Cerebral arterial embolism which resulted in total occlusion of right proximal middle cerebral artery was occured in 33 years old female patients with severe mitral stenosis and atrial fibrillation during percutaneous mitral balloon valvuloplasty(PMV). The occluded artery could be detected by transfemoral carotid angiography and recanalized immediately by intra-arterial infusion of urokinase. There were no cerebral hemorrhage by CT scan after intra-arterial urokinase infusion and the patients discharged without any neurologic sequale 7 days after thrombolysis. We report a case of successful recanalization with intraarterial infusion of urokinase in patient with cerebral arterial embolism occurred during PMV.

BACKGROUND: Food restriction has been reported to ameliorate diabetes and obesity. In this study, we examined the effects of the food restriction on phenotypes of TALLYHO/JngJ (TH) mouse, a recently developed diabetic model animal. METHODS: 3 week-old TH mice were divided into 2 groups (n = 20 each for food-restricted (THR) and free-fed (THF)) and THR mice were fed the same amount of food as normal control mice (C57BL/6, n = 20). Body weight was weekly monitored till 14 weeks of age. The half of animals were sacrificed at 8 weeks of age, and liver, kidney, and fat weight were measured. The histopathology of liver and brown fat tissues and mRNA expression of leptin in adipose tissue were analyzed. The oral glucose tolerance test and insulin resistance test was done at 14 weeks of age. The plasma concentrations of glucose, free fatty acid, triglyceride, cholesterol and leptin were analyzed. RESULTS: The THR mice had lower body weights than the THF mice, similar to C57BL/6 mice, with reduced fat deposition in liver and brown fat tissue. The plasma levels of glucose, triglyceride and free fatty acid were decreased in the THR group. The THR mice, however, carried more fat than normal mice, with increased plasma leptin concentration and leptin mRNA expression in fats and no alteration in plasma cholesterol levels. Furthermore, the THR mice revealed glucose intolerance with impaired after-meal insulin secretion and slight insulin resistance CONCLUSION: The food restriction apparently ameliorated the obesity and diabetic phenotypes of TH mice. However, plasma concentration of cholesterol were not improved in THR mice with increased adiposity index and glucose intolerance, suggesting the genetically prone tendency of obesity and diabetes development in TH mice possibly with an impairment in cholesterol metabolism.

To evaluate exercise capacity, treadmill test and exercise pulmonary function test with cycle ergometer were preformed in 52 patients(pts) (M/F : 18/34, mean age : 43+/-11 yrs) with mitral stenosis before and 5~10 days after percutaneous mitral balloon valvuloplasty(PMV). Twenty four pts had atrial fibrillation. The results are as follow : 1) The mitral valve area increased from 0.9+/-0.2 to 1.8+/-0.3cm2(P<0.001). 2) The duration of exercise time on treadmill test(modified Bruce protocol) increased from 7.7+/-3.3min to 11.1+/-2.6min(P<0.001), but peak heart rate(HR) and maximum double product(MDP) did not change significantly. After exclusion of the patients with atrial fibrillation, peak HR and MDP increased from 157+/-24beats/min and 22350+/-8220mmHg beat to 165+/-19beats/min and 26290+/-5770mmHg beat respectively(P<0.05). 3) Diffusion capacity and diffusing capacity/alveolar volume at rest decreased from 95+/-25% and 112+/-24% to 87+/-22% and 100+/-18% respectively(p<0.001). 4) FVC, FEV1, FEV1/FVC, FEF25~75% and maximum voluntary ventilation increased from 77+/-12%, 79+/-16%, 104+/-10%, 69+/-25%, and 68+/-14%, to 80+/-11%, 84+/-14%. 106+/-9%, 78+/-25%, and 74+/-12%, respectively(P<0.05). But total lung capacity, residual volume and functional residual capacity did not change significantly. 5) Maximum oxygen consumption, anaerobic threshold, oxygen pulse and maximum work load during exercise increased form 53+/-14%, 34+/-8%, 6.2+/-2.1ml/min and 48+/-18 watts to 61+/-13%, 39+/-7%, 7.3+/-2.0ml/min and 58+/-20 watts respectively(P<0.0005). We conclude that oxygen transport and exercise capacity improve within 10days after PMV and the improvement results from not only hemodynamic improvement but also improvement of static pulmonary function.

PURPOSE: To evaluate the prevalence of esophageal reflux-induced symptoms after gastrectomy owing to gastric cancer and assess the relationship between esophageal reflux-induced symptoms and quality of life. MATERIALS AND METHODS: From January 2012 to May 2012, 332 patients were enrolled in this cross-sectional study. The patients had a history of curative resection for gastric cancer at least 6 months previously without recurrence, other malignancy, or ongoing chemotherapy. Esophageal reflux-induced symptoms were evaluated with the GerdQ questionnaire. The quality of life was evaluated with the European Organization for Research and Treatment QLQ-C30 and STO22 questionnaires. RESULTS: Of the 332 patients, 275 had undergone subtotal gastrectomy and 57 had undergone total gastrectomy. The number of GerdQ(+) patients was 58 (21.1%) after subtotal gastrectomy, and 7 (12.3%) after total gastrectomy (P=0.127). GerdQ(+) patients showed significantly worse scores compared to those for GerdQ(-) patients in nearly all functional and symptom QLQ-C30 scales, with the difference in the mean score of global health status/quality of life and diarrhea symptoms being higher than in the minimal important difference. Additionally, in the QLQ STO22, GerdQ(+) patients had significantly worse scores in every symptom scale. The GerdQ score was negatively correlated with the global quality of life score (r=-0.170, P=0.002). CONCLUSIONS: Esophageal reflux-induced symptoms may develop at a similar rate or more frequently after subtotal gastrectomy compared to that after total gastrectomy, and decrease quality of life in gastric cancer patients. To improve quality of life after gastrectomy, new strategies are required to prevent or reduce esophageal reflux.

