[Les rickettsioses des ruminants domestiques transmises par les tiques: elements taxonomiques et diagnostic de laboratoire]

Tick-borne rickettsioses are diseases which remain comparatively unknown to field veterinarians. The authors present a literature review, focusing on taxonomic aspects and on laboratory diagnosis

[Detection of natural infections with theileria annulata on calves at first theileriosis season: comparison of the indirect fluorescent antibody test [IFAT] and blood smears]

The Indirect Fluorescent Antibody Test [IFAT] remains so far the most commonly used test for sero-epidemiological investigations on tropical theileriosis [infection of cattle with Theileria annulata]. The present studies evaluated the ability of both IFAT with schizont antigen [schizont IFAT] and blood smears to detect infected animals just after the theileriosis season. This evaluation was performed on a group of 89 calves of known infection status for T. annulata at first disease season, from farms with endemic stability for tropical theileriosis. An additional retrospective group of 84 cattle free of infection was also used for the estimation of the specificity of the schizont IFAT. The sensitivity and the specificity of schizont IFAT were 88.9% [64/72] and 97% [98/101], respectively. Blood smears showed a lower sensitivity of 63.9% [46/72]. The agreement between the two detection techniques and the infection status of the animals, evaluated by the Kappa coefficient, was 0.85 and 0.64 for IFAT and blood smears, respectively

[Food intake during and outside Ramadan]

We explored the effect of fasting in the month of Ramadan on the dietary pattern of a group of 130 healthy adults. During Ramadan, there was an increase in total energy intake, as a result of protein and lipid intake but not carbohydrate intake compared to the diet througout the rest of the year, in both students and parents. The meal eaten after sunset was an important contributor to calories [65%], lipids [74%], proteins [71%] and carbohydrates [56%]. These findings show the eating behaviour during Ramadan may contribute to improved nutritional status of people at risk of nutritional deficiency

L'hypercholesterolemie familiale a propos d'un cas

We report original observation about a child who has familial hypercholesterolemia and cardiopathy much severe aortic disease with mitral insufficiency. Aortic injury is orficial with very hypoplasic ring and very thick side. The type of the mitral injury is leaky because of annular dilatation and moderate big value prolapsus. Ostial atheromatous lesions of the right coronary artery are associated to this surgical cardiopathy correction was a konno type intervention with insertion of an Aortic sant jude value, aortic annula patch widering and mitral annuloplasty with carpentier annula insertion. This observation explain cardiac injury complexity seen in the course of familial hypercholesterolemia

Epidemiologie du diabete en Tunisie

The prevalence of diabetes was estimated by interrogation and biologic evaluation of the glycemy in a representative group of Nabeul's population aged between 35-50 years. The study of 692 persons include 46% men. The prevalence of diabetes was 6,3% compounded 3/4 of known diabetics. The prevalence was higher in the cities than in the countries. The corporeal mass index was significantly higher in diabetics. Obesity frequency was significantly different between diabetics and normals [54% versus 31%]. Arterial hypertension frequency was higher in diabetics who had a triglycerid level higher than normals [1,89 mmol/L versus 1,29mmol/L]
