Studying the epidemiology and impact of headache can help improve patient care, estimation of burden of disease and classification systems. Migraine is common worldwide and has a geographically variable prevalence in the world. Moreover, its peak of incidence is the age of 20-30. The aim of this study was to determine the prevalence of migraine among the medical students in order to plan for future health interferences. In this cross-sectional study 631 students filled out a questionnaire designed according to the criteria of the international headache society. The data were analyzed using SPSS software (release 12) and descriptive statistics. 76.6% of the subjects were female and 23.4% of them were male. The females were 20.6 and males were 21.4 years old on average. The total prevalence of migraine was 7.3% (1.6% with aura, 5.4% without aura and 0.3% with both of them). Moreover, females, single subjects and students of medicine, except the migraine with aura that was more prevalent among students of associate degrees. A positive family history of headache was found in 45.6% of the students. 65.2% of those suffering from migraine had not referred to a physician and were unaware of their headache. Compared to similar researches there is a low prevalence of migraine among the students but most of the students do not take measures to cape with and treat them in the proper manner. This requires necessary health interferences

The role of circulating lipids in the pathogenesis of ischemic stroke remains unclear despite 3 decades of research. Since ischemic stroke is one of the important causes of death or disability in the world. Finding its risk factors can play a crucial role in health interferences.This study was conducted to investigate the relationship between blood lipids and ischemic stroke. This wasa case-control study conducted in 2002. The case group were patients who were definitely diagnosed to have ischemic stroke for the first time. An equal number of control subjects (with the same age and sex) were selected from other hospital wards. These two groups were compared in terms of the blood lipids. The collected data were analyzed using SPSS software (release 12) and statistical methods such as ANOVA and multivariate regression. In this research 132 cases were compared with equal number of control subjects. The subjects in both groups were 64.1 years old on average. The mean level of total cholesterol was significantly higher in case group (p=0.001). The mean level of Triglycerides had no significant difference in two groups. Regarding the findings of the present research, offering strategies to lower the chlestrol level through primary prevention as well as drug interferences especially in the groups with other risk factors of stroke, seems to have a significant role in the prevention of ischemic stroke.

Temporal arthritis (TA) is a systemic inflammatory vasculitis with unknown etiology, which involves large and medium sized arteries. A wide spectrum of systemic, neurological and ophthalmological complications appears in the course of the disease the most serious of which is visual impairment leading to permanent blindness in 60% of the cases. TA is diagnosed through an elevated ESR (>60 mm/Hg) and pathological findings of arterial biopsy. It is considered as one of the urgent neurological cases in which the patient should be treated with corticostroid immediately after diagnosis. The subject of this research was a 62-year-old male who had had headache associated with fatigue, night sweats and low mood for four month. The diagnosis of TA was made considering an elevated ESR and temporal artery biopsy findings. Treatment with prednisolone was initiated and continued for 19 months resulting in complete recovery.

Despite the ever increasing use of oral contraceptives there is uncertainty about the stroke risk associated with their use. Some cases of pulmonary Emboli and stroke have been reported among women taking these pills. The present research was conducted to investigate the relationship between taking contraceptive pills and the risk of ischemic stroke. In a case-control study, women with definite ischemic stroke were selected from Alavi Hospital in Ardabil who had no prior stroke. The control group was age-matched (± 3years) to cases and were selected from other wards of the same hospital. A questionnaire was administered to elicit information about prior exposure to various risk factors, including the oral contraceptive pill (OCP). The data were analyzed by SPSS software (Ver. 12) and statistical methods such as chi-square, multivariate regression and ANOVA. The risk factor were estimated by odds ratio. OCP consumption was associated with an increased risk of ischemic stroke (OR=5.4 95% CI=1.1-5.3), and after adjustment for other risk factors of stroke it was OR=2.7 (95% CI=0. 95-7.2) with p=0.05. According to this study there was weak evidence for an association between ischemic stroke and OCP consumption. Extended studies are needed to clarify the relationship between risk of stroke and the present/ past use of OCP.
