Introduction: surgery is a stressful experience for patients and most surgical patients have some degree of anxiety. The purpose of this study was to investigate the effect of a relaxation technique in addition to narcotic analgesic on health promotion in surgical patients. Methods: in this clinical trial, 70 patients who were candidates for elective upper and lower gastrointestinal system surgery were selected. They were randomly divided into two groups: case (morphine 0.15 mg/kg daily in divided doses and progressive muscle relaxation (PMR)) and control (morphine 0.15 mg/kg daily in divided doses). In each patient, the PMR intervention would be performed for 20 minutes every 6 hours for 2 days until 2 hours before the operation. Vital signs and anxiety were evaluated in the two groups after surgery. Data were analysed by t-test, analysis of variance, and chi-square test. Results: a statistically significant difference was seen in vital signs, pain and anxiety between the two groups. However, there was also a significant difference between them in terms of economic status and insurance coverage, which could have had an effect on stress and anxiety. Conclusion: PMR could increase the pain threshold, stress and anxiety tolerance and adaptation level in surgical patients. Therefore, using this technique could be an appropriate way to reduce analgesic drug consumption.
Coronavirus disease (COVID-19) initiates several life-threatening complications including coagulopathies with a unique characteristic that made this problem challenging. Here we presented 4 cases of RT-PCR positive patients that have experienced deadly intraperitoneal hemorrhage with fourth WHO Bleeding Grade after overcoming their respiratory phase. COVID-19 could induce several coagulopathies with different features that besides iatrogenic interventions increases its mortality and morbidity due to lack of clinical evidence based on well-designed randomized clinical trials on anticoagulation therapies (AT) and administration of varieties of newly approved and non-approved medicines. This report showed the urgent need for investigation on the pathophysiology of COVID-19-associated coagulopathy esp. in hemorrhagic events which are needed to make the best therapeutic decision.
Background: There is no specific cause of low back pain for eighty- five percent of cases and they were classified as non-specific low back pain. In this study, the size and symmetry of the lumbar multifidus muscles in industrial workers with non-specific chronic low back pain and healthy workers were investigated. Materials and Methods: In a cross-sectional comparative study, sixty industrial workers were divided into two groups of chronic low back pain and healthy, based on medical history and physical test. Roland-Morris Low Back Pain Questionnaire were filled by the group with chronic low back pain and dimensions of lumbar multifidus muscles in the L4-L5 level were measured by ultrasonography and the atrophy and asymmetry of two sides were examined. Results: Average size of right muscle in patients ranged between 2.5 and 4.3 CM? Inch? with average of 3.6 ± 0.43 and size of left muscle was in the range of 2.8 to 4.7 with the average of 3.9 ± 0.46. Size of right Muscle in healthy group was between 3.6 and 4.9 with the average of 4.3 ± 0.4 and left muscle size in healthy group was in the range of 3.9 to 5.09 and average of 4.4 ± 0.42 (p< 0.001). The proportion of symmetry, in the patient group was less (0.9) compared to those with no symptoms (0.95) (p<0.001). Conclusion: This study showed that the size of the multifidus muscle in patients with chronic non-specific low back pain at L4-L5 level was smaller compared to without back pain subjects on the basis of the average size of right and left muscle. Besides, in the patient group, muscle size in one side was smaller than the other side, in a way that there was a clearly and significantly asymmetry in muscle size between both sides.in addition, difference between size was observed between the two left and right waist size in the healthy group.
Background and Aim: Uterine anatomical pathologies play important roles in causing female infertility. This study was conducted to survey the efficiency of hysteroscopy and vaginal sonography in detecting the intrauterine pathologies in infertile women. Methods: This cross-sectional study was conducted on all the infertile women referring to the Endometriosis Research Center between December 22, 2013 and August 22, 2015. Forty five women were recruited and the data on the examinations of uterine lesions were analyzed by transvaginal sonography (TVS), hysteroscopy, and pathology as the standard test. Data analysis was conducted by SPSSv16 using t-test and Mann-Whitney test, and the sensitivity and specificity were measured with reference to the standard test. Findings: For diagnosing polyp, endometrial hyperplasia, and myoma, TVS showed the 75%, 25%, and 85.71% sensitivity, respectively, and specificity of 92.30%, 92.30%, and 56.97% respectively. For them, hysteroscopy showed the 60%, 75%, and 75.71% sensitivity respectively, and specificity of 71.65%, 30.92%, and 56.97% respectively. Conclusion: According to the findings of this study, the sensitivity of TVS and hysteroscopic findings in diagnosing uterine pathologies is relatively high, but the sensitivity of TVS was low to diagnosis of endometrial hyperplasia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
