RESUMO
Lipedema is a chronic and progressive disease that may compromise lymphatic function. Although suction-assisted lipectomy (SAL) is considered a safe treatment for lipedema patients, the lymphatic repercussions of this surgical procedure are not fully understood. There is not enough evidence to support the role of SAL in lymphatic function treatment in lipedema. Here, we report a case of lymphatic drainage improvement after lipedema treatment with SAL. Tumescent SAL was performed in the deep subcutaneous layer, preserving the superficial and muscular lymphatic vessels. Pre- and postsurgical lymphoscintigraphy was equally documented under the Genoa protocol. A 34-year-old female patient presented with painful enlargement of the arms and lower limbs caused by lipedema. The patient had undergone conservative treatment with mild improvement in pain and heaviness. Lymphoscintigraphy showed slowed radiotracer progression on the left lower limb, collateral and tortuous lymphatic vessels on the right lower limb, and exuberant radiopharmaceutical concentration on the inguinal chain. Nine months after SAL was performed, the patient underwent another lymphoscintigraphy, which exhibited normalized radiopharmaceutical progression time and normal and symmetrical lymphatic vessel patterns. Collateral lymphatic paths and tortuosity vessels were no longer identified. Furthermore, the patient reported significant improvement in pain and the limb's appearance. Tumescent SAL is not only efficient and safe in treating lipedema, but may also be responsible for improvement in lymphatic drainage in lipedema patients. Additional prospective studies are fundamental to reinforce the current evidence and possibly yield predicting information about the tumescent liposuction eligibility in the improvement of lymphatic drainage.
RESUMO
OBJECTIVES: Negative-pressure wound therapy has been widely adopted to reduce the complexity of treating a broad range of acute and chronic wounds. However, its cost is high. The objective of this study was to evaluate the following two different methods of negative-pressure wound therapy in terms of healing time: a low-cost method of negative-pressure wound therapy (a pressure stabilizer device connected to a hospital wall-vacuum system with a gauze-sealed dressing, USP) and the standard of care (vacuum-assisted closure, VAC). METHODS: This is a randomized, controlled, non-inferiority, unblinded trial. Patients admitted with complex injuries to a trauma center in a public referral hospital who were indicated for orthopedic surgery were randomized to a USP or VAC group. The primary outcome was the time required to achieve a "ready for surgery condition", which was defined as a wound bed with healthy granulation tissue and without necrosis or purulent secretion. Wound bed area contraction, granulation tissue growth and the direct costs of the dressings were secondary outcomes. RESULTS: Variation in area and granulation tissue growth were essentially the same between the systems, and healing time was equal between the groups (p=0.379). In both systems, serial debridement increased wound area (p=0.934), and granulation tissue was also increased (p=0.408). The mean treatment cost was US$ 15.15 in the USP group and US$ 872.59 in the VAC group. CONCLUSIONS: For treating complex traumatic injuries, USP was non-inferior to and less expensive than VAC.

Complex wound is the term used more recently to group those well-known difficult wounds, either chronic or acute, that challenge medical and nursing teams. They defy cure using conventional and simple "dressings" therapy and currently have a major socioeconomic impact. The purpose of this review is to bring these wounds to the attention of the health-care community, suggesting that they should be treated by multidisciplinary teams in specialized hospital centers. In most cases, surgical treatment is unavoidable, because the extent of skin and subcutaneous tissue loss requires reconstruction with grafts and flaps. New technologies, such as the negative pressure device, should be introduced. A brief review is provided of the major groups of complex wounds--diabetic wounds, pressure sores, chronic venous ulcers, post-infection soft-tissue gangrenes, and ulcers resulting from vasculitis.

