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 splenic cystic lymphangioma is a very rare benign condition, and is classified as one of the cystic proliferations of the spleen. They are considered to result from developmental malformation of the lymphatic system and can be divided roughly into two types according to the extent of the disease: the isolated type, where only the spleen is involved, and the widespread type, where splenic involvement is an expression of multiple organ involvement. Thery are usually seen in children and often found incidentally. Herein, a case of cystic lymphangioma of the spleen in an elderly woman is presented, with emphasis on the rarity of cases in old age and on the problems of differential diagnosis in relation to other cystic proliferations of the spleen.

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.

Langerhans cell histiocytosis is a rare disorder with abnormal proliferation of histiocytes. Besides the infiltration of a variety of organs, patients with Langerhans cell histiocytosis can develop sclerosing cholangitis, with bile duct involvement, progressive fibrosis, and cirrhosis. We report a case of Langerhans cell histiocytosis with sclerosing cholangitis. Endoscopic retrograde cholangiopancreatography revealed multiple strictures and dilatations of left intrahepatic and extrahepatic bile duct. Endoscopic biopsy of common bile duct showed diffuse infiltration of histiocytes and eosinophiles in lamina propria. Immunohistochemical stain showed positive reactions for S-100 and CD1a and a negative reaction for cytokeratin in infiltrating histiocytes.
