Purpose: To investigate the overall prevalence of vertebral fractures (VF) following childhood acute lymphoblastic leukemia (ALL) treatment and examine the association of VF with growth trajectory and insulin-like growth factorsMethods: Children (n = 172; 59.3 % male) diagnosed with ALL at age between 2 and 18 years were assessed for VF by screening the lateral thoracolumbar spine radiographs (Genant’s semi-quantitative met...

Background: The male Hypothalamic-Pituitary-Gonadal (HPG) axis undergoes a transient activity phase during the first months of life with surging serum concentrations of reproductive hormones. Theoretically, the hormonal surge could represent a passive postnatal feedback to the withdrawal from the high sex steroid levels in pregnancy. However, we believe that minipuberty rather represents an active, tightly genetically-regulated biological process. We therefore...

Background: Woodhouse-Sakati syndrome (WSS) is an extremely rare autosomal recessive multisystem disease. Ectodermal system findings, such as alopecia and changes in facial skin, endocrinological problems including hypogonadism, hypothyroidism, diabetes mellitus (DM), and decreased levels of insulin-like growth factor I (IGF-I), neurological disorders such as hearing loss and progressive extrapyramidal involvement are the components of this syndrome. The syndr...

Keywords: Sleep-Related Breathing Disorders, recombinant human Growth Hormone treatment, Prader–Willi syndrome, Toddlers.Background: Recombinant human growth hormone (rhGH) therapy is beneficial for children with Prader–Willi syndrome (PWS) in improving short stature and metabolism, but the effect of early rhGH treatment on respiratory and sleep parameters for the PWS children under three years old remains el...

We introduce the ReTRIACt Trial (NCT05579327) of tiratricol (Triac) for MCT8-deficiency, a rare X-linked disease resulting from disordered thyroid hormone transport and characterized by profound neurodevelopmental delay and features of chronic peripheral thyrotoxicosis. The ReTRIACt Trial aims to verify the effects of tiratricol observed in previous studies. It is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the effects of tiratricol discontinu...

Sitosterolemia is an autosomal recessive disorder affecting lipid metabolism which is characterized by decreased biliary excretion and increased absorption of plant sterols and cholesterol, leading to significantlyelevated serum levels of plant sterols. Approximately 80 homozygous or compound heterozygous variants in adenosine triphosphate-binding cassette subfamily G genes (ABCG5/ABCG8) genes have been described in patients with genetically confirmed sitosterolemia. Clinicall...

Introduction: Pubertal gynecomastia (PG), the benign enlargement of breast in adolescents, is a condition whose etiology has not been fully elucidated. Its peak incidence is at mid puberty and decreases thereafter. In many cases breast undergoes full or almost complete regression with advancement of pubertal development, but in others it persists into adulthood. There are still controversies on the precise hormonal imbalance that leads in some adolescents only...

Background: Severe Ovarian Dysgenesis (OD), a rare heterogeneous XX disorder of Sex Development (XX-DSD) presents clinically with primary amenorrhea, hypergonadotrophic hypogonadism and infertility. The genetic basis of OD remains unknown in about 70% of cases. To identify novel causes of OD, we study patients in which known genes have been excluded.Methods: Whole-exome-sequencing was performed on DNA extracted from peri...

Introduction: The production of ischemia-modified albumin (IMA) is associated with the production of reactive oxygen species modifying the metal-binding sites of albumin. IMA is considered a non-specific early biomarker in the evaluation of oxidative stress status. Cortisol is known to trigger anti-inflammatory actions through genomic and non-genomic pathways that eventually lead to decreased production of cytokines, chemokines, and inducible nitric oxide synt...

Background: Detection of type 1 diabetes (T1D) at the pre-clinical stage is possible by detecting islet autoantibodies (IA) years before the appearance of symptomatic diabetes. An efficient screening program based on these antibodies will identify children at risk of developing diabetes during childhood. The antibody detection Israeli research (ADIR) is a general population screening program in Israel searching for children with multiple IA who are at risk of ...
