We report a 19-year-old man with hyperkeratosis of nipple and areola which is a part of an epidermal nevus. He did not have a history of endocrinopathy or synthetic steroid therapy. The lesion, a fingertip sized verrucous dark browncolored macule on left upper back, had spread into left-anterior chest wall and had involved nipple and areola to make them hyperkerstotic and verrueous. Histologic section from the on left areola showed hyperkeratosis, papillomatosis, acanthosis and increased pigmentation in the basal cell layer. Chernical peeling with 30% trichloroacetic showed favorable response.

BACKGROUNDS: The Rh antigens are important m clinical practice. The classification of Rh phenotype is usually based on the antigen detection done by conventional serologic method, but it has many limitation such as delicate grading of antigen expression. Recently, Flowcytometry has been introduced in immunohematology to detect and quantitate cell bound immunoglobulins to assess blood cell antigens and related antibodies. So, we tried these method to detect Rh(D) antigen and measure its density and evaluated the possibility of clinical usage. MATERIALS AND METHODS: We performed a flowcytometric analysis for the expression of D antigen in D-positive, negative and weak D group in indirect immune fluorescence assay by using polyclonal antibodies. We measured the intensity of immunofluorescence as a degree of antigen density and analysed the difference of mean channel fluorescence value(MCF) among these groups. RESULTS: Weak D groups had the lower fluorescence than D-positive group, while D-negative sample showed the same fluorecence as negative ntrol. The difference of fluorescence intensity of D antigen between that of C antigen were not observed and were statistically insignificant. CONCLUSION: Flowcytometry appear to be a good tool for antigen density measurement in immunohematologic areas and shows the possibility of application to other aspect.

BACKGROUDNS: In Korea, CPDA-1 solution is currently used for blood preservation and by this anticoagulant solution, RBCs can be preserved for up to 35 days at the refrigerate temperature. RBC additive solutions (AS-1, AS-3, AS-5, SAG-M, SAG-PM) are widely used in the other countries for longer preservation of RBCs (42 days). We studied the survival of transfused RBCs preserved in SAG-M additive solution. MATERIALS AND METHODS: 400 mL of whole blood were collected from 8 healthy volunteers, Plasma was removed by centrifugation separation method at 2,960g, 10 minute and replaced by 100 mL of SAG-M additive solution. Autologous transfusions were done in two groups on day 20 and 42 with Na51CrO4 (Dupont, USA) labelled RBCs. After 3, 10, 15, 20, 30 minutes and 1, 2, 24 hours, 20 days, the venous blood samples were collected from the volunteers, and their radioactivities were measured by the Gamma-counter (Cobra II, Germany), and 24 hour survival rate were calculated by Moroff's method. RESULTS: The mean 24 hour survival rate was 89.0% in 20 days preservation group and 71.8% in 42 days preservation group. The mean half life of transfused RBCs were 27.8 days (n=2)and 24.3 days (n=4) in 20 days and 42 days preservation group, respectively. No complications were observed during the study period. CONCLUSIONS: The RBCs preserved in SAG-M additive solution were near within allowable survival rates for transfusion.

We report a case in which routine chest roentgenograms of an 840 g infant led to the belief that the peripherally inserted central catheter (PICC) was appropriately positioned within the superior vena cava when, in actuality, it was within the azygous arch. Although many cases of pleural effusions have been reported to be caused by a central venous catheter, a right-sided hydrothorax caused by azygous vein rupture from the use of a PICC is an extremely rare complication. Sudden changes in the condition of a preterm infant with PICC should raise the suspicion of a catheter- related problem.

