Latin American Clinical Practice Guidelines on the Systemic Treatment of Psoriasis SOLAPSO - Sociedad Latinoamericana de Psoriasis (Latin American Psoriasis Society).

This Clinical Practice Guideline on the systemic treatment of Psoriasis includes the recommendations elaborated by a panel of experts from the Latin American Psoriasis Society SOLAPSO, who assessed the quality of the available evidence using the GRADE system and the PICO process to guide the literature search. To answer each question, the experts discussed the results of randomized controlled trials, observational studies and metanalysis evaluating the interventions identified (non-biologics, biologics and phototherapy) in different populations of patients with moderate to severe plaque-psoriasis, which was summarized in Tables ad-hoc. The main end-points considered to assess efficacy were PASI 50, 75, 90 and 100, PGA 0-1 and significant improvement of health-related quality of life.

Actinic Prurigo Cheilitis: A Clinicopathologic Review of 75 Cases.

Actinic prurigo (AP) is a chronic idiopathic photodermatosis that primarily affects American Indians in the United States and Mestizos in Latin American countries. Clinically, the onset of the disease is usually in the first decade of life but may appear initially in adult life, and it is characterized by symmetric involvement of sun-exposed areas of the skin, particularly areas of the face, resulting in polymorphic erythematous papules, macules, and plaques in different stages of evolution. Lower lip involvement includes swelling, scaling, fissures, hyperpigmentation, and ulcerations of the vermilion border.
