OBJECTIVE: Base on clinical practice, the authors report a case of tardive dyskinesia arising during the course of treatment with resperidal. METHODS: This article was review and analysis of a case on risperidone-induced tardive dyskinea. RESULTS: Mrs K, a 51-year-old women with a 1-year history of schizophrenic disorder, gradually developed tardive dyskinetic movement of the mouth, lip, and tongue over a 4 month period(From July 1996 to June 1997) while taking risperidone. Initially she was treated with haloperidol and alprazolam. However, the haloperidol was subsequently discontinued because of EPS developed. From 11th March 1997, she was observed to have a severe form of tardive dyskinesia involving her tongue, lip, and mouth. After risperidone was withdrawn at 9th May 1997, her tardive dyskinetic movement was disappeared. CONCLUSIONS: This is, to our knowledge, the first report of the onset of tardive dyskinesia in a patient taking risperidone. However, additional controlled studies of specific questions are needed ; e.g., the dose-response curves for produce tardive dyskinesia and the mechanism of producing risperidone-induced tardive dyskinea and so on.

Epidermoid cysts occur rarely on the palms and soles, where hair is not present. These cysts have long been assumed to arise from traumatic implantation of epidermal fragment, but the pathogenesis is still controversial. Recently, with microscopic findings, immunohistochemical features, and molecular studies, the epidermoid cysts of the sole may be induced by the human papillomavirus. We report two cases of epidermoid cysts of the sole with the discussion of the pathogenesis.

Primary ampullary carcinoma is one of rare gastrointestinal malignancies which can be diagnosed by ERCP and endoscopic biopsy. However, sometimes it is difficult to comfirm the diagnosis when the tumor is not exposed out of orifice of ampulla. Recently, we diagnosed early stage ampullary carcinoma using endoscopic sphincetrotomy for the exposure of tumor in 54 year old woman ia whom ERCP revealed rather impacted stone like filling defect in distal common bile duct. we describe a case of papillary adenocarcinoma of the ampulla of Vater diagnosed by edoscopic sphincterotomy.

BACKGROUND/AIMS: The endoscopic mucosal resection has now been adopted for a useful modality in both curative therapy and accurate diagnosis of early gastric cancer. A retrospective study was done to evaluate the indication and the limitation of endoscopic mucosal resection of early gastric cancer. METHODS: We studied 20 cases of early gastric cancer treated by endoscopic mucosal resection in Chungnam National University Hospital from November, 1995 to July, 1997. RESULTS: 1) The size affected the curability: 83. 3% of lesions less than 2 cm and 50. 0% of those larger than 2 cm were resected completely. 2) The depth of cancer invasion affected the curability: 87. 5% of lesion confined to mucosa were resected completely, while all of submucosal cancers were resected incompletely. 3) Among fourteen cases resected completely, three cases of lesions larger than 2 cm were residual cancer and two of those less than 2 cm were recurred locally. CONCLUSIONS: To be a curative therapy by endoscopic mucosal resection of early gastric cancer, we think that careful selection of the lesion, that is lesion less than 2cm and confined to mucosa, is necessary

PURPOSE: To establish the incidence of deep vein thrombosis among Koreans after primary total hip arthroplasty and the usefulness of color doppler ultrasonography for routine noninvasive screening for deep vein thrombosis. MATERIALS AND METHODS: We performed prospective, randomized routine venography and color doppler ultrasonography before and after operation in a consecutive series of 89 primary total hip arthroplasty in which no form of prophylaxis was used. RESULTS: Of the 89 cases, eleven (12.4%) were found to have deep vein thrombosis (three proximal veins and eight distal veins) by bilateral venography. Most of the thromboses except two were asymptomatic. No patient had a symptomatic pulmonary embolism. Statistical analysis of risk factors, age, gender, weight, height, fixation method, and duration of operation time, were performed and there was no statistical difference (P>0.05). The reliability of color doppler ultrasonography for detection of deep vein thrombosis was demonstrated. CONCLUSIONS: We found insufficient evidence to recommend routine thromboprophylaxis in primary total hip arthroplasty among Koreans. The authors recommend that routine bilateral color doppler ultrasonography screening be considered after primary total hip arthroplasty for detection of deep vein thrombosis