PURPOSE: It has been proposed that a decreased nephron number may be associated with the increased risk of glomerulosclerosis. In order to test the hypothesis that a reduced number and an increased volume of glomeruli may contribute to the pathogenesis of focal segmental glomerulosclerosis (FSGS), we compared the number and volume of glomeruli between 9 patients with FSGS and 8 with minimal change nephrotic syndrome (MCNS). METHODS: Mean glomerular volume was measured using the method of Weibel and Gomez. An estimate of glomerular number (index) was obtained by multiplying the cortical volume of a kidney by the fraction of renal cortex made up of glomeruli and dividing this by the mean glomerular volume for that kidney x 10(6). We determined kidney volume from ultrasonographic measurement. RESULTS: Patients with FSGS had significantly greater glomerular volume than patients with MCNS [2.02+/-0.36 (x10(6) micrometer3) vs. 1.57+/-0.27 (x10(6) micrometer3)] (p<0.025). However, there was no significant difference in the index of glomerular number (estimated glomerular number) between FSGS & MCNS patients (2.8+/-1.4 vs. 3.0+/-0.8). CONCLUSION: The glomerular volume was greater in FSGS patients than MCNS patients. But there was no significant difference in the index of glomerular number between patients with FSGS and MCNS.

A current hypothesis gaining prominence proposes that activation of the telomerase is necessarey for cells to become immortal, or be capable of proliferating indefinitely. The theory suggersts that that almost all cancer cells must attain immortality for progression to malingnant state and, hence, require activation of telomerase. To assess the role of telomerase in the development of mailignant transformation of the uterine cervical carcinoma, telomerase activeiy was measured by using a recently developed sensitive RPR-based telomerase assay(telomeric repeat amplification protocol; TRAP)in benign uterine condition and invasive uterine cervical carcinoma tissues revealed to be telomerase positive (14/16, 88%) which represents a characteristic 6 bp ladder pattern, while none of the 4 cervical tissues with the nonspecific pathologic findings or just chronic cervictis which were obtained by simple bysterenctomy under the diagnoses of benign myoma or uterine prolapse showed any telomerase actiovity. These findings suggest that this enzyme activity may play a key role in the establishment and progression of the uterine cervical carcinoma. This activity of telomerase may influence from the initial stage of tumorigenesis of uterine cervical carcinoma because poitive findings were noticed from the early stage (stage Ia1) to the advanced stage. The results of neoadjuvant chemotherpy which were revealed in final histopathologic specimens following radical hysterectomuy, pelvic and raraaortic lymph nodes dissection (suggestion by Rosen et al,) were one grade IV wiht telomerase poistive, 2 grade III with all positivie, 5grade II with 3 positive 2 negative. The two cases of pelvic lymph node metastasis belong to the group of grade II and their activeities of telomerase were 1 positive and 1negative. The situation of apoptosis induced by antineoplastic chemotherapy has not been related to that of telomerase activeity. Furthemore, the late recurrences has been noticed over 5years follow-up following neoadjuvant chemotherapy and radical surgery for the management of the high risk group of patients (not shown in this study) This measn that the nowday's regimen for induction tumoricidals may have been operating as dual effects (partial restoring and redamaging) to the cell cycle chekpoint. Therefore if telomerase inhibitor will be applied combined whit the induction chemotherapy, unexpected benefits mignt be obtained for the patient with the advanced uterine cervical carcinoma.

OBJECTIVES: The objective of this paper is to assess which wide type monitor configurations are preferred when physicians use an Electronic Medical Record (EMR) system in an outpatient clinic setting. METHODS: We selected three kinds of monitor configurations available for adoption at outpatient clinics with reference to monitor market trends. Fifteen attending physicians of the Seoul National University Bundang Hospital used each monitor configuration in their outpatient clinics. After completing the outpatient sessions, they selected the best monitor configuration for criteria described in five questionnaire items. We counted the number of votes and reviewed opinions of participants. RESULTS: The Wide Quad High Definition (WQHD) 27-inch single monitor configuration was most preferred for all questionnaire items. All participants answered that the WQHD 27-inch single monitor configuration was the best for desk space utilization. Eleven out of fifteen participants chose the WQHD 27-inch single monitor configuration as the most suitable monitor for outpatient practice. CONCLUSIONS: This study found that physicians preferred the WQHD 27-inch single monitor configuration in outpatient clinic settings. Healthcare organizations need to consider this finding when they purchase wide type monitors for EMR systems instead of the standard type monitor.
