[Anaemia in pregnancy and in the immediate postpartum period. Prevalence and risk factors in pregnancy and childbirth].

Introduction And Objective: The objective of the study was to assess the prevalence of anaemia in the immediate postpartum period (48-72hours), determine the risk factors and the value of haemoglobin before birth to reduce postpartum anaemia.

Material And Methods: A prospective, observational and longitudinal study that included 1,426 women who delivered consecutively and agreed to participate in the study. Different variables, analytical, epidemiological, foetal and maternal symptoms were studied.

p53 oncoprotein as a prognostic indicator in patients with breast cancer.

Unlabelled: p53 is a tumor suppressor gene located on the human chromosome 17 that is thought to regulate (suppress) the proliferation of normal cells. The mutant protein accumulates in the nuclei of tumor cells that may then have a proliferative advantage over normal cells. The purpose of this study was to investigate the relationship between levels of mutant p53 expression and the clinical outcome of patients with node-positive and node-negative breast cancer.

Administration of antibiotics to patients with rupture of membranes at term: a prospective, randomized, multicentric study. Collaborative Group on PROM.

Objective: To assess whether antibiotic administration changes the rate of materno-fetal infectious morbidity in premature rupture of membranes occurring later than 35 weeks of gestation.

Methods: A prospective, randomized and multicentric study in the Perinatology Units of eleven hospitals in Spain. Women were randomized to either antibiotic administration or control group.

Neonatal survival after preterm premature rupture of membranes secondary to first trimester chorionic villus sampling.

A case of preterm premature rupture of membranes (PROM) secondary to first trimester chorial biopsy is described. The newborn survived and physical and psychological development was normal at 1 year of age. On review of the literature, different attitudes may be found with regard to the treatment of PROM: some authors prefer expectant management while others defend extraction of the fetus when reasonable maturity is reached.
