PURPOSE: Kawasaki disease involves acute febrile systemic vasculitis that can cause a variety of symptoms by affecting various organs. Here, we aimed to evaluate the prevalence, causes, and prognosis of sensorineural hearing loss (SNHL) occurring in children with Kawasaki disease. METHODS: Patients who were diagnosed with Kawasaki disease and received inpatient treatment in the Pediatrics Department at one of three university hospitals in Daegu city from February 2012 to September 2012 were enrolled in the study. The clinical features, hematological results, echocardiography results, audiometry results, and aspirin and salicylic acid serum levels of the patients were evaluated. RESULTS: Of the 59 children enrolled in the study, three showed mild bilateral SNHL on audiometry tests conducted after 48 hours of defervescence; these patients demonstrated normal patterns of recovery on follow-up tests 8 weeks later. Aspirin serum levels were significantly higher in the SNHL group after 48 hours of afebrile condition with high dose aspirin intake (P=0.034). However, no significant differences were found in other laboratory tests or for fever duration (P>0.05). Upon echocardiography, coronary artery abnormality was observed in 9 cases, but none of these patients showed hearing loss. CONCLUSION: The results indicate that SNHL in children with Kawasaki disease might occur during treatment of the acute phase; this SNHL usually involves mild bilateral hearing loss and recovers naturally. However, this study suggests that determination of the causes and clinical implications of hearing loss in Kawasaki disease requires long-term follow-up studies with more cases.

In 1, 345 patients suspected of having pancreatic or biliary tract disease, 23 patients were shown to have biliary ascariasis demonstrated by endseopic retrograded cholangiopancreatog raphy, at Kwang Ju Christian Hospital from Sep. 1976 to Aug. 1983. Authors report the clinical study and ERCP finding of 23 cases of biliary ascariasis. The result were as follows. 1) Out of 1,345 cases of ERCP, biliary ascariasis were 28 cases, The ascaris were found in CHD & IHD in 21 cases, and 2 casee were found in Ampulla of Vater. 2) There was no specifia age incidence and male to female ratio was 1: 1.9, 3) The disease was more prevalent in spring & summer, and more prevalent in rural area than urban area. 4) The chief eomplaints were RUQ and epigastric abdominal pain. The cases which were admitetted within 2weeks of onset were 16 cases. 5) Ascaris in biliary tract were removed by operation in 14 cases, and EST were performed in 5 cases. Two cases werere moved by DORMIA basket under the endoscopic direct visualization. 6) We report E.S.T. as a new therapeutic method of biliary ascariasis.

BACKGROUND AND OBJECTIVES: Kawasaki disease is an acute systemic vasculitis of which pathogenesis suspected is caused by immune dysregulation. The goal of this study is to evaluate the activation pattern of T helper cell type 1 (Th1) and T helper cell type 2 (Th2) in patients with Kawasaki disease. SUBJECTS AND METHODS: Prospective study of 60 patients (male 36, female 24) with diagnosis of Kawasaki disease were enrolled. One hundred and eighty blood samples from these patients were collected according to the different clinical stages {before initial intravenous immunoglobulin (IVIG), 5 days after initial IVIG, 2 months after initial IVIG}. The plasma level of Th1 cytokines; interferon-gamma (IFN-gamma) & interleukin (IL)-2 and Th2 cytokines; IL-4 & IL-10 were measured by enzyme-liked immunosorbent assay. RESULTS: In all patients, the plasma level of Th1 cytokines (IFN-gamma, IL-2) and Th2 cytokines (IL-4 and IL-10) were markedly elevated during the acute stage of Kawasaki disease. Since then, the plasma level of all these cytokines decreased significantly along with the process of clinical stages. Regardless of the existence of coronary artery lesion or no response to initial IVIG treatment, there were no significant differences between them. CONCLUSION: These data suggest that both Th1 and Th2 cells may be activated simultaneously during the acute stage of Kawasaki disease. Further studies are therefore required to establish the difference of activation pattern of T helper cells between Kawasaki disease and other inflammatory diseases.

