Recently, Prosthetic replacement of hip was recognized as a reliable technique for the treatment of avascular necrosis of femoral head in adult. There were many reports about post-operative evaluation of functional difference between hemiarthroplasty and total hip arthroplasty and which revealed that the revision rate for the total hip arthroplasty was less compared with the femoral endoprosthesis. Also, controversy was existed between the porous coating system and bone cement fixation. In order to evaluate the functional difference among each prosthetic replacement, authors reviewed the result of 10 cases of cementless unipolar endoprosthesis (abbreviated as UE), 10 cases of cementless bipolar endoprosthesis (abbreviated as BE), and 25 cases of cementless total hip replacement arthroplasy (abbreviated as THRA), performed at Department of Orthopaedic Surgery, Soon Chun Hyang University Hospital, during the period from September, 1985 to August, 1988. The following results were obtained: 1. The incidence was higher in 6th decade in UE, THRA groups, 4th decade in BE group. 2. The average follow up of UE, BE, and THRA groups were 30.7, 15.2, and 16.9 months, respectively. 3. By radiological classification of Marcus et al., the average stages of UE, BE, and THRA were 4.9, 4.0, and 5.3respectively. 4. According to Harris hip rating system, post-op. Harris scores were increased as much as 33.1, 37.2, and 43.4 in UE, BE, and THRA groups respectivelycompared with pre-op. score. 5. In this study, the last follow up results of hip function in BE, and THRA groups were better than that evaluated at 6 months after surgery in most cases. 6. External rotation, which was one of needed motion in cross leg sitting position, was significantly influenced by the degree of excision of joint capsule, the type of replacement prosthesis, the regimen of post-op. starting exercise, and a history of previous surgical treatment. 7. Because serious complications were not developed at recent follow up, the UE, BE, and THRA groups showed insignificant difference in functional difference in prosthetic replacement.

Acute pancreatitis is occasionally caused by endoscopic treatments or radiologic interventions of the pancreatobiliary tract. However, no reports indicate that acute pancreatitis resulted from the insertion of a percutaneous transhepatic cholangiography (PTCS) catheter in the common bile duct (CBD). A 65-year-old woman visited our hospital with acute cholangitis due to about 3 cm-sized CBD stones. We planned to perform PTCS because of the large stones and altered anatomy (Billroth II). The patient was discharged after tract dilatation and insertion of a PTCS catheter in the distal CBD without manipulations of Ampulla of Vater (AOV). However, she visited the emergency room due to acute pancreatitis at three days after discharge. Computed tomography revealed upstream dilation of the main pancreatic duct following the compressed area of a large stone and catheter. Thus, we report a case that presented with acute pancreatitis induced by insertion of a PTCS catheter without manipulations of AOV.

Gallbladder (GB) cancer is asymptomatic in nature, making diagnosis and treatment difficult. The lymph node status is the strongest predictor of long-term survival for patients with GB cancer, and a complete removal of regional lymph nodes is important for patients undergoing radical resection of GB cancer. Unfortunately, lymph node metastases are common in the early stages of GB cancer. However, there have only been a few cases describing the symptoms or complications of metastatic lymph nodes in patients with GB cancer. Although hemoperitoneum caused by metastatic lymph nodes can occur with several cancers, it is very rare. To the best of our knowledge, hemoperitoneum from spontaneous ruptures of metastatic lymph nodes with GB cancer has not yet been reported. Herein, we describe such a case in a patient newly diagnosed with GB cancer.

PURPOSE: To evaluate the association between multidrug resistance (MDR) gene and prognosis of acute lymphoblastic leukemia (ALL), several parameters were compared according to the expression status of MDR associated P-glycoprotein. METHODS: 40 bone marrow samples from 36 children of acute lymphoblastic leukemia were analyzed with immunohistochemical stain by C219 monoclonal antibody. RESULTS: 1) The expression of MDR associated P-glycoprotein was positive in 47% at the time of initial diagnosis & 66.7% at relapse. 2) There are no stastical difference between two groups in complete remission rate, relapse rate, mean 2 years survival rate. 3) Event free survival duration was 11.3 months (+/-8.5 months) in P-glycoprotein positive group, while 20 months (+/-7.3months) in P-glycoprotein negative group (P<0.05). 4) There are no stastical difference between two groups in the mean age, sex ratio, initial WBC and immunophenotype of subjects. CONCLUSION: These results suggested the possibility of adopting MDR associated P-glycoprotein in the design of therapeutic regimen and prognostification of childhood acute lymphoblastic leukemia. However, a prospective, randomized study incorporating a larger population should precede before a firm conclusion of significance would draw regarding the prognostic and the therapeutic implication of P-glycoprotein in childhood acute lymphoblastic leukemia.

