RESUMO
Demodex folliculorum and Demodex brevis are commensal human ectoparasites that reside within or near hair follicles and have been highly associated with rosacea-like papulopustular skin eruptions. We present an interesting case of recurrent, iatrogenic demodicosis in a 56-year-old man. We suspect this to have been triggered by antifungal therapy given it occurred twice closely following azole treatment. We propose that oral antifungals in the setting of immunosuppression can alter the skin microbiome, facilitating Demodex proliferation.

RESUMO
Gout is the commonest cause of inflammatory arthritis among young men. A case of acute gout in a 39-year-old man is described. As part of his assessment, his cardiovascular risk factors were evaluated. He was found to have elevated body mass index, central obesity, hypertension, a family history of cardiovascular disease, and hypercholesterolemia. This case highlights the association between gout, hyperuricaemia and elevated cardiovascular risk. In young male patients, acute presentation with gout in primary care may provide the first opportunity for assessment of cardiovascular risk factors and primary prevention of ischaemic heart disease.

A general approach for the synthesis of 1,5-disubstituted-1,2,4-triazole compounds is described. A series of new oxamide-derived amidine reagents can be accessed in excellent yield with minimal purification necessary. Typically, these amidine reagents are stable crystalline solids and in certain cases were found to exist in a cyclic form as determined by NMR spectroscopy. Under optimized conditions, the direct reaction of these prepared reagents with various hydrazine hydrochloride salts efficiently generates the target triazoles. Both aromatic and aliphatic hydrazines react readily with the amidine reagents under very mild reaction conditions, delivering desired 1,5-disubstituted-1,2,4-triazole derivatives in good yields.
