The aim of the study was to investigate the novel endoscopic findings in nasopharyngeal carcinoma (NPC) under narrow-band imaging (NBI) and to determine the reliability of screening NPC by NBI. A total of 79 adults underwent nasopharyngeal biopsy. We proposed five distinctly different findings that need to be examined by NBI: Type I: brownish spots, Type(More)
PURPOSE To determine the changes of magnetic resonance imaging (MRI) during the periictal phase in status epilepticus (SE). PATIENTS AND METHODS We identified 15 patients diagnosed of status epilepticus with corresponding MRI changes, including 11 patients with generalized convulsive status epilepticus (GCSE), 2 with complex partial status epilepticus(More)
PURPOSE Transitional cell carcinoma is the most common upper urinary tract cancer in Taiwanese patients on dialysis. It is a unique finding compared with Western countries. Unfortunately, the long-term outcomes of patients with upper urinary tract transitional cell carcinoma on dialysis are largely unknown. This study presents clinical outcome of patients(More)
BACKGROUND AND PURPOSE Accurate information about hospital resource utilization is necessary for management of healthcare service. The purpose of this study was to determine the demographic and clinical predictors of length of hospital stay (LOS) of acute care hospitalization for first-ever ischemic stroke patients. METHODS A group of 330 patients who(More)
The aim of this study was to identify the risk factors associated with bone grafts infection after cranioplasty. Eighty-four cranioplasties were performed on 75 patients between 2002 and 2006. Cryopreserved bone grafts were used as graft material in group 1 and polymethylmethacrylate (PMMA) was used in group 2. Risk factors including age, gender, time(More)
To investigate the relationship between traffic air pollution exposure and development of childhood leukemia (14 yr of age or younger), a matched case-control study was conducted using childhood deaths that occurred in Taiwan from 1996 through 2006. Data on all eligible childhood leukemia deaths were obtained from the Bureau of Vital Statistics of the(More)
BACKGROUND The purpose of this study was to show the investigated prevalence rate of brownish spots of early cancer under narrow band imaging (NBI) in different sites/types of the epithelium. METHODS In all, 125 adults with early mucosal cancer underwent NBI examination. Four types of epithelium were categorized: keratinized thick stratified squamous(More)
BACKGROUND The aim of this study was to evaluate whether arterial spin labeling (ASL) perfusion magnetic resonance imaging (MRI) can reliably quantify perfusion deficit as compared to dynamic susceptibility contrast (DSC) perfusion MRI. METHODS Thirty-nine patients with acute ischemic stroke in the anterior circulation territory were recruited. All(More)
AIM To analyze the risk factors for central port failure in cancer patients administered chemotherapy, using univariate and multivariate analyses. METHODS A total of 1348 totally implantable venous access devices (TIVADs) were implanted into 1280 cancer patients in this cohort study. A Cox proportional hazard model was applied to analyze risk factors for(More)
BACKGROUND Necrotizing fasciitis is an uncommon and life-threatening soft tissue infection with high mortality. Though early aggressive surgical intervention is important for improving survival, the impact of mortality from different microorganisms remains uncertain. Our study aims to identify the association of mortality and different microorganisms, and(More)
