The lateral capitellohumeral angle in normal children: mean, variation, and reliability in comparison to Baumann's angle.

Background: Angular deformity is the most common complication of supracondylar humerus fracture. Baumann's angle (BA) is an established radiographic measure of coronal plane deformity after this injury. Numerous radiographic methods have been used to assess sagittal plane deformity, however, the mean, variability, and reliability of these measures has not been established.

Pulmonary exacerbations are associated with subsequent FEV1 decline in both adults and children with cystic fibrosis.

Background: Patients with cystic fibrosis (CF) frequently experience pulmonary exacerbations that may lead to a faster subsequent decline in pulmonary function; however, this relationship has not been clearly established. The purpose of this study was to determine the association between the frequency of pulmonary exacerbations and subsequent forced expiratory volume in 1 sec (FEV(1) ) decline in adults and children with CF.

Methods: Cohort study of subjects followed in the Cystic Fibrosis Foundation Patient Registry from 2003 through 2006.

Failure to recover to baseline pulmonary function after cystic fibrosis pulmonary exacerbation.

Rationale: Patients with cystic fibrosis periodically experience pulmonary exacerbations. Previous studies have noted that some patients' lung function (FEV(1)) does not improve with treatment.

Objectives: To determine the proportion of patients treated for a pulmonary exacerbation that does not recover to spirometric baseline, and to identify factors associated with the failure to recover to spirometric baseline.

Compliance with multiple-dose vaccine schedules among older children, adolescents, and adults: results from a vaccine safety datalink study.

Objectives: We studied compliance with multiple-dose vaccine schedules, assessed factors associated with noncompliance, and examined timeliness of series completion among older children, adolescents, and adults.

Methods: We conducted a large, multisite, retrospective cohort study of older children, adolescents, and adults in the Vaccine Safety Datalink population from 1996 through 2004. We quantified the rates of completion of all required doses for varicella, hepatitis A, and hepatitis B vaccines according to their recommended schedules.
