RESUMO
BACKGROUND: At most centers, general anesthesia (GA) has been preferred for endovascular treatment (EVT) of ruptured intracranial aneurysms (RIAs). In this study, we analyzed procedural results, clinical outcomes, and follow-up angiographic findings for patients undergoing EVT for RIA under local anesthesia (LA) with conscious sedation (CS). METHODS: We retrospectively evaluated 308 consecutive patients who underwent EVT for RIAs at a single institution between June 2009 and February 2017. EVT under LA with CS was considered for all patients with aneurysmal subarachnoid hemorrhage, regardless of Hunt and Hess (HH) scale score. RESULTS: EVT was performed for 320 aneurysms in 308 patients with subarachnoid hemorrhages. The mean patient age was 55.5±12.6 years. Moderate (III) and poor (IV, V) HH grades were observed in 75 (24.4%) and 77 patients (25%), respectively. Complete occlusion immediately after EVT was achieved for 270 (84.4%) of 320 aneurysms. Thromboembolic complications and intraprocedural ruptures occurred in 25 (7.8%) and 14 cases (4.3%), respectively. The morbidity rate at discharge (as defined by a modified Rankin scale score of 3 or greater) was 27.3% (84/308), while the mortality rate was 11.7% (36/308). Follow-up angiographic results were available for 210 (68.1%) of 308 patients. Recanalization was observed in 64 (29.3%) of 218 aneurysms in 210 patients. CONCLUSION: Based on our experience, EVT for RIAs under LA with CS was feasible, regardless of the clinical grade of the subarachnoid hemorrhage. Complication rates and follow-up angiographic results were also comparable to those observed when GA was used to perform the procedure.

Multifocal acquired demyelinating sensory and motor neuropathy (MADSAM) is a peripheral neuropathy characterized by multifocal weakness and associated sensory impairment. MADSAM is associated with multifocal persistent conduction block and other signs of demyelination. The incidence of cranial nerve involvement in MADSAM was recently reported to be approximately 15%. However, reports of hypoglossal neuropathy occurring in MADSAM are rare. Unilateral hypoglossal neuropathy in MADSAM is usually misdiagnosed as motor neuron disease. We report a patient with MADSAM presenting with tongue hemiatrophy.

Crossed cerebellar diaschisis (CCD) is known to be due to a contralateral supratentorial lesion decreasing blood flow and the metabolism in a cerebellar hemisphere. Arterial spin labeling (ASL) is an imaging technique that utilizes arterial blood water as a tracer for quantifying the regional cerebral blood flow in magnetic resonance imaging (MRI). This case was a patient with simple partial status epilepticus (SPSE) and CCD confirmed by ASL-perfusion MRI. Controlling the SPSE resulted in improvement of CCD being observed in the follow-up ASL-perfusion MRI.

A cavernous angioma (CA) and a developmental venous anomaly may consist a mixed vascular malformation (MVM). Two bleeding foci were observed in a MVM of a man with epilepsy. The hemodynamic association between the two foci was not clear. An advance of neuroimaging may enhance the susceptibility of detection of MVMs. We should consider a MVM when a daughter bleeding focus occurs near the main bleeding focus associated with a CA.

Background: Hypertension results from an impaired baroreceptor reflex and enhanced sympathetic activity. The prevalence of hypertension differs among ethnicities and is more frequent in South Asians than in Caucasians, suggesting that baseline autonomic nervous system functions and their regulation may also differ among ethnic groups. In most studies, the reference values for clinical autonomic function tests are obtained from heterogeneous ethnic populations, or ethnic factors are not considered in the study design. Obtaining reference data in a homogenous ethnic group and comparing them within various ethnic groups could be helpful to detect ethnic differences in autonomic functions. The aim of this study was to identify normative reference values for standard autonomic reflex measurements in a homogeneous Korean population. Methods: A total of 181 healthy Korean volunteers (age, 20–74 years) underwent standard autonomic function tests: heart rate difference during deep breathing, Valsalva maneuver, and the quantitative sudomotor axon-reflex test. Mean and 5th and 95th percentile values were obtained for each age group. We also analyzed factors (age, sex, and body mass index) that can influence autonomic functions. Results: The heart rate difference during deep breathing and expiratory-inspiratory ratio were higher in males than in females and were inversely related to age. The Valsalva ratio was inversely related to age. Males had higher sweat volumes at all body areas evaluated than those of females, and only forearm sweat volume was significantly different between the age groups. Conclusions: Cardiovagal function was affected by age and sex in Koreans. Sudomotor function was affected by sex, and only forearm sweat volume was affected by age and sex. These results represent preliminary normative clinical autonomic data in a Korean population comprised of a single ethnicity

Controlled-release carbamazepine (CBZ) could be more harmful than the regular form in special situations due to their respective biochemical characteristics. When primary treatment is not effective in acute intoxication, extracorporeal treatment (ECTR) could be an option. We recently applied ECTR to a patient with combined intoxication of topiramate and controlled-release CBZ who deteriorated despite receiving primary treatment. The patient improved after administering ECTR. Early ECTR intervention may be beneficial for the treatment of CBZ intoxication, especially of the controlled-release form.

