BACKGROUND AND OBJECTIVES: Hypercholesterolemia is a key factor in the development of atherosclerosis. We sought to evaluate the relation between hypercholesterolemia and plaque composition in patients with coronary artery disease. SUBJECTS AND METHODS: Study subjects consisted of 323 patients (mean 61.5 years, 226 males) who underwent coronary angiography and virtual histology-intravascular ultrasound examination. Patients were divided into two groups according to total cholesterol level: hypercholesterolemic group (> or =200 mg/dL, n=114) and normocholesterolemic group (<200 mg/dL, n=209). RESULTS: Hypercholesterolemic patients were younger (59.7+/-13.3 years vs. 62.6+/-11.5 years, p=0.036), than normocholesterolemic patients, whereas there were no significant differences in other demographics. Hypercholesterolemic patients had higher corrected necrotic core volume (1.23+/-0.85 mm3/mm vs. 1.02+/-0.80 mm3/mm, p=0.029) as well as percent necrotic core volume (20.5+/-8.5% vs. 18.0+/-9.2%, p=0.016) than normocholesterolemic patients. At the minimal lumen area site, percent necrotic core area (21.4+/-10.5% vs. 18.4+/-11.3%, p=0.019) and necrotic core area (1.63+/-1.09 mm2 vs. 1.40+/-1.20 mm2, p=0.088) were also higher than normocholesterolemic patients. Multivariate linear regression analysis showed that total cholesterol level was an independent factor of percent necrotic core volume in the culprit lesion after being adjusted with age, high density lipoprotein-cholesterol , hypertension, diabetes mellitus, smoking and acute coronary syndrome (beta 0.027, 95% confidence interval 0.02-0.053, p=0.037). CONCLUSION: Hypercholesterolemia was associated with increased necrotic core volume in coronary artery plaque. This study suggests that hypercholesterolemia plays a role in making plaque more complex, which is characterized by a large necrotic core, in coronary artery disease.

The treatment with nimodipine is recommended as an effective therapy for the delayed ischemic neurological deficits(DIND) caused by cerebral vasospasm following aneurysmal subarachnoid hemorrhage. The induced hypertension is also widely accepted as a treatment method to reverse the DIND caused by cerebral vasospasm. Therefore, the combination of these two regimens may be considered as a more effective treatment method for the DIND than nimodipine or induced hypertension alone. The authors performed this experimental study to clear up this subject. In a series of 60 adult rats, a surgical occlusion of the middle cerebral artery(MCA) was carried out by a microsurgical technique. The animals were divided into 4 groups as follows ; group I(N=15) : control group, group II(N=15) : nimodipine treated group, group III(N=15) : induced hypertension group, group II(N=15) : combined nimodipine treated with induced hypertension group. Group II animals were treated with an infusion of nimodipine intravenously(1 microgram/Kg/min), and group III animals were maintained high blood pressure(B.P) to 160 mmHg by an infusion of dopamine intravenously(2 microgram/Kg/min), and group IV animals were treated with an infusion of nimodipine and dopamine intravenously. All animals of each group were sacrificed at 6,12 and 24 hours after MCA occlusion. Then the brain slices were obtained and stained with triphenyltetrazolium chloride(TTC). The size of the infraction area was quantified by a computer image analysis system and the size of the infraction area compared among each groups. The results showed that each size of the infraction area according to sacrifice time at 6, 12 and 24 hours after MCA occlusion was significantly smaller in group II, III, IV than that of group I(p<0.05). The total size of the infraction area was significantly smaller in group II, III and IV than that of group I(group I vs. II vs. III vs. IV ; 13.23+/-2.60 vs. 9.17+/-2.23 vs. 10.24+/-2.23 vs. 8.85+/-2.23%, respectively. group I vs. II, III and IV : p<0.05). However, there was not noticed any significant difference in the size of the infarction area among group II, III and IV. This study concludes that the treatment of the combined nimodipine with induced hypertension has no more benefit for the improving infarction in the permanent focal ischemic model than nimodipine or induced hypertension treatment alone.

