A retrospective review of 102 patients with metastatic bone tumor seen at Hanyang University Hospital from 1986 to 1990 was performed. We analyzed the cases in the aspects of primary lesions, age and sex distributions, locations and number of metastatic foci, compared with those in the previous reports in Korea. l. 54.9% of the patients were male and 45.1% were female. The incidence of the metastatic bone tumors in female compared with the previous incidence before 1980's years was relatively increased. The peak age was in the 6th decade. The incidence younger than 50 years was decreased, and the incidence older than the 7th decade was relatively increased. 2. The main primary cancers were lung(40.2%), liver(11.8%), breast(10.8%), unknown(8.8%), and uterine cervix(6.9%) etc. In cases of lung cancer, the frequent histologic types were adenocarci noma, squamous cell carcinoma, and small cell carcinoma. 3. The vertebrae(56.9%), ribs(40.2%), femur(17.6%), pelvis(15.7%) were relatively frequent sites of metastasis which involved multiple metastasis. 4. Single metastasis(62.4%) was more frequent than multiple metastasis(37.6%). 5. In the primary cancers, the incidence in hepatoma of male was increasing, the incidence in lung cancer of female was relatively increasing, but the incidence in stomach cancer was decreasing.

The purpose of this study is to evaluate the results of bone graft or cement fill for tibial bone defect in total knee arthroplasty. 51 knee in 45 patients which had bone graft or cement fill for tibial bone defect of more than 1cm3 in total knee arthroplasty, between March, 1990 and July, 1994 at the department of Orthopedic Surgery in Hanyang University Hospital were followed for average 30 months. Bone grafts were performed in 33 knees and cement fills in 18 knees. The size of tibial defect was measured after removal of sclerotic and dense bone in the tibial plateau. The average size of tibial defect treated by bone graft was 4.9 cm3 in volume, 11 mm in height and the average size of tibial defects treated by cement fills was 1.5cm3 in volume, 6.8 mm in height. The results were as follows ; 1. In true A-P and lateral x-ray checked by fluoroscopic guide, trabecular union was seen in all 33 knees of bone grafts without collapse, loosening and bone resorption. In one of 18 knees of cement fill, radiolucent line was detected 2 mm in width between cement mantle and the adjacent tibial bone. In other 17 knees, radiolucent was seen 1 mm or less in width. 2. According to the system of Knee Society Score, average knee rating score was improved from 23.2 points preoperatively to 90 points postoperatively in bone graft cases, from 23.4 points preoperatively to 93.2 points postoperatively in cement fill cases. Average functional score was improved from 14.8 points preoperatively to 81.5 points postoperatively in bone graft cases, from 13.3 points preoperatively to 81.4 points postoperatively in cement fill cases. 3. Finally, we obtained the good results by cement fill during cement fixation of tibial component or bone graft without cement fixation of tibial component for small tibial bone defect and by bone graft for large tibial bone defect.

Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.

Asymmetrical Septal Hypertrophy(ASH), Characterized by interventricular septal hypertrophy, is not an uncommon cardiac disease. Arrythmia occuring in ASH are supraventricular tachycardia, atrial premature beats, and ventricular premature beats. In about 10% of patients, there is a short P-R interval and a partial delta wave, suggestive of a variant of the Wolff-Parkinson-White syndrome. We reported here a case of ASH associated with W-P-W syndrome and paroxysmal atrial fibrillation with review of pertinent literatures.

PURPOSE: To evaluate the plain radiographic and CT findings of the necrotizing fasciitis. MATERIALS AND METHODS: We retrospectively reviewed the radiologic findings of 4 cases with necrotizing fasciitis. Three cases were proven pathologically. We evaluated pattern and extent of the gas shadows in plain films. CT findings were analysed, with emphasis on : (a) gas pattern, (b) extent, (c) location and involved site, (d) associated focal abscess, and (e) swelling of the adjacent muscles. RESULTS: On plain radiographs, four cases showed streaky or mottled gas densities in the pelvis, three cases in the perineum, one case in the abdomen, and two cases in the thigh. On CT images, gas pattern was mottled and streaky appearance with swelling of the adjacent muscles. Gasshadows located in the extraperitoneal space in four cases, fascial layer in four cases, and subcutaneous layer infour cases. There were gas shadows in pelvic wall, perineum, abdominal wall, buttock, thigh, and scrotum. Focallow density lesion suggestive of focal abscess was not visualized. CONCLUSION: Plain radiography is useful forearly diagnosis of the necrotizing fasciitis and CT is very useful for detection of precise location and extent of the disease. CT is also useful for differentiation of necrotizing fasciitis from focal abscess and cellulitis.

