A case of metastatic malignant melanoma of ovary with malignant melanoma of skin is rare. The tumor was discovered 17months following excisional biopsy of left hand for malignant melanoma of the skin. Primary ovarian malignant melanomas are extremely rare and are thought to originate in teratomas. Ovarian melanoma without evidence of residual teratoma must be considered metastatic even in the absence of a previously identifiable cutaneous or mucocutaneous lesion. We had experienced a case of metastatic malignant melanoma of ovary and presented with a brief review of literature.

PURPOSE: The purpose of this study is to help determine the optimal time and method for operation of pulmonary atresia(PA) with ventricular septal defect(VSD). METHODS: Seventy patients who were diagnosed as PA with VSD in the Pediatric Department of Cardiology, Severance Hospital between May, 1991 and April, 1995, were included in our study. Subjects were divided into two groups depending on the presence of major aorto-pulmonary collateral arteries(MAPCAs). In patients with MAPCAs, the distribution of MAPCAs concerning its relationship with central PA were analyzed, while in patients without them, morphologic changes of PA after performing conventional modified Blalock-Taussig(B-T) shunt were studied. RESULTS: After performing modified B-T shunts, the number of cases of PA stenosis and interruption increased from 26 to 37. Fifteen cases of advanced stenosis and six cases of interrupted PA were also observed. After performing modified B-T shunt, CSAI of both PA was increased from 197+/-101 to 311+/-138, more remarkably in cases without progression of PA stenosis. Among the patients with MAPCAs, 12 cases showed PDA, while 16 cases showed confluent PA. On average, MAPCAs were present in 2.5 cases. Concerning the types of MAPCAs, 14 cases were unifocal, while 36 cases were multifocal and most of them originated from descending aorta. CONCLUSION: In cases where pulmonary flow is maintained by PDA, stenosis of central PA is common, and can result in retarded pulmonary arterial development or increased stricture after modified B-T shunt, so careful attention is needed during follow-up. In cases with dominant MAPCAs, confluent PA is common, and multifocal pulmonary supply renders surgery difficult, so careful analysis of pulmonary supplies to each pulmonary segments, their shapes and relationships, are indicated preoperatively.

BACKGROUND/AIMS: The rate of diagnosis of gastric adenoma has increased because esophagogastroduodenoscopy is being performed at an increasingly greater frequency. However, there are no treatment guidelines for low-grade dysplasia (LGD). To determine the appropriate treatment for LGD, we evaluated the risk factors associated with the categorical upgrade from LGD to high grade dysplasia (HGD)/early gastric cancer (EGC) and the risk factors for recurrence after endoscopic treatment. METHODS: We compared the complication rates, recurrence rates, and remnant lesions in 196 and 56 patients treated with endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR), respectively, by histologically confi rming low-grade gastric epithelial dysplasia. RESULTS: The en bloc resection rate was significantly lower in the EMR group (31.1%) compared with the ESD group (75.0%) (p<0.001). However, no significant difference was observed in the prevalence of remnant lesions or recurrence rate (p=0.911) of gastric adenoma. The progression of LGD to HGD or EGC caused an increase in the incidence of tumor lesions >1 cm with surface redness and depressions. CONCLUSIONS: For the treatment of LGD, EMR resulted in a higher incidence of uncertain resection margins and a lower en bloc resection rate than ESD. However, there was no signifi cant difference in recurrence rate.

PURPOSE: We reviewed the therapeutic results of various Duct-Occlud coils(pfm AG, Koln, Germany) to evaluate the efficacy of the most-recently modified Duct-Occlud coil(Nit-Occlud) in the transcatheter closure of patent ductus arteriosus(PDA), including large defects more than 4 mm in diameter. METHODS: Two hundred and five patients who underwent percutaneous PDA occlusion using Duct- Occlud devices from March 1996 to December 2003 were enrolled and four types of Duct-Occlud [Standard(S), Reinforced(R), Reinforced reverse cone(RR) and Nit-Occlud(N)] were used in this study. The patients were followed up by echocardiogram and physical examination before discharge, one month, six months and 12 months after the procedure. RESULTS: The rate of residual shunt according to the type of Duct-Occlud were as follows: S-54%, R-72%, RR-50%, N-14%(P<0.05 compared with other devices) at one month, S-25%, R-44%, RR- 37%, N-0%(P<0.05 compared with other devices) at six months, S-8%, R-8%, RR-4%, N-0%(P< 0.05 compared with S and R) at 12 months and later. Nit-Occlud coil showed the complete occlusion of PDA after six months of follow-up, even in 12 patients with relatively large PDA(>4 mm). CONCLUSION: The transcatheter closure of PDA using Duct-Occlud was an effective treatment and our study revealed that a Nit-Occlud coil which showed higher rate of occlusion even in PDA with large diameters over than 4 mm, was a more effective modality compared to previous devices.

BACKGROUND: Since the bioavailability of itraconazole capsule is influenced by patients gastric acidity, it results in treatment failure due to its low dissolution and subsequent low absorption when administered in fasting. Itraconazole Melt-Extrusion tablet has been lately developed in order to improve its dissolution profile. It is the first clinical study to evaluate the efficacy and safety of itraconazole Melt-Extrusion tablet in Korea. OBJECTIVE: This study was conducted to evaluate the efficacy and safety of itraconazole melt-extrusion tablet 400mg daily for 1 week(pulse therapy) for hyperkeratotic type of tinea pedis and manus. METHODS: A clinical and mycological investigation was made of 812 outpatients with hyperkeratotic type of tinea pedis and/or tinea manus who had visited at 52 general hospitals under the lead of the Korean Dermatological Association from June to December, 1998. Patients confirmed by clinically and microscopically as hyperkeratotic type of tinea pedis and/or tinea manus were administered 2 tablets twice a day for one week and followed up for 8 weeks from the start of the medication. RESULTS: The results were summarized as follows; 1. Clinical symptoms of hyperkeratotic type of tinea pedis and/or tinea mauns were significantly improved at the end of study, week 8(p<0.001). 2. Clinical response rate, defined as more than 50% decrease of the sum of the clinical symptom scores, was 79.3%(512/646). 3. Mycological cure rate, dafined as both culture and KOH negative at week 8, was 78.2%(244 /312). 4. 40(5.5%) patients, of the 727 patients evaluable for drug safety evaluation, were reported to have adverse event. CONCLUSION: Itraconazole Melt-Extrusion tablet 400mg/day for 1 week (pulse therapy) is effective and safe in the treatment of hyperkeratotic type of tinea pedis and/or tinea manus.
