Medullary thyroid carcinoma accounts for 3% of all thyroid gland malignancies. It commonly metastasizes to liver, lung, and bone. It rarely metastasizes to skin, and only a few such cases have been documented. Cutaneous metastasis suggests a poor prognosis, with a mean survival of 7.5-19 months. The most effective treatment for skin metastasis is complete surgical removal of all local and regional lesions. The response to systemic chemotherapy is typically poor. We report a case of medullary thyroid carcinoma with cutaneous metastases, which responded to chemotherapy.

Coronary artery embolization is an extremely rare and potentially lethal complication of atrial myxomas. We observed of a case of left atrial myxoma associated with acute anteroseptal and inferior myocardial infarction. A transthoracic echocardiographic study revealed the presence of an echogenic, mobile mass, compatible with myxoma in the left atrium. Coronary angiography disclosed abrupt occlusions of the distal left anterior descending artery and the right coronary artery. The tumor was successfully removed surgically after medical treatment and the patient was doing well post operatively at 6-month follow-up.

Field efficacy of enterotoxigenic Escherichia coli-specific phage (PhiCJ19) as a feed additive was evaluated in weaning piglets. Fifty-four piglets at 3~4 weeks old were allocated in three different groups and two of them were fed with bacteriophage at different concentrations (10(6) PFU/kg feed and 10(8) PFU/kg feed, respectively) for 30 days. Body weight and feed intake were measured at 10 days interval and body condition and fecal score were inspected every day. Based on the measurement, feed conversion rate (FCR) and average daily gain (ADG) of each group during 30 days were analyzed. The analysis suggests that the bacteriophage may help the improvement of FCR and ADG at 10(8) PFU/kg of bacteriophage feeding group in 30 days. A result from analysis of fecal score indicates that the bacteriophage also may help to relieve the intermittent diarrhea in post-weaning stage. Those results suggest that bacteriophage might help the growth of piglets in post-weaning stage.

Coombs' negative autoimmune hemolytic anemia (AIHA) is a rare disease which shares similar clinical and hematological features with Coombs' positive AIHA, but its exact frequency remains unknown. There have been few reports of idiopathic thrombocytopenic purpura (ITP) and Coombs' negative AIHA associated with other lymphoproliferative disorders (LPDs). Since there is a well known association between LPDs and autoimmune phenomena, it is important to investigate the possibility of an underlying malignancy. We report a case of ITP and Coombs' negative AIHA associated with diffuse large B-cell lymphoma.

Asymptomatic intrahepatic early-stage bile duct carcinoma without jaundice is difficult to diagnose because it does not have any characteristic clinical signs and symptoms. The clinical implication of early-stage intrahepatic ductal cholangiocarcinoma is great, because it allows curative resection and excellent long-term survival. Recently we experienced early-stage intrahepatic cholangiocarcinoma which was incidentally detected by a clue of elevated serum alkaline phosphatase and gamma-GT without jaundice and any symptoms. Abdominal US showed focal intrahepatic bile duct dilatation. ERCP could not demonstrate the lesion, while MRCP revealed the obstructed duct (S6) with proximal dilatation. For evaluation of a focal intrahepatic stricture, PTCS examination and biopsy were done. With the help of MRCP and PTCS, the lesion was diagnosed as papillary adenocarcinoma preoperatively. The patient was underwent right liver lobectomy and confirmed early-stage intrahepatic ductal adenocarcinoma and she is well-being without cancer recurrence for a follow-up period of 1 year.

We report the case of a 43-year-old woman with Cushing's syndrome showing bilateral adrenococortical adenomas. We performed bilateral selective adrenal vein samplings. Hypersecretion of cortisol on the left sided adrenal tumor was observed, but no evidence of cortisol hypersecretion from the adrenal tumor on the right side was observed. The left adrenal tumor was resected selectively, but the right adrenal gland was reserved. The left adrenal tumor was histologically diagnosed as a adrenal adenoma without any evidence of nodular hyperplasia. Following the resection of the left adrenal gland, no cortisol hypersecretion from the remaining adrenal tumor on the right side was observed until now, suggesting that a selective adrenalectomy of functioning adenoma may be an acceptable treatment modality.

