A 70-year-old female Patient was admitted due to the impression of lung abscess via local clinic. Chest P-A showed air shadow containing huge mass lesion in the right lower lung field, pericardio phrenic angle. But the patient complained of only mild upper respiratioy tract infection symptoms and the laboratory tests were within normal limits. Barium enema and chest C-T taken right after barium enema were performad in suggesting of the diaphragmatic hernia. Barium tilled transverse colon and associated omentum were in the right anterior hemithorax surrounded by the hernial sac. The mass lesion shown in the chest P-A was compatible with the diaphragmatic hemia, Morgagni type. Operative reduction of the herniated bowel and simple closure of the diaphragm was performed.

The authors investigated mortality rate of hospitalized CWP(coal workers' pneumoconiosis) patients. Date, which was composed of age, date of hospitalization, date of death, and radiological findings(profusion of small opacity, type of large opacity, tuberculosis, emphysema, pneumothorax, and cardiac abnormality), was gathered from medical charts and chest x-ray films at the time of hospitalization of CWP patients. Among 738 CWP patients, that were entered survey differently and have followed different period, 160 CWP patients were died during different observational period. Mean value of observational period was 203 weeks, and mean age at hospitalization was 51 years. Because of short observational period, mean survival time could not found. There was statistically significant difference of mortality rate between group of small opacity and that of large opacity. In group of small opacity 5 year survival rate was 0.80 and in group of large opacity that was 0.73. And 80 percentile survival time was 57 months in group of small opacity and that was 40 months in group of large opacity.

BACKGROUND: The effects of a newly synthesized potassium channel opener, KR-30816((-)(nitro-2-hydroxymethyl-2-methy-2H-1-benzopyran-4-y1)pyridine oxide) on the action potential of papillary muscles of guinea pigs and the ATP-sensitive potassium channel current(IKATP) of single ventricular muscle cells of rats were examined to make clear its action mechanism of the KATPchannel. METHODS: We used the conventional microelectrode and the excised inside-out patch configuration. RESULTS: KR-30816 caused a shortening of the action potential duration in dose-dependent manner, which was inhibited by glibenclamide(3microM). Before run-down of the K+channel, KR-30816 activated the cardiac ATP-sensitive K+ channel only in the presence of ATP and shifted the dose-response relation curve between [ATP]i and the channel activity to the right in parallel. After run-down of the KATP channel, KR-30816 did not after the channel opening either in the absence or in the presence of UDP. CONCLUSION: These results suggest that KR-30816 antagonizes the inhibitory effect of ATP on the KATPchannel in a competitive manner, thereby enhancing the channel openings.

BACKGROUND/AIMS: The prevalence of Barrett's esophagus might also be changing along with changes in the epidemiology of GERD, and the incidence of Barrett's cancer is expected to increase even more. The aim of this study is to evaluate the clinicopathologic features and outcome of the patients with Barrett's cancer and who were seen at a single institution over a period of 13 years. METHODS: The records of 39 patients with the esophageal adenocarcinoma and who were treated at Samsung Medical Center from January 1995 to August 2008 were reviewed. Among them, 11 patients (28%) with histologically-confirmed Barrett's cancer were included in the study. The clinicopathological features, endoscopic manifestations and treatment outcome were evaluated. RESULTS: The male to female ratio was 10:1. The mean age was 64 years. Most of the patients were diagnosed with Barrett's cancer after 2000, and there were three such patients (27.3%) in 2008. The frequent chief complaints were epigastric pain (27.3%) and chronic acid reflux symptom (18.2%). Three patients (27.3%) were detected incidentally during screening endoscopy. The macroscopic types based on the endoscopic findings were as follows: 4 lesions with a type IIa appearance (36.4%) and 2 with a type IIb appearance (18.2%). The mean tumor size was 1.2 cm at the longest dimension and 0.8 cm at the shortest dimension. Tumor was located in the mucosal layer in six cases (54.5%) and the 5 cases (45.5%) showed submucosal invasion. Lymph node metastasis was found in one case (9.1%). All the cases underwent surgery, except one case for which the tumor was removed by endoscopic submucosal dissection. There was no recurrence during the follow up period. CONCLUSIONS: As the incidence of Barrett's cancer is increasing, a standard surveillance program that includes the endoscopic biopsy method, the grading system for the dysplasia and the treatment modality should be established.

Authors have recently experienced a rare case of avulsion of the left eye ball due to ocular injury in 7 years old Korean girl. The eye ball was completely exposed out of the lid margin. In this case authors supposed that the dynamic inertia was played a major role in the mechanism of avulsion of this eye ball. A breief review of other literatures has also been described.

