Sinus disease has been described as one of several aggravating factors for chronic adult-onset asthma. Forty-eight children whose reactive airway disease (asthma) was significantly improved with treatment of their sinusitis have been observed. All of the subjects were seen in the office with chronic (more than 3 months) respiratory symptoms; all had daytime(More)
Forty of 82 patients with recurrent pneumonias and/or clinical asthma were found to have gastroesophageal reflux (GER) by the criteria of two or more of five tests positive for GER. Of 36 patients with GER followed for response to therapy, 32 patients attempted medical therapy and four had fundoplications. Ten of 32 (31%) patients on medical therapy had(More)
IMPORTANCE Newborn screening for severe combined immunodeficiency (SCID) using assays to detect T-cell receptor excision circles (TRECs) began in Wisconsin in 2008, and SCID was added to the national recommended uniform panel for newborn screened disorders in 2010. Currently 23 states, the District of Columbia, and the Navajo Nation conduct population-wide(More)
To evaluate the role of gastroesophageal reflux (GER) as a possible cause of recurrent pulmonary disease, 30 children, aged 1 to 18 years, were studied prospectively with esophageal function tests. These included esophagram (30 patients), esophageal manometry (29 patients), pH probe (Tuttle) test (29 patients), and esophagoscopy with esophageal biopsy (23(More)
OBJECTIVE To evaluate the effectiveness of inhibiting the formation of the 5-lipoxygenase products of arachidonic acid by the 5-lipoxygenase inhibitor zileuton in the treatment of mild-to-moderate asthma. DESIGN Randomized, double-blind, placebo-controlled study. SETTING University hospitals and private allergy and pulmonary practices. PATIENTS A(More)
A Nebulizer Chronolog, a portable device that houses a standard nebulizer canister, was used in a unique method to measure compliance with aerosolized medication. Each actuation is tabulated to within 4 minutes of the actual time of usage and can subsequently be displayed in a day-hour-minute format. Of the 19 patients studied for 12 weeks with a(More)
A total of 151 children with severe atopic bronchial asthma were screened for AAT levels by the STIC and RID methods. They were also phenotyped by the method of acid starch electrophoresis and crossed immunoelectrophoresis. The results were compared with those in a like control age group of children without known pulmonary problems. Both groups revealed(More)
A broad antiallergic compound called azelastine was studied pharmacodynamically in 34 subjects to correlate bronchodilator effect with blood levels of azelastine and desmethyl azelastine, its major metabolic product in man. Despite azelastine and desmethyl azelastine blood levels that were proportionate to the dosage range, the bronchodilator effect as(More)
