Background: Genome-wide association studies have identified more than 60 SNPs associated with BMI. Additional genetic variants, such as copy number variations (CNV), have also been implicated in the pathogenesis of obesity. Recently, the highly polymorphic CNV in the salivary amylase (AMY1) gene has been associated with obesity risk in adults.Objective and hypothesis: To assess the potential association between AMY1 copy number and BMI ...

Introduction: About 25% of children and adolescents with Type 1 Diabetes (T1D) have one or more associated autoimmune conditions. Although Graves' disease (GD) rarely occurs, considering the potential severity of manifestations, an early diagnosis and appropriate treatment are essential. The first line treatment is methimazole, whose use is not free from side effects; therefore, it is important to start with the most appropriate dosage.<p class="abste...

Background: NGLY1 encodes the enzyme N-glycanase that catalyzes protein deglycosylation in the process of protein degradation. Loss of function mutations in NGLY1 lead to a disorder of N-linked deglycosylation which is a rare multisystemic disease. The typical phenotype includes intellectual disability, liver dysfunction, muscular hypotonia, involuntary movements and decreased or absent tear production. Adrenal insufficiency has been previously reported in onl...

Background: Type 1 diabetes is one of the most common chronic diseases in childhood. Parents of children with type 1 diabetes are significantly involved in the treatment, rendering them vulnerable to parental stress. Psychological difficulties experienced by the parents may have adverse effects on disease management and the child's psychological and somatic health.Objectives: To assess parental stress and factors in...

Purpose: Understanding the normal range of laboratory values as pertained to different age groups and males or females is paramount in health care delivery. We aimed to assess the distribution of glucose levels by age and sex in the general population of children using a large-scale population-based cohort.Methods: A retrospective study with real-world de-identified data from a large, state mandated health fund in Israel...

Background: Endogenous Neonatal Cushing's syndrome (CS) is a rare condition with around 100 cases reported worldwide. Pneumocystis Jiroveci pneumonitis (PJP) is a well described, albeit rare, complication of exogenous CS (i.e. CS resulting from external glucocorticoids). The pneumonitis usually occurs following reduction of glucocorticoid dosage and is therefore thought to be triggered by an inappropriate immune reaction evident after glucocorticoids withd...

Background: Disorders of the calcium sensing receptor (CaSR) cause hyper- and hypo- calcemia, depending on the location and type of mutation. Familial hypocalciuric hypercalcemia is a benign disorder in which calcium levels are slightly elevated in the presence of slightly elevated parathyroid hormone (PTH). Neonatal severe hyperparathyroidism (NSHPT) is a rare life-threatening disorder in which there are high levels of calcium accompanied by high levels of pa...

Background: Medical nutrition therapy is one of the cornerstones of the treatment of type 1 diabetes. Nutrition is affected by many factors including ethnicity, socioeconomic background, and culture.Objectives: To evaluate the nutritional status in a cohort of children with type 1 diabetes from different ethnic backgrounds and to seek differences among the groups. In addition determine the effect of nutrition on metaboli...

Background: Phosphoglucomutase 1 (PGM-1) deficiency is a congenital disorder of glycosylation caused by an impairment of glucose-1-phosphate and glucose-6-phosphate interconversion.The clinical phenotype of PGM1 deficiency is variable and includes several endocrine manifestations such as recurrent hypoglycemia and short stature, which may be associated with the decreased levels of growth hormone (GH), insulin like growth factor-1 (IGF1) ...

Background: Mutations in the gene HSD17B3 encoding the 17-beta hydroxysteroid dehydrogenase 3 enzyme cause testosterone insufficiency leading to XY DSD. In this study the clinical characteristics and molecular etiology of 3 new severe XY DSD cases from consanguineous families are elucidated.Clinical report: Three female patients (2 sisters and a single unrelated female) presented at ages 0.1, 8 and 0.7 years with ambiguo...
