Background/aims: Primary IGF1 deficiency (IGFD)’ is defined by low levels of IGF1 without a concomitant impairment in GH secretion in the absence of secondary cause. The aims of this study were to evaluate the prevalence of non-GH deficient IGFD in prepubertal children with isolated short stature (SS) and to describe their response to GH therapy.Methods: This retrospective study included all children with isolated S...

In ISS is a condition with a height is >2SD below the corresponding mean for age, sex, and population. Thyroid abnormalities reported during GH therapy in GH deficient (GHD) children but not well studied in ISS children on GH therapy.Aim: To investigate effects of GH therapy on TF in a group of euthyroid children with ISS in comparison with ISS group not receiving GH therapy and GHD group on GH therapy.Material...

ISS is a condition in which the height is more than 2 SD below the corresponding mean height for age, sex and population, in whom no identifiable disorder is present. Some ISS patients may have varying degrees of IGF-1 deficiency. Recombinant GH treatment has been used by some authors with variable results. Theoretically, low IGF-I level at presentation may affect their response to GH therapy. The question is: do children with ISS and low IGF-I respond differently to GH therap...

Introduction: Mid-parental height (MPH) is a useful tool in the prediction of final adult height in normal children as well as those on growth hormone (GH) therapy. Aim of the study to evaluate the growth response to GH therapy in GHD children in relation to their MPH.Methods: This retrospective study included 22 short prepubertal children with GHD (peak GH<10 μg/l). They were followed in the Endocrine clinic be...

Introduction: Children with idiopathic short stature have linear growth impairment despite normal or even high levels of GH. In some of these children IGFI level is low (NGH + Low IGFI (IGFSDS<-1.5). It was observed that some children with GHD (Peak GH < 7 ng/dl after provocation) have normal IGFI levels (GHD +Normal IGFI). The linear growth of these two groups at presentation and their response to GH therapy was not studied well.<p class="abstext"...

Background: Debate still exists about the safety of long-term use of prednisone (PD) versus hydrocortisone (HC) for treating children with CAH. Relatively slight supraphysiologic levels may be enough to blunt growth velocity, increase weight gain.Objectives of the study: We evaluated the anthropometric and biochemical effects of long-term PD versus HC treatment in children with CAH-21OHD.<p class="ab...

Introduction: 5α-reductase type 2 deficiency (5α--RD) and 17β-HSD type 3 deficiency (17β-HSDD) are rare differences/disorders of sex development (DSD) in which impairment of steroidogenic enzymes causes undervirilisation in patients with a 46,XY genotype. We aim to enlarge the limited knowledge on long-term gonadal function and gonadal pathology in these conditions.Methods: Data on phenotype, laborato...

Background: Hypophosphatasia (HPP) is an inherited multisystem disorder predominantly affecting the mineralization of bones and teeth. HPP is caused by pathogenic variants in ALPL, which encodes tissue non-specific alkaline phosphatase. A major challenge in diagnosing HPP is interpreting variants in ALPL classified as variants of uncertain significance (VUS) according to ACMG/AMP criteria, creating uncertainty in patients and treating physicians resulting in d...

Background: Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation (ROHHADNET) is a rare disorder which presents in early childhood.Case presentation: Four years old girl was referred to endocrinology unit with a history of excessive weight gain. Parents noticed a rapid weight gain from 3 years of age with increase food seeking behaviour and daytime somnolence. Her weight was >95th centile and her height was o...

Background: Mosaic Turner syndrome (TSM) commonly occurs in the form of 45,X/46,XX and 45,X/46,Xiq, although mosaicism including the presence of a Y chromosome has been well documented. It is associated with increased risk of gonadoblastoma (GB).Objective and hypotheses: To date, there are only six reported cases of TSM with a trisomy 18 karyotype, and only two of these were phenotypically female with 45,X, 47,XY+18 karyotype.Metho...
