Background: Egypt is ranked the third country in the world with highest mortality rates due to road traffic accidents. The commonest cause of accidents was inattention of the driver. Driver inattention can be caused by practicing any activity other than driving or by sleepiness. Sleep at wheels can be caused by poor sleep habits, shift work, sleep disordered breathing, other sleep disorders as chronic insomnia, illicit drug abuse and medical disorders.

Methods: A cross sectional study including 324 male commercial drivers. The following data was collected history of accidents, the driving behavior including mean daily driving hours mean driving years mean daily sleep duration, shift work, seat belt, tea/coffee while driving and driving after meals. The sleepiness was assessed by history of excessive daytime sleepiness, Epworth sleepiness scale, Functional outcome of sleep questionnaire, chronic insomnia, nodded while driving, naps, risk for obstructive sleep apnea and history of comorbidities. Assessment of urine tetra hydrocanabinol (the major active ingredient in marijuana and hashish) was done. Driver’s characteristic included education level, vehicle type license class road and nature of work.

Results: Prevalence of ever exposure to accidents is 25%. Independent predictors of accidents were urine THC (OR=5.3), nodding during driving (OR=4.6), Berlin questionnaire (OR=2.5), STOP Bang questionnaire (OR=1.5), FOSQ (OR= 0.9), mean daily total sleep hours (continuous) (OR=0.9).

Conclusion: Accidents were common among studied group of drivers. It is recommended to screen drivers for urine THC, identify nodding during driving, Berlin questionnaire, STOP Bang questionnaire, FOSQ and mean daily total sleep hours to predict the driver with high risk of the sleep related accidents.

Objectives: To analyze dreams characteristics and their relation with the psychological status in postmenopausal women.

Material and Methods: 200 non-hysterectomized women were interviewed: Group I, premenopausal and Group II, postmenopausal. The last three dreams, the prevalence of nightmares and important situations in daily life were documented. The What’s My M3 test was used to evaluate the psychological status. Comparison among the groups was done with Mann Whitney U test and Chi square. Results: After excluding those with hormonal treatment or who didn’t met the inclusion criteria remained in group I, 76 and in group II 95 women. The median of age was 46 (40-50) and 61 (50-84) years for group I and II respectively. There weren’t any differences among the groups in the What’s My M3 score. The frequency of nightmares was greater in group II: group I, 31.8% and group II, 68.2%. In both groups, dreams were related with daily activities and also were a greater percentage of women with nightmares and What’s My M3 score ≥ 33. Actual diseases were related with nightmares (p < 0.023).

Conclusions: Nightmares were more frequent in postmenopausal women and had a relationship with the psychological status in both groups.
