BACKGROUND: Postherpetic neuralgia (PHN) is a chronic neuropathic pain that results from alterations of the peripheral nervous system in areas affected by the herpes zoster virus. The symptoms include pain, paresthesia, dysesthesia, hyperalgesia, and allodynia. Despite the availability of pharmacological treatments to control these symptoms, no treatments are available to control the underlying pathophysiology responsible for this disabling condition. METHODS/DESIGN: Patients with herpes zoster who are at least 50 years old and have a pain score of 4 or higher on a visual analogue scale (VAS) will be recruited...

BACKGROUND AND OBJECTIVES: Lidocaine 5% medicated plaster is the first lidocaine containing product for chronic use. As no previous investigations have been conducted to evaluate the population pharmacokinetics of long-term exposure to lidocaine 5% medicated plasters, further insights into the evaluation of the pharmacokinetic properties of lidocaine and its metabolites were needed for the assessment of its safety. METHODS: The population pharmacokinetic properties of lidocaine and its metabolites were evaluated after multiple applications of lidocaine 5% medicated plasters based on data collected for up to 14...

BACKGROUND: Chronic pelvic, perineal and gluteal neuralgia is often experienced in a similar way to neuropathic pain, in the territories of four nerves: ilio-inguinal, pudendal, inferior cluneal and posterior gluteal nerves. These pains are often refractory to medical treatment based on the use of systemic molecules with disabling adverse effects and surgical procedure may be necessary. OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of treatment with a high-concentration capsaicin patch in these indications...

OBJECTIVE: The ubiquitous use of polypropylene mesh in hernia surgery has spawned a new clinical syndrome: chronic post-herniorrhaphy neuralgia. A subset of that clinical picture is dysejaculation, sexual pain, and orchialgia. We propose to identify the processes that lead to that pain. SUMMARY OF BACKGROUND DATA: Specimens of vas adherent to polypropylene mesh, explanted in an attempt to control severe, life-changing inguinodynia are extremely difficult to obtain...

Chronic nerve compression (CNC), such as carpal tunnel syndrome (CTS), is a common cause of peripheral nerve dysfunction and chronic peripheral nerve pain. Current available treatments for CNC are ineffective as they usually aim to alleviate symptoms at the acute phase with limited capability towards restoring injured nerve function. New approaches for effective recovery of CNC injury are highly desired. Here we report for the first time a tissue-engineered approach for the repair of CNC. A genipin cross-linked chitosan-sericin 3D scaffold for delivering nerve growth factor (NGF) was designed and fabricated...

BACKGROUND: Trigeminal neuralgia (TN) is a chronic brain condition involving the trigeminal nerve and characterized by severe and recurrent facial pain. While the etiology of TN has been researched extensively, there is a lack of convergence on the exact physiological processes leading to pain symptoms. This review seeks to better elucidate the underlying pathophysiology of TN by analyzing the outcomes of studies that utilize magnetic resonance (MR) structural imaging and diffusion-weighted imaging (DWI) to examine nerve damage in patients with TN...

BACKGROUND: Post-herpetic neuralgia (PHN), which develops after the resolution of a herpes zoster eruption, is an exceptionally drug-resistant neuropathic pain. The unsatisfactory management of PHN partly results from the difficulty in dissecting out its contributing factors due to the complexity of PHN mechanism. METHODS: Here, to elaborate our understanding of the PHN mechanism and to establish a basis for effective therapeutic strategies, we comprehensively investigated the contributions of multiple factors to PHN severity...

Classical trigeminal neuralgia (TN) is a chronic pain disorder that has been described as one of the most severe pains one can suffer. The most prevalent theory of TN etiology is that the trigeminal nerve is compressed at the root entry zone (REZ) by blood vessels. However, there is significant evidence showing a lack of neurovascular compression (NVC) for many cases of classical TN. Furthermore, a considerable number of patients who are asymptomatic have MR evidence of NVC. Since there is no validated animal model that reproduces the clinical features of TN, our understanding of TN pathology mainly comes from biopsy studies that have limitations...