PURPOSE: This study describes how often complementary and alternative medical (CAM) therapies, what patterns of CAM therapies utilization, what types of CAM therapies and why CAM therapies are used in children and adolescent with chronic disease. METHODS: We interviewed and filled out questionnaires with parents of patients suffering from asthma, atopic dermatitis, congenital myopathy, epilepsy and so on from Mar 2004 to Aug 2004. RESULTS: Two hundred fifty two parents answered questionnaires; 160 cases (63.5 percent) had used CAM therapies. Utilization of CAM therapies according to each chronic disease was as follows: congenital myopathy (100 percent), atopic dermatitis (91.1 percent), asthma (72.5 percent), chronic diarrhea (50.0 percent), epilepsy (17.1 percent) etc. Types of CAM therapy were as follows: dietary supplement (31.1 percent), herb medicine (23.4 percent), massage (14.2 percent), acupuncture (4.6 percent) etc. Sixty four (40.0 percent) case underwent more than two types of CAM therapies simultaneously. One hundred thirty three (83.1 percent) case were asked through non-medical prescription. Ninety nine (61.9 percent) case were recognized positive effect of CAM therapies. Parents' and childrens' ages were influential factors in CAM therapies utilization: the older the parents and the younger the children, the higher the utilization. CONCLUSION: Although patients receive treatment with western medicine, many of them not only undergo CAM therapies, especially more than two types, but also recognize the positive effects of CAM therapies. As a result, we suggest that it is easy to use of CAM therapies, and the positive effects of CAM therapies are prominent, domestically. Therefore, medical approach and study about the effectiveness and side effects of CAM therapies is necessary to avoid the imprudent use of such therapies.

Digoxin is commonly used in treatment of various heart conditions, such as atrial fibrillation, atrial flutter, and sometimes heart failure. The therapeutic range of digoxin is narrow. Therefore, Digoxin toxicity is common. However, severe digoxin intoxication is uncommon. Many cases involving application of Digoxin immune Fab for digoxin intoxication in other countries have been reported. However, no cases have been reported in Korea. We reported on one case, a 34-year-old male with acute and severe digoxin intoxication who was treated with digibind(R). His chief complaint was gastrointestinal symptoms, including nausea and vomiting. Electrocardiography (ECG) showed third degree atrioventricular (AV) block. After an infusion of digibind(R), third degree AV block rhythm was changed to first degree AV block. Nowadays, we can obtain a digoxin antidote from the national poisoning information center. Therefore, we should actively consider application of Digoxin immune Fab in patients with severe digoxin intoxication.

BACKGROUND: Currently the most common treatment modality of refractory ascites in patients with liver cirrhosis was large volume paracentesis, but this procedure usually needed albumin infusion and occasionally developed unwanted complications. By reason of albumin shortage in Korea and occasional unfavorable complications, we studied the usefulness of dialytic ultrafiltration as an another treatment modality of refractory ascites. METHODS: Dialytic ultrafiltration was done in 10 patients (total 48 times) with liver cirrhosis or hepatocellular carcinoma. Two drainage conduit (via 16 gauge angio-catheter) of input and output were made by puncture of patient's right and left lower quadrant abdomen. The initial ultrafiltration rate of dialyser was 250mL/min. Ascitic fluid was removed continuously until the filtration rate down at 50mL/min. After ultrafiltration, ascitic fluid contained concentrated albumin and large molecules was reinfused via input conduit. Pre-treatment and post-treatment level of blood chemistry, plasma renin concentration, aldosterone, and electrolytes in serum; total protein and albumin in ascites were measured. During the ultrafiltration, we closely observed the change of blood pressure, heart rates and mental status. RESULTS: The mean ultrafiltration time was 231+/-28min, ultrafiltrated volume was 5.15+/-1.41 L. During dialytic ultrafiltration, patient's blood pressure and heart rate were stable and there was no change of mental status. After dialytic ultrafiltration, blood urea nitrogen level significantly decreased from 30.5+/-23.7mg/dL to 25.7+/-20.2mg/dL; serum aldosterone level decreased from 807.3+/-301.1pg/ml to 431.1+/-187.2pg/ml in serum (P<0.01). The albumin level in the ascitic fluid significantly increased from 0.67+/-0.28g/dL to 1.90+/-1.16g/dL (P<0.01). Plasma renin concentration level tend to decreased (P=0.06). The patient's serum total protein, albumin, electrolytes, and creatinine were not changed. Complications of dialytic ultrafiltration were peritonitis (one case) and hypotension (one case). But these unwanted complications were readily managed by adequate antibiotics and intravenous fluid therapy. CONCLUSION: The dialytic ultrafiltration can be used effectively without albumin infusion in the treatment of refrartory ascites in patients with advanced liver cirrhosis.

