Intramedullary hemorrhagic necrosis occurs early after spinal cord injury at the site of injury and adjacent segments. It is considered harmful because of its potential to aggravate secondary injury, and to interfere with axonal regeneration; it might also lead to an unfavorable environment for intralesional implants. Removal of hemorrhagic necrosis has been attempted before with variable resul...

BACKGROUND AND IMPORTANCE A porous bioresorbable polymer scaffold has previously been tested in preclinical animal models of spinal cord contusion injury to promote appositional healing, spare white matter, decrease posttraumatic cysts, and normalize intraparenchymal tissue pressure. This is the first report of its human implantation in a spinal cord injury patient during a pilot study testing ...

Neurofibromas are occasionally present in spinal roots; however, an intramedullary neurofibroma is especially rare. Although a few cases of intramedullary neurofibromas in cervical spinal cord have been reported, to the best of our knowledge, there are no reports of intramedullary neurofibromas in thoracic spinal cord, and moreover, no reports have clearly reported immunohistochemical findings....

It takes a baby at least two years to learn to interpret certain sensations as indicating that the bladder needs to be emptied. When the afferent pathway from the bladder in the spino-thalamic tract has been divided, these specific sensations are no longer experienced. However, when this pathway from the bladder has been divided and the normal sensation underlying the desire to micturate has th...

was used to localize the lesion. The lesion was located relatively deep into the brainstem but was closer to the posterior surface and was to the right of the midline. An incision was taken in the region of the pontomedullary junction in the midline at the level of the lesion. Blunt dissection was used in a vertical direction within a limit of about 4-5 mm using number 7 Rhoton microdissector. ...

Visceral noxious stimulation induces central neuronal plasticity changes and suggests that the c-AMP-dependent protein kinase (PKA) signal transduction cascade contributes to long-term changes in nociceptive processing at the spinal cord level. Our previous studies reported the clinical neurosurgical interruption of post synaptic dorsal column neuron (PSDC) pathway by performing midline myeloto...

www.eymj.org Hun Jae Lee was born on November 11, 1921 in Unsu-myeon, a village of Goryeong-gun, in the province of Gyeongbuk, Korea (Fig. 1). He was the eldest son of Bong Hwan Lee, a patriot who served 3 years in prison for his independence act, and Yeon Bun Ihm. He graduated from Severance Hospital Medical School in 1944 and completed his medical internship in Pyongyang Christian Hospital in...

The problem of disabling osteoarthritis of the hip is difficult when only one hip is involved, far more so when both are affected. The orthopaedic surgeon is largely concerned with the improvement of function, and with operations of choice rather than of necessity ; but in cases of severe osteoarthritis of the hip, with its progressive interference in work, recreation and sleep, any relief that...

Injury to the nerves in animals are related to the pain models i.e., partial/total nerve transaction/ligation/chronic nerve constriction. Neuropathic pain can be a disabling side effect of cancer treatment. Chemotherapy induced peripheral neuropathy is toxic neuropathy that results from direct injury to peripheral nervous system. Experimental details of following behavior models observed in ani...