BACKGROUND: The recognition of bronchial asthma as an inflammatory disease led to a search for soluble markers that would be useful in assessing airway inflammation. Interleukin-6 (IL-6) is a representative proinflammatory cytokine that has been shown to be connected with various inflammatory diseases. IL-6 acts via specific receptors that consist of the IL-6 binding glycoprotein gp80 and the signal transducer gp130. In the search for markers of airway inflammation, we investigated the role of soluble interleukin-6 receptor (sIL-6R) and IL-6 in acute asthma. METHODS: Serum levels of sIL-6R and IL-6 were measured in 78 acute asthmatics, in 15 patients with asymptomatic asthma and in 10 healthy control subjects by a specific ELISA using a murine antihuman IL-6R, IL-6 mAb (Quantikine sIL-6R, IL-6). RESULTS: Serum levels of IL-6 in acute asthmatics significantly exeeded those of control subjects. Those of sIL-6R in acute asthmatics were also significantly increased compared to those of control subjects. The serum concentration of IL-6 obtained in acute asthmatics was elevated as compared with the asymptomatic asthmatics. However, Association between eosinophilic count / IgE and IL-6 / sIL-6R in acute asthma could not found. CONCLUSION: Our results suggest that IL-6 may be involved in the pathogenesis of acute asthma and serum levels of IL-6 and sIL-6R may reflect the severity of airway inflammation.

Left ventricular mural thrombi can occur in setting of acute myocarditis. Major thromboembolism may occur according to the echocardiographic characteristics of the thrombi. Mobile, irregular and protruding thrombi are known to raise systemic embolism more easily than immobile laminar clot. We experienced a case of a hypermobile pedunculated left ventricular thrombus complicated to acute myocarditis in a 49-year-old woman. Mobility of it increased day by day in spite of the proper anticoagulation. Surgical removal of the thrombus was performed to prevent major thromboembolism.

PURPOSE: A tumor and mature ovarian cystic teratoma rarely coexist, but since it may affect treatment andprognosis, appropriate pre-surgical diagnosis is important. The purpose of this study was to evaluate thedifference in CT findings between a tumor coexisting with a mature ovarian cystic teratoma and a simple matureovarian cystic teratoma. MATERIALS AND METHODS: CT scans of seven cases of tumor coexisting with mature ovariancystic teratoma were reviewed. In each case, size, margin, nature, septation, solid portion, ascites, invasion,and metastasis were analysed. RESULTS: Coexistent tumors were histopathologically diagnosed as squamous cellcarcinoma in three patients, carcinoid in three, and fibrothecoma in one. In contrast with a simple matureteratoma, a tumor coexisting with a mature cystic teratoma developed in older patients and had a more solidportion, which showed contrast enhancement but did not show calcification or a fat component. Where a tumor andmature cystic teratoma coexisted, ascites and the invasion of adjacent structures were also common. CONCLUSION: If, in an older patient, CT scanning reveals an ovarian cystic tumor with a large solid portion but nocalcification or fat, coexistent tumor should be suspected.

PURPOSE: To evaluate the prevalence of capsular retraction in malignant hepatic tumors and the factorsinvolved. MATERIALS AND METHODS: Between January 1994 and December 1996, we retrospectively reviewed the CT scansof 152 patients with pathologically-proven, peripherally-located, malignant hepatic tumors. We evaluated size,site, portal and hepatic venous obstruction, bile duct dilatation, and liver atrophy in 18 cases involvingcapsular retraction. RESULTS: The overall prevalence of capsular retraction among malignant hepatic tumors was18/152(12%) ; the prevalence was 9/129(7%) in hepatocellular carcinoma, 6/14(43%) in cholangiocarcinoma and3/9(33%) in metastatic cancer ; among cases of cholangiocarcinoma and metastatic cancer, the prevalence washigh(p <0.05). Portal venous obstruction was seen in six patients with hepatocellular carcinoma (a high incidence ;p=0.041) and one with cholangiocarcinoma. Hepatic venous obstruction was demonstrated in one patient withhepatocellular carcinoma and one with cholangiocarcinoma. Among cholangiocarcinoma patients, bile duct obstructionwas seen in four and liver atrophy in three, but among metastatic cancer cases there were no similar findings. CONCLUSION: The main factors causing capsular retraction were portal venous obstruction in hepatocellularcarcinoma and bile duct obstruction and liver atrophy in cholangiocarcinoma.

PURPOSE: To compare the clinical outcomes and complications of hemiarthroplasty (HHR) and total shoulder arthroplasty (TSR) in non-traumatic arthritis patients. MATERIALS AND METHODS: Thirty-two patients (34 shoulders) underwent shoulder arthroplasty for nontraumatic shoulder arthropathy. There were sixteen patients with rheumatoid arthritis, nine with osteoarthritis, four with avascular necrosis and etc. HHR was performed in eleven shoulders and TSR in twentythree shoulders. RESULTS: In HHR, the pain score decreased from preoperatively 7.09 to 0.91 postoperatively. The mean forward elevation was 137degrees and the mean external rotation at the side and abduction were 55degrees and 131degrees, respectively. The mean ASES score was 82.4. In TSR, the pain score decreased from 7.04 preoperatively to 1.17 postoperatively. The mean forward elevation, external rotation at the side and abduction were 132degrees, 44degrees, and 132degrees, respectively. The mean ASES score was 81.2. In rheumatoid arthritis, the mean ASES score of the HHR and TSR were 77.8 and 78.1, respectively. In osteoarthritis, the mean ASES score was 84.7 and 90.8, respectively. During the follow up, glenoid erosion was observed in three HHR cases, and glenoid loosening in two TSR case. CONCLUSION: HHR and TSR produced similar results in terms of the functional improvement. The clinical results were much better in patients with osteoarthritis than in those with rheumatoid arthritis, and TSR was performed on most cases of rheumatoid arthritis.