PURPOSE: This study tried to identify novel gastric autoimmune antigens that might be involved in aggravating the atrophic gastritis among patients with Helicobacter pylori infection using two-dimensional immunoblotting analysis. MATERIALS AND METHODS: Proteins from gastric mucosal antrectomy specimens and AGS cells (gastric adenocarcinoma cell lines derived from a Caucasian patient who had received no prior therapy) were 2-dimensionally immunoblotted separately with a pool of 300 sera from H. pylroi-infected patients at Gyeongsang National University Hospital. RESULTS: Thirty-eight autoantigenic proteins including alcohol dehydrogenase [NADP+], alpha enolase, gastrokine-1, gastric triacylglycerol lipase, heat shock 70 kDa protein 1, and peroxiredoxin-2 were identified in the gastric mucosal tissue. Fourteen autoantigenic proteins including programmed cell death 6-interacting protein, serum albumin and T-complex protein 1 subunit gamma were identified in the AGS cells. Albumin, alpha-enolase, annexin A3, cytoplasmic actin 1, heat shock cognate 71 kDa protein and leukocyte elastase inhibitor were commonly observed autoantigenic proteins in both gastric mucosal tissue and AGS cells. Alpha-enolase, glutathione S-transferase P, heat shock cognate 71 kDa protein, heat shock 70 kDa protein 1, human mitochondrial adenosine triphosphate synthase (ATP) subunit beta, mitochondrial 60 kDa heat shock protein, peroxiredoxin-2, 78 kDa glucose-regulated protein precursor, tyrosine-protein phosphatase non-receptor type 11 and Tryptophan-Aspartic acid (WD) repeat-containing protein 1 showed 60% or higher amino acid positivity. CONCLUSION: These newly identified gastric autoimmune antigens might be useful in the control and prevention of gastroduodenal disorders, and might be valuable in breaking the vicious circle that exists in gastroduodenal disorders if their pathophysiological roles could be understood in the progress of chronic atrophic gastritis, gastroduodenal ulcers, intestinal metaplasia, and gastric carcinogenesis.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is one of the most important armamentarium against various hematologic malignancies or some solid tumors. We investigated the number of patients who might need transplants and compared with that of actual transplants to conceptualize current status and circumstances of HSCTs in Korean children. METHODS: Questionnaires were sent to Korean Society of Hematopoietic Stem Cell Transplantation (KSHSCT) members who were taking care of children with malignancies or hematologic diseases. Almost all of the newly diagnosed patients between Jan, 1st and Dec, 31st, 2003 were enrolled in the study. RESULTS: Seven hundred forty eight children (male to female ratio = 1.4:1) were enrolled. The median age was 6.1 years old (8 days~28.8 years old). Malignant diseases consisted of 695 cases (92.9%), and among them almost half were hematologic malignancies. The participating members speculated that HSCTs should be indicated in 285 children (38.1%) which included 209 allogeneic, and 76 autologous transplants. In reality, however, allogeneic HSCTs were performed only in 140 children (67.0%) with the median interval of 5.9 month, and autologous transplants in 44 children (57.9%) with 8.3 month. In autologous setting, all the patients received peripheral blood stem cells (PBSCs), whereas bone marrow (61%), cord blood (34%), and PBSC (5%) were used in allogeneic HSCTs. Donor types were as follows: unrelated donor (37%), cord blood (34%), sibling donor (25%), and family (4%). The reasons for not performing HSCTs were unfavorable disease status or death, no availability of suitable donor, economical situation, and refusal by parental preferences. Under the strict insurance regulations, many transplants were not covered by insurance. More autologous transplants were performed without insurance coverage than allogeneic HSCTs (P=0.013). Those cases were advanced cases and HLA mismatch transplants for allogeneic setting, and relatively rare diseases still awaiting favorable results of transplants for autologous setting. CONCLUSION: HSCTs are essential part of treatment strategies for children with various diseases. Unfortunately, however, a third of patients who were in need of transplants did not receive HSCTs due to various reasons. It is necessary to expand unrelated donor pool or cord blood banks for the cases lacking HLA-identical sibling donors. Also medical insurances should cover HSCTs for rare diseases as well as for less favorable but novel situations where there are no suitable alternatives.

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.
