Uterine didelphys with unilateral hematometra, hemicolpos, and ipsilateral renal agenesis is a rare m01lerian duct malformation. Uterine didelphys with an obstructed hemivagina is frequently associated with renal agenesis, mostly ipsilateral to the blind vaginal pouch. Accurate early diagnosis and septal resection elevate pregnancy rate and birth rate but it is difficult to find these malfomations until the complication associated with pregnancy was developed. We report a case of successful gestational outcome in the presence of preterm labor due to hematometrocolpora caused by uterine didelphys with unilateral imperforated vagina and ipsilateral renal agenesis with brief review of the literatures.

There have been several reports that total knee arthroplasty(TKA) was most likely to survive successfully if the coronal tibiofemoral angle was close to 7 degree of valgus, the accepted normal. In order to know whether the postoperative coronal tibiofemoral angle influences the result of total knee arthroplasty, we examined the 152 TKA cases in 106 patients which had been performed at Department of Orthopaedic Surgery, Seoul National University Hospital from Jan. 1987 to Dec. 1991. In our series the average follow-up period was 31 months(range, 13 months to 75 months). Coronal tibiofemoral angles of all cases were checked on weight bearing anteroposterior plain X-rays and were divided into three groups(less than valgus 2° ; valgus 3° to 7° ; greater than valgus 8°). All cases were analyzed on the knee score of Hospital for Special Surgery and the American Knee Society total knee arthroplasty roentgenographic evaluation and scoring system and the cases with radiolucent lines wider than 2mm were checked. Three groups were analyzed comparatively with statistical means(Wilcoxon signed rank test, X² test). There were no significant differences in the clinical results of total knee arthroplasty according to the postoperative coronal tibiofemoral angle. Lateral subluxation of the patella occurred more frequently when the postoperative coronal tibiofemoral angle was above valgus 8°. In the tibial components of group lesser than valgus 2°, the frequency of radiolucent lines wider than 2mm was higher than those of other groups, but its significance should be examined through long term follow-up.

Although long-term studies of total knee arthroplasty(TKA) have confirmed reliable relief of pain and maintenance of function, survivorship at nine to ten years has been inconsistent with late component loosening being the most frequent mode of failure. Tibial component failure has been more frequent than failure of the femoral or patellar component in most TKA series. Encouraged by the early results of porous-ingrowh femoral and patellar components, and aware of retrieval studies showing poor bone ingrowth into tibial components, the “hybrid” method of fixation with an uncemented femoral component and a cemented tibial component, has been introduced and incorporated the potential advantages of both traditional fixation techniques. Between January 1987 and December 1991, forty-five “hybrid” TKAs(group I) were performed in degenerative arthritis and evaluated retrospectively in comparison with the results of nineteen noncemented porous-coated TKAs(group II) in degenerative arthritis. The average follow-up period was 31 months(range, 14 to 60 months) in group I and 26 months(range, 13 to 63 months) in group II. Using the knee rating scale of the Hospital for Special Surgery and the American Knee Society Roentgenographic Evaluation and Scoring System, clinical and radiological comparative study between two groups was performed. Pain scores, range of motion and HSS knee scores improved in both groups, but there was no significant difference between group I and group II(p>0.05). In both groups, the scores of radiolucent lines were significantly higher in zone 1 and 4 of A-P roentgenograph of the tibial component than in other zones(p < 0.05). The tibiofemoral angle was corrected from varus 2.7° to valgus 5.8° in group I and from varus 3.4° to valgus 4.6° in group II. There was no significant differences in component position and scores of radiolucnet lines between group I and group II. In conclusion, there were no significant differences in clinical and radiological results between the “hybrid” and the cementless groups. Results of this study suggest that both the hybrid fixation and the comentless techniques can reliably provide satisfactory clinical and radiological results in properly selected degenerative arthritis patients. But the final outcomes of this study need further evaluation through long term follow-up.

