Enchondromas generally occur in the hand and uncommonly in the long bones. Because enchondromas are usually asymptomatic, most are discovered during diagnostic radiology for another disease. Here, we describe a case of enchondroma in the right humerus in a 79-year-old female patient with concomitant rotator cuff tear arthropathy. The patient was initially hospitalized for prolonged pain and pseudoparalysis of the right shoulder. The condition, which was histologically confirmed as an enchondroma in the proximal humerus, was treated with curettage and reverse total shoulder arthroplasty. In this case report, we present a rare case of an enchondroma with combined rotator cuff tear arthropathy.

From January 1971 to December 1980 the authors observed 165 cases of chronic ulcers of the extrernities in the Department of Dermatology, Chonnam University Hospital. The results obtained can be summarized as follows. 1) During this period, the mean average percent of ulcer patients seen was 0.41 of the yearly total patients. 2) The ages of onset was quite varied with the highest group in the 5th decade. The ratio of men to women was 2.93: 1. 3) The most common predilection site was right lower extremity. 4) Leprosy, especially T-type, was the most comrnon underlying disease.

We presented here a case of an 80-year-old male patient who was, confirmed in the typical tumor stage of Mycosis fungoide by skin biopay. Relatively well-defined, brown-colored, round patches were found about 3 years ago on the chest, abdomen and inguinal area. He had received some treatment at several private clinics uder the impression of seborrheic dermatitis, paoriaais and eczematoid dermatitis. However, the skin manifestations were not improved t.ut rarther increased in eize, similarly to tinea corporis. Two months ago, firm nodules and tumors developecl a new on the lesinn sites, assoviated with intense pruritus and ulcerative tendency. We tried radiation therapy, but due to old age the patient chose to discontinurue.

Most of the malignant tumors of the pancreas are adenocarcinomas arising from the ductal epithelium. Primary leiomyosarcoma of the pancreas, even though it is the most common sarcoma of the pancreas, is very rare. We present a case of leiomyosarcoma of the pancreas, probably primary, with metastases to the stomach, lymph nodes, and abdominal wall. A 52-year-old woman visited the hospital with vague right upper abdominal pain and weigh loss of 6 kg for 2 months. The radiological and endoscopic examination revealed that she had a large heterogeneous mass, 11 cm in size, in the pancreatic body and tail, a 4 cm-sized mass in the paraaortic area, and a 3 cm-sized polypoid mass in the stomach. Histologically, they were all similar to one another and composed of markedly pleomorphic cells. Immunohistochemical and electron microscopic studies showed definite smooth muscle differentiation of the tumor cells. Two months later, the patient underwent an excision of a new 3 cm mass in the right lower abdominal wall, showing features of well differentiated leiomyosarcoma.

STATEMENT OF PROBLEM: Zirconia-based restorations have the common technical complication of delamination, or porcelain chipping, from the zirconia core. Thus the shear bond strength between the zirconia core and the veneering porcelain requires investigation in order to facilitate the material's clinical use. PURPOSE: The purpose of this study was to evaluate the bonding strength of the porcelain veneer to the zirconia core and to other various metal alloys (high noble metal alloy and base metal alloy). MATERIAL AND METHODS: 15 rectangular (4x4x9mm) specimens each of zirconia (Cercon), base metal alloy (Tillite), high noble metal alloy (Degudent H) were fabricated for the shear bond strength test. The veneering porcelain recommended by the manufacturer for each type of material was fired to the core in thickness of 3mm. After firing, the specimens were embedded in the PTFE mold, placed on a mounting jig, and subjected to shear force in a universal testing machine. Load was applied at a crosshead speed of 0.5mm/min until fracture. The average shear strength (MPa) was analyzed with the one-way ANOVA and the Tukey's test (alpha= .05). The fractured specimens were examined using SEM and EDX to determine the failure pattern. RESULTS: The mean shear strength (+/- SD) in MPa was 25.43 (+/- 3.12) in the zirconia group, 35.87 (+/- 4.23) in the base metal group, 38.00 (+/- 5.23) in the high noble metal group. The ANOVA showed a significant difference among groups, and the Tukey's test presented a significant difference between the zirconia group and the metal group. Microscopic examination showed that the failure primarily occurred near the interface with the residual veneering porcelain remaining on the core. CONCLUSION: There was a significant difference between the metal ceramic and zirconia ceramic group in shear bond strength. There was no significant difference between the base metal alloy and the high noble metal alloy.

