OBJECTIVE: Severity of nausea and vomiting of pregnancy (NVP) is associated with adverse pregnancy outcomes and poorer quality of life (QOL). The aim of this study was to evaluate the severity of NVP and maternal well-being status using the Pregnancy-Unique Quantification of Emesis and Nausea (PUQE) scale in a Korean population. METHODS: A total of 527 pregnant women who were receiving prenatal care at 4 hospitals were asked to participate in the study between January 2015 and June 2015. The severity of NVP was evaluated by the PUQE scale and maternal well-being status was evaluated using the visual analogue scale (VAS). Statistical analyses were performed to determine the risk factors associated with NVP and the associations between the severity of NVP and QOL. RESULTS: Among the 472 eligible pregnant women, 381 (80.7%) were suffering from NVP during pregnancy. No significant differences (P>0.05) were observed in any of the variables between the 2 study groups, with the exception of smoking, alcohol consumption, and history of NVP. NVP history was found to be the most powerful risk factor (adjusted odds ratio, 11.6; 95% confidence interval, 4.7–28.7). The correlation coefficient (r) between the VAS scores of maternal well-being status and PUQE severity was −0.25 (r 2=0.062; P-< 0.001). CONCLUSION: In this study, an explicit decline in maternal well-being status was observed according to severity of NVP. The PUQE scale may be of help to clinicians, healthcare providers, and researchers because of its simplicity and usefulness as a tool for NVP evaluation.

PURPOSE: Brain metastasis is estimated to occur in 20 to 40% of cancer patients, and meningeal involvement has been reported in 5% to 8% of cancer patients. Even if the prognosis is grave, standard treatment modality of brain metastasis or leptomeningeal carcinomatosis has not been established. We evaluated the prognosis and the clinical features of the brain and leptomeningeal metastasis of the breast cancer. MATERIALS AND METHODS: The 43 patients who was diagnosed as brain parenchymal metastasis or leptomeningeal carcinomatosis clinically, radiologically and/or cytologically were included in this study. The median age was 44(range: 27-61) years. RESULTS: The median duration from brain metastasis to death was 181 days(range: 8~1599), and the median duration from leptomeningeal carcinomatosis to death was 39 days(range: 25~152). Age(p=0.7174) and number of brain metastatic lesion(p=0.4097) did not influence the survival, but the presence of other systemic metastatic lesion affected the survival(p 0.0224). When we compared the survival rates of patients according to treatment modality, the patients with systemic chemotherapy versus patients without systemic chemotherapy showed differences(p= 0.0009). Patients treated with whole brain radiation only versus patients with whole brain radiation and other systemic management also showed different survival rate(p=0.0009). But intrathecal chemotherapy had no effect on survival. Well differentiated, solitary lesions were treated by operation and/or gamma-knife surgery, and their effects were good. CONCLUSION: Prolongation of survival was suggested with whole brain radiotherapy combined with systemic treatment in brain or leptomeningeal metastasis. Further study is expected to confirm this finding.

BACKGROUND: Expression of hepatic cholesterol 7alpha-hydroxylase (CYP7A1) is negatively regulated by orphan nuclear receptor small heterodimer partner (SHP). In this study, we aimed to find whether thyroid hormone regulates SHP expression by modulating the transcriptional activities of liver receptor homolog-1 (LRH-1). METHODS: We injected thyroid hormone (triiodothyronine, T3) to C57BL/6J wild type. RNA was isolated from mouse liver and used for microarray analysis and quantitative real-time polymerase chain reaction (PCR). Human hepatoma cell and primary hepatocytes from mouse liver were used to confirm the effect of T3 in vitro. Promoter assay and electrophoretic mobility-shift assay (EMSA) were also performed using human hepatoma cell line RESULTS: Initial microarray results indicated that SHP expression is markedly decreased in livers of T3 treated mice. We confirmed that T3 repressed SHP expression in the liver of mice as well as in mouse primary hepatocytes and human hepatoma cells by real-time PCR analysis. LRH-1 increased the promoter activity of SHP; however, this increased activity was markedly decreased after thyroid hormone receptor beta/retinoid X receptor alpha/T3 administration. EMSA revealed that T3 inhibits specific LRH-1 DNA binding. CONCLUSION: We found that thyroid hormone regulates the expression of SHP mRNA through interference with the transcription factor, LRH-1.

Although reports of multiple primary malignant tumors have increased recently, cases of synchronous double primary tumors of lung and liver are rare. A 73-year-old man suffered from chronic cough. His chest x-ray showed segmental atelectasis of the right upper lobe. Bronchoscopy revealed a mass occluding the orifice of the anterior segmental bronchus of the right upper lobe, and a biopsy showed a squamous cell carcinoma. A synchronous hepatic mass was found by ultrasonography. However, F18-FDG-PET showed no evidence of a distant metastasis. The liver biopsy revealed a hepatocellular carcinoma. A right upper lobe lobectomy and a sleeve resection were performed for the lung cancer, and radiofrequency ablation was performed for the hepatocellular carcinoma.

