With a view to investigating the distribution of keratinophilic fungi in soil according to latitudes in south Korea, soil samples were collected at 81 sites in 17 areas in different latitudes across the country and keratinophilic fungi were isolated by means of Vanbreusegherns technique. The results are summarized as follows : 105 strains of keratinophilic fungi were recovered from 56(69.2%) out of 81 samples. Isolated fungi were composed of 41 strains of Trichophyton ajelloi, 24 stains of Chrysosporium species, 20 strains of Microsporum gypseum, and 20 strains of M. cookei. Frequency of isolation of keratinophilic fungi tended to decrease from higher latitudes down to lower latitudes. In areas of higher latutudes, T. ajelloi and M. cookei were isolated more frequently than in lower latitudes. M. gypseem was most frequent in Cheju City, and Chrysosporium species showed an even distribution, Among three areas under different conditions of moisture and shadedness(i.e., shaded wet, shaded dry, and sunny dry areas), frequency of isolation was highest in shaded dry areas(72.2%). T. ajelloi was the most frequent species in all the three areas, especially in shaded wet areas(53.1%). No M. gypsetcm was found in shaded dry areas. As regards distribution at various sites, roadsides and streamsides exhibited the highest frequency of isolation, and hills the lowest. Except for roadsides, T. ajelloi was the most frequent species at all sites, especially in forests. M. gypseum was frequent at sites beside streams M. cookei at streamsides, fields, and hills and Chrysosporim species in gardens, forests, and streets.

Clinical observations were made on 63 cases on nevus sebaceus of Jadasshon. 52 of 63 cases were diagnosed on the basis of clinical and histopathologic findings during a period of 19 years from January 1969 to July 1987 at the Department of Dermatology, Kyungpook National University Hospital, with the remaining 11 cases diagnosed at other skin clinics in Taegu. Histopathologic examinations were made on 51 selected cases of the 63. The results were as follows : Clinical observations 1) The percentage of patients with nevus sebaceus of Jadasshon of total new outpatients was 0.12%. Of the 63 cases, males numbered 38 and females, 25, with a sex r atio of 1.5: 1. 2) Patients when first seen were most commonly in the age group of 10~19. 3) The most favorate sites were the scalp(83.3%) and face(13.3%). 4) The average size of the lesions was 2.23cm * 3.24cm with no difference among the age groups. Histopathological observations 1) The apparent proliferation of sebaceous glands was observed in 32 of 51 cases(62.7%). The degree of proliferation markedly increased in the age group of l0~19 and slightly decreased beyond this age group. Apocrine glands were present. in 17(33.3%), with a higher number of glands seen in the age group of 10~19. Immature hair follicles were found in 38(74.5%), with no changes according to aging. 2) The epidermal changes such as acanthosis(86.3%), papillomatosis(70.6%), hyperkeratosis(78.2%) and hypergranulosis(78.2%) predominated in the age group of 10-19, and severe but more gradual changes were noted 20 years of age on. 3) Inflammatory cell infiltration of moderate to marked degree was noticeable in 27(53%). The older the patients were, the more pronounced dermal infiltration was. 4) Six of 51 cases were complicated with basal cell carcinoma(3) and syringocystadenoma papilliferum(4). The tumors, which occurred beyond 30 years of age, showed a marked inflammatory cell infiltration.

Traumatic spondylolisthesis of the axis is the fracture of both pedicles and is called commonly as hangman' s fracture. The fractures with the anterior displacement more than 3mm and the angulation, more than 11 degrees were classified as unstable and the surgical methods were recommended for the treatment of the fractures. As for the surgical methods, anterior C2-3 fusion with plate fixation or transpedicular screw fixation were used. However, the differences between the clinical results of both methods were not reported in the literatures. In order to clarisy the clinical results of both methods, the authors evaluated the clinical results of 11 patients treated by anterior plate fixation and 7 patients treated by transpedicular fixation who were operated on between Mar. 1987 and,Jan: 1992. Minimum follow-up period was 12 months. 1. As the surgical complications, two cases of transient dysphagia in anterior fixation group and three cases of malinserted screw in transpedicular fixation group were observed. 2. Limitation of rotatory neck motion, less than 20 degrees in one direction was observed in four cases of transpedicular fixation group. 3. Anterior angulation, more than 10 degrees was noted in three cases of transpedicular group. 4. Mild intermittent neck pain was observed in two cases of anterior fixation group and two cases of transpedicular fixation group. Constant neck pain was present in three cases of transpedicular fixation group. 5. Over-all clinical results were excellent or good in all of anterior fixation group, and in four of seven transpedicular group. Although the clinical materials were limited in number, method of anterior plate fixation was recommended by the authors in the management of traumatic spondylolisthesis of axis, because of the easier technique and the better clinical results than the transpedicular screw fixation.

