Purpose: Description of a patient with a solitary cyst of the pupillary margin iris pigment epithelium (IPE). Methods: A 63-year-old man referred a suspected iris-ciliary body melanoma in his left eye. Based on both clinical examination and ultrasound biomicroscopy, melanoma was considered unlikely. surgery was under-taken to correct recurrent deterioration of vision due to movement of the lesion across the visual axis. Results: The lesion was excised completely. Ultrasound biomicroscopy and histopathological examination ruled out melanoma and allowed a final diagnosis of primary pupillary margin cyst of the IPE, characterized of pig-mented epithelium, with no connective tissue or vessels. no recurrences or fresh lesions appeared during a one-year follow-up. Conclusions: Primary epithelial iris cysts are usually benign. Treatment is required only in symptomatic patients and those with an uncertain diagnosis. Ultrasound biomicroscopy is indispensable to confirm the clinical diagnosis, follow the clinical course and intervene if surgery is required.

Most pancreatic cancers and extrahepatic cholangiocarcinomas are unresectable at the time of diagnosis, and even in case of a resectable cancer, for elderly or patients with coexistent comorbidities, surgery is.n.t an option. Current treatment alternatives in these scenarios are very limited. Biliary stenting with selfexpanding metal stents(sEMs) is the mainstay palliative treatment of biliary obstruction due to unresectable pancreatic cancer or cholangiocarcinoma. nevertheless, more than 50% of sEMs become occluded after 6 mo due to tumour over- and ingrowth, leading to hospital readmissions and reinterventions that significantly impair quality of life. Regimes of chemotherapy or chemoradiotherapy also provide minimal survival benefits. Therefore, novel therapies are eagerly awaited. Radiofrequency(RF) energy causes coagulative necrosis leading to local destruction of the accessed malignant tissue and has an established role in the treatment of malignancies in several solid organs, especially liver cancers. However, pancreatic and extrahepatic biliary cancers are not easily accessed by a percutaneous route, making the procedure dangerous. Over the past five years, the development of dedicated devices compatible with endoscopic instruments has offered a minimally invasive option for RF energy delivery in biliopancreatic cancers. Emerging experience with endoscopic RF ablation(RFA) in this setting has been reported in the literature, but little is known about its feasibility, efficacy and safety. A literature review makes it clear that RFA in biliopancreatic tumours is feasible with high rates of technical success and acceptable safety profile. Although available data suggest a benefit of survival with RFA, there is.n.t enough evidence to draw a firm conclusion about its efficacy. For this reas.n. prospective randomized trials comparing RFA with standard palliative treatments with quality-of-life and survival endpoints are required. Anecdotal reportshave also highlig

＜正＞ In this paper a new dc-link type wind turbine generator system us.n. a shaft generator system, which is widely used for power sources in a ship, is proposed. The basic configuration of the proposed wind turbine generating system is first explained. And the equations express.n. the system are derived. Then the steady-state characteristics of the generating system are discussed. We use an experimental system that can simulate the characteristics of a wind turbine in this study, because it is hard to operate an actual wind turbine in a laboratory. In addition, the transient responses of this system are investigated when the velocity of the wind is changed. It is shown that experimental results were very close to the simulated ones, supporting the usefulness of the theory.
