[A pleuropulmonary tuberculosis study in a pneumology service].

We reviewed the records of 125 patients admitted in our Service of Pneumology from January 1985 to December 1992, which were diagnosed of pleural or pulmonary tuberculosis. Several characteristics are described, with the following findings: 1) Higher incidence among men. 2) Relevant incidence among young people. 3) Frequent association with risk factors or concomitant diseases, mainly tobacco and alcohol consumption. 4) Delay in the diagnosis, probably due to the unspecific symptoms observed; fever, cough, constitutional syndrome. 5) The must frequent radiological findings were pleural leakage and cavitated infiltrations affecting the upper lobes. 6) Sputum microbiological exam still has a high diagnostic profitability.

[Mediastinal leiomyosarcoma].

Primary mediastinal leiomyosarcomas are malignant sarcomas with unknown etiology not deriving from the smooth muscle fiber of the esophagus, trachea or main vessels. Very few cases have been reported in the literature and, although they are clinically unspecific, their histology is unique. The case described here is a 66-year-old woman with a leiomyosarcoma localized at the medium and posterior mediastinum, clinically presented as a mediastinal emergency.

[Kartagener's syndrome with normal ciliary ultrastructure].

We present a case of a man with Kartagener's syndrome (KS) (situs inversus, sinusitis and bronchiectasias) and with clinical signs of respiratory infection. An electronic microscopy study was conducted, showing a normal bronchial cilium. Although, traditionally, KS has been associated to ultrastructural abnormalities of the cilium, some cases similar to ours have been described, suggesting the presence of functional ciliary disorders in absence of ultrastructural defects.
