Management of Acne Vulgaris

Acne is a primary inflammatory disorder involving the pilosebaceous unit. The
pathogenesis is multifactorial, involving four key factors with interrelated mechanisms: increased sebum production, hyperkeratinization of the follicular infundibulum, inflammation, and Cutibacterium acnes (formerly Propionibacterium acnes). Continue reading

Indications for Antiviral Treatment in Patients with Herpes Zoster

Primary infection with varicella–zoster virus (VZV) results in chickenpox, characterized by viremia with a diffuse rash and seeding of multiple sensory ganglia, where the virus establishes lifelong latency. Herpes zoster is caused by reactivation of latent VZV in cranial-nerve or dorsal-root ganglia, with spread of the virus along the sensory nerve to the dermatome.

Guidelines for the Treatment of Asymptomatic Primary Hyperparathyroidism

The finding of hypercalcemia on routine biochemical testing or in the evaluation of postmenopausal women with osteoporosis is typically the initial clue to the diagnosis of primary hyperparathyroidism. The total serum calcium level, which combines both the free and albumin-bound components of circulating calcium, should be adjusted for the level of albumin. Measurement of ionized calcium may be useful in selected cases, such as in patients with hyperalbuminemia, thrombocytosis, Waldenström’s macroglobulinemia, and myeloma; these patients may have elevated levels of total serum calcium, but normal levels of ionized serum calcium (artifactual hypercalcemia).
