The purpose of this study was to evaluate the in vitro antifungal effect of several kinds of denture lining materials containing nystatin and silver-zeolite on Candida albicans. Three commercially available tissue conditioners (Soft-Liner, Coe-Comfort, Coe-Soft) and two direct denture relining materials (Tokuso Rebase, Durabase) were selected. In terms of the zone of inhibition and some basic physical properties, I could find the following results ; 1. Nystatin or silver-zeolite included in those relining materials had definite antifungal activities against the Candida albicans. 2. As times went on, both of the antifungal agents's activities decreased gradually. 3. Antifungal agents did not affect the relining materials' basic physical properties. 4. Direct chairside relining materials showed unfavorable dark discoloration with response to sil-ver-zeolite.

Keratosis punctata of palmar creases has been considered an uncommon variant of keratosis punctata, which itself is considered rare condition. Clinically our case, 32-year-old seaman, shows cup-shaped depression of the epidermis of varying size, from 1-3mrn in diameter, limited to the large flexor creases of the palms and digit. The histologic features are hyperkeratotic and slight acanthotic central epidermal depression without parakeratosis and loss of granular layer. A sparse mononuclear infilterate are seen arround the capillaries in the dermal papillas. No relationship to arsenical agents, syphilis, or genetic factors can be ascertained by history.

A case of sacrococcygeal chordoma diagnosed by fine needle aspiration is presented. This is a case of a 54-year-old woman who came with coccygeal pain of 5-6 months duration. Aspiration biopsy cytology revealed many nests of cells having abundant bubbly cytoplasm and round to oval variably sized nuclei. The cells had indistinct cytoplasmic borders and many of the cells had cytoplasmic vacuoles. The nuclei had thin regular nuclear membranes, finely granular chromatin and one or two small nucleoli. The cells were generally monotonous, but focally pleomorphic with giant cell formation. Mitotic figures were scanty. The backgroud of the aspirate contained abundant mucinous materal. These findings were typical of those of recorded chordoma cases and the diagnosis was confirmed by a following open biopsy. The patient received 4,000 rads of neutron radiotherapy and has been well till March '88.

Fine needle aspiration cytologic findings of four cases of chondrosarcoma were described. The cases consisted of one primary scapular tumor, two recurrent shoulder masses, and right upper quadrant mass which developed after an A-K amputation for an unknown tumor. The aspirates characteristically revealed cell-rich smears containing clusters and isolated cells having abundant cyanophilic cytoplasm and round to oval or elongated vesicular nuclei. The cytoplasm was occasionally foamy. The nuclei were usually small but prominent. Nuclear atypism and pleomorphism were frequently associated. The last case showed epithelioid sheets of polygonal cells, possibly representing chondroblasts, and a well differentiated chondroid element. The fine needle aspiration could be a good diagnostic tool for primary, recurrent, and metastatic chondrosarcomas.

BACKGROUND: Calcinosis cutis may occur when connective tissue is abnormal (dystrophic), or where calcium or phosphate levels in the blood are high(metastatic); alternatively, there may be no obvious underlying cause(idiopathic). The exact incidence of calcinosis cutis in dermatologic patients is not well-kniown and the pathomechanism of it remains to be elucidated. OBJECTIVE: This study was performed to analyze the incidence, clinical and histopathological features of calcinosis cutis. METHODS: We studied 72 patients with calcinosis cutis who visited our department between January 1985 and December 1996. The patients were classified into 3 types (dystrophic, metastatic, and idiopathic) and were analyzed clinically and histopathologically. Results : The results were summerized as follows; 1. There were 60 cases(83.3%) and 12 cases(16.7%) of the dystrophic and idiopathic types, respectively but the metastatic type was not observed. The frequency of dystrophic calcification in individual disorders was 88.2% in pseudoxanthoma elasticum, 66.7% in trichilemmal cyst and dermatomyositis, and 64.6% in pilomatrichoma. 2. In the idiopathic type, it was common in females aged over 50 years and the mean duration of lesions was 2.8+/-2.0 years. The predilection site was the flank(5 cases) and most of the lesions(7 cases) showed skin-colored nodules 3. Histopathologically, calcified material of the idiopathic type was located predominently in the dermis(10 cases) and was present as large masses surrounded by a foreign body reaction. 4. In the dystrophic type, calcified deposits were noted predominently within the shadow cells of pilomatricoma, in the degenerated elastic fibers of pseudoxanthoma elasticum, and in the keratinized area of basal cell carcinoma, squamous cell carcinoma, trichilemmal cyst, and epidermal cyst. Foreign body reactions with giant cells and mononuclear cell infiltrations were often found around large deposits of calcium. Conclusion : The incidence of calcinosis cutis in dermatologic patients is relatively low, but a variety of disorders can be associated with cutaneous calcification. Therefore, dermatologists should be familiar with the different forms of cutaneous calcification and the dermatoses that manifest them.

