Síndrome de pseudotumor cerebri en la población pediátrica: características clínicas, tratamiento y pronóstico / Pseudotumor cerebri in the paediatric population: clinical features, treatment and prognosis

Introducción El síndrome de pseudotumor cerebri (SPTC) en pacientes prepuberales presenta características que lo diferencian respecto a su presentación en la etapa pospuberal. Nuestro objetivo es describir las características de los pacientes diagnosticados de SPTC pediátrico en nuestro centro y compararlas en función de su estado puberal. Pacientes y métodos Se incluyeron a los pacientes diagnosticados de SPTC en un hospital de tercer nivel entre los años 2006 y 2019 con edades comprendidas entre uno y 18 años que cumplieran los criterios diagnósticos actualizados del SPTC. Se clasificaron en función de su estado puberal y peso corporal. Posteriormente, se analizaron los datos de las punciones lumbares, estudios de neuroimagen, valoraciones oftalmológicas, así como el régimen terapéutico recibido a lo largo de su seguimiento. Resultados Se recogieron 28 pacientes, 22 prepuberales y seis pospuberales, con edad media de 9,04 ± 2,86 años. El 83,3% de los pacientes pospuberales eran varones presentando sobrepeso/obesidad en el 66,7%. Eran varones el 27% de los pacientes prepuberales, de ellos asociaban sobrepeso el 31,8%. La sintomatología más frecuente fue cefalea (89,9%) y visión borrosa (42,9%). Todos los pacientes presentaron papiledema; un 21,4% de los casos presentaron parálisis del VI par. Se identificó un posible desencadenante en un 28,6%. El 19% presentaron recurrencia clínica, siendo todos ellos prepuberales. La resolución clínica completa se produjo en el 55,6% de los pacientes. Conclusión Pacientes con SPTC presentan menor prevalencia de obesidad en la etapa prepuberal, junto con un mayor porcentaje de etiologías secundarias y tasa de recurrencia que los pacientes pospuberales.

Introduction Pseudotumor cerebri (PC) in prepubertal patients displays certain characteristics that differentiate it from its presentation at the postpubertal stage. The aim of this study is to describe the characteristics of paediatric patients diagnosed with PC at our centre and to compare them according to their pubertal status. Patients and methods We included patients aged between 1 and 18 years who were diagnosed with PC in a tertiary-level hospital between 2006 and 2019 and who met the updated diagnostic criteria for PC. They were classified according to body weight and pubertal status. Subsequently, we analysed results from lumbar punctures, neuroimaging studies, ophthalmological assessments, and treatments received during follow-up. Results We included 28 patients, of whom 22 were of prepubertal age and 6 were of postpubertal age. The mean age (standard deviation) was 9.04 (2.86) years. Among the postpubertal patients, 83.3% were boys, 66.7% of whom presented overweight/obesity. In the group of prepubertal patients, 27% were boys, 31.8% of whom were overweight. The most frequent symptoms were headache (89.9%) and blurred vision (42.9%). All patients presented papilloedema, and 21.4% manifested sixth nerve palsy. Possible triggers were identified in 28.6% of cases. Nineteen percent of patients presented clinical recurrence, all of whom were prepubertal patients. Complete clinical resolution was achieved in 55.6% of patients. Conclusion Prepubertal patients with PC show lower prevalence of obesity, higher prevalence of secondary aetiologies, and higher recurrence rates than postpubertal patients. (AU)

Hiperplasia prostática benigna (HPB), sintomas do trato urinário inferior (LUTS) e função sexual / Benign Prostatic Hyperplasia (BPH), Lower Urinary Tract Symptoms (LUTS), and Sexual Function

