OBJECTIVE: To assess the long-term outcome of computed tomography-guided radiofrequency ablation (CT-guided RFA) in patients with suspected osteoid osteoma (OO). MATERIALS AND METHODS: Single-center retrospective study. Patients with clinical suspicion and imaging diagnosis of osteoid osteoma were treated by CT-guided RFA using the same device with either a 7- or 10-mm active tip electrode. Specific precautions were applied in case of articular or spinal OO. Patients were contacted by phone to evaluate the long-term outcome in terms of pain, ability to perform daily activities (including sports), and long-term complications...

Autografts represent the gold standard for peripheral nerve reconstruction but their limited availability, the discrepancy of nerve caliber and long surgical times are drawbacks. Allografts have therefore become a valid alternative option. In particular, acellular nerve allografts (ANAs) rather than fresh allografts do not need immunosuppression and appear to be safe and effective based on recent studies. An innovative method was conceived to obtain ANAs, so as to speed up nerve decellularization, without compromising nerve architecture, and without breaking the asepsis chain...

Diabetes, a major lifestyle disorder, has become a global burden, and the prevalence rates are rising steeply in developing economies. Rapid socioeconomic transition with urbanization and industrialization are the main causes for the global diabetes epidemic. Among developing economies, the highest increase in number of people with diabetes is in China followed by India. In India, the epidemic of diabetes continue to increase and is experiencing a shift in diabetes prevalence from urban to rural areas, the affluent to the less privileged and from older to younger people...

Anti-MAG (myelin-associated glycoprotein) neuropathy is a disabling autoimmune peripheral neuropathy caused by monoclonal IgM autoantibodies that recognize the carbohydrate epitope HNK-1 (human natural killer-1). This glycoepitope is highly expressed on adhesion molecules, such as MAG, present in myelinated nerve fibers. Because the pathogenicity and demyelinating properties of anti-MAG autoantibodies are well established, current treatments are aimed at reducing autoantibody levels. However, current therapies are primarily immunosuppressive and lack selectivity and efficacy...

Neuroglobin (NGB), distributed mainly in central and peripheral nervous systems, is a nerve globin with neuroprotective effects against oxidative stress resulting from hypoxia and ischemia. Recent studies have indicated that the expression of NGB is related to neurodegenerative disorders and cancers, but the molecular mechanisms for its transcriptional regulation and protection are not well defined. Here, we report that the expression of NGB in glioma is grade related and is negatively regulated by PPARγ. Specific PPARγ agonist reduces the expression of NGB, while its inhibitor enhances the expression...

α-Lipoic acid, or thioctic acid, (ALA) is the most applicable pharmacological drug for treatment of diabetic polyneuropathy. The article explores the results of experimental studies on the α-lipoic acid effect on mechanisms of peripheral nerves affection in hyperglycemia as well as the data of numerous randomized controlled trials and meta-analyses on studying ALA efficacy in symptomatic diabetic polyneuropathy. It has been shown that amelioration of patients with diabetic polyneuropathy is observed both for ALA infusions and tableted form of the drug...

Minocycline, a glial suppressor, prevents behavioural hypersensitivities in animal models of peripheral nerve injury. However clinical trials of minocycline in human studies have produced mixed results. This study addressed two questions: can repeated injections of hypertonic saline (HS) in humans induce persistent hypersensitivity? Can pre-treatment with minocycline, a tetracycline antibiotic with microglial inhibitory effects, prevent the onset of hypersensitivity? Twenty seven healthy participants took part in this double-blind, placebo-controlled study, consisting of six test sessions across 2 weeks...

Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of anticancer treatment with microtubule-targeted agents (MTAs). The frequency of severe CIPN, which can be dose limiting and even life threatening, varies widely among different MTAs. For example, paclitaxel induces a higher frequency of severe CIPN than does eribulin. Different MTAs also possess distinct mechanisms of microtubule-targeted action. Recently, we demonstrated that paclitaxel and eribulin differentially affect sciatic nerve axons, with paclitaxel inducing more pronounced neurodegenerative effects and eribulin inducing greater microtubule stabilizing biochemical effects...

