Abstract
Objective To evaluate the anatomical and functional renal alterations and the association with post-traumatic arterial hypertension. Methods The studied population included patients who sustained high grades renal injury (grades III to V) successfully non-operative management after staging by computed tomography over a 16-year period. Beyond the review of medical records, these patients were invited to the following protocol: clinical and laboratory evaluation, abdominal computed tomography, magnetic resonance angiography, DMSA renal scintigraphy, and ambulatory blood pressure monitoring. The hypertensive patients also were submitted to dynamic renal scintigraphy (99mTc EC), using captopril stimulation to verify renal vascular etiology. Results Of the 31 patients, there were thirteen grade III, sixteen grade IV (nine lacerations, and seven vascular lesions), and two grade V injuries. All the patients were asymptomatic and an average follow up post-injury of 6.4 years. None had abnormal BUN or seric creatinine. The percentage of renal volume reduction correlates with the severity as defined by OIS. There was no evidence of renal artery stenosis in Magnetic Resonance angiography (MRA). DMSA scanning demonstrated a decline in percentage of total renal function corresponding to injury severity (42.2 ± 5.5% for grade III, 35.3 ± 12.8% for grade IV, 13.5 ± 19.1 for grade V). Six patients (19.4%) had severe compromised function (< 30%). There was statistically significant difference in the decrease in renal function between parenchymal and vascular causes for grade IV injuries (p < 0.001). The 24-hour ambulatory blood pressure monitoring detected nine patients (29%) with post-traumatic hypertension. All the patients were male, mean 35.6 years, 77.8 % had a familial history of arterial hypertension, 66.7% had grade III renal injury, and average post-injury time was 7.8 years. Seven patients had negative captopril renography. Conclusions Late results of renal function after conservative treatment of high grades renal injuries are favorable, except for patients with grades IV with vascular injuries and grade V renal injuries. Moreover, arterial hypertension does not correlate with the grade of renal injury or reduction of renal function.

Abstract
PURPOSE To assess the effects of Roux-en-Y jejunal limb length on gastric emptying and enterogastric reflux. METHODS Seventy male Wistar rats were submitted to antrectomy with Roux-en-Y reconstruction and then were divided into two groups of 35 animals. Group A, short limb (7.5 cm) and Group B, standard limb (15 cm). Group A and B were subdivided into five subgroups each in order to study enterogastric reflux at 30 and 60 minutes and to evaluate gastric emptying at 5, 10 and 15 minutes. In order to measure gastric emptying and enterogastric reflux, radiotracers 99m Tc-Phytate and 99m Tc-DISIDA were respectively used. RESULTS For gastric emptying, the radiotracer concentration was lower in Group A than in Group B after five minutes. The enterogastric reflux was present, but there were no significant differences between enterogastric reflux indexes concerning both A and B Groups. CONCLUSION A standard Roux limb, besides being unable to protect the stomach from the enterogastric reflux, may become a functional barrier for gastric emptying.

Abstract
HYPOTHESIS Replacing a 24-hour regimen with a 1-dose antibiotic prophylaxis for elective surgery would not increase rates of surgical site infection and would decrease costs. DESIGN AND SETTING Before-after trial in a tertiary, private general hospital in Ribeirão Preto, São Paulo, Brazil. PATIENTS Surgery was performed on 6140 consecutive patients from February 2002 through October 2002 (period 1) and 6159 consecutive patients from December 2002 through August 2003 (period 2). Studied surgeries included orthopedic, gastrointestinal, urology, vascular, lung, head and neck, heart, gynecologic, oncology, colon, neurologic, and pediatric surgeries. The study excluded patients with infection at the time of surgery. INTERVENTION Decreasing the 24-hour prophylactic antibiotic regimen to 1-dose antibiotic prophylaxis. MAIN OUTCOME MEASURES Surgical site infections in both periods measured by in-hospital surveillance and postdischarge surveillance; compliance with 1-dose prophylaxis; and costs with cephazolin. RESULTS We followed up 12,299 patients during their hospital stay; postdischarge surveillance increased significantly from 2717 patients (44%) to 3066 patients (50%, P<.001). One-dose prophylaxis was correctly followed in 6123 patients (99% compliance). The rate of surgical site infection did not change in either period (2% and 2.1% respectively, P = .67). The number of cephazolin vials purchased monthly decreased from 1259 to 467 with a corresponding monthly savings of $1980. CONCLUSIONS One-dose antibiotic prophylaxis did not lead to an increase in rates of surgical site infection and brought a monthly savings of $1980 considering cephazolin alone. High compliance to 1-dose prophylaxis was achieved through an educational intervention encouraged by the hospital director and administrative measures that reduced access to extra doses.

