OBJECTIVE To analyze the features of non-mass-like (NML) breast lesions on ultrasound (US) and determine their corresponding malignancy rate and to stratify these lesion patterns according to US BI-RADS categories. MATERIALS AND METHODS One hundred sixty-four consecutive lesions were retrospectively classified into four types according to the US features,(More)
STUDY OBJECTIVES We compared the clinical characteristics and imaging findings between immunocompetent and immunocompromised patients in whom pulmonary cryptococcosis had been diagnosed to define the role of serum cryptococcal antigen (sCRAG) and radiographs during a follow-up period of up to 1 year. DESIGN Retrospective cohort study. SETTING University(More)
OBJECTIVE Aberrant expression of mismatch repair genes, such as human mutL homolog 1 (hMLH1) and human mutS homolog 2 (hMSH2), are common in some human cancers, and promoter methylation is believed to inactivate expression of hMLH1. We investigated whether promoter methylation is involved in loss of hMLH1 protein and whether aberrant expression of hMLH1 and(More)
Patterns of global histone modifications have been recently suggested as outcome predictors in cancer patients. To date, there has been no report on the prognostic significance of global histone modifications in esophageal squamous cell carcinoma. We investigated the role of global histone modification as outcome predictor in patients undergoing(More)
PURPOSE The purpose of this study was to determine the contribution of multidetector-row computed tomography (MDCT) in the management of adhesion-related small bowel obstruction (SBO) and to identify its predictive value for surgery. METHODS We conducted a retrospective review of 151 patients over a 5-year period with the diagnosis of SBO caused by(More)
This study aims to examine trends in outpatient psychotropic drug use among people with intellectual disabilities in Taiwan. The NHI outpatient medication records between January 1, 1997 and December 31, 2007 for people with intellectual disabilities were analyzed to observe the percent change, prevalence and prescription trends in psychotropic drugs. The(More)
BACKGROUND Promoter methylation inactivates expression of some important tumor suppressor genes and may be associated with histone modification. The fragile histidine triad (FHIT) gene is considered a tumor suppressor gene in different human epithelial cancers. We investigated whether FHIT methylation is associated with aberrant expression of Fhit protein(More)
Shorter sleep time was reported to be associated with psychological functioning in children. We intended to examine the relationship between nocturnal sleep duration and depression status by investigating if delayed bedtime could be one of the enhancement factors for depression in children. A cross-sectional study was performed to investigate the depression(More)
PURPOSE To determine the rate of underestimation of ductal carcinoma in situ (DCIS) diagnosed at imaging-guided biopsy and to analyze its association with HER2/neu oncogene, an important biomarker in assessing the tumour aggressiveness and guiding hormone therapy for breast cancer. METHODS We retrospectively reviewed 162 patients with DCIS diagnosed by(More)
This study aims to analyze the ambulatory visit frequency and medical expenditures of the general elderly population versus the elderly with intellectual disabilities in Taiwan, while examining the effects of age, gender, urbanization and copayment status on ambulatory utilization. A cross-sectional study was conducted to analyze data from 103,183 national(More)
