BACKGROUND: Vitiligo is considered as an autoimmune disorder due to the generation and presence of autoantibodies directed against melanocyte antigens in the patients sera. Previous studies have revealed an increased incidence of organ-specific autoantibodies in vitiligo patients. A number of studies have demonstrated an increased frequency of thyroid autoantibodies in vitiligo patients and vitiligo is commonly seen in patients with clinical thyroid diseases. OBJECTIVE: The aim of this study is to investigate the incidence of antithyroid antibodies in vitiligo patients and to correlate the presence of these antibodies with factors such as sex, age, activity of the disease, duration of the disease and the type of vitiligo. Another aim of this study is to compare the incidence of abnormal thyroid function in those who have antithyroid antibody and those who don't. METHODS: One hundred and fifty seven vitiligo patients who visited vitiligo clinic in Samsung medical center from January of 1995 to November of 1996 were enrolled in this study. Detection and titration of antithyroid antibodies were performed by immunoradiometric assay. RESULTS: Among 157 patients tested, 17(10.8%) patients had antithyroglobulin antibodies and 10(6.4%) patients had antimicrosomal antibodies. Five patients had both antibodies. Statistically meaningful data are as follows; 1) Antimicrosomal antibody appeared less frequently in patients of childhood-onset. 2) Antithyroglobulin antibody was detected more frequently in active disease. Fifty nine out of 157 patients were examined for thyroid function. Four out of 22 patients with antithyroid antibody had abnormal thyroid function. None out of 37 patients without antithyroid antibody had abnormal thyroid function. CONCLUSION: The incidence of antithyroid antibodies according to onset age and activity is contradictory to previous reports, therefore large scaled study will be necessary to draw a conclusion.

There are many problems in treatment of intertrochanteric fractures due to osteoporosis and unstable pattern of fractures in old ages and they are different from those in young ages, for example, type of fracture, degree of osteoporosis, and general condition, ect. Anthors studied about the prognostic factors of 42 cases among 88 patients with intertrochanteric fractures, who were treated and followed up from Jan. 1982 to Dec. 1987. 1. The patients under 50 years old were mainly males(94.4%) and its chief cause of injury was traffic accident or fall down(72.2%). The cause of injury over 50 years old was slip down on ground(62.9%). 2. The osteoporosis was increased according to increased age of patients and then the unstable type of fracture was increased. In yaung patients, the unstable intertrochanteric fracture was rare despite of high violent injury. 3. The bone union of the follow-up patients was gained at average 13.8 weeks. 4. The sliding degree of lag screw was increased with unstable fracture and the incidence of metal protrusion into joint cavity was increased in the patients of eccentric fixation of lag screw into femoral head. 5. The all cases of complication were occured in osteoporotic patients over 50 years old and their causes were inadequate fixation of unstable fracture. 6. The most important factors in prognosis of intertrochanteric fractures are initial pattern of fractures, degree of osteoporosis and adequacy of reduction state(postop.).

Expandable metallic stents(EMS) were implanted in 7 patients with malignant (4 cholangio- carcinnoma, 1 pancreatic cancer, 1 ampullary carcinoma and 1 lymph node metastasis) biliary stricutres and 17 patients with benign(13 intrahepatic strictures of primary intrahepatic stone patients, 2 postoperative stricutres, 1 ampullary stenosis followed by endoscopic sphineterotomy and 1 bilioenteric anastomosis) biliary stricutures. In the fifteen patients out of 17 patients with benign biliary stricture, relief of cholangitis, improvement of liver function or loss of pruritus was observed. But in the 2 patients with.biliary cirrhosis, no clinical improvement was noted. In the malignant strictures with cholangio-carcinoma, the occlusion of EMS occurred in 3 patients and the duration of stent patency was average 2 months in those patients.

From August 1976 to February 1997, we have experienced 29 cases of rapidly destructive coxarthrosis in 23 patients who represented severe hip pain and destruction of the femoral head more than 50% within one year. The retrospective analyses of clinical, radiographic and operative findings of 2090 hips in 1534 patients, who have been diagnosed as ischemic necrosis of femoral head were performed to investigate the correlation between ischemic necrosis of the femoral head and rapidly destructive coxarthrosis. The incidence of rapidly destructive coxarthrosis was 1 % of the overall ischemic necrosis of the femoral head. The average duration of hip pain was 9 months. The average age of the patients was 56 years old and most of them were male. The cultures of synovial fluid for bacteria were negative in all cases except one case of non-pathogenic organism. But, the erythrocyte sedimentation rate and C-reactive protein were elevated. The pathologic findings were not different from the ischemic necrosis except the destruction of articular cartilage. Therefore, we concluded that rapidly destructive coxarthrosis is a subtype of ischemic necrosis of the femoral head.

Purpose: Post-fracture sleeping disorders can lead to a deterioration of mental and physical health and delay recovery to pre-fracture status. Here, an analysis was conducted to determine if sleep disturbance is a risk factor for delirium in patients older than 60 years of age with surgically treated proximal femoral fractures. Materials and Methods: This retrospective study included 316 patients with surgically treated proximal femoral fractures between January 2014 and December 2016; 33 patients were removed from analysis due to exclusion criteria. Confirmation of delirium was made by a neurologist upon consultation for cognitive impairment and sleeping disorders were confirmed by a doctor or nurse based on the Pittsburgh sleep quality index. Potential risk factors other than a sleep disorder (e.g., history of cognitive impairment, medical illness, preoperational levels of albumin and hemoglobin, transfusion) were also analyzed as variables for the development of delirium. Results: The sensitivity and specificity of a sleeping disorder as a risk factor for the development of delirium were 0.75 and 0.76, respectively; the positive and negative predictive values were 0.64 and 0.93, respectively. A sleeping disorder was significantly related to the development of the delirium (odds ratio adjusted for age, sex and body mass index was 5.78, P<0.01). In those with a history of cognitive impairment, the adjusted odds ratio for the development of delirium was 6.03 (P<0.01). Conclusion Sleeping disorders occurring after a surgically repaired proximal femoral fracture in patients 60 years of age or older could be an independent predictive factor of delirium.

