Most of the breast cancer revealed mass and/or microcalcifications on mammography. We analyzed morphologic characteristics of the masses and microcalcifications on mammography which confirmed as breast cancer pathologically. Of all 54 cases, 4 patients (7%) showed microcalcification only, 27 patients (50%), mass only, and the other 23 patients (43%), both microcalcification and mass on the mammography. The margin of the breast mass were ill-defined in 37 cases, well-defined in 8 cases, and well-defined with surrounding infiltration in 5 cases. The morphologic characteristics of the microcalcification were punctate-linear-V shape in 11 patients, punctate-linear shape in 9 patients, and punctate shape in 7 patients.

BACKGROUND: Hepatitis A is an acute infectious disease of the liver caused by the hepatitis A virus (HAV). The purpose of this study was to investigate the HAV vaccination status and related factors among college students. METHODS: The study subjects were 503 students conveniently sampled from C university located in one district of Jeollanamdo. General characteristics and HAV vaccination related factors were collected by a self-reported questionnaire in October 2013. Chi-square tests and multiple logistic regression analyses were used to evaluate related factors with HAV vaccination. RESULTS: Of the 503 subjects without a history of HAV infection, 65 subjects (12.9%) reported that they were vaccinated. In multiple analyses, subjects who have had health screening (adjusted odds ratio, aOR=2.44 and 95% confidence interval, 95% CI=1.26-4.73) and those who were aware of HAV infection (aOR=6.00, 95% CI=1.81-19.91) or who perceived the benefits of HAV vaccine (aOR=2.05, 95% CI=1.07-3.93) were more likely to be vaccinated than those not involved in these factors. With regard to intention for HAV vaccine, 314 subjects (71.9%) reported that they have the intention to be vaccinated against HAV. In multiple analyses, higher grade level, high monthly allowance, awareness of HAV vaccine, perceived susceptibility of HAV, perceived seriousness of HAV and perceived benefits of HAV vaccine were significantly associated with the intention for HAV vaccination. CONCLUSIONS: The vaccination rate for HAV was found to be low in our sample of college students. To reduce health risks related with HAV, prevention efforts should consider these results.

PURPOSE: This study is to develop a hypothetical structural model of the quality of life of single aged women and to explain the compatibilities between the models and actual data. METHODS: Ten theoretical variables were used to evaluate of the quality of life of single aged women. 300 of single aged women were selected as the subjects. A hypothetical prediction model of quality of life was tested by the covariance structure analysis with PC-LISREL 8.12. RESULTS: Economy, religion activity, leisure activity, social support, self-esteem, depression and health prompting behavior were the significant variables which affected to the quality of life directly in the single aged women. But social support, self-esteem affected to them indirectly. Knowing perceived health status directly but it affected indirectly to the quality of life in single aged women. CONCLUSION: In this study, it was discovered that self-esteem was the most important factor to affect to the quality of life in single aged women and the next was the depression and health promoting behavior. As a result, it was discovered that age, economic status, self-esteem and depression were the significant factors to affect to the quality of life in single aged women.

PURPOSE: To evaluate the tear meniscus in aqueous tear-deficient dry eye patients using Fourier-domain optical coherence tomography (FD-OCT) and to investigate the clinical usefulness of tear meniscus values. METHODS: The present study included 79 aqueous tear-deficient dry eyes and 50 normal eyes. Tear meniscus height (TMH), tear meniscus depth (TMD), and tear meniscus area (TMA) were imaged using FD-OCT and measured with computer calipers. Schirmer's test, tear break-up time, and corneal fluorescein staining were also performed and the correlations between the tests were analyzed. Additionally, the diagnostic power of tear meniscus values was compared using area under the receiver operating characteristic curve (AUROC). RESULTS: Tear meniscus values were significantly decreased in the aqueous tear-deficient dry eye group (p < 0.05). TMH, TMD, and TMA were positively correlated with Schirmer's test and tear break-up time (p < 0.05), and TMH and TMD were negatively correlated with corneal fluorescein staining in the aqueous tear-deficient dry eye group (p < 0.05). The AUROCs of TMH, TMD, and TMA were 0.978, 0.788, and 0.957, respectively. CONCLUSIONS: Tear meniscus values measured using FD-OCT were significantly lower in aqueous tear-deficient dry eyes and were correlated with Schirmer's test, tear break-up time, and corneal fluorescein staining. Tear meniscus measurements obtained using FD-OCT can be useful clinical parameters for the diagnosis and treatment of aqueous tear-deficient dry eye.

