The effectiveness of agomelatine on headache severity and frequency in episodic migraine without aura; a parallel randomized controlled trial study.

BACKGROUND: Migraine is a headache disorder that affects public health and reduces the patient's quality of life. Preventive medication is necessary to prevent acute attacks and medication overuse headaches (MOH). Agomelatine is a melatonin antagonist. AIMS: This study aimed to determine the effectiveness of agomelatine on the severity and frequency of migraine attacks. METHODS: The study is a parallel randomized controlled trial with two groups of intervention and control. 400 patients were evaluated. Eligible individuals, including those with episodic migraine headaches without aura between the ages of 18 and 60 years who did not receive preventive treatment beforehand, were enrolled. Also, patients did not receive any specific medications for other diseases. Among these, 100 people met the inclusion criteria and entered the study. These subjects were randomly assigned to one of the two groups. The intervention group received 25 mg of agomelatine daily and the control group received B1. In this study, the effect of agomelatine on the frequency and severity of attacks, mean monthly migraine days (MMD), and migraine disability assessment (MIDAS), were assessed. The study was triple-blind and after three months, a post-test was performed. Data were analyzed using SPSS software. RESULTS: A total of 100 patients were randomly assigned to either intervention or control groups. The prescriber physician and the data collector did not know about the allocation of patients to groups. Before the intervention, there was no significant difference in the headache frequency per month (t=-0.182, df = 98, p = 0.85), mean MMD (p = 0.17), headache severity (p = 0.076), and MIDAS (p = 0.091). After the study, there was a significant difference between the two groups in terms of the headache frequency per month (p = 0.009), and mean of MMD (p = 0.025). There was also a significant difference between pretest and posttest in two groups in the headache severity (p < 0.001) and MIDAS (p < 0.001). CONCLUSION: Agomelatine can be used as a preventive medication for migraine without aura. It is suggested that agomelatine be studied in comparison with other preventive drugs for patients with migraine.

Evaluating and comparing critical thinking skills of residents of Tehran University of Medical Sciences.

BACKGROUND: Today's complexities and diversity in the clinical setting have revealed the need to pay attention to strengthening critical thinking (CT) skills. The present study aimed to evaluate and compare CT skills in the residents of the Tehran University of Medical Sciences. METHODS: This is a cross-sectional study. The study's statistical population included 284 residents in orthopedic, internal medicine, and surgery groups studying in the PGY1 to PGY4 years of residency. The data collection tool was the California Critical Thinking Skills Test (CCTST) form B. The collected data were entered into SPSS-16 software and analyzed using descriptive (mean and standard deviation) and inferential (one-way ANOVA) statistics. The significant level in all tests was considered at P < 0.05. RESULTS: 189 out of 284 residents completed and returned the questionnaire, and the response rate was 66%. The mean CT skill score of residents (M = 13.81, SD = 3.52) was lower than the optimal level (M = 17.1 SD = 5.0). Comparing the mean CT skill scores of the residents separately for the residency year revealed a significant decrease in CT scores in the 4 years. A significant difference was found between the CT skill scores in the three groups (internal medicine, general surgery, and orthopedic surgery). CONCLUSION: The CT skills of the residents of Tehran University of Medical Sciences were generally below the optimal level. The CT score of the residents show an increase in PGY2, but a decrease in PGY3 and PGY4. Due to the emphasis of accreditation institutions, the World Federation for Medical Education, and other international educational institutions on the importance of critical thinking, it is recommended to pay more attention to the factors related to the promotion and development of CT skills in residency programs.

Validation of the Persian Version of Spiritual Well-Being Questionnaires.

BACKGROUND: Spiritual well-being is an important issue in health sciences, hence the need for validated instruments to assess this aspect of health in the Iranian population. The aim of the current study was to determine the validity of the Persian versions of 2 most common measures of spiritual health (Spiritual Well-Being Questionnaire [SWBQ] or Spiritual Health and Life-Orientation Measure [SHALOM] and Spiritual Well-Being Scale [SWBS]). METHODS: This was a cross-sectional study via a convenience sampling method in Iran University of Medical Sciences with 170 participants aged above 18 years comprising students, teachers, and administrative staff and managers. The study was conducted from September 7, 2014 to September 20, 2015 in Tehran. Four questionnaires, namely the SWBQ, SWBS, General Health Questionnaire (GHQ-12), and Oxford Happiness Questionnaire (OHQ), were used. Statistical analysis was done using SPSS 18 and LISREL (version 8.2). Cronbach's alpha, intra-class correlation coefficient, Pearson correlation, and confirmatory factor analysis were employed to assess the validity and reliability of the questionnaires. RESULTS: Cronbach's alpha for the SWBQ and the SWBS was greater than 0.85. The repeatability of both questionnaires was between 0.88 and 0.98. The Pearson correlation for the SWBQ and the SWBS ranged from 0.33 to 0.53; and all the correlations were significant. The respondents who indicated a higher spiritual well-being also reported better general health and happiness. CONCLUSION: The Persian versions of the SWBS and the SWBQ have good reliability, repeatability, and validity to assess spiritual health in the Iranian population.

