[Mucoviscidosis and marathon running. Evaluation of physical endurance in patients with cystic fibrosis].

The authors give a survey on the problems of sport activities in CF patients, which is based on own experience and the data of the literature. All these patients should take part in endurance sport. The regular training program should be carefully planned according to the state of each single patient. Regular medical supervision of it is necessary. Only in selected cases CF patients, too, can take part in marathon races.

[Pulmonary complications in AIDS].

Adult patients suffering from infection with the HIV-virus acquire pneumocystis carinii pneumonia in nearly 80 per cent and in the half of all patients the basic disease AIDS has been detected by this lung infection. In childhood the patients with AIDS show most frequently interstitial lung diseases due to pneumocystis carinii or to lymphoid interstitial pneumonia. Also recurrent bacterial pneumonia may frequently occur, likewise infections with the cytomegalovirus or the Epstein-Barr-virus causing atypical pneumonia. The identification of the aetiology of these lung diseases is more difficult in children than in adults. In future it should be necessary to include more often AIDS as the basic disease into the differential diagnostic considerations in cases of such lung infections.

[Malignant tumors of lungs and bronchi in children and youths. 1. Compilation of 175 cases from the literature].

The authors collected data of 175 malignant and semimalignant tumors in children and adolescents. 74.3 per cent of all reported cases were epithelial tumors (44.0 per cent bronchial adenomas and 30.3 per cent carcinomas), 15.4 per cent of embryonal and 10.3 per cent of mesenchymal origin. All age groups were affected. In children under one year of age embryonal tumors prevailed, in preschool age carcinomas and embryonal tumors dominated while in schoolchildren more often bronchial adenomas and carcinomas were found. All these tumors are very unusual in the pediatric age group. Therefore the right diagnosis is often missed for a longer time.

[Bronchopulmonary infections in mucoviscidosis].

Cystic fibrosis (CF) is the most common genetic disease of Caucasians and also the most important lung disease of the first decades of life associated with infections by a variety of bacteria species especially Pseudomonas aeruginosa and Staphylococcus aureus. During the last two decades chronic Pseudomonas infection has emerged as the most difficult problem. Pseudomonas bacteria are able to synthesize numerous extracellular factors (virulence factors) contributing to its pathogenicity. Immunological defense mechanisms against Pseudomonas (and other bacteria species) have been demonstrated, but a complete elimination from infected lungs has not been observed. Therapy of Pseudomonas infections includes frequently combinations of antibiotics of the beta-lactam and aminoglycoside type.

[Acute foreign body aspiration as a respiratory emergency in childhood].

From 1957 to 1987 altogether 206 cases of tracheobronchial foreign body aspiration were diagnosed. Two third of the patients were one or two years old. Boys prevailed with 57 per cent. 55 per cent of all foreign bodies were nuts. Only 10 per cent were radiopaque (screws, nails, needles or pieces of bones). The attempt to eliminate the foreign body via the bronchoscope was successful in 96 per cent and failed in seven cases. Six children had to undergo a thoracotomy. In one third of the cases the foreign body remained two weeks or longer in the bronchial tree. 66 children with such a "chronic" foreign body were later on examined by bronchography, which showed in 29 per cent severe deformations of the bronchial wall and in 14 per cent even bronchiectasis. An acute foreign body aspiration should always be considered and handled as an emergency.

[Significance of stenoses of the main bronchus within the scope of congenital abnormalities of the respiratory tract].

During a period of 23 years (1962 to 1984) we found 197 children with stenoses of the main bronchi among 2,000 bronchological first examinations of children suffering from chronic or recurring bronchopulmonary diseases. In 75 children these stenoses were combined with those of the trachea, in 122 children they were restricted to the main bronchi. The left main bronchus showed an predominant incidence of 85 per cent. Only in 5 cases an extrabronchial cause could be established by anomalous vessels. In the main part of the patients we found intramural stenoses due to congenital circumscribed malazia or to complete aplasia of the bronchial cartilage. The clinical symptoms of a recurring obstructive bronchitis were predominating in nearly 80 per cent of the patients. By follow-up investigations of 65 children with an average duration of 8 years no deaths had occurred. Forty children (65 per cent) were without any complaints and could be physically loaded in a normal way, whereas 21 children showed persistent mild or moderate complaints. In two patients with cystic fibrosis and two others without this basic disorder bronchiectases had developed distal of the stenoses. Bronchological controls after an average follow-up of 3 1/2 years showed in 60 per cent of the children still unchanged stenoses and deforming changes of the bronchial wall distal of the stenoses in contrast to the more favourable clinical findings.

[Bronchologic studies in East Germany: current status and perspectives].

Within a period of 8 years (1979 to 1986) there were performed in 21 centres of the German Democratic Republic 15,049 bronchoscopic investigations (in 49.6 per cent combined with a subsequent bronchography) in 11,717 children, including 2,054 (17.5 per cent) up to one year of age. The detailed analysis shows important trends, which allow a reasonable prognosis of the perspectives of pediatric bronchology in the GDR.

Bronchial secretions and bronchial mucosa in children with cystic fibrosis: comparison of bronchoscopic, biochemical, bacteriological, microscopic and ultrastructural findings.

In children (mean age 12.1 +/- 2.9 years) with cystic fibrosis, 44 bronchoscopic examinations were done under general anaesthesia with muscle relaxation using a Friedel type ventilation bronchoscope. The endoscopic picture of the mucous membranes was compared with the state of the bronchial secretions, its bacteriologic findings and content of acid mucopolysaccharides and DNA fibres (semiquantitative estimations). In all patients biopsy of the mucous membrane (central part of the bronchial tree) was performed for light and electron microscopy. The degree of reddening, swelling of the mucous membrane and hypersecretion was in some agreement with the intensity of the cellular infiltration and the production of pus (microscopic investigation). Secondary ultrastructural changes were detected in nearly all children, consisting of cellular oedema, swelling of mitochondria, dilatation of the endoplasmatic reticulum, protrusion of cells and fusion of cilia, enlarged intercellular spaces, thickening of the epithelial basal membrane, increased number of goblet cells, microtubular abnormalities of the cilia, lesions of the apical cell membrane with loss of cilia and microvilli. These ultrastructural changes were not correlated with the above-mentioned signs of inflammation.
