Reconstrução mamária em dois estágios com expansores de tecido e implantes de silicone / Breast reconstruction in two stages with tissue expanders and silicone breast implants

Introdução: A reconstrução mamária imediata com expansor/ implante permanece uma opção importante para mulheres submetidas à mastectomia. O objetivo desse estudo foi avaliar os resultados de reconstrução mamária imediata com emprego expansores e implantes em pacientes submetidas à radioterapia e não submetidas à radioterapia no pós-operatório. Métodos: Foi realizado estudo prospectivo consecutivo com 83 mulheres submetidas à reconstrução mamária imediata com expansores seguido de implantes no período de 2007 a 2012, totalizando 90 reconstruções. No primeiro tempo cirúrgico, o expansor foi colocado em uma bolsa submuscular sob os músculos peitoral maior e serrátil. No segundo tempo, o expansor foi substituído pela prótese. Dois grupos de pacientes foram comparados: (1) pacientes que receberam radioterapia no pós-operatório e (2) pacientes que não receberam radioterapia no pós-operatório. Os resultados foram avaliados em cada grupo nos dois tempos cirúrgicos. Resultados: Trinta e três pacientes receberam tratamento radioterápico (39,8%) no final da expansão. Observamos a ocorrência de 13,25% de complicações no primeiro tempo: deslocamento do expansor (4,8%), esvaziamento (2,4%), infecção (2,4%), deiscência de pele (2,4%) e extrusão (1,2%). No segundo tempo, as complicações foram 17,6%: contratura capsular (7%), extrusão (5,3%), e infecção (5,3%). Com relação aos grupos estudados no primeiro tempo, aqueles que fizeram radioterapia tiveram (18,18%) de complicações e o grupo não exposto à radioterapia apenas (10,0%). No segundo tempo, encontramos 7 (46,6%) complicações para radioterapia e apenas 3 (7,14%) para o grupo não irradiado. Conclusões: Pacientes que receberam radioterapia posteriormente à reconstrução apresentaram maiores índices de complicações.

Introduction: Immediate breast reconstruction with an expander/implant is a good option for women submitted to mastectomy. This study aimed to evaluate the results of immediate breast reconstruction with implants and expanders in patients who did or did not undergo postoperative radiotherapy. Methods: A consecutive prospective study that involved 83 women submitted to immediate breast reconstruction, was carried out by first performing breast reconstruction surgery with expanders and then with implants. The study was conducted between 2007 and 2012 and accounted for a total of 90 reconstructions. In the first surgery, an expander was placed in a submuscular bag under the pectoralis major and serratus muscles. In the second surgery, the expander was replaced by an implant. We compared the surgical outcomes of both types of surgeries (with implants and with expanders) in patients who underwent postoperative radiotherapy and those who did not. Results: After the first surgery, 33 patients (39.8%) received radiotherapy, and 13.25% experienced complications, including expander displacement (4.8%), emptying (2.4%), infection (2.4%), skin dehiscence (2.4%), and extrusion (1.2%). After the second surgery, 17.6% of the subjects experienced complications, including capsular contracture (7%), extrusion (5.3%), and infection (5.3%). With regard to the first surgery, 18.8% of the patients who underwent radiotherapy and 10.0% of those who did not, experienced complications. With regard to the second surgery, these prevalences were 46.6 % and 7.14%, respectively. Conclusion: Patients who received radiotherapy after breast reconstruction surgery experienced more complications.

Abdominoplasty and its effect on body image, self-esteem, and mental health.

The impact of abdominoplasty on the quality of life of abdominoplasty patients was assessed 1- and 6-months postoperatively. Forty women aged 25 to 60 years were divided into study group (25 patients who underwent abdominoplasty) and waiting-list control group (15 patients). Three questionnaires (Body Shape Questionnaire [BSQ], Rosenberg Self-Esteem Scale [RSE/UNIFESP], and Short Form 36 Health Survey Questionnaire [SF-36]) were administered to the study group (preoperatively, 1- and 6-months postoperatively) and control group (on 2 occasions 6 months apart). A significant positive impact on body image, self-esteem, and mental health was found 1- and 6-months postoperatively. Significant differences were observed in role physical, role emotional, and vitality 1-month postoperatively. In the control group, significant differences were found for vitality. There was a significant improvement in Comparative perception of body image (6-month assessment) in the study group compared with controls. Abdominoplasty improved body image, self-esteem, and mental health.

[Brazilian gamma detection device for sentinel lymph node biopsy]. / Equipamento brasileiro de detecção gama intra-operatória para biópsia de linfonodo sentinela.

