Optic perineuritis is characterized by optic disc swelling with normal visual acuity, pupillary responses and intracranial pressures, and normal visual fields except for an enlarged blind spot that may be confused with papilledema caused by brain tumor or pseudotumor cerebri. It is a rare manifestation of neurosyphilis, and it is thought to represent an extension of basal meningeal inflammation to the optic nerve sheaths. Serum VDRL tests are negative in a significant proportion of patients with late syphilis, particularly in those with neurosyphilis(seronegative syphilis). We present a case of optic perineuritis associated with seronegative neurosyphilis.

BACKGROUND: The waist-to-height ratio (WHtR) is an easy and inexpensive adiposity index that reflects central obesity. In this study, we examined the association of baseline WHtR and progression of coronary artery calcification (CAC) over 4 years of follow-up in apparently healthy Korean men. METHODS: A total of 1,048 male participants (mean age, 40.9 years) in a health-screening program in Kangbuk Samsung Hospital, Seoul, Korea who repeated a medical check-up in 2010 and 2014 were recruited. Baseline WHtR was calculated using the value for the waist in 2010 divided by the value for height in 2010. The CAC score (CACS) of each subject was measured by multi-detector computed tomography in both 2010 and 2014. Progression of CAC was defined as a CACS change over 4 years greater than 0. RESULTS: During the follow-up period, progression of CAC occurred in 278 subjects (26.5%). The subjects with CAC progression had slightly higher but significant baseline WHtR compared to those who did not show CAC progression (0.51+/-0.04 vs. 0.50+/-0.04, P<0.01). The proportion of subjects with CAC progression significantly increased as the baseline WHtR increased from the 1st quartile to 4th quartile groups (18.3%, 18.7%, 28.8%, and 34.2%; P<0.01). The risk for CAC progression was elevated with an odds ratio of 1.602 in the 4th quartile group of baseline WHtR even after adjustment for confounding variables (95% confidence interval, 1.040 to 2.466). CONCLUSION: Increased baseline WHtR was associated with increased risk for CAC progression. WHtR might be a useful screening tool to identify individuals at high risk for subclinical atherosclerosis.

From Mar. 1985 to Dec. 1992, 170 cases of osteosarcoma, which were proved histologically were admitted in our department at least one time. Among them we analysed 89 cases of Ennekings stage IIB who took limb-salvage(54) or amputation(35) and followed our protocol, with non-randomized retrospective study. The average age of the 89 patiens was 17.0 years(7 to 57). Fifty-four cases of salvage group took neoadjuvant chemotherapy, 35 cases of amputation group took neoadjuvant or adjuvant chemotherapy. The result revealed prevalences of 2/54, 0/35 as to local recurrence; 15 of 54, 17 of 35 as to metastasis; 14 of 54, 15 of 35 as to death. Of the 2 patients who had a local recurrence, one died of metastasis and the other was lost follow up. According to Kaplan-Meier's plot 5-year continuously disease free survival rate for whole 89 cases of stage IIB was 43.1%, for salvage group 56.4%, for amputation group 34.0%. There were no signifcant difference in survival rate between salvage and amputation groups(p>0.05, by log-rank test). This result means the limb-salvage operation for Enneking's stage IIB osteosarcoma does not hinder patients survival.

Cluster headache is a unique primary headache disorder characterized by unilateral severe orbital pain with ipsilateral autonomic symptoms. Symptomatic cluster headache can be caused by variable diseases, such as cerebral aneurysm, arteriovenous malformation, cerebral venous thrombosis, carotid dissection, pituitary tumor, and meningioma. We report a 33-year-old woman with parasellar meningioma mimicking cluster headache. After Novalis stereotactic radiosurgery, pain attacks disappeared.

Periprocedural management of antithrombotics for gastroenterological endoscopy is a common clinical issue. To decide how to manage the use of antithrombotics in patients undergoing endoscopy, the risk for hemorrhage and thromboembolism during the procedure must be considered. For low-risk procedures, no adjustments in antithrombotics are needed. For high-risk procedures with a low thromboembolic risk, discontinuation of warfarin at 5 days, and clopidogrel at 5 to 7 days before the procedure has been recommended. However, it is better to continue aspirin use even during high-risk procedures. A heparin bridging therapy may be considered before endoscopy in patients with a high thromboembolic risk. The management of patients taking antithrombotics remains complex, especially in high-risk settings.

