In a randomized, cross-over study we compared the effects of inhaled nedocromil sodium, 4 mg q.i.d., with inhaled beclomethasone dipropionate, 200 micrograms q.i.d. in 23 atopic asthmatic patients. After a 3 week single-blind placebo period, regarded as the baseline, and after 4 and 8 weeks of active treatment, drug effects were assessed with regard to(More)
BACKGROUND From 2007 to 2009, The Netherlands experienced a major Q fever epidemic, with higher hospitalization rates than the 2-5% reported in the literature for acute Q fever pneumonia and hepatitis.
