Pericardial defect is a rare congenital cardiac disorder. Most patients were asymptomatic but some patients with partial pericardial defect occasionally complain acute symptoms such as angina, syncope, rarely sudden cardiac death. So, differential diagnosis with other ischemic or structural heart disease is crucial in the management of such patients. But there is no consistently successful diagnostic method. In the past, artificial diagnostic pneumothorax was used to document the absence of pericardium. However, it is not easily accepted due to excess morbidity and failure rate. Recently, echocardiography and more often, computed tomography, magnetic resonance imaging are used to confirm the diagnosis. We experienced a 52 years old male patient with atypical chest pain, who was diagnosed as complete left pericardial defect with computed tomography.

Purpose: The purpose of this study was to analyze articles published in the Journal of the Korean Academy of Nursing (JKAN) between 2010 and 2019, along with those published in three international nursing journals, to improve JKAN’s international reputation. Methods: The overall characteristics of JKAN’s published papers and keywords, study participants, types of nursing interventions and dependent variables, citations, and cited journals were analyzed. Additionally, the keywords and study designs, publication-related characteristics, journal impact factors (JIF), and Eigenfactor scores of International Journal of Nursing Studies (IJNS), International Nursing Review (INR), Nursing & Health Sciences (NHS), and JKAN were analyzed and compared. Results: Among the four journals, JKAN’s score was the lowest in both the journal impact factor and Eigenfactor score. In particular, while the JIF of INR and NHS has been continuously increasing; JKAN’s JIF has remained static for almost 10 years. The journals which had cited JKAN and those which JKAN had cited were mainly published in Korean. Conclusion JKAN still has a low IF and a low ranking among Social Citation Index (E) journals during the past 10 years, as compared to that of four international journals. To enhance JKAN’s status as an international journal, it is necessary to consider publishing it in English and to continuously improve the conditions of other publications.

The goal of this study was to evaluate the sonographic findings of thyroid metastases arising from non-thyroid primaries. The study over a 5-year period comprised nine patients who had histopathologically proven metastatic disease to the thyroid. Ultrasonography was available in all cases. Ultrasound-guided needle aspiration was performed on 10 suspected nodules as determined by ultrasound. The Ultrasonographic findings were analyzed in two different ways. The first analysis included only those nodules biopsed, and the second analysis included all the nodules, biopsed and non- biopsed. The primary neoplasms were breast carcinoma (n=6), uterine leiomyosarcoma (n=1), cervical carcinoma (n=1), and nasopharyngeal carcinoma (n=1). Excluding 2 nodules, the 8 remaining metastatic nodules exhibited ill-defined hypoechoic character with heterogeneous texture. The other two nodules showed relatively circumscribed iso- or hypo-echoic character with cystic portion. From the analysis of ultrasonographic findings including all thyroid nodules irrespective of pathologic proof, 7 cases - excluding the 2 cases from the 9 cases - showed unilateral or bilateral multiple nodules suspected of metastasis. There was no evidence of microcalcification in any thyroid nodules. In conclusion, the sonographic findings of the thyroid metastatic nodules were not specific, but unilateral or bilateral multiple suspected thyroid nodules without evidence of microcalcification may be suggestive of metastatic nodules among patients with a known primary non-thyroidal tumor.

The diagnosis of drowning is one of the most difficult in forensic pathology. One of the most common autopsy findings in drowning cases is a heavy, edematous lung as the result of water that is aspirated into the lungs before death. There are several controversial findings and arguments about the lung weight as a marker of drowning. The aim of the present study is to examine the difference in the lungs to the spleen weight ratio between seawater and freshwater drowning, compared with asphyxiation and acute cardiac death. This study compared the weight ratio of the lungs to the spleen for 29 cases of drowning (24 males, 5 females), 30 cases of mechanical asphyxiation (16 males, 14 females), and 37 cases of acute cardiac death (30 males, 7 females). This study presented significant differences in the lungs to the spleen weight ratio between drowning and the other causes of death . Therefore, these findings suggest that the ratio may be a useful index for accurate diagnosis of death by drowning.

