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 prostate-specific 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.

Are we able to correctly identify prostate cancer patients who could be adequately treated by focal therapy?

Introduction and Objective: Because of the improvements on detection of early stage prostate cancer over the last decade, focal therapy for localized prostate cancer (PC) has been proposed for patients with low-risk disease. Such treatment would allow the control of cancer, thereby diminishing side effects, such as urinary incontinence and sexual dysfunction, which have an enormous impact on quality of life. The critical issue is whether it is possible to preoperatively predict clinically significant unifocal or unilateral prostate cancer with sufficient accuracy. Our aim is to determine whether there is any preoperative feature that can help select the ideal patient for focal therapy. Material and methods: A total of 599 patients who underwent transrectal ultrasound, (TRUS)-guided prostate biopsy followed by radical prostatectomy to treat PC were examined in our laboratory between 2001 and 2009. We established very restricted criteria to select patients with very-low-risk disease for whom focal therapy would be suitable (only I biopsy core positive, tumor no larger than 80% of a single core, no perineural invasion, PSA serum level < 10 ng/ml, Gleason score < 7 and clinical stage T1c, T2a-b). We defined 2 groups of patients who would be either adequately treated or not treated by focal therapy. The primary endpoint was the evaluation of preoperative features in order to identify which parameters should be considered when choosing good candidates for focal therapy. Results: Fifty-six out of 599 patients met our criteria. The mean age was 59 years, and the mean number of biopsy cores was 14.4. Forty-seven (83.9%) were staged T1c, and 9 (16.1%) were staged T2a-b. Forty-four (78.6%) patients could be considered to have been adequately treated by focal therapy, and 12 (21.4%) could not. There was no statistical difference between the 2 groups considering age, clinical stage, PSA levels, Gleason score, and tumor volume in the biopsy. All 12 patients who could be considered inadequately treated had a bilateral, significant secondary tumor, 58.3% had Gleason >= 7, and 25% were staged pT3. Conclusion: Although focal therapy might be a good option for patients with localized prostate cancer, we are so far unable to select which of them would benefit from it based on preoperative data, even using very restricted criteria, and a considerable proportion of men would still be left undertreated.

Fitas adesivas, “Vanish” e técnica clareadora caseira: aspectos importantes a serem considerados

Em trabalhos experimentais, o peróxido de hidrogênio revelou-se um promotor da carcinogênese química bucal e em outras mucosas gastrintestinais. O peróxido de hidrogênio representa um cocarcinógeno, pois não inicia sozinho uma neoplasia maligna epitelial, mas pode potencializar outros agentes iniciadores. Na boca, onde atuam vários carcinógenos, a mucosa está, em sua maior parte, desprotegida, pois não tem em sua superfície uma espessa e contínua camada de queratina, como a pele. Em qualquer forma de ação, o peróxido de hidrogênio - o único clareador de dentes - requer técnica que proteja a mucosa e a região cervical do esmalte na junção com o cemento, e dificulte que seja engolido, indo para as partes mais inferiores do trato gastrintestinal. Este trabalho centra-se principalmente na necessidade de convencer pacientes, profissionais e agentes do mercado de que a forma mais correta e segura de clarear dentes está no consultório dos profissionais treinados e conscientes.

Incontinência urinária autorreferida no pós-parto: características clínicas

Este estudo transversal teve como objetivo caracterizar as manifestações de incontinência urinária autorreferida no pós-parto. Foram entrevistadas 288 mulheres atendidas em um Centro de Saúde Escola do município de São Paulo, entre janeiro e agosto de 2009. Os dados indicaram que, dentre as 71 mulheres incontinentes (24,6%), 44 destas (62%) referiram incontinência urinária aos esforços, 65 (91,5%) sentiam a urina escoar, 33 mulheres (46,5%) apresentavam perdas por mais de uma vez na semana e 24 (33,8%) acusaram perda urinária persistente no momento da entrevista. A gravidade, classificada como incontinência urinária moderada, foi constatada em 53 mulheres (74,7%). Os achados realçam a importância de investigações sobre incontinência urinária no período pós-parto, assim como sua abordagem no ensino e na assistência à mulher no período reprodutivo.

