IgA vasculitis, formerly known as Henoch–Schönlein purpura (HSP), is the most common systemic vasculitis in children. It is defined as palpable purpura in the absence of coagulopathy or thrombocytopenia and one or more of the following criteria: abdominal pain, arthritis or arthralgia, biopsy of affected tissue demonstrating predominant IgA deposition, and renal involvement with proteinuria and hematuria or red cell casts [1].

The attention of the world is focused on the coronavirus disease-2019 (COVID-19) pandemic. There is s general awareness that certain population groups are at greater risk. However, some other populations may be transparent and may not be receiving the attention they warrant. We focused on those with intellectual disability explaining why they are vulnerable during the current pandemic and require special attention

Background: Patients with type 1 diabetes (T1D) are exempt from conscript military service, but some volunteer for national service. 

Objectives: To evaluate the effect of national service (military or civil) on metabolic control and incidence of acute diabetes complications in young adults with T1D. 

Methods: Clinical and laboratory data of 145 T1D patients were retrieved from medical records. The cohort comprised 76 patients volunteering for national service and 69 non-volunteers. Outcome measures were HbA1c, body mass index-standard deviation scores (BMI-SDS), insulin dosage, and occurrence of severe hypoglycemia or diabetic ketoacidosis (DKA). 

Results: Metabolic control was similar in volunteers and non-volunteers: mean HbA1c at various time points was: 7.83 ± 1.52% vs. 8.07% ± 1.63 one year before enlistment age, 7.89 ± 1.36% vs. 7.93 ± 1.42% at enlistment age, 7.81 ± 1.28% vs. 8.00 ± 1.22% one year thereafter, 7.68 ± 0.88% vs. 7.82 ± 1.33% two years thereafter, and 7.62 ± 0.80% vs. 7.79 ± 1.19% three years thereafter. There were no significant changes in HbA1c from baseline throughout follow-up. BMI and insulin requirements were similar and remained unchanged in volunteers and controls: mean BMI-SDS one year before enlistment age was 0.23 ± 0.83 vs. 0.29 ± 0.95, at enlistment age 0.19 ± 0.87 vs. 0.25 ± 0.98, one year thereafter 0.25 ± 0.82 vs. 0.20 ± 0.96, two years thereafter 0.10 ± 0.86 vs. 0.15 ± 0.94, and three years thereafter 0.20 ± 0.87 vs. 0.16 ± 0.96. Mean insulin dose in U/kg/day one year before enlistment age was 0.90 ± 0.23 vs. 0.90 ± 0.37, at enlistment age 0.90 ± 0.28 vs. 0.93 ± 0.33, one year thereafter 0.86 ± 0.24 vs. 0.95 ± 0.33, two years thereafter 0.86 ± 0.21 vs. 0.86 ± 0.29, and three years thereafter 0.87 ± 0.23 vs. 0.86 ± 0.28. There were no episodes of severe hypoglycemia or DKA in either group. 

Conclusions: Our data indicate that during voluntary national service young adults with T1D maintain metabolic control similar to that of non-volunteers. 

 

Background: Hypovitaminosis D is common worldwide, even in sunny regions.

Objectives: To assess the prevalence and determinants of vitamin D deficiency in toddlers.

Methods: A cross-sectional prospective study was conducted in healthy Jewish children aged 1.5–6 years at five primary care pediatric clinics in the Jerusalem area during the period October 2009 to November 2010. Parents were interviewed regarding personal and demographic data and sun exposure. Blood samples were obtained for serum 25-hydroxyvitamin D [25-OHD] level. Vitamin D deficiency and insufficiency were defined as 25-OHD < 20 ng/ml and < 30 ng/ml, respectively.

Results: Of 247 children studied, 188 (76%) were ultra-Orthodox and 59 (24%) were Orthodox, traditional or secular. Mean (± SD) 25-OHD level was 25.7 ± 10 ng/ml. Only 73 children (29.6%) had sufficient 25-OHD levels, 104 (42.1%) had insufficiency, and 70 (28.3%) had 25-OHD deficiency. The difference between ultra-Orthodox and others was insignificant (25 ± 10 vs. 27.8 ± 10.5 ng/ml respectively, P = 0.062). Children aged 1.5–3 years had higher 25-OHD levels than those aged 3–6 years (28.6 ± 10.7 and 24 ± 9.2 ng/ml respectively, P < 0.001). Vitamin D deficiency was more common in winter (53%) and autumn (36%) than in summer (19%) and spring (16%). Toddlers attending long-day kindergartens had higher 25-OHD level than those staying at home or at short-day kindergartens (28.8 ± 11.5 and 24.7 ± 9.6 ng/ml respectively, P < 0.05).

Conclusions: A high prevalence of vitamin D deficiency was found in toddlers in our study, mainly in older children and in the winter and autumn. We recommend routine supplementation of vitamin D for children beyond the agear.

Background: Maternal exposure to alcohol during pregnancy can lead to a wide range of clinical manifestations in their offspring, termed fetal alcohol spectrum disorder (FASD). In Israel, relatively few cases of FASD have been diagnosed and the prevalence has not been systematically evaluated.

Objectives: To determine the number of children with FASD or at risk for FASD in a select population of high risk patients seen at a clinic evaluating foster and adopted children.

Methods: Israeli children under 2 years old who were candidates for domestic adoption or in foster care were prospectively evaluated for clinical manifestations of FASD, and information was obtained regarding parental use of alcohol or other illicit drugs.

Results: Of the 100 patients prospectively evaluated, 8 had mothers with a known history of alcohol consumption during pregnancy. Two of the children had fetal alcohol syndrome (FAS) without known maternal exposure to alcohol and two had partial FAS. Eleven other children were at risk for development of one of the diagnostic categories of FASD.

Conclusions: In a population of pre-adoption and foster children, 15% either had manifestations of FASD or were at risk for developing FASD. Although this is a select high risk population, the data from this study strongly suggest a greater prevalence of FASD than previously assumed. Under-diagnosis of FASD is detrimental to affected children who could benefit from interventions designed to meet the needs of FASD victims.
 

Background: Down syndrome is one of the most common chromosomal abnormalities. Children and adults with DS[1] have significant medical problems and require life-long medical follow-up.

Objectives: To determine the adequacy of medical surveillance of individuals with DS as recommended by the American Academy of Pediatrics.

Methods: The study was conducted at a multidisciplinary center specializing in the care of DS during the period 2004–2006. At their first visit to the Center, caregivers of individuals with DS were questioned about the medical status of their child including previous evaluations. Medical records brought in by the parents were reviewed.

Results: The caregivers of 150 individuals with DS (age ranging from newborn to 48 years old, median age 5 years) were interviewed and medical records were reviewed. The prevalence of specific medical problems differed between our population and the reported prevalence from other surveys. For example, 39.3% of our population had documented auditory deficits while the reported prevalence is 75%. For gastrointestinal and thyroid disease, the prevalence was higher in the studied population than that reported in the literature. In terms of compliance with the AAP[2] recommendations, most children (94%) underwent echocardiography, but only 42.7% and 63.3% had been tested for auditory or visual acuity respectively. Only 36.3% over the age of 3 years had cervical spine films.
Discussion: Many individuals with DS are not receiving appropriate medical follow-up and the implications of inadequate surveillance can be serious
