Abstract
Background and Objective: Parasitic infection is one of the major health problems in the world. This study aimed at comparing the accuracy of two methods of direct examination and Formalin-Ether to detect the presence of parasitic infection among health-card applicants in Shahroud city, 2011.
Material and Methods: This cross-sectional study was conducted on 801 patients seeking health-card. From each patient, three consecutive stool samples were taken and investigated, using direct examination and formalin-ether method.
Results: The use of formalin-ether method in recognizing the parasitic infection specially giardia lamblia and entamobea coli is more than the direct method.
Conclusion: The formalin-ether method is a more sensitive method than the direct method. But in circumstances that is urgency to respond or aims to see the shape of trophozoite, the use of direct method is recommended.

Abstract
ABSTRACT
Background and objectives: Sarcoptes scabiei is a microscopic parasitic arthropod that penetrates into epidermis of the skin and causes scabies, a contagious disease that is one of the most common causes of dermatosis in the world.
Methods: We herein summarize published papers about Sarcoptes scabiei infestation in Iran. Databases including MEDLINE, Pubmed and Google scholar were searched using the following terms: Sarcoptes scabiei, mange, prevalence of Sarcoptes scabiei and scabies status in Iran.
Results: Overall, we found approximately 15 articles related to the prevalence of Sarcoptes scabiei infestation in Iran. According to these studies, the prevalence of Sarcoptes scabiei infestation has been rather high in Iran during war and in prisons and humid areas of the country.
Conclusion: In spite of the low prevalence of scabies, it is necessary to implant prevention programs continuously by reducing overcrowding, improving health education, personal hygiene, diagnostics tools, and screening and treatment of high-risk populations.
Keywords: Sarcoptes scabiei, Brief review, Iran.

Abstract
Background and objectives: Head louse, also known as Pediculus humanus capitis, is an obligate ectoparasite that is a distributed all around the world. The aim of present study was to determine the prevalence of head lice infestation in primary school students in Tabriz, East Azerbaijan Province, Iran.
Methods: Overall, 3,032 students (1,515 boys and 1,517 girls) from 33 primary schools in Tabriz were selected via multi-stage cluster sampling in 2018. The students were examined individually and privately by experts. Head lice infestation was confirmed by detecting adult or nymph or nits less than 1 cm from base of hair. Data analysis was carried out in SPSS software package (version 23). Association of participants’ characteristics with pediculosis infestation was evaluated using logistic regression and chi-square test at significance level of 0.05.
Results: Head lice infestation was present in 130 (4.29%) students, while the prevalence of this condition was higher in girls (2.11%) than in boys. The highest prevalence (6.05 %) was observed in children age 6 years old regardless of gender. The rate of head lice infestation was lowest among students aged ≥12 years (3.17%). There was a significant relationship between head louse infestation and parent’s occupation, family size, the frequency of combing and hair style.
Conclusion: Although the prevalence of head lice infestation in Tabriz is relatively low, screening and treating schoolchildren should be done continuously in order to reduce the infestation rate.

Abstract
Background and objectives: Soil contamination with Toxocara spp. eggs is the main source of human toxocariasis. The aim of this study was to determine rate of soil contamination with Toxocara spp. eggs in Yazd, central Iran.
Methods: During September 2014 to February 2015, a total of 220 soil samples were collected from public parks, primary schools, green areas, kindergartens, suburban areas, streets, residential complexes, backyards and a bus terminal in the city of Yazd, Yazd Province. Soil samples were investigated for the presences of Toxocara eggs by flotation technique using sucrose solution (1.2 g/cm3) and using light microscopy. Data analysis was carried out by SPSS (version 23) software package.
Results: A total of 220 soil samples from nine different places were examined. Of these samples, 51 (23.2%) were contaminated with Toxocara spp. eggs. The contamination rate was 26.3% in public parks, 19.2% in primary schools, 28.6% in green areas, 22.2% in kindergartens, 24% in suburban areas, 8.3% in streets, 18.8% in residential complexes, 19% in backyards and 28.6% in the bus terminal. There was no significant difference in the soil contamination rate with Toxocara spp. eggs between different sampling places (χ2 = 3.096, d.f = 8 and P= 0.92) and sampling areas (χ2= 2.289, d.f = 2 and P= 0.318).
Conclusion: The high rate of soil contamination with Toxocara spp. eggs in Yazd emphasize on the need for preventive measures, such as improving sanitation, providing public health education and controlling stray dogs and cats near children play areas.

Abstract
Background and objectives: Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease caused by the accumulation of large amounts of fat in the hepatocytes. Given that atorvastatin is effective for treatment of NAFLD, the present study investigated effects of high-fat/fructose diet (HFFD) with atorvastatin on liver enzymes and lipid profile in a NAFLD rat model.
Methods: Thirty-two male Wistar rats were divided into four groups: 1) normal control, 2) HFFD control, 3) HFFD + atorvastatin, and 4) normal + atorvastatin. The groups received HFFD for 15 weeks to induce hepatosteatosis. Atorvastatin was administrated at the dose of 10 mg/kg/day. Lipid profile and liver enzymes were measured after eight weeks of intervention.
Results: Triglyceride, cholesterol, gamma-glutamyl transferase, and aspartate transaminase were significantly reduced in the HFFD + atorvastatin group compared with the HFFD control group. In addition, cholesterol, high-density lipoprotein, alkaline phosphatase, and gamma-glutamyl transferase were significantly increased in the normal + atorvastatin group compared with the normal control group. Low-density lipoprotein increased significantly in the HFFD + atorvastatin group and the normal + atorvastatin group compared with other groups. There was a significant difference in the alanine transaminase levels between the groups taking atorvastatin. In fact, alanine transaminase level was lowest in the normal + atorvastatin group.
Conclusion: Atorvastatin improves the lipid profile and fatty liver and controls liver enzymes. Therefore, it can be used with caution to improve the lipid profile and reduce the complications of NAFLD.
