We report a case who has been diagnosed as lipodytrophia centrifugalis abdomialis juvenilis. The patient was a 9 year-old girl. At the age of 4 years, these well-defined, depressed lesions appeared in both ing-uinal areas and gradually spread to the labia major, the abdomen and both flank areas and, by 9 years, had reached lower portion of the chest. Biopsy specimen from the depressed lesion showed absence of the subcutsneous fat. The epidermal appendage were well preserved. There were lympho-histiocytic infiltrations around the blood vessels in the upper dermis.

The number of non-specific urethritis(NSU) is exceeding more and more that of Gonorrhea in developed nations and sorne of the developing countries especially in our country. Chlamydia trachomatis and Ureaplasma urealyticum, which are the most suspected etiologic agents of NSU, are sensitive to either tetracycline or erythromycin. We compared the effect of oral tetracycline to erythromycin in the treatment of male NSU. The subjects were 524 male patients with NSU at the VD clinic of the Choong Ku Public Health Center in Seoul during 16 months period from January 1980 to April 1981, The diagnostic criterial of NSU were; 1) Five or PMN/HPF in Gram-stained smears of urethral dischage of centrifuged sediment of urine, 2) no Gram-negative intracellular diplococci in Gram stained smears of urethral discharge, 3) no growth of Neisseria gonorrheae in Thayer-Martin media, 4) no Trichomonas vaginalis or Candida albicans in centrifuged sediment of urine.

We had given the Anti-PGL-1 ELISA test to the 235 leprosy patients in our Hospital from July 1999 to Aug 2000. There are 48 patients(20.4%) who are over 200 PGL-1 Ab score and 11 patients(4.7%) who are over 500. The patients who are over 500 of PGL-1 Ab score are all lepromatous leprosy and they have been treated from 5 to 49 years. Two patients among them are positive patients and 9 patients are to be observed only I think that they need to be followed up and if the score of Ab has incresed. We suspect that those patients will become active.

It is well known that M. leprae involves peripheral nerves, but it is a few known that M. leprae involves craninal nerves. I experienced one case of relapsed leprosy accompanied by multiple cranial nerve palsies. Revealed symptoms are to involve trigeminal nerve (V). facial nerve (VII), vestibular nerve (VIII), glossopharyngeal nerve (IX), vagus nerve (X). It is not effect to treat with corticosteroid, but is good effect to treat with MDT(multiple drug therapy)

Regular hemodialysis has been established as a way of treatment for end stage renal failure. In adults, hemodialysis 5 hours each time, three times weekly with one square meter hemodialyzer is now widely accepted as a standard, and there are many reports on long term follow up studies. Quite a large difference are present, however, in our community mainly originated from patient's poor compliance in frequent dialysis with short interdialysis interval. The author analyzed 200 cases of chronic renal failure who have received hemodialysis treatments during the 5 year period from July 1976 to June 1981 at the hemodialysis unit of the hanyang University Hospital and the following results are obtained; 1. Actual one year survival rate was much higher in thrice(87.1%) than one(35.1%) or twice(54.1%) weekly dialysis. 2. Long term(more than 6 months) complications were also more frequent in once(85.7%) or twice(70.2%) weekly treatments than in thrice(22.2%). The predominant complications were congestive heart failure, pericarditis, and infections. 3. Those who recieved three times weekly dialysis had better rehabilitation grades than the patients groups of twice or once weekly treatment. 4. Of peridialysis distressful symptoms, nausea, vomiting dizziness were less frequent in the group three times a week dialysis. In contrast, headache, hypotension, muscle cramps, and weakness were not significantly related with frequency of hemodialysis. 5. Those who voided a large amount of urine output had better survival and less frequent requirement of blood transfusions. 6. Main causes of death were due to patient poor compliance, hyperkalemia and cerebrovascular acidents. 7. Economic problems were the major cause of dialysis interruption.

Finite element analyses were performed to study effects on stress distribution generated in jaw bone for various shapes of dental implants: plateau type, plateau with small radius of curvature, triangular thread screw type in accordance with ISO regulations and square thread screw filleted with small radius partially. It was found that square thread screw filleted with small radius was more effective on stress distribution than other dental implants used in analyses. Additional analyses were performed on the implant with square thread screw filleted with small radius for verying design parameters, such as the width of thread end, the height of the thread of the implant and load direction, to determine the optimum dimensions of the implant. The highest stress concentration occurred at the region in jaw bone adjacent to the first thread of the implant. The maximum effective stress induced by a 15 degree oblique load of 100 N was twice as high as the maximum effective stress caused by an equal amount of vertical load. Stress distribution was more effective in the case when the width of thread end and the height of thread were p/2 and 0.46p, respectively, where p is the pitch of thread. At last, using tensile force calculated from the possible insert torque without breading bone thread, finite element analysis was performed on the implant to calculate pre-stress when the primary fixation of the implant was operated in jaw bone. The maximum effective stress was 136.8 MPa which proven to be safe.

STATEMENT OF PROBLEM: One of common problems associated with single teeth dental implant prosthetic is the loosening of screws that retain the implants. PURPOSE: The maintenance of screw joint stability is considered a function of the preload achieved in the screw when the suggested initial tightening torque is applied. The purpose of this study was to investigate acquired preload after initial clamping torque for estimating screw joint stability. MATERIAL AND METHODS: A comparative study on the effect of initial clamping of two types of implant systems with different connections was conducted. Three dimensional non-linear finite element analysis is adopted to compare the characteristics of screw preloads and stress distributions between two different types of implant systems composed with abutment, screw, and fixture under the same loading and boundary conditions. RESULTS: 1. When the initial clamping torque of 32Ncm was applied to the implant systems, all types of implants generated the maximum effective stress at the first helix region of screw. 2. Morse taper connection types of implants generate lower stress distributions compared to those by butt joint connection types of implants due to large contact surface between abutment and fixture. 3. The internal types of implant systems with friction grip type implant systems have higher resistance to screw loosening than that of the external types of implant systems since the internal types of implant systems generated larger preload than that generated by the external types for the same tightening moments.

STATEMENT OF PROBLEM: The researches on the influence of design variables on the stress distribution in cortical and trabecular bones and on optimal design for implant system were limited. PURPOSE: The purpose of this study is to identify the sensitivities of design parameters and to suggest the optimal parameters for designing the onebody type implant system. MATERIAL AND METHODS: Stresses arising in the implant system were obtained by finite element analysis using a three dimensional model. An onebody type implant system [Oneplant (Warrantec. Co. Ltd., Korea)]was considered in this study. Vertical load(150 N) was applied on the top of the abutment along the axial direction. The initial design variables set for sensitivity analysis were radius of fixture, numbers of micro thread, numbers of power thread, height of micro thread, fixture length, tapered angle of fixture, inclined angle of thread, width of micro thread and width of power thread. The statistical technique of Design of Experiments(DOE) was applied to the simulation model to deduce effective design parameters on stress distributions in bones. The deduced design parameters were incorporated into a fully automated design tool which is coupled with the finite element analysis and numerical optimization to determine the optimal design parameters. RESULTS: 1. The result of sensitivity analysis showed six design variables - radius of fixture, tapered angle of fixture, inclined angle of thread, numbers of power thread, numbers of micro thread and height of micro thread - were more influential than the others. 2. The optimal values of design variables can be deduced by coupling finite element analysis (FEA) and design optimization tool(DOT).
