Influencia de la modalidad de respuesta, edad y nivel de educación en el cuestionario internacional de síntomas prostáticos (IPSS) / Influence of the response modality, age and level of education in the international prostate symptoms questionnaire (IPSS)

OBJETIVOS: evaluar la influencia de la modalidad de respuesta (paciente vs. asistido por urólogo) en el cuestionario IPSS (International Prostate Symptom Score) y su relación con la edad y nivel de educación. MATERIALES Y MÉTODOS: Análisis prospectivo de 74 pacientes que acudieron a la consulta de urología por síntomas de Hiperplasia Prostática Benigna (HPB) con o sin tratamiento para su patología y que no hayan completado anteriormente el cuestionario internacional de síntomas prostáticos (IPSS). Los cuestionarios fueron completados en la misma consulta urológica, primero por el paciente y luego con ayuda del urólogo. Se categorizó por edad y nivel de educación. Se evaluó la diferencia entre los puntajes de IPSS obtenidos con la forma autocompletada y con asistencia del urólogo y si esta diferencia estaba relacionada con la edad y con el nivel de educación. Los datos fueron analizados utilizando test no paramétrico para datos apareados de Wilcoxon. RESULTADOS: no se encontró diferencia estadísticamente significativa entre el cuestionario completado por el paciente y el asistido por el urólogo. La media del score total fue de 13,66, y 13,67, respectivamente (p: 0.86). Al analizar los subgrupos, con respecto a la edad y al nivel de educación, tampoco se encontraron diferencias estadísticamente significativas. CONCLUSIÓN: en nuestra población de estudio, el cuestionario IPSS no fue influenciado por la modalidad de administración, tampoco por la edad ni por el nivel de educación.

OBJECTIVES: to evaluate the influence of the response modality (patient vs. urologist-assisted) in the IPSS questionnaire (international prostate symptom score) and its relationship with age and education level. MATERIALS AND METHODS: Prospective analysis of 74 patients who came to the urology clinic for symptoms of Benign Prostatic Hyperplasia (BPH) with or without treatment for their pathology and who have not previously completed the international prostate symptoms questionnaire (IPSS). The questionnaires were completed in the same urological consultation, first by the patient and then with the help of the urologist. It was categorized by age and education level. The difference between the IPSS scores obtained with the self-completed form and with the assistance of the urologist and whether this difference was related to age and level of education was evaluated. The data were analyzed using non-parametric test for paired Wilcoxon data. RESULTS: no statistically significant difference was found between the questionnaire completed by the patient and the one assisted by the urologist. The average of the total score was 13.66, and 13.67, respectively (p: 0.86). When analyzing the subgroups, regarding age and level of education, no statistically significant differences were found. CONCLUSION: In our study population, the IPSS questionnaire was not influenced by the modality of administration, neither by age nor by level of education.

Hepato-pancreatico-biliary surgical education: rediscovery of cadaver based teaching

Background: As the classical surgical training (mentor–trainee) model is not feasible in the current era of surgical training and simulation model for training young residents is proven, the advanced surgical residents may benefit from cadaver based surgical teaching.Methods: International Hepato-Pancreato-Biliary Association India 2017 provided great opportunity to organize basic hepato-pancreatico-biliary (HPB) anatomy workshop clubbed with HPB radiology and other advanced surgical techniques. It was attended by advanced surgical residents and practicing junior faculty. Post-program survey was conducted and results implied.Results: 131 surgeons attended and 90 (80% residents, 15.6% practicing surgeons) completed the survey. Majority (97.5%) felt that the HPB anatomy was adequately demonstrated by spending enough time for dissection techniques and discussion. Most (84.7%) never attended cadaveric dissection during or after their training program. 95.1% think that dedicated anatomy or dissection teaching sessions are either very useful or useful for their level of surgical training. All participants found cadaveric workshop either very useful (73.3%) or useful (26.7%) learning tool. Majority (73.3%) felt that demonstrated HPB procedures were appropriate for their level. All participants (100%) felt that cadaveric workshops will improve their surgical skills and many (93.4%) felt these improve their confidence in operation theatres.Conclusions: This cadaver based HPB teaching program is an initial step for unique HPB surgical education and useful adjunct for advanced surgical trainees in modern era. Residents consider this as good learning tool and possibly improve surgical skills and confidence. The translation of cadaver based HPB surgical learning into better surgical care needs evaluation in future.

