1.Digital Reconstruction with Free Pulp Transfer from the Great Toe.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 1999;26(4):714-719
The authors report our experience of digital pulp reconstruction by free great toe pulp transfer. Twelve patients were treated with lateral great toe hemipulp. Twelve cases of digital pulp defect were reviewed, including 2 thumbs and 10 indices. There were 11 primary cases and 1 case of secondary reconstruction. We noted no necrosis and 5 patients suffered from cold intolerance. The flap sensibility, according to ASSH criteria, was excellent in 1 case, good in 10 cases, fair in 1 case and poor in no cases. The range of the stationary two-point discrimination test was between 4 and 15mm (mean S2-PD value; 7.2mm). The subjective evaluation found in 11 patients was satisfactory and dissatisfactory in 1. Performing this procedure during the acute phase may improve the management of trauma by reducing the time needed for cicatrisation and the length of disability. Furthermore, the principal advantages of this procedure are minimal donor site morbidity, as well as excellent functional and cosmetic gain.

2.Correlation of Clinical Stage and Presumptive Prognostic Factors in Renal Cell Carcinoma.
Korean Journal of Pathology 1999;33(11):1061-1066
Renal cell carcinoma is the most common primary cancer of the kidney. The tumor stage is a reliable prognostic marker in renal cell carcinoma which is significantly associated with patient survival. But assessment of other prognostic factors has produced varying and often conflicting results. We reevaluated the significance of varied prognostic parameters in 33 cases of renal cell carcinoma; clinical stage, cell type, histologic pattern, DNA ploidy, Ki-67 labeling index, and bcl-2 oncoprotein expression. We could not statistically prove that DNA ploidy and bcl-2 expression were related to any examined parameters. Cell type was not related to clinical stage nor nuclear grade but there was a significant correlation (p=0.002) between cell type and histologic pattern. Nuclear grade (p=0.007) and Ki-67 labeling index (p=0.036) were significantly related to clinical stage, suggesting their value as complementary prognostic markers for renal cell carcinoma.

4.Flow Cytometric DNA Content Analysis in Breast Cancer Comparison study of fresh and paraffin-embedded tissues.
Korean Journal of Pathology 1998;32(11):993-999
DNA content of 25 cases of breast carcinoma was analyzed by flow cytometry in both fresh and formalin-fixed, paraffin-embedded tissue. Aneuploidy in fresh tissue and paraffin-embedded tissues was 72% and 32%, respectively. There was a 52% agreement in analysis of DNA ploidy between fresh and paraffin-embedded tissues. Most of the discrepancies resulted from loss of aneuploid peaks on the histograms of paraffin-embedded tissue. Mean S-phase fraction was slightly higher in a paraffin-embedded tissue than that in the fresh tissue; 19.2 9.1% versus 16.1 8.8% and there was no significant correlation between the S-phase fractions. In statistical analysis, the histologic and nuclear grades were not correlated with ploidy or mean S-phase fraction. Therefore it is strongly recommended to use the fresh tissue in flow cytometric DNA content analysis of breast cancer.

To search the effective antisense oligonucleotide that inhibit the growth of Herpes simplex virus type 1 (HSV-1), six kinds of phosphorothioate oligodeoxynucleotides (S-ODNs) were synthesized and the antiviral activity was assessed by measuring cytopathic effect in Vero cells infected with HSV-1. Of the three dodecamer S-ODNs, cornplernentary to the translation initiation site of IE2 (AS2) and scrambled S-ODN (AS1) showed more significant antiherpetic activity than AS4 complementary to the IE4. Accordingly, the antiviral effect of dodecamer S-ODN was not specific. In contrast to the no inhibitory effect of sense strand S-ODN of ICP8 (AS6), two S-ODNs complementary to the translation initiation site of ICP8 (AS3) and that of IE1 (AS5) showed potent antiherpetic activity assessed in vitro HSV-1 virus yield assay. Antiherpetic effect of AS3 was decreased in proportion to the addition of AS6. The synthesis of viral protein ICPS and IE1 were inhibited in AS3 and AS5 treated HSV-1 infected Vero cells, respectively. These findings suggest that antiherpetic effect of AS3 is specifically mediated by targeting ICPS. S-ODNs had no effect on Vero cell viability. The data suggest that the 19-mer S-ODNs may be effective in antiviral chemotherapy.

The dual muscle flap (Latissimus dorsi+ Serratus anterior muscle) based on the thoraco-dorsal vascular system for limb reconstruction has been infrequently reported. We have used this flap as a free flap for limb reconstruction in four patients (3 cases in lower linb, 1 in upper limb). A Latissmusi dorsi muscle or musculocutaneous flap and Serratus anterior muscle flap were used and all cases healed satisfactorily. The indications for this flap are to resurface two separate defects simultaneously or to resurface very large defects. It has the advantage of requiring anastomosis of one vascular pedicle only. This flap is particularly suitable for resurfacing defects wider than their length, in relation to the long axis of the limb.

Mutation of p53 tumor suppressor gene is now recognized as the most frequent genetic alteration in human neoplasms. Although meningiomas are common intracranial tumors, little is known about the clinical significance of p53 abnormalities in meningiomas. We studied 31 cases of meningioma to investigate the significance of p53 protein expression in meningiomas and its relationships with histological and clinical parameters and proliferative activity. Classical and atypical meningiomas were 16 (51.6%) and 15 cases (43.4%), respectively. p53 protein expression was detected in 4 (25.0%) of 16 classical, and 12 (80.0%) of 15 atypical meningiomas. p53 protein expression was correlated with Ki-67 staining index, atypical type, high histologic score, sheet pattern of the neoplastic cells, vascular proliferation, and male patient (p<0.05). In conclusion, immunohistochemical evaluation of p53 protein and histologic score of meningiomas are useful in assessing the prognosis.

Adenoma of the nipple is a benign tumor of the lactiferous ducts of the nipple which frequently causes erosion of the surface. It can clinically mmic Paget's disease and histologically be misdiagnosed as a well-differentiated adenocarcinoma. A 20-year-old woman developed an erythematous oozing patch on the right nipple two years ago, which subsequently developed iiito verrucous surfaccd papules. A biopsy specimen of the lesion showed focal acanthosis of the epidermis. The tumor was composed of fairly well-circumscribed, glandlike structures within the nipple stroma. Ductlike struciures, papillary areas, solid nests of cells and cysts lined by squarnous epithelium, could be seen, Two cell types lining the ducts were recognized; inner columnar cells and peripherally located cuboidal cells. Although simple excision of the adenoma is the treatment of choice, our case was treated successfully by electrucoagulation.

BACKGROUND: It is important to evaluate the patient presenting with non-traumatic chest pain in emergency department, and it is also difficult to classify appropriately. The purpose of this study is to predict probability of acute myocardial infarction(AMI) and assess the group for low probability of AMI that is target for observation-unit of chest pain in emergency department. METHODS: A prospective, clinical study was performed from March 1998 to August 1998 at the department of emergency medicine, Ewha Womans University Mokdong hospital. We classified high-probability group and low-probability group of AMI according to Goldman's algorithm and then compared with the final diagnosis. RESULTS: The study included 218 patients. 84 patients(39%) was the high-probability group and 134 patients(61%) was the low-probability group of AMI. As compared with final diagnosis, AMI was 47 patients(56%) among the high-probability group and 1 patient(0.7%) among the low-probability group. We observed sensitivity of 98%, specificity of 78% in predicting AMI. CONCLUSION: The classification according to Goldman's algorithm may be useful predictor of AMI and improve triage for emergency department patient with chest pain. It is also helpful for management of observation-unit of chest pain in emergency department.
