[Value of superior vena cava angiography in Schwartz-Bartter syndrome (author's transl)].

Schwartz-Bartter syndrome often results from lung cancer. With reference to two observations, attention is drawn to the value of opacifying the superior vena cava for demonstrating the tumor. This investigation also allows guided biopsy sampling as exemplified in the second observation. Vascular investigations seem all the more useful as small-cell carcinoma often develops outside the bronchi and are often inaccessible by endoscopy.

[External retromalleolar lymphography of the superficial and deep lymphatics of the lower limb (author's transl)].

External retromalleolar lymphography was employed to explore lower limb lymphatics in 39 patients. Though this type of approach enables deep lymph vessels of the thigh to be studied--at the price of a more difficult catheterization than when the classical approach is used--it is ineffective for demonstrating deep lower leg lymph vessels, filling occurring only in the superficial network. Its indications are therefore limited to cases following unsuccessful attempts with the classical approach.

[Therapeutic embolization for traumatic renal haemorrhage. 11 cases (author's transl)].

Therapeutic embolization by means of autologous clots or fragments of gelatin sponge was carried out in 11 patients suffering from renal haemorrhage of traumatic origin (5 needle biopsies, 3 surgical operations, 2 external traumas, 1 penetrating wound). Arterio-venous fistulae were present in 6 cases and arterial lesions in 5. Performed with a fine catheter, embolization was highly selective for the segmental arteries involved. The clinical symptoms disappeared within less than 12 hours in three patients, within 2 to 4 days in five and within 15 days in one. In two patients haematuria was only temporarily arrested ; a second embolization could be performed in one of these, but nephrectomy was required in the other.

[Angiographic exploration of a case of a case of adrenal APUD adenoma secreting three hormones: VIP, catecholamines, and somatostatin (author's transl)].

An APUD adenoma of the right adrenal was discovered in an adult after angiography and compted tomography The tumor had provoked a WDHH syndrome. Selective venous sampling before operation demostrated the presence in the tumor of hormonal secretions (VIP and catecholamines). The patient recovered after excision of the tumor, which contained large quantities of intracellular somatostatin and VIP.

[Air in the small intestine in adults: results of a study in a control group of 827 subjects (author's transl)].

Fairly small amounts of air (usually one loop visible) were found in the small intestine of 41,2 plus or minus 3,4 p. cent (at the 95 p. cent confidence level) of a series of 827 adults (553 inpatients and 274 outpatients). Air in the small intestine was noted more frequently in the hospitalized patients (45,2 plus or minus 4,1 p. cent) than in the outpatients (33,2 plus or minus 5,6 p. cent) (p. less than 0,001). This study confirms the hypothesis, contrary to conventional data, that the presence of air in the small intestine occurs sufficiently frequently for it not to be considered pathological. Air is more frequently visible in the proximal jejunum (48,4 p. cent) than in the ileum (27,3 p. cent), and is noted in the umbilical region, the transition zone, in 24,3 p. cent of cases. The mean diameter of th proximal jejunal loops is 25,6 mm (standard deviation 3,7 mm). The thickness of the proximal jejunal folds varies between 1 and 2 mm, the interfold thickness being 3 to 6 mm. The thickness of the small intestine wall (measured in the interfold space) is less than 1,5 mm. These figures relate to direct measurement of radiographic images, without correction due to enlargement.

[Multiple spleens without obvious cardiac abnormalities. Results of highly selective arteriography in one case (author's transl)].

Multiple spleens were first discovered accidentally during abdominal arteriography and were then investigated by selective and highly selective injections. The vascularization of the small spleens was by means of a branch of a main coeliomesenteric artery, which appears to be a constant feature in this syndrome, and possibly by an accessory artery arising directly from the aorta.

[An error in the determination of the bi-ischial diameter by the Thoms grid (author's transl)].

After recalling the principles of homothetics which are the basis of radiological pelvimetry by the Thoms method, the authors carry out a study of the pelvimetry accessory presently the most distributed in France. It turns out that the grid introduces an error that, depending upon the conditions under which it is used, can reach levels of 4% underestimation. This error of 4% of something that itself is merely a calculation has little impact since it only affects 8% of the results.

[Use of a microprocessor for pelvimetry (author's transl)].

Calculating machines have made the use of Thoms grid unnecessary, and have many advantages: the exact measurements of the different diameters can be obtained, and it is now possible to establish a more precise prognosis by introducing supplementary data such as those obtained by ultrasonography.

Correlation between lymphographic grouping and anatomic and clinical stages in chronic lymphoid leukemia.

In a retrospective study of lymphograms in 55 patients with chronic lymphatic leukemia observed 42-170 months, four lymphographic groups were established according to lymph node size and morphology. In group 1, the lymph nodes were only slightly enlarged and pathologic in appearance. In group 2, the nodes were moderately enlarged and appeared reticular. In groups 3 and 4 the nodes were greatly enlarged and appeared foamy, striated, or "ghostlike" (similar to those seen in lymphoma). The correlation between the lymphographic groups and a new clinical classification (stages O-IV), which has been demonstrated to have prognostic values, was statistically significant: clinical stage O and lymphographic group 1; clinical stages III and IV and lymphographic groups 2, 3, or 4. Clinical stages 1 and II were dispersed throughout the different lymphographic groups. Although the specific prognostic value of the results of lymphography is not apparent in clinical stages O-II, it does seem to be established in stages III and IV. In these stages, the number of deaths was significantly greater in patients in lymphographic groups 3 and 4 when compared with those in lymphographic group 2.