A hiperplasia prostática benigna (HPB) representa o crescimento não maligno do tecido da próstata. Proliferação de células estromais e epiteliais na zona de transição da próstata causa compressão uretral e obstrução do fluxo vesical. Isso pode levar a manifestações de LUTS (lower urinary tract symptoms): urgência urinária, noctúria, dificuldades de micção, esvaziamento incompleto da bexiga, menor força e/ ou interrupção do jato e inflamações. Mecanismos do LUTS/HPB compartilhados afetam a função sexual masculina. Atividade aumentada de subtipos de receptores α1-adrenérgicos na próstata está associada à HPB. Tais receptores, também presentes no pênis, podem inibir a ereção, devido à HPB. Quanto à correlação entre LUTS e disfunção sexual, aventa-se que ambas resultem da contração anômala da musculatura lisa, por ativação dos receptores α1-adrenérgicos. LUTS/HPB causam desconforto nos homens, devido à obstrução urinária, ejaculação dolorosa, disfunção erétil (DE), distúrbios ejaculatórios e baixa libido, que prejudicam a qualidade de vida, deles e de suas parcerias. A noctúria interfere negativamente na qualidade do sono e na disposição para a atividade sexual. Tratamentos para LUTS/HPB podem induzir disfunções sexuais. Entre eles, ressecção transuretral (RTU), α1-bloqueadores, inibidores da 5α-redutase e terapia combinada (α1-bloqueador e 5α-redutase). Os efeitos prejudiciais do LUTS/HPB e de seu tratamento sobre a função sexual ainda são subdiagnosticados e insuficientemente tratados. A atividade sexual deve ser investigada antes e durante o tratamento, também orientando o paciente sobre os possíveis efeitos de cada opção terapêutica sobre a função sexual, evitando-se assim o abandono do tratamento.

Changes in benign prostatic hyperplasia management in Valencia: a real-world evidence analysis.

INTRODUCTION AND OBJECTIVES: A training program was developed to increase general practitioners' engagement in the optimal management of Benign Prostatic Hyperplasia (BPH). The goal of this study was to evaluate changes in BPH management after the implementation of a training program. MATERIAL AND METHODS: This observational retrospective cohort study was conducted between 2019 and 2020. Aggregated data were analyzed in three evaluation periods (2010, 2012 and 2015), addressing quality indicators for diagnosis, treatment, and treatment outcomes. RESULTS: Overall, 118 795 patients who presented any data points were included. All quality indicators (number of IPSS and PSA determinations) increased between the first period and the last. Combination (α-blocker + 5-ARI) therapy was increasingly prescribed during the study periods whereas the proportion of prescriptions for single-agent α-blocker showed no significant differences among the periods analyzed. However, the total number of patients eligible for combination therapy who actually received this treatment was low in all periods (7.5%, 17.9%, and 20.1%, in 2010, 2012, and 2015, respectively). The outcome indicators revealed a decrease in referrals to the urology unit mostly among newly diagnosed patients. Even though the proportion of patients who underwent BPH-related surgeries increased significantly from the first to the second period, the number of surgeries remained stable between the second and third periods. CONCLUSIONS: The training program had a generally positive impact on the management of BPH patients in PC, but the overall study period may be insufficient to show an effect on some outcome indicators such as the number of surgeries.

Initial experience with thulium fiber laser for prostate enucleation: Analysis of the intraoperative and short-term outcomes in a prospective, multicenter cohort.

INTRODUCTION: Holmium laser enucleation of the prostate has rapidly become the gold standard for the surgical treatment of benign prostate hyperplasia, although thulium fiber laser (TFL) has also been postulated as an effective and safe alternative for prostate enucleation. The aim of this study is to describe our initial experience with the TFL for endoscopic enucleation of the prostate. MATERIAL AND METHODS: All patients proposed to TFL prostate enucleation were included in the analysis, regardless their prostate volume, catheter status and severity of symptoms, in 3 centers. Preoperative characteristics, intraoperative times and functional 3-months follow-up variables were collected, along with complications. RESULTS: Fifty-six patients were available, with a mean age of 68.7 years. Enucleation and morcellation efficiencies were 2.04 and 7.47 g/min, respectively. Median hospital stay was one day. Comparable functional data, pre and 3-month post-surgery was: mean prostate volume 88.9 vs 21.3 g, maximum urinary flow 13.2 vs 27.3 ml/s, post-void residual volume 149 vs 7.8 ml, prostatic specific antigen level 11.2 vs 1 ng/ml, and International Prostate Symptom Score 20.75 vs 3.96. Fourteen out of 56 (25%) patients presented with complications grade ≤2, according to the Clavien-Dindo classification. DISCUSSION: With wider evidence for other urological indications, very recent evidence about the suitability of TFL for prostate enucleation has arisen, since the first case described in 2021. Our results seem to back up these previous successful experiences as long as we obtained good intraoperative and short term follow-up functional results. However, there is still a need of longer follow-up data. CONCLUSIONS: TFL represents a novel technology for prostate enucleation, with a good intraoperative and short follow-up functional results, and a safety profile similar to the observed for those techniques that have been wider used for this indication. Further studies with longer follow-up periods and comparative with these other techniques are necessary.

