RESUMO Objetivo: conhecer o perfil epidemiológico dos pacientes com urolitíase, na região do Vale do Paraíba, identificando sua prevalência e distribuição espacial. Métodos: estudo transversal com dados de morbidade por local de residência decorrente de urolitíase no Vale do Paraíba, relativos ao período compreendido entre 2010 e 2012, obtidos do DATASUS. Os dados foram analisados para identificar a prevalência geral, masculina e feminina da urolitíase, a distribuição por idade, tipo de atendimento, estação do ano e sua distribuição espacial. Resultados: ocorreram 1901 atendimentos por urolitíase nos 35 municípios do Vale do Paraíba nos três anos estudados, sendo 52,3% dos pacientes do sexo feminino. Do total, 70,1% dos atendimentos foram em caráter de urgência. Os atendimentos femininos, na sua maioria (67,2%), também foram de urgência (p<0,01). A prevalência geral encontrada para a urolitíase foi 31,7/100.000 habitantes. A prevalência masculina foi 30,7/100.000 e a feminina de 32,7/100.000 (p>0,05). A relação de prevalência encontrada foi 0,9 homens para cada mulher. A faixa etária com o maior número de pacientes atendidos foi entre 30 e 39 anos, com 23,1% do total. Nas estações quentes ocorreram 51,6% dos atendimentos, enquanto nas frias 48,8% (p>0,05). Conclusões: foi possível identificar que na região do Vale do Paraíba o sexo feminino é mais acometido pela urolitíase do que o masculino, fato inédito na literatura. Não se encontrou relação entre a estação do ano e a doença. Foram identificados municípios onde ações de prevenção da litogênese urinária são necessárias.

ABSTRACT Objective: to know the epidemiological profile of patients with urolithiasis in the Paraíba Valley region, identifying its prevalence and spatial distribution. Method: we conducted a cross-sectional study, by residence location in the Paraíba Valley, on morbidity data due to urolithiasis obtained from the DATASUS, covering the period between 2010 and 2012. We aimed at identifying the general, male and female prevalence of urolithiasis, the distribution by age, type of visit, year season and spatial distribution. Results: there were 1,901 visits for urolithiasis in the 35 municipalities of the Paraíba Valley in the three years studied, 52.3% of them of female patients. Of the total, 70.1% of the visits were emergency ones. The feminine visits (67.2%) were mostly also urgent (p <0.01). The overall prevalence for urolithiasis was 31.7/100,000. Male prevalence was 30.7/100,000, and the female, 32.7/100,000 (p>0.05). The prevalence ratio was 0.9 men for every woman. The age group with the highest prevalence was between 30 and 39 years, with 23.1%. Warm seasons concentrated 51.6% of cases, while 48.8% occurred in the cold ones (p>0.05) . Conclusion: women are more affected by urolithiasis than the male in the Paraíba Valley region, an unprecedented in the literature. There was no relationship between the year season and the disease. We identified municipalities where preventive actions of urinary lithogenesis are required.

INTRODUCTION AND OBJECTIVES: The mini sling concept for stress urinary incontinence is an anatomical approach that involves placing a midurethral low-tension tape anchored to the obturator internus muscles bilaterally. They overcome the blind passage of long needles and all the related complications. There are many different devices available and because these are outpatient procedures, primary fixation plays an important role in the outcome. The objective is to evaluate the primary fixation of the various devices of attachment of the commercially available mini-slings through biomechanical tests. MATERIALS AND METHODS: A total of 45 Wistar rats were divided in 3 groups of 15 rats each. They underwent 5 subcutaneous implantation of different mini slings and one polipropilene mesh (control), as follows: TVT-Secur® (Gynecare, USA), Type 1 polypropylene mesh (control); Ophira Mini Sling System® (Promedon, Argentina), Tissue Fixation System® (TFS PTY, Australia), Zipper Sling® and "T device" (Prosurg, USA). The abdominal wall was removed on bloc at different times after implant for biomechanical evaluation, which consisted in application of unidirectional force to the extremity of the fixation system or mesh, until it was completely removed from the tissue using a tension meter (Nexygen 3.0 Universal Testing Machine - LLOYD Instruments). The force was measured in Newtons (N). RESULTS: There was significant difference in the resistance to extraction among the different fixation systems. At 7 days the Ophira Mini Sling System® presented the best fixation and "T dispositive" the worst. CONCLUSION: Ophira mini sling System® presented the best primary fixation at 7º, 14º and 30º days. The impact of this feature in the clinical setting needs to be verified.

Cecal volvulus (CV) establishes the main appearance of the anomalies related to intestinal malrotation. Diagnosis is based on signs and symptoms compatible to intestinal obstructions and complementary examinations as: single radiography form abdomen, opaque enema, computerized tomography and colonoscopy. Therapeutics modalities include: colonoscopy reducing, cecopexy and right colectomy. This article reports a CV case giving emphasis in different diagnosis and therapeutics behaviors.

