Isolated heaptic tuberculous granuloma with no coexistent tuberculosis elsewhere in the body is extremely rare. We report a case of pathologically proven tuberculous granuloma in the liver followed with both IV bolus and portal CT scans. The lesion on preenhanced CT scan showed undefinable isodensity. After IV bolus injection, it showed poor enhancement with central low-density and surrounding hyperdenity due to compensatory hypervascularity of the left lobe of liver in early phase. It showed peripheral rim enhancement in late phase and in delayed phase showed relatively homogeneous but slightly decreased contract enhancement. On portal CT scan, it showed a hypodense portal defect similar to other hepatic mass lesions. During follow-up studies, it was a slowly growing mass which was more easily detectable by prtal CT scans than bolus CT scans.

Esophageal ulcers induced by doxycycline is a rare complication. These patients usually complain of sudden onset of symptoms, ie acute substernal or chest pain and odynophagia without prior hietory of esophageal syraptoms. On esophagoscopic examination, there are upper or midesophageal ulcers, which heal after diseontinuation of the drug within 2 weeks. A history of ingestion of the doxycycline,with liquid jost before bedtime can be elicited. The exact eause of the xaucosal ulceration is not clear, but a direct irritant effeet on esophageal mucosa seems most likely. We report 5 cases of esophageal uleeration secondary to the ingestion of doxycydine. Esophagoscopy revealed esophageal ulcers in all patients and the patients hecame asymptomatic following stopping of tbe drugs and taking antacids.

Pathologic fracture is a bresk of bony continuity within an abnormal bone. The abnormslity ma be due to systemic skeletal disease, infection, primary benign and malignant tumor, or metastati carcinoms. Among these, metastatic carcinoma to bone is most common cause of pathologic fractur excluding those due to osteoporosis. When considering the msnagement, pathologic fractures due to systemic skeletal disease usually heal with conservative treatment, while others often require operative treatment. We have experienced 20 cases of pathologic fracture in long bones for 8 years from 19 to 1987. The results were as follows ; 1. The average sge was somewhat different according to underlying diseases Malignant tumorous lesion; 53 years Benign tumorous lesion ; 17 years Chronic osteomyelitis, 42 years 2. The most common cause was malignant tumorous lesion, 8 cases(40%). 3. The most frequent site was femur, 17 cases(85%). 4. Surgical treatment was done in 17 cases(85%), and conservative treatment was done in 3 cas(1sw). 5. In 3 cases of pathologic fractures due to metaststic tumor, the pain was markedly relieved and essy nursing care was possible immediately after operation.

The ankle joint is a modified complex hinge joint which plays an important role in weight bearing, walking and standing. Injuries about the ankle joint cause destruction of not only bony architecture but often also the ligamentous and soft tissue component. So the goal of the treatment of ankle fracture is restoring normal relations of ankle mortise and regaining a smooth articular surface. The author have reviewed 84 cases of ankle fractures which were treated through the admission in the Orthopedic Department, In Je Medical College Pusan Paik Hospital from June 1979 to August 1986. The average duration of the follow-up was one year. The results obtained from this study were as follows : 1. The most common type was Danis-Weber type C. Nexts were B and A in order. According to the classification of Lauge-Hansen, the most common type was Pronation-external rotstion(39.2%). 2. In Danis-Weber type B and C, satisfactory result was obtained by operative treatment. 3. Danis-Weber's classification was very practical criteria for treatment of the ankle fracture.

Pott's paraplegia has been frequently serious complication of tuberculous spondylitis, although antituberculous drugs have improved the prognosis and healing of the disease. There are much controvercy on treatement of Pott's paraplegia, which comprises immobilization with or without anterolateral antituberculous drugs, immobilization and early posterior arthrodesis, anterolatear decompression and radical anterior decompression with anterior spinal fusion. The method of anterior decompression and anterior interbody fusion which was introduced by Hdgson since 1956 has good reults. The author analyzed 27 consecutive cases of Pott's parsplegia operated at orthopedic departement, In Je Paik Hospital from May 1980 to August 1988. The results were as follows, 1. Number of cases in child was nine(33%), both sexes were similar. 2. Regions of spine involved were most common at thoracic spine(62%). Number of affected vertebrae was averaged 3.3 vertebrae. 3. There were nineteen early(70%) and eight late(30%) paraplegia. 4. There were two complete and twenty five incomplete paraplegia. 5. In operative finding, inflammatory products and sequestrated material was extrinsic factor in early in paraplegia. 6. The recovery of the paraplegia occur in twenty cases(74%) 7. The recovery of paraplegia after treatment was far better in type of early onset, type of incomplete paraplegia less than one year duration. 8. The radical anterior decompression and anterior interbody fusion was considered as recommendable method for remove of all pathologic foci, recovery of paraplegia and healing the tuberculosis with stability.

Gorham's syndrome is a rare disorder involing a proliferation of vascular channels associated with extensive loss of bony matrix. It starts in bone, but it may secondarily involve soft tissue and adjacent bones. Although the osteolysis usuakky arrests spontaneously, its biologic behavior is difficult to predict. The mechanism of steolysis is unkown, and the role of osteoclasts is controverwial We have experienced one case of Gorham's syndrome affecting the scapula and clavicle, which is reported in this paper with brief review of literature.

