The p53 gene, one of the tumor suppressor genes, is believed to play an important role through mutation and overexpression in the progression of various human malignant tumors. To compare the p53 mutation status between the primary and metastatic lesions of breast cancers and to investigate the mutational pattern of p53, immunohistochemistry (IHC) and polymerase chain reaction and single strand conformational polymorphism (PCR-SSCP) were performed in 25 cases of breast cancers with paraffin embedded tissue. Mutant protein products or point mutation were detected through IHC or PCR-SSCP method. And flow cytometrical (FCM) analysis were performed in the same paraffin blocks to correlate the DNA ploidy and p53 mutation. The following results are summarized. 1. The detection of the p53 gene mutation and overexpression of the p53 protein were measured in 40% and 48%, respectively, in 25 primary tumors, either or both methods was detected in 64%. 2. A concordance rate of the p53 protein expression between the primary and metastatic lesions of 25 breast cancers was 100%, but the concordance rate of the p53 gene mutation was 72%. 3. The correlation between the p53 mutation and the DNA aneuploidy was not statistically significant (p=0.38) 4. A p53 mutation by IHC or PCR-SSCP was more frequently detected in grade III breast cancers than in grade I or II. 5. Among 5 to 9 exons of the p53 gene, exon 7 was the most frequent mutation spot in this study. 6. Additional mutation of the p53 gene was developed in the three metastatic lesions. With the above results it is suggested that the p53 protein overexpression by immunohistochemistry is not correlated with the p53 mutation by PCR-SSCP. The p53 mutation pattern between the primary and metastatic lesions are not idenitical and an additional point mutation can occur in the metastatic lesion. The DNA aneuploidy is more frequently detected in the cases with the p53 protein overexpression than in the p53 protein negative, but it is not statistically significant.

We report a case of hereditary trichilemmal cyst with proliferating trichilemmal tumor in a 64-year-oid man, who has generalized 157, variable sized firm cutaneous nodules for 40 years. The cystic nodules are chiefly located on the scalp and trunk which showed characteristic histopathologieal findings of trichilemmal cyst and proliferating trichilemmal tumors. His son also has multiple trichilemmal cysts and his mother seems to have had clinically similar lesions. The patient and his son were treated with surgical excision and therapeutic trial of oral isotretinoin for 2 months. Isotretionoin was ineffective in the patient, but the lesions of his son were decreased in size.

PURPOSE: This study was conducted to compare the PET and CT findings for patients with a pulmonary lymphangitic metastasis. MATERIALS AND METHODS: We retrospectively reviewed the PET and CT findings of seven patients diagnosed with a pulmonary lymphangitic metastasis between May 2005 and May 2007. RESULTS: All patients had interstitial thickening, as seen on a CT scan, while the PET scans showed abnormal findings in only three patients. In these three patients, one patient had interlobular septal thickening of more than 10, another patient had interlobular septal thickening of more than 5 but less than 10, and another patient had interlobular septal thickening of less than 5. All of the patients had bronchovascular bundle thickening. However, among the four patients that had normal FDG uptake, no patient had interlobular septal thickening of more than 10, two of the patients had interlobular septal thickening of more than 5 but less than 10, and the remaining patients had interlobular septal thickening of less than 5. Only two of the patients had bronchovascular bundle thickening. CONCLUSION: All patients with pulmonary lymphangitic metastasis have typical CT findings, but some of the patients had FDG uptake, as seen in the PET scans. Thus, CT is a more useful modality for diagnosis for pulmonary lymphangitic metastases.

The authors retrospectively reviewed the high resolution computed tomographic scans of 19 patients who had hematogenous or lymphangitic metastatic lung lesions. In all patients, the histologic diagnosis for primary cancers and the radiographic manifestations of pulmonary metastasis were established. Certain characteristic findings of metastatic lung tumors on HRCT scans were evident: uneven thickening of bronchovascular bundles, multiple small nodules, thickening of interlobular septum, and the presence of polygonal lines. The nodules are more predominent in hematogenous metastasis. The prevalent site of nodules is cortical portion of lung.

