Models of care in emergency neurology: from the Neuro Fast Track to the emergency neurologist-a position paper of the Italian Association for Emergency Neurology (ANEU).

I n the context of an adequate health care organization, the figure of the neurologist as an emergency operator (in the emergency room-ER-and/or in a dedicated outpatient clinic) is crucial for an effective functional connection with the territory (and therefore with general practitioners), a reduction in inappropriate ER accesses, specific diagnostic and therapeutic approaches to neurological emergencies in the ER and a reduction in nonspecific or even unnecessary instrumental investigations. In this position paper of the Italian Association of Emergency Neurology (ANEU: Associazione Neurologia dell'Emergenza Urgenza), these issues are addressed, and two important organizational solutions are proposed: 1) The Neuro Fast Track, as an outpatient organization approach strongly linked to general practitioners and non-neurological specialists and dedicated to cases with deferrable urgency (to be assessed within 72 h) 2) The identification of an emergency neurologist, who is engaged in ER assessments as a consultant and involved in the management of the semi-intensive care unit of the emergency neurology and the stroke unit according to an appropriate rotation, as well as in consultations for patients with neurological emergencies in inpatient wards The possibility of computerizing the screening of patients with deferrable urgency in the Neuro Fast Track is described. A dedicated app represents an important tool that can facilitate the identification of patients for whom deferred assessment is appropriate, the scheduling of neurological examinations and reductions in the booking time through a more rapid approach to specialist assessment and subsequent investigations.

A checklist-based survey for early mobilization of stroke unit patients in an Italian region.

BACKGROUND: Although early mobilization (EM) is recommended by most guidelines in acute stroke patients, there is a paucity of tools to perform a standardized patient risk assessment prior to EM in stroke units (SUs). OBJECTIVE: This survey aimed at assessing (1) the usefulness of an ad hoc checklist for a standardized approach to EM in SUs and (2) the relationship between EM achieved by this checklist and SU characteristics. METHODS: This survey was carried out in 10 SUs in Piedmont, Italy. The EM checklist was based on 15 "items", including quantitative/qualitative, clinical and management features. RESULTS: A total of 250 completed checklists were assessed. EM, defined as out-of-bed activity within 72 h of admission, was reached by 174 patients (69.6%), according to the checklist. There was a statistically significant association between the admission NIHSS score and EM. Hypotension at mobilization was observed in 29/250 patients (11.6%) and was significantly associated with EM. A total of 6 falls (2.4%) were reported. Nurses were most frequently involved in EM, either alone (40.8%) or with another professional. CONCLUSION: A large percentage of acute stroke patients managed to achieve a safe EM in the SUs that adopted the novel checklist. These results suggest that this checklist may well be a user-friendly, reliable tool to assist SU professionals in deciding whether to mobilize or not, by means of a standardized approach.

Unilateral Poststroke Periodic Limb Movements: A Case Series.

Periodic limb movements (PLM) and restless leg syndrome (RLS) are involuntary common sleep-related movements which often hamper sleep onset; they are mostly idiopathic and bilateral but are seldom described secondary after a stroke. These cases are rare, often unilateral, and because of the usually transitory duration of symptoms, often under-recognized. When a treatment is required, it can be tricky and the drug choice not foregone. We report 2 patients with unilateral poststroke PLM with similar clinical pictures but different symptoms, therapy, and outcome. The first is a long-lasting unilateral PLM video case with chronic vascular lesions leading to insomnia even if with no urgence or any subjective symptoms as in RLS but well responding only to a definite RLS treatment. The second case is an acute, short-duration self-limiting PLM with positive brain MRI lesion imaging. Our cases suggest that unilateral poststroke PLM even if distinct in subjective and radiological features from secondary RLS can sometimes have a definite and effective dopaminergic treatment if long-lasting. Putative mechanism of chronic case 1 PLM could be due to a further stroke sparing sensory pathways and making the patient unaware of subjective RLS-like symptoms.

A retrospective study on early carotid endarterectomy within 48 hours after transient ischemic attack and stroke in evolution.