A bronchial artery (BA) aneurysm is a rare, life-threatening disease when it ruptures. Recently, we experienced a case of massive hemoptysis due to a BA aneurysm rupture in a pulmonary tuberculosis cavity, treated with BA embolization followed by surgical resection of the cavitary lesion. To our knowledge, this is the first case of a BA aneurysm associated with cavitary pulmonary tuberculosis.

PURPOSE: The purpose of this study was to compare prescription patterns and clinical features according to clinical departments in sedative-hypnotic intoxication. METHODS: This was a retrospective study of histories, substances of poisoning, acquisition routes, clinical courses, and outcomes of patients treated for acute intoxication in a single emergency medical center from January, 2011 to December, 2013. RESULTS: A total of 769 patients were treated for acute intoxication, 281 patients ingested sedative hypnotics during the study period. Among 281 patients, 155 patients were prescribed by psychiatric department and 80 patients were prescribed by non-psychiatric department. Benzodiazepines were more likely to be prescribed by psychiatrists, and zolpidem was preferred by non-psychiatrists (p<0.001). Non-psychiatrists were more likely to prescribe short acting benzodiazepines than psychiatrists (p<0.001). However, there was no statistically significant difference in the clinical outcomes, including prevalence of admission to ICU, ventilator care, and length of stay in ICU. In patients prescribed by non-psychiatrists, there were more patients prescribed without psychiatric diagnosis and diagnosed as major depression disorder after hospitalization. CONCLUSION: To promote rational prescribing of sedative hypnotics, proper psychiatric evaluation should be performed before prescribing, and educational programs including the contents of interactions and side effects of sedative hypnotics are needed.

A bezoar is a mass formed by the accumulation of digested food. A biliary bezoar, namely a bezoar formed in the bile duct, is rare, which occurs mostly in patients who formerly underwent cholecystectomy. It appears that incompetent sphincter produces occasional reverse flow of foreign bodies including undigested food from the alimentary canal into the bile tract. Surgical treatment is used for huge biliary bezoar which is too huge to be removed by nonsurgical treatment. Extracorporeal shock wave lithotripsy (ESWL) is mostly used to fragment renal or urinary calculi, but may be sparingly used against biliary calculi. This is to report the rare case of a patient with biliary bezoar who formerly underwent open cholecystectomy and choledocoduodenostomy. The patient's huge biliary bezoar was removed by ESWL and the successive execution of endoscopic retrograde cholangio pancreatography (ERCP). ESWL is expected to be a comparatively safe and convenient solution to huge biliary bezoars.

A multiplex PCR protocol was established to simultaneously detect major bacterial pathogens in olive flounder (Paralichthys olivaceus) including Edwardsiella (E.) tarda, Streptococcus (S.) parauberis, and S. iniae. The PCR assay was able to detect 0.01 ng of E. tarda, 0.1 ng of S. parauberis, and 1 ng of S. iniae genomic DNA. Furthermore, this technique was found to have high specificity when tested with related bacterial species. This method represents a cheaper, faster, and reliable alternative for identifying major bacterial pathogens in olive flounder, the most important farmed fish in Korea.
