BACKGROUND The purpose of this study was to evaluate the secular trends in height, weight and weight/height of schoolchildren from the city of Paulínia, São Paulo, Brazil between 1979/80 and 1993/94. METHODS Anthropometric measurements (height, weight and weight/height) of 1,903 children (6.5-12.5 y); 51.5% M: 48.5% F, from Paulínia public schools were(More)
Villa IAPI is a poor neighborhood of about 5,000 inhabitants in the overpopulated conurbano bonaerense at the outskirts of the city of Buenos Aires. Most of the adult male residents are construction workers; the rest are temporary workers, underemployed, or unemployed. The inhabitants of Villa IAPI suffer the effects of many adverse socio-economic(More)
The aim of the present study was to assess the catch-up growth in the postcranial skeleton of intrauterine growth retarded (IUGR) rats. Male and female Wistar rats were assigned to one of the following groups: controls, sham-operated, IUGR. The IUGR was produced by uterine vessels bending (day 14th of pregnancy). Trunk, pelvis, femur and humerus were(More)
We studied the adult height (AH) outcome, and factors likely to influence it, in Turner Syndrome (TS) girls treated with growth hormone (GH). A total of 25 TS girls treated with GH were compared with 10 TS girls not treated with GH. The percentage of girls who achieved normal third percentile was determined. Projected AH (PAH) was calculated according to(More)
AIM To analyze the secular changes in body size and composition of two cohorts of children from La Plata City, Argentina, with a 35-year follow-up. subjects and methods: Cohort 1 (C1) was measured in 1969-1970 and included 1772 children (889 boys, 883 girls), and Cohort 2 (C2), measured in 2004-2005, included 1059 children (542 boys, 517 girls). Both(More)
In the II Latin American Symposium on Pediatric Endocrinology (Buenos Aires, 1986) a short-cut method -the 5B technique- for radiographic BA estimation was discussed. Five hand-wrist bones were chosen:the epiphyseal proximal phalange of the fifth finger (5), the great bone (G), the trapezius bone (T), the distal epiphysis of the radius (R), and the distal(More)
PURPOSE The aim of the study was to analyze the effect of postnatal nutritional rehabilitation on the craniofacial growth in rats with intrauterine growth retardation (IUGR). MATERIALS AND METHODS Wistar rats were assigned to one of the following groups: control, Sham-operated, and IUGR. The IUGR was produced by uterine vessels bending (day 14 of(More)
This paper addresses the effect of a reduction of uterine blood flow (RUB) on postcranial bone growth in rats. The objectives were: (1) to discover and characterize the changes evoked by growth retardation through a reduction in placental blood flow, (2) to see if the resulting growth retardation is different in each bone, and (3) to analyze any(More)
The objective of this study was to analyse the effects of intrauterine growth retardation (IUGR) and growth hormone (Gh) therapy on skeletal maturation in growth retarded rats. One-hundred and thirty-five rats constituted the groups: Control (C), Sham-operated (SH), IUGR and IUGR+Gh: injected with Genotropin 3.0 mg/kg/day) from 21 to 60 days of age. SH was(More)
