We present three cases of desmoplastic infantile ganglioglioma in patients admitted to our institution in the past 8 years. CT and MR findings are discussed. Typically, these lesions are located in the frontal and parietal lobes, appearing as cystic tumors with a solid cortical component within the cerebrum, which enhances intensely, and moderate… (More)
BACKGROUND Childhood asthma is characterized by inflammation of the airways. Structural changes of the airway wall may also be seen in some children early in the course of the disease. Matrix metalloproteinases (MMPs) are key mediators in the metabolism of the extracellular matrix (ECM). OBJECTIVE To investigate the balance of MMP-8, MMP-9 and tissue… (More)
Airway inflammation in children can be assessed by nonbronchoscopic bronchoalveolar lavage (BAL). Little is known about the repeatability of cell counts in the BAL obtained. Children (n=43) attending for elective surgery were studied. Cell counts were obtained following a nonbronchoscopic lavage. Two samples were obtained with either: 1) the catheter wedged… (More)
In this paper, a vision-based real-time traffic analysis system is presented, which can analyze vehicles in traffic from a traffic video sequence. This paper discusses object detection, and tracking of objects in multiple video frames. The functionalities of traffic analysis using computer vision include vehicle speed estimation, traffic flow direction… (More)
This paper involves object detection, object tracking and classification of objects, and indexing from vehicle surveillance videos automatically. The objects are detected using optical flow method and tracked using Kalman Filtering method. The objects extracted are classified using ten features including shape based features such as area, height, width,… (More)
Primary malignant fibrous histiocytomas are rare. The authors report on a 56-year-old man who presented with neurological symptoms due to cerebral metastasis of a primary malignant fibrous histiocytoma of the lung.
Over a 12-year period, the authors encountered 2 patients with spinal axis/basimeningeal primitive neuroectodermal tumor (PNET) involving the spinal axis extramedullary, intradural compartment and the basimeninges. In neither patient was an intraaxial focus demonstrated. A 48-year-old woman had computed tomography (CT) findings of hydrocephalus and later… (More)
