- Estabelecimento de protocolo para armazenamento de pele autógena refrigerada(2017) CONCEIÇÃO, RENATA OLIVEIRA DA; PAGGIARO, ANDRÉ OLIVEIRA; POLO, EUGÊNIO FERRAMUNDO; MARTINES, KARINA; ISAAC, CESAR; CARVALHO, VIVIANE FERNANDES DE; GOMEZ, DAVID DE SOUZA; GEMPERLI, ROLFABSTRACT Introduction: Autologous skin grafts are used for treatment of burn patients. These grafts can be stored and preserved, as long as the storage process is performed with strict quality control to reduce the risk of infection. Methods: A retrospective cohort study was conducted in the Burn Unit of the Hospital das Clínicas de São Paulo from February 2015 to July 2016. During this period, a protocol was established to store refrigerated skin, with control of collection, preservation, and packaging, and recording of all processes. To ensure quality, graft biopsies were collected for preand poststorage microbiology testing and a cross-sectional study for contamination was performed. Results: Critical deficiencies included inadequate packaging, lack of processing records, lack of biopsies for microbiology testing, and failure to discard specimens. Most of the samples were contaminated before and after storage (84.2%). Only two samples were sterile before storage but became contaminated after storage, with growth of Gram-positive skin bacteria. Conclusion: A promising method for the storage of refrigerated skin was established, but requires minor adjustments in quality control.
- Estudo epidemiológico de queimaduras em crianças atendidas em hospital terciário na cidade de São Paulo(2012) MILLAN, Lincoln Saito; GEMPERLI, Rolf; TOVO, Fernando Melhado; MENDAÇOLLI, Thiago Jung; GOMEZ, David Souza; FERREIRA, Marcus CastroBACKGROUND: This study describes the experience with the care of burned children in the Burn Treatment Unit, Division of Plastic Surgery, Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (Hospital of the Faculty of Medicine, University of São Paulo - HCFMUSP) over 15 consecutive months. METHODS: The data of 98 patients up to 13 years of age treated in the Burn Treatment Unit of HCFMUSP from October 2009 to December 2010 were analyzed. RESULTS: The average age of the children was 5.2 years; 67 (68.4%) were boys. Accidents were responsible for burns in 93 (94.9%) cases, whereas 1 (1%) case of burns was caused by aggression. There was a higher incidence of burns in children under 2 years of age. The main agent causing burns was hot liquids (48%), followed by fire (17%) and hot solids (17%). The mean body surface area affected by second- and third-degree burns was 10%. Six (6.1%) patients had burns over more than 20% of their body surface area - 5 (83.3%) of them had burns due to burning alcohol and 1 (16.7%) due to scalding water. All cases in which more than 30% of the body surface was affected by second- and third-degree burns were due to alcohol burns. CONCLUSIONS: This survey demonstrates the importance of burn injuries in pediatric patients. The dataset suggests prevention efforts should focus on the domestic environment, particularly against scalding in children less than 5 years of age. In children older than 5 years, prevention programs should focus on both domestic and extradomestic environments.
- Os desafios no tratamento de paciente grande queimado e politraumatizado com trombose arterial em membro inferior durante a pandemia de COVID-19: relato de caso(2021) TAKEMURA, RAFAEL EIKI; NICOLAS, GREGORY; WADA, ALEXANDRE; GOMEZ, DAVID DE SOUZA; GEMPERLI, ROLF■ ABSTRACT Introduction: The COVID-19 pandemic spread rapidly worldwide, bringing the need for emergency actions to control the disease at the collective and individual level. Thus, the Division of Plastic Surgery and Burns of the largest hospital complex in Latin America was physically aimed at the infected. In this context, we find the challenges of treating a large burned and polytraumatized patient, who presented arterial thrombosis in the lower limb, a rare complication associated with the thermal burn. All treatment was performed in a hospital not specialized in trauma care. Case Report: Case Report: Male patient, 18 years old, without comorbidities, with predominantly third-degree burns of 50% of body surface burned and severe neurotrauma. He presented arterial thrombosis in his right leg 24 hours after the burn. The patient underwent limb amputation and serial surgical interventions for debridement and skin grafting. Despite the prevention protocols, the patient was infected by COVID-19 during hospitalization. Conclusion: This case focuses on a rare complication related to burn injury, which does not yet have diagnostic criteria and defined prophylactic measures. Besides, the COVID-19 pandemic has impacted various health services areas, and it is essential to share knowledge during this pandemic by seeking adaptations to the crisis situation.
- Reconstrução do complexo areolomamilar da mama queimada com retalho trilobado autonomizado(2015) VANA, LUIZ PHILIPE MOLINA; FONTANA, CARLOS; REIS, JULIANA; GOMEZ, DAVID SOUZA; GEMPERLI, ROLFABSTRACT Introduction: Reconstruction of the nipple-areola complex is the final stage of breast reconstruction. The most common nipple reconstruction techniques use local flaps or grafts. However, these techniques in cases of burns produce undesirable outcomes due to the decreased vascularization of damaged skin. The objective of this work was to evaluate the use of the autonomized star flap in the nipple reconstruction of burned breasts. Methods: Nipples were reconstructed in eight female patients in two surgeries each. Results: There were no complications such as necrosis, dehiscence, complete loss of projection of the new nipple, or infection. The mean projection at the end of surgery was 15.25 mm; 6 months after reconstruction, it was 3 mm, showing stability. All patients were satisfied with their results. Conclusion: We conclude that autonomization leads to safe reconstruction of the nipple on burned breasts and maintains a satisfactory minimal projection of the reconstructed nipple.
