Dermatitis Artefacta: A Study of 42 Patients with Management Considerations.

Background: Dermatitis artefacta (DA) is a primary psychiatric disorder in which patients self-inflict skin lesions to attract the attention of family members to release emotions or simply gain compensation. Studies involving patients with DA are difficult to conduct because patients typically move from one hospital to another. Moreover, very little has been written about its treatment, as most published series of cases have been presented without reporting the follow-up.

Hydroxychloroquine may be beneficial as an adjuvant therapy for folliculitis decalvans: a 5-year retrospective study with 49 patients.

Folliculitis decalvans (FD) is a chronic and recurrent neutrophilic scarring alopecia that mostly affects the vertex scalp of young male patients. It manifests as painful alopecic lesions surrounded by pustules, tuftings and intense scalp fibrosis. However, the occurrence of less active or 'lichen planopilaris-like' forms of FD questions the exact role of Staphylococcus aureus in the pathogenic mechanism of this disease.

Delusional infestation treated with risperidone: a series of 27 patients.
