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.

BACKGROUND: The purpose of this clinical study was to evaluate the Incentive Spirometry (IS) and Deep Breathing Exercises (DBE) to prevent postoperative pulmonary complications after abdominal surgery in patients over 60 years of age. METHODS: We prospectively randomized 90 patients into 1 of 3 groups: the control group (30 patients) received no respiratory treatment, the IS group (30 patients) was treated with incentive spirometry 4 times daily and DBE group (30 patients) carried out deep breathing exercises under supervision for 15 min 4 times daily. ABGA was taken at ward, PR (preop.room), RR (recovery room), POD1 day and POD2 day. Roentgenographic changes observed at 24 h. and 48 h. after surgery. Pulmonary complications were defined as the development of 3 or more of 6 new findings: cough, sputum, dyspnea, chest discomfort, temperature greater than 38oC, pulse rate more than 100 beats/min. RESULTS: PaO2 in the DBE group and IS group at PR were significantly increased than the values at ward, and the values of the PaO2 in the DBE group at RR and POD1 day, and those of IS group at PR and POD2 day were significant higher than those of the control group (p<0.05). The frequency of development of pulmonary complications (43.3% in the control group, 20% in the DBE group, 20% in the IS group) and roentgenographic changes were comparable in the 3 groups (26.7%, 16.7%, 20% respectively). The DBE group showed the different incidence of postoperative pulmonary complications between upper and lower abdominal surgery (upper: lower= 35.7: 6.3%). CONCLUSIONS: We concluded that DBE and IS were effective in preventing postoperative pulmonary complications after abdominal surgery and lower abdominal surgery causes lesser postoperative pulmonary complications than upper abdominal surgery.

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.
