Thoracoscopic esophagectomy can be performed in esophageal diseases to reduce the postoperative complications. Recently, We encountered a case of esophageal cancer and successfully treated it by thoracoscopic esophagectomy with gastric pull-up. A 59-year-old male was presented with swallowing difficulty and an esophagogram, esophagoscopy, and chest CT showed an ulcerating tumor on the lower esophagus. The operation was performed in three stages: mobilization of the esophagus by thoracoscopic surgery, construction of a gastric tube through a laparotomy, and cervical anastomosis between the esophagus and the gastric pull-through. Hoarseness developed postoperatively, and the postoperative esophagogram showed leakage at the esophagogastric anastomotic site. The anastomotic leakage was healed following surgical drainage and the patient was discharged in good health. Hoarseness subsided spontaneously two months after surgery.

OBJECTIVES: The stress response involves the activation of the hypothalamic-pituitary-adrenal(HPA) axis and the sympathetic nervous system. Corticosteroids have been clearly demonstrated to cause anti-inflammatory and/or immnosuppressive effects in man including granulocytosis in part by decreasing migration into tissue, especially damaged tissues(myocardium), and circulating relative lymphocytopenia. To test whether automated measurements of the the increased serum cortisol-induced hematologic changes in the leukocyte differential significance or not in the initial differential diagnosis of acute myocardial infarction in acute chest pain syndromes. METHODS: 101 consecutive patients with myocardial infarction or myocardial ischemia presenting to the emergency room of Seoul Adventist Hospital with acute chest pain from January 1993 to August 1995(Retrospective group) and from December 1995 to March patients compatible with exclusion criteria in myocardial infarction were excluded. We measured automated leukocyte differential and serial CK-MB level in both groups, and the intial serum cortisol levels in prospective infarction group. RESULTS: 1) Total leukocyte and granulocyte counts were increased in acute myocardial infarction(p<0.01). 2) In acute myocardial infarction group, lymphocyte counts were slightly increased(p<0.05), but relative lymphocytes percentage more significantly decreased(p<0.01). 3) Serum cortisol levels are significantly raised early in the course of the acute myocardial infarction and prior to the elevation of the specific cardiac enzymes on the basis of analytic results of prospective infarction group. 4) Cortisol-induced changes in leukocyte differential were noted with time passes into reverse approximately 4 days later in our study. 5) The leukocyte differential does not shows significant changes in the retrospective myocardial ischemia group, so we arrive in careful conclusion that serum cortisol level seems does not increase. 6) No sexual differences were noted in leukocyte differential. CONCLUSIONS: The serum cortisol level and cortisol-induced leukocyte differential are helpful for initial differential diagnosis of acute myocardial infarction in acute chest pain sysdrome.

PURPOSE: Conventional pathologic classifications of human renal cell carcinoma give little insight into oncogenesis and little assistance in predicting the clinical behavior of this disease. For genetic classification, deletion of the short arm of chromosome 3(3p), the hallmark of nonpapillary/clear cell RCC, is a major diagnostic criterion. Because of the limited routine applicability of cytogenetics and molecular genetic techniques we investigated fluorescence in situ hybridization(FISH) for the detection of this aberration in RCC. MATERIALS AND METHODS: Isolated nuclei from 8 human RCC paraffin embedded tissue sections were examined with a dual color FISH technique for loss of chromosome 3p. Telomeric DNA probe from 3p and an internal ploidy control probe, centromeric probe of chromosome 2, were applied to the isolated nuclei of RCC. RESULTS: 87.5% of the patients(7) lost chromosome 3p. The loss of 3p in the samples tested was unrelated to patient age, gender, tumor stage, and grade. CONCLUSIONS: FISH for the detection of loss in 3p from paraffin embedded tissue sections provides a sensitive and feasible methods for the genetic classification of kidney tumors and FISH is a very useful diagnostic tool for detection of the genetic aberrations of the tumors.

PURPOSE: To implant tissue chips in New Zealand rabbits, and thus redurce the frequency with which scattered VX2 carcinoma nodules and early metastasis develop in these animals. MATERIALS AND METHODS: VX2-carcinoma tissue chips of two different sizes were implanted under ultrasonographic guidance. In each of 12 New Zealand rabbits (group 1), there 1-mm tissue chips were implanted in the liver using an 18-gauge needle, and in the same way, one 3-mm chip with an added gelfoam pellet was implanted in the proximal lumen of the liver of each of ten other New Zealand rabbits (group 2). Three weeks after implantation, the animals underwent dvalphase CT scanning and were sacrificed, and the Number and size of tumor nodules, and metastasis were evaluated either macro-or microscopically. RESULTS: In ten rabbits in group I, a total of 21 nodules (16 in the liver, 5 in the peritoneal wall) were observed, which in nine rabbits in group 2, a total of ten nodules-all in the liver-were present. CT scans depicted tumor nodules in 50% of group-I rabbits, and in 29% those in group 2. Mean tumor diameter was 12 +/-9 mm in group 1 and 6.4 +/-3 mm in group 2. Histologic examination indicated the presence of nodular VX2 carcinoma, with varying degrees of central necrosis, a feature more prominent in group 2. CONCLUSION: To provide a well-localized tumor nodule in rabbit liver, tissue chip implantation of VX2 carcinoma, especially with added gelfoam, is a good alternative to intraparenchymal injection of tumor suspension.

