[Comparative study of overactive bladder prevalence in patients younger than 50 years with and without hyperprolactinemia]. / Estudio comparativo de la prevalencia de vejiga hiperactiva en pacientes menores de 50 años con y sin hiperprolactinemia.

OBJECTIVE: To determine if the hyperprolactinemia is associated with idiopathic overactive bladder. PATIENTS AND METHODS: We performed a transversal and analytic two groups study. We included all the patients whom plasma levels of prolactin were measured in the National Institute of Perinatology from March 1st to May 31, 2005 and fulfilled the selection criteria. To all these patients we applied a questionnaire of eight questions for the overactive bladder diagnostic. We used chi square statistical technique to establish if hyperprolactinemia is associated with the overactive bladder. RESULTS: One hundred sixty years patients were studied, establishing a relative prevalence of 2.82 (IC 95%: 1.45-3.17), determining association between the variables. CONCLUSIONS: hyperprolactinemia is associated with overactive bladder.

[Functional changes in urethra secondary to partum vs cesarean section. Evidence with dynamic perfilometry]. / Cambios funcionales en la uretra secundarios al parto vs cesárea. Demostración con la perfilometría dinámica.

BACKGROUND: The vaginal delivery produces anatomic and functional disease in the pelvic floor. The urethral profilometry, part of urodynamic study, represents graphically the urethral functionality. OBJECTIVE: To determine the functional changes in the dynamic profilometry in women with antecedent of vaginal delivery or cesarean section. PATIENTS AND METHOD: This is a correlation transversal study of 310 urodynamic studies in the Uroginecology Coordination, National Institute of Perinatology at 2003. RESULTS: We found a statistically significant correlation between vaginal delivery and urethral close area and the continence area, determining that a higher number of vaginal deliveries is associated with lower urethral close area and lower continence area.

[Umbilical artery thrombosis. A report of a case and review of the literature]. / Trombosis de la arteria umbilical. Comunicación de un caso y revisión de la bibliografía.

The thrombosis of the umbilical vessels is associated to high prenatal mortality. The arterial occlusion can compromise the maternal-fetal circulation with the neonatal death. Only two cases are reported in the literature with antepartum diagnosis and neonatal survival. We present the case of a 24 years old primigravida patient at 35 weeks normal pregnancy who was admitted in the hospital for diminution of the fetal movement's perception. The diagnosis was made with Doppler ultrasound of umbilical vessels in biophysical fetal evaluation; we decided pregnancy interruption with cesarean surgery. Cesarean delivery produced a male with Apgar scores of 8-9 at 1 and 5 minutes respectively, who was discharged one week later without vital compromise.
