BACKGROUND: Endoscopic thoracic sympathectomy (ETS) was performed to cure palmar hyperhidrosis (PH). After ETS, blood pressure decreased, and cerebral flow velocity increased within 1 month. However, no studies distinguish between subsequent ischemic and hemorrhagic stroke following ETS for PH. The association between stroke type and PH after ETS must be evaluated. METHODS: We surveyed newly diagnosed patients with PH using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic code 708...

BACKGROUND: There is no agreement for the etiologic classification of patients with intracerebral hemorrhage (ICH). In a series of patients with ICH, we performed a randomized head-to-head comparison between the two recently proposed etiologic classification systems. METHODS: We evaluated patients registered in a prospective database of consecutive patients. A simplified H-ATOMIC classification defines 8 categories: hypertension, amyloid, tumor, oral anticoagulants, malformation, infrequent, cryptogenic, and combination...

Oculomeningovascular amyloidosis is a variant of transthyretin (TTR) amyloidotic polyneuropathy, which is associated with blindness and brain ischemia, microhemorrages, and siderosis due to prominent production of the abnormal TTR in the eye and in the choroid plexuses. Tafamidis is a TTR stabilizer that is orally administered and, by interfering with amyloid fibril formation and deposition, is capable of slowing progression of TTR polyneuropathy and of early-stage cardiomyopathy. However, the ocular manifestations of amyloid deposition progressed despite tafamidis therapy in Val30Met TTR amyloidosis, and the effects of tafamidis on meningovascular amyloidosis are unknown...

BACKGROUND: There is a widespread belief that Asians are more susceptible to hemorrhagic transformation (HT) after receiving recombinant tissue-type plasminogen activator (rt-PA) for acute ischemic stroke (AIS). However, this has not been examined in clinical practice. This study aims to compare the incidence of symptomatic hemorrhagic transformation (SHT) among thrombolysis-treated AIS patients in China and in the United States. METHODS: We compared 212 consecutive patients receiving thrombolysis within 4...

OBJECTIVES: Prehospital delay is a challenge for stroke treatment and the delivery of time-critical treatments. Few studies have examined secular trends in prehospital delay, and results vary. This study investigates how prehospital delay among Norwegian stroke patients has changed over the last 2 decades. METHODS: We compared time from symptom onset to admission in 2 cohorts of stroke patients admitted to Akershus University Hospital, Norway, in 1994 (n = 550) and 2012 (n = 522), and constructed predictive models for arrival within 3 hours for each cohort...

BACKGROUND: The antiplatelet drug cilostazol decreases the risk of ischemic stroke recurrence in patients with chronic cerebral infarction. Additionally, cilostazol reduces the occurrence of pneumonia in these patients. The purpose of this study was to investigate whether cilostazol is effective for preventing pneumonia in patients with acute cerebral infarction. MATERIALS AND METHODS: A total of 199 consecutive Japanese patients with noncardioembolic acute cerebral infarction, who visited our hospital from January 2010 to April 2016, were retrospectively assessed by using medical records...

BACKGROUND: Several studies have shown a linkage between intraplaque neovascularization (IPN) and plaque instability. Although contrast-enhanced ultrasonography (CEUS) may help visualize IPN in the carotid artery, its benefits are limited in Japan, where there is no health insurance coverage for contrast agents in medical imaging. Superb microvascular imaging (SMI), however, enables the depiction of low-velocity blood flow. The current study compares the diagnostic accuracy of SMI and CEUS in the evaluation of IPN...

REVIEW
Deborah K Rose, Barak Bar
Vitamin K antagonists (VKAs), such as warfarin, have been used for thromboprophylaxis and for the treatment of thromboembolic events in patients with nonvalvular atrial fibrillation for over 60 years. The increasing use of direct oral anticoagulants (DOACs) in recent years has shown greater advantages and safer use over VKA, including reduced bleeding, fewer drug interactions, no food interactions, a quick onset and offset of activity, and predictable dose-response properties. Despite their advantages, there are a couple of major limitations that raise concerns among clinicians, including the need for more coagulation assays to monitor their effects and more specific reversal antidotes in life-threatening circumstances of bleeding...

BACKGROUND: Accumulating studies have reported that there is an association between the Ring finger protein 213 (RNF213) p.R4810K (rs112735431, c.14576G>A) single nucleotide polymorphism and the predisposition of moyamoya disease (MMD), intracranial major artery stenosis/occlusion (ICASO), quasi-moyamoya disease (quasi-MMD), and other vascular diseases. However, to this day, analyses about this association have remained scarce in the literature. We attempted to conduct a meta-analysis to systematically summarize and clarify the issue...

BACKGROUND AND PURPOSE: Muscle and bone form a functional unit. Residual physical poststroke impairments such as muscle weakness, spasticity, and decrease in function can promote metabolic bone changes. Moreover, muscle strength can influence this process. Thus, the purpose of the present study was to investigate bone volume and mobility performance in subjects with chronic hemiparesis post stroke. METHODS: A cross-sectional study was performed on 14 subjects post stroke who were paired with healthy controls...

Left ventricular thrombi are mostly seen in the akinetic segments of left ventricle and warfarin is the golden standard treatment. In our case, a 67-year-old male patient with ischemic dilated cardiomyopathy and atrial fibrillation was under warfarin treatment, but due to fluctuations in international normalized ratio, warfarin was discontinued and changed to rivaroxaban (20 mg once a day). He had a fixed thrombus measuring 1.80 × 1.12 cm2 in the left ventricle under warfarin treatment before rivaroxaban use...
