Abstract
Background & Objective: First aid education constitutes a major priority area for the Iranian Red Crescent. The present study assessed the student volunteers' knowledge of first aid procedures and their attitudes concerning strategies for community education.
Methods: In this survey 5626 volunteers were selected based on a complex sampling design, in 5 different provinces of Iran.
Results: A total of 3581 students (63.7%) had attended the Red Crescent's first aid training courses. The mean knowledge score of the sample was 9.36 out of a maximum of 18 (CI 95%= 9.29-9.43), with only 674 subjects (11.9%) showing a high level of knowledge. Having training prior attending in this course and higher education were statistically significant related with their knowledge score (p<0.05). The mean score of their attitude was 33.60 out of a maximum of 45 (95% CI = 33.41-33.79), and only it was found to be related to previous training (p = 0.04).
Conclusion: IRCS should expand its first aid training for young volunteers. This health educational programs should be supported by multidisciplinary work by governmental organizations such as ministry of education.

Abstract
Background & Objectives: Prevalence of cytomegalovirus (CMV) infection varies is highly prevalent in different societies. CMV infection in susceptible patients is associated with serious morbidity and a high mortality and is a matter of concern for blood bank professionals and blood transfusion recipients, especially in cases of transfusions to neonates and immunocompromised patients. Thus, the present study aimed to determine the prevalence rate of anti-CMV antibodies among the blood donors of Mashhad Blood Transfusion Center.
Methods: This seroepidemiology study carried out on 1008 samples from blood donors in Mashhad Blood Transfusion Center and the prevalence rate of anti-CMV antibodies (IgM, IgG) was estimated by ELISA method in the samples
Results: Out Of 1008 serum samples from donors, 1000 persons (99.2%) had anti-CMV IgG and 16 donors (1.6%) had anti-CMV IgM in their sera. Eight (8) persons had no anti-CMV IgG and IgM in their sera.
Conclusion: The high rate of prevalence of CMV in this study region indicating blood component screening strategies for blood transfusions require particular attention among healthcare professionals as part of the actions for prevention and reduction of primary infections caused by CMV.

Abstract
Background and Objectives: Acute gastroenteritis is mainly caused by some viruses and often NoVs. In January 2014, an outbreak of gastroenteritis occurred in Pardis City, in Tehran and that made 5064 patients visit health centers. The purpose of this study was to investigate the epidemiology of the disease in this region.
Methods: This cross sectional study was done to evaluate the outbreak of gastroenteritis in Pardis City in January 2014. In this outbreak, the data of 1150 out of 5064 patient was collected by health centers. The inclusion criterion was residing in the location for at least ten days before its occurrence. The exclusion criterion was incomplete recorded data. A number of 126 human samples underwent laboratory investigation. The data collection tool was was line listings and data analysis was done with Excel 2010 and SPSS21 software.
Results: female and male patients comprised 57.8 and 42.2% of the study population and 59.7% of the subjects were under 27 years of age. The most prominent symptoms were vomiting (94.9%), diarrhea (37.7%), abdominal pain (18.8%), and fever (0.6%). The results showed that bacterial contamination, parasites, serologic tests for hepatitis E (IgM-HEV) and hepatitis A (IgM-HAV) and RT-PCR for hepatitis E and A were negative but 6 out of 9 fecal samples were positive for NoVs using molecular RT-PCR.
Conclusion: The results revealed the role of NoVs in Pardis City in 2014. Moreover, clinical and epidemiological characteristics of the population, season, and the environment of this diagnosis were confirmed.

