1.Hemangiomas with the Variable Manifestations on Breast Imaging: Three Case Reports.
Journal of the Korean Society of Medical Ultrasound 2010;29(4):303-307
Benign hemangiomas of the breast have been rarely reported in the clinical literature. The imaging appearance ranges from probably benign to suspicious for malignancy. We report three cases of breast hemangiomas with variable manifestations on mammography, ultrasonography, and magnetic resonance imaging.

BACKGROUND/AIMS: The role of radiofrequency ablation (RFA) remains uncertain in patients with viable hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE). METHODS: A total of 101 patients (April 2007 to August 2010) underwent RFA for residual or recurrent HCC after TACE. We analyzed their long-term outcomes and predictive factors. RESULTS: The overall survival rates after RFA were 93.1%, 65.4%, and 61.0% at 1, 3, and 5 years, respectively. Predictive factors for favorable overall survival were Child-Pugh class A (hazard ratio [HR], 3.45; p=0.001), serum alpha-fetoprotein (AFP) level <20 ng/mL (HR, 2.90; p=0.02), and recurrent tumors after the last TACE (HR, 3.14; p=0.007). The cumulative recurrence-free survival rate after RFA at 6 months was 50.1%. Predictive factors for early recurrence (within 6 months) were serum AFP level > or =20 ng/mL (HR, 3.02; p<0.001), tumor size > or =30 mm at RFA (HR, 2.90; p=0.005), and nonresponse to the last TACE (HR, 2.13; p=0.013). CONCLUSIONS: Patients with recurrent or residual HCC who undergo prior TACE show a favorable overall survival, although their tumors seem to recur early and frequently. While good liver function, a low serum AFP level, and recurrent tumors were independent predictive factors for a favorable overall survival, poor response to TACE, a high serum AFP level, and large tumors are associated with early recurrence.

Objectives:
Demoralization, which results from the inability to cope, is characterized by hopelessness, helplessness, and loss of the meaning and purpose of life. Although demoralization is prevalent in patients with chronic illness, including cancer, a Korean version of the scale has not been developed and validated. Thus, we translated into Korean and validated a version of the Demoralization Scale-II (DS-II-Kr) for cancer patients.
Methods:
This cross-sectional study recruited cancer patients and survivors who visited a mental health clinic in a cancer hospital. Internal consistency, test-retest reliability, and concurrent validity of DS-II-Kr were assessed. Additionally, the construct validity of two sub-factors was evaluated using confirmatory factor analysis. The optimal DS-II-Kr cut-off point was determined by logistic regression analysis based on the distress cut-off in the Hospital Anxiety-Depression Scale (HADS).
Results:
This study included 105 participants. The mean and standard deviation for total DS-IIKr scores were 11.9 and 7.6, respectively. The scale demonstrated good internal consistency and test-retest reliability. Goodness-of-fit analysis was moderate for the Meaning and Purpose subscale, and a good fit was found for the Distress and Coping Ability subscale. The DS-II-Kr cut-off value based on HADS was 10 (≤10 vs. >10).
Conclusion
The DS-II-Kr is a useful tool for assessing demoralization in clinical and research settings. However, further studies are needed to confirm the optimal DS-II-Kr cut-off score. External validation in other populations is also needed.

Background:
We aimed to assess the risk of maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and early abortive outcomes after the association between coronavirus disease 2019 (COVID-19) vaccination during the preconceptional period and preclinical pregnancy, which are likely to be inadvertent vaccination.
Methods:
We used data from the Korea Disease Control and Prevention Agency-COVID19-National Health Insurance Service cohort from December 2020 to December 2021. The vaccinated pregnant women were matched to unvaccinated pregnant controls at a 1:4 ratio.The risks of SARS-CoV-2 infection and intensive care unit (ICU) admission within 14 days of infection were analyzed to assess its effectiveness. For safety measures, the adjusted relative risks (aRRs) of early abortive outcomes for the first COVID-19 vaccination during the preconceptional and preclinical periods were calculated considering covariates. We compared the risk of early abortion between mRNA and viral vector vaccines.
Results:
The overall COVID-19 vaccination rates during the preconceptional period and preclinical pregnancy were 3.1% (6,662/215,211) and 2.6% (5,702/215,211), respectively.The cumulative incidence of ICU admission within 14 days of SARS-CoV-2 infection was 6/100,000 in the unvaccinated group, whereas there were no ICU admissions in the vaccinated groups. The risks of early abortive outcomes were not significantly different between the preconceptional vaccination group and the unvaccinated group (aRR, 1.04; 95% confidence interval [CI],0.99–1.10) or between preclinical pregnancy vaccination and their matched controls (1.02; 95% CI, 0.96–1.08). mRNA and viral vector vaccines have shown similar risks for early abortive outcomes and miscarriages.
Conclusion
Our findings have provided compelling evidence regarding the effectiveness and safety of COVID-19 vaccination prior to and during early pregnancy. Further research is required to extend the safety and efficacy profiles of COVID-19 vaccines to pregnant women and their babies.

