Graves disease occur in association with myasthenia gravis is rare. We report a case of Graves disease and myasthenia gravis treated by bilateral subtotal thyroidectomy and total thymectomy simultaneously. A 37 year old woman was admitted with anterior neck mass and ptosis. Various examinations were compatible with combined Graves disease and myasthenia gravis. The bilateral subtotal thyroidectomy and total thymectomy were done simultaneously. The pathologic diagnosis was Graves disease and thymic hyperplasia. The patients postoperative course was uneventful. The thyroid function of patient became euthyroid and the clinical symptoms related with myastenia gravis resolved during follow up period.

BACKGROUND AND OBJECTIVES: In acute myocardial ischemia, the conduction velocity of action potential is decreased by several electrophysiological and physical factors. The ventricular activation time(VAT) is a time duration of electrical impulse propagating from endocardium to epicardium. The goal of this study is to determine whether the reduction in conduction velocity in acute myocardial ischemia can lead a change in VAT. MATERIALS AND METHOD: Thirty patient, 18 males and 12 females, who had received percutaneous balloon coronary angioplasty(PTCA) were enrolled. The mean age was 59 years old. A twelve lead surface electrocardiogram(ECG) were obtained before, during, 1 minute, 5 minutes, and 10 minutes after the PTCA as digitized data by using Cardiolab EP 4.1 program. The magnitude of the QRS wave was amplified 3 to 4 folds and the speed was increased to 200mm/sec in order to get the VAT easily and accurately. The data was the mean of three consecutive VATs. The number of vessel treated with PTCA included left anterior descending artery(12), left circumflex artery(9), and right coronary artery(9). Among twelve chronic stable angina, sixteen unstable angina, and two acute myocardial infarction patients, twenty six had single and four had two vessel diseases. RESULTS: The significant increase in VAT during PTCA compared to that before PTCA was observed in eight of 12 leads. In addition, the significant decrease in VAT of 1, 5, and 10 minutes after PTCA compared to that during PTCA were noted. Furthermore, 10 minutes after PTCA, VAT decreased significantly compared to that before PTCA. The leads did not show a significant change of VAT depending on target vessels. The ECG of 16 patients showed changes of the ST segment during PTCA. The changes of VAT were not related to the ST segment change. CONCLUSION: The conduction delay from endocardium to epicardium in acute myocardial ischemia was presented as a prolongation of VAT in surface ECG. In addition, the conduction delay was recovered within 5 minutes after relief of ischemia. Therefore, the changes of VAT can possibly be used as one of the noninvasive parameters of myocardial ischemia.

PURPOSE: The purpose of this study was to evaluate the effects of theophylline in preterm infants with apnea on glucose homeostasis and insulin values. METHOD: In this prospective study, level of glucose and insulin were measured from peripheral blood of 8 neonates(1,450+/-114gm, 31+/-2.1week), who were admitted from April 1, 1997 to July 30, 1997 in Neonatal Intensive Care Unit of Wonkwang University Hospital, for apnea of prematurity(> 20 sec with bradycardia and/or cyanosis) were given aminophylline intravenously. Blood samples were collected at pretreatment, posttreatment 2hours, 1-2days, 3-4days, 5-7days and posttreatment 48hours, and compare to those of the 8 control neonates(1,711+/-232gm, 32+/-1.7week). RESULTS: The results were as follows: 1) Plasma glucose values were significantly higher in the treatment group than those of the control group at 1-2days(104.67+/-20.39mg/dL vs 83.43+/-15.86mg/dL) and 3-4days(111.0+/-32.39mg/dL vs 79.25+/-14.03mg/dL)(p<0.05). 2) Plasma glucose values which were increased at 1-2days(104.67+/-20.39mg/dL)and 3-4days(111.0+-32.39mg/dL), were significantly higher than pretreatment values(66.33+/-31.19mg/ dL)(p<0.02), but were not increased to the level of hyperglycemia(> 125mg/dL). 3) The mean posttreatment glucose levels drawn at 48hours after discontinuation of theophylline was significantly decreased to the values of pretreatment values compared to those of the 1-2days and 3-4days(p<0.01). 4) Insulin concentrations were also increased insignificantly when blood glucose were increased in the treatment group compared with control group. CONCLUSION: In conclusion, intravenous administration of theophylline produces hyperglycemia significantly, including an increase in a serum insulin. But, clinically significant hyperglycemia(> 125mg/dL) was not noted. So, plasma glucose may not need to be monitored in preterm apneic infants receiving theophylline. But, further studies are need to elucidate the effect of theophylline considering the serum toxic level of theophylline.

