[Dilution hyponatremia and conserved natriuresis in pulmonary tuberculosis (author's transl)].

Association of dilution hyponatremia and normal natriuresis produce an inappropriate secretion of antidiuretic hormone. In this pulmonary tuberculosis case we report manifestations along with the other biological criteria of inappropriate secretion of antidiuretic hormone. All disturbances cease when pulmonary tuberculosis is cured.

[Endobronchial Abrikosov's tumor. Two new cases associated to malignant tumors].

Endobronchial localizations of the granular cell tumours or Abrikossoff's tumour are very rare (6%) but their association with malignant tumours is exceptional and perhaps fortuitous. The clinical manifestations are generally the consequence of bronchial erosion and blocking. Bronchial endoscopy is the essential examination which allows the tumour to be seen and a biopsy to be made.

[Value of isotope study with ytterbium-169 citrate in the diagnosis of pulmonary opacities of cancerous nature].

Out of 60 observations, the authors deduct the value of the isotopic study with Ytterbium169 citrate in the diagnosis of cancerous pulmonary opacities. Ytterbium169 is a radiolanthanide with a period of 32 days. Patients receive intravenously 500 muCi of Ytterbium169 citrate.
