We evaluated the need for prophylactic postoperative oral antibiotic medication in extraction of asymptomatic impacted mandibular third molars. All patient didn't show sign of pain, inflammation, swelling and trismus at the time of extraction. In the experimental group, oral antibiotic medication(Amoxicillin) was carried out for 5 days postoperatively. In the control group, the patients received no antibiotic medication. All groups didn't use antibiotic irrigation solution. Rule of group composition randomized. The surgical technique was the same in all cases. Parameters that were evaluated were infection, pain, facial swelling, trismus. We could not find any significant difference between the experimental and control groups.(P<0.05) The results of our study show that post operative oral prophylactic antibiotic medication after the extraction of impacted mandibular third molars does not contribute to less infection, pain, facial swelling and increased mouth opening after surgery. Therefore we suggest that prophylactic postoperative oral antibiotic medication is not needed in extraction of asymptomatic impacted mandibular third molars.

Maternal diabetes is known to have teratogenic effects which increase the risk for congenital anomalies, such as caudal dysplasia, cardiac defects, hydronephrosis, and small left colon syndrome. Infants of diabetic mothers have a 10-fold higher frequency of anomalies in the central nervous system and a 5-fold higher frequency of congenital heart defects. However, jejunal atresia combined with multiple anomalies of the face, ears, and hands has rarely been reported. Herein we report a neonate born to a diabetic mother, who had hemifacial microsomia, displacement of the lacrimal ducts, polydactyly of the right hand, microtia of the right ear and proximal jejunal atresia presenting as bile regurgitation on the 1st day of life.

To investigate the properties of ryanodine binding sites of the bird skeletal SR vesicles, SDS PAGE, purification of RyR, and (3H)ryanodine binding study were carried out in the SR vesicles prepared from the chicken pectoral muscle. The chicken SR vesicles have two high molecular weight (HMW) protein bands as in eel SR vesicles on SDS PAGE. The HMW bands on SDS PAGE were found in the (3H) ryanodine peak fraction (Fr3-5) obtained from the purification step of the ryanodine receptor protein. Bmax and KD of the chicken (3H)ryanodine binding sites were 12.52 pmol/mg protein and 14.53 nM, respectively. Specific (3H)ryanodine binding was almost maximal at 50~100 micrometer Ca2+, but was not increased by 5 mM AMP and not inhibited by high Ca2+. Binding was significantly inhibited by 20~100 micrometer ruthenium red and 1 mM tetracaine, but slightly inhibited by Mg2+. From the above results, it is suggested that chicken SR vesicles have the ryanodine binding sites to which the binding of ryanodine is almost maximal at 50~10 micrometer Ca2+, is significantly inhibited by ruthenium red and tetracaine, slightly inhibited by Mg2+, but not affected by AMP and not inhibited by high Ca2+.

BACKGROUND AND OBJECTIVES: Acute heart failure (AHF) is associated with a poor prognosis and it requires repeated hospitalizations. However, there are few studies on the characteristics, treatment and prognostic factors of AHF. The aims of this study were to describe the clinical characteristics, management and outcomes of the patients hospitalized for AHF in Korea. SUBJECTS AND METHODS: We analyzed the clinical data of 3,200 hospitalization episodes that were recorded between June 2004 and April 2009 from the Korean Heart Failure (KorHF) Registry database. The mean age was 67.6+/-14.3 years and 50% of the patients were female. RESULTS: Twenty-nine point six percent (29.6%) of the patients had a history of previous HF and 52.3% of the patients had ischemic heart disease. Left ventricular ejection fraction (LVEF) was reported for 89% of the patients. The mean LVEF was 38.5+/-15.7% and 26.1% of the patients had preserved systolic function (LVEF > or =50%), which was more prevalent in the females (34.0% vs. 18.4%, respectively, p<0.001). At discharge, 58.6% of the patients received beta-blockers (BB), 53.7% received either angiotensin converting enzyme-inhibitors or angiotensin receptor blockers (ACEi/ARB), and 58.4% received both BB and ACEi/ARB. The 1-, 2-, 3- and 4-year mortality rates were 15%, 21%, 26% and 30%, respectively. Multivariate analysis revealed that advanced age {hazard ratio: 1.023 (95% confidence interval: 1.004-1.042); p=0.020}, a previous history of heart failure {1.735 (1.150-2.618); p=0.009}, anemia {1.973 (1.271-3.063); p=0.002}, hyponatremia {1.861 (1.184-2.926); p=0.007}, a high level of serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) {3.152 (1.450-6.849); p=0.004} and the use of BB at discharge {0.599 (0.360-0.997); p=0.490} were significantly associated with total death. CONCLUSION: We present here the characteristics and prognosis of an unselected population of AHF patients in Korea. The long-term mortality rate was comparable to that reported in other countries. The independent clinical risk factors included age, a previous history of heart failure, anemia, hyponatremia, a high NT-proBNP level and taking BB at discharge.

