Orf (Ecthyma Contagiosum) Transmitted from a Camel to a Human: A Case Report.

BACKGROUND Orf, also known as ecthyma contagiosum, is a zoonotic disease caused by a parapox virus, which is endemic in goats and sheep but rare in camels. Orf is usually transmitted to humans who are in contact with infected animals. The clinical manifestation of the disease and a personal history of contact with an infected animal are sufficient to diagnose orf virus infection.

Crescent-Shaped Hyperpigmentation Following Laser Hair Removal: Case Series of Fifteen Patients.

Background And Objectives: Post-inflammatory hyperpigmentation (PIH) is a common adverse effect of laser hair removal procedures. This case series emphasizes the under-reported crescent-shaped form of PIH that may occur following laser therapy. This case series sought to assess the potential causes of the distinct, crescent-shaped form of PIH that may arise following laser hair removal procedures, and to examine the concept of thermal versus cryogenic damage, which was discovered accidentally due misalignments between laser-cryogen spurts.
