Sixty-nine patients (age 10 +/- 3.5 years, median 9.7 years) operated on for tetralogy of Fallot, underwent exercise testing 5.1 +/- 2.5 years after total correction. Aerobic capacity was assessed by the ventilatory threshold method. After the exercise test, parents completed a validated standardized questionnaire to evaluate the habitual level ...

Cardiovascular function accounts for endurance performance and, by a rapid increase in oxygen supply at the onset of exercise, contributes to short-lasting intensive exertion prevailing in many kinds of sports activities. This study determined the time for oxygen uptake (VO2) to reach one half of its asymptotic level above rest, ...

Exercise participation, perceived barriers to exercise, and perceived benefits of exercise were analyzed in a large random sample of urban women ages 20-49 (N = 1,113). Although mothers and women without children perceived similar benefits of exercising, mothers were much less active than women without children. The differences were greatest ...

To investigate ways in which young people's attitudes about, and motivation for, exercise vary with the levels of exercise they take, a self-completed questionnaire was given to 382 children aged 14-15 in two secondary schools in Devon. It was found that the high exercisers (defined by those in the highest ...

Reproducible, exercise-induced anaphylactic reactions occur in some patients only after certain foods have been eaten before exercise. We describe a patient in whom hazelnuts were a triggering factor for exercise-induced anaphylaxis. Skin tests and RAST were positive for nuts and grass and weed pollen. The exercise challenge test after hazelnut ...

The outcome of surgical palliation was evaluated in 26 children with complex cyanotic congenital heart disease.

The splint was remodeled periodically. At the time of ...

Nitrazepam was used in the treatment of resistant myoclonic epilepsy in 38 children. After the occurrence of nitrazepam-associated swallowing incoordination, high-peaked esophageal peristalsis and related bronchospasm in one patient, we initiated a prospective study of esophageal manometry using a station pull-through technique with a pediatric 4-channel continuous perfusing system. Three ...

Chest pain in children and adolescents, unlike in adults, is rarely of cardiac origin and its etiology is frequently unknown. In this age group, chest pain can limit normal activity and sports participation. The reported incidence of exercise-induced asthma in children with chest pain is less than 20%. For this ...

The purpose of this study was to examine the effect of parental involvement in a school-based program about exercise and nutrition. One fifth grade and one sixth grade class were randomly assigned to each of the three different treatment conditions, a school-and-home condition (n = 45), a school-only condition (n ...

Injuries to children related to exercise bicycles can result in significant morbidity, but are almost entirely preventable. To forestall these injuries, manufacturers should continue to focus their attention on improved design and developing safer equipment. In addition, pediatricians and other primary care providers need to play a role in educating ...

A 58-year-old farmer was admitted to our hospital because of repeated episodes of anaphylaxis. He had experienced 12 episodes of anaphylactic shock over the previous 17 years. These attacks included three episodes of bee sting. In general, the episodes occurred during farm work (exercise) and within two hours of eating ...

The glycoconjugate component of cystic fibrosis (CF) epithelial secretions is abnormally sulfated. Previous studies have suggested that some but not all CF fibroblasts express this secondary defect. We tested the hypothesis that the major CF mutation (delta F508/delta F508) is correlated with elevated sulfate transport, by measuring the rates of ...
