Objective: The aim of the present study was to assess emergency neurology management in Italy by comparing patients admitted to the hub and spoke hospitals., Methods: Data obtained from the annual Italian national survey (NEUDay) investigating the activity and facilities of neurology in the emergency room conducted in November 2021 were considered. Information for each patient who received a neurologic consultation after accessing the emergency room was acquired. Data on facilities were also gathered, including hospital classification (hub vs spoke), number of consultations, presence of neurology and stroke unit, number of beds, availability of neurologist, radiologist, neuroradiologist, and instrumental diagnostic accessibility., Results: Overall, 1,111 patients were admitted to the emergency room and had neurological consultation across 153 facilities (out of the 260 Italian ones). Hub hospitals had significantly more beds, availability of neurological staff, and instrumental diagnostic accessibility. Patients admitted to hub hospital had a greater need for assistance (higher number of yellow/red codes at neurologist triage). A higher propensity to be admitted to hub centers for cerebrovascular problems and to receive a diagnosis of stroke was observed., Conclusions: The identification of hub and spoke hospitals is strongly characterized by the presence of beds and instrumentation mainly dedicated to acute cerebrovascular pathologies. Moreover, the similarity in the number and type of accesses between hub and spoke hospitals suggests the need to look for adequate identification of all the neurological pathologies requiring urgent treatment., (© 2023.

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., (© 2023.

Objective: To estimate the incidence and describe clinical characteristics and outcome of GBS in COVID-19 patients (COVID19-GBS) in one of the most hit regions during the first pandemic wave, Lombardia., Methods: Adult patients admitted to 20 Neurological Units between 1/3-30/4/2020 with COVID19-GBS were included as part of a multi-center study organized by the Italian society of Hospital Neuroscience (SNO)., Results: Thirty-eight COVID19-GBS patients had a mean age of 60.7 years and male frequency of 86.8%. CSF albuminocytological dissociation was detected in 71.4%, and PCR for SARS-CoV-2 was negative in 19 tested patients. Based on neurophysiology, 81.8% of patients had a diagnosis of AIDP, 12.1% of AMSAN, and 6.1% of AMAN. The course was favorable in 76.3% of patients, stable in 10.5%, while 13.2% worsened, of which 3 died. The estimated occurrence rate in Lombardia ranges from 0.5 to 0.05 GBS cases per 1000 COVID-19 infections depending on whether you consider positive cases or estimated seropositive cases. When we compared GBS cases with the pre-pandemic period, we found a reduction of cases from 165 to 135 cases in the 2-month study period in Lombardia., Conclusions: We detected an increased incidence of GBS in COVID-19 patients which can reflect a higher risk of GBS in COVID-19 patients and a reduction of GBS events during the pandemic period possibly due to a lower spread of more common respiratory infectious diseases determined by an increased use of preventive measures., (© 2022.

Background: The assessment of human and diagnostic resources is a prerequisite to improving the management of emergency neurology., Objective: To provide a landscape on the organization of the Lombardy Region hospitals for emergency neurological care management., Methods: We designed an anonymized questionnaire including 6 sections with 21 questions on facilities, human and diagnostic resources, and intra- and between-hospital connections. The time needed to fill the questionnaire was estimated not to exceed 6 min., Results: The questionnaire was returned by 33/41 (80.5%) hospitals, 22 classified as level 1 (spoke), and 11 as level 2 (hub). Five of 33 (15%) did not have a neurology unit. The mean annual rate of neurological consultations accounted for 5-6% of all admissions (range 2-8%) and did not differ between levels 1 and 2 hospitals. Neurologists were 24-h available in 21/33 (64%) hospitals, 12-h and on call at night in 6 (18%), less than 12 h without nocturnal availability in 5 (15%), and neither present nor available in 1 (3%). Brain CT and CSF examinations were 24-h universally available, whereas EEG and neurosonology were not in most hospitals. Despite angio-CT was 24-h available in more than 75% of the hospitals, only 45% of them had 24-h availability of diffusion/perfusion imaging, and 43% were not available at any time. Only 12% of the hospitals had 24-h availability of neuroradiologists and 6% of interventional neuroradiologists., Conclusion: Our data, while emphasizing current critical issues, offer clues for identifying priorities and improving the management of emergency and time-dependent neurological diseases., (© 2022.