BACKGROUND: Inflammatory mechanisms play an important role in acute brain ischemia, and they contribute to the functional outcome. The neutrophil-to-lymphocyte ratio (NLR) has recently been described as a predictor of clinical outcomes in patients with acute coronary syndrome. This study assessed the clinical significance of NLR as a new predictor of the outcome in patients with acute ischemic stroke. METHODS: The study included 371 patients diagnosed as acute ischemic stroke within 48 hours after the onset. All subjects were divided into three groups according to tertiles of the NLR in the initial blood test. Functional outcomes were divided into two groups at 3 months and 1 year after stroke onset: favorable (mRS 0~2) or unfavorable (mRS 3~6). RESULTS: The proportion of patients with mRS 0~2 (favorable outcome) decreased as the NLR increased from the first tertile to the third tertile at discharge (74%, 62.9 and 49.2, p<0.001) and at 3 months (74%, 66.9 and 42.7, p<0.001) and 1 year (67.5%, 64.5 and 41.1, p<0.001) after stroke. NLR was higher in patients with an unfavorable outcome than in those with a favorable outcome (3.88 vs. 2.27 at 3 months, p<0.01; 3.67 vs. 2.31 at 1 year, p<0.001). Multivariate analysis revealed that the significant predictors of an unfavorable outcome at 3 months were NLR in the highest tertile (OR 2.28, 95% CI 1.13~4.60), age (OR 1.04, 95% CI 1.01~1.07), and NIHSS score (OR 1.27, 95% CI 1.18~1.36) at admission. CONCLUSIONS: NLR at admission can be used as a predictor of functional outcome at 3 months after ischemic stroke.

OBJECTIVE: In 2013, a new risk calculator known as the Pooled Cohort Equation (PCE) was introduced with the new cholesterol guideline. We aimed to calculate the 10-year atherosclerotic cardiovascular disease (ASCVD) risk using PCE in non-diabetic Korean subjects with glycated hemoglobin (HbA1c) lower than 6.5%. METHODS: A total of 17,519 participants were evaluated in a health screening program. The 10-year ASCVD risk was calculated using the PCE. Subjects with underlying diabetes or HbA1c > or =6.5% were excluded. Subjects were divided into four groups according to fasting blood glucose (FBG) and HbA1c levels: FBG <100 mg/dL, 100< or =FBG<110 mg/dL, 110< or =FBG<120 mg/dL, and FBG > or =120 mg/dL; HbA1c <5.5%, 5.5%< or =HbA1c<5.6%, 5.6%< or =HbA1c<5.8%, and HbA1c > or =5.8%. RESULTS: The mean 10-year ASCVD risk significantly increased as FBG increased from <100 mg/dL to >120 mg/dL in the four divided groups (2.6%, 3.3%, 3.8%, 4.1%; p<0.01), and as HbA1c increased from <5.5% to >5.8% (2.4%, 2.7%, 3.0%, 3.6%; p<0.01). The odds ratio for 10-year ASCVD risk > or =10% significantly increased from group I to IV according to FBG and HbA1c levels after adjusting for age, body mass index and fasting insulin level (1.187, 1.753, and 2.390 vs. 1.0 in the lowest FBG group; 1.626, 1.574, and 1.645 vs. 1.0 in the lowest HbA1c group). CONCLUSION: The 10-year ASCVD risk calculated using the PCE significantly increased as the FBG and HbA1c increased even in Korean subjects without underlying diabetes.

Central pontine myelinolysis (CPM) is well-recognized osmotic demyelination syndrome that is related to various conditions such as rapid correction of hyponatremia and chronic alcoholism. Acute ataxia as a sole clinical sign in CPM is rare. We report a case of a 59-year-old man with dysarthria, intention tremor, and a significant gait ataxia starting after alcohol withdrawal, with radiological evidence of CPM. CPM should be included in the differential diagnosis of alcoholic patients who develop a sudden ataxia. Chronic alcohol abuse is one of the most commonly encountered predisposing factors. Alcohol withdrawal represents an additional vulnerability factor, being responsible for electrolyte imbalances which are not always demonstrable but are certainly involved in the development of CPM.

Hemichorea have been reported in patients with nonketotic hyperglycemia. Usually, hemichorea and hyperglycemia are concomitant. A 73-year-old woman was admitted for investigation of an acute hemichorea. T1-weighted brain magnetic resonance imaging showed hyperintensity in the right putamen. Although she was a diabetic patient, she had no hyperglycemia. Interestingly, 4 weeks earlier, the patient was admitted due to nonketotic hyperglycemia. However, there were no hemichorea at that time. Although pathophysiologically controversial, a delayed hemichorea without nonketotic hyperglycemia should be considered as one of many different causes when evaluating acute hemichorea in diabetic patients.

Even a single brain infarct can cause dementia when it occurs in functionally critical areas of the brain. A 71- year-old female developed sudden cognitive impairment without any other focal neurologic deficits. A brain MRI revealed a bilateral anterior fornix infarction. Neuropsychological evaluation revealed verbal and visual memory deficits, visuospatial dysfunction, and frontal executive dysfunction. The cognitive impairment did not improve for 3 months and the patient showed impairments in daily activities. We report a patient who demonstrated strategic infarct dementia after a bilateral anterior fornix infarction.
