Segmental zoster paresis (SZP) is a clinically rare complication of herpes zoster. But it has not been reported that acute cerebral motor cortical infarction coincidentally occurred in SZP. A 86-year-old woman was admitted due to pain, tingling sensation, and weakness of left arm. She had an acute onset of pain and tingling sensation in left arm at first day, shoulder weakness at second day, and multifocal vesicles at fourth day. Deep tendon reflexes of left arm were decreased than right. Electromyography showed an axonal polyneuropathy at superior trunk level of left brachial plexus. Median and ulnar sensory evoked potential tests were normal. Brain MRI showed a high signal in right primary motor cortex on diffusion weighted image. We report a case of acute cerebral motor cortical infarction coincidentally occurred in SZP.

Background: Hypoglycemia is uncommon in people without diabetes. There have been only a few reports of cardiac arrest in conjunction with hypoglycemia in non-diabetic patients. Case Report: A 66-year-old man visited the emergency room with dizziness. He was a chronic alcoholic. Laboratory test showed no evidence of diabetes mellitus. Brain magnetic resonance imaging revealed a left cerebellar infarction. Abdomen computed tomography demonstrated liver cirrhosis with minimal ascites. During his hospital stay, he consumed only a small amount of food because of nausea and headache. On hospital day 4, he had a cardiac arrest after two seizure episodes. His blood glucose was 10 mg/dL. The combination of liver cirrhosis, renal failure and poor oral intake was presumed to be the causes of the severe hypoglycemia. Conclusion: We report a rare case of cardiac arrest occurring in conjunction with severe hypoglycemia in a non-diabetic patient with cerebral infarction.

Introduction: Stroke refers to a sudden brain disease that results in disorders in the anatomy of the brain. The cause is a sudden circulatory disorder of the cerebrovascular system that creates a consciousness disorder and hemiplegia. Despite aggressive treatment after the onset, stroke is a social problem because the patient has difficulty in recovering from sequelae that can include limb movement disorders, language disorders, and emotional disorders. In this study, we describe the effect of traditional Korean medicine treatment on the sequelae in a subacute cerebral infarction patient admitted to a Korean medical hospital. Case presentation: A 67-year-old male patient was diagnosed with cerebral infarction circa 2005, and his condition had not improved. Around March 15, 2018, he experienced the sudden onset of a cerebral infarction in his daily life. This was confirmed by a brain MRI, and he was hospitalized at other hospitals, but he showed no improvement. We conducted a manual muscle test (MMT) to evaluate the patient's exercise and strength. His gait level was measured to evaluate his degree of walking. He was treated with Bojungikgi-tang and acupuncture twice a day. After 34 days of inpatient treatment, the patient's exercise strength improved from Grade 2+~Grade 3 to Grade 3+ determined by the MMT, and his walking ability improved from Gait Level 3 to Gait Level 4. Conclusion: The findings of this study indicate that acupuncture and herbal medicine treatment can help treat patients with hemiplegia due to cerebral infarction.

Objectives : In condition of brain infarction, irreversible axon damage occurs in central nerve system(CNS), because gliosis becomes physical and mechanical barrier to axonal regeneration. Reactive gliosis induced by ischemic injury such as middle cerebral artery occlusion is involved with up-regulation of GFAP and CD81. The current study is to examine the effect of the Uncariae Ramulus et Uncus on CD81 and GFAP expression in the rat brain following middle cerebral artery occlusion. Methods : In order to study ischemic injuries on brain, infarction was induced by middle cerebral artery occlusion(MCAO) using insertion of a single nylon thread, through the internal carotid artery, into a middle cerebral artery. Cresyl violet staining, cerebral infarction size measurement, immunohistochemistry and microscopic examination were used to detect the expression of CD81 and GFAP and the effect on the infarct size and pyramidal cell death in the brain of the rat with cerebral infarction induced by MCAO. Results : The following results were obtained 1. Measuring the size of cerebral infartion induced by MCAO in the rat after injection of Uncariae Ramulus et Uncus showed the size was decreased. 2. Intravenous injection of Uncariae Ramulus et Uncus showed pyramidal cell death protection in the hippocampus in the MCAO rat. 3. Water extract injection of Uncariae Ramulus et Uncus decreased GFAP expression significantly in the MCAO rat. 4. Uncariae Ramulus et Uncus water extract decreased CD81 expression in the MCAO rat. 5. The administration of water extract of Uncariae Ramulus et Uncus induced up-regulation of c-Fos expression significantly compared with MCAO. 6. The admistration of water extract of Uncariae Ramulus et Uncus increased ERK expression significantly compared with MCAO. Conclusion : We observed that Uncariae Ramulus et Uncus could suppress the reactive gliosis, which disturbs the axonal regeneration in the brain of the rat with cerebral infaction after MCAO by controlling the expression of CD81 and GFAP. The effect may be modulated by the up-regulation of c-Fos and ERK. These results suggest that Uncariae Ramulus et Uncus can be a candidate to regenerate CNS injury.

