Síndrome de Herlyn-Werner Wünderlich: reporte de dos casos / Herlyn-Werner-Wünderlich syndrome: Two case report

El síndrome de Herlyn-Werner Wünderlich, también llamado OHVIRA por sus siglas en inglés (obstructed hemivagina and ipsilateral renal anomaly), es una anomalía congénita mülleriana poco frecuente que se caracteriza por la asociación entre útero didelfo, hemivagina obstruida y agenesia renal ipsilateral. La presentación clínica más común es la masa abdominal secundaria a hematocolpos, dolor y dismenorrea. Se asocia a infertilidad, endometriosis, alteraciones menstruales y obstétricas. La ecografía es la técnica de elección para la evaluación inicial, mientras que la resonancia magnética sigue siendo el método más exacto para el diagnóstico. La septotomía vaginal es el tratamiento recomendado. Se describen 2 casos clínicos con el objetivo de destacar la importancia del diagnóstico temprano para evitar las posibles complicaciones futuras.

Herlyn-Werner-Wunderlich syndrome, also known as obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), is a rare, congenital Müllerian duct anomaly characterized by the association of septate uterus, obstructed hemivagina, and ipsilateral renal agenesis. The most common clinical presentation is an abdominal mass secondary to hematocolpos, pain, and dysmenorrhea. It is associated with infertility, endometriosis, and menstrual and obstetric alterations. The ultrasound is the technique of choice for the initial assessment, while the magnetic resonance imaging remains the most accurate method for diagnosis. The resection of the vaginal septum is the recommended treatment. Here we describe 2 clinical cases to highlight the importance of an early diagnosis to prevent potential complications in the future.

Introduction. The male genital exam is a simple and quick assessment to look for urogenital disease. Data on the prevalence of urogenital disease in male adolescents are limited. Our objective was to describe the prevalence of urogenital disease in male adolescents. Population and methods. Descriptive, cross-sectional study conducted at the Department of Adolescenceof a public hospital in the City of Buenos Aires. The medical records of male patients aged 9 to 20 years seen between 2008 and 2018 were retrospectively reviewed; all those with a genital exam were included. Data on age, pubertal stage, orchidometry, and urogenital disease before adolescence and at the time of consultation were recorded. The prevalence was described as percentage and 95% confidence interval (CI).As per estimations, 1167 medical records had to be included to establish the population sample. Results. A total of 2129 medical records were assessed and 1429 were included. No genital exam had been conducted in 686 cases. The median age of the population was 12 years (interquartile range: 11­14 years). Urogenital disease before adolescence was detected in 72 boys (5.7%; 95% CI: 4.5­7.2). Urogenital disease was found in 272 adolescents (14.8%; 95% CI: 13.1­16.7); the most common conditions were balanopreputial adhesions in 5.3% (95% CI: 4.2­6.6), varicocele in 2.7% (95% CI: 2­3.7), and phimosis in 1.8% (95% CI: 1.2­2.6). Conclusions. A genital exam allowed to detect that 14.8% of adolescent boys had a urogenital diseaseThe most common conditions were balanopreputial adhesions, varicocele, and phimosis.

Delphi Consensus on Diagnostic Criteria for LUMBAR Syndrome.

OBJECTIVE: To develop consensus on diagnostic criteria for LUMBAR syndrome, the association of segmental infantile hemangiomas that affect the Lower body with Urogenital anomalies, Ulceration, spinal cord Malformations, Bony defects, Anorectal malformations, Arterial anomalies and/or Renal anomalies. STUDY DESIGN: These diagnostic criteria were developed by an expert multidisciplinary and multi-institutional team based on analysis of peer-reviewed data, followed by electronic-Delphi consensus of a panel of 61 international pediatric specialists. RESULTS: After 2 Delphi rounds, a 92% or higher level of agreement was reached for each Delphi statement. 98% of panelists agreed with the diagnostic criteria, and 100% agreed the criteria would be useful in clinical practice. The diagnosis of LUMBAR requires the presence of a segmental, or patterned, infantile hemangioma of the lumbosacral, sacrococcygeal, or pelvic cutaneous regions plus one additional criterion of the urogenital, spinal, bony, anorectal, arterial, or renal organ systems. CONCLUSIONS: These diagnostic criteria will enhance clinical care by improving screening, detection, and overall awareness of this poorly understood neurocutaneous disorder. The criteria can be utilized by a wide variety of pediatric subspecialists. In addition, formal criteria will improve phenotypic uniformity among LUMBAR syndrome cohorts and a patient registry, allowing investigators to assess clinical features, long-term outcomes, and results of genetic sequencing in a standardized manner. Finally, these criteria will serve as a starting point for prospective studies to establish formal screening and management guidelines.