Long-term consequences of cervical artery dissection (CeAD), a major cause of ischemic stroke in young people, have been poorly investigated. The Italian Project on Stroke at Young Age - Cervical Artery Dissection (IPSYS CeAD) project is a multicenter, hospital-based, consecutively recruiting, observational, cohort study aimed to address clinically important questions about long-term outcome of CeAD patients, which are not covered by other large-scale registries. Patients with radiologically diagnosed CeAD were consecutively included in the registry. Baseline demographic and clinical variables, as well as information on risk factors, were systematically collected for each eligible patient. Follow-up evaluations were conducted between 3 and 6 months after the initial event (t 1 ) and then annually (t 2 at 1 year, t 3 at 2 years , and so on), in order to assess outcome events (long-term recurrent CeAD, any fatal/nonfatal ischemic stroke, transient ischemic attack (TIA), or other arterial thrombotic event, and death from any cause). Between 2000 and 2019, data from 1530 patients (age at diagnosis, 47.2 ± 11.5 years; women, 660 [43.1%]) have been collected at 39 Italian neurological centers. Dissection involved a single vessel in 1308 (85.5%) cases and caused brain ischemia in 1303 (85.1%) (190 TIA/1113 ischemic stroke). Longitudinal data are available for 1414 (92.4%) patients (median follow-up time in patients who did not experience recurrent events, 36.0 months [25th to 75th percentile, 63.0]). The collaborative IPSYS CeAD effort will provide novel information on the long-term outcome of CeAD patients. This could allow for tailored treatment approaches based on patients' individual characteristics.

There are currently no data available on the prevalence of symptomatic intracranial atherosclerosis (ICAS) in Italy. The aim of this prospective, multicenter, hospital-based, transcranial ultrasound study was to establish the prevalence of ICAS among patients hospitalized with acute ischemic stroke. At 11 stroke centers across Italy, patients consecutively admitted for their first ever acute ischemic stroke were assessed prospectively over a 24-month period either with transcranial color-coded Doppler sonography (TCCS) or transcranial Doppler (TCD) according to validated criteria. ICAS was diagnosed when there was an evidence of a cerebral infarction in the territory of a ≥50 % stenosis detected by TCCS/TCD and confirmed by magnetic resonance angiography or computed tomography angiography. A total of 1134 patients were enrolled, 665 of them (58.6 %) men, with a mean age of 71.2 ± 13.3 years. ICAS was recorded in 99 patients (8.7 % of the whole sample, 8.9 % among Caucasians), most commonly located in the anterior circulation (63 of 99, 5.5 %). After adjusting for potential confounders, multivariate analysis identified carotid/vertebral ≥50 % stenosis [odds ratio (OR) 2.59, 95 % (confidence interval) CI 1.77-6.33; P = 0.02] and hypercholesterolemia (OR 1.38, 95 % CI 1.02-1.89; P = 0.02) as being independently associated with ICAS. ICAS is a surprisingly relevant cause of ischemic stroke in Italy, identified in almost 9 % of first-ever stroke patients. It is more prevalent in the anterior circulation and independently associated with hemodynamically significant cervical vessel atherosclerosis and hypercholesterolemia. These findings support the systematic use of transcranial ultrasound to identify ICAS in patients presenting with acute ischemic stroke and in cases with ≥50 % cervical vessel stenoses.

Platypnea-orthodeoxia is a syndrome characterized by dyspnea and hypoxemia in orthostatism relieved by supine position. This phenomenon is frequently associated with interatrial communication, mainly patent foramen ovale. The association of platypnea-orthodeoxia syndrome with recurrent stroke and patent foramen ovale is extremely uncommon. A 73-year-old woman experienced recurrent attacks of dyspnea after an ischemic stroke. Arterial blood gas analysis changes in upright and supine position confirmed the diagnosis of platypnea-orthodeoxia syndrome. Contrast-enhanced transthoracic echocardiography showed patent foramen ovale with atrial septal aneurysm and right-to-left shunt. Percutaneous closure of patent foramen ovale led to stabilization of blood oxygen saturation and resolution of dyspnea. Platypnea-orthodeoxia syndrome should be considered in patients with stroke and unexplained dyspnea. The diagnosis could lead to correction of an unknown cardiac defect and of potential risk factor for stroke.