PURPOSE: We investigated whether irinotecan plus capecitabine improved progression-free survival (PFS) compared with capecitabine alone in patients with human epidermal growth factor 2 (HER2) negative and anthracycline and taxane pretreated metastatic breast cancer (MBC). MATERIALS AND METHODS: A total of 221 patients were randomly assigned to irinotecan (80 mg/m2, days 1 and 8) and capecitabine (1,000 mg/m2 twice a day, days 1-14) or capecitabine alone (1,250 mg/m2 twice a day, days 1-14) every 3 weeks. The primary endpoint was PFS. RESULTS: There was no significant difference in PFS between the combination and monotherapy arm (median, 6.4 months vs. 4.7 months; hazard ratio [HR], 0.84; 95% confidence interval [CI], 0.63 to 1.11; p=0.84). In patients with triple-negative breast cancer (TNBC, n=90), the combination significantly improved PFS (median, 4.7 months vs. 2.5 months; HR, 0.58; 95% CI, 0.37 to 0.91; p=0.02). Objective response rate was numerically higher in the combination arm, though it failed to reach statistical significance (44.4% vs. 33.3%, p=0.30). Overall survival did not differ between arms (median, 20.4 months vs. 24.0 months; p=0.63). While grade 3 or 4 neutropenia was more common in the combination arm (39.6% vs. 9.0%), hand-foot syndrome was more often observed in capecitabine arm. Quality of life measurements in global health status was similar. However, patients in the combination arm showed significantly worse symptom scales especially in nausea/vomiting and diarrhea. CONCLUSION: Irinotecan plus capecitabine did not prove clinically superior to single-agent capecitabine in anthracycline- and taxane-pretreated HER2 negative MBC patients. Toxicity profiles of the two groups differed but were manageable. The role of added irinotecan in patients with TNBC remains to be elucidated.

BACKGROUND/AIMS: Despite of increasing numbers of reports on intraductal papillary mucinous tumor (IPMT), there is still difficulty in its' diagnosis, treatment and prediction of prognosis. The purpose of this multicenter study was to evaluate the clinico-pathological features of IPMT in Korea and suggest the prediction criteria of malignancy in IPMT. METHODS: We retrospectively reviewed the clinico-pathological data of 208 patients who underwent operations with IPMT between 1993 and 2002 at 28 institutes in Korea. RESULTS: Of the 208 patients with a mean age of 60.5+/-9.7 years, 147 were men and 61 were women. 124 patients underwent pancreatoduodenectomy, 42 distal pancreatectomy, 17 total pancreatectomy, 25 limited pancreas resection. Benign cases were 128 (adenoma (n=62), borderline (n=66)) and malignant cases were 80 (non-invasive (n=29), invasive (n=51)). A significant difference in 5-year survival was observed between benign and malignant group (92.6% vs. 65.3%; p=0.006). Of the 6 factors (age, location, duct dilatation, tumor appearance, main duct type, and tumor size) that showed the statistical difference in univariate analysis between benign and malignant group, we found three significant factors (tumor appearance (p=0.009), tumor size (p=0.023), and dilated duct size (p=0.010)) by multivariate analysis. CONCLUSION: Although overall prognosis of IPMT is superior to ordinary pancreatic cancer, more curative surgery is recommended in malignant IPMT. Tumor appearance (papillary), tumor size (> or =30 mm) and dilated duct size (> or = 12 mm) can be used as preoperative indicators of malig-nancy in IPMT.

PURPOSE: This study was performed in order to determine the changes over time in preventable and potentially preventable traumatic death rates, and to assess the factors that affected the deaths of trauma patients which occurred in Korean pre-hospital and hospital settings. METHODS: All trauma deaths occurring either in the emergency department (ED) or after admission at twenty Korean hospitals between August 2009 and July 2010 were retrospectively analyzed. The deaths were initially reviewed by a team of multidisciplinary specialists and classified into non-preventable, potentially preventable, and preventable deaths. Only preventable and potentially preventable deaths were the subject of our analysis. Structured data extraction included patient demographics, vital signs, injury severity, probability of survival, preventability of mortality, reported errors in the evaluation and management of the patient, and classification of error types (system, judgment, knowledge). RESULTS: During the study period, 446 trauma victims died in the ED or within 7 days after admission. The mean age was 52 years, 74.1% were men and the mean time from injury to death was 35.6 hours. The most common cause of death was head injury (44.7%) followed by hemorrhage (30.8%) and multi-organ failure (8.0%). The rates of preventable/potentially preventable deaths were 35.2% overall and 29.8% when limited to patients surviving to admission. Of all death classifications, 31.2% were potentially preventable and 4.0% were preventable. Errors leading to preventable death occurred in the emergency department (51.2%), pre-hospital setting (30.3%) and during inter-hospital transfer (60.8%). Most errors were related to clinical management (48.4%) and structural problems in the emergency medical system (36.5%). CONCLUSION: The preventable death rates for Korean trauma victims were higher than those found in other developed countries, possibly due to poorly established emergency medical systems for trauma victims in pre-hospital and hospital settings. A system wide approach based on the emergency medical system and well-developed in-hospital trauma teams should be adopted in order to improve the quality of care of trauma victims in Korea.
