Neuropathic Pain

The Neuropathic Pain Knowledge Centre is a unique resource containing a wealth of current information in this field of medicine.

The nervous system (central and peripheral) constantly receives and interprets information about the body's surroundings and the body's own functioning, responding by sending out messages to tissues and organs.

The Knowledge Centre addresses the two types of pain: nociceptive and clinical. Nocicpetive pain aims to protect individuals from harm. Clinical pain results from damage or inflammation of a part of the body and consists of both spontaneous pain that may arise with no apparent peripheral stimulus, and from hypersensitivity to peripheral stimuli1 due to peripheral and central sensitisations.

Neuropathic pain is often described as a shooting, stabbing or burning sensation. Estimates suggest that neuropathic pain may affect as much as 3% of the population.

Different types of neuropathic pain exist depending on their origin, details of which can be found in the Knowledge Centre: Painful Diabetic Neuropathy, Herpes Zoster and Post-Herpetic Neuralgia (PHN), HIV Associated-Neuropathy (HIV-AN), Cancer-related Neuropathic Pain, Post-surgical/Post-traumatic Neuropathic Pain.

In the clinic, the diagnosis of neuropathic pain relies on an accurate history and examination and some pain evaluation tools are used.

As Neuropathic pain doesn't respond to conventional therapy with analgesics, the different treatment regimens are antidepressants, anticonvulsants, opioids, topical agents and combination treatment.

To help physicians in the pharmacological management of this condition, recent guidelines are available.

Clinical Guidelines

Guidelines on Penile Cancer

Apr 2014

The European Association of Urology (EAU) Guidelines Group on Penile Cancer has prepared this..

... guidelines document to assist medical professionals in the management of penile cancer. The guidelines aim to provide detailed, up-to-date information, based on recent developments in our understanding and management of penile squamous cell carcinoma (SCC). However, it must be emphasised that these guidelines provide an updated, but not yet standardised general approach to treatment and that they provide guidance and recommendations without legal implications.

Impact of Physical Activity and Vitamin D on Osteoarthritic Knee Pain

13-11-2014

Knee Osteoarthritis (KOA) is a major cause of pain and disability, particularly in those of increasing age and body fat. As there are no very effective therapies for KOA, disease often progresses until knee replacement surgery is needed. It has been..

... observed Vitamin D and Physical Activity (PA) levels are lower in those with KOA, increased age and body fat. As the relationship between KOA, Vitamin D and PA levels are not clearly understood, this study aims to explore these relationships and the acceptability/feasibility of PA and Vitamin D interventions in those who would likely to benefit from these interventions.

200-300 people, 50-70 years, BMI 30-40kg/m2, meeting American College of Rheumatology (ACR) KOA Guidelines, will be recruited from North Tyneside and Liverpool Hospital trusts November 2014-January 2016 to participate in a single cross-sectional study visit, which will measure: Vitamin D/Calcium serum levels, BMI/Body Fat, mobility, Quality of life and pain (by questionnaire), and PA levels.

Those participants with insufficient Vitamin D levels (25-50nmol/L) and PA levels (<30min moderate PA/week), will be invited to take part in a 3 month pilot RCT study.

>64 people will be recruited for the pilot RCT and equally randomly allocated to 1 of 4 intervention groups: Vitamin D (1 capsule a day: 2000IU), Placebo (identical capsule: 1 a day), PA (online PA programme) and PA and Vitamin D. Additionally at the end of the 12 week study visit, up to 20 participants will be invited to take part in a qualitative interview exploring their experience during the two studies.
