Comparative StudyFrequency and timing of recurrent events in infants using home cardiorespiratory monitors.
To determine the incidence, type, timing, and factors predictive of recurrent significant events in infants with home cardiorespiratory monitors. ⋯ Because most apnea, bradycardia, and recurrent clinical events began during the first month of monitoring, we emphasize the need for vigilant follow-up care of infants immediately after institution of home monitoring. Readmission for investigation is warranted in infants with severe or multiple recurrent events.

Randomized Controlled Trial Comparative Study Clinical TrialEarly nebulized budesonide in the treatment of bronchiolitis and the prevention of postbronchiolitic wheezing.
To determine the effectiveness of nebulized budesonide in the treatment of acute bronchiolitis and in the prevention of postbronchiolitic wheezing. ⋯ This study did not demonstrate that a 6-week course of nebulized budesonide reduced the symptoms of acute bronchiolitis or prevented postbronchiolitic wheezing.

Comparative StudyUltrasonographic and clinical predictors of intussusception.
The objective of this study was to determine the positive and negative clinical predictors of intussusception and the correlation of ultrasonography and air enema in establishing this diagnosis. ⋯ Excellent positive predictors of intussusception were identified prospectively. Although no reliable negative predictors were found, patients at low risk may be screened by ultrasonography.

Intravenous correction of neonatal hypomagnesemia: effect on ionized magnesium.
Neonatal hypomagnesemia is defined as total magnesium (TMg) < or = 0.65 mmol/L (1.6 mg/dl). However, magnesium (Mg) deficiency and sufficiency overlap at serum values of 0.57 to 0.74 mmol/L (1.4 to 1.8 mg/dl). We hypothesized that (1) some infants with TMg < or = 0.65 mmol/L (1.6 mg/dl) have normal ionized Mg values (normal neonatal range 0.40 to 0.56 mmol/L (0.97 to 1.36 mg/dl)); (2) the dose (6.0 mg of elemental Mg/kg) used to correct hypomagnesemia does not lead to elevation of ionized Mg; (3) after intravenous magnesium sulfate infusion, ionized calcium increases in patients with low baseline ionized Mg and decreases in patients with normal baseline ionized Mg. ⋯ (1) Measurement of ionized Mg should prevent overdiagnosis and treatment of hypomagnesemia. (2) The dose used in this study is safe. (3) Ionized Mg concentrations are inversely correlated to the response of ionized Ca concentrations to an Mg load.

Comparative StudyGrowth status in children with cystic fibrosis based on the National Cystic Fibrosis Patient Registry data: evaluation of various criteria used to identify malnutrition.
The objectives of this study were to determine growth status and to identify malnutrition with various anthropometric indicators in children with cystic fibrosis (CF) based on cross-sectional analysis of the 1993 National CF Patient Registry data. ⋯ Twenty percent of all children in the 1993 National CF Patient Registry were <5th percentile for height- or weight-for-age. A significant discrepancy was found when different criteria were used to distinguish "stunting" versus "wasting" in malnourished children with CF.