BACKGROUND AND OBJECTIVES: Metabolic syndrome (MetS) increases the risk of heart failure (HF). The purpose of this study was to identify the prevalence of MetS in patients with HF and determine the syndrome's association with HF in clinical and laboratory parameters. SUBJECTS AND METHODS: A total of 3200 HF patients (67.6+/-14.5 years) enrolled in a nationwide prospective Korea HF Registry between Jan. 2005 and Oct. 2009. Patients were divided into two groups according to the presence or absence of MetS at admission: group I (presence, n=1141) and group II (absence, n=2059). RESULTS: The prevalence of MetS was 35.7% across all subjects and was higher in females (56.0%). The levels of white blood cells, platelets, creatinine, glucose, and cholesterol were significantly higher in group I than in group II. Left ventricular dimension and volume was smaller and ejection fraction was higher in group I than in group II. An ischemic cause of HF was more frequent in group I. The rates of valvular and idiopathic cause were lower in group I than in group II. The rate of mortality was lower in group I than in group II (4.9% vs. 8.3%, p<0.001). CONCLUSION: Despite the increased cardiovascular risks in MetS, MetS was found to be associated with decreased mortality in HF.

BACKGROUND AND OBJECTIVES: Congestive heart failure is one of the most frequent problems in cardiovascular patients. The objectives of this study were to evaluate the demographic and clinical characteristics and prognostic factors of patients hospitalized with congestive heart failure in Korea. SUBJECTS AND METHODS: Nine university hospitals were involved, and gathered prospective clinical data on patients with heart failure. One thousand eight hundred and sixty four patients, admitted between Jan.1 1998 and Aug. 31 2003, were enrolled, and data from 1,759 patients were analyzed. RESULTS: The cumulative survival rates at 6 month, and 1 and 2 years were 90.8, 80.1 and 76.4%, respectively. Ischemic heart disease was the most frequent underlying disease (32.3%). Diabetes mellitus (OR: 1.682, 95%CI: 1.234-2.389, p=0.005), a previous history of myocardial infarction (OR: 2.521, 95%CI: 1.742-4.258, p<0.0001) and cerebrovascular accidents (OR: 2.020, 95%CI: 1.166-3.101, p=0.001) were the worst prognostic factors. CONCLUSION: Ischemic heart disease was the major cause of heart failure. The two year survival rate of patients with congestive heart failure was 76.4%. The factors relating to a poor prognosis were diabetes, a previous history of myocardial infarction and cerebrovascular accidents.

Despite advances in the characterization of anaplastic large cell lymphoma (ALCL), little data is available on Asian patients. We report here upon single Korean institution's experience regarding the clinical characteristics and outcomes of ALCL. We performed a retrospective study of 32 adults with ALCL. Most of the patients received anthracycline-based chemotherapy. Ann Arbor stage III-IV, B symptoms, high-intermediate/ high International Prognostic Index (IPI), and extranodal disease at diagnosis were present in 56%, 44%, 41%, and 63%, respectively. Compared with Western studies, the male/female ratio (4.3) was markedly higher and skin (9%) and bone involvement (9%) were less frequent. The staining results for anaplastic lymphoma kinase were positive in 6 (33%) of 18 cases available. The complete response (CR) rate was 62% (95% CI, 44-80%). With a median follow-up of 51.0 months, 5 yr overall survival was 40+/-11%. The 3 yr relapse-free survival for the 18 patients who achieved CR was 74+/-12%. Age, performance status, lactate dehydrogenase, extranodal disease sites number, and IPI were correlated with treatment response and survival. Our data suggest that Korean ALCL patients appear to have a higher male/female ratio, less frequent skin/bone involvement, and lower CR rate compared with those of Western studies.

