RESUMO
En base a un diagnóstico circunstancial de dos casos de brucelosis en un hato bovino del distrito de Codo del Pozuzo, Huánuco, se llevó a cabo un estudio de prevalencia de Brucellasp. en 5439 bovinos entre abril a junio de 2007. Dos bovinos resultaron positivos a la prueba de Rosa de Bengala, pero negativos a la prueba confirmativa de Fijación del Complemento. El modelo de simulaciones estocásticas de distribución beta mostró una prevalencia de 0.02% con intervalo de confianza mínimo de 0 y máximo de 0.06%.
A seroprevalence study on 5439 cattle from April to June 2007 was conducted based on a circumstantial diagnosis of two cases of bovine brucellosis in the district of Codo del Pozuzo, en the region of Huanuco. Two animals resulted positive to the Rose Bengal test but negative to the Complement Fixation test. The beta distribution using a simulation model showed a prevalence of 0.02% with a minimum interval of confidence of 0 and maximum of 0.06%.

INTRODUCTION: Miguel Hidalgo Hospital in Aguascalientes is dependent from the Federal Secretary of Health and operates in integrity with State health system in Aguascalientes. It capacity is based on 132 censored beds and 71 no censored beds. Is considered a specialty hospital in the region of Bajío. Renal transplant program activity was initiated in 1990 and gives care for adult and pediatric population. MATERIAL AND METHODS: Retrospective, comparative and longitudinal study to describe and analyze our experience. Data base and clinical charts of renal transplant recipients were reviewed. Age, gender, date of transplant, etiology of renal disease, type of donor, HLA compatibility and PRA, immunosuppressive therapy, acute rejection, serum creatinina, graft loss and mortality were registered. Statistical analysis included 2, unpaired Student T test and Kaplan-Meier survival analysis with Log Rank test. Cox Analysis was also done. RESULTS: 1050 renal transplants were done from November 1990 to June 2011. 50 were excluded because follow-up was not longer than 3 months. 1000 consecutive renal transplant patients from January 1995 to June 2011 were included for analysis. Patients were divided in 2 groups: group A transplanted January 1995 to December 2004; group B transplanted January 2005 to June 2011. Etiology for end stage renal disease is unknown in 61% of cases, 11% developed renal disease to diabetes mellitus. 93% patient survival was observed at median follow-up and 84.9% graft survival at median follow-up (6 years). Biopsy proven acute rejection in group A 19.9 vs. 10% in group B. Two haplotype matching shows 92% graft survival. Diabetic patients exhibit 73% graft survival vs. other as hypertension (87%). PRA >0 and serum creatinine > 2.0 mg/dL increase risk for graft loss according to Cox analysis. CONCLUSION. Results are comparable to international data. Importance of developing regional transplant centers is emphasized.