OBJECTIVES: The anthors examined health-seeking behavior about using herbal medicine in psyciatric and other clinical patients. The effect, side effect and motives in selecting herbal medicine were examined also. This study aimed at presenting treatment guide for psychiatric patients hereafter. METHOD: Subjects were consisted of 277 patients who were 93 medical, 81 surgical, and 102 psyhiatric patients. We made a questionnaire checking circumstances on taking herbal medicine. The investigating psychiatrist conducted person to person semi-structured interview using this questionnaire. RESULTS: Psychiatric patients preferred herbal medicine to western medicine, as other clinical patients did. In their health seeking behavior, classical illness model of oriental herbal medicine occupied a central position. In addition, psychiatric patients not only regarded herbal medicine as a more symtom-specific therapeutic medication, but also accepted side effects of herbal medicine uncritically than other clinical patients. CONCLUSIONS: As it is known that many psychiatric patients take both oriental and western medical treatment, we should not have exclusive attitude to emphasize one side between oriental and western medicine. Rather, we should deepen our understandings about oriental herbal medicine.

PURPOSE: The purpose of this study was to evaluate the incidcnce of extrapericardial fat in the left cardiacborder, and with regard to left extrapericardial fat, to correlate chest radiographs with CT scans. MATERIALS AND METHODS: This study involved 132 consecutive patients who underwent chest PA and lateral radiographs, and chestCT scans. According to the results of chest PA radiograph, patients were divided into three groups: those with aclear left cardiac border; those with an indistinct left cardiac border; and those with an indistinct left cardiacborder with increased density; cardiophrenic angle, as seen on lateral radiograph, the presence of increaseddensity in the anterior cardiophrenic angle, as seen on lateral radiograph radiographs was evaluated. On the basisof the results of CT scanning, patients were classified into four groups according to the amount of leftextrapericardial fat: negative, minimum, moderate, and maximum. Left extrapericardial fat, as seen on CT, wascorrelated with the conspicuity of left cardiac border seen on PA radiograph and the presence of increased densityin the anterior cardiophrenic angle, as seen on lateral radiograph. RESULTS: On CT, left extrapericardial fat wasobserved in 51 patients (38.6%). In 38 of these (28.8%), the amount was minimal, in 12 (9.1%), it was moderate,and in one (0.8%), it was maximal. On posteroanterior chest radiograph, clear, indistinct, and indistinct andincreased density of the left cardiac border was seen in 89 (67.4%), 28 (21.2%), and 15 cases (11.4%),respectively. On lateral radiograph, increased density of the anterior cardiophrenic angle was seen in 115 cases(87.1%) but in 17 (12.9%), increase density was not apparent. There was significant correlation between chestradiographs and CT(p<0.001) (sensitivity: 53%; specificity: 100%; positive predictive value: 100%; negativepredictive value: 84%). CONCLUSION: The conspicuousness of the left cardiac border, as seen on PA chestradiograph, correlated with the presence of left extrapericardial fat, as seen on CT, and was related to theamount of left extrapericardial fat. Increased density of the anterior cardiophrenic angle, as seen on lateralradiographs, correlated with the presence of left extrapericardial fat on CT, but the absence of increased densityon lateral radiograph corresponds to the absence or a minimal amount of left extrapericardial fat, as seen on CT.

