[Exertional heat stroke: about 4 cases]

Exertional heat stroke is defined as hyperthermia associated with neurological signs related to intense physical activity performed in a hot environment. This is a medical emergency and life-threatening. In this study, we investigated four cases of exertional heat stroke hospitalized at the military hospital in Tunis [Tunisia] to describe the clinical, therapeutic and preventive characteristics and factors favoring this disease. Four young soldiers, 23 to 44 years older, have developed Exertional heat stroke after Intense and prolonged exercise. Exercises were performed in May and June, in high ambient temperature, high humidity and lack of wind. Three soldiers were in battle dress, a backpack and their weapon. Our four subjects had overweight, were not sufficiently trained and were highly motivated. Insufficient hydration and a diet rich in carbohydrates were noted. Upon hospitalization, patients were febrile and had neurological disorders, neuromuscular disorders, rhabdomyolysis and hemoconcentration. The medical care consisted of a rehydration and oxygen

Effets de la vitamine A sur les adaptations morphometriques apres resection etendue de l'intestin greele du rat

This work was conceived to study, in the rat short bowel syndrome, the effect of precocious administration of retinoic acid on morphometric adaptation in the remnant intestine. Mitotic index, villous height, crypt depth and mucosal aspect were determined in 2 groups of rats [n=12] after 60% small bowel resection 100 meiug of retinoic acid were perfused immediately after resection in the first group. Control group rats received placebo. Two similar groups [n=12] underwent intestinal transection with or without retinoic acid perfusion. Our results show that retinoic acid induced precocious and significant enhancement of all morphometric parameters when compared to placebo

[ incidence of nutritional education on the food intake regulation of young diabetics]

The aim of our study is to evaluate the effect of nutritional education [applied during young diabetic camps] on the nutrition knowledge acquisition and the effective application of this knowledge by young diabetics in their dietary intake composition. This study included ten volunteer pupils, aged from 12 to 15 years. Each meal provided was quantified before and after consumption to determine during three consecutive days the exact amount of food consumed. Our results showed that the young diabetic could regulate his energetic intake in accordance with his needs.He didn't modify the proposed food when it was normocaloric [2615 +/- 390 Kcal], but he increased his food intake near the recommended needs when the proposed food was hypocaloric [1766 +/- 283 Kcal] and decreased his consumption when the proposed food was hypercaloric [4271 +/- 511 Kcal]. Moreover, this study showed a significant negative correlation between the total energy intake and the amount of carbohydrates [r = -0.46, p < 0.01] and proteins [r= -0.70, p< 0.01], while it was positive between the first and lipid intake [r=0.63, p<0.01]
