BACKGROUND Asymptomatic bacteriuria occurs in 2% to 10% of pregnancies and, if not treated, up to 30% of mothers will develop acute pyelonephritis. Asymptomatic bacteriuria has been associated with low birthweight and preterm birth. OBJECTIVES To assess the effect of antibiotic treatment for asymptomatic bacteriuria on the development of pyelonephritis(More)
BACKGROUND Miscarriage occurs in 10% to 15% of pregnancies. The traditional treatment, after miscarriage, has been to perform surgery to remove any remaining pregnancy tissues in the uterus. However, it has been suggested that drug-based medical treatments, or expectant care (no treatment), may also be effective, safe and acceptable. OBJECTIVES To assess(More)
BACKGROUND Urinary tract infections, including pyelonephritis, are serious complications that can result in significant maternal and neonatal morbidity and mortality. There is a large number of drugs, and combination of them, available to treat urinary tract infections, most of them tested in non-pregnant women. Attempts to define the optimal antibiotic(More)
A successful operation on an infant with a tunnel through which the aorta communicated with the right ventricle is reported. The diagnosis was suspected preoperatively on the basis of two-dimensional Doppler color echocardiography and confirmed by cardiac catheterization. The aortico-right ventricular tunnel originated independently from the left coronary(More)
Bioartificial liver devices are alternative therapies for patients suffering from acute hepatic failure or metabolic defects. Here, we show a bioartificial device, developed with a cartridge used for pediatric hemofiltration and spheroids of porcine hepatocytes housed in the extracapillary space of the cartridge. The cartridge was attached to a robotic arm(More)
BACKGROUND Caesarean section increases the risk of postpartum infection for women and prophylactic antibiotics have been shown to reduce the incidence; however, there are adverse effects. It is important to identify the most effective class of antibiotics to use and those with the least adverse effects. OBJECTIVES To determine, from the best available(More)
BACKGROUND Mexico City is located at an altitude of 2240 meters (m) above sea level with a mean barometric pressure of 585 mmHg. Normal PaO2 and PaCO2 values in young subjects are 67 and 31 mmHg, respectively. Sleep desaturation, present in normal subjects at sea level, may be more frequent and severe at moderate altitudes. Our objective was to describe(More)
BACKGROUND Validated clinical indicators of sleep disordered breathing (SDB) in children are scarce and none generated at moderate altitude where hypoxemic complications could be frequent and oximetry evaluation might be very efficient. METHODS A total of 158 children consecutively referred to a sleep clinic in Mexico City (2240 m) for suspected sleep(More)
BACKGROUND Miscarriage occurs in 10% to 15% of pregnancies. The traditional treatment, after miscarriage, has been to perform surgery to remove any remaining placental tissues in the uterus ('evacuation of uterus'). However, medical treatments, or expectant care (no treatment), may also be effective, safe and acceptable. OBJECTIVES To assess the(More)
