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...

Anorexia nervosa (AN) manifests in the restriction of energy intake relative to energy output. Atypical AN includes those who meet the criteria for AN but are not underweight. Hypothalamic amenorrhea can be a presenting symptom in AN, and the return of menses is part of recovery. It can take more than a year for menses to return after weight restoration and nutritional rehabilitation. Hypercortisolemia is common in AN, but usually does not cause cushingoid symptoms We describe...

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: 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...

Introduction: Primary ovarian Insufficiency (POI) occurring in youth is a devastating condition. POI is characterized by at least 4 months of disordered menses in association with menopausal follicle stimulating hormone (FSH) levels. The most common causes of POI in adolescence are iatrogenic and chromosomal abnormalities. Data are scarce regarding the incidence of POI in adolescents.Objectives: We aimed to estimate the incidence and the distribution of ...
