The purpose of our study is to evaluate the visual, refractive and IOP results following combined small incision phacoemulsification, foldable lens implantation, and fornix based trabeculectomy with Mitomycin-C. Seventy-six eyes of 64 patients with cataract and glaucoma had undergone the combined procedure. Minimal follow-up period was 6 months(mean 12.8+/-4.8 months). All the eyes that were free of preexisting macular disease and endstage glaucomatous optic nerve damage demonstated significant improvement in visual acuity. Postoperative astigmatisn was negligible(-0.41diopters). The average IOP reduction was 7.7mmHg. Functioning filtrating bleb persisted in 76.3% of the eyes. Complications with this method were not significant compared with other studies reporting the combined procedure. The small incison phacotrabeculectomy with mitomycin-C technique that we describe appears to be effective in early restoration of visual acuity and reduction of IOP without significant complications.

The anterior cruciate ligament has been considered one of the basic stabilizers in the knee as a very complex in its function. A large number of treatment regimens and philosophies showed controversies in its treatment. And we have experienced recurrence of the instability after operation of the injured ligament. So, the authors devised a new operative technique for the loose anterior cruciate ligament, that is, distal davancement of the loose anterior cruciate ligament with a bone-block as a biomechanical fixation. We have performed 11 cases of the anterior cruciate ligament using distal advancement method. The results were as follows; 1. Eleven cases (92%) showed good results by the rating system of Cincinnati sports-medicine and Orthopaedic Center. 2. The distal advancement of the anterior cruciate ligament is technically simple and biomechanically reasonable, but further investigation is necessary to answer the question regarding the long term results.

Authors performed Ilizarov treatment for 9 cases of severse knee flexion contracture. The causes of knee flexion contracture were 2 cases of rheumatoid arthritis, 2 cases of malunion of tibia and femur, 2 cases of infection sequelae, and 3 cases of hemophilic arthritis. The preoperative flexion contracture was av. 65.6 degrees(40-90 degrees). We started the correction at postoperative av. 3.88th day(2-12th day) after postoperative pain was controlled. After the deformity was corrected, the frame was left in place for av. 16.6 days(6-42 days). But in 2 cases of malunion of tibia and femur and 1 case of infection sequela, angular deformity and leg length discrepancy were managed after the correction of knee flexion contracture. The postcorrection flexion contracture was av. 2.6 degrees(0-10 degrees). The correction rate was av. 1.71 degrees/day(0.57-4.16 degrees/day) and the duration for correction was av. 51.1 days(12-85 days). After the follow-up period of av. 7.6 months from removal of Ilizarov, flexion contracture was av. 10.0 degrees(0-25 degrees). We conclude that the severe flexion contracture of the knee can be treated successfully with the Ilizarov correction. Limb shortening and neurovascular injuries can be avoided or minimized with the Ilizarov correction for flexion contracture of the knee as apposed to the other method. The recurrence of the flexion contracture of the knee may be prevented with the sufficient maintenance period.

Behcet's disease (BD) is a systemic vasculitis involving diverse sizes of arteries and veins. We performed this study to evaluate the vascular changes by assessment of the arterial stiffness and intima-media thickness (IMT) of carotid artery in Korean patients with BD. Forty-one patients with BD and age-, and sex-matched 53 healthy subjects were recruited in this study. Carotid arterial stiffness and IMT were assessed by using high-resolution B-mode ultrasonography. Arterial stiffness parameters such as carotid arterial distensibility coefficient, stiffness index, and incremental elastic modulus (E(inc)) were significantly increased in BD patients compared with those in healthy subjects, but not in IMT. Positive relationship was noted between age and IMT, whereas age of onset was significantly associated with arterial stiffness in BD. This finding suggests impaired endothelial function before visible structural changes of arterial wall in BD. Age and age of onset may be an independent risk factor for carotid IMT and arterial stiffness, respectively. Further studies in more large populations are required to confirm our results.

BACKGROUND: Ventrlcular tachyarrhythmias are major cause of sudden cardiac death in patients after myocardial infarction and their accurate detection seems to be important in prevention of sudden cardiac death. Clinical findings, treasmill test, holter monitoring and coronary angiography have been used to search for high risk group in sudden cardiac death. Recently electrographysiologic stimulation has been to this, but it is not practical, because of high cost and invasiveness. Signal averaged electrocardiogram(SAECG) may be helpful in prediction of high risk group in sudden cardiac death. So we try to know the values of SAECG in Korean patients without heart disease. RESULTS: 1) The mean value and standard deviation of Time domain analysis is as follows ; fQRS : 106.8+/-12.3ms, RMS : 36.2+/-21.5(micro)V, LAS : 27.2+/-8.1ms. 2) The mean value and standard deviation of Spectral turbulence analysis is a follows ; LSCR : 58.6+/-3.9, ISCM : 95.2+/-0.8, ISCSD : 71.8+/-15.7, SE : 6.9+/-1.8. CONCLUSION: There was no significant difference between male and female. Time domain analysis shows significant differences among each hour but spectral turbulence analysis did not. Spectral turbulence analysis shows high specificity.

