[Perinatal outcomes of twin pregnancies conceived through in vitro fertilization versus spontaneous]. / Resultados perinatales de las gestaciones gemelares concebidas mediante fecundación in vitro versus espontáneas.

OBJECTIVE: Determine maternal and fetal characteristics of in vitro fertilization twin pregnancies in comparison with spontaneous twin pregnancies. MATERIAL AND METHODS: Retrospective historical cohort study between 2011 and 2013. Statistical analysis was performed with SPSS 15.0 program and Epidat 3.0. A value of p<0.05 was considered statistically significant. RESULTS: 96 twin pregnancies met inclusive criteria with an incidence of 2.01%, of which 54.16% were spontaneous twin pregnancies and 45.83% in vitro fertilization twin pregnancies. Mean maternal age at delivery was higher in vitro fertilization twin pregnancies (p=0.004). The primigravidae were more frequent in vitro fertilization twin pregnancies group (p<0.001). Monochorionic pregnancies percentage was superior in spontaneous pregnancies (p=0.009). Amenorrhea at delivery was not a significant difference between cohorts (p=.9). Preterm rate was superior in spontaneous twin pregnancies group (p=0.003). However, "great preterm deliveries" were higher in in vitro fertilization twin pregnancies (p<0.001). Significant differences were not observed in fetal presentation at delivery, first-born child birth-weight or intrauterine growth retardation between the two groups. Nevertheless, the mean birth-weight of second-born spontaneously conceived twins was higher than second-born twins of the in vitro fertilization conceived group (p=0.027). Gestational pathology presented the same distribution in both cohorts. There was no significant difference in the mode of delivery between the two groups. Total perinatal mortality rate was 20,83%o and comprised 2 first born twins and 2 second born twins. Three of the stillbirths came from the spontaneous pregnancies group and one from the in vitro fertilization group. CONCLUSIONS: Perinatal death was secondary to stillbirths, which we found higher in spontaneously conceived twin pregnancies due to higher number of monochorionic pregnancies.

[Diagnostic hysteroscopy indications and results in Complexo Hospitalario Universitario De Ourense]. / Indicaciones y resultados de la histeroscopia diagnóstica ambulatoria en el Complexo Hospitalario Universitario de Ourense.

BACKGROUND: Diagnostic hysteroscopy is an endoscopic technique that allows the evaluation of the endocervical canal and uterine cavity. OBJECTIVE: To evaluate indications, complications and referral to operative hysteroscopy. To analyze the correlation between sonographic display, hysteroscopy findings and histological diagnosis. MATERIALS AND METHODS: Retrospective and descriptive study of 904 patients who underwent diagnostic hysteroscopy between January 1, 2008 and June 30, 2012. RESULTS: The most frequent indication was sonographic detection of endometrial polyps (75% were premenopausal and 71.2% postmenopausal). The complication rate associated with the test was 11.4%. The reduction experimented in operative hysteroscopies was from 31.2% in 2008 to 12.2% between January and June 2012. When a polyp or a myoma was detected by sonography, diagnostic hysteroscopy showed them in 64.4% y 62.5% of the cases, respectively. The correlation between hysteroscopic findings and histopathologic diagnosis was 77.7% for normal endometrium, 77.9% for polyps, 17.8% for hyperplasic appearance and 100% for carcinoma suspicion. CONCLUSIONS: Diagnostic hysteroscopy is a safe technique that allows small interventions avoiding operative hysteroscopies. There is a good relation between hysteroscopic visual inspection and anatomopathologic diagnosis, but biopsy should be taken except if normal endometrium is visualized.

[Complete uterine ruptures]. / Roturas uterinas completas.

BACKGROUND: Uterine rupture is one of the most severe Obstetric complications by high morbidity and maternal and fetal mortality. OBJECTIVES: To review cases of uterine rupture occurred for the last five years. Release the incidence, the risk factors and maternal and fetal complications, both immediate and long term. METHODS: Retrospective cohort study including all patients who completed their gestation in the University Hospital Complex of Ourense (Spain) between 2008 and March 2013. Review all medical records of patients diagnosed with uterine rupture during this period. Statistical analysis was performed using the statistical package Epidat 3.0. RESULTS: We found an overall incidence of uterine rupture of 0.078 %. In patients with a previous cesarean delivery incidence rises to 0.31%. CONCLUSION: Uterine rupture is an uncommon but with high maternal fetal morbidity. The main risk factor is a trial of labor after a previous cesarean delivery.
