The incidence of tibial fracture is increasing due to increasing tendency of traffic and industrial accidents. In general, the tibial fracture is treated with closed method but it is difficult because of its anatomical cbaracteristics. We have been treated tibial fractures with total contact short leg cast which supports the 7 points such as tibial condyle, tuberosity, margo anterior, medial malleolus, fibular head, lateral malleolus and heel rigidly and molding it as trangiular shape like the tibia using both palms and fingers The advantages of this cast sre to prevent rotation, to promote osteogenesis with early weight bearing and to prevent ankylosis of knee joint. In fact, the sverage healing time was 14weeks Rotation, nonunion, angulation ove cast sore, nerve injury were not noticed and the shortening was 4. 1mm in closed fractures, 5. 3mm in open fractures.

We recently experienced an unexpected episode of bilateral vocal cord paralysis following endotracheal extubation after uvulopalatopharyngoplasty and tonsillectomy in 64-year-old man. The patient had no any other clinical manifestations regarding larynx or vocal cord except sleep apnea syndrome prior to this operation. The surgical procedure lasted almost 120 minutes and surgery and anesthesia was uneventful. After restoration of his spontaneous respiration, we tried extubation as usual method. Regardless his effort of spontaneous respiration for several times, he was suddenly apneic and showed declining of arterial oxygen saturation on the pulse oximeter (SpO2). Then we tried reintubation as a decision of laryngeal spasm. This alternative episode of extubation and reintubation was tried again and the causative factor of this respiratory impairment was confirmed as bilateral vocal cord paralysis by fiberoptic bronchoscopic examination in the operating room. Almost two thirds of vocal cord function was restored after six months of operation.

A poor prognosis of oral squamous cell carcinoma (SCC) is partly due to the invasiveness and metastasis of the tumor. A key element in tumor invasion and metastasis in the degradation of extracellular matrix is matrix metalloproteinases (MMPs). This study was performed to determine the expression of MMP-2 and MMP-9 of oral SCCs with regard to the histologic invasiveness and differentiation in 5 normal oral mucosa and 36 oral SCCs. The histologic invasiveness of oral SCCs were classified into 4 grades. The differentiation of oral SCCs was divided into 3 grades. The streptavidin-biotin immunohistochemical staining, using MMP-2 and MMP-9 monoclonal antibodies, was performed to determine the expression of MMP-2 and MMP-9. The expression of MMP-2 was positive in 6 of 17 oral SCCs with weak invasiveness and was positive in 7 of 19 oral SCCs with strong invasiveness. The MMP-2 expression did not increase significantly with respect to the invasiveness of oral SCCs (P>0.05). The expression of MMP-9 was strongly positive in 6 out of 17 SCCs with weak invasiveness and was strongly positive in 14 of 19 SCCs with strong invasiveness. The MMP-9 expression increased significantly with respect to the invasiveness of oral SCCs; the stronger the expression, the stronger the invasiveness (P<0.05). The expression of MMP-9 was in 57.9% of well differentiated SCCs, 57.1% of moderately differentiated ones, and 33.3% of poorly differentiated SCCs. The expression of MMP-2 and MMP-9 did not increase significantly with respect to the histologic differentiation. We conclude that with respect to the invasiveness, the MMP-9 expression increases significantly in oral SCCs but the MMP-2 expression does not; and that with respect to the histologic differentiation, their expressions do not increase significantly. These results suggeste that MMP-9 can be used as a tool to evaluate the invasiveness of oral SCCs.
