[Evaluation of pulmonary arterial hypertension by Doppler echocardiography in chronic respiratory insufficiency].

The usefulness of doppler-echocardiography for the assessment of pulmonary arterial hypertension in patients with chronic respiratory failure was evaluated in 24 consecutive patients with chronic obstructive lung disease. Seventeen of these 24 patients (71 p. 100) who had tricuspid valve regurgitation analysable by the continuous wave doppler technique were selected as study group; they included 15 men and 2 women aged from 33 to 78 years (mean 63 years).

[Brushings and bronchial biopsies in small-cell cancer. Comparison of results].

The typing of bronchial carcinoma is important for therapeutic decisions and may be made on bronchial brushings. Sixty six small cell and poorly differentiated squamous cancers were studied. Our personal method of preparing brushing is suggested.

[Legionnaires' disease with late pulmonary sequelae. Apropos of a case].

The authors report a case of legionnaires' disease with retractile late sequelae affecting the lingula and the dorsal segment of the culmen. They stress the need for appropriate and prolonged treatment because of the possible presence of intracellular Legionella pneumophila. The existence of an associated staphylococcal infection is also one of the hypotheses raised in explaining such sequelae.