Determination of risk factors and cumulative effects of the maternal and neonatal risk factors in relation to preterm labor.

BACKGROUND: Preterm labor is the leading cause of neonatal morbidity and mortality this study aimed to determine single and combined effects of all risk factors in relation to preterm labor. METHODS: This was a case-control study that included patients from a teaching hospital affiliated to Tehran University of Medical Sciences. Women who came to this hospital for delivery were divided into two groups: 200 in preterm delivery (before 37 weeks) and 195 in term delivery (after 37 weeks). RESULTS: In all 409 pregnant women were delivered. 217 were preterm (group A) and 192 were term (group B). The mean age of mothers in group A was 30.04 ± 5.74 and the mean age of mothers in group B was 27.28 ± 5.90 (P < 0.001). The risk of preterm labor was 4.22 higher in mother with any risk factor before or during pregnancy (P < 0.001), it was 3.67 higher in mother with complication of pregnancy (P < 0.001) and it was 3.40 higher in neonate with any complication (P = 0.002) compared to mother without any risk factors. For each mother, we calculated risk score for preterm labor by counting the number of risk factors. The risk of preterm labor was significantly higher in mother with risk factors compared to those without any risk factors (P for trend = 0. 002). Mother with two risk factors had a 5.60 (P = 0.01) and mother with three or more risk factors had a 23.48 (P = 0. 001) times higher risk for preterm labor than those who did not have any risk factors. CONCLUSION: The screening and identification of mothers with risk factors for preterm delivery can increasing mother's attention and participation to better manage of these condition to have more safe pregnancy period.

Facial nerve paralysis in malignant otitis externa: comparison of the clinical and paraclinical findings.

BACKGROUND: Malignant otitis externa is an uncommon but critical challenging disease with some degree of cranial nerve involvement. AIM/OBJECTIVE: to examine the factors leading to facial paralysis in these patients and clarify indications for aggressive treatment in the group most at risk. MATERIAL AND METHODS: In a case-control study, demographic, clinical, laboratory, audiometric, imaging, and treatment characteristics of 139 patients in groups with and without facial paralysis were analysed. RESULTS: 45 patients (32.4%) had facial paralysis. Compared to patients without facial nerve involvement, patients with facial palsy had a higher rate of inflammatory markers (mean erythrocyte sedimentation rate on admission [67.71 vs 51.16 mm/h], and the average of total ESR [64.27 vs 54.46 mm/h], as well as the mean C-reactive protein [38.96 vs 27.53 mg/L]). Also, the involvement of the facial canal (p < .01) and nasopharyngeal space (p < .05) were related to the incidence of facial paralysis. CONCLUSION: Nasopharyngeal extension of the inflammation and facial nerve canal erosion might be useful as predictors of facial nerve dysfunction. The elevated erythrocyte sedimentation rate is correlated with the increased risk of facial paralysis, and aggressive medical management is more crucial. SIGNIFICANCE: Improvement in predicting the outcome of patients with malignant otitis externa.

Photorefractive keratectomy with mitomycin-C for the treatment of compound moderate myopia with astigmatism in buccal pemphigus vulgaris.

We report a case of controlled buccal pemphigus vulgaris with compound moderate myopia with astigmatism that was treated with photorefractive keratectomy with mitomycin-C (PRK+MMC) in both eyes. The preoperative manifest refraction was -6.50 sphere and -5.5 -0.75 x 20 in the right eye and left eye, respectively, with a best corrected visual acuity of 10/10 in both eyes. Seven months after surgery, the uncorrected visual acuity was 10/10 in both eyes. The manifest refraction was 0.75 sphere and 0.50 -0.75 x 120 in the right eye and left eye, respectively. Haze was not detected in the follow-up examinations. Reepithelialization was complete 5 days after surgery in both eyes. The results show that PRK+MMC for compound moderate myopia with astigmatism in a patient with controlled pemphigus vulgaris may be an effective and safe treatment.

