Confidence degree and skill development in undergraduate medical students using male urogenital training simulators / Avaliação do grau de confiança e desenvolvimento de competências em estudantes de graduação em medicina com o uso de simuladores de treinamento urogenital masculino

ABSTRACT Introduction: medical training should provide the future professional, in addition to theoretical knowledge, general and specific skills. In urology, urogenital training simulators have been presented as an ally in improving the degree of confidence and development of competencies for undergraduate medical students. Methods: exploratory descriptive research with a quantitative approach, of an experimental nature, of the randomized controlled type with cross-sectional cut. Conducted with the students of the 4th year of medicine of a Higher Education Institution in the West of Paraná. Results: 91 students attended a theoretical class with a complete explanation of the activities to be performed and answered the initial questionnaire about the degree of confidence to perform tasks in three stations with male urogenital training simulators (prostatic touch, bladder catheterization and scrotal evaluation). Of these, 45 received guidance and training with the simulators prior to the stations, while 46 should demonstrate skills directly in the three stations, mimicking patient care, only with information from the theoretical classes. The students who received previous guidance with the simulators had their scores in the development of competence higher. And, when they repeated the questionnaire about the degree of confidence to demonstrate skills with the mannequins, there was a higher degree of confidence in performing the tasks, except for the execution of a task considered more difficult. Conclusion: there was an improvement in the degree of confidence and in the development of competencies of undergraduate medical students with the orientations in the male urogenital training simulators.

RESUMO Introdução: a formação médica deve fornecer ao futuro profissional, além de conhecimentos teóricos, habilidades gerais e específicas. Na urologia, os simuladores de treinamento urogenital, têm se apresentado como aliado na melhora do grau de confiança e desenvolvimento de competências para estudantes de graduação em medicina. Métodos: pesquisa exploratória descritiva, com abordagem quantitativa, de natureza experimental, do tipo randomizado controlado com recorte transversal. Realizada com os estudantes do 4º ano de medicina de uma Instituição de Ensino Superior no Oeste do Paraná. Resultados: 91 estudantes assistiram a uma aula teórica com explanação completa das atividades a serem realizadas, e responderam ao questionário inicial sobre o grau de confiança para executar tarefas em três estações com simuladores de treinamento urogenital masculino (toque prostático, cateterismo vesical e avaliação escrotal). Destes, 45 receberam orientações e treinamento junto aos simuladores previamente as estações, enquanto 46 deveriam demonstrar habilidades diretamente nas três estações, mimetizando o atendimento ao paciente, apenas com informações das aulas teóricas. Os estudantes que receberam orientação prévia junto aos simuladores, tiveram seus escores no desenvolvimento de competência mais elevados. E, ao repetirem o questionário sobre o grau de confiança para demonstrar habilidades junto aos manequins, houve maior grau de confiança em executar as tarefas, com exceção da execução de uma tarefa considerada mais difícil. Conclusão: houve melhora no grau de confiança e no desenvolvimento de competências dos estudantes de graduação em medicina com as orientações nos simuladores de treinamento urogenital masculino.

Adherencias del capuchón del clítoris al glande: una condición poco estudiada y poco examinada / Clitoral hood adhesions to the glans penis: an understudied and under-examined condition

INTRODUCCIÓN: El clítoris es una de las estructuras vulvares menos examinadas, pese a su relevancia en la vida sexual y sus importantes relaciones anatómicas. Las adherencias del capuchón del clítoris han sido descritas y clasificadas según la exposición del glande, siendo relacionadas con trastornos del deseo sexual. La inervación del clítoris depende de raíces de S3-S4, siendo posible que síntomas frecuentes del piso pélvico tengan relación con esta condición. Realizamos un análisis retrospectivo de pacientes de policlínico de piso pélvico entre noviembre de 2021 y abril de 2022. Se incluyeron 100 pacientes con adherencias al ingreso. RESULTADOS: Promedio de edad 45,8 ± 15,5 años. Las adherencias fueron el 19% leves, el 62% moderadas y el 18% graves. Los principales síntomas eran mal vaciado vesical (38%), dolor (28%), disfunción sexual (39%) y síntomas irritativos vesicales (43%); solo una paciente fue asintomática. El área visible promedio del clítoris era de 20,7 ± 13,7 mm2. CONCLUSIONES: Las adherencias del capuchón del clítoris son un hallazgo común, muchas veces no diagnosticadas, por lo que su evaluación debe ser parte de la exploración física. Pueden asociarse a sintomatología de piso pélvico.

