Stereotactic radiosurgery is being increasingly advocated as the primary modality for treatment of vestibular schwannomas (VS). This modality has been shown to arrest tumor growth, with few associated short-term morbidities, and with possibly better hearing and facial nerve preservation rates than microsurgery. Radiation-induced oncogenesis has long been(More)
Radiotherapy-induced nausea and vomiting (RINV) are common and troublesome symptoms experienced by patients undergoing radiotherapy. Although quality of life and symptom control now figure prominently in evaluations of cancer therapies, progress in RINV research and clinical prevention has been slow. This article summarizes the major guidelines for the(More)
OBJECTIVE To report the clinical spectrum seen in young abusers of street-ketamine (regular recreational abusers of street-ketamine, for its hallucinogenic effects) in Hong Kong, presenting with significant lower urinary tract symptoms (LUTS) but with no evidence of bacterial infection. PATIENTS AND METHODS We retrospectively analysed the clinical(More)
PURPOSE Dosimetric data are reported for five cases of radiation-induced myelopathy after stereotactic body radiotherapy (SBRT) to spinal tumors. Analysis per the biologically effective dose (BED) model was performed. METHODS AND MATERIALS Five patients with radiation myelopathy were compared to a subset of 19 patients with no radiation myelopathy(More)
PURPOSE To describe and assess an interdisciplinary research training program for graduate students, postdoctoral fellows, and clinical fellows focused on radiation medicine; funded by the Canadian Institutes for Health Research since 2003, the program entitled "Excellence in Radiation Research for the 21st Century" (EIRR21) aims to train the next(More)
PURPOSE To document the incidence and timing of radiotherapy-induced nausea and vomiting (RINV) in the treatment of bone metastases among patients receiving prophylaxis with a 5-HT(3) receptor antagonist. METHODS Patients receiving single (SF) or multiple fraction (MF) palliative radiotherapy (RT) of moderate or low emetogenic risk for bone metastases(More)
It is well established that cigarette smoking is hazardous to health and is a risk factor for many chronic diseases. However, its impact on the brain, whether it be from prenatal exposure to maternal cigarette smoking, cerebrovascular disease, Alzheimer's disease (AD) or Parkinson's disease, is still not very clear. Neuroimaging and neuropathological(More)
PURPOSE Radiation induced peripheral nerve tumors (PNT) are a rare but known complication of radiotherapy. The clinical and pathologic features of six cases of post-radiation PNT's are reported here, more than doubling the number of known cases reported in the literature. METHODS We reviewed six cases of radiation induced PNT and performed a review of the(More)
Without their cooperation, this project could not have been successfully completed and accomplished in a timely fashion. Academic libraries must demonstrate empirically that library usage does contribute positively to student academic performance and, thereby, to the university's effectiveness. While customary academic library assessment practices may not(More)
Colorectal small cell carcinoma (SmCC) is a rare tumor with an aggressive course. The aim of this study is to summarize our experience with this tumor and to highlight its immunohistochemical profile. Ten cases of colorectal SmCC were identified in our files and a panel of immunostains was performed. Follow up was available for the average of 3 years,(More)