Introdução: A lipoaspiração é um procedimento consagrado para melhora do contorno corporal, sendo que existem diferentes tipos de laser que podem ser aplicados com o objetivo de provocar lipólise e retração da pele. Os parâmetros existentes atualmente (potência e energia) nos aparelhos permitem apenas uma inferência indireta da mudança de temperatura da pele. Métodos: Oitenta e três pacientes, entre 17 e 75 anos, foram submetidos à laserlipólise com diodo 980nm, utilizando uma termocâmera Flir® T540 para monitorização da temperatura. A lipólise foi obtida pela aplicação do laser na camada subcutânea profunda e a retração da pele na derme profunda, com velocidade de 5 centímetros por segundo. Para determinar a temperatura que provoca queimadura na pele, o laser foi aplicado na derme profunda dos retalhos abdominais das pacientes submetidas à dermolipectomia, totalizando 27 casos. Resultados: Na face medial do braço e da coxa foi utilizada uma potência de 15W e foram aplicados em média 4000J de energia por região. Na região dorsal e abdome foi adotada potência de 20W e foram aplicados 6000J em cada quadrante. No submento foram utilizados 10W e aplicados 1500J. Em média, a temperatura inicial do tecido estudado foi de 31°C, e ao final da aplicação do laser foi de 37°C. A temperatura que provocou queimadura foi 45°C. Conclusão: A utilização da termocâmera permitiu uma distribuição mais homogênea do laser e propiciou ao cirurgião uma monitorização eficaz, para que seja aplicada no subcutâneo e na derme profunda uma dose adequada de energia, obtendo-se o efeito desejado.
Introduction: Liposuction is a consecrated procedure to improve body contouring, and various types of laser can be applied to cause lipolysis and skin retraction. The current parameters (power and energy) in the devices allow only an indirect inference of skin temperature change. Methods: Eighty-three patients, between 17 and 75 years old, were submitted to laser lipolysis with 980nm diode, using a Flir® T540 thermocamera for temperature monitoring. Lipolysis was obtained by applying the laser to the deep subcutaneous layer and skin retraction in the deep dermis, with a velocity of 5 centimeters per second. The laser was used in the deep dermis of the abdominal flaps of patients undergoing dermolipectomy to determine the temperature that causes skin burns, totaling 27 cases. Results: A power of 15W was used on the medial side of the arm and thigh, and 4000J average energy was applied per region. In the dorsal area and abdomen, 20W was adopted, and 6000J were applied in each quadrant. On average, the studied tissue's initial temperature was 31°C, and at the end of the laser application was 37°C. The temperature that caused the burn was 45°C. Conclusion: The use of the thermocamera allowed a more homogeneous distribution of the laser and provided the surgeon with effective monitoring so that an adequate dose of energy is applied to the subcutaneous and deep dermis, obtaining the desired effect.

Advances in care of trauma patients and severe abdominal infections are responsible for an increasing number of laparostomies. The management of this entity is complex and several techniques have been described for its treatment. Recently the concept of dynamic closure of the abdominal wall was introduced in the literature with high success rates. The objective of this report is to serve as a foreword for a new approach for the treatment of laparostomy developed at the University Hospital of the University of São Paulo. This is a simple and low cost method, easily performed by a general surgeon. The procedure was also used prophylactically as reinforcement in tight abdominal closures. It is described in detail as well as the results in the first patients. Although promising, refinements and further studies are needed to validate the technique.

OBJECTIVE: The aim of this study was to investigate the efficacy of an infrared GaAlAs laser operating with a wavelength of 830 nm in the postsurgical scarring process after inguinal-hernia surgery. BACKGROUND: Low-level laser therapy (LLLT) has been shown to be beneficial in the tissue-repair process, as previously demonstrated in tissue culture and animal experiments. However, there is lack of studies on the effects of LLLT on postsurgical scarring of incisions in humans using an infrared 830-nm GaAlAs laser. METHOD: Twenty-eight patients who underwent surgery for inguinal hernias were randomly divided into an experimental group (G1) and a control group (G2). G1 received LLLT, with the first application performed 24 h after surgery and then on days 3, 5, and 7. The incisions were irradiated with an 830-nm diode laser operating with a continuous power output of 40 mW, a spot-size aperture of 0.08 cm(2) for 26 s, energy per point of 1.04 J, and an energy density of 13 J/cm(2). Ten points per scar were irradiated. Six months after surgery, both groups were reevaluated using the Vancouver Scar Scale (VSS), the Visual Analog Scale, and measurement of the scar thickness. RESULTS: G1 showed significantly better results in the VSS totals (2.14 +/- 1.51) compared with G2 (4.85 +/- 1.87); in the thickness measurements (0.11 cm) compared with G2 (0.19 cm); and in the malleability (0.14) compared with G2 (1.07). The pain score was also around 50% higher in G2. CONCLUSION: Infra-red LLLT (830 nm) applied after inguinal-hernia surgery was effective in preventing the formation of keloids. In addition, LLLT resulted in better scar appearance and quality 6 mo postsurgery.

CONTEXT: Complications from diabetes mellitus affecting the lower limbs occur in 40 to 70% of such patients. Neuropathy is the main cause of ulceration and may be associated with vascular impairment. The wound evolves with necrosis and infection, and if not properly treated, amputation may be the end result. Surgical treatment is preferred in complex wounds without spontaneous healing. After debridement of the necrotic tissue, the wound bed needs to be prepared to receive a transplant of either a graft or a flap. Dressings can be used to prepare the wound bed, but this usually leads to longer duration of hospitalization. Negative pressure using a vacuum system has been proposed for speeding up the treatment. This paper had the objective of analyzing the effects of this therapy on wound bed preparation among diabetic patients. CASE SERIES: Eighty-four diabetic patients with wounds in their lower limbs were studied. A commercially available vacuum system was used for all patients after adequate debridement of necrotic tissues. For 65 patients, skin grafts completed the treatment and for the other 19, skin flaps were used. Wound bed preparation was achieved over an average time of 7.51 days for 65 patients and 10 days for 12 patients, and in only one case was not achieved. CONCLUSIONS: This experience suggests that negative pressure therapy may have an important role in wound bed preparation and as part of the treatment for wounds in the lower limbs of diabetic patients.