OBJETIVO: Avaliar o momento do início da bacteriúria e o germe mais freqüentemente relacionado à infecção urinária nos pacientes submetidos à sondagem vesical de demora. MÉTODO: No período de setembro de 2003 a outubro de 2004, foram avaliados os pacientes com 13 anos ou mais, submetidos à operações eletivas com cateterismo vesical de demora. Na inserção do cateter foi colhida a primeira amostra de urina, denominada Amostra 1, e outras seqüencialmente a cada 12 horas. Estas foram analisadas quanto a bacteriúria, leucocitúria, e cultura. A infecção do trato urinário foi definida como a presença de 100.000 unidades formadoras de colônias ou mais, após o isolamento da mesma bactéria ou fungo em culturas de urina de amostras distintas, desde a inserção até a remoção do cateter urinário; a leucocitúria como contagem de leucócitos igual ou superior a 10.000 leucócitos/mm³; e bacteriúria como presença de bactéria de uma única espécie na amostra analisada. RESULTADOS: A amostra foi composta de 63 pacientes, 46 sexo masculino (73%) e 17 sexo feminino (27%). Apenas três deles apresentaram leucocitúria na primeira coleta. Nas Amostras 1 houve variação de 1.000 a 20.000 leucócitos/mm³, todas com cultura negativa. O número de amostras variou de 1 a 8 (84h após a realização do cateterismo vesical). As leucocitúrias nas amostras finais variaram de 1.000 a 204.000 leucócitos/mm³, todas com urocultura e bacteriúria negativa. 62 pacientes (98,4%) utilizaram antibioticoterapia de curta duração para o sítio cirúrgico. CONCLUSÃO: Até 84h - 3,5 dias - não houve Infecção em nenhuma das amostras coletadas e cultivadas. A antibioticoterapia de curta duração pode ter contribuído para o resultado observado.

BACKGROUND: To evaluate the moment of the beginning of bacteriuria and the most frequently germ related to the urinary infection in patients submitted to delayed vesical catheterization. METHODS: During September 2003 to October 2004, patients thirteen-years-old and up, submitted to elective surgeries with long-term vesical catheters were evaluated. By the insertion of the catheter the first urine sample was drawn, and denominated sample 1; other samples were collected subsequently in 12-hour intervals. The samples were analyzed as for the presence of bacteriuria, pyuria, and culture. Urinary tract infection was defined as the presence of 100.000 or more units of bacterial colonies, after the isolation of the same bacterium or fungus in urine cultures from different samples, within the period of catheterization; pyuria was considered positive with a count of 10.000 leucocytes/mm³ or more; and bacteriuria, with the presence of bacteria of a single species in the analyzed sample. RESULTS: The group was composed of 63 patients, 46 male (73%) and 17 female (27%). Only 3 of them presented pyuria in the first collection, with values of 12.000,17.000 and 20.000 leuc/mm³. In the first samples (#1) there was variation from 1.000 to 20.000 leuc/mm³, all of them with negative culture. The number of samples varied from 1 to 8 (84h after the insertion of the vesical catheter). The pyuria in the final samples varied from 1.000 to 204.000 leuc/mm³, all with negative culture and bacteriuria. Sixty two patients (98,4%) received short duration antibiotics for the surgical procedure. CONCLUSION: Until the maximum of 84h - 3,5 days -there was not infection in none of the collected and cultivated samples. The antibiotic fro the surgery itself might have contributed to the observed result.

OBJETIVO: Estimar a prevalência dos incidentalomas renais malígnos no Hospital Universitário de Taubaté (HUT), evidenciados pelo ultra-som. MÉTODO: Estudo transversal e retrospectivo de 1559 prontuários de pacientes submetidos a US abdominais, por indicações que não envolviam sinais ou sintomas relacionados ao tumor renal, no período de maio de 1999 a novembro de 2002. Avaliou-se idade, sexo, indicação do exame, característica da lesão. RESULTADOS: Encontrou-se 102 casos de incidentalomas renais, com a prevalência 6,2% de cistos simples e 0,19% de massas malignas do total dos US realizados. CONCLUSÃO: A prevalência do incidentaloma renal maligno no Hospital Universitário foi de 0,19%, sendo menor que a descrita na literatura. O uso de ultra-sonografia como método de rastreamento populacional deve ser mais bem estudado, pois necessita de elevado número de exames para diagnóstico precoce do tumor renal.

BACKGROUND: To estimate the prevalence of kidney incidentalomas detected by ultrasound (US) at the University Hospital of Taubaté. METHODS: Transversal and retrospective study of 1559 patients with abdominal US, with indications that did not lead to signals or symptoms related to renal tumors. This study was done during May of 1999 through November of 2002. We evaluated age, sex, indication of the examination, and characteristic of the injury. RESULTS: One hundred and two cases of kidney incidentalomas were found, with 6.20% of kidney cysts and 0.19% of malignant kidney tumors. CONCLUSION: The prevalence of incidentaloma with kidney malignancy at the University Hospital was of 0.19%. These results are lesser than that have been described in the literature. The use of US as a screening population method has to be better studied, because it is necessary too many examinations to achieve very low positive diagnosis for kidney cancers.