PURPOSE: CTAP(CT during arterial portography) has been shown to be the most sensitive technique available for the detection of hepatic mass. But because of many false positive lesions, it is important to interpretate the findings correctly. So we tried to analyse the false positive findings in CTAP. MATERIALS AND METHODS: Materials were 47 patients that had (;TAP for the detection of hepatic lesions. After performing superior roesenteric artery (SMA) arterial portography for the detection of vascular variation, CT^P was done. 100 to 150 cc of 50% diluted nonionic contrast media was injected at 2--3ml/sec rate. Spiral CT was used with 8mm slice thickness and 8mm/sec table speed. We compared the findings of CTAP with CTHA(CT during hepatic arteriography), enhanced (;T, anglogram, US, Lipiodol CT and biopsy. RESULTS: Twenty nine false positive lesions were found. There were 11 peritumoral defects, 7 straight line signs, 5 perihilar defects, 2 periligamentous defects, 3 subcapsular defects and 1 defect by cirrhosis. CONCLUSION: When CTAP is used for the evaluation of hepatic lesion(esp, preoperative evaluation), understanding of the false positive findings and the characterization of the lesion through multi-modality approaches are needed for the correct diagnosis and the proper treatment.

Dynamic compression plate, used in the orthopedic surgery as internal fixation system, should have excellent biocompatibility, corrosion resistance, and adequate mechanical properties. The object of this research was test of its biocompatibility as compared with Osteo DCP and fabnfication of a KAIST" DCP with evaluation of its effect by animal experiment. The conclusions were follows: 1. The corrosion resistance of domestic DCP had no significant difference as compared with foreign made DCP. 2. The tissue responses to DCP were thought to be adequate. 3. The new-design DCP had less mobility at fracture site as compared with existing DCP, but there was no significant statistical differences. 4. In summary, it was concluded that KAIST DCP could be applied to the human body and it would be worth while to research the advantages of new-design DCP.

The authors reviewed angiographic findings of 96 cases of ruptured anterior communicating artery aneurysms that were operated at the Department of Neurosurgery of Hanyang University Hospital from Jan. 1986 to June 1990. The results were summarized as follows ; 1) Asymmetricity of caliber of A1 was observed in 71.9%(69/96) and which was 3 times more frequent than that of reported incidence of control group(2~23%). 2) The incidence of predominance of left A1 was 54.2%(53/96) and that of right A1 was 17.7%(17/96). Among them, predominant A1 was operated as afferent artery of aneurysm in 94.2%(65/69). 3) Of 69 cases in which a unilateral A1 showed predominance, the direction of aneurysm was opposite to the side of predominant A1 in 66.7%(46/69) and ipsilateral to the predominant A1 in only 2.9%(2/69). 4) Above findings suggest that it is desirable to approach the anterior communicating artery aneurysm via the side of predominant A1 when the direction of aneurysm is uncertain on cerebral angiogram.

This study aimed to analyze the patterns of antipsychotic prescription to patients with schizophrenia in Korea. Using the Health Insurance Review & Assessment Service-National Patients Sample (HIRA-NPS), which was a stratified sampling from the entire population under the Korean national health security system (2009), descriptive statistics for the patterns of the monopharmacy and polypharmacy, neuropsychiatric co-medications, and prescribed individual antipsychotic for patients with schizophrenia were performed. Comparisons of socioeconomic and clinical factors were performed among patients prescribed only with first- and second-generation antipsychotics. Of 126,961 patients with schizophrenia (age 18-80 yr), 13,369 were prescribed with antipsychotic monopharmacy and the rest 113,592 with polypharmacy. Two or more antipsychotics were prescribed to 31.34% of the patients. Antiparkinson medications (66.60%), anxiolytics (65.42%), mood stabilizers (36.74%), and antidepressants (25.90%) were co-medicated. Patients who were prescribed only with first-generation antipsychotics (n=26,254) were characterized by significantly older age, greater proportion of male, higher proportion of medicaid, higher total medical cost, lower self-payment cost, and higher co-medication rates of antiparkinson agents and anxiolytics than those who were prescribed only with second-generation antipsychotics (n=67,361). In this study, it has been reported substantial prescription rates of first-generation antipsychotics and antipsychotic polypharmacy and relatively small prescription rate of clozapine to patients with schizophrenia. Since this study has firstly presented the patterns of antipsychotic prescription to schizophrenic patients in Korean national population, the findings of this study can be compared with those of later investigations about this theme.

The septal extension graft is a very useful method of controlling nasal lengthening and tip projection, rotation, and shape by fixing a graft to the septum, which leads to a strong supporting structure. Enhancing graft stability is important for better long-term outcomes and minimizing complications or relapse, and even more efficient application of these methods is needed for East Asians who lack enough cartilage to be harvested in addition to possessing a weak cartilage framework. In this paper, the methods for overcoming the drawbacks of the septal extension graft, such as instability, a fixed tip, and insufficiency of cartilage, are presented, and the applications of each method for greater satisfaction with surgical outcomes are also discussed.
