[Etiological, clinical and roentgenological aspects of mediastinal emphysema in children and adolescents].

The authors publish 8 cases of emphysema of the mediastinum in childhood and adolescence. The aetiologic variety and the radiologic symptoms are presented. Chronic diseases of the lungs and the respiratory tract, injuries of the thorax or iatrogenic genesis are the cause of emphysema.

The eosinophilic granulocyte count in the respiratory secretions of children with chronic nonspecific respiratory diseases.

We performed cytologic evaluations of 6116 nasal and/or bronchial smears from 4510 patients (average age: 7.6 years; 3 months--17 years) suffering from different kinds of chronic nonspecific respiratory diseases (CNSRD); in 137 children (average age: 4.8 years) undergoing bronchologic examinations under general anesthesia we compared the findings with those for bronchoalveolar lavage (BAL).

Serum prolactin concentration and hypothalamic-pituitary hormone release in CF-children.

Some experimental data from animals suggest that prolactin (PROL) is involved in sweat production and modulates the chloride concentration of sweat. We determined the serum PROL level by RIA in 38 CF-patients (age: 3-24 years) and 48 patients with bronchial asthma (age: 2-18 years) and found no concentration differences between the two groups each taken as a whole; the TSH level was increased in CF (p less than 0.05).

[A contribution to the frequency and assessment possibilities of chronic aspecific respiratory tract diseases (CARD)--an epidemiological study in the mostly agricultural district of Neubrandenburg].

A test was carried out in order to determine representative information on CNSRD prevalence in children at the age of 3 to 15 and to check possibilities of registration. A clinical examination was performed at a totality of 122,400 children of a district, a sample test of 2,927 children was carried out. 10% of the children suffer from chronic diseases of the respiratory tract.
