introduction :  despite  recent  advances  in  treatment  of  oral  cancer,  it  still causes high rates of mortality and morbidity worldwide. delays in diagnosis and treatment of these cancers greatly affect the prognosis.  this study aimed to assess the treatment delay and its relation to diagnostic delay among oral cancer patients in tehran, iran. materials and methods : we studied 100 patie...

compared to western countries, pancreatic cancer has a relatively low incidence in iran. it is rarely diagnosed before the fifth decade in iran and most of the patients are older than 60 at the time of diagnosis like to the western countries, where pancreatic cancer is a disease of advanced age. the incidence of the disease in some young patients suggests a possible role of genetic defects, whi...

Introduction This study was conducted in Brazil and Colombia,where dengue is endemic and vector control programs use chemical insecticides. Methods We identified knowledge, attitudes, and practices about dengue and determined the infestation levels of Aedes aegypti in one Brazilian and four Colombian communities. Results The surveys show knowledge of the vector, but little knowledge about diagn...

Diagnosis and prognosis are necessary tasks for system reconfiguration and fault-adaptive control in complex systems. Diagnosis consists of detection, isolation and identification of faults, while prognosis consists of prediction of the remaining useful life of systems. This paper presents an integrated model-based distributed diagnosis and prognosis framework, where system decomposition is use...

Prognostics and health management (PHM) is an engineering approach dealing with the diagnosis, prognosis, of state systems. Methods that can analyze system behavior, fault conditions, degradation are crucial for PHM applications, as they create basis determining, predicting, monitoring Data-driven methods have been proven to be suitable automated diagnosis or prognosis due their pattern recogni...

Introduction: Extranodal Natural Killer (NK)/T-cell lymphoma (NKTCL) nasal type is a rare but well-known disease with poor prognosis. NKTCL is more prevalent in Asia and comprises about 7-10% of all non-Hodgkin lymphoma cases in this region. The characteristic clinical pattern of NKTCL is the destruction of the midline structures of the mid-face. Case Report: The present study examines a case o...

This paper argues that automated knowledge acquisition for diagnosis has had limited success in both failure-driven diagnosis and model-based diagnosis. The paper describes fault-based and model-based reasoning for diagnosis and surveys some of the approaches to knowledge acquisition in both areas. The Hakeem1 algorithm I am currently implementing for the automated generation of behavioural mod...

In this paper, we present an ongoing research effort on developing an automatic fault diagnosis and prognosis service for large-scale computing systems, such as TeraGrid clusters. By leveraging the research on system health monitoring, the proposed service aims at automatically revealing fault patterns from historical data by applying data mining and machine learning techniques. To address key ...

Acute-on-chronic mesenteric ischemia is rare, symptomatic manifestation of arteriosclerosis, and there are important gaps in our knowledge and recognition of this potentially lethal condition. Careful exploration of anamnestic history and angiography remain cornerstones of early diagnosis. Prognosis crucially depends on rapid diagnosis and surgical management, to prevent, or at least to minimiz...
