@article{ author = {EbrahimiFakhar, Hamid rez}, title = {The outcome of patients hospitalized with severe head injury in Vali-asr Hospital according to Glascow Coma Scale in 2005-06}, abstract ={Abstract Background: Information on patients' physical and mental disabilities, their lifestyle during rehabilitation period and probably their death due to severe head injury in acute phases is too insufficient and in some cases, it does not exist at all. The aim of this study is to determine the outcome of patients who were hospitalized in Vali-asr Hospital of Arak according to Glascow Coma Scale (GOS). Materials and Methods: In this cross-sectional retrospective study, using the patients' files in Vali-asr Hospital which is situated in Arak, the patients, who had been hospitalized with severe head injury during 2005-06, were identified. Based on the information existing in their files or visiting them individually in their place of living, 24 months after their release from hospital, their physical and mental performances were examined according to Glascow Outcome Scale (GOS) and were compared to the time of their release from the hospital. Results: Out of 130 patients, 55.4% died within 2 years after the hospitalization period. Among those dead, 32% died in the first 24 hours of hospitalization, 44.4% after the first 24 hours and before release from the hospital and 23.6% after being released from the hospital. The mean of GOS score, from the time of release until 2 years after that, improved from 2.7 to 3.3.

During pregnancy, vitamin A is extremely essential for the development of fetus and its lack, insufficiency or excess can result in embryonic malformations. This study investigated the synergetic effects of vitamin A and extremely low frequency electromagnetic fields on the development of embryo skin in Balb/C mice. Materials and Methods: This study was experimental in nature. Eighteen pregnant mice were divided into control, sham-exposed and experimental groups. The mice in the experimental group were given an intra-peritoneal injection of 15000 IU/kg vitamin A on the 10.5th day of gestation and were, then, exposed to a 50Hz electromagnetic field 4 hours a day from 10 through 12th day of gestation. The animals were dissected and investigated morphologically and histologically on 17.5th day of gestation. Results: The results showed an increase in the mean weight of fetuses in the experimental group in comparison to the sham- exposed group (p<0.05). Also, Crown-Rump of fetuses in the experimental group increased in comparison to those in the sham- exposed group (p<0.001). Epidermis thickness increased significantly in experimental group in comparison to sham- exposed (p<0.05), while the average number of basal, spinous cells and hair follicles decreased significantly in the experimental group compared to the sham- exposed (p<0.001).

This study compares two eras of pacing therapy including pacemaker implantation by cardiac surgeons and pacemaker set-up by a group of cardiologists in Shahid Rajaee Hospital in Tehran. Materials and Methods: In this cross-sectional study, we compared the existing data from all pacemaker implantations in the first half of 1999 (surgical era, era 1) to that of the first half of 2001 (cardiologists era, era 2). Results: During era 1, a total 114 pacemakers (46.5% male, mean age 63.3 ±18.4) and during era 2, 299 pacemakers (63.9% male, mean age 63.9±18.2) had been implanted. Indications for implantation were nearly similar, with AV block as the most common reason in 21.9% and 19.1% of implantations in eras 1 and 2, respectively. Single chamber pacemakers comprised 86% of implantations during era 1 compared to 54% during era 2 (p<0.01). The mean duration of admission was 18 days during era 1 while it was 10 days during era 2. Pacemaker malfunctions were detected following 7.9% of implantations in era 1 compared to 0.3% of cases in era 2 (p<0.01).

Ischemia/reperfusion injury increases iNOS expression in the renal tissue. Inhibition of iNOS expression and its activity can ameliorate ischemia/reperfusion-induced renal injury. The aim of this study was to determine the role of iNOS on progression of renal functional disturbances over the immediate post-ischemic reperfusion period. Materials and Methods: In this experimental study, renal hemodynamic and excretory functions were evaluated in male Sprague-Dawley rats. First, a 30-min control clearance period was taken. Then following bilateral renal artery clamping for 30 minutes, four consecutive 30-min clearance periods were taken during reperfusion, while saline or L-NIL as a selective iNOS inhibitor was infused. In plasma and urine samples, Cr and sodium concentration levels were measured. Results: Renal ischemia for 30 minutes decreased glomerular filtration rate and urine osmolality during reperfusion and increased urine flow and sodium excretion. L-NIL did not change the glomerular filtration rate and urine osmolality prior to ischemia but it improved them during reperfusion and there were progressive increases in urine flow.

No superficial or deep infection or septic arthritis were seen in any of the patients in the two groups. Conclusion: Preoperative preparation of the knee with povidone iodine scrub is a safe method for prevention of infection and can be used instead of the common two-stage method of using povidone iodine scrub and then painting with aqueous povidone iodine since this can decrease the time and cost of surgery.}, Keywords = {Knee arthroscopy, Painting, Povidone iodine, Preoperative preparation of the site}, volume = {12}, Number = {4}, pages = {124-128}, publisher = {Arak University of Medical Sciences}, url = {http://jams.arakmu.ac.ir/article-1-298-en.html}, eprint = {http://jams.arakmu.ac.ir/article-1-298-en.pdf}, journal = {Journal of Arak University of Medical Sciences}, issn = {1735-5338}, eissn = {2008-644X}, year = {2010} } @article{ author = {Nouri, Maliheh and Merghatikhoie, Effat sadat}, title = {The impact of peer-based educational approaches on girls\' physical practice of pubertal health}, abstract ={Background: Adolescents, as a large age group in the world, face many physical, mental and social problems in their puberty period. Health education proper to their needs and through new educational methods is of great importance. This study mainly aims to examine the impact of peer education approaches on girls' performance regarding pubertal physical health. Materials and Methods: In this experimental study, through random sampling, 100 female pupils were divided into two groups of experimental (n=50) and control (n=50). The self-made questionnaire, employed in this study, was based on peer approach. After 1.5 months, the participants' performance was evaluated through the post-test and compared to the pre-test results for the two groups. Scoring was conducted out of 100 and the scores under 50 indicated weak performance, those between 50 and 75 showed an average performance while scores above 75 indicated good performance. Results: Peer based educational approaches improved adolescent girls physical health. Statistical tests also revealed a significant difference between the mean of awareness and practice score in the two groups (p<0.001). Conclusion: Peer education methods result in the empowerment of adolescents, the provision of opportunities for them to participate in activities, and the improvement of communication between mothers and their daughters.}, Keywords = {Educational approaches, Girls, Peer group, adolescent health}, volume = {12}, Number = {4}, pages = {129-135}, publisher = {Arak University of Medical Sciences}, url = {http://jams.arakmu.ac.ir/article-1-146-en.html}, eprint = {http://jams.arakmu.ac.ir/article-1-146-en.pdf}, journal = {Journal of Arak University of Medical Sciences}, issn = {1735-5338}, eissn = {2008-644X}, year = {2010} }
