Summary of the ACC/AHA Guideline on the Treatment of Blood Cholesterol to Reduce ASCVD

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).

Indications for Therapy and for Neurosurgery in Patients with Prolactinomas

In contrast to macroadenomas, for which therapy is routinely indicated, microadenomas do not always require treatment. For patients with microadenomas who do not have these indications, symptoms and prolactin levels can be monitored, and MRI can be used to follow the size of the tumor.
