Fifty four consecutive total knee arthroplasties were reviewed to compare the accuracy of extramedullary versus intramedullary tibial resection guides. An extramedullary guide ( Group I ) was used in 25 cases and an intramedullary guide ( Group 2 ) was used in 29 cases. Group 1 system included the LCS knee system and Group 2 system included the Whiteside Ortholoc Advantim total condylar knee system. Preoperatively, the two groups were similar, with no statistical significant differences observed in diagnosis, alignment, and patient age. Postoperative tibial component alignment angles were similar in both group (Group 1, 0.8degrees varus; Group 2, 1.1degrees varus ). In group 1, 84% of tibial components were aligned within 2degrees of the 90degrees goal and in group 2, 83% of tibial components were aligned within the same range ( p > 0.05 ). In all cases, an intramedullary guide was used to prepare the distal femur. In femorotibial angles, with group 1 averaging 4.2degrees valgus versus 4.7degrees valgus in group 2 (p > 0.05). If the optimal femorotibial angle was defined by the range from 5+/-2, it was achieved in 76% in Group 1 and 72% in Group 2 ( p > 0.05 ). This study demonstrates no significant differences between the extramedullary and intramedullary group not only in optimal tibial component alignment angle but also in optimal femorotibial angle. This means that each system is satisfactory for the tibial side, but it is more important for the surgeon to appreciate that the indications, potential limitations and sources of errors are unique to each system and to decide which system to use according to the particular case in question.

Those unstable comminuted colles' fractures in which the dorsal or volar cortex of radius is fragmented, destroying the buttress of the bone essential to maitnain the alignment, result various residual complications. To overcome those complications, additional methods of fixation, including pin and plaster, percutaneous pinning or some forms of external fixations have been employed. Clinical analysis were made in 22 cases of unstable comminuted Colles fractures which were treated during January 1975 and September 1980 and followed-up for 6 months to 4 years and 7 months. The results were as follow: 1) The fracture occure predominantly in male (4 to 1). 2) Among the 9 cases treated with manipulative reduction followed by cast immobilization, 6 showed satisfactory results while the other 3 did not. 3 Among the 13 cases which were treated by coatinuous traction incorporated in cast, 10 showed satisfactory results and 3 did not. 4) Complications observed were; 9 cases of limited supination of affected forearm. 2 cases of ankylosed wrists. 2 cases of pin-tract infections, and 1 case of transient superficial radial nerve palsy.

It is indispensable to cover the skin defect when bone or tendon is exposed. In case of inevitable amputation of an extremity, it is possible to harvest a free flap from the amputed limb for providing coverage of the other wound. This technique allows immediate wound coverage without the morbidity of an additional donor site. We experienced an electrical burn case with inevitahle wrist disarticulation and successfully treated soft tissue defect of ankle using free vascularized flap.

A 56-year-old woman presenting a 10-year history of atrophic discoid patches with underlying subcutaneous nodules was seen. These skin lesions were distributed on the upper arms bilaterally. Biopsy specimens taken from the lesional skin showed epidermal and dermal changes consistent with the discoid lesions of the cutaneous lupus erythematosus. Deep dermis and subcutaneous fat tissue revealed sclerosis and fibrinoid alterations of the collagen and necrosis of fat cells, the features corresponding to the lupus ei ythematosus profundus. She had no laboratory evidences suspective of systemic lupus erythematosus or other connective tissue diseases. This patient with lupus erythernatosus profundus which cleveloped subsequent to the discoid lesion is consiclered to be a rarely encounteririg observation in lupus erythematosus.

riie snbjects werc 269 patients with uncomplicated gonococcal urethritis, who visited the Veiereal Disease Clinic of Choong-Ku Public Health Center in Fieoul from August to Decernber 1984. ()ni hundred and four of 108 patients treated with 1.anamycin, 2 gm, IM plus anipi illin,3.5 gm, p0 plus probenecid, 1 gm, PO regirrien recovered with 65(62. 5 post-gonococcal urethritis(PGlJ) and 4(3.7%) failed, One hundred and seven of III patients treated with kanamycin, 2 gm, IM plus talarnpicillin, 2 gm, PO plus probenecid, 1 gm, po regimen recovered with 71 (66. 4% ) post-goriococcal urethritis and 4(3. 6%) failed. It is suggeste,d that both these antibiotic comlbination regimens have similarly good effect in the treatment. of gonococcal urethritis.

Anti-T cell monoclonal antibodies(OKT series. OKT4a, OKTSA, OKT)1) immunoperoxidase technique study for the presence of T cells in cutaneous lesions from four patients with erythema multiforme showed that most dermal and epidermal lymphoid cells were reactive with monoclonal antibodies to anti-pan T cell (l3KT11) in this semiquantitative assay. In the dermis most of the perivascular lirmphoid infiltrates were reactive with anti-helper/inducer T cell antibody, but in the epidermis and in the derrnopidermal interface the predominant cells were identified as suppressor/cytotoxic T cells. The histologic and immunopathologic changes in erythema multiforme appear to be due in part to cellular immune rnechanisms with the lyrnphocyte as the predominant effector cell. But complex interplays with other humoral immune mechanisms might be in work for the development of erythema multiforme.

In Systemic lupus erythematosus several correlations with anti-Ro antibodies have been noted. They are the increased incidence of photos nsitive skin disease, rheumatoid factor positivity, Sjogren's syndrorme, and a greatly increased incidence of the DR 3 hapIotype. In this study we examined the prevalence of anti-Ro anibodies(not concerned for anti-La, Sm, RNP) by double immunodiffusion method among thirty two Korean patients with systemic lupus erythematosus who had positive results on routine fluorescent antinuclear antibody test. We also have seen skin manifestations on these patients, and examined if there is any difference of the incidence for each skin sign between anti-Ro positive and negative subgroups. From the data obtained, the proportion of anti-Ro positives among these patients with systemic lupus erythematosus was 53% Regarding to the difference of the incidence of cutaneous rnanifestations between the two subgroups, the photosensitivity reaction was recongnized as a uniqu symptorn rnore prevalent (p<0. 05) in anti-Ro positive subgroup with the frequency of 65%.

Lichen planus is rare in Korea. and oral lichen planus is even rarer. To our knowledge, this is the first case reporting in Korean dermatological literature. 57 year-old man was seen for erythema with white striation on the oral mucosa in December 1981. The initial lisior s appeared on the buccal mucosa of left side of oral cavity 10 months ago. Thereafter he noticed similar lesions on the right side of buccal mucosa, hard palate, left side of upper and lower gingiva and left side of the lower lip. Histopathological and direct immunofluorescence studies showed typical features of lichen planus. Administration of griseofulvin(0.5gm. of Fulvicin' daily) for 4 weeks resulted in no clinical improvement. Oral retinoid(25mg of Ro 10-9359 daily) for 11 weeks resulte3 in healing of lesions with no side effect except slight dryness of the mouth.
