In a 72 year-old woman with microcytic anemia, small bowel study showed tumoral lesions. Malignant melanoma was histologically proved. Clinical and radiological aspects of metastatic malignant melanoma of the small bowel are discussed and hypothesis advanced to explain absence of an identifiable primary lesion.
IgG and IgM anticardiolipin antibodies (aCA) were studied prospectively in 20 consecutive patients (12 females, eight males, mean age 74.6 +/- 14 yr, range 62-86 yr) with giant cell temporal arteritis before and during corticosteroid therapy (days 7, 30, 90 and 180). IgG-aCA were present in 10 out of 20 cases and in nine out of 12 with positive temporal artery biopsy but were not found in 20 paired control subjects. During steroid therapy aCA levels returned to within the normal range in 60% of patients with positive aCA at day 7 and in 80% at day 30. In two cases aCA persisted during the 6-month follow-up despite clinical and biological success. No association was found between aCA and thrombotic events.
We report 9 cases of secondary carcinomas of the kidney. The primary source of cancer was found in the lungs (7 cases), in the larynx (one case) and in the pyriform sinus. Clinical or radiologic signs of these renal metastases were comparable to primary carcinomas of kidney. The mean survival outlook for these patients was 8.1 months. Radical nephrectomy was performed in five cases. In a patient previously treated for a primary carcinoma and especially for a lung carcinoma, when a solid renal mass of kidney is discovered the hypothesis of a renal metastasis must be kept in mind. Because of lack of specific feature of these tumours and because of their often poor prognosis further investigations such as percutaneous fine needle aspiration for cytopathologic study must be considered.
Inquiries were conducted to determine the prevalence of anal incontinence in a) the general population over 45 by a gallup poll studying 1,100 persons (A); b) 3,914 patients seen by their general practitioner or their gastroenterologist during the same week (B); c) 500 patients consulting for urinary stress incontinence (C1); d) 1,136 neurological patients suffering from micturation disorders (C2); and e) 10,157 elderly persons living in retirement homes or in hospital (D). In the general community (A), the prevalence of anal incontinence, including gas and stool incontinence, was 11 percent, the prevalence of fecal incontinence, 6 percent, the prevalence of daily or weekly fecal incontinence, 2 percent; prevalences were respectively 15.5 percent, 7.9 percent, and 3.2 percent in group B, and 27 percent, 9 percent and 3.8 percent in group C1. The prevalence of fecal incontinence was 18 percent in group C2 and 33 percent in group D. Prevalence did not depend on age in group A and C1, but was twofold higher in group C1 than in group A. The prevalence increased with age in groups B and D.
Modifications of inter-alpha-trypsin inhibitor (ITI) in inflammatory syndromes were determined by studying its serum components: ITI 80 (the native form) and serum derivatives (SD), as well as urinary ITI derivatives (UID) excretion in 31 controls and 128 patients with inflammatory of various origins. The patients were divided into 4 groups: Group I bacterial infections (n = 29); Group II cancers (n = 50); Group III inflammatory diseases (n = 14); Group IV inflammatory syndromes due to other causes (n = 35). Other markers of inflammation were also studied. In bacterial infections and cancers ITI 80 concentrations were significantly decreased, with values of 0.55 +/- 0.15 g/l and 0.54 +/- 0.15 g/l respectively vs 0.65 +/- 0.11 g/l in controls. SD concentrations were significantly increased in all 4 groups: Gr I: 0.31 +/- 0.12 g/l; Gr II: 0.30 +/- 0.11 g/l; Gr III: 0.25 +/- 0.08 g/l; Gr IV: 0.24 +/- 0.10 g/l, as compared with 0.16 +/- 0.09 in controls. UID excretion was increased in all cases, particularly in bacterial infections and cancers (10.8 +/- 13.4 and 6.0 +/- 8.8 mg/mmol of creatinine vs 1.5 +/- 1.7 g/mmol). A significant correlation was observed between CRP levels and SD levels. In bacterial infections and cancers, a fall in ITI associated with a rise in SD and an increase in UID excretion is suggestive of degradation of the native form. In inflammatory diseases and inflammatory syndromes of other causes, the rise in SD without significant variations in ITI 80 suggests and increase in SD synthesis. The correlation between CRP and SD seems to indicate that SD are produced in the early stage of inflammatory syndromes.