Hepatoblastoma is a hepatic tumor predominantly occurring in children. The usual site of metastasis is the lung. There are only several reports worldwide on the distant metastasis of hepatoblastoma to the central nervous system in children. Only one reported case showed survival of a patient after multiple resections of a recurrent brain lesion. Involvement of the cardiovascular system has been reported in the medical literature. Lesions almost always involve the right-side of the heart. We report a case of recurrent hepatoblastoma at multiple sites, including brain, left atrium of the heart and lung in a 6-year-old girl who was partially treated in the past at the age of 1.5 years; the patient had been event-free for four and a half years.

BACKGROUND: Crescentic glomerulonephritis is expressed pathologically by crescent formation in Bowman's capsule and clinically by rapidly progressive loss of renal function. The pathologic experience of crescentic glomerulonephritis in one institution was analyzed here. METHODS: We classified 25 cases of crescentic glomerulonephritis patients into 4 categories and reviewed the cases pathologically and clinically. RESULTS: We found no case with group I (anti- GBM disease), 8 cases in group II (immune complex glomerulonephritis) including 3 patients with IgA nephropathy, 2 patients with Henoch-Sch nlein purpura and 3 patients with APSGN, 12 cases in group III (ANCA-associated glomerulonephritis) including 7 patients with microscopic polyangitis, 4 patients with Wegener's granulmatosis and 1 patient with ANCA GN, and 5 cases in group IV (idiopathic crescentic glomerulonephritis). The mean ages of patients with group II, III, and IV were 32.0, 59.3 and 39.0 years old, respectively, and mean serum creatinine levels at the time of biopsy were measured as 9.1, 5.2, 8.8 mg/dL in each group. On light microscopic findings, the frequency of crescents in glomeruli was 64.4% in group II, 43.7% in group III, and 51.2% in group IV. The score of infiltration into tubules of inflammatory cells was 0.8 in group II, 0.4 in group III, and 0.6 in group IV and the score of fibrosis in interstitium was 1.0 in group II, 0.8 in group III and 1.2 in group IV. The score of atherosclerosis in arteries was 1.4, 0.9 and 1.6 in each group. CONCLUSION: We conclude that the precise diagnosis and classification of crescentic glomerulonephritis by an early renal biopsy and clinical assessments are important in the management of rapidly progressive (crescentic) glomerulonephritis. Since the number of the cases was not so enough, we could not analyze the statistical significance between morphologic differences of each group of crescentic glomerulonephritis, but if more cases were collected, acknowledgements of differences and prognostic factors in pathologic findings could be possible.

The overall incidence of malignancy in a renal transplanted patient is 3 to 5 times higher compared with general population. We report a very rare case of multiple leiomyoma originated from lung after renal transplantation. 33-year-old male underwent renal transplantation in November, 1989. A 5 mm sized pulmonary nodule was found in the left lower lobe incidentally in March, 2001. The size of pulmonary nodule increased and same lesion was found on the opposite side of the lung on chest roentgenogram after one year, so we proceeded with computed tomography of the chest. Variable sized multiple nodules in the whole lung field were noted, which were thought be metastatic lesions, and for detection of the primary site of malignancy, further study including esophagogastroduodenoscope, colon study, abdominal ultrasound, abdominal CT, bone scan and tumor marker were checked, but there was no evidence of primary cancer. After open lung biopsy low malignant potential smooth muscle tumor was noted, and Epstein-barr virus (EBV) DNA was detected. The patient had been maintained on immunosuppressive therapy with cyclosporine and mycophenolate mofetil (MMF), and after the diagnosis of leiomyoma administration of MMF was stoped, and cyclosporine dosage was reduced. With the reduction of immunosuppressants, intravenous immunoglobulin trial was done for the first cycle, but the efficacy of treatment is not clear.

