OBJECTIVE Obstructive sleep apnea (OSA) in children is usually effectively treated by adenotonsillectomy (T&A). However, there may be a waiting list for T&A, and the procedure is associated with an increased risk of postoperative complications in children with OSA. Needed is a simple test that will facilitate logical prioritization of the T&A surgical list(More)
OBJECTIVE To elaborate and validate a Preschool Respiratory Assessment Measure (PRAM) that would accurately reflect the severity of airway obstruction and the response to treatment in young patients with asthma. STUDY DESIGN A prospective cohort study was performed in 217 children aged 3 to 6 years who presented to a pediatric emergency department with(More)
Sixty-eight cases of uterine prolapase in pastured dairy cows were treated in 2 consecutive spring calving seasons in East Gippsland, Victoria. Fifty cows survived (73.5%). Of 43 cows available for followup, 36 (84%) conceived in the mating period following the prolapse, taking 10 d longer to conceive than herd mates that calved on the same day. Three of(More)
BACKGROUND Although patients with myelomeningocele and the Chiari II malformation are known to have sleep apnea and respiratory control deficits, the prevalence, types, severities, and associations of sleep-disordered breathing (SDB) have not been adequately defined. METHODS A cross-sectional study of our myelomeningocele clinic population was undertaken(More)
In order to assess the efficacy of a combination of systemic and nebulized corticosteroids in reducing the incidence and severity of chronic lung disease (CLD) in very low birthweight (VLBW) infants, 60 ventilator-dependent infants < or = 1500 g were randomly assigned to receive either steroids or placebo as of 7 d. The steroid group (n = 30, GA = 25.8 +/-(More)
The appropriate management of pediatric empyema thoracis remains controversial. The authors reviewed 47 cases of empyema thoracis over a 26-year period. The management of empyema included initial diagnostic thoracentesis and classification as acute, fibropurulent, or chronic. If the empyema was "acute," therapeutic tap, tube thoracostomy, or no surgical(More)
Externally recorded systolic time intervals (STI's), indirect (CO2 re-breathing) cardiac output, and auscultatory blood pressures were measured during upright bicycle ergometer work in 20 healthy men, aged 24-56 yr. The subjects were studied on 2 separate days at steady-state work loads chosen to represent light (mean heart rate (HR) = 96 beats.min-1),(More)
There is limited information concerning the exercise performance of long-term survivors of bronchopulmonary dysplasia (BPD), and much of what is available pertains to those with relatively mild disease. The present study was undertaken to describe exercise responses in patients with a history of severe BPD, defined as those patients with a clinical and(More)
OBJECTIVE To evaluate the long-term pulmonary sequelae of survivors of bronchopulmonary dysplasia (BPD) of sufficient severity to have required supplemental oxygen for at least 1 month after term. STUDY DESIGN Fifteen patients with a mean age of 1.1 years were matched to preterm infants of similar gestational age and age at time of study. Pulmonary(More)
