The evolution of spinal cord procedures for pain closely followed the evolving understanding of the anatomy and workings of the pain pathways. Clinical observations often led to laboratory studies to define the pain pathways. More knowledge led to more and improved pain procedures. Postoperative observations led to better definition of pain perception. In addition, empirically derived pain proc...

This is a long-lasting increase in synaptic efficacy resulting from repetitive activation of the synapse. This process was first described in hippocampus, whereby high-frequency stimulation of afferent pathways leads to a potentiated post-synaptic response that can last for hours to days. It is a form of activity-dependent plasticity. LTPmay increase the efficiencyof pain transmission for weeks...

Body lateropulsion is known to be caused commonly by lateral medullary lesions but rarely by pontine lesions. It is also known to be associated with lesions of the dorsal spinothalamic tract or ascending graviceptive pathways. We herein report the case of a 75-year-old woman presenting with contralateral lateropulsion and cerebellar tremor caused by pons infarction. To our knowledge, this is th...

In rare cases restricted sensory deficits along the somatotopic topography of the spinothalamic tract can develop from a lateral medullary infarction. To our knowledge, isolated dermatomal sensory deficit as a single manifestation of a lateral medullary infarction has not been reported previously. A 58-year-old man presenting with sudden left-sided paresthesia complained of sensory deficit of p...

A 7-year-old boy underwent resection of a posterior fossa medulloblastoma. Two days later, he developed facial diplegia, left abducens nerve palsy, and mild hypalgesia below the neck. MRI documented 2 dot-like ischemic foci in the pons (figure). We diagnosed the unusual bilateral occurrence of Gasperini syndrome, a lesion of the sixth and seventh cranial nerve nuclei and the lateral spinothalam...

A rare case of subependymoma in a young patient presenting with sensory dysesthesia is reported. Computed tomography scan and magnetic resonance imaging revealed a posterior fossa mass occluding the fourth ventricle with infiltration to the right side immediately behind the pontine tegmentum and impinging on the right spinothalamic tract. Postoperative tumor histopathology revealed the classica...

COlWid.&lY demonstrated the developm% of "Celltral sensitiz&ion” in response to repeated discharge of primary. a&rent nociceptors (1, 2). Convergence of low-threshold mechanoreceptive neurons on spinothalamic tract*neurons that have been sensitized bv nociceptive input is thought account for tenderness around tlE site of injury. It now seems clear that abnormal persistence of this sensitization...

Complex regional pain syndrome (CRPS) type I in stroke patients is usually known to affect the hemiplegic upper limb. We report a case of CRPS presented in an ipsilesional arm of a 72-year-old female patient after an ischemic stroke at the left middle cerebral artery territory. Clinical signs such as painful range of motion and hyperalgesia of her left upper extremity, swollen left hand, and dy...
