PURPOSE: To cmpare the clinical results of complex tibial plateau fractures treated by hybrid external fixation and dual plate fixation. MATERIALS AND METHODS: We studied forty patients with Schatzker type V and VI fractures respectively and selected twenty seven patients who were followed at least one year between January 2000 and December 2005. We evaluated the clinical results in which fourteen fractures with hybrid external fixation were compared with thirteen fractures with dual plate fixation. The clinical results were evaluated according to Knee Society Clinical Rating System and the statistical analysis was performed by Student t-test. RESULTS: There were no significant differences in terms of bone union time (average union time: dual plate fixation 13.8 weeks, hybrid external fixation 14.2 weeks). The quality of osseous reduction was superior in the fractures with dual plate fixation than those with hybrid external fixation. There were significant differences in functional score (average functional score: dual plate fixation 73, hybrid external fixation 62), but not in average knee score. CONCLUSION: The hybrid external fixation can be a useful modality for treatment of complex proximal tibial plateau fractures. But the good quality of the fracture reduction by dual plate fixation may be a indicator for favorable prognosis for satisfactory knee function.

Kerion celsi caused by Trichophyton(T.) rubrum is rare endemically and there has been no report of it in Korean literatures. We report a case of karion celsi caused by T. rubrum in a 71-year-old male, who showed anindurated, swollen, boggy mass exuding pus on the right parietal scalp for about 7 weeks. The colonies and microconidia were identified as T. rubrum by fungus culture in potato dextrose agar. After administration of itraconazole for 11 weeks, the lesion was healed and the regrowing of new hairs was observed.

BACKGROUND: Hearing loss is associated with environmental noises. Not only the strength of the noise but also the exposure time of that seems important. We investigated to find the factors associated with hearing loss in pilots. METHOD: For the anlysis of hearing loss in pilots in the air force, we performed an audiometiric test on 563 pilots from 2000 to 2001 and analysed the results. REUSLT: The type of aircraft or regiment is not associated with hearing loss. The age, tenure and total flight time are the factors associated with hearing loss, especially in the high frequency zone. The flight time in the recent six months is shown not to be associated with hearing loss which means an exposure to noise in a longer term is important. In this study, the hearing threshold increased at 6,000 Hz regardless of age. CONCLUSION: The reason may be due to the noise environment of pilots. Therefore an additional study about pilots' normal limits of hearing threshold at 6,000 Hz and clinical meanings of that is necessary.

7.A Study on Vestibular Function of Workers with Noise Induced Hearing Loss in Air Base.
Korean Journal of Aerospace and Environmental Medicine 2002;12(2):60-64
PURPOSE: This study was conducted to investigate the influence of chronic noise stimulation on vestibular function system. METHODS: We selected 19 workers as study group, The study group workers had NIHL (Noise Induced Hearing Loss, Hearing threshold >or=30 dB at 4,000 Hz in both ears), had exposed noise at least 5 years. Also, we selected 11 workers as reference group who had not exposed workplace noise. We conduct-ed SHA (Slow Harmonic Acceleration) test at 0.01, 0.02, 0.04, 0.08, 0.16 Hz and got gain, phase in both groups. RESULTS: The gains were within normal limits in both study and reference groups and not significantly between two groups. The phase were within normal limits except for 0.16 Hz in study group and showed sig-nificant difference only at 0.01 Hz between two groups. The mean gain and mean hearing threshold at 4,000 Hz and 8,000 Hz had negative correlation (r=-0.271) but it was not significant. CONCLUSION: This study do not reveal the significant vestibular function impairment of workers with NIHL. But further study is required to inves-tigate the vestibular compensation.

The blue rubber bleb nevus syndrome(CRBNS) is a rare disorder characterized by distinctive vascular malformations of the skin and gastrointestinal tract. The syndrome is associated commonly with iron deficiency anemia due to gastrointestinal bleeding. Most cases are sporadic, although a few have been reported with autosomal dominant inheritance. We report a case with clinical characteristics of the blue rubber bleb nevus syndrome. The patient had typical skin manifestations of the BRBNS and chronic iron deficiency anemia. However, we could not find any gastrointestinal vascular malformations radiologically.

BACKGROUND: Wound fluid is believed to contain growth factors produced by cells involved in the healing process. One of the beneficial effect of occlusive dreesing is the retention of released fluid from the wound, which is thought to accelerate wound healing. However, there was no report how suction-induced or cryo-induced bulla flicmight affect the healing of the wound itself. OBJECTIVE: Therefore, we have examined the effect of sucior-or cryo-induced bulla fluids on the in vitro growth of human dermal fibroblasts. METHODS: Suction-or cryo-induced bulla fluid were sterilely collected from the suction blisters and cryotherapy induced bulla, respectively. After seeding in optimal growth media on day 0, cultures of normal fibroblasts were supplemented with various concentrations of human serum, suction-induced bulla fluid, and cryo-induced bulla fiuid on day 2, 4, 6, 7, or 8. RESULTS: As determined by cell counts or 3H-thymidine incorporation, the effect of human serum were much more than those of suction-induced. Bulla fluid on the growht of fibroblasts. Although slight mitogenic effects were observed in the case of 5% cuyo-induced bulla fluid, 10% cryo-induced bulla fluid inhibited the growth of the fibroblasts as wello CONCLUSION: These results suggested that suction-induced bulla fluid was not a whole human serum but a diluted serous material having limited stimited stimulated effect to the growth of the fibroblasts, and cryo-induced bulla held the unknown inhibitory or toxic factors as well.
