    Infantile/Capillary Hemangioma of the Uterine Corpus: A Rare Cause of Abnormal Genital Bleeding
    (2022) Ralph, Constanza; Cuello, Mauricio A.; Merino, Paulina M.; De Barbieri, Florencia M.; Astudillo, Katya; Huete, Alvaro; Garcia, Cristian; Pomes, Cristian
    Background: Infantile hemangiomas are vascular anomalies. However, they rarely cause genital bleeding. Here, we present the case of a young female with an endocavitary hemangioma who presented with abnormal uterine bleeding (AUB).Case: The patient was an 8-year-old female with genital bleeding. Transabdominal pelvic ultrasound showed a 20-mm highly vascularized focal intrauterine endocavitary lesion. Vascular computerized tomography excluded vascular anomalies. Magnetic resonance imaging sug-gested a hemangioma. Minimally invasive open surgery was performed to remove the lesion. Subsequent pathology analyses confirmed an infantile/capillary hemangioma. Conclusions: Infantile hemangiomas are vascular anomalies that should be considered potential causes of AUB in early puberty. The study of these cases should include pelvic ultrasound and vascular magnetic resonance imaging. Experienced surgeons can successfully accomplish fertility-sparing surgical procedures. Summary: We describe an unusual case of peripubertal AUB caused by an endocavitary capillary hemangioma. Management included fertility-sparing surgery and the complete resolution of symptoms.

    Influencia combinada del índice de masa corporal pregestacional y de la ganancia de peso en el embarazo sobre el crecimiento fetal
    (SOC MEDICA SANTIAGO, 2011) Mardones, Francisco; Garcia Huidobro, Trinidad; Ralph, Constanza; Farias, Marcelo; Dominguez, Angelica; Rojas, Ivan; Teresa Urrutia, M.
    Background: The Chilean Ministry of Health has been using standards for nutritional evaluation and weight gain recommendations during pregnancy in the last 25 years. In the meantime new standards have been developed. Aim: To study the combined influence of preconception maternal nutritional status and gestational weight gain, using new standards to classify those parameters, on perinatal outcomes. Material and Methods: A cohort of 11,465 healthy pregnant women was prospectively followed until term. Their pre-gestational nutritional status was classified using the body mass index cut-offs in use in the United States (USA). Their gestational weight gain was classified using categories proposed in a Danish study. Perinatal outcomes included were risky birth weight, i.e. < 3000 g and >= 4000 g, and cesarean delivery Relative risks for those perinatal outcomes were calculated for all combined categories of pre-gestational nutritional status and gestational weight gain. Results: Relative risks of almost all gestational weight gain results were statistically significant for women having a normal pre-gestational nutritional status meanwhile all of them were not significant for underweight women. Overweight and obese women had similar relative risks values as normal women. However, many of them were not significant, especially in obese women. Conclusions: There is an independent and combined influence of preconception nutritional status and gestational weight gain on perinatal outcomes, when using standards to classify those parameters developed in the USA and Denmark, respectively (Rev Med Chile 2011; 139: 710-716).
