1.Primary adenosquamous carcinoma of the liver: a case report.
Clinical and Molecular Hepatology 2016;22(4):503-508
Adenosquamous carcinoma of the liver is a rare variant of cholangiocarcinoma. It is known to be a highly aggressive tumor with a poor prognosis, but its pathogenesis remains unclear owing to limited data in the literature. We report a case of 56-year-old woman who presented with a 1-week history of epigastric pain. Magnetic resonance imaging revealed a 6.5-cm ill-defined mass with low signal intensity in the left lobe of the liver, which was suspicious of cholangiocarcinoma. The patient underwent left hemihepatectomy. Microscopically, the tumor consisted of malignant glandular and squamous components and staged as pT2aN1. Despite postoperative chemoradiation, the patient had recurrence 8 months after surgery.

PURPOSE: This was a methodological research to develop an instrument to assess the emotional response of family members of physically restrained patients. METHODS: A primary instrument with 68 questions was developed based on literature review and semi-structured interviews with family members. A group of experts revised individual questions and removed 4 irrelevant questions. This secondary instrument, then, was tested with 199 family members of physically restrained patients in intensive care units of a university hospital. The validity and reliability of the instrument were tested by factor analysis. RESULTS: After item analysis, 3 questions with a correlation coefficient under .30 were discarded and the questions with a factor loading under .45 on Varimax Rotation were also removed. After factor analysis on the final 37 questions, 7 factors were identified; avoidance, shock, helplessness, grudge, depression, anxiousness, and acceptance. The total variance explained was 55.63%. The reliability of this instrument was 0.93 of Cronbach's alpha. CONCLUSION: This instrument was statistically reliable and valid to measure family's emotional response to physical restraints of the patients. This instrument can be useful in assessing the effects of nursing interventions for family members of restrained patients.

PURPOSE: Because of recent global and domestic issues regarding the safety of food, there is growing concern over food safety and interest in the country-of-origin for food ingredients from restaurants. This study was conducted to reveal the influence of consumer level of knowledge and awareness regarding restaurants and the country-of-origin labeling. METHODS: To accomplish this, a primary survey of adults aged over 20 years old was conducted to measure customers' knowledge regarding country-of-origin labeling for restaurants. Respondents were then divided into a lower group and an upper group based on their level of knowledge to evaluate significant differences between groups. A total of 437 of 460 questionnaires were analyzed. RESULTS: The average knowledge score regarding country-of-origin labeling for restaurants was 6.3 out of 10. Additionally, there were significant differences between the lower and upper group in terms of the final education level and occupation. CONCLUSION: It is necessary to develop guidelines and public relations for country-of-origin labeling of restaurants.

PURPOSE: Intussusception is one of the most common cause of childhood intestinal obstructions. Early diagnosis is essential to avoid treatment delays, which can increase morbidity and mortality. METHODS: In order to evaluate the factors contributing to air-reduction failure, we reviewed cases of childhood intussusception admitted via the ER and managed by air enema reduction from 1994 to 1998. They were divided into two groups and compared retrospectively by using medical records. Group I was the operation group after air-reduction failure, and group II was the air-reduction group. RESULTS: In 319 cases (279 patients), group I consisted of 112 cases (110 patients), and group II consisted of 207 cases (169 patients). No differences in age, sex, body weight, location of intussusception, laboratory findings (leukocytosis and thrombocytosis), presence of bloody stool, and body temperature were noted between the two groups. Factors significantly contributing to air-reduction failure were duration of symptoms, type of intussusception and a few physical findings (abdominal distension, palpable mass, lethargy, and vomiting). The recurrence rate of group I was significantly lower than that of group II, and most recurrences developed in the first postoperative month. CONCLUSION: Childhood intussusceptions of a non-ileocolic type with longer durations of symptoms and severe clinical findings have a higher chance of air-reduction failure.

BACKGROUND: Xpert Flu (Cepheid, USA) allows for fully automated real-time RT-PCR using a single-use disposable cartridge. The aim of this study was to evaluate Xpert Flu for the detection of influenza A virus and subtype A/H1N1/2009 pandemic virus. METHODS: We conducted a prospective comparison study for Xpert Flu with the RealTime ready Influenza A/H1N1 Detection Set (Roche Diagnostics, Germany). Analytical specificities of the assays were determined by testing commonly encountered respiratory viral pathogens, including parainfluenza virus type 1/2/3, rhinovirus A, rhinovirus B, metapneumovirus, adenovirus, and coronavirus. The analytical sensitivities and workflow of both methods were also assessed. RESULTS: A total of 102 consecutive clinical specimens were tested by both methods. Total agreement between the two methods was estimated to be 99.0% (101/102): 11 A/H1N1/2009 and 3 seasonal influenza A by the RealTime ready Influenza A/H1N1 Detection Set; 10 and 3 by Xpert Flu. No cross-reactivity was observed between influenza A/H1N1/2009 and other respiratory viral pathogens in either method. The limits of detection of the RealTime ready Influenza A/H1N1 Detection Set and Xpert Flu were 500 TCID50/mL and 20 TCID50/mL, respectively. Xpert Flu required 85 minutes (10 minutes of hands-on time) for processing, while RealTime ready Influenza A/H1N1 Detection Set took 128 minutes (30 minutes of handson time). CONCLUSION: The results of Xpert Flu were comparable to those of the RealTime ready Influenza A/H1N1 Detection Set. It is of note that the fully automated and closed system of Xpert Flu could be advantageous for reducing hands-on time and for preventing cross-contamination during the testing process.

