Iron status of Libyan infants with urinary tract infection

Serum iron, serum total iron binding capacity and transferrin saturation levels were measured in 45 infants, of whom 19 had urinary tract infections confirmed by positive suprapubic aspiration. The control group comprised 26 healthy infants with negative results. Mean serum iron and transferrin saturation values were significantly lower in infants with urinary tract infection compared with the control group [P < 0.01 and P < 0.001 respectively], especially if the cultured organism was Escherichia coli [P < 0.01, P < 0.02]. Total iron binding capacity was within the normal range. We conclude that iron deficiency is not a major factor in the etiopathogenesis of urinary tract infection in Libyan infants

Bronchoconstrictor effect of exercise in healthy Libyan children in Tripoli

To study the effects of short-term exercise on pulse rate and peak expiratory flow rate in healthy Libyan schoolchildren, 650 healthy students [330 boys, 320 girls] aged 4.5 years to 14.9 years were selected from four randomly chosen Tripoli primary schools. Pulse rate and peak expiratory flow rate were measured at rest in standing position and immediately after rhythmic short-term exercise. Exercise markedly increased pulse rate [mean differences being significantly higher in girls than boys] and markedly reduced peak expiratory flow rate [mean difference being significantly higher in boys than girls]. We found 10% of the children had a reduction in peak expiratory flow rate > or = 15% from the baseline
