Epidermoid cysts occur rarely on the palms and soles, where hair is not present. These cysts have long been assumed to arise from traumatic implantation of epidermal fragment, but the pathogenesis is still controversial. Recently, with microscopic findings, immunohistochemical features, and molecular studies, the epidermoid cysts of the sole may be induced by the human papillomavirus. We report two cases of epidermoid cysts of the sole with the discussion of the pathogenesis.

PURPOSE: To determine the effect of polyurethane with sustained release dexamethasone in delayed adjustable strabismus surgery in rabbits. METHODS: After recession of the superior rectus muscle(SRM), balanced salt solution or polyurethane film with/without sustained release dexamethasone was applied beneath and over the SRM in the control group(group C), polyurethane-steroid group(group P-S) and polyurethane group(group P), respectively. Delayed adjustment was performed once on each SRM at four and six weeks postoperatively by a masked observer. The possible length to adjust and the necessary force required for the adjustment, as well as the degree of any adhesions, were also evaluated. RESULTS: In the control group, adjustment was impossible in all of the eyes at four and six weeks postoperatively. In group P-S, adjustment was possible in 11 out of 11(11/11) eyes four weeks postoperatively and in 10/11 eyes six weeks postoperatively. In group P, adjustment was possible in 9/11 eyes four weeks postoperatively and in 10/12 eyes six weeks postoperatively. In addition, the degree of adhesion was significantly less in group P and in group P-S compared to the control group. The degree of adhesion between the SRM and the sclera was marginally better(p=0.051) in group P-S four weeks postoperatively than in group P. CONCLUSIONS: Use of polyurethane film could delay adjustment in most of the rabbit eyes for up to six weeks postoperatively. Sustained release dexamethasone is helpful for delaying adjustment in rabbit eyes until six week postoperatively without the need for frequent topical instillation of steroids.

Revascularizations of 14 occlusive arterial diseases in the lower extremities with the Transluminal Endarterectomy Catheter was done successfully. The causes of occlusions were atherosclerosis in 9 cases and cardiogenic thromboembolism in 5 cases. The site of lesions were at the common femoral artery in 1 case, the superficial femoral artery in 6 cases and the popliteal artery in 7 cases. The length of the lesion were below 5cm(n=3), 5-10cm(n=2), 11-20cm(n=6) and 21-30cm(n=3). Complications were distal embolism(n=1) and hematoma at the puncture site(n=1). No symptoms recurred in any cases during 2 months -15 months followup. Endarterectomy with Transluminal Endarterectomy Catheter was found to be an effective method for revasculizations of occlusive arterial disease in the lower extremity, especially in long segmental occlusion.

Coenzyme Q is concentrated in Golgi apparatus membranes and mitochondria, but not in other membranes. Although it is difficult to prove the metabolic action of coenzyme Q administered exogenously in clinical cases, the effect of this substance can be evaluated by criteria based on clinical findings. In an attempt to evaluate the effect of coenzyme Q for the treatment of 67 patients(male 26 cases, female 41 cases) of congestive heart failure, we administered Coenzyme Q1030mg daily for 4 to 8 weeks. Most of them were valvular heart disease(74.6%) and hypertension (14.9%). Clinical effects were evaluated at least 4 weeks later by the criteria using a scoring method of severity of congestive heart failure which was devised by Ishiyama, etc. In summary, a definite effect was found in 13 cases(19%) and a mild effect was observed in 46 cases(69%). During treatment there were no significant side effects, and also no significant changes in heart rate and blood pressure.

BACKGROUND/AIMS: The endoscopic mucosal resection has now been adopted for a useful modality in both curative therapy and accurate diagnosis of early gastric cancer. A retrospective study was done to evaluate the indication and the limitation of endoscopic mucosal resection of early gastric cancer. METHODS: We studied 20 cases of early gastric cancer treated by endoscopic mucosal resection in Chungnam National University Hospital from November, 1995 to July, 1997. RESULTS: 1) The size affected the curability: 83. 3% of lesions less than 2 cm and 50. 0% of those larger than 2 cm were resected completely. 2) The depth of cancer invasion affected the curability: 87. 5% of lesion confined to mucosa were resected completely, while all of submucosal cancers were resected incompletely. 3) Among fourteen cases resected completely, three cases of lesions larger than 2 cm were residual cancer and two of those less than 2 cm were recurred locally. CONCLUSIONS: To be a curative therapy by endoscopic mucosal resection of early gastric cancer, we think that careful selection of the lesion, that is lesion less than 2cm and confined to mucosa, is necessary

PURPOSE: In this retrospective study, we attempted to evaluate the treatment outcome and the prognostic factors of thymoma treated with surgery, radiotherapy and chemotherapy. METHODS AND MATERIALS: Between 1979 and 1998, 55 patients with thymoma were treated at the Seoul National University Hospital. Of these, 11 patients underwent surgery only, 33 patients received postoperative radiotherapy and 11 patients received radiotherapy only. Twenty-three patients had gross total resection and 21 patients subtotal resection. For postoperative radiotherapy, the radiation dose consisted of 41.4-55.8 Gy. The average follow-up was 64 months, and ranged from 2 to 160 months. The sex ratio was 1:1 and the median age was 48 years (15-74 years). Overall survival and disease-free survival were determined via the Kaplan-Meier method, and the log-rank was employed to evaluate for differences in prognostic factor. RESULTS: The five- and 10-year survival rates were 87% and 65% respectively, and the median survival was 103 months. By univariate analysis, only stage ( p=0.0017) turned out to be significant prognostic factors of overall survival. Also, stage ( p=0.0007) was significantly predictive for overall survival in mutivariated analysis. CONCLUSION: This study showed the stage was found to be important prognostic factors, which influenced survival. Especially, as incomplete resection is related with poor results, complete resection is important to cure the invasive thymoma.

The fatty hamartoma of pericardium is characterized by abnormal accumulations of adipose tissue forming a recognizable mass. We reported a case that could best be put into "fatty hamartoma" group. This 66 year old male presented with atrial fibrillation came in for a anterior mediastinal mass. He received an operation for adenocarcinoma of ascending colon several months ago. The chest CT revealed an inhomogeneous mass in the right anterior mediastinal area, which was not clearly demarcated from the right cardiac border. The heart was deviated to the left side due to the mass. Surgical excision was performed under the impression of cardiac teratoma. The large mass was well encapsulated, and was bright yellow and partly pink, and measured 12x8 cm. Microscopically, the mass consisted predominantly of mature fat cells and abundant fibrous tissue with scattered nests of primitive cardiac muscle cells. Reviewing the literature we found the term "fatty hamartoma" could also refer to rhabdomyolipoma or fibrolipoma. Since it contains entrapped cardiac muscle cells, abundant fibrous tissue, multiple blood vessels and fetal fat cells, it could best the categorized into "hamartoma". The term "fatty" represents it's main component. Therefore we propose the term "fatty hamartoma" that could to be used further.