PURPOSE: To evaluate MRI findings of malignant ovarian tumors. MATERIALS AND METHODS: MRI findings were retrospectively reviewed in 25 patients with surgically confirmed 30 malignant ovarian tumors(common epithelial tumor;23, sex cord stromal tumor;2, endodermal sinus tumor ; 1, metastatic tumor ;4). The findings evaluated were the lesion size, solid and/or cystic component, wall thickness, septal thickness, necrosis, invasion of adjacent organ, ascites, and adenopathy. RESULTS: MRI findings of the malignant ovarian tumors were as follow:Size of lesion was 5-35cm(mean 14cm) ;solid component was present in 80%(24/30);wall thickness was more than 3ram in 90%(27/30);septal thickness was more than 3ram in 70%(21/30);tumor necrosis was present in 40%(12/30%) ;invasion of adjacent organ was present in 76%(19/25);ascites was present in 56%(14/25);lymphadenopathy was present in 24% (6/25). MRI findings of absence of solid component(6/6), even wall and septal thickness(7/7, 19/19) were found only in epithelial tumors. Uneven septal thickness more than 3mm(7/11) was a predominant MRI findings of non-epithelial tumors. Well-defined cystic lesion within solid component was seen in Krukenberg tumors. CONCLUSION: Evaluation of the lesion size, internal architecture, invasion of adjacent organ, ascites, and lymphadenopathy in MRI would enable diagnosis of malignant ovarian tumors and could lead to possible differential diagnosis of epithelial tumors from non-epithelial tumors.

Cholesterol granuloma is thought to arise as the consequence of obstruction of the air cell system. Once the ventilation is blocked, negative pressure builds with mucosal hemorrhage and blood extravasation into the air cell system. And the catabolism of blood releases cholesterol, hemosiderin, lipids and fibrin. It is the foreign body reaction of these products that leads to cholesterol granuloma and cholesterol granuloma cyst formation. The cholesterol granuloma and cholesterol granuloma cyst may develop in any portion of the pneumatic system of the temporal bone and small lesions are commonly encountered in the middle ear and mastoid air cells. But, huge cholesterol granuloma cyst is a unusual lesion and cholesterol granuloma cyst with extensive temporal bone destruction and intracranial extension has been rarely reported. Recently we experienced a case of huge cholesterol granuloma cyst with intracranial extension in a 38-year-old female, and report this case with review of literatures.

We report herein a case of vesicular pemphigoid in a 39 year-old female, who had 1 month history of multiple, pruritic vesicles with erythematous maeules on the whole body, especielly on the flexural surface. The histological findings showed subepidermal vesicle which contained many neutrophils. Direct immvnofluorescent study of perilesional skin revealed linear deposits of C along the dermoepidermal junction and indirect immunofluorescent study revealed linear deposits of immunoglobulin G and Cy along the dermoepidermal junction. Initially, dapsone was tried without any benefit but skin lesions were controlled by a combination therapy of prednisolone and cyclphosphamide.

BACKGROUND: This study purposed to survey the fit rate of respirators by person and by product through conducting a qualitative fit test of high-efficiency respirators; moreover, this study also tests for differences in the fit rates determined by the qualitative fit tests with an increase in the number of the types of respirators tested. METHODS: The subjects of this study were 30 healthcare personnel who had passed a sensitivity test. The fit test of high-efficiency respirators was conducted using FT10 (3M Co., USA), an experimental tool used for performing the qualitative fit test of high-efficiency respirators, and three types of high-efficiency respirators - 1860, PFR95, and N7000 - were tested. RESULTS: The qualitative fit test was performed for the three types of high-efficiency respirators and the fit rate of the respirators that the subjects had been using previously was 43.3%; however, the probability that one or more of the three types of high-efficiency respirators would fit the subjects increased to 83.3%, and this increase was statistically significant (P<0.05). The difference in the fit rates of the three types of high-efficiency respirator types was not statistically significant; however, the differences in the satisfaction of and preference for the different respirator products were all statistically significant (P<0.05). CONCLUSION: Healthcare personnel are using ill-fitting respirators and a qualitative fit test should be performed to improve the fit of their respirator. In the qualitative fit test performed for the high-efficiency respirators, the fit rate increased with the increase in the variety of respirator types. Thus, a large variety of respirators should be made available to increase the fit rate of high-efficiency respirators for healthcare personnel.