Characterization of Escherichia coli Isolated from Sows Presenting Purulent Vulvar Discharge.

Purulent vulvar discharge is a clinical sign of genitourinary tract infections, which are a significant concern in swine facilities, leading to sow culling and mortality. Escherichia coli is one of the main agents involved in these diseases. This study aimed to characterize the virulence and antimicrobial resistance profiles as well as the phylotype of Escherichia coli strains isolated from sows with purulent vulvar discharge. The results showed that at least 2 of the 29 tested virulence genes related to extraintestinal pathogenic E. coli were present in all strains tested. The most frequent gene was iutA, present in all strains, followed by the genes iucD, csgA, iss2, and irp2. Associations between iron uptake genes, genes related to adhesion, attachment, and serum resistance, as well as genes related to toxin release and bacteriocin, were frequent. The most prevalent phylotype was B1 (40.0%), followed by A (18.5%), D (11.9%), C (9.6%), B2 (7.4%), E (4.4%), F (1.5%), and Clade I (0.7%), with B2 being related to highly virulent traits. The strains presented elevated resistance to antimicrobials such as ciprofloxacin, streptomycin, cephalexin, florfenicol, and ampicillin. More than 90% of the strains were identified as multidrug-resistant, indicating the selection that is induced by the high use of antimicrobials in swine farming.

Laser therapy for genitourinary syndrome of menopause: systematic review and meta-analysis of randomized controlled trial

Abstract Objective: This meta-analysis of randomized controlled trials (RCTs) aimed to update evidence on the effectiveness and safety of laser therapy for treating genitourinary syndrome of menopause (GSM). Data sources: Manuscripts published until May 2023 were systematically searched in PubMed; Embase; Scopus; Web of Science; CENTRAL; CINAHL; and clinical trial databases (www.trialscentral.org, www.controlled-trials.com, and clinicaltrials.gov), with no language and year of publication restriction. Studies selection: RCTs with women diagnosed with GSM, and the intervention was vaginal laser therapy (CO2-laser or Er: YAG-laser) comparing with placebo (sham therapy), no treatment or vaginal estrogen therapy. Data collection: Two authors evaluated the publications for inclusion based on the title and abstract, followed by reviewing the relevant full-text articles. Disagreements during the review process were addressed by consensus, with the involvement of a third author. Data synthesis: Twelve RCTs, representing a total of 5147 participants, were included in this review. Vaginal health index (VHI) significantly improved in the carbon dioxide laser (CO2-laser) therapy group (MD=2.21; 95% CI=1.25 to 3.16), while dyspareunia (MD=−0.85; 95% CI=−1.59 to −0.10), dryness (MD=−0.62; 95% CI=−1.12 to −0.12) and burning (MD= −0.64; 95% CI=−1.28 to −0.01) decreased. No serious adverse effects were reported. Conclusion: CO2-laser increases VHI score and decreases dyspareunia, dryness and burning, especially when compared to sham-laser. However, the certainty of the evidence is low, thus preventing the recommendation of laser therapy for GSM management.

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.

Ureteral obstruction may activate kidney latent tuberculosis. A qualitative study.

Objectives: To analyze the hypothesis that ureteral obstruction may activate kidney latent tuberculous though qualitative study of Urogenital Tuberculosis patients. Methods: A qualitative study was conducted using semistructured interviews in eight patients with Urogenital Tuberculosis. The progression of the disease from the initial symptoms was characterized through the analysis of the clinical and radiological data. The presence of ureteral obstruction prior to the onset of renal tuberculosis was observed in three patients. Results: Patient 1: A 58-year-old female had five episodes of acute left ureteral lithiasis in two years prior to left kidney tuberculosis. Patient 2: A 55-year-old male patient had a 1.2 cm proximal left ureteral stone and in the following six months, the diagnosis of tuberculosis was made in a nonfunctioning left kidney with ureteral thickening and stenosis. Patient 3: A 47-year-old male patient had a 1.2 cm stone in the proximal right ureter and developed urinary tuberculosis with a nonfunctioning right kidney and a contracted bladder. Conclusion: Kidney tuberculosis may appear in the same kidney that had previously suffered stone ureteral obstruction, which may have created local conditions for the activation of latent foci of renal tuberculosis.

