[Effect of smoking on weight and cardiopulmonary capacities in young athletes].

The aim of the study was to determine wether smokers practising sports have reduced weight, if recuperation time after moderate exercise and maximal aerobic power were lowered. Thousand young soldiers [50 smokers (S), 50 no smokers (NS)] averaging 24 years in age were studied. The subjects performed to exhaustion on Ruffier test, then a maximal exercise with Cooper test. Several biometrical and physiological parameters were evaluated: weight (W), percent of body fat (PBF), body mass index (BMI), maximal oxygen uptake (VO2 max) and recuperation index (RI). Kinetics of heart rate (HR) were studied for 7 min considering time constant (1 min) and delay for recovery. The smokers showed significant differences for W (p < 0.001), PBF (p < 0.05), VO2 max (p < 0.01) and recuperation index (p < 0.001). Maximal aerobic power were 45.8 +/- 2.7 and 50.3 +/- 3.2 ml/kg/min for S and NS, and RI were 7.5 +/- 0.9 (S) and 5.0 +/- 1 (NS). figure 1 shows that HR recovery of S has generally two components: the first was fast, the second was a slone none. The smokers who presented a great dependence to tobacco smoking had a significant lower RI (p < 0.001) as those subjects with little tobacco dependence (Table 5). The smokers had lower values of VO2 max, and there exists a tobacco dependence difference. Recuperation time for the aerobically well trained S subjects was more rapid during the lactic phase. Note that correlations obtained between the VO2 max and RI were significant (r = - 0.788; p < 0.05). The smokers and no smokers differences are discussed with reference to nicotinemia effects and the sympathetic-parasympathetic unbatance of influences. The comparison of smokers groups concerning cardiovascular data led to suppose that there exists a tobacco dependence difference in regards of the catecholaminergic sensitivity. In conclusion, this study showed that smoker practising a physical activity have a reduced weight, a higher recuperation time and an anaerobic limitation influenced by the state of tobacco dependence.

[First urinary infection in infants aged less than 3 months. Diagnostic and therapeutic aspects from 44 cases].

While studying retrospectively 44 cases in infants less than 3 months with urinary tract infection, clinical, bacteriological and radiological aspects have been analyzed. Clinical symptomatology were chiefly fever and digestive symptoms (anorexia, vomiting) associated with poor weight gain. Among the causative bacteria, E. coli was the most frequent (88%) with ampicillin resistance in 26% of them. Diagnosis difficulties associated with urine collection with a bag, frequently contaminated, have to be emphasized. It is therefore necessary, except in case of emergency to repeat urine collection before treatment. Among 35 infants investigated radiologically, the urinary tract was abnormal in 46% (48% boys and 40% girls). The localization of the abnormality was upper in 16% and lower (reflux) in 43%. Ampicillin alone or associated with an aminoglycoside was the most common treatment (33 cases). Urine sterilization has always been obtained.