OBJECTIVE: To test the effectiveness of an intra-operative gamma detection Brazilian device (IPEN) on sentinel lymph node biopsy (SLNB) procedures. METHODS: Forty melanoma or breast cancer patients with indication for undergoing SLNB were studied. Lymphoscintigraphy was done 2 to 24 hours prior to surgery. Lymphatic mapping with vital dye and gamma detection were performed intraoperatively. For gamma detection Neoprobe 1500 was used followed by IPEN (equipment under test) in the first 20 patients and for the remaining half IPEN was used first to verify its ability to locate the sentinel node (SN). Measurements were taken from the radiopharmaceutical product injection site, from SN (in vivo and ex vivo) and from background. It was recorded if the SN was stained or not and if it was found easily by surgeon. RESULTS: There were 33 (82.5%) breast cancer and 7 (17.5%) melanoma patients. Ages varied from 21 to 68 year-old (median age of 46). Sex distribution was 35 (87.5%) women and 5 (12.5%) men. Sentinel node was found in all but one patient. There was no statistical difference between the reasons ex vivo/ background obtained with the measures of both equipments (p=0, 2583-ns). The SN was easily found by the surgeon with both devices. CONCLUSION: The SLNB was successfully performed using either equipment. It was possible to do SLNB with the Brazilian device developed by IPEN without prejudice for the patient.

Equipamento brasileiro de detecção gama intra-operatória para biópsia de linfonodo sentinela / Brazilian gamma detection device for sentinel lymph node biopsy

OBJETIVO: Testar a eficácia de equipamento de detecção gama intra-operatória (DGI) desenvolvido pelo IPEN (Brasil), em procedimentos de biópsia de linfonodo sentinela (BLS) no melanoma e no câncer de mama. MÉTODOS: Foram estudados 40 pacientes portadores de melanoma ou câncer de mama com indicação para realização de BLS.Todos pacientes foram submetidos à linfocintilografia e a BLS ocorreu entre 2 a 24 horas após a mesma. Concomitantemente à DGI, realizou-se o mapeamento linfático com corante vital. Foram feitas leituras com o equipamento convencional Neoprobe® 1500 e com o equipamento em teste (IPEN) dos valores de captação do sítio de injeção do radiofármaco, do LS in vivo e ex vivo e da captação de fundo. Foi registrado se o LS estava corado e se o cirurgião teve facilidade para encontrá-lo. Nos primeiros 20 pacientes utilizou-se o equipamento convencional e depois o de teste; nos outros 20, utilizou-se primeiro o equipamento em teste, com objetivo de verificar se o mesmo identificava primariamente o LS. RESULTADOS: Dos quarenta pacientes, 33 eram portadores de tumor de mama e sete de melanoma cutâneo; variação da idade: 21 a 68 anos (mediana= 46 anos); 35 mulheres e 5 homens. Em apenas um paciente o LS não foi encontrado, nem pela DGI nem pelo corante vital. Não houve diferença estatística entre as razões ex vivo/fundo obtidas com os dois equipamentos (p=0, 2583-ns). CONCLUSÃO: É possível realizar o procedimento de BLS com o equipamento brasileiro desenvolvido pelo IPEN, com facilidade e sem prejuízo para o paciente.

Basal cell carcinoma: an updated epidemiological and therapeutically profile of an urban population.

PURPOSE: To describe the epidemiological profile of basal cell carcinoma patients at a private hospital in São Paulo and to evaluate the treatment adopted. METHODS: A prospective study of 202 patients, on which 253 lesions were diagnosed for histopathological exam as basal cell carcinoma within the period of January 2001 to September 2003, in the Plastic Surgery Residency Program at the Hospital Jaraguá. The susceptibility factor of the host, the environment variables, the characteristics of the lesions and the efficacy of the treatment were examined. The data were statistically evaluated. RESULTS: The incidence of basal cell carcinoma was 126 cases per 100,000 patients in a period of 32 months (36 cases per 100,000 patients/year). The patients were evenly distributed in terms of sex: 48% male and 52% female. The greater incidence was in patients between the ages of 60 and 80 years and the average was 64 years. The survey revealed susceptibility factors such as white race and phototypes I and II in 95.5% of the patients. Exposition to ultraviolet radiation was reported by 77% of the patients and the most frequent location of tumors was on the face (71.2% of the cases). Actinic keratosis and a history of skin cancer were reported in 43.6% and in 25% of the cases, respectively. The adopted treatment was surgery in 99.4% of the cases and only one patient was treated with radiotherapy. Twenty lesions (8%) had incomplete excision. The recurrence rate was 2% (5 cases). There were no cases with metastasis or fatal outcome. CONCLUSIONS: The factors related to the development of basal cell cancer which were significantly present in the population surveyed were: older age, white individuals, phototypes I and II, presence of actinic keratosis, previous history of non-melanoma skin cancer and exposure to ultra-violet rays both in recreational and in occupational form. The surgical treatment employed was effective with a rate of incomplete excision and recurrence similar to those found in the literature.