In hepatic granuloma, identification of lipogranulomas generally leads to etiological diagnosis. The case reported here was granulomatosis due to mineral oil ingestion, revealed by prolonged fever. In the literature lipogranulomas are generally asymptomatic and diagnosed at autopsy.

The authors report a case of primary osteosarcoma of the liver in a 75 year-old man with post hepatitic B cirrhosis. The hepatic tumor was discovered on ultrasound and computed tomography. Angiography showed a hypervascularized tumor. The patient died rapidly. Diagnosis of primary osteosarcoma of the liver was established through histopathological examination of post mortem specimens and was confirmed by immunohistochemical study. From this and two other previously reported cases the authors describe the different primary hepatic tumors mimicking osteosarcoma.

A case of carbimazole-induced cholestatic hepatitis is presented. A woman received carbimazole for hyperthyroidism for 3 months. Five months later, she had prompt recurrence of cholestasis parameters after rechallenge (2 days of treatment). Histologic examination showed predominantly centrilobular cholestasis. Only 5 other cases have been published in the literature. An idiosyncratic mechanism seems likely.
74 cirrhotic patients with a history of variceal or gastric bleeding were randomly assigned to treatment with propranolol (40 to 360 mg/day) or placebo. The patients were all in good condition and doses of propranolol were titrated until a 25% reduction in heart rate was achieved. After 2 years, the cumulative percentage of patients free from rebleeding was significantly greater among the patients receiving propranolol (79%) than in the placebo group (32%; p less than 0.0001). Similarly, the percentage of surviving patients was significantly greater with propranolol (90%) than with placebo (57%; p less than 0.02) after 2 years. It was concluded that in cirrhotic patients in good condition, propranolol reduced both the risk of recurrent gastrointestinal haemorrhage and the mortality rate during a 2-year period of continuous administration of the drug.
To establish if CA 19-9 could detect early pancreatic cancer, we measured its serum concentration in 866 patients admitted for benign diseases and observed for 2 years. All patients with an elevated CA 19-9 level (greater than 40 units (U)/ml) were submitted to a computed tomography (CT) scan of the pancreas. The CA 19-9 level was increased in 117 patients. One hundred fifteen of these 117 patients had false-positive elevations. The CA 19-9 concentration was elevated mostly in benign hepatobiliary diseases. In this group of patients, CA 19-9 was correlated to alkaline phosphatase values. Eleven patients showed an elevated CA 19-9 level for 10 months without any malignancy developing. One patient had a normal CA 19-9 concentration 8 months before clinical signs of pancreatic carcinoma developed. We conclude that CA 19-9 measurement is of no value for the early detection of this malignancy.
Among the 931 patients who were admitted, over a 9-month period, to an internal medicine department, a group of 84 patients (9 p. 100) whose erythrocyte sedimentation rate (ESR) was 70 mm or more at 1 hour was selected and compared to the remaining 847 patients whose ESR was below 70 mm at 1 hour. In most cases, a pathology likely to account for the distinct rise observed in ESR was found (infection in 42 p. 100 of the cases, malignant disease in 27 p. 100, inflammation in 20 p. 100), and only 5 p. 100 of these rises remained unexplained. This makes an ESR of 70 mm or more a good index of morbidity generally, without pointing at any specific disease. An ESR of 70 mm or more has very low sensitivity (always below 30 p. 100), so that no disease whatsoever can be excluded when the ESR is only slightly elevated. Moreover, in all but infectious diseases a distinctly high ESR is not an index of severity.
The repercussions of food intake on blood pressure may account for certain malaises which occur after meals in elderly people. In this study, blood pressure and heart rate were measured during and after a meal in 39 elderly hospital patients divided into two groups depending on whether or not they were taking drugs likely to act on arterial blood pressure. The patients were compared with two groups of controls: 29 young adults examined after a meal and 16 elderly subjects examined at a distance from meals. A significant fall in blood pressure starting 18 minutes after the meal and without concomitant increase in heart rate, was observed in the 2 groups of elderly patients. No significant changes in blood pressure and heart rate were observed in the 2 control groups. In elderly people, food intake might act on blood pressure through entrapment of blood in splanchnic territories and/or through alteration of baroreceptors.
