OBJECTIVE: Quantitative analysis of both apoptosis and proliferation should provide important insight into tumor biology. The aim of this study is to clarify the significance of apoptosis in the progression of uterine cervical neoplasia, including cervical intraepithelial neoplasia, and microinvasive and invasive squamous cell carcinoma categories. in relation to cell proliferation. METHODS:: Forty five cases of cervical intraepithelial neopasia. 10 of microinvasive carcinoma, and 10 of invasive squamous cell carcinoma were examined using formalin fixed and paraffin embedded samples. The TdT mediated dUTP-biotin nick end labelling(TUNEL) method for apoptotic cells, and Ki-67 and Topo-II immunojhistochemistry for proliferating activity were performed. RESULTS: Apoptotic and proliferative indices, calculated by counting positive nuclei among 1,000 nuclei of cancer cells, should significant positive correlation with histological malignancy grading in CIN and tumor cell invasion into stroma, and showed also significant positive correlation between them. CONCLUSION: These findings suggest that apoptosis in cervical neoplasia may be closely related to tumor cell differentiation and progression.

Gram-negative toeweb infections have clinical manifest,ations of variable severity. In its mildest form, the affected tissue is damp, softened, boggy and white. But. more severe form may progress to marked denudation of second, third and fourth toewebs with a profuse serous or purulent discharge, and its treatment is difficult. We described a 39-year-old man who had ulcerated arid oozing patches on several toewebs. Pseudomonas aeruginosa was detected in bacterial cultures. We successfullg treated with split-thickness skin graft, and enoxacin on first, visit and enoxacin with gentamicin ointment, for 2 weeks on second visit.

Blunt tracheobronchial injuries are rare, and usually lethal without aggressive and appropriate management. Recently, the incidence of tracheobronchial injuries has been increased with the increase of traffic accident and mechanization. We report a case of complete tracheal transection combined with a longitudinal rupture of the membranous portion of the trachea extending to the right main bronchus following blunt chest trauma, and review the anesthetic management.

Familial or hereditary breast cancer has genetic heterogeneity and is transmitted vertically in an autosomal dominant fashion. About 5 to 10% of breast cancers are caused by the inheritance of mutations in dominant susceptibility genes. We retrospectively reviewed 50 breast cancer patients from 44 families. These patients had treated their breast cancer at the Department of Surgery, Yonsei University College of Medicine, from 1981 to 1996. There were no statistically significant differences between the familial breast cancers and the sporadic breast cancers in such clinicopathologic characteristics as major complaint, tumor location, tumor size, metastasis to axillary lymph nodes, stage distribution, histology distribution and hormone receptor status. For familial camcers, the mean survival was 125 months, the overal 5-year survival rate was 85%, and the overall 5-year disease-free survival rate was 70%.

Axillary breast is one of the varieties of polymastia which is characterized by the presence of more than 2 breasts. It may cause symptoms during pregnancy, lactation, or in the premenopausal period. Unless there are obvious symptoms of lactation or the assistance of further imaging studies such as mammography and breast ultrasound, the diagnosis is often confused with subcutaneous lipoma. The incidence of axillary breast cancer is low but it should be investigated and treated properly in view of another breast cancer in the embryonic milk-line. In this paper we reviewed 4 cases of axillary breast cancer and documented some articles regarding aberrant breast and carcinoma arising from it. It is suggested that subcutaneous nodules of uncertain origin around the periphery of the breast should be viewed with suspicion and treated properly.

"To evaluate whether different qualifications of a cytologic diagnosis of atypical squamous cells of undetermined significance (ASCUS) predict a greater or lesser likelihood of tissue diagnosis of uterine cervix, we compared different cytologic qualifications of ASCUS with the tissue diagnosis. One hundred twenty-two con- secutive Papanicolaou smears showing ASCUS in women who had undergone cervical biopsy within nearest 30 days were collected. The 122 smears were qualified as ""favor reactive (25%), favor low grade squamous intraepithelial lesion (LSIL) (24%), favor squamous intraepithelial lesion (SIL) (16%), favor high grade squa- mous intraepithelial lesion (HSIL) (16%), and not otherwise specified (19%). Squamous intraepithelial or invasive lesion was pathologically confirmed by cervical biopsy in 13% of the favor reactive, 27% in favor LSIL, 70% in ""favor SIL, 75% in favor HSIL, and 35% in not otherwise specified smears. There were significant associations between the favor reactive smear and the benign biopsy finding and between the favor SIL smear and the biopsy showing a squamous intraepithelial or more severe lesion. Nevertheless, rnost of favor LSIL smears exhibit reactive process in tissue biopsy. Conclusively, qualified ASCUS stratifies women into different risk groups for SIL. The cytopathologist should make the cytologic diagnosis of ASCUS, favor LSIL circumspectly."
