A buttonhole deformity of the finger is characterized by flexion of the pmximal interphalangeal joint and hyperextension of the terminal interphalangeal joint. When the central slip of the extensor tendon and the triangular ligament are ruptured,(or severed) on the base of the middle phalanx, buttonhole deformity will result.This article is based on clinical and follow up studies of 5 patients with buttonholedeformities. Five cases were treated by the modified Littler method and were followed from 4 months to 24 months postoperatively and good results were obtained in all cases.

Synovial chondromatosis is an uncommon benign lesion characterized by metaplastic cartilage formation within the synovial connective tissue which disintegrates into the joint and continues to grow. Of the eight cases of synovial chondromatosis seen by the authors, three cases involved the knee, two of these were bilateral, three cases involved the elbow, one the hip joint and one the proximal phalanx of the right middle finger. The diagnosis of synovial chondroamtosis was made by histopathological findings of the excised mass. Most synovial chondromatosis cases obtained favorable results by removing masses from the joint and at the same time performing a partial synovectomy, except one case in which degenerative arth ritis had developed proeoperatively.

PURPOSE: To assess the clinical and pathologic features of each type of intrahepatic cholangiocarcinoma,which is divided into three types according to gross appearance, and to determine the efficacy of CT in detectingthis tumor. MATERIALS AND METHODS: The pathologic and CT features of 53 surgically proven cases of intrahepaticcholangio-carcinoma were reviewed. On the basis of their gross appearance, the tumors were divided into threetypes, as follows: mass forming (n=33), periductal infiltrating (n=6), and intraductal growth type (n=14). CTscans were analyzed for sensitivity of detection and correlation between a tumors appearance and itshistopathology. RESULTS: The most common histopathologic feature of mass forming and periductal infiltrating typewas tubu-lar adenocarcinoma, while in the intraductal growth type, papillary adenocarcinoma (100%) was common.With regard to pattern of tumor spread, intrahepatic and lymph node metastasis were more common in the massforming and periductal infiltrating type than in the intraductal growth type. CT findings including intra-hepaticmass, ductal wall thickening or intraductal mass associated with segmental dilatation of intrahepataic bile ducts,corresponded with these morphologic types. CONCLUSION: This classification according to gross appearance is ofconsiderable value when interpreting the pathologic features of intrahepatic cholangiocarcinoma. CT seems to be auseful modality for the detection of tumors and may be consistent with their gross morphologic findings.

BACKGROUND/AIMS: The aim of this study was to examine the incidence of proximal colon adenoma according to characteristics of distal colon adenoma. METHODS: Ninety-two colon adenoma patients who underwent total colonoscopy and endoscopic polypectomy were analyzed retrospectively. Adenoma was classified as proximal when located in proximal to splenic flexure. The advanced adenoma was defined as an adenoma larger than 10 mm or any size with a villous component or severe dysplasia. RESULTS: The incidence of proximal adenoma was increased significantly in those with old age (odds ratio (OR)=3.3), villous (OR=5.3) or dysplastic histology (OR=8.1) or the presence of advanced distal adenoma (OR=3.4). However, the incidence of advanced proximal adenoma was increased only in those with old age (OR=11.2). Nineteen in thirty-nine (48.7%) patients with proximal colon adenoma did not have distal colon adenoma. CONCLUSIONS: Various characteristics of distal colon adenoma couldn't exactly predict the presence of synchronous proximal adenoma and a greater percentage of subjects with proximal adenoma didn't have distal adenoma. So, colonoscopy could be a standard method for colon cancer screening in Korea.

PURPOSE: To assess the spectral alteration of phosphorus metabolities in patients with liver cirrhosis andcompare energy metabolites with clinical grades using 31P MR spectra localized by two-dimensional chemical shiftimaging. MATERIALS AND METHODS: In 15 normal (control) subjects and 12 patients with liver cirrhosis, 31P MRspectroscopy was undertaken. Patients were divided into two groups, namely 'mild cirrhosis' (Child A, n=5) and'severe cirrhosis' (Child B and C, n=7) according to disease severity, as assessed by Child-Hugh's classification.In vivo 31P MR spectroscopy was performed on a 1.5-T system (Magnetom Vision; Erlangen, Germany), using a surfacecoil. Peak areas of phosphomonoester (PME), inorganic phosphate (Pi), phosphodiester (PDE), and gamma-, alpha- andbeta-ATP were defined. Peak areas of phosphorous metabolites in the spectra were expressed as values of PME/beta-ATP,PDE/beta-ATP, PME/ATP, and PME/PDE. RESULTS: The values of PME/beta-ATP, PDE/beta-ATP, PME/ATP, and PME/PDE betweencontrol subjects and patients with liver cirrhosis were significantly different. With impaired hepaticdysfunction, PME increased as PDE decreased. In patients with severe cirrhosis, the values of PME/(-ATP andPME/ATP were significantly higher than those of patients with mild cirrhosis. CONCLUSION: In patients with livercirrhosis, peak areas of PME, were significantly higher, and this might reflect the severity of hepaticdysfunction. PME/(-ATP and PME/ATP valves appear predict the severity of cirrhosis.

