Spray de barreira para prevenir o apagamento da marcação cirúrgica na cirurgia micrográfica de Mohs / Barrier spray to prevent surgical marking erasure in Mohs micrographic surgery

A preservação do desenho das margens cirúrgicas é essencial durante a realização da cirurgia micrográfica de Mohs. Contudo, a degermação cutânea no ato da antissepsia e o uso da gaze durante a anestesia local, com frequência, promovem a remoção dessas marcações. A utilização da película protetora Cavilon® 3M, ao fixar a tinta da caneta marcadora, mostrou-se eficaz na preservação do mapa cirúrgico, permitindo uma remoção precisa do espécime cirúrgico

The preservation of the surgical margins marking is essential during Mohs micrographic surgery. However, skin degermation during antisepsis and the use of gauze during local anesthesia often remove these markings. The use of the protective film Cavilon® 3M to fix the marking pen ink was effective in preserving the surgical map, allowing an accurate removal of the surgical specimen.

Brazilian guidelines for diagnosis, treatment and follow-up of primary cutaneous melanoma - Part II

Abstract The last Brazilian guidelines on melanoma were published in 2002. Development in diagnosis and treatment made updating necessary. The coordinators elaborated ten clinical questions, based on PICO system. A Medline search, according to specific MeSH terms for each of the 10 questions was performed and articles selected were classified from A to D according to level of scientific evidence. Based on the results, recommendations were defined and classified according to scientific strength. The present Guidelines were divided in two parts for editorial and publication reasons. In this second part, the following clinical questions were answered: 1) which patients with primary cutaneous melanoma benefit from sentinel lymph node biopsy? 2) Follow-up with body mapping is indicated for which patients? 3) Is preventive excision of acral nevi beneficious to patients? 4) Is preventive excision of giant congenital nevi beneficious to patients? 5) How should stages 0 and I primary cutaneous melanoma patients be followed?.

Novo método para obtenção de derme autóloga para material de preenchimento / A new method for obtaining autologous dermal graft for tissue filler techniques

Vários tipos de materiais sintéticos para preenchimento utâneo têm sido disponibilizados nos últimos anos. Entretanto, substâncias autólogas ainda podem ser consideradas mais vantajosas e seguras. O autor desenvolveu um coletor que facilita a obtenção rápida de derme autóloga já desepitelizada. Descrevem-se o instrumento e detalhes de sua utilização.

Several types of synthetic fi ller materials has been made available in recent years. However, autologous substances can still be considered more advantageous and secure. The author developed a collector that makes it easy to quickly obtain an autologous dermis already deepithelized and he also describes the surgical instrument and details of its use.
