Two probiotics were tested as alternative treatment to limit the prevalence of the vertebral column compression syndrome (VCCS) in rainbow trout, compared with a preventive treatment with florfenicol. Either the antibiotic, or a lactic acid bacterium, Pediococcus acidilactici, or a yeast, Saccharomyces cerevisiae var. boulardii, was introduced into(More)
STUDY OBJECTIVES This study reports on the cardiorespiratory response to graded exercise in patients after venous switch operation for transposition of the great arteries. DESIGN Several small studies have documented a diminished exercise tolerance after Mustard repair for transposition of the great arteries, little information exists, however, about(More)
Iatrogenic third degree atrioventricular block due to alpha interferon is rare. The authors present a case which occurred with low dosage, regressed when treatment was withdrawn and reappeared when treatment was reintroduced. The physiopathological mechanism of disease of the conduction pathways and its general cardiotoxicity is not yet understood. The(More)
The authors report the case of an elderly sportsman presenting with the electrical signs of the syndrome described by Brugada. The absence of any serious clinical events in this patient questions the pejorative prognosis usually reported and the specific identity of this syndrome in relation to right ventricular arrhythmogenic dysplasia.
The growing numbers of elderly and cardiac patients are the consequence of progress in the prevention of the complications of coronary artery and valvular heart disease by surgery and revascularisation and improved treatment of hypertension which delays target organ complications by at least fifteen years. The elderly are particularly exposed to surgical(More)
Many patients with chronic cardiac failure may benefit from exercise rehabilitation. However, the usual protocols, which may lead to haemodynamic disturbances or induce arrhythmias, are rarely applicable in the most severe cases. Therefore, the authors developed a protocol of segmental rehabilitation where the same muscle groups as in global readaptation(More)
BACKGROUND Haemodynamic measurements taken at rest and during exercise showed that percutaneous transvenous mitral commissurotomy results in both acute and long-term improvement. However, the time lag before there is an increase in exercise and in peak oxygen uptake appears to be delayed and irregular. PATIENTS AND METHODS To assess the potential of(More)
The use of sublingual nitroglycerin in the stress test is a precious tool in everyday clinical cardiology. It has several indications in this context: 1) Confirmation of the diagnosis of myocardial ischaemia by eliminating a large number of false-positives with no marked variation of ST depression and performance after sublingual nitroglycerin in contrast(More)
Effort tolerance is reduced after correction of Tetralogy of Fallot. This prospective study investigated the cardiorespiratory response and the chronotropic function (mean follow-up 11.1 years) of 70 patients (43 boys and 27 girls) with an average age of 14.9 +/- 7.2 years (group 1) compared with 65 normal, sedentary subjects paired red for age and gender(More)
