Guía clínica chilena para el estudio y tratamiento de hidradenitis supurativa. Resumen ejecutivo

Hidradenitis suppurativa is a chronic inflammatory disease of the hair follicle characterized by recurrent painful and inflamed lesions, predominantly affecting intertriginous regions. Due to its physical sequelae and impact on quality of life, we should be familiarized with this disease to make an appropriate diagnosis and implement an early treatment. This executive summary of the clinical guideline, elaborated by the hidradenitis suppurativa workgroup of the Chilean Society of Dermatology and Venereology (SOCHIDERM), reviews its definition, epidemiology, pathophysiology, risk factors, comorbidities, psycho-emotional impact, clinical presentation, diagnosis, classifications, ultrasonographic evaluation, and its medical and surgical treatments. Finally, a therapeutic approach algorithm is proposed.

Guía clínica chilena para el manejo de hidradenitis supurativa / Chilean clinical guidelines for the management of hidradenitis suppurativa

La hidradenitis supurativa es una enfermedad inflamatoria crónica del folículo piloso que se caracteriza por la aparición recurrente de lesiones inflamatorias dolorosas y profundas predominantemente en pliegues. Debido a sus secuelas físicas y en la calidad de vida, debemos estar familiarizados con esta enfermedad, a fin de poder realizar un diagnóstico oportuno e implementar un tratamiento precoz. Esta guía clínica, elaborada por el grupo de trabajo de hidradenitis supurativa de la Sociedad Chilena de Dermatología y Venereología (SOCHIDERM), revisa su definición, epidemiología, fisiopatogenia, factores de riesgo, comorbilidades, impacto psicoemocional, presentación clínica, diagnóstico, clasificaciones, evaluación ecográfica, y tratamientos médico y quirúrgico. Finalmente se propone un algoritmo de enfrentamiento terapéutico.

Manifestaciones cutáneas en donantes de sangre portadores de HTLV-1 en comparación con donantes de sangre no portadores de HTLV-1 / Cutaneous manifestations detected in human T cell lymphotropic virus type 1 infected Chilean blood donors

Background: Most human T cell lymphotropic virus type 1 (HTLV-1) infected individuals are asymptomatic, but they commonly present cutaneous lesions that could be considered warning signs of the disease. Aim: To identify the main cutaneous manifestations present in HTLV-1 infected blood donors and compare them with healthy donors. Materials and Methods: Two blood donor groups from the blood bank of an emergency hospital were matched according to gender and age. One group was formed by HTLV-1 (+) (cases) and the other by HTLV-1 (-) donors (controls). A blind examiner to the serologic condition, evaluated their cutaneous manifestations. Results: Twenty five cases and 25 controls aged 18 to 60 years (24 females) were evaluated. One or more cutaneous manifestations were found in 24 (96%) cases and in 15 (60%) controls (p < 0.01). Inflammatory cutaneous diseases were found in 19 (76%) cases and in 9 (36%) controls (p < 0.01). Dermatophytosis was found in 18 (72%) cases and in 12 (48%) controls (NS). Conclusions: HTLV-1 infected Chilean subjects have a higher frequency of dermatoses than their healthy counterparts.

Efficacy of topical photodynamic therapy for keratoacanthomas: A case-series of four patients.

Topical photodynamic therapy (PDT) is an excellent treatment option for various non-melanoma skin cancers and precancerous lesions, including actinic keratosis, Bowen's disease, and basal cell carcinoma. The clinical use of PDT includes a broad range of neoplastic, inflammatory, and infectious skin diseases. There is also anecdotal evidence suggesting the efficacy of PDT for the treatment of keratoacanthomas (KA). We report a case-series of four patients with solitary KA confirmed by histology, treated with topical PDT with methylaminolevulinic acid (MAL) cream. After three sessions of PDT, the lesions completely disappeared. There was no evidence of recurrence and excellent cosmetic outcome was achieved after three years of follow-up. Topical photodynamic therapy with MAL can be a therapeutic alternative for KA with good clinical and cosmetic outcomes.
