Abstract
Background & Objectives: Early detection can improve the outcome of visual impairment in children, and one method for early detection could be screening of pre-school children with visual acuity tests. The aim of this study was to determine the validity of these tests when they are used on children entering grade school.
Methods: For this cross-sectional study we drew 39 random clusters, comprising a total of 5721 school children. We then used 2158 student files to extract data on tests of vision performed by school health officers and compared these data with data generated by optometrists. Measurement of uncorrected visual acuity was done with the E Chart by both teachers and optometrists.
Results: The sensitivity and specificity of teacher-administered tests were 25.0% and 96.6%, yielding positive and negative predictive values of 13.4% and 98.4%, respectively. Sensitivity and specificity rates did not show any significant difference between male and female populations (P=0.356, P=0.258), but the difference between specificity in urban and rural areas was significant (P<0.001).
Conclusions: Screening tests for visual impairment did not attain the desired level of sensitivity or specificity for case detection in school children. More accurate procedures are required to minimize the number of false negative results.

Abstract
Background & objectives: Urinary Tract Infection (UTI) which unfortunately has no clear symptoms in many cases is the second prevalent infection among children after respiratory infection. This study carried out in order to determine the frequency of asymptomatic UTI among elementary school girls in one of Tehran’s suburbs
(Mahalat town).
Methods: In a cross sectional study, all elementary school girls (n=1216) of study town who were between 6 to 11 years of age, were screened with urinary strip dipstick test method and urinary culture test was carried out on persons who had urinary PH> 7 and positive nitrite, as cases were doubtful to UTI. Afterwards, positive culture cases were referred to a urology specialist for investigating symptoms and, asymptomatic UTI samples were recognized.
Results: Among 67 students who were doubtful to UTI (based on dipstick strip test), 14 cases out of (%1.15 from 1216 samples), that is %1.15, were suffering from UTI. Regarding symptoms of UTI, just %35.72 of infected persons possessed at least one symptom of UTI and most of them that is %64.28, possessed asymptomatic UTI and the percentage of these people were obtained %0.74 for whole screened statistical society.
Conclusions: Since asymptomatic UTI and its probable complications might be recurrent, screening in dipstick method which is effective, rapid and inexpensive is completely necessary to improve the level of public health especially for children.

Abstract
Background and Objectives: Colorectal cancer is the third most common cancer in men and the second most common cancer in women in the world. The colorectal cancer screening program was conducted in Iran as a pilot in the late 2010 with the aim of reducing the burden of colorectal cancer. The aim of this study was to evaluate the colorectal cancer screening program in Iran.
Methods: This cross-sectional study was conducted on data from the pilot colorectal cancer screening programs. First, the indicators of the colorectal cancer screening program were determined through a comprehensive review of scientific databases, interviews with experts and implementation of pilot evaluation. Then, the indicators were calculated through descriptive analysis using SPSS version 18.
Results: The indicators and their values were as follows: coverage rate 33.04%, participation rate 53.3%, percentage of consulted people 99.6%, percentage of blood samples 37%, percentage of colonoscopy 54.8%, cancer detection rate 2.7%, and polyp detection rate 18.1%. Among people who gave blood samples 1.6% had familial adenomatous polyposis (FAP) syndrome, 43.06% had hereditary no polyposis colorectal cancer (HNPCC) syndrome, and 29% were sporadic cases.
Conclusion: The screening program in Iran has differences with other countries which have affected the indicators.

Abstract
Background and Objectives: People with high risk alcohol use disorders are influenced by behaviors that have devastating consequences for them and those around them. The main objective for alcohol screening is to identify people with alcohol use disorders, or people who are at high risk for progression to these disorders. Several screening tools have been designed for this purpose. The aim of this study was to introduce and review important screening tools for identification of alcohol use disorders and problems in the world.
Methods: In this narrative review study, we searched the Web of Science (ISI), PubMed, and Scopus databases using Alcohol, Tools or Instruments, Test, Problem, Use and Use disorder as keywords for finding screening tools for identification of alcohol use problems and disorders. Finally, 10 instruments were introduced.
Results: The most common screening tools for identification of alcohol use disorders and problems were Alcohol Use Disorder Identification Test (AUDIT), CAGE, Michigan Alcoholism Screening Test (MAST), as well as T-ACE and TWEAK that are specifically used for evaluation of alcohol consumption in pregnant women. The short forms of the AUDIT, RAPS, POSIT, and CRAFFT are other tests for alcohol consumption.
Conclusion: Several screening tools have been designed for identification of alcohol use disorders and problems; therefore, n appropriate screening test should be selected and implemented with regards to the purpose of screening, research questions, and study population.

Abstract
Background and Objectives: Cervical cancer is one of the five most common cancers in Iranian women. Considering the impact of HIV on cervical cancer and the low rate of cervical cancer screening in HIV positive women, this study was conducted to review the barriers to cervical cancer screening in HIV positive women.
Methods: In this systematic review, data were retrieved from Magiran, SID, Irandoc, Prequest, OVID, ScienceDirect, PubMed, Web of Science and Scupos databases from January 2000 to January 2018. The following keywords and their combination were used: cervical cancer screening, Pap smear, HIV-positive women, and barriers. The NOS (Newcastle-Ottawa Scale) checklist was used to evaluate the quality of the selected articles and the articles that scored more than six were included in the study.
Results: From 145 selected articles, 21 were included in the review based on the inclusion criteria. The most common reported screening barriers were the costs of test, lack of awareness, low education level, younger age, lack of information about screening centers, and fear of sampling.
Conclusion: Considering the barriers to cervical cancer screening, increasing the level of awareness of the HIV-positive women, preparing free Pap smear services, and providing easier access to health centers for this high risk group could lead to early detection of cervical cancer.
