Regional-anaesthesiological Infiltration Techniques for the Management of Chronic Pain: a Retrospective...

Chronic PainTrigeminal Neuralgia4 more

There is a significant debate whether local infiltration techniques may be a method to treat complicated chronic pain syndromes, e.g. refractory headache. Until now there is a lack of evidence regarding efficacy of this treatment especially in long term follow up. Similarly, indication and management are under debate. Aim of this trial is to analyse pain scores during first treatment with anaesthesiological infiltration series.

Effects of Pennsaid on Clinical Neuropathic Pain

NeuralgiaPostherpetic Neuralgia2 more

The purpose of this study is to see if the drug Pennsaid (Diclofenac) can help reduce pain felt by people with chronic nerve pain. The drug will be used 2-4 times each day for 2 weeks. The U.S. Food and Drug Administration (FDA) has approved Pennsaid to treat osteoarthritis (bone pain), but the FDA has not approved Pennsaid to treat neuropathic (nerve) pain. The research study will compare Pennsaid to placebo.

Association of Transcutaneous Electrical Nerve Stimulation and Hypnosis

Limbs ArthrosisNon Arthrosic Limbs Arthralgia8 more

At Saint-Antoine's hospital, in CETD a multidisciplinary team takes care of patients with chronic pain. Free-drug techniques are available to reduce their consumption of analgesics. This study is to assess the relief obtained by the simultaneous combination of these two techniques: transcutaneous electrical nerve stimulation and hypnosis.

Study of Possible Changes in QST After Application of Capsaicin on Patients With Peripheral Neuropathic...

Peripheral Nerve InjuryPostherpetic Neuralgia

The treatment of neuropathic pain ist still a challenge. A new promising therapy is the use of capsaicin on skin. The investigators first experiences with capsaicin in patients with peripheral nerve injury showed changes in the sensibility, which achieved its maximal extent after four weeks and was regressive, but not completely abolished 1,5 months after application. In this study the investigators hope to specify, how long and in which way exactly this changes in sensibility appear.

Effect of Opioids in Neuropathic Pain in Postherpetic Patients

NeuralgiaPostherpetic

Postherpetic neuralgia (PHN) is often associated with pain and sensory changes and is the leading type of neuropathic pain in modern clinical pain research. It is characterized by a variety of sensory patterns, which may be categorized into "irritable nociceptor" and "impairment of nociceptor". At date, several lines of evidence lead to the assumption, that mechanical hyperalgesia in PHN is based - at least in part - on central nervous processes of sensitization. In animal studies the investigators have discovered a previously unrecognized effect of opioids, the reversal of long-term potentiation (LTP) at C-fibre synapses, i.e. an opioid-induced depotentiation. In principle, synaptic depotentiation may be permanent or transient. In our study the clinically used ultra-short acting MOR agonist remifentanil normalized synaptic strength after wash-out of the drug. At present it is not known whether opioid-induced depotentiation can be used to the benefit of pain patients. The aim is to study the hypothesis, that pain in a group of PHN patients with predominant mechanical hyperalgesia is reversed by intravenous remifentanil at a plasma target concentration of 18ng/ml (corresponding to about 0.75 µg/kg/min) for 60 minutes compared with PHN patients of other sensory types.

Prevention of Post Herpetic Neuralgia by Ultrasound Guided Single Nerve Block in the ED

Pain

Herpes zoster causes significant morbidity on over 1 million Americans every year. Although the majority of herpes zoster pain will self-resolve within one week, a significant proportion of patients will develop postherpetic neuralgia (PHN), which is characterized by debilitating pain that persists more than three months after the initial symptoms. Nerve blocks have been previously studied as a method to control herpes zoster pain in outpatient pain clinics and inpatient settings. This study aims to investigate whether emergency department ultrasound guided nerve blocks can prevent PHN and effectively treat acute herpes zoster pain.

The Evaluation of Erector Spinae Plane Block for the Pain Control of Thoracic Postherpetic Neuralgia...

Thoracic Postherpetic Neuralgia

Erector spinae plane block is new interfascial plane block, and can be applied to management of thoracic neuropathic pain syndromes. The target of needle is deeper(or anterior) to the erector spinae muscle. So it is more safe and simple technique than prior technique, thoracic paravertebral block. The aim of this study is the evaluation of erector spinae plane block comparison to prevertebra block.

Single Nucleotide Polymorphisms (SNPs) Associated With Postherpetic Neuralgia

Postherpetic Neuralgia

Postherpetic neuralgia (PHN) is a common condition and affecting 5 to 30% of the herpes zoster patients. In some cases, the pain remained refractory after first and second line treatment for herpes zoster. This suggests that there may be genetic variants that make some patients susceptible to PHN. Using saliva samples from herpes zoster patients the investigators are going to analyze the relationship between single nucleotide polymorphisms (SNPs) in genes that are known to be involved in pain and PHN.