Ultrasongraphy is a safe, noninvasive examination which should be the first procedure in the workup of apatient with a definite or suspected pelvic masses. The diagnostic schemes were derived from correlating the sonographic features with histomorphology in 230 surgically proven pelvic masses. Besides separating pelvic masses into the conventional categories of cystic, complex and solid, grayscale sonographic features of a pelvic mass canbe used to subcategorized these masses into a more useful differential diagnosis. The results are as follows; 1.The most characteristic finding of uterine myoma was midly to mederately echogenic uterine enlargement (90.7%)with a lobulated uterine margin (62.8%), and often less echogenic than the normal uterine echoes. 2. The typical ultrasonographic finding of H-mole was uterine enlargement with multiple small vesicular patterns of intrauterincontents(93%). 3. The most frequent finding of cystic teratoma was cystic mass with echogenic foci(48%), but the echogenic appearance of the lesions was extremely variable. 4. The ultrasonographic findings of ectopic pregnancywere adnexal mass(comlex or cystic), decidual proliferation of the uterus, enlargement of uterine size, fluid incul-de-sac, deveiation of uterus by adnexal mass, and psuedointrauterine appearance. 5. Ultrasound provided information leading to the correct diagnosis in 57% of cases, contributory data in 21.3%, and non-specific information in 10.4%. Errors occured in 3.9% and false-negative in 7.4%.

PURPOSE: Few studies are available on the role of female urethral length (UL) and anterior vaginal wall thickness (AVWT) in stress urinary incontinence (SUI). The aim of this study was to evaluate the usefulness of characterization of female UL and AVWT associated with SUI. MATERIALS AND METHODS: Between May 2006 and October 2006, a total of 53 women with or without SUI were included in this study. Twenty-three women with SUI and 30 healthy volunteers serving as controls underwent transvaginal ultrasound with use of a 7.5MHz transrectal probe. Measurement comprised UL and three portions of AVWT classified as proximal, middle, and distal according to the location against the urethra. RESULTS: The women's median age was 51.1 (range: 30-73) years. The UL (mm, mean+/-SD) was significantly shorter in women with SUI than in women without SUI (28.7+/-2.8 vs 31.2+/-4.5, respectively, p=0.02). The AVWT of women with SUI (mm, mean+/-SD) was 16.2+/-2.8 in the proximal, 10.7+/-1.9 in the middle, and 9.3+/-2.0 in the distal portion, and those of women without SUI were 16.8+/-3.2, 10.1+/-1.8, and 6.9+/-1.3, respectively. Distal AVWT was significantly thicker in women with SUI than in women without SUI (p=0.01). There were no significant differences in AVWT or UL between pre- and postmenopausal women. A significant positive correlation was found between advancing in age and decrease in UL (p=0.03). Body mass index and parity showed no correlation with UL or any AVWT (p>0.05). CONCLUSIONS: These results suggest that women with shorter UL and thicker distal AVWT are likely to have SUI. Furthermore, UL was shorter in older women.

PURPOSE: To evaluate the diagnostic efficacy of three-dimensional(3D) short-range MR angiography(MRA) andmultiplanar reconstruction(MPR) imaging in hemifacial spasm(HS). MATERIALS AND METHODS: Two hundreds patientswith HS were studied using a 1.5T MRI system with a 3D time-of-flight(TOF) MRA sequence. To reconstructshort-range MRA, 6-10 source images near the 7-8th cranial nerve complex were processed using a maximum-intensityprojection technique. In addition, an MPR technique was used to investigate neurovascular compression. We observedthe relationship between the root-exit zone(REZ) of the 7th cranial nerve and compressive vessel, and identifiedthe compressive vessels on symptomatic sides. To investigate neurovascular contact, asymptomatic contralateralsides were also evaluated. RESULTS: MRI showed that in 197 of 200 patients there was vascular compression orcontact with the facial nerve REZ on symptomatic sides. One of the three remaining patients was suffering fromacoustic neurinoma on the symptomatic side, while in two patients there were no definite abnormal findings. Compressive vessels were demonstrated in all 197 patients; 80 cases involved the anterior inferior cerebellarartery(AICA), 74 the posterior cerebellar artery(PICA), 13 the vertebral artery(VA), 16 the VA and AICA, eight theVA and PICA, and six the AICA and PICA. In all 197 patients, compressive vessels were reconstructed on one 3Dshort-range MRA image without discontinuation from vertebral or basilar arteries. 3D MPR studies providedadditional information such as the direction of compression and course of the compressive vessel. In 31 patientsthere was neurovascular contact on the contralateral side at the 7-8th cranial nerve complex. CONCLUSION: Inpatients with HS, 3D short-range MRA and MPR images are excellent and very helpful for the investigation ofneurovascular compression and the identification of compressive vessels.
