PURPOSE: To present the ultrasonographic findings of an implanted absorbable mesh in patients who underwent breast partial resection. MATERIALS AND METHODS: We retrospectively analyzed the ultrasonographic findings of 18 patients who underwent breast partial resection with an absorbable mesh implant to minimize the breast deformity. Sonography was performed approximately 3 months after surgery (mean interval, 92 days). The presence of a capsule and cyst at the surgical site, the size of the cyst, internal content of the cyst, vascularity of the lesion, and presence of complications were analyzed. RESULTS: An ultrasound examination revealed a well-encapsulated cyst with regular capsule in 16 of the 18 patients. The longest diameter of the cyst varied from 3 cm to 10 cm. Among 16 cases that showed a well-encapsulated cyst, 11 cases showed an isoechoic nodular pattern in the cyst and in the remaining five cases, the internal nodular pattern was not seen. In two of the18 cases, an isoechoic nodular pattern without fluid content was seen for the lesions. A Doppler study revealed no vascularity in any of the lesions. CONCLUSION: Ultrasonographic findings of an implanted absorbable mesh, inserted in the surgical site to minimize breast deformity in patients that underwent breast partial resection, showed the presence of a well-encapsulated cyst with an internal isoechoic nodular pattern in the majority of the cases.

PURPOSE: To perform a frequency analysis of the extracolonic findings (ECF) of the CT colonography between symptomatic and asymptomatic patients. MATERIALS AND METHODS: Seventy-two consecutive symptomatic patients and sixty-three consecutive asymptomatic patients who underwent CT colonography were enrolled in this study. Non-contrast enhanced axial images were reviewed retrospectively to identify the ECF and classified them as major, moderate or minor important findings according to their potential clinical importance. The frequencies of each classification and ECF were analyzed and compared between two groups (symptomatic and asymptomatic). RESULTS: Eighty-two ECF were identified in 49 (68.1%) of the 72 symptomatic patients. The findings were classified as follows: major (8/49, 11.1%), moderate (17/49, 23.6%), minor (39/49, 54.2%). Sixty ECF were detected in 38 (60.3%) of the 63 asymptomatic patients. The findings were classified as follows: major (2/38, 3.2%), moderate (7/38, 11.1%), minor finding (35/63, 55.6%). No statistically significant differences were found between the two groups (p > 0.05) for the overall ECF frequency. However, a significantly higher frequency of major or moderate ECF was observed in symptomatic patients (30.6%) compared to asymptomatic patients (12.7%) (p < 0.05). CONCLUSION: The overall ECF frequency was similar between symptomatic and asymptomatic patients; however, the frequency of clinically important ECF (major or moderate) was higher in symptomatic patients, compared to asymptomatic patients. This result suggests that the major or moderate ECF required a further work up or treatment in symptomatic patients.

Neonatal lupus erythematosus is a syndrome characterized by congenital heart block and photo-distributed papulosquamous eruption, in which multi-organ involvement is not common. We report a case of neonatal lupus erythematosus with pancytopenia and transient bradycardia. The neonate was born to a mother with systemic lupus erythematosus. Both of the neonate and the mother were positive for anti Ro/SS-A antibody.

Pulsed Doppler echocardiography was performed before and five to fifteen days (mean, 9.3 days) after mitral valve surgery to evaluate the change of pulmonary arterial pressure in 80 patients (29 males and 51 females) with mitral valve disease by preejection period (PEP)/acceleration time (AT) ratio at the right ventricular outflow tract. In 13 patients with pulmonary hypertension (mean pulmonary arterial pressure equal to or greater than 20mmHg), Doppler echocardiography was followed three to twelve months after operation. In 76 patients with a mitral valve prosthesis (15 patients with the Bjork-Shiley valve, 28 patients with the Ionescu-Shiley valve, and 33 patients with the St. Jude valve), mean transmitral pressure gradient and pressure-half time were estimated by continuous wave Doppler echocardiography five to fifteen days after operation. 1) PEP/AT Ratio by pulsed Doppler echocardiography correlated well with the mean pulmonary arterial pressure gradient by cardiac catheterization (r=0.83, p<0.001). 2) After mitral valve surgery, PEP/AT ratio decreased significantly (p<0.001). In group with mean pulmonary arterial pressure equal to or greater than 40mmHg, immmediate postoperative PEP/AT ratio was greater (P<0.05) than that in group with mean pulmonary arterial pressure less than 20 mmHg, but, difference between the preoperative and postoperative PEP/AT ratio was much greater (P<0.001) than that in group with mean pulmonary arterial pressure between 20 and 39 mmHg. 3) In 13 patients, on whom repeated Doppler echocardiography performed, PEP/AT ratio decreased immediately after mitral valve surgery (p<0.001). After then, it decreased further, but, the amount of the decrease was much smaller than immediate one (p<0.001). 4) There was no significant difference in postoperative PEP/AT ratio among the different prosthesis. Mean transmitral pressure gradient and pressure half-time of the Bjork-Shiley, Ionescu-Shiley, and St, jude valves were 3.1 mmhg and 67.3 msec, 2.9 mmHg and 65.3 msec, and 2.7 mmhg and 60.2 msec, repectively. The St.Jude valve had somewhat smaller mean transmitral pressure gradient and pressure half-time, but there was no statistical significance. In conclusion, elevated pulmonary arterial pressure in patients with mitral valve disease decreased greatly within 15 days after operation, and Doppler echocardiography was a useful method in the follow-up of prosthetic mitral valve function.

