Acute Hemorrhagic Infancy of Edema: A Purpuric Rash in 6-Month-Old Infant.

J Investig Med High Impact Case Rep 2021 Jan-Dec;9:23247096211017413

Emory University, Atlanta, GA, USA.

Acute hemorrhagic edema of infancy (AHEI) is a cutaneous leukocytoclastic vasculitis presenting with purpura, ecchymosis, fever, and edema. Pediatricians must effectively differentiate AHEI from other diseases that have similar presentations but are more severe in order to treat appropriately without overutilizing expensive, unnecessary diagnostic tests. In this article, we describe a case of a 6-month-old previously well male who presented to our institution with a worsening rash and fever. Read More

Azathioprine hypersensitivity syndrome: report of two cases.

BMJ Case Rep 2021 May 19;14(5). Epub 2021 May 19.

Pharmacy, Cairns Base Hospital, Cairns, Queensland, Australia.

Azathioprine hypersensitivity syndrome is a rare but potentially severe side effect of azathioprine use. It has a variable and non-specific presentation making it difficult to distinguish from sepsis or disease relapse. High clinical suspicion is therefore required for recognition and prompt cessation of azathioprine for symptom resolution. Read More

Int J Retina Vitreous 2021 May 7;7(1):37. Epub 2021 May 7.

Department of Ophthalmology, Federal University of São Paulo, São Paulo, Brazil.

Background: Intraocular inflammation is an uncommon but potentially vision-threatening adverse event related to anti-VEGF therapy. This is of increasing importance given both the volume of injections performed, as well as the increased prevalence of inflammation seen with newer anti-VEGF agents. Brolucizumab, the newest anti-VEGF agent, has been associated with an inflammatory retinal vasculitis and the underlying mechanism is unclear. Read More
