The number of skin graft operations following the soft tissue injuries has been increasing year after .year, as the number of industrial business is growing fast in Seoul district. We have performed one hundred and two cases of skin graft, mainly for the extremities injury in the orthopedic surgical department alone during last sixteen months (from January. l968 to Apri1, 1969) including two plastic operation for the penile skin which involves, very rarely because of an anatomical .stand point The plastic repair of penile skin was done by means of Goodwin's technic. The pedicle skin wag donated from the scrotum for the completely necrotized penile skin which was developed following the attempt of removal of the penile paraffinoma.

To evaulate the effectiveness and risk factors for shunt failure of the Blalock-Taussig shunt in neonates, we analyzed the 21 neonates who were undergone Blalok-Taussig shunt operation at Dong-A University Hospital from December 1991 to Feburary 1996. We evaluated operative mortality, patency of the shunt. and distortion of pulmonary artery. We also determined the risk factors for the shunt failure. Age at operation was from 1 day to 30 days(mean 11.7 days). Weights were 2.4 to 4.5kg(mean 3.1 kg). The underlying lesions included severe tetralogy of Fallot with pulmonary stenosls or atresia(N=11) and single ventricle varieties with. pulmonary stenosis or atresia(N=10). Prostaglandin E1 was given in 13 neonates prior to operation. The mean preoperative(prior to prostaglandin El therapy) and postoperative arterial oxygen tension were 30.1 mmHg and 46.3 mmHg respectively(P<0.01). The shunt was performed through a left thoracotomy in 11 patients and through a right thoracotomy In 10. A 5 mm graft was used in 15 patients and a 4 mm graft in 6 patients. The incidence of early shunt occlusion was 9.5%(2 patients). The hospital mortality was 9.5%(2 patients with early shunt occlusion). Univariate analysis revealed that body weight of 2.6 kg or less(p=0.021), pulmonary artery size of 3mm or less(p=0.008), and 4 mm graft (p=0.021) were risk factors predictive of early shunt failure. The patency rate of the shunt in hospital survivors was 100% at mean ollow-up of ll.3 months(There was not death or reoperation related to shunt failure). 10 patients were catheterized during postoperative follow-up. There was no significant distorsion of pulmonary artery. So we concluded that the modified Blalock-Taussig shunt in neonates was excellent in the hospital survivors.

Myxofibrosarcomas (MFSs), which consist of multiple nodules with a variable cellular population in a myxoid matrix, are primarily located in subcutaneous tissue. Pleomorphic hyalinizing angiectatic tumors (PHATs) are rare soft-tissue tumors characterized by a proliferation of highly pleomorphic spindle or polygonal cells and abundant ectatic blood vessels in cellular or myxoid stroma. We present here an unusual case of a high-grade MFS with a PHAT-like appearance. A 67-year-old man presented with an asymptomatic subcutaneous mass in the right forearm. The tumor had myxoid, hypo-, and hypercellular areas with highly pleomorphic spindle or polygonal tumor cells that showed frequent mitoses and nuclear pseudoinclusions. Foci of punctuate necrosis and inflammatory infiltration were present throughout the tumor, and abundant ectatic, thick-walled vessels containing blood clots were noted. The tumor cells were immunohistochemically positive for vimentin but negative for CD34, S-100 protein, smooth muscle actin, desmin, and bcl-2.

BACKGROUND: the prediction on changes in the lung function after lung surgery would be an important indicator in terms of the operability and postoperative complications. In order to predict the postoperative FEV1 - the commonly used method for measuring changes in lung function- a comparison between the quantitative CT and the perfusion lung scan was made and proved its usefulness. MATERIAL AND METHOD: The subjects included 22 patients who received perfusion lung scan and quantitative CT preoperatively and with whom the follow-up of PFT were possibles out of the pool of patients who underwent right lobectomy or right pneumonectomy between June of 1997 and December of 1999. The FEV1 and FVC were calibrated by performing the PFT on each patient and then the predicted FEV1 and FVC were calculated after performing perfusion lung scan and quantitative CT postoperatively. The FEV1 and FVC were calibrated by performing the PFT after 1 week and after 3 momths following the surgery. RESULTS: There was a significant mutual scan and the actual postoperative FEV1 and FVC at 1 week and 3 months. The predicted FEV1 and FVC(pneumonectomy group : r=0.962 and r=0.938 lobectomy group ; r=0.921 and r=913) using quantitative CT at 1 week postoperatively showed a higher mutual relationship than that predicted by perfusion lung scan(pneumonectomy group : r=0.927 and r=0.890 lobectomy group : r=0.910 and r=0.905) The result was likewise at 3 months postoperatively(CT -pneumonectomy group : r=0.799 and r=0.882 lobectomy group : r=0.934 and r=0.932) CONCLUSION: In comparison to perfusion lung scan quantitative CT is more accurate in predicting lung function postoperatively and is cost-effective as well. Therefore it can be concluded that the quantitative CT is an effective method of replacing the perfusion lung scan in predicting lung function post-operatively. However it is noted that further comparative analysis using more data and follow-up studies of the patients is required.

The present study evaluates the type, frequency and location of basal cell epithelioma, as well as the age and sex distribution of patients and the recurrence rate of basal cell epithelioma. In this study 116 patients, who visited Severance hospital during the last 15 years from Jan. 1, 1967 to Dec. 31, 1981 and were diagnosed histopathologically as having basal cell epithelioma, were analysed.
