Purpose: Divergence insufficiency is characterized by esotropia at far distance with symptomatic diplopia, minimal or no deviation at near distance, and full ocular duction and version. We analyzed the results of bilateral lateral rectus (BLR) tucking in patients with divergence insufficiency. Methods: Surgery was performed on patients with persistent distance diplopia with esotropia for at least 6 months after diplopia onset. The surgical results were evaluated after BLR tucking based on the maximum angle of deviation at distance among all the angles of deviation measured repeatedly, including the results of the prism adaptation test (PAT). Results: 24 patients were included. The average follow-up period was 14 months (1-48 months). The maximum deviations measured by alternate prism and cover test before surgery were 24.79 ± 8.15 prism diopter (PD) at far distance and 15.45 ± 9.30 PD at near distance. The PAT revealed that, the far distance deviation increased to 28.50 ± 7.77 PD and that at near distance to 25.88 ± 8.07 PD, but the difference between the two values fell to less than 3 PD on average. In 14 patients (58%), followed-up for up to 1 year, we noted no recurrence of diplopia or esotropia, or near distance overcorrection, with the exception of one patient who developed diplopia recurrence at far distance. Conclusions BLR tucking guided by the maximum distance deviation of the 1 hour PAT affords stable results in patients with divergence insufficiency without overcorrection at near distance or undercorrection at far distance.

BACKGROUND: Recently, the apartment complex is rapidly increasing as a new type of housing in a large city. So the purpose of the this survey is to research the experience rate of young children's allergic disease in an area of the apartment complex of a large city and to help the family medical doctor to diagnose and treat the young patients. METHODS: The experience rate of atopic dermatitis, bronchial asthma, allergic rhinitis, allergic conjunctivitis, food allergy was surveyed on June 1999 at an elementary school in a large apartment complex in Kwang ju. The survey group were 832 students attending elementary school from the second to sixth grade. Also this survey was used to elicit information about the relationship between allergic disease and factors such as age, sex, birth history, family history, and home environment. For analysis of our finding, we have been used chi square test. RESULTS: The survey shows that the experience rate of allergic disease is 40.4%. The experience rate of allergic disease was not related with sex, but the more ages the less experience rate. Allergic disease was not related with birth weight, gestational age, feeding method, use of carpet, breeding of pet, smoker in home, and the previous housing type. But experience rate of allergic disease was increased with positive family history. CONCLUSION: General facts of allergic disease in elementary school children had no differentiation between large city and the other region. The experience rate of allergic disease is 40.4%.

Bronchogenic cysts (BCs) are relatively common congenital anomalies in the mediastinum. Most of the patients with BC can be managed both safely and effectively by minimally invasive methods. Selected patients with a BC in a favorable location can have the cyst partially or completely excised by mediastinoscopic techniques. Herein we report on a case of a left lower paratracheal bronchogenic cyst that was completely resected by a video-assisted mediastinoscopic technique, and we discuss the technical aspects of this procedure.

BACKGROUND: Ventricular remodeling after myocardial infarction increase mortality and morbidity. Two-dimensional echocardiography in acute myocardial infarction provides a useful diagnostic tool for evaluation of ventricular remodeling. The aims of this study were to verify whether follow-up two-dimensional echocardiography could detect ventricular enlargement after acute myocardial infarction and to find early echocardiographic predictors and clinical charateristics of ventricular enlargement. METHODS: Two-dimensional echocardiography was done prospectively at 2 week, 3 month, and 6 month after the first Q-wave acute myocardial infarction in 18 patients. The control group was 11 patients of a normal chest roentgenogram and echocardiogram who were studied for chest pain or arrhythmia. The patients were divided by the mean value of the control group left ventricular end-diastolic volume index(LVEDVI) 56.8ml/m2. The group A was more than 60ml/m2(the control group LVEDVI 56.8ml/m2) and the group B was less than 60ml/m2 of LVEDVI at 2 week post myocardial infarction. The left vantricular volume was measured by the modified disk method at the apical four chamber view. The wall motion abnormality of left ventricle was examined by the recommendation of the American Society of Echcardiography. RESULTS: The left vntricular end-diastolic volume and the left ventricular end-systolic volume were enlarged after 3 month of acute myocardial infarction in the group A compare with those of the control group. There was no ventricular enlargement during 6 month after myocardial infarction in the group B. The frequency of ventricular enlargement was increased in anterior myocardial infarction. There was no difference in left ventricular ejection fraction at 2 week post myocardial infarction between the group A(51.4+/-15.7%) and the group B(50.8+/-10.3%). The wall motion score index more than 1.5 at 2 week post myocardial infarction means the enlarged LVEDVI more than 60ml/m2 and the group of ventricular enlargement. CONCLUSION: The left ventricular enlargement could be diagnosed by the follow-up two-dimensional echocardiography in acute myocardial infarction. The echocardiographic early predictors of ventricular enlagement were the left ventricular end-diastolic volume greater than 60ml/m2 and increased wall motion score index more than 1.5 at 2 week post myocardial infarstion. The anterior myocardial infarction was the electrocardiographic predictor of ventricular dilatation. Therefore these early predictors could identify the patients of ventricular enlargement and these patients could be a candidate of follow-up echocardiography and of a specific treatment for limiting ventricular remodeling.

