Lower Basal Insulin Dose – Better Control in Type 1 Diabetes

Strich David , Balgor Lucy , Gillis David

Introduction: There is no valid evidenced-based recommendation for the optimum basal insulin dose in type-1 diabetes mellitus when supplied either by continuous subcutaneous insulin infusion (CSII) or multiple daily injections (MDI). We studied this previously by evaluating the dose associated with successful fasting. Another way of looking at this is by evaluating the association between basal insulin dose and HbA1c. To this end we performed a retrospective study of 89 childr...

TSH: Different Normalization Methods, Very Different Normal Upper Limits

Strich David , Karavani Gilad , Gillis David

Background: Distribution of TSH levels is not normal. This is due to physiological changes that cause temporary increases in TSH during physiological events. Several methods are used to normalize the distribution when defining normal limits.Objective and hypotheses: To compare the normal limits defined by three normalization methods vs non-normalized distribution based on a large cohort with no known thyroidal illness.Method: Data ...

Optimal 25-OH-Vitamin D level in children derived from metabolic parameters

Gillis David , Hefter Ari , Edri Edri Shalom , Strich David

Context: Optimal levels of 25-OH-Vitamin D (25OHD) for children are unknown. Prevalent population levels of 25OHD are likely to be sub-optimal since sun exposure is reduced in modern living.Objective: To deduce recommended levels of 25OHD by testing, in children, the level at which 25OHD optimally effects calcium, phosphate and parathyroid hormone levels in a population-based data.Design:</...

Vitamin D - What is the Optimal Level in the Pediatric Population

Gillis David , Hefter Ari , Edri Shalom , Strich David ,

Introduction: The optimal level of 25-OH-Vitamin D in children is not clear since most studies have been performed on adults. Creating normal levels is problematic since the recommended level of vitamin D is based on the effect of vitamin D on other parameters and not upon its level in the population.Methods: This is a "big-data" study in which we analyzed Vitamin D tests from 49,935 children sampled in Clalit He...

Case Report: Massive Obesity secondary to a Homozygous MC4R mutation in a 3-year-old Boy

Gillis David , Hefter Ari , Edri Edri Shalom , Strich David

We present a 3-year-old boy with massive obesity and hyperphagia. His appetite symptoms were evident from age 3 months, and his parents report he has an insatiable appetite, and seeks food constantly. At presentation to our clinic, his BMI was 37.21 Kg/m² [+ 6.87 SDS]. Sleep apnoea is suspected, for which he is undergoing evaluation. Parents are second cousins. Both parents are moderately obese, but his siblings are normal weight for age. The mother did not have a history...

Pneumocystis Jiroveci Pneumonitis Complicating Neonatal Cushing's Syndrome - the Therapeutic Dilemma

Auerbach Adi , Gillis David , Megged Orly , Shahroor Sarit , Avnon-Ziv Carmit , Hirsch Harry , Levy-Khademi Floris

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...

Severe Neonatal Hyperparathyroidism Due to a Novel Homozygous Mutation of the Calcium-Sensing Receptor (CaSR)

Homozygous loss-of-function mutations of the calcium-sensing receptor gene (CaSR) are associated with neonatal severe hyperparathyroidism (NSHPT), a life-threatening condition with a challenging treatment approach.We report a 7-day-old-female infant who was admitted to our Pediatric Department due to poor sucking. On examination she was lethargic and hypotonic. Laboratory evaluation revealed extreme hypercalcemia of 23.54 mg/dL (N: 7.6–10.4...

Developing a Collaborative Research Network to Accelerate the Understanding and Treatment of the Rare Disease Congenital Hyperinsulinism

Background: Congenital Hyperinsulinism International (CHI) is an international non-profit organization focused on improving the lives of patients and families living with hyperinsulinism (HI). Despite many advances in the care of patients with HI, long term neurologic outcomes have not significantly improved, highlighting the need for CHI’s goals for robust and rapidly translatable research. We describe the development of a collaborative research network...
