Non-Steroidal Topical Therapy for Facial Seborrheic Dermatitis.

Seborrheic dermatitis (SD) is a chronic, recurrent, inflammatory skin disorder occurring in areas rich in sebaceous glands. It manifests clinically as erythematous macules or plaques with varying levels of scaling and associated pruritus. Although the pathogenesis of SD has yet to be fully understood, Malassezia yeasts, hormones, sebum levels, and immune response are known to play important roles.

[Trichotillomania: three cases presentation and diagnosis tests review].

Trichotillomania represents a chronic disorder in which patients traumatically remove their own hair in a bizarre pattern. Like obsessive-compulsive disorder, the hair-pulling behavior is recognized as senseless and undesirable, but is performed in response to several emotions and affects, such as increasing anxiety, or unconscious conflicts with a resultant tension relief. The condition may be episodic, but is usually chronic and difficult to treat.