PURPOSE: The purpose of this study is to assess the utility of PTBD spiral CT cholangiography, after infusion of contrast media through a PTBD tube, for evaluation of a biliary lesion after emergency PTBD due to severe jaundice. MATERIALS AND METHODS: Forty patients with emergency PTBD due to extrahepatic biliary obstruction were transferred to our clinic and prospectively studied. The causes of obstruction were 17 extrahepatic cholangiocarcinomas (including three Klatskin's tumors), seven pancreatic head carcinomas, six calculous diseases of the common bile duct, six periampullary lesions, two ampulla of Vater carcinomas, one gall bladder carcinoma with invasion of the common hepatic duct, and one cholangitis. Diagnosis was on the basis of pathologic, radiologic, and clinical findings. Pre-contrast CT scanning was performed. After the infusion of contrast media (iothalamate : normal saline=1:10) through a PTBD tube, spiral CT scans were obtained. After IV infusion of contrast media (Ultravist, 100cc), early- and delayed-phase spiral CT scans were obtained at 45 and 210 seconds, respectively, with an interscan interval of 5mm. 3-D CT cholangiograms were then reconstituted. Spiral CT without infusion of contrast media through a PTBD tube and PTBD spiral CT cholangiography were performed in 14 cases. The level of extrahepatic biliary obstruction was categorized as either upper, middle, or lower third. In 21 surgically confirmed cases, we evaluated the accuracy with which the level and cause of obstruction was determined; levels and causes during surgery and by as seen on PTBD cholaniography were compared. RESULTS: The levels of obstruction diagnosed on PTBD spiral CT cholangiography and on 3-D CT cholangiography corresponded in all cases to the levels during surgery and on PTBD cholangiography [upper third (n=7), middle third (n=12), lower third (n=21)], and the level diagnosed on spiral CT without infusion of contrast media through a PTBD tube corresponded to the level during surgery in ten of 14 cases. The cause of obstruction diagnosed on PTBD spiral CT cholangiography corresponded to pathologic findings in 19 of 21 cases. In 15 cases, 3-D CT cholangiography was diagnostically helpful. CONCLUSION: PTBD spiral CT cholangiography is a useful diagnostic method for determining the level and cause of biliary obstruction.

PURPOSE: To determine optimal scan time for the early phase of two-phase spiral CT and to evaluate its usefulness in the detection and assessment of extension of urinary bladder lesions. MATERIALS AND METHODS: In four normal adults, we performed dynamic scanning and obtained time-density curves for internal and external iliac arteries and veins, and the wall of the urinary bladder. Sixty patients with 68 lesions of the urinary bladder or prostate underwent precontrast and two-phase spiral CT scanning. After injection of 100ml of noninonic contrast material, images for the early and delayed phases were obtained at 60 seconds and 5 minutes, respectively. We measured CT H.U. of the wall, the lesion, and lumen of urinary bladder as seen on axial scanning, in each image in which the lesion was best shown. For the detection of bladder lesions and assessment of their extension, precontrast, early-, and delayed phase images were compared. RESULTS: Dynamic study of normal adults showed maximum enhancement of bladder wall between 60 and 100 seconds. The difference of CT H.U. between bladder wall and the lesion was greatest in the early phase. The best detection rate (98.5%) was seen during this phase, and for the detection of bladder lesion, this same phase was superior or equal (66/68,97.1%) to the delayed phase. The precontrast image was also superior or equal (31/68,45.6%) to that of the delayed phase. For the assessment of extension of bladder lesion, the early phase was superior (36/68,52.9%) to the delayed phase, and precontrast image was superior (1/68, 1.5%) to that of the delayed phase. For determining the stage of bladder cancer, the early phase was most accurate if the stages was below B2 or D, while for stage C, the delayed phase was most accurate. CONCLUSION: In two-phase spiral CT scanning, we consider the optimal time for the early phase to be between 60 and 100 seconds after injection of contrast material. For the detection and assessment of extension of urinary bladder lesion, the early phase was superior to the late phase, and for evaluation of the ureter, the delayed phase was useful. The precontrast image was inferior to that of the delayed phase. We suggest that for the detection and assessment of extension of urinary bladder lesion without scanning of the precontrast image, two-phase spiral CT is reliable.

