Factors associated with early improvement after intravenous thrombolytic treatment in acute ischemic stroke.

OBJECTIVE: : The aim of this study was to determine the factors associated with early neurological improvement (ENI) in patients who experienced acute ischemic stroke and were treated with intravenous recombinant tissue plasminogen activator (IV rt-PA), and determine the relationship with the outcome at the first control. METHOD: : This study included 377 patients who were treated with IV rt-PA in Izmir Dokuz Eylül University Hospital between January 2010 and October 2018. ENI was defined as a 4 or more improvement in the National Institutes of Health Stroke Scale (NIHSS) score in the first hour, the twenty-fourth hour and the seventh day when compared to the pretreatment phase. The modified Rankin Scale (mRS) 0-1 score was defined as 'very good outcome'. RESULTS: : The basal NIHSS (p=0.003, p=0.003, p=0.022) was high in the first hour, twenty-fourth hour, and seventh day ENI groups. Blood urea nitrogen (BUN) level was low in the first- and twenty-fourth-hour ENI groups (p=0.007, p=0.020). Furthermore, admission glucose was low at the twenty-fourth hour and on the seventh day ENI groups (p=0.005, p=0.048). A high infarct volume was observed on magnetic resonance imaging (MRI) at the twenty-fourth hour and on the seventh day non-ENI groups (p= <0.001, p= <0.001). CONCLUSION: : Management of factors associated with ENI and determination of treatment strategies accordingly are important for obtaining a better clinical outcome. It can help quickly select patients, who, even though they will not respond to rt-PA, may be appropriate candidates for bridging therapy.

Cluster headache: a single tertiary center study.

OBJECT: The characteristics of cluster headache (CH) patients in many countries and the diagnostic and therapeutic approach have been described in several publications, but so far no clinical data have been published from Turkey. MATERIAL METHODS: This is a cross-sectional retrospective study that includes all patients who were diagnosed with CH and referred to our headache clinic, Dokuz Eylül University Faculty of Medicine, Neurology Department from 1991 to January 2018. RESULTS: We included 114 patients (24 females and 90 males) in our study. The mean age at onset was 31.68 ± 12.72 (range 13-68). Eighty-six (78.18%) patients had episodic cluster headache (ECH) and 24 (21.82%) patients had chronic cluster headache (CCH). The age at onset was significantly higher in the patients with CCH than with ECH (p = 0.002). The most common location was orbitotemporal for both genders. The most common accompanying symptoms were lacrimation (80.73%). The male:female ratio in all patients was 3:7, 3.8:1 in those with CCH and 4:1 in those with ECH. Eighty-nine (87.25%) patients had prophylactic treatment and 60 of them received verapamil. CONCLUSION: In our study, some clinical features of our patients were similar to those of Europe and America or the Asian countries and some of them not. There are regional differences in cluster headache patients. With more awareness of cluster headache and research from many countries, clinical differences can be revealed more objectively in the future.
