To validate ventricular diastolic phase parameters of reconstructed transmitral flow rate curve by M-mode, 2-dimensional and pulsed Doppler Echocardiography, these parameters were compared with same parameters by left ventriculography. The study population was 22 patients who received both coronary arteriography and echocardiographic examination. Transmitral flow rate curve and left ventricular filling volume curve were reconstructed from transmitral flow velocity curve by pulsed Doppler, mitral annulus diameter by two diameter by two dimensional and diastolic motion of both mitral leafltes by M-mode echocardiography. From left ventriculography, left ventricular filling volume curve and transmitral flow rate curve were made using area-length method by Sandler and Dodge. From trasmitral flow fraction, 1/2 diastolic time filling fraction, normalized peak filling volume, 1/3 diastolic time filling fraction, 1/2 diastolic time fraction, normalized peak early filling rate and ratio of early to late peak filling rate were measured. Correlation between same parameters derived from echocardiography and left ventriculography were observed. 1) Total diastolic filling volume:correlation coefficient r=0.47, P<0.05. 2) 1/3 diastolic time filling fraction:correlation coefficient r=0.90, P<0.001. 3) 1/2 diastolic time filling fraction:correlation coefficient r=0.80, P<0.001. 4) Normalized peak early filling rate:correlation coefficient r=0.57, P<0.01. 5) Ratio of early to late peak filling rate:correlation coefficient r=0.85, P<0.001. Therefore, left ventricular diastolic phase parameters of reconstructed transmitral flow rate curve using, M-mode, 2-dimensional and pulsed Doppler echocardiography seems to be useful for the noninvasive evaluation of the left ventricular diastolic function.

Primary mucosa-associated with a lymphoid tissue (MALT) lymphoma is a rare distinct subtype of non-Hodgkin’s lymphoma that occurs in approximately 8% of all non-Hodgkin lymphomas. Primary gastrointestinal MALT lymphoma usually occurs in the stomach, but duodenal involvement is extremely rare. Therefore, the clinical manifestations, treatment, and prognosis of primary duodenal MALT lymphoma have not yet been validated because of its rarity. This paper reports a case of a 40-year-old male with primary duodenal MALT lymphoma who was treated successfully with radiation therapy alone. A 40-year-old male visited for a medical check-up.Esophagogastroduodenoscopy revealed whitish multi-nodular mucosal lesions in the second and third portions of the duodenum. Biopsy specimens from mucosal lesions in the duodenum were reported to be suspicious for MALT lymphoma of the duodenum. He received a total dose of 3,000 cGy in 15 fractions with external beam radiation therapy for three weeks. Three months after radiation therapy, an endoscopic examination revealed complete resolution of the duodenal lesions. The follow-up 12 months after radiation therapy showed no evidence of tumor recurrence.

Myocardial infarction is usually associated with thrombotic occlusion of an artherosclerotic coronary artery. Reperfusion induced by administration of thrombolytic agents may presserve myocardial function and reduce mortality. At a mean of 272 minutes from symtom onset, 7 patients with acute myocardial infarction received recombinant tissue-type Plasminogen Activator. The results are as followings: 1) Reperfusion of the infarct-related artery was observed in all of the 5 patients in whom coronary angiography was performed 19 hour after initiation of drug infusion. Ergonovine challenge test, done in 1 patient who showed normal coronary artery, did not induced coronary spasm. 2) The maximal value of Creatine Kinase and Creatine Kinase-MB(2098+/-2107U/L and 728+/-532U/L, respectively) occured at 7.2+/-4.3 hour, respectively. A nadir value of fibrinogen(42+/-21% of the preinfusion value) occured at 3.1+/-2.0 hour. 3) Major bleeding episodes occured in 3 patients. Major cardiac events were angina followed by percutaneous transluminal coronary angioplasty in 1 patient; cardiogenic shock in 2 patients, one of whom also experienced recurrent ventricular tachycardia;reinfarction in 1 patient, 3 of the 7 patients died.

BACKGROUND AND OBJECTIVES: Tuberculous (TB) pericarditis is a major cause of constrictive pericarditis requiring pericardiectomy. We sought to determine initial prognostic factors in patients with TB pericarditis. SUBJECTS AND METHODS: We evaluated initial presentation and clinical outcomes (mean follow-up 32+/-27 months) in 60 consecutive patients newly diagnosed with TB pericarditis. RESULTS: Initial presentations were pericardial effusion (PE), effusive-constrictive pericarditis, and constrictive pericarditis in 45 (75%), 9 (15%), and 6 (10%) patients, respectively. Of the 54 patients without initial constrictive pericarditis, 32 (59%) showed echogenic materials in PE, including frond-like exudative coating and fibrinous strands. These patients had a longer disease duration before diagnosis, were initially more symptomatic, in a more advanced state, showed more persistent pericardial constrictions (38% vs. 0%, p<0.001) despite anti-TB medications, and tended to require pericardiectomy more often (19% vs. 0%, p=0.07, p<0.05 by Kaplan-Meier). All patients with effusive-constrictive pericarditis showed echogenic PE. Of the 60 total patients, 10 (17%) underwent pericardiectomies during follow-up. All of these patients showed initial pericardial constrictions, whereas no patient without initial pericardial constriction underwent pericardiectomy (p<0.001). Seven patients showed transient pericardial constrictions that resolved without pericardiectomy. CONCLUSION: Initial pericardial constriction and echogenic PE are poor prognostic signs for persistent pericardial constriction and pericardiectomy in patients with newly diagnosed TB pericarditis. These results suggest that early diagnosis and prompt anti-TB medication may be critical.