Efeitos cistométricos da castração hormonal e administração diária de tadalafila emcamundongos com hiperatividade detrusora induzida pela deficiência crônica de óxido nítrico

Sintomas do trato urinário inferior (STUI) representam uma das queixas mais comuns em homens. Diferentes distúrbios da micção podem resultar em STUI. Hipogonadismo é umadoença comum e subdiagnosticada no idoso, podendo estar associado a STUI.

Administração de toxina botulínica A e a orquiectomia no tratamento da hiperplasia prostática benigna do cão / Botulinum toxin A administration and orchiectomy in the treatment of canine benign prostatic hyperplasia

A fisiopatologia da hiperplasia prostática benigna (HPB) não está totalmente compreendida, no entanto, a diidrotestosterona é o principal hormônio envolvido. Recentemente, o efeito da toxina botulínica A (TB-A) foi investigado, mostrando que esta induz atrofia do parênquima e redução do volume prostático. Com base nisso, este estudo teve como objetivos comparar os efeitos da administração da TB-A com a orquiectomia no tratamento da HPB, além de avaliar os efeitos da TB-A sobre a libido e qualidade do sêmen. Para tanto, 16 cães adultos foram submetidos à castração ou administração de 500U de TB-A, e avaliados durante 16 semanas. A orquiectomia mostrou-se um excelente tratamento, promovendo redução de 80% do volume prostático. Aplicação da TB-A não ocasionou alterações na libido, ereção ou qualidade e características seminais. Por outro lado, reduziu significamente o volume da próstata. Os resultados sugerem que a administração intraprostática de TB-A é um tratamento alternativo efetivo e sem efeitos colaterais para cães destinados a programas de reprodução. No entanto, esta terapia apresenta reduções inferiores do volume prostático, quando comparada com a orquiectomia.

The pathogenesis of benign prostatic hyperplasia (BPH) is not completely known, however, dihydrotestosterone is a hormone involved in enlargement of the prostate. Recently, the effect of botulinum toxin A (BT-A) was investigated and has shown to induce atrophy of the gland. Based on that, the aims of this study were to compare the effects of administration of BT-A with orchiectomy in the treatment of BPH, in addition to assessing the effects of BT-A on libido and semen quality. Therefore, 16 sexually intact male dogs were submitted to orchiectomy or administration of 500U BT-A, and evaluated for 16 weeks. Orchiectomy presented excellent results, reducing the prostate volume up to 80%. Administration of BT-A did not interfered on libido, erection or semen characteristics. On the other hand, reduced significantly the prostate volume. The results suggest that intraprostatic injection of BT-A is an effective alternative treatment without adverse effects for valuable breeding dogs with BPH. However, this therapy showed lower reduction of prostate volume when compared to orchiectomy.

Introducción: el D-004, un extracto lipídico del fruto de la palma real, Roystonea regia, constituido por una mezcla reproducible de ácidos grasos, principalmente oleico, palmítico, láurico y mirístico, ha mostrado prevenir la hiperplasia prostática (HP) inducida con T en roedores y actúa mediante un mecanismo multifactorial que implica la inhibición de 5a-reductasa prostática, el antagonismo de las respuestas mediadas por los a1-ADR, efectos anti-inflamatorios y antioxidantes. Objetivo: el presente trabajo tiene como propósito resumir los resultados parciales (18 meses) del estudio de carcinogenicidad a largo plazo del D-004 en ratas, el cual culminará con el tiempo establecido de 24 meses. Métodos: se distribuyeron ratas Sprague Dawley (SD) de ambos sexos aleatoriamente, en cuatro grupos (50 ratas/sexo/grupo): un grupo como control de vehículo, y tres tratados con D-004 (500, 1 000 y 1 500 mg/kg, respectivamente). Los tratamientos se administraron por intubación gástrica. Este reporte incluye los resultados de peso corporal, observaciones clínicas, mortalidad y frecuencia de aparición de tumores hasta ese momento. Resultados: la frecuencia de mortalidad es baja, en los grupos tratados fue de un 8.3 por ciento por un 9 por ciento en los controles, no se evidencia disminución en el tiempo de supervivencia y las observaciones diarias no revelaron signos indicativos de toxicidad atribuibles al tratamiento. Además, el momento de aparición y la frecuencia de tumores en animales tratados y controles fueron estadísticamente similares en ambos sexos. Conclusiones: en conclusión, la administración de D-004 (5001500 mg/kg) a ratas durante los primeros 18 meses del estudio, no mostró evidencias de toxicidad o carcinogenicidad temprana relacionadas con el tratamiento