One of the least frequently encountered nongliomatous intraspinal neoplasm is the teratoma. Tumors that are not dermoid or epidermoid cyst have been reported as being teratomatous or teratoid when they do not have tissue derived from all three germ layers and when they are clearly most closely related to the trigerminal teratoma. Authors described an illustrated case report of teratoid cyst of the spinal cannal, summarized the previous report cases, and discuss the classification and origin of these tumors.

In children, primary tumors of the third ventricle are uncommon. The majority of the lesion were infiltrating astrocytoma of the anterior portion of the third ventricle. Tumors within the third ventricle were benign, encapsulated, and respectable with good prognosis. But most surgerns have considered this tumors to be inoperable;accordingly shunting procedures followed by radiotherapy has been the treatment of choice. We recently experienced a case of astrocytoma which entirely filled the third ventricle with hemorrhage and reviewed the literatures.

In generalized amyloidosis, involvement of heart is not rare, but development fo severe conduction distubance in cardiac amyloidosis is a rare presentation in a clinical situation. We report the first case in Korea of cardiac amyloidosis with complete atrioventricular block, which was confirmed by endomyocardial biopsy. A 59-year-old woman was admitted due to drowsy mentality. We observed a severe atrioventricular conduction disturbance on the electrocardiogram and a marked hypertrophied ventricular wall and a granular sparkling appearance within the wall, a characteristic feature in cardiac infiltration of amyloidosis, on the echocardiography. Endomyocardial biopsy was performed and revealed extensive deposition of amorphous eosinophilic materials within the cardiac muscle cells. Polarizing illumination after Congo-red staining showed typical green birefrigence. We performed a insertion of permanent pacemaker(VVI type) for the treatment of complete atrioventricular block.

BACKGROUND AND OBJECTIVES: Clopidogrel resistance or low-responsiveness may be associated with recurrent atherothrombotic events after drug-eluting stent (DES) implantation. We prospectively evaluated the association between clopidogrel resistance assessed by the Verifynow(TM) P2Y12 assay (Accumetrics, San Diego, CA, USA) and stent thrombosis (ST) or cardiac death (CD) in patients with acute coronary syndrome (ACS) within 6 months after DES implantation. SUBJECTS AND METHODS: We enrolled 237 consecutive patients (160 males, 65.2+/-10.3 years) with ACS who received a DES implantation. The composite endpoint was defined to CD or ST by Academic Research Consortium definitions within 6 months post-implantation. Clopidogrel resistance was defined as <20% inhibition of the P2Y12 receptor. RESULTS: Baseline demographic characteristics were similar between 142 normal individuals and 95 clopidogrel resistant patients. CD occurred in one case (0.7%) in the normal group and two cases (2.13%) in the resistant group (p=0.344). There was no episode of ST in the normal group and four episodes in the resistant group (4.2%, four definite ST) (p=0.035). Univariate logistic regression revealed an adjusted odds ratio (OR) for composite end point of CD or ST of 9.646 {95% confidence interval (CI) 1.139-81.679}, and multivariate logistic regression for composite end point revealed an OR of 12.074 (95% CI 1.205-120.992). CONCLUSION: Clopidogrel low-responsiveness assessed by the Verifynow(TM) P2Y12 assay is an independent predictor of ST and composite end point of ST or CD in patients with ACS within 6 months after DES implantation.

OBJECTIVES: To correlate Frey's syndrome with subjective symptoms, Minor's starch iodine test results, and infrared thermography measurements, and to discuss the utility of thermography as a quantitative diagnostic method. METHODS: This study included 59 patients who underwent unilateral parotidectomy. A subjective clinical questionnaire and an objective Minor's starch iodine test were performed to evaluate the incidence of Frey's syndrome. Infrared thermography was performed, and the subjects were divided into seven groups according to the temperature differences between operated and unoperated sites. The thermal differences were correlated with the results from Minor's starch iodine test and the subjective symptoms questionnaire. RESULTS: Of the 59 patients, 20 patients (33.9%) reported subjective symptoms after eating; 30 patients (50.8%) tested positive for Minor's starch iodine test, 19 patients (63.3%) of which reported subjective symptoms. Of the 29 patients who were negative for the iodine test, 2 patients (6.9%) reported subjective symptoms. Thus, subjective symptoms were well correlated with Minor's starch iodine test (r=0.589, P<0.001). As the thermal differences with infrared thermography increased, the number of patients with subjective symptoms increased (chi2=22.5, P<0.001). Using infrared thermography, the mean temperature difference in the positive group for the iodine test was 0.82degrees C+/-0.26degrees C, and that in the negative group was 0.10degrees C+/-0.47degrees C. With increased thermal differences, more patients showed positivity in the iodine test (chi2=29.9, P<0.001). CONCLUSION: Subjective symptoms, Minor's starch iodine test, and infrared thermography are well correlated with one another. Quantitative thermography provides clues for the wide variation in the incidence of Frey's syndrome, and could be a useful method for diagnosing and studying Frey's syndrome.
