    Granular cell tumours (GCT) of the soft tissues are rare benign tumours but some time may be difficult to distinguish from malignant neoplasms. It is important that clinicians are aware of their existence. We present a new case of GCT of the soft tissues followed by a brief review of literature

    Enabling the use of a planning agent for urban traffic management via enriched and integrated urban data

    Improving a city’s infrastructure is seen as a crucial part of its sustainability, leading to efficiencies and opportunities driven by technology integration. One significant step is to support the integration and enrichment of a broad variety of data, often using state of the art linked data approaches. Among the many advantages of such enrichment is that this may enable the use of intelligent processes to autonomously manage urban facilities such as traffic signal controls. In this paper we document an attempt to integrate sets of sensor and historical data using a data hub and a set of ontologies for the data. We argue that access to such high level integrated data sources leads to the enhancement of the capabilities of an urban transport operator. We demonstrate this by documenting the development of a planning agent which uses such data as inputs in the form of logic statements, and when given traffic goals to achieve, outputs complex traffic signal strategies which help transport operators deal with exceptional events such as road closures or road traffic saturation. The aim is to create an autonomous agent which reacts to commands from transport operators in the face of exceptional events involving saturated roads, and creates, executes and monitors plans to deal with the effects of such events. We evaluate the intelligent agent in a region of a large urban area, under the direction of urban transport operators

    Sialoblastoma- long-term follow-up and remission for a rare salivary malignancy

    Get PDF
    Sialoblastoma is a rare salivary neoplasm which presents either congenitally or during early infancy. It was originally considered a benign neoplasm, however a number of reported cases have documented locoregional recurrence and distant metastases. Currently, there is no consensus on the appropriate treatment for this neoplasm. We report on long term follow-up of a patient with metastatic sialoblastoma, and a brief discussion of the possible treatment modalities currently being considered

    An unusual cause of haemoptysis in a young male

    Inflammatory myofibroblastic tumours are reported to occur in a variety of sites, including the head and neck, abdominal organs, central nervous system and urinary tract. They only rarely occur in the lung. We report a case of a 25-year-old male admitted with haemoptysis. His chest radiograph showed a peripheral right lung opacity and computed tomography revealed a right lower lobe soft tissue density mass. Bronchoscopy and fine needle aspiration were unhelpful. a diagnosis of pulmonary carcinoma was made, and the patient underwent a right lower lobectomy. On pathology, the tumor was found to be an inflammatory pseudotumor. These lesion are extremely rare, constituting less than 1% of pulmonary malignancies, but are known to occur in young patients. We believe clinicians need to retain an index of suspicion for the presence of this disease in young patients, which can masquerade as more common malignancies
