PURPOSE: In order to find out how frequently and what kind of extra-cardiac anomalies (CAs) is associated with congenital heart disease (CHD) in general and in each CAs, autopsies with congenital cardiovascular malformations were studied. METHODS: Autopsy files of Seoul National University Children's Hospital from 1991 to 1995 were reviewed to find cases of CHDs. Other extra-CAs were tabulated from the records of autopsy files. The study population was comprised of 156 cases (86 still birth or product of terminated pregnancy; 66 livebirth; 4 unknowns-whether still birth or livebirth). RESULTS: The sex ratio was 1.14:1 males to females. In still birth cases, gestational age ranged from 16 to 42 weeeks and in live birth cases, age ranged from 1 day to 1 year 7 months (mostly neonates). The ventricular septal defect (VSD) was the most common CA, followed by coarctation of aorta, tetralogy of Follot in this order of frequency. No extra-CA was found in 55 cases, 1 extra-CA in 54 cases, 2 extra-CAs in 35 cases, 3 or more extra-CAs in 12 cases. VSD was commonly associated with Edward syndrome and holoprosencephaly, tetralogy of Fallot with holoprosencephaly, and coarctation with cystic hygroma. The most commonly involved organ system was the central nervous system followed by the digestive system, facial anomaly, and so on. Chromosomal anomaly associated with CHDs was 24 cases. Common individual anomalies were cystic hygroma, Edward syndrome, holoprosencephaly, and so on. CONCLUSION: As the fetus and infants with CHD have high incidence of associated extra-CAs, collaborative works involving dysmorphologist, geneticist, pathologist, surgeons, and pediatric cardiologist are needed. For further studies of CA and extra-CAs, a systematic database andprecise medical records and interdepartmental collaboration are necessary.

PURPOSE: Myocardial scintigraphy has been reported to be useful in adults, but its usefulness in children is limited. This study was done to determine the feasibility and accuracy of 99mTc-MIBI SPECT(sestamibi , methoxy-isobutyl-isonitrarite myocardial single emirs sion computed tomography, Dp-SPECT) after dipyridamole infusion to detect coronary obstructive lesions in Kawasaki disease(KD). METHODS: Dp-SPECT was performed in 21 control(group 1), 8 with coronary aneurysm(group 2) and 16 with coronary obstructive lesion(group 3) in children with KD. The spatial distribution of Dp-SPECT was determined and analyzed visually. Group 2 and 3 underwent coronary angiogram within 3 months of Dp-SPECT. RESULTS: Chest pain occurred more frequently in group 2. No subject required supplemental oxygen or were complicated by myocardial ischemia. The specificity of Dp-SPECT for control subject was 95% & 62% if using a cut-off criterion of abnormality, utilizing moderate or mild perfusion defect, respectively. The false positive rate was high in anterior, apical and anteroseptal segments but not related to age. The abnormalities found on Dp-SPECT was observed in 25% of aneurysmal coronary arteries but not related to its size. The sensitivity, specificity, and accuracy of Dp-SPECT was 100%, 84.5% and 79% in coronary stenosis greater than 75%, respectively. CONCLUSION: The interpretation of Dp-SPECT should be careful in KD because of discrepancies between Dp-SPECT & angiography, But DP-SPECT is noninvasive and easily applicable. It monitors the occurrence and progression of coronary stenosis due to KD. Besides Dp-SPECT may be applicable after arterial switch operation or to myocardial sinusoid.

PURPOSE: The purpose of this study was to investigate what factors are affecting job-seeking stress in nursing students. METHODS: Subjects were 463 students from two 3-year and two 4-year colleges of nursing in K-Province in Korea. Data was collected from self-administered questionnaires. t-test, ANOVA, Pearson's and Spearman's correlation coefficients, and hierarchical multiple regression with dummy variables were used for statistical analysis of data. RESULTS: Job-seeking stress was significantly different by school system (t=2.76, p=.006), family economic status (F=3.40, p=.005), characteristics (t=1.99, p=.047), academic achievement (F=6.54, p=.002), current weight control status (t=2.23, p=.026), times of cosmetic surgery (r=.11, p=.022), self-esteem (r=-.47, p<.001) and appearance stress (r=.40, p<.001). However, after controlling for general characteristics, self-esteem, and perceived appearance stress, job-seeking stress was significantly different by grade (1st vs 3rd, beta=0.163, p<.001), academic achievement (low vs. high, beta=-0.121, p=.0321), self-esteem (beta=-0.224, p<.001), and appearance stress (beta=0.099, p<.001). The explanation power of self-esteem on job-seeking stress was greater compared with that of appearance stress. CONCLUSION: Results of this study suggest that it is necessary for nursing students to develop intervention program aimed at reducing job-seeking stress, and it would be effective to focus on improving self-esteem for them.