INTRODUCTION: The clitoris is one of the least examined vulvar structures despite its relevance in sexual life and important anatomical relationships. Clitoral hood adhesions have been described in the literature, classified based on glans exposure, and related to sexual desire disorders. The innervation of the clitoris depends on the roots of S3-S4, and frequent pelvic floor symptoms may be associated with this condition. We retrospectively analyzed the clinical record of patients admitted to a pelvic floor clinic between November 2021 and April 2022. One hundred patients with adhesions at the time of admission were registered. RESULTS: Average 45.8 ± 15.5 years. Clitoral hood adhesions were mild (19%), moderated (62%), or severe (18%). The main symptoms were voiding dysfunction symptoms (38%), pain (28%), sexual dysfunction (39%), and irritative bladder symptoms (43%); only one patient was asymptomatic. The visible area of the clitoris was 20.7 ± 13.7 mm2. CONCLUSIONS: Adhesions of the clitoral hood are often undiagnosed, and its analysis should be part of the physical exam. Clitoral hood adhesions could be associated with pelvic floor symptoms.

Impact of deep resection of endometriosis in the pelvis on urodynamic parameters

Purpose: To evaluate the effects of deep resection of endometriosis in the posterior pelvic region on urodynamic parameters. Methods: A prospective observational study conducted with female patients diagnosed with deep pelvic endometriosis before and after endometriosis resection surgery. Clinical history, image exams, the Female Lower Urinary Tract Symptoms questionnaire, urodynamic examination, cystometry, and voiding study were evaluated. Results: Patients aged 30-39 years old, operative duration of 132.5 minutes, and 2.7 days of hospital stay. Uroflowmetry and cystometry showed tendency for an increase after the surgery in the flow duration, time to maximum flow, and first voiding desire and decreased residual volume and maximum cystometric capacity. Opening, maximum urinary flow, and maximum flow pressure decreased at T1, and the closing parameters increased, although statistically non significant. The variables decreased at T1 in the urodynamic, except for detrusor overactivity. Although we observed a reasonable number of low bladder compliance and abnormal bladder sensation, the results were maintained at T1. General scores for filling and incontinence showed a significant decrease after surgery. Conclusions: A significant response in the patient's perception of urinary function was demonstrated after surgery. It is observed that the surgical procedure did not affect the uroflowmetric and cystometric characteristics of the evaluated patients.

Antioxidants Role Against Acrylamide Toxicity on Urogenital System: An Overview

@#Acrylamide (AA) is a chemical substance which is used as a soil stabilizing agent and in the production of copolymers and polymers since 1970. The presence of an AA adduct in food was observed in rats fed with fried food which led to a substantial increase in levels of hemoglobin adduct. Foods that are rich in carbohydrate when prepared at high temperature (above 120 ºC) by baking, toasting, frying, roasting or cooking results in the production of AA by the reaction of the amino acid with glucose present in it. Several studies observed AA toxicity on nervous system, reproductive system, and immune system. To justify this toxicity there is not a clear mechanism described. In this review article the mechanisms of AA toxicity on urogenital system and role of antioxidants against its toxicity has been reviewed. According to previous studies the main factor that induces AA toxicity is oxidative stress. AA treated groups revealed degeneration of the kidney’s epithelial lining and the glomerular tuft. Adverse effect on reproductive system by AA has been evidenced by sperm-head abnormalities, dominant lethal effects, and testicular epithelial tissue degeneration. Therefore, it is advised that modifying of food processing methods and consuming lot of vegetables and fruits containing antioxidants. These antioxidants give us some supports to the cells of our body organs against the AA sources which cause cell defects.

