E) Interstitial nephritis

Explanations & Answers:

Question Easy Answer:
B) Benign prostatic hyperplasia (BPH)

Question Easy Explanation:
The gentleman’s symptoms of nocturia, urinary frequency, and hesitancy are classic signs of benign prostatic hyperplasia (BPH), a common condition in older men. According to NICE guidelines, it is characterized by these urinary symptoms without evidence of infection or significant pain.

Question Medium Answer:
D) Nitrofurantoin

Question Medium Explanation:
For uncomplicated UTIs, nitrofurantoin is recommended as a first-line treatment by NICE and NHS guidelines due to its efficacy and resistance profile. Trimethoprim is an alternative, but nitrofurantoin remains preferable unless contraindicated.

Question Hard Answer:
B) Nephrotic syndrome

Question Hard Explanation:
The patient’s presentation of proteinuria greater than 3.5 g/day, hypoalbuminemia, and hyperlipidemia fits the criteria for nephrotic syndrome. This condition is distinct from nephritic syndrome, which involves more inflammatory signs such as hematuria. NICE and BNF guidelines align with these diagnostic criteria for nephrotic syndrome.

Medical fact of the day: Did you know that the kidney can survive with only 10% of functional tissue? This remarkable regenerative capability is why individuals can live healthy lives with just one kidney or after significant renal injury.

Quote of the day: “In every patient encounter lies a chance to heal beyond the physical—remember, we mend the heart and soul too.”
