Target: Head lice infestation is worldwide and it is considered as an important health issue not only in deprived societies but also in developed countries societies as well. The object of this project is to investigate head lice prevalence in primary schools in Sabzevar city.Research Method: This study was of type descriptive and in form of sectional studies which was done in 2015-2016. The Target population was entity of primary school students and sample was 1200 people population. Sampling was of simple-random kind and checklist were used for data collection. Then Data was registered (recorded) in SPSS V 19 software. analysis of data was done according to chi-square test description.Results: The number of studied students was 1200, 30.9% were boys and 69.1% were girls. The highest prevalence of head lice infestations was in cases where their fathers were free (81.5%), and their literacy level (65.66%). There was no correlation between the type of residential home and contamination of the research samples (P = 0.71). There was no relation between the students' bases (P = 0.32), the existence of a health educator (P = 0.9) and father's occupation with head lice infection (P = 0.54). Result: Head lice infestation (Pediculosis capitis) is still a crucial health issue worldwide. It is recommendable that proper information is provided to primary schools teachers so that appropriate utilization of their capabilities in students’ instruction, screening & treatment (Therapy) is made possible.

Background and purpose: Previous studies have shown conflicting results regarding to the relationship between shift work and lipid disorders. This study has investigated correlation between shift work and serum lipid.
Methods and Materials: An analytical cross sectional study was performed on a total of 2100 workers of Polyacryl Iran Company in 2013. The relationship between shift work, biochemical parameters, blood pressure and fasting blood sugar were investigated. SPSS (19) was used for data analysis. Comparisons of quantitative and qualitative variables were performed using, a one-way analysis variance (ANOVA) and Chi 2 tests respectively. The significance level defaults to 0.05.
Results: Total cholesterol average in 3-rotating shift workers (10/32 ± 50/171) was lower than total cholesterol average in the day-shift workers (19/34 ± 46/178) and 2-rotating shift workers (59/35 ± 15/178). ANOVA revealed a significant correlation between total cholesterol and shift work (p<0.001). The prevalence of total cholesterol ≥ 200 mg per dL was 25, 23.7 and 18.6% in day-shift, 2-rotating shift and 3-rotating shift workers respectively. Chi-square test showed that this is a significant difference (p<0.01).
Conclusion: This study was shown that total cholesterol and its prevalence was higher among 3-rotating shift workers than day workers and 2-rotating shift workers. So this study emphasizes on the importance of metabolic risk factors measurement among shift workers and prevent from this risk factors.
