In order to evaluate the effects of incision location and suture method on induced astigmatism in cataract surgery, three different procedures were applied to 150 eyes which had phacoemulsification through 6 mm incision with 6 mm optic IOLs. The group 1(50 eyes) had posterior limbal incision followed by interrupted radial sutures. The group 2(50 eyes) had posterior limbal incision followed by continuous shoelace sutures. The group 3(50 eys) had scleral pocket incision at 2 - 2.5 mm apart from the surgical limbus followed by sutureless technique. The corneal astigmatism was ana lysed by algebraic and vector methods. Keratometric astigmatic changes with vector analysis on postoperative 1 day were 2.34 diopter(D), 1.41D, 0.74D in the group 1, group 2, gruop 3 respectively. There were statistically significant differences among the three groups(p<0.01). At postoperative 1 week. the keratometric astigmatic change of the group 3 was less than that of the group 1(p<0.01) and the visual acuity of the group 3 was better than that of the group 1(p<0.05). During postoperative 1 to 6 months, there was no statistically significant differences among the three groups in astigmatic changes or visual acuity. It could be concluded that scleral pocket incision with suture less technique showed significantly less astigmatism than other techniques initially, and continuous shoelace suture technique could have more stable and less astigmatism than interrupted radial suture technique.

Purpose: Contact dermatitis (CD) is a common skin disease caused by various allergens that can be identified by patch test (PT). Despite the analysis of PT outcomes in various regions of Korea, no specific investigation has targeted the Busan area. We aimed to analyze PT results using Chemotechnique in patients suspected of CD in Busan. Methods: We reviewed medical records of 273 patients who underwent PT between 2019 and 2020 at two university hospitals in Busan. PT results were interpreted according to the International Contact Dermatitis Research Group criteria. Results: Among the patients, 86.4% exhibited positive reactions to at least one allergen. Those with positive outcomes displayed a higher comorbidity rate of chronic urticaria but a lower rate of atopic dermatitis. Moreover, they reported higher positivity rates to questions about sexual life and treatment on the Dermatology Life Quality Index questionnaire. Major allergens in Busan were cobalt chloride (60.1%), nickel sulfate (52.0%), and potassium dichromate (50.9%), followed by thiomersal, balsam of Peru, and fragrance mix (17.2%, 15.4%, and 13.9%, respectively). Captan, budesonide, and colophony were more prevalent allergens in males. While the positive rate for thiomersal were higher in the younger age group, balsam of Peru allergen was higher in the older age group. Conclusion This study represents the first PT analysis conducted in Busan, revealing metal-related allergen as the most common cause of CD, with variations observed across sex and age. Further research is needed to validate these findings and elucidate the sources and pathways of allergen exposure in Busan.

BACKGROUND AND OBJECTIVES: There are relatively few studies that have evaluated the optimal timing, risk of mortality, and outcome for patients with coronary artery bypass graft surgery (CABG) performed in the setting of acute myocardial infarction (AMI). MATERIALS AND METHODS: We reviewed our 18 patients who underwent CABG within 14 days after AMI, between June 1994 and June 1997. Thirteen of the patients were male and 5 were female. Their ages ranged from 41 to 77 years (mean age, 60.6+/-10.4 years), and the amount of time betweenAMIandCABGrangedfrom4hoursto14days (meantime,7.0+/-4.7days).Therewere11 anteroseptal infarctions and 7 inferior wall infarctions. Eleven patients had transmural infarctions and 7 had subendocardial infarctions. Indications of operations were postinfarction angina, cardiogenic shock and intractable ventricular arrhythmia. Six patients required preoperative intra-aortic balloon pump (IABP) support, and 3 additional patients required IABP to be separated from cardiopulmonary bypass. An average of 3.4+/-0.5 vessels per patient were bypassed. RESULTS: The early mortality rate for these 18 patients was 5.6% and late mortality rate was 5.9%, and 2-year actuarial survival rates were 89.5%. Univariate analysis of mortality showed that an ejection fraction less than 30% was associated with risk factor (p value=0.016 ). Age, sex, time to CABG, emergency operations, locations of infarctions were not significant. CONCLUSION: Although our studies have weak points in that there was only a small number of patients and the lack of long-term results, we could conclude that early myocardial revascularization is relatively safe after AMI for those individuals with an ejection fraction greater than 30%.

