Nodular cystic fat necrosis, first described by Przyjemski and Schuster, is a peculiar form of encapsulated necrosis of subcutaneous fat characterized by totally or near-totally encapsulated necrosis of fatty tissue in which clusters of nonviable adipocytes are surrounded by condensed fibrous tissue. We report two cases of nodular cystic fat necrosis associated with history of trauma about the site of the lesion. Each lesion was a subcutaneous movable nodule on buttock (case 1) and shin (case 2) which has evolved over months. Both cases showed possible relation to multiple intramuscular injection or direct trauma injury. Pathologically, encapsulated nodule showed a characteristic feature of nodular cystic fat necrosis which composed of the ghosts of anucleated adipocytes showing fairly well-preserved outline.

Targetoid hemosiderotic nevus (THN) is a rare variant of melanocytic nevus, characterized by a sudden development of a targetoid ecchymotic halo around a pre-existing nevus. THN clinically raises concern for malignant transformation due to its abrupt change in color and size. THN should be distinguished from other diseases showing a peripheral halo, including targetoid hemosiderotic hemangioma, halo nevus, and Meyerson nevus. Dermoscopy can help clinicians to differentiate THN from these diseases. The typical dermoscopic features of THN are known to be divided into two distinctive areas: the central melanocytic area and the peripheral ecchymotic area. In our case, dermoscopy revealed a novel bull’s eye pattern composed of a central area with characteristic features of benign melanocytic nevus, an intermediated white circular ring, and a peripheral milky red area. When a sudden change occurs in a pre-existing nodule showing targetoid features, dermoscopy should be considered before conducting a biopsy or surgical intervention.

Capsule endoscope is self-contained videoendoscopy device that transmit images of the gastrointestinal tract to an external receiver. Capsule endoscopy has become a very important tool for diagnosing of small bowel disorders. Upcoming capsule endoscopy techniques for the investigation of esophageal, stomach, and colon may render it promising technique for these organs as well. This document is intended to provide the principles by which credentialing organizations may create practical guidelines for granting privileges to perform capsule endoscopy. KSGE recommends that the use of capsule endoscopy be limited to practitioners already competent and privileged to perform standard upper and lower endoscopy and who have extensive experience viewing gastrointestinal mucosa. KSGE recommends additional specific training in capsule endoscopy as well as review of the 20 procedures to verify competence. KSGE also admitted formal fellowship training having a familiarity with the hardware and software systems and interpretation of the at least 10 cases under the supervision of professor in capsule endoscopy during GI fellowship.

PURPOSE: Cyclin D1, which is known as a cell regulatory protein in G1-S phase, is overexpressed in 30-90% of breast cancers. Published data on the relationships between cyclin D1 and the established clinicopathologic factors of breast cancer have been controversial, so we investigated the clinical significance of cyclin D1 and its associations with established clinicopathologic factors in 103 primary breast-cancer patients. METHODS: Cyclin D1 overexpression was measured by using immunohistochemical assays, and the results were compared with clinicopathologic factors. RESULTS: Expression of cyclin D1 was detected in 60.2% (62/103) and cyclin D1 was significantly correlated with the estrogen receptor, the progesterone receptor, lymph-node metastasis, histologic grade, and nuclear grade. But there were no associations between cyclin D1 and tumor size, tumor stage, vascular invasion of tumor, DNA ploidy and S phase. CONCLUSION: We found that breast cancer with cyclin D1 overexpression was associated with predictive factors such as the estrogen receptor and the progesterone receptor. Thus, we suggest that aggressive treatment is needed in breast cancer with cyclin D1 overexpression. For cyclin D1 to become a more informative clinical prognostic factor, more prospective studies with large sample sizes are needed.

OBJECTIVES: The aim of this study was to evaluate the risk of recidivism in sex offenders according to the sociodemographic factors, IQ, diagnosis by using Static-99 and KSORAS. METHODS: A total of 48 sex offenders were enrolled. Among them, 44 offenders were rated by Static-99, 41 offenders were evaluated by KSORAS. All the information was collected by reviewing medical records and written records of prosecutors or police retrospectively. RESULTS: In Static-99 and KSORAS, young adults tend to commit more recidivism than late adults. Single offenders have high rates of recidivism than married offenders in Static-99. In KSORAS, mental retardation patients have a tendency to commit more recidivism than schizophrenia patients. CONCLUSION: We should not overlook that specific condition of sex offenders (young adults, single, mental retardation) can have more possibility of recidivism.

