Purpose: To report a case of spontaneously improved visual acuity in a patient with suprasellar meningioma.Case summary: A 55-year-old female presented with decreased visual acuity for 1 week. She had chronic headache and ocular pain. Her visual acuity of the right eye was 0.1 and temporal and inferior visual field defects were found. Relative afferent pupillary defect was observed in the right eye. On orbital magnetic resonance image, a homogenous enhancing mass with a broad dural base at the jugum sphenoidale was found. This was likely to represent a meningioma and was referred to neurosurgery. The patient refused the surgery and did not receive any treatment. After 1 month, the visual acuity of the right eye improved to 0.5. The improved vision remained until 6 months later. Conclusions Visual loss associated with meningioma can spontaneously improve and this should be considered when making diagnostic and treatment decisions for meningioma.

OBJECTIVE: We examined the difference in responses to donepezil between carriers and non-carriers of the A allele at the +4 position of the choline acetyltransferase (ChAT) gene in Koreans. METHODS: Patients who met the criteria for probable Alzheimer's disease (AD) (n=199) were recruited. Among these, 145 completed the 12-week follow-up evaluation and 135 completed the 26-week scheduled course. Differences and changes in the Korean version of the mini-mental state examination (MMSE-KC) score, Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Neuropsychological Assessment Battery (CERAD-K[N]) wordlist subtest score (WSS), CERAD-K(N) total score (TS), and the Korean version of geriatric depression scale (GDS-K) score between baseline and 12 weeks or 26 weeks were assessed by the Student's t-test. RESULTS: At 12 weeks, the changes in the MMSE-KC score, CERAD-K(N) WSS, and CERAD-K(N) TS from baseline were not significant between ChAT A allele carriers and non-carriers; however, at 26 weeks, these changes were significantly larger in ChAT A allele carriers than in non-carriers (p=0.02 for MMSE-KC and p=0.03 for CERAD-K(N) WSS respectively). CONCLUSION: Our findings in this study suggested that presence of the A allele at the +4 position of ChAT might positively influence the treatment effect of donepezil in the early stages of AD in Koreans.

Epithelial-myoepithelial carcinoma (EMC) is a low-grade malignant salivary gland neoplasm that was first described in 1972. EMC occurs in the older age group, there is a female predilection and mainly involves the parotid gland. Most authors recommend superficial parotidectomy as a treatment for low-grade malignant tumor in the superficial lobe of parotid gland. The treatment of epithelial-myoepithelial tumors typically includes surgical excision aimed at achieving a R0 resection. This paper reports a case of EMC of the parotid gland treated only by a conservational surgical excision. The lesion was exposed by the retromandibular approach and detached. After the parotid gland envelop was exposed, the mass was observed and was easy to remove due to capsulation. The preoperative diagnosis was a pleomorphic adenoma on the left parotid gland. The tumor was removed surgically with a conservative extracapsular dissection. The postoperative diagnosis was EMC, so superficial parotidectomy or radiation therapy was considered. Nevertheless, the patient was observed and no additional treatment was attempted because the patient was old and a successfully excision of the tumor had been achieved.

OBJECTIVES: We aimed to compare sleep factors including daytime sleepiness, sleep apnea and insomnia between mild cognitive impairment (MCI) patients and normal control (NC) subjects and to illustrate their relationship with neuropsychological function in the preclinical stage of dementia. METHODS: Epworth Sleepiness Scale (ESS), sleep apnea subscale of Sleep Disorders Questionnaire (SA) and questionnaire on insomnia were administered to community-dwelling elderly subjects above the age of 60. Both clinical and neuropsychological batteries of the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) assessment packet and Stroop Color and Word Test (SCWT) were done for each subject. Seventy seven NC subjects and 47 MCI patients were selected. RESULTS: In the NC group, ESS scores negatively correlated with Stroop interference (SI) scores. SA scores were negatively correlated with Stroop Color Word (SCW) and SI scores. In the MCI group, ESS scores negatively correlated with SCW scores, and SA scores had no correlation with each neurocognitive function test. CONCLUSION: Daytime sleepiness was associated with impaired executive function in community-dwelling normal elderly subjects and MCI patients. But the higher risk of SA was associated with decreased executive function only in normal elderly subjects.

BACKGROUND: H. pylori-associated gastrointestinal diseases have been widely recognized. The aim of this study was to investigate the seropositivity of H. pylori in health check-up subjects and to find out the relating factors. METHODS: From November 2004 through June 2005, total 7,676 health check-up subjects (age > or =20) responded to the self administered questionnaires. The prevalence of H. pylori was assessed by measuring anti-H. pylori IgG antibodies. RESULTS: The overall seropositivity was 56.7% in 7,676 and 1,137 (14.8%) has been found to have history of H. pylori eradication therapy. The seropositivity rate of H. pylori was 61.3% (2,653) in 4,328 subjects without history of H. pylori eradication and current gastrointestinal symptoms. Seroprevalence of H. pylori was significantly lower in 20~29 years old, female, high income and subjects from Seoul respectively. CONCLUSIONS: The seropositivity of H. pylori in 2004~2005 is found to be 61.3% in subjects without history of H. pylori eradication and current gastrointestinal symptoms. This seems to be lower than 66.9%, the seroprevalence rate in asymptomatic Korean population in the age of > or =16 years in 1998. This decrease might be caused by improvement of socioeconomic status.

