Carcinoembryonic antigen (CEA) in now the most widely used and the most useful marker for many cancers, including those of the colon, lung, pancreas, and breast. Also CEA is widely used for detection, staging, recurrence, and assessing the response to therapy in colorectal cancer. METHODS: From 1992 to 1998 the clinical value of the pre- and postoperative serum levels of CEA who underwent curative surgery at Department of General Surgery, College of Medicine, Dongguk University KyungJu Hospital, in 140 s patient with colorectal cancer with abnormal levels of CEA (>or=5 ng/ml) was investigated. RESULTS: The results are as follows: 1) The positive rate of preoperative CEA level was 47%, so preoperative CEA level measurement was not useful as screening test for colorectal cancer. 2) There was no significant association between abnormal CEA level and the location of tumor. 3) There was significant association between increased levels of preoperative serum CEA and lymph node metastases. 4) The incidence of preoperatively elevated CEA levels in Dukes stages A, B, C, and D was 0%, 27%, 63%, 71%, respectively. There was significant association between increased levels of the preoperative serum CEA and the progressive stages of colorectal cancers. 5) There was no significant association between abnormal CEA level and histologic differentiation of tumor. In addition, there was no significant association between abnormal CEA level and ploidy status of tumor. 6) The recurrence rate was 20% and 77% in patients with preoperative levels of CEA<5 ng/ml and >5 ng/ml, respectively. 7) The recurrence rate was 11% and 64% in patients with postoperative levels of CEA <5 ng/ml and >5 ng/ml, respectively. 8) Considering as normal CEA levels up to 5.0 ng/ml, sensitivity was found to be 77%, specificity, 80%, and predictive value of an elevated CEA concentration, 77%. CONCLUSIONS: In conclusion, it is suggested that measurement of preoperative and serial postoperative CEA is very useful in assessing the prognosis and in detecting recurrences in colorectal cancer.

Partial trisomy 1q syndrome is a rare chromosomal abnormality. We report on a male infant with 46,XY,der(11)t(1;11)(q41;p15.5) due to unbalanced segregation of the maternal reciprocal balanced translocation 46,XX,t(1;11)(q41;p15.5). The baby presented with a mild phenotype, characterized by a triangular face, almond-shaped eyes, low ears, short stature with relatively long legs, and mild psychomotor retardation. We utilized whole genomic array comparative genome hybridization (CGH) with 4,000 selected bacterial artificial chromosomes (BACs) to define the chromosomal breakpoints and to delineate the extent of the partial trisomy in more detail. To our knowledge, this is the first case of nearly pure "partial trisomy 1q41" defined by whole genomic array CGH.

PURPOSE: To evaluate the quantitative accuracy of three-dimensional (3D) images by means of comparing distance measurements on the 3D images with direct measurements of dry human skull according to slice thickness and scanning modes. MATERIALS AND METHODS: An observer directly measured the distance of 21 line items between 12 orthodontic landmarks on the skull surface using a digital vernier caliper and each was repeated five times. The dry human skull was scanned with a Helical CT with various slice thickness (3, 5, 7 mm) and acquisition modes (Conventional and Helical). The same observer measured corresponding distance of the same items on reconstructed 3D images with the internal program of V-works 4.0 TM (Cybermed Inc., Seoul, Korea). The quantitative accuracy of distance measurements were statistically evaluated with Wilcoxons' two-sample test. RESULTS: 11 line items in Conventional 3 mm, 8 in Helical 3 mm, 11 in Conventional 5 mm, 10 in Helical 5 mm, 5 in Conventional 7 mm and 9 in Helical 7 mm showed no statistically significant difference. Average difference between direct measurements and measurements on 3D CT images was within 2 mm in 19 line items of Conventional 3 mm, 20 of Helical 3 mm, 15 of Conventional 5 mm, 18 of Helical 5 mm, 11 of Conventional 7 mm and 16 of Helical 7 mm. CONCLUSION: Considering image quality and patient's exposure time, scanning protocol of Helical 5 mm is recommended for 3D image analysis of the skull in CT.

PURPOSE: Regulatory T (Treg) cells are key modulators in the immune system. Recent studies have shown that atopic dermatitis (AD) patients have higher numbers of Treg cells; however, little is known about the specific phenotype and function of Treg cells in AD. MATERIALS AND METHODS: To identify differentially expressed proteins in peripheral induced Treg cells in AD and naturally derived Treg cells in normal controls, CD4?CD25? Treg cells were isolated from thymus tissue of normal mice and the spleens of AD mice. Membrane proteins were extracted, and quantitative proteomics labeling with Tandem Mass Tags (TMT) was performed, followed by one-dimensional liquid chromatography/tandem mass spectrometry analysis. RESULTS: Using TMT labeling, we identified 510 proteins, including 63 membrane proteins and 16 plasma membrane proteins. CD47 was one of the upregulated proteins in Treg cells in AD spleens. Although CD47 was expressed in all CD4? and CD8? T cells, a significantly higher expression of CD47 was observed in the Treg cells of AD mice and AD patients than in those of normal mice and healthy controls. Furthermore, Treg cells from the spleen showed a significantly higher expression of CD47 than those from the thymus. CONCLUSION: We found that CD47 is highly expressed in the Treg cells of AD mice, particularly in the spleen. Based on our results, we propose that CD47(high) Treg cells are likely induced Treg cells and that upregulated CD47 in the Treg cells of AD patients may play a role in the increased population of Treg cells in AD.

