Although tumor necrosis factor (TNF)-alpha antagonist is a successful treatment modality for various autoimmune diseases, including rheumatoid arthritis (RA), ankylosing spondylitis and psoriatic arthritis, many adverse effects have been reported. Cutaneous adverse reactions of TNF-alpha antagonist include skin rash, urticaria, lupus like rash, seborrheic dermatitis and different kinds of psoriasiform dermatitis. We report a case of psoriasiform dermatitis during TNF-alpha antagonist treatment in a 50-year-old woman with RA. The patient has been treated with adalimumab. After 2 months, she developed pruritic erythematous eruption and desquamative lesions on the head and limbs, which were defined as psoriasiform change by a skin biopsy. These skin lesions are successfully treated with combination therapy, including cessation of adalimumab, corticosteroid and phototherapy.

Systemic sclerosis (SSc) is characterized by the presence of microvascular disease and various patterns of cutaneous and parenchymal fibrosis. Manifestation of SSc may occur in numerous tissues and organs and can be particularly problematic when present in the lungs, kidneys or heart. Cardiac involvement in SSc includes pericarditis, myocardial disease, conduction abnormalities, and arrhythmia. Sick sinus syndrome is described as a combination of symptoms (dizziness, confusion, fatigue, syncope and congestive heart failure) caused by sinus node dysfunction and manifested by marked sinus bradycardia, sinoatrial block, or sinus arrest. Sinus node dysfunction is most often seen in the elderly but also, rarely, in systemic amyloidosis and connective tissue disease. Sick sinus syndrome is rarely found in patients with SSc, of which there has been only one case report, according to a review of the literature. Therefore, we report a case of sick sinus syndrome in a 71-year-old female with SSc.

BACKGROUND: Diamond Blackfan anemia (DBA), characterized by impaired red cell production, is a rare condition that is usually symptomatic in early infancy. The purpose of this study was to assess nationwide experiences of DBA encountered over a period of 20 years. METHODS: The medical records of 56 patients diagnosed with DBA were retrospectively reviewed from November 1984 to July 2010. Fifteen institutions, including 13 university hospitals, participated in this study. RESULTS: The male-to-female ratio of patients with DBA was 1.67:1. The median age of diagnosis was 4 months, and 74.1% were diagnosed before 1 year of age. From 2000 to 2009, annual incidence was 6.6 cases per million. Excluding growth retardation, 38.2% showed congenital defects: thumb deformities, ptosis, coarctation of aorta, ventricular septal defect, strabismus, etc. The mean hemoglobin concentration was 5.1+/-1.9 g/dL, mean corpuscular volume was 93.4+/-11.6 fL, and mean number of reticulocytes was 19,700/mm3. The mean cellularity of bone marrow was 75%, with myeloid:erythroid ratio of 20.4:1. After remission, 48.9% of patients did not need further steroids. Five patients with DBA who received hematopoietic transplantation have survived. Cancer developed in 2 cases (3.6%). CONCLUSION: The incidence of DBA is similar to data already published, but our study had a male predilection. Although all patients responded to initial treatment with steroids, about half needed further steroids after remission. It is necessary to collect further data, including information regarding management pathways, from nationwide DBA registries, along with data on molecular analyses.

Background/Aims: We examined the efficacy and safety of tegoprazan as a part of first-line triple therapy for Helicobacter pylori eradication. Methods: A randomized, double-blind, controlled, multicenter study was performed to evaluate whether tegoprazan (50 mg)-based triple therapy (TPZ) was noninferior to lansoprazole (30 mg)-based triple therapy (LPZ) (with amoxicillin 1 g and clarithromycin 500 mg; all administered twice daily for 7 days) for treating H. pylori. The primary endpoint was the H. pylori eradication rate. Subgroup analyses were performed according to the cytochrome P450 (CYP) 2C19 genotype, the minimum inhibitory concentration (MIC) of amoxicillin and clarithromycin, and underlying gastric diseases. Results: In total, 350 H. pylori-positive patients were randomly allocated to the TPZ or LPZ group. The H. pylori eradication rates in the TPZ and LPZ groups were 62.86% (110/175) and 60.57% (106/175) in an intention-to-treat analysis and 69.33% (104/150) and 67.33% (101/150) in a per-protocol analysis (non-inferiority test, p=0.009 and p=0.013), respectively. Subgroup analyses according to MICs or CYP2C19 did not show remarkable differences in eradication rate. Both first-line triple therapies were well-tolerated with no notable differences. Conclusions TPZ is as effective as proton pump inhibitor-based triple therapy and is as safe as first-line H. pylori eradication therapy but does not overcome the clarithromycin resistance of H. pylori in Korea