Tricoblastoma con estudio inmunohistoquímico: reporte de caso / Trichoblastoma with immunohistochemical study: case report

Resumen Introducción: El tricoblastoma es una neoplasia que por su baja frecuencia no se sospecha clínicamente, pero que debe ser diferenciada de un carcinoma de células basales a través del estudio histopatológico. Objetivo: Reportar un tumor sumamente raro que se presenta en sitios donde es frecuente observar carcinomas basocelulares. Caso clínico: Se presenta el caso de una paciente de 34 años, quien mostraba un nódulo deconsistencia firme y bordes definidos en la región frontal derecha. En laevaluación histológica, se encontró un nódulo hipodérmico bien circunscrito,constituidopormasasynidosdecélulasbasaloidesgrandesconnúcleoovoideo y nucléolo visible con empalizada periférica y algunos folículos rudimentarios. Ante estos signos histopatológicos, se planteó el diagnóstico diferencial con carcinoma de células basales y tricogerminoma,yaqueestasneoplasiaspresentanelementos comunes. La inmunohistoquímica mostró que las células tumorales eran positivas en mayor o menor porcentaje parap63,p53,CK20,Bcl2yCD10. Conclusiones: Pensar en el diagnóstico de un tricoblastoma es un reto, ya que tiene características similares al carcinoma de células basales y a otros tumores benignos foliculares como el tricogerminoma. Por ello, es necesario interrelacionar los hallazgos histomorfológicos con los resultados inmunohistoquímicos.

Abstract Introduction : Trichoblastoma is a neoplasm that is not clinically suspected due to its low frequency but must be differentiated from basal cell carcinoma through histopathological study. Aim : To report an extremely rare tumor that occurs in places where it is common to see basal cell carcinomas. Clinical case : The case of a 34-year-old patient is presented, who showed a nodule of firm consistency and defined edges on the right side of the forehead. In the histological evaluation a well-circumscribed hypodermal nodule was found consisting of masses and nests of large basaloid cells with an ovoid nucleus and visible nucleolus with peripheral palisade and some rudimentary follicles. Given these findings, the differential diagnosis with basal cell carcinoma and trichogerminoma was raised, since these neoplasms have common elements. Immunohistochemistry showed that tumor cells were positive in a higher or lesser percentage for: p63, p53, CK20, Bcl2 and CD10. Conclusions : Diagnosingatrichoblastoma is a challenge since it has characteristics similar to basal cell carcinoma and other benign follicular tumors such as trichogerminoma, so it is necessary to interrelate the histomorphological findings with the immunohistochemical results.

Evaluating the effects of preoperative treatment with 5-alpha reductase inhibitors in holmium laser enucleation of the prostate.

INTRODUCTION AND AIM: Patients treated with HoLEP are frequently treated with previous treatments, including 5-alpha-reductase inhibitors (5-ARIs). We investigated the impact of pretreatment with 5-ARIs on perioperative and immediate postoperative parameters in patients treated with HoLEP. MATERIAL AND METHODS: A retrospective study was performed using a prospectively collected database including all patients treated with HoLEP at our center between January 2017 and January 2023. The resected tissue weight, enucleation and morcellation efficiency (enucleation weight/time and morcellation weight/ time), postoperative complications, hospital stay and hemoglobin drop have been analyzed. RESULTS: A total of 327 patients were included. Of these, 173 (52.9%) were treated with 5-ARIs. No differences were found among the perioperative parameters investigated to determine efficiency. No differences were observed in peri- or postoperative complications, hospital stay or hemoglobin drop. CONCLUSIONS: Therapy with 5-ARIs had no impact on the immediate postoperative outcomes of patients treated with HoLEP. In our cohort, we observed that the use of 5-ARIs did not affect surgical efficiency, enucleation or morcellation. Further multicenter studies will be necessary to validate these findings.

Hallazgos mastográficos benignos que simulan malignidad: un dilema diagnóstico / Benign mammographic findings that simulate malignancy: a diagnostic dilemma

