QuestionChoice
Primary (and tertiary) hyperparathyroidism leads to hypercalcaemia which leads to the deposition of calcium pyrophosphate dihydrate crystals in articular cartilage. This results in flares of pseudogout. Secondary hyperparathyroidism, on the other hand, leads to hypocalcaemia.

Primary hyperparathyroidism
QuestionChoice
This is a risk factor for gout as high purine foods raise uric acid levels which leads to the formation of uric acid crystals. These can build up in articular structures causing gout.

A 45-year-old male presents to clinic with a 5-day history of knee pain.

On examination, the joint is erythematous, hot and swollen. Aspiration of the knee shows calcium pyrophosphate dihydrate crystals.

Given the most likely diagnosis, which of the following is a risk factor?
a
