AIM To investigate the development and behaviour of low-birthweight (LBW) term infants compared with matched term infants of appropriate birthweight (ABW). METHODS Two parallel cohorts of LBW infants (1500-2499 g) and ABW controls (3000-3499 g) were enrolled at birth in northeast Brazil. At 8 y, 164 children were assessed using clinical and psychological(More)
AIM To investigate the relation between head growth at different periods and IQ at 8 years, and to identify factors associated with more rapid head growth. METHOD Two parallel cohorts of term low birthweight (LBW) and appropriate birthweight (ABW) infants were enrolled at birth in northeast Brazil. Anthropometric measurements were made at birth, 2 months,(More)
This study analyzed the effectiveness of weekly iron supplementation on hemoglobin concentration, nutritional status, and mental and motor development of infants at four public daycare centers in Recife, Pernambuco State, Brazil.

Clinical, cytogenetic, pathologic, and histocompatibility-Y (H-Y) antigen studies were performed on a phenotype female with primary amenorrhea and streak gonads. Pathological examination of tissues removed at total hysterectomy and bilateral salpinog-gonadectomy showed gonadoblastoma and dysgerminoma of left streak. A single F-body (Y chromosome) was found(More)
