[Asymptomatic coronaro-cardiac fistula. Apropos of a case].

The case of a 20 year old woman with a right coronary-right atrial fistula is reported. The diagnosis was made during investigation of a continuous murmur and the tolerance was excellent. Aortic root angiography demonstrated a fistula between the initial part of the right coronary artery and a right heart cavity. Selective coronary angiography visualised pseudo-aneurysmal dilatation of the first segment of the right coronary artery, the calibre and trajectory of which was then normal. The medical literature suggests surgical correction even in asymptomatic cases because of the risk of spontaneous complications (cardiac failure 15 p. 100, endocarditis 7 p. 100, infection 4 p. 100). Since 1968, there has been no operative mortality in 145 subjects with isolated coronaro-cardiac fistulae without cardiac failure. In the case presented, the fistula was successfully closed under cardiopulmonary bypass and endoaneurysmorrhaphy was performed to remodel the lumen of the right coronary artery.

[Ceftriaxone (Rocéphine) in major African infectious pathology. Results at the Niamey Hospital (Niger) ].

Ceftriaxone is a wide-spectrum-third generation cephalosporin characterized by outstandingly high efficacy as well as pharmokinetic properties making it suitable for administration in a single daily injection. Ceftriaxone has been found to be useful for treatment of the very severe infectious pathology in countries where hygiene and medical superstructures are still rudimentary. Eighteen of 20 patients with purulent meningitis (13 to Neisseria meningitidis A, 3 to Streptoc. pneumoniae, 1 to Listeria and 3 aseptic) recovered (there being 2 deaths at the 36th hour) after a mean 6 days of hospitalization. Despite the very delicate patient condition, recovery was seen in all 11 cases of very grave bronchopneumopathy, generally due to Streptoc, pneumonia. A dose of 2 g/day in 1 or 2 IV injections is sufficient in the adult, 0.50 g in a single dose being injected to infants weighing less than 10 kg, Meningitis required 4 to 7 days treatment (9 days in a case of Listeria) while the treatment period was longer for respiratory infections. Seven patients had been refractory to treatment with beta-lactamines and/or aminosides, and no adverse drug reactions were noted.

[Attitudes and opinions of the Venezuelan toward fish as food].

A survey was carried out to obtain an overview of the consumers' attitudes and opinions towards fish in Venezuela. The city of Caracas was selected for this purpose because of its size (4,000,000 inhabitants, the largest in Venezuela). The survey showed that consumers had a high regard for the nutritional value of fish compared with competing foods, but considered it low in taste, and disliked bones and smell. The percentage of people that did not consume any form of fish was 17.5 and the percentage of people who consumed fish four times or more per month, was 44.2. Of the people interviewed, 62% preferred to purchase fish directly from fishermen.

[Tricuspid insufficiency and right traumatic ventricular aneurysm. Apropos of a case].

Tricuspid incompetence associated with a right ventricular aneurysm wa discovered after a non-penetrating thoracic injury. The severity of the tricuspid lesion was confirmed by phonomechanography, catheterisation and angiography. The mechanism was demonstrated by two-dimensional echocardiography: the right ventricular aneurysm was located in the right ventricular outflow tract. As the hemodynamic tolerance was good, surgery was not performed. A review of the literature found 41 other reports of traumatic tricuspid incompetence, and 4 cases of right ventricular aneurysm, only one of which was associated with tricuspid regurgitation. The points of interest of ths case: the rarity of the association, the good hemodynamic tolerance and the value of two-dimensional echocardiography for the diagnosis of ruptured chordae in the absence of surgical observations.

Theoretical and practical considerations in the application of killed poliovirus vaccine for the control of paralytic poliomyelitis.

This paper contains a summary of the principles upon which the preparation and use of killed poliovirus vaccine (KPV) are based, as well as a summary of earlier and more recent work suggesting the feasibility of formulating a KPV preparation that would be fully and durably effective in a one- or two-dose regimen. The essential factor in the preparation of such a vaccine is the inclusion of a sufficient mass of the immunizing antigen, for each of the three antigenic types of poliovirus, to induce the formation of humoral antibody and/or immunologic memory after the first dose. The results of a series of studies carried out in West African and Scandinavian countries are summarized, which suggest that such a vaccine should contain 40, 8, and 32 D-antigen units for types I, II and III, respectively. If the D-antigen unit measurement is to be used as a guide to KPV standardization, the details of the method of manufacture are important; in this regard, the method of vaccine preparation used at the Rijks Instituut voor de Volksgezondheid should serve as a reference standard for the preparation of vaccines expected to produce the effects described.

[Echocardiograhy in athletes].

The electrocardiogrammes and echocardiogrammes of 10 weight lifters and 20 endurance trained top class athletes (runners, basket ball players and cyclists) were analysed. The electrocardiogrammes confirmed the notion of a specific profile in endurance trained athletes with left ventricular diastolic overload pattern. The echocardiogrammes did not show increased left ventricular wall thickness in the resistance trained athletes. It did show however a clear increase in left ventricular internal diastolic dimension and posteror wall thickness--the anatomical substratum of the large heart in athletes--in some categories of endurance trained athletes (cyclists and basket ball players). No change in the indices of left ventricular performance was found in either group.

Fibrosing alveolitis and hepatitis B surface antigen-associated chronic active hepatitis in a patient with immunoglobulin A deficiency.

Fibrosing alveolitis is described in a 22 year old woman with immunoglobulin A (IgA) deficiency and hepatitis B surface antigen (HBsAg)-associated chronic active hepatitis. At lung biopsy HBsAg was detected by indirect immunofluorescence in the alveolar space but not in the septal fibrosis. We discuss the possible relationships between IgA deficiency on the one hand, and HBsAg-associated lung and liver diseases on the other hand.

[Severe pulmonary embolism and recurrent thrombophlebitis caused by hereditary antithrombin III deficiency].

Severe pulmonary embolism with thrombosis of the inferior vena cava was observed in a 16 year old girl with no risk factors and treated successfully by fibrinolytic therapy. Secondarily, despite heparino-therapy, upper limb venous thrombosis occurred. Investigation of the clotting factors in the patient and her family revealed a hereditary deficit of antithrombin III. The features of the haemotological diagnosis of this rare condition and the therapeutic implications are discussed.

[Artefacts during continuous electrocardiography by the Holter method].

Continuous ECG by the Holter method provides valuable information on the electrical activity of the heart but the interpretation of the playback may be made difficult by the presence of artefacts. The principal artefacts which may mimic arrhythmias or blocks, disturb QRS detection or deform the ventricular depolarisation are described. The majority are caused by incomplete preparation of the patient or the electrodes, but others may arise from a mechanical or electrical fault. Artefacts interfere with the automatic analysis of the tape, which is one reason for knowing the limitations of these systems of automatic analysis, and therefore control visual reinterpretation is necessary in cases where there is the slightest doubt. The presence of these artefacts is a limitation of the Holter method, the practice of which demands a certain amount of experience to avoid incorrect diagnoses which could lead to inappropriate or injustified therapy.

[A case of serohemorrhagic pericarditis (author's transl)].

The authors report the case of a 54 year old man with a tamponade and a serohemorrhagie pericarditis. From the cytology of the pericardiac liquid, a neoplastic origin is suspected and confirmed by the secondary appearance of pulmonary primitive localization responsible for death. The low frequency of such a mean of revelation is underlined together with the difficulties of an etiological diagnosis.