PURPOSE: Wilms tumor is the most common malignant renal tumor in children. We investigated the epidemiology, clinical features and treatment outcome of the children with Wilms tumor in Korea during the recent 10 years. METHODS: Two hundred forty six patients were enrolled between January 1991 and December 2000 from 26 major hospitals in Korea. The data regarding the clinical features including sex, age, pathologic type, prognostic factor and treatment outcome of patients were analyzed retrospectively by review of patient's medical records. Kaplan-Meier survival curves were constructed, The differences between groups were analyzed by log-rank test. RESULTS: There were 130 males and 116 females. The incidence between the age of 1~4 years was the highest with 66.2%. The annual incidence rate per 1, 000, 000 population varied from 1.9 to 2.1. The 10 years overall survival rate according to sex, clinical stage, pathologic type and relapse were as follows: 88.6% in male, 90.9% in female, 100% in stage I, 94.7% in stage II, 92.1% in stage III, 63.4% in stage IV, 85.7% in stage V, 95.3% in favorable histology, 64.1% in unfavorable histology, 94.8% in non-relapse, and 40.9% in relapse. The relapse rate was 12%. The 10 years overall survival rate of 246 patients were 89.1%. CONCLUSION: Our results could provide the most recent and important clinical information on Wilms tumor of children in Korea.

PURPOSE: Malignant lymphoma is the primary malignant tumor derived from lymphoid organs. It is composed of Hodgkin's disease and non-Hodgkin lymphoma. Recently, survival rate is on the rise due to improved combination chemotherapy, radiotherapy and high dose chemotherapy followed by hematopoietic stem cell transplantation. In South Korea, no epidemiologic studies concerning malignant lymphoma in the pediatric age group has been performed. Therefore, the Korean Society of Pediatric Hematology-Oncology retrospectively analyzed the incidence, pathologic subtypes, treatment strategies, and survival rates of pediatric malignant lymphomas in South Korea. METHOD: Questionnaires were made and sent to a group of training hospitals, with a return of 580 questionnaires from 24 hospitals. Among them, 517 reports were suitable for analysis. RESULTS: Among the 517 cases, Hodgkin's disease accounted for 58 cases and non-Hodgkin's lymphoma for 459 cases. Male to female ratio for malignant lymphoma was 2.7. Mean age at diagnosis was 8.3 years. Among the pathologic subtypes, mixed cellularity was the most frequent subtype for Hodgkin's disease. Most (70.7%) cases of non-Hodgkins lymphoma belonged to high grade NHL. Burkitt lymphoma accounted for 102 cases, and lymphoblastic lymphoma was found in 58 cases. Peripheral lymphadenopathy was the most common presenting sign upon diagnosis. B symptoms were significantly more frequent in Hodgkin's disease patients than in non-Hodgkin lymphoma patients. The Complete response rate was 62.1% for non-Hodgkin's lymphoma, and 82.8% for Hodgkin's disease. Overall 5 year survival rate was 60.0% in non-hodgkin's lymphoma, and 84.8% in Hodgkin's disease. CONCLUSION: The annual incidence of malignant lymphoma in Korea is 4.7 per million. In cases of chemotherapy-sensitive, refractory or relapsed malinant lymphoma, high dose chemotherapy followed by hematopoietic stem cell transplantation is vital for improved survival. For more systematic analysis of epidemiology on malignant lymphomas, better surveillance mechanisms on the occurrence of malignant lymphomas are crucial, and establishment of standardized treatment protocol for malignant lymphoma is required.

