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.

The use of artificial skins for full thickness wounds is an accepted technique, but unfortunately the take rate is low and the aesthetical result is not acceptable. The freeze-drying treatment of allogenic tissues can destroy cells with preserving the structural organization of extracellular matrices, permitting allogenic transplantation. In this study we investigated a new method to process the allogenic skin for transplantable allogenic dermis and this dermis was evaluated in a full thickness wound model. The results are as followings; 1. After treatment with NaCl and SDS solution and then with freeze-drying method, the allogenic dermis shows acellular dermal matrix with preserved normal extracellular matrix. 2. This allogenic dermis became completely incorporated into the wound without evidence of rejection or replacement by scar tissue. 3. The take rate of thin autografts overlying the allogenic dermis that were applied simultaneously was comparable to take rate of autograft alone. 4. The reduction in secondary contraction by allogenic dermis treated wounds was significant. 5. After grafting with cultured keratinocytes, the degree of epithelial coverage was 70% at 2 weeks. In conclusion, the allogenic dermis processed with our method displayed lack of antigenicity, and rapid revascularization. This allogenic dermis can permit simultaneous engraftment of an overlying STSG or cultured kerationocytes, reduce secondary contraction and improve cosmesis of full thickness wounds.

PURPOSE: The purpose of this study was to analyse the characteristics of acalculous cholecystitis (AC) compared with those of calculous cholecystitis (CC), and also to find the relationship of preoperative radiologic findings to the classification of pathological degree of inflammation of the gallbladder in AC. METHODS: Between March 1996 and June 2000 a total of 163 patients undergoing cholecystectomy for cholecystitis were divided into group AC (21 patients) and group CC (142 patients) and retrospectively studied by analyzing clinical data. RESULTS: The incidence of AC among cholecystitis cases was 12.9%. there was male preponderance in group AC whereas female preponderance in group CC (P<0.036). The pulse rate (P<0.02) and white blood cell count (P<0.003) were significantly elevated in group AC. Possible etiological factors were found in 6 cases (28%) in group AC. The rates of preoperatively observed pericholecystic fluid collection in US (P<0.033) and dilatation of the gallbladder in CT (0.012) were significantly higher in group AC than in group CC. Additionally, the rate of tube drainage during surgery was significantly higher in group AC than group CC (P<0.02). Finally, wall thickness (P<0.05), dilatation (P<0.05) of the gallbladder in CT and the total sum of findings in CT (P<0.01) and US (P<0.05) were strongly related to the degree of inflammation of the gallbladder. CONCLUSION: The majority of AC patients exhibit nonspecific clinical findings, often delaying diagnosis; however, if it develops, AC tends to display more acute and inflammatory characteristics than calculous cholecystitis. laparoscopic surgery cannot be sucessful in cases of delayed diagnosis. US, CT and scintigram are useful diagnostic tools if we interpretate each finding in relation to the severity of inflammation.
