BACKGROUND: Endothermal treatment of the great saphenous vein (GSV) has become the first-line treatment for superficial venous reflux. Nonthermal ablation has potential benefits for acceptability by patients and decreased risk of nerve injury. We performed a systematic review and meta-analysis to evaluate the efficacy of mechanochemical endovenous ablation (MOCA) and cyanoacrylate vein ablation (CAVA) for GSV incompetence. METHODS: MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane databases were searched for papers published between January 1966 and December 2016...

BACKGROUND: To evaluate early and long-term outcomes of symptomatic patients treated for in-stent carotid restenosis (ISR) with carotid bypass (CB). METHODS: Data were retrospectively collected from a prospectively compiled database on patients treated with CB in two high-volume Italian centers between 2008 and 2016, for symptomatic high-grade ISR after CAS. After carotid endarterectomy and stent removal, a greater saphenous vein (GSV) was preferentially employed as the graft; when the GSV was not accessible, a 6mm polytetrafluoroethylene (PTFE) graft was implanted...

Pyrethroid insecticides are widely used for pest control, in agriculture or in human public health commonly as a topical treatment for scabies and head lice. Exposure to pyrethroids such as permethrin or tetramethrin (TM) causes sensory alterations such as transient pain, burning, stinging sensations and paraesthesias. Despite the well-known effects of pyrethroids on sodium channels, actions on other channels that control sensory neuron excitability are less studied. Given the role of two-pore domain potassium (K2P) channels in modulating sensory neuron excitability and firing, both in physiological and pathological conditions, we examined the effect of pyrethroids on K2P channels mainly expressed in sensory neurons...

BACKGROUND AND OBJECTIVES: The popliteal nerve plexus contributes to afferent knee-pain conduction. It is mainly formed by genicular branches from the posterior obturator and the tibial nerves, innervating the intra-articular and posterior knee region. A subinguinal obturator nerve block alleviates pain after total knee arthroplasty. Reduced hip adductor motor function could be avoided by a posterior obturator nerve block inside the popliteal fossa. The aim of this study was to evaluate the spread of dye after a distal adductor canal (AC) injection to the popliteal fossa and coloring of the popliteal plexus and the genicular branch of the posterior obturator nerve by dissection...

BACKGROUND: Endovenous thermal ablation of the small saphenous vein carries a risk for sural nerve injury. Ablation above mid-calf level is recommended to avoid it. However, this strategy could not eradicate this complication. We present our results of consecutive 30 small saphenous vein thermal ablations which are performed after ultrasonographic identification of the sural nerve. METHODS: We studied 26 consecutive subjects with a total of 30 limbs. Ablation was performed proximal to the risk point by a 1470-nm diode laser...

INTRODUCTION: Anterior cruciate ligament (ACL) reconstruction can be performed with an autograft, which is most often harvested from the patient's hamstring tendon (HT) or patellar tendon (PT). However, autograft harvesting leads to morbidity that is by no means insignificant.A systematic review of literature was performed to define the incidence of complications related to graft harvesting and the methods to prevent these complications. MATERIALS AND METHODS: In March 2017, a systemic review of literature was performed using the keywords"harvesting", "harvest", "morbidity", "complication", "cruciate ligament"...

BACKGROUND: Endoluminal laser ablation is now considered the method of choice for treating greater saphenous vein insufficiency. General anesthesia and peripheral nerve blocks with sedation have the risk of post-procedural delay in discharge and prolonged immobilization with the risk of deep vein thrombosis. The main pain experienced by patients during the procedure is during the laser ablation and the multiple needle punctures given along and around the great saphenous vein. The aim of our study was to evaluate the safety and efficacy of blocking the femoral nerve only under ultrasound-guidance without sedation, to reduce or prevent pain during injectable tumescent anesthesia in endovenous laser ablation of the greater saphenous vein...

