Vulvar tuberculosis-A rare manifestation of the disease / Tuberculose vulvar - Uma manifestação rara da doença

Abstract Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. According to data from the World Health Organization, this disease remains one of the leading causes of death worldwide. Although it most commonly affects the lungs, tuberculosis can compromise any organ. The present study reports a rare case of vulvar tuberculosis in a postmenopausal woman with a history of asymptomatic pulmonary and pleural tuberculosis, with no prior documented contact with the bacillus. Diagnosis was based on vulvar lesion biopsies, with histological findings suggestive of infection and isolation of M. tuberculosis by microbiological culture and polymerase chain reaction (PCR) essays. The lesions reverted to normal after tuberculostatic therapy.

Resumo A tuberculose é uma doença infeciosa causada pelo Mycobacterium tuberculosis. De acordo com dados da Organização Mundial de Saúde, esta doença mantém-se entre as principais causas demorte nomundo. Embora afetemais frequentemente os pulmões, a tuberculose pode comprometer qualquer órgão. O presente artigo relata um caso raro de tuberculose vulvar numa mulher na pós-menopausa, com antecedentes de tuberculose pleural e pulmonar assintomática, sem contato documentado com o bacilo. O diagnóstico foi feito com base na biópsia da lesão vulvar, com achados histológicos sugestivos da infeção e isolamento do M. tuberculosis pormeios de cultura e pela técnica da reação em cadeia da polimerase (PCR). Após terapêutica tuberculostática, as lesões reverteram.

Prevalencia del Streptococcus B en el tracto genital inferior en embarazadas entre 35 y 37 semanas: Hospital de San José / Prevalence of group B Streptococcus infection of the lower genital tract in 35 to 37-week pregnancies

Introducción: la infección es la causa más importante de morbimortalidad en las unidades de cuidado intensivo neonatal a nivel mundial, por lo regular causadas por Streptococcus del grupo B. Objetivos: describir la prevalencia de colonización del germen en el tracto genital inferior de gestantes entre las semanas 35.0 y 37.6 en el Hospital de San José. Materiales y métodos: estudio descriptivo de corte transversal. Se realizaron cultivos vaginal y anorrectal a todas las pacientes, procesados de manera independiente y ante la positividad se administró profilaxis. Resultados: entre marzo 2008 y marzo 2009 se evaluaron 112 gestantes. La prevalencia del microorganismo fue 15,2% (n=17) y la edad promedio fue de 28 años (DE 6.2). La actividad sexual en el tercer trimestre (51,8%), la primiparidad (48,2%) y el antecedente de vaginosis en III trimestre (44,6%) fueron los factores observados con mayor frecuencia, sin encontrar asociación estadística significativa con la presencia del germen. Conclusiones: la prevalencia del Streptococcus B fue similar a la reportada en otras publicaciones de países desarrollados o en vía de desarrollo. Teniendo en cuenta el impacto que tiene esta colonización del tracto genital inferior con desenlaces maternos y neonatales, debería considerarse la realización de esta prueba como tamizaje en pacientes gestantes en el tercer trimestre.

Introduction: worldwide, infection, usually caused by Group B Streptococcus, is the leading cause of morbidity/mortality at the neonatal intensive care units. Objectives: to describe the prevalence of colonization by this microorganism in the lower genital tract of pregnant women between weeks 35.0 and 37.6 at Hospital de San José. Materials and Methods: this is a cross sectional descriptive study. Vagina and rectum specimens were cultured for all patients, independently processed and prophylactic treatment was given when culture positive. Results: 112 pregnant patients were assessed between March 2008 and March 2009. Prevalence of the microorganism was 15.2% (n=17) and mean age was 28 years (SD 6.2). The most frequent factors were: sexual activity in the third trimester (51.8%), primigravity (48.2%) and a history of third-trimester vaginal infection (44.6%), finding no statistically significant association with the presence of the studied germ. Conclusions: the prevalence of Group B Streptococcus infection was similar to that reported in literature of other developed or developing countries. The impact this colonization of the lower genital tract has on maternal and neonatal outcomes is an indication to recommend this test on third-trimester pregnant patients as a screening strategy.

