Technique and problems of total parathyroidectomy with autotransplantation in secondary hyperparathyroidism

続発性上皮小体機能亢進症20症例に対して, 上皮小体全摘除術および自家移植術を施行した.6症例に再発がみられたが, このうち3症例は局麻下に移植片を摘出し再発に対しての治療が容易であったBetween 1982 and 1990, 20 patients with chronic renal failure underwent total para-thyroidectomies and autotransplantations as treatment for secondary hyperparathyroidism. Fourteen cases were cured of their symptoms and their serum PTH levels was restored to normal. Recurrent hyperparathyroidism developed in 6 cases. In 3 of the 6 cases, excision of parathyroid tissue from the forearm could easily be performed under local anesthesia. Of the other cases, 2 had five and one had six glands. Several localizing methods should be performed before operation, in order to overlook the parathyroid glands in different anatomic positions

<臨床>北海道地区の口腔インプラント臨床の現状調査 : 本学卒業生のアンケート調査より

The present study investigated of the situation of oral implant therapy in Hokkaido. Information was obtained with questionnaires mailed to dentists in Hokkaido who are graduates of the Health Sciences University of Hokkaido. A total of 28 of 68 questionnaires were returned (41.2 percent), and all completed surveys were analyzed. The questionnaire asked "How many implant systems are used in your clinic? "The majority of responses was one system (50.0 percent), followed by three (25.0 percent), and two systems (16.7 percent). The most commonly used implant systems were Calcitek (21.1 percent), followed by POI and ITI (15.8 percent), then Branemark, AQB and Platon (10.5 percent). Porcelain fused to metal crowns were used more than resin veneered crowns on implant supported prostheses. At the incisor and canine, porcelain fused to metal crowns were commonly used. At the premolar, porcelain fused to metal crowns were used more often than full cast crowns. At molars, full cast crowns were commonly used. The most common retaining method of prostheses used by dentists was temporary retaining, followed by cement retaining, and screw retaining. The results of this survey suggest that aesthetic treatment is important in present day implant therapy