Repeat cesarean section is one of the leading causes to make increasing a rate of cesarean section. Trial of labor TOL after cesarean section is attempt to reduce the rate of repeat cesarean section. Trial of labor has been well established as a safe alternative in carefully selected women with transverse scars in the lower uterine segment. This study was based on 104 cases of delivery with prior cesarean birth at the Chonbuk National University Hospital from January, 1991 to June, 1997. The results were as follows: 1) Among 1400 cases with previous cesarean delivery, trial of labor was done in 104 cases (7.4%). Among 104 cases, vaginal birth was successfully completed in 96 cases (92.3%). 2) Among 28 cases with PGE2, vaginal tablet, vaginal delivery was done in 23 cases (82.1%). 3) Among 22 cases with more than 4 of Bishop score, vaginal delivery was done in 21 cases (95.5%), and among 6 cases with less than 3 of Bishop score, vaginal delivery was done only 2 cases (33.3%). 4) There was no matemal death or uterine rupture in the cases of trial of labor, But in 2 cases, uterine dehiscence was observed in 4 cases and postpartal bleeding (more than 400ml) was developed. 5) In the cases of cesarean section, mean of hospital day was 7 days and medical fee was about 400,000 won. In the cases of vaginal birth after cesarean section, mean of hospital day was 2.6 days and medical fee was about 100,000 won. In condusion, vaginal birth after cesarean section is safe and effective alternative to elective repeat cesarean section and also the use of PGE, vaginal tablet is so effective to increase success rate of vaginal delivery. After all, positive these trials might decrease cesarean rate and increase maternal health and quality of medical care.

Either increased cellular proliferation or decreased death might result in an expansion of their numbers in the oncogenic process. Cellular apoptosis represents an autonomous suicide pathway that helps to restrict the cell number. However bcl-2 and mutant p53 inhibit programmed cell death. To determine whether the bcl-2 gene is activated during colorectal tumorigenesis and whether it has any relationship with p53 and apoptosis, we studied the expression of bcl-2 and p53 in the normal colonic mucosa, in the adenomatous polyps and in the adenocarcinomas using the immunohistochemical method. Also we evaluated the status of apoptosis using the in situ end labeling method. The bcl-2 immunoreactivity was restricted to the basal epithelial cells of all normal colonic mucosa and they were expressed in all adenomas and 86% of adenocarcinomas, especially in the superficial lesion of some tumors. Mutations of p53 were not found in the normal colonic mucosa, but they were present in dysplastic cells of adenomas (52%) and in cancer cells of the adenocarcinomas (47%). Apoptosis was confined to the tips of the normal colonic mucosa. It was more easily detected in the p53-positive adenomas than in the p53-negative adenomas (p=0.010). In the adenocarcinomas, the findings of apoptotic process are not related with p53 mutation (p=0.3) and bcl-2 expression (p=0.187). p53 and bcl-2 are probably one step of several apoptotic processes in the adenocarcinomas.

Studies on epidemiological aspects of contact dermatitis have been published in recent years since the introduction of standardized method of patch test.However, most previous epidemiologic reports studied patients with allergic contact dermatitis in hospitals with patcb testing. Such data are not directly applicable to the population at large. Very recentiy there are a few reports ahout rates of exposure and patch test reactivity to certain antigens in a general population. which is difficult to be applicable in a developing country at present. With regard to this, we have tried to analyze the contact dermatitis questionaire containing various items of common causative agents producting contact dermatitis (for example, metals, cosmetics, plants, medicaments and rubber etc.) for the detection of past contact dermatitis histories in a total new dermatologic outpatients. A11 2258 dermatologic outpatients entered this study including 303 contact dermatitis patients (allergic contact dermatitis, primary irritant dermatitis and housewife eczema). We also analyzed the patch test results of 107 patients with suggesting contact dermatitis who visited our hospital at the same period of collecting questionaires. The study results were as follows. 1. Positive rate of each item of the questionaire (No. of said Yes/ No. of responders) was metals, 10.4% cosmetics, 31.8%, plants, 18.2%; medicaments, 12.4%; rubber, 5.8%; and others, 11.7%. 2. The most common all regens of the patch test positive reactions were nickel sulfate (9.3%), fragrance mix(9.3%), formaldehyde(6.5%), potassium dichromate (5.6%), neomycin sulfate (5.6%), balsam of Peru (4.7%), cobalt chloride(3.7%), wood tar(3.7%) and paraphenylene diamine (2.8%) in order of frequency. And the patch test positive rate of commercial cosmetic products was 10.3%. In conclusion, cosmetics, medicaments, metals, plants and rarely rubber are found the most common etiologic agents of contact dermatitis in this study. The reasons and back-ground of the results were also discussed in various aspects.
