We have experienced three cases of extrarnsmmary Pagets disease. The first case was a 77-year-old female who showed 8x10cm sized, erythematous plaque on the suprspubic area of one year's duration. The second case was a 60-year-old male who showed erythematous, oozing, crusted, well circumscribed patches on the right scrotum and the pubic area of 8 years' duration. Third case was a 79-year-old male who showed erythernstous to gray, eczemstoid plaques with marginal elevation on the right side of the scrotum, penile root and pubic area of 3 years duration. On histologic exarnination, the third case showed swest gland adenocarcinoma in the dermis.

Apoptosis is an intrinsic and fundamental biological process that plays a critical role in the normal development of multicellular organisms and in maintaining tissue homeostasis. Some of the well known regulators of apoptosis are cytokines of the tumor necrosis factor(TNF) ligand family, such as Fas ligand(Fas L) and TNF, which induce apoptosis by activation of their corresponding receptors, Fas and TNFR-1. Recently, a new member of the TNF family known as TRAIL (TNF-related apoptosis-inducing ligand) was identified and shown to induce p53-independent apoptosis in a variety of tumor cell lines but not in normal cells, Four human receptors for TRAIL were also recently identified and designated TRAIL-R1, -R2, -R3, and -R4. The aim of this study is to examine whether TRAIL and TRAIL receptots(-R1, -R2, -R3) are expressed in uterine cervical cancer and whether it is correlated with apoptosis, TRAIL and TRAIL receptors. The subjects were 20 patients who were diagnosed with cervical cancer. Western blotting was performed in 9 cases, immunohistochemical staining for TRAIL and TRAIL receptors(-R1, -R2, -R3) and TUNEL method for detection of apoptosis in 11 cases. There were proteins for TRAIL, TRAIL-R1, -R2, and -R3 in tissues from cervical cancer. All TRAIL receptors were expressed in both normal cervical epithelium and tumor cells, and TRAIL-Rl and -R2 were more strongly expressed in tumor cells than normal epithelium(p<0.05). Apoptosis correlated with expression of TRAIL-Rl and -R2(p<0.05). This study suggests that TRAIL induces apoptosis in cervical cancer through its receptors.

OBJECTIVE: User satisfaction of nursing information system and its user interface were measured in the S general hospital which new electronic medical record system had been introduced to. The new system had been developed based on nursing job's analysis. METHODS: 487 nurses who were working in the S hospital joined to survey through QUIS (Questionnaire for User Interface Satisfaction) about satisfaction of system they used. There were 4 categories-convenience, rapid response, content/configuration, accuracy of information. Those 4 categories were used analytical factors to know how the users were satisfied with its interface and function through the selected 13 system interfaces. RESULTS: With 9 scales of satisfaction score, we measured the satisfaction that the hardware provided. Terminology and system information got the highest score, and user friendly interface, easiness of learning, system performance in high score order. As like as above, we defined 5 scales of user interface satisfaction score. Content, configuration, information accuracy, convenience, rapid responses were identified as analytic categories. With interface satisfaction aspect, the pages which were reconfigured from physician order page to nurse interface got the highest score. And content and page configuration were acknowledged as the highest place. CONCLUSION: This study showed the nurses were satisfied with nursing information system. Also the trend of system development can be revealed.

BACKGREOUND: The pneumonectomy may depress the right ventricular (RV) function transiently. The thermodilution ejection/volumetric catheter is known to be most useful method assessing the changes in RV performance during pulmonary resection. The purpose of this study was to examine the RV function during and immediately after pneumonectomy using thermodilution methods. METHODS: 16 patients undergoing pneumonectomy were studied. After induction of anesthesia, a multilumen thermodilution catheter mounted with a rapid response thermister was inserted. Using computer system, RV ejection fraction (RVEF), cardiac output, and RV end-diastolic volume (RVEDV) were measured when the patient was in lateral position (control), after one lung ventilation (OLV) and the main pulmonary artery ligated, and at the completion of resection. Arterial blood gases were analyzed and pulmonary vascular resistance (PVR) was calculated. RESULTS: Systolic pulmonary blood pressure (SPAP)(28.3 +/- 6.2 mmHg) increased compared to the control (24.6 +/- 5.9) without a significant change of PVR. No statistically significant difference was found in either RVEF or RVEDV at each times. CONCLUSIONS: Our study demonstrate the pneumonectomy do not depress the RV function immediately and RVEF do not show any correlation with PVR or RVEDV.