OBJECTIVE: We report the correlation between known risk factors for cerebrovascular disease and formation of multiple intracranial aneurysms. METHODS: We reviewed the medical records and outcomes of 524 patients who had undergone aneurysmal operation at our hospital between January 1996 and May 2001. Of 524 patients who had undergone operations with intracranial aneurysm, 130 patients had multiple intracranial aneurysms. The authors examined the correlations between the risk factors(patient age, sex, menopausal state of female patients, hypertension, cigarette smoking) and the presence of multiple intracranial aneurysms by using chi-square test retrospectively. RESULTS: The male to female ratio was about 1 : 2.05(male : female=129 : 265) for patients with single intracranial aneurysm, and male to female was about 1 : 3.06(male : female=32 : 98) for patients with multiple intracranial aneurysms. Among 256 female patients with single intracranial aneurysm, 182 patients(68.9%) were postmenopausal, and, among 98 female patients with multiple intracranial aneurysms, 81 patients(82.6%) were postmenopausal. The mean age of the patients with single intracranial aneurysm was 54 years, and, with multiple intracranial aneurysms, the mean age was 57.8 years. The presence of hypertension was found in 149 patients(37.8%) with single intracranial aneurysm, and, in 55 patinets (42.3%) with multiple intracranial aneurysms. Cigarette smoking was found in 116 patients(29.4%) with single intracranial aneurysm and 47 patients(36.1%) with multiple intracranial aneurysms. CONCLUSION: There is a significant correlation between menopausal state of female patients and presence of multiple intracranial aneurysms. However, gender, hypertension and smoking are not related to multiple intracranial aneurysms.

The purpose of this study was to determine the effect of reperfusion about infarct size and infarct expansion by different duration of ischemic time. Temporary coronary ligation was performed in rats for 30min, 60min, 90min and 120min, followed by reflow. Rats with permanent ligation were used for comparison. After 7 days, transverse histologic heart sections were prepared for structual analysis. The results were as follows ; 1) Reperfusion after 30 min ischemic time 1.Infarct size of reperfusion (method 1 ; 16.5+/-8.3%, method 2 ; 20.9+/-8.0%) was smaller than that of permanent ligation (method 1 ; 29.8+/-8.9%, method 2 ; 33.5+/-12.1%)(p<0.01, p<0.05). 2. Expansion index of reperfusion (46.9+/-19.6) was smaller than that of permanent ligation (88.0+/-34.9)(p<0.01). 3. The infarct thickness of reperfusion (1.59+/-0.40mm) was larger than that of permanent ligation (1.10+/-0.21mm)(p<0.01). 4.The viable left ventricular tissue area of reperfusion (28.8+/-2.90mm2) was larger than that of permanent ligation (24.2+/-3.10mm2)(p<0.01). 2) Reperfusion after 60 min ischemic time 1. There was no difference in infarct size between reperfusion and permanent ligation. 2. Expansion ratio (27.2+/-5.9%) and expansion index (51.8+/-24.6) of reperfusion were smaller than those of peremanent ligation (35.7+/-7.4%, 88.0+/-34.9)(p<0.05, P<0.05). 3. The infarct thickness of reperfusion (1.48+/-0.32mm) was larger than that of permanent ligation (1.10+/-0.21mm)(p<0.01). 3) Reperfusion after 90~120 min ischemic time reduced neither infarct size nor infarct expansion. The results of this study in the rat preparation suggest a beneficial effect of reperfusion even in late on infarct expansion independent of myocardial salvage.

