BACKGROUND/AIMS: The disease course and factors associated with poor prognosis in Korean patients with Crohn’s disease (CD) have not been fully determined. The aim of this study was to explore potential associations between the clinical characteristics and long-term outcomes of CD and perianal fistulas in a Korean population. METHODS: The retrospective Crohn’s Disease Clinical Network and Cohort (CONNECT) study enrolled patients diagnosed with CD between July 1982 and December 2008 from 32 hospitals. Those followed for < 12 months were excluded. Clinical outcomes were CD-related surgery and complications, including nonperianal fistulas, strictures, and intra-abdominal abscesses. RESULTS: The mean follow-up period was 8.77 years (range, 1.0 to 25.8 years). A total of 1,193 CD patients were enrolled, of whom 465 (39.0%) experienced perianal fistulas. Perianal fistulizing CD was significantly associated with younger age, male gender, CD diagnosed at primary care clinics, and ileocolonic involvement. Both nonperianal fistulas (p=0.034) and intra-abdominal abscesses (p=0.020) were significantly more common in CD patients with perianal fistulas than in those without perianal fistulas. The rates of complicated strictures and CD-related surgery were similar between the groups. Independently associated factors of nonperianal fistulas were perianal fistulas (p=0.015), female gender (p=0.048), CD diagnosed at referral hospital (p=0.003), and upper gastrointestinal (UGI) involvement (p=0.001). Furthermore, perianal fistulas (p=0.048) and UGI involvement (p=0.012) were independently associated with the risk of intra-abdominal abscesses. CONCLUSIONS: Perianal fistulas predicted the development of nonperianal fistulas and intra-abdominal abscesses in Korean CD patients. Therefore, patients with perianal fistulizing CD should be carefully monitored for complicated fistulas or abscesses.

Intrathoracic metastasis of ovarian cancer has poor prognosis regardless of treatment modality. Recent development of surgical techniques and the new concept of direct infusion of chemotherapeutic agents with hyperthermia could help with the treatment of disseminated diseases in ovarian cancer. Using video-assisted thoracoscopic surgery and intracavitary chemotherapy with hyperthermia, we tried hyperthermic intrathoracic chemotherapy for a case of stage IV high-grade serous ovarian cancer with pleural metastasis. There was no high-grade complication related to the procedure. The patient is alive without disease at 32 months after initial treatment.

BACKGOUND: Recently it has been reported that several cytokine gene polymorphisms regulate cytokine production and play an important role in immune and inflammatory response. We evaluated IL-1beta IL-1Ra, and TNF-alpha gene polymorphism in patients with primary glomerulonephritis to determine the association between cytokine polymorphism and disease susceptibility. METHODS: In this study, we enrolled 118 patients with primary glomerulonephritis and healthy 300 persons who had visited the health screening center. We analyzed -511C/T polymorphism of IL-1beta tandem repeats polymorphism in intron 2 of IL-1Ra and -308G/A polymorphism of TNF-alpha We classified primary glomerulonephritis according to pathologic finding and clinical diagnosis. RESULTS: There were no differences with IL-1betaand TNF-alpha gene polymorphism between patient and control group. The carriage of IL1RN*2 was significantly associated with an increased risk of primary glomerulonephritis (patients:control=12.75:5.4%, p<0.01). IL1RN*2 was significantly frequent in patients with membranous GN or minimal change disease (p<0.05). When we classified glomerulonephritis according to clinical diagnosis, IL1RN*2 carriage rate was higher in patients with nephrotic syndrome and RPGN or acute nephritic syndrome than patients with asymptomatic urinary abnormalities (p<0.05). IL-1beta(TT) genotype was more prevalent in acute glomerulonephritis (68.4%) than asymptomatic urinary abnormalities or other glomerulonephritis. TNF2 carriage rate showed a lower tendency in patients with asymptomatic urinary abnormalities. CONCLUSION: IL1RN*2 is significantly associated with an increased risk of development of primary glomerulonephritis. We suggest cytokine gene polymorphism is also related to clinical manifestations of glumerulonephritis.

