[Activities of enzymes synthesizing catecholamines in areas of the brain stem in sudden infant death].

In victims of Sudden Infant Death Syndrome, the activity of phenylethanolamine-N-methyltransferase was found to decrease in the nucleus retroambigu, the Kolliker-Fuse nucleus and the C 2 area of medulla, whereas a decrease in the dopamine-beta-hydroxylase activity was found only in the C 2 area. These results suggest a hypoactivity of adrenergic neurons in respiratory and cardiac centres in the Sudden Infant Death Syndrome.

[Sedative measures during surgery on old patients. Result on ocular tension (author's transl)].

An attempt of sedative procedures associated with a locoregional anesthesia was performed on fifty old patients before cataract operation. The blood gases, the blood pressure and the heartrate were measured and the behaviour of the patient just before he awoke was examined to determinate the sedative value. A parallel study revealed a decrease of the intra ocular pressure of 2,5 mm d'Hg due to a slight decrease of the blood pressure and to the effect of the neurolep mixture: the Innovar. This method seems to be very satisfactory in Ophthalmology.

[Cardiac findings in bilharziasis without pulmonary arterial hypertension].

1. A systematic search was made for cardiac abnormalities (clinical, radiological and ECG) and haemodynamic disorders (catheterisation of the right side of the heart and pulmonary artery) in 37 cases of confirmed biharziasis. It was generally found that:--14 patients (37.8%) had no symptoms;--8 patients (21.6%) had pulmonary hypertension (PH) with the corresponding cardiac signs (these will be reported separately);--15 patients (40.5%) had cardiac signs with no PH; these are studied in this paper. 2. Iatrogenic myocarditis was noted on the ECG. It was found in 3 of the 37 cases (8.1%). This points to the importance of careful monitoring of treatment. There was also ECG evidence of anaemyic myocardial changes in 5 cases of the 37 (13.5%). In 3 of these 5 cases this was found to be due to bleeding. Hypertensive myocardial disease was found in 1 case (2.7%), a patient with renal disease. Myocardial signs were also found in 3 cases because of coexistant disease. 3. Three cases (8.1%) remain in whom there were ECG changes, but without PH and without any other definable cause. These could have been due to bilharzia myocarditis; the authors review the experimental and clinical evidence for such a possibility. The real incidence of this condition remains to be determined. 4. Although there was no such case in this series, the authors suggest that bilharziasis might cause endomyocardial fibrosis (EMCF). 5. The authors put forward the hypothesis that the pulmonary arteritis is a tissue immunological reaction, and also that the myocarditis (and possibly the EMCF) is a manifestation of circulating antibodies.

[Constrictive fibrous endocarditis. Surgical treatment].

An anatomo-clinical entity, fibrous constrictive endocarditis can betreated srugically, and we carried out this procedure for the first time in 1971, since when we have used it seven times; it consists of an internal stripping of one or both centricles, with removal of one or both the mitral and tricuspid valves. The results were encouraging in the first two cases, and so good in the succeeding ones that this endocardial resection could be put forward as the treatment of choice for a condition whose aetiology is still unclear.

[Study of 20 cases of apparently primary pulmonary arterial hypertension].

The authors have studied the clinical, electrocardiographic, radiological, phonomechanographic and haemodynamic features of 20 cases of apparently primary pulmonary hypertension of fairly severe degree. An attempt has been made to correlate on the one hand the haemodynamic values, and on the other the clinical findings, ECG signs of right-sided preponderance, the size of the artery to the right lower lobe on X ray, and the phonomechanographic results. Particular importance is given to a discussion on the aetiology. It is recalled that syphilis can be excluded, that it is possible the operate on thromboses, and that bilharzia and the haemoglobinopathies may play a part which is yet to be defined.

The surgical treatment of constrictive fibrous endocarditis.

Constrictive fibrous endocarditis is a pathological entity described by Loëffler in 1936. Its etiology is unknown. The clinical course is characterized by an evolution towards cardiac insufficiency leading rapidly to a fatal outcome. Moderen paraclinical investigations are necessary to assess the diagnostic. Caridac catheterization brings the proof of adiastole and angiogardiography reveals the shape of amputation of the ventricle with auriculoventricular regurgitation. The operative procedure consists of resection of the ventricular fibrosis including the valves and auriculo-ventricular valve replacement by a prosthetic valve. The disease affects both Caucasians and Negros. Our experience includes 5 cases. The indications for operation and their results are discussed.

[200 valvular disorders seen in Abidjan].

The authors have made a retrospective study of the case notes of 200 patients with valvular disorders seen over the course of 35 months (excluding those due to constrictive endocardial fibrosis). The cases represent the frequency of cardiac failure, especially in the mitral group. The authors found 61% to have mitral valve disease, 28.5% aortic valve disease, and 9.5% disease of more than one valve. Mitral valve lesions were found most frequently in young females (average age 26 years); aortic valve lesions were found more commonly in an older age group of men (average age 47 years). The authors discuss the aetiology. Rheumatic fever was responsible in 60% of cases, and caused particularly mitral valve disease. Atherosclerosis and syphilis were the commonest causes in the aortic group. Indications for surgery were found in 74 cases (37%), and 28% of these were closed heart techniques. The course of the disease is best appreciated during the first hospital admission. The mortality rate was 5.5%, and most of the patients (65%) were stabilised on treatment.
