Growth hormone responses during arginine and clonidine stimulation test: Correlations with patients' auxological and metabolic parameters in a single centre study.

Background: Children with auxological parameters defining a 'short stature' is routinely subjected to various blood tests and, if necessary, to growth hormone stimulation test (GHST) for differentiating GH deficiency (GHD) and other causes of stunted growth.

Aim: This retrospective monocentric study aimed to evaluate any correlations between GH peaks during GHST in children assessed for short stature and their auxological/metabolic parameters, highlighting differences between GHD and idiopathic short stature.

Patients And Methods: We reviewed the medical records of 74 children with short stature (height lower than the third percentile according to standardized growth curves for the Italian population) managed at the Pediatric Day Hospital of our Department of Life Sciences and Public Health in Università Cattolica Sacro Cuore, Rome, who performed at least two GHSTs, using arginine and clonidine as stimulants, for assessment of GH secretion.

Body mass index in type 2 spinal muscular atrophy: a longitudinal study.

Unlabelled: The aim of this retrospective study was to review body mass index (BMI) in a large cohort of Italian pediatric type 2 spinal muscular atrophy (SMA) patients, aged between 0 and 20 years and to establish possible differences in relation to a number of variables such as ventilation, motor function, and survival motor neuron 2 gene copies. Cross-sectional data were collected from 102 patients for a total of 344 visits. Standard growth charts for height and weight were used as reference, with age adjusted BMI calculated using the Center for Disease and Prevention Children's BMI Tool.
