Five cases of cerebral arteriovenous malformation(AVM) are presented, which underwent total extirpation using the operating microscope. The following are considerations which favor the total extirpation of AVM and the advantages of using the operating microscope, including the rationale for non-use of hypotensive anesthesia or mannitolization which is commonly used in intracranial aneurysm surgery: 1) Relatively small sized AVMs are found to show a high rate of large intracerebral hematoma, including that the degree of bleeding from the malformed vessels is not related to the size of the AVM. 2) The operating microscope facilitates the following procedures: a) determination of the extent of the malformed vessels. b) clipping feeders. c) identification of red vein and laminar flow. d) preservation of normal brain tissue.

In 1921, Dandy discussed the clinical diagnosis and treatment of hydrocephalus secondary to occlusion of the foramina of Magendie and Luschka. In 194, Walker reported a case of congenital atresia of the outlets of the fourth ventricle treated surgically. Since a detailed study of this disease entity by Benda in 1954, the condition has commonly been known by the term, the Dandy-Walker syndrome. In 1968, Raimondi and et al refered this condition as the Dandy-Walker cyst. There is considerable discussion as to the nature of the fundamental embryologic error in this condition, but Denda suggested that atresia of developing fourth ventricular foramina was only a part of the syndrome and not its cause, because in some cases reported, the foramina were found to be patent. These patients. Show characteristic clinical symptoms, signs and radiological findings and should suggest the correct diagnosis. This syndrome was one of the first cause of hydrocephalus to be treated successfully by surgery. We are reporting one case of this cyst encountered recently at Yonsei University Medical Center.

Nickel is widely known throughout the world as a common source of contact dermatitis. Korea is one of the rapidly developing countries where the use of nickel and nickel by-products is on the rise. Lacking in ore, Korea imports most of its nickel. In the last ten years, in relation to rapid industrial development, the amount of nickel imported has increased over 1, 000 times. Nickel dermatitis is becoming an increasing problem in the patch test clinic. With regards to this, we have tried the dimethylglyoxime spot test to all materials mentioned in the textbooks which are regarded as nickel sources in other industrialized societies, so as to make an up-to-date list of nickel sources applicable to Korea. In addition, we have also included traditional nickel sources such as acupuncture needles, fire pot, old and new coins and chest of drawers etc. We also have analyzed data concerning nickel imports to Korea during the past 10 years.
