The pEGASUS-HPC stent system for intracranial arterial stenosis: a single-center case series.

Background: Intracranial arterial stenting is a technique for the treatment of symptomatic stenosis. In this single-center retrospective case series we evaluated a novel low profile laser-cut stent with an antithrombogenic hydrophilic polymer coating (pEGASUS-HPC, Phenox GmbH, Bochum, Germany) for the treatment of intracranial stenosis in the setting of acute ischemic stroke and elective cases.

Methods: All patients treated with pEGASUS-HPC for one or more intracranial arterial stenoses at our institution were retrospectively included.

Thrombectomy With the pRESET vs Solitaire Stent Retrievers as First-Line Large Vessel Occlusion Stroke Treatment: A Randomized Clinical Trial.

Importance: Stent retriever-based thrombectomy is highly beneficial in large vessel occlusion (LVO) strokes. Many stent retriever designs are currently available, but comparison of these technologies in well-conducted studies is lacking.

Objective: To determine whether thrombectomy for LVO stroke with the pRESET stent retriever is noninferior to treatment with the Solitaire stent retriever.

Alien hand syndrome in ruptured aneurysms: case report and review of the literature.

Alien hand syndrome is a rare condition associated with lesions of the corpus callosum and of the supplementary motor area, which can be caused by ruptured cerebral aneurysms. We present a novel case of a patient with a subarachnoid haemorrhage from an aneurysm of the anterior communicating artery who developed alien hand syndrome and intermanual conflict. In addition, we performed a systematic literature search and evaluated data on clinical presentation, treatment and radiological findings from relevant papers.

Functional Aplasia of the Contralateral A1 Segment Influences Clinical Outcome in Patients with Occlusion of the Distal Internal Carotid Artery.

Background: The importance of an A1 aplasia remains unclear in stroke patients. In this work, we analyze the impact of an A1 aplasia contralateral to an acute occlusion of the distal internal carotid artery (ICA) on clinical outcomes. Methods: We conducted a retrospective study of consecutive stroke patients treated with mechanical thrombectomy at 12 tertiary care centers between January 2015 and February 2021 due to an occlusion of the distal ICA.

Tic Reduction in Adult Onset Gilles De La Tourette Syndrome Using as Required Nabiximols Spray.

Background: Tourette syndrome (TS) manifests with motor and vocal tics that can reach disabling intensity. Established therapies may show insufficient relief or side effects. Cannabinoids have demonstrated therapeutic potential in small studies.

[Double vision and a wrong track].

A 72-year-old woman presented to our emergency centre with acute horizontal diplopia. Neurological examination revealed an isolated abducens nerve paresis on the left. Hilar enlargement seen on the chest x-ray and an elevated serum ACE level led us to suspect sarcoidosis, but the patient declined further evaluation.

Postoperative MRI localisation of electrodes and clinical efficacy of pallidal deep brain stimulation in cervical dystonia.

Introduction: Pallidal deep brain stimulation (DBS) has been shown to be effective in cervical dystonia (CD) with an improvement of about 50-60% in the Toronto Western Spasmodic Torticollis Rating (TWSTR) Scale. However, predictive factors for the efficacy of DBS in CD are missing with the anatomical location of the electrodes being one of the most important potential predictive factors.

Methods: In the present blinded observational study we correlated the anatomical localisation of DBS contacts with the relative clinical improvement (CI %) in the TWSTR as achieved by DBS at different pallidal contacts in 20 patients with CD.

Spasticity treatment with onabotulinumtoxin A: data from a prospective German real-life patient registry.

This study aimed at providing real-life baseline, injection and outcome data for the treatment of various forms of spasticity with onabotulinumtoxin A in Germany. Prospective data were collected in an open multicenter patient registry from 2005 until 2010, encompassing the experience of ten specialized German centers in the treatment of spasticity using onabotulinumtoxin A in 508 patients with a total of 2005 treatment sessions. Disease entities comprised spasticity following stroke (both ischemic and hemorrhagic), traumatic brain injury, multiple sclerosis, cerebral palsy, and anoxia.

No correlation of substantia nigra echogenicity and nigrostriatal degradation in Parkinson's disease.

Background: Substantia nigra hyperechogenicity assessed by transcranial sonography is a typical finding in up to 90% of patients with idiopathic Parkinson's disease, although its value as a surrogate marker for disease progression in Parkinson's disease is controversial. (123) I-FP-CIT-single photon emission computed tomography (SPECT) represents an established paraclinical surrogate marker to quantify the nigrostriatal dopaminergic deficit in Parkinson's disease. Whereas most studies found no correlation between extent of substantia nigra echogenicity and the putaminal FP-CIT binding ratio, a more recent analysis reported opposite results.

Influences of levodopa on adipose tissue and skeletal muscle metabolism in patients with idiopathic Parkinson's disease.

Objective: The substantial weight loss in Parkinson's patients may be related to direct influences of levodopa treatment on fat mobilization/oxidation. We assessed systemic and local metabolic responses to levodopa/benserazide in patients with idiopathic Parkinson's disease.

Methods: We studied 10 Parkinson's disease patients and examined adipose tissue and skeletal muscle metabolism directly with microdialysis.

Brain parenchyma sonography and 123I-FP-CIT SPECT in Parkinson's disease and essential tremor.

We aimed to investigate the accuracy of transcranial brain parenchyma sonography (TCS) for differentiation between idiopathic Parkinson's disease (PD) and essential tremor (ET) in comparison to (123)I-FP-CIT SPECT (FP-CIT SPECT). Seventy-four patients, in whom PD or ET was suspected on the basis of clinical criteria, were analyzed. The echogenicity of the substantia nigra (SN) and the striatal binding of dopamine transporters (DAT) were evaluated by TCS and FP-CIT SPECT, respectively.
