BACKGROUND: Endocrine pancreas tumor is a rare disease which incidence is less than 2% of all pancreatic tumors. But it comprises various types of tumor and usually secretes several hormones from one type of tumor although the patient with this tumor complains of sole symptom associated with only one hormone. The mechanism and clinical significance of multiple hormone secretion in the endocrine pancreas tumom are not yet clearly defined. METHODS: We analyzed retrospectively the clinicopathologic features of 20 cases which were operated at Seoul National University Hospital during the period between February 1989 and May 1998. RESULTS: The most common tumor was insulinoma (13 cases) and the second most common tumor was nonfunctioning tumor (6 cases). There was one case of somatostatinoma. Most of the patients with insulinoma complained of neuroglycopenic symptoms. There were 9 cases (45.0%) in which the tumors secreted more than two kinds of hormones, 7 cases in insulinoma, 2 cases in nonfunctioning tumors. Whether the tumor secreted multiple hormones was detected by the method of immunohistochemical staining. Though the tumors secreted more than two kinds of hormones, the patients with the tumors complained of symptoms which were associated with the cell type most strongly stained by immunohistochemical method. Whether or not the tumors secreted multiple hormones was not associated with the pathologic features such as tumor size, histologic patterns of the tumor, status of tumor cell differentiation and malignancy. CONCLUSION: From this results, we suggest that endocrine tumors of the pancreas secreted multiple hormones not by the mechanism of dedifferentiation from already differentiated endocrine cells but by the mechanism of neogenesis of multipotent islet stem cells. Since the relationship between the function of multiple hormone secretion in the endocrine pancreas tumors and islet stem cell would be significant, further study should be needed to find out the function of stem cells and application of stem cells to clinical use.

PURPOSE: To investigate the prognostic factors and effectiveness of postoperative radiotherapy alone for endometrial carcinoma. MATERIALS AND METHODS: Sixty four patients with stage I-III endometrial cancer (EC) treated with postoperative radiotherapy alone between January 1989 and December 2008 at the Keimyung University Dongsan Medical Center were chosen for the present study. Typically, total hysterectomy, salpingo-oophorectomy and lymphadenectomy were performed on the patient's pelvis. Total dose from 50.4 Gy to 63 Gy was irradiated at pelvis or extended field. Thirteen patients were treated with Co-60 or Ir-192 intracavitary radiotherapy. Follow-up periods were from 7 to 270 months, with a median of 56 months. RESULTS: Five year overall survival (OS) rate was 58.7%, respectively. Five year disease-free survival (DFS) rate was 59.2%, respectively. In univariate analysis for OS and DFS, stage, menopausal age, type of operation, serosal invasion, and lymph node involvement were found to be statistically significant. Histologic type was marginally significant. In multivariate analysis for OS and DFS, stage, types of operation, histologic type were also found to be statistically significant. Treatment failure occurred in 14 patients. The main pattern of failure was found to be distant metastasis. Time to distant metastasis was from 3 to 86 months (median, 12 months). There were no grade 3 or 4 complications. CONCLUSION: Stage, types of operation, and histologic type could be the predictive prognostic factors in patients. We contemplated postoperative radiation as effective and safe treatment method for EC. Additional treatment would be needed to reduce distant metastasis.

BACKGROUND: The purpose of this study was to analyze the endotracheal intubation cases performed in the emergency department. METHODS: We investigated retrospectively 326 cases of endotracheal intubation performed in the emergency department of a tertiary care center from April 1, 1998 to March 31, 1999. We focused on operators, medications used, its success rate and immediate complications, and the relationship between its success rate and medications. RESULTS: Of 326 consecutive intubations, 193 patients(59.2%) were done by emergency medicine residents or attending physician. While 320 patients(98.2%) were successfully intubated, 6 patients could not be intubated and 2 patients underwent tracheostomy. Of 50 cases of intubations(15.3%) attempted with paralyzing agents, 48 cases were done with succinylcholine and 46 cases underwent by emergency physicians. Intubations with neuromuscular paralysis resulted in high success rates at the first attempt. Of 55 immediate adverse events were encountered in 47 patients(desaturation=17, bronchial intubation=15, hypotension=8, bradycardia=4, cardiac arrest=2, others=5). CONCLUSION: At this institution, paralyzing agents were used infrequently, but almost all of them were used by emergency physicians.

BACKGROUND: The treatment for multi-drug resistant tuberculosis(MDRTB) is encountered to be important clinically, but there are still a few reports about it all over the world. So, we evaluated the outcomes of only chemotherapy for the pulmonary MDRTB retrosptctively. METHOD: We reviewed the clinical courses of 63 patients with pulmonary disease due to M.tuberculosis resistant to rifampin and isoniazid who were under follow-up between March 1996 and June 1996 after hospitalization at our hospital between January 1993 and January 1996. We performed cohort retrospective study for all these patient's records. Their regimens were selected individually and preferably included four medications that they had not been given previously and to which the strain was fully susceptible. RESULTS: The 63 patients(mean age, 43.2 years) had previously received a median 5.1drugs. Fifty two(82.5%) patients responded to chemotherapy(as indicated by negative sputum cultures for at least three consecutive months); eleven patients(17.5%) had no response, as shown by continually positive cultures. In a univariate analysis, an unfavorable response was significantly associated with greater number of resistant drugs before the current courses of therapy(relative risk 21.5; 95 percent confidence interval, 1.2-3.0; p<0.05). The mean period of follow-up was seventeen months. There was no relapse subsequently among the patients with responses. There was no death related to tuberculosis. CONCLUSION: In this report from National Masan Tuberculosis Hospital in Korea, multi-drug resistant pulmonary tuberculosis responded relatively well to carefully selected regimens.

