Background and aims: The main objective of this research was finding the relations between musculoskeletal disorders and depression and anxiety (overt and covert) in emergency staff of hospitals covered by Shahid Beheshti University of Medical Sciences. Methods: The research was descriptive- analytical study. Out of 600 staff of hospitals covered by Shahid Beheshti University of Medical Sciences, 120 were selected randomly as sample group in 2012. Socio-demographic, Nordic Musculoskeletal Disorders, CES-D and Schpillberger anxiety scales were applied as research tools. SPSS19 software and statistical techniques such as t-test, Pearson correlation coefficient, and one- way ANOVA were employed for analyzing the data. Results: Depression was lower and anxiety was upper than average amounts. There was significant relationship between depression and musculoskeletal disorders. Also, there was a significant difference in depression with respect to job title and educations. There were not observed such differences in overt and covert anxiety among staff. Staff with contract recruitment were suffering from depression more than other groups. It was found significant relationship between depression and anxiety, also overt and covert anxiety. Conclusion: The overt and covert anxiety of emergency staff is in the high level in order to the harmful nature of their jobs. Emergency managers and physicians have lower depression in comparison with other groups because of their low physical pressure. Further to the stressful nature of emergency job without concerning the job position, whole of the staff have high overt and covert anxiety.

Aim: To compare the frequency of the metabolic syndrome and its components in a sample of patients with rheumatoid arthritis (RA) and controls. Methods: This case control study was performed on 188 women over 18 years old: 92 RA patients and 96 healthy controls, from 2006 to 2008. Blood pressure, height, weight and waist circumference were measured. Blood was collected for the measurement of fasting glucose, lipid profile and insulin. The frequency of the metabolic syndrome was determined in case and control groups, using both WHO and National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) criteria. Results: According to the NCEP criteria, the frequency of metabolic syndrome in RA patients and controls were 27.2% and 35.4%, respectively (P = 0.22). Based on WHO criteria, 19.6% of RA patients and 21.9% of the control group were subject to metabolic syndrome (P = 0.70). The proportion with hypertension was greater in RA patients than the control group. The duration of RA was significantly higher in patients with metabolic syndrome compared to those without metabolic syndrome using both the WHO and NCEP criteria. Conclusions: There was no evidence of a greater prevalence of metabolic syndrome in RA patients compared with controls in this study. The duration of RA was associated with metabolic syndrome, implicating the role of inflammation in metabolic syndrome development.

Objectives This study aims to determine the effects of oral glucosamine on glucose metabolism and insulin resistance in non-diabetic patients with osteoarthritis in Northeastern Iran. Patients and methods This placebo-controlled, randomized clinical trial included 40 non-diabetic patients with osteoarthritis (15 males, 25 females, mean age 63.8±7.64 years; range 49 to 80 years). Patients were randomly divided into two equal groups and treated with oral glucosamine sulfate 1500 mg a day or placebo for 90 days. Fasting blood sugar, glucose tolerance test with 75 grams glucose and serum insulin levels, and homeostatic model assessment-insulin resistance were evaluated initially and at the end of intervention. Results There were no significant differences between the groups in terms of blood sugar, glucose tolerance test, and insulin levels at the beginning and end of the study. In the oral glucosamine group, there were no significant changes in fasting blood sugar (94.1±7.14 mg/dL versus 93.5±9.45 mg/dL, p=0.15), glucose tolerance test (99.3±8.99 mg/dL versus 103.3±10.1 mg/dL, p=0.07), and homeostatic model assessment-insulin resistance (1.57±0.21 versus 1.48±0.21, p=0.13) after treatment. Also, placebo did not significantly affect serum glucose levels and insulin resistance. Conclusion Oral glucosamine with routine dosage was safe in our non-diabetic patients with osteoarthritis and had no significant effect on glucose metabolism and insulin resistance.

Introduction Behçet's disease is an inflammatory disorder of unknown origin, with mucocutaneous, ocular, articular, vascular, gastrointestinal and central nervous system manifestations. Although cardiac involvement is not an uncommon manifestation of Behçet's disease, coronary aneurysm has rarely been reported. Case presentation A 36-year-old Iranian man was admitted to our emergency department for retrosternal pain of two and a half hours duration. His detailed medical history revealed that he had no risk factors for coronary artery disease, however, Behçet's disease had been diagnosed about 10 years earlier. His electrocardiogram showed inferior myocardial infarction. He underwent coronary angiography that showed multiple giant aneurysms in his coronary arteries. Two months later, he experienced another episode of unstable angina. This was followed by two episodes of anterior myocardial infarction 2 and 5 months afterwards. Conclusion This case highlights the importance of careful diagnostic work-up in the evaluation of myocardial infarction in patients. In our patient, Behçet's disease proved to be the cause of recurrent myocardial infarction.
