Mutation of the p53 gene frequently results in overexpression of the p53 protein and loss of its tumor-suppressing properties. The overexpression of the p53 gene could be an indicator of rapid proliferation, poor differentiation, advanced stages, or poor prognosis. The prognostic value of the overexpression of the p53 gene in colorectal carcinoma is equivocal. The presence of DNA aneuploidy has been described as a powerful adverse prognostic indicator in relation to survival. To investigate the prognostic significance of p53 expression, and the relationship with DNA ploidy, 92 cases of colorectal carcinomas were analyzed. The overexpression of p53 gene product was present in 50(54.4%) of 92 cases. p53 expression only correlated with recurrence or metastasis during the follow-up periods (p=0.045). DNA aneuploidy was observed in 32(39.1%) of 82 cases. DNA ploidy was strongly associated with lymph node invasion(p=0.005), Dukes' stage(p=0.003), TNM classification (p=0.003), and recurrence or metastasis during the follow-up periods (p=0.045). The frequency of DNA aneuploidy was higher in the p53-positive colorectal carcinomas(58.3%) than in the p53-negative colorectal carcinomas (21.6%) (p=0.003). p53-positive colorectal carcinomas had a higher rate of cell proliferation than p53-negative cases(p<0.001). These results suggest that checking the p53 expression and DNA ploidy could be useful prognostic indicators of colorectal carcinoma.

The cutaneous metastaaes from carcinoma of breast produce four definite clinical types: inflammatory carcinoma, telangiectatic carcinoma, nodular carcinoma, and carcinoma en cuirasse. We present a case of 51-year-old woman who had purpuric, hard, sclerotic plaque with ulceration, crust and. several pea-sized hemorrhagic papulovesicular eruptions on the right chest wall for one year. Histopathological findings show metastatic ductal carcinoma but, the primary focus was not determined.

We observed clinical and microscopic features in 34 patients with dermatofibroma. Of these features, peculiar epidermal changes were observed in six (17.6%) cases. These were keratoacanthosis(1 case), acanthosis nigricans-like(2 cases), pseudoepitheliomatous hyperplasia.(1 case), hair follicle-like basal cell proliferation(1 case) and early basalioma-like(1 case) changes.

Seckel syndrome is a rare, autosomal recessive disorder of severe growth retardation and distinct craniofacial, orodental, and skeletal anomalies. We report hereby the first two Korean cases of typical Seckel syndrome who had characteristic symptoms of intrauterine growth retardation, small head, large eyes, sharp facial features (beaked nose, dysplastic ears and narrow face) with underdeveloped chin, dwarfism, severe mental retardation, and other malformation. We report two cases of Seckel syndrome with a brief review of related literatures.

Newborns with ileal atresia frequently present with abdominal distension, bilious vomiting, and failure to pass meconium. Diagnosis is usually established on plain x-ray of the abdomen by the findings of distended small bowel loops and air-fluid levels. In the period of October 1988 to February 1994, 8 patients with congenital ileal atresia were operated and the following results were obtained. 1. Eight patients were comprise of 4 males and 4 females, the ratio of male and female was 1 : 1. 2. Six patients(75%) had been admitted to our hospital during three days of life. 3. Congenital ileal atresia was in 8 cases : Type I in two(25%), Type II in two(25%), Type III a in three(37.5%), Type III b in one(12.5%). 4. There was one premature patient who was small for gestational age. 5. Overall, abdominal distension and bilious vomiting occurring in seven patients, were frequent presenting complaints. 6. Diagnosis was possible with clinical symptom and simple abdomen. 7. Operative treatment was undertaken as soon as the diagnosis was made. In seven cases a primary end-to-end anastomosis was performed after resection of dilated proximal loop. 8. A total of four associated congenital anomalies were found in one patient. 9. Postoperative complications occurred in three cases(37.5%).

A case of bilateral absence of vas deference with sterility is reported. By new 15O cases of congenital absence of the vas deference, rather a rare congenital anomaly, were reported.

Angiogenesis is essential for the growth of solid tumors. Microvessel counts, which represent a measure of tumor angiogenesis, have been correlated with the overall survival of patients with a variety of malignancies. However, the significance of angiogenesis in renal cell carcinoma remains controversial. To determine whether angiogenesis correlates with prognosis of patients with renal cell carcinoma, we counted the microvessels within the primary tumors and compared their numbers with patients' prognosis. Tumor specimens from 42 patients were investigated. Microvessels were stained with anti-CD34 and anti-factor VIII-related antigen monoclonal antibodies. Significant correlation between microvessel counts for two antibodies was observed (r=0.875, p<0.01), although microvessel counts for CD34 were approximately two times higher. Microvessel counts were higher in clear cell than in non-clear cell carcinoma (p<0.05). These results suggest that immunostaining with anti-CD34 antibody may provide a more sensitive and accurate measure of tumor angiogenesis. There was no correlation between microvessel counts and nuclear grade, or TNM stage. In univariate analyses, nuclear grade and TNM stage were significantly associated with patient survival (p<0.01). But further studies on tumor angiogenesis of renal cell carcinoma are needed before it can be adopted as a prognostic marker.

In the treatment of flexor tendon injury of the hand, re-rupture after primary tendon repair is one of complications which occurs occasionally and so impose burden on both the patient and the surgeon. Authors experienced twelve cases of re-rupture after primary flexor tendon repair of 274 patients from Mar. 1989 to Mar.1996. The incidence of re-rupture after primary flexor tendon repair was 4.4% in author's series. One case happened with slip down injury, and in six cases re-rupture occurred during physical therapy with snapping click sound. However in five cases, the patients conldnt recognize any related causes. In majority of cases, re-ruptures were identified between three and five weeks after primary repair by the surgeon and the patient, so it could be suggested that the attention should be paid for the high possiblity of re-rupture during this period. Operative findings were the resorption and friability of repaired end with insecure suture fixation in two cases, rupture of suture material in four cases and loosening of the knot in six cases. From this study, the authors suggest the importance of knot, and recommend to make more than four knots on suture tie with attention to the tie direction, and advise careful physical therapy according to each patients' different situation. In the treatment of re-rupture, end-to-end re-anastomosis was available in seven cases (59%). In five cases (41%), tendon graft was needed. The clinical result of the re-rupture cases was evaluated by the Stickland evaluation method, and it was satisfactory in 67% of the patients who had the complication of re-rupture.
