They completed Internet Addiction Questionnaire and NEO test. Population samples were divided into two groups: addicted and non-addicted. Their personality styles were determined based on two dimensions: Neuroticism and extroversion. Then data were analyzed using logistic regression model by SPSS software. According to this study 86% of users had internet addiction [56% mild, 28% moderate and 2% severe] and 14% did not. Twelve personality styles in terms of neuroticism and extroversion were entered in the logistic regression statistical models, internet addiction predictor styles included: stress vulnerability [p < 0.0001], and impulsively [p<0.05], Being active [p<0.05] and excitement policy [P < 0.05]. Also, there is a significant relationship between internet addiction, teen aging [P<0.03] and being unemployed [P < 0.0001]. According to the results of this study, it seems that personality styles are suitable predictors for vulnerability for internet addiction. The results suggest that internet users' character assessment, and identifying individuals at risk, can help prevent internet addiction

To assess a multi-component intervention to prevent post operative delirium after open-heart surgery. This is an experimental-analytic study which assessed 32 patients 45 to 70 years of age after open-heart surgery in to 16 member groups [case and control]. From second days after operation until three days later, by 6 risk factors: cognitive visual and auditory impairment immobility, dehydration and sleep deprivation were assessed and a standard protocol was used for case group. Incidence of delirium was determined by clinical interview; based on DSM-IV-TR; twice a day [morning and evening]. Result were analyzed by t-test and S- plus. The median of total number of risk factors and immobility in case group had a significant reduction in comparison to control group. There were trends towards reduction in other risk factors and incidence of delirium. Primary prevention of delirium is probably the most effective treatment strategy

Main educational stressors and their relationship with general health of the medical residents

In the age of information and technology application, troublesome regulations and traditional procedures for medical education may cause serious stresses and be a threat to the general health [GH] of the students of medicine. To determine the relationship between educational stressors and the general health of residents studying at the Ahwaz Jundishapour University of Medical Sciences [AJUMS]. In this cross sectional study, the study group was consisted of 114 cooperative residents [69% of all residents in the hospital], who were being trained in a variety of different specialties. The instruments used were the Educational Stressors Questionnaire, including 45 four-choice items and a General Health Questionnaire. When the questionnaires were completed, the results were analyzed through Pierson Correlation Coefficient using the SPSS. The residents mentioned their educational stressors as follows: lack of an arranged curriculum, troublesome educational regulations, deficient educational instruments, and inadequate clinical instruction. Of all the subjects, 43 [37.6%] appeared to have problems in GH, and significantly positive correlation [p<0.01] was observed between educational stressors with all of the following parameters: GH, somatic problems, anxiety, and social dysfunction. As it appeared, educational stressors can be risk factors for the students' GH, which may be followed by reduced interest, low educational performance, and failure to achieve competency in diagnostic procedures and treatment.

How to decrease the emotional impact of cadaver dissection in medical students

Teaching anatomy is based on cadaver dissection. Working with cadavers, whether through active dissection or by examination of prosected specimens, constitutes a potential stressor in medical education. To reduce the anxiety of the medical students by mentally preparing them before going to the dissection room. The questionnaires were distributed among 68 medical students. The pre-dissection questionnaire comprised questions related to demographic data and the first encounter with a cadaver. The students were randomly divided into experimental and control groups. The experimental group was prepared psychologically prior to dissection, but the control group entered the dissection room without any preparation. After the first dissection class, all students were surveyed by the second questionnaire which surveyed physical and cognitive symptoms of anxiety, resulting from exposure to the dissection room at the first visit and six weeks later. There was a significant difference [p<.05] in the rate of anxiety between experimental and control group in the initial visit. The difference in the rate of anxiety between the first exposure and six weeks later was significant in control group [p<.008], while it was not significant in the experimental group. The initial preparation could relatively reduce the rate of stress, so that the experimental group experienced less emotional effects during dissection compared to control group
