Case 1 A 53-year-old chemical worker had an accidental exposure to uranium hexafluoride gas at work in a chemical plant on Nov 12, 1968. He was not wearing a respiratory protective device and breathed uranium hexafluoride vapors for about 15 minutes. He immediately developed shortness of breath and cough and was subsequently taken to an […]

The study groups were relatively small in most of the reports. Only four studies had more than 20 subjects who completed the protocol (Table 1). This raises concerns that a beta error may have masked a beneficial effect of medical antireflux therapy. The average change in FEV1 in these studies was less than 5%, with […]

These studies may have been too short to allow the complete benefit from antireflux therapy to become apparent. One surgical series presented 5-year follow-up data indicating an improvement in lung function. One half of the patients in another study were free of respiratory symptoms 77 months after antireflux surgery. Perhaps improvement in pulmonary function would […]

Because there have been relatively few studies using each antireflux medication, all of the English-language, peer-reviewed, placebo-controlled studies of the effects of antireflux medication on asthma were combined for analysis. The inclusion of studies using the different antireflux regimens is justified by the similarity of their outcomes. The combined data show that the majority of […]

The subjects were divided into treatment responders and nonresponders. Improvement was defined by the presence of at least one of the following: asthma symptom score reduction of more than 20%, PEF improvement by more than 20%, total number of asthma medications required was reduced by more than 20%, or daily prednisone dose reduction by more […]

Ford et al studied the effects of omeprazole, 20 mg daily for 4 weeks, in 11 patients with both asthma and GER in a randomized, double-blind, placebo-controlled, crossover protocol. There was a 1-week run-in period at the beginning of the study and a 1-week washout period between treatment periods. No improvement in GER or asthma […]

Fifteen patients with asthma and GER were treated with ranitidine, 450 mg daily for 7 days in a blinded, crossover, placebo-controlled study with only a 3-day washout period between treatments The treatment period was too short for GER symptoms to improve. No improvements in asthma symptoms, asthma medication use, or PEFR were demonstrated in this […]
