Sugarsquare, a Web-Based Patient Portal for Parents of a Child With Type 1 Diabetes: Multicenter Randomized Controlled Feasibility Trial.

Background: Raising a child with type 1 diabetes (T1D) means combining the demands of the disease management with everyday parenting, which is associated with increased levels of distress. A Web-based patient portal, Sugarsquare, was developed to support parents, by providing online parent-professional communication, online peer support and online disease information.

Objective: The first aim of this study was to assess the feasibility of conducting a multicenter, randomized controlled trial in Dutch parents of a child with T1D.

Ulcerative colitis presenting as acute infectious gastroenteritis with a paralytic ileus.

A 15-year-old girl who presented with signs of acute infectious gastroenteritis, just as two members of her family is described. As the patient did not improve, a sigmoidoscopy was performed and the diagnosis of ulcerative colitis (UC) was made. Our hypothesis is that an infection triggered the development of UC.

Dose-responses over time to inhaled fluticasone propionate treatment of exercise- and methacholine-induced bronchoconstriction in children with asthma.

When treating bronchial hyperresponsiveness to so-called direct and indirect stimuli, distinct pathophysiological mechanisms might require differences in dose and duration of inhaled corticosteroid therapy. To test this hypothesis in children with asthma, we investigated the time- and dose-dependent effects of 2 doses of fluticasone propionate (FP, 100 or 250 microg bid.) in improving exercise- (EIB) and methacholine-induced bronchoconstriction during 6 months of treatment, using a placebo-controlled parallel group study design.

Occurrence of a late response to exercise in asthmatic children: multiple regression approach using time-matched baseline and histamine control days.

At the present time, there is still controversy concerning the presence of a late asthmatic response (LAR) to exercise challenge in asthma. We have, therefore, investigated the occurrence of a LAR after exercise in asthmatic children visiting an out-patient clinic, using time-matched baseline and histamine control days, and a statistical analysis according to recently published recommendations. After a screening exercise day, 17 children (aged 7-14 yrs) randomly performed, on three subsequent study days, either: a second standardized exercise challenge; or a histamine challenge whilst matching the bronchoconstriction after exercise; or measurement of baseline lung function without any challenge.

Prolonged recovery from exercise-induced asthma with increasing age in childhood.

It has been suggested that children with asthma recover more quickly from exercise-induced bronchoconstriction than adults. On the basis of clinical observation we hypothesized that recovery rate from exercise-induced asthma (EIA) in childhood also decreases with age. In 14 children (aged 7-12 years) with a history of EIA, we measured spontaneous recovery from bronchoconstriction induced by two different stimuli: exercise and histamine.
