Chronic Early-Stage Ocular Cicatricial Pemphigoid.

Ophthalmic Plast Reconstr Surg 2021 Jul 21. Epub 2021 Jul 21.

Columbia University, Vagelos College of Physicians and Surgeons, New York, New York, U.S.A. Department of Ophthalmology, Edward S. Harkness Eye Institute, Columbia University Irving Medical Center, New York, New York, U.S.A.

Ocular cicatricial pemphigoid (OCP) represents an insidious, autoimmune-mediated disease of the conjunctiva, initially presenting as chronic conjunctivitis and progressing to fibrosis, cicatrization, and eventually blindness secondary to corneal keratinization. This series reports 3 cases presenting with chronic conjunctivitis lasting an average of 10 years without cicatrix formation, ultimately diagnosed as OCP based on direct immunofluorescence of conjunctival biopsy samples. This chronic conjunctivitis without fibrosis suggests the possibility of an OCP subtype with a prolonged early stage or prodrome prior to cicatrization, which may benefit from early diagnosis and treatment to prevent complications of this disease.

J Breath Res 2021 Jul 22. Epub 2021 Jul 22.

Emergency Medicine and Critical Care, Saitama Medical Center, 1981 Kamoda, Kawagoe, Saitama, 350-8550, JAPAN.

The coronavirus disease 2019 (COVID-19) pandemic has imposed a considerable burden on hospitals and healthcare workers (HCWs) worldwide, increasing the risk of outbreaks and nosocomial transmission to "non-COVID-19" patients, who represent the highest-risk population in terms of mortality, and HCWs. Since HCWs are at the interface between hospitals on the one hand and the community on the other, they are potential reservoirs, carriers, or victims of severe acute respiratory syndrome coronavirus 2 cross-transmission. In addition, there has been a paradigm shift in the management of viral respiratory outbreaks, such as the widespread testing of patients and HCWs, including asymptomatic individuals. Read More