BACKGROUND: Large randomized controlled trials have shown that carotid endarterectomy (CEA) is beneficial in the treatment of recent severe symptomatic carotid stenosis. Data are lacking concerning the risks of early CEA (<48 hours) for stroke in evolution (SIE) or crescendo transient ischemic attack (CTIA). The primary end point of this retrospective study was to evaluate the incidence of stroke, major adverse cardiac events (MACEs), and death within the first 30 days after early CEA performed within 48 hours in patients presenting with transient ischemic attack (TIA)/SIE. METHODS: Between 2001 and 2010, we treated 3,023 carotid artery stenoses, 29.5% (891/3,021) of which were in symptomatic patients. Early CEA within 48 hours after acute TIA/SIE was performed in 176 patients. Patients were divided into 3 groups for analysis of outcome after early CEA in symptomatic patients according to their initial neurologic deficit. Group 1 included 55 patients with TIA (single); group 2 included 55 patients with CTIA, and group 3 included 66 patients with SIE. Carotid artery stenosis was evaluated by duplex ultrasonography (DS). All patients were pre- and postoperatively visited by an experienced consultant neurologist who evaluated the neurologic status according to the modified Rankin Scale and the National Institutes of Health Stroke Scale (NIHSS). At admission, surgery was not performed on patients with disabling neurologic deficit (NIHSS score: >6) except for 4 selected cases (NIHSS score range: 8-14), patients with cerebral lesions >3 cm in diameter, patients with the presence or suspicion of parenchymal hemorrhage, patients with occlusion of the middle cerebral artery, and those who were deemed unfit for surgery. Clinical and DS follow-up examinations were performed after 6 and 12 months and annually thereafter. The mean duration of follow-up was 29.4 months (range: 0-120 months). RESULTS: The cumulative TIA/stroke/myocardial infarction/death rate at 30 days was 3.9% (7/176). TIA and stroke rates were 0% (0/176) and 3.4% (6/176), respectively. The stroke rate in groups 1, 2, and 3 was 1.8% (1/55), 0% (0/55), and 7.6% (5/66), respectively. No hemorrhagic strokes, TIAs, or MACEs were detected after surgery. Stroke risk was higher in group 3 than in groups 1 or 2, but the differences in the 3 groups were not statistically significant (group 1 vs. group 2: 1/55 vs. 0/55 events [P = 0.3151]); group 1 vs. group 3: 1/55 vs. 5/66 events [P = 0.3020]; and group 2 vs. group 3: 0/55 vs. 5/66 events [P = 0.1039]. Thirty-day follow-up was available for all patients, while long-term follow-up (mean: 32.7 ± 26.8 months) was available only for 158 patients (1 patient died and 17 were lost to follow-up). CONCLUSIONS: CEA can be performed with an acceptable risk in properly selected symptomatic patients within 48 hours after TIA or SIE. The benefits of early CEA in symptomatic patients include the prevention of recurrent stroke.

Free-floating thrombus in the internal carotid artery: diagnosis and treatment of 16 cases in a single center.

BACKGROUND: Free-floating thrombus in the internal carotid artery (FFT-ICA) is a rare condition and its real incidence is unknown. The most common etiology is a complication of an atherosclerotic plaque, but several medical conditions can be responsible. The purpose of this study was to retrospectively analyze our experience with carotid endarterectomy in the management of FFT-ICA and also to analyze the patient outcome. METHODS: A retrospective review was performed of all patients admitted during the past 9 years with a diagnosis of FFT-ICA. Patient demographics, clinical manifestations, diagnostic modalities, surgical indications, operative details, postoperative courses, and follow-up information were recorded from the hospital database. RESULTS: Between January 2000 and December 2008, in our Unit, 2,572 carotid endarterectomies were performed for carotid artery disease. A total of 16 patients (16 of 2,572; 0.62%) were treated for an FFT-ICA. In all, 87.5% (14 of 16) of patients had neurological symptoms. All patients underwent a duplex scan. In 75% (12 of 16) of cases, additional diagnostic tests were performed: digital subtraction angiography (DSA), magnetic resonance angiography, or computed tomographic scan. Duplex scan and DSA detected the FFT-ICA in 62.5% and 100% of cases, respectively. Computed tomographic scan and magnetic resonance angiography failed to provide a diagnosis in majority of the patients (33.4% and 66.7%, respectively). The presence of FFT-ICA was confirmed intraoperatively in all cases. The cumulative stroke rate after surgery was 6.3% (one of 16). Of the total number of patients discharged, 68.75% showed an improvement of neurological symptoms, 12.5% were asymptomatic, 12.5% had no changes in symptoms, and 6.25% of cases worsened. At 30-day follow-up, the survival rate was 93.7% and 75% of patients showed an improvement of neurological symptoms, 12.5% were asymptomatic, and 6.25% died. In all, 6.25% of patients were lost to follow-up. CONCLUSION: Patients with FFT-ICA are usually symptomatic and present with an acute emergency. DSA remains the gold standard diagnostic test in FFT-ICA detection. We cannot assert that early surgery is superior to temporary anticoagulation and/or delayed intervention because of the absence of a comparison group. However, our retrospective results suggest that prompt intervention seems to be a safe alternative in FFT-ICA treatment.