Resumen OBJETIVO: Identificar los principales hallazgos histopatológicos benignos y determinar la tasa de falsos positivos que suelen causar conflicto al categorizar las mastografías en el sistema BI-RADS por su aspecto, que puede simular un proceso maligno. MATERIALES Y MÉTODOS: Estudio de cohorte, retrospectivo, efectuado en pacientes atendidas en la Unidad Médica de Alta Especialidad 4 Luis Castelazo Ayala (2019-2023) con reporte mastográfico alterado o sospecha clínica de malignidad. Para el análisis estadístico se utilizó el programa JASP 2.0 y χ2 para la diferencia de proporciones entre grupos. RESULTADOS: De un grupo de 11,481 pacientes, se reportaron 1643 mastografías alteradas: 444 con reportes falsos positivos, 23 pacientes con sospecha clínica y exclusión de 16 que no cumplieron con los criterios de inclusión establecidos. La muestra poblacional estudiada fue de 451 pacientes. La mayoría permaneció asintomática al momento del estudio (42.1%). El hallazgo histopatológico benigno con mayor prevalencia fue el fibroadenoma y su síntoma más relevante el nódulo palpable. La tasa de falsos positivos fue de 4.3%. CONCLUSIONES: En la actualidad, gracias a la implementación de programas de tamizaje es posible establecer diagnósticos de cáncer de mama en etapas tempranas, aunque con la desventaja que el reporte puede resultar falso positivo y ello dar lugar a incremento de la morbilidad y sobretratamiento. Los estándares internacionales indican que estos no deben sobrepasar el 10%.

Abstract OBJECTIVE: To identify the main benign histopathological findings that often cause conflict when categorizing mastographies in the BI-RADS system due to their appearance, which may simulate a malignant process and false positive rate. MATERIALS AND METHODS: Retrospective cohort study carried out in patients attended at the Unidad Médica de Alta Especialidad 4 Luis Castelazo Ayala (2019-2023) with an altered mastographic report or clinical suspicion of malignancy. For statistical analysis we used the JASP 2.0 programme and χ2 for the difference in proportions between groups. RESULTS: From a group of 11,481 patients, 1,643 altered mastograms were reported: 444 with false positive reports, 23 patients with clinical suspicion and exclusion of 16 who did not meet the established inclusion criteria. The population sample studied was 451 patients. The majority remained asymptomatic at the time of the study (42.1%). The most prevalent benign histopathological finding was fibroadenoma and the most relevant symptom was a palpable nodule. The false positive rate was 4.3%. CONCLUSIONS: Currently, thanks to the implementation of screening programmes it is possible to establish breast cancer diagnoses in early stages, although with the disadvantage that the report may be false positive and this may lead to increased morbidity and overtreatment. International standards indicate that these should not exceed 10%.

Miositis aguda asociada a infección por virus influenza. Serie de casos en un hospital pediátrico / Acute myositis associated with influenza infection. Case series in a pediatric hospital

La miositis aguda benigna asociada a influenza es una complicación esporádica. En Argentina, en el año 2022, hubo un aumento temprano de la circulación de influenza y del número total de las notificaciones, con la aparición de miositis secundarias. Serie clínica retrospectiva de nueve pacientes pediátricos que consultaron por dolor e impotencia funcional de extremidades inferiores, y enzimas musculares elevadas, en el hospital Pedro de Elizalde de la Ciudad Autónoma de Buenos Aires, entre agosto y octubre del 2022. En todos se detectó infección por virus influenza y se recuperaron sin secuelas. La miositis aguda benigna es una entidad infrecuente en la infancia, cuyo diagnóstico es predominantemente clínico y de recuperación ad integrum. Debe ser sospechada en pacientes con clínica compatible en contexto de alta circulación viral. La vigilancia epidemiológica aporta herramientas para identificar los virus circulantes y sus posibles complicaciones.

Benign acute myositis associated with influenza is a sporadic complication. In Argentina, in 2022, there was an early increase in influenza circulation and the total number of notifications, with the appearance of secondary myositis. Retrospective clinical series of nine pediatric patients who consulted for pain and functional impotence of the lower extremities, and elevated muscle enzymes, at the Pedro de Elizalde hospital in the Autonomous City of Buenos Aires, between August and October 2022. In all of them, infection by influenza virus and recovered without sequelae. Benign acute myositis is a rare entity in childhood, whose diagnosis is predominantly clinical and recovery ad integrum. It should be suspected in patients with compatible symptoms in a context of high viral circulation. Epidemiological surveillance provides tools to identify circulating viruses and their possible complications.

