OBJECTIVE: Inflammatory and immune mechanisms play important roles in the pathogenesis of neuropathic pain. Ceftiofur, a third-generation cephalosporin, has anti-inflammatory effects by inhibiting tumor necrosis factor (TNF)-α, interleukin (IL)-1β, nuclear factor (NF)-κB, and mitogen-activated protein kinase (MAPK) signaling. This study aimed to investigate the effect of ceftiofur on hyperalgesia and allodynia in neuropathic rats and to define the possible contribution of immune mechanisms to this effect...

The effective treatment of patients suffering from neuropathic pain remains challenging. Dexmedetomidine (DEX) possesses anti-inflammatory activity. However, the role of DEX in neuropathic pain is still unclear. The aim of the present study was to examine DEX an α2-adrenoceptor agonist could improve pain hypersensitivity and reduce inflammatory in a chronic constriction injury (CCI) model of the sciatic nerve in Sprague-Dawley rats. Dex was intrathecally administrated 1-h after operation. The paw mechanical withdrawal threshold (MWT) and paw withdrawal thermal latency (PWTL) were measured on day 1 before operation and on days 1, 7, 14 and 21 after operation, respectively...

The dorsal horn (DH) of the spinal cord is the integrative center that processes and transmits pain sensation. Abnormal changes in ion channel expression can enhance the excitability of pain-related DH neurons. Sodium-activated potassium (KNa) channels are highly expressed particularly in the central nervous system; however, information about whether rat DH neurons express the SLICK channel protein is lacking, and the direct effects on SLICK in response to inflammation and the potential signaling pathway mediating such effects are yet to be elucidated...

Metastatic bone pain is the single most common form of cancer pain, and persists as a result of peripheral and central inflammatory, as well as, neuropathic mechanisms. Here, we provide the first characterization of sphingolipid metabolism alterations in the spinal cord occurring during cancer-induced bone pain (CIBP). Following femoral arthrotomy and syngenic tumor implantation in mice, ceramides decreased with corresponding increases in sphingosine and the bioactive sphingolipid metabolite, sphingosine 1-phosphate (S1P)...

Bone cancer pain commonly occurs when tumors originating in the breast, prostate or lung metastasize to long bones, spinal vertebrae and/or the pelvis. However, the underlying mechanisms of bone cancer pain remain largely unknown. The present study aimed to determine the role of spinal tumor necrosis factor-α (TNF-α) in the development of bone cancer pain. Osteosarcoma NCTC 2472 cells were implanted into the femoral intramedullary space of C3H/HeJ mice to establish a bone cancer model. Resulting pain-related behaviors, namely spontaneous foot lifting, paw withdrawal mechanical threshold and paw withdrawal thermal latency were observed prior to inoculation and on days 3, 5, 7, 10 and 14 thereafter...

Alpha7 nicotinic acetylcholine receptor (α7nAChR) has been reported to alleviate neuroinflammation. Here, we aimed to determine the role of autophagy in α7nAChR-mediated inhibition of neuroinflammation and its underlying mechanism. Experimental autoimmune encephalomyelitis (EAE) mice and lipopolysaccharide-stimulated BV2 microglia were used as in vivo and in vitro models of neuroinflammation, respectively. The severity of EAE was evaluated with neurological scoring. Autophagy-related proteins (Beclin 1, LC3-II/I, p62/SQSTM1) were detected by immunoblot...

A schwannoma is a benign nerve sheath tumor derived from Schwann cells. They are usually small and solitary tumors more frequently localized in cranial nerves and the spinal cord and rarely in the limbs. Some cases have been reported involving extremities (mainly the upper ones) but with a small size. Cases of big size schwannomas unrelated to a neurofibromatosis are very rare. We report the case of a 25 year old patient, with a giant schwannoma which invaded the ischiatic region reaching the triceps surae.

Giant cell tumor (GCT) is a benign, locally aggressive tumor that rarely occurs in the spine. They usually occur in patients between 20 and 40 years of age; some patients with GCT present in hospital with pregnancy. The management of these patients can be challenging. The current study reports a case of GCT located in the sixth thoracic vertebra of a 31-year-old female at 34 weeks of gestation. An osteolytic lesion, 3.5 cm × 3.5 cm in diameter, was identified on CT. An MRI test of the lesion revealed a soft tissue mass involving the T 6-7 vertebrae, extending to the right pedicle of the T 6 vertebra and causing significant spinal cord compression...
