Purpose: To assess the effect of oral omega-3 fatty acids on tear break-up time (TBUT), Schirmer's score, and Ocular Surface Disease Index (OSDI) through a double-blind clinical trial. Design: Randomized, double-blind clinical trial. Participants: Sixty-four patients with dry eye symptoms between the ages of 45 and 90 years were randomized into 2 groups: 33 persons in the treatment group and 31 persons in the placebo group. Methods: The treatment group received 2 capsules of omega-3 (each containing 180 mg eicosapentaenoic acid [EPA] and 120 mg docosahexaenoic acid [DHA]) daily for 30 days, and the placebo group received 2 medium-chain triglyceride oil capsules daily for 1 month. The outcomes were measured 1 month after the intervention. Main Outcome Measures: The primary outcome measure was an increase from baseline in TBUT at day 30. Secondary outcome measures were a decrease from baseline in the OSDI score and an increase in the Schirmer's score at day 30. Results: In the placebo group, before the intervention, the mean TBUT, OSDI, and Schirmer's scores were 4.5 ± 2.1 seconds, 36.4 ± 13.8, and 6.0 ± 2.6 mm, respectively, and 1 month later were 4.7 ± 2.6 seconds, 37.6 ± 13.5, and 6.2 ± 2.5 mm, respectively. In the treatment group, these values were 3.9 ± 1.7 seconds, 38.7 ± 16.5, and 5.8 ± 2.5 mm before the intervention and 5.67 ± 2.6 seconds, 29.3 ± 15.9, and 6.8 ± 2.8 mm after the intervention, respectively. Repeated-measures analysis of variance showed that improvements in TBUT, OSDI, and Schirmer's scores were significantly better in the treatment group than in the placebo group. The changes in the treatment and placebo groups were 71% and 3.3% for TBUT (P < 0.001), 26% and 4% (P=0.004) for dry eye symptoms, and 22.3% and 5.1% for Schirmer's score (P=0.033), respectively. Conclusions: This study demonstrated that oral consumption of omega-3 fatty acids (180 mg EPA and 120 mg DHA twice daily for 30 days) is associated with a decrease in the rate of tear evaporation, an improvement in dry eye symptoms, and an increase in tear secretion.

To assess the one year results of Artiflex Phakic intraocular lens (IOL) implantation in the treatment of high myopia. In this non-random interventional study, myopic patients with spherical equivalent worse than -5.0 diopters (D) who were not eligible for laser surgery were assessed. All patients had refraction, uncorrected and best corrected visual acuity tests (UCVA and BCVA), endothelial cell count (ECC), and measurement of the anterior chamber depth and intraocular pressure before surgery and at 1, 3, 6, and 12 months after surgery. Main outcome measures of this study were refractive stability, refractive predictability, safety, and efficacy after implanting Artiflex IOLs. We studied 53 eyes of 20 female and 8 male patients. The mean preoperative spherical equivalent was -10.22±3.02 D which reached -0.69±1.08 D one year after surgery (P<0.001). On the last follow-up visit, 75% of the eyes were within +0.5 D of emmetropia, 2 eyes had lost one line of BCVA, 18.75% had gained one line and 31.25% had gained 2 or more lines of BCVA. Others showed no change in BCVA. At one year after surgery, 72.2% of the eyes had 20/25 vision or better. The safety and efficacy indices were 1.16 and 1.05, respectively. ECC showed 3.04% decrease (P=0.176). In cases where laser surgery is not an option for myopic patients, use of Artiflex IOLs can have good results with acceptable safety and efficacy. © 2013 Tehran University of Medical Sciences.

Educating emergency medical staffs in triage skills is an important aspect of disaster preparedness. The aim of the study was to compare the effect of role-playing and educational video presentation on the learning and performance of the emergency medical service staffs in Khozestan, Iran A total of 144 emergency technicians were randomly classified into two groups. A researcher trained the first group using an educational video method and the second group with a role-playing method. Data were collected before, immediately, and 15 days after training using a questionnaire covering the three domains of demographic information, triage knowledge, and triage performance. The data were analyzed using defined knowledge and performance parameters. There was no significant difference between the two training methods on performance and immediate knowledge (P = .2), lasting knowledge (P=.05) and immediate performance (P = .35), but there was a statistical advantage for the role-playing method on lasting performance (P = .02). The two educational methods equally increase knowledge and performance, but the role-playing method may have a more desirable and lasting effect on performance. Source

Background: The present study was conducted to investigate the possible outcome of interaction between endothelial nitric oxide (NOS3) G894T and cholesteryl ester transfer TaqIB variants on the risk of coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM). The sample included a total of 207 CAD patients (102 CAD patients with T2DM and 105 CAD patients without T2DM). There were also 101 patients with T2DM and 92 age- and sex-matched healthy individuals as controls. All study participants were from Western Iran. The sample was genotyped by polymerase chain reaction-restriction fragment length polymorphism. Results: The presence of NOS3 T allele was not associated with the risk of CAD or T2DM, and the CETP B1 allele was only significantly associated with the increased risk of CAD in total CAD patients (odds ratio (OR) = 5.1, p = 0.019). However, the concomitant presence of both CETP B1 and NOS3 T alleles significantly increased the risk of CAD in total CAD patients (OR = 18.1, p < 0.001), in CAD patients without T2DM (OR = 27.1, p = 0.03), and in CAD patients with T2DM (OR = 13.5, p = 0.002). Also, the presence of both alleles increased the risk of T2DM (OR = 12, p = 0.004). Conclusions: Our findings, for the first time, indicate that NOS3 T allele strongly interacts with CETP B1 allele to augment the risk of CAD and T2DM in the population of Western Iran. © 2012 Rahimi et al.

Scorpion stings are a public health problem in south and southwest Iran. There is little information regarding climatological effects on incidence of scorpion stings in Iran. Therefore, the present systemic survey of scorpion sting data was conducted from the point of view of entomo-meteorological relationships and analyzed statistically for the Dezful area in Khuzestan, southwest of Iran. The time series analysis was implemented using MINITAB version 16 statistical software packages. In total, 3,755 scorpion sting files from the Dezful health centers were monitored from April 2007 to September 2011 in a time series analysis. The results showed that temperature had significant effects on scorpion sting. From the data of this study, it is concluded that the scorpion activity in Dezful County is a climatological-dependent phenomenon. © The Author 2014.
