OBJECTIVE Children and adolescents with type 1 (insulin-dependent) diabetes mellitus (T1DM) show several impairment of bone metabolism and structure, resulting in a higher risk of decreased bone mass and its related complications later in life. Alterations of the nuclear factor-kappaB ligand (RANKL)/osteoprotegerin (OPG) system have been implicated in(More)
Time patterns in nocturnal concentrations of circulating melatonin of children are quantified in 8 girls and 8 boys, 8.7-16.8 yr of age, classified by Tanner pubertal stage. Between 1900 and 0700 h, each provided blood samples at 30-min intervals for melatonin RIA. Associations with gender, body mass index, and chronological and pubertal age determined by(More)
INTRODUCTION Adults and children affected by human immunodeficiency virus type-1 (HIV-1) infection show bone demineralization. Little is known about skeletal status using a quantitative high-frequency ultrasound (QUS) technique in these patients. OBJECTIVE To evaluate the bone quality and assess the role of the IGF system in the bone metabolism and(More)
We examined 22 girls and 11 boys with idiopathic precocious puberty (IPP) treated with a GnRH analogue for a period of about 4 y. The purpose of our study was to evaluate possible differences between the two sexes in bone growth and skeletal maturation during treatment and in the achievement of final height, and also to study the relative contribution of(More)
BACKGROUND The diagnosis of growth hormone deficiency (GHD) is based on clinical and auxological characteristics combined with the results of growth hormone provocation tests. AIM To evaluate the utility of IGF-I and IGF-BP3 serum levels in the diagnosis of GHD among children of short stature. SUBJECTS/METHODS We recruited 207 short pre-pubertal(More)
A multi-center four-hourly sampling of many tissues for 7 days (00:00 on April 5-20:00 to April 11, 2004), on rats standardized for 1 month in two rooms on antiphasic lighting regimens happened to start on the day after the second extremum of a moderate double magnetic storm gauged by the planetary geomagnetic Kp index (which at each extremum reached 6.3(More)
The trichorhinophalangeal syndromes (TRPSs) are syndromes due to haploinsufficiency of genes in the chromosome 8q24.12 region. Type I TRPS is characterized by typical facial features including sparse, brittle and fine hair, bulbous nose, and a long philtrum, as well as skeletal abnormalities. Growth retardation is a feature frequently found in these(More)
OBJECTIVE To evaluate the prevalence of abnormalities of thyroid function and morphology in a cohort of patients with Williams syndrome (WS). METHODS Serum concentrations of free-T3, free-T4, TSH, thyroperoxidase antibodies (TPOA) and thyroglobulin antibodies (TgA), as well as ultrasonographic data, of 20 patients with WS (12 females and eight males),(More)
Through a review of 83 cases reported in literature, including our experience of two successful right laparoscopic adrenalectomies performed in a 3-year-old girl for androgen-secreting adenoma and in a 9-year-old male for pheochromocitoma, we have anaIyzed the indications, the techniques and the results of laparoscopic or retroperitoneoscopic adrenalectomy(More)
OBJECTIVES Changes in magnetic field are associated with a decrease in nocturnal urinary melatonin excretion. Television screens emit low and very low frequency electromagnetic waves (radiofrequencies and light) and exposure to them may be associated with a decrease in 24-hour melatonin in children's urine. Design and setting. An observational study in(More)