OBJECTIVE: We aimed to introduce our method involving prepuncture ultrasound scan for cannulation of the common femoral artery (CFA) during transfemoral cerebral angiography (TFCA), and to assess the clinical and radiological outcomes. MATERIAL AND METHODS: Our study included 90 patients who underwent prepuncture ultrasound examination of the inguinal area for TFCA between April 2015 and June 2015. Prior to skin preparation and draping of the inguinal area, we identified the CFA and its bifurcation using ultrasound. Based on the ultrasound findings, we marked cruciate lines in the inguinal area. Thereafter, we inserted a puncture needle at the interface between the horizontal and vertical lines at a 30–45° angle, simultaneously palpating the pulsation of the femoral artery. After TFCA was completed, femoral artery angiography was performed in the anteroposterior and oblique directions. Clinical and radiological parameters, including CFA cannulation, the ultrasound scan time, the first pass success rate, the time required for the passage of the wire, and complications, were evaluated. RESULTS: The mean ultrasound scan time of the CFA and its bifurcation was 72.6 seconds, and the mean time between administration of local anesthesia and wire passage was 67.44 seconds. The first pass success rate was 77.8% (70/90 patients), and the CFA puncture rate was 98.8% (89/90 patients). Although minor complications were noted in 7 patients, no patient reported serious complications (a large hematoma [≥ 5 cm], pseudoaneurysms, dissection, and/or a retroperitoneal hematoma.) CONCLUSION: Prepuncture ultrasound examination might be a simple, safe, and accurate technique for cannulation of the CFA during TFCA.

OBJECTIVE: The purpose of this study was to evaluate the physicochemical properties and cytocompatibility of microporous, spherical biphasic calcium phosphate(BCP) ceramics with a 60/40 hydroxyapatite/beta-tricalcium phosphate weight ratio for application as a bone graft substitute. MATERIALS AND METHODS: Microporous, spherical BCP granules(MGSB) were prepared and their basic characteristics were compared with commercially available BCP(MBCP; Biomatlante, France) and deproteinized bovine bone mineral(Bio-Oss; Geistlich-Pharma, Switzerland, BBP; Oscotec, Korea). Their physicochemical properties were evaluated by scanning electron microscopy, X-ray diffractometry, Fourier-transform infrared spectroscopy, inductively coupled plasma atomic emission spectrometer, and Brunauer-Emmett-Teller method. Cell viability and proliferation of MC3T3-E1 cells on different graft materials were evaluated. RESULTS: MGSB granules showed a chemical composition and crystallinity similar with those in MBCP, they showed surface structure characteristic of three dimensionally, well-interconnected micropores. The results of MTT assay showed increases in cell viablity with increasing incubation times. At 4d of incubation, MGSB, MBCP and BBP showed similar values in optical density, but Bio-Oss exhibited significantly lower optical density compared to other bone substitutes(p < 0.05). MGSB showed significantly greater cell number compared to other bone substitutes at 3, 5, and 7d of incubation(p < 0.05), which were similar with those in polystyrene culture plates. CONCLUSION: These results indicated the suitable physicochemical properties of MGSB granules for application as an effective bone graft substitute, which provided compatible environment for osteoblast cell growth. However, further detailed studies are needed to confirm its biological effects on bone formation in vivo.

BACKGROUND: The studies on prediction equations of pulmonary function parameters for adults in Korea have been performed in a reference population mainly consisted of young and middle ages. So they included a relatively few elderly who conducted pulmonary function test frequently in clinic. We established prediction equations of pulmonary function parameters for healthy adults over 50 years old in rural area and compared this results with those of other studies. Therefore we attempted to consider normative values of pulmonary function tests for elderly in Korea. METHOD: Five hundred thirty-three women and men over 50 years old in rural area were participated. A "healthy" subgroup of 110 women and 32 men were identified by excluding those who had conditions that negatively influenced pulmonary function. We derived prediction equations for FVC, FEV1, and FEV1% by multiple linear regression method from their age, heights and weights in each sex. RESULTS: Prediction equations for FVC and FEV1 in each sex were derived as follows Male; FVC (L) = 0.02488Height(cm) - 0.0269Age(years) + 0.493 FEV1(L) = 0.01874Weight(kg) - 0.0282Age(years) + 2.906 Female; FVC(L) = 0.02160Height(cm) - 0.0192Age(years) - 0.0125 FEV1 (L) = 0.01720Height(cm) - 0.0194Age(years) + 0.3890 Prediction equations for FEV1 % were not derived because FEV1 % didn't have statistically significant terms. Comparing Predicted values that were calculated by substitution into the equations of various studies of mean values of age, heights and weights from this study, FVC and FEV1 values in men of this study were lower than those of other studies. In women, FVC and VEV1 values of this study were as similar as or lower than those of the study conducted for healthy elderly blacks in U.S.A respectively. CONCLUSION: We have got prediction equations of pulmonary function parameters which were driven from forced expiratory spirogram in adults over 50 years old in rural area. Predicted values of this study were lower than those of other studies which were conducted in Korea. So we consider that the study for spirometry reference values for elderly Korean using the method compatible with ATS recommendation need to be conducted more frequently forward.
