• Question 202:

  A 10-month-old boy weighing 3 kg has polyuria, polydipsia and delayed motor milestones. His blood pressure is normal. Blood tests reveal: creatinine 80 mmol/l, sodium 128 mmol/l, chloride 90 mmol/l, potassium 3.0 mmol/l, calcium 2.7 mmol/l, bicarbonate 26 mmol/l and pH 7.46. Ultrasonography shows medullary nephrocalcinosis.

  What is the most likely diagnosis?

  A. Renal tubular acidosis
  B. Bartter's syndrome
  C. Pseudohypoaldosteronism
  D. Diabetes insipidus
  B. Bartter's syndrome

  ---

  Bartter's syndrome Features of Bartter's syndrome are hypokalemia, metabolic alkalosis and hypercalciuria. It is an autosomal-recessive condition leading to tubular defects in sodium chloride transport and increased intrarenal production of PGE2. The blood pressure is normal while the plasma renin and aldosterone levels are raised. Renal stones and nephrocalcinosis are common in this condition. In diabetes insipidus the loss of water raises sodium and potassium levels. Liddle's syndrome is characterized by potassium wasting, hypokalemia and alkalosis, but is associated with low renin and aldosterone production and high blood pressure. In pseudohypoaldosteronism, the sodium level is decreased and potassium is elevated.

• Question 203:

  A man with prostate cancer presents with severe, sudden back pain. His MRI shows cord compression, and he is started on steroids. What is the next best step in management?

  A. Flutamide and leuprolide simultaneously
  B. Leuprolide followed by flutamide
  C. Ketoconazole
  D. Flutamide
  D. Flutamide

  ---

  Flutamide should be started first to block the temporary flare up in androgen levels that accompanies GnRH agonist treatments. When cord compression is described, GnRH agonists, if used too soon, can worsen the compression. Ketoconazole, at a high dose, blocks the production of androgens, but it is not as effective as the other therapies.

• Question 204:

  Patient with severe depression and now he showed some improvement with therapy. The risk of suicide is now:

  A. No risk
  B. Decreases
  C. No change
  D. Increases
  D. Increases

  ---

  At start of the treatment there is an increased suicidal tendency so patient should be carefully monitored for suicidal thoughts.

• Question 205:

  A. Bronchiolitis
  B. Foreign body aspiration
  C. Asthma
  D. Pneumonia

  A. Recurs very late
  B. May present first with lymph node swelling
  C. Mainly spread by blood
  D. Has very favorable diagnosis
  E. Mainly spread by lyphatic

• Question 207:

  72-year-old lady is drowsy and her relatives want to take her home.

  A. ACE inhibitors
  B. Anxiety
  C. Aspirin
  D. Nitrates
  B. Anxiety

  ---

  Anxiety is the most common cause of erectile dysfunction postinfarction. Although beta blockers may be the most common medication associated with erectile dysfunction, anxiety is still a more common cause of erectile dysfunction than beta blockers.

• Question 209:

  Patient with swollen ankles, rales on chest auscultation, protrusion of abdomen, dyspnea. O/E: CVS: No murmurs, JVP shows X, V and Y descent. What is the most likely diagnosis?

  A. Pulmonary HTN
  B. Constrictive Pericarditis
  C. Tricuspid stenosis
  D. Tricuspid regurgitation
  B. Constrictive Pericarditis

• Question 210:

  A 78-year-old woman is admitted to the intensive care unit for acute pulmonary edema. She has rales to the apices and Jugular vein distention. Her EKG shows ventricular tachycardia. Which of the following is the best therapy?

  A. Synchronized cardioversion
  B. Amiodarone
  C. Lidocaine
  D. Unsynchronized cardioversion
  E. Procainamide
  A. Synchronized cardioversion

  ---

  Synchronized cardioversion is used when ventricular tachycardia is associated with acute pulmonary edema. Unsynchronized cardioversion is used for ventricular fibrillation or ventricular tachycardia without a pulse. Medical therapy, such as lidocaine, amiodarone, or procainamide, can be used for sustained ventricular tachycardia that is hemodynamically stable.
