Comparative Study
Pulsed and conventional radiofrequency treatment: which is effective for dental procedure-related symptomatic trigeminal neuralgia?
Many patients develop dental treatment-related symptomatic trigeminal neuralgia. However, the effectiveness of pulsed radiofrequency (PRF) treatment and conventional radiofrequency thermocoagulation (RFTC) for treatment of this disorder has not been determined. This retrospective study was conducted to compare the effectiveness and complications of PRF and RFTC in these patients. ⋯ Although the RFTC group had more complications than the PRF group, most were minor and transient, and the patient satisfaction rate with RFTC was very high. Therefore, RFTC is an effective tool for the treatment of dental procedure-induced trigeminal neuralgia.

Randomized Controlled Trial Multicenter Study
A randomized, placebo-controlled trial of transdiscal radiofrequency, biacuplasty for treatment of discogenic lower back pain.
The aim was to compare the efficacy of intradiscal biacuplasty (IDB) with that of placebo treatment for discogenic low back pain. ⋯ The results suggest that the clinical benefits observed in this study are the result of non-placebo treatment effects afforded by IDB. IDB should be recommended to select the patients with chronic discogenic low back pain. (Clinicaltrials.gov number, NCT00750191.).

Burning mouth syndrome (BMS) is characterized by the following subjective complaints without distinct organic changes: burning sensation in mouth or chronic pain of tongue. BMS is also known as glossodynia; both terms are used equivalently in Japan. Although the real cause of BMS is still unknown, it has been pointed out that BMS is related to some autonomic abnormality, and that stellate ganglion near-infrared irradiation (SGR) corrects the autonomic abnormality. Frequency analysis of heart rate variability (HRV) is expected to be useful for assessing autonomic abnormality. ⋯ Frequency analysis of HRV revealed the autonomic instability associated with BMS and enabled tracing of autonomic changes corrected with SGR. It is suggested that frequency analysis of HRV is very useful in follow up of BMS and for determination of the therapeutic efficacy of SGR.

OBJECTIVES.: The objectives of this study were to (1) compare the prevalence of smoking within chronic pain patients (CPPs) to community non-patients without pain (CNPWP), community patients with pain (CPWP), and acute pain patients (APPs); and (2) compare smokers to nonsmokers within CPPs, APPs, and CPWP for highest pain level. DESIGN.: CNPWP, CPWP, APPs, and CPPs were compared to each other for smoking status (nonsmoker, less than one pack per day, one pack/day or more, any amount per day). Within CPWP, APPs, and CPPs, smokers were also compared to nonsmokers by t-test for highest reported pain level. ⋯ CPP smokers were not significantly more likely than nonsmokers to have higher pain, and this was confirmed in the sub-analyses. CONCLUSIONS.: The prevalence of smokers could be significantly greater within CPPs vs CPWP. CPPs who smoke do not have higher levels of pain than nonsmoking CPPs.