Apraxia of phonation (AOP) has often been described as a feature of apraxia of speech or of severe non-fluent type of aphasia. Pure AOP is rare and, to our knowledge, only two cases have been reported. Brain lesion sites of the reported cases were not those sites known to be responsible for apraxia of speech. This study presents a case of AOP which resulted from the secondary stroke in the left corona radiata immediately following the first stroke in the left temporoparietal lobe. A 61-year old right-handed man shwoed a global type of aphasia after the first cerebral infarction, but was able to generate spontaneously some short fragments of speech. On the day after the first infarction, he suffered from the secondary infarction, leaving him a complete loss of voluntary phonation. He did not showed any significant change in language functions. Several occurrences of involuntary phonation were observed upon laughing or crying. He was also able to cough unintentionally. A vidoe-stroboscopic examination failed to reveal any evidence of structural and functional impairment in larynx. Although this case is not of pure form of AOP, AOP appeared after the secondary stroke without significant changes of language impairment since the first stroke. Therefore, AOP may be a consequence of the brain lesion from the secondary stroke even though we cannot rule out the possibility of an additive effect of the secondary to the first stroke.

A 69 year-old woman was admitted with sudden left facial weakness. She had no other neurologic deficit, except for left peripheral type facial palsy. She had a presumptive diagnosis of Bell's palsy. The blink test was indicative of left facial neuropathy due to left medullary lesion. Diffusion weighted (DWI) brain MRI demonstrated high signal signal lesion in left dorsolateral ponto-medullary junction. Apperant diffusion coefficient (ADC) brain MRI showed low signal lesion in the same area. We present an unusual case of ipsilateral peripheral facial palsy in dosolateral ponto-medullary infarction without other neurologic deficits.

Objectives : This study examined the neuroprotective effect of Hyulbuchookau-tang (血府逐瘀湯, HBCAT) against neural damage following global cerebral infarction. Methods : Sprague-Dawley rats were induced with global cerebral infarction by occlusion of the bilateral common carotid artery with hypotension (CCAO). The rats were divided into 3 groups. We treated extract of HBCAT to one group after operation (sample group), one group wasn't induced with ischemic damage after operation (sham group), and one group was induced with ischemic damage after operation (control group) but not treated. We observed neurological scores and cresyl violet-stained hippocampus CAl area, TUNEL-positive neurons, and Bax-positive neurons in brain regions. Results : HBCAT treatment after CCAO increased pyramidal neurons in CAl hippocampus induced by CCAO. HBCAT treatment after CCAO reduced Bax-positive neurons in CAl hippocampus of brain regions induced by CCAO. HBCAT treatment after CCAO wasn't effective for HSP70-positive neurons in CAl hippocampus induced by CCAO. Conclusions : These results suggest that HBCAT has a neuroprotective effect against global cerebral ischemia.

Objective : Hemorrhagic transformation (HT) can be occurred after acute cerebral infarction. HT can worse symptoms in severe cases and adversely affect long-term prognosis. As bone and vascular smooth muscle are composed of type 1 collagen, we aimed to identify a potential relationship between bone mineral density (BMD) and HT after acute cardioembolic stroke. Methods : As an indicator of BMD, we used mean frontal skull Hounsfield unit (HU) values on brain computed tomography (CT). Multivariative hazard ratios were calculated using Cox regression analysis to identify whether the osteoporotic condition was an independent predictor of HT after acute cardioembolic stroke. Results : This 11-year analysis enrolled 506 patients who diagnosed as acute cardioembolic infarction. The first tertile of skull HU value was an independent predictor of HT development compared to the third tertile (hazard ratio, 2.12; 95% confidence interval, 1.13-3.98; p=0.020). We observed no interactions between age and skull HU with respect to HT statistically. Conclusion : The results of this study revealed an association between osteoporotic conditions and HT development after acute cardioembolic stroke. A convenient method to measure the cancellous bone HU value of the frontal skull using brain CT images may be useful for predicting HT in patients with acute cerebral infarction.

Differentiating central vestibulopathy from more common vestibular disorders is crucial because it often necessitates different treatment strategies, and early detection can help to minimize potential complications. Isolated nodular infarct is one of the central brain lesions that can mimic peripheral vertigo. We present a case of isolated nodular infarct that had been misdiagnosed as vestibular neuritis on the contralateral side at the initial evaluation. The patient was successfully treated with anticoagulants and antihyperlipidemic agents. Clinicians should keep in mind that some causes of central vertigo mimic peripheral vestibulopathy at the early stage.
