RESUMO

Virility and sexual pleasure have long been associated with penile size and this, in turn, has typically been linked to some anthropometric measurements, such as foot size or height, leading to various misconceptions from both men and women. Our intention is to estimate penile size parameters in Argentina and evaluate the correlation between penile size and certain anthropometric measurements. This is a cross-sectional, descriptive, multicenter, and observational study. Male patients who underwent a urological procedure were included in four hospitals located in different regions of the country. Different anthropometric measurements were obtained: height, weight, penile circumference, flaccid and stretched length, and foot length. A total of 800 patients were evaluated. Mean left foot was 26.4 cm. Mean flaccid penile length was 11.4 (95% confidence interval [CI]: 8-14) cm, and mean penile circumference was 10.1 (95% CI: 8-12) cm. Finally, mean stretched penis was 15.2 (95% CI: 11-18.5) cm. We can confirm that estimates of the average penile measurements in Argentina are flaccid penis length of 11.4 cm, penile circumference of 10.1 cm, and stretching the penis to the maximum in flaccidity of 15.2 cm. Correlations between flaccid penis length, stretched out, penile circumference, height, weight, and length of the left foot were evaluated, finding low or no correlation between those mentioned, except for flaccid and stretched length.

RESUMO

Objetivo: El objetivo de este trabajo es analizar los hallazgos en resonancia magnética testicular (RMt) y el tipo histopatológico de las lesiones para determinar qué características relacionadas con las imágenes pueden constituir predictores de malignidad.Materiales y métodos: Se analizaron de manera retrospectiva 46 pacientes con lesiones testiculares, a quienes se evaluó inicialmente con ultrasonido (US) y luego con RMt empleando un equipo de 1,5 teslas. Los estudios de resonancia magnética (RM) fueron analizados por un radiólogo con 8 años de experiencia en RMt. Los hallazgos en las imágenes como el tamaño de la lesión, la intensidad de señal en secuencias T1, T2, y el realce tras la administración de contraste se correlacionaron con el diagnóstico de anatomía patológica (AP). Se estudió la sensibilidad, la especificidad, el valor predictivo positivo (VPP) y el valor predictivo negativo (VPN).Resultados: El realce tras administración de contraste fue el hallazgo de mejor performance con una sensibilidad, especificidad, VPP y VPN de 90 (71-97), 47 (24-71), 74 (56-87) y 73 (40-92), respectivamente. Los resultados para las lesiones hiperintensas, hipointensas o heterogéneas en secuencias ponderadas en T2 y con realce con el contraste endovenoso fueron de 87 (49-84), 47 (44-89), 74 (55-86) y 67 (35-89), respectivamente (sensibilidad, especificidad, VPP y VPN).Conclusión: El hallazgo de una lesión testicular de baja intensidad de señal y/o heterogénea en secuencias T2, con realce con contraste EV representa un valioso predictor de malignidad. Siendo esta última característica la más sensible como predictor de malignidad en las imágenes. (AU)


Purpose: The purpose of our study is to analyze the imaging findings described in MRI and the histopathologic type of testicular lesions to determine which findings are the best predictors of malignancy.Materials and methods: Forty six (46) patients with testicular lesions were initially studied with ultrasound (US) and with testicular MRI (tMRI) on a 1.5-T magnet. MRIs were reviewed by a radiologist with 8 years of experience and imaging findings such as the size of the lesion, the signal intensity in T1, T2 weighted sequences, and the enhancement after endovenous contrast administration, were correlated with the histopathologic diagnosis. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were analyzed.Results: The enhancement after administration of contrast was the finding of better performance with a sensitivity, specificity, PPV and NPV of 90 (71-97), 47 (24-71), 74 (56-87) and 73 (40-92), respectively. Meanwhile, the results for hypointense/heterogeneous lesions in T2 weighted sequences and with enhancement with intravenous contrast were 87 (49-84), 47 (44-89), 74 (55-86) y 67 (35-89), respectively.Conclusion: The finding of a testicular lesion of low signal intensity and heterogeneous in T2 weighted sequences, with IV contrast enhancement represents a valuable predictor of malignancy. The latter being the most sensitive as a predictor of malignancy. (AU)

