A) Octreotide
B) Cabergoline
C) Bromocriptine
D) Levothyroxine
E) Desmopressin
Explanations & Answers:
Question Easy Answer: B) Primary hypothyroidism
Question Easy Explanation: The combination of elevated TSH and low free T4 points towards primary hypothyroidism. This condition is caused by the thyroid gland’s inability to produce sufficient thyroid hormones despite adequate stimulation by TSH, leading to the classic symptoms the patient is experiencing. NICE guidelines recommend levothyroxine as the treatment of choice.
Question Medium Answer: E) Ropinirole
Question Medium Explanation: In patients with Parkinson’s disease who have increasing symptoms despite being on levodopa, the addition of a dopamine agonist like ropinirole can be beneficial. NICE guidelines suggest using this in combination therapy to help manage motor symptoms. Amantadine can be used as well, but dopamine agonists are generally preferred for longer-term symptom control.
Question Hard Answer: A) Octreotide
Question Hard Explanation: Octreotide, a somatostatin analogue, is effective in managing acromegaly post-surgery when normalization of growth hormone levels isn’t achieved. It inhibits growth hormone release from the pituitary. According to NICE, octreotide is often used when surgery does not completely control the condition. Cabergoline and bromocriptine are alternatives, especially for patients who are intolerant to or prefer oral therapy but are less effective than somatostatin analogues.
Medical fact of the day: The UK has a high incidence of congenital hypothyroidism due to its comprehensive screening program, catching most cases shortly after birth through the heel-prick test within the first week of life.
