Background: OTX2 is expressed in the human brain and plays a key role in the eye development. OTX2 mutations are reported in patients with ano/microphtalmia, optic nerve or optic chiasm hypoplasia, ocular coloboma and retinal dystrophies, associated in some cases with brain or pituitary abnormalities.Objective and hypotheses: Most of OTX2 mutations are nonsense or frameshift, more rarely missense mutations occur.Method: We...

Objective and hypotheses: We studied the prevalence of deficiency in the short stature homeobox containing gene (SHOX) in short-statured children and analysed clinical and radiological signs.Method: A total of 162 children aged 1–17 years (53% females, 67% prepubertal, median age 6.6 years, median height SDS −1.7) presenting with short stature between 2008 and 2014, were analysed for SHOX mutations by direct sequencing and multiplex ligation p...

Short stature is a common clinical presentation in children. New genetics approache such as “Next Generation Sequencing” have recently reported many monogenic defects in genes related to the growth plate cartilage and in GH-IGF-1 axis. The purpose of this study was to analyze a cohort of 64 patients (31 females and 33 males) affected by ISS. The patiens have been subjected to genetic investigations by performing an NGS panel of genes involved in growth, the evaluat...

Introduction: Short stature is one of the main reasons leading a patient to the attention of the Pediatric Endocrinologist. It is important to know the possible causes of short stature, even the rarest genetic mutations associated with short stature. Although the diagnosis of short stature is primarily the result of physical examination with anthropometric measurements, biochemical and radiological data, genetical tests currently play an important role.<p ...

Pediatric obesity is constantly increasing and exposes to serious cardiovascular and metabolic risks. The first treatment against obesity is lifestyle change. Actually, any intervention seems to be effective on the evolution of this condition, especially in the long term. For this reason, the interest in non-pharmaceutical compounds is growing. Several studies mentioned the use of zinc and inositol as compounds acting on weight loss and insulin resistance. The aim of this stud...

V.C. was referred to our Centre for short stature. The mid-parental target height was 153 cm (-1,6 SDS). Her mother had one spontaneous abortion and displayed mild short stature (151,5 cm). Her father had Arnold Chiari syndrome type 1 and was 165,9 cm tall. V.C. was delivered at term after in-vitro-fertilization pregnancy with intrauterine growth retardation (IUGR) from gestational week 21. Birth weight was 2160 g (SGA, SDS -3,17); length was 45 cm (SDS -2,92); head circumfere...

We report rhGH-treatment results in a 14-yrs-old SGA patient with spondylo-epi-metaphyseal chondrodysplasia. The patient carries a rare de novo eterozygous variant of COLA1 (c.1510G>A, P.Gly 504Ser) associated with a rare AD spondylo-epiphyseal dysplasia. Born at term after olygohidramnios-complicated pregnancy, SGA for weight and lenght, the patient has showed a post-natal reducing growth with regular cognitive development. At the age of two height was -4 SDS, with parenta...

Short stature is a frequent disorder in the pediatric population caused by multiple possible reasons. One of them it can be the mutation of the ACAN gene, with an autosomal dominant transmission, which also correlates with accelerated bone maturation and early osteoarthritis up to bone dysplasia. A 10.8-year-old patient came to our observation for poor statural growth (125.8 cm, -2.6 SDS) with a parental target of 150.4 cm +/- 8 cm (-2 SDS), on Triptorelin braking therapy, sin...

Background: Human GH is a heterogeneous protein hormone consisting of several isoforms, the most abundant being 22 kDa- and 20 kDa-GH. The availability of analytical methods to measure these GH isoforms might represent a valuable diagnostic tool to investigate GH secretion in short stature.Objective and hypotheses: Aim of the present study was to measure circulating levels of 22 kDa- and 20 kDa-GH in children with different diagnosis of short stature suc...

Introduction: Peripubertal children with delayed puberty frequently display a poor growth rate prompting endocrine work-up. Whether priming with sex steroids should routinely be performed in these patients to improve specificity of growth hormone stimulation tests (GHST) is unclear. Treatment with sex steroids in constitutional delay of growth and puberty (CDGP) is also debated.Patients and Methods: This multicenter retr...