Thoracic kidney and diaphragmatic hernia: prenatal diagnosis and successful management. Case report and review of the literature / Riñón torácico y hernia diafragmática: diagnóstico prenatal y manejo exitoso. Reporte de caso y revisión de la literatura.

Objectives: To report a case of prenatal diagnosis of ectopic intrathoracic kidney with diaphragmatic hernia managed surgically after birth, and to conduct a review of the literature on prenatal diagnosis of ectopic intrathoracic kidney and perinatal prognosis. Material and methods: We report the case of a 28-week fetus in which, on ultrasound imaging, a mass was observed displacing the heart and lung in the right hemithorax, which was was confirmed by magnetic resonance (MR) to be an ectopic intrathoracic kidney (ITEK). After birth, the neonate was approached by laparoscopy to place a mesh in continuity with the diaphragm, leaving the kidney in the abdomen, with good evolution. A search was conducted in the PubMed, Embase and Cochrane databases for cohorts, case reports and case series of prenatal diagnosis of intrathoracic kidney in the fetus. Information was retrieved regarding design, population, imaging diagnosis, treatment and prognosis. Results: The search identified 8 studies that met the inclusion criteria, reporting a total of 8 cases. Ultrasound diagnosis showed ectopic intrathoracic kidney associated with diaphragmatic hernia in all the subjects. Fetal magnetic resonance imaging (MRI) was also used in 5 cases. Conclusions: Ectopic intrathoracic kidney is a congenital abnormality amenable to prenatal diagnosis. Survival after corrective surgery performed in the neonatal period is common. There is a paucity of publications, limited to case reports, regarding the prenatal diagnosis of this condition.

Objetivos: reportar un caso de diagnóstico prenatal de riñón ectópico intratorácico (REI) con hernia diafragmática y manejo quirúrgico neonatal, y hacer una revisión de la literatura sobre diagnóstico prenatal de REI y el pronóstico perinatal. Materiales y métodos: se reporta el caso de un feto de 28 semanas en el que se observó imagen ecográfica sugestiva de masa en hemitórax derecho que desplazaba corazón y pulmón; se confirmó que correspondía a un riñón intratorácico. Por laparoscopia, al recién nacido se le colocó una malla en continuidad con el diafragma dejando el riñón en el abdomen, con buena evolución. Se realizó una búsqueda bibliográfica en PubMed, Embase y Cochrane. Se buscaron cohortes, reportes y series de caso de gestaciones con diagnóstico prenatal de riñón intratorácico fetal. Se extrajo información del diseño, la población, el diagnóstico por imágenes, el tratamiento y el pronóstico. Resultados: en la búsqueda se identificaron 8 estudios que cumplieron con los criterios de inclusión y que informan en total ocho casos. El diagnóstico ecográfico mostró REI asociado a hernia diafragmática en todos los sujetos. Se utilizó también la RM fetal en cinco casos. Seis neonatos sobrevivieron sin complicaciones, en uno hubo interrupción voluntaria del embarazo, y otro presentó sepsis y dificultad respiratoria, finalmente fue dado de alta en buenas condiciones. Conclusiones: el REI es una anomalía congénita susceptible de diagnóstico prenatal. La sobrevida a la cirugía correctora en el periodo neonatal es frecuente. La literatura disponible en torno al diagnóstico prenatal de REI es escasa y se limita a reportes de casos.

