Mycoplasma genitalium and male urogenital diseases: An update / 中华男科学杂志

Mycoplasma genitalium (MG) was first isolated by Tully from the urinary tract of the male patient with non-gonococcal urethritis (NGU) in 1981. MG is extremely difficult to be cultured and was rarely studied until the development and application of molecular biology technology. The research on MG in China is still in the primary stage. However, relevant studies abroad have found that it is an important pathogen causing human genitourinary tract infection and spreading worldwide. Male MG infection is reportedly related to NGU, prostatitis, epididymitis, balanoposthitis, male HIV infection, and male infertility. This review outlines the advances in the studies of MG in male urogenital diseases.

Cuerpo extraño en uretra. Reporte de caso / Foreign body in the urethra. Report of a case

El hallazgo de cuerpo extraño uretral es una de las patologías menos comunes reportadas en la bibliografía médica y, por tanto, es de gran sorpresa para el especialista de urología. Debido a que no hay suficiente documentación, este tema despierta gran interés para el manejo futuro y en la instrucción a médicos de esta especialidad. Comúnmente, en estos casos hay un componente psicológico/psiquiátrico, sexual, autoerotismo o de abuso de sustancias psicotrópicas. De acuerdo a las características del cuerpo extraño, su localización y tipo de paciente, el tratamiento variará y su resultado final dependerá de estos factores. Presentamos el caso de un paciente varón de 52 años que acude a Emergencia con sintomatología respiratoria y dificultad urinaria de varios días de evolución, con antecedente de uso de drogas como base de cocaína y marihuana durante largo tiempo, además de prácticas sexuales grupales; se logra evidenciar de manera incidental un cuerpo extraño en la uretra. (AU)

The finding of foreign urethral body is one of the less common pathologies reported in medical literature, and therefore of great surprise to the Urology Specialist. In the absence of sufficient literature on the subject, this is an issue that arouses great interest for the future management and training doctors in this specialty. Typically, such cases have basic psychological / mental, sexual, and/or substance abuse component. According to the characteristics of the foreign body, its location and type of patient, treatment will vary and the outcome will depend on these factors; it is why a multidisciplinary assessment should be performed. We report the case of a 52-year-old male patient who came to Emergency Department with respiratory symptoms and urinary difficulty of several days duration, as background there was a history of long-term drug abuse as cocaine base and marihuana, also group sex activities; incidentally a foreign body in urethra was found.

Os achados foram organizados e categorizados, emergindo, assim, três categorias intituladas: Registro do cotidiano dos profissionais de enfermagem; Práticas cotidianas e o movimento do cuidado; e Saúde do homem: olhares e saberes. Os dados foram analisados e fundamentados na etnometodologia e na política do homem. Os resultados apontam para a importância da assistência qualificada dos profissionais de enfermagem e a valorização da política sobre saúde do homem, seu desenvolvimento contínuo em todos os níveis de atenção à saúde. Além disso, averiguou-se que é necessária a qualificação dos profissionais de enfermagem em relação à política ampliando para o ensino dos cursos de Graduação em Enfermagem. Conclui-se que a etnometodologia foi importante para a revelação dos achados e pelas pistas e indícios encontrados nos depoimentos, sendo fundamental para a interpretação dos achados obtidos nesta pesquisa.

This study is about the analysis of daily practices of nursing professionals in the human health care based on ethnomethodology. Considering the low demand of men for health services, the high incidence of chronic diseases exclusive to men, poor adherence to health services, the shame of body exposure, daily practices that are barely visible in the direction of health policy alignment of the man, the question is: is it possible to analyze the health practices to the man, in the daily activities developed by the Nursing, in the hospital space, from the PNAISH perspective? The general objective was to discuss whether the daily practices performed by nursing professionals in the health care of the man are aligned with the PNAISH. The specific objectives were to know the construction of the routine of the nursing professionals involved in the care of the man in the urology unit in the hospital context, to describe daily care practices, and to analyze the knowledge of nursing professionals in the health policy of man. The study was conducted at the urology unit of a University Hospital located in Rio de Janeiro in 2016, and the participants were the nursing professionals. This study is qualitative, ethnomethodological. The technique of data production was through a semi-structured interview and participant observation, and the treatment followed the guidance of the Bardin Content Analysis. The study was approved by the Ethics and Research Committee of UERJ receiving the number 1,582,510. The findings were organized and categorized, emerging three categories entitled Registry of the daily routine of nursing professionals; Day-to-day practices and the movement of care; and Man´s health: looks and knowledge. The data were analyzed and based on the ethnomethodology and politics of man.

