A Pure Epidural Spinal Cavernous Hemangioma — With an Innocuous Face But A Perilous Behaviour!! [PDF]
Journal of Clinical and Diagnostic Research, 2013 Cavernous hemangiomas occur frequently in the intracranial structures but they are rare in the spine, with an incidence of 0.22 cases/million/year, which account for 5 – 12% of the spinal vascular lesions, 51% of which are extradural.

Needle guidance with Doppler-tracked polarization-sensitive optical coherence tomography [PDF]
arXiv, 2023 We demonstrate that a simple, unscanned polarization-sensitive optical coherence tomography needle probe can be used to perform layer identification in biological tissues. Broadband light from a laser centered at 1310 nm was sent through a fiber that was embedded into a needle, and analysis of the polarization state of the returning light after ...

Epidural vascular malformation demonstrated by epidural venography [PDF]
American Journal of Roentgenology, 1979 A previously healthy 11-year-old boy complained of 3 days of discomfort in the left lumbar region, left buttock, and posterior thigh. He had had an upper respiratory infection forthe previous 2 weeks and had been fallen on by another player, without apparent injury, during a hockey game on the day pain began.

Epidural pump implantation in refractory pain in pancreatic carcinoma
Indian Journal of Pain, 2021 Reported is a case of an epidural pump implantation done in a patient with refractory pancreatic cancer pain. The patient was earlier given celiac and splanchnic nerve block and later an epidural pump was implanted when the total oral morphine dose ...

Nonlinear brain dynamics as macroscopic manifestation of underlying many-body field dynamics [PDF]
Physics of Life Reviews 3, 93-118 (2006), 2005 Neural activity patterns related to behavior occur at many scales in time and space from the atomic and molecular to the whole brain. Here we explore the feasibility of interpreting neurophysiological data in the context of many-body physics by using tools that physicists have devised to analyze comparable hierarchies in other fields of science.

An adaptive closed-loop ECoG decoder for long-term and stable bimanual control of an exoskeleton by a tetraplegic [PDF]
arXiv, 2022 Brain-computer interfaces (BCIs) still face many challenges to step out of laboratories to be used in real-life applications. A key one persists in the high performance control of diverse effectors for complex tasks, using chronic and safe recorders. This control must be robust over time and of high decoding performance without continuous recalibration

British Journal of Anaesthesia, 2006 Until recently epidural abscess was considered a rare, almost theoretical, complication of central nerve block, but anecdotal reports suggest that this is no longer the case. Thus a review of the risk factors, pathogenesis, clinical features and outcome of this condition is appropriate, the primary aim being to make recommendations on best anaesthetic ...