BACKGROUND: A subset of osteoarthritis (OA) patients experience joint pain with neuropathic characteristics. Mediators such as neutrophil elastase, a serine proteinase, may be released during acute OA inflammatory flares. We have previously shown that local administration of neutrophil elastase causes joint inflammation and pain via activation of proteinase-activated receptor-2 (PAR2). The aim of this study was to examine the contribution of endogenous neutrophil elastase and PAR2 to the development of joint inflammation, pain, and neuropathy associated with monoiodoacetate (MIA)-induced experimental OA...

Chemotherapy-induced neuropathic pain is a debilitating and common side effect of cancer treatment. Mitochondrial dysfunction associated with oxidative stress in peripheral nerves has been implicated in the underlying mechanism. We investigated the potential of melatonin, a potent antioxidant that preferentially acts within mitochondria, to reduce mitochondrial damage and neuropathic pain resulting from the chemotherapeutic drug paclitaxel. In vitro, paclitaxel caused a 50% reduction in mitochondrial membrane potential and metabolic rate, independent of concentration (20-100 μmol/L)...

We describe a case of entrapment neuropathy of the infrapatellar branch of the saphenous nerve as it pierces sartorius muscle. This is a rare cause of anteromedial knee pain that is easily overlooked and may be mistaken as arising from other anatomical structures in that region. The pain was successfully treated by partially dividing the sartorius muscle and translocating the nerve away from the site of entrapment. It is important to consider entrapment neuropathy of the infrapatellar branch of the saphenous nerve as a differential diagnosis when assessing a patient with anteromedial knee pain...

BACKGROUND AND OBJECTIVES: Only a few different approaches are currently utilized for saphenous nerve block. Our study aimed to compare two different ultrasound (US)-guided saphenous nerve blocks and designed this study to test the hypothesis that the medial infracondylar approach has more success rate than the subsartorial approach applied in saphenous nerve blockage. METHODS: The study included 76 patients (18-65 years old) with the American Society of Anesthesiologists physical status of I-III, who were scheduled for below-knee surgery by the orthopedics clinic...

Previous research identified TRPM8 and TRPA1 cold transducers with separate functions, one being functional in the non-noxious range and the second one being a nociceptive transducer. TRPM8-deficient mice present overt deficits in the detection of environmental cool, but not a lack of cold avoidance and TRPA1-deficient mice show clear deficits in some cold nocifensive assays. The extent of TRPA1's contribution to cold sensing in vivo is still unclear, because mice lacking both TRPM8 and TRPA1 (DKO) were described with unchanged cold avoidance from TRPM8(-/-) based on a two-temperature-choice assay and by c-fos measurement...

Chronic exertional compartment syndrome is a rare cause of lower leg pain incurred during sports activities and typically affects young athletes who need to return to their activity level as quickly as possible. Nonoperative treatments are often unsuccessful and fasciotomy of the involved compartment is the treatment of choice. Endoscopically assisted release of the anterior and deep compartments is proven to be safe and effective. Endoscopically assisted deep posterior compartment release via an incision 1 to 3 cm behind the medial tibial border has high risk of injury to the great saphenous and perforating veins and the saphenous nerve...

The current decerebration procedures discard the role of the thalamus in the motor control and decortication only rules out the brain cortex part, leaving a gap between the brain cortex and the subthalamic motor regions. In here we define a new preparation denominated Brain Cortex-Ablated Cat (BCAC), in which the frontal and parietal brain cortices as well as the central white matter beneath them were removed, this decerebration process may be considered as suprathalamic, since the thalamus remained intact...

AIMS: Percutaneous tibial nerve stimulation (PTNS) is an effective neuromodulation therapy for treating overactive bladder (OAB). The therapeutic effects are achieved by repeatedly applying electrical stimulation through a percutaneous needle electrode that is used to target the tibial nerve (TN). Anatomical studies indicate there can be multiple saphenous nerve (SAFN) branches located near the site of electrical stimulation, and therefore we investigated the possibility of evoking a bladder-inhibitory reflex by electrically activating the SAFN...
