ABSTRACT
Background and aim: Using new technologies has been emphasized in higher education in recent years. It seems that applying these technologies is helpful for teaching and learning experimental histology. However, the effect of changing the educational methods on student's learning has been questioned for a long time. In this study, the effect of classical education [using slide presentation of schematic histological photos] and new method of using microscope monitoring on final experimental histology scores has been compared in medical students
Methods: This experimental study was performed on 36 medical students who had selected histology course. Students were randomly divided into two groups. First group was thought by old method of slide presentation and second group was thought with new method of microscope monitoring. After finishing the educational course, one similar exam was taken from both groups and the student's scores were compared using student-t test in SPSS software [ver. 11.5]
Results: Based on the results of this study, the students' scores in the microscope monitoring group was 14.32+/-2.39 compared to the slide presentation group which was 13.18+/-2.18. Data analysis showed that there was no significant difference between the two groups [P>0.05]
Conclusion: Findings of this study demonstrated that using two different educational methods of slide presentation or microscope monitoring may not have significant effect on student's scores in their final exam
ABSTRACT
Thyme is a plant in Labiata family which different species of this herb affects the menstrual cycle and therefore is avoided in high doses especially during the gestational period. Assessing the effect of thyme Decoction consumption in 2nd gestational week on placenta and fetus in rats. In this study 10 pregnant Wistar rats were randomly divided into 2 equal groups. Animals in test group received thyme Decoction in 2nd week of gestation. On 20th day of pregnancy, the placenta was removed and weighed. The number of live, dead or reabsorbed fetuses were recorded. All fetuses were weighed and stereomicroscopically examined for any morphological abnormalities in limbs, vertebral column, or hear. Fetal height, fetal biparietal and placental diameters were also precisely measured. There were no significant differences in the number of live fetuses, between 2 groups. No dead or reabsorbed fetuses and no morphological abnormalities were observed in live fetuses. The live fetuses in both groups showed the same weight, height, and biparietal diameter but the length of tail in test group was longer than control group [p<0.05]. The placental weight was approximately identical in 2 groups, but its diameter in test group was smaller than the control group [p<0.05]. According to our findings, although the thyme Decoction consumption in 2nd gestational week did not lead to any abortion, due to its adverse effect on tail length and placental diameter, it is recommended that the thyme consumption be with precaution especially during the pregnancy
ABSTRACT
Intracranial meningiomas, with extension into the orbit through bone, the superior orbital fissure, or the optic canal, and optic nerve sheath meningiomas can lead to proptosis and visual loss. In this study we evaluated meningiomas's cases presented with proptosis in Ghaem Hospital from 1374 to 1384 with respect to etiological factors, clinical findings, imaging studies, histopathological and prognostication. we reviewed medical records of fifty patients that because of orbital mass and proptosis underwent cranio-orbital surgery, then cases of meningiomas [a with respect to pathology] selected. The chi-square test was used for the statistical analysis. Of fifty cases with proptosis, 6 cases [12%] were meningiomas with orbital involvement. In 6 meningioma's cases, 5 [83%] were intracranial sphenoid wing meningiomas with orbital extension and 1 [17%] was optic nerve sheath meningiomas. Of six patients with meningiomas's diagnosis, there were women [67%] and men. Mean age of patients in secondary meningiomas was 54.4 years [43-70 years] and in one primary meningiomas age was 21 years. In all cases there was decreased vision in addition to proptosis. The most common orbital meningiomas were secondary that arise intracranial. Visual loss is frequent; The most common cause of proptosis in neurosurgery ward is sphenoid wing meningiomas

Background: frequent bending, heavy labor, towing, frequent bending, previous history of low back pain age, parity and obesity are the risk factors for back pain during pregnancy. The most common region is sacroiliac joint. aim of this study is investigate of prevalence of low back pain in pregnant wemen referring to the department of gynecology and obstetrics of baqiyatallah hospital
Materials and methods: the study is cross-sectional after filling out of questionnaire and collecting the results and analysis. The prevalence of low back pain and other factors was studied 230 cases
Results: according to the results, prevalence of low back pain in pregnant women was 63.5% and the most common region was sacroiliac with prevalence of 97.9%[P<0/05]. there was not statistically significant relationship between low back pain and the others factor including age, Body mass index, heavy labor, age pregnant, exercise, job and [p>0/05]
Conclusion: by regarding to the high prevalence of low back pain in Iranian women, pregnant woman we suggest that pregnancy high weight and in old age with bad habits of sitting, daily works and standin works would increase the pain and woman have to prevent of this factors. Exercise suggested by a specialist would decrease the back pain
ABSTRACT
Background: Sore throat and cough are common complications after general anesthesia which are very unpleasant for patients and prevention of these events are very important
Objective: To determine the effect of topical betamethasone on reduction of sore throat and cough after general anesthesia
Methods: In this prospective analytic study [clinical trial] 60 patients who scheduled for elective surgery divided into two equal groups. Under equal condition of general anesthesia, in one group endotracheal tube which impregnated with betamethasone jell and in the other group, endotracheal tube without jell used for intubation. 24 hours after anesthesia, patients of both group follwed for sore throat and cough. Ultimately informations were analyzed statistically with X[2] test
Findings: During 24 hours after operation, 13.3% of patients in betamethasone group and 40% in control group had sore throat and there was significant statistical difference between two groups [P>0.05]. Also 10% of patients in betamethasone group and 20% in control group had cough postoperatively but there was no significant statistical difference between two groups [P>0.05]
Conclusion: Using the endotracheal tube with betamethasone jell reduces postoperative sore throat significantly but has not significant effect on reduction of postoperative cough
ABSTRACT
Background: the first basic step in formulating any quality improvement program is recognizing consumers' perceptions and expectations of service quality and determining the quality gap, then adopting guidelines to eliminate the gap
Objective: to assess the service quality gap in Kashan district health centers, based on consumers' perceptions and expectations
Methods: a sample of 300 females' health care consumers completed the research questionnaire. The SERVQUAL instrument administrated to assess the quality of services provided by health centers. To analyze data, descriptive and analytic statistic and correlation coefficient were applied
Findings: results indicated that there was an overall service quality gap between respondents' perceptions and expectations. The smallest gap was in tangibility dimension and the largest in responsiveness. Age and literacy respectively had direct and indirect significant correlation to quality gap
Conclusion: there was a quality gap in services. Thus, improvements are required across all the five dimensions, namely tangibility, reliability, responsiveness, assurance and empathy