PURPOSE: The annual incidence of aplastic anemia (AA) in Asian countries is higher than in Western countries. The pathogenesis in AA has been investigated in hematopoiesis and immunology. Recently, the survival rate and the quality of life of the patients with AA have been steadily improved by the development of a variety of treatments such as the immunosuppressive therapy (IST), and hematopoietic stem cell transplantation (HSCT). The Korean Society of Pediatric Hematology-oncology retrospectively investigated the incidence, treatment strategies, survival rate, and time to become independent from transfusion in patients with AA, who were diagnosed from January 1st, 1991 to December 31st, 2000 in Korea. METHODS: All the questionnaires were sent to a group of training hospitals, and we collected about 600 questionnaire forms from 27 hospitals. However, 493 reports were available for data analysis. RESULTS: The male and female ratio in AA is 1.1 (259 males vs. 234 female). The median age at diagnosis is 9 years old (range; 0.8~16 years old). The annual incidence of children with AA in Korea is 4.5 per million on the basis of Korean pediatric population. In etiology, there are 20 cases (4.1%) in congenital and others in acquired AA. In acquired AA, the cause of illness was not identifiable for most of the patients, but 1 patient had hepatitis-associated AA, and 3 patients developed the illness after medication. According to the initial laboratory data at diagnosis, the peripheral blood findings showed that hemoglobin is 7.1+/-2.4 g/dL, white blood cell 3, 200/microL (200~16, 550), absolute neutrophil counts 670/microL (0~12, 487), platelets 19, 000/microL (1, 000~500, 000), and corrected reticulocytes 0.18% (0.0~4.7). The bone marrow examination revealed that cellularity was below 25% in 348 patients, and over 25% in 105 patients. In the available data, 269 patients (54.6%) were diagnosed of severe aplastic anemia (SAA) and 224 patients of non-SAA (NSAA). HSCT were done for 96 patients (19.5%) and others received another treatments such as the IST. The anti-thymocyte globulin (ATG) or anti-lymphocyte globulin (ALG) treatment was done for 263 cases, corticosteroids for 259, cyclosporine A (CSA) for 215, and anabolic steroids for 138. The combination IST including ATG or ALG plus corticosteroid plus CSA were applied to 154 children with AA, and transfusion only in 37, as conservative care. In case of those patients with HSCT, the time from diagnosis to transplantation was 12 months (1~144 months) and the sources of stem cells were bone marrow in 82 cases, growth factor mobilized peripheral blood in five, and cord blood in six. There were 57 patients transfused below 40 units of blood products before HSC transplantation. Graft rejection was identified from 16 patients, and booster transplantations were done for 12 patients among them. In complications of HSCT, the graft versus host disease was developed in 20 patients and viral diseases in 12 cases including the CMV, herpetic infection, and hepatitis. Also, one patient suffered from veno-occlusive disease. The overall survival rate in children with AA is 64.3%. The survival rate in HSCT is better than that IST (76.9% vs. 62.6%, P< 0.05). In IST, overall survival rate in very SAA showed lower than SAA and NSAA, and in SAA lower than NSAA in case of absolute neutrophil count below 200/microL (P< 0.05). There was no significant difference in terms of the sex, age at beginning of treatment. In HSCT, transfusion was not related to the survival rate. However, overall survival rate is better in short interval between diagnosis and HSCT than in long interval (P< 0.05). There was no significant difference in the probability of transfusion independence according to treatment strategies, even though it was 71.0% in HSCT and 12.8% in immunosuppressive therapy at the end point of survey (P=0.47). The response pattern was as follows. There were 155 cases of complete response, 110 of partial response and 120 of no response in spite of various treatments. The relapse after treatment was found in 11 patients after IST, of which 6 patients experienced more than 2nd relapse. The median time between the end of treatment and relapse was 16 months (6~84 months). Only three cases developed into other diseases (1 case into acute myeloid leukemia and 2 cases into myelodysplastic syndrome). The median time from diagnosis to the end of treatment was 62 months (0.5~174 months). In fatal cases, the median time between diagnosis and death was 29 months (0~144 months) despite several therapeutic strategies. CONCLUSION: In Korea, the annual incidence of children with AA is 4.5 per million. This result is similar to the ones reported in other Asian countries, but higher than those in Western countries. Although a lot of children with AA received various therapies including IST or HSCT, new treatment strategies have to be developed to improve the survival rate and the quality of life of children with AA

BACKGROUND/AIMS: Despite of increasing numbers of reports on intraductal papillary mucinous tumor (IPMT), there is still difficulty in its' diagnosis, treatment and prediction of prognosis. The purpose of this multicenter study was to evaluate the clinico-pathological features of IPMT in Korea and suggest the prediction criteria of malignancy in IPMT. METHODS: We retrospectively reviewed the clinico-pathological data of 208 patients who underwent operations with IPMT between 1993 and 2002 at 28 institutes in Korea. RESULTS: Of the 208 patients with a mean age of 60.5+/-9.7 years, 147 were men and 61 were women. 124 patients underwent pancreatoduodenectomy, 42 distal pancreatectomy, 17 total pancreatectomy, 25 limited pancreas resection. Benign cases were 128 (adenoma (n=62), borderline (n=66)) and malignant cases were 80 (non-invasive (n=29), invasive (n=51)). A significant difference in 5-year survival was observed between benign and malignant group (92.6% vs. 65.3%; p=0.006). Of the 6 factors (age, location, duct dilatation, tumor appearance, main duct type, and tumor size) that showed the statistical difference in univariate analysis between benign and malignant group, we found three significant factors (tumor appearance (p=0.009), tumor size (p=0.023), and dilated duct size (p=0.010)) by multivariate analysis. CONCLUSION: Although overall prognosis of IPMT is superior to ordinary pancreatic cancer, more curative surgery is recommended in malignant IPMT. Tumor appearance (papillary), tumor size (> or =30 mm) and dilated duct size (> or = 12 mm) can be used as preoperative indicators of malig-nancy in IPMT.
