Clinical and Radiographic Alterations in Bilateral Avascular Necrosis of the Femoral Head Following Laser Acupuncture: A Case Report

Introduction: Avascular necrosis (AVN) of the femoral head is an increasingly common cause of musculoskeletal disability with unknown etiology. Traumatic and non-traumatic factors can be effective in its occurrence. About 50% of cases are bilateral. The underlying treatment is prosthetic replacement surgical procedure.Case Presentation: We report a case of bilateral AVN of femoral heads who was a candidate for prosthetic replacement surgery but improved significantly, using laser acupuncture. The patient was a 55-year-old woman with a diagnosis of bilateral osteonecrosis of the femoral head for five years. As the patient declined the surgical option, laser acupuncture was started for pain control. Regarding the signs of bilateral femoral head recovery (according to the MRI scan criteria), a total of 3 courses of laser acupuncture (each course was 20 sessions) with 2 months intervals was performed. Ten acupuncture points: Li4, Li11, St36, SP6, LIV3, GB4, GB5, GB6, GB13, GB14, GB20, GB30, GB31, GB34, were irradiated bilaterally using red 650 nm laser, 100 mW, 1505 Hz frequency, duty cycle 50 3 J/point and near infrared 810 nm laser, 100 mW, 1705 Hz frequency, duty cycle 50 3 J/point, for 2 minutes. The patient received 3 laser therapy courses. During the first-course, laser therapy was done every other day to reduce pain. For the second and third courses, according to pain decrease, therapy was done every week.Results: The results of the MRI scans and x-ray studies show progressive regeneration of the right femoral head from VI to B II and of the left from V to C II (based on the standard table of Pennsylvania).Conclusion: It seems that this procedure may be mentioned in future research projects, especially in cases with high risks of surgery

Investigation of the knowledge and skill of proper consumption of fruit and vegetables among shahrekord adolescent girls

The life style is formed and stabilized in adolescence. Since consumption of fruits and vegetables may affect the risk of chronic diseases, their low consumption during adolescence is very important. Knowledge and skill is considered as one of the main determinants of this behavior. This study aimed to investigate the Knowledge and skill of proper consumption of fruit and vegetables among adolescent girls in Shahrekord, Iran. Materials and Methods: This study was a descriptive-analytic investigation conducted on high school girls in Shahrekord city during 2013 to 2014. 308 female students were selected randomly from 8 high schools and a researcher made questionnaire was used to collect the demographic, Knowledge and skill related data. Validity and reliability of the questionnaire was evaluated by internal consistency method (Cronbach's alpha = 0.70, Cronbach's alpha= 0.76), respectively. The collected data was analyzed by SPSS-21 software. Results: The mean age of students was 13.86 ± 1.3 years. There was no statistically significant association between consumption of fruit and vegetables and fathers' education level, mothers' job and parents' age. However, there was a significant association between fathers' job and adolescents' skill of fruit and vegetables consumption (P < 0.05). In addition, a significant association between mothers' education level and adolescents' knowledge and skill of fruit and vegetables consumption was observed (P < 0.05). There was a significant direct association between knowledge and skill (P=0.01 and r=082), so that adolescents with more knowledge, had a better skill as well. Conclusion: Considering the adolescents' low knowledge and skill in proper consumption of fruit and vegetables and also the direct association between knowledge and skill, it seems necessary to implement educational programs according to the health education and promotion theories and models, with contribution of parents and school personnel, to improve the knowledge and skill and empower adolescent girls in consumption of fruit and vegetables

Effect of Behavioral Intention Model-based Education on Decrease the Rate of Caesarean Delivery among Pregnant Women

Caesarean section is considered as a major surgery which is accompanied by several complications. The present study aimed to determine the effect of behavioral intention model-based educational intervention on reducing the caesarean section among pregnant women. The present interventional study was conducted on 100 primiparous women in the third trimester of pregnancy who were covered by the health and treatment centers of Fasa city, placed in Fars province, Iran. The subjects were selected through simple random sampling and divided into an intervention and a control group. After the pre-test, the intervention group underwent exclusive training based on the behavioral intention model. Then, both groups took part in the post-test and the data were analyzed using paired t-test, independent t-test, and chi-square tests. The results of the study revealed a significant difference between the two groups regarding knowledge, evaluation of the outcomes, attitude, and intention (P&lt;0.001). The results of the chi-square test also showed a significant difference between the two groups regarding their performance (P&lt;0.001). According to the results, the present intervention was effective in increasing the pregnant women’s knowledge, evaluation of outcomes, attitude and strengthening their intention as well as performance. Thus, this model and other systematic trainings are suggested to be used for pregnant women in order to decrease the rate of caesarean section.