OBJECTIVE: The authors evaluate the differences in the pedicle screw pull-out strength between an unaugmented screw and a screw augmented by high pressurized PMMA in an embalmed human lumbar cadaveric spine. METHODS: Pedicle screws were inserted in the 50 pedicles of cadaver lumbar spine after measuring the bone mineral density(BMD) of the specimens. The pedicle screw was inserted without augmentation on the left pedicle and with augmentation by a vertebral reconstruction with high pressurized PMMA on the right side. The pedicle screw was inserted before the hardening of bone cement on the right side. A computed tomographic scan was done to evaluate the location of the PMMA and PMMA/ screw interface. After that, a screw pullout strength test was performed. RESULTS: There were positive correlations between the pull-out strength and BMD in the control group (r=0.7339). The average pull-out strength of the augmented group was 168% greater than that of the control group(p<0.05). The pull-out strength of the augmented group was correlated with in the volume of the PMMA. CONCLUSION: A pedicle screw that is augmented with PMMA will provide a more rigid fixation than that of an unaugmented screw, especially in the low BMD group of the specimens.

Since the treatment of edentulous patients with osseointegrated implant was first introduced more than 30 years ago, implant therapy has become one of the most important dental treatment modalities today. Based on the previous experience and knowledge. Branemark Novum(R) protocol was introduced with the concept of simplifying surgical and prosthetic technique and reducing healing time recently. This protocol recommends the installation of three 5mm wide diameter fixtures in anterior mandible and the prefabricated titanium bars for superstructure fabrication. This study was designed to analyze the stress distribution at fixture and superstructure area according to changes of fixture number, diameter and superstructure materials. Four 3-dimensional finite element models were fabricated. Model 1 - 5 standard fixtures (13mm long and 3.75mm in diameter) & superstructure consisted of type IV gold alloy and resin Model 2 - 3 wide diameter fixtures (13mm long and 5.0mm in diameter) )& superstructure consisted of type IV gold alloy and resin Model 3 - 3 wide diameter fixtures (13mm long and 5.0mm in diameter) )& superstructure consisted of titanium and resin Model 4 - 3 wide diameter fixtures (13mm long and 5.0mm in diameter)& superstructure consisted of titanium and porcelain A 150N occlusal force was applied on the 1st molar of each model in 3 directions-vertical(90degree)horizontal(0degree)and oblique (120degree). After analyzing the stress and displacements, following results were obtained. 1. There were no significant difference in stress distribution among experimental models. 2. Model 2,3,4 showed less amount of compressive stress than that of model 1. However, tensile stress was similar. 3. Veneer material with a high modulus of elasticity demonstrated less stress accumulation in the superstructure. Within the limits of this study.Branemark Novum(R) protocol demonstrated comparable biomechanical properties to conventional protocol.

The management of LcP disease is dependent on the prognosis yet. This may be difficult to predict for the individual child, particularly at the onset of the disease when radiological sign may be minimal. But some form of conservative treatment is generally commenced before the prognosis become apparent. The purpose of this study was to determine the validity of Catterall's grouping and value of other radiological and clinical factors in predictiong prognisis and also the correlation between the clinical and radiological results at the conclusion of the pathological precess in LCP disease. Between the clinical and radiological results at the conclusion of the pathological process in LCP disease. Between June 1986 and July 1995, 64 childrens with LCP disease were tearted in Kyungpook University Hospital, 44 hips of 40 childrens who had adequate clinical and radiological data were reviewed. The average follow-up period was 5.4 years. The results obtained were followings: 1.The mean age at first visit or diagnosis was 6.7 years. 2. Of 40 childrens, 4 childrens had bilateral involvement. Boys were more predominat. 3. The degree of uncovering of femoral head and medial joint space at the presentation seemed to be prognostic factor for the end results. 4. Catterall & lateral pillar classification seemed to be difficult at presentation of the disease but also an important guide to determine the prognosis.
