METHODS： During a period of 11 years （March 1994 to March 2005）, 181 consecutive children with a final diagnosis of CVS were evaluated, treated and followed in our center. Patients were randomized to receive either amitriptyline or propranolol as prophylactic treatments. RESULTS： There were 88 boys and 93 girls with mean age of onset of symptoms of 4.9 ± 3.3 years （range, neonatal period to 14 years）, the mean age at final diagnosis was 6.9 years （range, 1.5 to 14）, and the mean duration between the onset of the first attack and the final diagnosis of CVS was 2 ± 1.81 years （range, 1/6 to 8）. The mean duration of each attack was 4.26 days （range, from few hours to 10 d） and the mean interval between the attacks was 1.8 mo （range, 1 wk to 12 too）. The time of onset of the attacks was midnight to early morning in about 70% of cases. Amitriptyline was effective in 46 out of 81 （56%） patients （P 〈 0.001）. Propranolol appeared to have a superior action and was effective in 74 out of 83 （92%） patients （P 〈 0.0001）. CONCLUSION： There is a significant lag time between the onset of clinical symptoms and the final diagnosis of CVS in our area. In patients with typical clinical presentations of CVS, who are examined by an experienced physician, invasive workup is not necessary. Propranolol appears more effective than arnitriptyline for prophylactic use in children with CVS.展开更多

Distance of collected specimens in this study is 800 km far away from the previous reports of this species in Iran in the coastal plain of Fars and Kerman provinces as well as the lower Mesopotamian plain in Khuzestan. Our specimens were collected during night on loose sand among scattered low desert shrubs. New updated distribution map for the species is presented which extends the distribution of this lizard into eastern and southeastern Iran. Morphometrics and morphological characters of the collected specimens along with notes on ecological aspects of the study area are provided.展开更多

In this research,microbiostratigraphy and depositional environmental implications related to the Shahbazan Formation at the northern flank of Chenaerh anticline are discussed. Carbonate sequences of the Shahbazan Formation consist mainly of large benthic foraminifera along with other skeletal and non-skeletal components.Two biozones have been recognized by distribution of large foraminifera in the studied area that indicate middle Eocene age( Lutetian). Based on analysis of large benthic foraminiferal assemblages and microfacies features,7 different microfacies have been recognized,which can be grouped into three depositional environments: inner,middle and outer ramps.展开更多

This study was designed to examine the behaviors of adolescent pedestrians in southern Iran. Methods： This is a descriptive analytical cross-sectional study. The study population consisted of high school students in Shiraz, capital city of Fars Province, Iran. Five hundred and sixteen students were selected by multi-stage sampling. Data were collected by the use of three questionnaires, which included Persian copies of adolescent road user behavior questionnaire （ARBQ）, Duke University Religious Index （DUREL）, as well as the context and independent variables questionnaire. Results： The results showed that a decrease in dangerous behaviors on the road resulted in an increase in respondents＇ intrinsic religiosity. Also, engagement in unsafe crossing behavior in the road decreased with increasing respondents＇ intrinsic religiosity. Another finding showed that female students were less involved in dangerous play and planned protective behaviors on the road. Conclusion： Findings clearly indicate that intrinsic religiosity has a significant role in reducing the risky road behaviors of students. Hence, religion may improve road safety in school students＇ road behavior in Iran.展开更多