PURPOSE: To evaluate the effectiveness and safety of fentanyl-TTS in the management of radiotherapy induced acute pain and cancer pain treated with radiotherapy. MATERIALS AND METHODS: Our study was open labelled prospective phase IV multi-center study. the study population included patients with more 4 numeric rating scale(NRS) score pain although managed with other analgesics or more than 6 NRS score pain without analgesics. Patients divided into two groups; patients with radiotherapy induced pain (Group A) and patients with cancer pain treated with radiotherapy (Group B). All patients received 25 ug/hr of fentanyl transdermal patch. Primary end point was pain relief; second end points were change in patient quality of life, a degree of satisfaction for patients and clinician, side effects. RESULTS: Between March 2005 and June 2005, 312 patients from 26 participating institutes were registered, but 249 patients completed this study. Total number of patients in each group was 185 in Group A, 64 in Group B. Mean age was 60 years and male to female ratio was 76:24. Severe pain NRS score at 2 weeks after the application of fentanyl was decreased from 7.03 to 4.01, p=0.003. There was a significant improvement in insomnia, social functioning, and quality of life. A degree of satisfaction for patients and clinician was very high. The most common reasons of patients' satisfactions was good pain control. Ninety six patients reported side effect. Nausea was the most common side effect. There was no serious side effect. CONCLUSION: Fentanyl-TTS was effective in both relieving pain with good tolerability and improving the quality of life for patients with radiotherapy induced acute pain and cancer pain treated with radiotherapy. The satisfaction of the patients and doctors was good. There was no major side effect.

OBJECTIVES: We investigated the association of SNP A and P1763 polymorphisms on dystrobrevin binding protein 1(DTNBP1) gene with smooth pursuit eye movement(SPEM) abnormality in Korean schizophrenic patients. METHODS: We measured SPEM function in 217 Korean schizophrenics(male 116, female 101) and divided them into two groups, one is a good SPEM function group and the other is a poor SPEM function group. We then analyzed SNP A polymorphism and P1763 polymorphism on DTNBP1 gene from their DNAs extracted from their blood. We compared the differences of genotype and allele distributions of the two polymorphisms on DTNBP1 gene between the two groups. RESULTS: The Ln S/N ratio(mean+/-SD) of the good SPEM function group was 4.39+/-0.33 and the ratio of poor SPEM function group was 3.17+/-0.71. There were no statistically significant differences of age and male/female ratio between the two groups. There were no significant differences of genotype or allele distributions of the SNP A polymorphism and P1763 polymorphism on DTNBP1 gene between the two schizophrenic groups divided by SPEM function. CONCLUSION: The results suggest that SNP A polymorphism and P1763 polymorphism on DTNBP1 gene might not be related to SPEM function abnormality in schizophrenia.

OBJECTIVE: The aim of this study was to investigate the gene expression profiles using GeneFishing(TM) DEG kit in Korean women with cervical squamous cell carcinoma. METHODS: Cervical cancer biopsies were obtained from patients at the Department of Obstetrics and Gynecology, St. Mary's hodpital. In this study, we used a common reference that was mixed with an equal amount of RNA extracted from non-cervical cancer patients. The profiles of expression genes between cervical normal and squamous cell carcinoma tissue were identified using GeneFishing(TM) DEG Kit and screened by BLAST search. RESULTS: Almost 100 differential expressed genes were identified in universal control and cervical squamous cell carcinoma, 53 of differential expressed genes, up-regulated expression of 32 and 21 down-regulated expression was sequenced. Up-regulated genes were calcylin, calgranulin A, TRK oncogene, HLC5, fibrillarin, collagene type I alpha1 etc. and down-regulated genes were galectin 1, PRP8 pre-mRNA precessing factor 8 homology, clusterin etc. CONCLUSION: We identified gene expression profile in cervical squamous cell carcinoma using GeneFishing(TM) Kit in Korean women. The functional genomics of these genes should be further studied.

BACKGROUND: The pathogenic human parvovirus B19 is the etiologic agent of erythema infectiosum and causes other events including aplastic crisis,hydrops fetalis and fetal loss.Recently,it has been reported in many articles that human parvovirus B19 infection is associated with rheumatoid arthritis (RA).In contrast to these reports from the United Kingdom,Germany,Japan and China,different results were reported that there is no association between human parvovirus B19 and the pathogenesis of RA in Northern Ireland,Finland and France.This study aimed to investigate the association between human parvovirus B19 and RA in Korea. METHODS: Sera from 104 patients with RA,40 with osteoarthritis (OA)and 32 with systemic lupus erythematosus (SLE)were tested for IgG and IgM of human parvovirus B19 by ELISA (Biotrin),respectively. RESULTS: There were no statistical differences among RA,OA and SLE patients in both anti-human parvovirus B19 IgG and IgM (p>0.05).Human parvovirus B19 IgM was positive in only four RA patients and negative in all SLE and OA patients. CONCLUSION: Human parvovirus B19 infection showed no association with RA in Korea,which is different from reports from other countries,especially Japan and China which are our neighbors.We thought that this result was due to the ethnic or national differences of baseline titer of anti-human parvovirus B19.Therefore anti-human parvovirus B19 test for RA patients is not necessary in Korea.In conclusion,we suggest that the indication and interpretation of anti-human parvovirus B19 testing in RA patients should be applied differently for each nation.

