Intercellular adhesion molecules and mortality for sepsis in infants younger than 1 year of life.

Background: Adhesion molecules in sepsis syndrome are correlated with the severity of illness and may be considered as predictors of survival outcome in adults. However, only few studies have been performed in infants and none using international criteria for sepsis.

Objective: To determine whether adhesion molecules during the first 7 days of the disease could predict sepsis outcome and its severity.

Renal function, renal volume, and blood pressure in infants with antecedent of antenatal steroids.

Steroids have been used for more than 20 years in preterm infants to induce pulmonary maturity; however, some long-term effects have been reported, such as insulin resistance and elevation of blood pressure. The aim of our study was to compare renal volume, renal function, and blood pressure in infants between 12-36 months of age with and without antecedent of antenatal steroid treatment. This was a cross-sectional study comprised of three groups of infants (n = 30, respectively): preterm infants with and without antecedent of receiving antenatal steroids, respectively, and full-term infants.

Daytime sleepiness and quality of life: are they associated in obese pregnant women?

Objective: To know the relationship between daytime sleepiness and quality of life during pregnancy according to the weight gain and baseline weight.

Methods: We studied 216 pregnant women (108 obese and 108 non-obese). At first and third trimester of pregnancy they completed the 12-item short-form health survey (SF-12) and the Epworth Sleepiness Scale (ESS).

Iron overload as cardiovascular risk factor in children and adolescents with renal disease.

Background: Iron overload can affect cardiac structure and function by the production of free radicals in addition to iron deposits in heart muscle. The purpose of this study was to compare traditional and non-traditional cardiovascular risk factors (CVRF) in children and adolescents on renal replacement with and without iron overload. Also, we evaluated the relationships between iron overload and left ventricular mass (LVM).

[Holt-Oram syndrome and portal extrahepatic hypertension. A case report].

[Maternal mortality: relation between directive management and opportune clinical care].

The authorities of the High Medical Specialized Units (HMSUs) Obstetric/Gynecology Service (OB/GYN) and Intensive Care Unit (ICU) elaborated a strategy, which included the organization and interrelation of both hospital services and the implementation of an Epidemiologic Monitoring Program for all critical complicated pregnancies. This plan consisted in an assignment of personnel for special care, immediate communication with heads of services to coordinate the attention and to facilitate the resources for medical attention in these patients, as well as daily follow up by the authorities until complete resolution. Through epidemiological monitoring, 274 cases of pregnant women with high risk of mortality were identified during 2005, and 437 during 2006 (increased 59 %).

Left ventricular mass and heart sympathetic activity after renal transplantation in children and young adults.

Recent studies considered that an increase in sympathetic activity (SA) may be responsible for left ventricular hypertrophy (LVH). Before and after renal transplantation (RT), we evaluated changes on left ventricular mass (LVM) and SA in 40 end-stage renal disease patients between 8 and 35 years old. Hypertension (95.
