[Domiciliary assisted respiration in the Languedoc-Roussillon region (author's transl)].

The activities of the Society for Domiciliary Assisted Respiration founded in the Languedoc-Roussillon region in 1973 are reported. Up to September 30, 1976, 281 patients were treated, 189 are still alive. Obstructive chronic bronchopneumopathies were predominant. In the second place were restrictive respiratory insufficiences and respiratory muscle failure in the third. Obviously, careful attention by a specially trained doctor and nurse must be guaranteed, as well as technical support. Blood gas analyses and spirographic investigations control the course of treatment. Domiciliary assisted respiration not only prolongs the life of numerous patients, but also improves its quality.

[Bronchial mucociliary clearance in chronic bronchitics (author's transl)].

Bronchial mucociliary clearance is analysed in 13 clinically stable patients with chronic bronchitis in comparison with 7 normal non smokers by measuring the rate of removal of inhaled monodispersed particles of resin (diameter: 8.1 +/- 3.5 micrometer) tagged with 99mTc. Particles delivered with a high insufflation rate are uniformly deposited on proximal airways. The pattern of distribution is comparable in all the subjects studied. In normal non smokers, the percentage of bronchial radioactivity cleared 1 h after the inhalation was 34 +/- 11.2 percent. The patients may be divided into 2 groups: Group 1 (n = 6) is characterized by a mucociliary clearance similar to the normals while group 2 (n = 7) shows a low mucociliary transport rate (decrease of bronchial radioactivity after 4 h less than 10 percent).

[Trehalose, the principle disaccharide of wine].

By gas chromatography of trimethylsilylated derivatives of sugars, trehalose has been shown to be the main disaccharide in wines; its amount can reach 600 mg/l. Other disaccharides identified (sucrose, isomaltose, lactose and turanose) are present in small amounts, seldom above 50 mg/l, sometimes below 5 mg/l. Traces of melibiose and gentiobiose are possible. Conditions of trehalose formation by yeast during fermentation are described. Also technological applications of these results are discussed.

[Granulopenia of infectious origin].

Among the various infectious and parasitic disease liable to produce granulopenia, the authors selected certain diseases which represented their personal experience. Classically, leukopenia may occur during typhoid fever, but was not present in all of the series of 114 adults they observed with this disease. It only occurs after antibiotic treatment (Thiamphenicol in the majority of cases). During acute brucellosis (188 cases studied) granulopenia was constant. It occurs early and is lasting. It reappears during septicemic relapse. Leukopenia is corrected during treatment by tetracycline antibiotics. Neutropenia during disease is frequent but usually labile. This characteristic explains why there was no granulopenia in 90 cases of mumps and 64 cases of chickenpox. Finally, during Kala Azar, 8 cases confirmed certain already well known data: the considerable reduction in granulocytes but also anemia and thrombocytopenia.

[Treatment of congenital dislocation of the hip by Salter's innominate osteotomy. Study of the first 40 cases operated on at the Orthopedic Institute, Kassar Said, Tunisia].

1) Twenty-nine children aged 18 months to 7 years with 40 congenitally dislocated hips, were treated between 1964 and 1971. Six hips had a closed reduction, 34 had an open reduction and capsulorrhaphy, and all had an innominate osteotomy. 2) Complications of the treatment included 2 joint infections. Of 11 hips which were unstable post-operatively, more than half were due to errors of the operative technique, and 8 required further surgery. Avascular necrosis of the femoral head occured in 3 hips post-operatively, and another 3 showed irregular ossification of the femoral epiphysis. All 6 hips had had an open reduction, and were mainly in older children who had inadequate pre-operative traction. 18 hips were stiff post-operatively ; 17 had had an open reduction ; Seven of eleven were improved by traction and physiotherapy. 3) The average length of follow-up was 4 years. Although only 70 p. 100 of the hips were clinically satisfactory, 92 p. 100 had excellent or good anatomical results as seen on radiographs.

[Pulmonary edemas of infectious origin].

Diffuse pulmonary edema, capable of arising in the absence of hemodynamic disorders is rare in infectious disease. They take on two different clinical appearances: a) acute edema of the lung with the syndrome of asphysia, b) a subacute dyspneic pneumonia with hypoxemia and hypo or normocapnia. These initial disorders can be followed by progressive respiratory failure secondary to the development of diffuse interstitial lesions with fibrosis and intra-alveolar hyaline deposits. The bronchiolo-alveolar lesions which induce a fibrin rich exudate are directly caused by the patogenic agent: myxovirus, essentially influenzae, and more rarely adeno or herpes virus. The role of bacteria and of certain parasites is more debateable.