¿Cuánto tiempo debe permanecer un stent traqueal implantado? Curación de la estenosis luego de 10,16 y 22 años de implante / How Long Should a Tracheal Stent Remain Implanted? Healing of Stenosis 10, 16, and 22 Years After Implantation

RESUMEN Tres stents traqueales fueron removidos luego de 10, 16 y 22 años, a lo que le siguió la correspondiente curación de la estenosis traqueal. Se reportan dos nuevos casos de estenosis traqueal benigna, tratados con prótesis de silicona, que se presentaron a control luego de muy largas ausencias: 16 años en uno y 22 en otro. Se suman a un caso anteriormente publicado y curado luego de 10 años de permanencia del stent, que también presentó una amplia y estable luz traqueal luego la remoción. Se describen los hallazgos endoscópicos, y se incluyen reflexiones sobre la curación de la estenosis observada en todos ellos y su probable relación con el largo tiempo de permanencia de las prótesis. Se investigan las propiedades físicas de los stents, luego de tan prolongado lapso de implante y se las compara con un dispositivo nuevo. Se emite una propuesta que podría conducir a la curación de las estenosis traqueales con tratamiento endoscópico y stent por tiempo prolongado.

ABSTRACT Three tracheal stents were removed after 10, 16, and 22 years, followed by healing of tracheal stenosis. Two new cases of benign tracheal stenosis are reported, treated with silicone pros theses, which presented for follow-up after very long absences: 16 years in one case and 22 years in the other. They add to a previously published case that was healed 10 years after the stent was implanted, which also had a wide and stable tracheal lumen after removal. The endoscopic findings are described, and reflections are included on the healing of the observed stenosis in all cases and its probable relationship with the prolonged indwelling of the prostheses. The physical properties of the stents are inves tigated after such a long period since implantation, and they are compared with a new device. A proposal is put forward that could lead to the healing of tracheal stenosis with endoscopic treatment and prolonged indwelling of the stent.

Terapia termal con vapor de agua: variaciones técnicas entre hospitales universitarios españoles y eficacia a 2 años de seguimiento / Water vapor thermal therapy: technical variations among spanish hospitals and efficacy at 2-year follow-up

Objetivo El objetivo de este trabajo es conocer experiencia inicial con la terapia térmica con vapor de agua (TTVA) para hiperplasia benigna de próstata (HBP) en los hospitales universitarios españoles, así como describir las diferencias en cuanto a técnica y seguimiento observadas entre los centros. Materiales y métodos Este estudio multicéntrico observacional retrospectivo recogió características basales, datos quirúrgicos, posoperatorios y seguimiento a los uno, tres, seis, 12 y 24 meses, incluyendo cuestionarios validados, variaciones flujométricas, complicaciones y la necesidad de tratamiento farmacológico y quirúrgico tras el procedimiento. También se analizaron los posibles desencadenantes de retención aguda de orina (RAO) en el posoperatorio. Resultados Se incluyeron un total de 105 pacientes. No se observaron diferencias entre los grupos con y sin RAO con respecto a tiempo de sondaje (cinco y 4,3 días respectivamente, p = 0,178), ni volumen prostático (47,9 y 41,4 g, respectivamente, p = 0,147). La mejoría media a los tres, seis, 12 y 24 meses en cuanto de flujo máximo fue de 5,3, 5,2, 4,2 y 3,8 mL/s, respectivamente. En cuanto a la eyaculación, se observa una mejoría en la misma a partir de los tres meses de seguimiento que se mantiene en el tiempo. Conclusiones El tratamiento mínimamente invasivo de HBP con TTVA presenta buenos resultados funcionales a 24 meses de seguimiento, sin afectación significativa de la función sexual y con una baja incidencia de complicaciones. Existen pequeñas variaciones principalmente en cuanto al posoperatorio inmediato entre los hospitales participantes en el estudio. (AU)

Aim The aim of this work is to evaluate the initial experience with water vapor thermal therapy (WVTT) for benign prostatic hyperplasia (BPH) in Spanish university hospitals, as well as to describe the differences in technique and follow-up between centers. Materials and Methods This retrospective observational multicenter study collected baseline characteristics, surgical, postoperative and follow-up data at 1, 3, 6, 12 and 24 months, including validated questionnaires, flowmetric variations, complications, and the need for pharmacological or surgical treatment following the procedure. Possible triggers for postoperative acute urinary retention (AUR) were also analyzed. Results A total of 105 patients were included. No differences were observed between the groups with and without AUR with respect to catheterization time (5 and 4.3 days respectively, p = 0.178), or prostate volume (47.9 gr and 41.4 gr respectively, p = 0.147). The mean improvement at 3, 6, 12 and 24 months in terms of peak flow was 5.3, 5.2, 4.2 and 3.8 ml/s, respectively. As for ejaculation, an improvement was observed after 3 months of follow-up and was maintained over time. Conclusions Minimally invasive treatment for BPH with WVTT shows good functional outcomes at 24 months follow-up, without significant impairment of sexual function and a low incidence of complications. There are minor inter-hospital variations, mainly in the immediate postoperative period. (AU)

Calcinosis escrotal: ¿una entidad idiopática? / Scrotal Calcinosis: an Idiopathic Entity?