p53 is a tumor suppressor gene product identified in a wide range of tumor including colorectal carcinoma. Genetic alterations in the p53 tumor suppressor gene are common in human colorectal carcinoma. bcl-2 is a protooncogene that inhibits apoptosis. The products of mutant p53 gene and bcl-2 have been associated with prognosis in several malignancies including colorectal carcinomas. This study was undertaken to evaluate values of p53 and bcl-2 oncoproteins as prognostic factors relative to clinicopathological factors and correlation of their expression. Analyses were made on achieval pathologic tissues of 80 patients with colorectal carcinomas including 34 patients able to follow-up over 5 years. The oncoproteins were localized using commercially available monoclonal antibodies:DO-7 for p53, clone124 for bcl-2. Expression of bcl-2 was cytoplasmic, whereas nuclear p53 expression was localized in carcinoma cells. The patients were 17 to 83 years of age. The expression of p53 and bcl-2 was determined respectively in 30 (37.5%) and 21 (26.3%)cases. The expression of p53 nuclear expression was not correlated with tumor location, size, histologic grade, Duke's classification, regional lymph node metastasis and tumor recurrence. The cytoplasmic expression of bcl-2 was not correlated with tumor location, size, histologic grade, Duke's classification, regional lymph node metastasis and recurrence. Univariate analysis showed that patients with p53 nuclear expression were not associated with poorer overall survival than patients with p53 negative, and also showed in patients with bcl-2 expression. The expression of p53 did not affect to that of bcl-2. We concluded that the p53 nuclear and bcl-2 cytoplasmic expression were not independent prognostic factors in colorectal carcinomas. Evidence of reciprocity of bcl-2 and p53 expression was not found.

Results of 170 total knee arthroplasties(TKAs) performed from 1986 to 1995, followed up for at least one year, were reviewed. Lateral retinacular release was performed in 76 knees(45%) and not performed in 94 knees(55%). We compared the results of TKAs combined with lateral retinacular release with those without lateral retinacular release. The clinical results of TKAs were evaluated by the Knee Scoring System of Hospital for Special Surgery(HSS). The average follow-up period was 34 months. The clinical results assessed by HSS score, pain score and range of motion improved postoperatively in both groups, but there was no significant difference between the two groups. There were 8(4.7%) with patellar subluxations in 170 TKAs, one(1.3%) in the group with lateral retinacular release and 7(7.5%) in the group without lateral retinacular release(t-test; p<0.05). Analysis of lateral tilt of patella on roentgenographs also showed a significant difference between the two groups. 7 knees(9.2%) with lateral tilt were observed in the group with lateral retinacular release and 22 knees(23.4%) with lateral tilt in the group without lateral retinacular release(t-test; p<0.05). There was no osteonecrosis or fracture of patella in either group. In summary, lateral retinacular release might improve the patellar tracking and lower the incidence of patellar subluxation and lateral tilt of patella. Lateral retinacular release alone did not seem to cause patellar osteonecrosis and subsequent patellar fracture which were detectable in plain roentgenographs. So, we suggest that lateral retinacular release can be performed without great risk of potential patellar complications in TKAs requiring lateral retinacular release for proper patellar tracking.

This study was to find out whether the rendering screen difference affect to measuring distance in a CAD program according to three types of CAD programs. Materials and methods: The model presented in ISO 12836 for dental scanner evaluation was reduced by 70%. This model was repeatedly scanned 15times using Trios II (3Shape, Denmark). Using the output STL file, 3Shape CAD, inLab 15, and ExoCAD programs were used to measure the horizontal distance (H) and vertical distance (V) between adjacent point angle, and for each experiment, three groups were set according to the CAD program type. Statistical analysis was performed using One-way ANOVA test and post hoc was performed using Dunnett T3 test. Results: In the horizontal and vertical distance measurement, there was no difference in the average of the measured values between the three groups according to the CAD program (P>.05). Conclusion: There were no effect of the difference in the rendering screen in the horizontal and vertical linear distance measurements of the inlay model on the dental CAD program.

The expectoration of blood is always a fearful experience for the patient and a matter of grave concern to the attending physician, because it may be the warning sign of serious diseases. When such bleeding occurs, the possibility of its being due to pulmonary tuberculosis, bronchiectasis or carcinoma of the lung is promptly suggested. Nowadays, with the advance of modern diagnostic studies, differential diagnosis has become possible for the hemoptysis patients to have appropriate treatment. This evaluation is based on the review of 75 cases of patients whom we performed emergency open thoracotomies for 6 years from March 1992 to February 1997 in the Department of Thoracic and Cardiovascular Surgery, Seoul Adventist Hospital. The mean age of the patients was 36.6 years old with a range from 19 to 68, and most prevalent age group was thirties. The most common underlying lung disease causing hemoptysis was tuberculosis(44%). Most accurate diagnostic study was bronchoscopy during hemoptysis(95%) and right middle and lower lobe(17.3%) was the most common site of lesion. Lobectomy(50%) was the most frequent operative method and recurrent hemoptysis(31.6%) was the most common postoperative complication. But most of the patients(82.6%) were completely recovered by surgical treatment. Now we concluded that the proper management of hemoptysis was completed by surgical approach with definite diagnosis and supportive medication.
