Reactive perforating collagenosis, first described by Mehregan et al in ]967, is a skin disorder characterized by transepidermal eliniination of altered collagen fibers. This rare disease appears as recurrent, umbilicated, crusted papules in response to minor trauma. We report here a case of reactive perforating collagenosis in a 21-year-old man. Examination of the skin revealed a number of centrally umbilicated, asymptomatic papules filled with keratotic plugs in various development and regression. The lesions were distributed on the dorsa of the hands, face, and neck. The biopsy spccimen showed a few of thin bundles of collagen which v ere extruded from the dermis through the atrophic epidermis and the turinels within the epidermis, reaching the buttom of the plug.

A 14-year-old boy and his 16-year-old elder brother, who had generalized tinea corporis for 1 and 3 years respectively, developed multiple discrete, non tender soft tumors on the scalp, forehead, neck and extremities. The boys were well nourished and had no systemic diseases. Histopathologic examination of the subcutaneous nodules revealed a well encapsulated granuloma containing lobulated granules characteristic of mycetoma; these granules consisted of septated fungal hyphae with vesicles. The dermatophyte isolated from the tumors was identified as Trichophyton schoenleinii.

Authors presented the gratifying result of treatment of chronic osteomyelitis with overlying skin defect and/or poor skin condition, which developed the wide skin necrosis after saucerization and resulted the second skin graft necessary. Five cases were treated by primary extensive saucerization of tibia which left a cavity with bleeding walls. The exposed bony surface with bleeding walls was covered by delayed free skin graft when the good granulation covered the bony surface. Through this experience, delayed free skin graft is justified the best procedure in these cases to cover the post-surgical raw bone surface and to have primary healing of the bone infection. A method of hemicylindrical pedunculated skin graft to obliterate the deeply excavated surgical bony defect is introduced.

Injury of the hand has been progressively increasing with industrial development in recent years. In spite of careful and proper surgical treatment, orthopedic surgeon is frequently faced with a hand which fails to function properly because of limited flexion or extension in the metacarpophalangeal and interphalangeal joints. The author has experienced 13 cases of stiff fingers from 1968 to 1973 and the result of the treatment is reported in this paper. 1. 12 cases out of 13 were in age group between 11 to 30 years of age. 2. The types of injury were variable as; 5 cases of laceration, 5 cases of crushing injury, 2 cases of wringer injury, and 1 case of open fracture. Those were injuried by roller, glass, pressor, drill and gun-shot. 3. Involved anatomical structurs in stiff finger joints were much variable, mainly depending upon varying degrees of intial injury. We have classified them roughly in 4 groups; 1 Ruptured or sutured tendon adhesion. 2. Intrinsic muscles and tendon adhesion, and capsule and collateral contracture. 3. Resultant massive scar contracture including joints, and ligaments. 4. Osseus adhesion with soft tissues including tendon. 4. 17 times of reconstructive surgery were performed in 14 stiff joint with skin graft, Z-plasty, adhesiolysis, capsulotomy, capsulectomy, resection of cord portion of collateral ligament, tenolysis and arthroplasty alternatively or unitedly except of tenodesis and arthrodesis in remained 2 joints. 5. Post-operative immobilization was performed with plaster splint, stein mann pin and K-wire accordingly. The period of immobilization was variable from 2 weeks to 4 weeks. Physical therapy is enforced to begin as soon as possible. The period of follow-up was from 2 months to 19 months and average 6 1/2 month.. 6. Consequently, the range of active motion is increased to 55° and passive motion to 61° from preoperative status in PIP and MP joints. 7. The preoperative position of the joints and cause of the joint stiffness don't gave no significant influence to the end result. Satisfactory end result was obtained by proper, careful and meticulous surgery with early and extensive physical therapy.

The use of antituberculous drug made it possible to develop the radical operative procedure in the treatment of the spine tuberculosis. The anterior fusion is the most frequently used surgical measure in the treatment of the spine tuberculosis but several problems were observed not infrequently. One hundred and twenty-nine cases of childhood spine tuberculosis were treated by the anterior spinal fusion for the period of ten years from 1968 to 1977 at Seoul National University Hospital, and following results were obtained. Problems of the anterior spinal fusion could be divided into two categories; one is the complications and the others are difficulties in the surgical procedure. Complications of the anterior spinal fusion were divided into early and late. Early complications include graft failure, pulmonary problems, cord compression and spinal fluid leakage. Late complications include increasing kyphosis, draining sinus and graft failure. Degrees of increasing kyphosis were the greatest in the age group between the and five years, and greater degrees of increasing kyphosis were observed in more joint involvement. Increasing kyphosis were observed more frequently in longer follow up. The causes of increasing kyphosis could be considered as the relative discrepancies between the growth of the anterior and posterior comparment, and graft failure.
