The prevalence of asthma was determined by a parental questionnaire in 9403 schoolchildren aged 9-11 years. A cold air challenge was done in 7248 of these children to test for bronchial hyperresponsiveness. Regarding the doctor diagnoses of asthma as reported by the parental questionnaire the specificity of the cold air challenge was 92.5%, the sensitivity 28.7%, the positive predictive value 9.1% and the negative predictive value 98%.

An aneurysm of the aorta with aortobronchial fistula formation was seen in a 33 year old patient as a rare cause of recurring hemoptysis. 18 years previously he had undergone surgery of coarctation of the aorta. By means of different imaging methods the diagnosis was established in time and the aneurysm resected, so that the patient survived this mostly fatal incident.

Case Reports
[Tracheobronchopathia osteochondroplastica and coexistent mucoepidermoid carcinoma of the lung: Case report].
Pneumonia of the middle lobe that had been diagnosed by x-ray in a male patient of 51 years of age did not recede completely despite antibiotic treatment. CT showed a space-occupying growth in the middle lobe of about 1.5 cm size, with consecutive atelectasis. Bronchoscopy revealed a pronounced pattern of tracheobronchopathia osteochondroplastica, but it was not possible to confirm the middle lobe syndrome (Brock's syndrome) by histological examination. A mucoepidermoid carcinoma of the middle lobe was histologically established by thoracotomy besides the tracheobronchopathia osteochondroplastica. 9 months post-operatively there is no pointer to any recurrence or metastasising.
