OBJECTIVE: We wanted to evaluate the therapeutic efficacy of the percutaneous balloon dilatation and large profile catheter maintenance method for the management of patients with anastomotic biliary strictures following liver transplant. MATERIALS AND METHODS: From May 1999 to June 2003, 12 patients with symptomatic benign biliary stricture complicated by liver transplantation were treated with the percutaneous balloon dilatation and large profile catheter maintenance method (1-6 months). The patients were eight males and four females, and their ages ranged from 20 to 62 years (mean age: 44 years). Ten patients underwent living donor liver transplantation and two underwent cadaveric liver transplantation. Postoperative biliary strictures occurred from two to 21 months (mean age: 18 months) after liver transplantation. RESULTS: The initial technical success rate was 92%. Patency of the bile duct was preserved for eight to 40 months (mean period: 19 months) in 10 of 12 (84%) patients. When reviewing two patients (17%), secondary balloon dilatations were needed for treating the delayed recurrence of biliary stricture. In one patient, no recurrent stenosis was seen during the further 10 months follow-up after secondary balloon dilatation. Another patient did not response to secondary balloon dilatation, and he was treated by surgery. Eleven of 12 patients (92%) showed good biliary patency for 8-40 months (mean period: 19 months) of follow-up. CONCLUSION: The percutaneous balloon dilatation and large profile catheter maintenance method is an effective therapeutic alternative for the treatment of most biliary strictures that complicate liver transplantation. It has a high success rate and it should be considered before surgery.

OBJECTIVE: To determine the value of selective intra-arterial calcium stimulation with hepatic venous sampling using serum insulin and C-peptide gradients for the preoperative localization of insulinomas. MATERIALS AND METHODS: Seven consecutive patients [three men and four women aged 15-77 (mean, 42.7) years] with hypoglycemia underwent selective intra-arterial calcium stimulation in conjunction with hepatic venous sampling. Insulin gradients were calculated by an individual blinded to all other preoperative imaging studies and operative findings. In all patients except one, C-peptide gradients were also analyzed. The results were compared with the preoperative findings of ultrasonography, computed tomography, arteriography and endoscopic ultrasonography, as well as with the intraoperative findings of ultrasonography and palpation at surgery. RESULTS: Eight insulinomas (mean diameter, 12.5 mm) were diagnosed after surgery. In six patients, the calcium stimulation test with insulin gradients allowed accurate localization of the pathologic source of insulin secretion. Both C-peptide and insulin gradients substantially increased diagnostic accuracy. In one patient, C-peptide gradients were more helpful than insulin gradients for tumor localization. CONCLUSION: Selective intra-arterial calcium stimulation with hepatic venous sampling is a highly accurate and safe method for the preoperative localization of insulinomas. Additional C-peptide gradients seem to be helpful in assessing tumor location, but further study is needed.

Acute eosinophilic pneumonia is reported as a specific disease entity. But, it is different from chronic eosinophilic pneumonia in its onset, clinical course and recurrence. Badesh et al reported the following diagnostic criteria os acute eosinophilic pneumonia a less than one-month history of symptoms prior to diagnosis, no evidence of asthma, the absence of other organic disease, no obvious etiology and an evidence of recurrent disease. We experienced a case of acute eosinophilic pneumonia in 37 old male. Pathologically eosinophilic pneumonia is confirmed and other features meet Badesh's criteria.

OBJECTIVE: To assess the efficacy and safety of a "mini-perc" technique of percutaneous nephrolithotomy using a 14-Fr peel-away sheath for the removal of pyelocaliceal stones, and to determine appropriate inclusion criteria. MATERIALS AND METHODS: From July 1999 to June 2002, the medical records and radiographic images of 72 patients who underwent the "mini-perc" technique of percutaneous nephrolithotomy with a 14-Fr peel-away sheath, were reviewed to determine clinical history, stone characteristics, immediate stone free rate, final stone free rate after additional procedures, complications, and hospital stay. We also analyzed the effect of the longest stone diameter, the cumulative longest diameter of stones, the cumulative stone burden, and the stone density on the immediate stone free rate using a Fisher exact test. RESULTS: The only major complication, arterial bleeding, occurred in a patient with Child A liver cirrhosis and was successfully treated by embolization with coils and a gelatin sponge. The immediate stone free rate was 80.6 %, which was significantly influenced by stone diameter but not stone density. The mean hospital stay after the procedure was 3.97 days. CONCLUSION: The "mini-perc" technique of percutaneous nephrolithotomy, which uses the 14-Fr peel-away sheath, is a safe and effective modality for treating renal calculi.

OBJECTIVE: To investigate whether the uterine artery pulsatility index (UtA PI) of hypertensive pregnancies is higher than that of normal pregnancies in the puerperium, as well as in the antepartum period. METHODS: The UtA PI was measured in hypertensive (group 1) and normal pregnancies (group 2) during antepartum, immediate postpartum or late postpartum periods. Using the transvaginal approach, the bilateral uterine artery indices were measured. RESULTS: One hundred twenty-two women were enrolled: group 1, hypertensive disease in pregnancy (11 cases in antepartum, 13 cases in immediate postpartum and 10 cases in late postpartum period); group 2, normal pregnancies (32 cases in antepartum, 29 cases in immediate postpartum and 27 cases in late postpartum). In antepartum and immediate postpartum periods, the mean UtA PI and the proportion of cases with an early diastolic notch were higher in group 1 than in group 2 (antepartum mean UtA PI, 1.14 in group 1 vs. 0.68 in group 2, P<0.001; early diastolic notch, 46% vs. 9%, P<0.05; immediate postpartum mean UtA PI, 1.30 vs. 1.08, P<0.05; early diastolic notch, 85% vs. 48%, P<0.05). In late postpartum period, the mean value of UtA PI of group 1 was still higher than that of group 2, although the proportion of cases with an early diastolic notch was not different (mean UtA PI, 1.43 vs. 1.20, P<0.05; early diastolic notch, 60% vs. 52%, P=0.73). CONCLUSION: The UtA PI in hypertensive pregnancies was still higher than normal pregnancies in puerperal periods, suggesting that more than several weeks are required to resolve increased uterine artery vascular impedance.

