ReviewAn outbreak of Paederus dermatitis in a suburban hospital in South India: a report of 123 cases and review of literature.
Paederus dermatitis is a peculiar irritant contact dermatitis caused when beetles of the genus Paederus (often called rove beetles) are crushed on the skin, releasing the vesicant pederin. The dermatitis is most frequently seen in regions with a hot, tropical climate. ⋯ An outbreak of paederus dermatitis can occur in tropical regions. Awareness of the condition and its clinical features will prevent misdiagnosis. Simple preventive measures can be undertaken based on the behavioral pattern of this nocturnal beetle.

Longitudinal pigmentation of the nail is very common. The differential diagnosis varies from subungual hematoma, to a fungal infection, to a melanocytic lesion (lentigo, nevus melanoma, etc.) to others. Often, dermatologists do not feel at ease with these pathologies and management is often not clear. ⋯ The use of noninvasive techniques such as dermoscopy has been described to be useful for the preoperative evaluation and the management decision. Using these technique, one will be able to reduce the number of unnecessary surgeries and to choose the most adequate biopsy technique. In this article, we will review the management, including diagnosis as well as differential diagnosis of nail pigmentations and propose a new algorithm for the non invasive diagnosis of nail pigmentation.

Rosacea is a common chronic skin and ocular condition. It is unclear which treatments are most effective. We have conducted a Cochrane review of rosacea therapies. This article is a distillation of that work. ⋯ There is evidence that topical metronidazole and azelaic acid are effective. There is some evidence that oral metronidazole and tetracycline are effective. More well-designed, randomized controlled trials are required to provide better evidence of the efficacy and safety of other rosacea therapies.

The widely accepted standard therapy for cutaneous sarcoidosis includes corticosteroids, antimalarials, and methotrexate. However, a better understanding of the basic immunopathogenic properties of sarcoidosis has elucidated a number of steps critical to the persistence and progression of disease that may be vulnerable to treatment by targeted therapy. This article reviews both standard and newer therapeutic options for cutaneous sarcoidosis.
