Dorsal root ganglion toll-like receptor 4 signaling contributes to oxaliplatin-induced peripheral neuropathy.

Activation of toll-like receptor 4 (TLR4) in the dorsal root ganglion (DRG) and spinal cord contributes to the generation of paclitaxel-related chemotherapy-induced peripheral neuropathy (CIPN). Generalizability of TLR4 signaling in oxaliplatin-induced CIPN was tested here. Mechanical hypersensitivity developed in male SD rats by day 1 after oxaliplatin treatment, reached maximum intensity by day 14, and persisted through day 35.

Abdominal tattoo can be useful to avoid a midline abdominal incision.

We report a case in which abdominal tattoo margins were modified and used to hide the surgical incision for desmoid tumour removal. Our patient is a 37-year-old female with history remarkable for atrial septal defect closure at the age of ten, but not for previous abdominal surgeries or trauma. A desmoid tumour diagnosis was made upon needle biopsy of the 5 × 4 cm mass confined to the rectus abdominis.

Lidocaine Stimulates the Function of Natural Killer Cells in Different Experimental Settings.

Background: One of the functions of natural killer (NK) cells is to eliminate cancer cells. The cytolytic activity of NK cells is tightly regulated by inhibitory and activation receptors located in the surface membrane. Lidocaine stimulates the function of NK cells at clinically relevant concentrations.

Inflammation and pro-resolution inflammation after hepatobiliary surgery.

Background: The magnitude of the perioperative inflammatory response plays a role in surgical outcomes. However, few studies have explored the mechanisms of the resolution of inflammation in the context of surgery. Here, we described the temporal kinetics of interleukin-6, cortisol, lipoxin A4, and resolvin D in patients who underwent oncologic liver resections.

Impaired Immune Function in Patients Undergoing Surgery for Bone Cancer.

Background: Natural killer (NK) cells undergo quantitative and functional changes after oncological surgery.

Patients And Methods: After Institutional Review Board approval, the count and function of NK cells from patients with malignant bone tumors were assessed only days 1, 3, 5 and during first postoperative visit, and compared with preoperative values. The serum concentrations of interleukins (IL)-2, -4 and -6 were also measured before and after surgery.
