The authors present a 67-year-old man who developed trigeminal neuralia caused by a dolichoectatic vertebrobasilar artery. Brain magnetic resonance imaging showed a tubular structure traversed the anterior surface of the sbrainstem, which compressed the left ven trilateral pons in the region of the trigeminal root entry zone. Vertebral angiography demonstrated a tortuous dilated vertebrobasilar artery. Microvascular decompression of the trigeminal nerve from the dolichoectatic vertebral artery and simultaneous selective trigeminal rhizotomy were performed. Postoperatively, the patient was relieved of pain but suffered a hearing deficit in the ipsilateral side.

BACKGROUND: A management protocol for hepatitis C virus (HCV) after liver transplantation (LT) has not been established in Korea. We therefore investigated HCV transplant protocols and post-transplant results from liver transplant centers in Korea. METHODS: The HCV protocol and medical data of individual cases from eight major liver transplant centers were compiled and analyzed. RESULTS: A post-transplant protocol biopsy was performed in only three centers. In these centers, HCV treatment was considered when pathological abnormalities were confirmed on the protocol biopsy (irrespective of liver function). In the other five centers, biopsies were performed when biochemical parameters were aggravated. Only two out of the eight centers performed preemptive or prophylactic therapy. A total of 5,663 adult LTs were performed between 2000 and 2010. HCV-related liver disease was responsible for 277 LTs (4.9%). Pre-transplant data were not available in many patients, including HCV genotype and serum HCV RNA level. Tacrolimus was more frequently used for initial maintenance immunosuppression than cyclosporine A (61.7% vs. 36.8%). Post-transplant HCV treatment was performed in 135 patients (48.7%). Sixty-seven recipients (24.2%) died during follow-up after LT and 11 HCV-related graft loss (4.0%) developed. The cumulative patient survival rate was 74.7% at 5 years and 67.9% at 10 years after LT. CONCLUSIONS: The HCV management protocol after LT varied markedly between the eight Korean transplant centers and a standard protocol did not exist. A nationwide multicenter study is required to investigate the most effective treatment for HCV after LT, with the goal of establishing the most effective standard protocol.

Cordyceps bassiana has long been used as an oriental medicine and reported to possess diverse biological activities. The fruiting bodies of Cordyceps bassiana was extracted with ethanol and then further fractionated with n-hexane, ethyl acetate, n-butanol and water. The butanol fraction from Cordyceps bassiana (CBBF) exhibited the most effective in anti-inflammatory activity in RAW 264.7 macrophages and the roles of CBBF on the anti-inflammation cascade in LPS-stimulated RAW 264.7 cells were studied. To investigate the mechanism by which CBBF inhibits NO, iNOS and COX-2, the activation of IκB and MAPKs in LPS-activated macrophage were examined. Our present results demonstrated that CBBF inhibits NO production and iNOS expression in LPS-stimulated RAW 264.7 macrophage cells, and these effects were mediated through the inhibition of IκB-α, JNK and p38 phosphorylation. Also, CBBF suppressed activation of MAPKs including p38 and SAPK/JNK. Furthermore, CBBF significantly suppressed LPS-induced intracellular ROS generation. Its inhibition on iNOS expression, together with its antioxidant activity, may support its anti-inflammatory activity. Thus Cordyceps bassiana can be used as a useful medicinal food or drug for further studies.

OBJECTIVES: The aim of this study was to investigate the relationship between job stress and the willingness of male workers in small and medium scale industry to cease smoking. METHODS: A structured self-reported questionnaire was used to assess each respondent's socio-demographics, job stress, and the will to cease smoking. A KOSS (Korean Occupational Stress Scale)- based questionnaire survey was conducted which targeted 4,435 male workers at 69 small and medium scale industries. 2,840 men returned these questionnaires with 1,663 of them being smokers. We analyzed 1,345 of the smoker returns. We estimated the relationship between the will to cease smoking and the employee job stress factors using logistic regression analyses. RESULTS: After adjusting for education, exercise, and tobacco use per day, the logistic regression analysis revealed a significantly positive association with the will to cease smoking and job stress. The odds ratios regarding insufficient job control were at 1.69 (95% CI, 1.26~2.27), organizational system at 1.37 (95% CI, 1.03~1.82), and lack of reward at 1.37 (95% CI, 1.03~1.82). CONCLUSIONS: These results indicated that job stress may play a significant role in the will to cease smoking. Further preventive efforts and studies are needed in order to reduce job stress.

