[Epidemiology of Legionnaires' disease].

The authors discuss the epidemiological problems of legionnaire's disease. Although Legionella is known to proliferate in watery environments, the origin and extension of sporadic cases and the factors responsible for bacterial spread remain unclear. The problem of prevention has also to be resolved.

[Circulating immune complexes and bronchopulmonary cancers].

This study of circulating immune complexes was carried out using a C1q radio-labelled complement fixation test in 162 patients suffering from broncho-pulmonary disease. There were a similar number of positive results in primary cancer (44%) or secondary (53%) in tuberculosis (37%) or other pathologies (64%). With primary causes neither the histological type nor the stage of extension were associated with any particular frequency of positive tests. The diagnostic interest of research into circulating immune complexes thus appears limited. This study shows however, the activation of humoral systems of immunity during the course of broncho-pulmonary diseases, and raises the prospect of qualitative studies into the nature of the antigen implicated and their role in the mechanism of defence of the organism.

[Pulmonary silicosis (not including asbestosis and berylliosis].

The pleuro-pulmonary pathology of asbestos, top most of silicates, is today well known. Other silicates, talcum powder, clays, micas essentially, are exploited and commercialized. Their pathology is less well known and often contradictory because of the heterogeneity of the inhaled minerals. All can contain large quantities of quartz and some varieties of talcum and a considerable proportion of asbestos fibres. These minerals can provoke severe pneumoconioses, silicoses and asbestoses respectively. Some relatively pure products do not contain these contaminants. In case of intense and prolonged dust inhaling, they can produced an impressive pneumoconiosis with relatively mild clinical signs as shown by the series of 27 cases of pneumoconiosis from the french talcum powder as reported by the authors. The chemical nature and electronic structure of different silicates are very similar. It raises the question of the noxious effect of asbestos and the relative innocuousness of other minerals of the same family, and wether the fibrous structure alone is implicated.

[Posttraumatic real and false Mendelson's syndromes].

Six observations of post-traumatic acute respiratory insufficiency of alveolar origin are reported briefly. Three of them have been attributed to a Mendelson's syndrome. This authors showed that diagnosing these lung diseases by acid inhalation is particularly difficult in casualties. It is a diagnosis by elimination which no certainty can prop. These post-traumatic Mendelson's syndrome are serious and difficult to prevent. In the three cases reported two accidents occurred during or immediately after an intubation. The systematic use of an efficient anti-acid could be recommended in all serious casualities.
