OBJECTIVES: To determine the incidence and neonatal outcomes of asymptomatic bacteriuria in pregnant women at high altitude. DESIGN: Comparative and prospective study. SETTING: EsSalud’s Southeast national hospital. PARTICIPANTS: Three hundred pregnant women with singletons. INTERVENTIONS: Midstream urine samples for culture were taken from women who had prenatal control at our hospital from January 2002 through December 2004. MAIN OUTCOME MEASURES: Asymptomatic bacteriuria and neonatal outcome. RESULTS: The incidence of asymptomatic bacteriuria was 17,7%. The most common uropathogen isolated was Escherichia coli (71,7%). History of preterm delivery and urine culture in the first trimester showed statistical significance (p< 0,05). Maternal age, route of delivery, weight, gender, gestational age, newborn’s Apgar during the first and fifth minute, relationship between newborn weight a...

The cystic adenomatous malformation (CAM) is a rare fetal lung lesion. Its frequency is about 1 in 4000 births and is characterized by an overgrowth of terminal respiratory bronchioles that form cysts of various sizes. It can be associated with polyhydramnios and pulmonary hypoplasia. We describe here a case of prenatal diagnosis and management of CAM at 3400 m (Cusco).
