We evaluated an effect of the distance between the incision line and corneal limbus on surgically induced astigmatism in sutureless cataract surgery with scleral tunnel incision. We made a 6mm scleral tunnel incision 1.0mm from the limbus (Group 1, 24 eyes) and 2.5mm from the limbus (Group 2, 30 eyes) and implanted polymethylmethacrylate (PMMA) intraocular lenses with a round optic of 6mm following phacoemulsification. We employed the Jaffe method and Cravy method of vector analysis to evaluate the change of Surgically induced astigmatism. The mean surgically induced astigmatism using Jaffe method was 1.24 D and 0.98 D one day after surgery in Group 1 and 2, respectively. The difference between them was statistically significant(p<0.01) and became insignificant(p>0.05) after postoperative one week. In the superior incision cases, the difference using Cravy method was not statistically significant for whole followup period. In the temporal incision cases, the surgically induced astigmatism was 0.39 D and 0.02 D one day after surgery in Group 1 and 2, respectively. The difference was statistically significant(p<0.05) and became statistically insignificant(p>0.05) after postoperative one week. In this study it was found that a distance of incision line from corneal limbus longer than 1 mm was not an important factor in influencing the surgically induced astigmatism one week after sutureless cataract surgery using a watertight scleral tunnel incision.

Myocarditis is defined as the myocardial inflammation caused by various infectious agents (such as virus, rickettsia , bacteria, protozoa, fungus and parasites). The clinical manifestations of myocarditis ranges from the asymptomatic state due to focal inflammation to fulminant fatal congestive heart failure secondary to diffuse myocardial involvement. Clinically, in some cases, it may simulate an acute myocardial infarction. We experienced a case of acute fulminant myocarditis that presented as acute myocardial infarction initially, and then progressed into and recovered from congestive heart failure and multiorgan failure.

BACKGROUND:We performed this study to determine the influence of the administration of pneumoperitoneum on the blood flow of the thoracoabdominal aorta during laparoscopic cholecystectomy (LC). METHODS: Ten patients for LC were enrolled in this study. Anesthesia was performed with propofol, fentanyl and rocuronium. Pneumoperitoneum was made by CO2 gas intraperitoneal instillation at an intraperitoneal pressure of 10-12 mmHg. Peak velocity of blood flow in the systolic phase (PV), mean acceleration of blood flow from the start of systole (MA) and systolic flow time corrected for heart rate (FTc), measured by esophageal doppler monitoring (EDM), and heart rate (HR) and mean brachial BP (MBP) were measured 1, 5 and 10 min after the institution of pneumoperitoneum, (T1, T5 and T10) and compared with those before the institution of pnuemoperotoneum (T0). LC was started after recording all measurements and a position change to the reverse-Trendelenberg position. RESULTS: PV, MA, FTc and HR showed no significant change throughout this study, but MBP at T5 and T10 (110.1 +/- 18.5 mmHg and 107.8 +/- 10.4 mmHg) were significantly higher than at T0 (84.9 +/- 12.9 mmHg) (P = 0.002 and 0.005 respectively). CONCLUSIONS: The administration of pneumoperitoneum neither changed nor interferenced with abdominal aortic blood flow.

Postoperative hyphema following cataract extraction surgery is not usually a serious complication and clears quickly in the most cases. Sutureless cataract surgery was reported to have less incidence of postoperative hyphema than conventional cataract surgery. We analyzed the incidence of postoperative hyphema in each group according to the depth and the length of scleral pocket incision in 500 eyes with the sutureless cataract surgery via superior incision during two years. One day after surgery, 90 cases(18.0%) had hyphema and most of them(74.4%) showed grade 1 severity. The incidence of hyphema was 23.0% in the deep incision group and only 11.9% in the superficial incision group(p<0.01). The percentage of grade 1 hyphema was 66.6% in the deep group and 92.6% in the superficial group, then severity was greatly reduced in the superficial incision group(p<0.01). The incidence of hyphema in the group of 7.0 mm in length was highest among the 6.0, 6.5, 7.0 mm groups(p<0.01), and the shorter the incision length, the milder the serverity of hyphema(p<0.01). The incidence of hyphuma was the lowest(6.2%) in the group of 6.0 mm in length and superficial incision, and it was the highest(28.5%) in the 7.0 mm in length and deep incisional group(p<0.01).

