[Rapid 105 mm ampliphotography (author's transl)].

The authors report the results obtained with a new 105 mm ampliphotographic camera for filming at high speeds (camera GV 105 of the General Radiological Company). Thanks to a rate of 8 films per second, this camera seems particularly interesting for the study of sphincters and fleeting phenomena. However, the quality of the images, comparable with those of standard films, the rapidity of the examinations, the easy reading of the films, the important reduction in the dose of X Rays delivered and the economy of film, render advisable the use of this technique in general radiology. Unfortunately, there is not at present a simple, rapid formula for presentation of the films obtained. Progress will also have to be made in order to facilitate loading of the camera. Rapid resolution of these problems will permit this technique to be more widely used.

[Dodger filters in the modulation of X-Ray beams (author's transl)].

Dodger filters represent a very great improvement in the usual technique of modulation of X-Ray beams, The mobility of the filters permits one to use them efficaciously in numerous situations encountered in common radiodiagnosis. Original optical methods ensure perfect adaptability of the filters to morphology and density of the structures examined. The shape and structure of the filters prevent formation of artefacts ducts mains interference on the X-Rays. To an improvement in the quality of the films, may be adder reduction in exposure of the examined subjects. This apparatus, easy to bring into operation, may thus be used more widely in numerous branches of radiodiagnosis, in particular, in cerebral and visceral angiography.

[Granulocytic sarcoma (chloroma) of small bowel: an unfrequent cause of intestinal obstruction].

Granulocytic sarcoma or chloroma is a malignant extra medullar tumor, based on inmature myeloid cells. It usually emerges as a secondary manifestation of acute myeloid leukemia. Chloromas are scarcely diagnosed in patiens without hematological malignances, either peripheral or medullar, and are thus frequently misdiagnosed for other tumors. In these patients, further development of acute leukemia seems to stand as a rule. Small bowel location of these tumors has hardly been reported. A case of granulocytic sarcoma in a non-leukemic at time of diagnosis patient is reported therein. Medical literature is briefly reviewed.