Also, it was verified to qualify the nursing professionals in the policy broadening for the teaching of Nursing Undergraduate courses was important. It is concluded that ethnomethodology was important for the revelation of the findings and for the clues found in the statements, being fundamental for the interpretation of the findings obtained in this research.

Genitourinary problems in the elderly in geriatric hospitals

Population analyses and demographic data have clearly documented the rapid growth of the aging population in recent years. Although the population over 65 currently accounts for approximately 13.2% of the total population in Korea, it is estimated that this number will reach at least 40% by 2060. Aging is associated with a general decline in almost every physiological function of biological systems, including the lower urinary tract. Aging is also known to put individuals at a high risk for urinary tract infections. Geriatric hospitals in Korea have undergone a large expansion in terms of the number of beds and institutions. Many elderly patients in geriatric hospitals suffer from various genitourinary disorders. In particular, voiding dysfunction and urinary tract infections are prevalent comorbidities of other chronic geriatric diseases in patients in geriatric hospitals. Careful monitoring and management can help to reduce those genitourinary problems in elderly patients in geriatric hospitals.

Impact of autosomal dominant polycystic kidney disease on the outcomes of intracytoplasmic sperm injection in infertile males / 中华男科学杂志

<p><b>OBJECTIVE</b>To summarize the features and treatment of male infertility induced by autosomal dominant polycystic kidney disease (ADPKD), and compare the outcomes of intracytoplasmic sperm injection (ICSI) for infertile men with ADPKD and those with congenital bilateral absence of vas deferens (CBAVD).</p><p><b>METHODS</b>We retrospectively analyzed 21 cases of ADPKD-induced infertility, 15 treated by ICSI (group A), and another 164 cases of strictly matched CBAVD-induced infertility (group B). We compared the two groups in the couples' age, the number of ICSI oocytes, and the rates of fertilization, transferrable embryos, good embryos, embryos implanted, clinical pregnancy, biochemical pregnancy, early abortion, singleton and twins in the first cycle.</p><p><b>RESULTS</b>After 28 cycles of ICSI, 10 of the 15 ADPKD-induced infertility patients achieved clinical pregnancy, including 7 cases of live birth, 1 case of spontaneous abortion, and 2 cases of pregnancy maintenance. No significant differences were observed between groups A and B in the couples' age, the wives' BMI, or the numbers of ICSI oocytes and embryos transplanted (P >0.05), nor in the rates of ICSI fertilization (72.64% vs 76.17%), transferrable embryos (51.28% vs 63.24%), quality embryos (38.46% vs 49.83%), embryo implantation (17.64% vs 38.50%), abortion (0 vs 9.23%), singleton (50% vs 81.54%) and twins (50% vs 18.46%). However, the rates of clinical pregnancy (13.33% vs 42.68%, P = 0.023 <0.05) and biochemical pregnancy (13.33% vs 39.63%, P = 0.032 <0.05) were significantly lower in group A than in B.</p><p><b>CONCLUSION</b>ICSI is effective in the treatment of male infertility induced by either ADPKD or CBAVD, but the ADPKD cases have a lower success rate than the CBAVD cases in an individual cycle. The affected couples should be informed of the necessity of prenatal genetic diagnosis before embryo implantation and the inevitable vertical transmission of genetic problems to the offspring.</p>

Fosfomycin for urogenital tract infections: Advances in studies / 中华男科学杂志

Fosfomycin (FOM) is an antibiotic with a small relative molecular weight (138.1) and a long half-life, and has a unique chemical structure and antibacterial mechanisms. It exerts a bactericidal activity by inhibiting the early synthesis of bacterial cell walls. It is also a broad-spectrum antibiotic with a good drug tolerance and compliance and a low pressure to bacterial resistance, but no cross-resistance with other antibiotics. Recent studies show the effectiveness of FOM in the treatment of acute uncomplicated urinary tract infections and urogenital tract infections as well, such as prostatitis and epididymitis. This review focuses on the clinical application of FOM in the treatment of infectious diseases of the urogenital tract.

