BACKGROUND: Even though excellent impression materials are now available for making accurate replication for hard and soft tissue, the numerous dentists have faced lots of obstacles in making simultaneous impressions of multiple abutments. CASE DESCRIPTION: This article describes a modified method of tray fabrication using auto-polymerizing acrylic resin and impression technique for multiple prepared teeth in cases with limitations and difficulties in taking dental impressions. CLINICAL IMPLICATION: This segmental tray technique has several advantages, including higher impression quality, fewer impressions, and being more comfortable for the patient and less stressful for the clinician.

Echocardiographic examination was performed before, immediately after, 4-6 months after and 10-12 months after mitral valve replacement(MVR) surgery in 46 patients with mitral valve disease(8 patients with mitral regurgitation, 24 patients with mitral stenosis and 14 patients with mitral stenosufficiency) to evaluate the effects of mitral valve replacement on dimension of left atrium and left ventricle, volume of left ventricle, ejection fraction(EF) and fractional shortening(FS) of left ventricle. The results are as follows : 1) The endsystolic dimension(ESD), enddiastolic dimension(EDD), endsystolic volume(ESV) and enddiastolic volume(EDV) decreased significantly after operation in patients with mitral stenoinsufficiency(MSR), the ESD, EDD, ESV and EDV increased significantly after the operation, but returned to preoperative value 10-12 months after the operation. 2) The EF and FS of left ventrcle after MVR were significantly lower than preoperative value throughout the postoperative period in patients with MR. However in patients with MS or MSR, there were no significant postoperative changes in EF and FS, except transient depression in the patients with MS at the immediate postoperative period. 3) In all patients with mitral valve disease, the left atrial dimension and the ratio of domension of left atrium to the dimension of aorta decreased significantly after MVR. From above results, it is suggested that surgery should be considered seriously for the patients with MR before the ESD, EDD and ESV increase maekedly, even if the EF anf FS are in normal range and the symptoms are not severe, to prevent irreversible depression of myocardial function. It seems that serial echocardiographic examination is very helpful in this respect.

This study was conducted to evaluate the association of job characteristics and stress indicators, from May 1st to 10th, 1996. The study population was 210 workers (clerical workers, 67; engineers, 82; assembly line workers, 61) engaged in a television manufacturing company. A questionnaire method was used to collect the data regarding to job demand, job control, behavioral type, life style and psychiatric symptoms. Clinical examination was conducted to measure blood pressure, serum cholesterol, fasting blood sugar and HbA1c. Percentage of high subjective job strain group was significantly higher in clerical workers(9.0 %) than in engineers(4.9 %) and in assembly line workers(3.3 %) (p < 0.01). Mean values of fasting blood sugar and HbA1c were significantly different between types of occupation and were the highest in clerical workers (p < 0.05). Significant association was found between perceived job characteristics and psychiatric symptom score (p < 0.01). The more job demand and the less job control was, the higher psychiatric symptom score was reported. Diastolic blood pressure was significantly related to job control (p < 0.05). The more job control was, the higher blood pressure was reported. In multiple regression analysis, job demand, job control and age were significant variables explaining the psychiatric symptoms and R2 was 0.23. Perceived job characteristics and type of occupation were not significant in explaining diastolic blood pressure and cholesterol. Type of occupation, job demand, age and BMI were significant variables explaining lasting blood sugar and R2 was 0.25. Type of occupation was the only significant variable explaining HbA1c and R2 was 0.07. According to this result, occupational type and subjective job characteristics must be considered in study of job stress. As a result of multiple analysis, subjective job characterics are significantly related to psychiatric symptoms and type of occupation is significantly related to fasting blood sugar and HbA1c.

Congenital Abnormalities

We reviewed 7 cases of congenital mesoblastic nephroma (4 cases of classical mesoblastic nephroma (CMN) and 3 cases of atypical mesoblastic nephroma (AMN)) using immuno-histochemical and flow cytometric study. Results are as follows. 1) The mean tumor size was 5 (3 to 7cm)cm in CMN and 9 (7 to 10cm)cm in AMN. The AMN revealed hemorrhage and necrosis in two Of three cases. A case of AMN showed cystic change without hemorrhage and necrosis. Mitotic count ranged in 0~4/10HPF in CMN and 20-35/10HPF in AMN. 2) Immunohistochemistry for vimentin was all positive. Actin, desmin were weakly positive in CMN, but negative in AMN. The findings were consistent with myofibroblastic differentiation in CMN and AMN was considered to be the less differentiated form of CMN. 3) Flow cytometiic analysis showed diploidy in two of two CMNs and two of three AMNs. Only one AMN showed aneuploidy with DNA index of 1.41. %SG2M were 8.1 and 15.9 (mean 12.0) in CMN and 16.9, 32.9 and 19.3 (mean 22.9) in AMN, respectively. We concluded that AMN should be distinguished from CMN, clinicopathologically.

Leiomyomas are the most common benign tumors of the uterus, and although they can occur at any site in the genitourinary tract, they very rarely originate from the urinary bladder. We report a case in which a leiomyoma occurred at that site, deseribing the US, CT, and MRI findings.

Edwards syndrome is first introduced by Edwards and characterized by facial anomalies, multiple cardiovascular, gastrointestinal, urogenital, and skeletal malformations. It results from triplication of part or all of chromosome 18 in some or all of the patient's cells. It has an incidence of 1 in 4,500 live births or less and short life expectancy. Recently we experienced a case of 3-day-old female new born infant with this syndrome. Post mortem examination showed progeric face with prominent occiput, large flabby ears, microphthalmia, and micrognathia, bilateral clenched hands with flexion contraction of middle fingers, and bilateral rockerbottom feet. Internal examination revealed horseshoe kidney, esophageal atresia with tracheoesophageal fistula, two accessory spleens, and multiple cardiac anomalies. A trisomy 18 was confirmed by the cytogenetic study.

A study of the volume and linear measurements of the breast to determine new nipple positions for 142 subjects was undertaken. Volume determination was done by using the Grossman-Roudner device. The size and shape of the female breast may differ significantly, and such size and linear measurements have to be measured accurately prior to breast aesthetic surgery. Statistical analysis of these results are closely related to physical constitution(height, weight, chest circumference). There have been increasing changes in linear measurement and decreasing changes in breast volume during the last 10 years, The results were as follows: 1) the mean distance from the midclavicular point to the nipple was 19.5cm, the distance from the sternal notch to the nipple was 19.4cm, the distance between nipples was 18.6cm, and the areolar diameter was 3.3cm, 2) the regression equation for the midclavicular point to the nipple was 7.236+ 0.00077x height(cm)+ 0.233 x weight(kg), for the sternal notch to the nipple was 8.845-0.0039 x height(cm)+ 0.214x weight(kg), for the distance between nipples was 11.192 - 0.0033xheight(cm)+ 0.151x weight(kg), and for the areolar diameter was 4.031+0.02xheight(cm)-0.048 x weight(kg),3) the mean value of breast volume of the left side was 209.6cc, and that of the right side was 211.8cc, 4) the regression equation for the mean breast volume was -137.673 + 6.668 x weight(kg), which was equal to -528.414 + 9.115x chest circumference under the axilla(cm) and -468.420 + 8.298 x chest circumference across the nipple (cm). In conclusion, these data could be useful for numerous aspects of breast surgery, including augmentation mammoplasty, mastopexy, reduction mammoplasty, and correction of asymmetrical breasts as the standard for Korean females, if we know the body constituents (weight, chest circumference) before surgery.
