[Asymptomatic pulmonary embolism and venous thrombosis of the lower limbs. Study with spiral x-ray computed tomography].

Aim: Spiral Computed Tomography (CT) allows diagnosis and follow-up in pulmonary embolism (PE).

Material And Method: We studied prospectively with spiral CT 21 patients to evaluate the frequency and the extent of asymptomatic PE in the patients with lower limbs venous thrombosis and no pulmonary symptomatology.

Results: We observed a asymptomatic PE in 8/21 cases (34%).

[Intestinal intussusception in adults: contribution of ultrasonography].

After observing a benign tumour of the small bowel which led to ileo-ileal invagination in an adult we recalled the main data on the epidemiology, aetiology and diagnosis. In infants, the diagnosis is usually made but in adults, the situation is much rarer and the clinical and radiographic signs are not specific. Echotomography of the abdomen is the most reliable examination.

Measurements of the normal lumbar spinal canal by computed tomography. Segmental study of L3-L4 and L4-L5 related to the height of the subject.

Computed tomography measurements of the main diameters and cross section areas of the lumbar vertebral canal and the lower end of the dural sac at the L3-L4 and L4-L5 levels were made in 34 young male adults who were free of symptoms. This study shows a statistically significant correlation between the height of the subject and the cross sectional area of the canal and the dural sac, and the interpedicular diameter. The determination of regression coefficients enabled an estimate to be made of the mean values of these parameters in relation to height, the actual values having a normal distribution around these means.

[South American furunculoid myasis. (Report on a case) (author's transl)].

The authors report on a case of Dermatobia hominis South American furunculoid myasis, observed in a patient back from French Guyana. Spontaneous expulsion was obtained in 72 hours by both local irrigation with xylocain 2 p. 100 and internal treatment with thiabendazol.