Neuropathic pain resulting from damage or dysfunction of the nervous system is a highly debilitating chronic pain state and is often resistant to currently available treatments. It has become clear that neuroinflammation, mainly mediated by proinflammatory cytokines and chemokines, plays an important role in the establishment and maintenance of neuropathic pain. Chemokines were originally identified as regulators of peripheral immune cell trafficking and were also expressed in neurons and glial cells in the central nervous system...

Thousands of people each year suffer from peripheral nerve injury. Treatment options are limited, and recovery is often incomplete. Treadmill exercise can enhance nerve regeneration; however, this appears to occur in a sex-dependent manner. Females respond best to short duration, high speed interval training; whereas, males respond best to slower, continuous training. Previous studies have shown a role for testosterone in this process, but the role of estrogen is unknown. To evaluate the role of estrogen signaling in treadmill exercise, we blocked estrogen receptor (ER) signaling during treadmill exercise in males and female wild type mice...

Background Optical coherence tomography angiography (OCTA) offers the possibility to visualize, non-invasively, blood vessels of the retina. In vascular tumors, especially hemangioblastomas in Hippel-Lindau disease, new information can be obtained with OCTA concerning structure of the tumor, tumor activity and treatment success. Patients Ten eyes of 10 patients with retinal hemangioblastoma in Hippel-Lindau disease were included. The age of the patients ranged from 19 years to 65 years (median 44 years). Results A total of 10 active and one inactive hemangioblastomas were examined with OCTA...

Objectives. : Opiate analgesics are the most effective treatments for severe pain, but their clinical utility is often hampered by the development of analgesic tolerance. There are striking similarities between morphine actions and neuropathic pain. We have demonstrated that B vitamins can attenuate neuropathic pain after peripheral nerve injury, sensory neuron inflammation/compression, and transient spinal cord ischemia. Given this similarity, the present study investigated whether B vitamins might be able to modify the antinociceptive effect of morphine as well as morphine tolerance in mice...

REVIEW
O Walusinski
The trauma of World War I had a lasting impact on clinician and physiologist Jules Tinel (1879-1952). His treatment of peripheral nervous system injuries led him, in 1917, to describe the eponymous sign that he linked to activity of the sympathetic nervous system. Among the sequelae of nerve injuries, he was confronted with causalgia that he attributed, here again, to the autonomic nervous system, the main focus of his laboratory research throughout his career. Tinel's sign became so well known that it eclipsed the originality of his seminal descriptions of exertional headache and of hypertensive emergency caused by pheochromocytoma, which could also have been associated with his name...

In this study, we sought to determine the efficacy of tempol on multiple neuropathic endpoints in a diet-induced obese mouse, a model of pre-diabetes, and a high-fat fed low-dose streptozotocin treated mouse, a model of type 2 diabetes. Tempol (4-hydroxy-2,2,6,6-tetramethylpiperdine -1-oxyl) is a low molecular weight, water soluble, membrane permeable, and metal-independent superoxide dismutase mimetic that has been widely used in cellular studies for the removal of intracellular and extracellular superoxide...

PURPOSE OF REVIEW: Bell's palsy is a common outpatient problem, and while the diagnosis is usually straightforward, a number of diagnostic pitfalls can occur, and a lengthy differential diagnosis exists. Recognition and management of Bell's palsy relies on knowledge of the anatomy and function of the various motor and nonmotor components of the facial nerve. Avoiding diagnostic pitfalls relies on recognizing red flags or features atypical for Bell's palsy, suggesting an alternative cause of peripheral facial palsy...

Circadian rhythm (CR) plays a critical role in the treatment of several diseases. However, the role of CR in the treatment of peripheral nerve defects has not been studied. It is also known that the pulsed electromagnetic fields (PEMF) can provide a beneficial microenvironment to quicken the process of nerve regeneration and to enhance the quality of reconstruction. In this study, we evaluate the impact of CR on the promoting effect of PEMF on peripheral nerve regeneration in rats. We used the self-made "collagen-chitosan" nerve conduits to bridge the 15-mm nerve gaps in Sprague-Dawley rats...
