[Fasting glucose versus oral glucose tolerance test for detection of glucose intolerance in obese children].

Background: Recently, the cut-off point for normal fasting glucose (FG) level, was decreased to 100 mg/dl.

Aim: To determine the frequency of abnormal carbohydrate abnormalities in children with obesity and evaluate if the fasting glucose level is a useful tool for the screening of glucose intolerance (GI).

Patients And Methods: Children and adolescents, referred for evaluation of obesity were evaluated with an oral glucose tolerance test (OGTT) and FG.

[IGF-I sensitivity in small for gestational age children].

Background: The lack of catch up growth (CUG) in small for gestational age (SGA) children may be related to a reduced sensitivity to insulin growth factor 1 (IGF-I).

Aim: To assess the sensitivity to IGF-I in small for gestational age children, measuring basal and post IGF-I nocturnal profile of growth hormone (GH).

Patients And Methods: We studied 34 prepubertal SGA children aged 4 to 11 years.
