The SITS-UTMOST: A registry-based prospective study in Europe investigating the impact of regulatory approval of intravenous Actilyse in the extended time window (3-4.5 h) in acute ischaemic stroke.

INTRODUCTION: The SITS-UTMOST (Safe Implementation of Thrombolysis in Upper Time window Monitoring Study) was a registry-based prospective study of intravenous alteplase used in the extended time window (3-4.5 h) in acute ischaemic stroke to evaluate the impact of the approval of the extended time window on routine clinical practice. PATIENTS AND METHODS: Inclusion of at least 1000 patients treated within 3-4.5 h according to the licensed criteria and actively registered in the SITS-International Stroke Thrombolysis Registry was planned. Prospective data collection started 2 May 2012 and ended 2 November 2014. A historical cohort was identified for 2 years preceding May 2012. Clinical management and outcome were contrasted between patients treated within 3 h versus 3-4.5 h in the prospective cohort and between historical and prospective cohorts for the 3 h time window. Outcomes were functional independency (modified Rankin scale, mRS) 0-2, favourable outcome (mRS 0-1), and death at 3 months and symptomatic intracerebral haemorrhage (SICH) per SITS. RESULTS: 4157 patients from 81 centres in 12 EU countries were entered prospectively (N = 1118 in the 3-4.5 h, N = 3039 in the 0-3 h time window) and 3454 retrospective patients in the 0-3 h time window who met the marketing approval conditions. In the prospective cohort, median arrival to treatment time was longer in the 3-4.5 h than 3 h window (79 vs. 55 min). Within the 3 h time window, treatment delays were shorter for prospective than historical patients (55 vs. 63). There was no significant difference between the 3-4.5 h versus 3 h prospective cohort with regard to percentage of reported SICH (1.6 vs. 1.7), death (11.6 vs. 11.1), functional independency (66 vs. 65) at 3 months or favourable outcome (51 vs. 50). DISCUSSION: Main weakness is the observational design of the study. CONCLUSION: This study neither identified negative impact on treatment delay, nor on outcome, following extension of the approved time window to 4.5 h for use of alteplase in stroke.

Delay in seeking medical help following Transient Ischemic Attack (TIA) or "mini-stroke": a qualitative study.

BACKGROUND: Prompt treatment following Transient Ischemic Attack (TIA) can reduce the risk of subsequent stroke and disability. However, many patients delay in making contact with medical services. This study aimed to explore TIA patients' accounts of delay between symptom onset and contacting medical services including how decisions to contact services were made and the factors discussed in relation to delay. METHODS: Twenty interviews were conducted with TIA patients in England. Using a previous systematic review as an initial framework, interview data were organised into categories of symptom recognition, presence of others and type of care sought. A thematic analysis was then conducted to explore descriptions of care-seeking relevant to each category. RESULTS: Delay in contacting medical services varied from less than an hour to eight days. Awareness of typical stroke symptoms could lead to urgent action when more severe TIA symptoms were present but could lead to delay when experienced symptoms were less severe. The role of friends and family varied widely from deciding on and enacting care-seeking decisions to simply providing transport to the GP practice. When family or friends played a greater role, and both made and enacted care-seeking decisions, delays were often shorter, even when patients themselves failed to identify symptoms. Healthcare professionals also impacted on patients' care-seeking with greater delays in seeking further care for the same episode described when patients perceived a lack of urgency during initial healthcare interactions. CONCLUSIONS: This study provides new information on patients' decisions to contact medical services following TIA and identifies overlapping factors that can lead to delay in receiving appropriate treatment. While recognition of symptoms may contribute to delay in contacting medical services, additional factors, including full responsibility being taken by others and initial healthcare interactions, can over-ride or undermine the importance of patients' own identification of TIA.

Acute stroke secondary to carotid artery dissection in a patient with germ cell tumour: did cisplatin play a role?.

BACKGROUND: Cisplatin-based chemotherapy - mainly the bleomycin, etoposide and cisplatin (BEP) regimen - has significantly improved the prognosis of testicular germ cell tumours (GCT). However, it has serious vascular side effects, including acute ischemic stroke. CASE REPORT: A 37-year-old man with no conventional cerebrovascular risk factors presented with right arm clumsiness followed by a transient episode of expressive dysphasia 3 h later. He was receiving the third cycle of BEP for metastatic retroperitoneal GCT. Brain computed tomography (CT) and diffusion-weighted magnetic resonance imaging (MRI) confirmed multiple acute infarctions in the left middle cerebral artery territory. MR angiography and CT angiography showed a dissection with flaps extending into the left internal and external carotid arteries. The patient was anticoagulated and made an almost complete recovery. CONCLUSION: Carotid artery dissection has not been reported as the cause of cisplatin-associated stroke in patients with GCT. This case demonstrates the potential for cisplatin-induced mechanisms causing carotid dissection, particularly considering the close temporal association of BEP and the event in our patient. In young patients with excellent curative potential from GCT, every effort should be made to minimise the risk of disabling side effects of BEP. After a stroke, imaging of intracranial and extracranial arteries, monitoring and correction of serum magnesium is recommended. The decision to continue or discontinue cisplatin-based chemotherapy should be individualised.

Coexistent hereditary and inflammatory neuropathy.

Classically, the course of Charcot-Marie-Tooth (CMT) disease is gradually progressive. We describe eight atypical patients who developed acute or subacute deterioration. Seven of these had genetically proven CMT disease type 1A (CMT1A) due to chromosome 17p11.2-12 duplication, and one had X-linked disease (CMTX) due to a mutation in the GJB1 gene. In this group there was sufficient clinical, electrophysiological and neuropathological information to indicate a diagnosis of a superimposed inflammatory polyneuropathy. The age range of the patients was 18-69 years, with a mean of 39 years. A family history of a similar neuropathic condition was present in only four patients. All eight had an acute or subacute deterioration following a long asymptomatic or stable period. Seven had neuropathic pain or prominent positive sensory symptoms. Nerve biopsy demonstrated excess lymphocytic infiltration in all eight patients. Five patients were treated with steroids and/or intravenous immunoglobulin, with variable positive response; three patients received no immunomodulatory treatment. Inflammatory neuropathy has previously been recognized in patients with hereditary neuropathy, with uncharacterized genetic defects and with CMT1B. We present detailed assessments of patients with CMT1A and CMTX, including nerve biopsy, and conclude that coexistent inflammatory neuropathy is not genotype-specific in hereditary motor and sensory neuropathy. Although this was not a formal epidemiological study, estimates of the prevalence of CMT disease and chronic inflammatory demyelinating polyneuropathy indicate that the association is more frequent than would be expected by chance. This has implications for understanding the pathogenesis of inflammatory neuropathies and raises important considerations in the management of patients with hereditary neuropathies. If a patient with CMT disease experiences an acute or subacute deterioration in clinical condition, treatment of a coexistent inflammatory neuropathy with steroids or immunoglobulin should be considered.