PURPOSE: Renal graft mass has been known as a determinant of the outcome after kidney transplantation. We evaluated the correlation between the donated kidney weight and the recipient's creatinine clearance (Ccr), the donated kidney weight and serum creatinine (Scr) as well as the correlation between the donor traits and graft function after living-donor transplantation in adults. METHODS: The weight of a donated kidney was measured just after flushing during the operative procedures, and the recipient's Scr was measured on a daily basis postoperatively. When the Scr of the recipient reached the baseline level, we collected the recipient's 24-hour urine for the Ccr calculation. Based on the measured body weight and height, body surface area (BSA) and lean body weight (LBW) were calculated. Pearson correlation analysis was carried out using the SPSS. RESULTS: The weight of donated kidney was significantly correlated with the post-transplant recipient's Ccr (P=0.022). Scr was significantly correlated with the variable of graft weight/ recipient body weight ratio (P=0.047, Pearson correlation=-0.539), graft weight/recipient BSA ratio (P=0.028, Pearson correlation=-0.438), graft weight./recipient LBW ratio (P=0.001, Pearson correlation=-0.603), donor body weight/recipient body weight ratio (P<0.001, Pearson correlation= 0.667), donorBSA/recipient BSA ratio (P<0.001, Pearson correlation=0.743), donor LBW/recipient LBW ratio (p<0.001 Pearson correlation=0.759). CONCLUSIONS: It may be appropriate to select potential living donors based on the predicted size of the kidney, especially for the recipient who will likely to have higher metabolic demands.

HCMV infection can evoke the broad spectrum of symptoms, which may be caused by the infection of responsible cell types. It is important to identify the cell types to be infected and replicated with HCMV infection for characterizing the property of HCMV infection and symptoms. Bone marrow stroma consists of heterogeneous cells, which have many cellular functions. This study was performed to verify the infectivity of HCMV to osteoblasts using the osteogenic sarcoma cell line, Saos-2, and the effect of HCMV infection to them on the cellular function. Immediate-early antigens, IE1 and IE2, were detected from 1 day postinfection (d.p.i.), and early (ppUL44) and late (gB) antigen were detected from 2 d.p.i. by the immunoperoxidase staining. All the antigens were expressed as far as observed (9 days). It was found that the virus titer in the culture supernatant and the cell pellet were 150 to 2,200 pfu/ml and 50 to 800 pfu/ml, respectively, after 4 days when the cells were infected with 2 m.o.i. Alkaline phosphatase production in Saos-2 cells infected with the different amount of HCMV was decreased to 8 to 15%, 31 to 47%, and 11 to 52% on 4, 6, and 11 d.p.i., respectively, as compared with mock-infected cells. This result suggested that HCMV could replicate in some bone marrow stromal cells and disturb the cellular function such as production of alkaline phosphatase.

OBJECTIVE: A prospective, randomized, controlled clinical study is performed to verify the effectiveness of epidural dexamethasone-soaked gelatin sponges to reduce postoperative pain following lumbar microdiscectomy. METHODS: Twenty-three patients (10 men and 13 women) undergoing lumbar microdiscectomy were included. Five pieces of gelatin sponge measuring 1 x 1 cm (Gelfoam; Pharmacia & Upjohn, Kalamazoo, MI, USA), soaked with either 5mg dexamethasone or an equal amount (2 mL) of saline, were left on the decompressed nerve root after unilateral hemilaminectomy, flavectomy and discectomy. RESULTS: Subjective visual analog scale(VAS) scores of leg pain in the dexamethasone group on the first, third and fifth postoperative days (2.5, 2.5, 1.7, respectively) were significantly lower than in the control group (5.0, 4.8, 3.6) ( P<0.05). No side effects related to the dexamethasone-soaked gelatin sponges were observed. CONCLUSION: The intraoperative application of dexamethasone-soaked gelatin sponges during lumbar microdiscectomy can provide effective postoperative analgesia without complications.