BACKGROUND: The interpretation of electrocardiographic change in treadmill exercise test is difficult when the test is performed in patients with abnormal resting electrocardiography. In patients with primary nagative T wave, normalization of primary negative T wave(pseudonormalization)is not uncommon finding during treadmill exercise test. The mechanism of pseudonormalization is uncertain and the interpretation is difficult. Thus this study was performed to evaluate the diagnostic significance of pseudonormalization during treadmill exercise test. METHODS: 200 cases who showed primary negative T wave at rest were included in this study. The results were classified as positive, borderline positive, borderline negative, negative, non-diagnostic and pseudonormalization. RESULTS: Pseudonormalization during treadmill exercise test was oberved in 78(39%) of the 200 cases who had primary negative T wave at rest. Coronary angiography and left ventriculography were performed in 13(mean age 56+/-7 year, male vs. female 1:2.25) of 78 cases who showed pseudonormalization during exercise. They had no history of acute myocardial infarction and no abnormalities such as abnormal Q wave, left ventricular hypertrophy,bundle branch block,right ventricular hypertrophy and QRS widening above 0.1ms in resting electrocardiography. There were significant stenosis in only 3 cases; 2 cases in left anterior descending coronary artery and 1 case in right coronary artery. CONCLUSION: In treadmill exercise tests, pseudonormalization appears as non-specific finding for the diagnosis of ischemic heart disease becuase it is observed in either patients with or without coronary artery stenosis.

The effects of resin on the respiratory health have been investigated in 309 workers from four iron and steel foundries and the results compared with those from 122 workers who were not significantly exposed to resin gas and silica dust at the same industries. Phenol-formaldehyde resin was used in the core making and molding processes and workers were exposed to their decomposition products as well as to silica dist containing particulates The subjects were grouped according to formaldehyde, dust and other gas exposures, and smoking habits were considered also in the analysis. Standardized respiratory symptom questionnaire was administered by trained interviewers. Chest radiograph, pulmonary function tests, and methacholine challenge tests were done. Environmental measurements at the breathing zone were carried out to determine levels of formaldehyde, respirable dust and total dust. Foundry workers had a higher prevalence of symptoms of chronic bronchitis with chronic phlegm and chronic cough when exposed to dust. Exposure to gas was significantly associated with lowered FEV1 and obstructive pulmonary function changes. Exposure to formaldehyde and phenol gas was associated with wheezing symptom among workers, but FEV1 changes after methacholine challenge were not significantly different among different exposure groups. When asthma was defined as the presence of bronchial hyperreactivity with more than 20% decrease in FEV1 after methacholine challenge, 17 workers out of 222 tested had asthma. Fewer asthmatic workers were found among groups exposed to for maldehyde, gas and dust, which indicates a healthy worker effects in a cross-sectional study. The concentration of formaldehyde gas ranged from 0.24 to 0.43 ppm among studied foundries. The authors conclude that fornaldehyde and phenol gas from combust resin is probably the cause of asthmatic symptoms and also a selection force of those with higher bronchial reactivity away from exposures.

BACKGROUND AND OBJECTIVES: Psychogenic dizziness has not been studied extensively in Korea while it is seen frequently. We investigated the prevalence of psychiatric diagnosis and the results of vestibular function testings in patients with the diagnosis of psychogenic dizziness at a Korean tertiary university hospital. MATERIALS AND METHODS: The study was conducted on 38 patients with the diagnosis of psychogenic dizziness. They all received vestibular function testings (ENG, rotating chair test and posturography). Patients with central or vestibular organic disease were excluded from this study. RESULTS: Somatoform disorder was the most common psychiatric disorder causing psychogenic vertigo(47.4%) in this study. Anxiety disorder(21.1%) and depression(21.1%) were the next common causes. The vestibular function testings were abnormal in 19 patients(50.0%). The electronystagmography in 11, rotating chair test in 6, and posturography in 14 patients were abnormal. CONCLUSIONS: Somatoform disorder was the most common psychiatric disorder and vestibular function tests were abnormal in 50% of psychogenic dizziness patients. It implies that the patients with psychogenic dizziness have functional abnormalities in vestibular system.