Prevalência de incontinência urinária autorreferida no pós-parto e fatores relacionados

OBJETIVOS: Verificar a prevalência de incontinência urinária (IU) autorreferida por mulheres no pós-parto e identificar os fatores relacionados. MÉTODOS: Estudo epidemiológico transversal, realizado no período de janeiro a agosto de 2009. Foram entrevistadas 288 mulheres com 30 dias a 6 meses de pós-parto. Os dados foram analisados estatisticamente. RESULTADOS: Observou-se prevalência de 24,6% de IU autorreferida no pós-parto. A idade média das mulheres foi de 26 anos, apenas a cor da pele apresentou diferença estatística significante, com maior representatividade em mulheres brancas. Dentre as 71 entrevistadas que referiram IU no pós-parto, a maioria era primípara e submeteu-se ao parto normal. CONCLUSÃO: A ocorrência de IU autorreferida no pós-parto associa-se à cor da pele com predominância em primíparas em comparação às não primíparas. Identificar os fatores relacionados à IU em mulheres no pós-parto e sua prevalência contribui no planejamento de atenção de enfermagem obstétrica à mulher que vivencia o período reprodutivo.

Immunohistochemical localization and quantitative assessment of GnRH-, FSH-, and LH-receptor mRNA Expression in canine skin: a powerful tool to study the pathogenesis of side effects after spaying

It has been proposed that gonadotropins and/or gonadotropin releasing hormone (GnRH) could be involved in the pathophysiology of the side effects after spaying in bitches, such as urinary incontinence and an increased production of a woolly undercoat. In order to provide tools to investigate the role of these hormones in dogs we developed immunohistochemical techniques and real-time RT-PCR to study whether GnRH-, LH-, and FSH-receptors exist in canine skin and urinary bladder. Tissue samples from the skin of the flank region and the ventral midline of the urinary bladder from euthanised dogs were examined. We were able to quantify mRNA expression of GnRH-, FSH-, and LH-receptors in canine skin and bladder biopsies with a high primer efficacy. Immunohistochemical studies showed that GnRH-, FSH-, and LH-receptors are expressed in vessel walls, the epidermis, the hair follicle and in sebaceous and sweat glands in canine skin and in transitional epithelium, and smooth muscle tissue in the urinary bladder. Our data provide the fundamentals to examine the distribution of FSH-, LH-, and GnRH-receptors in canine skin and urinary bladder and to assess gene activity at the transcriptional level by real-time RT-PCR.

Nerve-sparing open radical retropubic prostatectomy

INTRODUCTION: In recent years, the surgical technique for open radical prostatectomy has evolved and increasing attention is paid to preserving anatomic structures and the impact on outcome and quality of life. METHODS: Technical aspects of nerve-sparing open radical retropubic prostatectomy (RRP) are described. Patient selection criteria and functional results are discussed, focusing on postoperative urinary continence. RESULTS: The video demonstrates the nerve-sparing open RRP and important steps are elucidated with schematic drawings. The value of nerve sparing, not only for preserving erectile function, but also for preserving urinary continence is discussed and results from our institution are presented. In our series, urinary incontinence was present in 1 of 71 patients (1%) with attempted bilateral nerve-sparing, 11 of 322 (3%) with attempted unilateral nerve-sparing, or 19 of 139 (14%) without attempted nerve-sparing surgery. In multiple logistic regression analysis, the only statistically significant factor influencing urinary continence after open RRP was attempted nerve sparing (odds ratio, 4.77; 95% confidence interval, 2.18-10.44; p=0.0001). CONCLUSIONS: Nerve-sparing surgery has a significant impact on erectile function and urinary continence and should be performed in all patients provided radical tumour resection is not compromised. For successful nerve preservation we advocate a lateral approach to the prostate to improve visualisation and simplify separation of the neurovascular bundles from the dorsolateral prostatic capsule. Bunching, ligating, and incising Santorini's plexus over the prostate and not over the sphincter ensures a bloodless surgical field. Mucosa-to-mucosa adaptation of the reconstructed bladder neck and the urethra is another important factor to be observed.

