[Dynamic pulmonary densitography in the diagnosis of radiographically non-contrasting foreign bodies in the lower respiratory tract in children].

Densitographic examination of the regional pulmonary ventilation is a non-pretentious and non-invasive method which can be used even in very young children, which when aspiration of a non-contrasting foreign body is suspected can confirm by revealing localized bronchial obstruction the presence of a foreign body and determine its localization in the tracheobronchial tree. By repeated records of adequate ventilation at rest in all pulmonary fields it is possible with a minimal radiation load to rule out the suspicion and the child need not be subjected to an endoscopic examination. In five children aged 19 months to 13 years the usefulness of this procedure for the diagnosis of aspiration of a non-contrasting foreign body was proved, as the physical and skiagraphic finding was not convincing, there was discrepancy of anamnestic data and results of repeated skiagraphic examinations, negative auscultation and negative X-ray examination after an anamnestically obvious cse of aspiration, it ws used, for a more accurate localization of the aspired object, and to confirm localized obstruction of pulmonary ventilation in a chronic foreign body of plant origin in the airways.

[Regional lung ventilation in the differential diagnosis of aspiration of roentgenologically non-detectable foreign bodies].

A densitographic evaluation of regional lung ventilation represents a positive contribution also for the diagnosis of x-ray non-contrast foreign bodies aspiration, especially when both physical and skiagraphic findings are unconvincing. Dynamic lung densitography is a convenient undemanding method, that can be used even in the youngest children. In 5 adults and 4 children proven localized bronchial obstruction confirmed the suspicion of aspiration of non-contrast foreign body.

[Cryocoagulation in the treatment of bronchial tumors].

From 1987 to 1989 22 men and one woman with morphologically certified tumors of the lungs were symptomatically treated with cryocoagulation. The cryoequipment KNF 4/5 with 30 W freezing capacity was used. After treatment in 20 out of 22 patients an objective improvement could be observed.

[Disorders of pulmonary ventilation in children with adenoid vegetations].

In a group of children aged 4 to 13 years with hypertrophic adenoid vegetation the pulmonary ventilation and mechanics of respiration were examined by global and regional spirography, incl. evaluation of VC, FEV1%, RV, IGV and V-V loops and in six children by whole-body plethysmography. While during global spirography a pathological finding was recorded in 31%, during regional spirographic examination pathological changes of the mentioned functional values were recorded in 86% of the children, which provides evidence that regional spirography combined with the densitographic method can reveal local disorders of pulmonary ventilation which cannot be detected by global spirography.

Disseminated pulmonary adiaspiromycosis identified in bioptic material from the lung.

A disseminated form of pulmonary adiaspiromycosis was estimated in a 48 year old miner. The origin of a hypersensitivity mainly of an immediate allergic type became evident during an immunological examination and was partly indicated also by the tissue reaction and by elevated level of serum IgE (480 I.U.

[The cooperation of pneumonologist and allergologist in the care of patients with bronchial asthma (author's transl)].

The initial manifestation of atopic bronchial asthma belongs in diagnostics and therapy into the field of the allergologist. But the services of the specialty tuberculosis and respiratory diseases can assist especially with hospital treatment in this care because the services for allergology in the policlinical departments for internal medicine and pediatrics do not dispose of bed capacities of their own. The cooperation of the specialty tuberculosis and respiratory diseases is appropriate in the dispensaire care and hospital treatment of asthmatics especially in those cases, when there is an infect-induced asthma, if any other respiratory diseases exist as complications of bronchial asthma or if disturbances of pulmonary function supervene.

Reflection of passive exposure to smoking in the home on the prevalence of chronic bronchitis in non-smokers.

Analysis of data assembled in an epidemiological investigation of 123 235 adults from three districts of the West Bohemian region incl. 57 217 male non-smokers from a total of 66 806 and 23 473 male non-smokers from a total number of 56 429 males revealed a high significant (p less than 0.005) rise in the prevalence of symptoms of chronic bronchitis in subjects exposed passively to smoking in the home.

[Cytological examination of the intrathoracic lymph nodes (author's transl)].

During the last few years, cytological examinations of the intrathoracic lymph nodes have become a usual method of bronchological examinations, being applied by way of routine. Taking the analysis of 3408 perbronchial and pertracheal lymph node punctions as a basis, the author discusses the results. Mostly the intrathoracic nodes of lung cancer patients were examined.

[Cytological classification of lung carcinomata (author's transl)].

By comparing the cytological examinations and the final histological classification, the author discusses the possibilities of cytological type judgement. Using a staining method invented by himself, he was able to achieve a conformity of the cytological and of the final histological classification in 80 per cent of all cases. Abstaining from the differences in the judgement of maturity, the results of both methods were in conformity even in 89 per cent of all cases.