Infecciones bacterianas del tracto reproductivo masculino y su papel en la fertilidad / Bacterial infections of the male reproductive tract and their role in fertility

Antecedentes: El espermatozoide es una célula altamente especializada encargada de llevar el material genético paterno hasta el tracto reproductivo femenino en búsqueda del oocito, no obstante durante su desplazamiento puede interactuar con sustancias, otras células e incluso microorganismos que puede transportar desencadenando procesos infecciosos que alteran el éxito reproductivo. Objetivo: Describir las bacterias involucradas en la alteración de la función reproductiva y sus efectos sobre calidad espermática, así como la capacidad de los espermatozoides para transportar infecciones y diseminarlas al tracto reproductivo femenino. Resultados: Las infecciones bacterianas que afectan el tracto reproductivo masculino se clasifican en infecciones de transmisión sexual, del tracto urinario y las asociadas a la microbiota bacteriana, donde están implicadas una gran variedad de agentes etiológicos como Chlamydia trachomatis, Ureoplasma urealyticum, Mycoplasma hominis, Escherichia coli y los Staphyloccoccus coagulasa negativos. Aún es controversial el efecto de estos gérmenes sobre los parámetros seminales así como la presencia de microbiota en el semen; su diagnóstico depende de la calidad de la muestra, de la sensibilidad de la técnica de detección y de los factores de riesgo que presente el individuo. Conclusión: Los procesos inflamatorios e infecciosos en el trato reproductivo masculino influyen en la fertilidad, por lo que se requiere profundizar en el estudio de estos procesos, establecer más y mejores métodos diagnósticos y pautas para el autocuidado que disminuyan la propagación de estos agentes patógenos.

Introduction: Spermatozoon is a highly specialized cell responsible for carrying the paternal genetic material toward the oocyte. During its journey in the female reproductive tract, the sperm cell interacts with substances, cells and also microorganisms that can be transported, thus triggering infectious processes that could alter reproductive success. Objective: Describe the species of bacteria involved in the alteration of sperm cells reproductive function and their effect on the sperm quality. In addition, evaluate the ability of the sperm cell to carry infections and disseminate them in the female reproductive tract. Results: Bacterial infections that affect the male reproductive tract are classified as sexually transmitted infections, urinary tract infections, and infections associated with bacterial microbiome. Chlamydia trachomatis, Ureoplasma urealyticum, Mycoplasma hominis, Escherichia coli and coagulase-negative Staphylococcus are the main etiologic agents of these infections. The presence of bacteria in semen and their effect of in semen parameters are still controversial. To probe that bacteria are present in semen depends on the quality of the sample, the sensitivity and specificity of the detection technique and the patient risk factors. Conclusion: Inflammatory and infectious processes in the male reproductive treatment affect fertility; therefore, further study of the role of thoseprocesses, establishment of more and better diagnostic methods and guidelines for self-care to decrease the spread of these pathogens will be necessary.

Tuberculosis orchitis in patients who have undergone radical orchiectomy for testicular mass

OBJECTIVE: This study aimed to determine clinical characteristics that are associated with tuberculosis orchitis in patients who present with a testicular mass. MATERIALS AND METHODS: This is an analytic retrospective cohort study of patients who underwent radical orchiectomy for a possible testicular malignancy based on a testicular mass from 2005 to 2009. The following data were derived from a review of the patient's charts: patient age, laterality of the disease, duration of symptoms, concomitant extra-testicular tuberculosis (TB), pre-operative anti-TB treatment received, pertinent pre-operative physical findings, pertinent diagnostics done pre-operatively, and intra-operative findings. RESULTS: The prevalence of testicular tuberculosis in persons who underwent radical orchiectomy for a scrotal mass is 31.8%. TB orchitis occurs more often in younger patients, those who have had tuberculosis in the past, or have received treatment, those with larger testicular masses, those with scrotal skin sinus and tenderness or swelling, tunica, vaginalis invasion, scrotal skin invasion, and epididymal enlargement, and those with cheesy substance noted in intraoperative findings. There were no significant differences between testicular tuberculosis and testicular tumor in terms of ultrasound findings. CONCLUSION: Testicular tuberculosis is prevalent among patients who underwent radical orchiectomy due to a scrotal mass. Several clinical characteristics preoperatively and intraoperatively may predict TB orchitis in these patients.
