La morbilidad materna extrema constituye una condición grave que compromete la vida y el bienestar de las mujeres gestantes; en ese contexto, el estudio tuvo como objetivo determinar las características epidemiológicas y clínicas de los casos registrados en el Instituto Nacional Materno Perinatal durante el período 2017–2022. Se desarrolló una investigación con enfoque cuantitativo, diseño observacional, descriptivo y retrospectivo, que incluyó a la totalidad de gestantes notificadas como casos de morbilidad materna extrema según los criterios de la Organización Mundial de la Salud, mediante un muestreo censal no probabilístico. El análisis se realizó mediante estadística descriptiva, utilizando medidas de tendencia central y dispersión para variables cuantitativas, así como frecuencias absolutas y relativas para variables cualitativas.

Objectives. To determine the relationship between obesity at the beginning, in the second and third trimester of pregnancy and macrosomic newborns treated at the National Maternal Perinatal Institute during the period from 2003 to 2005. Materials and methods. An analytical, prospective study in which it was followed two cohorts of pregnant women, the first one with 210 pregnant with adequate prepregnancy weight or overweight; and the second one with 211 pregnant with prepregnancy maternal obesity. We proceeded to descriptive analysis, through percentages, means and standard deviations. For the determination of hypothesis tests proceeded to significant inferential statistics with an alpha level of statistical significance of less than 0.05. To determine the influence, it proceeded to use the Relative Risk (RR) with confidence intervals at 95%.

Interstitial ectopic pregnancy, misnamed cornual, is a rare pathology, but it implies a high morbidity and mortality if it is notdiagnosed and treated on time. We present the case of a one-year-old patient who attended the emergency room due topain, vaginal bleeding, and a 9-week period of amenorrhea. During the ultrasonographic evaluation, a gestational sac withan active embryo was evidenced at the level of the right uterine horn, for which the diagnosis of cornual ectopic pregnancywas considered and proceeding to perform an abdominal hysterectomy. The best knowledge of the natural history of thedisease, as well as an early and timely diagnosis, is the key to the conservative management of this disease.

Objective. To describe the psychological, social and gynecological characteristics of patients with gestational lossseen at the Instituto Nacional Materno Perinatal (2022). Materials and Methods. This research corresponds to aretrospective descriptive observational study, in which 176 clinical histories of patients with gestational losses duringthe year 2022 attended by the psychology service who met the inclusion and exclusion criteria were collected.

Objective. To evaluate the changes that have occurred from 2012 to 2017, and analyze the factors that influence them. Materials and Methods. The maternal-perinatal statistical database managed by the National Maternal Perinatal Institute was analyzed. All those births belonging to Metropolitan Lima, born alive, of single births were included, obtaining a total of 107,581 deliveries. A multivariate analysis was performed adjusting for different obstetric and socioeconomic variables. Results. There were no significant changes in Low Birth Weight, Preterm Birth and PEG between the different years. In all three cases, mild anemia is playing as a protective factor 0.91 (0.74-1.1), 0.80 (0.72-0.90) and 0.85 (0.76-0.95), respectively.

Intrauterine fetal growth restriction (IUGR), is a clinical circumstance in which the fetus does not express its genetic growth potential and as a final result there is a decrease in body weight, which is below the 10th percentile for gestational age on a selected growth curve. The global prevalence of IUGR according to different authors varies between 3,7% and 22,4%. In Peru they are reported from 4,8% to 10,1%. Obstetric factors associated with IUGR include: pre-eclampsia with OR=1,69 to OR=66,54; anemia during pregnancy OR=2,18 to OR=9,70; Previous IUGR with OR=3,26 at OR=14,49 and preterm delivery with OR=3,58 at OR=14,60.

Postmenopausal women in the presence of abnormal uterine bleeding spontaneously and unexpectedly requires rigorous evaluation to determine the source of the bleeding. The most common cause of postmenopausal bleeding is endometrial atrophy and endometrial polyp; however, must be ruled endometrial cancer is the cause in about 10 percent of patients. The gold standard for evaluating the endometrium is transvaginal ultrasonography and endometrial biopsy, which are two key components that help reach an accurate diagnosis.
