BACKGROUND/AIMS Intrahepatic cholestasis of pregnancy is a rare disease of unknown etiology, with a strikingly higher prevalence in Chile than in most other countries. Although several studies suggest that a genetic predisposition is involved in the pathogenesis, no genetic disease-marker has so far been identified. Using a recently developed HLA-genotyping(More)
Tacrolimus and sirolimus are commonly used maintenance immunosuppressants in kidney transplantation. As their effects on immune cells and allograft molecular profiles have not been elucidated, we characterized the effects of tacrolimus to sirolimus conversion on the frequency and function of T cells, and on graft molecular profiles. Samples from renal(More)
Capronor, a single-capsule, biodegradable, subdermal contraceptive that releases levonorgestrel over a 12- to 18-month period, has been evaluated in 48 healthy women, ages 18 to 40 years. Sixteen participants received a 2.5 cm capsule (12 mg of levonorgestrel), and 32 received a 4.0 cm capsule (21.6 mg of levonorgestrel). Serum levonorgestrel levels were(More)

The aim of this study was to know if cholecystectomy rates have decreased in young women, considering that these rates have decreased in the last years in the general chilean population. The frequency of previous cholecystectomy was compared in 1582 women aged 23.9 +/- 5.8 years admitted to a maternity for delivery between 1985 and 1986 and 4943 women aged(More)
The purpose of this study was to evaluate the effect of verapamil administration on Human Fetuses in High Risk Pregnancies (FHRP) by Proton Magnetic Resonance Spectroscopy (HMRS) after Lactate identification. Two HMRS studies were performed on a 1.5 Tesla system using the body RF coil: the first one was done between 30-31 weeks of gestation and the second(More)
