BACKGROUND War wounds produce a significant burden on medical facilities in wartime. Workload from the recent conflict was documented in order to guide future medical needs. METHODS All data on war injuries were collected prospectively. This information was supplemented with a review of all patients admitted during the study period. RESULTS During the(More)
We report on the survival of 145 patients presenting to a single centre with a pathological metastatic fracture of the proximal femur. The single surviving patient had a follow-up of 17.7 years. Mean survival for the 144 patients who died was 332 days (range 2 to 3053 days), being longest for those with myeloma (662 days), lymphoma (> 633 days) and breast(More)
We have studied the placement of three screws within the femoral head and the degree of angulation of the screws in 395 patients with displaced intracapsular fracture of the hip to see if either was related to the risk of failure of the fracture to unite. No relationship between nonunion of the fracture was found regarding the position of the screws on the(More)
Web search engines discover indexable documents by recursively 'crawling' from a seed URL. Their rankings take into account link popularity. While this works well, it introduces biases towards older documents. Older documents are more likely to be the target of links, while new documents with few, or no, incoming links are unlikely to rank highly in search(More)
The Thomas splint was developed for the stabilisation of femoral fractures at the end of the nineteenth century, and since the First World War has been extensively used by the British Army. It has been shown to improve the outcome after ballistic fractures of the femur, but recently there have been moves to abandon this device in favour of more modern(More)
When a searcher submits a query Q and clicks on document R in the corresponding result set, we may plausibly interpret the click as a vote that Q is a description of R. We call the Q and R pairing a 'click description'. Click descriptions thus derived from search engine logs can be accumulated into surrogate documents and used to boost retrieval(More)
In real world use of test collection methods, it is essential that the query test set be representative of the work load expected in the actual application. Using a random sample of queries from a media company's query log as a 'gold standard' test set we demonstrate that biases in sitemap-derived and top <i>n</i> query sets can lead to significant(More)
Web pages contain both unique text, which we should include in indexes, and template text such as navigation strips and copyright notices which we may want to discard. While algorithms exist for removing template text, most rely on first completing a crawl and then parsing each page. We present a cheap and efficient algorithm which does not parse HTML and(More)
