Background & Objective: Dyslipidemia and smoking are among the most important medical problems in human society. Their share in the mortality of coronary heart disease (CHD) has led to multiple investigations about them. This study was done to determine the prevalence of dyslipidemia and the effect of cigarette usage on it. Materials & Methods: This epidemiological cross-sectional study was carried out on 9632 persons selected randomly in Tehran urban with a minimum age of 20 years and over. We measured fasting blood sugar, blood sugar 2 hours after 75 grams oral glucose, triglyceride, total cholesterol, LDL cholesterol, HDL cholesterol. Degree of physical activity was registered according to Lipid Research Clinics classification. Anthropometrics data, social condition, family history and smoking exactly delineated. Our patients were divided into: those having normal lipid profile and primary dyslipidemia (without any risk factor for dyslipidemia) and secondary dyslipidemia (having one or more risk factors such as diabetes mellitus). ANOVA, t.test, and logistic were used to analyze the level of significance. Results: Our population sample consisted of 5619 female and 4013 male. 68.5% of our cases had dyslipidemia. 65.8% of females and 72.3% of males had at least one type of dyslipidemia. There were 1085 smokers (11.4%) that 73.2% of them were dyslipidemic. With comparing smokers to nonsmokers shows that in smokers HDL.cholesterol, LDL.cholesterol and total cholesterol had decreased and triglyceride increased (p<0.05). Conclusion: Tehran population suffers from dyslipidemia. Large number of secondary dyslipidemia and smoking highlighted the importance of education to overcome to these preventable and modifiable factors.

Background and Objective: Helicobacter pylori infection is a chronic bacterial infection in humans, and its link to epilepsy has been reported in some studies. This study was conducted to compare the frequency of Helicobacter pylori infection in patients with and without epilepsy.
Methods: This case-control study was conducted on 234 patients with focal and generalized epilepsy (the case group consisted of 88 males and 146 females) referring to Alavi Hospital in Ardabil, Iran and 234 individuals without epilepsy (the control group consisted of 88 males and 146 females) during 2019. Stool samples were taken from the subjects to assess the Helicobacter pylori stool antigen. Demographic information, including age, gender, place of residence, a history of alcohol, cigarette, hookah, and opium use, and the test result of the Helicobacter pylori stool antigen, were collected in a checklist.
Results: The frequency of Helicobacter pylori infection was determined to be 67.2% in the case group and 71.1% in the control group, and no statistically significant difference was found between the case and control groups. Cigarette and opium use had statistically significant relationships with epilepsy (P<0.05). Moreover, opium users had a 6.92 times higher odds rate (OR) of contracting Helicobacter pylori infection than other individuals (CI 95%=1.05-45, OR=6.92, P<0.04).
Conclusion: No difference was observed in Helicobacter pylori infection between individuals with and without epilepsy.