Amyloidosis is a systemic disorder associated with clonal plasma cell dyscrasia. Nephrotic syndrome, congestive heart failure, autonomic and peripheral neuropathy is often associated features in amyloidosis. Early diagnosis is most important because of different prognosis by stage. The diagnosis can be delayed since symptoms of amyloidosis may vary or nonspecific. We describe a patient of myeloma-associated amyloidosis, who showed orthostatic intolerance as the first symptom of the disease.

Objectives: White matter hyperintensities are known to influence dementia in Alzheimer’s disease. Genetic components are suggested as putative risk factors for vascular pathology and cognitive decline. This study aimed to determine whether there is an association between candidate genetic polymorphisms and the severity of white matter hyperintensities in patients with Alzheimer’s disease. Methods: Seventy-five patients diagnosed with Alzheimer’s disease underwent genetic tests for specific alleles of apolipoprotein E, angiotensin-converting enzyme, and methylenetetrahydrofolate reductase. All patients underwent brain magnetic resonance imaging scans and neuropsychological tests. The severity of white matter hyperintensities was semiquantified using the CREDOS rating scale, and patients were divided into three groups according to their rating. Results:The severity of white matter hyperintensities was related to age and hypertension. However, none of the gene polymorphisms we tested was found to be associated with the severity of white matter hyperintensities. Conclusion:The genetic polymorphisms found in apolipoprotein E, angiotensin-converting enzyme and methylenetetrahydrofolate reductase did not contribute to white matter hyperintensities in Alzheimer’s disease.Only age and hypertension factors were found to be contributory to white matter hyperintensities.

Artemisia annua is a wormwood. Because it may induce Cytochrome P450 2C19 enzyme, Artemisia annua may have an influence on antiepileptic drugs which are substrates for the enzyme. This influence may negatively affect seizure control of epilepsy patient. We present a patient whose seizures were induced by Artemisia annua, despite he was taking levetiracetam which is not a substrate for the hepatic enzyme. Therefore there would be another mechanism of seizure induction of Artemisia annua besides hepatic metabolism.

The prevalence of Alzheimer's disease (AD) is increasing as the global population ages. Currently available treatments for AD target cholinergic and glutamatergic neurotransmission. There have been modest symptomatic effects, but disease modifying effects have not been accomplished. This is even true of clinical trials of bapineuzumab and solanezumab, two humanized monoclonal antibodies that bind amyloid. Therefore, innovations in clinical trial designs are necessary, including revised diagnostic criteria and treatment at the earliest stages of AD. Several prevention trials started in 2013, emphasizing these innovative principles of clinical trial design. In this review, we will discuss the paradigm shift for AD clinical treatment trials and ongoing preventative trials.

Dissecting aneurysm of the intracranial arteries is a rare cause of stroke. This condition may induce both ischemic stroke and hemorrhagic stroke by occlusion of the parent artery via direct distortion and stretching, compression secondary to growth of the aneurism, and distal embolization of any intra-aneurysmal thrombi. A patient with an infarction in the right middle cerebral artery territory and a mass lesion located in the right basal ganglia and temporal lobe was examined in this study. The consequent workup suggested that the mass lesion was a huge dissecting aneurysm that had resulted in a cerebral infarction.

Parry-Romberg syndrome, or progressive facial hemiatrophy, is a rare and acquired neurocutaneous disease of unknown etiology that is classically characterized by progressive and self=limited atrophy of the skin, subcutaneous tissues, and underlying bone structures. Ophthalmic involvement is reportedly not uncommon, and the most common ocular finding is enophthalmos. Here we report a 46=year=old woman with Parry=Romberg syndrome who presented with intermittent exotropia of the right eye. To the best of our knowledge, this is the first description of intermittent exotropia in a patient with Parry-Romberg syndrome.

Hanging is one of the most common causes of suicidal death. Most hanging victims are dead when discovered, and hence there are few reports of near-hanging patients or survivors of a hanging injury. We experienced a patient with motor aphasia who survived a hanging injury. Consecutive workup revealed a cerebral infarction on the left middle cerebral artery territory, which was considered to be the cause of his aphasia.

Brainstem infarction secondary to basilar artery occlusion often causes very-severe and life-threatening neurological conditions. For better recovery, early diagnosis is essential; however, this is not always easy because of ambiguous symptoms and limited information in some cases. We experienced two patients with basilar artery occlusion who presented with convulsive-like movements as an initial manifestation.
