Women 63-between 1949 and 1970 has shown 11 K. A., 1 Bowen's diseas of the vulva, a carcinoma of the rectum (together with a carcinoma of the anus). This last association allows to integrate this observation to Torre's syndrome. No return of the K. A. since the removal of the carcinomas (1970) which have not actually come out again.
Eleven patients with primary hyperparathyroidism confirmed by histologic examination were subjected to a comparative study of the results of quantitative determination of parathormone and of quantitative bone biopsy. Quantitative radioimmunologic determination of parathormone was carried out with the aid of an N-terminal specific anti serum, while the histologic features studied were the periosteocytic and osteoclastic absorption surfaces. On the basis of a combination of the results of these two techniques, the diagnosis could be made in all the cases studied. A statistically significant correlation was observed between the results of quantitative determination of parathormone and those of histologic examination of the surfaces of periosteocytic lacunae (r = 0.63; p = 0.05).
The authors report 7 new cases of colitis above a carcinoma. The study of these cases and of those reported in the literature shows the main pathological characteristics of the lesions and permits discussion of the pathogenesis. Chronic ischemia caused by an increase in intraluminal pressure above the neoplastic stenosis seems to be the main etiological factor.

The authors report here a case of antral hemorrhagic gastritis without ulceration nor erosion, but with intravascular coagulation within the chorionic layer, which had a prolonged course in a patient with non-alcoholic cirrhosis, and which continued in spite of surgical cure of portal hypertension. The authors discuss various theories which might explain this hemorrhage and the development of localised intravascular coagulation, together with its relationship with the cirrhosis.
Coxopathies with rapid chondrolysis: Comparison of clinical and anatomical findings. Clinical, radiological, laboratory, and antomical data concerning 14 coxopathies with rapid chodrolysis are presented with reference to 12 patients aged from 37 to 77 years. Three criteria define this affection: reduction of the joint space by at least 50 per cent, in one year or less; chondrolysis completed in 1 to 3 years; complete narrowing in the superior part of the joint; isolated narrowing, exceptionally with a discrete osteophytosis. The pain rapidly becomes very severe. Such symptoms are, at first, indicative of coxitis, but the establishment of a radio-clinical picture of coxopathy rapid chrondrolysis is more indicative of an arthrosic origin. This could represent a particular evolutive stage of coxarthrosis related to the initial chondrolytic phase of rapid destructive coxarthrosis. From an early stage, the anatomical facts indicate an association between the degenerative lesions and the non-specific inflammatory lesions of the synovial membrane. These facts are interpreted, on the basis of data in the literature, as an indication of synovial lesions caused by the liberation of osteocartilaginous fragments. The problem of the pathogenesis of this rapid chondrolysis is then discussed.