BACKGROUND: The incidence of reported nontyphoidal Salmonellosis has increased during last decade in Korea. Salmonella typhimurium and Salmonella enteritidis are two major serotypes in nontyhoidal Salmonella. To determine the nature of potential outbreak S. typhimurium infection in a community, we retrospectively evaluated clinical and epidemiologic features of S. typhimurium infections and performed pulsed-field gel electrophoresis(PFGE) to investigate a genetic relatedness of S. typhimurium isolated in Guro Hospital. METHODS: From May 1998 to April 1999, a total of 20 S. typhimurium strains were isolated from 18 patients. PFGE patterns were analyzed for 20 S. typhimurium strains Clinical and epidemiological features were evaluated from their medical records. RESULTS: Seventy two percent(13/18) were acute gastroenteritis, and 11 %(2/18) were enteric fever and 16 %(3/18) were intussusception. Seventy eight percent(14 of 18) of patients were six years old or less than. There were two major type(A, B) on PFGE analysis. Eight of 20 strains showed identical PFGE type(A1). Eleven strains were subtypes of A1. One strain showed different type(B). Similarity coefficients between A1 and its subtypes were all over 0.765 and they showed close genetic distance on dendrogrm. Antibiogram of Al eight strains were various. CONCLUSIONS: High genetic relationship among 20 S. typhimurium strains for a year in Guro area indicates that they were possibly originated from one clone and that there might be a common source of infection. More efforts should be directed toward the epidemiological investigation of the cases to detect outbreaks and prevent further spread of the infection.

IgA nephropathy is the most common form of glomerulonephritis characterized by deposit of IgA on mesangium. We experienced an elderly patient who was admitted for generalized edema, and diagnosed IgA nephropathy and early gastric cancer concomittantly. It has been reported that the incidence of nephrotic syndrome combined with malignancy increases with aging. Moreover, close relationship between IgA nephropathy and malignancy has been reported especially in the elderly patient. So, active investigations for possible malignancy are required in case of elderly patient with IgA nephropathy. In this case, we found improved proteinuria and hematuria of the patient after tumor resection during following up. This case suggest causal association between early gastric cancer and IgA nephropathy clinically.

PURPOSE: We analyzed pediatric death patients who visited Dong-Kang Hospital emergency center, in order to minimize unexpected pediatric deaths. METHODS: The authors analyzed retrospectively the medical records of 110 pediatric patients who died before and within 24 hours after admission to the emergency center of Ulsan Dong-Kang General Hospital from January 1997 to December 2002. RESULTS: We classified three categories by the cause of death, accident group(AG) 46 cases(41.8%), disease group(DG) 37 cases(33.6%), unknown cause group(UG) 27 cases(24.6%) respectively. The most common age was between two and five years of age(50.0%) in AG, under one month (40.5%) in DG, between one month and one year(51.9%) in UG respectively. The most common season was summer(37.0%) in AG, winter(51.4%) in DG, spring(37.1%) in UG respectively. The most common time on arrival was from 13:00 to 18:00(37.0%) in AG, from 7:00 to noon(43.2%) in DG, from midnight to 6:00(29.6%) and from 7:00 to noon(29.6%) in UG respectively. The most common type of accident was traffic accident(47.8%). The most common cause of death in DG was respiratory disorder(40.5%). Sudden infant death syndrome was the most common(37.1%) in unknown cause of death. CONCLUSION: Accidental injuries and severe chronic illnesses are the major cause of unexpected pediatric death. Legislation related to accidents and a parents teaching program for emergency situations are necessary to decrease cases of unexpected pediatric death.

BACKGROUNDS: As Korea has advanced into the aging society, Acute Coronary Syndrome is increased in number, especially elderly age group. The symptoms of acutecoronary syndrome in eldery were presented in atypical feature frequently. We studied the relation of the first symptom and diagnosis of acutecoronary syndrome and distribution of risk factor and coronary angiographic finding in elderly patient of korea society. METHODS: The subjects who were under went coronary angiography between 2002.5 and 2003.8 were dividedunder 65 years old group and over 65 years old group. And each group described diagnosis, risk factor, first symptom and coronary angiographic finding retrospectively. RESULTS: The diagnosis of unstable angina are more higher(46.5% vs. 26.1%, p<0.01) in the over 65 years old group and the first significant symptom of typical chest pain was more higher(57.4% vs. 47.6%, p<0.01) in the under 65 years old group and dyspnea was more higher(22.8% vs. 9.2%, p<0.01) in the over 65 years old group. The number of abnormal vessel were more higher(66.3% vs. 46.9%, p<0.01) in the over 65 years old group. CONCLUSION: Over 65 years old group compared with younger age group were prewented more frequently angina equivalent symptom than typical chest pain. And at the diagnosis of Acute Coronary Syndrome, over 65 years old group showed more severe coronary angiographic finding. Consequently, early stage of diagnostic approach and treatment need scrupulous attention in the elderly patients.