Abstract
Background and Objectives: Hirschsprung's disease is one of the congenital movement disorders of the bowel whose accurate and timely diagnosis in childhood is important. The disease occurs due to lack of ganglion cells in the distal part of the digestive system and leads to functional obstruction of the colon. Recently, by the frozen section method, the diagnosis and treatment of the disease is possible through one-stage surgery with fewer complications and lower costs without the need for early colostomy. The aim of this study was to evaluate the validity of frozen section in Hirschsprung's disease.
Methods: this retrospective study was done on 406 frozen section results obtained from patients admitted to Mofid Hospital during 1389-90. We evaluated the frequency of “positive” and “negative” samples and compared them with the results of the permanent section. Moreover, the validity, sensitivity, specificity, and positive and negative predictive value of frozen section were calculated.
Results: After examining 406 frozen section samples and comparison with the results of permanent section, the results were consistent for both methods in 369 cases (90.89%) while the results were inconsistent in 37 cases (9.11%). Frozen section showed 7 (1.7%) false negative and 30 false positive (7.3%) cases. The sensitivity, specificity, positive predictive value, and negative predictive value of frozen section was 94.44%, 89.29%, 79.87%, and 97.28%, respectively.
Conclusion: Frozen section is a good tool for screening and diagnosis. Its power to rule out the disease is rather more than its power to confirm its presence. so it is capable of ruling out the disease in 97% and confirming its presence in 80% of the cases.

Abstract
Background and Objectives: Hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infections could affect the prognosis of disease in patients with human immunodeficiency virus (HIV)/AIDS. We aimed to determine HBV/HCV co-infection in HIV-positive individuals; and to compare the characteristics of different subgroups of HIV/HBV/HCV.
Methods: In this cross-sectional study, 908 of 2134 newly-registered HIV-positive individuals in the Iranian Ministry of Health in 2016 were recruited. Participants were divided into four subgroups (HBV-/HCV-, HBV+/HCV-, HBV-/HCV+, and HBV+/HCV+). Demographic data and HIV transmission routes were compared between subgroups.
Results: Among908 participants, 505 (60.6%) were HBV-/HCV-, 20 (2.2%) were HBV+/HCV-, 318 (35%) were HBV-/HCV+, and 20 (2.2%) were HBV+/HCV+. Mean age of participants was 36.9 years; 67% were male and 47% were married. The commonest high-risk behaviors were unsafe sex (43.5%) and IV drug-abuse (34.4%). There was no statistically significant difference between the mean ages of subgroups. All HBV+/HCV+ ,92% of HBV-/HCV+, 50% of HBV+/HCV- and 52% of HBV-/HCV- were men and the difference between groups was statistically significant (p-value: <0.001). Seventy four percent of HBV-/HCV+ and 80% of HBV+/HCV+ reported IV drug-abuse. Thirty percent of HBV-/HCV- and 40% of HBV+/HCV- were spouse of HIV-positive or high-risk individuals.
Conclusion: More than 30% of newly registered HIV-positive individuals in the Iranian Ministry of Health in 2016 were co-infected with either HBV or HCV. Frequency of men, marital status and high-risk behaviors were different in various subgroups.

Abstract
Background and Objectives: The Problematic Internet Use Questionnaire (PIUQ) is a scale for evaluating the adverse effects of high Internet usage. It was adopted into Persian in a previous study. The factorial structure of the adopted version was different from the original English version. The purpose of this study was to determine the factorial structure of the Persian version of the Problematic Internet Use Questionnaire.
Methods: In this methodologic study, sampling was carried out in students of Iran University of Medical Sciences, University of Tehran, and Sharif University of Science and Technology. A total of 428 students completed the Problematic Internet Use Questionnaire. Exploratory factor analysis was performed using SPSS. Confirmatory factor analysis was carried out using AMOS. The reliability of the Scale was determined using Cronbach’s alpha coefficient (α=0.89).
Results: Exploratory factor analysis showed four factors including online preoccupation, adverse effects, social interactions, and excessive use. The mean ± SD of the domains was 2.12±0.81, 2.01±0.86, 2.18±0.85 and 2.39±0.97 for online preoccupation, adverse effects, social interactions, and excessive use, respectively.
Conclusion: The exploratory and confirmatory factor analysis showed that the Persian version of the Problematic Internet Use Questionnaire had a relatively similar structure with the English version. One dimension of the questionnaire was split to two new dimensions. This questionnaire can be a useful tool for measuring problematic behaviors related to the excessive use of the Internet.