RESUMO

INTRODUCCIÓN: existe una gran variedad de tratamientos orales para la Enfermedad de La Peyronie (EP), pero ninguno demostró ser efectivo. En los últimos años se ha propuesto a la Pentoxifilina (PTX) como un potencial agente para su tratamiento. OBJETIVO: evaluar la evolución clínica de los pacientes que recibieron PTX al menos 3 meses durante la fase aguda de la EP. MATERIALES Y MÉTODOS: estudio de cohorte retrospectivo y observacional. Los datos se obtuvieron de las historias clínicas de pacientes con diagnóstico de EP entre enero y octubre de 2017. Para la evaluación objetiva, se utilizaron autofotografías y técnica de Kelami. RESULTADOS: 93 hombres cumplieron con los criterios de inclusión. El tiempo medio de tratamiento con PTX fue de 7,9 meses, y el de seguimiento, 10,8 meses. El 59,1% de los pacientes no tuvo modificaciones en su curvatura, el 9,7% mejoró, mientras que el 31,2% empeoró. De 49 pacientes que penetraban sin dificultad, 34 (69,4%) no tuvieron cambios, 12 (24,5%) pasaron a tener dificultad y 3 (6,1%) se convirtieron en no penetradores (p 0,0001). De los 41 pacientes que tenían dificultad en la penetración, 13 (31,7%) pudieron penetrar sin dificultad, 7 (17,1%) pasaron a no poder hacerlo, mientras que el resto (21 pacientes) se mantuvo sin cambios (p 0,0001). La correlación entre la curvatura inicial y la curvatura luego del tratamiento medido en todos los pacientes fue significativa (p 0,028). CONCLUSIÓN: la PTX podría tener un efecto positivo en estabilizar la enfermedad, y los hombres con EP en fase aguda podrían beneficiarse con el tratamiento.


INTRODUCTION: There is a wide variety of oral treatments for Peyronie's Disease (PD) but none proved to be effective. In recent years, Pentoxifylline (PTX) has been proposed as a potential agent for the treatment. Objective: To evaluate the clinical evolution of patients who received PTX at least 3 months during the acute phase of PD. MATERIALS AND METHODS: Retrospective and observational cohort study. The data were obtained from the clinical records of patients diagnosed with PE between January 2007 and October 2017. For their objective evaluation, autographs and the Kelami technique were used. RESULTS: 93 men met the inclusion criteria. The mean time of treatment with PTX was 7.9 months and the follow-up time was 10.8 months. 59.1% of patients had no changes in their curvature, 9.7% improved, while 31.2% worsened. Of 49 patients who entered without difficulty in penetrating, 34 (69.4%) had no changes, 12 (24.4%) had difficulty and 3 (6.1%) became non-penetrators (p 0.0001). Of the 41 patients who had difficulty in penetrating, 13 (31.7%) could penetrate without difficulty, 7 (17.1%) were unable to do so, while the rest (21 patients) remained unchanged (p. 0.0001). The correlation between initial curvature and curvature after treatment measured in all patients was significant (p 0.028). CONCLUSION: PTX could have a positive effect in stabilizing the disease and men with acute phase PE could benefit with treatment.

RESUMO

Objetivos: los inhibidores de fosfodiesterasa revolucionaron el tratamiento de la disfunción eréctil. Las ondas de choque de baja intensidad emergen como una alternativa terapéutica no invasiva. Materiales y métodos: estudio de cohorte prospectiva y observacional, en el que se evaluó la respuesta de 17 pacientes sexualmente activos al tratamiento con ondas de choque de baja intensidad a los 3 y 6 meses, mediante el Indice Internacional de Función Eréctil (IIEF-6), las preguntas 2 y 3 del Sexual Encounter Profile (SEP-2 y SEP-3), y el Erection Hardness Score (EHS) para evaluar la rigidez peneana, así como una evaluación de satisfacción global con el tratamiento (GAQ) y de recomendación del mismo. Resultados: 6 pacientes presentaban disfunción eréctil leve y 11 disfunción eréctil moderada-severa. Ambos grupos mostraron diferencias estadísticamente significativas en el IIEF-6, SEP-2, SEP-3 y EHS, a los 3 y 6 meses. Sin embargo, no todos los pacientes se mostraron satisfechos o recomendarían el tratamiento, sobre todo en aquellos con disfunción eréctil moderada-severa previo al tratamiento. Conclusión: las ondas de choque de baja intensidad son un tratamiento emergente para la disfunción eréctil, aunque aun sin evidencia clara de su eficacia e indicaciones. Los dispares resultados de los grupos se han debido probablemente a la heterogeneidad de las condiciones basales de los pacientes.(AU)