BACKGROUND : The recent studies shows that Helicobacter pylori (H. pylori) related chronic gastritis leads to dysplasia, intestinal metaplasia and gastric cancer. The aim of this study was to determine the association between precancerous lesion of stomach (dysplasia, intestinal metaplasia) and H.pylori infection in the elderly. METHODS : 469 patients were enrolled this study, Patients with intestinal metaplasia or dysplasia (case, n=148) were compared with controls (without intestinal metaplasia and dysplasia, n=321) about H. pylori positive rates H. pylori positivity was confirmed by histologic determination of endoscopic biopsy specimens. Results : 1) Among study populations H. pylori positive rates were 51.8% (55.8% in male, 40.7% in female). It was significantly higher in male (p=0.001). 2) There were no significant differences in sex distribution between cases and controls, but in old age, the cases were more frequent than in young age (p<0.001). 3) Age distribution of H. pylori positive rates were not significant between cases and controls. 47.5% in intestinal metaplasia, 43.4% in dysplasia, 21.3% in dysplasia+intestinal metaplasia were H. pylori positive. H. pylori positive rates were more higher in controls than cases, followed by in decreasing order by the intestinal metaplasia group, the dysplasia group, and those having both (p=0.003). 4) Age and sex adjusted H. pylori positive rates were more higher in controls (42.7%) than in cases (25.0%)(p<0.009). CONCLUSION : The prevalence of intestinal metaplasia and dysplasia was age dependent. But we couldn't explain the carcinogenic effect of H. pylori, because H. pylori positive rates were lower in cases than in controls

BACKGROUND: Recent evidences suggest that anesthetic action within the spinal cord is important in suppressing somatic responses to painful stimuli. Intrathecal endothelin-1 (ET-1) is known to have antinociceptive effect. The purpose of this experiment was to determine whether intrathecal ET-1 may influence the minimum alveolar concentration (MAC) of isoflurane in rats and access the role of the spinal cord as the sites of anesthetic action in blocking somatic responsiveness. METHODS: In Sprague-Dawley rats fitted with an indwelling intrathecal catheter, we determined the MAC of isoflurane using a tail-clamp technique as a painful stimulus, combined with end-tidal anesthetic sampling. In experiment 1, the control MAC was determined and changes of control MAC were observed after intrathecal ET-1 (4x10-2 nmol, 4x10-3 nmol) administration. In experiment 2, we observed the effects of L or N type Ca++ channel blocker such as verapamil (50 g) or W-conotoxin (0.5 g) on the MAC after measurement of the control MAC. In experiment 3, after measurement of the control MAC, ET-1 (10-2 nmol) was administered intrathecally and the MAC was determined again. Next, intrathecal verapamil (50 g) or W-conotoxin (0.5 g) was injected. After that, the MAC was determined again. RESULTS: In experiment 1, ET-1 decreased the MAC of isoflurane and its effect was sustained over 2 hours. In experiment 2, the MAC, determined following administration of verapamil or W-conotoxin, was not different from that of the control. In experiment 3, the MAC was decreased after ET-1 administration and then increased following injection of verapamil or W-conotoxin. CONCLUSIONS: These results suggested that ET-1, in relation to calcium, might play an important role in determining the MAC of isoflurane in the spinal cord.