Introduction: D-004, a lipid extract from royal palm (Roystonea regia) fruit made up of a reproducible mixture of fatty acids, mainly oleic, palmitic, lauric and myristic, has shown to prevent prostate hyperplasia (PH) induced by T in rodents. It acts through a multifactorial mechanism involving prostatic 5a-reductase inhibition, antagonism of a1-ADR-mediated responses, and antiinflammatory and antioxidant effects. Objective: the paper is aimed at summarizing the partial results (18 months) of the long-term carcinogenicity study of D-004 in rats, which is set to conclude in the established 24-month period. Method: Sprague Dawley (SD) rats of both sexes were randomly distributed into four groups (50 rats/sex/group): one group as vehicle control and three treated with D-004 (500, 1 000 and 1 500 mg/kg, respectively). Treatments were administered by gastric intubation. This report presents the results obtained so far concerning body weight, clinical observations, mortality and frequency of appearance of tumors. Results: mortality rate is low: 8.3 percent in the treated groups and 9 percent among controls. No evidence was found of survival time reduction, and daily observations did not reveal any signs of toxicity attributable to the treatment. The time of appearance and the frequency of tumors in treated animals and controls were statistically similar in both sexes. Conclusions: administration of D-004 (5001 500 mg/kg) to rats during the first 18 months of the study did not show any evidence of early carcinogenicity or toxicity associated with the treatment

Métodos de diagnóstico para detecção de prostatopatias caninas / Canine prostatic disease: diagnosis methods

As doenças prostáticas são comuns em cães, desenvolvendo-se após a maturidade sexual. Entre as afecções que acometem a próstata desses animais, a mais frequente é a hiperplasia prostática benigna (HPB). As neoplasias prostáticas, apesar de menos frequentes, são altamente malignas e um diagnóstico tardio está associado a um prognóstico ruim. Os principais métodos de diagnóstico das enfermidades prostáticas em cães incluem um exame clínico detalhado, ultrassonografia, punção aspirativa e biópsia. A utilização de biomarcadores séricos vem sendo estudada como uma maneira de se detectar a doença precocemente, evitando possíveis complicações no quadro clínico dos pacientes. Assim, estudos visando ao diagnóstico precoce de prostatopatias caninas, especialmente o câncer prostático, são cruciais para um tratamento eficaz e melhora da qualidade de vida do animal acometido.

Prostatic diseases are common in older dogs, developing after sexual maturity. The most common affecting canine prostate is benign prostatic hyperplasia (BPH). Although less frequent, prostatic neoplasias are highly malignant, and a late diagnosis is closely associated with a poor prognosis. The main methods of diagnosis of the canine prostatic disease include a detailed clinical exam, ultrasound, prostatic fine-needle aspirate and biopsy. Studies towards early diagnosis of this condition are crucial for effective treatment and improvement of quality of life of affected animals. The use of biomarkers has been studied for early detection of the disease, avoiding possible complications in clinical patients.

El objetivo de este trabajo prospectivo es determinar la eficacia del método KTP-láser de 80 watt para la vaporización y ablación de la HPB sintomática. También se analizan los resultados al combinar el KTP-láser con la RTU-P y su repercusión sobre la hemoglobina. Material y Método: 300 pacientes con HPB sintomática fueron tratados entre agosto del 2004 y noviembre del 2006 con el KTPláser o combinado con RTU-P. La resección adicional fue efectuada en pacientes con adenomas grandes o por lóbulo medio acentuado. El efecto ablativo fue controlado al final de la operación por medio de TRUS. Resultados: 300 pacientes fueron tratados en 2 grupos. El grupo 1 (n: 50) con sólo tratamiento láser y pequeños adenomas, la hemoglobina se redujo un 3,2 por ciento y nadie requirió una transfusión. El grupo 2 (n: 250) con tratamiento combinado de KTP-láser y RTU-P en adenomas grandes, la hemoglobina se redujo en promedio 15,2 por ciento después de la intervención; 2 pacientes (0,8 por ciento) necesitaron una transfusión. Conclusión: El estudio pone de manifiesto, las ventajas de combinar ambos procedimientos quirúrgicos para obtener un mejor resultado en la ablación del adenoma sobre todo en próstatas de gran tamaño.
