[Complete androgen insensitivity syndrome: diagnosis and multidisciplinary management]. / Síndrome de insensibilidad completa a los andrógenos: diagnóstico y manejo multidisciplinario.

Background: Complete androgen insensitivity syndrome (CAIS) is a sexual differentiation disorder, caused by a defect in the androgen receptor gene (AR; OMIM# 313700). It is characterized by the resistance of target tissues to the action of testosterone, which prevents normal male genital development. The objective is to describe a family case of CAIS and highlight the importance of multidisciplinary medical management and early diagnosis of this syndrome. Clinical case: We present two cases of SICA in a Mexican family. Case 1: 18-year-old female patient with primary amenorrhea and a history of surgery at an early age, without performing gonadectomy. Case 2: 11-year-old female patient who, due to the history of her sister, underwent surgery at that age. In both patients, absence of uterus and ovaries, hypoplastic vagina and male gonads is reported. The 46,XY karyotype was detected with the GTG and CBG band technique and fluorescent in situ hybridization with the presence of the Y chromosome in 100% of the cells analyzed. Although both patients were identified with their assigned sex, they were referred to the institution's psychiatric clinic. Conclusions: The importance of multidisciplinary management for the diagnosis of SICA at an early age is discussed, in order to make decisions regarding the treatment and management of patients, avoiding malignant transformation of the male gonads.

Introducción: el síndrome de insensibilidad completa a los andrógenos (SICA) es un desorden de la diferenciación sexual, causado por un defecto en el gen receptor de andrógenos (AR; OMIM# 313700). Se caracteriza por la resistencia de los tejidos diana a la acción de la testosterona, lo que impide el desarrollo genital masculino de manera normal. El objetivo es describir un caso familiar de SICA y destacar la importancia del manejo médico multidisciplinario y el diagnóstico temprano de este síndrome. Caso clínico: presentamos dos casos de SICA en una familia mexicana. Caso 1: paciente de 18 años con amenorrea primaria y antecedente de intervención quirúrgica a edad temprana, sin realizarle gonadectomía. Caso 2: paciente de 11 años que debido al antecedente de su hermana fue intervenida quirúrgicamente a esa edad. En ambas pacientes, se reporta ausencia de útero y ovarios, vagina hipoplásica y gónadas masculinas. El cariotipo 46,XY fue detectado con técnica de bandas GTG y CBG e hibridación in situ fluorescente con presencia del cromosoma Y en el 100% de las células analizadas. Aunque ambas se identificaban con su sexo de asignación, fueron referidas a consulta de psiquiatría de la institución. Conclusiones: se discute la importancia del manejo multidisciplinario para el diagnóstico de SICA a edades tempranas con la finalidad de tomar decisiones respecto al tratamiento y manejo de las pacientes y evitar la malignización de las gónadas masculinas.

Safety and efficacy of Vecchietti vaginoplasty in vaginal agenesis: cohort study. Medellín, Colombia 2007-2012 / Seguridad y eficacia de la vaginoplastia de Vecchietti en agenesia vaginal: estudio de cohorte, en Medellín, Colombia, 2007 a 2012

Objective: To describe the Vecchietti vaginoplasty technique (VVT) in patients diagnosed with secondary vaginal agenesis and to analyze the safety and efficacy of this technique. Materials and methods: Historical cohort of patients with vaginal agenesis secondary to Mayer- Rokitansky-Kuster-Hauser and androgen insensitivity syndromes, subjected to vaginoplasty using the Vecchietti technique at San Vicente Fundación University Hospital, a high complexity referral institution located in the city of Medellín, during the time period between 2007 and 2012. Patients with functional a vagina for intercourse were excluded. Sampling was consecutive. Sociodemographic, clinical, safety and efficacy variables were measured. Descriptive statistics were used. Results: The main complaint was primary amenorrhea (69.2%). Associated malformations included right renal agenesis (15.4%) and skeletal malformations (15.4%). There was one intra-operative bladder perforation and, postoperatively, there were three (23.1%) minor complications. At 1-year follow-up, a functional vagina had been obtained in 84.6% of cases. Conclusion: Vecchietti vaginoplasty is a simple surgical technique resulting in satisfactory functional outcomes with only minor complications. Further studies with control groups are required in order to better assess the efficacy of the various techniques used for neovagina creation.

γ-Oryzanol reduces caveolin-1 and PCGEM1 expression, markers of aggressiveness in prostate cancer cell lines.