The cardiovascular manifestations of hyperthyroidism are sinus tachycardia, paroxysmal supraventricular tachycardia, atrial fibrillation, atrial flutter, atrioventricular block, bundle branch block, angina pectoris, heart failure, and cardiomyopathy. Though complete atrioventricular block is rare, it is important to recognize it in clinical practice because of the possibility of cardiac arrest. We experienced a 47-year-old female patient who had hyperthyroidism with complete atrioventricular block and developed cardiac arrest despite the initiation of an antithyroid drug. We could resuscitate successfully and inserted a temporary pacemaker, but eventually a permanent pacemaker was needed to prevent the recurrence of cardiac arrest. We report a rare case of complete atrioventricular block and cardiac arrest associated with hyperthyroidism with the review of references.

This study evaluated the methodological quality of CPGs using the Korean AGREE II scoring guide and a web-based appraisal system and was conducted by qualified appraisers. A total of 27 Korean CPGs were assessed under 6 domains and 23 items on the AGREE II instrument using the Korean scoring guide. The domain scores of the 27 guidelines were as following: the mean domain score was 82.7% (median 84.7%, ranging from 55.6% to 97.2%) for domain 1 (scope and purpose); 53.4% (median 56.9%, ranging from 11.1% to 95.8%) for domain 2 (stakeholder involvement); 63.0% (median 71.4%, ranging from 13.5% to 90.6%) for domain 3 (rigor of development); 88.9% (median 91.7%, ranging from 58.3% to 100.0%) for domain 4 (clarity of presentation); 30.1% (median 27.1%, ranging from 3.1% to 67.7%) for domain 5 (applicability); and 50.2% (median 58.3%, ranging from 0.0% to 93.8%) for domain 6 (editorial independence). Three domains including scope and purpose, rigor of development, and clarity of presentation were rated at more than 60% of the scaled domain score. Three domains including stakeholder involvement, applicability, and editorial independence were rated at less than 60% of the scaled domain score. Finally, of the 27 guidelines, 18 (66.7%) were rated at more than 60% of the scaled domain score for rigor of development and were categorized as high-quality guidelines.

PURPOSE: We purposed to determine the effects of urinary typsin inhibitor (ulinastatin) on the outcomes of severe sepsis and septic shock patients. METHODS: This is a prospective case control study of severe sepsis and septic shock patients who visited emergency department of university hospital from January 2005 to June 2008. For study group, 100,000 U of ulinastatin was initially infused and then additional infusions of ulinastatin were determined by the mean arterial pressure. We compared the predicted mortality and the actual in-hospital mortality between the ulinastatin group and the control group. We also compared the improvement of the SOFA score according to time between the groups. RESULTS: There were 43 patients in the ulinastatin group and 126 patients in the control group. The predicted mortality and the actual mortality of the ulinastatin group were 31.2% and 18.6%, respectively. The predicted and actual mortalities of the control group were 33.1% and 27.0%, respectively. The improvement of the SOFA score for the ulinastatin group was 6.8+/-3.9 and 5.0+/-4.5 at 0 and 24 hours (p<0.001), 6.5+/-3.7 and 3.9+/-4.3 at 0 and 48 hours (p<0.001) and, 6.3+/-3.6 and 3.0+/-4.1 at 0 and 72 hours (p<0.001). For the control group, the change of the SOFA score was 4.9+/-2.9 and 5.8+/-4.1 at 0 and 24 hours (p=0.003), 5.0+/-2.8 and 5.1+/-4.2 at 0 and 48 hours (p=0.760) and, 4.8+/-2.7 and 4.34.1 at 0 and 72 hours (p=0.105). CONCLUSION: The ulinastatin group showed significantly lower mortality than the predicted mortality and the ulinastatin group's SOFA score was improved in the early hospital days.
