Acute hemorrhagic edema of infancy (AHEI) is an unusual form of leukocytoclastic vasculitis that affects children younger than 2 years and frequently is preceded by drug intake, vaccination, or a variety of infections. It is characterized by an abrupt onset of fever, purpuric lesions, and peripheral edema on the face and extremities that may be confused with other dermatoses. The course is benign with spontaneous resolution. We present 2 infants with AHEI and review the clinical manifestations, histology, and differential diagnosis.

The management of anticoagulation and antiplatelet therapy in stage V chronic kidney disease (CKD) patients undergoing renal transplantation remains controversial. Some centers advocate for the use of reversal agents or procoagulants preoperatively, while others suggest that transplantation can proceed safely without halting these treatments. This study aims to evaluate the incidence of hemorrhagic and thrombotic complications in the first 72 hours post-transplant in patients receiving anticoagulant or antiplatelet therapy compared to a control group without such treatments.

Preoperative treatment of PHPT aims to 1) manage severe and/or symptomatic hypercalcemia and 2) prevent postoperative hypocalcemia. Severe hypercalcemia, defined as a blood calcium level ≥ 3.5 mmol/L, requires admission to hospital in a conventional or critical care unit, depending on clinical symptoms and comorbidities.

Unlabelled: Current laboratory protocols for periprosthetic joint infections (PJIs) involve a standard 10- to 14-day incubation period. However, recent evidence indicates considerable variability in the time to diagnosis (TTD) between acute and chronic PJIs. TTD is also influenced by the employed culture media and sample types.