OBJECTIVE: the enzymes cyclooxygenase(COX)-1 and -2 are necessary for the synthesis of prostaglandins. COX-2 is usually absent in normal cells and is upregulated and expressed as a product of the "immediate early" gene during inflammatory processes. In previous studies, the expression of COX-2 has been shown to be induced by prointlammatory cytockines, and suggestions have been made that overexpression of COX-2 supresses apoptosis and is directly related to tumor growth. We the authors have attempted to determine a relationship between the tumor invasion and metastasis of uterine cervical cancer and COX and apoptosis by comparing the protein expression of apoptosis and COX-I and COX-2 in tumor tissues confirmed with cytokeratin, and therefe determine the clinicopathologic risk factors. MATERIALS AND METHODS: The subjects were 18 patients who were FIGO stage IB uterine cervical cancer patients who underwent surgery at the Ajou University Medical Center. The 18 cases were comprised of 12 cases of squamous cell carcinoma, 3 cases each of adenocarcinoma and adenosquamous carcinoma. There were 9 cases with lymph node or prarametrial involvement and 13 cases with lymphvascular space involvement. All tissues obtained from the cases were subject to immunohistochemical staining for COX-1, -2 and TUNEL method for apoptosis detection, and the following results were obtained. RESULTS: Tumor tissues confirmed by cytokeratin wae separated into tumor surface, tumor stroma, and invasion site portions, and in which increased apoptosis was observed in the tumor surface and tumor stmma, but not in the invasion sites. COX-2 expression was observed in all tumor tissues, which was especially strong in the tumor invasion site. Therefore, it is suggested that COX-2 expression may supress cell apoptosis at the site of tumor invasion. When COX-2 expression was investigated when the cases were divided into groups with regard to the presence or absence of lymph node or parametrial involvement, there was statistically significant (Mann-Whitney U test) COX-2 expression seen microscopically in the tumor stroma (p-value=0.028) and tumor invasion site (p-value=0.040) compared to the tumor surface (p-value=0.499). In other words, in surgically treated stage IB cervical cancer patients, COX-2 was significantly expressed when lymph node or parametrial involvement was present. CONCLUSIONS: These results suggest that the expression of COX-2 in stage IB cervical cancer patients may downregulate apoptosic processes and thus enhances tumor invasion and metastasis.

To evaluate the coronary vasomotor tone in vasospasic angina, we compared the diameters of non-spastic segments of vasospastic group with those of control group. The internal diameters of each segment of three major coronary arteries were measured on the basal coronary angiogram, and nitroglycerin administration after provocation with ergonovine or acetylcholine. The vasospastic angina group consisted of 26 patients(20 males, 6 females, mean age of 54 years) and control group consisted of 25 patients (7 males, 18 females, mean age of 55 years). The basal coronary arterial diameters in vasospastic angina group were smaller than those in control group(p<0.05) except the distal segment of right coronary artery. The percent dilation ratio in vasospastic angina group was greater than that in control group(p<0.05). In vasospastic angina group there was no significant difference in the degree of constriction after provocation with ergonovine or acetylcholine between proximal and distal segment. These observations suggest that in vasospastic angina, basal coronary arterial tone is increased in the entire coronary arterial tree and the localized spasm may reflect local hyperrespon siveness.

Lipoblastoma are rare benign tumors arising from the fetal-embryonal fat that occur almost exclusively in children. About 70% of them arise in the limbs but several other sites have been reported. We have treated a 3-year-old boy who had a benign lipoblastoma in left posterior mediastinum and left supraclavicular area. CT scanning demonstrated a mass of principally fat attenuation which had a compressive effect on normal intrathoracic structures. The tumor was resected completely without complication from the left posterior mediastinum and left supraclavicular area. The tumor mass was yellowish in color and it was histopathologically confirmed to be a lipoblastoma.

BACKGROUND AND OBJECTIVES: Human epidermis is a continuously dividing tissue, in which keratinocytes gradually differentiate and mature while moving from basal cells to suprabasal cell layers. Epidermal homeostasis is maintained by a delicate balance between proliferation and terminal differentiation. Cholesteatoma is characterized by the presence of a squamous epithelium invading the middle ear, which is believed to have hyperproliferative properties. The aim of this study is to determine whether the hyperproliferative character of cholesteatoma is associated with differentiation of basal cell or suprabasal cell layers. MATERIALS AND METHODS: Using immunohistochemical techniques, we investigated the reaction pattern of monoclonal antibody to involucrin and filaggrin as differentiation markers in the cholesteatoma matrices which were harvested during surgery. For the control, the same immunohistochemical study was also done in deep meatal skin and retroauricular skin during the same surgery. RESULTS: The immunostaining intensity of filaggrin at suprabasal cell layers was higher in cholesteatoma than in retroauricular skin and deep meatal skin. The immunostaining intensity of involucrin at suprabasal cell layers was higher in cholesteatoma and deep meatal skin than in retroauricular skin. CONCLUSION: This result represents that the epidermal cells in cholesteatoma at suprabasal layers actively differentiate more than the epidermal cells in retroauricular skin. So this study suggests that hyperkeratinization in cholesteatoma might be due to altered differentiation of suprabasal keratinocytes. Furthermore, this study reveals that the deep meatal skin has unusual hyperproliferative behavior in contrast to the retroauricular skin.

Several studies have suggested that a positive lymphocyte cross-matching (XM) is associated with low graft survival rates and a high prevalence of acute rejection after adult living donor liver transplantations (ALDLTs) using a small-for-size graft. However, there is still no consensus on preoperative desensitization. We adopted the desensitization protocol from ABO-incompatible LDLT. We performed desensitization for the selected patients according to the degree of T lymphocyte cross-match titer, model for end-stage liver disease (MELD) score, and graft liver volume. We retrospectively evaluated 230 consecutive ALDLT recipients for 5 yr. Eleven recipients (4.8%) showed a positive XM. Among them, five patients with the high titer (> 1:16) by antihuman globulin-augmented method (T-AHG) and one with a low titer but a high MELD score of 36 were selected for desensitization: rituximab injection and plasmapheresis before the transplantation. There were no major side effects of desensitization. Four of the patients showed successful depletion of the T-AHG titer. There was no mortality and hyperacute rejection in lymphocyte XM-positive patients, showing no significant difference in survival outcome between two groups (P=1.000). In conclusion, this desensitization protocol for the selected recipients considering the degree of T lymphocyte cross-match titer, MELD score, and graft liver volume is feasible and safe.
