Sleep stage classification is one of the most critical steps in effective diagnosis and the treatment of sleep-related disorders. Visual inspection undertaken by sleep experts is a time-consuming and burdensome task. A computer-assisted sleep stage classification system is thus essential for both sleep-related disorders diagnosis and sleep monitoring. In this paper, we propose a system to classify the wake and sleep stages with high rates of sensitivity and specificity. The EEG signals of 25 subjects with suspected sleep-disordered breathing, and the EEG signals of 20 healthy subjects from three data sets are used...

Vascular structures of skin are important biomarkers in diagnosis and assessment of cutaneous conditions. Presence and distribution of lesional vessels are associated with specific abnormalities. Therefore, detection and localization of cutaneous vessels provide critical information towards diagnosis and stage status of diseases. However, cutaneous vessels are highly variable in shape, size, color and architecture, which complicate the detection task. Considering the large variability of these structures, conventional vessel detection techniques lack the generalizability to detect different vessel types and require separate algorithms to be designed for each type...

Small intestinal tumors are rare with adenocarcinoma of the small intestine accounting for less than 2% of all gastrointestinal cancers. Primary jejunal adenocarcinoma constitutes a minute portion of small intestine adenocarcinomas. Clinically, this cancer presents at latter stages of its progression, mainly due to vague and non-specific symptoms, and the difficulty encountered in accessing the jejunum on upper endoscopy. Diagnosis of jejunal adenocarcinoma is usually inconclusive with the use of computed tomography (CT) scan, small bowel series, or upper endoscopy...

A 57-year-old woman visited our hospital with left chest pain. Chest computed tomography (CT) scanning showed left pneumothorax with apical bullae and a nodular shadow in the left anterior mediastinum accidentally. However, a week later, we could not detect a mediastinal shadow on chest CT image after healing of left pneumothorax. Video assisted thoracoscopic surgery was scheduled in order to remove bullae and evaluate an anterior mediastinal lesion. The mediastinal lesion was tumorous and resected with around pericardial fat tissue...

PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) is a well established risk factor for lung cancer. Newer studies reveal a myriad of other mechanisms, some proven and some putative, which may contribute to their association. RECENT FINDINGS: There is an ever-growing bundle of evidence that suggests a close association between persistent chronic inflammation and lung cancer. A few potential targets of genetic susceptibility locus for COPD and lung cancer have been suggested...

Algorithmic segmentation of histologically relevant regions of tissues in digitized histopathological images is a critical step towards computer-assisted diagnosis and analysis. For example, automatic identification of epithelial and stromal tissues in images is important for spatial localisation and guidance in the analysis and characterisation of tumour micro-environment. Current segmentation approaches are based on supervised methods, which require extensive training data from high quality, manually annotated images...
