[Effects on the bone metabolism of long-term treatment with antivitamins K1].

Oral anticoagulants (OC) prevent the activation by carboxylation of coagulation proteins. However this action also affects osteocalcin, or bone Gla-protein, a parameter of bone remodelling. Phosphorus and calcium metabolism, osteocalcin levels and bone mineral content were studied in twelve men aged under 60, and who had been taking OC for more than a year, in comparison with a paired group of nine controls with the same cardiovascular pathology but not taking anticoagulants. Osteocalcin levels were lower in the OC group (3.44 ng/ml) than in the control group (5.88 ng/ml) (p = 0.01). There was no significant difference in other phosphorus/calcium balance parameters nor in bone density between the two groups. No evidence was found of any osteopathy in the OC group, but the decrease in serum osteocalcin could result either from inhibition of its secretion or of its carboxylation, or from an action on the osteoblast.

[Myocardial infarction in patients aged 70 years and over].

109 subjects aged 70 years (58 women, 51 men; average age 77 years) were hospitalized in the CICU (Cardiology Intensive Care Unit) over the period stretching from 1984 to 1986. The average length of stay in the CICU was 1 week, completed by an average stay of 5 days in the cardiology department. 100 per cent of the patients were followed up. Of the clinical parameters made evident by this study, the authors note that hypertension was the predominant risk factor (52.2 per cent); a history of coronary disease was noted in 60.5 per cent; 26.6 per cent of the patients were hospitalized before the 6th hour, chest pain being typical in 78 per cent versus painless in 11 per cent of patients; topographically, the infarction was anterior in 55 per cent, posterior in 40.4 per cent, and around the circumference in 4.6 per cent of cases; 80.8 per cent of the infarctions were transmural versus 19.2 per cent of infarctions without the Q wave--the latter accounted for a higher hospital mortality rate (38 per cent versus 27.3 per cent). The main complications were disturbances in rhythm (60.6 per cent) and LVI (56.9 per cent). Complications on the form of infections were noted in 15.6 per cent. Apart from the usual indicators of severity (cardiogenic shock, VF, LVI), infarction of the RV and AF had a serious effect on the prognosis. latrogenic disease accounted for 18.9 per cent. From the point of view of prognosis, hospital mortality was 30 per cent; mortality after one year was 44 per cent and 47.7 per cent after 2 years (in a group of 76 subjects).(ABSTRACT TRUNCATED AT 250 WORDS)

[Acute non-obstructive necrotizing enterocolitis in adults].

Acute non-obstructive necrotizing enterocolitis in adults is characterized by pathological features: it is an intestinal necrosis beginning in the mucosa, without obstruction of the mesenteric vessels. The disease occurs in a variety of circumstances which may be roughly divided into infections and fall in proximal or distal mesenteric flow rate, the infectious and circulatory mechanisms often coexisting. Little information on the diagnosis is provided by clinical and paraclinical data. Management is medical and/or surgical; it includes alleviation of the symptoms in intensive care unit, attempts at producing local vasodilation whenever possible and resection of the intestinal segment affected. In many cases the diagnosis is made at exploratory laparotomy. The prognosis is poor; it depends on the patient's age, on the extent of the lesions which sometimes require wide intestinal resections, and on the time to diagnosis.
