According to the parameters we studied, adding parenteral omega-3 and omega-6 fatty acids to the nutrition regimen of rats treated with dexamethasone does not seem to have adverse effects on wound healing, and effects on wound healing may not need to be considered when determining if these agents should be supplemented in nutrition support regimens.

Simple meningoceles are infrequent forms of dysraphism and are often benign. These lesions are usually associated with other congenital spinal anomalies, and are typically diagnosed in childhood. Most become symptomatic in childhood because of progressive spinal cord or nerve root tethering. This article describes the case of a 47-year-old man who presented with a sac in his posterior cervical region that had been leaking colorless fluid for 3 months. He was also having difficulty walking and complained of stiffness in his lower extremities. Cervical magnetic resonance imaging revealed a cystic mass in the region of the C4 to C5 laminae. Partial laminectomies were performed (lower portion C4 lamina, upper portion C5 lamina), the sac was totally excised, and tissue tethering the spinal cord were cut. There was no recurrence of symptoms in 12 months of follow-up. Although in cases where a cervical meningocele-myelomeningocele is detected at any time, early treatment is essential to eliminate the high risk of future neurological impairment. This is the first report of an untreated cervical meningocele manifesting symptoms in adulthood.

The literature concerning general anesthesia in paramyotonic patients is limited. We report a case of paramyotonia congenita in a 2-mo-old male infant undergoing surgery for pyloric stenosis and inguinal hernia after an uneventful anesthesia.

At the cellular level, spinal cord injury (SCI) provokes an inflammatory response that generates substantial secondary damage within the cord, but also may contribute to its repair. The aim of this study was to investigate the effects of inflammatory response associated with SCI in cutaneous wound healing and on expression of transforming growth factor-beta1 (TGF-beta1) and platelet-derived growth factor (PDGF)-A at the wound site in rats. At the 14th day analysis, the mean TGF-beta1 score in trauma group (I) was significantly lower than that in control group (C) (2.60 +/- 0.90 vs. 3.64 +/- 0.37, respectively; p < 0.05). The mean score for PDGF-A expression in group I was similar to the corresponding value in group C (2.42 +/- 0.74 vs. 2.94 +/- 0.72, respectively). Compared to group C, group I had significantly lower mean scores for epidermal and dermal regeneration, but higher mean scores for granulation tissue thickness and similar scores for angiogenesis. The dermal layer contains diffuse deposition of collagen fibers that are not organised as in control rat skin, and intraepidermal and subepidermal vasocongestion is distinct. Based on the results on the parameters evaluated in the study, experimental SCI in rats results in delay in wound healing and low intensity of TGF-beta1 in the dorsal wound-tissue specimens.
