Tratamento da poroqueratose actínica superficial disseminada com laser 1340-nm Nd: YAP / Treatment of disseminated superficial actinic porokeratosis with 1,340nm Nd:YAP laser

Este estudo demonstrou o resultado clínico e histológico do tratamento com laser fracionado não ablativo de paciente com poroqueratose actínica superficial disseminada. A paciente recebeu sete sessões de laser 1340-nm Nd:YAP, com intervalos de quatro a cinco semanas. Biópsias e fotos foram realizadas antes e após o tratamento, o qual foi bem tolerado e trouxe melhora do eritema e da textura das lesões. O seguimento foi de um ano. O exame anatomopatológico após o tratamento revelou pouca modificação da lamela cornoide.

This study demonstrated the clinical and histologic result of the treatment of one disseminated superficial actinic porokeratosis patient with non-ablative fractional laser. The patient was treated with seven sessions of 1340-nm Nd:YAP laser, with 4 or 5 week-intervals. Biopsies and photographs were performed before and after treatment, which was well tolerated and lead to improvement in the erythema and texture of the lesions. There was a 1-year follow-up. Histopathologic examination after treatment revealed little changes in the cornoid lamella.

Corymbiform syphilis associated with three other sexually transmitted infections

Abstract: Secondary syphilis can have different clinical presentations, with corymbiform rash as its rarest manifestation. The disease is characterized by a central papule surrounded by smaller ones. We report the case of a man who has sex with man with corymbiform syphilis. The patient was subsequently diagnosed with HIV infection, hepatitis B, non-gonococcal urethritis, as well as infection of the central nervous system by treponema. This case not only illustrates a rare presentation of secondary syphilis, but also demonstrates the importance of further investigation of sexually transmitted infections, particularly among at-risk patients.
