World Journal of Gastroenterology 2007年第12期13卷 1833-1836页

AIM： To evaluate the clinical presentation, response to prophylactic therapy and outcome of children with cyclic vomiting syndrome （CVS） in Shiraz, Iran. 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.

Basin Analysis and Paleogeography of the Zagros Foreland Basin during the Maastrichtian, High Zagros Basin, Iran

引用

Journal of Earth Science 2024年第5期35卷 1527-1545页

作者： hossein Ghanbarloo Amrollah Safari Department of Geology University of Isfahan

A sedimentological investigation was carried out to reconstruct the paleogeography of the Zagros Foreland Basin. Based on the study of more than 1 000 rock samples, nine carbonate microfacies and three terrigenous facies were identified. The study reveals that the Maastrichtian succession was deposited in a widespread homoclinal ramp in the High Zagros Basin. Three(Gandom Kar area), two(Ardal area), seven(Gardbishe area), five(Shirmard area), two(Kuh-e-Kamaneh area), three(Kuh-e-Balghar area), and six(Murak area) of depositional sequences(3rd order) were identified. The thickness of the lowstand systems tract(LST) due to activities of local faults and subsidence in the southeast is more than in the central and northwest of the High Zagros Basin during the Early and Early Middle Maastrichtian. During the Middle Maastrichtian, the shallow and deep marine deposits were formed during the transgressive systems tract(TST) and highstand systems tract(HST) in this basin and the rate of subsidence in the center of this basin(Gardbishe area) is higher than in other areas and the platform was drowned in this area. The falling relative sea-level due to activities of local faults led to that marine deposits were absent in all parts of the High Zagros Basin(except the south part) during the Late Maastrichtian. Paleogeographical studies on the Zagros Basin during the Late Campanian-Maastrichtian showed the following results: shallow marine environments were developed in the southeast of this basin, and the turbidite, delta, and fluvial environments in the northwest were developed more than in other areas.
