Kallmann syndrome is characterized by hypogonadotropic hypogonadism resulting from insufficient release of GnRH and associated with anosmia or hyposmia. We experienced two cases of Kallmann syndrome with abnormal brain MRI findings(olfactory bulb aplasia) & secondary sexual dysfunction.

The purpose of this study is to evaluate the stress distribution in the bone around dental implants supporting mandibular overdenture according to the number of implant and the type of attachment. Two or four implants were placed in an edentulous mandibular model and three dimensional photoelastic stress analysis was carried out to measure the fringe order around the implant supporting structure and also to calculate principle stress components at cervical area of each implant. The attachments tested were rigid and resilient type of Dolder bar, Round bar, Hader bar and Dal-Ro attachment. The results were as follows; 1. In 2-implant supported overdenture using Round bar, Hader bar, and Dal-Ro attachment, compressive stress pattern was observed on the supporting structure of implant on loaded side, while tensile stress pattern in unloaded side. 2. In 2-implant supported overdenture using Dolder bar, the rigid Dolder bar shared the occlusal loads between 2 implants in a more favorable manner than was exhibited by the resilient type, while the resilient type placed a more stress on the distocervical area of the implant on the loaded side. But compressive stress pattern was observed in both the loaded and unloaded sides in either case. 3. In 2-implant supported overdenture, rigid and resilient type of Dolder bar exhibited more cross arch involvement than the Round bar, Hader bar, or Dal-Ro attachment. 4. In 4-implant supported overdenture using resilient Dolder bar and Hader bar, stress turned out to be distributed evenly among the implants between loaded and unloaded side, but ther was no reduction in the magnitude of the stress in the surrounding structure of implant contratry to 2-implant supported overdenture.. 5. The stress pattern at cervical area of implant was different with the number of implant or the type of attachment but the overload, harmful to surrounding structure of implant, was not observed.

Purpose: this study was to evaluate the fitness of adjustable dental impression trays on the Koreans : the trays used in the previous study by Kim et al. as part of the dental adjustable tray development project were improved and modified. Material and method: The patterns of tray were made through CAD-CAM process, and a simple silicone-base molds were made from them. The trial products were reproduced by pouring polyurethane into these molds. 30 male students(Wonkwang University, Dental College) and 30 female students (Wonkwang Health Science College, Department of Dental Hygiene) were selected and Reversible hydrocolloid impression materials were used for this study. The fitness of the trays was evaluated by measuring the width and length of impression materials of each measurement sites. Results and conclusion: 1. In adapting the trays inside the mouth, a uniform width of impression material(3.6mm) was obtained in most sites due to the tooth stops and the inclined planes accommodating the width of the tray. 2. The thickness of impression material in the central part of the palate was a mean 9.8 mm, which turned out to be somewhat thick. 3. In the mandible, the thickness of the impression material in the lingual side inferior to the contact point of the 1st and 2nd molars was 2.7mm, and the thickness of the material in the lingual side of the rearmost margin was 2.5 mm. The thickness of the impression material of these areas was relatively thin.

PURPOSE: To evaluate the specific findings of angiography for various causes of gastrointestinal bleeding. MATERIALS AND METHODS: We retrospectively analyzed 35 patients of gastrointestinal bleeding detected by angiography, between April 1987 and July 1993. There were 28 men and 7 women, 19 to 83 years old (mean, 47 years). Of these 35 cases of gastrointestinal bleedings, there were 12 gastric bleedings, 4 duodenal bleedings, 9 small intestinal bleeings, 6 ileocecal bleedings, and 4 large intestinal bleedings. RESULTS: Of 35 cases, we could diagnose the specific cause of bleeing in 13 patients (37%) by angiography. Of these 13 cases, there were 4 cases of gastric ulcers showing contrast pooling in ulcer crater, 5 cases of vascular malformations showing anomalous vascular mass with early dilated venous drainage, 2 cases of direct invasion of hepatocellular carcinoma showing invasion of hypervascular mass into small bowel, one case of pseudoaneurysm at gastroduodenal artery in a patient of acute pancreatitis, and one case of small intestinal lymphoma showing contrast pooling in a irregular dilated small intestinal lumen. CONCLUSION: in gastrointestinal bleeding, angiography is useful not only in detecting the bleeding site, but also for evaluating the specific causes such as gastric ulcers or vascular malformations.

Acute necrotizing encephalopathy is a recently established disease entity, proposed by Mizuguchi et al in 1995, that shows a characteristic symmetric and multifocal involvement of both thalamus, brainstem tegmentum, cerebral periventricular white matter, and cerebellar medulla. It is known to be prevalent in Japan and other Far Ease countries. The etiology of the acute necrotizing encephalopathy remains unknown. The typical course of acute necrotizing encephalopathy is the development of the irreversible neurologic symptoms related to brain lesions. The diagnosis can be made on the basis of the combination of a typical clinical profile and characteristic radiologic findings. We experienced a first case of acute necrotizing encephalopathy in a 9 month old boy in Korea. We report this case with the brief review of related literatures.

A 14-old girl presented to the general hospital with a fracture of the proximal metaphysis of the right humerus. Conventional radiography, CT and MR imaging revealed simple bone cyst of the right humerus. Percutaneous autologous marrow and MIIGTM115 injection into simple bone cyst were performed under general anesthesia. But the patient did not fully regain consciousness and showed no response to central pain. The post-interventional cardiac echocardiogram demonstrated pulmonary embolism. Despite subsequent thrombolytic therapy, the patient died 1hour later. The legal autopsy was performed at National Institute of Scientific Investigation.