La calcinosis escrotal es una enfermedad benigna e infrecuente que se presenta en adultos de mediana edad, con múltiples nódulos asintomáticos a nivel de la piel del escroto. Algunos autores vinculan la aparición de estas lesiones a la calcificación secundaria de quistes epidérmicos o ecrinos. Cuando no se encuentra relacionada con dichas entidades ni con alteraciones del metabolismo fosfocálcico, el cuadro se considera idiopático. El tratamiento de elección es quirúrgico, en caso de impacto en la calidad de vida o relevancia estética para el paciente. (AU)

Scrotal calcinosis is a rare, benign disease that presents in middle-aged adults with multiple asymptomatic nodules on the skin of the scrotum. Some authors link the appearance of these lesions to the secondary calcification of epidermal or eccrine cysts. When it is not related to these entities or to alterations in phosphocalcic metabolism, the condition is considered idiopathic. The treatment of choice is surgical, in case of impact on the quality of life or aesthetic relevance for the patient. (AU)

Angina bolhosa hemorrágica: características clínicas, histopatológicas, diagnóstico e estratégias terapêuticas

Introdução: A angina bolhosa hemorrágica (ABH) é uma condição rara, benigna e geralmente assintomática, caracterizada pelo surgimento súbito de bolhas preenchidas com sangue nas superfícies mucosas da cavidade oral e orofaringe. Objetivo: Este trabalho tem como propósito fornecer uma análise abrangente das características clínicas, etiológicas e histopatológicas da angina bolhosa hemorrágica, além de abordar métodos de diagnóstico e opções de tratamento. Materiais e métodos: Foi realizada uma busca por artigos científicos publicados de 2010 a 2023, nas bases de dados Scientific Electronic Library Online (SciELO), US National Library of Medicine (PubMed) e ScienceDirect. Foram coletados artigos em inglês e português utilizando as palavras-chave "angina bolhosa hemorrágica", "estomatite bolhosa hemorrágica benigna", "hemorrhagic bullous angina" e "benign hemorrhagic bullous stomatitis". Conclusão: A ABH é escassamente documentada na literatura, com muitos dados ausentes ou subnotificados. Embora seja uma condição benigna com rápida evolução espontânea, o procedimento diagnóstico deve ser rigoroso para descartar outras possíveis lesões.

Introduction: Hemorrhagic bullous angina (ABH) is a rare, benign and generally asymptomatic condition, characterized by the sudden appearance of blisters filled with blood on the mucous surfaces of the oral cavity and oropharynx. Objective: This work aims to provide a comprehensive analysis of the clinical, etiological and histopathological characteristics of hemorrhagic bullous angina, in addition to addressing diagnostic methods and treatment options. Materials and methods: A search was carried out for scientific articles published from 2010 to 2023, in the Scientific Electronic Library Online (SciELO), US National Library of Medicine (PubMed) and ScienceDirect databases. Articles were collected in English and Portuguese using the keywords "hemorrhagic bullous angina", "benign hemorrhagic bullous stomatitis", "hemorrhagic bullous angina" and "benign hemorrhagic bullous stomatitis". Conclusion: ABH is scarcely documented in the literature, with many data missing or underreported. Although it is a benign condition with rapid spontaneous evolution, the diagnostic procedure must be rigorous to rule out other possible lesions.

Water vapor thermal therapy: Technical variations among spanish hospitals and efficacy at 2-year follow-up.

AIM: The aim of this work is to evaluate the initial experience with water vapor thermal therapy (WVTT) for benign prostatic hyperplasia (BPH) in Spanish university hospitals, as well as to describe the differences in technique and follow-up between centers. MATERIALS AND METHODS: This retrospective observational multicenter study collected baseline characteristics, surgical, postoperative and follow-up data at 1, 3, 6, 12 and 24 months, including validated questionnaires, flowmetric variations, complications, and the need for pharmacological or surgical treatment following the procedure. Possible triggers for postoperative acute urinary retention (AUR) were also analyzed. RESULTS: A total of 105 patients were included. No differences were observed between the groups with and without AUR with respect to catheterization time (5 and 4.3 days respectively, P=.178), or prostate volume (47.9g and 41.4g respectively, P=.147). The mean improvement at 3, 6, 12 and 24 months in terms of peak flow was 5.3, 5.2, 4.2 and 3.8ml/s, respectively. As for ejaculation, an improvement was observed after 3 months of follow-up and was maintained over time. CONCLUSIONS: Minimally invasive treatment for BPH with WVTT shows good functional outcomes at 24 months follow-up, without significant impairment of sexual function and a low incidence of complications. There are minor inter-hospital variations, mainly in the immediate postoperative period.