Os avanços nos cuidados com o paciente traumatizado e com infecções abdominais graves são responsáveis por um número crescente de peritoneostomias. O manejo desta entidade é complexo e várias técnicas foram descritas para seu tratamento. Recentemente foi introduzido na literatura o conceito de fechamento dinâmico da parede abdominal, com elevadas taxas de sucesso. O objetivo deste trabalho é de servir como nota prévia de uma nova abordagem para o tratamento das peritoneostomias, desenvolvida no Hospital Universitário da Universidade de São Paulo. Trata-se de um procedimento simples e de baixo custo, facilmente realizado por cirurgião geral. O procedimento também foi utilizado como reforço em fechamentos abdominais tensos, de maneira profilática. O procedimento é descrito em detalhes, assim como os resultados nos primeiros pacientes. Apesar de promissora, refinamentos técnicos e estudos complementares são necessários para a validação da técnica.

Preventing and treating hypertrophic and keloid scars is difficult because of the lack of knowledge about their genesis. Tissue repair can be studied with biocompatible matrices and ex vivo cultures of different cell types. We used an experimental model where collagen gels populated by human fibroblasts underwent progressive contraction, allowing the study of wound healing remodeling. The fibroblast-populated lattices showed the greater contraction of the gel populated by fibroblasts from keloids versus fibroblasts from normal skin. Moreover, fibroblast growth factor (FGF) and transforming growth factor beta (TGF-beta) involved in scar formation were added to the collagen gels populated by normal skin fibroblasts. TGF-beta caused an increase in gel contraction; FGF did not. The mean percentages of contraction of the gels populated by keloid fibroblasts were very similar to the percentages of gels populated by normal skin fibroblasts with added TGF-beta. These observations confirm the existing hypothesis that TGF-beta may be involved in keloid formation.

CONTEXTO: Complicações do diabetes mellitus que afetam os membros inferiores ocorrem em 40 a 70 por cento dos pacientes. A neuropatia é a principal causa de ulceração e pode estar associada com problemas vasculares. A ferida evolui com necrose e infecção, e se não for corretamente tratada poderá terminar em amputação. O tratamento cirúrgico é preferido em feridas complexas, quando não há cicatrização espontânea. Após desbridamento cirúrgico do tecido necrótico do leito da ferida este precisa ser preparado para receber um transplante, seja um enxerto ou um retalho. Curativos podem ser usados para o preparo do leito da ferida, mas frequentemente levam a um longo tempo de hospitalização. A pressão negativa usada através de um sistema vácuo foi proposta para acelerar o tempo de tratamento. O presente trabalho teve como finalidade analisar os efeitos desta terapia no preparo do leito de feridas em pacientes diabéticos. SÉRIE DE CASOS: Oitenta e quatro pacientes diabéticos com feridas em membros inferiores foram estudados. Um sistema vácuo de uso comercial foi utilizado em todos os pacientes após adequado desbridamento de tecidos necróticos. Em 65 pacientes enxertos de pele completaram o tratamento e em outros 19 retalhos cutâneos. O preparo do leito da ferida foi conseguido, em média, em 7,51 dias em 65 pacientes, em 10 dias para 12 pacientes e em somente um caso não foi efetivo. CONCLUSÃO: A experiência sugere que a terapia por pressão negativa possa ter um papel importante no preparo do leito e como parte do tratamento de feridas nos membros inferiores de pacientes diabéticos.

Ferida complexa é uma nova definição para identificar aquelas feridas crônicas e algumas agudas já bem conhecidas e que desafiam equipes médicas e de enfermagem. São difíceis de serem resolvidas usando tratamentos convencionais e simples curativos. Têm atualmente grande impacto sócio-econômico. Esta revisão procura atrair atenção da comunidade de profissionais de saúde para estas feridas, sugerindo que devam ser tratadas por equipe multidisciplinar em centro hospitalar especializado. Na maioria dos casos o tratamento cirúrgico deve ser indicado, uma vez que a perda de pele e tecido subcutâneo é extensa, necessitando de reconstrução com enxertos e retalhos. Nova tecnologia, como uso da terapia por pressão negativa foi introduzido. Breves comentários sobre os principais grupos de feridas complexas: pé diabético, úlceras por pressão, úlceras venosas, síndrome de Fournier e vasculites.