Benign prostatic obstruction and parkinson's disease--should transurethral resection of the prostate be avoided?

PURPOSE: According to the literature transurethral resection of the prostate in patients with Parkinson's disease has an increased risk of postoperative urinary incontinence. However, this conclusion might have been reached because some patients with multiple system atrophy incorrectly diagnosed as Parkinson's disease were included in these reports. Therefore, we investigated the outcome of transurethral prostate resection in patients with a secure neurological diagnosis of Parkinson's disease. MATERIALS AND METHODS: A total of 23 patients with Parkinson's disease who underwent transurethral prostate resection for benign prostatic obstruction were evaluated retrospectively. Subsequent neurological developments in patients were followed, ensuring that those with multiple system atrophy had not been included in analysis. RESULTS: At transurethral prostate resection median patient age was 73 years, median duration of Parkinson's disease before the resection was 3 years, and median Hoehn and Yahr scale was 2. Of the 14 patients with a preoperative indwelling urinary catheter transurethral prostate resection restored voiding in 9 (64%) and only 5 (36%) required catheterization postoperatively. Of the 10 patients with preoperative urge urinary incontinence, continence was restored in 5 and improved in 3 following transurethral prostate resection. There were no cases of de novo urinary incontinence after transurethral prostate resection. At a median postoperative followup of 3 years transurethral prostate resection was successful in 16 of the 23 patients (70%). CONCLUSIONS: Transurethral prostate resection for benign prostatic obstruction in patients with Parkinson's disease may be successful in up to 70% and the risk of de novo urinary incontinence seems minimal. Thus, Parkinson's disease should no longer be considered a contraindication for transurethral prostate resection provided that preoperative investigations including urodynamic assessment indicate prostatic bladder outlet obstruction.

Alterations in the Cellular Composition of the Mouse Bladder Following Ovariectomy, Partial Bladder Outlet Obstruction, and Aging

Detrusor underactivity (DU) increases susceptibility to urinary retention and accordingly further complicates the management of urinary incontinence. Bladder muscle stretch, a lack of estrogen, and aging are 3 notable DU risk factors. The aim of this research is to better characterize the changes in cellular composition of the bladder that result from these 3 risk factors to gain a better understanding of DU pathogenesis and pathobiology. This research focuses on the effects of a lack of estrogen while also providing an outline for determining the effects of bladder muscle stretch and aging on the cellular composition of the bladder.

Mulheres motoristas de caminhão: realidades, estereótipos e desafios

Introdução A presença de mulheres no transporte rodoviário de cargas tem sido cada vez mais crescente e as repercussões do trabalho na vida das motoristas de caminhão ainda são desconhecidas pela comunidade científica. Objetivo - Caracterizar e analisar o trabalho de mulheres motoristas de caminhão e suas repercussões sobre sua saúde, a partir do relato de homens e mulheres motoristas de caminhão. Metodologia - O estudo com abordagem qualitativa utilizou a técnica do grupo focal, entrevistas individuais e observação não participante. Os grupos focais foram realizados em uma empresa transportadora localizada no estado de São Paulo e as entrevistas individuais em evento realizado na cidade de Itupeva/SP. Em oito encontros, grupos de motoristas de caminhão, discutiram a temática trabalho e saúde conduzida por meio de questões semiabertas. As mesmas questões foram utilizadas para as entrevistas individuais. Os relatos foram gravados, sendo o conteúdo das gravações transcrito e analisado por meio da metodologia Análise de Conteúdo de Bardin. A partir dos dados obtidos, construíram-se as seguintes categorias: A trajetória profissional de motoristas de caminhão; As mulheres no Transporte Rodoviário de Cargas; O trabalho; Um momento inesquecível na profissão e A saúde das mulheres motoristas na estrada. Resultados Tornar-se motorista de caminhão, para a maioria das mulheres, ocorreu por acaso, ou devido à uma necessidade financeira, ou a falta de perspectiva de emprego. Para as mulheres no Transporte Rodoviário de Cargas, o cotidiano de trabalho das profissionais está atravessado por aspectos como: a força física; dúvidas e preconceitos quanto à sua orientação sexual; o desafio em conciliar a vida dentro e fora do caminhão; conflitos na vida conjugal decorrentes da vida profissional; a discriminação sexual e a necessidade do reconhecimento no trabalho, bem como a falta de infraestrutura dedicada às trabalhadoras nas empresas e postos de parada nas rodovias brasileiras. O momento inesquecível nesta profissão, considerado por homens e mulheres, foi a primeira viagem. Os impactos do trabalho sobre a saúde das trabalhadoras recaíram sobre dores lombares e na coluna; problemas relacionados ao sono; necessidade de recorrer ao uso de drogas como anfetaminas e cocaína para manterem-se acordadas durante o trabalho; estresse; infecção urinária e uso ininterrupto de anticoncepcionais. Conclusões - A inserção das mulheres no transporte rodoviário de cargas desafia empresas e a infraestrutura existente nas rodovias do país a acompanharem as transformações sociais no mundo do trabalho, incluindo as demandas de um novo perfil de trabalhadoras. Descritores: trabalho, gênero, saúde, motoristas de caminhão.

