RESUMEN
OBJECTIVE: Head/neck pain is one of the primary symptoms associated with spontaneous cervical artery dissection. Still, data on pain quality, intensity, and long-term dynamics are scarce. METHODS: Spontaneous cervical artery dissection subjects were included if mural hematoma was visualised through T1 fat-saturated MRI at baseline. All available medical records were evaluated and patients were invited to standardised clinical follow-up visits at least 1 year after the index event. RESULTS: In total, 279 subjects were included in the ReSect-study with head/neck pain being the most frequent symptom of spontaneous cervical artery dissection (220 of 273, 80.6%). Pain was of pulling nature in 107 of 218 (49.1%), and extended to the neck area in 145 of 218 (66.5%). In those with prior headache history, pain was novel in quality in 75.4% (42 of 55). Median patient-reported pain intensity was 5 out of 10 with thunderclap-type headache being uncommon (12 of 218, 5.5%). Prior to hospital admission, head/neck pain rarely responded to self-medication (32 of 218, 14.7%). Characteristics did not differ between subjects with and without cerebral ischemia. Pain resolved completely in all subjects within a median of 13.5 days (IQR 12). Upon follow-up in 42 of 164 (25.6%) novel recurring headache occurred, heterogeneous in quality, localisation and intensity. CONCLUSION: We present an in-depth analysis of spontaneous cervical artery dissection-related head/neck pain characteristics and its long-term dynamics.

INTRODUCTION: Identifying the cause of ischemic stroke in young adults is often difficult. Our objective was to compare the etiologic diagnostic strategy for ischemic stroke in young adults between 2 European centers and investigate the influence of workup variations in the diagnosed etiologies. PATIENTS AND METHODS: We included patients aged 18-55 years admitted for ischemic stroke or transient ischemic attack to the stroke units of Santa Maria Hospital in Lisbon, Portugal, and Innsbruck University Hospital in Innsbruck, Austria, between 2014 and 2016. Etiology and diagnostic procedures were compared between centers. RESULTS: We included 156 patients from Innsbruck University Hospital and 110 patients from Santa Maria Hospital. Search for intracranial large-vessel disease was performed mainly by computed tomography/magnetic resonance angiography in Innsbruck (83.9% versus 52.7%; P < .01) and by transcranial Doppler in Lisbon (91.8% versus 43.2%; P < .01). Transoesophageal echocardiography was preferred in Innsbruck for detecting paradoxical embolism (80.0% versus 68.2%; P < .05), whereas in Lisbon contrast transcranial Doppler was preferred (80.9% versus 3.9%; P < .01). For investigation of other causes, Lisbon patients were more commonly screened for thrombophilia (100.0% versus 92.3%; P < .05) and autoimmune disorders (91.7% versus 44.5%; P < .01) while in Innsbruck consultation by other specialists was more frequent (51.6% versus 10.0%; P < .01). No significant differences were found in etiologies between centers. CONCLUSION: The differences in diagnostic workup did not influence etiologic diagnosis. Extensive laboratory testing does not seem to influence diagnosis of stroke of other determined cause, emphasizing the importance of a clinically-oriented approach for the etiologic diagnosis of stroke in young adults.

Therapeutic effect of recombinant tissue-plasminogen activator (rt-PA) is time dependent. There is limited evidence whether localization of stroke within the posterior circulation (PCS) is associated with a treatment delay. We aimed to analyze within a nationwide multicenter cohort whether duration of pre- and intra-hospital patient management differs between patients with PCS and anterior circulation strokes (ACS). We studied onset-to-door-times (ODT) and door-to-needle-times (DNT) of all patients with acute ischemic stroke (IS) enrolled in the Austrian Stroke Unit Registry according to infarct localization. Classification into PCS and ACS was based on clinical presentation applying the criteria used in the Oxfordshire Community Stroke Project. Relationships between ODT, respectively, DNT and explanatory variables were modeled by multivariate linear regression. Between 2003 and 2015, 71010 patients with IS were enrolled, 11,924 with PCS and 59,086 with ACS. Overall, the ODT was significantly longer in PCS: median (IQR): 170 (25th, 75th: 79,420) min versus 110 (60,240); p < 0.001; this finding held true in multivariable analysis. In 10535 rt-PA-treated patients (1022 PCS/9832 ACS), ODT and DNT were significantly longer among those with PCS: ODT: median: 80 min (55,120) versus 72 (50,110), p < 0.001; DNT: 57 (35.90) versus 45 (30.67), p < 0.001. In the multivariate model, PCS was significantly associated with delay in the DNT. In conclusion, in this large nationwide cohort, patient management was significantly slower in PCS as compared to ACS. Increasing awareness about these delays and further elaboration of the underlying causes may translate into higher proportions of patients with PCS receiving rt-PA.

OBJECTIVE: It is not clear whether risk scores for early stroke recurrence after TIA that have been mainly established in outpatient and emergency department settings are valid on the background of highly specialized stroke unit care. METHODS: ABCD2 and ABCD3-I scores have been prospectively documented in a cohort of patients admitted to Austrian stroke units within 24 hours of symptom onset with TIA or minor stroke (NIH Stroke Scale score <4). RESULTS: A total of 5,237 TIA and minor stroke patients met inclusion criteria, with 3-month follow-up data available on 2,457. Early and 3-month stroke were observed in 2.4% and 4.2% of the study population. The probability of early stroke during the stroke unit stay (median 2 [interquartile range 1-3] days) steadily increased from 0% to 4.8% and 0% to 16.7% with increasing ABCD2 and ABCD3-I score points, respectively. On 3-month follow-up, stroke risk increased from 0% to 8.0% and 0% to 23.8% with increasing ABCD2 and ABCD3-I score points, respectively. Of the individual score components, age, blood pressure, and diabetes were not related to early or 3-month stroke, whereas clinical presentation (C), symptom duration (D), and cerebral as well as carotid imaging (I) were and accounted for the information provided by the full scores. CONCLUSIONS: Standard ABCD2 and ABCD3-I scores are useful instruments to estimate the probability of early and 3-month stroke in TIA and minor stroke patients treated at specialized stroke units, with C, D, and I being the most important score components in this setting.