The goal of the present study was to evaluate the effects of PNAM appliance and cheiloplasty on alveolar molding. Samples consisted of 16 unilateral cleft lip and palate infants (10 males and 6 female, mean age=37.0 days after birth, average alveolar cleft gap=10.46 mm), who were treated with PNAM appliances by one orthodontist and rotation- advancement cheiloplasty by one surgeon in Seoul National University Hospital. Average duration of alveolar molding treatment was 13.10 weeks and these patients were recalled at average 8.31 weeks after cheiloplasty. These patients' models were obtained at initial visit (T0, mean age : 37.0+/-27.89 days after birth), after successful alveolar molding (T1, mean age : 119.25+/-40.18 days after birth), and after cheilopasty (T2, mean age : 190.81+/-42.78 days after birth). Seven linear and five angular variables were measured using 1 : 1 photometry and soft ware program(V-ceph. Cybermed, Seoul, Korea). Paired t-test was performed to investigate statistical significance at p < 0.05 level. 1. The posterior parts of alveolar segments were the stable structures during alveolar molding treatment period and after cheiloplasty in infants. 2. The closure of cleft gap during alveolar molding was usually due to backward bending of the whole part of the greater segment. 3. Although forward growth of the greater segment was hindered by alveolar molding, it resumed after cheiloplasty. 4. Increase of anterior inter-segment angle after cheiloplasty was due to the molding effect of the lip scar pressuren

Radiofrequency ablation (RFA) is a new, minimally invasive modality that serves as an alternative to surgery in patients with thyroid tumors. The Task Force Committee of the Korean Society of Thyroid Radiology developed recommendations for the optimal use of RFA for thyroid tumors in 2012 and revised them in 2017. Herein, we review and summarize the 2017 thyroid RFA guideline and compare it with the 2012 thyroid RFA guideline.

9.History of Korean Society of Thyroid Radiology
International Journal of Thyroidology 2018;11(1):11-14
The Korean Society of Thyroid Radiology (KSThR) was founded as an affiliated subspecialty society of Korean Society of Radiology in 2010. The KSThR was originated from the thyroid radiology research committee which had started within the Korean Society of Neuroradiology in 2005. In the beginning, the research committee was organized to make a clinical guideline for ultrasonography (US) diagnosis and US-guided biopsy of thyroid nodules to cope with the rapidly increasing role of US imaging and the increasing burden of US-guided biopsy for thyroid nodules in the early 2000s. The KSThR proposed a subspecialty of thyroid radiology which is a medical subspecialty dealing with the imaging-based diagnosis and interventional treatment of thyroid disease. The KSThR has made an effort to make an advance in the research of thyroid imaging and intervention, which could provide scientific evidences for imaging-based management of nodular thyroid disease and thyroid cancers. The KSThR has published clinical guidelines of diagnostic imaging and interventional management of thyroid nodules, which included the US diagnosis and imaging-based management, fine-needle aspiration, core needle biopsy, and radiofrequency ablation therapy in thyroid nodules. The KSThR has a mission to play a leading role in the research and clinical practice of imaging-based management of thyroid disease, and the KSThR will make an advance in collaboration with Korean Thyroid Association.

This report describes an uncommon and fatal case of myocardial infarction due to coronary embolus arising from vegetation in the aortic valve with a background of infective endocarditis (IE). There are various causes of fatal IE. Myocardial infarction due to septic emboli is rare. We report a case of sudden death in a 69-year-old woman with hyperlipidemia and no known cardiac disease. She had severe general weakness and was hospitalized for colonoscopy. The patient unexpectedly presented with cardiac arrest and died. The autopsy showed total occlusion of the left anterior descending artery by an embolus, which originated from the septic vegetation of the aortic valve. Myocardial infarction from septic emboli associated with IE can be fatal and manifested as the first presentation. In autopsy practice of deceased patients with IE, careful examination of the coronary arteries is required.