PURPOSE: To plug the biopsy site in eight patients with coagulopathy who had undergone percutaneous liverbiopsy. To this end, gelfoam cartridge was used as a sealant. MATERIALS AND METHODS: Using an 18G Tru-Cut-typedisposible automated biopsy gun(Soo Ho Medi-tech, Seoul, Korea) and under US guidance, eight patients underwentpercutaneous liver biopsy. After the gun had fired, the biopsy specimen in the inner stylet was retrieved whilethe outer cannula was held in place ; the cannula was then used to plug the biopsy tracks with gelfoam, using twoor three cartridges. If bleeding occurred, this was controlled by the use of more gelfoam cartridges. RESULTS: Diagnostic target tissue was obtained in seven of the eight patients(87.5%). Hepatocellular carcinoma wasdiagnosed in five cases and metastatic cancer in two. Profuse bleeding was observed in one patient(12.5%) andresolved by gelfoam plugging. CONCLUSION: We believe that in patients with coagulopathy who are required toundergo liver biopsy plugging the liver biopsy track with gelfoam cartridge is a simple, safe and useful method.

Myofibroblastoma of the breast is a rare benign mesenchymal tumor that is known to occur in middle-aged and elderly men, yet there are some recent reports showing no certain difference for the gender distribution of this malady. Localized mass excision can usually provide a complete cure. To the best of our knowledge, there have been no reports of metastasis or recurrence of this tumor. Here we describe the sonographic findings of a case of recurrent myofibroblastoma after surgical excision for suspected fibroadenomas in both breasts of a 25-year-old woman.

Background: /Aim: This study aimed to determine the diagnostic performance of 2022 Korean Liver Cancer Association-National Cancer Center (KLCA-NCC) imaging criteria compared with the 2018 KLCA-NCC for hepatocellular carcinoma (HCC) in high-risk patients using magnetic resonance imaging (MRI). Methods: This retrospective study included 415 treatment-naïve patients (152 patients who underwent extracellular contrast agent [ECA]-MRI and 263 who underwent hepatobiliary agent [HBA]-MRI; 535 lesions, including 412 HCCs) with a high risk of HCC who underwent contrast-enhanced MRI. Two readers evaluated all lesions according to the 2018 and 2022 KLCA-NCC imaging diagnostic criteria, and the per-lesion diagnostic performances were compared. Results: In “definite” HCC category of both 2018 and 2022 KLCA-NCC, HBA-MRI showed a significantly higher sensitivity for the diagnosis of HCC than ECA-MRI (77.0% vs. 64.3%, P=0.006) without a significant difference in specificity (94.7% vs. 95.7%, P=0.801). On ECAMRI, “definite” or “probable” HCC categories of the 2022 KLCA-NCC had significantly higher sensitivity than those of the 2018 KLCA-NCC (85.3% vs. 78.3%, P=0.002) with identical specificity (93.6%). On HBA-MRI, the sensitivity and specificity of “definite” or “probable” HCC categories of both 2018 and 2022 KLCA-NCC were not significantly different (83.3% vs. 83.6%, P>0.999 and 92.1% vs. 90.8%, P>0.999, respectively). Conclusions In “definite” HCC category of both 2018 and 2022 KLCA-NCC, HBA-MRI provides better sensitivity than ECA-MRI without compromising specificity. On ECA-MRI, “definite” or “probable” HCC categories of the 2022 KLCA-NCC may improve sensitivity in the diagnosis of HCC compared with the 2018 KLCA-NCC.

