13. The Diagnosis and Treatment of Peripheral Nerve Injuries

14. Electron-microscope observations on the effects of localized crush injuries on the connective tissues of peripheral nerve.

15. Nerve compression injuries due to traumatic false aneurysm.
Experience with 17 patients with delayed onset of compression neuropraxia due to hemorrhage following nonoperative treatment of penetrating arterial injuries is presented. Fifteen cases involved the arteries of the neck shoulder girdle and upper extremity and two the gluteal vessels. This resulted in dysfunction of components of the brachial plexus, median u

16. Large-scale functional reorganization in adult monkey cortex after peripheral nerve injury.
In adult monkeys, peripheral nerve injuries induce dramatic examples of neural plasticity in somatosensory cortex. It has been suggested that a cortical distance limit exists and that the amount of plasticity that is possible after injury is constrained by this limit. We have investigated this possibility by depriving a relatively large expanse of cortex by

17. Targeted expression of a multifunctional chimeric neurotrophin in the lesioned sciatic nerve accelerates regeneration of sensory and motor axons
Peripheral nerve injury markedly regulates expression of neurotrophins and their receptors in the lesioned nerve. However, the role of endogenously produced neurotrophins in the process of nerve regeneration is unclear. Expression of a multifunctional neurotrophin, pan-neurotrophin-1 (PNT-1), was targeted to the peripheral nerves of transgenic mice by using

18. Nerve Allotransplantation as it Pertains to Composite Tissue Transplantation
Nerve allografts provide a temporary scaffold for host nerve regeneration and allow for the repair of significant segmental nerve injuries. From rodent, large animal, and nonhuman primate studies, as well as clinical experience, nerve allografts, with the use of immunosuppression, have the capacity to provide equal regeneration and function to that of an aut

19. Does a neuroimmune interaction contribute to the genesis of painful peripheral neuropathies?
Painful peripheral neuropathies are precipitated by nerve injury from disease or trauma. All such injuries will be accompanied by an inflammatory reaction, a neuritis, that will mobilize the immune system. The role of the inflammation itself is difficult to determine in the presence of structural damage to the nerve. A method has been devised to produce

20. The number and size of axons central and peripheral to inferior alveolar nerve injuries in the cat.
We have observed the effect of three different lesions on the inferior alveolar nerve of the cat. If the nerve is transected and the cut ends reapposed there is no significant difference between the number of myelinated axons in the nerve proximal to the lesion and the number in contralateral control nerves at 9 or 15 weeks post-operatively. Counts distal to

21. Changes in sensation after nerve injury or amputation: the role of central factors.
Dynamic changes in somatosensory cortical maps are known to occur in experimental animals subjected to peripheral nerve transection or amputation. To study the sensory effects of central nervous system adaptation to temporary or permanent loss of input from a part of the hand, multimodality quantitative sensory tests were carried out in 11 patients with comp

22. Acceleration of neuromuscular re-innervation by triiodothyronine.
The right sciatic nerve was crushed in 84 rats, 42 of which were injected daily with triiodothyronine (T3; 1-0 mug/kg body weight, subcutaneously) while the others served as untreated controls. Rats in both groups were killed in groups of 6 at intervals of 5 days and the re-innervation of the tibialis anterior muscle was examined histologically using the bro

23. Somatosensory cortical plasticity in adult humans revealed by magnetoencephalography.
Microelectrode recordings in adult mammals have clearly demonstrated that somatosensory cortical maps reorganize following peripheral nerve injuries and functional modifications; however, such reorganization has never been directly demonstrated in humans. Using magnetoencephalography, we have been able to demonstrate the somatotopic organization of the hand

24. Survival and regeneration of rubrospinal neurons 1 year after spinal cord injury
Scientific interest to find a treatment for spinal cord injuries has led to the development of numerous experimental strategies to promote axonal regeneration across the spinal cord injury site. Although these strategies have been developed in acute injury paradigms and hold promise for individuals with spinal cord injuries in the future, little is known abo