PURPOSE: Serious complications from snake bite envenomization are relatively rare in Korea. According to standrad treatment guidelines for local and systemic injuries, antivenin is not recommended for snake bite cases when victims show minimal clinical symptoms. However, there are no published stidies about the effectiveness of antivenin treatment in such cases in Korea. In order to provide actual documentation to support a standard for treatment, we evaluated the effectiveness of antivenin use by comparing clinical outcomes in snake bite patients exhibiting minimal clinical symptoms (traditional snake bite severity grades 0 and I). METHODS: We retrospectively reviewed 140 snake bite cases of patients with minimal clinical symptoms who visited the emergency departments of Chungnam National University Hospital, Cheonan Medical Center, and Chungnam Seosan Medical Center in Korea from January 2000 to December 2006. We categorized the patients into antivenin (group 1) and non-antivenin (group 2) treatment groups. We compared clinical outcomes and characteristics of the two groups. RESULTS: Neither demographic factors nor clinical outcomes showed statistical significance between the groups. CONCLUSION: In case of snake bite victims in Korea, antivenin treatment should not generally recommended as treatment for victims exhibiting minimlal clinical symptoms.

BACKGROUND AND OBJECTIVES: We hypothesized that fetal echocardiography (echoCG) is an accurate diagnostic tool reflecting well postnatal echoCG findings and outcomes. SUBJECTS AND METHODS: We reviewed the medical records of 290 pregnant women, including 313 fetuses, who were examined by fetal echoCG at the Seoul National University Children's Hospital from January 2008 through April 2011. RESULTS: The mean gestational age at diagnosis was 26.2+/-5.2 weeks. The mean age of mothers at diagnosis was 31.7+/-3.8 years. We identified indications for fetal echoCG in 279 cases. The most common indication was abnormal cardiac findings in obstetrical screening sonography (52.0%). Among the 313 echoCG results, 127 (40.6%) were normal, 13 (4.2%) were minor abnormalities, 35 (11.2%) were simple cardiac anomalies, 50 (16.0%) were moderate cardiac anomalies, 60 (19.2%) were complex cardiac anomalies, 16 (5.1%) were arrhythmias, and 12 (3.8%) were twin-to-twin transfusion syndrome. The most common congenital heart disease was tetralogy of Fallot (23 fetuses, 15.9%). One hundred forty-eight neonates were examined by echoCG. We analyzed differences between fetal echoCG and postnatal echoCG. In 131 (88.5%) cases, there was no difference; in 15 (10.1%), there were minor differences; and in only 2 (1.4%) cases, there were major differences. CONCLUSION: There is a recent increase in abnormal cardiac findings of obstetric ultrasonography screenings that indicate fetal echoCG. Fetal echoCG is still a good, accurate diagnostic method for congenital heart disease.

BACKGROUND AND OBJECTIVES: Vascular rings refer to anomalies of the great arteries that cause respiratory or feeding problems. The purpose of this study was to analyze a series of patients with vascular rings and evaluate associated risk factors for mortality. SUBJECTS AND METHODS: A retrospective review of all patients identified with vascular rings between 1997 and 2010 in the Seoul National University Children's Hospital. RESULTS: Thirty-five patients were diagnosed with vascular rings (median age at diagnosis, 7 months). The vascular rings of 32 patients were confirmed by cardiac computed tomography or magnetic resonance imaging. The types of vascular rings were: a double aortic arch in ten patients, a right aortic arch with persistent left ligamentum arteriosum in seven, an aberrant subclavian artery in seven, a pulmonary sling in eight, and others types in three patients. Eleven patients were asymptomatic. Gastrointestinal and respiratory symptoms were seen in ten and sixteen patients, respectively. Associated cardiovascular anomalies were present in fifteen patients. Twenty patients with definite symptoms underwent surgical treatment. The median interval between diagnosis and operation was 6 days. Four patients eventually died; three deaths were associated with complex heart diseases, and one had pulmonary artery sling with severe tracheal stenosis. Only the presence of a complex heart disease significantly influenced mortality (p=0.002). CONCLUSION: Vascular rings include several types of anomalies, each with a different prognosis and symptoms. The presence of a complex heart disease was significantly associated with mortality. Early diagnosis and timely surgery in symptomatic patients are essential.