Purpose: The aim of the present study was to evaluate the per-lesion sensitivity and specificity of the Korean Liver Cancer Association–National Cancer Center (KLCA-NCC) 2022 criteria for the noninvasive diagnosis of hepatocellular carcinoma (HCC), with intraindividual comparison of the diagnostic performance of magnetic resonance imaging with extracellular agents (ECA-MRI) and hepatobiliary agents (HBA-MRI). Materials and Methods: Patients at high risk for HCC who were referred to a tertiary academic institution for hepatic lesions with size ≥ 10 mm between July 2019 and June 2022 were enrolled. A total of 91 patients (mean age, 58.1 years; 76 men and 15 women) with 118 lesions who underwent both ECA-MRI and HBA-MRI were eligible for final analysis. The per-lesion sensitivities and specificities of the KLCA-NCC 2022 criteria using ECA-MRI and HBA-MRI were compared using McNemar’s test. Results: The 118 lesions were 93 HCCs, 4 non-HCC malignancies, and 21 benign lesions. On HBA-MRI, the “definite” HCC category showed significantly higher sensitivity than ECA-MRI (78.5% vs. 58.1%, p < 0.001), with identical specificity (92.0% vs. 92.0%, p > 0.999). For “probable” or “definite” HCC categories, there were no differences in the sensitivity (84.9% vs. 84.9%, p > 0.999) and specificity (84.0% vs. 84.0%, p > 0.999) between ECA-MRI and HBA-MRI. Conclusion The “definite” HCC category of the KLCA-NCC 2022 criteria showed higher sensitivity in diagnosing HCC on HBA-MRI compared with ECA-MRI, without compromising specificity. There were no significant differences in the sensitivity and specificity of “probable” or “definite” HCC categories according to ECA-MRI and HBA-MRI.

Purpose: Acquisition time reduction in diffusion-weighted imaging (DWI) can be achieved by the combining multiband and variable-rate selective excitation (MB-VERSE). This study attempted to evaluate and compare the image quality (IQ) and focal lesion detectability of the respiratory-triggered MB-VERSE DWI with conventional DWI for liver magnetic resonance imaging. Materials and Methods: The acquisition time, IQ, and focal lesion detectability of MBVERSE DWI and conventional DWI were compared in 144 patients. Qualitative (overall IQ, IQ at the liver dome, sharpness of the liver margin, and degree of artifacts) and quantitative (signal-to-noise ratio [SNR], contrast-to-noise ratio [CNR], and apparent diffusion co efficient) IQ parameters were compared with the Wilcoxon signed-rank test. The diagnostic accuracy for focal lesion detectability was estimated with the mean figure of merit (FOM) from the area under the jackknife alternative free-response receiver operating characteristic curve. Results: The MB-VERSE DWI exhibited significantly shorter scan time (153.1 ± 34.5 s vs.225.1 ± 33.0 s, p < 0.001), poorer qualitative IQ (3.4 vs. 3.9, p < 0.001), lower SNR (34.4 vs. 50.0, p < 0.001), but comparable CNR (57.5 ± 49.0 vs. 78.9 ± 75.6, p = 0.070) compared to those of the conventional DWI. The MB-VERSE DWI exhibited similar per-lesion sensitivities (85.1%–88.1% vs. 88.1%–92.5%) and specificities (99.7%–99.8% vs. 99.5%–99.8%) of focal lesion detectability (p > 0.050) and similar diagnostic accuracy (FOM, 0.958 vs.0.957, p = 0.583) compared to those of the conventional DWI. Conclusion MB-VERSE DWI exhibited a significantly shorter acquisition time than conventional DWI, with compromised overall IQ and lower SNR but preserved CNR and focal liver lesion detectability. MB-VERSE DWI may be a useful alternative for patients requiring a short acquisition time.

PURPOSE: The renin-angiotensin-aldosterone system activation has been suggested as a potential risk factor for renal progression in autosomal dominant polycystic kidney disease (ADPKD). This study was performed to evaluate urinary angiotensinogen as a biomarker of renal progression in ADPKD. METHODS: Patients with estimated glomerular filtration rate (eGFR) > or =30 mL/min/1.73m2 were enrolled in the study. Specimens (blood and urine) and computed tomography (CT) were taken from each subject. The eGFR was calculated by 4-variable MDRD equation and total kidney volume (TKV) was measured from CT images by modified ellipsoid method. Urinary angiotensinogen (AGT) and neutrophil gelatinaseassociated lipocalin (NGAL) were measured by ELISA. The concentration of AGT was adjusted with random urine creatinine (Cr). The association between urinary biomarkers, TKV and eGFR were evaluated. RESULTS: A total of 59 (M:F=31:28) subjects were enrolled in the study and their mean age was 46 years. The eGFR and TKV at the enrollment were 77.3+/-15.6 mL/min/1.73m2 and 1389.8+/-925.1 mL, respectively. Log AGT/Cr was associated with TKV (r2=0.117, p=0.01) in the earlier stage of disease (TKV<3,000 mL). However, it did not show significant correlation with eGFR. Log NGAL was not associated with either TKV or eGFR. Urinary AGT/Cr was closely related to the number of anti-hypertensive medication, TKV, and the presence of albuminuria, although there was no correlation with plasma renin activity or aldosterone level. CONCLUSION: Urinary angiotensinogen may be a useful biomarker of disease progression in ADPKD patients.