Factores de riesgo asociados a anomalías congénitas renales y de vías urinarias / Risk factors associated with congenital renal and urinary tract anomalies

Introducción: Las anomalías congénitas renales y de las vías urinarias constituyen la principal causa de enfermedad renal crónica en la edad pediátrica. Su etiología es multifactorial. Intervienen factores maternos, genéticos y ambientales. En Cuba, las afecciones congénitas del riñón y las vías urinarias constituyen una latente preocupación y aunque se ha incrementado el diagnóstico prenatal de las mismas, el número de pacientes diagnosticados es alto. Objetivo: Contribuir al conocimiento de la comunidad científica en relación con los factores de riesgo asociados a las anomalías del desarrollo renal. Métodos: Se realizó una revisión sistemática de la literatura médica disponible en las bases de datos Ebsco, SciELO, Scopus, Pubmed, revistas de nefrología pediátrica, pediatría, genética y teratología; y en la red social académica: Researchgate. Se accedió, durante los últimos cinco años, a varios artículos publicados en español y en inglés. Se utilizaron los descriptores Congenital anomalies of the kidney and urinary tract, hydronephrosis, risk factors, prenatal diagnosis, congenital abnormalities. Conclusiones: La presencia de la diabetes, desde la etapa preconcepcional y durante las primeras semanas del embarazo, la obesidad, las dietas maternas bajas en proteínas, y las alteraciones de la fertilidad, se asocian a las anomalías del desarrollo renal. Existen factores de riesgo específicos para determinados tipos de defectos congénitos renales y de las vías urinarias. No se considera, que el consumo del ácido fólico tenga un papel protector sobre las alteraciones de la embriogénesis renal, por lo que se recomienda ser cauteloso con la dosis que se administra a las embarazadas.

Introduction: congenital renal and urinary tract anomalies are the main cause of chronic kidney disease in children. Its etiology is multifactorial. Maternal, genetic and environmental factors are involved. In Cuba, congenital renal and urinary tract affections constitute a latent concern, and although their prenatal diagnoses have increased, the number of diagnosed patients is high. Objective: to contribute to the knowledge of the scientific community in relation to the risk factors associated with renal developmental anomalies. Methods: a systematic review of the available medical literature was carried out in Ebsco, SciELO, Scopus and Pubmed databases, in pediatric nephrology, pediatrics, genetics, and teratology journals as well as in the academic social network: Researchgate. Several articles published in Spanish and English languages were accessed during the last five years. The used descriptors were congenital anomalies of the kidney and urinary tract, hydronephrosis, risk factors, prenatal diagnosis and congenital abnormalities. Conclusions: the presence of diabetes, from the preconceptional stage and during the first weeks of pregnancy, obesity, maternal diets low in protein, and fertility disorders, are associated with renal developmental anomalies. There are specific risk factors for certain types of kidney and urinary tract birth defects. It is not considered that the consumption of folic acid has a protective role on the alterations of renal embryogenesis, so it is recommended to be cautious with the dose administered to pregnant women.

Information was retrieved regarding design, population, imaging diagnosis, treatment and prognosis. Results: The search identified 8 studies that met the inclusion criteria, reporting a total of 8 cases. Ultrasound diagnosis showed ectopic intrathoracic kidney associated with diaphragmatic hernia in all the subjects. Fetal magnetic resonance imaging (MRI) was also used in 5 cases. Conclusions: Ectopic intrathoracic kidney is a congenital abnormality amenable to prenatal diagnosis. Survival after corrective surgery performed in the neonatal period is common. There is a paucity of publications, limited to case reports, regarding the prenatal diagnosis of this condition.

Urogenital development and sexual differentiation in males of the species Dasyprocta fuliginosa.

Thirteen black agouti (Dasyprocta fuliginosa) male fetuses, acquired in two areas of the Amazon Forest, were used for the purpose of morphologically describing the fetal male urogenital organs with a focus on addressing histological and macroscopic aspects. The organs of interest were dissected and photographed in situ and ex situ. Fragments were collected and subjected to routine histological processing for inclusion in paraffin, which was cut and stained by haematoxylin and eosin and Gomori's Trichrome methods and subsequently analysed in a light microscope. The results showed that the urinary tract is like that of domestic animals and is composed of smooth unilobed kidneys covered by a dense capsule of connective tissue and divided into two well-defined regions, cortical and medullary. Ureters, urethra and urinary bladder also showed macroscopic and microscopic characteristics similar to those of domestic animals. The penis of these animals has fibroelastic characteristics, with numerous keratinized structures at its apex. In the middle third of the penis, a "U" shaped penile flexure was seen; the glans penis is covered by a keratinized epidermis containing horny spicules. The presence of a penile bone in an endochondral ossification process was observed, being more developed in gestational ages greater than 76 days. The annex glands were not observed, probably because they were fetuses; only the ampulla of the ductus deferens was identified.

Epidemiological Overview of Urogenital Gonorrhea in Mexico (2003-2020).

