Forensic autopsy costs in the city of São Paulo

CONTEXT: Modern medical practice involves cost analysis of therapeutic and diagnostic procedures. There are no papers dealing with this theme in relation to forensic autopsies in our country. OBJECTIVE: Analysis of direct costs of forensic autopsies. TYPE OF STUDY: Cost analysis. SETTING: São Paulo Medical Examiner's Central Office. SAMPLE: Year 2001 activity. PROCEDURES: Routine forensic autopsies. MEAN MEASUREMENTS: Analysis of direct costs of personnel and material. RESULTS: Cost of personnel represents 90.38% or US$93.46. Material expenses comprised 9.62$ 9.95. Total costs were calculated to be US$ 103.41. CONCLUSIONS: Forensic autopsies have a high cost. Cases to be autopsied should be judiciously selected. Our results are similar to international studies if data are rearranged based on the number of annual necropsies

Influence of the Actual Diameter of the Gastric Pouch Outlet in Weight Loss After Silicon Ring Roux-en-Y Gastric Bypass: An Endoscopic Study

Some sort of restriction of the pouch emptying is supported by many surgeons to allow a sustained weight loss through the use of a ring placed circumferentially around the gastric pouch. Most previous studies focused on the length of the ring, not the actual diameter of the gastric pouch outlet. This study aims to evaluate the association between the actual diameter of the gastric pouch outlet and the weight loss in obese patients submitted to silicon ring Roux-en-Y gastric bypass. We studied prospectively 257 patients that underwent silicon ring (65 mm) Roux-en-Y gastric bypass between July 2005 and August 2007. Upper digestive endoscopy was performed to measure the diameter of the gastric pouch outlet at 1 and 2 years with the aid of calibrated balloons. the diameter of the gastric pouch outlet ranged from 9 to 14 mm (mean = 11 mm). Excess weight loss ranged from 37% to 127% (mean = 69%) during the first year and 29% to 110% (mean = 69%) during the second year. A negative correlation between the diameter of the gastric pouch outlet and excess weight loss at first year (r = -0.792, p < 0.001) and at the second year of follow-up (r = -0.921, p < 0.001) was found. the actual diameter of the gastric pouch outlet was associated with weight loss after silicon ring Roux-en-Y gastric bypass during the 2-year follow-up.Univ Estadual Londrina, Dept Surg, BR-86020041 Londrina, Parana, BrazilUniversidade Federal de São Paulo, Dept Surg, São Paulo, BrazilUniv Estadual Londrina, Div Stat, Londrina, BrazilUniversidade Federal de São Paulo, Dept Surg, São Paulo, BrazilWeb of Scienc

Effects of plastic stenting in commom bile duct of rats: a quantitative reaction analysis using collagen and elastin morphometry Efeitos de prótese plástica em hepatocolédoco de ratos: uma análise quantitativa utilizando morfometria do colágeno e elastina

PURPOSE: To evaluate the effects of biliary stenting in rats through analysis of collagen and elastin deposition in the bile ducts. METHODS: Twenty male rats underwent midline laparotomy, duodenotomy and transampullary stenting of the common bile duct with a 22Fr plastic stent. Animals were randomized in 4 groups, with 5 components in each: (I) control, (II) biliary stenting for 7 days, (III) biliary stenting for 14 days, and (IV) biliary stenting for 30 days. Sections of the common bile duct were stained using Hematoxylin Eosin; Sirius Red to quantitate the amount of collagen present; and Weigert's Resorcin-fuchsin to quantitate the amount of elastin present. RESULTS: The percentage of area stained for collagen was 13.4; 21.5; 29.5 and 32.8, for groups I to IV, respectively. The percentage of area stained for elastin fibers was 7.0; 5.2; 4.0 and 2.9, for groups I to IV, respectively. Collagen/Elastin ratio was 2.4; 5.1; 11.0 and 14.4 for groups I to IV, respectively. CONCLUSIONS: The biliary stenting leads to collagen and elastin deposition in the bile ducts; and collagen deposition and collagen/elastin ratio are proportional to the period of stenting.<br>OBJETIVO: Avaliar os efeitos da colocação de prótese biliar em ratos, analisando a deposição de colágeno e elastina no hepatocolédoco. MÉTODOS: Vinte ratos machos foram submetidos à laparotomia mediana, duodenotomia e colocação transpapilar de uma prótese plástica 22Fr no hepatocolédoco. Os animais foram randomizados em 4 grupos, com cinco componentes cada: (I) controle, (II) prótese biliar por 7 dias, (III) prótese biliar durante 14 dias e (IV) prótese biliar por 30 dias. Cortes do hepatocolédoco foram corados com Hematoxilina Eosina; Sirius Red para quantificar o colágeno; e Resorcina-fucsina de Weigert para quantificar a elastina. RESULTADOS: A porcentagem de área corada para colágeno foi de 13,4; 21,5; 29,5 e 32,8 para os grupos I a IV, respectivamente. A porcentagem de área corada para fibras de elastina foi de 7,0; 5,2; 4,0 e 2,9, para os grupos I a IV, respectivamente. A razão colágeno / elastina foi de 2,4, 5,1, 11,0 e 14,4 para os grupos I a IV, respectivamente. CONCLUSÕES: O implante da prótese biliar leva à deposição de colágeno e elastina nos ductos biliares; e a deposição de colágeno e a relação colágeno / elastina são proporcionais ao tempo de permanência da prótese