PURPOSE: The purpose of this study was to make a comparison between minimally invasive plate osteosynthesis (MIPO) and conventional open reduction and plating (COP) to treat displaced clavicle shaft fractures. MATERIALS AND METHODS: We retrospectively reviewed patients with clavicle shaft fractures, who underwent surgery by using a locking plate between May 2011 and August 2016. The inclusion criteria were: 1) displaced ≥20 mm, 2) acute fracture of less than 2 weeks from injury, 3) skeletally mature patients, and 4) follow-up of at least 6 months. The demographic data and clinical outcomes, including operation time, fracture union rate, union time, shortening of clavicle, shoulder functional score (University of California at Los Angeles score), and complications, were evaluated. The clavicle length ratio was measured to evaluate shortening. We compared the clinical outcomes between two groups: the COP group that included 21 patients treated with COP (group 1) and the MIPO group that included 19 patients treated with MIPO (group 2). RESULTS: In all cases, union of fractures was successfully achieved. The mean union time was 14.9 weeks in group 1 and 14.2 weeks in group 2 (p=0.713). Both groups had good functional scores (34.0 vs. 33.7, p=0.658). Group 2 had shorter operation time and less bleeding. There were no secondary interventions or infections. The clavicle length ratio was similar between the two groups; and all patients in both groups showed no shortening (less than 3%). There were no implant failures in either group. CONCLUSION: The clinical and radiologic outcomes were satisfactory in both groups. We suggest that MIPO may be a safe and effective method for displaced clavicle shaft fractures.

Patient education is important for successful management of atopic dermatitis; however, due to limited time and resources, patient education remains insufficient. This study aimed to investigate the current state of education provided by Korean dermatologists, pediatric allergists, and allergists to patients with atopic dermatitis. A questionnaire survey consisting of items regarding educational programs for patients with atopic dermatitis was conducted via e-mail. In total, 153 participants responded to the questionnaires, and 26.8% indicated that they have had separate educational programs. The workforce involved in the educational program included nurses, residents or fellows, dieticians, pharmacists, and clinical psychologists. Most education protocols addressed the characteristics and natural course of atopic dermatitis and environmental management. Overall, 96.7% of the participants replied that an additional charge is needed for education; moreover, additional assistance from an academic society or association, in the form of medical staff, organized data, and advertisement, is required to develop and provide a well-structured educational program. A standardized education protocol will effectively provide appropriate education for patients with atopic dermatitis. Arrangement of education fees, covered by the National Health Insurance Service, will lead to the establishment of a structured educational program and participation of an additional medical workforce.

BACKGROUND: Systemic immunomodulatory treatment is actively recommended in the treatment for moderate to severe atopic dermatitis (AD) patients. However, consensus criteria for the classification of AD severity or treatment refractoriness have not been established yet. OBJECTIVE: To establish consensus criteria on the definition of severity classification and treatment refractoriness of AD to provide a basis for proper treatment strategy. METHODS: The Korean Atopic Dermatitis Association (KADA) comprised a task force team to establish a definition of moderate to severe AD. A draft of definition of moderate to severe AD was made on the basis of evidence. The recommendation was confirmed by KADA members through a web-based survey. RESULTS: KADA approved that AD with 16≤eczema area and severity index (EASI)<23 should be basically defined as moderate AD whereas AD with EASI score ≥23 should be considered as severe AD. They agreed that it would be reasonable to raise the severity level if patient's daytime or nighttime pruritus numerical rating scale is equal to or higher than 7 (≥7) or dermatology life quality index score exceeds 10. AD patients who do not reach EASI 50 after appropriate treatment for three months should be considered as a non-responder. Patients with recurrence (EASI ≥16) within three months after cessation of treatment should be considered as a recurrent AD. CONCLUSION: KADA built a consensus of definition of moderate and severe AD and treatment-refractoriness. These guidelines are expected to help physicians determine proper treatment options in need.

OBJECTIVES: The purpose of this study was to review an implementation of u-Severance information system with focus on electronic hospital records (EHR) and to suggest future improvements. METHODS: Clinical Data Repository (CDR) of u-Severance involved implementing electronic medical records (EMR) as the basis of EHR and the management of individual health records. EHR were implemented with service enhancements extending to the clinical decision support system (CDSS) and expanding the knowledge base for research with a repository for clinical data and medical care information. RESULTS: The EMR system of Yonsei University Health Systems (YUHS) consists of HP integrity superdome servers using MS SQL as a database management system and MS Windows as its operating system. CONCLUSIONS: YUHS is a high-performing medical institution with regards to efficient management and customer satisfaction; however, after 5 years of implementation of u-Severance system, several limitations with regards to expandability and security have been identified.