PURPOSE: The aim of this study was to assess the involvement of several organs patients with Marfan syndrome in Korea. Also the clinical features in childhood patients with Marfan syndrome were assessed. METHODS: Thirty-eight cases of Marfan syndrome were enrolled in this study. Clinical evaluations of the musculoskeletal, cardiovascular and occular system were performed in all cases. RESULTS: The musculoskeletal system was involved in 32 cases (84.2%) and occular system in 24 cases (63.1%). Cardiovascular abnormalities were found in 19 cases (50.0%) at initial evaluation. Family history was involved in 21 cases (55.2%). Ectopia lentis was found in 17 cases (70.8%). Severe myopia and iris abnormalities were also present in 14 cases (58.2%). The ascending aorta was dilated in 13 cases (34.2%). Emergency operation was performed in 3 cases (7.9%) because of a dissecting aorta. Mitral regurgitation and prolapse were found in 29 cases (76.4%) and other valve insufficiency was accompainied in 5 cases (13.1%). Of the 38 cases, 29 patients (79.3%) were less than 15 years of age and their major manifestations were occular problems in 23 cases (79.3%), and family history in 17 cases (58.6%). In one infant, severe heart failure was the predominant clinical feature. CONCLUSION: The clinical features of Korean patients with Marfan syndrome were summarized in this report. Heart failure was the main manifestaton in infantile Marfan syndrome. Early treatment with beta-blocker and valvular replacement can prevent fatality, i.e. aortic dissection, in this disease, concern and management should be advocated in the early detection of Marfan syndrome.

The aim of this study was to investigate the efficacy of simvastatin to improved lipid profiles in hypercholesterolemic Korean patients. METHODS: From 25 hospitals in Korea, 478 hypercholesterolemic patients were enrolled from November 1996 to April 1998. The inclusion criteria was hypercholesterolemia over 240 mg/dl after diet therapy for 1 month or hypercholesterolemia over 220 mg/dl in patients with definite evidence of ischemic heart disease. Simvastatin 10mg was started and doubled up to 40mg if total cholesterol level remained higher than 200 mg/dl at monthly check. Of 478 subjects, 344 patients in whom study protocol was not violated were analyzed. RESULTS: Male to female ratio was 27:73 and 47% of the subjects were in 6th decade. Hypertension, coronary artery disease, and diabetes mellitus were present in 30, 10, and 4% of the subjects. Baseline lipid profile (mean of total cholesterol-LDL-HDL-triglyceride mg/dl) was 274-185-52-188. The dose of simvastatin for 3 months was 10/10/10mg in 61% of subjects, 10/20/20mg in 21%, 10/10/20mg in 7%, and 10/20/40mg in 12%. The change of total cholesterol level(before-4wk-8wk-12wk-withdrawal 4wk) was 274-209- 205-198-250, and the maximal reduction rate was 27%. The change of LDL-cholesterol was 185-123-116-110-159, with maximal reduction rate 39%. The change of HDL-cholesterol was 52-54-56-55-54, with maximal increase rate 9%. The change of tryglyceride was 188-161- 164-162-189, with maximal reduction rate 15%. The value before/after treatment of ApoA1, ApoB, and Lp(a) was 129/129, 138/83, and 9.3/10.7, respectively. The level of LDL-cholesterol at the end of treatment was below 100mg/dl in 36% of subjects, 100-130 in 45%, 130-160 in 16%, and over 160mg/dl in 4%. The reduction rate of LDL-cholesterol was different between subjects whose LDL decreased below 100 and those whose LDL did not decrease below 130mg/dl, which suggests the existence of the individual difference of responsiveness to simvastatin. There were only 3 subjects (0.9%) who showed increase of liver enzyme over 3 times as the upper normal limit. Conclusion: Simvastatin is effective in improving lipid profiles in hypercholesterolemic Korean patients without serious side effects.
