Peripheral Nerve Stimulation Implantation Combining Ultrasound With Microendoscopy for Management of Chronic Neuropathic Pain: A Case Series Study.

Background: Peripheral nerve stimulation (PNS) has emerged as a minimally invasive percutaneous procedure addressing neuropathic pain. However, the percutaneous cylindrical lead ultrasound-guided implantation procedure requires expertise that limits widespread PNS utilization. To overcome these challenges, a microinvasive endoscopy device has very recently been developed, enhancing the precision of PNS implantation by providing accurate visualization of the targeted nerve.

Lumbosacral plexus and pudendal nerve magnetic resonance tractography: A systematic review of the clinical applications for pudendal neuralgia.

Diffusion tensor imaging (DTI) is commonly used to establish three-dimensional mapping of white-matter bundles in the supraspinal central nervous system. DTI has also been the subject of many studies on cranial and peripheral nerves. This non-invasive imaging technique enables virtual dissection of nerves in vivo and provides specific measurements of microstructural integrity.

How to Do It: Microsurgical DREZotomy for Pain After Brachial Plexus Injury: 2-Dimensional Operative Video.

More than three-quarters of victims of brachial plexus injury suffer from refractory neuropathic pain.1-6 Main putative mechanism is paroxysmal hyperactivity in the dorsal horn neurons at the dorsal root entry zone (DREZ) as demonstrated by microelectrode recordings in animal models7 and patients.8 Pain relief can be achieved by lesioning the responsible neurons in the spinal cord segments with avulsed rootlets.

[Antibodies against hepatitis B virus core antigen among blood donors].

The prevalence of antibodies to the hepatitis B virus (HBV) core antigen (anti-HBc) and the risk factors are evaluated in different blood donor groups. In 1998, on 12,456 first donations, 163 (1.31%) were positive with the two anti-HBc screening tests.
