Two isotypes of nm23 gene have been reported as multifunctional genes as well as CD44 gene. In tumor, both of genes, one isotype of human nm23, nm23-H1 and splice variants of surface glycoprotein CD44[CD44 v8-10], are correlated with tumor growth and metatastic potential[Keim et al., 1992 ; Dall et al., 1995]. However, the correlation of expression between these genes in tumor was not reported. In this immunohistochemical study on skin cancers, basal cell carcinoma, squamous cell carcinoma, and malignant melanoma, we intended to clarify the differences of expression on the basis of origins of skin tumors, basal cell, prickle cell, melanin producing cell, and compare the alterations of expressions between two genes in each tumor, respectively. The conclusion of this comparison is that relative parallel alteration in expressions between nm23-H1/NDP kinase and CD44 v8-10 was observed in basal cell carcinoma and malignant melanoma with inverse relation in differentiation. In squamous carcinoma, the expressions of two genes were much associated with differentiation. On the periphery of tumor, very low level of nm23-H1 protein and high level of CD44 v8-10 protein were detected.

PURPOSE: Pilomatrixoma is a benign, usually asymptomatic tumor. It presents clinically as a solitary superficial subcutaneous nodule measuring between 0.5 cm and 5 cm in diameter on the head or upper extremeties and has not been reported after skin graft. The objective of this article is to report our experience in treating pilomatrixoma which occurred after split thickness skin graft on the lower extremity. METHODS: A 56-year-old female was treated in August 2005 with a 0.5 X 0.5 cm firm subcutaneous nodule at recipient site of split thickness skin graft on the left medial thigh. The tumor was successfully removed by complete excision and histologic examination was followed. RESULTS: The diagnosis was pilomatrixoma which was characterized by a dual population of proliferating basophilic cells and diagnostic shadow cells. CONCLUSION: The tumor was successfully treated by complete resection. The authors report this very rare case of pilomatrixoma which occurred at recipient site of split thickness skin graft.

M-mode, pulsed Doppler and Doppler color flow mapping, in addition to two-dimensional echocardiography, have greatly improved imaging of the fetal heart through identification of abnormal cardiac anatomy and rhythm in utero. The early detection of cardiac disturbance in utero permits alteration in obstetric management such as delivery in a high-risk center for optimal neonatal care and/or decision in optimal delivery time. We report two cases of the neonatal arrhy-thmia which were observed by fetal echocardiography. In the first case, female baby showed neonatal arrhythmias including tachycardia and brady-cardia until 3 days after birth, and then turned to bradyarrhythmia due to non-conducted atrial bigeminy. These events lead us to review the fetal echocardiographs of the patient carefully. Premature atrial contractions were observed in her fetal echocardiography. At 2 months after birth, the patient's electrocardiogram showed normal sinus rhythm. Severe neonatal bradycardia of the second case was due to congenital complete heart block, identified clearly by electrocardiogram after birth. This case also showed complete heart block in her fetal echocardiography. After insertion of the temporary pacemaker, cardiomegaly was improved. Both the neonate and the mother had positive anti-SSA/Ro autoantibody. But any other symptoms and signs of neonatal lupus did not appear in the neonate. Patient's mother also did not show any symptoms and signs of systemic lupus erythematosus. Since the prognosis depends upon the cause of bradyarrhythmia in fetus and neonates, differential diagnosis is important in obstetric management and optimal neonatal treatment.

We performed ERCP manometry of Sphincter of Oddi(SO) before and after endoscopic sphincterotomy(EST) for evaluation of the effect af EST on the SO. The subjects were postcholecystectomized common bile duct stone patients(n=l2) and EST was performed by major incision. The pressure gradient between common bile duct and duodenum before EST (8.6 + 3.9 mmHg) decreased significantly after EST(2.4 +1.7 mmHg). The length of SO before EST(8.8 + 0.8mmHg) decreased significantly after EST(2.5 + 0.8mm). But in each patient, the pressure gradient between common bile duct and duodenum remained in spite of the major incision. In conclusion, EST alters the function of the sphincter of the Oddi, but does not destroy its all protective function. The positive pressure in the bile duct is preserved in contrast to the absolute loss of pressure following surgical transduodenal sphincteroplasty.

From July 1989 to August 1991, we performed 146 cases of endoscopic sphincterotomy(EST). In our series, 9 early complications occurred in 146 cases(morbidity rate: 6.2%), and no fatalities were recognized(mortality rate:0). Four cases with late complications consisted of 2 cases of acute cholecystitis, one case of chalaagitis and restenosis. There were 36 with the gallbladder with stone(11 cases) or without stone(25 cases). Two cases with chalecystitis after EST occurred in the patients with gallbladder stones. EST gives the sufficient result in diagnosis and treatment for various disease of biliary tract. Furthermore, EST was found to be a safe procedure from low rates of complications and fatalities.

PURPOSE: To evaluate the diagnostic role of a three-dimensional MR cholangiopancreatography(MRCP) over endoscopic retrograde cholangio- pancreatography(ERCP) in various extrah-epatic biliary disease. MATERIALS AND METHODS: MRCP and ERCP were performed in 45 consecutive patients with suspected extrahepatic biliary diseases. MRCP was obtained using a reverse fast imaging with a steady-state free precession (reverse FISP : PSIF) sequences, and then images were reconstructed by standard MIP algorithm. The predictability of biliary dilatation and level of obstruction of MRCP was evaluated using ERCP as a gold standard. The accuracy distinguishing malignant from benign lesions, and overall diagnostic accuracy were compared between MRCP and ERCP. RESULTS: The sensitivity, specificity and accuracy of MRCP in predicting biliary dilatation were 94.6%, 75.0% and 91.1%, respectively. The level of obstruction was accurate in 87.0% with MRCP. The sensitivity, specificity and accuracy MRCP and ERCP in distinguishing malignant from benign lesions were 76.2%, 87.5% and 82.2% and 71.4%, 83.3% and 77.8%, respectively. The overall diagnostic accuracy was 60.0% with MRCP and 55.6% with ERCP. CONCLUSION: 3D MRCP shows a good diagnostic value compared to that of ERCP, and can replace a ERCP.
