This double-blind randomized clinical trial was conducted on 75 students who lived in university accommodation of Islamic Azad university of Touyserkan، Iran in 2013. They were randomly divided into two reception groups of vitamin E (n=37) and placebo (n=38). Participants in reception group of vitamin E were use vitamin E capsules 400 unit/day in 7 premenstrual days for 2 month and students in placebo group used similar vitamin E capsules. Pain severity in before and after of vitamin E and placebo use was measured by Visual Analog Scale. Data analysis was carried out using SPSS software version?، Wilcoxon، t-test and Freidman tests. P value less than 0. 05 was considered significant. Muscular pain score in vitamin E group was 6. 98±1. 09 before vitamin use and 4. 14±1. 14، 2 months after vitamin use. Pain score in vitamin E group had a statistically significant difference in compared with placebo group (p<0. 001). Two groups were not significantly different in term of pain severity before taking vitamin E and placebo (p=0. 2). Vitamin E is effective on muscular pain reduction and due to having no side effects; it is recommended to be used instead of chemical drugs in muscular pain reduction in premenstrual syndrome.

A large number of womensuffered from the post episiotomy pain and the common method for pain relief is oral non-steroidal anti-inflammatory drugs. With considering the adverse effects of these drugs، the aim of present study was to compare the effects of lidocaine cream and mefenamic acid capsule on post episiotomy pain. This clinical trial was carried out in 2011 on 60 women with singleton pregnancy at 38-42 weeks of gestation who underwent episiotomy. Cases were randomly divided into both groups and received lidocaine cream and mefenamic acid capsule. Data were collected by questionnaire and Visual Analogue Scale. Pain intensity was compared with the first complaint of mother and 6، 12 and 24 hours after the delivery in both groups. Data were analyzed by SPSS software (version 16)، t-test and paired t-test. P value less than 0. 05 was considered significant. With the first complaint of women، the mean of pain intensity was 4. 92±1. 9 in lidocaine group and 4. 90±1. 5 in mefenamic acid group that was not significant (p=0. 20). Mean intensity of post episiotomy pain in two groups receiving lidocaine cream and mefenamic acid capsule were not significant at hours 6 (3. 26±1. 3 vs. 3. 10±1. 6، p=0. 05)، 12 (2. 26±1. 7 vs. 2. 86±1. 4، p=0. 36) and 24 (1. 46±1. 2 vs. 1. 49±1. 2، p=1) after delivery. The effects of lidocaine cream and mefenamic acid capsule in relief of post episiotomy pain were similar. With considering the side effects of mefenamic acid، lidocaine cream is an appropriate alternative drug in relief of post episiotomy pain.

In the present century، stress has become a common problem because of the increased stress factors and sedentary lifestyle. Considering that the impact of performance exercise on stress in midwives has not been assessed in Iran، this study was done to assess the impact of performance exercise on stress in midwives.

This randomized clinical trial was conducted in 2013 on 60 midwives working in selected health care centers of Mashhad، Iran. The intervention group did exercise training with intensity of 30 to 60% of maximum oxygen consumption for 45 minutes in 24 sessions. Subjects completed Codron Stress Assessment Questionnaire at the baseline and the end of study. Data were analyzed with SPSS software version 19 and independent t-test، paired t-test and chi-square test. P value less than 0. 05 was considered significant.

There were significant differences in intervention group at baseline and the end of the study in terms of job stress domains (44. 5±12. 5 vs. 36. 4±13. 7)، life health stress (39. 2±15. 5 vs. 29. 7±13. 6)، personal life stress (29. 5±12. 3 vs. 21. 2±11. 3)، individual personality stress (3. 6±0. 8 vs. 2. 1±1. 2) (p<0. 05). There was no significant differences in control group at baseline and the end of the study in terms of these 4 domains (p>0. 05).

Performance exercise program reduces the intensity of stress and it is recommended to be considered for midwives stress reduction.
