Wegener`s granulomatosis (WG) is a multisystem disorder of unknown origin characterized by necrotizing granulomatous vasculitis. WG usually affects the upper respiratory tract, lungs, and kidneys with focal glomerulonephritis, but almost any organ can be affected. The ureter is primarily an unusual location for lesions of WG. A 30-year-old woman presented with intermittent right flank pain and hematuria. A renal ultrasound demonstrated unilateral hydronephrosis and a retrograde pyelography revealed a filling defect at right mid ureter and a computed tomography displayed marked concentric thickening of the right ureteral wall which was mimicking ureteral tumor. At nephroureterectomy, the right ureter was found to be obstructed by dense, intramural fibroinflammatory reaction. There was a necrotizing granulomatous vasculitis in the muscle layer of the ureter. Our case represents the rare occurrence of WG presenting ureteral bstruction.

BACKGROUND: Partially paralyzed patients may be placed in the risk of pharyngeal dysfunction. Bupivacaine acts as acetylcholine receptor ion channel blocker and may synergistically interact with rocuronium to augment NM blockade. Thus, this study aims to elucidate whether or not, at a therapeutic concentration, bupivacaine by itself may cause NM blockade and reduce an effective concentration of rocuronium. METHODS: Twenty-two left phrenic nerve-hemidiaphragms (Male SD rats, 150-250 g) were hung in Krebs solution. Three consecutive ST, 0.1 Hz and one TT, 50 Hz for 1.9 s were obtained before drug application and at each new drug concentration. A concentration of bupivacaine in Krebs solution (n = 5) was cumulatively increased by way of 0.01, 0.1, 1, (1, 2, 3, 4, 5, 6, 7) x 10 microM. In a Krebs solution, pre-treated with bupivacaine 0 (n = 5), 0.1 (n = 5), 1.0 (n = 5), 10 (n = 2) microM, and then concentrations of rocuronium were cumulatively increased by way of 1, 3, 5, 7, 9, 12, 14, 16, 18, 20 microM. EC for each experiment were determined by a probit. The EC50's of rocuronium were compared using a Student's t-test with Bonferroni's correction. Differences were considered significant when P < 0.05. RESULTS: The potency of bupivacaine for normalized TF was 11.4 (+/- 1.1) microM. Below 30 microM of bupivacaine, the single twitch potentiation sustained despite the development of tetanic fade and partial inhibition of PTT. Bupivacaine significantly facilitated the NM blockade induced by rocuronium. CONCLUSIONS: Clinicians should be aware that bupivacaine by itself at its therapeutic concentration inhibit NM conduction and enhances rocuronium-induced muscle relaxation.

BACKGROUND: Sevoflurane and propofol-remifentanil have been known to cause less organ toxicities. However, there are few reports comparing the hepatic and renal effects of both anesthetic regimens. This study was intended to compare sevoflurane with propofol-remifentanil on postoperaitve hepatic and renal function in patients who underwent laparoscopic and open abdominal surgeries retrospectively. METHODS: Adult patients who had undergone abdominal surgeries were enrolled to conduct retrospective analyses. Total number of 717 patients was largely divided into a laparoscopic surgery (n = 309) and an open surgery (n = 408). The each of laparoscopic and open surgery was divided into a sevoflurane group (Group SEVO) and a propofol-remifentanil group (Group TIVA). Hepatic and renal markers were measured before the operation and on the first and second postoperative day. RESULTS: Serial changes of postoperative hepatic and renal markers in the laparoscopic and open surgeries were shown in similar patterns between the Group SEVO and the Group TIVA. And there were no statistical differences in the incidence of clinically significant increases in serum SGOT, SGPT, and Cr. CONCLUSIONS: As sevoflurane and propofol-remifentanil did not show influence on the hepatic and renal function, they may be used safely on patients undergoing the abdominal surgeries.

