PURPOSE: We reviewed 13 cases of pancreatic pseudocysts treated by percutaneous catheter drainage to determine the value and effectiveness of the procedure. MATERIALS AND METHODS: Sixteen pancreatic pseudocysts(nine infected, seven noninfected) were drained in 13 patients. Access routes were determined by images on CT scan and procedures were performed under fiuoroscopic guidance. Ultrasonogram was used as a guide for drainage when there were bowel loops near the access routes. Various access routes were used for catheter drainage:transperitoneal (10), retroperitoneal (3), transsplenic (2) transhepatic (1). RESULTS: Percutaneous catheter drainage cured 15 of 16 pancreatic pseudocysts(93.8%). No recurrance was encountered in the clinical follow-up of 7 to 69 months(mean 35 months). The mean duration of drainage was 29 days(infected, 24 days; noninfected, 39 days). Five pseudocysts(31%) were communicated with pancreatic duct The mean duration of drainage in these cases was 38 days. Spontaneous of the pancreatic pseudocysts to the gastrointestinal tract was occurred in 3 pseudocysts. Mean duration of drainage in pseudocysts with fistulas was 19 days. CONCLUSION: Percutaneous cather drainage is a safe and effective front-line treatment method in most pancreatic pseudocysts if drainage is done with a adequate follow-up and catheter care.

BACKGROUND AND OBJECTIVES: N-cadherin is known to be expressed in neuroectodermal tissue such as central nervous system and various mesodermal origin tissues such as kidney and heart. We investigated N-cadherin expression in the endocardial cushion in developing rat heart by immunohistochemical method. MATERIALS AND METHOD: Fetal rat hearts at the 11th, 13th, 15th, 17th, and 19th day of gestation and the 1st day neonatal rat heart were used. Hematoxylin and eosin stain was performed for normal cardiogenesis, and immunohistochemistry was performed for the expression of N-cadherin in interventricular septum(IVS) during cardiogenesis in rat. RESULTS: Ventricular wall and membranous part of the IVS showed positive reaction with anti-N-cadherin at the 11th day of gestation. Membranous part of IVS was begun to show tracely positive reaction at the 15th day of gestation, and thereafter the immunoreactivity was increased with maturation. At the 17th day of gestation mesenchymal cells in membranous muscular part of the IVS showed positive reaction. The similar immunoreactivity of membranous and muscular parts of IVS were shown at the 19th day of gestation. CONCLUSION: As the immunoreaction of mesenchymal cells in the membraneous part of IVS to anti-N-cadherin was increased with time, it is suggested that mesenchymal cells in membranous part of IVS were differentiated into the cardiomyocytes.

Osteoporosis has recently been recognized as a major health problem in the elderly population. The disorder is manifested as a loss of bone mass accompanied by structural alteration of bone and increased incidence of fracture. Mandible also may be affected. So, I evaluated panoramic views of 66 postmenopausal women for finding the possibility of useful diagnostic mandibular parmeters of osteoporosis. To know the correlationship between skeleton and mandible, the average of the bone mineral density of lumbar from 2nd to 4th by the dual energy X-ray absorptiometry(DEXA, LUNAR DPZ. USA), and age and mandibular parameters, that is, the number of residual teeth, alveolar ridge resorption ratio, panoramic mandibular index (PMI), mandibular cortical width (MCW), angular cortical thickness (ACT), ramus cortical thickness (RCT), morphology of mandibular inferior cortical (MIC) were compared. And I divided the all tested women to the osteoporotic group and non-osteoporotic group by the use of T-score-2.0, which was derived from skeletal bone mineral density (BMD). To find the correlationship of the each group with mandibular parameters, t-test and discriminant analysis were done. The results of the t-test were that all parameters were highly related with 2 groups (p<0.05). Especially ACT, MIC, age have had even higher correlationship than others (p<0.001). The results of the discriminant analysis by the use of these ACT, MIC and age were that the discriminant function was Z =-2.973+(-1.447)x(ACT)+1.131x(MIC score)+(0.052)x(age), the cutting score was 0.257 and the classification accuracy was 84.8%. Therefore I suggest that the consideration of the angular cortical thickness (ACT), the age of patient and the morphology of mandibular inferior cortical(MIC) may help find the osteoporosis.

Five cases of cerebral arteriovenous malformation(AVM) are presented, which underwent total extirpation using the operating microscope. The following are considerations which favor the total extirpation of AVM and the advantages of using the operating microscope, including the rationale for non-use of hypotensive anesthesia or mannitolization which is commonly used in intracranial aneurysm surgery: 1) Relatively small sized AVMs are found to show a high rate of large intracerebral hematoma, including that the degree of bleeding from the malformed vessels is not related to the size of the AVM. 2) The operating microscope facilitates the following procedures: a) determination of the extent of the malformed vessels. b) clipping feeders. c) identification of red vein and laminar flow. d) preservation of normal brain tissue.

Percutaenous transhepatic biliary drainage (PTBD) is widely used to control cholangitis, sepsis, or jaundice caused by biliary tree obstruction. The PTBD tract can be used in percutaneous biliary stone extraction in pre-or post-operative state when ERCP is failed or operation is contraindicated. We performed 16 cases of percutaneous transhepatic biliary stone removal. Locations of biliay stones are combined intrahepatic and extrahepatic in 8 cases (50%), only extrahepati in 7 cases (44%), and only intrahepatic in 1 case (6%). The number of stones was single in 6 cases and multiple in 10 cases. Over all success rate was 81% (13/16), 93% (14/15) in extrahepatic stones and 78% (7/9) in intrahepatic stones. In 5 of 6 cases, complete stone removal was impossible due to marked tortuosity of T-tube tract or peripherally located stones, complete removal of biliary stones was achieved via a new PTBD tract. No significant pre-or post-procedure complication was occured. Percutaneous removal of biliary stones via PTBD tract is an effective and safe alternative method in difficult cases in the menagement of biliary tract stones.