BACKGROUND: The estimation of coronary flow velocity(CFV) is essential for assessing the impaired coronary flow reserve in patients whith angina pectoris and normal coronary arteries. But, intracoronary blood flow velocity measurement remains invasive,requiring cardiac catheterization and can not be repeated without risk during serial follow-up study. Transesophageal Doppler echocardiography(TEE) is a new noninvasive method of assessing CFV in the proximal portion of left anterior descending coronary artery. This study was performed to clarify the value of TEE in evaluating CFV, to compare the coronary flow patterns among various cardiac diseases, to estimate the coronary flow dynamics according to change of blood pressure, and to evaluate the parameters influencing CFV. METHODS: We studied 95 subjects, 51 men and 44 women, mean age 46. Normotensive subjects were 29, hypertensive patients 41, aortic stenosis 5, aortic regurgitation 4, mitral stenosis 8, and others 8. After transthoracic echocardiography(H-P Sonos 1000,2.5 MHz), transesophageal echocardiography was performed using a 5-Hz(omniplane)transesophageal probe connected to a H-P Sonos 1000 to assess CFV in the proximal portion of left anterior descending coronary artery. Doppler evaluation of left anterior descending coronary blood flow velocity was obtained in restiong conditions and after sublingual administraion of nitroglycerim(0.6mg), Blook pressure and heart rate were monitored thoughout the entire procedure. RESULTS: 1) The detection rate of CFV by TEE was 89.5%. 2) The morphology of CFV in proximal left anterior descending coronary artery was biphasic(greater diastolic and smaller systolic). 3) The baseline CFV in hypertensive patients was greater than in normotensive subjects(p<0.05) but there was no difference between two groups in diastolic/systolic CFV ratio. 4) The diastolic CFV and diastolic/systolic CFV ratio in patients with aortic stenosis were greater than in normotensive subjects(p<0.05). 5) The CFV was significantly decreased after administration of nitroglycerin(p<0.05) and the decrement of CFV correlated closely with the decrement of systolic(r=0.65, p<0.05) and diastolic blood pressure(r=0.57, p<0.05). 6) Major parameters influencing CFV were systolic blood pressure and heart rate. CONCLUSION: The CFV is influenced by various parameters and the TEE may be a useful, noninvasive tool to investigate the coronary flow dynamics.

BACKGROUND: The interest of patients with chest pain and normal coronary arteries has been increased since 1960. From the year 1973, the syndrome representing these characteristics has been classified as syndrome X. Treadmill test and exercise TI-201 SPECT are important in the diagnosis of syndrome X. This study was designed to evaluate the clinical value of exercise TI-201 SPECT and the difference of clinical characteristics between exercise TI-201 SPECT positive(Group A) and negative (Group B) in patients with chest pain and normal coronary angiogram. METHODS: Twenty seven patients with chest pain and normal coronary angiogram underwent echocardiogram and exercise TI-201 SPECT. Patients received 2 mCi of thallium intravenously during exercise, redistribution images were performed 4 hour later and second dose of 1 mCi of thallium was injected at rest immediately thereafter. These three sets of image(stress, redistribution and reinjection) were analyzed. RESULTS: 1) 12 of 16 patients in Group A, none of 11 patients were positive on exercise treadmill test(p<0.005). 2) The incidence of systemic hypertension in Group A was significant greater than Group B(p<0.05). 3) The left ventricular end diastolic pressure was significantly higher in Group A than in Group B (p<0.05). CONCLUSION: The exercise TI-201 SPECT is a useful method to evaluate the patients with chest pain and normal coronary angiogram and the reversible perfusion defects on the exercise TI-201 SPECT might be related to systemic hypertension and elevated left ventricular end diastolic pressure.

BACKGROUND: The autonomic nervous system plays a critical role in triggering ventricular arrhyhmia and sudden death early after acute myocardial infarction. This study was designed to determine whether or not vagal and sympathetic responses are impaired after myocardial infarction and to evaluate the utility of physiologic stress tests for assessing autonomic dysfunction after myocardial infarction. METHODS: 8 male patients with acute myocardial infarction(Group A) and old myocardial infarction(Group B) were studied with 8 control subjects of coinciding age and sex. 5 physiologic stress tests(deep breathing, sudden standing, Valsalva maneuver, ice bag application on the face, 70degrees headd-up tilt test) were performed. RESULTS: 1) Variation in heart rate during deep breathing, Standing-up, Valsalva maneuver, and ice bag application on the face was less in Group A than in Group B or Group C. 2) There was no significant difference in variation of heart rate between Group B and Group C. 3) Variation in heart rate caused by 70degrees tilt was not significantly different among the three groups. CONCLUSION: Early after myocardial infarction, parasympathetic responses were significantly impaired, whereas sympathetic responses remained intact. Heart rate variability using physiologic stress test may be provide a means of detecting autonomic dysfunction after acute myocardial infarction.