PURPOSE: The Infertility Self-Efficacy scale (ISE) is an instrument used to identify infertility-related self-efficacy. The purpose of this study was to assess the reliability and validity of the Korean version of the ISE developed by Cousineau et al. in 2006. METHODS: The translated instrument was pilot-tested and administered to 314 women and men with a diagnosis of infertility. For estimating reliability, testeretest and the internal consistency reliability coefficients were calculated. Validity was evaluated through content validity, concurrent validity, and construct validity with exploratory and confirmatory factor analyses. RESULTS: The internal consistency reliability was satisfactory (Cronbach's alpha = .92, item-total correlations = .44–.80), and the intra-class correlation coefficient was .84 (p < .001). The overall content validity index was 98.1%, and the concurrent validity coefficient (correlations between the ISE scale and general self-efficacy scale) was .31 (p < .001). The final model's fit indexes were acceptable (CFI = .96, NFI = .93, RMSEA = .07, GFI = .94, and SRMR = .03), indicating good construct validity. CONCLUSION: The Korean version of the ISE has high reliability (stability and homogeneity), and good content, concurrent, and construct validity (EFA and CFA). Validated Korean version of the ISE may help nurses identify infertility-related self-efficacy.

PURPOSE: To compare the lesion conspicuity of radiofrequency ablation (RFA) zones among MR sequences according to time in the normal rabbit liver. MATERIALS AND METHODS: RFA zones were created in 12 rabbit livers with a 17-gauge internally cooled electrode (1-cm active tip, 30 Watts, 3 minutes). Three rabbits were sacrificed immediately, three days, two weeks, and six weeks after the RFA procedure, respectively. Before sacrifice, T1-, T2-weighted images (WI), and gadolinium-enhanced (GE)-T1WI images were obtained. The lesion conspicuity of the RFA zone and the contrast-to-noise ratio (CNR) of the RFA zone to the liver parenchyma were analyzed and compared among the MR sequences according to time. RESULTS: On T1WI, the RFA zones were only clearly seen on acute phase. On T2WI, the RFA zones were clearly seen on all phases except the hyperacute phase. On GE T1WI, the RFA zones were clearly seen on all phases. The CNRs of the RFA zone to the liver parenchyma of GE-T1WI (8.1-12.4) were significantly higher than the CNRs of TIWI (1.6-2.7) and T2WI (1.7-6.3) on all phases (p < 0.05), but the visual lesion conspicuity between GE T1WI and T2WI were similar. CONCLUSION: On hyperacute phase, GE T1WI showed better lesion conspicuity of the RFA zone than T1WI and T2WI. On other phases, GE T1WI and T2WI showed similar lesion conspicuity.

Neuroendocrine carcinomas mostly occur in the gastrointestinal tract, lung and pancreas. The gallbladder is an uncommon organ for a neuroendocrine carcinoma and it is difficult to diagnose before gallbladder surgery. Owing to its rare occurrence its natural course and treatment are not definitely established. A 71-year-old woman was hospitalized with intermittent abdominal pain and nausea. Abdominal computed tomography showed multiple masses of the gallbladder obstructing the biliary tract. From endoscopic ultrasonography we suspected carcinoma of the gallbladder that was infiltrating a common bile duct. A biopsy was taken using endoscopic retrograde cholangiopancreatography (ERCP) and the mass was diagnosed as a neuroendocrine carcinoma of the gallbladder. Here we report a case of a neuroendocrine carcinoma of the gallbladder confirmed by endoscopic biopsy, and provide a review of the literature.

PURPOSE: This study evaluated the psychometric properties of the Korean version of Yale Food Addiction Scale for Children (YFAS-C). METHODS: Participants were 419 young adolescent students (11~15 years old). The content validity of the expert group was calculated as the content validity index (CVI) after the translation and reverse translation process of the 25 items of the YFAS-C. The multitrait-multimethod matrix (MTMM) method was used to verify the construct validity; the generalized linear model (GLM) was used to evaluate the concurrent and incremental validity. Reliability was calculated as Kuder-Richardson-20 (KR-20) and Spearman-Brown coefficients. RESULTS: The CVI of the 25 items was greater than the item-level CVI .80 and the scale-level CVI .90. The Korean version of YFAS-C had verified convergent validity in emotional eating and external eating and discriminant validity in restrained eating. In addition, it had verified concurrent validity in emotional eating and external eating. Finally the incremental validity of the Korean version of YFAS-C was statistically significant on BMI. Reliability was KR-20 α=.69 and the Spearman-Brown coefficient was .64. CONCLUSION: The Korean version of YFAS-C is a valid and reliable scale for measuring the severity of food addiction; it can be a useful scale for preventing obesity by predicting food addiction early.