OBJECTIVE: This study was designed to evaluate the correlation of periventricular leukomalacia (PVL) on brain MRI and Denver II and Capute developmental test. METHOD: Thirty children with PVL on brain MRI showing delayed development were included. The severity of PVL was graded as localized/generalized lesion in three fields; periventricular hyperintensity in T2 weighted image (PVHI in T2WI), reduced volume of cerebral white matter (RV of CWM), ventriculomegaly with periventricular wall irregula rity (VM with PVWI). Development quotients were obtained by Denver II and Capute test, and assessed according to the severity of PVL. RESULTS: Although language, fine motor-adaptive, personal- social scale of Denver II and cognitive-adaptive and clinical linguistic and auditory milestone of Capute test had little correlation with severity of PVL, gross motor developmental scale assessed by Denver II had a certain degree of correlation with severity of PVL which was not significant statistically. The gross motor developmental scale of the nineteen preterm births had a significant correlation with VM with PVWI, but the other developmental scales still had no significant correlation with PVL. CONCLUSION: As for the children with delayed development the degree of motor development was a significant predictor of the PVL on brain MRI, but those of language and cognitive development were not.

A 29 years old woman had suffered from posterior neck and right shoulder pain for one year. She was given a spinal manipulation that was by a non-licentiate at a non-hospital. Posterior neck and shoulder pains were worsened and headache was developed after the spinal manipulation. She was recommended to be kept on the manipulation. Although physical finding was non-specific, radiologic findings of CT and MRI revealed atlantoaxial subluxation. After cervical immobilization and anti-inflammatory drug medication for three months, she recovered and did return to her work. We expect that atlantoaxial subluxation after spinal manipulation is not rare even in healthy young person without underlying pathology and can progress to serious complications unless detailed examination and management are undertaken.

BACKGROUND: This study aimed to investigate whether fatty infiltration (FI) measured on a single sagittal magnetic resonance imaging (MRI) slice can represent FI of the whole supraspinatus muscle. METHODS: This study retrospectively reviewed the MRIs of 106 patients (age 50–79 years) divided into three rotator cuff tear-size groups: medium, large, and massive. Fat mass and muscle mass on all T1-weighted sagittal MRI scans (FA and MA) were measured. Of the total MRI scans, the Y-view was defined as the most lateral image of the junction of the scapular spine with the scapular body on the oblique sagittal T1-weighted image. Fat mass and muscle mass seen on this Y-view single slice were recorded as F1 and M1, respectively. Fat mass and muscle mass were also assessed on MRI scans lateral and medial to the Y-view. The means of fat mass and muscle mass on these three slices were recorded as F3 and M3, respectively. Average FI ratios (fat mass/muscle mass) of the three assessment methods (F1/M1, FA/MA, and F3/M3) were compared. Intraclass correlation coefficients (ICCs) were calculated for inter- and intraobserver reliability. RESULTS: ICCs showed higher reliability (> 0.8) for all measurements. F1/M1 values were not statistically different from FA/MA and F3/M3 values (p > 0.05), except in males with medium and large tears. F3/M3 and FA/MA were not statistically different. The difference between F1/M1 and FA/MA did not exceed 2%. CONCLUSIONS: A single sagittal MRI slice can represent the whole FI in chronic rotator cuff tears, except in some patient groups. We recommend measurement of FI using a single sagittal MRI slice, given the effort required for repeated measurements.

Although exercise electrocardiography is commonly used to determine the likelihood of coronary artery disease, data of exercise electrocardiography are limited in Korea. Authors reviewed 409 patients with chest pain who underwent 12 lead treadmill exercise electrocardiography and coronary arteriography at Seoul National University Hospital from January, 1984 through September, 1990. All the patients underwent catheterization within three months after having a standard Bruce protocol treadmill exercise test. None of them had prior myocardial infarction, valvular heart disease, cardiomyopathy, and complete left bundle branch block. The study subjects consisted of 208 patients, including 42 patients of coronary artery spasm, with no or insignificant fixed coronary artery stenosis(less than 50% narrowing of luminal diameter), and 201 with significant fixed stenosis. The results were as follows; 1) The sensitivity of treadmill exercise electrocardiography was 73.6%, and the specificity was 88.2%. Positive exercise test in coronary artery spasm was 21.4%. 2) With increasing the extent of coronary artery disease, the proportion of the patients with one-vessel disease who showed positive ST segment change of stage I increase. Most of the patients with one-vessel disease who showed positive ST segment change on stage I had 90% or more stenosis. 3) With increasing the extent of coronary artery disease, the proportion of the patients with positive ST segment change in multiple lead groups increased. 4) ST segment change appeared most frequently in lead group V4-V6 and next in lead group II III a VF regardless of involved arteries. 5) ST segment elevation in lead group V1-V3 or in I/aVL was usually associated with 90% or more stenosis of left anterior descending artery in one-vessel disease, but similar proportion of the patients was noted in multivessel disease. This suggests that ST segment elevation in lead group V1-V3 or in I/aVL is probably associated with severe ischemia, not a specific predictor of left anterior descending coronary artery disease.
