BACKGROUND: The current pain assessment methods are strongly subjective and easily affected by outside influences, and there is an urgent need to develop a reliable objective and quantitative pain-monitoring indicator. The aim of this study was to evaluate the feasibility of using Pain index (Pi) to assess pain symptoms in pain patients. METHODS: Subjects were enrolled from patients seeking treatment at Pain Medicine Center of China Medical University Aviation General Hospital from October 2015 to December 2016, such as postherpetic neuralgia, spinal cord injury, femoral head necrosis, lumbar disc herniation, trigeminal neuralgia, complex regional pain syndrome, perineal pain, phantom limb pain, etc...

BACKGROUND: As herpes zoster progresses via postherpetic neuralgia (PHN) to well-established PHN, it presents its recalcitrant nature to the treatment. At this point, the well-established PHN is fixed as a non-treatable, but manageable chronic painful neuropathic disorder. This study evaluated the incidence of complete relief from PHN according to PHN duration at their first visit, and the other factors influencing it. METHODS: A retrospective chart review was performed on patients with PHN at a university-based pain clinic over 7 years...

Numerous interventions for neuropathic pain (NeuP) are available, but its treatment remains unsatisfactory. We systematically summarized evidence from systematic reviews (SRs) of randomized controlled trials on interventions for NeuP. Five electronic databases were searched up to March 2015. Study quality was analyzed using A Measurement Tool to Assess Systematic Reviews. The most common interventions in 97 included SRs were pharmacologic (59%) and surgical (15%). The majority of analyzed SRs were of medium quality...

OBJECTIVE: The central mechanisms underlying postherpetic neuralgia (PHN) pain remains unknown. The primary purpose of this study was to identify microstructural white matter changes closely related to the PHN pain by means of diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS) analysis. METHODS: DTI data of the brains were obtained from 8 PHN patients and 8 healthy controls (HC) that were matched in age, gender, and educational level. DTI metrics, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD), were separately compared between the two groups using TBSS analysis to detect subtle microstructural changes...

BACKGROUND: Herpes zoster (HZ) can develop into postherpetic neuralgia (PHN), both of which are painful diseases. PHN patients suffer chronic pain and emotional disorders. Previous studies showed that the PHN brain displayed abnormal activity and structural change, but the difference in brain activity between HZ and PHN is still not known. OBJECTIVES: To identify regional brain activity changes in HZ and PHN brains with resting-state functional magnetic resonance imaging (rs-fMRI) technique, and to observe the differences between HZ and PHN patients...

BACKGROUND: In a 5-year follow-up study in a hospital in southern China, it was shown that intervertebral foramen (IVF) injection of ozone at the involved segmental levels could significantly alleviate paroxysmal spontaneous pain and mechanical allodynia in patients with chronic, intractable postherpetic neuralgia (PHN) and improve the quality of life. However, so far no proof-of-concept studies in animals have been available. OBJECTIVE: This study was designed to investigate whether IVF ozone has an analgesic effect on animal models of neuropathic and inflammatory pain...

BACKGROUND: Postherpetic neuralgia (PHN) is a refractory condition that impairs the patient's quality of life (QoL), it develops secondary to herpes zoster infection. Therefore, it's important to prevent the transition of acute/subacute zoster-related pain to PHN. Despite of numerous studies, the optimal intervention that reduces PHN incidence is still unknown. OBJECTIVE: We evaluate the efficacy of short-term spinal cord stimulation (stSCS) in patients with refractory acute/subacute zoster-related pain...

BACKGROUND: Herpes zoster (HZ) is associated with inflammation of the peripheral nerves, which is considered to be an important cause of postherpetic neuralgia (PHN). Interventions aimed at reducing this inflammation could prevent PHN. One option is the epidural administration of corticosteroid and local anesthetic. However, several authors have reported a risk of arachnoiditis with epidural corticosteroids. Subcutaneous injection in an outpatient setting is a safer option. However, there is limited evidence of the effectiveness of this alternative for preventing PHN...

Background Calpain is a calcium-dependent cysteine protease, and inhibition of calpain by pre-treatment with MDL28170 attenuated the rat mechanical allodynia in a variety of pain models. Postherpetic neuralgia (Shingles) is a neuropathic pain conditioned with the presence of profound mechanical allodynia. Systemic injection of resiniferatoxin can reproduce the clinical symptoms of postherpetic neuralgia. In this study, we determined to study whether activation of calpain contributes to cleave the myelin basic protein of dorsal root and is involved in resiniferatoxin-induced mechanical allodynia of postherpetic neuralgia animal model...

Post-herpetic neuralgia (PHN) is a complication of herpes zoster that can cause different types of pain in the affected area. It often occurs mainly in severe cases of herpes zoster. The problem is defined as a persisting pain for 90-120 days after relieving of acute phase of herpes lesions. This complication causes suffering in patients and reduces the quality of life. In western medicine's viewpoints, PHN is due to disturbance in local and dermatomal nerves. There are several topical and systemic drugs that are used to manage the pain relief...

Ramsay Hunt syndrome (herpes zoster oticus) is a rare complication of latent Varicella Zoster virus infection. It can be complicated by permanent hearing loss, loss of taste and postherpetic neuralgia. Although Ramsay Hunt syndrome most prominently involves the facial nerve, a number of other cranial nerves can be involved such as the vestibulocochlear, glossopharyngeal and the vagus nerve. We report on a case of Ramsay Hunt syndrome with cranial polyneuritis complicated by atrial fibrillation. Vagal involvement as evidenced by physical examination and MRI findings was present in our patient...

Herpes zoster along the maxillary division of the trigeminal nerve is a rare condition that is caused by reactivation of the varicella zoster virus that resides within the trigeminal ganglion after the primary infection of chickenpox. The disease may be manifested as a toothache during its prodromal stage. The active stage of the disease is characterized by the appearance of a vesicular rash. Postherpetic neuralgia is a common complication of herpes zoster after resolution of the facial and intraoral symptoms...

Delusional parasitosis (DP) or Ekbom's disease is a rare psychiatric condition where the sufferers have a firm-fixed belief of insects crawling over their skin. The condition may be primary monosymptomatic hypochrondrical delusion or secondary to an underlying psychiatric or organic condition. We present two cases of elderly men presenting with classical symptomatology of DP, which is found to be secondary to postherpetic neuralgia following an acute episode of shingles or herpes zoster infection. One patient responded to a combination of antipsychotic, olanzapine, and pregabalin, used for neuropathic pain, and the other patient responded completely with medications used for neuropathic pain only without any antipsychotic use...

BACKGROUND: Neuropathic pain (NP) (including painful diabetic neuropathy, postherpetic neuralgia, etc) affects approximately 7% to 8% of the population and is associated with a devastating symptom burden as well as a profound economic impact for patients, their families, and the health care system. Current therapies have limited efficacy and dose-limiting adverse effects (AEs). Rational combination therapy with carefully selected NP drugs has shown potential for measurable improvements in pain relief, quality of life, and health care use...

In a recent cluster analysis, it has been shown that patients with peripheral neuropathic pain can be grouped into 3 sensory phenotypes based on quantitative sensory testing profiles, which are mainly characterized by either sensory loss, intact sensory function and mild thermal hyperalgesia and/or allodynia, or loss of thermal detection and mild mechanical hyperalgesia and/or allodynia. Here, we present an algorithm for allocation of individual patients to these subgroups. The algorithm is nondeterministic-ie, a patient can be sorted to more than one phenotype-and can separate patients with neuropathic pain from healthy subjects (sensitivity: 78%, specificity: 94%)...
