Aims: FATIGUE is a common complaint and debilitating symptom in dialysis patients that has a considerable effect on quality of life and well being. The purpose of this study was measurement of FATIGUE and its related factors in patients with CHRONIC renal failure receiving hemodialysis.Methods: This descriptive correlation study performed in one of the Medical Universities of Tehran in 2009. 56 hemodialysis patients were selected by simple achievable sampling method. Data was collected by FATIGUE severity scale (FSS) and personal information questionnaires included demographic, disease information and paraclinical findings. Data was analyzed by SPSS 14 software and paired T-test and ANOVA.Results: The FATIGUE score mean of the patients was 5.1. Women, widow and people without job reported higher FATIGUE. By reducing the level of education and income and increasing the age, dialysis history and risk of CHRONIC renal failure the FATIGUE increased; these differences were significant only in terms of gender, income and history of CHRONIC renal failure. Mean of FATIGUE was insignificantly decreased in patients with hemoglobin equal to 12-14 gr/dl, systolic blood pressure >160 mmHg, urea <30 and creatinine 6-8 mgr⁄dl.Conclusion: Most hemodialysis patients suffer from high scores of FATIGUE. In order to improve patient care and promote patients quality of life, nurses should identify FATIGUE, high risk patients and strategies for decrease it.

Introductin: The advent of computers, visual display terminals and their capabilities have gradually resulted in an increase in their use and user population. The use of these devices have created new hazards for their operators, namely exposure to their electromagnetic field (EMF). Therefore,  assessment of this hazard and monitoring of operators' health is necessary. Material and Methods:This study was of a descriptive-analytical type. In this study, EMF around  80 monitors was measured at various distances in the of  Medical School of Hamadan University using HI-3603 survey meter. 50 computer operators wereselected as the case group  and another 61 were selected as the control group. The data concerning the signs of CHRONIC FATIGUE SYNDROME (CFS) were collected by use of questionnaires for both groups. The statistical test of t-test and χ2  were used for the analysis of the results. Results:Results indicated that in 97.7% and 27.5% of cases, at distances of 30cm and 50cm from the monitors respectively, the intensity of the magnetic field was greater than 20mA/m, respectively. In 28.7% and 10% of cases at distances of 30 cm and 50cm, the intensity of the electric field was greater than 2.5 V/m respectively. It was found that there was a relationship between the type and the life span of monitors (P<0.05). A comparison of the signs of CFS between the case and control groups indicated that there was a higher prevalence of lacrimation (P<0.001), headaches (P<0.001) and dizziness (P=0.002) in the case group. Conclusion: While operating a computor, it is recommended to keep a mininum distance of 60 cm away from it.
