I experienced a case of a congenital intramural cyst of the uterine fundus. On examination by light and electron microscope it was composed of a single layer of thin atrophied lining epithelium without secretory activity and was found to be derived from the paramesonephric duct. This case is presented with a brief review of the literature.

The use of a cast-brace in the treatment of tibial fractures was first applied by the authors since 1964 in an attempt to prevent stiffness of the knee resulted from prolonged cast immobilization. The authors attempts on all 43 cases throughout the experimental period were proved satisfactory, among which, however, only a few case showed unwanted result such as delayed union in the early clinical experience.

PURPOSE: The aim of this study was to determine differences in shear bond strength to human dentin using immediate dentin sealing (IDS) technique compared to delayed dentin sealing (DDS). MATERIAL AND METHODS: Forty extracted human molars were divided into 4 groups with 10 teeth each. The control group was light-cured after application of dentin bonding agent (Excite(R) DSC) and cemented with Variolink(R) II resin cement. IDS/SE (immediate dentin sealing, Clearfil(TM) SE Bond) and IDS/SB (immediate dentin sealing, Adapter(TM) Single Bond 2) were light-cured after application of dentin bonding agent (Clearfil(TM) SE Bond and Adapter(TM) Sing Bond 2, respectively), whereas DDS specimens were not treated with any dentin bonding agent. Specimens were cemented with Variolink(R) II resin cement. Dentin bonding agent (Excite(R) DSC) was left unpolymerized until the application of porcelain restoration. Shear strength was measured using a universal testing machine at a speed of 5 mm/min and evaluated of fracture using an optical microscope. RESULTS: The mean shear bond strengths of control group and IDS/SE group were not statistically different from another at 14.86 and 11.18 MPa. Bond strength of IDS/SE group had a significantly higher mean than DDS group (3.14 MPa) (P < .05). There were no significance in the mean shear bond strength between IDS/SB (4.11 MPa) and DDS group. Evaluation of failure patterns indicates that most failures in the control group and IDS/SE groups were mixed, whereas failures in the DDS were interfacial. CONCLUSION: When preparing teeth for indirect ceramic restoration, IDS with Clearfil(TM) SE Bond results in improved shear bond strength compared with DDS.

Oblique single-plane trochanteric osteotomy, in which an oblique cut is made through the femoral trochanteric area and the bony fragments are rotated at the face of the cut in direct contact with each other, allows simulatenous correction of the femoral neck-shaft angle, femoral anteversion as well as flexion/extension effect. Only approximate methods of calculating the correction effects of this procedure have been introduced. Considering unique spatial orientation of femoral neck, we developed a rigorous method to calculate preoperatively the obliquity of the single-plane osteotomy and the amount of rotation required to achieve the target femoral conformation, through geometric analysis. The correction effect by oblique trochanteric osteotomy on the geometry of proximal femur was dependent not only on the amount of change of the neck-shaft angle and femoral anteversion but also on the preoperative neck-shaft angle and femoral anteversion themselves. The flexion/extesion effect was determined by the direction of the correction and the preoperative neck orientation. Computer graphic simulation study confirmed the validity of this method. A program written in QBASIC was introduced to make this complex calculation method more useful in the clinical practice.

Desmoid tumor is a type of fibromatosis usually arise in deep musculo-aponeurotic structures, primarily of the trunk and extremities. It is characterized by proliferation of fibroblastic tissue and does not metastasize but may be locally aggressive. Eventhough the surgical margin reveals clean, recurrence often occurs. To analyze the extent of the tumor and homodynamic characteristics exactly, we performed IV bolus CT. Desmoid tumors show peripheral rim enhancement on early phase scan and more strong, central enhancement on late phase IV bolus CT, which reflects abundant fibroblastic components of the tumor. We report two cases of pathologically confirmed desmoid tumor performed IV bolus CT.

This study was done on 171 volunteers in order to investigate the present status of cutaneous normal flora of Candida species and the distribution of Candida species on the normal human skin in dermatologic clinic of Korea University Hospital from January, ]984 to December, 1984. Among the 171 volunteers, 115 strains of Candida species were identified by culture on the Sabouraud's dextrose agar media, germ tube test, sugar assimilation test, sugar fermentaion test and culture on corn meal with Tween 80 media, The results were summarized as follows: 1. The incidence of cutaneous normal flora of Candida species was 13, 5,5 (115 species among 855 sites) 2. Candida species were distributed in oral cavity(45 species), 4th interdigital toe web(39 species), groin(12 species), axilla(11 species) and 4th interdigital finger web(8 species) in order of frequency. 3, Of ll5 species, 45 species were cultured in summer, 27 species in autumn, 18 species in winter and 14 species in spring. 4 Of 115 Candida species, C. albicans(88 species), C. parapsilosis(12 species), C, tropicalis(8 species), C. guilliermondii(3 species) and C. stellatoidea(2 species) were identified. Two species could not be identified.

Congenital ectodermal dysplasia are a group of familial disorders that affect tissues and organs of ectodermal origin to varying degrees. It devided hidrotic type and anhidrotic type by geneologic origin and distinct clinical manifestationa. The hidrotic type usually trait by autosomal dominant gene and manifested dystrofic nails, defect of hair and eyebrow and palmoplantar hyperkeratosis. This patient is 16 year oId male. He had been dystrophic nails, alopecia since at birth, thereafter palmoplantar hyperkeratosis, clubbing fingers noted. C.R.C. Urinalysis, stool examination, chest x-ray were within normal limit. Biopsy specimen from palm revealed hyperkeratosis, hypergranulosis, acanthosis and, mild inflamrnatory cell infiltrate on upper dermis. Biopsy speeimen from the scalp revealed norrriaI findings except slight hypoplasia of ebaceaus gland.

BACKGROUND: Rapid progress in medical science and technology has lengthened the average span of life in general population and accelerated the increase in the elderly. This gave rise to the expansion of chronic degenerative disease in the elderly, and then led to an increase in the utilization rate of health care facility and medical fee in sequence. METHODS: In order to grope for an effective control program of chronic degenerative disease and to find out the characteristics of disease structure and utilization patterns of health care facility in the elderly, the author analysed the 6,072,196 cases of insured medical record of Federation of Korean Medical Insurance Societies from January 1st to December 31st of the year 1991. RESULTS: Essential hypertension(5.94%) is the most common disease in the elderly. And what follows are gastritis and duodenitis(4.29%), acute bronchitis and bronchiolitis(3.68%), acute upper respiratory infection of multiple or unspecified site(3.47%) and diabetes mellitus(3.21%). Twenty most frequent diseases constitute the top 50.27% and one hundred constitute over 85% of all frequency of health care facility utilization. There are different patterns of diseases between two sexes. Pulmonary tuberculosis, chronic liver disease and cirrhosis, malignant neoplasm of stomach, chronic obstructive pulmonary disease, occlusion of cerebral arteries, sprains and strains of knee and leg, malignant neoplasm of trachea, bronchus and lung, other open wound of head, erythematosquamous dermatosis are more than 1.5 times higher in male by the standardized frequency ratio. There is a significant dissimilarity of disease structure between primary and other types of health care facility, which presents the point of reinforcement in primary care. The author has also noted elderly patients prefer secondary or tertiary health care facility in case of essential hypertension, diabetes mellitus, pulmonary tuberculosis, heart failure, duodenal ulcer, chronic liver disease and cirrhosis, funtional gastrointestinal disorder, hypertensive heart disease and chronic obstructive pulmonary disease which seems to be not so critical in most cases. CONCLUSIONS: Patients of chronic degenerative disease tend to pursue the high quality of medical care and irregularly utilize health care delivery system.
