Background: University entrance is accompanied by major changes in social relationship, rules, and expectations that lead to psychological disorders in susceptible students. The goal of this research is to study the anxiety rate in Iranian medical residents in 2010-2011. Methods: This study is a cross-sectional, descriptive study. It contains 370 medical residents from the 1 st year to the 4 th year of medical universities in Isfahan, Gilan, Zahedan, Sanandaj, and Kashan. The stratified sampling method proportionate to volume of participants is used in this study. The information is collected based on researchers′ questioners and Zung self-rating anxiety scale and analyzed with the use of spss software version 16, addition to descriptive and analytic tests (Pearson, one-way analysis of variance, t-test). Meaningful level is regarded as P ≤ 0.05. Results: The study showed that more than 92% of residents participated in the study did not demonstrate anxiety. Among 370 subjects 5.5% presented with mild symptoms of anxiety and no one had symptom of severe anxiety. A meaningful statistical relationship was observed between anxiety and sex, major of study and the city of study (P < 0.05). The results showed a positive meaningful relationship between the number of visits and the score of anxiety. On average the number of night floats were two in 1 week and the number of patient visit was 19 in the past 24 h. A meaningful statistical relationship between anxiety score and number of patient visits was observed. Conclusions: The anxiety rate in medical students in this study compared to the findings of previous studies reveled very low anxiety in medical residents. The low rate of anxiety could be attributed to the sense of job security and the hope for a better future among residents. The high percentage of anxiolytics abuse and absence of anxiety producing factors among residents in addition to inaccurate response to the questionnaire may all contribute to the low rate of anxiety in this study.

Background: Nowadays Medical equipment plays an important role in the treatment and in the medical education. Using outdated preventive maintenance (PM) system may cause problems in the cutting edge medical equipment, Nervous system disease′s equipment (In diagnosis and treatment) which are crucial for every medical center. Based on above facts we focused on nervous system treat units′ equipment and informed the supervisors and their colleagues about the latest equipment maintenance status and promoted methodical and correct method to be used for medical equipment maintenance. Methods: This research is an analytical descriptive and has been done on the base information from a particular time to past. We gathered our required information of 2009 from Alzahra Medical Center. We divided this research info 2 main phases. In the first phase, we picked out Neurosurgery and Neourology diseases medical equipment (diagnosis and therapy equipment) and in the second phase, we need to implement a methodical PM for every equipment. Results: Research has shown that there are 19nervous system equipment in Alzahra Medical center, categorized in diagnostic (13 pcs), therapeutic (4 pcs) and diagnostic-therapeutic (2 pcs). As we declare in methods part of this research, we categorized medical equipment in Food and Drug Administration (FDA) segmentation. Capital-scarce equipment: Magnetic resonance imaging, Eco Doppler, Kamalaarak ultrasonic surgical aspirator, Stereotactic, computed tomography-scan, euroendoscope/vital-scarce equipment: Coblation, Sonoco, vaterjet/scarce equipment: Transcranial color Doppler, electroencephalogram, electromyography, surgical microscope. Conclusions: Survey of application and preventive maintenance of neurology medical equipment in Isfahan Alzahra hospital show there is no P.M system. Implementing a complete P.M system for this medical center is crucial to preventing cause problems for these medical equipment and decreasing maintenance costs and gaining uptime. Researchers of this article have tried to provide PM, use of texts, web and experts.
