A precise fit of the implant prosthesis is one of the most important factors in preventing mechanical complications. To analyze the degree of the misfit of implant prosthesis, a modal testing experiment was accomplished. And to interpret the modal testing analysis mathematically, three-dimensional finite element models were established. In the experimental modal testing analysis, with a laser displacement meter, FFT analyzer, impact hammer, etc., natural frequencies of the models with various degree of prosthesis fit were determined after the frequency response function were calculated. In the finite element analysis, the natural frequencies and mode shapes of the models which simulated those of experimental modal testing were computed. The results were as follows : 1. Natural frequencies of the prosthesis-abutment were related to the contact state between components. 2. In the modal testing experiment, the natural frequencies increased from 50micrometer to 200micrometer gap and reached a plateau. 3. In the finite element analysis, the natural frequencies decreased gradually according to the increase of the gap size. 4. In the finite element analysis, the mode shapes of model 1 with misfitting prosthesis showed different patterns from those without misfitting prosthesis. 5. The devices including a laser displacement meter used in this study were useful for measuring the natural frequencies of an implant prosthesis which had various degrees of fit.

We report a case of a phototoxic reaction in a 48-year-old female induced by griseofulvin ingestion. The patient hac! erythematous papules, vesicles and patches on the sun-exposed areas. Phototest revealed a decreased minimal erythemal dose to UVA (10J/cm). Photopatch tests with 1%, 5%, 10% Griseofulvin ointment and vaseline as a control and photoingestion tests with Griseofulvin (50mg b.i.d.) were all negative. After the cessation of Griseofulvin, her skin lesions were markedly improved with complete loss of photosensitivity.

Erythromelalgia is a rare disorder characterized by intense hun ing pain in the distal extremities associated with erythema and increased skin temperature. The patient was a 42- year-old woman with a 5 year history of burning pain, erythema, and warmth of the skin on both hands and feet. She had been suffering from bronchiali astalima since childhood. The onset of the symptoms were temporally related to the attacks of hei bronchial asthma. Physical examination revealed mottled dusky red patches on her both ha ids and feet, and purplish acrocyanosis on the finger and toe tips. We present a case of secondary erythromelalgia associated with bronchial asthma and acrocyanosis.

We report two cases of Darier's disease improved with Etretmate in the 44-year-old father and his 18-year-old son. Clinically, multiple dirty brownish, verrucous, discrete or confluent papules and plaques were noted on their back, abdomen, and face. Histopathologically, both of them demonstrated hyperkeratosis, suprabasal acantholysis, acantholytic cells in the lacunae, corpsronds, grains, and dyskeratotic cells. Oral Etretinate 30mg daily was given in both cases with remakable improvement 3 weeks after treatment. Six months later, they showed almost total clearin, of their skin lesions. No specific adverse effect was noted. There has been no evidence of recurrence for 6 months follow up period.

A 29-year-old woman had multiple, umbilicated papules on her fingers for 2 months. Skin biopsy specimen showed transepidermal perforation filled with plug of cellular debris, degenerated collagen and mucinous material. In the dermis, there were necrobiosis and peripheral palisading of mononuclear cells. Special stainings including masson's trichrome, alcian blue, acid orcein, and PAS showed necrobiotic collagen fibers and acid mucopolysaccharides on the necrobiotic zone and trasepidermal elimination canal. Topical application of 0.05% Clobetasol-17-propionate ointment improved her lesion.

We report two cases of recurrent BCC in a 51- year-old woman and a 39-year-old woman which had been misdiagnosed aind treated as pigrnented nevi. Complete surgical resections were done followed by reconstruction using local rhombic transposition flaps. Final cosmetic results were excellent and no local recurrence was noticed during one year follow-up.

Calcifying aponeurotic fibroma is a rare benign tumor found primarily on the hands or wrists of children and adolescents. It has a tendency of local invasion, and a high recurrence rate after excision. An 11-year-old boy had a hard indurated. 3 x 3cm-sized, nodule on the right sole for 3 years. A biopsy specimen showed heavy focal calcification within areas of densely paked stromal fibroblastic cells. Some fields contained multinucleatec giant cells and chondroid metaplasia. There were infiltrative growth patterns of fibroblastic cells extending into the adjacent adipose tisse and blood vessels. There was no evidence of reccurence at 3 months after the operation.

We have attempted to define the acetabular remodelling after varus derotation osteotomy and limitations of pelvic osteotomy in the treatment of DDH. We studied the case of thirty eight patients (42 hips) who were divided into three groups according to age at operation and into two groups, subluxation with acetabular dyaplasia and complete dislocation. The cases were evaluated the influence of femoral remodeling, age, acetabular response and instability and requirement of other additional surgery. The length of follow up ranged from two to fourteen years. A return to a valgus femoral neck shaft angle by remodeling was observed in case without avascular necrosis of femoral head. Acetabular correction by remodeling occurred in case of well reduced the femoral head in the socket. Acetabular remodeling was observed even in age of 8. Twenty eight of 42 hips which were complete dislocation required no pelvic osteotomy. A varus derotation osteotomy is a necessary procedure for hip stability and open reduction in treatment of DDH. Good results should be anticipated in patient whose femoral head was well seated in the acetablum.

To determine the incidence rate of accidents and its associated factors, a prospective survey was carried out in a rural area of a total of 1,360 residents for 1 year from January 1 to December 31, 1988 in Shin-am Ri, Jungdong Myun, Sangju Kun, Kyeongpook Province. Data for accidents were collected by the community health practitioner who is working at Primary Health Post in Shin-am Ri. A total number of accident cases was 85 among 1,360 persons during one year study period, and annual incidence rate was 62.5 per 1,000 persons. The highest incidence rate of accident was observed in the age group of 30-39 was 179.8. The incidence rate of accident in male was 86.5 which was about 2 times that in female. In male, the highest incidence rate was seen in 30-39 age group and in female, 60-69 age group. The highest incidence rate of accident was observed in spring (29.4%) and summer (29.4%), and the lowest in fall (17.7%). The highest incidence rate of accident was observed in Friday (24.5%) by day of week, and between 9 a.m. to 12 a.m. by time zone. The most frequent use of medical facilities was Primary Health Post (51.8%) and the next was clinic (38.8%). Mean duration of treatment was 9.8 days. The accident occurred in the room and kitchen (23.5%), in the yard and barn (23.5%), on the road (22.4%), and in the rice field and dry field (20.0%). The causes of accident were motor vehicle accident (20.0%), piercing or cutting (20.0%), collision or fighting (12.9%), and poisoning (11.8%) in order of frequency. The most common type of injury was open wound which was 43.5%. The most common tool of accident was farm machine which was 23.5%. The most common injured part of body was extremity 55.3%.
