Telemedical stroke care significantly improves patient outcome in rural areas: Long-term analysis of the German NEVAS network.

Background: Comprehensive stroke centers (CSC) offer state-of-the-art stroke care in metropolitan centers. However, in rural areas, sufficient stroke expertise is much scarcer. Recently, telemedical stroke networks have offered instant consultation by stroke experts, enabling immediate administration of intravenous thrombolysis (IVT) on-site and decision on thrombectomy.

Neurologic manifestations of COVID-19 in critically ill patients: results of the prospective multicenter registry PANDEMIC.

Background: Neurologic manifestations are increasingly reported in patients with coronavirus disease 2019 (COVID-19). Yet, data on prevalence, predictors and relevance for outcome of neurological manifestations in patients requiring intensive care are scarce. We aimed to characterize prevalence, risk factors and impact on outcome of neurologic manifestations in critically ill COVID-19 patients.

Inter-hospital transfer for mechanical thrombectomy within the supraregional stroke network NEVAS.

Background: Telemedicine stroke networks are mandatory to provide inter-hospital transfer for mechanical thrombectomy (MT). However, studies on patient selection in daily practice are sparse.

Methods: Here, we analyzed consecutive patients from 01/2014 to 12/2018 within the supraregional stroke network "Neurovascular Network of Southwest Bavaria" (NEVAS) in terms of diagnoses after consultation, inter-hospital transfer and predictors for performing MT.

Brainstem encephalitis in neuroborreliosis: typical clinical course and distinct MRI findings.

Objective: In this retrospective observational study and referring to a historical case presented in 2009, we searched for typical clinical and imaging features of brainstem encephalitis in neuroborreliosis.

Methods: In addition to the historical case we describe five affected patients.

Results: All patients had a very similar prolonged clinical course with unspecific symptoms such as wasting, fatigue and headache.

Telling friend from foe in emergency vertigo and dizziness: does season and daytime of presentation help in the differential diagnosis?

Drip and ship for mechanical thrombectomy within the Neurovascular Network of Southwest Bavaria.

Objective: To determine feasibility and safety of stroke care organization within our Neurovascular Network of Southwest Bavaria (NEVAS) in a rural area with distances of up to 100 kilometers, we compared patients who underwent mechanical thrombectomy (MT) in large vessel occlusion admitted directly to our center (direct to center [DTC]) to patients who were transferred for MT via NEVAS (drip and ship [DS]).

Methods: This is a retrospective analysis of prospectively collected data of all MT patients between January 2015 and May 2018. Successful recanalization was defined as a thrombolysis in cerebral infarction score of 2b-3.

[Online survey of the organizational structures of emergency neurology in Germany].

In 2007, the first poll among neurologists provided some insight into the organizational structures of emergency neurology in Germany. Given that emergency neurology as well as emergency medicine in general have undergone substantial changes during the last decade, the subcommittee Neurological Emergency Medicine of the German Neurological Society conducted a follow-up study to explore current structures supporting neurological emergency medicine in German neurological hospitals. Between July and September 2016, an online questionnaire was e‑mailed to 675 neurologists in institutions participating in in-patient neurological care.

Clinical Significance of Intraluminal Contrast Enhancement in Patients with Spontaneous Cervical Artery Dissection: A Black-Blood MRI Study.

 Recent studies have suggested that intraluminal thrombi show contrast enhancement on carotid black-blood T1w MRI. The aim of this study was to evaluate the significance of intraluminal contrast enhancement (iCE) regarding symptom status in patients with spontaneous cervical artery dissection (sCAD).  33 consecutive patients (19 men) with sCAD received a brain MRI (DIFF, T2w, T2*w, FLAIR) and a multi-sequence 3T-MRI with fat-saturated high-resolution black-blood T1w-sequences pre- and post-contrast, contrast-enhanced MR angiography and TOF images of carotid and vertebral arteries.

Long-term Neurological Outcome and Quality of Life after World Federation of Neurosurgical Societies Grades IV and V Aneurysmal Subarachnoid Hemorrhage in an Interdisciplinary Treatment Concept.

Objective: Assessment of long-term outcome of WFNS IV and V aSAH patients.

Methods: Functional outcome and quality of life were assessed by the modified Rankin scale (mRS) and the 36-item short-form health survey in consecutively treated aSAH WFNS IV and V patients between 2005 and 2010.

Severe Cerebral Venous and Sinus Thrombosis: Clinical Course, Imaging Correlates, and Prognosis.

Background: Severe cerebral venous-sinus thrombosis (CVT) is a rare disease, and its clinical course, imaging correlates, as well as long-term prognosis have not yet been investigated systematically.

Methods: Multicenter retrospective study. Inclusion criteria were CVT, Glasgow coma scale ≤9, and treatment in the intensive care unit.

