    Purpose: To compare the effectiveness of anal and perianal condylomata treatment using argon plasma and electrofulguration. Methods: From January 2013 to April 2014, 37 patients with anal and perianal condylomata, who had been diagnosed through proctological examination, oncotic cytology, polymerase chain reaction (PCR) and histology, underwent treatment with argon plasma and electrofulguration. The perianal and anal regions were divided into two semicircles. Each semicircle was treated using one of the methods by means of simple randomization. Therapeutic sessions were repeated until all clinical signs of infection by HPV were eliminated. The patients were evaluated according to several variables like the genotype of HPV, HIV infection, oncological potential per genotype, oncotic cytology and histology. Results: Among all the variables studied, only immunosuppression due to HIV influenced the results, specifically when the fulguration method was used. There was no significant difference in effectiveness between argon and fulguration based on lesion relapse (p > 0.05). However, among HIV-positive patients, fulguration presented worse results, with a significant difference (p = 0.01). Conclusion: Regarding treatment of anal and perianal condylomata acuminata, comparison between applying fulguration and argon demonstrated that these methods were equivalent, but use of fulguration presented more relapses among HIV-positive patients.Univ Fed Sao Paulo UNIFESP, Med Sch, Postgrad Program Interdisciplinary Surg Sci, Dept Surg,Div Surg Gastroenterol, Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Med Sch, Dept Surg, Div Surg Gastroenterol, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Escola Paulista Med, Postgrad Program Interdisciplinary Surg Sci, Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, Med Sch, Postgrad Program Interdisciplinary Surg Sci, Dept Surg,Div Surg Gastroenterol, Sao Paulo, SP, BrazillUniv Fed Sao Paulo, Med Sch, Dept Surg, Div Surg Gastroenterol, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Escola Paulista Med, Postgrad Program Interdisciplinary Surg Sci, Sao Paulo, BrazilWeb of Scienc

    OBJECTIVE: to evaluate the role of fibrillar extracellular matrix components in the pathogenesis of inguinal hernias. METHODS: samples of the transverse fascia and of the anterior sheath of the rectus abdominis muscle were collected from 40 men aged between 20 and 60 years with type II and IIIA Nyhus inguinal hernia and from 10 fresh male cadavers (controls) without hernia in the same age range. The staining technique was immunohistochemistry for collagen I, collagen III and elastic fibers; quantification of fibrillar components was performed with an image analysis processing software. RESULTS: no statistically significant differences were found in the amount of elastic fibers, collagen I and collagen III, and the ratio of collagen I / III among patients with inguinal hernia when compared with subjects without hernia. CONCLUSION: the amount of fibrillar extracellular matrix components did not change in patients with and without inguinal hernia.OBJETIVO: avaliar a participação dos componentes fibrilares da matriz extracelular na etiopatogenia das hérnias inguinais. MÉTODOS:foram retiradas amostras da fáscia transversal e da bainha anterior do músculo reto abdominal de 40 homens na faixa etária entre 20 e 60 anos, portadores de hérnia inguinal tipo II e IIIA de Nyhus e de 10 controles constituído por cadáveres frescos, na mesma faixa etária, sem hérnia. A técnica de coloração foi a imunoistoquímica para colágeno I, colágeno III e fibras elásticas e a quantificação dos componentes fibrilares foi realizada através de sistema computadorizado e software de processamento e análise de imagem. RESULTADOS: não foram encontradas diferenças estatisticamente significantes na quantidade de fibras elásticas, colágeno I e colágeno III, e na proporção de colágeno I/III entre os pacientes portadores de hérnia inguinal em comparação com indivíduos sem hérnia. CONCLUSÃO:a quantidade dos componentes fibrilares da matriz extracelular não se alterou nos pacientes com e sem hérnia inguinal.UnifoaUNIFESP-EPMUNIFESP, EPMSciEL

    PURPOSE: To compare morbidity, mortality, recurrence and 5-year survival between D1 and D2 or D3 for treatment of gastric cancer. METHODS: Systematic review and meta-analysis of RCTs. Metaview in RevMan 4.2.8 for analysis; statistical heterogeneity by Cochran's Q test (P50%). Estimates of effect were calculated using random effects model. RESULTS: D2 or D3 was associated with higher in-hospital mortality, with RR = 2.13, p=0.0004, 95% CI, 1.40 to 3.25, I²=0%, P=0.63; overall morbidity showed higher incidence in D2 or D3, RR = 1.98, p50%). Estimativas dos efeitos pelo modelo randômico. RESULTADOS: Maior mortalidade hospitalar em D2 ou D3, RR = 2.13, p=0.0004, 95% IC, 1.40 a 3.25, I²=0%, P=0.63; maior morbidade geral em D2 ou D3, RR = 1.98, p<0.00001, 95% IC, 1.64 a 2.38, I² = 33.9%, P=0.20; maior tempo operatório em D2 e D3, diferença de média ponderal de 1.05, p<0.00001, 95% IC, 0.71 a 1.38, I² = 78.7%, P=0.03; número de reoperações maior em D2 e D3, RR = 2.33, p<0.0001, 95% IC, 1.58 a 3.44, I² = 0%, P=0.99; maior tempo de permanência hospitalar em D2 e D3, diferença de média ponderal de 4.72, p<0.00001, 95% IC, 3.80 a 5.65, I² = 89.9%, P<0.00001; recidiva maior nos grupos D2 e D3, RR = 0.89, p=0.02, 95% IC, 0.80 a 0.98, I² = 71.0%, P = 0.03; mortalidade com doença recidivada maior em D1, RR = 0.88, p=0.04, 95% IC, 0.78 a 0.99, I² =51.8%, P=0.10; 5 anos de sobrevida mostrou diferença estatística não significante, RR = 1.05, p=0.40, 95% IC, 0.93 a 1.19, I² = 49.1% e P=0.12. CONCLUSÕES: Linfadenectomia D2 ou D3 está associada a maior morbidade e maior mortalidade intra-hospitalar; D2 ou D3 apresenta menor incidência de recidiva e menor mortalidade com recidiva, analisadas em conjunto, com heterogeneidade estatística; D2 ou D3 não tem impacto na sobrevida de 5 anos.UNIFOA Clinical Epidemiology and SurgeryUNIFESP Brazilian Cochrane CenterUNIFESPUNIFESP, Brazilian Cochrane CenterUNIFESPSciEL