Clinical characteristics and factors influencing the prognosis of patients with mucosal melanoma / 肿瘤研究与临床

Objective:To investigate clinical characteristics and factors influencing the prognosis of patients with mucosal melanoma.Methods:The clinical data of 49 patients with mucosal melanoma in Fujian Cancer Hospital from March 2012 to March 2022 were retrospectively analyzed, and their clinical characteristics and prognostic influencing factors were observed. Kaplan‐Meier method was used for survival analysis and Cox proportional risk model was used to analyze the prognostic influencing factors.Results:Female accounted for 61.2% (30/49) of all 49 patients with mucosal melanoma and the median age was 56 years (42-79 years). The most frequent primary tumor sites occurred in head and neck (42.9%, 21/49), followed by the reproductive system (32.7%, 16/49). At the time of initial diagnosis, 81.6% (40/49) of patients had no distant metastasis and 79.6% (39/49) of patients had normal levels of peripheral blood lactate dehydrogenase. The median overall survival time of 49 patients with mucosal melanoma was 39.5 months (95% CI 23.1-55.9 months). The median overall survival time of patients without distant metastasis at the time of initial diagnosis was significantly longer than that of patients with distant metastasis [46.5 months (95% CI 31.6-61.4 months) vs. 19.2 months (95% CI 0-42.2 months, P = 0.025]. There were no statistically significant differences in median overall survival time of patients with different gender, age at the time of initial diagnosis, primary tumor site, and the level of lactate dehydrogenase in peripheral blood at the time of initial diagnosis (all P > 0.05). The presence of distant metastasis at the time of initial diagnosis was an independent risk factor for the prognosis of patients with mucosal melanoma ( HR = 0.379, 95% CI 0.157-0.918, P = 0.032). Conclusions:Mucosal melanoma is more common in female. The most frequent primary tumor sites occur in head and neck. At the time of initial diagnosis, most patients have non‐distant metastasis and the normal level of peripheral blood lactate dehydrogenase. At the time of initial diagnosis, whether there is distant metastasis is an independent influencing factor for the prognosis of patients with mucosal melanoma.

Ectopic salivary glands in the urogenital system: a case report / 中华泌尿外科杂志

The ectopic salivary gland refers to the presence of salivary gland tissue in an area other than the site where salivary glands normally exist. They often occur near the line connecting the external ear canal and the medial border of the clavicle. It is extremely rare to occur in the urogenital system. This paper retrospectively analyzed the clinicopathological data of a patient with ectopic salivary glands accidentally discovered due to testicular torsion. Patients are generally asymptomatic. If there is no fistula leading to the skin or mucosal surface, it is difficult to find clinically. The diagnosis depends on postoperative pathological examination. For ectopic salivary glands, surgery is required regardless of the location.

Arteria renal doble en Cerdocyon thous / Double Renal Artery in Cerdocyon thous

RESUMEN Objetivo. El propósito de este estudio fue explorar la duplicidad de la arteria renal en un espécimen de Cerdocyon thous, centrándose en las posibilidades de la implicación clínico-quirúrgica de esta variación anatómica. Materiales y Métodos. Fueron disecados 32 especímenes de Cerdocyon thous, obtenidos de las colecciones del Laboratorio de Enseñanza e Investigación en Morfología de los Animales Domésticos y Salvajes del Departamento de Anatomía Animal y Humana, de la Universidad Federal Rural del Rio de Janeiro y del Laboratorio de Anatomía Animal de la Universidad Federal del Pampa. Resultados. Fue observada una variación numérica en la arteria renal izquierda en un cadáver hembra adulto. El riñón izquierdo tenía dos arterias renales, una craneal y otra caudal. La primera arteria renal del riñón izquierdo, midiendo 2,25 cm de longitud, se ha originado lateralmente desde la aorta abdominal a nivel de la tercera vértebra lumbar. Además, emanaba dos ramas prehiliares, una dorsal y otra ventral, con la rama ventral suministrando también a la glándula suprarrenal. La segunda arteria renal también se ha originado lateralmente desde la aorta abdominal a nivel de la tercera vértebra lumbar, midiendo 2,36 cm de longitud. También ha emitido dos ramas prehiliares, una craneal y otra caudal, las cuales emitieron la rama uretral. Conclusiones. Las variaciones numéricas de las arterias renales deben ser consideradas en la ejecución de procedimientos quirúrgicos, radiológicos y experimentales, con los fines de evitar errores ocasionados por la falta de conocimiento de la posibilidad de estas variaciones tanto en animales domésticos como salvajes.

