Background: Diabetic ketoacidosis (DKA) as the first presentation of type 1 diabetes mellitus (T1DM) is a serious complication that is preventable.

Objectives: To identify risk factors for DKA at presentation of T1DM to delineate high-risk Israeli populations that could benefit from preventative measures.

Methods: Data for this multicenter retrospective study were collected from the medical files of three pediatric diabetes centers representing three districts in Israel. Inclusion criteria were diagnosis of T1DM, age at diagnosis ≤ 17 years, permanent residency in Israel, and documentation of the presence or absence of DKA at presentation.

Results: The study population included 607 patients of whom 438 met the inclusion criteria. The mean age at diagnosis was 9.1 ± 4.5 years. DKA was present at diagnosis in 156/438 patients (35.6%). The incidence of DKA was different among the three diabetes centers (P = 0.04). The DKA group was significantly younger than the non-DKA group (8.4 ± 4.5 vs. 9.5 ± 4.4, respectively, P = 0.008). DKA was significantly associated with maternal origin (Ashkenazi Jewish origin [lower] vs. non-Ashkenazi, P = 0.04) and with paternal education level (academic [lower] vs. non-academic education, P = 0.04). Stepwise logistic regression showed that maternal Ashkenazi Jewish origin has a protective effect on DKA (odds ratio [OR] 0.4, 95% confidence interval [95%CI] 0.21–0.74, P = 0.004) and that younger age is an independent risk factor (OR 1.06, 95%CI 1.01–1.1, P = 0.02).

Conclusions: A diabetes educational program targeting high-risk population groups may reduce the prevalence of DKA nationwide.

Background: Bone maturation is currently assessed by subjective and automated radiography. 

Objectives: To evaluate the concordance and reproducibility of a quantitative ultrasound (QUS) based device versus X-ray based methods.

Methods: The study population comprised 150 children, 76 males, 4–17 years of age. X-ray scans were evaluated according to wrist, carpal and phalanx areas for bone age. QUS was performed by the the BAUS™ device (SonicBone, Rishon Lezion, Israel), using speed-of-sound (SOS) and distance attenuation factor (ATN) in similar areas. Data from 100 subjects were used to establish the device conversion equation, and 50 measurements were assigned to assess inter-modality agreement. 

Results: BAUS showed high repeatability performance, 0.73% relative standard deviation for SOS and 3.5% for ATN. R2 for the conversion equation, including gender, SOS, and ATN, was 0.80 for all methods (P < 0.001). There was no significant bias in bone age assessments.

Conclusions: Bone age assessment by SonicBone is comparable to the assessment by X-ray based methods. 

 

Micronutrient deficiencies have reoccupied the center stage of public health policy with the realization that folic acid deficiency results in neural tube defects and possibly other birth defects as well as ischemic heart disease. These, in turn, have raised an older debate on food fortification policy for the elimination of iodine, iron and vitamin D deficiencies. Data from the First Israeli National Health and Nutrition Survey (MABAT 2000) provided an impetus to develop an active national nutrition policy aimed to improve the nutritional status of iodine, iron, vitamins A and D and B-vitamins, including folate. In this paper we examine some of the MND[1] issues in Israel and their implications for public health, and suggest options for the formulation of policy.