Measuring the quality of performance of a genitourinary medicine primary care team / Medición de la calidad de los resultados de la medicina genitourinaria del equipo de atención primaria

OBJECTIVES: To measure the quality of the clinical Genitourinary (G-U) Medicine and Sexually Transmitted Infection (GUM/STI) management process at a primary care polyclinic and establish a baseline for future monitoring and evaluation. METHODS: This was a prospective cohort study on 220 data abstracted clinical notes randomly selected and stratified by gender, age and first point of contact from 2131 GU/STI patients of the GUM/STI clinic seen from 2003-5. Data were also obtained by tele-interview of a subset of 27 individuals. Measurements were incidence (95% CI) as proportions of successful level of activity and outcome indicators for diagnosis, treatment and prognosis. RESULTS:Among 220 patients, the incidence (95% CI) of accurate clinical diagnosis and treatment was 40.5% (33%, 46%) before laboratory results boosted it to 96% (93%, 99%). Successful prognosis at 1st, 2nd and 3rd follow-up was 23.2%, 56.6% and 86.2%. The risk at follow-up for 1, 2 and >2 GU/STI episodes was 28.9%, 45.8% and 25.3%. Follow-up of partners was low, 4.7%. Adequate health promotion and preventive services were reported in 86.5% (78%, 88%) of 220 patients' records and by 84.5% (71%, 98%) of 26 who were tele-interviewed. In 88.5% (76%, 100%) of those (27) tele-interviewed, there was satisfaction with the service, but 73.8% (56%, 90%) would have preferred appointments and 29.6% (12%, 47%) preferred extended hours. Per capita ideal cost of medication could have been BB$6.30 (± 1.56) instead of actual BB$13.05 (± 1.84); (BB$2 = US$1). CONCLUSION: GU/STI quality performance improvement in Barbados requires rapid laboratory diag-nosis, standardized data formats with prompt expedited partner notification and treatment appointments and use of recommended algorithm that can half the cost of medication. Genitourinary medicine should be strategized instead of STI to better encapsulate the spectrum diversity of presentations and points of service.

OBJETIVO: Medir la calidad de la medicina genitourinaria clínica y el proceso del tratamiento de las infecciones de transmisión sexual (MGU/ITS) en un policlínico de atención primaria, y establecer una línea de base para el monitoreo y la evaluación futuros. MÉTODOS: Se trató de un estudio de cohorte prospectivo realizados sobre 220 notas clínicas extraídas de datos, seleccionadas aleatoriamente y estratificadas por género, edad y primer punto de contacto, de 2131 pacientes MGU/ITS de la clínica MGU/ITS atendidos en 2003-2005, y por tele-entrevista de un subconjunto de 27 individuos. Las mediciones fueron incidencias (95% IC) como proporciones del nivel de éxito de la actividad e indicadores de los resultados para el diagnóstico, el tratamiento y la prognosis. RESULTADOS: Entre 220 pacientes, la incidencia (95% IC) del diagnóstico clínico exacto y el tratamiento fue 40.5% (33%, 46%) antes de que los resultados de laboratorio la elevaran a 96% (93%, 99%). La prognosis exitosa en el primer, segundo y tercer seguimiento fue 23.2%, 56.6% y 86.2%. El riesgo en el seguimiento para los episodios GU/ITS 1, 2, y > 2 fue 28.9%, 45.8% y 25.3%. El seguimiento de parejas fue bajo, 4.7%. La promoción adecuada de la salud y los servicios de prevención fueron reportados en 86.5% (78%, 88%) de las historias de 220 pacientes y por 84.5% (71%, 98%) de 26 que fueron tele-entrevistados. En 88.5% (76%, 100%) de los (27) tele-entrevistados, hubo satisfacción con el servicio, pero 73.8% (56%, 90%) hubiera preferido citas y 29.6% (12%, 47%) extensión del horario. El costo ideal per capita de la medicación podría haber sido 6.30 BBD (± 1.56) en lugar de 13.05 BBD (± 1.84); (2 BBD = 1 USD). CONCLUSIONES: El mejoramiento en cuanto a resultados de calidad en GU/ITS en Barbados, requiere diagnósticos de laboratorio rápidos, formatos estandarizados de datos con pronta notificación a las parejas, citas para el tratamiento, y uso del algoritmo recomendado que puede reducir a la mitad el costo de la medicación. MUG debe ser estrategizada en lugar del TIS, a fin de encapsular mejor el espectro de la diversidad en las presentaciones y puntos de servicio.

Ressonância magnética na endometriose do trato urinário baixo: ensaio iconográfico / Magnetic resonance imaging in lower urinary tract endometriosis: iconographic essay

Endometriose é definida como a presença de tecido endometrial funcionante fora da cavidade endometrial e do miométrio. É uma doença comum, de causas multifatoriais, porém o envolvimento do trato urinário baixo é raro. A ressonância magnética tem elevada sensibilidade, especificidade e acurácia no diagnóstico da endometriose do trato geniturinário baixo, principalmente por permitir a identificação das lesões de permeio a aderências e a avaliação da extensão das lesões subperitoneais. Neste estudo são ilustrados, sob a forma de ensaio iconográfico, os principais achados à ressonância magnética do envolvimento por endometriose do trato urinário baixo.

