Teratomas are neoplasm composed of a wide variety of tissues foreign to the organs or anatomic sites in which they arise. They generally arise in gonads but a few cases are described in extragonadal sites, such as sacro-coccygeal region, mediastinum, neck, and retroperitoneum. Most sacrococcygeal teratomas are encountered in infants, particularly in neonates, and a primary sacrococcygeal teratoma is a extremely rare neoplasm in adults. Recently, we experienced two cases of presacral teratomas arising in adult, therefore we present these cases with a brief review of the literatures

To evaluate the incidence and clinical course of AV conduction disturbances associated with acute myocardial infarction(MI) and coronary angiographic characteristics in acute inferior MI with AV blocks. We reviewed the medical records and serial ECG's in 89 patients with acute MI treated in CCU of Chonnam National University Hospital from january, 1987 through August, 1990. The subjects were 44 anterior MI's, 43 inferior MI's, and 2 anterior and inferior MI's. AV conduction disturbances were observed in 25.8% of all the patients with acute MI's, 48.8% of 43 inferior MI's and 4.5% of 44 anterior MI's. High degree AV block was observed in 20.0% of all the subjects, 39.3% of inferior MI patients, and none of anterior MI patients. The most severe AV blocks observed in each patients were 7(30.4%) first-degree, 5(21.7%) second-degree, and 11(47.8%) third-degree AV block. The initial AV conduction disturbances developed within 6 hours after onset of symptoms in 9(47.4%) and after 24-hours in 9(47.4%). Seven(30.4%) of 23 patients with AV block showed a transient progression in the degree of AV block, 5(29.4%) of 17 patients with first-or second-degree AV block progressed to third-degree AV block thereby constituting 45.5% of 11 third-degree AV blocks. Nine patients with early AV block less tended to progress in the degree of AV block than the patients with late AV block (1/9 vs 4.9). In early AV block the duration of high-degree AV block was shorter than late AV block(2.5 days vs 6.1 days). The duration of third-degree AV block was less than 2-hurs in 36.4~24 hours in 27.3%, and more than 24 hours in 36.4%. All third-degree AV blocks(90.9%) but one with the longest duration of 13 days returned to 1 : 1 AV conduction within 7 days. There was no significant difference in coronary angiographic findings including the incidence of stenotic lesion in proximal LAD and first septal perforator, number of involved vessel(s), and severity of RCA lesion between the patients with AV block and the patients without AV block in inferior MI.

BACKGROUND: Tuberculosis is still one of the most seriously threatening infections in Korea, because of multidrug resistant tuberculosis. Results of antituberculosis drug susceptibility test can provide clinicians very important informations for selection of proper regimens for treatment. METHODS: In this study the results of antituberculosis drug susceptibility test of 298 cases at Kyunghee Medical Center from 2000 to 2003 were retrospectively analysed to evaluate the trend of antituberculosis drug susceptibility. The procedure of drug susceptibility test was based on the absolute concentration method using Lowenstein-Jensen solid media. RESULTS: The resistance rate of Mycobacterium tuberculosis to one or more drugs was increased from 29.3% in 2000 to 48.2% in 2003, and the rates of multiple resistance to two or more drugs increased from 13.3% in 2000 to 20.5% in 2003. The increase in resistance rate to individual drug during study period were 20.0% to 24.1% in isoniazid, 9.3% to 19.3% in rifampicin, 5.3% to 15.7% in ethambutol, 4.0% to 10.8% in para-aminosalicylic acid, 2.7% to 6.0% in kanamycin, 1.3% to 7.2% in ethionamide, 1.3% to 6.0% in capreomycin, 1.3% to 7.2% in prothionamide, 0.0% to 12.1% in ofloxacin, 6.7%to 3.6% in streptomycin, 6.7% to 7.2% in cycloserine, 10.7% to 8.4% in pyrazinamide, respectively. CONCLUSIONS: The resistance rate of M. tuberculosis has been increased with years and multidrug resistant M. tuberculosis was commonly encountered in the specimens from the patients visited Kyunghee Medical center.

