1.  Comparative interrater reliability of Asian Stroke Disability Scale, modified Rankin Scale and Barthel Index in patients with brain infarction 
ARYA Atherosclerosis  2012;8(3):153-157 .
BACKGROUND
This study tried to develop an Asian Stroke Disability Scale (ASDS) and compared its interrater reliability with modified Rankin Scale (mRS) and Barthel Index (BI).
METHODS
Three items including self-care, mobility, and daily activities were selected as variables for development of the ASDS. The variables were provisionally graded on a 2- to 4-point scale based on the importance of each item. Each of the variables was categorized into 3 categories. Afterward, 125 rater-patient assessments for each scale (mRS, BI, and ASDS) were performed on 25 stroke patients by 5 raters. For categorization of functional impairment as minor or major, the scores of mRS, BI and ASDS were categorized as ≤ 2 and > 2, < 90 and ≥ 90, and < 3 and ≥ 3, respectively.125 rater-patient assessments for each of the mRS, BI, and ASDS were performed on 25 stroke patients by five raters.
RESULTS
The quantitative variability of BI, mRS, and ASDS scores was not significant (P = 0.379; P = 0.780; and P = 0.835, respectively). Interrater variability of mRS, BI, and ASDS scores based on qualitative categorization was not significant (P = 1.000; P = 0.978; and P = 0.901, respectively). Paired interrater variability of mRS, BI, and ASDS scores based on qualitative categorization was not significant (P > 0.05).
CONCLUSION
The ASDS is easy to use, requires less than 1 minute to complete and is as valid as mRS and BI in assessment of functional impairment of patients with stroke.

2.  Results of Surgical and Non-Surgical Treatment of Aneurysms in Iran 
ARYA Atherosclerosis  2011;6(4):136-139.
BACKGROUND
Direct surgery or endovascular procedures are an accepted way of treating patients with Aneurismal Subarachnoid Haemorrhage (SAH). However the impact of invasive methods of treatment on results in developing countries may differ from that in developed countries.
METHODS
This is a prospective clinical study of consecutive patients with Subarachnoid Haemorrhage (SAH) admitted in Ghaem hospital in Mashhad during 2005-2010. The initial diagnosis and investigations were carried out by neurologists. The patients were divided into two groups. One received surgical treatment whilst the other group was managed medically. The decision as to the choice of method of treatment was made by the neurosurgeons. The initial medical treatment was standardised for all the patients. The rate of complications and mortality was compared in both medical and surgical groups.
RESULTS
20 SAH patients (52% females) with a mean age of 50.6±7 years were evaluated. The angiography revealed the presence of an aneurysm in 62 patients. 63.5% of patients received medical treatment and 37.5% underwent aneurysmal surgery. Difference of rebleeding rate in two therapeutic groups was not significant; χ2=0.014, P=0.91. The effect of rebleeding on mortality was not significant; χ2=2.54, P=0.14. Within 62 SAH patients with cerebral aneurysm, the mortality rate in both therapeutic groups was also not significantly different; χ2=0.16, P=0.77.
CONCLUSION
There is no significant difference in the mortality rate between the “surgical” and non “surgical” groups of patients with SAH. This could be due to delay in performance of surgery in neurovascular centers in Iran.
