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: There are many studies focused on the effect of shape of fixtures on stress distribution in the mandibular bone. However, there are no studies focused on the effect of the abutment types on stress distribution in mandibular bone. PURPOSE: The purpose of this study is to investigate the effect of three different abutment types on the stress distributions in the mandibular bone due to various loads by performing finite element analysis. Material and method : Three different implant systems produced by Warantec (Seoul, Korea) were modeled to study the effect of abutment types on the stress distribution in the mandibular bone. The three implant systems are classified into oneplant (Oneplant, OP-TH-S11.5), internal implant (Inplant, IO-S11.5) and external implant (Hexplant, EH-S11.5). All abutments were made of titanium grade ELI, and all fixtures were made of titanium grade IV. The mandibular bone used in this study is constituted of compact and spongeous bone assumed to be homogeneous, isotropic and linearly elastic. A comparative study of stress distributions in the mandibular bone with three different types of abutment was conducted. RESULTS: It was found that the types of abutments have significant influence on the stress distribution in the mandibular bone. It was due to difference in the load transfer mechanism and the size of contact area between abutment and fixture. Also the maximum effective stress in the mandibular bone was increased with the increase of inclination angle of load. CONCLUSION: It was concluded that the maximum effective stress in the bone by the internal implant was the lowest among the maximum effective stresses by other two types.

A silicone-covered modified Gianturco stent in patients with malignant esophageal stricture is an easy, safe, and effective palliative procedure, but reports of complications arising from stent placement in patients with this condition are numerous. There have been no reports of fracture of the modified Gianturco esophageal stent. We report a case of stent fracture in association with gastric migration of modified Gianturco esophageal stent in a patient with malignant esophageal stricture. It appears that the fracture was probably due to oxidation of the stent by gastric juice.
