Multicenter Prospective Analysis of Hypertrophic Olivary Degeneration Following Infratentorial Stroke (HOD-IS): Evaluation of Disease Epidemiology, Clinical Presentation, and MR-Imaging Aspects
Introduction: Ischemic and hemorrhagic strokes in the brainstem and cerebellum with injury to the functional loop of the Guillain-Mollaret triangle (GMT) can trigger a series of events that result in secondary trans-synaptic neurodegeneration of the inferior olivary nucleus. In an unknown percentage of patients, this leads to a condition called hypertrophic olivary degeneration (HOD). Characteristic clinical symptoms of HOD progress slowly over months and consist of a rhythmic palatal tremor, vertical pendular nystagmus, and Holmes tremor of the upper limbs. Diffusion Tensor Imaging (DTI) with tractography is a promising m...

Hypertrophic olivary degeneration : Cause of new neurological symptoms after stroke.
CONCLUSION: Analysis of the dataset provided confirmation of the results in the literature that lesions within the Guillain-Mollaret triangle more often lead to HOD. Patients with corresponding symptoms should be closely observed over time with respect to the occurrence of corresponding clinical and imaging leading symptoms. Even though the named clinical symptoms are characteristic for HOD, in many cases the diagnosis is hampered and delayed by imprecise examination and misinterpretation of the symptoms. A logopedic examination using FEES in this collective often provided indicative information. Currently, no reliable dat...

An Unusual Cause Of Recurrent Ischemic Stroke: Trousseau's Syndrome From Gastric Cancer (P4.231)
CONCLUSIONS: Trousseau’s Syndrome must be considered in those presenting with recurrent strokes with an otherwise negative embolic work up especially in the elderly and those with cancer risk factors. It must prompt the clinician to look for an associated malignancy.Disclosure: Dr. JADEJA has nothing to disclose. Dr. Johnson has nothing to disclose. Dr. Soetanto has nothing to disclose.

Gastrointestinal Bleeding in Acute Ischemic Stroke: Recent Trends from the Fukuoka Stroke Registry
Background: Gastrointestinal (GI) hemorrhage is a potentially serious complication of acute stroke, but its incidence appears to be decreasing. The aim of this study was to elucidate the etiology of GI bleeding and its impact on clinical outcomes in patients with acute ischemic stroke in recent years. Methods: Using the database of the Fukuoka Stroke Registry, 6,529 patients with acute ischemic stroke registered between June 2007 and December 2012 were included in this study. We recorded clinical data including any previous history of peptic ulcer, prestroke drug history including the use of antiplatelets, anticoagulants, ...

Use of Apixaban and Warfarin in Patients Undergoing Procedures: Insights from ARISTOTLE (P5.002)
CONCLUSIONS: Procedures are common in patients with atrial fibrillation. The majority of procedures are non-major and non-emergent, and anticoagulation therapy is likely to be stopped peri-procedure. Overall and among emergent procedures, rates of clinical events in the first 30 days post-procedure were low and comparable between treatment groups.Study Supported by: Bristol-Myers Squibb Company and Pfizer Inc.

Summary of evidence-based guideline: Periprocedural management of antithrombotic medications in patients with ischemic cerebrovascular disease: Report of the Guideline Development Subcommittee of the American Academy of Neurology
Objective: To assess evidence regarding periprocedural management of antithrombotic drugs in patients with ischemic cerebrovascular disease. The complete guideline on which this summary is based is available as an online data supplement to this article. Methods: Systematic literature review with practice recommendations. Results and recommendations: Clinicians managing antithrombotic medications periprocedurally must weigh bleeding risks from drug continuation against thromboembolic risks from discontinuation. Stroke patients undergoing dental procedures should routinely continue aspirin (Level A). Stroke patients underg...