BACKGROUND: Metabolic syndrome, a concurrence of disturbed glucose and insulin metabolism, over- weight and abdominal fat distribution, dyslipidemia and hypertension, is associated with subsequent de- velopment of type 2 diabetes mellitus and cardiovascular disease, especially coronary heart disease. The aim of the study is to assess the relationship between metabolic syndrome and coronary heart disease in elderly greater than 65 years old. METHODS: Eighty two elderly patients greater than 65 years old who underwent coronary angiography were divided into two groups with metabolic syndrome or without metabolic syndrome, and assessed the association with coronary angiographic finding. The metabolic syndrome factors and cardiovascular risk factors of JNC 7 were investigated to assess the relationship with coronary heart disease in elderly. Coronary heart disease was defined as 50% or greater diameter in stenosis of coronary artery in coronary angiography. RESULTS: In elderly patients with metabolic syndrome, coronary angiographically abnormal findings(p<0.05) and multi vessel disease findings(p<0.05) were presented significantly higher than non metabolic syndrome patients. In elderly patients with 3 and more cardiovascular risk factors of JNC 7, coronary angiographically abnormal findings(p<0.05) and multi vessel disease findings(p=0.059) were presented more than the other patients. Diabetes mellitus was related significantly with coronary heart disease(p value 0.044). CONCLUSION: In elderly patients, metabolic syndrome was significantly related with coronary heart disease and diabetes mellitus had strong relationship with coronary heart disease. Metabolic syndrome and cardiovascular risk factors of JNC 7 should be further evaluated to assess the relationship with coronary heart disease in the future.

BACKGROUND: The development of androgenetic alopecia is thought to be caused by increased androgen action on the hair follicles in the genetically predisposed person. Although most reports about dehydroepiandrosterone sulfate(DHEA-S) and total testosterone in female androgenetic patients are within normal limits, there are some controversies about comparing the mean values of the patients with those of the normal control group. OBJECTIVE: The purpose of this study was to compare the mean value of plasma DHEA-S and total testosterone of the patients with those of normal controls according to their ages, and evaluate relations between hormone levels and clinical type and hyperandrogenic symptoms(HAS). METHOD: We examined 60 female patients with androgenetic alopecia for clinical types, symptoms, family histories, and other systemic diseases. The mean value of the patients were compared with those of 42 normal controls according to ages, clinical types, and HAS. RESULTS: 1. Forty two cases(70.0%) were Ludwig type I, 16 cases(26.7%) were type II, 2 cases(3.3%) were type III. 26 cases(43.3%) were between 20-29 years, 19 cases(31.7%) were between 30-39 years. 2. Common age of onset was between 20-29years(23 cases, 38.3%) and below 19 years old(21 cases, 35.0%). 3. There were 32 cases(53.3%) who showed HAS and seborrhea was the most common symptom (20 cases). 4. There were 33 cases(55.0%) who showed a family history and the father was the most common relative(19 cases). Family history of first degree relative was 31 cases(51.7%). 5. Plasma DHEA-S levels of both patients and control group were all within normal limits, and there were no significant differences in the mean values between the patients ( 1633.03+/-736.31 ng/ml) and normal controls(1764.72+/-690.94 ng/ml). There were also no difference between the patients and controls according to their ages. 6. In total testosterone, 7 out of 60 patients and 3 out of 42 normal controls were beyond the normal limit and there were no significant differences in the mean values between the patients(0.548+/-0.386 ng/ml) and normal controls(0.563+/-0.501 ng/ml). There were also no differences between the patients and controls according to their ages. 7. There was no significant difference in the mean value of DHEA-S and total testosterone among type I, types II & III, and normal controls. 8. There was no significant difference in the mean value of DHEA-S and total testosterone among patients with HAS, without HAS, and normal controls. CONCLUSION: There were no significant differences in the mean values of plasma DHEA-S and total testosterone between the patients and normal controls and no significant differences in the mean values of hormone levels according to clinical type and HAS.