ABSTRACT Objective. The aim of this study was explored the duplicity of renal artery in a specimen of Cerdocyon thous, focusing on the possibilities of clinical-surgical implication of this anatomical variation. Materials and methods. Were dissected 32 specimens of Cerdocyon thous, obtained from the collections of the Laboratório de Ensino e Pesquisa em Morfologia dos Animais Domésticos e Selvagens do Departamento de Anatomia Animal e Humana, da Universidade Federal Rural do Rio de Janeiro e Laboratório de Anatomia Animal da Universidade Federal do Pampa. Results. Were observed a numerical variation in the left renal artery in an adult female cadaver. The left kidney had two renal arteries, one cranial and another caudal. The first renal artery of the left kidney, measuring 2.25 cm in length, originated laterally from the abdominal aorta at the level of the third lumbar vertebra. Moreover, it emanated two pre-hilar branches, one dorsal and one ventral, with the ventral branch supplying also to the adrenal gland. The second renal artery also originated laterally from the abdominal aorta at the level of the third lumbar vertebra and measured 2.36 cm in length. It also emitted two pre-hilar branches, one cranial and another caudal, which emitted the ureteral branch. Conclusions. Numerical variations of the renal arteries should be considered in the execution of surgical, radiological and experimental procedures in order to avoid mistakes made due to lack of knowledge of the possibility these variations both in domestic and wild animals.

The reason for consultation is usually genital bleeding and/or dysuria. The treatment includes from conservative therapy to surgical interventions.We present the case of an 11-year-old white girl who came to the Emergency Room due to vaginal discharge for 6 days and genital bleeding for 3 days that was accompanied by stabbing pain in genital region, with occasional dysuria. A circular eversion of the urethral mucosa was observed, so the patient was surgically intervened, performing a prolapse resection with clinical resolution

Evaluación de la eficacia de dos terapias estrogénicas locales más un lubricante vaginal, para el control de los síntomas del síndrome genitourinario de la menopausia

Objetivo: Evaluar la eficacia de dos terapias estrogénicas locales más un lubricante vaginal (K-Y gel), para el control de los síntomas del síndrome genitourinario de la menopausia. Materiales y métodos: Ensayo clínico, aleatorizado, prospectivo y controlado, no enmascarado. Se incluyeron 57 mujeres posmenopáusicas atendidas en la consulta de climaterio, entre julio de 2014 y julio de 2016. Se asignaron dos grupos aleatorizados: grupo A (30 mujeres recibieron 0.625 mg intravaginales de estrógenos equinos conjugados dos veces a la semana), y grupo B (27 mujeres recibieron 0,5 mg intravaginales de estriol dos veces a la semana) durante seis meses. Ambos grupos recibieron, adicional a la terapia hormonal, 5 gramos intravaginales del lubricante cada 6 horas. A todas las mujeres, para evaluar el estatus hormonal, antes del inicio y a los seis meses, se les determinó el índice de maduración vaginal, y mensualmente se les evaluaba la mejoría de la sintomatología del síndrome genitourinario de la menopausia, además de calcularles el índice de salud vaginal. Resultados: La edad promedio del grupo fue de 58,03±4,85 años. Se observó una significativa disminución en los síntomas en el grupo B, comparado con el grupo A (p<0,001), al mes (p<0,001) y a los 6 meses de seguimiento (p=0,018). El tiempo para lograr una mejor puntuación en el índice de salud vaginal, fue significativamente menor en el grupo B. Al final de la investigación, la evaluación de los cambios en el índice de maduración vaginal, mostró un aumento en las células superficiales e intermedias, en el grupo B, superior al grupo A, mientras se reportó mayor disminución en el porcentaje de células parabasales del grupo B. Las mujeres del grupo A mostraron una reducción en la sintomatología, al final del estudio, del 72% frente al 87% del grupo B. Conclusiones: El uso de la terapia estrogénica local, en el síndrome genitourinario de la menopausia, a los seis meses de seguimiento, pone de manifiesto una mejoría significativa de los síntomas. El uso de estriol más lubricante, se asoció con mejores resultados y menores efectos adversos, en comparación con los estrógenos equinos conjugados más lubricante.