PURPOSE: This study aimed to evaluate the ultrasonographic findings for various types of vascular closure devices (VCDs) immediately after the angiographic procedure and at 6-month follow-up. METHODS: We included 18 VCDs including Angio-Seal (n=4), FemoSeal (n=8), ExoSeal (n=3), Perclose (n=2), and StarClose (n=1) in this study. Four patients were implanted with 2 VCDs at the each side of bilateral femoral arteries, while the remaining 8 patients were inserted 1 VCD at the right femoral artery. Ultrasonography was performed within 10 days and at approximately 6 months after the angiographic procedure. Ultrasonographic morphology of the attached VCD and its relationship with the arterial wall were analyzed. RESULTS: Initial ultrasonography revealed the attached VCD as the relevant unique structure with successful deployment and hemostasis. Follow-up ultrasonography demonstrated partial absorption of hemostatic materials in cases of Angio-Seal (n=3), FemoSeal (n=5), and ExoSeal (n=3), changes in the soft tissue surrounding the femoral artery in case of Angio-Seal (n=1), arterial intimal hyperplasia in cases of FemoSeal (n=3), and no gross changes as compared with the initial ultrasonographic findings in cases of Perclose (n=2) and StarClose (n=1). CONCLUSION: Initial ultrasonographic evaluation reflected the unique structure of each VCD, with most of them being easily distinguishable. Follow-up ultrasonography revealed various changes in the affected vessels.

Churg-Strauss Syndrome is a disorder of hypereosinophilia and systemic vasculitis in subjects with asthma and allergic rhinitis. Clinically, a multiple organ system can be involved with various manifestations of disease of lung, heart, skin, musculoskeletal system, nervous system, gastrointestinal and hepatobiliary tract. We experienced a case of Churg- Strauss syndrome presenting as the appendicitis and the lower gastrointestinal bleeding in a 37-year-old male patient with acute lower abdominal pain. He also showed peripheral eosinophilia, bronchial asthma, and mononeuritis multiplex. He initially received a high dose corticosteroid and was maintained with low doses of corticosteroid, cyclophosphomide and exchange plasmapheresis.

OBJECTIVE: Recently, the prevalence of gall stone related with metabolic syndrome is increasing in Korea. The aim of this study was to reveal a relationship between components of metabolic syndrome and the development of gall bladder stones. METHODS: Among the subjects who visited a health promotion center of Soonchunhyang University Hospital from March 2009 to March 2010, a total of 5,201 adults were examined. Among them, the final 5,052 (male 3,403, female 1,649) adults were included. Sex, age, body mass index, waist circumference, blood pressure, fasting blood glucose, total cholesterol, triglyceride, high density lipoprotein-cholesterol levels, and the presence of gall stones were measured. Metabolic syndrome was defined by criteria of 2004 American Heart Association/Updated National Cholesterol Education Program Adult Treatment Panel III. Analyses were adjusted by age and sex. RESULTS: This study showed that the prevalence of gall stone was 1.6% and metabolic syndrome was 19.3%. The results didn't show an association between gall stone risk and components of metabolic syndrome. But gall stone risk was increased according to aging, high total cholesterol in the abnormal body mass index group. In normal body mass index group, waist circumference was related with the development of gall stone. Total cholesterol level was related with the development of gall stone in overweight group. CONCLUSION: This study showed total cholesterol levels and waist circumference related with prevalence of gall stone in specific body mass index group.

We retrospectively reviewed the medical records of 284 patients with neutropenic fever following chemotherapy for acute leukemia at the Catholic Hematopoietic Stem Cell Transplantation Center from January 1998 to December 1999, to identify prognostic factors for infection related mortality. Twenty-eight patients died of infections. There was no difference in median age, gender ratio, or underlying disease between the dying and surviving groups. Bacteria were the main pathogens following chemotherapy, and Gram positive organisms predominated in the dying group. Pneumonia and sepsis were the main causes of death. There were 72 cases of invasive fungal infection and their mortality was 27.8%. Invasive fungal infection and previous history of fungal infection were independent prognostic factors for outcome. Recovery from neutropenia was the significant protective factor for mortality. In conclusion, the prognostic factors identified in this study could be useful for deciding on more intensive treatment for those patients at greater risk of death. To our knowledge, this is the first Korean study delineating prognostic factors in acute leukemic patients with infectious complications.

The nocardiae are gram-positive, aerobic actinomycetes causing opportunistic infections in compromised hosts, such as recipients of solid organ transplants, patients with AIDS, and patients with cancer receiving immunosuppressive therapy, and those with chronic illnesses. Because cellular immunity and neutrophil function are critical for the clearance of Nocardia, frequent infection with the organism would be expected amongmarrow recipients, but reports of nocardiosis are surprisingly rare among these patients. We report a case of nocardiosis sixteen months after an allogenic bone marrow transplantation. The patient was successfully treated with imipenem and amikacin for 4 weeks and then with oral trimethoprim-sulfamethoxazole.