BACKGROUNDS: In the absence of distant metastasis, small cell lung cancer (SCLC) patients presenting with supraclavicular lymph node (SCLN) involvement and pleural effusion can benefit from thoracic radiotherapy. But there are some debate as to the prognostic significance of both SCLN involvement and pleural effusion. The purpose of this study was to determine the prognostic significance of SCLN involvement and pleural effusion in SCLC. METHODS: Two Hundred and fifteen patients with histologically confirmed small cell lung cancer, who were treated either at the Keimyung university Dongsan hospital and Kyungpook national university hospital from January 1994 to June 1998, were evaluated retrospectively. The patients were classified as having either limited or extensive stage using the Veterans Administration staging system. RESULTS: SCLN was presented in 10.5% of patients(n=21). The median survival was 247 days for patients with SCLN(n=21) and 264 days for patients without(n=194) (p=0.52). After treatment, the median survival was 298 days for patients with SCLN(n=13) and 348 days for patients without(n=115) (p=0.52). SCLN involvement was not correlated with the presence of distant metastases. Medican survival was 459 days for patients with a limited stage without SCLN(n=66), 650 days for those with a limited stage with SCLN (n=7) (p=0.96). Pleural effusion was presented in 24.7% of patients(n=52). The median survival was 198 days for patients with pleural effusion(n=52) and 275 days for patients without(n=163) (p<0.05). After treatment, the median survival was 294 days for patients with a pleural effusion(n=25) and 286 days for patients without(n=103) (p=0.39). The presence of pleural effusion was not correlated with that of distant metastases. The median survival was 395 days for patients with a limited stage without a pleural effusion(n=63), 451 days for those with a limited stage with pleural effusion(n=10) (p=0.92). CONCLUSIONS: In this study, SCLN involvement does not explain the poor survival rate and the relevance to extensive staged disease. Furthermore, the existence of a pleural effusion did not correlated with the presence of distant metastases. However, the presence of a pleural effusion appears to be a minor prognostic factor in our study. Therefore supraclavicular lymph node justify any amendment to the staging system currently used.

BACKGROUNDS: Assessment of the presence and degree of reversibility of airflow obstruction is clinically important in patients with asthma or chronic obstructive pulmonary disease. The measurement of peak expiratory flow(PEF) is a simple, fast, and cheap method to assess the severity of obstruction and its degree of reversibility. Assessing the reversibility of airflow obstruction by peak expiratory flow(PEF) measurements would be is practicable in general practice, but its usefulness has not been well investigated. We compared PEF and FEV1 in assessing reversibility of airflow obstruction in patients with chronic obstructive pulmonary disease or asthma and developed a practical criterion for assessing the presence of reversibility in general practice. METHODS: PEF measurements were performed (Spirometry) in 80 patients(aged 24-78) with a history of asthma or chronic obstructive lung disease before and after the inhalation of 200 mg salbutamol. The change in PEF was compared with the change in forced expiratory volume in one second(FEV1). Reversible airflow obstruction was analysed analyzed according to American Thoracic Society(ATS) criteria. RESULTS: When defined as a 12% A 12% increase above the prebronchodilator value and a 200ml increase in either FVC or FEV1 reversibility was were observed in 45%(36) of the patients. Relative operating characteristic(ROC) analysis showed that an absolute improvement in PEF of 30l/min gave optimal discrimination between patients with reversible and irreversible airflow obstruction(the sensitivity and specificity of an increase of 30l/min in detecting a 12% increase above the prebronchodilator value and a 200ml increase in either FVC or FEV1 were 72.2% and 72.7% respectively, with a positive predictive value of 68.4%) CONCLUSIONS: Absolute changes in PEF can be used to diagnose reversible airflow obstruction.

BACKGROUND: Considering that both humoral and cell mediated immunities play an important role for human tuberculosis infection, enzyme-linked immunosorbent assay(ELISA) measurement of immunoglobulin G (IgG) antibody to mycobacterial antigens can be used for the serologic diagnosis of tuberculous pleural effusion. METHOD: We measured absorbance values of IgG antibodies to purified-protein-derivative (PPD) and lipoarabinomannan-B (LAM-B) in the pleural fluid (PF) and the serum in 40 tuberculous (TPE) and 19 nontuberculous pleural effusions (NTPE). RESULTS: 1) The IgG antibodies to PPD and LAM-B were significantly (P<0.0005) higher in the PF and the serum of TPE compared to NTPE. 2) The IgG antibodies to PPD and LAM-B in the serum were higher than that in PF. 3) Significant correlations were found between pleural and serum IgG antibodies to PPD and LAM-B. 4) With a cutoff value for IgG antibody to PPD in the PF of 0.091, sensitivity was 55.0% and specificity 94.7% in the diagnosis of TPE. 5) With a cutoff value for IgG antibody to LAM-B in the PF of 0.337, sensitivity was 50.0% and specificity 94.7% in the diagnosis of TPE. 6) The seropositive rates in TPE were not related to PPD skin test status, the amount of PF and coexisting active pulmonary tuberculosis. CONCLUSION: The assay of IgG antibodies to PPD and LAM-B might be useful for the diagnosis of TPE. Our study suggests the mechanism of passive transfer of IgG antibodies to PPD and LAM-B from the serum to the PF through pleural tissue.
