[Streptococci isolated from the blood after tooth extraction. Their role in subacute bacterial endocarditis]. / Etude des streptocoques isolés dans le sang après extractions dentaires. Leur rôle dans l'endocardite bactérienne subaiguë.

A classification, according to the Lancefield's method, of the streptocoques isolated in the blood, after teeth extractions, as well as a determination of their sensibility to the antibiotics, are attempted in this study. It concerns to 23 adults, well supported, to whom multiple extractions, under general anesthesia have been done. We studied both biochemical and serological reactions, and a test for the antibiotic resistance is realised. We insiste in the contrindiction of streptomycine and sulfanilamides in the treatment or the prevention of bacteremia of dental origine.

[Prognostic significance of immunologic tests in cancer of the oral cavity]. / Valeur pronostique des tests immunitaires dans les cancers de la cavité buccale.

An analysis of delayed action cell immunology tests involved 300 patients suffering from stomatological cancers. The tests used, tuberculine, candidine, varidase and DNCB have no particular value as far as discovering the size of the tumour, the quality of eradicating treatment or its progress. On the other hand, bias in the same direction and, even more, variations in the direction of immunity in the course of evolution seem to be a reflection of the patient's immune defence potential. This immune defence potential which can be roughly assessed in this way dose not seem to be reduced by chemotherapy or increased by immunotherapy, at least judging by the criteria used.