OBJECTIVE: Gene expression of nm23 has been investigated in a number of tumors, including breast cancer, colon cancer, malignant melanoma, and hepatocellular carcinoma. Its down-regulation has been shown to be associated with metastasis or disease progression in some of the tumors. This study was carried out to define the relationship between nm23 protein expression and clinicopathological variables. METHODS: nm23 protein levels were investigated in 64 surgically resected specimens of stage III gastric cancer by immunohistochemical method, and association with clinicopathological parameters and survival rates were determined. RESULTS: The overall expression rates of nm23 was 68.7 %. There was no significant difference between nm23 protein expression and clinicopathological variables such as age, sex, stage, histology, tumor depth, number of metastatic nodes, tumor size, site and method of operation. Statistically, no significant differences between nm23 protein expression and overall survival rates were found. CONCLUSIONS: These results suggest that nm23 protein expression is an unsatisfactory prognostic indicator in stage III gastric adenocarcinoma.

OBJECTIVES: It was recently reported that the administration of T4 during antithyroid drug(ATD) therapy resulted in a significant decrease of antibodies to TSH receptors as well as the rate of recurrence of active Graves' disease following discontinuance of ATD treatment. But, there is still controversy whether combination therapy is efficient. Therefore, the present study was undertaken to evaluate the effect of T4 administration of patient with Graves' disease who were being treated with ATD. METHODS: We studied 56 patients received methimazole(MMI) alone(Group 1) and 48 patients received methimazole plus T4(Group 2), They are diagnosed active Graves' disease at department of internal medicine, Kwang ju Christian Hospital from January, 1994 to December, 1995. All the patients were treated initially with 30mg of methimazole daily for one month after then, in the Group 1(methimazole alone), the dose of methimazole was adjusted as necessary to achieve normal serum concentrations of T3, T4, and TSH. The patients of Group 2(methimazole plus T4) continue to receive the combination of T4 at a dose of 100 microgram daily. Simultaneously, we estimated the serum concentration of T3, T4, TSH and Thyroid-stimulating immunoglobulin(TSI) antibody at every three months. RESULTS: We obtained the following result. In the group 1, mean TSI values were 50.1%(first visit), 30.6%(6months), and 24.7%(1year). And, in the group 2 mean TSI values were 51.8%(first visit), 33.6%(6months), and 22.7% (1year). After 6 months of discontinuing of therapy, the recurrence rate was no significant difference in the two groups (the recurrence rate were 55.4%, 50.0%, respectively P>0.05). CONCLUSION: These results suggest that T4 administration in combination with MMI therapy have no significant effect in a decrease in levels of TSH receptors antibodies and recurrence rate within 6 months discontinuing MMI therapy as compared with MMI treatment alone.

BACKGROUND: We experienced an outbreak of typhoid fever in Chunju area which manifested as severe symptoms and signs, and variable complications. To chracterize the epidemic and to identify a possible source of infection, the clinical findings of patients from the outbreak were analyzed, and the patterns of antimicrobial susceptibility and phage typing of Salmonella Typhi isolates were determined. METHODS: We analyzed a total of 232 patients from the outbreak who admitted to Chunju Presbyterian Medical Center during 1996 August through October. The medical records of the patients were reviewed retrospectively. All isolates of S. Typhi from the outbreak were analyzed for serotyping, antibiogram, and phage typing. Phage typing were performed using Vi- phages for 50 strains isolated from the patients who showed atypical clinical manifestations and unusal complications. RESULTS: The outbreak attacked mainly young femalegroup. The complications observed were: 155 casesof hepatitis, 47 pancytopenia, 20 acute pancreatitis, 13 urinary tract infection, 12 intestinal hemorrhage, 5 disseminated intravascular coagulation, 4 meningitis, 3 septic shock, 2 sensorineural hearing loss, 2 myocardial ischemia, 2 pneumonia, 1 stillbirth, and 1 death. S. Typhi were isolated in 129 cases including 111 from blood, 17 stool and 1 urine. All isolates were susceptible to all antimicrobial agents tested. All 50 isolates from severe patients with unusal complications were identified as Salmonella, serogroup D1, serotype Typhi, phage type D1. CONCLUSIONS: We experienced an outbreak of typhoid fever associated with severe, atypical symptoms and unusual complications, caused by Salmonella, serogroup D1, serotype Typhi, phage type D1.
