- The spontaneous growth process in Turner's syndrome is characterized by a progressive decline in height velocity during childhood and no pubertal growth spurt. Therefore, therapy aimed at improving height during childhood as well as increasing final height is desirable for most girls with Turner's syndrome. Forty-five girls with Turner's syndrome, 9-16 yr of age (mean age, 12.2 yr), were allocated to three study groups. Group 1 (n = 13) was initially treated with oxandrolone alone; after 1 yr of treatment, GH without (group 1a; n = 6) or with (group 1b; n = 7) ethinyl estradiol was added. Group 2 (n = 17) was treated with GH plus oxandrolone. Group 3 (n = 15) was treated with GH, oxandrolone, and ethinyl estradiol. The dosage were: GH, 0.1 IU/kg.day; oxandrolone, 0.05 mg/kg.day; and ethinyl estradiol, 100 ng/kg.day. A height of 150 cm or more was achieved in 61%, 75%, and 60% of the girls in groups 1, 2, and 3, respectively. The most impressive increase in height was seen in group 2. In this group the mean final height was 154.2 cm (SD = 6.6), which is equivalent to a mean net gain of 8.5 cm (SD = 4.6) over the projected final height. In group 3, in which ethinyl estradiol was included from the start of therapy, the initially good height velocity decelerated after 1-2 yr of treatment. Their mean final height was 151.1 (SD = 4.6) cm, equivalent to a mean net gain of 3.0 cm (SD = 3.8). A similar growth-decelerating effect of ethinyl estradiol was seen in group 1b. We conclude that in girls with Turner's syndrome who are older than 9 yr of age, treatment with GH in combination with oxandrolone results in significant growth acceleration, imitating that in normal puberty, leading to a more favorable height during childhood. This mode of treatment also results in a significantly increased final height, permitting a great number of the girls to attain a final height of more than 150 cm. However, early addition of estrogen decelerates the height velocity and reduces the gain in height.

- This study was undertaken to investigate the prevalence of coeliac disease in children and adolescents with Turner syndrome. Eighty-seven children and adolescents with Turner syndrome were screened for IgA- antiendomysium antibodies (EMA) and IgA-antigliadin antibodies (AGA), 5% (4/87) being found to be EMA-positive, and 15% (13/87) to have AGA levels above normal. Of the 10 patients who were either AGA- or EMA-positive and further investigated with intestinal biopsy, four manifested villous atrophy (i.e. all three of the EMA-positive patients, but only one of the seven AGA- positive patients). The results suggest EMA-positivity to be a good immunological marker for use in screening for coeliac disease, and such screening to be justified in patients with Turner syndrome.

- Plasticity in developmental programming has evolved in order to provide the best chances of survival and reproductive success to the organism under changing environments. Environmental conditions that are experienced in early life can profoundly influence human biology and long-term health. Developmental origins of health and disease and life-history transitions are purported to use placental, nutritional, and endocrine cues for setting long-term biological, mental, and behavioral strategies in response to local ecological and/or social conditions. The window of developmental plasticity extends from preconception to early childhood and involves epigenetic responses to environmental changes, which exert their effects during life-history phase transitions. These epigenetic responses influence development, cell- and tissue-specific gene expression, and sexual dimorphism, and, in exceptional cases, could be transmitted transgenerationally. Translational epigenetic research in child health is a reiterative process that ranges from research in the basic sciences, preclinical research, and pediatric clinical research. Identifying the epigenetic consequences of fetal programming creates potential applications in clinical practice: the development of epigenetic biomarkers for early diagnosis of disease, the ability to identify susceptible individuals at risk for adult diseases, and the development of novel preventive and curative measures that are based on diet and/or novel epigenetic drugs.

- OBJECTIVE: To test the hypothesise that post-term birth (>42 weeks gestation) adversely affects longitudinal growth and weight gain throughout childhood. STUDY DESIGN: A total of 525 children (including 17 boys and 20 girls born post-term) were followed from birth to age 16 years. Weight and height were recorded prospectively throughout childhood, and respective velocities from birth to end of puberty were calculated using a mathematical model. RESULTS: At birth, post-term girls were slimmer than term girls (ponderal index, 27.7±2.6 kg/m(3) vs 26.3±2.8 kg/m(3); P<.05). At age 16 years, post-term boys were 11.8 kg heavier than term subjects (body mass index [BMI], 25.4±5.5 kg/m(2) vs 21.7±3.1 kg/m(2); P<.01). The rate of obesity was 29% in post-term boys and 7% in term boys (P<.01), and the combined rate of overweight and obesity was 47% in post-term boys and 13% in term boys (P<.01). Weight velocity, but not height velocity, was higher in post-term boys at age 1.5-7 years (P<.05) and again at age 11.5-16 years (P<.05). BMI was higher in post-term boys at age 3 years, with the difference increasing thereafter. BMI and growth were similar in post-term and term girls. CONCLUSION: In this post-term birth cohort, boys, but not girls, demonstrated accelerated weight gain during childhood, leading to greater risk of obesity in adolescence.

Leptin levels are strongly correlated with those of GH-binding protein in prepubertal children.

- There was a highly significant correlation between serum levels of leptin and those of GHBP, except in children with GHD. The possibility that leptin could mediate the effects of body fat mass on GH sensitivity, therefore, merits further investigation.

- Optimal nutrient intake ensuring better neurodevelopment for very low birth weight (VLBW) infants remains unknown. The aim of this study was to assess the relationship between early (first 28 days) nutritional intake, first year growth, and neurodevelopment. In total, 120 VLBW infants were included into the study. A group of 95 infants completed follow-up to 12 months of corrected gestational age (CGA). Nutrient intake was assessed, and weight, length, and head circumference (HC) were measured weekly until discharge and at 3, 6, 9, and 12 months of CGA. Neurodevelopment was assessed at 12 months of CGA. Two groups-extremely preterm (EP) and very/moderately preterm (VP)-were compared. Growth before discharge was slower in the EP group than the VP group. At 12 months, there was no difference in anthropometric characteristics or neurodevelopmental scores between the groups. Higher carbohydrate intake during the first 28 days was the single significant predictor for better cognitive scores only in the EP group (beta(s) = 0.60, p = 0.017). Other nutrients and growth before discharge were not significant for cognitive and motor scores in either group in multivariable models, whereas post-discharge HC growth was associated with both cognitive and motor scores in the VP group. Monitoring intake of all nutrients and both pre-discharge and post-discharge growth is essential for gaining knowledge about individualized nutrition for optimal neurodevelopment.
