[Comparative study of 3 therapeutic methods for Pouteau Colles' fracture. Apropos of 97 cases].

Results of three therapeutic modalities used for the treatment of a homogeneous series of patients with a Pouteau Colles fracture are analyzed. Orthopedic treatment provided deceiving results. Pinning was, on the contrary, very effective, intrafocal pinning with immediate mobilization of the wrist appearing perfectly effective. Few complications were reported in contrast to plastered immobilizations. Good results were obtained in 80% of cases and functional recovery was rapid, indicating that this method represents undoubted progress when compared with conventional therapies.

[Kirner's deformity. Apropos of 3 new cases. Review of the literature].

Three cases of Kirner's deformity in siblings are reported. Kirner's deformity consists in a palmar bending of the terminal phalanx of the 5th finger. The deformity is usually bilateral; the condition is congenital but the deformity is recognized in later childhood and has to be classified as osteochondrodysplasia.

[Latarjet's operation in recurrent antero-internal luxation of the shoulder].

Latarjet's operations as single therapy was performed in 52 patients admitted since 1976 with recurrent antero-internal dislocation of shoulder. There were no recurrences but three patients (6%) complained of residual instability. Effectiveness of results depends on use of a perfect technique : the bony ridge playing both an active and passive role should be level with the antero-internal border of the glenoid.

[Osteoid osteoma of the toes. Apropos of 2 cases].

Two patients presented with osteoid osteomas of the distal phalanx of a toe. A review of documented cases provided data on the characteristic features of these lesions. Diagnosis and treatment, in all cases, were ensured by excision biopsy, enabling a permanent cure to be obtained with a minimum of mutilation.

[Comparative evaluation of the use of glucose and fructose by the oxidative pathway in a strain of Rhizobium meliloti].

The oxidation rate in resting cells of Rhizobium meliloti was investigated with either glucose or fructose as substrate. Fructose uptake was found to be complete, whereas glucose uptake did not fully occur, yielding 2-kitogluconic acid in the medium. At the end of fructose oxidation, significant levels of this substrate and its derivatives had accumulated in the bacteria.

[Demonstration of a metabolic property of Rhibozium meliloti usable for its classification].

Fast-growing Rhizobium and Agrobacterium strans were studied for their behaviour towards two carbohydrates (glucose and fructose) according to the following criteria: acidification and soluble exopolysaccharide production by resting cells. R. meliloti and Agrobacterium spp. showed a similar behaviour: in glucose-containing medium, acidification occurred and few exopolysaccharides were produced, whereas in medium supplemented with fructose, a neutral pH was maintained and large amounts of exopolysaccharides were synthesized. Other fast-growing Rhizobium spp. did not acidify these media and produced variable amounts of exopolysacchrides.

[Biochemical variations of West African snake venoms].

Electrophoretic patterns of Bitis gabonica, Bitis nasicornis, Bitis arietans venoms have shown specific and individual variations; neither physiological nor seasonal differences were noticed. Immunoelectrophoretic study of Naja melanoleuca and Naja nigricollis individual venoms revealed a variation in neurotoxin concentration from one venom to another. Deletion of some minor fractions is noticed in few venoms. The authors think it of major interest to work on individual venoms.
