An excess of left-handers among males has been attributed to early androgen exposure. This theory was supported by our observation that girls with congenital adrenal hyperplasia (CAH) are more left-biased than their normal sisters. Male CAH patients, with prenatal androgen exposure similar to that of unaffected brothers, had typical male-handedness patterns.
Duodenal biopsy and tests for antigliadin antibodies were done in 108 children with short stature unassociated with gastrointestinal symptoms. Other investigations for causes of growth failure were also carried out. In 88 patients, the cause of short stature could not be determined (group I). In 9 patients (8.3%) biopsy showed total villous atrophy,… (More)
Forty-nine children with short stature (age range, 4.1-15.9 yr) were examined. Twenty-four (group 1) were submitted twice to an arginine and a sleep test (12-h overnight GH profile). Twenty-five patients (group 2) were submitted twice to an arginine and L-dopa test. Coefficients of variation were calculated between both the results of pharmacological (peak… (More)
BACKGROUND The relationship between developmental obesity and emotional problems has been particularly studied by Bruch. According to this author, the main reason for early-onset obesity has to be found in the difficulty of some mothers to adequately distinguish between emotional manifestations and the child's real need for food. In this paper an experiment… (More)
Growth hormone (GH) release with pharmacological tests and sleep test, somatomedin C and auxological features were studied in 10 patients affected by Duchenne Muscular Dystrophy. GH release in these patients seems to be lower than normal; moreover some of them are of short stature without an evident relationship with GH deficit. The possible significance of… (More)
The effect of a one month treatment with flunarizine (5 mg/day) on pituitary responsiveness to gonadotrophin-releasing hormone (GnRH), thyrotrophin-releasing hormone (TRH) and arginine infusion was assessed in 17 adolescents (11 M, 6 F) treated with the drug to prevent migraine attacks. Basal prolactin concentrations as well as the prolactin response to TRH… (More)
A total lack of neuroendocrine and vegetative circadian rhythms was observed in a patient with a familial degeneration of the anterior and dorso-medial thalamic nuclei. Our findings support the role of the thalamus in regulating the periodicity of endocrine and vegetative functions.
