A study of the relation between the development of mechanical allodynia and the reorganization of primary afferent terminals in the sensory lamina of the rat spinal cord dorsal horn after partial dorsal root ganglion injury in rats. ⋯ Morphologic change in spinal cord dorsal horn lamina II occurs after partial dorsal root ganglion injury. This change may have significance in the pathogenesis of chronic mechanical allodynia after partial dorsal root ganglion injury.

The results from cervical laminoplasty in 18 patients with diabetes mellitus were compared with results from the same procedure in 34 nondiabetic patients matched for age, gender, and disease. ⋯ Although patients with diabetes mellitus who had cervical myelopathy experienced benefits from cervical laminoplasty similar to those of nondiabetic patients, the patients with diabetes were more likely to have wound complication. Furthermore, the negative correlation between the recovery rate and the preoperative HbA1 value might suggest that long-term diabetes control of more than 2 to 3 months before surgery at least is recommended for a favorable surgical outcome.