BACKGROUND: It is often difficult to make a diagnosis of cardiac ischemia in patients attending emergency department (ED) with symptoms of acute coronary syndromes (ACS) because existing cardiac markers are not sensitive for reversible myocardial ischemia. Ischemia modified albumin (IMA) has recently been shown to be an early and sensitive marker of myocardial ischemia. We investigated the usefulness of ischemia modified albumin (IMA) as an early triage marker for ACS and tried to establish a newly standardized albumin-adjusted IMA index which has been expected to be more sensitive and accurate than conventional IMA value. METHODS: We enrolled 209 consecutive patients (men 95, women 114) who presented to the ED with symptoms suggestive of ACS from June to July, 2005. All patients were classified to ACS group (n=42) and others (n=167) based on diagnosis of cardiologists. The ideal cutoff value of IMA was calculated by the receiver operating characteristic (ROC) curve analysis and diagnostic utilities of combination tests (myoglobin, CK-MB, troponin T and EKG) were compared with those of IMA. The albumin-adjusted IMA index was calculated and applicated from the results of correlation assay between serum albumin concentration and IMA value. RESULTS: Mean IMA level (U/mL) of ACS group was significantly higher than that of non-ACS group (P<0.05) and sensitivity and specificity was 92.9% and 35.9% at a cutoff value of 85.1 U/mL, respectably. In combination with conventional cardiac markers, the sensitivity increased to 96.3%. IMA value had a negative lnear relationship with serum albumin concentration (YIMA= -23.1Xalbumin+200, R=0.99) and albumin-adjusted IMA index was calculated as [IMA index = serum albumin conc. (g/dL) x 23 + IMA (U/mL) -100]. The sensitivity and specificity was 97.6% and 34.1% at a cutoff value of 83.3 IMA index, respectively. CONCLUSIONS: IMA is a useful sensitive marker for the identification of ACS in patients with normal cardiac markers and EKG finding and follow-up combination testing may be required to rule out other diseases. The calculated albumin-adjusted IMA index is recommended to make a diagnosis of ACS more sensitively.

The endoscopic diagnosis of gastric carcinoid has been considered difficult. Reported cases of this tumor diagnosed by endoscopic examination are rare. And the gastric carcinoid with massive upper gastrointestinal bleeding is a rare disease entity. We experienced a case of gastric carcinoid admitted to the hospital because of hematemesis, melena and syncope. And it was diagnosed by endoscopic biopsy, although it resembled type IIa+IIc early gastric cancer at endoscopic examination. To our knowledge, this is the first case report of gastric carcinoid tumor mimicking early gastric cancer. So we report this case with a review of relevant literatures.

PURPOSE: To study the concentration of vascular endothelial growth factor (VEGF) in the aqueous humor before and after intracameral injection of bevacizumab in eyes with neovascular glaucoma, and to detect the duration of an anti-VEGF effect of bevacizumab in the anterior chamber. METHODS: In this prospective interventional case series, 1.25 mg of bevacizumab was injected into the anterior chamber of five eyes in five neovascular glaucoma patients. Aqueous humor samples were obtained just before intracameral injection of bevacizumab and two weeks after injection. The concentrations of VEGF in the aqueous humor were measured using ELISA. To investigate corneal endothelial damage after intrecameral bevacizumab injection, specular microscopy was performed before injection and two weeks after injection. Slit lamp photo and iris fluorescent angiography was performed to determine the regression of iris neovascularization. RESULTS: After injection, substantial regression of neovascularization or fluorescein leakage was seen in all treated eyes. The VEGF concentrations in the aqueous humor in eyes with NVG were 1181.8+/-1248.3 pg/mL before intracameral injection of bevacizumab. Two weeks after injection, the VEGF concentrations decreased to 33.2+/-12.2 pg/mL (p=0.04, Wilcoxon signed rank test). There were no significant changes in IOP or corneal endothelial cells. CONCLUSIONS: Intracameral bevacizumab injection can remarkably reduce iris neovascularization in neovascular glaucoma patients. VEGF levels were significantly decreased two weeks after injection and corneal toxicity was not observed during short term follow-up.
