Vitamin B12-induced acneiform eruption.

Cutaneous acneiform eruptions are a side effect of many medications, including vitamin B12 therapy. However, reports of vitamin B12-induced acne are rare. We present a 67-year-old woman with a new diagnosis of pernicious anemia who developed a sudden acneiform eruption on the face after treatment with high-dose vitamin B12.

Phone-based telemonitoring of arterial hypertension versus usual care: the HOROSCOPE study.

The Horoscope trial aimed to assess the efficacy of home blood pressure (BP) telemonitoring (TLM) in controlling BP reduction in hypertensive patients compared with usual care. This is a multi-center, prospective randomized, parallel-group trial comparing TLM with usual care during a period of 6 months in patients with hypertension. We included 525 patients randomly assigned in a 1-1 ratio to telemonitoring (TLM group; n = 260) or usual care (control group; n = 265).

Pseudomyogenic hemangioendothelioma presenting as a penile lesion.

Pseudomyogenic hemangioendothelioma (PHE) is a rare, usually multifocal neoplasm typically affecting individuals in the second-to-fourth decade of life, with a male predominance. It often arises in the distal extremities and characteristically involves multiple tissue planes. Presentation of this neoplasm as a primary penile lesion is exceedingly rare, with only five cases previously documented in the literature.
