Background and purpose: Study of the geographical distribution of Enterobiasis (Oxyuriasis) not only helps in early diagnosis and treatment of the disease but alsoprovides more informationin recognizing the factorsaffectingthetransmissionof parasite in children. The aim of thisstudy was to investigate the geographical distribution of the diseasein Mazandaran province as a common helminthes disease during 1991 to2013. Materials and methods: This review study was performed by collecting the data onthe geographical distribution of disease during 22 years. Data was obtained by reviewing the published literature and Internetsearchengines. Data was then classified and Arc GIS, 9.2 was applied to map the geographical distribution of thedisease. Results: According to this study, the maximum levels of infection with Enterobiasis were seen in nurseries in Babol (33.6%) in 1998 and in girls attending nurseries in Sari (29.5%) in 1999. The mean prevalence of disease in Bahshar, Sari, Babol and Fereydunkenar were more than 4% which was found to be more in children. In western regions of the province, Tonekabon was found with a high prevalence of Enterobiasis (2-4%), while in central region of Mazandaran Joibar and Nekahthe prevalence rate was less than one percent. Conclusion: The study of geographical prevalence of Enterobiasis during 22 years has shown the patterns of disease distribution in Mazandarnprovince. These results could be beneficial in diagnosis and treatment of Enterobiasis and also in future studies.

Background and purpose: Accurate information on clinical and laboratory findings of parasitic diseases in medical centers could be effective in evaluating various aspects of their disease. Therefore, the aim of this study was to evaluate the clinical and preclinical findings of the intestinal parasitic infections in patients in gastrointestinal clinics in Sari, Iran, 2006 to 2015.

Materials and methods: A cross-sectional study was carried out using the medical records of 300 cases of gastrointestinal disorders with intestinal parasitic infections. Clinical and laboratory data were collected and analyzed in SPSS V.16.

Results: Among the patients with parasitic infections there were 57.7% females, 64.3% lived in rural areas, 81% were married, and 40% were illiterate or had primary school educational levels.  The most important parasitic diseases in patients were Giardiasis (44.7%), Amebiasis (12.3%), Enterobiasis (10.6%), Trichostrongylus (10.2%), Strongyloidiasis (9.78%) and, Hymenolepiasis (6.38%). Abdominal pain, bloating, and diarrhea were the most common symptoms.

Conclusion: According to this study, intestinal parasitic infection is a high priority for diagnostic purposes in gastrointestinal clinics. Therefore, diagnosis is important for appropriate treatment. Future studies are suggested to use sensitive and specific methods such as molecular methods to identify the parasites.
