Standard surgical treatment for benign prostatic hyperplasia is safe for patients over 75 years: analysis of 100 cases from a high-volume urologic center
OBJECTIVES: In this study, we aimed to determine the complications of standard surgical treatments among patients over 75 years in a high-volume urologic center. METHODS: We analyzed 100 consecutive patients older than 75 years who had undergone transurethral prostatic resection of the prostate or open prostatectomy for treatment of benign prostatic hyperplasia from January 2008 to March 2010. We analyzed patient age, prostate volume, prostate-specific antigen level, international prostatic symptom score, quality of life score, urinary retention, co-morbidities, surgical technique and satisfaction with treatment. RESULTS: Median age was 79 years. Forty-eight patients had undergone transurethral prostatic resection of the prostate, and 52 had undergone open prostatectomy. The median International Prostatic Symptom Score was 20, the median prostate volume was 83 g, 51% were using an indwelling bladder catheter, and the median prostatespecific antigen level was 5.0 ng/ml. The most common comorbidities were hypertension, diabetes and coronary disease. After a median follow-up period of 17 months, most patients were satisfied. Complications were present in 20% of cases. The most common urological complication was urethral stenosis, followed by bladder neck sclerosis, urinary fistula, late macroscopic hematuria and persistent urinary incontinence. The most common clinical complication was myocardial infarction, followed by acute renal failure requiring dialysis. Incidental carcinoma of the prostate was present in 6% of cases. One case had urothelial bladder cancer. CONCLUSIONS: Standard surgical treatments for benign prostatic hyperplasia are safe and satisfactory among the elderly. Complications are infrequent, and urethral stenosis is the most common. No clinical variable is associated with the occurrence of complications

Genetic gains for grain yield by irrigated rice breeding program in the Mid-North Region of Brazil
Objetivando avaliar os progressos obtidos pelo programa de melhoramento genético do arroz (Oryza sativa L.) irrigado, desenvolvido no meio-norte do Brasil, foram analisados os dados de produtividade de grãos, floração média, altura de planta e acamamento das linhagens componentes de 37 ensaios comparativos avançados, conduzidos de 1984 a 1997. Além das testemunhas ('Cica 8' e 'Metica 1'), 89 linhagens foram contempladas neste estudo. Nesse perÃodo, o ganho médio anual de produtividade foi de apenas 0,3%, significativo (p < 0,05), porém de baixa magnitude. As correlações genéticas estimadas pelos métodos convencional e indireto foram de magnitudes semelhantes. Das seis cultivares recomendadas para cultivo no perÃodo avaliado, a Diamante proporcionou ganhos consideráveis quanto à qualidade dos grãos, em comparação com as testemunhas.Data from 37 advanced yield trials, conducted from 1984 to 1997, were analyzed to evaluate the genetic progress made by the Brazilian Mid-north Region irrigated rice (Oryza sativa L.) breeding program. The following traits were measured: grain yield, days to flowering, plant height, and lodging. These trials had 89 breeding lines and two checks ('Cica 8' and 'Metica 1'). During these 14 years of experiments, the annual gain for grain yield was small and equal to 0.3%, but statistically significant (P < 0.05). The genetic correlations estimated by the conventional and indirect methods were similar. Out of the six cultivars recommended for the region during this period, the cultivar Diamante provided significant gains for grain quality, when compared to the checks
Obesity may influence the relationship between sex hormones and lower urinary tract symptoms
Obesity may influence the relationship between sex hormones and lower urinary tract symptoms
PurposeThe effects of serum testosterone in the lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH) are not well established. The objective of the study is to evaluate the association of sex hormones with LUTS and control the results by patient weight.Materials and MethodsThe study comprised a cross-sectional analysis of 725 men included in a prostate cancer screening program at University of Sao Paulo Medical School. The serum concentrations of total testosterone (TT), free testosterone (FT) and sex hormone binding globulin (SHBG) were measured. Variables analyzed were age, American Urological Association (AUA) symptom score, storage symptoms, voiding symptoms, quality of life score, prostate specific antigen levels and prostate volume. Obesity was measured through the calculation of body mass index (BMI). A regression analysis model was performed.ResultsMedian patient age was 65 years (48 to 94). A higher TT level was significantly associated with a severe AUA symptom score only among patients with a BMI ≥ 25. Median TT was 371, 370 and 427ng/dL (p = 0.017) in patients with mild, moderate and severe LUTS respectively. The multivariate regression analysis in patients with BMI ≥ 25 showed that only age, TT and sex score were related to LUTS.ConclusionsA higher TT is associated with a severe AUA score symptom index only in obese patients. Further analysis are necessary to evaluate the mechanisms through which testosterone may influence LUTS in these patients
