Subdural hematoma (SDH) has been reported in 0.5-4% of all intracranial metastatic tumors. Chronic SDH has been reported in intracranial metastases from both solid and haematological malignancies. Here we report recurrent SDH in a patient with chronic myeloid leukaemia (CML) following dural metastases. An elderly male patient a known case of(More)
The design of efficient routing protocols is a fundamental problem in a Mobile Ad-Hoc Network (MANET). Many different protocols have been proposed in the literature, each one based on different characteristics and properties. Some of these protocols have been studied and their performances have been evaluated in detail focusing on aspects like routing(More)

After Patient's ophthalmologic, neurosurgery evaluation was diagnosed to have Tuberculum sellae meningioma which caused vision loss. After surgery, patient's best(More)
Mobile Ad Hoc Networks (MANETs) are multihop wireless networks in which all nodes cooperatively maintain network connectivity. In such a multihop wireless network, every node may be required to perform routing in order to achieve end to end communication among nodes. These networks are energy constrained as most ad hoc mobile nodes today operate with(More)
