Early and intermediate prognosis of intravenous thrombolytic therapy in acute ischemic stroke subtypes according to the causative classification of stroke system.

OBJECTIVES: Intravenous thrombolytic therapy has established acceptable results in treating ischemic stroke. However, there is little information on treatment outcome especially in different subtypes. The aim of current study was to evaluate early and intermediate prognosis in intravenous thrombolytic therapy for acute ischemic stroke subtypes. METHODOLOGY: Forty eligible patients (57.5% male with mean age of 63.18±13.49 years) with definite ischemic stroke who were admitted to emergency department of Imam Reza University Hospital, in the first 180 minutes after occurrence received recombinant tissue plasminogen activator. All investigation findings were recorded and stroke subtypes were determined according to the Causative Classification of Stroke System. Stroke severity forms including modified Rankin Scale (mRS) and National Institutes of Health Stroke Scale (NIHSS) scores were recorded for all patients in first, seven and 90 days after stroke and disease outcome was evaluated. RESULTS: The etiology of stroke was large artery atherosclerosis in 20%, cardio-aortic embolism in 45%, small artery occlusion in 17.5% and undetermined causes in 17.5%. NIHSS and mRS scores were significantly improved during time (P < 0.001 in both cases). Three months mortality rate was 25%. Among the etiologies, patients with small artery occlusion and then cardio-aortic embolism had lower NIHSS score at arrival (P = 0.04). Caplan-meier analysis showed that age, sex and symptom to needle time could predict disease outcome. CONCLUSION: Intravenous thrombolytic therapy is accompanied by good early and intermediate outcome in most patients with ischemic stroke. Small artery occlusion subtype had less disease severity and higher improvement.

Somatoform Dissociation, Fatigue Severity and Pain Behavior Compared in Patients with Migraine Headache and in Healthy Individuals.

The prevalence of migraine in the world is about 15 and 7% among women and men, respectively. The purpose of this study was comparison of somatoform dissociation, fatigue severity and pain behavior in patients with migraine headache and its relationship with coping strategies. This descriptive analytical study has been done on 120 patients with migraine headache and 120 healthy subjects were selected randomly. Data collected by somatoform dissociation questionnaire (SDQ-20), fatigue severity scale, pain behavior scale and coping strategies scale. For data analysis we used SPSS.19. The means of the somatoform dissociation, pain behavior scale, help searching subscale and pain compliant in migraine and healthy subjects were statistically significant. There was not significant difference in avoidance subscales between the two groups. Comparison of fatigue severity in patients with migraine and control group was meaningful. There was significant positive correlation between all four scales and coping strategies. It seems that these symptoms can play an important role in this disease; thus, their careful evaluation in the treatment of migraine headache is essential.
