We report a patient with adenoid cystic carcinoma of the external auditory canal with multiple pulmonary, liver and renal secondaries. She had a palpable left renal mass. The clinical course and treatment of this unusual neoplasm as reported in literature are briefly reviewed.
A case of carcinoma of the lower alveolus metastasizing to the phalanges of the hand is reported. The possible mechanism of such metastases, the clinical and radiological features and the role of fine needle aspiration cytology are discussed.
The dynamic web has increased exponentially over the past few years with more than thousands of documents related to a subject available to the user now. Most of the web documents are unstructured and not in an organized manner and hence user facing more difficult to find relevant documents. A more useful and efficient mechanism is combining clustering with… (More)
Search engine returns thousands of web pages for a single user query, in which most of them are not relevant. In this context, effective information retrieval from the expanding web is a challenging task, in particular, if the query is ambiguous. The major question arises here is that how to get the relevant pages for an ambiguous query. We propose an… (More)
The Traditional apriori algorithm can be used for clustering the web documents based on the association technique of data mining. But this algorithm has several limitations due to repeated database scans and its weak association rule analysis. In modern world of large databases, efficiency of traditional apriori algorithm would reduce manifolds. In this… (More)
Basaloid squamous carcinoma is a rare variant of squamous carcinoma and is known for its aggressive behavior. Its presentation in the nasal cavity is uncommon . A case of this tumor arising from the nostril and showing good response to concomitant radiotherapy and cisplatinum is presented.
Exponential growth of the web increased the importance of web document classification and data mining. To get the exact information, in the form of knowing what classes a web document belongs to, is expensive. Automatic classification of web document is of great use to search engines which provides this information at a low cost. In this paper, we propose… (More)
The World Wide Web serves as a huge repository of information that is highly dynamic, diverse and growing at an exponential rate in a lightening speed. In order to speed-up and further improve tasks like information search and retrieval, personalization etc; it is highly important to develop techniques to classify text documents more accurately and… (More)
The size of web has increased exponentially over the past few years with thousands of documents related to a subject available to the user. With this much amount of information available, it is not possible to take the full advantage of the World Wide Web without having a proper framework to search through the available data. This requisite organization can… (More)
The aim of this study is to develop collimator inserts of various sizes which are either not commercially available or are expensive to import. The dosimetry parameters such as tissue maximum ratio (TMR), off-axis ratio (OAR) and output factor of the developed collimator insert are compared with that of the commercial collimator insert (Radionics). In order… (More)