Objective. To evaluate the efficacy of the combination of two local estrogenic therapies with a vaginal lubricant (K-Y gel), to control the symptoms of the severe atrophic vulvovaginitis. Materials and methods. Prospective, controlled and randomized study. Fifty-seven postmenopausal women treated by the author in the climacteric consultation, between July 2014 and July 2016 were included. Two groups were established, 30 women received twice a week 0.625 mg intrava-ginal conjugated equine estrogens (group A), and 27 Women received twice a week during six months Estriol at doses of 0.5 mg intravaginal (group B). Both groups received, in addition to the hormonal therapy, 5 grams of intravaginal lubricant every 6 hours. In order to evaluate the hormonal status of all women, before starting and six months later, their vaginal maturity index was determined, simultaneously, the vaginal health index was calculated monthly in each control. Results. The women of group A showed a symptoms reduction, at the end of the study, of 72% compared to 87% of group B. None of the women presented complications related to therapy. Conclusions. The use of local estrogen therapy, in severe atrophic vulvovaginitis, is a well-tolerated measure; after six months of monitoring, a significant improvement of the symptoms and the vaginal health index is evidenced. The use of estriol with lubricant was associated with better results and less adverse effects, compared to conjugated equine estrogens and lubricant; however, the rates of sexual satisfaction were similar.

Updated treatment guideline for hormone therapy in postmenopausal women

Since menopause hormone therapy was first introduced, it has been widely used worldwide as the most effective treatment for vasomotor symptoms in menopausal women and for genitourinary syndrome of menopause. Menopause hormone therapy has been shown to prevent bone loss and fracture, but it may additionally offer various benefits for numerous other symptoms. The benefit-to-risk ratio of menopause hormone therapy is most favorable for women aged younger than 60 years or who are within 10 years of menopause onset and have no contraindications. Longer durations of therapy should be limited to patients with documented indications, such as persistent vasomotor symptoms or bone loss. For genitourinary syndrome of menopause, low-dose vaginal estrogen therapy or other therapies are recommended. Tibolone is a synthetic steroid that provides a therapeutic effect in the treatment of menopausal symptoms.

Ultrasound-guided genitourinary interventions: principles and techniques

Ultrasound (US) is often used to guide various interventional procedures in the genitourinary (GU) tract because it can provide real-time imaging without any radiation hazard. Moreover, US can clearly visualize the pathway of an aspiration or biopsy needle to ensure the safety of the intervention. US guidance also helps clinicians to access lesions via the transabdominal, transhepatic, transvaginal, transrectal, and transperineal routes. Hence, US-guided procedures are useful for radiologists who wish to perform GU interventions. However, US-guided procedures and interventions are difficult for beginners because they involve a steep initial learning curve. The purpose of this review is to describe the basic principles and techniques of US-guided GU interventions.

Transcorporal artificial urinary sphincter in radiated and non - radiated compromised urethra. Assessment with a minimum 2 year follow-up

ABSTRACT Purpose to assess the efficacy of transcorporal artificial urinary sphincter (AUS) implantation on continence for male stress urinary incontinence in cases of prior surgical treatment or/and radiation failure, and as a first option in radiation patients. Materials and Methods From March 2007 to August 2012, 37 male patients were treated with transcorporal AUS AMS™ 800. Twelve patients had primary placement of transcorporal cuff, a surgical option due to a previous history of radiation and 25 patients had secondary procedure after failure of AUS or urinary incontinence surgery. Functional urinary outcomes were assessed by daily pad use, 24-hour Pad-test and ICIQ-SF questionnaire. Quality of life and satisfaction were assessed based on I-QoL and PGI-I questionnaires. Results After a median of 32 months, the continence rate (0 to 1 pad) was 69.7%. Median pad test was 17.5g (0-159), mean ICIQ-SF score was 7.3/21 (±5.4) and mean I-QoL score was 93.9/110. A total of 88% of the patients reported satisfaction with the AUS. The 5-year actuarial revision-free for AUS total device was 51%. Patients for primary implant for radiation were not more likely to experience revision than non-radiation patients. Preservation of erections was reported in half of the potent patients. Conclusions Transcorporal AUS cuff placement is a useful alternative procedure option for severe male UI treatment, especially in patients with a compromised urethra after prior surgery or radiation. A high continence rate was reported and implantation as first option in radiation patients should be considered.

Should oncological cases of upper urinary system be excluded at the beginning of the laparoscopic learning curve?