BACKGROUND: Prostate cancer is a leading cause of death among men due to the limited number of treatment strategies available for advanced disease. γ-oryzanol is a component of rice bran, rich in phytosterols, known for its antioxidant, anti-carcinogenic and endocrinological effects. It is known that γ-oryzanol may affect prostate cancer cells through the down regulation of the antioxidant genes and that phytosterols have anti-proliferative and apoptotic effects. There are evidences showing that some of the components of γ-oryzanol can modulate genes involved in the development and progression of prostate cancer, as caveolin-1 (Cav-1) and prostate specific androgen-regulated gene (PCGEM1). METHODS: To determine the effects of γ-oryzanol on prostate cancer cell survival we evaluated the cell viability and biomass by MTT and sulforhodamine B assays, respectively. Cell death, cell cycle and pERK1/2 activity were assessed by flow cytometry. The changes in gene expression involved in the survival and progression of prostate cancer cav-1 and PCGEM1 genes were evaluated by quantitative real time reverse transcriptase polymerase chain reaction (RT-PCR) and cav-1 protein by immunofluorescence followed by confocal microscopy analysis. RESULTS: We found that γ-oryzanol decreases cell viability and culture biomass by apoptosis and/or necrosis death in androgen unresponsive (PC3 and DU145) and responsive (LNCaP) cell lines, and signals through pERK1/2 in LNCaP and DU145 cells. γ-oryzanol also appears to block cell cycle progression at the G2/M in PC3 and LNCaP cells and at G0/G1 in DU145 cells. These effects were accompanied by a down regulation in the expression of the cav-1 in both androgen unresponsive cell lines and PCGEM1 gene in DU145 and LNCaP cells. CONCLUSION: In summary, we used biochemical and genetics approaches to demonstrate that γ-oryzanol show a promising adjuvant role in the treatment of prostate cancer.

Síndrome de Morris / Morris Syndrome

Introducción: el síndrome de resistencia completa a los andrógenos, feminización testicular o síndrome de Morris, puede presentarse en uno de cada 20 000 a 64 000 recién nacidos varones. Objetivo: presentar un caso con genotipo masculino y fenotipo femenino dado por desarrollo mamario, con genitales externos femeninos con hipoplasia de los labios mayores y menores y la vagina muy corta que termina en un fondo de saco ciego. Métodos: se valora en la consulta a una paciente adolescente de 19 años de edad con amenorrea primaria y contacto sexual insatisfactorio (imposibilidad de penetración). Resultados: se comprueba al examen vagina rudimentaria de unos dos centímetros y escaso desarrollo de genitales externos. En los exámenes complementarios se comprueban cifras de testosterona y LH aumentadas, así como el estradiol disminuido y un cariotipo 46 XY por lo que se sospecha síndrome de Morris y se planifica intervención quirúrgica combinada en un tiempo (vaginal y abdominal) donde se realiza anexectomía total derecha por video laparoscopia y reconstrucción de vagina por técnica de Williams. Posoperatorio satisfactorio y seguimiento ulterior por consulta donde se comprueba vagina funcional y estabilidad emocional de la paciente. Conclusiones: el estudio anatomo-patológico comprueba la existencia de ovario y testículo en la muestra quirúrgica lo que confirma el diagnóstico de síndrome de Morris o de resistencia completa a los andrógenos

Introduction:the syndrome of complete androgen resistance, testicular feminization or Morris syndrome may occur in one in 20 000 to 64 000 of male newborns. Objective: to present a case with male genotype and female phenotype given by breast development, female external genitalia with hypoplasia of the labia and very short vagina ending in a blind pouch Methods: a 19 year- old female patient is assisted in consultation due primary amenorrhea and unsatisfactory sexual contact (impossibility of penetration). Results: at examination, we found a rudimentary vagina of about two inches and underdeveloped external genitalia. The exams confirmed increased LH and testosterone levels and decreased estradiol. It is also found a 46 XY karyotype, so Morris syndrome is suspected. Combined surgery is planned for the vagina and abdomen. Total videolaparoscopy right adnexectomy and vaginal reconstruction by technique of Williams are performed. We had satisfactory postoperative and subsequent follow-up consultation where functional vagina and emotional stability of the patient were checked. Conclusions: the pathological study verifies the existence of ovary and testis in the surgical specimen confirming the diagnosis of Morris syndrome or complete androgen resistance
