Comparative Study[A technical inhalation test variant for improving the effectiveness of the use of dose aerosols].
We compared the airway responsiveness to beta 2-agonist aerosol inhalation with two breathing techniques for bronchodilator testing in 25 patients with COPD. Open breathing technique showed better results than closed breathing technique. Causes for these results like optimization of volume and flow conditions for aerosol deposition are discussed.

Since 1980 an increase of the frequency of osteomyelitis after BCG vaccination has been described by some european countries. In the GDR osseous impairments as BCG complication are rarely. The authors report on an 18 months old boy with lesions of the distal tibia and the ankle-joint. ⋯ In contrast to the local findings general symptoms were unimportant. The surgical treatment was completed by antituberculotic chemotherapy. This treatment was successful.
