As an optimal quality of the restorations, there should be a least amount of seating discrepancy between the casting and abutment teeth. However, high viscosity of the cementing medium and its resulting thickness ay prevent complete seating of the restoration. The use of die spacing material provides adequate internal relief for the cementing medium. The purpose of this study is to compare the thickness of three commonly used die spacing materials. Materials and Methods : Stone plates were fabricated and divided into 12 sections to be painted with die spacers. Tru-Fit, Whip-Mix and Belle de St. Claire die spacer which are commonly used in dental practice were tested in this study. Each die spacers were painted layer by layer according to the manufacturer's recommendation. The average thickness of each die spacers were measured with light microscope(x100) and compared between them. Results and Conclusions: A silver-colored Tru-Fit die spacer has the lowest value of thickness without statistical significance comparing with a gold-colored Tru-Fit die spacer and a gray layer of Whip-Mix die spacer has the highest value of thickness without any statistical significance comparing with Belle de St. Claire die spacer. Three and four layers of Tru-Fit die spacer and two layers of Whip-Mix and Belle de St. Claire die spacers seem to be in the acceptable range of thickness of 25 to 45micrometer for optimal seating of the restorations. The standard experimental design and method should be further evaluated for more consistent and objective results.

A 13-year-old male presented a single, elevated, oval, walnut sized, soft mass on the left retroauricular ares which has increased in size since birth, Histopathologic examination revealed a cyst in the subcutaneus area. Cyst wall is lined by normal epiderrnis and cyst cavity contains hairs and keratinous materials.

The drinking water in apartment is stored in reservoir tank and thereafter supplied each household. In case the drinking water in stored too long or insanitary, tap water might change in quality. This study was carried out to evaluate the physic-chemical and microbiological conditions of 36 samples of tap water of apartments compared to 18 samples of tap water of independence houses in Taegu City from May to October, 1987. Main findings are summarized as follows: PH values were within normal range in all samples. Samples less than 0.2ppm in residual chlorine accounted for 16.7% in the apartment and 5.6% in the independence house. Nitrite nitrogen was detected 2.8% of apartment samples only. Among the total of 54 samples, 11.1% of the apartment and independence samples were over the normal value in standard plate count. Samples more than 1.8 of most probable number (MPN) accounted for 27.8% in the apartment and 33.3% in the independence house. In result of test for residual chlorine, nitrite nitrogen, standard plate count, and MPN, the proportion of the samples revealed inappropriate in respect of drinking water standards. In case of all sorts of tests was 2.7% in apartment and nothing in independence houses, in case of 3 sorts of tests was 2.7% in apartment and 5.6% in independence houses, in case of 2 sorts of tests was 8.3% in apartment and 5.6% in independence houses, and in case of only 1 test was 25.0% in apartment and 22.2% in independence houses. Correlation between residual chorine and standard plate count, and between standard plate count and MPN were observed. It was found that the more years since construction of apartment were, the worse tap water was in quality.

BACKGROUND: The purpose of this study is to evaluate the functional outcomes of reverse total shoulder arthroplasty (RTSA) and to assess factors affecting the patients' subjective satisfaction after RTSA. METHODS: Forty-three patients (mean age, 75.0 ± 5.2 years) who underwent RTSA for cuff tear arthropathy or irreparable cuff tears with preoperative magnetic resonance imaging and pre- and postoperative radiographs at 1 year, and whose various functional outcomes including pain visual analogue scale (VAS), simple shoulder test, Constant score, American Shoulder and Elbow Surgeons score, and active range of motion were evaluated preoperatively and at the last follow-up (>12 months) were enrolled. The outcome parameter was set as a satisfaction scale. Various clinical and radiographic factors were analyzed, and their correlations with postoperative satisfaction were evaluated. RESULTS: All functional scores, VAS pain score, and active forward flexion showed significant improvement after surgery (all p<0.001). Twenty-nine patients were satisfied with the results and 14 were dissatisfied. The presence of pseudoparalysis (p=0.028) and worse preoperative function (all p<0.05) were related with higher satisfaction. Any radiologic parameters did not affect patients' postoperative satisfaction. CONCLUSIONS: All patients showed a good functional outcome after RTSA, however the patients' subjective postoperative satisfaction was affected by preoperative functional status (higher satisfaction in poor preoperative function), not by radiological findings.

OBJECTIVES: To evaluate the relation between diagnostic clinical parameters and the depth of trophoblastic invasion in tubal pregnancy and decide the most predictable parameter. Methods: Total 50 patients who were confirmed as tubal pregnancy pathologically, from Jan. to Dec. 1997, were included in this study. Menstrual missed periods was calculated by clinical history, volume of gestational mass was calculated as sphere, beta-hCG was titered with preoperative blood sample. All surgical specimens were examined pathologically and divided into two groups such as intraluminal and extraluminal, defined as intact tubal musculature and trophoblastic invasion beyond musculature, n=22 and n=28, respectively. Statistical analysis was performed among three parameters and between each parameter and the depth of trophoblastic invasion. Statistical analysis included were Student's t-test, Chi square, linear regression, and linear correlation analysis using SPSS statistical package and statistical significance was determined as p<0.05. RESULTS: There was a correlation between volume of gestational mass and beta-hCG(p<0.05), but not between beta-hCG and missed period or volume of gestational mass and missed period. beta-hCG level was 1843.7+/-1524.7 mIU/ml(Mean+/-SD) in intraluminal and 12144.3+/-10561.6 mIU/ml(Mean+/-SD) in extraluminal. There was a predictive correlation between beta-hCG and the depth of trophoblastic invasion(p<0.05), and cut off level 3,500 mIU/ml showed the highest sensitivity, specificity, positive predictive value, negative predictive value, 0.79, 0.86, 0.88, 0.76, respectively. Two parameters(volume of gestational mass and missed period) had no ability to predict whether intraluminal or extraluminal. CONCLUSION: We suggest that successful medical treatment of tubal pregnancy depend on lesional intactness of vasculature for drug delivery. In patient selection for medical treatment, it should be important to predict intraluminal type because of intact vasculature. Of clinical parameters, beta-hCG is single most predictive parameter, cut off level of 3,500 mIU/ml was the most reasonable level in this study.

Epidermolysis bullosa dystrophica is rare, chronic non-inflammtory mechanobullous disease of hereditary trait, which easily produces bullae by minor trauma or sponta neosly. A 1-day old male neonate presented wide spread vesicobullous minor, eruptions since birth. On examination, tense bullse were noted on the dorsa of the feet and right knei: area Which is usually serous but may be hemarrhagic tendeney. This was healed by the dropping of oxoline and wet betadine auze application along with the administration of vitamin E and phenytoin. We present a case of epidermolysis bullosa dystrophica that seems be a dominant type considering the presence of family history with histopathologic and electron microscopic findings.

Infantile acute hemorrhagic edema of the skin(IAHE) is a benign disease which affects infants between 4 months and 2 years of age and is characterized by palpable ecchymotic purpura and edema on the limb and face. We report a typical case of IAHE, which was presenting a cockade, annular, reticulated, and iris-like purpura and edema on the face and extremities in a 19-month-old male infant. We consider it to be a new disease category because its characteristics different markedly from HenochSchoenlein purpura in several clinical and histopathologic findings.
