Abbreviations are common in biomedical documents and many are ambiguous in the sense that they have several potential expansions. Identifying the correct expansion is necessary for language understanding and important for applications such as document retrieval. Identifying the correct expansion can be viewed as a Word Sense Disambiguation (WSD) problem. A(More)
To determine whether the method of bladder cuff excision (BCE) during laparoscopic radical nephroureterectomy for upper urinary tract urothelial carcinoma is associated with rates of disease recurrence or metastases. We performed a retrospective review of all laparoscopic radical nephroureterectomies performed at our institution over 10 years. Three methods(More)
To date, the "monorail snare technique" for the retrieval of entombed microcatheter tips during OnyxTM (ev3, Irvine, CA) embolisation of brain arteriovenous malformations (BAVM) has not been described. We report our experiences and some technical aspects in using this technique for the retrieval of entombed MarathonTM microcatheter (ev3, Plymouth, MN) tips(More)
Introduction. ADT is used in the management of locally advanced and metastatic disease. The detrimental effect of ADT on bone density is well documented. This study assesses care gaps in screening, prevention and treatment of osteoporosis among prostate cancer patients. Methods. We conducted a retrospective cohort study for patients diagnosed with(More)
INTRODUCTON Radical nephroureterectomy for upper tract urothelial carcinoma (UTUC) must include some form of distal ureter management to avoid high rates of tumour recurrence. It is uncertain which distal ureter management technique has the best oncologic outcomes. To determine which distal ureter management technique resulted in the lowest tumour(More)
BACKGROUND Research literature in biomedicine and related fields contains a huge number of claims, such as the effectiveness of treatments. These claims are not always consistent and may even contradict each other. Being able to identify contradictory claims is important for those who rely on the biomedical literature. Automated methods to identify and(More)
Given a set of abstracts retrieved from a search engine such as Pubmed, we aim to automatically identify the claim zone in each abstract and then select the best sen-tence(s) from that zone that can serve as an answer to a given query. The system can provide a fast access mechanism to the most informative sentence(s) in abstracts with respect to the given(More)
Endometriosis is a common gynecological condition, but involvement of the urinary tract is rare. Ureteral endometriosis can present in a nonspecific fashion, and may mimic ureteral malignancy. This case report describes a 44-year-old woman who initially presented with chronic flank pain and was found to have left-sided renal dysfunction and a distal left(More)
