Pain is a major problem for chronic pancreatitis (CP) patients. Unfortunately, medical therapy often fails. Endoscopic and surgical treatments are invasive, and results vary. Percutaneous radiofrequency ablation of the splanchnic nerves (RFSN) is a relatively new and minimally invasive procedure for treatment of intractable pain in CP patients. ⋯ Radiofrequency ablation of the splanchnic nerves is a minimally invasive, effective procedure for pain relief. After the effect has subsided, RFSN can be successfully repeated. RFSN might become an alternative treatment in a selected group of CP patients. A larger, randomized trial is justified to substantiate these findings.

There is convincing evidence that inflammation plays a pivotal role in the pathophysiology of complex regional pain syndrome (CRPS). Besides inflammation, central sensitization is also an important phenomenon. ⋯ In the development of a more mechanism-based treatment, influencing the activity of mast cells might be important in the treatment of CRPS. We describe the rationale for using medication that counteracts the effects of mast cells in the treatment of CRPS.

Cytokines and oxygen free radicals have been implicated in the potential pathogenic development of complex regional pain syndrome (CRPS). We aimed to analyze the relationship between clinical status, circulating levels of cytokines, and markers of oxidative damage during the treatment with anti-TNFα antibodies. The patient chosen for treatment had not had improvement through a number of conventional therapies and fulfilled the current diagnostic criteria for CRPS-1. ⋯ Although the patient showed an improvement of the cutaneous dystrophic symptoms and diminished pain associated with these lesions, the levels of circulating TNFα increased after the administration of anti-TNFα antibodies. In a patient with CRPS-1 treated with anti-TNFα antibodies, we report increased levels of circulating TNFα and a temporary mitigation of oxidative stress as measured by plasma F2 -isoprostane. This case report provides evidence 2 supporting the indication of monitoring the oxidative stress biomarkers during treatment with anti-TNFα antibodies in CRPS 1.

Clinical Trial
Anti tumor Necrosis Factor - Alpha Adalimumab for Complex Regional Pain Syndrome Type 1 (CRPS-I): A Case Series.
Evidence suggests tumor necrosis factor-alpha (TNF-α) mediates, at least in part, symptoms and signs in complex regional pain syndrome (CRPS). Here, we present a case series of patients with CRPS type 1, in whom the response to the anti-TNF-α adalimumab was assessed. ⋯ These results suggest adalimumab, and possibly other anti-TNF-α, can be potentially useful in some (although not in all) patients with CRPS type 1. These preliminary results along with the growing body of evidence which points to the involvement of TNF-α in the pathogenesis of CRPS justify further studies in this area.

Burning mouth syndrome (BMS) is a chronic condition most common in middle-aged and elderly women, with prevalence rates in the general population ranging from 0.5% to 5%. Defined by the International Headache Society as "an intraoral burning sensation for which no medical or dental cause can be found," BMS is considered a form of neuropathic pain. The management of BMS remains unsatisfactory. ⋯ Acupuncture treatment lasted 8 weeks and consisted of 20 sessions. Patients reported a mean reduction in pain of 0.99 points on the VAS (max 2.1-min 0.1), which, although slight, was statistically significant (Wilcoxon test P < 0.009). No significant improvement in the overall score for quality of life was observed, although subjects receiving acupuncture treatment seemed better able cope with their oral symptoms.