Can group exercise programs improve health outcomes in pregnant women? A systematic review

Current scientific evidence supports the recommendation to initiate or continue the practice of physical exercise in healthy pregnant women. Group exercise programs have positive effects in improving health and well-being, as well as social support. In order to understand the scientific evidence in this field, and the outcomes in maternal health, it has generated wide interest in exploring the studies carried out with more relevant group exercise programs. The aim of this systematic review was to evaluate the available evidence on the effectiveness of group exercise programs in improving women’s and newborns health outcomes during pregnancy. Three databases were used to conduct literature searches and strict inclusion and exclusion criteria were employed. Seventeen studies were selected for analysis. All studies were randomized control trials conducted with pregnant women that evaluated the effect of group exercise programs on the health outcomes of mother and newborn. Most studies followed a supervised structured exercise program including a main aerobic part, resistance training, pelvic floor training and stretching and relaxation sections. The significant effects of the programs are related with improved maternal perception of health status, lower maternal weight gain, improved levels of maternal glucose tolerance, improved aerobic fitness and muscular strength, lower frequency of urinary incontinence, improved sick leave due to lumbopelvic pain, fewer cesarean and instrumental deliveries, higher newborn Apgar score and faster postpartum recovery. Exercise and health professionals should advise pregnant women that aerobic group exercise during pregnancy improves a wide range of health outcomes for the women and newborn

Genetic covariation of pelvic organ and elbow mobility in twins and their sisters

A range of environmental risk factors, with childbirth the most notable, have been associated with the development of pelvic organ prolapse and urinary incontinence. However, indications of genetic influence (positive family histories, ethnic differences) have prompted research into the heritability of measures of pelvic organ descent and joint mobility, which have also been associated with prolapse and incontinence. Genes appear to influence about half of the variation in these measures and, furthermore, the pelvic organ measures are associated with elbow hyperextension at a phenotypic level (r approximate to .2). We examined these measures in young, nulligravid women to determine if their association is due to a common genetic source. Data were collected from 178 Caucasian female co-twins and non-twin sisters, 50 of whom returned to be retested, which allowed reliability to be estimated and unreliable variance to be isolated in the multivariate analyses. Structural equation modeling was used to estimate genetic associations between latent elbow and bladder mobility factors for which heritabilities were estimated to be 0.80 and 0.64 respectively. The association between these factors appeared to be mediated by common genes (genetic r = .48, non-shared environmental r = -.06), with genes influencing latent elbow mobility accounting for 14% of the variation in latent bladder mobility. We speculate that genes influencing connective tissue structure may underlie this association.

Suspected hexamine intoxication in a dog

An eight-month-old Labrador Retriever was presented with urinary incontinence and haematuria. Recent history suggested that the dog had access to solid fuel hexamine tablets, ingesting a dose of 6g/kg. Clinical signs, laboratory investigation and ultrasonographic findings were supportive of chemically-induced cystitis and a diagnosis of suspected hexamine intoxication was made. The dog recovered uneventfully and it is unlikely that the insult will be carcinogenic.