PURPOSE: To evaluate the relationship between metabolic syndrome and benign prostatic hyperplasia in Korean men, we investigated the relation between prostate volume and the serum prostate specific-antigen (PSA) level with the factors for metabolic syndrome. MATERIALS AND METHODS: We reviewed the data of 1,412 men who had a general health check-up without significant evidence of disease between January 2004 and May 2007. The age, prostate volume, PSA, PSA density and metabolic factors were measured, and the relationships of these factors were evaluated. We also compared the prostate-related data between the metabolic syndrome(MS) group and non-metabolic syndrome(NMS) group. RESULTS: The prostate volume was significantly larger in the MS group (23.0+/-7.1ml) than that in the NMS group(20.9+/-6.1ml)(p<0.001). There was no statistically significant difference of the PSA level between the two groups(MS group: 0.86+/-0.66, NMS group: 0.90+/-0.81), but the PSAD was significantly different between the two groups(MS group: 0.038+/-0.027, NMS group: 0.044+/-0.031)(p=0.0035). We concluded that there was a significant correlation between the prostate volume and the metabolic syndrome factors. However, when analyzing the influence of each metabolic syndrome factor on the prostate volume, only the BMI was a relatively influential factor. CONCLUSIONS: Our study showed that there was significant correlation between each metabolic syndrome factor and the prostate volume. This seemed to be the result of the commonly related pathophysiology of MS and an enlarged prostrate volume, and obesity was a significant factor. It was meaningful that the PSA level in the MS group was lower than that of the NMS group in case of the same prostate volume.

OBJECTIVES: The objective of this study was to evaluate the performance of risk-adjusted mortality models for colorectal cancer surgery. METHODS: We investigated patients (n=652) who had undergone colorectal cancer surgery (colectomy, colectomy of the rectum and sigmoid colon, total colectomy, total proctectomy) at five teaching hospitals during 2008. Mortality was defined as 30-day or in-hospital surgical mortality. Risk-adjusted mortality models were constructed using claims data (basic model) with the addition of TNM staging (TNM model), physiological data (physiological model), surgical data (surgical model), or all clinical data (composite model). Multiple logistic regression analysis was performed to develop the risk-adjustment models. To compare the performance of the models, both c-statistics using Hanley-McNeil pair-wise testing and the ratio of the observed to the expected mortality within quartiles of mortality risk were evaluated to assess the abilities of discrimination and calibration. RESULTS: The physiological model (c=0.92), surgical model (c=0.92), and composite model (c=0.93) displayed a similar improvement in discrimination, whereas the TNM model (c=0.87) displayed little improvement over the basic model (c=0.86). The discriminatory power of the models did not differ by the Hanley-McNeil test (p>0.05). Within each quartile of mortality, the composite and surgical models displayed an expected mortality ratio close to 1. CONCLUSIONS: The addition of clinical data to claims data efficiently enhances the performance of the risk-adjusted postoperative mortality models in colorectal cancer surgery. We recommended that the performance of models should be evaluated through both discrimination and calibration.

PURPOSE: To evaluate the histological changes of the synovial membrane treated by 166Ho-Chitosan complex in collagenase induced arthritis of the knee in the rabbit. MATERIAL AND METHOD: Arthritis was induced in sixteen rabbits by intra-articular injection of 1mg collagenase II and then treated by intra-articular injection of 0.4mCi 166Ho-Chitosan complex 2weeks later. The radioisotope scan was checked in each rabbit for the distribution and extra-articular leakage of the 166Ho-Chitosan complex. The synovial tissues from the femorotibial joints were evaluated for serial histological changes 2, 4, 8, 12 weeks after the 166Ho-Chitosan complex injetion. RESULTS: Two weeks after 166Ho-Chitosan complex administration, inflammatory cells such as giant cells, lymphocytes, histiocyte, and fibroblasts appeared in the subsynovial stroma. The most synovial cells were necrotized. Four weeks after 166Ho-Chitosan complex administration, the inflammatory cells were decreased and many fibroblasts appeared on the subsynovial stroma. There was neovasculization in the synovial membrane 4 weeks after administration. The fibers of collagen were noticed in the synovial membrane and subsynovial stroma at 8 weeks. There was no synoviocyte in the synovium and the thickness of fibrosis was increased at 12weeks. There were fragmentation of the nucleoli of synoviocyte and endothelial cell on the transmission electron microscope (TEM) . CONCLUSION: This study suggests that the synovial membranes treated by 166Ho-Chitosan complex in the collagenase induced arthritis of the knee in the rabbit show early radiation damage and then subsequently develop the fibrosis, and no synovial cell regeneration was observed until 12 weeks.

Meningioma is a common primary tumor of central nervous system. However, extracranial extension of the intracranial meningioma is unusual, and mostly accompanied the osteolytic change of the skull. We herein describe an atypical meningioma having extracranial extension with hyperostotic change of the skull. The patient was a 72-year-old woman who presented a large mass in the right frontal scalp and left hemiparesis. Brain magnetic resonance imaging and computed tomography scans revealed an intracranial mass, diffuse meningeal thickening, hyperostotic change of the skull with focal extension into the right frontal scalp. She underwent total removal of extracranial tumor, bifrontal craniectomy, and partial removal of intracranial tumor followed by cranioplasty. Tumor pathology was confirmed as atypical meningioma, and she received adjuvant radiotherapy. In this report, we present and discuss a meningioma en plaque of atypical histopathology having an extracranial extension with diffuse intracranial growth and hyperostotic change of the skull.
