Hypertrophic cardiomyopathy in Donohue syndrome.

We report the case of a patient with Donohue syndrome who died of heart failure due to obstructive hypertrophic cardiomyopathy. A literature survey revealed that hypertrophic cardiomyopathy was present in 30% of these patients and was often fatal. Therefore, every patient with Donohue syndrome should be screened for hypertrophic cardiomyopathy.

Cardiovascular and metabolic outcome in 6-8 year old offspring of women with type 1 diabetes with near-optimal glycaemic control during pregnancy.

Background: High maternal glucose concentrations during diabetic pregnancy may lead to health problems in the offspring later in life. We showed in a previous nationwide study on pregnancy outcome in type 1 diabetic women that prepregnancy care was good and a near-optimal glycaemic control during pregnancy was achieved (mean HbA1c 6.2%).

Bone mineral density in children with moderate to severe atopic dermatitis.

Background: Low bone mineral density (BMD) has been reported in 30.4% of adult patients with atopic dermatitis (AD).

Objective: The aim of this study was to determine the prevalence of low BMD in children with moderate to severe AD and to investigate the relation between BMD and corticosteroid and cyclosporine therapy.

Risk factors for childhood overweight in offspring of type 1 diabetic women with adequate glycemic control during pregnancy: Nationwide follow-up study in the Netherlands.

Objective: Pregnancy in type 1 diabetic women remains a high-risk situation for both mother and child. In this study, we investigated long-term effects on body composition, prevalence of overweight, and insulin resistance in children of type 1 diabetic women who had had adequate glycemic control during pregnancy (mean A1C 6.2%), and we related their outcome to perinatal factors, including macrosomia (birth weight >90th percentile).

Unmasking of a hemizygous WFS1 gene mutation by a chromosome 4p deletion of 8.3 Mb in a patient with Wolf-Hirschhorn syndrome.

The Wolf-Hirschhorn syndrome (WHS (MIM 194190)), which is characterized by growth delay, mental retardation, epilepsy, facial dysmorphisms, and midline fusion defects, shows extensive phenotypic variability. Several of the proposed mutational and epigenetic mechanisms in this and other chromosomal deletion syndromes fail to explain the observed phenotypic variability. To explain the complex phenotype of a patient with WHS and features reminiscent of Wolfram syndrome (WFS (MIM 222300)), we performed extensive clinical evaluation and classical and molecular cytogenetic (GTG banding, FISH and array-CGH) and WFS1 gene mutation analyses.
