Altered pain sensations such as hyperalgesia and allodynia are characteristic features of various pain states, and remain difficult to treat. We have shown previously that spinal application of dipeptidyl peptidase 4 (DPP4) inhibitors induces strong antihyperalgesic effect during inflammatory pain. In this study we observed low level of DPP4 mRNA in the rat spinal dorsal horn in physiological conditions, which did not change significantly either in carrageenan-induced inflammatory or partial nerve ligation-generated neuropathic states...

STUDY DESIGN: Reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistological analysis of spinal cord and pain behavior analysis in a rat neuropathic pain model were conducted to examine the function of microglial basic fibroblast growth factor (bFGF) in the development of neuropathic pain. OBJECTIVE: To investigate the role of bFGF in spinal microglia during the development of allodynia following spinal nerve ligation in rats. SUMMARY OF BACKGROUND DATA: Evidence suggests that the production of bFGF by spinal cord glial cells is increased in response to peripheral nerve injury...

Postpartum pain is a frequent condition that negatively affects women's quality of life, interferring with everyday life. Analgesic drugs and surgery are often contraindicated in pregnancy and during breast feeding. This review of the literature aims to evaluate the rational of the association of lipoic acid and omega-3 employ in the management of postpartum pain. Lipoic acid is a cofactor essential in mitochondrial metabolism with antioxidant and anti-inflammatory activity. Lipoic acid has been shown to be effective in neuropatic pain treatment in patients with sciatica, carpal tunnel syndrome and diabetic neuropathy...

UNLABELLED: The study explored the analgesic effects of transcranial direct current stimulation (tDCS) over the motor cortex on postamputation phantom limb pain (PLP). Eight subjects with unilateral lower or upper limb amputation and chronic PLP were enrolled in a crossover, double-blind, sham-controlled treatment program. For 5 consecutive days, anodal (active or sham) tDCS was applied over the motor cortex for 15 minutes at an intensity of 1.5 mA. The 5-day treatment with active, but not sham, tDCS induced a sustained decrease in background PLP and in the frequency of PLP paroxysms, which lasted for 1 week after the end of treatment...

BACKGROUND: Neuropathic pain induced by spinal or peripheral nerve injury is very resistant to common pain killers, nerve block, and other pain management approaches. Recently, several studies using stem cells suggested a new way to control the neuropatic pain. In this study, we used the spinal nerve L5 ligation (SNL) model to investigate whether intrathecal rat mesenchymal stem cells (rMSCs) were able to decrease pain behavior, as well as the relationship between rMSCs and reactive oxygen species (ROS)...

PURPOSE: This study was designed to evaluate the antihyperalgesic effect of CDP-choline (cytidine-5'-diphosphate- choline; citicoline) in a rat model of neuropathic pain produced by oxaliplatin (OXA). METHODS: A single administration of OXA (6 mg/kg intraperitoneally/ ip) was used for induction of neuropathy. We assessed the antihyperalgesic effect of intracerebroventricularly (icv) administered CDP-choline (0.5, 1.0 and 2.0 μmol) using the rat paw pressure test (Randall-Selitto)...

The purpose of this study was to evaluate the effectiveness and middle-term durability of the results achieved with perineural fat grafting of painful neuromas of the upper limb. We retrospectively analysed eight patients, affected by eight neuromas, treated by neuroma excision and fat grafting around the proximal nerve stump. Clinical parameters, the disabilities of the arm shoulder and hand score, and the visual analogue scale were recorded at 2, 6 and 12 months after surgery. A reduction of 23.2% was observed in the mean disabilities of the arm shoulder and hand scores at 12 months...

Treatment of painful neuromas of the upper limb has been largely debated. The current surgical treatments spare from simple neuroma excision to proximal nerve stump relocation (into muscles, veins, and bones). Perineural fat grafting consists of neuroma excision and the creation of an autologous adipose graft wrapped around the proximal nerve stump. This technique should be prescribed to those patients suffering from terminal neuromas or neuromas in which functional reconstruction is contraindicated. The effectiveness of this technique could be addressed both to the mechanical and biological properties of the fat graft...

Pain management for a patient in palliative care requires a multi-functional approach that entails the physical, psychological, social and spiritual dimensions. It is based on a deep understanding of the pain physiopatology and its accurate assessment to optimize the treatment. This article provides guidelines to manage nociceptive and neuropathic pains, along with tips in case of refractory pains. It gives detailed instructions relative to the use of strong opiods taking advantage of the availability of new types of galenics...

Chronic pelvic pain (CPP), defined as non-cyclic pain of 6 or more months, is a frequent disorder that may negatively affect health-related quality of life. In women several causes are recognised, although in a not negligible proportion of patients a definite diagnosis cannot be made. Different neurophysiological mechanisms are involved in the pathophysiology of CPP. Pain may be classified as nociceptive or non-nociceptive. In the first case the symptom originates from stimulation of a pain-sensitive structure, whereas in the second pain is considered neuropatic or psychogenic...

Gaucher disease is the most common lysosomal storage disorder. Incidence of disease is around 1:40-60,000 inhabitants and it is assuming that in Croatia we have 20-30 patients with Morbus Gaucher. Morbus Gaucher is recognized in three types. Type I or so called non-neuropatic from is most common in Europe while so called neuropatic forms (type II and III) are much rare (5-10%). Type II and III are characterized by central nervous system involvement and usually are diagnosed in childhood. Disease manifestations are observed in various human organs...

OBJECTIVE: In present study we analyze the causes leading to reoperation patients treated for lumbar spinal stenosis with laminectomy and lumbar instrumentation. MATERIAL AND METHODS: 74 patients operated between January of 1996 and December of 2000 with a minimum 4 year follow-up were seleted for the study. RESULTS: 16 patients (21.1%) underwent a new surgical intervention. The main cause for reoperation was stenosis of the adjacent level superiorly to the instrumentation (in 50%)...

Bortezomib is a novel proteasome inhibitor with significant antimyeloma activity. Its toxicity is manageable, and the most frequent adverse effects mainly consist of gastrointestinal symptoms, peripheral neuropathy, neuropatic pain, and thrombocytopenia. Severe liver toxicity has not been previously recognized. A patient with relapsed multiple myeloma who developed bortezomib-induced severe recurrent hepatitis is described. The importance of recognizing this rare potential toxicity is highlighted in order to discontinue this agent if liver adverse reaction is suspected...

Headache, facial pain and toothache are poorly localized and irradiate in distant areas. Thus, toothache often causes facial pain and headache, but, in turn, it can also be mimicked by several forms of these disorders, in particular by a myoarthropathy of the masticatory system, a migraine, a tension-type headache, a neuropatic pain and a trigeminal neuralgia. The atypical odontalgia is a nonodontogenic form of toothache that is difficult to diagnose; therefore, it leads to a number of invasive dental procedures which normally worsen the pain condition...
