Vanadium in depressive states.

Serum vanadium levels have been measured by neutron activation analysis. They are higher (3.10 +/- 1.38 ng/mL) in patients suffering depressive illness than in normal subjects (0.67 +/- 0.32 ng/mL).

[Normolipemic plane xanthomas and IgGk myeloma with anti-lipoprotein activity. Apropos of a case. Review of the literature].

Clinicopathologic findings are reported of a woman with plane xanthomatosis, multiple myeloma (IgG kappa) and normolipemia. Plasma lipoproteins were bound to the monoclonal immunoglobulin. The complex was separated by ultracentrifugation, then the proteins were measured by radial immunodiffusion and laser immunonephelometry. Monoclonal IgG kappa interact with the low-density lipoproteins. The literature about the association between normolipemic or hyperlipemic xanthomatosis and myeloma was reviewed and the physiopathology of this association discussed. Several hypotheses are suggested but, at present, it is shown that lipoprotein-paraprotein complexing in some patients may be due to autoantibody activity of the myeloma protein against serum lipoprotein; immune complexes interfere with normal lipoprotein catabolism resulting in xanthomas and normolipemia or hyperlipemia.

[Arrhythmia in relation to acute alcoholic intoxication in the absence of obvious cardiopathy].

Following acute intoxication with alcohol, 8 patients developed 16 episodes of arrhythmia, including 15 supraventricular tachycardias and one torsade de pointe. Seven of the 8 patients were chronically abusing of alcoholic drinks. None of the patients had clinically obvious cardiac pathology nor echocardiographic evidence of myocardiopathy. In 7 of them, however, baseline electrocardiograms disclosed disorders of intra-atrial conduction. The role of the different factors which might determine the occurrence of arrhythmia (notably alcohol, the autonomic nervous system, associated metabolic abnormalities and absorption of medicines) is discussed.

[Arsenism: a case-report (author's transl)].

Among the multiple clinical features encountered in arsenism the most striking are hematological (leucopenia, macrocytic anemia), neurological, digestive, and cardiovascular. Diagnostic rests on the assay of the arsenic content of hair and urine. D-penicillamine appears to be the best therapy. However, late development of cancer of the skin or of internal organs remains possible. The authors report a case of arsenism and review the aspects of this rare disease.

[Left ventricular aneurysms. Hemodynamic studies and surgical results].

The cardiac function of 37 cases of ventricular dyskinesia were studied by cineangiography. The amplitude and speed of contraction of the contracting parts was evaluated as well as the volume of the akinetic zone. A score of coronary artery obstruction was made for those patients who underwent coronary arteriography. All the patients had resection of their aneurysm. Four patients died in the immediate post-operative period. Six patients developed a temporary low output state requiring circulatory assistance. Twenty-seven patients were operated on successfully without posing any haemodynamic problem. Good immediate and late post-operative results were associated with an ejection fraction of the contracting part greated than 0,40, a dyskinetic area less than 40% and a coronary artery obstruction index of less than 6. Resection of the aneurysm, sometimes associated with aorto-coronary bypass grafting (5 cases), led to a marked improvement in heart failure and/or disappearance of ventricular arrhythmias.

[The fate of patients with stenosis of the trunk of the left coronary artery].

We have studied the fate of 49 patients with stenosis of the trunk of the left coronary artery of more than 50%. The follow-up period extends from 1,5 years to 5 years (with a mean of 33.83 +/- 13.55 months). The clinical picture was not characteristic. Unstable angina was found in 59% of cases. The exercice test (29 patients) was positive in 100%, with a mean depression of 3.3 mm. Stenosis of the trunk, which is rarely an isolated condition (8% of cases), is usually associated with disorders of the other main coronary vessels. Twenty six patients underwent surgery. Thirteen patients who were operable were treated medically. The performance of the left ventricle and the degree of involvement of the coronary arteries were comparable in these two groups. Seven inoperable patients were treated medically. Actuarial survival curves show a significant difference (p less than 0.01) in survival after two years between the operated cases (88%), the operable cases treated medically (60%), and the inoperable cases (57%). The decreased mortality of the operated cases corresponds also with a greater functional capacity in the survivors compared with that of the cases treated medically.

[Change in heart function in Duchênne de Boulogne myopathies at the severe progressive stage].

Left ventricular function was studied in 15 patients with rapidly progressive Duchenne de Boulogne muscular dystrophy. Only one patient had a previous history of cardiac failure. All patients had typical electrocardiographical changes. Haemodynamic and angiographic investigation was performed in all patients. Three groups of patients were distinguished according to angiographic criteria : group I comprising 7 normal patients. group II comprising 4 "intermediary" patients, and group III of 4 patients with hypokinetic cardiomyopathy. Segmental ventricular dyskinesis was observed in 6 patients. Mitral incompetence was present in 2 cases and mitral valve prolpse in 1 case. All patients had a normal resting cardiac index. Patients in group II and III had end diastolic left ventricular pressures greater than 15 mmHg. An intravenous angiotensin test was performed in 4 patients from groups I and II. Impaired left ventricular function was demonstrated in patients thought to be normal in the basal state. Finally, myocardial involvement in this group of patients runs a parallel course to the duration and severity of the peripheral muscular disease.

[Periarteritis nodosa-type vasculitis and infection with human immunodeficiency virus].

The human immunodeficiency virus (HIV) may be responsible for several types of vasculitis: leucocytoclastic vasculitis, granulomatous angiitis, angiitis associated with lymphoproliferative syndromes or necrotizing vasculitis including periarteritis nodosa (PAN). We report a case of PAN in a 62-year old HIV1-positive woman. The patient had no co-occurrent hepatitis B virus infection and was negative for antinuclear antibodies. She presented with sicca syndrome, necrotic purpura, myalgias and polyneuropathy. Skin, muscle and nerve biopsies showed signs of necrotizing vasculitis. Multiple microaneurysms typical of PAN were present on branches of the abdominal aorta. The symptoms due to vasculitis regressed after treatment with corticosteroids in bolus injections and plasmapheresis. AZT was not given owing to intolerance. The literature on vasculitis associated with HIV infection is reviewed.
