BackgroundPrimary dysmenorrhea is a common and sometimes disabling condition. In recent years, some studies aimed to improve the treatment of dysmenorrhea, and therefore, introduced several therapeutic measures. This study was designed to compare the analgesic effect of iron chip containing heat wrap with ibuprofen for the treatment of primary dysmenorrhea.MethodsIn this randomized (IRCT201107187038N2) controlled trial, 147 students (18–30 years old) with the diagnosis of primary dysmenorrhea were enrolled considering the CONSORT guideline. Screening for primary dysmenorrhea was done by a two-question screening tool. The participants were randomly assigned into one of the intervention groups (heat Patch and ibuprofen). Data regarding the severity and emotional impact of the pain were recorded by a shortened version of McGill Pain Questionnaire (SF-MPQ). Student's t test was used for statistical analysis.ResultsThe maximum and minimum pain severities were observed at 2 and 24 hours in both groups. The severity of sensual pain at 8, 12, and 24 hours was non-significantly less in the heat Patch group. There was also no significant difference between the groups regarding the emotional impact of pain at the first 2, 4, 8, 12 and 12 hours of menstruation.ConclusionsHeat patch containing Iron chip has comparable analgesic effects to ibuprofen and can possibly be used for primary dysmenorrhea.Trial registrationIRCT201107187038N2

Myocardial infarction causes limitations in the physical activity and perturbation of quality of life.The aim of this study was to evaluate the effect of eye movements desensitization and reprocessing (EMDR) on the quality of life of these patients. This study was conducted in two groups as the before and after while the effect of eye movements desensitization and reprocessing on the quality of life of the patients with Myocardial infarction. Sampling was done based on the purposive sampling. Patients were randomly divided into two experimental and control groups (30 patients in each group). Samples were assigned through randomized allocation. In the experimental group, the EMDR method was carried out on the patients in five 90-minute sessions over a two week period. In the control group no intervention was received. Data of Quality of life, pre-treatment, post-treatment were analyzed using SPSS. The results showed that the quality of life increase in all its dimensions of the experimental group, after performing the EMDR therapy significantly (P=0.001). Treatment what has already been stated, was effective on the quality of life in patients. Treatment team members can use this method as an effective intervention in order to improve the quality of life of their patients.

Background: One of the major topics related to the very long tunnels is dark hole effect. This is a common phenomenon caused by the sunlight reflected from the surroundings of the tunnel to the eyes of drivers and the lack of sufficient light at the tunnels' entrance, which decreases the contrast of barriers inside the tunnel and also makes it difficult to see potential obstacles at the entrance. The result is an increased risk of traffic accidents in these tunnels. Therefore, the aim of this research is to subjectively assessment the safe rate of lighting in one of the very long tunnels located in the province of Ilam. Methods: To subject evaluation the safe rate of lighting at the tunnel entrances, two parameters of the average luminance of tunnel entrance and equivalent luminance are required. In this study, Luminancemeter device model S3 was used to measure the average luminance of tunnel entrance. Then, to calculate the equivalent luminance, a YASHICA108 camera with a 35 mm lens was photographed at a distance between the tunnel entrance and a safe stopping point, and then the Holliday polar diagram was used to calculate equivalent luminance (accordance with the standard CIE88-2004). Results: In this study, the average luminance at tunnel's entrance was equal to 17 , the luminance was equal to 127.5  Using the ADRENAL equation, the quality of lightening at the tunnel entrance was less than 1. Conclusion: Comparison of the results obtained from the healthy and safety rate of lighting levels at the tunnel's entrance with the De Boer mental scale indicated that a dark hole effect occurs at the entrance of the tunnel under investigation and the light sources installed at the entrance of this tunnel did not have the sufficient ability to inhibit the dark hole effect.