Cardiac resynchronization therapy (CRT) has been proven its value in adult patients with congestive heart failure of low ejection fraction and wide QRS duration. Contrast to adult patients, CRT has been rarely applied for young patients. We report on a 9-yr-old boy with progressive left ventricular (LV) dilatation and dysfunction following chronic VVI pacemaker therapy for congenital complete atrioventricular block associated with maternal anti-SSA/Ro and SSB/La antibody. His LV dysfunction was improved after epicardially established CRT.

BACKGROUND AND OBJECTIVES: Milrinone is often used in children to treat acute heart failure and prevent low cardiac output syndrome after cardiac surgery. Due to the lack of studies on the long-term milrinone use in children, the objective of this study was to assess the safety and efficacy of the current patterns of milrinone use for > or =3 days in infants and children with heart diseases. SUBJECTS AND METHODS: We retrospectively reviewed the medical records of patients aged <13 years who received milrinone for > or =3 days from January 2005 to December 2012. Patients' characteristics including age, sex, height, weight, and body surface area were recorded. The following parameters were analyzed to identify the clinical application of milrinone: initial infusion rate, maintenance continuous infusion rate, total duration of milrinone therapy, and concomitantly infused inotropes. The safety of milrinone was determined based on the occurrence of adverse events such as hypotension, arrhythmia, chest pain, headache, hypokalemia, and thrombocytopenia. RESULTS: We assessed 730 admissions (684 patients) during this period. Ventricular septal defects were the most common diagnosis (42.4%) in these patients. Milrinone was primarily used after cardiac surgery in 715 admissions (97.9%). The duration of milrinone treatment varied from 3 to 64.4 days (> or =7 days in 149 admissions). Ejection fraction and fractional shortening of the left ventricle improved in patients receiving milrinone after cardiac surgery. Dose reduction of milrinone due to hypotension occurred in only 4 admissions (0.5%). Although diverse arrhythmias occurred in 75 admissions (10.3%), modification of milrinone infusion to manage arrhythmia occurred in only 3 admissions (0.4%). Multivariate analysis indicated that the development of arrhythmia was not influenced by the pattern of milrinone use. CONCLUSION: Milrinone was generally administered for > or =3 days in children with heart diseases. The use of milrinone for > or =3 days was effective in preventing low cardiac output after cardiac surgery when combined with other inotropes, suggesting that milrinone could be safely employed in pediatric patients with heart diseases.

BACKGROUND AND OBJECTIVES: We studied the results of patient management for left isomerism (LI) and sought to determine factors that may influence survival and prognosis. SUBJECTS AND METHODS: We reviewed the medical records of 76 patients who were compatible with LI criteria between 1982 and 2014. RESULTS: Of the total study population, 29 patients (38.1%) had functional univentricular heart disease, 43 patients (56.5%) had cardiac anomalies suitable for biventricular hearts, and four patients (5.2%) had normal heart structure. Extracardiac anomalies were noted in 38.1% of the study population, including biliary atresia in 7.8% of all patients. Of the 25 patients who underwent Kawashima procedures, 24.0% developed pulmonary arteriovenous fistulas (PAVFs). During the median follow-up period of 11.4 years (range: 1 day to 32 years), 14 patients died. The 10-year, 20-year, and 30-year survival rates were 87%, 84%, and 76%, respectively. Preoperative dysrhythmia and uncorrected atrioventricular valve regurgitation were significantly associated with late death. There was no significant difference in the number of surgical procedures and in survival expectancy between patients in the functional single-ventricle group and in the biventricular group. However, late mortality was higher in functional single-ventricle patients after 18 years of age. CONCLUSION: Patients with LI need to be carefully followed, not only for late cardiovascular problems such as dysrhythmia, valve regurgitation, and the development of PAVFs, but also for noncardiac systemic manifestations.
