Background Burning mouth syndrome (BMS) is common conditions that affects menopause women, patients suffer from sever burning sensation. Up to now there is no definitive treatment for this disease. Present study was undertaken to evaluate the efficacy of low-level laser (LLL) in improving the symptoms of burning mouth syndrome. Material and Methods Twenty patients with BMS were enrolled in this study; they were divided in two groups randomly. In the laser group, in each patient, 10 areas on the oral mucosa were selected and underwent LLL irradiation at a wavelength of 630 nm, and a power of 30 mW for 10 seconds twice a week for 4 weeks. In the placebo group, silent/off laser therapy was carried out during the same period in the same areas. Burning sensation and quality of life were evaluated. Results Burning sensation severity and quality of life in the two groups after intervention were different significant statistically, (p= 0.004, p= 0.01 respectively) .Patients in laser group had better results. Conclusions It can be concluded that low level laser might decrease the intensity of burning mouth syndrome. Key words:Pain, low-level laser, burning mouth syndrome, oral mucosa.

The aim of this study was to determine the effectiveness of Mindfulness-Based Stress reduction (MBSR) on perceived pain intensity and quality of life in patients with chronic headache. Thus, forty patients based on the diagnosis of a neurologist and diagnostic criteria of the International Headache Society (IHS) for migraine and chronic tension-type headache were selected and randomly assigned to the intervention group and control group, respectively. The participants completed the Pain and quality of life (SF-36) questionnaire. The intervention group enrolled in an eight-week MBSR program that incorporated meditation and daily home practice, per week, session of 90-minutes. Results of covariance analysis with the elimination of the pre-test showed significantly improvement of pain and quality of life in the intervention group compared with the control group. The findings from this study revealed that MBSR can be used non-pharmacological intervention for improvement the quality of life and development of strategies to cope with pain in patients with chronic headache. And can be used in combination with other therapies such as pharmacotherapy.

Introduction:Premenstrual syndrome (PMS) refers to the cyclic occurrence of a set of disturbing physical, emotional or behavioral alterations that are of sufficient severity to interfere with interpersonal relations and routine life. Normal variations in gonadal estrogen and progesterone lead to biochemical reactions in the brain, resulting in PMS symptoms. This study aims to investigate the prevalence of PMS and PMDD signs among married women of fertile age (MWFA) based on the methods of birth control.Method and Materials:In a descriptive study, a number of 400 married women referring to 20 family healthcare clinics that use contraceptive methods were recruited and PMS questionnaire were administered to them.Results:From 400 subjects, 205 took oral contraceptive pills (hormonal methods of contraception) and 195 used other birth control methods (non-hormonal method). A number of 345 subjects (86.25%) at least experienced one PMS symptom and 55 subjects (13.75%) did not report any symptoms. Of those who use hormonal contraceptives (HCs), 182 (88.8%) reported PMS symptoms and 23(11.2) lacked any symptoms.Conclusion:About 86% of the subjects showed moderate to severe of PMS symptoms. Although using hormonal contraceptive method can theoretically reduce PMS symptoms, such effect was not observed in this study. The results of this research should be generalized with caution. Future studies are suggested.