Hepatotoxicidad por tamsulosina / dutasterida: reporte de un caso probable

La tamsulosina y dutasterida son medicamentos ampliamente usados como tratamiento de la hipertrofia benigna de próstata. teniendo un buen perfil de seguridad. Existen escasos reportes de injuria hepática asociado al uso de tamsulosina; sin embargo, no hay reportes de toxicidad hepática por el uso de dutasterida y del uso combinado de tamsulosina/dutasterida. Se presenta el caso de un varón de 64 años quien desarrolla injuria hepática tras el uso combinado de tamsulosina/dutasterida, desarrollando un patrón de daño hepatocelular y clínica de hepatitis aguda. Se realizo descarte de patología hepática viral, autoinmune y enfermedades metabólicas de depósito, así como de patología biliar mediante ecografía abdominal y colangioresonancia. En la evaluación de causalidad, presentó CIOMS-RUCAM: 6 puntos (probable) y Naranjo: 4 puntos (posible). El paciente presentó respuesta clínica y laboratorial luego de suspender el medicamento.

Tamsulosin and dutasteride are drugs widely used to treat benign prostatic hypertrophy. having a good safety profile. There are few reports of liver injury associated with the use of tamsulosin; however, there are no reports of hepatic toxicity from the use of dutasteride and the combined use of tamsulosin/dutasteride. We present the case of a 64-year-old man who developed liver injury after the combined use of tamsulosin/dutasteride, developing a pattern of hepatocellular damage and acute hepatitis symptoms. Viral, autoimmune, and metabolic storage diseases of the liver were ruled out, as well as biliary pathology by means of abdominal ultrasound and resonance cholangiography. In the causality evaluation, CIOMS-RUCAM presented: 6 points (probable) and Naranjo: 4 points (possible). The patient presented a clinical and laboratory response after discontinuing the drug.

Pólipo fibroepitelial vulvar: una serie de casos

Los pólipos fibroepiteliales son tumores cutáneos benignos frecuentes en la población general. Sin embargo, la afectación del tracto genital es inhabitual. Su etiología no es clara, pero se han descrito asociaciones con trastornos metabólicos y fluctuaciones hormonales, lo cual explica su mayor prevalencia en mujeres. Debido a la variedad de diagnósticos diferenciales, es necesaria la evaluación histopatológica. Su manejo es habitualmente conservador; sin embargo, pueden requerir intervención quirúrgica en algunos casos. Exponemos cuatro casos de tumores fibroepiteliales vulvares de diferentes tamaños, uno de ellos clasificado como gigante, así como la aproximación de manejo. Con esta presentación, esperamos mejorar el conocimiento, la precisión del diagnóstico y contribuir al tratamiento eficaz de las pacientes con esta patología vulvar tan poco frecuente.

Fibroepithelial polyps are common benign skin tumors in the general population. However, genital tract involvement is unusual. Their etiology is unclear, but associations with metabolic disorders and hormonal fluctuations have been described, which explains their higher prevalence in women. Due to the variety of differential diagnoses, histopathological evaluation is necessary. Their management is usually conservative. However, they may require surgical intervention in some cases. We present four cases of vulvar fibroepithelial tumors of different sizes, one of them classified as giant, as well as the management approach. With this presentation, we hope to improve knowledge, diagnostic accuracy and contribute to the effective treatment of patients with this rare vulvar pathology.

