level of anti-dsDNA in the blood is strongly associated with lupus and is often significantly increased during or just prior to a flare-up. When the anti-dsDNA is positive and the person tested has other clinical signs and symptoms associated with lupus, it means that the person tested likely has lupus. This is especially true if an anti-Sm test is also positive.
In the evaluation of someone with lupus nephritis, a high level (titre) of anti-dsDNA is generally associated with ongoing inflammation and damage to the kidneys.
A very low level of anti-dsDNA is considered negative but does not exclude a diagnosis of lupus. Only about 65-85% of those with lupus will have anti-dsDNA.
Low to moderate levels of the autoantibody may be seen with other autoimmune disorders, such as Sjögren syndrome and mixed connective tissue disease (MCTD).

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:
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.

Rash and arthralgias are classic presentations. Pleurisy can be present as pulmonary involvement may occur with DILE.

Which of the following does the inferior mesenteric artery supply?
Your Answer:
Correct Answer: From the splenic flexure to the first third of the rectum
Explanation:The coeliac axis supplies the liver and stomach and from the oesophagus to the first half of the duodenum.
The second half of the duodenum to the first two thirds of the transverse colon is supplied by the superior mesenteric artery.
The inferior mesenteric supplies the last third of the transverse colon (approximately from the splenic flexure) to the first third of the rectum.
The last two thirds of the rectum are supplied by the middle rectal artery.
The greater curvature of the stomach is supplied by branches of the splenic artery, which itself comes from the coeliac axis. -

A 30 year old female with type I diabetes for 13 years, came for pre-pregnancy counselling. Which of the following is the most suitable advise for her?
Your Answer:
Correct Answer: She should aim to have a pre-pregnancy HbA1c of <48 mmol/mol (6.5%)
Explanation:According to NICE guidelines women with type I diabetes, who are expecting a child should aim to keep their HbA1c level[1] below 48 mmol/mol (6.5%) without causing problematic hypoglycaemia. Women with diabetes whose HbA1c level is above 86 mmol/mol (10%) should be strongly advised not to get pregnant because of the associated risks. The risks are higher with chronic diabetes. There is an increased risk to the foetus or mother due to diabetes in pregnancy. Women who are waiting to become pregnant should take folic acid (5 mg/day) until 12 weeks of gestation to reduce the risk of having a baby with a neural tube defect.

48 hours after having unprotected intercourse, a 16-year-old female requested a pregnancy test from her GP. What advice can you give her regarding the reliability of pregnancy testing at this time?
Your Answer:
Correct Answer: Even if conception has already occurred, beta hCG is likely to be normal
Explanation:Even if conception has already occurred, beta hCG is likely to be normal. Beta hCG is made by syncytiotrophoblast cells following conception. It then activates the corpus luteum to continuously produce progesterone for implantation to happen. In week 10/40, levels of HCG peak and the placenta can produce adequate progesterone by itself. As a general rule, a beta HCG concentration >25 U/I or a doubling of levels of HCG within two days is required to diagnose pregnancy. A urine pregnancy test would only likely prove positive around 8 days to 2 weeks following conception.