ABSTRACTPurpose:The place of oncological cases of upper urinary system in the laparoscopic learning curve was investigated.Materials and Methods:A total of 139 patients from two different centers underwent laparoscopic operations and were included in this retrospective study.Results:Mean operative times for oncological, and non-oncological cases were 101.3 (range 60-450), and 102.7 (45-490) minutes respectively. Fourty-two (31.3 %) patients were oncological cases. In 4 oncological cases, the surgeons switched to open surgery because of massive bleeding and six (14.2 %) oncological cases required blood transfusions during peri/postoperative periods. Pulmonary embolism was observed in one oncological case. In one non-oncological case, the surgeon switched to open surgery because of intestinal perforation and 10 (9.7 %) non-oncological cases needed blood transfusions during peri/postoperative periods. In addition, some complications such as intestinal perforation (n=1), mechanical ileus (n=1), and pulmonary embolism (n=1) were observed during postoperative period. Intestinal perforation was repaired using laparoscopic (n=1) method. Mechanical ileus was approached with open surgical technique. Mean hospital stay of the patients in the oncological and non-oncological series were 4.5 (3-23) and 4.5 (3-30) days respectively.Conclusion:We think that renal oncological cases should be included in the spectrum of laparoscopic indications even at the beginning of the learning curve. Certainly, we still share the opinion that cancer cases which require highly challenging surgeries like radical cystectomy, and prostatectomy should be postponed till to gaining of higher level of experience.

Isolation and antimicrobial resistance of Mycoplasma from urogenital tract / 中国感染控制杂志

Objective To explore the isolation and antimicrobial susceptibility of Mycoplasma from urogenital tract,and provide the basis for rational clinical treatment.Methods Urogenital tract specimens from 57 904 outpa-tients in a hospital between 2008 and 2014 were performedUreaplasma urealyticum (Uu)and Mycoplasma hominis (Mh)culture,identification,and antimicrobial susceptibility testing.Results Of 57 904 patients with urogenital in-fection,21 614 (37.33%)had positive culture for Mycoplasma,isolation rate of Mycoplasma in female and male were 42.14% (18 917/44 889)and 20.72% (2 697/13 015 )respectively;Mycoplasma was mainly isolated from population of 21 -40 years old;Uu≥104 CFU/mL and Mh<104 CFU/mL mixed infection was common(69.35%). The resistance of Mycoplasma to doxycycline,josamycin,and tetracycline were all low(<10%);resistance rates of Mh to doxycycline,erythromycin,clarithromycin,and roxithromycin were all significantly higher than Uu (all P <0.05).Conclusion Mycoplasma infection/carriage rate in female outpatients is significantly higher than male outpa-tients,antimicrobial profile of Uu is different from Mh,josamycin and doxycycline can be as the first choice for treatment of non-gonococcal urethritis (cervicitis)caused by Mycoplasma.

Direction of new drug R&D in Chinese materia medica over therapeutic field of new drugs approved by CFDA during 2010-2014 / 中草药

To provide the reference for selecting the research and development trend and direction of new drug in Chinese materia medica (CMM). We sorted out the new drugs of CMM approved by the China Food and Drug Administration (CFDA) during 2010-2014 through database retrieval, analyzed their indications, declared period and approval rates, then discuss and suggest the predominance of CMM for research and development. In recent five years, among the new drugs of CMM approved by CFDA, their main indications are those for cardiovascular system, respiratory system, and urogenital system. The declared period from short to long is gynaecology system, respiratory system, and urogenital system. From the point of approval rates, urogential system and pediatric system are higher than others. Comprehensive the above three factors, we get that cardiovascular system is a classic indication for CMM; Urogenital system, pediatrics system and gynecologic system will be the potential fields for CMM research and development.

Penile Fracture: Our Experience in a Tertiary Care Hospital

PURPOSE: Penile fracture is rare, but it is a urological emergency that always requires immediate attention. Moreover, penile fracture has been reported more frequently in recent years. It may have devastating physical, functional, and psychological consequences if not properly managed in time. MATERIALS AND METHODS: The objective of this study was to highlight the causes, clinical presentation, and outcomes of cases of penile fracture. This was a prospective observational study extending from November 2012 to November 2014. Each patient underwent a thorough clinical evaluation and received proper treatment. RESULTS: Twenty patients with penile fracture, aged 19 to 56 years (mean, 28 years) were evaluated in this study. Vaginal intercourse was the most common mechanism of injury. Most of the patients (95%) were diagnosed clinically with a proper history and clinical examination. Nineteen patients were treated surgically. The patients underwent six months of follow-up, and were evaluated with local examinations, questionnaires, and colour Doppler ultrasonography as necessary. CONCLUSIONS: Although penile fracture is an under-reported urological emergency, its incidence is increasing. It is usually diagnosed based on a clinical examination, but ultrasonography can be very helpful in diagnosis. Especially in cases where treatment is delayed, surgery is preferable to conservative management, because it is associated with better outcomes and fewer long-term complications.

