Background & Objective: Pizotifen is an alternative option for prophylactic treatment of migraine
headache. This study aims to compare the effi cacy and safety of pizotifen with sodium valproate; one
of the most-widely used drugs in migraine prevention. Methods: This was a single blind, randomized,
parallel-group study. After a 4-week baseline evaluation, patients with episodic migraine were randomly
assigned to get either sodium valproate or pizotifen for a period of 12 weeks. Patients were asked to
fi ll a headache diary through the study. Headache characteristics and the possible side effects were
evaluated throughout and at the end of trial. Results: Forty two patients aged 20 to 49 were recruited
to the study. With both drugs, the frequency, intensity and duration of headaches were signifi cantly
reduced (p < 0.05). Except for headache duration, pizotifen was signifi cantly superior to sodium
valproate in the headache parameters assessed. Total reported side effects were initially higher in
patients who received pizotifen (37 vs. 22; P= 0.038); however, persistent side effects were lower for
pizotifen (6 vs. 10; P= 0.22).
Conclusions: The results of this study suggest that pizotifen is a safe and effective drug in migraine
prevention.

OBJECTIVES: Rates of attempted deliberate self-poisoning (DSP) are subject to undercounting, underreporting, and denial of the suicide attempt. In this study, we estimated the rate of underreported DSP, which is the most common method of attempted suicide in Iran.METHODS: We estimated the rate and number of unaccounted individuals who attempted DSP in western Iran in 2015 using a truncated count model. In this method, the number of people who attempted DSP but were not referred to any health care centers, n0, was calculated through integrating hospital and forensic data. The crude and age-adjusted rates of attempted DSP were estimated directly using the average population size of the city of Kermanshah and the World Health Organization (WHO) world standard population with and without accounting for underreporting. The Monte Carlo method was used to determine the confidence level.RESULTS: The recorded number of people who attempted DSP was estimated by different methods to be in the range of 46.6 to 53.2% of the actual number of individuals who attempted DSP. The rate of underreported cases was higher among women than men and decreased as age increased. The rate of underreported cases decreased as the potency and intensity of toxic factors increased. The highest underreporting rates of 69.9, 51.2, and 21.5% were observed when oil and detergents (International Classification of Diseases, 10th revision [ICD-10] code: X66), medications (ICD-10 code: X60-X64), and agricultural toxins (ICD-10 codes: X68, X69) were used for poisoning, respectively. Crude rates, with and without accounting for underreporting, were estimated by the mixture method as 167.5 per 100,000 persons and 331.7 per 100,000 persons, respectively, which decreased to 129.8 per 100,000 persons and 253.1 per 100,000 persons after adjusting for age on the basis of the WHO world standard population.CONCLUSIONS: Nearly half of individuals who attempted DSP were not referred to a hospital for treatment or denied the suicide attempt for political or sociocultural reasons. Individuals with no access to counseling services are at a higher risk for repeated suicide attempts and fatal suicides.

OBJECTIVEThis research analyzes data on road traffic accidents (RTA) in Fars province, whose roads are among the highly dangerous ones in Iran. It investigates educational level and age involved in RTA in order to discover patterns that can prevent or decrease accidents.
METHODSThis research made use of data visualization techniques to find hidden patterns. The data included mortality rate related to RTA in Fars province and were obtained from Fars Forensic Medicine Registry covering a period of 1 year from March 21, 2010 to March 21, 2011. All data were analyzed using SPSS 11.5. The results were reported as descriptive indices such as frequency (percentage). The Chi-square test was applied to the data concerning educational level and age. P value less than 0.05 was considered significant.
RESULTSIn the mentioned period, 1 831 people were killed, out of whom un/lowly educated people (69.6%) accounted for the highest mortality rate. The significant relationship between educational level and mortality rate was found (X2 equal to 275.98, P less than 0.0001).Also three was a significant association between age and mortality rate (X2 equal to 371.20, P less than 0.0001). Young people (age between 20 and 29 years) contribute to higher RTA mortality rate compared with other age groups.
CONCLUSIONThe educational level and age are significantly correlated to mortality rate. The youth and un/lowly educated people suffer more fatal RTA.

OBJECTIVES: Self-reporting can be used to determine the incidence and prevalence of hypertension (HTN). The present study was conducted to determine the validity of self-reported HTN and to identify factors affecting discordance between self-reported and objectively measured HTN in participants in the Ravansar Non-Communicable Diseases (RaNCD) cohort. METHODS: The RaNCD cohort included permanent residents of Ravansar, Iran aged 35-65 years. Self-reported data were collected before clinical examinations were conducted by well-trained staff members. The gold standard for HTN was anti-hypertensive medication use and blood pressure measurements. The sensitivity, specificity, positive and negative predictive values, and overall accuracy of self-reporting were calculated. Univariate and multivariate logistic regression were used to examine the discordance between self-reported HTN and the gold standard. RESULTS: Of the 10 065 participants in the RaNCD, 4755 (47.4%) were male. The prevalence of HTN was 16.8% based on self-reporting and 15.7% based on medical history and HTN measurements. Of the participants with HTN, 297 (18.8%) had no knowledge of their disease, and 313 (19.9%) had not properly controlled their HTN despite receiving treatment. The sensitivity, specificity, and kappa for self-reported HTN were 75.5%, 96.4%, and 73.4%, respectively. False positives became more likely with age, body mass index (BMI), low socioeconomic status, and female sex, whereas false negatives became more likely with age, BMI, high socioeconomic status, smoking, and urban residency. CONCLUSIONS: The sensitivity and specificity of self-reported HTN were acceptable, suggesting that this method can be used for public health initiatives in the absence of countrywide HTN control and detection programs.
