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.

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.

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.

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.

In order to evaluate the safe ligation time and sites of dural venous sinuses during neurosurgical operation, systemic arterial pressure(SAP), cerebral perfusion perssure(CPP), intracranial pressure (ICP) and intrasinal pressure(ISP) were measured in cats through neuromonitor before and after obstruction of anterior 1/3, middle 1/3, posterior 1/3 of the superior sagittal sinus and the results were as follows. There were no significant increases of pressures after obstruction of anterior 1/3 of the superior sagittal sinus. In the obstructed middle 1/3 of the superior sagittal sinus group, signifi6int increases were seen un the m-SAP within 2, 4 and 6 minutes, the m-ICP within 2-7 minutes, the r.i-ISP within 14 minutes after obstruction. In the -obstructed posterior 1/3 of the superior sagittal sinus group, there were significant increases of m-SAP within 2, 4 and 6 minutes, the m-ICP within 27 minutes, the m-ISP within 13 minutes. In the obstructed Torcular Herophili,group, there were significant increases of the m-SAP within 1-2 and 4-7 minutes, the m-ICP within 36 minutes and the m-ISP within 1-7 minuted and less significant dercreases of the m-CPP within 5-7 minutes after obstruction. In the obstructed right transverse sinus group, significant increases of the m-ICP and the m-ISP were seen within 1-7 minutes after obstruction. there were no remarkable changes in the obstructed left transverse sinus group.

Ectopic liver in the umbilicus is very rare, and a few cases have been reported in the world. It is thought that an increased intraabdominal pressure resulting in entrapment of liver cell nests causes the presence of liver in the umbilicus. It relates to neonatal problem such as infection. We report a case of ectopic umbilical liver in a stillborn male of 28 gestational weeks. His mother discovered loss of fetal movement 2 days before admission, and intrauterine fetal death was diagnosed by ultrasonography. Grossly, the umbilical cord was markedly swollen. On cut section, a well circumscribed, oval round, tan-colored soft mass was noted within the cord. Histologically, it consisted of hepatic cords without bile ducts. The umbilical vessels were distorted by the ectopic liver, and contained thrombi. These findings suggest that ectopic umbilical liver results in the intrauterine fetal death

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.
