Objectives: Prader-Willi syndrome (PWS) is a complex multisystem disorder due to loss of expression of paternally derived genes in the PWS critical region on chromosome 15q11-q13. The majority of the cases are due to the deletion of this region (del15), while 20–30% are caused by a maternal uniparental disomy of chromosome 15 (UPD15). The clinical picture is characterized by neonatal hypotonia and feeding difficulties in early infancy, early development of hyperphagia wit...

Aim: Few data are currently available on the reliability of the different anthropometric, instrumental and biochemical indexes in recognizing the presence of the metabolic syndrome (MetS) in severe childhood obesity. The objective of our study was to find out a simple and accurate index to use in deciding whether to initiate a search for MetS in this at-risk population.Patients and Methods: A retrospective study based on...

Objective: There is no agreement about which index of adiposity and/or body composition is the most accurate in identifying the metabolic syndrome (METS). The aim of our study was to compare the accuracy of the different indexes in order to recognize the most reliable.Study Design: We evaluated 1332 obese children and adolescents (778 females and 554 males), aged 14.4 ± 1.8 yrs., Body Mass Index (BMI) standard devia...

Background: Adult subjects with Prader-Willi Syndrome (PWS) have low Bone Mineral Density (BMD) and are at risk of osteoporosis. Several observations suggest that peak bone mass is usually achieved by late adolescence, in the presence of adequate gonadal hormone concentrations. Consequently, the altered bone characteristics of PWS patients may be related to inadequate sex steroid levels during pubertal development.Aim: To investigate BMD in PWS females d...

Introduction: Previous reports support the hypothesis of an age dependent derangement of the hypothalamus–pituitary axis occurring in PWS subjects. In this context, transition years represent an important phase of growth process when somatic development reaches its completion. In the general population, GH deficiency (GHD) during the transition phase is associated with deterioration of body composition, metabolic alterations and reduced bone mineral density. PWS subjects ...

Introduction: Previous studies showed that non-obese children and adults with Prader-Willi syndrome (PWS) have a low frequency of metabolic syndrome (MetS), while obese ones have a frequency similar to that of non-PWS obese. It is known that individuals born small for gestational age (SGA) have a greater predisposition to the development of MetS. Recent neonatal percentiles of subjects with PWS (Salvatoni et al, Am J Med Genet Part A, 2019) documented...

Background: Mild TSH elevations are frequently observed in obese patients, in the absence of any detectable thyroid disease.Aims and objective: To evaluate possible causes for the raised TSH levels and to verify possible biochemical and clinical consequences of this condition.Methods: We evaluated 779 (325 males/454 females) obese children, chronological age 14.38±2.56 (range 5.25 to 18.50), height SDS 0.27±1.04 (range &#...

Introduction: Laron Syndrome (LS) or primary growth hormone (GH) insensitivity is an autosomal recessive disorder due to variants in the GH-receptor (GHR) gene or to post-receptor defects. LS prevalence is estimated 1-9/1000000. We report a case of LS with a missense variant in the GHR gene not previously described.Case: female, Turkish, was referred to our clinic for short stature. Born at term, birth ...

Introduction: McCune Albright Syndrome (MAS) is a rare disorder caused by somatic activating mutations of the GNAS gene, characterized by monostotic/polyostotic fibrous dysplasia, café au lait skin pigmentation and hyperfunctioning endocrinopathies. We report a case of MAS presenting with mild phenotypic characteristics and central precocious puberty (CPP).Case: Indian female was referred to our clinic fo...

Introduction: The IGSF1 gene deficiency syndrome (IDS) is an X-linked disorder involving hormonal disfunctions. We report a case of Central Hypothyroidism (CH) due to a Xq26.1q26.2 microdeletion including the IGSF1 gene.Case: this boy was referred to our clinic for thyroid dysfunction. He was born at term by caesarean section due to maternal uterine myoma. Pregnancy was normal, parents were non consangu...