Comparison of Bone Density of Distal Radius With Hip and Spine Using DXA.

Osteoporosis diagnosis is usually based on examination of the hip bone and vertebrae density; however, the radius bone has gained attention recently in terms of feasibility and accessibility as it is done by portable devices with proper precision. This study aims to compare hip and spine density with radius, knowing whether radius may be an appropriate alternative for osteoporosis diagnosis. 120 females who were referred to one Densitometry Center checked their skeletal status using a hologic unit for densitometry of spine, femoral neck, and one-third radius. The patients were divided into three groups of healthy, osteopenic and osteoporotic based on WHO's protocol. Concordance analysis was done to investigate the degree of similarity of diagnosis. In the study, there were 40, 41, and 39 individuals with normal, osteopenic, and osteoporotic bone densities, respectively which obtained from hip bone or vertebrae using the T-score criterion T-score of radius bone density has a direct linear relationship with these result. Osteoporosis diagnosis can be made based on radius densitometry.

Evaluation of the prophylactic use of mitomycin-C to inhibit haze formation after photorefractive keratectomy in high myopia: a prospective clinical study.

BACKGROUND: To study the effect of prophylactic application of mitomycin-C on haze formation in photorefractive keratectomy (PRK) for high myopia. METHODS: Fifty-four eyes of 28 myopic patients were enrolled in this prospective study. All eyes were operated by PRK followed by 0.02% mitomycin-C application for two minutes and washed with 20 ml normal saline afterwards. All eyes were examined thoroughly on the first 7 days and one month after surgery; 48 eyes (88.9%) at 3 and 6 months postoperatively. Hanna grading (in the scale of 0 to 4+) was used for assessment of corneal haze. RESULTS: The mean spherical equivalent refraction (SE) was -7.08 diopters (D) +/- 1.11 (SD) preoperatively. Six months after surgery, 37 eyes (77.1%) achieved an uncorrected visual acuity (UCVA) of 20/20 or better, all eyes had a UCVA of 20/40 or better and 45 (93.7%) eyes had an SE within +/- 1.00D. One month postoperatively, 2 eyes (3.7%) had grade 0.5+ of haze, while at 3 and 6 months after surgery no visited eye had haze at all. All eyes had a best corrected visual acuity (BCVA) of 20/40 or better and there were no lost lines in BCVA by 6 months after surgery. In spatial frequencies of 6 and 12 cycles per degree contrast sensitivity had decreased immediately after PRK and it had increased 1.5 lines by the 6th postoperative month compared to the preoperative data. CONCLUSIONS: The results show the efficacy of mitomycin-C in preventing corneal haze after treatment of high myopia with PRK. This method- PRK + mitomycin-C - can be considered an alternative treatment for myopic patients whose corneal thicknesses are inadequate for laser in situ keratomileusis (LASIK). However, the results should be confirmed in longer follow-ups.

Is Community-based Participatory Research (CBPR) Useful? A Systematic Review on Papers in a Decade.

BACKGROUND: Community-based participatory research (CBPR) has been applied by health researchers and practitioners to address health disparities and community empowerment for health promotion. Despite the growing popularity of CBPR projects, there has been little effort to synthesize the literature to evaluate CBPR projects. The present review attempts to identify appropriate elements that may contribute to the successful or unsuccessful interventions. METHODS: A systematic review was undertaken using evidence identified through searching electronic databases, web sites, and reference list checks. Predefined inclusion and exclusion criteria were assessed by reviewers. Levels of evidence, accounting for methodologic quality, were assessed for 3 types of CBPR approaches, including interventional, observational, and qualitative research design as well as CBPR elements through separate abstraction forms. Each included study was appraised with 2 quality grades, one for the elements of CBPR and one for research design. RESULTS: Of 14,222 identified articles, 403 included in the abstract review. Of these, 70 CBPR studies, that 56 intervention studies had different designs, and finally 8 studies met the inclusion criteria. The findings show that collaboration among community partners, researchers, and organizations led to community-level action to improve the health and wellbeing and to minimize health disparities. It enhanced the capacity of the community in terms of research and leadership skills. The result provided examples of effective CBPR that took place in a variety of communities. However, little has been written about the organizational capacities required to make these efforts successful. CONCLUSION: Some evidences were found for potentially effective strategies to increase the participant's levels of CBPR activities. Interventions that included community involvement have the potential to make important differences to levels of activities and should be promoted.
