Introduction: The reported 12 months prevalence of low back pain in nurses ranges from 43% to 76%. In most researches physical factors were only a part of high prevalence of low back pain in nurses. This study was conducted to determine the association between occupational stress and low back pain in nurses. Materials and Methods: In this case-control study, 80 nurses as case group and 80 nurses as control group were selected via convenience sampling. Case group were defined as those subjects who had experienced low back pain in the last 12 months. Control group were defined as those subjects who had not experienced low back pain in the last 12 months. A questionnaire was used for data collection which consistsed of 3 sections: demographic information, history of low back pain and occupational stress. Data was analyzed using paired T, Mann-Whitney, and Chi-square tests, correlation coefficient and one way ANOVA Results: Results indicated that, there was an association between low back pain and occupational stress (p<0/01).Also an association existed between low back pain and working hours per month (p<0/05). Statistical tests showed no significant difference between the two groups in terms of age, gender, marital status, number of childbirth, number of pregnancy, smoking, sport, work shift, number of years spent in the hospital (nursing experience). Conclusion: Results indicated that occupational stress in case group was more than control group. Since there was not any significant difference between other factors and low back pain, it can be concluded that there is an association between low back pain and occupational stress.

Introduction: The use of complementary and alternative therapy is increasing and touch is one of them but several studies have indicated that premature neonates hospitalized in neonatal intensive care unit receive very little touch. The purpose of this research was to determine the effect of touch on arterial blood oxygen saturation in neonates with respiratory distress syndrome. Materials and Methods: This is a clinical trial with repeated measures that was performed on 37 neonates with respiratory distress syndrome. An information record form was used for data collection. The information record form was consisted of two parts: demographic information and a table for recording oxygen saturations. Oxygen saturation was measured by Nelkor pulse oxy meter. Information was collected in 3 sequential days. Arterial blood oxygen saturation was controlled 5 minutes before touch, then samples undergone 5 minutes touch and then in 5 and 15 minute intervals arterial blood oxygen saturation was controlled again. Data was analyzed using repeated measure ANOVA. Results: Findings showed that in the first day, arterial blood oxygen saturation in 5 minutes before, and 5 and 15 minutes after touch were 95/67, 95/91, 96 respectively. In second day, arterial blood and oxygen saturation in 5 minutes before, and 5 and 15 minutes after touch were 95/72, 96/05, 96/08 respectively. In third day, arterial blood oxygen saturation in 5 minutes before, and 5 and 15 minutes after touch were 95/75, 96/16, 96/13 respectively. Arterial blood oxygen saturation in 5 and 15 minutes after touch were more than 5 minutes before touch in each 3 day(p<0.01). But there was no significant difference between 5 and 15 minutes after touch. Data analysis also showed no significant difference comparing arterial blood oxygen saturation in the 3 days. Conclusion: Findings suggested that premature neonates physiologically responded to touch. Nurses working in NICUs must be educated about the importance of touch in providing care for these neonates. Findings showed that touch is useful for premature neonates and this fact can be a start point for other investigations.

Introduction: Urinary tract infection is one of the most common nosocomial infections that mainly occur after instrumentation in urinary tract, particularly after urinary catheterization. This study was conducted to assess disinfection's effects of meatus and urinary catheter with 10% Povidone Iodine ointment on incidence of bacteriuria in hospitalized patients of neurological unit of Shohadaye Tajrish hospital in iran. Methods and Materials: This study , is a randomized clinical trail which is done on Seventy stroke's patients that were catheterized by urologic expert's selected on convenience sampling and randomly divided to tow groups (Experimental group: 35 patients, Control group: 35 patients). In the experimental group, meatus and catheter drainage tube junction were disinfected daily and spigot was disinfected tow times a day by PVP10% ointment. In the control group the cares were done by normal saline. In days: 2,5,8,11,14 a urine sample was sent to lab for culture. The maximum period of study was 14 days. Results: Incidence of bacteriuria in experimental and control groups were 20% and 42.9%, respectively. Relative risk was 2.14. In patients with positive urine cultures: puri was 85.7% in experimental group and 86.6% in control group. Clinical symptoms of UTI were seen in 28.6% in experimental group and 33.3% in control group. Conclusion: This study showed that application of povidone-iodine 10% ointment for disinfection meatus and catheter drainage tube junction is effective to prevent catheter-associated urinary tract infection in male patients.

Abstract Background: Medication errors in healthcare professionals can threat the health of patient seriously. The purpose of this study is to investigate the comments of nursing educators about reasons and reduction strategies of medication errors in nursing students. Materials and Methods: This descriptive study was done in 2008. Statistical population was included educators of nursing students in Arak nursing and midwifery school through census method, 22 nursing educators were studied. For data gathering, a self- made questionnaire including two sections of demographic information and questions about reasons and reduction strategies of medication errors in nursing students, was used. Results: Respectively 50% and 100% of nursing educators have observed at least one occurred and were occurring medication errors. The most common causes of medication errors were lake of pharmacological information, poor drug calculation skills and illegible medication orders in drug card. Conclusion: The rate of medication errors in nursing students was high. It seems some causes like lake of pharmacological information and drug calculation, have associate with their education. Using these results, we can find the weaknesses of student or the educational system and resolve them