Association between interleukin-6 and lower urinary tract symptoms of benign prostatic hyperplasia / Relación entre la interleucina-6 y los síntomas urinarios de la hiperplasia prostática benigna

Objective: To evaluate the association between IL-6 in prostatic tissue/blood sample and BPH-LUTS, so as to preliminarily discover an indicator of inflammation that could show the severity of LUTS. Patients and methods: The prostatic tissues and blood samples were collected from 56 patients who underwent transurethral plasmakinetic resection of the prostate (TUPKRP). The association between IL-6 detected on prostatic tissues/blood sample and LUTS parameters, including international prostate symptom score (IPSS), peak flow rate (Qmax) and urodynamic parameters were analyzed with SPSS version 18.0, and p-value <0.05 was chosen as the criterion for statistical significance. Results: The TPSA and prostate volume (PV) were found to be higher in the inflammation group (p=0.021, 0.036). There was a positive association between prostate tissue inflammation and LUTS ([IPSS, storage symptoms score (SSS), voiding symptoms score (VSS), p<0.05], [Qmax, p=0.025], [obstruction, p=0.027] and [AUR, p=0.018]). The level of serum IL-6 was significantly higher in inflammatory group (p=0.008). However, no differences were observed in different degrees of inflammation (p=0.393). The level of IL-6 in prostatic tissue significantly increased with the degree of inflammation (p<0.001), and the intensity of IL-6 expression was statistically correlative with the degree of inflammation (p<0.001). The IL-6 expression in prostatic tissue was statistically relevant with IPSS (p=0.018) and SSS (p=0.012). Conclusion: IL-6 expression in prostatic tissue is associated with storage IPSS, suggesting chronic inflammation might contribute to storage LUTS. (AU)

Objetivo: Evaluar la relación entre il-6 y bph-lut en muestras de tejido prostático/sangre, con el fin de identificar indicadores de inflamación que reflejen la gravedad de los lut. Pacientes y métodos: Se recolectaron muestras de tejido prostático y sangre de 56 pacientes sometidos a una plasmatectomía transuretral prostática. Se aplicó la versión 18.0 de SPSS para analizar la correlación entre el il-6 de tejido prostático/muestra de sangre y los parámetros relacionados con los LUTS (puntuación internacional de síntomas prostáticos (IPSS), flujo máximo (Qmax), parámetros urodinámicos), con UN valor p<0,05 como criterio para una diferencia estadísticamente significativa. Resultados: Hubo diferencias estadísticamente significativas (p=0,021, 0,036) entre el grupo con inflamación y el grupo sin inflamación en TPSA y PV. La inflamación del tejido prostático se relacionó positivamente con LUTS ([IPSS, puntuación de síntomas de almacenamiento (SSS), puntuación de síntomas de micción (VSS), p<0,001), y la intensidad de la expresión de il-6 se correlacionó estadísticamente con el grado de inflamación (p<0,001). La expresión de il-6 en el tejido prostático fue estadísticamente significativa con IPSS (p=0,018) y SSS (p=0,012). Conclusiones: La expresión de il-6 en el tejido prostático está relacionada con el almacenamiento de IPSS, lo que sugiere que la inflamación crónica puede estar involucrada en el almacenamiento de LUTS.

Safety and efficacy of Rezum™ in erectile dysfunction patients with and without an inflatable penile prosthesis[[es]]Seguridad y eficacia del sistema Rezum® en pacientes con disfunción eréctil con y sin prótesis de pene inflable.

PURPOSE: This study evaluates the safety and efficacy of Rezum™ in erectile dysfunction (ED) patients with and without an inflatable penile prosthesis (IPP). MATERIALS AND METHODS: This was a retrospective review of ED patients who underwent Rezum™ by a single surgeon over 12 months. Patient age, presence of IPP, number of benign prostatic hyperplasia medications, International Prostate Symptom Score (IPSS), IPSS Quality of Life Index (QOL), uroflowmetry maximum flow rate (Qmax), and uroflowmetry average flow rate (Qavg) before and after Rezum™ were obtained. Independent two-sample T-tests were used to compare preoperative and postoperative characteristics between patients with and without an IPP. Linear regression was performed to identify factors associated with postoperative Qmax or Qavg. RESULTS: A total of 17 patients with ED who underwent Rezum™ were identified, including 11 patients with an IPP. The median follow-up after Rezum™ was 65 days. There were no significant differences in baseline demographics and clinical characteristics between patients with and without an IPP. Postoperative Qmax (10.9 mL/s vs 9.8 mL/s, p = 0.04) and Qavg (7.5 mL/s vs 6.0 mL/s, p = 0.03) were significantly higher in patients with an IPP compared to patients without an IPP. There were no factors associated with postoperative Qmax or Qavg on linear regression. Two patients without an IPP went into urinary retention, while no complications occurred in IPP patients. CONCLUSION: Rezum™ is a safe and effective procedure to perform in ED patients, particularly those with an IPP. IPP patients may experience greater increase in uroflowmetry rate compared to ED patients without an IPP.