OBJETIVO: Traçar o perfil epidemiológico dos portadores de carcinoma basocelular e , avaliar o tratamento instituído no Serviço de Residência de Cirurgia Plástica do Hospital Jaraguá. MÉTODOS: Foi realizado um estudo prospectivo de 202 pacientes, nos quais foram diagnosticados 253 lesões por exame anátomo-patológico como carcinoma basocelular no período de janeiro de 2001 a setembro de 2003, no Serviço de Residência de Cirurgia Plástica do Hospital Jaraguá. Foram abordados fatores de susceptibilidade do hospedeiro, fatores ambientais, características das lesões, o tratamento instituído e sua eficácia. Os dados encontrados foram submetidos à análise estatística. RESULTADOS: A incidência de carcinoma basocelular encontrada foi de 126 casos/ 100.000 pacientes em 32 meses (36casos/100.000 pacientes/ano). Os pacientes se distribuíram de forma semelhante entre os sexos masculino (48%), e feminino (52%), com uma incidência maior na faixa etária entre 60 e 80 anos (69%), com média de 64,0 anos. A amostra apresentou fatores de susceptibilidade como a raça branca e fototipos I e II em 95,5% dos pacientes. A exposição à radiação ultravioleta foi informada por 77% dos pacientes, e a localização mais freqüente dos tumores foi a face, em 71,2% dos casos. A ceratose actínica e a história de câncer de pele anterior estavam presentes em 43,6% e 25,8%, respectivamente. O tratamento instituído foi o cirúrgico em 99,4% dos casos, sendo que um caso foi tratado com radioterapia por falta de condições clínicas. No anátomo-patológico foram encontradas 20 lesões (8%) com margens comprometidas pelo tumor. A taxa de recidiva no acompanhamento pós-operatório foi de 2% (5 casos). Não houve casos de metástase ou óbito. CONCLUSÕES: Os fatores relacionados ao desenvolvimento do carcinoma basocelular que estão presentes de forma significante na população estudada são: idade avançada,raça branca, fototipos I e II, presença de ceratose actínica, história anterior de câncer de pele não-melanoma e exposição aos raios ultra-violetas tanto de forma recreacional quanto ocupacional.O tratamento instituído foi efetivo com taxas de margens comprometidas e recidivas comparáveis com as da literatura.

Isolated primary osteoma cutis of the head: Case report.

Osteoma cutis is a rare disease in which there is formation of bony tissue in the skin that causes deformities. The etiology remains unknown and its treatment is controversial. A rare case of primary osteoma cutis in the face and scalp, which was not associated with any syndrome, is described. The patient was treated with surgery and topical retinoic acid. The retinoic acid treatment resulted in an improvement of the frontal area, and stabilized the disease over a two-year follow-up period. Surgical resection was a simple treatment with a quick recovery, minimal scarring and no local recurrence. The patient was followed for two years and presented a satisfactory result.The treatment of osteoma cutis is quite variable, and surgery is the most frequently reported treatment. However, a combination of clinical and surgical treatments seems to be an efficient way to manage these patients.

Experimental model for evaluation of the cutaneous sensitivity of the abdomen

O objetivo deste estudo é relatar e divulgar um modelo experimental para avaliar diversas modalidades de sensibilidade e mapear as áreas da parede abdominal nas quais ocorre diminuição da sensibilidade após abdominoplastia. Dois grupos de pacientes foram estudados: no grupo controle, as paciente não apresentavam incisões abdominais prévias e as pacientes do grupo experimental tinham sido submetidas a abdominoplastia. A avaliação da sensibilidade das pacientes do grupo experimental foi realizada de 12 a 60 meses após a cirurgia. A pele abdominal foi dividida em doze áreas, sendo nove acima e três abaixo da cicatriz da abdominoplastia. As sensibilidades ao toque superficial, dor superficial, ao calor e frio, vibração foram testadas e registradas como positive se a paciente referisse que sentiu o estímulo ou, caso o contrário, negativa. A sensibilidade à pressão foi testada com o uso de diferentes pesos, deste modo, um valor foi obtido quando a paciente sentia a pressão exercida pelo peso. Um teste específico foi utilizado para testar cada modalidade de sensibilidade. O modelo experimental utilizado para testar sensibilidade da pele após abdominoplastia mostrou-se factível em pacientes.

Sensibility of the abdomen after abdominoplasty.