Age-dependent expression of Pten and Smad4 genes in the urogenital system of Wistar rats

PURPOSE: To analyze Pten and Smad4 gene expression in the urogenital system of Wistar rats in differents ages. METHODS: Pten and Smad4 mRNA expression was assessed in the bladder, ventral prostate, testis, ovaries, and uterus by real-time PCR. Statistical analysis using the ANOVA (p<0.05). RESULTS: Pten levels showed a progressive age-dependent increase in the bladder (male and female) and prostate and were elevated in the ovaries of the middle-aged. In the uterus, no statistically significant differences were observed; in the testis, increased and decreased levels were seen in young adult and middle-aged rats, respectively. Smad4 expression was downregulated in the ovaries of the pubertal group but increased in the middle age group. In the uterus, Smad4 expression in the oldest group was higher than the others groups. In the testis, Smad4 expression steadily declined with age; in the prostate, it was higher in middle-aged rats than in younger rats. A similar trend was observed in the bladder of male and female middle-aged rats, compared with the pubertal group. CONCLUSION: The changes in phosphatase tensin homologue and Smad4 mRNA expression in Wistar rats appear to be associated with hormonal modifications in puberty and may be related to early follicular and testicular development. .

Biapenem in treatment of respiratory and urinary bacterial tnfections: A multicenter, randomized, controlled clinical trial / 第二军医大学学报

Objective To evaluate the efficacy and safety of biapenem in treatment of bacterial infections of the respiratory and urinary systems. Methods A total of 288 patients with infections of the respiratory and urinary system were included in this multicenter, blinded, randomized, and parallel controlled trial. The patients were randomly assigned to receive biapenem (experimental group, n = 144) ormeropenem (control group, n = 144). Results The clinical curative rates of the experimental group and control group were 95. 10% (136/143) and 92. 25% (131/142), respectively, with those for respiratory system infection being 93. 06%(67/72) and 94. 29% (66/70) and those for urinary infection being 97. 18% (69/71) and 90. 28% (65/ 72), respectively. The bacterial eradication rates in the experimental group and control group were 88. 00% (66/75) and 92.65%(63/68), respectively, with those for the respiratory infectionbeing 83. 33% (30/36) and 90. 62% (29/32) and those for urinary infection being 92. 31% (36/39) and 94. 44% (34/36), respectively. There were no significant differences between the two groups regarding the clinical curative rates or bacterial eradication rates (P>0. 05). The side-effect rate was 2. 08%(3/ 144) in the experimental group and 8. 33% (12/144) in the control group, with significant differences found between the two groups (P = 0. 030 6). Conclusion Compared to meropenem, biapenem has similar efficacy in treatment of respiratory and urinary system infection, but with study.

Dibutyl phthalate influences the secretion of rat ovarian granulose cells / 中国组织工程研究

BACKGROUND:Studies have shown that dibutyl phthalate has certain toxicity to the reproductive system of male animals. OBJECTIVE:To investigate the effects of dibutyl phthalate on secretion of rat ovarian granulose cells. METHODS:Ovarian granulosa cells from 25-day-old female Sprague-Dawley rats were cultured in vitro and exposed to different concentrations of dibutyl phthalate (0, 5, 20, 80μmol/L) for 24 hours. Estradiol and progesterone in ovarian granulosa cells were measured by the method of radio-immunity. Expression of the cytochrome P450aromatase and P450 side chain cleavage enzyme mRNA in granulosa cells were examined by real-time PCR. RESULTS AND CONCLUSION:The levels of estradiol and progesterone in granulosa cells decreased after exposure to dibutyl phthalate. With the increase of the dibutyl phthalate concentration, the expression of P450arom and P450scc mRNA decreased gradual y. Dibutyl phthalate could induce reproductive dysfunction and toxicity to female rats.
