Transcutaneous bilirubin in exclusively breastfed healthy term newborns up to 12 days of life.

Objective: To determine the curve of transcutaneous bilirubin in breastfed term neonates up to 12 days of life.

Methods: In a prospective cohort study, we performed a 12-day evaluation of 223 healthy, exclusively breastfed, appropriate-for-gestational-age neonates who roomed-in for at least 48 hours. Each newborn had forehead transcutaneous bilirubin and body weight measured at the end of 1, 2, 3, 4, 5, 6, 8, 10, and 12 days.

Public conceptions of schizophrenia in urban Brazil : symptom identification and causal attributions.

Objective: Little is known about public conceptions of mental disorders in Latin America and the Caribbean. The aim of this article is to assess how the population identifies symptoms of schizophrenia and the causes attributed to this disorder in the city of São Paulo, Brazil.

Method: A household survey was carried out in 2002 with a probabilistic sample of 500 individuals, residents of São Paulo with ages ranging from 18 to 65.

Strict guideline reduces the need for RBC transfusions in premature infants.

The aim of this study was to verify if the adoption of a strict guideline would reduce the need for red blood cell transfusions in the first 28 days of life in very low birth weight preterm infants. Retrospective study of two cohorts of very low birth weight infants transfused according to neonatologist decision (Period 1) or according to a strict guideline for erythrocytes transfusion (Period 2). Clinical and hematological data of 80 premature infants transfused in both periods of the study were obtained by chart review.

Exposure to marijuana during pregnancy alters neurobehavior in the early neonatal period.

Objective: To assess the neurobehavior of full-term neonates of adolescent mothers exposed to marijuana during pregnancy.

Study Design: This prospective cross-sectional study included full-term infants within 24 to 72 hours of life born to adolescent mothers at a single center in Brazil. Data on sociodemographic and obstetrical and neonatal characteristics were collected.

Salivary cortisol as an indicator of adrenocortical function in healthy infants, using massage therapy.

Context And Objective: The evaluation of adrenocortical function with the use of therapeutic massage has been little studied in Brazil. The purpose of this study was to evaluate the salivary cortisol levels before and after Shantala massage therapy on healthy infants.

Design And Setting: Prospective case series, in a public nursery, in São Paulo.

Role of beta2-glycoprotein I, LDL-, and antioxidant levels in hypercholesterolemic elderly subjects.

The levels of electronegative low-density lipoprotein (LDL-), LDL cholesterol oxidability, and plasma levels of molecular antioxidants and of beta(2)-glycoprotein I (beta(2) GPI) were studied in a group of 10 hypercholesterolemic (HC) and 10 normocholesterolemic (NC) elderly subjects. HC subjects showed significantly higher levels of cholesterol, LDL cholesterol, LDL-, and beta(2)GPI than NC, whereas high-density lipoprotein cholesterol and alpha-tocopherol levels were lower in HC as compared with NC subjects. Correlations among LDL- levels, LDL oxidation lag time, beta(2)GPI, and antioxidant plasma levels were studied in 100 HC elderly subjects.

Reliability of two behavioral tools to assess pain in preterm neonates.

Context: One of the main difficulties in adequately treating the pain of neonatal patients is the scarcity of validated pain evaluation methods for this population.

Objective: To analyze the reliability of two behavioral pain scales in neonates.

Type Of Study: Cross-sectional.

Antenatal treatment with corticosteroids for preterm neonates: impact on the incidence of respiratory distress syndrome and intra-hospital mortality.

Context: Although the benefits of antenatal corticosteroids have been widely demonstrated in other countries, there are few studies among Brazilian newborn infants.

Objective: To evaluate the effectiveness of antenatal corticosteroids on the incidence of respiratory distress syndrome and intra-hospital mortality among neonates with a gestational age of less than 34 weeks.

Type Of Study: Cross-sectional.

Studies on functional and morphological aspects in human multinodular simple goiter tissues.

Samples from 2 different locations within the same euthyroid multinodular goiters (SMG) and normal (N) human thyroids were assayed for their content of DNA, thyroglobulin (Tg), and stable iodine (1), and determined the response of adenosine 3',5'-cyclic monophosphate (cAMP) to TSH and NaF. Quantitative morphological estimation of histological components in the thyroid was performed and correlated with functional parameters. Regardless the zonal evaluation, in SMG the mean (± SD) DNA content (⧎g/mg tissue) (1.