Objectives: Iphosphodiesterase inhibitors revolutionized the treatment of erectile dysfunction. Low intensity shockwave therapy emerge as a non-invasive therapeutic alternative. Materials and methods: this was a prospective and observational study, in which 17 sexually active patients were evaluated 3 and 6 months after treatment with low intensity shockwave therapy, using the International Index of Erectile Function (IIEF-6), questions 2 and 3 of the Sexual Encounter Profile (SEP-2 and SEP-3), and the Erection Hardness Score (EHS) to assess penile rigidity, as well as a global satisfaction evaluation with the treatment (GAQ) and if they would recommend it to others. Results: 6 patients showed mild erectile dysfunction and 11 moderatesevere erectile dysfunction. Both groups showed statistically significant differences in IIEF-6, SEP-2, SEP-3 and EHS, after 3 and 6 months. However, not all of them were satisfied with the treatment or would recommend it to others, especially those with moderate-severe basal erectile dysfunction. Conclusion: low intensity shockwave therapy is an emergent treatment for erectile dysfunction, although there is no sufficient evidence of its efficacy and indications. The differences between groups were due probably to the heterogeneity of the basal conditions of the patients.(AU)

RESUMO

El virus del papiloma humano (VPH) es una de las enfermedades de transmisión sexual más comunes. Puede afectar tanto el aparato genital masculino y femenino, como también el área perianal, ano, y diversas áreas de cabeza y cuello y otorrinolaringológicas, ya sea como lesiones benignas o como promotor de lesiones malignas. Las lesiones benignas por VPH en genitales masculinos se caracterizan fundamentalmente por la aparición de lesiones verrugosas, aunque también puede manifestarse mediante lesiones planas atípicas. En algunos casos hay ausencia de lesiones macroscópicamente visibles que pueden hacerse evidentes con la prueba de ácido acético. La biopsia de la lesión, su evaluación anatomopatológica y, sobre todo, la determinación de la existencia y el tipo de virus involucrado mediante PCR (reacción en cadena de la polimerasa) permiten confirmar el diagnóstico. En algunas ocasiones es necesario realizar una cistoscopia para diagnosticar lesiones intrauretrales y vesicales. Los tratamientos propuestos son muy variados y de eficacia dispar, desde las topicaciones y la electrocirugía o la criocirugía, hasta el empleo de la tecnología láser. La prevención con el uso de protección durante el acto sexual así como la educación sexual son fundamentales. En los últimos 10 años se ha implementado el uso de la vacuna para el VPH en niñas con el fin de disminuir la incidencia de lesiones de alto grado y de cáncer de cuello uterino, pero su indicación en varones es menos clara y aún no ha sido consensuada. (AU)


Human papiloma virus (HPV) is one of the most common sexual transmitted diseases. It can affect the male genitalia, as well as the perianal and anal regions and multiple areas of the head and neck and otorhinolaryngological structures, as benign lesiones or as a promoter of malignant lesions. Benign male genitalia lesions are characterized mainly by verrucous lesions, although flat atypical lesions can be found, as well as the abscence of macroscopic visible lesions that in some cases can become evident using the acetic acid test. Lesion biopsy, its histological evaluation, and the determination of the existence and type of virus using PCR (Polymerase Chain Reaction) can confirm the diagnosis. In some cases is necessary to do a cistoscopy to diagnose intraurethral and vesical lesions. Proposed treatments are varied and with a wide range of efficacy, from topications to electro or cryosurgery, and the use of laser technology. Sexual education and the use of sexual protection are essential in prevention. In the last 10 years the use of VPH vaccine in girls was widely spread, in order to decrease the incidence of high grade lesions and cervix cancer. Its indication in male patients is less clear and not yet consented among specialists. (AU)