PURPOSE: To evaluate the incidence,. degree, and clinical significance of non-obstructive intrahepatic bile duct di'latation encountered on follow up CT after gastrectomy for gastric carcinoma. MATERIALS AND METHODS: We retrospectively analyzed follow-up abdominal CT of 65 patients who had undergone gastrectomy with truncal vagotomy and subtotal gastrectomy for gastric carcinoma. We classified those patients who showed intrahepatic duct dilatation into non-obstructive or obstructive groups depending on the presence or absence of the lesions obstructing the duct. We also evaluated the incidence, degree and pattern, and appearance time of non-obstructive type of duct dilatation. RESULTS: Non-obstructive and obstructive biliary dilatations were present in 8 cases(12.3%) and 9 cases(13. 8%), respectively. The degree of non-obstructive group was mild in 6 cases(75%) and moderate in 2 cases (25%) who had taken cholecystectomy during the follow up period, and patterns were proportional dilatation of the central and peripheral intrahepatic ducts. It appeared on follow up CT obtained 6 to 12 months after operation in 7 cases and 3.5 months in one case. No statistical significance was noted between the type of surgery and the incidence of non-obstructive dilatation(p>0.05). CONCLUSION: Mild dilatation of the central intrahepatic ducts without evidence of mechanical biliary obstruction can be seen on follow-up CT obtained more than 6 months after gastrectomy for gastric carcinoma, and the incidence is about 12%. We think that this finding is non-obstructive and clinical evaluation is unnecessary.

We carried out the Schirmer test to measure objectively the amount of lacrimation among 51 clinically diagnosed parkinsonian patients (33 men and 18 women aged 50 to 79 years, mean 64) and 75 age-matched controls (42 men and 33 women aged 50 to 76, mean 62). Whatman No. 2 paper, prepared in precut strips 5mm by 35mm, was placed in the cul-de-sac for five minutes, after which the wetted length of the strip was studied. It was noted that the lacrimation amount decreased in patients with Parkinson's disease compared with controls: the average amount of lacrimation was 3.4 +/- 2.3mm in the former group and 8.1 +/- 6.5mm in the latter group (p < 0.01). We believe that the decrease in the amount of lacrimation is associated with emotional disturbance and autonomic dysfunction, and presume that the lacrimation may be under the control of the basal ganglia which has a connection with the superior salivatory nucleus downward and the limbic system upward.

Danon disease is characterized clinically by the triad of cardiomyopathy, myopathy and mental retardation. It was originally reported as a lysosomal glycogen storage disease with normal acid maltase by Danon. Danon disease results from mutations in lysosome associated membrane protein-2 (LAMP-2) gene. The LAMP-2 gene is located on Xq24-25. We report a case of suspected Danon disease in patient who had hypertrophic cardiomyopathy and mental retardation along with abnormal findings in electromyography.

BACKGROUND AND OBJECTIVES: The purpose of this study is to examine clinical characteristics and outcome in patients with cardiogenic shock or ongoing cardiogenic shock by acute coronary syndrome who underwent intraaortic balloon pump(IABP) support, and to identify factors predictive of in-hospital mortality. MATERIALS AND METHODS: Thirty-two consecutive patients with IABP support from 1994 to 1997 were analyzed retrospectively. RESULTS: The causes for insertion of IABP are cardiogenic shock(31%), unstable hemodynamics during angiography or angioplasty(31%), ventricular tachycardia(15%), mechanical complications(15%), and ongoing chest pain(6%). The overall survival rate was 47%. Revascularization procedures were done in 23 cases(72%) in whom inhospital survival rate was 52%. The mortality rate was significantly higher in patients with cardiogenic shock(80%) and mechanical complications(100%) including ventricular septal defect and acute mitral regurgitation, but lower with intractable ventricular tachycardia. Differences between survivors and nonsurvivors were not significant in regard to clinical characteristics, extent of coronary artery disease, time to IABP, time to coronary artery bypass graft, and clamping time, but only duration of IABP is longer in nonsurvivors. CONCLUSIONS: Emergent uses of IABP in patients with intractable ventricular tachycardia may be effective in maintaining hemodynamics before revascularization procedures, but patients with pump failure by cardiogenic shock or mechanical complications have higher mortality rates.

BACKGROUND AND OBJECTIVES: Right ventricular (RV) dysfunction is associated with a poor prognosis in patients with an acute pulmonary embolism (APE). We studied the role of electrocardiography and biomarkers for early detection and recovery of right ventricular dysfunction (RVD) in APE. SUBJECTS AND METHODS: The medical records of 48 consecutive patients diagnosed with APE using CT-angiography, at the Kangdong Sacred Heart Hospital, between January 2004 and February 2008 were reviewed retrospectively. RVD was assessed by serial echocardiography (ECG). Patients with one of the following were considered to have RVD: 1) RV dilatation (enddiastolic diameter >30 mm in the parasternal long axis view), 2) RV free wall hypokinesia, and 3) paradoxical septal systolic motion. We compared the electrocardiographic findings and the biomarkers for the early detection of RVD. RESULTS: The electrocardiographic findings showed T-wave inversion (TWI) in leads V1 to V3 with a sensitivity of 75% and a specificity of 95%, and a diagnostic accuracy of 80% for the detection of RVD, with positive and negative predictive values of 95.5% and 73.1%, respectively; these results were better than the biomarkers such as cardiac enzymes or B-type natriuretic peptide (BNP) for the early detection of RVD. TWIs persisted throughout the period of RVD, in contrast to a transient S1Q3T3 pattern detected during the acute phase only. CONCLUSION: TWIs in leads V1 to V3 had the greatest sensitivity and diagnostic accuracy for early detection of RVD, and normalization of the TWIs was associated with recovery of RVD in APE.