The methods available for arthroscopic debridement vary widely in cost and efficiency. The use of laser treatment is growing rapidly with advantages of production of smooth surface and avoidance of direct contact. Nevertheless, growing attention is directed to the negative side effects of laser-controlled cartilage ablation, especially to the depth effects of the various lasers on which various scientific studies have focused. The purpose of this study is to evaluate the thermal side effects of Ho: YAG laser and Excimer laser on human articular cartilage hy histological analysis. Sixteen human articular cartilages were obtained during total knee arthroplasty for patients with advanced degenerative arthritis. Three craters, 1cm in diameter, were created on each articular cartilage by shaver, Holmium: YAG laser and Excimer laser in the saline medium. These total 48 craters were prepared to tissue specimen by paraffin blocks and stained with Hematoxylin-Eosin(HE) and Massons trichrome. Under the light microscope, we analysed extents of thermal necrosis and thermal change in craters. Also some specimens were fixed by 2.5% glutaraldehyde and ohserved in changes of three different methods under scanning electron microscope. We report the results as follow: 1. The average times to making one crater were 25 seconds in shaver, 33 seconds in Holmium: YAG laser, and 65 seconds in Excimer laser respecti vely. 2. In gross inspection, the most smoothing surface of crater was seen on the specimens of Excimer laser. 3. In histological findings, thermal necrosis on hematoxylin and eosin sections was not noted after shaver use, whereas seen average of 243.8+/-159.6micrometer in Molmium: YAC laser and 36.6+/-17.1micrometer in Excimer laser(p=0.000). Thermal change on trichrome-stained sections was not noted after shaver use, hut showed average of 372.1 +/-203.1micrometer in Holmium: YAG laser and 76.0+/-47. Imicrometer in Excimer laser(p=0.000). 4. In scanning electron micrograph, coagulation of collagen fiher in the matrix was ohserved, with less extents in Excimer than Holmium: YAG laser. In conclusion, Excimer laser was superior to Holmium: YAG laser in terms of thermal necrosis and precision, whereas Holmium: YAG laser was more effective due to rapid time for procedure. To minimize the thermal necrosis during laser chondroplasty, we suggest it is desirable to less energy and reduce exposure time to laser beam on the articular surface.

PURPOSE: The purpose of this study was to investigate the radiologic and serologic factors related to postoperative union using intramedullary (IM) internal fixation in atypical femoral fractures (AFF), which are closely related to bisphosphonates (BPs) for osteoporosis. MATERIALS AND METHODS: From February 2008 to December 2016, 65 patients (71 cases) who had undergone IM nail fixation after diagnosis of AFF were enrolled in this study. Patients were divided into group A, who experienced union within 6 months and group B, who did not experience union within 6 months. They were evaluated for duration of BPs use, radiologic factors and serological factors. RESULTS: The mean duration of BPs use was 6.17 years in group A and 8.24 years in group B (p=0.039). In the subtrochanteric area, there were 14 cases (27.5%) in group A and 14 cases (70.0%) in group B. In the femoral shaft, there were 37 cases (72.5%) in group A and 6 cases (30.0%) in group B (p=0.001). On the preoperative, the flexion in the coronal plane was 5.9° (2.1°–9.2°) in group A and 8.0° (3.1°–12.1°) in group B (p=0.041). On the postoperative, conversion to valgus was 15 cases (29.4%), 8 cases (40.0%); conversion to neutral was 34 cases (66.7%) and 8 cases (40.0%); conversion to varus was 2 cases (3.9%) and 4 cases (20.0%), each (p=0.037). The fracture site gap was 1.5 mm (0–2.9 mm) on the front side and 1.2 mm (0–2.2 mm) on lateral side and 2.2 mm (0.9–4.7 mm) and 1.9 mm (0.5–3.5 mm), each (p=0.042, p=0.049). Among serological factors, there was no significant difference between the two groups. CONCLUSION: Factors adversely affecting the union should be recognized before surgery, such as longterm BPs use or a severe degree of bending of the femur in the coronal plane. During surgery, proper reduction and spacing of the fracture site on the coronal plane should allow adequate reduction of the anterior and posterior surfaces. Obtaining anatomic reduction would be most beneficial for union, but if that is not possible, obtaining congenital valgus rather than varus on the coronal plane may be helpful for union.
