Colorectal cancer (CRC) is the most common tumour type in both sexes combined in Western countries. Although screening programmes including the implementation of faecal occult blood test and colonoscopy might be able to reduce mortality by removing precursor lesions and by making diagnosis at an earlier stage, the burden of disease and mortality is still(More)
Serotypes and antibiotic sensitivities were determined for 338 strains of Streptococcus pneumoniae from children of north-western Greece with invasive pneumococcal disease (IPD), acute otitis media (AOM) and nasopharyngeal carriage. The most common serotypes among the isolates from IPD were 14 and 19F, while 3, 19F, 9V and 14 were the major cause of AOM. In(More)
Web educational resources integrating interactive simulation tools provide students with an in-depth understanding of the medical imaging process. The aim of this work was the development of a purely Web-based, open access, interactive application, as an ancillary learning tool in graduate and postgraduate medical imaging education, including a systematic(More)
This paper describes the k-means range algorithm, a combination of the partitional k-means clustering algorithm with a well known spatial data structure, namely the range tree, which allows fast range searches. It offers a real-time solution for the development of distributed interactive decision aids in e-commerce since it allows the consumer to model his(More)
The quality of guidelines is often modest and highly variable. We searched the Medline database for occupational asthma (OA) guidelines meeting our inclusion criteria and undertook a systematic appraisal of them. Six appraisers independently evaluated these guidelines using the AGREE II (Appraisal of Guidelines, Research and Evaluation II) instrument.(More)
OBJECTIVE To investigate a necrotizing enterocolitis (NEC) cluster of late preterm and term neonates (gestational age ≥34 weeks). METHODS We conducted a descriptive and a case-control study. Medical records of neonates with modified Bell stage ≥ IB NEC and matched controls were reviewed, in addition to microbiological and environmental investigation.(More)
OBJECTIVE To present a case of brucellosis-induced severe autoimmune hemolytic anemia (AIHA) that was refractory to traditional corticosteroid treatment and eventually treated with rituximab apart from antibiotic therapy and to discuss the potential role of rituximab in similar cases of AIHA triggered by an underlying reversible cause. CASE SUMMARY A(More)
The problem of approximate string matching is important in many different areas such as computational biology, text processing and pattern recognition. A great effort has been made to design efficient algorithms addressing several variants of the problem, including comparison of two strings, approximate pattern identification in a string or calculation of(More)
This paper presents a personalized approach for distributed trust management by employing the k-means range algorithm, a combination of the partitional kmeans clustering algorithm with orthogonal range search concepts. The aim of this approach is to aid the human or computer agent in organizing information from multiple sources into clusters according to(More)
