Combinations of fibroblasts (Fbs) and corresponding epithelial cells have been widely used in many tissues, such as the skin and breast tissues, to augment tissue repair and remodeling. Recently, a large amount of new data has indicated that nerve Fbs play critical roles in Schwann cells (SCs) and axons in vitro . However, little is known regarding the effects of co-transplanting nerve Fbs and SCs on peripheral nerve repair in vivo . The aim of this study was to investigate the effect of co-transplanting sciatic nerve Fbs (SN-Fbs) and sciatic nerve SCs (SN-SCs) on nerve regeneration...

BACKGROUND AND OBJECTIVE: Nowadays, pulsed radiofrequency (PRF) is being used to control several types of musculoskeletal pain. Herein, we report a successful application of ultrasound (US)-guided PRF for a patient with refractory sciatic neuropathic pain. CASE REPORT: We applied US-guided PRF to a 50-year-old man, suffering from refractory neuropathic pain on the left foot following sciatic neuropathy for a period of approximately 6 months. We performed PRF on the level of piriformis muscle because the lesion of the sciatic nerve was presented digitally from the level of piriformis muscle on the magnetic resonance images...

We describe the clinical presentation of a patient with spastic diplegia, and its unique perioperative challenges. Opioids and antispasmodic medications are the primary therapy for managing pain and spasticity in the perioperative setting. However, such combination results in several side-effects and their sedative properties are synergistic. A 64-year-old woman with a history of spastic diplegia and an intrathecal baclofen pump for the treatment of her lower extremity spasticity was scheduled for a third elective left knee arthroplasty...

Garret Weber, Sherry Liao, Micah Alexander Burns
Sickle cell crisis, or vaso-occlusive crisis (VOC), is a major cause of hospitalizations for adults and children with sickle cell disease, and is associated with increased morbidity and mortality. Despite prompt pharmacological treatment and multimodal pain management, acute pain during a VOC is often not adequately controlled in the pediatric population. We placed a continuous popliteal sciatic nerve block under ultrasound guidance in a pediatric patient for localized refractory pain during a VOC, resulting in improved pain control with preserved sensorimotor function...

We performed a randomised double-blind pilot study in 16 healthy volunteers to investigate the success rate for placing a new suture-method catheter for sciatic nerve block. A catheter was inserted into both legs of volunteers and each was randomly allocated to receive 15 ml lidocaine 2% through the catheter in one leg and 15 ml saline in the other leg. Successful placement of the catheter was defined as a 20% decrease in maximum voluntary isometric contraction for dorsiflexion of the ankle. Secondary outcomes were maximum voluntary isometric contraction for plantar flexion at the ankle, surface electromyography and cold sensation...

Neuropeptide tyrosine (NPY) and its associated receptors Y1R and Y2R have been previously implicated in the spinal modulation of neuropathic pain induced by total or partial sectioning of the sciatic nerve. However, their role in chronic constrictive injuries of the sciatic nerve has not yet been described. In the present study, we analyzed the consequences of pharmacological activation of spinal Y1R, by using the specific Y1R agonist Leu31 Pro34 -NPY, in rats with chronic constriction injury (CCI). CCI and sham-injury rats were implanted with a permanent intrathecal catheter (at day 7 after injury), and their response to the administration of different doses (2...

BACKGROUND AND OBJECTIVES: While benefits of regional anesthesia in total hip arthroplasty (THA) are well documented, data describing the incidence of complications related to the use of posterior lumbar plexus blockade for THA remain limited. Our primary aim was to evaluate the incidence of infectious, bleeding, and neurological complications related specifically to the use of continuous posterior lumbar plexus block for elective THA. METHODS: We reviewed the electronic medical records of all adult patients who underwent elective THA with continuous posterior lumbar plexus blockade between December 1, 2004, and April 30, 2015, using the Mayo Clinic Total Joint Registry...

BACKGROUND: New catheter-over-needle (CON) technology for continuous peripheral nerve blockade has emerged, but its effect on the risk of perineural catheter tip dislocation is unknown. Less flexible catheters may be more likely to migrate away from the nerve with simulated patient movement. In the present study, we evaluated catheter tip migration between CON catheters and traditional catheter-through-needle (CTN) catheters during ultrasound-guided short-axis in-plane (SAX-IP) insertion...

BACKGROUND AND OBJECTIVES: Patients undergoing major elective ankle surgery often experience pain from the saphenous nerve territory persisting beyond the duration of a single-injection saphenous nerve block. We hypothesized that perineural dexamethasone as an adjuvant for the saphenous nerve block prolongs the duration of analgesia and postpones as well as reduces opioid-requiring pain. METHODS: Forty patients were included in this prospective, randomized, controlled study...

We compared the effect of two different positions of a sciatic nerve catheter within the popliteal fossa on local anaesthetic consumption and postoperative analgesia in patients undergoing day-case hallux valgus repair. Eighty-four patients were randomly allocated to receive a sciatic nerve catheter either between the tibial and peroneal components (sciatic group) or medial to the tibial nerve (tibial group). The primary endpoint was postoperative local anaesthetic consumption, while secondary endpoints were pain scores, number of occasions where sleep was disturbed by pain and incidence of insensate limb and foot drop at 24 h and 48 h postoperatively...
