PURPOSE: The objective of augmentation mammoplasty includes reconstruction and cosmesis after breast surgery Increasing frequency of the procedure has been related with increased complications. Authors evaluated the value of breast MRI in the diagnosis of complications after augmentation mammoplasty. MATERIALS AND METHODS: Authors studied 42 breasts of 24 patients, who had undertaken augmentation mammoplasty. We evaluated findings of mammography, ultrasonography, and breast MRI in all patients. We used variable MRI sequences for better evaluation of implant status. The results were compared with the findings in surgical field. RESULTS: In all imaging studies, nodule or mass was indentifiable in the cases of interstitial paraffine injection(8 breasts), interstitial silicon injection(7 breasts), and herb medication(2 breasts). However, the differentitation between malignant and benign nodule was only possible at dynamic breast MRI. Mammogram was not helpful in the evaluation of extracapsular rupture in the cases of silastic bag insertion. In sonogram, identification of echogenic material was possible, although, false negative and false positive rate were high. MRI was able to visualize contour of entire implant and it was able to easily recognize low signal internal structure. CONCLUSION: MRI was the most accurate diagnostic tool in the evaluation of the character of the palpable mass after augmentation mammoplasty and early detection of breast implant rupture.

Extravasation of toxic chemotherapeutic 'agents cause severe skin ulceration and necrosis which often need secondary surgical intervention. Still, there were not established antidote agent in case of extravasation with mitomycin-c. Dimethyl sulfoxide is known as an effective chemical scavenger of toxic hydroxyl free radical and sodium thiosulfate also was demonstrated significant protector from mitomycin-c induced ulceration by a few experimental studies. Author investigated necrotic area of mitomycin-c injected site and compare to the effectiveness of topical treatment with dimethyl sulfoxide and intradermal injection of sodium thiosulfate according to starting times, forty five mice were divided into 3 groups. Control group(n=5) had no treatment after subcutaneous injection of mitomycin-c. Experimental group I and 11 were 20 mice treated dimethyl sulfoxide and sodium.

Infantile hemangioendothelioma of the liver is a common vascular tumor in infancy. The tumor is usually multinodular or diffuse and classified into two types. We present a case of infantile hemangioendothelioma of the liver, which predominantly consists of type 2. A 4-month-old female was admitted for an evaulation of an abdominal distension. A CT scan of the liver showed a multinodular mass. The right lobectomy was done. Grossly, the mass consisted of round nodules ranging from 2cm to 5cm in diameter. Microscopically, the tumor revealed proliferation of small vascular channels lined by endothelial cells. Bizarre cells and mitotic cells were frequently noted. Vesicular nuclei and multilayering of the endothelial cells were also noted.

Epstein-Barr virus (EBV) has been known to be associated with a wide variety of neoplastic conditions including nasopharyngeal carcinoma, Hodgkin's disease, and non-Hodgkin's lymphoma. Recent studies reveal the presence of EBV in certain subtypes of gastric carcinoma in which EBV appears to be pathogenetically related. To evaluate the relationship between EBV and gastric adenocarcinoma, we examined EBV DNA using direct in situ polymerase chain reaction, and expression of p53 protein and bcl-2 protein using immunohistochemical staining method on paraffin embedded tissues. The materials consisted of one hundred twenty-eight gastric adenocarcinomas and twenty benign peptic ulcers. EBV DNA was detected in 14 of 128 gastric adenocarcinomas (10.9%). p53 protein was positive in 10 of 14 EBV positive adenocarcinomas (71.4%) and in 61 of 114 EBV negative adenocarcinomas (53.5%). Bcl-2 protein was positive in 2 of 14 EBV positive adenocarcinomas (14.3%) and in 19 of 114 EBV negative adenocarcinomas (16.7%). The above results indicate that EBV is associated with gastric adenocarcinoma, and p53 protein may play a role in carcinogenesis of EBV in gastric adenocarcinoma.

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

In order to evaluate the genotoxic hazard among workers potentially exposed to low level petrochemical substances, the analyses of micronuclei (MN) and sister chromatid exchanges (SCEs) in lymphocytes were performed in 46 male workers (as exposed group) and 46 nonexposed subjects (as control group). Mean frequencies of MN and SCEs (respectively, 12.9/1000 cells and 6.5/cell) in exposed group were very significantly higher than those (10.2/1000 cells and 5.4/cell) in control group. And there were also significant differences in mean frequencies of MN and SCEs adjusted for age, employment duration, smoking, and drinking between two groups. Median frequencies of MN and SCEs in exposed group were very significantly higher than those in control group. Frequencies of SCEs were higher in smokers than in non-smoker. Frequencies of MN in smokers, however, were similiar to those of non-smoker. Interaction between exposure and smoking on MN and SCEs induction was not observed. The results suggest that there is genotoxic hazard in high risk group like workers handling carcinogens in petrochemical plants and the analyses of MN and SCEs are useful biomarkers for the exposure to hazard substances even at the level below the exposure limit.

The T cell responses to hepatitis B surface antigen (HBsAg) were analyzed in acute hepatitis patients, chronic active hepatitis (CAH) patients and asymptomatic carriers. Neither proliferative responses nor substantial cytokine production of peripheral blood mononuclear cells (PBMC) in response to HBsAg was detected. For further studies, HBsAg- reactive T cell lines were prepared from PBMC of the hepatitis patients and asymptomatic carriers. No proliferative response of the T cell lines was observed. Interestingly, however, T cell lines obtained from acute hepatitis patients were found to produce IFN-r, but not IL- 4, in response to HBsAg stimulation, whereas T cell lines obtained from CAH patients and carriers were not. Results of this study suggest that HBsAg-reactive T cells producing Thl type cytokines may play an important role in the viral clearance during acute infections, while defects in those T cells may be responsible for the viral persistency.

BACKGROUND: In women, the prevalence of depression is known to be more than twice as high as in men. Because many depressive women complain of their somatic symptoms instead of neurovegetative ones, many cases of depression have been misdiagnosed. Women also tend to use medicine more frequently than men do to manage depression. So we investigated the relationship between somatic symptoms and drug use in housewives for better management. METHODS: From 1st. March to 31st. March in 1996, the prepared questionnaires were presented to housewives living in the area of Kyung-ju city, who responded the questionnaires under direct interview. The questionnaire was composed of two parts. One part included demographic data, somatic complaints, drug use, places of drug purchase, current diseases that had been diagnosed by doctors. The other included Korean standard Beck Depression Inventory-questionnaire. The subjects were divided into two groups by BDI score(21 point), which was the cut-off point for depression in Korea. The relationships of somatic symptoms and drug use between the two groups were analyzed. RESULTS: There were 110 housewives who had depressive trends among 569 respondents. In general characteristics, there was significant difference between the two groups except the item of religion. In the items of somatic symptoms, there were more somatic symptoms in the group of high BDI score(>_21) except fatigue(P<0.01). More drug users were found in the group of high BDI score(>_21) (P<0.05). In the group of high BDI score(>_21), there was definite correlation between the items of somatic symptoms and drug use. There was no difference between the two groups in the item of drug purchase site. The most common site of drug purchase was the drug store in both groups. CONCLUSIONS: Depressive housewives complained of more somatic symptoms and more often used drugs as well.