This study was conducted to confirm the performance of the microRNA (miRNA) biomarker combination as a new breast cancer screening method in Korean women under the age of 50 with a high percentage of dense breasts. To determine the classification performance of a set of miRNA biomarkers (miR-1246, 202, 21, and 219B) useful for breast cancer screening, we determined whether there was a significant difference between the breast cancer and healthy control groups through box plots and the Mann– Whitney U-test, which was further examined in detail by age group. To verify the classification performance of the 4 miRNA biomarker set, 4 classification methods (logistic regression, random forest, XGBoost, and generalized linear model plus random forest) were applied, and 10-fold cross-validation was used as a validation method to improve performance stability. We confirmed that the best breast cancer detection performance was achievable in patients under 50 years of age when the set of 4 miRNAs were used. Under the age of 50, the 4 miRNA biomarkers showed the highest performance with a sensitivity of 85.29%, specificity of 93.33%, and area under the curve (AUC) of 0.961. Examining the results of 4 miRNA biomarkers was found to be an effective strategy for diagnosing breast cancer in Korean women under 50 years of age with dense breasts, and hence has the potential as a new breast cancer screening tool. Further validation in an appropriate screening population with large-scale clinical trials is required.

Relapsing polychondritis is a rare, multisystem autoimmune disease. It is characterized by recurrent inflammation of the cartilage and connective tissues in the body. In this paper, we described a case of relapsing polychondritis initially presented symptoms of cognitive dysfunction and personality changes. A 63-year-old male reprented fever, cognitive impairment and personality changes. Brain magnetic resonance imaging revealed leptomeningeal and periauricular hyperintensities. A cerebrospinal fluid examination showed aseptic meningitis. As he reprented hearing difficulties, audiometry showed the sensory neural hearing loss. On physical examination, erythematous swollen auricles were noted. Auricle biopsy consisted with inflammation with perichondritis. He was diagnosed with relapsing polychondritis accompanied by leptomeningeal meningitis, and treated with methylprednisolone (62.5 mg/day for 3 days) followed by prednisolone 60 mg/day and methotrexate 7.5 mg/week. Fever and painful swellings on the both ears subsided. He showed improvement in cognitive function and personality. Although relapsing polychondritis is rare, it should be considered to be a possible cause of leptomeningeal meningitis.

This study examined how achievement of session goals contributes to outcomes of subjects after participation in a 12-week lifestyle intervention program in men with metabolic syndrome (MetS). Thirty office workers with MetS, aged 47.2 +/- 6.6 years, participated in this study, from March to July, 2011. The intervention program included face-to-face counseling five times during the 12-week period. Counselors and subjects designed session goals for each round. The average of the goal achievement rate was calculated based on compliance for each round. The subjects were divided into three groups according to their tertiles of achievement rate: Low-compliance group (LC, < 59%), medium-compliance group (MC, 59-70%), and high-compliance group (HC, > 70%). Anthropometry, biochemical index, and nutrient intake were examined at baseline and at the end of the 12-week intervention program. After the intervention, diastolic blood pressure (DBP) showed a significant decrease in the LC group, and waist circumference (WC) showed a significant decrease in the MC group. Systolic blood pressure (SBP), DBP, and low-density lipoprotein cholesterol (LDL) showed a significant decrease in the HI group. Changes in SBP and DBP were significantly lower in the HC group than in the MC group (p < 0.05, p < 0.01). Changes in LDL were significantly lower in the HC group than in the MC group (p < 0.05). Results for intake of total energy, protein, fat, and sodium, as well as rates of carbohydrate and fat intake, showed a significant decrease in all participants (p < 0.05). The change in fiber was significantly higher in the HC group than in the MC group (p < 0.05). The change of fruit serving size showed a significant increase in the HC group (p < 0.01). The number of risk factors for MetS showed a significant decrease in the LC and HC groups (p < 0.05), however, no significant mean differences were observed among the three groups. In conclusion, participation in this intervention program resulted in positive effects on risk factors for MetS, nutrient intake, and dietary habits, especially in the High-compliance group.