BACKGROUND AND OBJECTIVES: Transradial coronary angiography and intervention are getting more popularity throughout the world because of lower incidence of puncture site complications and the patients have displayed early ambulation. However, radial arterial spasms and possible endothelial injury due to the small size of radial artery are troublesome. To overcome this problem, we investigated the usefulness of performing transradial coronary angiography using a single Judkins left catheter (JL). SUBJECTS AND METHODS: A total of 268 patients who underwent right transradial coronary angiography from June 2003 to December 2003 were enrolled for this prospective study. The Judkins Left 3.5(JL3.5), the Multipurpose (MP) and Amplatz Left (AL2 for males, AL1 for females) were assigned to be used in patients with a randomized protocol. The technical/angiographic success rate, procedural/fluoroscopic time and the frequency of stiffwire usage were assessed. RESULTS: Technical success was accomplished in 87 (96.7%) of the patients with a single JL3.5, in 90 (97.8%) of the patients with the MP and in 83 (96.5%) of the patients with the AL catheter. Successful angiography success was achieved in 77 (85.6%) of the patients using the JL3.5, in 71 (77.2%) of the patients using the MP and in 66 patients (76.7%) using the AL. The technical success rate (p=0.270) and the angiographic success rate (p= 0.162) showed no significant difference among the three catheters. The procedural time was 8.1+/-4.0 min in the JL3.5 group, 8.1+/-3.7 min in the MP group and 7.3+/-3.4 min in the AL group, respectively (p=0.431). Also, the fluoroscopic time was not different among the three groups. CONCLUSION: The JL3.5 catheter is an excellent tool for both coronary imaging and it is equally successful as compared with the MP and AL catheters. Therefore, the JL3.5 may be considered as the initial catheter that can be used, including for those difficult cases having tortuous vasculature of the subclavian artery and the ascending aorta, during transradial coronary angiography.

PURPOSE: This review article provides an overview of the trends of research papers on the health benefits of kimchi and kimchi lactic acid bacteria published from 1995 to 2017. METHODS: All publications from 1995 to 2017 regarding kimchi and kimchi lactic acid bacteria were collected, reviewed, and classified. This review article covers the publications of the health benefits of kimchi and kimchi lactic acid bacteria on experimental, clinical trials, and epidemiology studies. RESULTS: The number of publications on kimchi over the period were 590: 385 publications in Korean and 205 publications in English. The number of publications on the health benefits of kimchi and kimchi lactic acid bacteria were 95 in Korean and 54 in English. The number of publications on kimchi and kimchi lactic acid bacteria were 84 and 38, respectively, in the experimental models. Ten research papers on kimchi in clinical trials and 7 publications in epidemiology were found. Kimchi or kimchi lactic acid bacteria had protective effects against oxidative stress, mutagenicity, toxicity, cancer, dyslipidemia, hypertension, immunity, and inflammation in in vitro, cellular, and in vivo animal models. Moreover, kimchi had effects on the serum lipids, intestinal microbiota, iron status, obesity, and metabolic parameters in human clinical trials. In epidemiology, kimchi had effects on hypertension, asthma, atopic dermatitis, rhinitis, cholesterol levels, and free radicals. CONCLUSION: This review focused on the publications regarding the health benefits of kimchi and kimchi lactic acid bacteria, suggesting the future directions of studies about kimchi and kimchi lactic acid bacteria by producing a database for an evaluation of the health benefits of kimchi.

BACKGROUND: The aim of the present study was to determine the population-based prevalence of diabetes mellitus (DM) and prediabetes in a rural district of Daegu City, Korea. METHODS: Between August and November 2003, a community-based health survey of adults aged 20 years and older was performed in the rural district of Dalseong-gun in Daegu City. A total of 1,806 of all eligible individuals agreed to participate. Fasting plasma glucose was measured in all participants. Two hour oral glucose tolerance was measured in the 1,773 participants for whom there was neither an established diagnosis of DM nor evidence of DM according to fasting glucose levels. The prevalence of DM and prediabetes was determined according to the 2003 criteria of the American Diabetes Association. Subjects with prediabetes were classified into one of three categories of glucose intolerance: isolated impaired fasting glucose (IFG); isolated impaired glucose tolerance (IGT); or combined IFG and IGT. RESULTS: The prevalence of DM was 12.2%. The highest prevalence rates were observed in subjects in their seventies. A total of 34.7% of all subjects who were assigned a diagnosis of DM in the present study had not been diagnosed previously. The prevalence of prediabetes was 22.7%. The highest prevalence rates were observed in subjects in their fifties. CONCLUSION: The present study identified prevalence rates of 12.2% for DM (age-standardized prevalence rate [ASR], 6.8%), and 22.7% for prediabetes (ASR 18.5%). These results emphasize the need for community health promotion strategies to prevent or delay the onset of DM in individuals with prediabetes.