BACKGROUND: Magnesium, ropivacaine, gentamicin, and rocuronium block neuromuscular (NM) transmission by different mechanisms. Therefore, concurrent administration of these agents may induce prolonged muscle paralysis via synergistic interaction. This study investigated the efficacy and safety of NM block caused by the administration of high concentrations of magnesium in combination with ropivacaine, gentamicin, and rocuronium. METHODS: Eighty-three left phrenic nerve-hemidiaphragms from male SD rats (150-250 g) were hung in Krebs solution. Three consecutive single twitch tension (ST, 0.1 Hz) and one tetanic tension (TT, 50 Hz for 1.9 s) were obtained before drug application and at each new drug concentration. The concentration of MgCl2 and MgSO4 in Krebs solution was increased until an 80 to 90% reduction in ST was reached. To test the effects of combinations of NM agents, a Krebs solution was premixed with MgCl2 alone, MgCl2 and ropivacaine, or MgCl2, ropivacaine, and gentamicin. The concentration of ropivacaine, gentamicin, or rocuronium was then progressively increased until an 80 to 90% reduction in ST was reached. The effective concentrations were estimated with a probit model. RESULTS: The potency of MgCl2 was greater than that of MgSO4, and pretreatment with MgCl2 increased the potency of gentamicin and rocuronium. Unexpectedly, MgCl2 did not potentiate ropivacaine, and the potency of gentamicin and rocuronium failed to show an increase when premixed with 0.5 microM ropivacaine. CONCLUSIONS: The concomitant administration of high concentrations of magnesium and ropivacaine together with clinically relevant concentrations of gentamicin or rocuronium potentiated NM blockade but not with clinically relevant concentrations of ropivacaine.

BACKGROUND/AIMS: Although controversial, probiotics and dietary fiber are commonly used for patients with irritable bowel syndrome (IBS). We evaluated the effects of multistrain probiotics on the symptoms of IBS to determine whether the addition of dietary fi ber had an additive effect on constipation-predominant IBS. METHODS: A total of 142 participants who met the Rome III criteria were recruited and randomized into a control group or a test group. Participants in the control group received multistrain probiotic fermented milk with Streptococcus thermophilus, Lactobacillus acidophilus and Bifidobacterium infantis; the participants in the test group received the same probiotic fermented milk mixed with dietary fi ber such as sea tangle extracts, radish extracts and glasswort extracts. The patients were treated for four weeks. RESULTS: Most of the symptoms of IBS, with the exception of fl atulence, stool consistency, and frequency of defecation, signifi cantly improved in both groups. In the analysis of IBS subtypes, especially constipation-predominant IBS, the frequency and duration of defecation and straining at stool were improved more in the test group than in the control group. CONCLUSIONS: Dietary fiber had additive benefits for the symptoms of constipation, especially in constipation-predominant IBS.

BACKGROUND AND OBJECTIVES: Recent advances in trans-radial coronary intervention (TRI) have shown a reduction in patient's morbidity. However, the role of TRI for a chronic total occlusion (CTO) is not well established. The aim of this study was to assess the safety and feasibility of TRI for a CTO. SUBJECTS AND METHODS: Sixty-three successive CTO lesions of more than 2 months duration were prospectively included in this registry between April 2002 and November 2003. Guiding catheters with strong back-up, stiff guide wires and supportive infusion catheters were actively used. The angiographic and procedural characteristics were prospectively evaluated. RESULTS: There were 45 male and 18 female patients, with a mean age of 59.8+/-9.5 years. The most common clinical diagnosis was stable angina (95.2%). The mean duration of the occlusions was 10.3+/-1.6 months. Procedural success was achieved in 53 lesions (84.1%). No cases were crossed over to transfemoral procedure. The most common cause of procedural failure was guide wire passage failure (7 lesions). The mean duration of occlusions was significantly longer in the failure group (7.5+/-1.1 versus 24.8+/-6.5 months, p<0.001). Bridging collateral vessels, long occlusions, calcification at lesion sites, a side branch at the occlusion site and blunt entry morphology were also statistically significant predictors for procedural failure. Procedure-related complications were noted in 6 patients (9.8%), which included coronary perforations (3.3%), severe dissections (3.3%), arrhythmia (1.6%) and branch artery occlusion (1.6%). No patients suffered from local complications, such as hematoma or radial artery occlusion. CONCLUSION: TRI for a CTO seems to be safe and feasible, with acceptable success and complication rates.