BACKGROUND: Although several hospital-based stroke studies were published, there has not been any reliable data representing the clinical characteristics of stroke in Korea. We analyzed the clinical characteristics of patients with ischemic stroke registered in the Korean Stroke Registry (KSR), which is the largest prospective hospital-based nation-wide stroke registry in Korea. METHODS: The KSR provided standardized protocols for collecting data, which includes the data of demographics, subtypes of stroke, risk factors, and neurological outcome at discharge. The brain imaging studies, including CT or MRI, were performed in all cases. RESULTS: KSR registered 10,811 patients of acute ischemic stroke between Nov. 2002 and Jun. 2004. The large-artery atherosclerosis was the most common subtype (37.3%), followed by small vessel occlusion (30.8%). Hypertension (65.4%) was the most common risk factor, followed by smoking (34.5%) and diabetes (28.3%). Although most of the hypertensive and diabetic patients had been diagnosed before the stroke, less than 45.4% and 32.5% of them were under regular control. The steno-occlusive lesion of extracranial carotid artery was only 29.3% and the ratio of intra- to extracranial artery disease was more than 2 in KSR. Only 20.5% of patients were admitted within 3 hours after stroke onset and 2.1% were treated with intravenous thrombolysis. In-hospital case-fatality was 5.2%, which is relatively comparable to those of previous studies. CONCLUSIONS: The KSR provided informative data in understanding the clinical characteristics of ischemic stroke in Korea. Further analysis of KSR will facilitate clinical trials and development of guidelines for the management of stroke patients.

The authors report jerky seesaw nystagmus, extorsional downbeating in the right eye and intorsional upbeating in the left eye, in a patient with right internuclear ophthalmoplegia (INO). This pattern of nystagmus may occur by disrupting pathways from contralateral posterior and anterior semicircular canals by a lesion in the medial longitudinal fasciculus. Depending on damage to the pathways from contralateral vertical canals, various patterns of dissociated torsional-vertical nystagmus may accompany INO.

The purpose of this study is that evaluate the distribution and biological roles of TNF-a, interleukin-1beta(IL-1beta), interleukin-6(IL-6) and tissue inhibitors of metalloproteinase-1(TIMP-1) in the synovial fliud of patients with non-inflammatory chronic temporomandibular joint(TMJ) disorders in relation to pain during joint movements and magnetic resonance imaging(MRI) findings. TMJ synovial fluids aspirates were obtained from 36 patients (36 joints) with chronic TMJ disorders and from 8 controls(8 joints). Patients were divided to four groups. The control group was from healthy volunteers(8 joints), group I(18 joints) was patients with anterior disc displacement with reduction, group II(5 joints) was patients with disc displacement without reduction and group III (5 joints) was osteoarthritis. The TNF-alpha, IL-1beta and IL-6 levels in the aspirates were determined by using an enzyme-linked immunosorbent assay and the TIMP-1 level was measured by an enzyme immunoassay. Following examinations for pain during joint movements and MRI observations, these cytokines'level and frequencies of detection were compared. The level of IL-1beta was not significant different in all groups. but the level of TNF-alpha, IL-6 and TIMP-1 were significant different among groups. The level of IL-6 and TIMP-1 were correlated to pain during movement(p <0.01) and the level of TNF-a(p <0.05). Also, the level of IL-6 was correlated to the level of TIMP-1(p <0.01). Especially, The level of the TIMP-1 level was significantly correlated to the pain during movement and showed very high levle of Pearson's correlation coefficient (r=0.833)(p <0.001). The results indicated that the TNF-alpha, IL-6 and TIMP-1 levels in the TMJ aspirates of patients with chronic TMJ disorders have been raised. Especially, IL-6 and TIMP-1 were very high levels in the patients who were degraded in the TMJ. Also, TNF-alpha, IL-6 and TIMP-1 showed the significant correlation in the chronic temporomandibular joint disorders. Therefore I suggest that these cytokines were also correlated to the pain during movement in the chronic temporomandibular joint disorders.

The authors report jerky seesaw nystagmus, extorsional downbeating in the ipsilesional eye and intorsional upbeating in the contralesional eye, in a patient with internuclear ophthalmoplegia (INO) from focal pontine lesion. This pattern of nystagmus may occur by disrupting pathways from contralateral posterior and anterior semicircular canals by a lesion in the medial longitudinal fasciculus. Depending on the pathways involved, various patterns of dissociated torsional-vertical nystagmus may accompany INO.