Regional differences in the cerebral blood flow velocity response to hypobaric hypoxia at high altitudes.

Symptoms of acute mountain sickness (AMS) may appear above 2,500 m altitude, if the time allowed for acclimatization is insufficient. As the mechanisms underlying brain adaptation to the hypobaric hypoxic environment are not fully understood, a prospective study was performed investigating neurophysiological changes by means of near infrared spectroscopy, electroencephalograpy (EEG), and transcranial doppler sonography at 100, 3,440 and 5,050 m above sea level in the Khumbu Himal, Nepal. Fourteen of the 26 mountaineers reaching 5,050 m altitude developed symptoms of AMS between 3,440 and 5,050 m altitude (Lake-Louise Score ⩾3).

[The course of early neurological rehabilitation in a patient with severe posterior reversible encephalopathy syndrome].

Posterior reversible encephalopathy syndrome (PRES) is widely held to be a benign and potentially reversible disease. However, severe cases have been described in the literature. Data on the long-term outcome of these severe cases are scarce.

Diagnostic and Prognostic Impact of pc-ASPECTS Applied to Perfusion CT in the Basilar Artery International Cooperation Study.

Background And Purpose: The posterior circulation Acute Stroke Prognosis Early CT Score (pc-APECTS) applied to CT angiography source images (CTA-SI) predicts the functional outcome of patients in the Basilar Artery International Cooperation Study (BASICS). We assessed the diagnostic and prognostic impact of pc-ASPECTS applied to perfusion CT (CTP) in the BASICS registry population.

Methods: We applied pc-ASPECTS to CTA-SI and cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) parameter maps of BASICS patients with CTA and CTP studies performed.

Severe depression as the sole symptom of affective focal status epilepticus.

Depression as well as fear, joy and anger have been described as the semiological features of focal epileptic seizures. When emotions present as the sole symptoms of epileptic seizures, they may easily be misdiagnosed as a psychiatric disorder. We describe a patient with affective focal status epilepticus, secondary to limbic encephalitis, in which depression was the only clinical manifestation.

Rehabilitation outcome of patients with severe and prolonged disorders of consciousness after aneurysmal subarachnoid hemorrhage (aSAH).

Objectives: Our objectives were to evaluate rehabilitation outcome of aSAH survivors with severe disorders of consciousness (DOC) and to examine potential predictors of long-term outcome. Severe DOC includes patients in a vegetative state (VS) and in a minimally conscious state (MCS).

Patients And Methods: This is a retrospective single-center cohort study of consecutive aSAH patients with severe and prolonged DOC upon admission to neurorehabilitation.

Hyperattenuated intracerebral lesions after mechanical recanalization in acute stroke.

Background And Purpose: Following mechanical recanalization of an acute intracranial vessel occlusion, hyperattenuated lesions are frequently found on postinterventional cranial CT. They represent either blood or-more frequently-enhancement of contrast agent. Here, we aimed to evaluate the prognostic value of these hyperattenuated intracerebral lesions.

Time-of-flight angiography: a viable alternative to contrast-enhanced MR angiography and fat-suppressed T1w images for the diagnosis of cervical artery dissection?

Objectives: To compare the use of an unenhanced high-resolution time-of-flight MR angiography sequence (Hr-TOF MRA) with fat-suppressed axial/coronal T1-weighted images and contrast-enhanced angiography (standard MRI) for the diagnosis of cervical artery dissection (cDISS).

Methods: Twenty consecutive patients (9 women, 11 men, aged 24-66 years) with proven cDISS on standard MRI underwent Hr-TOF MRA at 3.0 T using dedicated surface coils.

Early cranioplasty may improve outcome in neurological patients with decompressive craniectomy.

Primary Objective: Decompressive craniectomy is an effective therapy to relieve intractable intracranial hypertension following acute brain injury. However, little is known about the optimal timing for cranioplasties in the sub-acute phase. The objective of the present study was to analyse the effect of cranioplasty timing on neurological outcomes.

Aneurysmal subarachnoid hemorrhage in elderly patients: long-term outcome and prognostic factors in an interdisciplinary treatment approach.

The number of elderly patients with aneurysmal subarachnoid hemorrhage (SAH) is increasing with the aging of the population. However, management recommendations based on long-term outcome data and analyses of prognostic factors are scarce. Our study focused exclusively on elderly patients aged ≥ 60 years at the onset of SAH.

[Current registry studies of acute ischemic stroke].

Study registries offer the opportunity to evaluate the effects of new therapies or to observe the consequences of new treatments in clinical practice. The SITS-MOST registry confirmed the validity of findings from randomized trials on intravenous thrombolysis concerning safety and efficacy in the clinical routine. Current study registries concerning new interventional thrombectomy techniques suggest a high recanalization rate; however, the clinical benefit can only be evaluated in randomized, controlled trials.