Fasciíte necrotizante da face é uma doença muito rara. Este artigo descreve, pela primeira vez, um caso clínico de um paciente com fasciíte necrotizante de face tratada com o curativo a vácuo desenvolvido na Universidade de São Paulo. Relato do Caso: A infecção do paciente iniciou-se na glândula parótida progredindo para os planos profundos na face, gerando repercussão sistêmica. O tratamento foi baseado em desbridamento cirúrgico seriado e colocação de curativo a vácuo. Após a preparação do leito com este curativo, um retalho de couro cabeludo foi realizado. Este estudo confirma a raridade do caso e expõe as peculiaridades do tratamento, enfatizando a importância do diagnóstico precoce e da abordagem cirúrgica, tanto imediata quanto agressiva para este tipo de infecção grave de partes moles. O paciente foi a óbito em decorrência de choque séptico e falência de múltiplos órgãos, embora a infecção da região cefálica tenha sido controlada e a ferida reduzida. Conclusão: O tratamento com curativo a vácuo pode ser implementado em fasciítes necrotizantes de face com benefícios. O vácuo USP [Universidade de São Paulo] mostrou-se efetivo em seu funcionamento, com menor custo. Contudo, maior número de casos deverá ser tratado com o vácuo USP para sua validação científica comparando-o como produto importado disponível no mercado.
Necrotizing fasciitis of the face is a very rare disease. This article describes for the first time a case report of a patient with an aggressive necrotizing fasciitis of the face treated with the vacuum dressing developed at the University of São Paulo. Case Report: The patient suffered an infection which began on parotid gland progressing to the deep planes in face causing systemic repercussion. The treatment was based on serial surgical debridement and placement of the vacuum dressing. After bed preparation with this dressing, a scalp flap was performed. This study confirms the rarity of the case and elucidates the peculiarities of the treatment, emphasizing the importance of the surgical debridement with early diagnosis and immediate and aggressive approach to this type of severe soft tissue infection. The patient evolved to death by septic shock and multiple organ failure although the infection of cephalic region had been controlled and the wound had been reduced. Conclusions: The treatment with vacuum dressing can be implemented for Necrotizing Fasciitis of the face with benefits. The vacuum USP [University of São Paulo] was effective in its performance, with low cost, but a greater number of cases should be treated with the vacuum USP for its scientific validation comparing with the imported product available.

Introdução: As cicatrizes hipocrômicas pós-queimadura são um problema frequente, quecausa aos pacientes constrangimento social e sofrimento psicológico, uma vez que podemser bastante evidentes, graças aos contrastes de cores de pele que surgem ao seu redor (diferentestons de pele entre a pele normal e a área vizinha à cicatriz - normalmente hipercrômica,e a cicatriz pós-queimadura, hipocrômica). As opções de tratamentos atuais para talproblema não são muito eficientes; estão hoje disponíveis: a maquiagem que apresenta oinconveniente de sair com o passar das horas, ou a tatuagem, que muitas vezes não acompanhao tom da pele normal. Método: Neste trabalho, utilizamos epitélios de queratinócitosautólogos cultivados in vitro como veículo de transporte de melanócitos funcionantes parao tratamento dessas áreas cicatriciais hipocrômicas resultantes de queimaduras. Estes epitélioscultivados serviram como instrumento para a repopulação definitiva destas áreas comcélulas produtoras de pigmento melânico. O método empregado incluiu o cultivo in vitro deepitélios autólogos constituídos por queratinócitos e melanócitos funcionantes, a abrasãosuperficial das áreas a serem tratadas, objetivando a remoção de epiderme hipocrômica, eo transplante dos enxertos autólogos cultivados. Resultados: Os resultados obtidos com aintegração destes epitélios cultivados, ou seja, a restauração e a repigmentação das áreashipocrômicas, foram avaliados por meio do uso de tabelas colorimétricas e biópsias, que demonstrarama repigmentação das cicatrizes e a persistência dos melanócitos transplantados.
Background: Post-burn hypochromic scars can be the subject of great personal sufferingto their victims. Due to the color contrast between the normal and affected skins, they arevisible lesions that embarrass the injured subjects and limit their social performance. Theavailable treatment options in the present days are insufficient, and tend to evolve withpoor results. Methods: We present in this paper the use of in vitro cultivated keratinocyteepithelium as a vehicle for the transplantation of working melanocytes to repopulate thesehypochromic areas in four patients. Results: The results were evaluated with the use of colortables and skin biopsies that allowed us to clearly demonstrate the partial repigmentationof the scar areas and the integration of the transplanted melanocytes. The repigmented skinaverage after 3 and 6 months of the procedure was of 30.52% and 51.66%, respectively. Ifwe consider the low-morbidity of the procedure, these results are already very encouraging,but we strongly believe that technical refinements could allow even better results.
