Report of an anatomical-clinical study concerning 173 patients with an average follow-up period of 5 and 1/2 years after the onset of myocardial infarction. They were subdivided into four comparable groups differing only in the quality of the long-term antivitamin K treatment which was administered. A survey of the coronary artery and myocardial lesions was performed for every heart. Acute occlusive coronary artery thromboses were four times less frequent in the correctly treated group then in the other three groups (p less than 0.001). There was no significant difference between the insufficiently treated groups and the untreated group. Recurrent myocardial infarctions were accompanied in 90 per cent of cases by acute occlusive coronary artery thromboses and were four times less frequent when treatment was efficient (p less than 0.001). These results confirm the part played by coronary artery thrombosis in the aggravation of coronary atherosclerosis and justify the attempts at long-term prophylaxis. The provide the proof that antivitamin K administration, at efficient dosage, maintained for a long time, has a significant influence on the cause of death in these patients, by decreasing the number of coronary artery thrombosis. Long-term anticoagulant treatment, in spite of its haemorrhagic complications and limits, should not be given up until a new efficient treatment is available.

[Angiofollicular lymphoid hyperplasia (Castelman's tumor) in the mediastinum. Apropos of 2 cases].

The authors report two new cases of angiofollicular hyperplasia of the mediastinum (Castelman's tumour). The only clinical peculiarity was a rapid increase in volume. The authors then review about 200 published cases. Emphasising the existence of 3 different histological types (plasma cell form, vascular hyaline form and intermediate form) and on the association in certain cases of hematological disorders such as anemia and hypergamma globulinemia. The significance of this lesion is discussed. An inflammatory theory with reactional hyperplasia of the beta-lymphocytes is proposed. It was supported by a direct immunofluorescent study of two cases (first study of this type carried out on such lesions) which showed polyclonal plasma cell hyperplasia predominating on the IgG.

[Bronchopulmonary adenocarcinomas of apparently primary origin. A retrospective study of sixty-six patients (author's transl)].

A retrospective study of sixty-six case-reports confirmed the traditional factors described in this histological type of cancer, particularly the age, a slight predominence of males, and the very poor prognosis. A selection was made of 42 cases in which extensive investigations had been carried out to search for a possible extrapulmonary primary adenocarcinoma, but only one case of renal cancer and one of thyroid cancer were demonstrated. Autopsy had revealed the presence of 3 prostatic lesions and their relation to the pulmonary affection is discussed. Thyroid cancer had been found in 2 cases, which emphasizes the value of scintigraphy for this organ, whereas the authors felt that other investigations were of no value in the absence of clinically oriented signs.

[Sarcoidosis associated with tuberculosis. A study of seven patients (author's transl)].

The authors studied seven patients with sarcoidosis and tuberculosis: the affections co-existed in 3 cases but were separated by varying intervals of time in the 4 other patients. They discuss the diagnostic, therapeutic, and nosological problems posed by these cases, and review the various hypotheses that have been suggested to explain these associations in relation to the pathogenesis of the sarcoidosis.

[Value of quantitative evaluation of bacterial species in bronchitic infections (author's transl)].

A quantitative evaluation of the bacterial species in the sputum collected from 93 patients was conducted over a period of 7 months. The patients were divided into five different pathological categories, while separating those patients who had not received antibiotic therapy before samples were taken from those who had been administered this type of treatment. Samples were repeated after one week in 30 cases. The most frequently encountered germs were hemophilus (10(6)) and pneumococcus (10(7)). In simple bronchopathies, Gram-negative germs were only isolated at levels of 10(5) from patients previously treated with antibiotics, which demonstrates their low pathogenic role. In most severe bronchopathies they were isolated more frequently, but at levels which rarely exceeded 10(6). Their pathogenic role has to be evaluated as a function of the progression in clinical signs. The authors underline the frequency with which pneumococcal strains are resistant to tetracyclines.