In Mexico, urogenital gonorrhea (UG) is one of the main sexually transmitted diseases notifiable by health systems around the world. Epidemiological data on sexually transmitted infections (STIs) in Mexico indicated that UG was "under control" until 2017. However, international epidemiological reports indicate the increase in incidence due to several factors, including an increase during the first year of the COVID-19 pandemic. These factors suggest that this phenomenon may occur in developing countries, including Mexico. Therefore, the aim of this study was to analyze national surveillance data on UG from 2003-2019 and the first year of the COVID-19 pandemic. An epidemiological study of cases and incidence of UG (2003-2020) was performed in the annual reports issued by the General Directorate Epidemiology in Mexico. Cases and incidence were classified and analyzed by year, sex, age group, and seasons (by temperature). Distribution of UG was carried out using heat maps for the whole country. Ultimately, a seasonal and correlation analysis was performed for UG cases versus temperature. The results showed that the distribution of cases and incidence by sex showed that there was no variation over 14 years. From 2016 onward, a significant increase in UG was observed before the pandemic. During the first year of the pandemic, a significant increase was observed in females aged 24-44 years. A heterogeneous distribution of UG was identified; however, border states were ranked among the top states with elevated incidences and cases. Lastly, the occurrence of UG was associated with temperature, related to summer. The information presented is intended to be useful to promote prevention and to contribute to visualize the distribution of UG over the last 18 years for decision making, and to show one of the consequences of the collapse of epidemiological surveillance of UG during the first year of the COVID-19 pandemic.

Bacterial dysbiosis and epithelial status of the California sea lion (Zalophus californianus) in the Gulf of California.

Despite the high incidence of urogenital carcinoma (UGC) in California sea lions stranded along California, no UGC has been reported in other areas of their distribution; however, cell morphologies typical of premalignant states have been found. Risk factors for UGC include high of organochlorines and infection with a gammaherpesvirus, OtHV-1, but the importance of the bacteriome for epithelial status remains unknown. We characterized the genital bacteriome of adult female California sea lions along their distribution in the Gulf of California and examined whether the diversity and abundance of the bacteriome varied spatially, whether there were detectable differences in the bacteriome between healthy and altered epithelia, and whether the bacteriome was different in California sea lions infected with OtHV-1 or papillomavirus. We detected 2270 ASVs in the genital samples, of which 35 met the criteria for inclusion in the core bacteriome. Fusobacteriia and Clostridia were present in all samples, at high abundances, and Actinobacteria, Alphaproteobacteria, and Campylobacteria were also well-represented. Alpha diversity and abundance of the California sea lion genital bacteriome varied geographically. The abundance of bacterial ASVs varied depending on the genital epithelial status and inflammation, with differences driven by classes Fusobacteriia, Clostridia, Campylobacteria and Alphaproteobacteria. Alpha diversity and abundance were lowest in samples in which OtHV-1 was detected, and highest those with papillomavirus. Our study is the first investigation of how the bacteriome is related to epithelial status in a wild marine species prone to developing cancer.

First record of a rare case of accidental urinary myiasis by Telmatoscopus albipunctata (Diptera: Psychodidae), with morphological description, in a human in Brazil.

Telmatoscopus albipunctata is an insect of the Psychodidae family, with a worldwide distribution, particularly in tropical and subtropical countries. Although it does not have hematophagous habits, it has veterinary medical importance due to the mechanical transmission of protozoa and bacteria, many of which cause nosocomial infections. This dipteran has been reported as one of the causative agents of accidental myiasis in humans in several countries, and since it has not been registered in South America, the objective of the present report was to describe a rare case of accidental urinary myiasis caused by T. albipunctata (Diptera: Psychodidae) in humans in Brazil. In the present report, a 25-year-old female patient, resident of the central region of the state of Rio Grande do Sul, Brazil, sought medical attention after finding larvae in her urine. She complained of vaginal itching and skin dermatitis. The larvae were sent to the Veterinary Parasitology Laboratory of the Federal University of Santa Maria, where they were mounted on permanent slides for further taxonomic identification. Morphological characteristics allowed the identification of fourth-stage larvae and pupae of T. albipunctata. Therefore, the present work reports the first record of accidental urinary myiasis caused by T. albipunctata infection in Brazil and South America.

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.
