PURPOSE: The purpose of this study was to describe the anglographic finding and clinical result of transarterial embolotherapy(TAE) in patients with injuries of renal artery branches by blunt trauma. MATERIALS AND METHODS: The study was based on retrospective analysis of seven cases, in which TAE was attempted for the control of traumatic renal arterial bleeding. All procedures were performed via the transfemoral approach. TAE was performed with stainless steel coil in two cases, Gelfoam in one case, and Gelfoam and stainless steel coil in four cases. RESULTS: Angiographic findings of vascular injuries were pseudoaneurysm in four cases, extravasation in two cases and arteriocalyceal fistula in one case. All procedures were performed successfully without complication. CONCLUSION: Pseudoaneurysm is a common anglographic finding in patients with injury of renal artery branches and TAE is considered a safe and effective method for treating such cases.

Distinct from migraine with aura or hemiplegic migraine, a rare clinical entity of migraine-like headache, transient focal neurologic deficit and CSF pleocytosis (HaNDL) has been known. Although the etiology or pathogenesis is unknown, possibility of viral infection or inflammation has been suggested. We report a 25-year-old man diagnosed as HaNDL with literature review.

PURPOSE: Brain metastasis is estimated to occur in 20~40% of solid tumor patients and the most common primary tumor is lung cancer. Even though the prognosis of brain metastasis is grave and the 1-year survival rate is only 15%, symptom palliations are made with whole brain radiation therapy. We retrospectively evaluated the clinical features and prognostic factors of lung cancer with brain metastasis. MATERIALS AND METHODS: From January 1987 to October 1999, 50 lung cancer patients with brain metastasis underwent whole brain radiation therapy. We reviewed the improvement in neurologic symptoms and survival according to the following parameters; performance status, histological type, presence of brain metastasis at the initial diagnosis of lung cancer, presence of extracranial metastasis, multiplicity of brain lesion, presence of primary lung symptom and treatment modalities. RESULTS: The most frequent symptom with brain metastasis was a headache (50%). Palliation of the headache and other symptoms was achieved in 81% of the patients. Median overall survival after brain metastasis was 21 weeks and the 1 year survival rate was 15%. Patients without extracranial metastasis had a longer median survival than those with, 38 weeks versus 15 weeks, respectively (p=0.01). CONCLUSION: In lung cancer with brain metastasis, neurologic symptoms can be palliated with whole brain radiation therapy, and in this study among such patients, absence of extracranial metastasis can be a good prognostic factor.

PURPOSE: Nonsteroidal anti-inflammatory drugs (NSAID) are well known to be associated with gastroduodenal ulcers. Also, small bowel ulceration sometimes develops. The authors reviewed their experiences to emphasize clinical importance of this disease entity. METHODS: A retrospective study was performed for patients who had undergone surgical intervention for lower gastrointestinal bleeding, small bowel perforation, or obstruction at Ewha Womans University Mok-Dong Hospital during a 5-year period. The cases related to acute trauma, postoperative obstruction, malignant ulceration, specific inflammatory bowel disease and other definite gastrointestinal lesions were excluded. The medical records were reviewed and the patients were interviewed. RESULTS: Out of total 110 cases, 4 patients had histories of NSAID use. They showed emergent presentations of acute abdomen, who were in debilitated or malnutrition states with underlying disease, without protective management for NSAID-use. They had all undergone surgical interventions because of small bowel ulcerations and its complications. CONCLUSION: NSAID induced small bowel ulcers should be a differential diagnosis of an acute abdomen or lower gastrointestinal bleeding of uncertain origin, especially for older age, and for patient with debilitating disease. Misuse or overuse of NSAID should be avoided to prevent ulcer complications, especially in high-risk patients.

Chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) are both lymphoproliferative disease occurring in different stages of B cell oncogeny. An increased incidence of secondary malignancies in patients with CLL is well recognized, however, the coexistence of both disorders in the same patient was very rare. Furthermore, clonal relationship between these diseases has not been clearly established. We report the occurrence of MM during the course of CLL. A 68-year-old patient was presented with general weakness and bone marrow aspiration showed a hypercellular marrow with 80% mature lymphocytes. At 5 months after diagnosis of CLL, bone marrow of the patient showed increased immature plasma cells. Serum protein electrophoresis showed monoclonal gammopathy and serum immunoelectrophoresis IgG kappa type monoclonality. The patient received six cycles of VAD (vincristine, adriamycin, dexamethasone) chemotherapy, but died of pneumonia and sepsis.