PURPOSE: In the past 30 years, the chemotherapeutic approach to advanced colorectal cancer has remained major challenge. Fluorinated pyrimidine has been the main active drugs, and cisplatin was introduced under clinical conditions. Because of the renal and hematologic toxicity of cisplatin, oxaliplatin was developed. The purpose of this study was to assess the clinical response to and the side effects of oxaliplatin chemotherapy. METHODS: From January 1999, 11 patients who received oxaliplatin chemotherapy entered this study. There were 9 males and 2 females, and their ages varied from 40 to 71 years old. The mean ECOG scale was 1. According to TNM staging, 2 was stage 2 at diagnosis, 5 at stage 3, and 4 at stage 4. Totally, we performed 57 cycles of oxaliplatin chemotherapy. Labaratory data and toxicity were assessed for each cycle according to the WHO scale. Ten (10) patients have received follow-up CT since treatment. RESULTS: Grade 1 anemia occurred in 68% of the cycles, grade 2 in 20%, and grade 3 in 12%. Grade 1 thrombocytopenia occurred in 35% of the cycles and grade 2 in 14%. Grade 1 leukopenia and neutropenia occurred in 27% and 25% of the cycles, respectively. Grade 1 stomatitis occurred in 12% of the cycles and grade 2 in 2%. Grade 1 nausea occurred in 44% of the cycles. Grade 1 vomiting occurred in 14% of the cycles and grade 2 in 4%. Grade 1 diarrhea occurred in 10% of the cycles and grade 2 in 4%. Nephrotoxicity was absent, and typical oxaliplatin neurotoxicity was reported as grade 1 in 2% of the cycles. No complete response was observed, and oxaliplatin che motherapy induced one partial remission. CONCLUSION: There was a mild hematologic and alimentary side effect. There were no renal and few neurologic side effects, but the response to oxaliplatin was poor.

We report here on a case of non-Hodgkin's lymphoma in which liver involvement was the predominant clinical manifestation. A healthy 44-year-old man presented with upper abdominal pain, hepatosplenomegaly, thrombocytopenia, elevated AST, ALT and bilirubin, and marked elevation of lactate dehydrogenase and alkaline phosphatase. The abdominal CT scan showed only diffuse hepatosplenomegaly and uneven contrast enhancement of the spleen without any definite mass of the liver and spleen. US-guided aspiration biopsy of liver and the histologic examination confirmed a diagnosis of non-Hodgkin's lymphoma, the diffuse large B cell type. Bone marrow biopsy showed the infiltration of malignant lymphoma cells. PET-CT showed an increased FDG uptake of the liver, spleen and long bones. The patient was treated with combination regimen of cyclophosphamide, doxorubicin, vincristine and prednisone chemotherapy. Even in the absence of a mass lesion or lymphadenopathy, primary hepatic or hepatosplenic lymphoma should be considered in differential diagnosis of hepatitis or liver cirrhosis, especially for patients with diffuse hepatosplenomegaly and markedly elevated LDH.

BACKGROUND: Interferon-gamma (IFN-gamma) is essential in the immune response to mycobacterial infections, and a complete or partial deficiency in the IFN-gamma receptor 1 (IFNgammaR1) or the IFN-gamma receptor 2 (IFNgammaR2) have been reported to confer susceptibility to a disseminated infection with nontuberculous mycobacteria. However, similar mutations in the IFN-gamma receptor have not been specifically examined in the patients with clinical tuberculosis. METHODS: This study searched for mutations in the IFN-gamma receptor gene that resulted in a partial IFN-gamma receptor deficiency in six patients with disseminated tuberculosis. The previously identified IFNgammaR1 and IFNgammaR2 coding regions were sequenced after amplification. RESULTS: There was no partial IFNgammaR1 deficiency including a homozygous recessive missense mutation causing an amino-acid substitution in the extracellular domain of the receptor (I87T) and a hotspot for small deletions (818delT, 818del4, 818insA) found in any of the patients. In addition, a partial IFNgammaR2 deficiency of the homozygous missense mutation (R114C) was not found in any of the patients. CONCLUSION: Genetic defects causing a partial IFN-gamma receptor deficiency were not identified in our patients with disseminated tuberculosis.
