Article Abstract
The most frequently encountered complication of dorsal column stimulators is lead migration. The vast majority of these events are seen in the first few weeks to months. Late paddle lead migration is a very uncommon occurrence in this setting. We describe a case of a 51-year-old male with a history of reflex sympathetic dystrophy having undergone dorsal column stimulator insertion at the level of C1-C2. A good clinical benefit was appreciated in the postoperative period once the stimulator was turned on. Approximately six months postoperatively, the patient suddenly lost coverage. Radiographic imaging revealed that the lead had migrated caudally to the C3-C4 level. Subsequent revision surgery took place. This description highlights a common complication, but occurring outside the expected time frame after surgery.

Therapeutic role of Differential Target Multiplexed (DTM) spinal cord stimulation in painful diabetic neuropathy. Case report.

Diabetic peripheral polyneuropathy (DPN) is the most common cause for diabetic foot complications, including diabetic ulcers, Charcot arthropathy, and lower limb amputations. Spinal Cord Stimulation (SCS) is a safe and effective treatment used for pain reduction in neuropathic/nociceptive pain conditions; the most common stimulation modalities used for the management of painful diabetic neuropathy were conventional paresthesia-based and high-frequency SCS, which stimulate the A beta fibers in the dorsal column of the spinal cord. Differential Target Multiplexed (DTM) SCS is a novel paresthesia-free stimulation technique targeting the supportive glial cells in the nervous system, modulating glial cells and neurons with a rebalance of their interactions.

Skilled forelimb patterning is regulated by the corticospinal tract (CST) with support from brainstem regions. When the CST is lesioned, there is a loss of forelimb function; however, if indirect pathways remain intact, rehabilitative training can facilitate recovery. Following spinal cord injury, rehabilitation is thought to enhance the reorganization and plasticity of spared supraspinal-propriospinal circuits, aiding functional recovery.

Background: Direct measurement of portal venous pressure (PVP) is invasive, so the hepatic venous pressure gradient (HVPG) is commonly measured to evaluate portal hypertension (PH). HVPG is the gold standard for estimating PVP but few reports have covered standardized measurement techniques.
Methods: This study validated standardized techniques for PVP measurement.
Atypical Motor-Predominant Presentation of Subacute Combined Degeneration of Spinal Cord Due to Vitamin B12 Deficiency: A Case Report of Stroke Mimicry in the Absence of Classic Symptoms.

Vitamin B12 deficiency is a prevalent condition that can lead to serious neurological disorders, including subacute combined degeneration (SCD) of the spinal cord, which can result in lasting damage if not promptly treated. This report discusses a unique case of a 53-year-old female patient who presented with a one-week history of gait instability and falls, ultimately diagnosed with SCD due to severe vitamin B12 deficiency. Notably, the patient exhibited an atypical presentation, lacking classic symptoms such as paraesthesia and hematologic abnormalities, which often accompany B12 deficiency.

Inhalation of prions into the nasal cavity is an efficient route of infection. Following inhalation of infectious prions, animals develop disease with a similar incubation period compared with per os exposure, but with greater efficiency. To identify the reason for this increased efficiency, we identified neural structures that uniquely innervate the nasal cavity and neural structures known to mediate neuroinvasion following oral infection and used immunohistochemistry to determine the temporal and spatial accumulation of prions from hamster tissue sections containing cell bodies and axons at 2-week intervals following prion exposure.