BACKGROUND: Angiogenesis plays a key role in the growth and metastasis of solid tumor. But it is not known whether the hematopoietic tumor depends on angiogenesis. To evaluate the prognostic roles of vascular endothelial growth factor (VEGF) expression and angiogenesis in patients with acute myelogenous leukemia, we analyzed the relationships between the level of VEGF expression, microvessel counts (MVC) in the bone marrow specimen of acute myelogenous leukemia patient and remission, relapse, and overall survival. METHODS: We evaluated bone marrow biopsy from 32 adult patients with newly diagnosed acute myelogenous leukemia and 16 controls with normal bone marrow. VEGF expression and MVC were assessed by immunohistochemical stain with monoclonal antibody to VEGF and polyclonal antibody to factor VIIIRAg, respectively. RESULTS: VEGF expression was higher in acute myelogenous leukemia than that of control (56.4+/-32.8% vs 19.0+/-25.9%, P=0.004). MVC was also higher in acute myelogenousleukemia than that of control (14.7+/-10.3 vs 6.2+/-3.8, P<0.001). Between high VEGF expression group and low VEGF expression group, there were no significant differences in the complete remission (CR), relapse and overall survival. There was no significant difference of MVC between CR group and non- CR group. Relapse group tends to have higher MVC than non-relapse group without statistical significance (P=0.06). There were no significant differences of MVC between hypervascular group and hypovascular group in remission, relapse and overall survival. CONCLUSION: In patients with acute myelogenous leukemia, VEGF expression and MVC were significantly higher than those of control. These findings suggest angiogenesis may play an important role in the pathogenesis of acute myelogenous leukemia. But there was no clinical correlation between the level of VEGF expression, MVC and remission, relapse and overall survival in this study. Further study willbe necessary for the establishment of prognostic role of VEGF expression and angioge-nesis and clinical efficacy of angiogenic inhibitors in acute myelogenous leukemia.

BACKGROUND: Philadephia chromosome negative chronic myeloproliferative disease (CMPD) is a clonal disorder which includes polycythemia vera (PV), essential thrombocythemia (ET) and idiopathic myelofibrosis (IMF). CMPD has chronic course and different clinical features with low rate of conversion to leukemia. We evaluated the clinical features of CMPD. METHODS: Since 1990, 57 cases of CMPD (18 PV, 35 ET and 4 IMF) were analysed and their clinical characteristics, survival and manner of evolution were evaluated retrospectively. RESULTS: Median age of 57 CMPD patients was 61 (range, 14~90) years and male to female ratio was 1:0.8. Most common clinical manifestations were dizziness/weakness (38.6%), headache (21.2%), cardiovascular events (19.3%) and other symptoms. Treatment with hydroxyurea was most frequent during clinical course of CMPD. Anagrelide was introduced in 12 patients recently. Complication of disease itself and treatment was not frequent except bleeding (3 cases) and thrombotic event (10 cases). Conversion to acute lekemia was none. Ten year overall survival was 83.3% in PV, 60.1% in ET and 4 cases of IMF were all alive at the 6 year follow up. CONCLUSION: CMPD is a chronic disease and long term control is much improved but definitive treatment without complication should be further investigated.

Although malignant pericardial effusion is a common complication of malignancy, chylopericardium is a rare entity characterized by the accumulation of chylous fluid in the pericardial sac. The lymphatic vessels of the pericardium drain into the thoracic duct. The mechanical obstruction of venous drainage plays an important role in the pathophysiology of this disease. In most cases, pericardiocenthesis is needed to prevent cardiac tamponade. We present a case of a 15-year-old boy diagnosed as non-Hodgkin's lymphoma, diffuse large B cell, with superior vena cava syndrome, who developed an isolated chylopericardium after the first cycle of chemotherapy. We confirmed the diagnosis with an echocardiography, lymphangiography, and fluid analysis. Chylopericardium was managed successfully with pericardiocenthesis and drainage. If pericardial effusion were developed during the treatment of non-Hodgkin's lymphoma, chylopericardium should be considered as one of the differential diagnoses and associated venous thrombosis around the thoracic duct outlet should be ruled out.

Riedel's thyroiditis (RT) is a rare chronic inflammatory disease of the thyroid gland. It is characterized by a fibroinflammatory process that partially destroys the gland and extends into adjacent neck structures. Its clinical manifestation can mask an accompanying thyroid neoplasm and can mimic invasive thyroid carcinoma. Therefore, diagnosis can be difficult prior to surgical removal of the thyroid, and histopathologic examination of the thyroid is necessary for a definite diagnosis. The concurrent presence of RT and other thyroid diseases has been reported. However, to our knowledge, the association of RT with acute suppurative thyroiditis and micropapillary carcinoma has not been reported. We report a rare case of concurrent RT, acute suppurative thyroiditis, and micropapillary carcinoma in a 48-year-old patient.