BACKGROUND/AIMS: Exclusion of liver disease from other causes such as autoimmune hepatitis is necessary for diagnosis of nonalcoholic fatty liver disease (NAFLD). However, there has been no study on the prevalence and significance of autoantibodies in the patients with clinically suspected NAFLD in Korea, where hepatitis B is endemic and autoimmune hepatitis is relatively uncommon. METHODS: We prospectively tested for anti-nuclear antibody (ANA), anti-smooth muscle antibody (ASMA), and anti-mitochondrial antibody (AMA) in 135 serially enrolled patients with suspected NAFLD. We compared the clinical characteristics and biochemical indices of the ANA-positive or ASMA-positive group with those of the autoantibody-negative group. RESULTS: Sixteen patients (11.8%) had serum autoantibodies; there was ANA in 8 patients (5.9%), ASMA in 7 (5.1%), and AMA in 2 (1.5%). Both ANA and AMA were positive in one patient. The ANA-positive or ASMA-positive group showed an older age (49.5+/-13.0 vs. 42.0+/-10.9 years, respectively, P=0.018) and higher levels of serum globulin (3.1+/-0.4 vs. 2.9+/-0.4 g/dL, respectively, P=0.037), compared with the autoantibody-negative group. Two cases with positive ANA or ASMA fulfilled the diagnostic criteria for probable autoimmune hepatitis and two cases with positive AMA were suspected as primary biliary cirrhosis. CONCLUSIONS: These findings suggest that autoantibodies could be found in some patients with suspected NAFLD in Korea, AMA-positivity or ASMA-positivity could be associated with old age and high serum globulin, and some of the autoantibody-positive cases could be diagnosed as autoimmune hepatitis or primary biliary cirrhosis. Further studies are necessary to clarify the clinical significance of autoantibody positivity in those patients.

PURPOSE: To investigate associations between dyspnea and clinical outcomes in patients with non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: From 2001 to 2014, we retrospectively reviewed the prospective lung cancer database of St. Paul's Hospital at the Catholic University of Korea. We enrolled patients with NSCLC and evaluated symptoms of dyspnea using modified Medical Research Council (mMRC) scores. Also, we estimated pulmonary functions and analyzed survival data. RESULTS: In total, 457 NSCLC patients were enrolled, and 259 (56.7%) had dyspnea. Among those with dyspnea and whose mMRC scores were available (109 patients had no mMRC score), 85 (56.6%) patients had an mMRC score <2, while 65 (43.3%) had an mMRC score ≥2. Significant decreased pulmonary functions were observed in patients with dyspnea. In multivariate analysis, aging, poor performance status, advanced stage, low forced expiratory volume in 1 second (%), and an mMRC score ≥2 were found to be significant prognostic factors for patient survival. CONCLUSION: Dyspnea could be a significant prognostic factor in patients with NSCLC.

Isolated infective endocarditis in the native pulmonary valve is unusual in non-intravenous drug user. Intravenous drug abuse, alcoholism, sepsis, catheter related infections and congenital heart diseases account for the majority of predisposing factors. We report a case of patent ductus arteriosus complicating infective endocarditis involving pulmonary valve. A 24-year-old female was admitted with fever of unknown origin Physical examination revealed continuous murmur at left 2nd intercostals space. Transthoracic and transesophageal echocardiography was performed and patent ductus arteriosus and vegetation at the pulmonary valve were noted. Chest CT scan revealed multiple patch infiltrate suggestive of septic emboli. After 4 weeks of antibiotic treatment, she had no clinical signs of fever, and blood culture be negative. Percutaneous trans-catheter closure of patent ductus arteriosus was done after 2 months.