Abstract
In Brazil, trauma occupies third place among the various causes of death and is the first cause of death among young people. Among the various approaches to the study of trauma, analysis of the organisation and quality of care has been frequently reported in the literature. The objective of the present study was to assess the quality of care for victims of trauma due to traffic accidents provided at the Emergency Unit of the University Hospital, Faculty of Medicine of Ribeirão Preto, SP, Brazil. The quality of care was compared between two different periods, i.e., before and after the introduction of modifications in prehospital care, and was also compared to the North American standards of the Major Trauma Outcome Study (MTOS). The Trauma Score and Injury Severity Score (TRISS) was used to calculate the probability of survival and the Z statistic was used for comparison with the MTOS. During both periods studied, the results were inferior to those obtained by the MTOS, although positive signs were detected at the Emergency Unit regarding the organisation of the system of trauma care during the study period.

Abstract
Nas últimas décadas, diversas alternativas têm sido propostas para o tratamento do trauma esplênico. O presente estudo procurou comparar o tratamento não-operatório e a cirurgia conservadora na lesão esplênica. Foram analisados, retrospectivamente, os prontuários de 136 portadores de trauma esplênico atendidos na Unidade de Emergência do Hospital das Clínicas da FMRPUSP (1986-1995). Foram utilizados o lnjury Severity Score (1SS) e o Organ lnjury Scaling (OIS) para a definição da gravidade dos casos. Os pacientes foram divididos em dois grupos: grupo A (n=32): conservador não operatório e grupo B (n=104): cirurgia conservadora. As médias de idade, em anos, foram semelhantes (A: 20,31 + 12,43 e B: 25,02 + 14,98; p>0,05). Houve predominância do sexo masculino em ambos os grupos. Os dois grupos diferiram quanto à etiologia (p<0,01). A avaliação das médias do ISS não mostrou diferença significativa (A: 14,21 ± 8,67 e B: 19,44 ± 11,33; p>0,05). Ocorreram complicações em 9,37% e 24,03% dos grupos A e B, respectivamente, mas a diferença não foi significativa (p>0,05). A média de permanência hospitalar foi de 6,68 ± 5,65 e 9,24 ± 9,09 dias, grupos A e B, sem diferença significativa (p>0,05). Concluímos, portanto: o tratamento não-operatório e a cirurgia conservadora do trauma esplênico são condutas equivalentes, sendo opções terapêuticas válidas nas lesões esplênicas de menor gravidade.

Abstract
Apresentamos uma revisão sobre trauma renal, com ênfase na avaliação radiológica, particularmente com o uso da tomografia computadorizada, que tem se tornado o exame de eleição, ao invés da urografia excretora e arteriografia. O sucesso no tratamento conservador dos pacientes com trauma renal depende de um acurado estadiamento da extensão da lesão, classificado de acordo com a Organ Injury Scaling do Colégio Americano de Cirurgiões. O tratamento conservador não-operatório é seguro e consiste de observação contínua, repouso no leito, hidratação endovenosa adequada e antibioti- coterapia profilática, evitando-se uma exploração cirúrgica desnecessária e possível perda renal. As indicações para exploração cirúrgica imediata são abdome agudo, rápida queda do hematócrito ou lesões associadas determinadas na avaliação radiológica. Quando indicada, a exploração renal após controle vascular prévio é segura, permitindo cuidadosa inspeção do rim e sua reconstrução com sucesso, reduzindo a probabilidade de nefrectomia.

Abstract
Para avaliar os efeitos da gastrectomia segmentar do corpo associada à vagotomia gástrica proximal (GS + VGP), sobre a vascularização arterial da curvatura menor do estômago, foram utilizados 24 cães distribuídos em dois grupos de 12 animais, com as seguintes denominações: Grupo I, animais submetidos à laparotomia e manipulação gástrica; Grupo II, animais submetidos à GS + VGP. Em cada grupo, metade dos animais foi sacrificada no terceiro, metade no oitavo dia pós- operatório. No dia do sacrifício, procedeu-se à injeção de mistura de bário-gelatina, na vascularização arterial do estômago. A seguir, o estômago foi removido do animal, fixado em solução de formol, aberto pela curvatura maior e radiografado com técnica padronizada. A intensidade da vascularização da curvatura menor do estômago foi determinada por microdensitometria e morfometria. Pela microdensitometria, foram determinados os valores de densidade óptica, convertidos em equivalentes de milímetros de alumínio, da imagem radiográfica da curvatura menor do estômago. Com base nesses resultados, verificou-se que os valores médios de densidade óptica do grupo II foram significativamente maiores do que o grupo I (p<0,001). Pelo estudo morfométrico de fragmento histológico da curvatura menor, observou-se que os valores médios de volume relativo das arteríolas, em relação ao volume total da camada submucosa, foram significativamente maiores no grupo II em comparação ao grupo I (p<0,001). Os valores médios dos diâmetros das arteríolas da camada submucosa foram significativamente mais elevados no grupo II que no grupo I (p<0,001). O número de arteríolas por mm2 da camada submucosa não diferiu significativamente entre os dois grupos (p>0,05). Embora a execução da GS + VGP implique desvascularização da curvatura menor do estômago, observou-se aumento da intensidade da vascularização arterial desta curvatura nos animais do grupo II, conseqüente à dilatação das arteríolas da camada submucosa.