Abdominal skin hypesthesia may occur after abdominoplasty. The purpose of this study was to find out (1) which sensibility modalities are decreased and (2) which areas of the abdominal wall are affected, so that patients can be warned preoperatively about this condition. Forty patients were divided in two groups of 20 patients each. In the control group, patients had no previous abdominal incisions. The sensibility evaluation of patients from the experimental group was made from 12 to 60 months after abdominoplasty, with an average of 31.5 months. These patients were divided into two groups of 10 patients each, a short-term follow-up group (12 to 30 months postoperatively) and a long-term follow-up group (31 to 60 months postoperatively). The abdominal skin was divided into 12 areas; nine were above the abdominoplasty incision and three were below it. Sensibility to superficial touch, superficial pain, and hot and cold modalities was recorded as positive in all areas by a variable number of patients of the experimental group. However, in area 8 (hypogastric area), a statistically significant number of patients had decreased sensibility in all sensibility modalities (Fisher's test and t test). Patients in the experimental group also showed decreased sensibility to hot and cold temperature in area 11 (pubic area). Sensibility to pressure decreased significantly in all areas of the abdomen when compared with the control group (t test). When patients of the short-term follow-up group were compared with those of the long-term follow-up group, there was no statistically significant difference for all modalities of sensibility in the areas studied, except for area 5. In this area it was found that long-term follow-up patients recovered sensibility to cold and hot temperatures. These findings help plastic surgeons to orient their patients about possible risk of exposure to injuries in the areas with decreased sensibility after abdominoplasty. Most importantly, as these patients have decreased sensibility to pressure and hot temperature in a more extensive area of the abdomen, they are exposed to a higher risk of burn injury.

Ondansetron for the prevention of postoperative nausea and vomiting: which is the best dosage for aesthetic plastic surgery?

BACKGROUND: Ondansetron has been used widely in plastic surgery to prevent postoperative nausea and vomiting. A literature search showed controversial dosages of this drug, and because of its short half-life, its use only before anesthetic induction could have a limited effect. The purpose of this study was to assess the efficacy of intravenous (IV) ondansetron (4 mg) for aesthetic plastic surgery performed with the patient under general anesthesia and the prophylaxis of postoperative nausea and vomiting (PONV) in two situations: (a) only before anesthetic induction and (b) before anesthetic induction and immediately before extubation. METHODS: Of the 60 patients who had general anesthesia for aesthetic plastic surgery, 30 received 4 mg of IV ondansetron before anesthetic induction (control group) and 30 received 4 mg of IV ondansetron before anesthetic induction plus 4 mg IV immediately before extubation (experimental group). The PONV was recorded in the postanesthetic care unit and in the hospital room. RESULTS: The total occurrence of PONV (n = 60) was 6.7%. In the postanesthetic care unit, one patient in the experimental group (3.3%) manifested this symptom. In the hospital room, two patients in the control group (6.7%) and one patient in the experimental group (3.3%) manifested PONV. CONCLUSION: According to the findings, there was no statistical difference between the groups. However, the dosage used in the control group was effective and less expensive.

Risk of glove perforation in minor and major plastic surgery procedures.

BACKGROUND: Incidental needlestick injury with exposure of blood pathogens has a high incidence among health care workers. Because plastic surgeons make up an important risk group for this type of accident, this study sought to evaluate the incidence of glove perforation during minor and major plastic surgery procedures. METHODS: Evidence of glove perforation was evaluated for 390 gloves after 100 consecutive minor surgical procedures and for 710 gloves after 100 consecutive major surgeries using Maffuli's test. An index based on the number of first assistant's glove perforation and the surgical time was created to compare these accidents associated with both types of procedures. RESULTS: Glove perforations were found in four gloves (1.02%) after minor surgery and 76 gloves (21.40%) after major surgery. During minor surgeries, the assistant was more likely to have exposure than the surgeon. During major surgery, the surgeon experienced more glove perforations (59.21%) than the assistant (40.79%). The most common location of perforations was the palmar face of the left hand in both groups. The surgeons did not notice these perforations at any time. The duration of the minor procedures varied from 10 to 30 min (average, 17.55 min), whereas the time of major procedures ranged from 1 to 6 h (average, 186 min). There was no statistical significant difference in the perforation's index between minor and major procedures. CONCLUSIONS: The risk of perforation to the surgeon's glove during minor surgery is minimal. The frequency of perforation to the first assistant's glove is similar between minor and major plastic surgery procedures.

Suspicious node found at the time of reduction mammaplasty.

A case of a patient with a suspicious glandular node found during reduction mammaplasty is described. The preoperative search for such nodes, the management of cases on which a suspicious node is found intraoperatively, and a situation on which the diagnosis of breast cancer is made during histology are discussed. When a suspicious small node (with a diameter up to 2 cm) is detected during a cosmetic breast surgery, lumpectomy can be performed. It may be a definite surgical treatment, depending on stage and tumor type. In the case presented, histology revealed intraductal papilloma, a benign tumor, therefore lumpectomy was a suitable procedure with an acceptable cosmetic result. With the increased incidence of breast cancer, this situation will happen more often and technical options for the management of such cases deserves the attention of plastic surgeons.
