Background/Aims: Pancreatitis is one of the major complications of ERCP. The purpose of this study is to evaluate the incidence rate and risk factors of ERCP- induced pancreatitis. Method: We analysed 99 consecutive patients(45 males and 44 females) undergoing ERCP from March to September, 1994. The level of serum amylase was measured and clinical assessment of pancreatitis was performed before, 24 hour, 48 hour, and 72 hour after ERCP. We defined clidical pancreatitis as combination of elevated amylase level over 2 days with abdomial pain and tenderness.(continue..)

Undifferentiated sarcoma of the liver is a highly malignant neoplasm that occurs almost exclusively in children. We present a case of adult undifferentiated sarcoma in a 33-year-old man. The neoplasm was typically hypovascular on hepatic angiography and a globular, cystic and mucoid mass separated from the adjacent liver by a psedocapsule was removed from the left lobe of the liver. Necrosis and hemorrhage were found. Microscopically the neoplasm consisted of myxoid and cellular areas and the basic neoplastic cells were stellate cells showing variable degree of anaplasia and pleomorphism. Eosinophilic globules were PAS-positive and immunohistochemically negative for alpha-fetoprotein. Extramedullary hematopoiesis was present and normal-appearing bile ducts and hepatic cell cords were noted.

We report a case of hyperkeratosis of the nipple and areola occuing in 33 year old woman. She did not have a history of endocriruipathy, horrnonal therapy and other ceatoses, so this case seems to be the nevoid form by Levy-Franckel classification. Interestingly, however the lesion which had developed before marriage suddenly aggr avated during pregnancy. This may be a unique feature which has not been reported elsewhere. Histapathologic findings are compatible with breviously reported eases. There was no response to topical steroid and retinoic acid treatrnent.

PURPOSE: This study was done to define nursing behavior in neonatal intensive care units so as to estimate resource-based relative value-. METHOD: Participating in this study were 292 nurses in neonatal intensive care units. The study surveyed physical and mental labor, stress and time involved in nursing work. Tool used in this study was a nursing labor per relative value tool. For analyzes, the relative value of each nursing behavior was calculated, where the mean value of the three components, labor intensity and component-by-component explanatory power were in percentage terms. RESULTS: 1. Nursing behaviors in neonatal intensive care unit were classified and defined at three levels: 5 main domains, 17 mid-domains, and 42 small domains. 2. The per component explanatory power of intensity involved in nursing labor showed physical effort to be 32.45%, mental 32.86%, and stress 34.69%. 3. The reliability of nursing labor factors was very strong, Cronbach's alpha value of 0.96. CONCLUSION: In this research, which is a first in defining nursing behavior in neonatal intensive care units, individual nursing behavior were broken down using resource-based relative value for nursing cost, and each nursing behavior was successfully translated to a numerical value.

Lipocortin represents a family of similar Ca++ depentent phospholipid-binding proteins capable of blocking the activity of phospholipase A2 (PLA2) in vitro. Generally, these proteins are believed to inhibit the release of arachidonic acid from photopholipids and the formation of lipid mediators such as prostaglandin, leukotriene, and platelet activating factor. Lipocortin 1, initially identified as a glucocorticoid- responsive protein in macrophages and neutrophils has been implicated in transmembrane signal transduction during growth factor-mediated cell proliferation and transformation. To define the synthesis and its regulation, we investigated the expression of lipocortin 1 in both the mRNA and protein level in U937 cell line in the presence of several differentiation factors. The results were as follows. 1. The expression of lipocortin 1 and its mRNA was increased during TPA-induced differentiation of U937 cells to maximum of 2-fold and 5-fold respectively. Both the protein and mRNA levels decreased after 48 hours. 2. With the treatment with IFN-gamma, the expression of CD16 was increased. However, the protein and mRNA levels of lipocortin 1 were, not changed significantly. 3. Neither the dexamethasone or hydrocortisone have any effects on the expression of lipocortin 1 in both TPA-differentiated and undifferentiated U937 cells. The results from this study would give a light on defining the functional role of lipocortin 1 in macro-moncycle cell lineage and possibly some informative clues for the pathogenic mechanisms of the inflammatory diseases.

PURPOSE: To compare the functional and radiographic results of the treatment in unstable intra-articular fractures of distal radius by closed reduction and external fixation versus open reduction and internal fixation. MATERIALS AND METHODS: Forty cases of unstable intra-articular fractures of distal radius were treated either by application of closed reduction and external fixation (CREF) or by open reduction and internal fixation (ORIF) between March 1989 and June 1997. They were followed up for more than one year. To assess the functional results, we used Green and O' Brien' s score system and for the radiographic results, measured volar tilt, radial inclination and radial length. RESULT: In functional results, excellent to good results were obtained in 19 cases (76%) in the CREF group and 10 cases (80%) in the ORIF group, and the average score was 81.4 and 82.8 by the Green and O' Brien' s score system. In radiographic results, mean loss of volar tilt, radial inclination and radial length were 1.4 degree (13.4%), 2.0 degree (9.0%), 1.3 mm (10.3%) in the CREF group and 1.2 degree (10.8%), 1.6 degree (6.1%) and 1.2 mm (11.5%) in the ORIF group on last follow-up radiographs. There was no evidence of statistical difference between two groups in functional and radiographic results (P>0.05). CONCLUSIONS: If an appropriate operative method is selected according to the presence of several properties, including the pattern of fracture, the general condition and activity of patient and the degree of soft tissue injury, the two operative managements are considered useful to restoring articular congruity and alignment and to allow early postoperative range of motion exercise

The pinching motion is thought to be one of fundamental hand functions, the power of which has been quantified by measuring it isometrically with variously devised pinch-meters. The present authors describe the investigations on the pinching power of 350 healthy persons, 200 male and 150 female Koreans, by the use of Preston Pinch Gauge. Six kinds of pinch were chosen: (1) thumb index finger tip pinch (1-2TP), (2) thumb-middle finger tip pinch (1-3TP), (3) thumb-index finger pulp pinch (1-2PP), (4) thumb-middle finger pulp pinch (1-3PP), (5) thumb-index-middle finger pulp pinch (3PP), (6) key pinch (KP), which were classified again into 19 kinds according to the shape of thumb, index, middle, or other fingers during each pinch. We describe those as principal type, hyperextension-flexion type, hyperextension type and other type into four. It should be justified to calculate the mean normal value of principal type pinching power in Korean. Principal type of pinch involves 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP, as to Hyperextension type of 1-2PP, 1-3PP, 3PP and KP. Other type of pinch involving 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP is different from Principal type simply because of the shape of nonjoining fingers during pinch. Generally, the pinching power of Principal type was clearly highest among the four types except for pulp pinches.

Voluntary habitual dislocation of the hip is very rarely reported in children, and only 13 cases have been reported in the literature. We add a new case in a 5 year old boy. The boy did not have previous history of trauma, skeletal and/or soft tissue anomalies, nor known connective disease. He was treated by intertrochanteric varusinward rotation osteotomy of the affected hip on February 25, 1985 and was followed until January 11, 1993. Postoperative convalescence was uneventfully successful, and the hip developed well without any obvious dysplasia at the latest follow-up.