Endometriosis is defined as the presence of functional endometrial tissue outside the endometrial cavity and myometrium. Although this is a frequent disease with multifactorial causes, involvement of the lower urinary tract is rare. Magnetic resonance imaging is highly sensitive, specific and accurate in the diagnosis of endometriosis in the lower urinary tract, especially for allowing the identification of lesions obscured by adhesions or with subperitoneal extension. The present iconographic essay presents the main magnetic resonance imaging findings of the lower urinary tract involvement by endometriosis.

Detección de Mycoplasma genitalium y correlación con manifestaciones clínicas en una población del estado Zulia, Venezuela / Mycoplasma genitalium detection and correlation with clinical manifestations in population of the Zulia State, Venezuela

Diverse studies demonstrate an association between Mycoplasma genitalium and urogenital pathologies. The aim of this study was to investigate the prevalence of M. genitalium in patients attending gynecological evaluation in private clinics (n = 172). DNA amplification assays of the genes 16S rRNA and MgPa were utilized. The prevalence of M. genitalium in the study population was 7.5 percent. M. genitalium was detected in 12.1 percent and 4.1 percent of the symptomatic and asymptomatic patients, respectively (p = 0.047). The infection was diagnosed in patients with cervicitis (17.2 percent) and mucopurulent secretion (16.6 percent) and the highest prevalence of infections was registered in the 31-40 years age group. No significant association between the presence of M.genitalium and individual clinical manifestations or the patients age was showed (p > 0.05). The high prevalence of M. genitalium infections, mostly in patients with clinical manifestations showed in this study, warrants the application of diagnostic strategies in the population to investigate the clinical meaning of these microorganisms and to reevaluate therapeutic schemes against non-gonococcal and non-chlamydial infections.

Diversos estudios demuestran una asociación entre Mycoplasma genitalium y patologías urogenitales. El objetivo de este trabajo fue investigar la prevalencia de infecciones por M. genitalium en pacientes atendidas en clínicas privadas (n = 172). Se utilizaron ensayos de amplificación de genes 16S rARN y MgPa. La prevalencia de M. genitalium en esta población fue 7,5 por ciento. Mycoplasma genitalium fue detectado en 12,1 y 4,1 por ciento) de las pacientes sintomáticas y asintomáticas, respectivamente (p = 0,047). La infección se diagnosticó en pacientes con cervicitis (17,2 por ciento) y con secreción mucopurulenta (16,6 por ciento) y la mayor prevalencia de infecciones se registró en el grupo etario de 31 a 40 años. No se encontró asociación significativa entre la presencia de M. genitalium y manifestaciones clínicas individuales o edad de las pacientes (p > 0,05). La alta prevalencia de infecciones por M. genitalium, principalmente en pacientes con manifestaciones clínicas demostrada en este estudio, demanda la aplicación de estrategias diagnósticas en la población para investigar el significado clínico de estos microorganismos y reevaluar esquemas terapéuticos contra infecciones no gonocóccicas y no clamidiales.

Pudendal somatosensory evoked potentials in normal women

OBJECTIVE: Somatosensory evoked potential (SSEP) is an electrophysiological test used to evaluate sensory innervations in peripheral and central neuropathies. Pudendal SSEP has been studied in dysfunctions related to the lower urinary tract and pelvic floor. Although some authors have already described technical details pertaining to the method, the standardization and the influence of physiological variables in normative values have not yet been established, especially for women. The aim of the study was to describe normal values of the pudendal SSEP and to compare technical details with those described by other authors. MATERIALS AND METHODS: The clitoral sensory threshold and pudendal SSEP latency was accomplished in 38 normal volunteers. The results obtained from stimulation performed on each side of the clitoris were compared to ages, body mass index (BMI) and number of pregnancies. RESULTS: The values of clitoral sensory threshold and P1 latency with clitoral left stimulation were respectively, 3.64 ± 1.01 mA and 37.68 ± 2.60 ms. Results obtained with clitoral right stimulation were 3.84 ± 1.53 mA and 37.42 ± 3.12 ms, respectively. There were no correlations between clitoral sensory threshold and P1 latency with age, BMI or height of the volunteers. A significant difference was found in P1 latency between nulliparous women and volunteers who had been previously submitted to cesarean section. CONCLUSIONS: The SSEP latency represents an accessible and reproducible method to investigate the afferent pathways from the genitourinary tract. These results could be used as normative values in studies involving genitourinary neuropathies in order to better clarify voiding and sexual dysfunctions in females.