BACKGROUND/AIMS: The aim of this study was to describe the types and causes of liver disease in patients from a single community hospital in Korea between April 2005 and May 2010. METHODS: A cohort of patients who visited the liver clinic of the hospital during the aforementioned time period were consecutively enrolled (n=6,307). Consistent diagnostic criteria for each liver disease were set by a single, experienced hepatologist, and the diagnosis of all of the enrolled patients was confirmed by retrospective review of their medical records. RESULTS: Among the 6,307 patients, 528 (8.4%) were classified as acute hepatitis, 3,957 (62.7%) as chronic hepatitis, 767 (12.2%) as liver cirrhosis, 509 (8.1%) as primary liver cancer, and 546 (8.7%) as a benign liver mass or other diseases. The etiologies in the acute hepatitis group in decreasing order of prevalence were hepatitis A (44.3%), toxic hepatitis (32.4%), other hepatitis viruses (13.8%), and cryptogenic hepatitis (9.1%). In the chronic hepatitis group, 51.2% of cases were attributed to viral hepatitis, 33.3% to nonalcoholic fatty liver disease, and 13.0% to alcoholic liver disease (ALD). Of the cirrhoses, 73.4% were attributable to viral causes and 18.1% to alcohol. Of the hepatocellular carcinoma cases, 86.6% were attributed to viral hepatitis and 11.6% to ALD. Among the benign tumors, hemangioma comprised 52.2% and cystic liver disease comprised 33.7%. CONCLUSIONS: Knowledge of the current status of the type and cause of liver disease in Korea may be valuable as a basis for evaluating changing trends in liver disease in that country.

Helicobacter pylori is a causative agent of type B gastritis and plays a central role in the pathogenesis of gastroduodenal ulcer and gastric cancer. To elucidate the host-parasite relationship of the H. pylori infection on the basis of molecular biology, we tried to evaluate the genomic diversity of H. pylori. An ordered overlapping bacterial artificial chromosome (BAC) library of a Korean isolate, H, pylori 51 was constructed to set up a genomic map. A circular physical map was constructed by aligning ApaI, Notl and SfiI-digested chromosomal DNA. When the physical map of H. pylori 51 was compared to that of unrelated strain, H. pylori 26695, completely different restriction patterns were shown. Fifteen known genes were mapped on the chromosome of H. pylori 51 and the genetic map was compared with those of strain 26695 and J99, of which the entire genomic sequences were reported. There were some variability in the gene location as well as gene order among three strains. For further analysis on the genomic diversity of H. pylori, when comparing the genomic structure of 150 H. pylori Korean isolates with one another, genomic macrodiversity of H. pylori was characterized by several features: whether or not susceptible to restriction digestion of the chromsome, variation in chromosomal restriction fingerprint and/or high frequency of gene rearrangement. We also examined the extent of allelic variation in nucleotide or deduced amino acid sequences at the individual gene level. fucT, cagA and vacA were confirmed to carry regions of high variation in nucleotide sequence among strains. The plasticity zone and strain-specific genes of H. pylori 51 were analyzed and compared with the former two genomic sequences. It should be noted that the H. pylori 51-specific sequences were dispersed on the chromosome, not congregated in the plasticity zone unlike J99- or 26695-specific genes, suggesting the high frequency of gene rearrangement in H. pylori genome. The genomc of H. pylori 51 shows differences in the overall genomic organization, gene order, and even in the nucleotide sequences among the H. pylori strains, which are far greater than the differences reported on the genomic. diversity of H. pylori.

Antineutrophilic cytoplasmic antibody (ANCA) associated vasculitis has been reported in Graves' disease patients treated with propylthiouracil (PTU). In most cases, it's renal involvements has been known as crescentic glomerulonephritis. A 41-year-old female patient with hyperthyroidism has been treated with PTU for 3 years. The patient had developed isolated hematuria and polyarthralgia with p-ANCA positivity, 6 months and 10 months after PTU treatment, respectively. She had been continuously treated with PTU until she was admitted at our hospital. Three months before admission, polyarthralgia was aggravated and purpura in both lower legs and hands was developed. Urinalysis revealed hematuria, proteinuria. Serologic evaluation showed p-ANCA positive. Skin biopy showed leukocytoclastic vasculitis and renal biopsy showed focal segmental glomerulosclerosis (FSGS). She was diagnosed as PTU-associated vasculitis with FSGS. Polyarthralgia and purpura were improved after discontinuing the PTU with prednisolone treatment but hematuria, proteinuria were not changed. We suggest that progression of PTU-associated focal segmental necrotizing glomerulonephritis to FSGS over two years might be due to continued PTU medication.