BACKGROUND/AIMS: The efficacy of tenofovir disoproxil fumarate (TDF) for the treatment of chronic hepatitis B (CHB) patients following prior treatment failure with multiple nucleos(t)ide analogues (NAs) is not well defined, especially in Asian populations. In this study we investigated the efficacy and safety of TDF rescue therapy in CHB patients after multiple NA treatment failure. METHODS: The study retrospectively analyzed 52 CHB patients who experienced failure with two or more NAs and who were switched to regimens containing TDF. The efficacy and safety assessments included hepatitis B virus (HBV) DNA undetectability, hepatitis B envelop antigen (HBeAg) seroclearance, alanine transaminase (ALT) normalization and changes in serum creatinine and phosphorus levels. RESULTS: The mean HBV DNA level at baseline was 5.4 +/- 1.76 log10 IU/mL. At a median duration of 34.5 months of TDF treatment, the cumulative probabilities of achieving complete virological response (CVR) were 25.0%, 51.8%, 74.2%, and 96.7% at 6, 12, 24, and 48 months, respectively. HBeAg seroclearance occurred in seven of 48 patients (14.6%). ALT levels were normalized in 27 of 31 patients (87.1%) with elevated ALT at baseline. Lower levels of HBV DNA at baseline were significantly associated with increased CVR rates (p < 0.001). However, CVR rates did not differ between TDF monotherapy or combination therapy with other NAs, and were not affected by mutations associated with resistance to NAs. No significant adverse events were observed. CONCLUSIONS: TDF is an efficient and safe rescue therapy for CHB patients after treatment failure with multiple NAs.

High prevalence of diabetes mellitus in patients with liver cirrhosis has been reported in many studies. The aim of our study was to evaluate the relationship of hepatic fibrosis and steatosis assessed by transient elastography with diabetes in patients with chronic liver disease. The study population consisted of 979 chronic liver disease patients. Liver fibrosis and steatosis were assessed by liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) on transient elastography. Diabetes was diagnosed in 165 (16.9%) of 979 patients. The prevalence of diabetes had significant difference among the etiologies of chronic liver disease. Higher degrees of liver fibrosis and steatosis, assessed by LSM and CAP score, showed higher prevalence of diabetes (F0/1 [14%], F2/3 [18%], F4 [31%], P<0.001; S0/1 [15%], S2 [17%], S3 [26%], P=0.021). Multivariate analysis showed that the independent predictive risk factors for diabetes were hypertension (OR, 1.98; P=0.001), LSM F4 (OR, 1.86; P=0.010), male gender (OR, 1.60; P=0.027), and age>50 yr (OR, 1.52; P=0.046). The degree of hepatic fibrosis but not steatosis assessed by transient elastography has significant relationship with the prevalence of diabetes in patients with chronic liver disease.

BACKGROUND/AIMS: Hepatitis-B-related acute-on-chronic liver failure has a poor prognosis. However, the advent of potent oral antiviral agents means that some patients can now recover with medical treatment. We aimed to identify the prognostic factors for hepatitis-B-related acute-on-chronic liver failure including the initial as well as the dynamically changing clinical parameters during admission. METHODS: Sixty-seven patients were retrospectively enrolled from 2003 to 2012 at Samsung Medical Center. The patients were classified into three categories: Recovery group (n=23), Liver transplantation group (n=28), and Death group (n=16). The Liver transplantation and Death groups were combined into an Unfavorable prognosis group. We analyzed the prognostic factors including the Model for End-Stage Liver Disease (MELD) scores determined at 3-day intervals. RESULTS: A multivariable analysis showed that the unfavorable prognostic factors were a high initial MELD score (> or =28) (odds ratio [OR] =6.64, p=0.015), moderate-to-severe ascites at admission (OR=6.71, P=0.012), and the aggravation of hepatic encephalopathy during hospitalization (> or =grade III) (OR=15.41, P=0.013). Compared with the baseline level, significant reductions in the MELD scores were observed on the 7th day after admission in the Recovery group (P=0.016). CONCLUSIONS: Dynamic changes in clinical parameters during admission are useful prognostic factors for hepatitis-B-related acute-on-chronic liver failure.

A 51-year-old male patient with chronic hepatitis B was referred to our hospital due to a 1-cm liver nodule on ultrasonography. Alpha-fetoprotein (AFP) was slightly elevated. The nodule showed prolonged enhancement on dynamic liver magnetic resonance imaging and appeared as a hyperintensity on both diffusion-weighted and T2-weighted imaging. The nodule was followed up because it was small and typical findings of hepatocellular carcinoma (HCC) were not observed in the dynamic imaging investigations. However, liver contrast-enhanced ultrasonography performed 1 month later showed enhancement during the arterial phase and definite washout during the delayed phase. Also, AFP had increased to over 200 ng/mL even though AST and ALT were decreased after administering an antiviral agent. He was presumptively diagnosed as HCC and underwent liver segmentectomy. Microscopy findings of the specimen indicated bile duct adenoma. After resection, the follow-up AFP had decreased to within the normal range. This patient represents a case of bile duct adenoma with AFP elevation mimicking HCC on contrast-enhanced ultrasonography.