BACKGROUND: The pathogenic human parvovirus B19 replicates only in erythroid progenitor cells. The blood-group P antigen has been reported to be the cellular receptor of this virus. Human parvovirus B19 is known to be the etiologic agent of erythema infectiosum and causes a chronic anemia resulting from a persistent infection in immunocompromised patients. Recently, it has been re-ported to play a role in rheumatoid arthritis activity (RA). This study was aimed to determine whether human parvovirus B19 has a role to play in chronic anemia of RA which is the case in immunocompromised patients. We also investigated the association between the activity of the disease in RA and human parvovirus B19 infections. METHODS: Of 107 patients that had RA, 49 patients had anemia and 58 patients did not. We used ESR and CRP results to estimate the degree of disease activity. Thirty-eight patients having RA had a normal ESR and 69 patients had a high ESR. Sixty patients had normal CRP and 47 patients had high CRP. Sera of patients were tested for the presence of anti-human parvovirus B19 (IgG and IgM) using ELISA (Biotrin, Co. Dublin, Ireland). RESULTS: Of 107 patients who had RA, 79.4% (85/107) and 3.7% (4/107) were positive for IgG and IgM, respectively. There were no statistical differences between RA patients with anemia and those without anemia in the anti-human parvovirus B19 test (P>0.05). There were also no statistical differences between patients that had a normal or high ESR/CRP ratio (P>0.05). CONCLUSIONS: Human parvovirus B19 did not play a role in the formation of the chronic anemia of RA which is different from the cases of immunocompromised patients. Furthermore, we found no association between disease activity in RA and human parvovirus B19 infections.

Chronic granulomatous disease(CGD) is a genetically inherited disorder caused by the failure of phagocytic cells to produce superoxide. It is characterized by frequent and uncontrollable infection which often lead to death in early childhood. The first clinical signs may be confined to skin and manifest themselves as abscesses, pyoderma, eczema or draining sinuses. The disease was first reported in 1957 and thereafter the biomolecular mechanism has been found. The first report in Korea was an autopsy case in 1979 and since then there have been a few case reports. This disease is diagnosed by symptoms, such as high fever, cervical lymphadenopathy, skin nodule, lung field infiltration, periumbilical abscess, liver abscess, pyoderma and pericordal abscess. The pathogen here were catalase producing bacteria and fungi. However, we have experienced a case of CGD, in which symptoms were perianal, scrotal abscesses and lung field nodular infiltration. In this case the pathogen was found as a catalase negative Enterococcus. (J Korean Pediatr Soc 2000;43-846-850)

BACKGROUND: Antimicrobial susceptibility testing of Helicobacter pylori(H. pylori) is not yet standardized but broth dilution or agar dilution are considered as standard methods. In the broth microdilution method, antibiotic dilutions of different concentrations are made each time, but most of it is discarded because only small volumes of dilutions are used. To improve this tedious procedure and the waste of reagents, antibiotic solutions in 96-well microplates were frozen at -20 degrees C to evaluate their useful storage periods. METHODS: Various concentrations of metronidazole(MTZ) and clarithromycin(CLR) solutions were divided into ten plates of 96-well microplates, sealed and stored at -20 degrees C. The broth microdilution susceptibility test was done with fresh and preserved antibiotic dilutions each month on 5 occasions for 4 strains(initial minimum inhibitory concentration(MIC) for MTZ 1, 4, 16, 64 ug/mL, initial MIC for CLR <0.125, <0.125, <0.125, 32 ug/mL) of H. pylori. The difference of MIC values of more than +/-2 log2 diluti on was considered significant. RESULTS: For both MTZ and CLR, the difference of MIC values of fresh and frozen antibiotic solutions was within +/-1 log2 dilution and the results of susceptibility test were the same for 7 months. CONCLUSIONS: Various concentrations of frozen MTZ and CLR solutions could be used for at least 7 months for the antimicrobial susceptibility testing of H. pylori.
