The effectiveness of acupuncture for chronic pain with depression: A systematic review protocol

Association between signs of hyperalgesia and reported frequent pain in jaw-face and head

OBJECTIVE

To analyze the relationship between different sites of elicited pain to muscle palpation (PtP), and reported frequent pain in jaw-face and head.

MATERIALS AND METHODS

The analysis was based on an epidemiological sample of 1200 randomly selected individuals, of which 779 (65%) both completed a questionnaire and participated in a clinical examination. The questionnaire addressed the presence of pain in the jaw-face region and headache, respectively. Part of the clinical examination entailed palpation of the jaw, neck, shoulder, arm, thumb and calf muscles. Logistic regression was applied with pain and headache as dependent variables. A p-value < .05 determined statistical significance.

RESULTS

Five percent of participants reported frequent pain in jaw-face, and 17% reported frequent headaches. In the regression analysis, frequent headaches were significantly associated with jaw muscle PtP (OR 2.1, CI 1.4-3.4), regional PtP (OR 4.5, CI 2.6-7.6), and generalized PtP (OR 6.1, CI 2.2-17.0). Jaw-face pain was significantly associated with regional PtP (OR 5.3, CI 2.2-13.0) and generalized PtP (OR 30.1, CI 9.3-97.0). The relationship between pain prevalence and PtP showed a dose-response pattern.

CONCLUSIONS

The study indicates that frequent jaw-face pain and headache are primarily associated with signs of regional and widespread hyperalgesia, which may be linked to the central sensitization mechanism. Signs of widespread hyperalgesia should be accounted for in the diagnostic algorithms when examining patients with pain in the jaw, face, and head regions.

Non-Opioid Perioperative Pain Strategies for the Clinician: A Narrative Review

Alternative and non-opioid options for pain management are necessary in perioperative patient care. Opioids are no longer touted as cure-all medications, and furthermore, there have been tremendous advances in alternative therapies such as in interventional pain, physical therapy, exercise, and nutritional counseling that have proven benefits to combat pain. The center for disease control now strongly recommends the use of multimodal analgesia and multidisciplinary approaches based on the individual needs of patients: personalized medicine. In this manuscript, the specifics of non-opioid pharmacological and non-pharmacological analgesic approaches will be discussed as well as their possible indications and uses to reduce the need for excessive use of opioids for adequate pain control.

Long-Term Beneficial Effects of Acupuncture with Reduced Risk of Depression Development Following Trigeminal Neuralgia: A Nationwide Population-Based Cohort Study

BACKGROUND

Existing evidence has shown that patients with trigeminal neuralgia (TN) have a higher risk of developing depression than the normal population. Clinically, acupuncture has been widely used to alleviate pain in TN. However, few studies have explored the use of acupuncture to prevent depression in TN. Therefore, this study aimed to apply national real-world data to investigate the long-term effect of acupuncture on the risk of depression in patients with TN.

METHODS

We recruited participants with newly diagnosed TN from the Taiwanese National Health Insurance Research Database between January 1, 2000 and December 31, 2010, and categorized them into either the acupuncture cohort or non-acupuncture cohort using the 1:1 propensity score-matched method. All patients in the two cohorts were followed up until the end of 2013. Cox proportional hazards regression analysis was used to compare the incidence of depression between the two cohorts.

RESULTS

In total, 776 patients with newly diagnosed TN in each cohort with similar baseline characteristics were enrolled in the study. The acupuncture cohort had a reduced risk of depression compared to the non-acupuncture cohort (adjusted hazard ratio, 0.47; 95% confidence interval, 0.31-0.70). Kaplan-Meier analysis also revealed that the cumulative incidence of depression was significantly lower in the acupuncture cohort during the 13-year follow-up period (Log rank test, p < 0.001). In particular, the beneficial effect of acupuncture was a decrease in the risk of depression among TN patients aged 50-69 years who had also used carbamazepine.

CONCLUSION

This study demonstrated that acupuncture is associated with a reduction in the risk of depression during long-term follow-up in patients with TN. The results provide new insights for clinical practitioners as well as for health resource allocation.

F-Shaped Osteotomy Combined with Basal Opening Wedge Osteotomy for Severe Hallux Valgus

Objective

To evaluate the safety and effectiveness of osteotomy adjacent to the articular surface of the metatarsal head combined with basal opening wedge osteotomy for severe hallux valgus.

Methods

The double osteotomy procedure was carried out in 56 patients (72 feet) with severe hallux valgus deformity, with an average follow‐up of 25 months from March 2010 to February 2019. Hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), intermetatarsal angle (IMA), and distal articular set angle (DASA) were measured for all patients via weight‐bearing anteroposterior (AP) X‐ray images. In addition, the American Orthopedic Foot & Ankle Society (AOFAS) scale was used for evaluating the function of the hallux.

Results

The HVA, IMA, and DMAA reduced from 49.30 ± 6.60, 19.33 ± 4.70, and 29.85 ± 10.96 to 13.19 ± 6.10, 5.97 ± 3.13, and 5.63 ± 3.44, respectively (P < 0.01). DASA decreased from 4.33 ± 2.34 to 4.08 ± 1.91 and did not show a statistically significant difference (P = 0.48). Among the 72 feet, 69 feet healed normally, and 3 feet had bone resorption at the osteotomy edges. No cases of bone sclerosis, bone necrosis, bone nonunion, or ankylosis were observed. On average, the AOFAS score improved from 34.66 ± 12.07 (preoperative) to 88.78 ± 5.73 (postoperative).

Conclusions

The proposed double osteotomy procedure can maintain the match metatarsophalangeal joints without ischemic necrosis of bones, and is demonstrated to be safe, effective, and feasible for correcting severe hallux valgus.

Alleviation of trigeminal neuropathic pain by electroacupuncture: the role of hyperpolarization-activated cyclic nucleotide-gated channel protein expression in the Gasserian ganglion

INTRODUCTION

The aim of this study was to examine the effect of electroacupuncture (EA) on trigeminal neuropathic pain in rats and explore the potential mechanism underlying the putative therapeutic effect of EA.

METHODS

Trigeminal neuropathic pain behavior was induced in rats by unilateral chronic constriction injury of the distal infraorbital nerve (dIoN-CCI). EA was administered at ST2 (Sibai) and Jiachengjiang. A total of 60 Sprague Dawley rats were divided into the following four groups (n = 15 per group) to examine the behavioral outcomes after surgery and/or EA treatment: sham (no ligation); dIoN-CCI (received isoflurane only, without EA treatment); dIoN-CCI+EA-7d (received EA treatment for 7 days); and dIoN-CCI+EA-14d (received EA treatment for 14 days). Both evoked and spontaneous nociceptive behaviors were measured. Of these, 12 rats (n = 4 from sham, dIoN-CCI, and dIoN-CCI+EA-14d groups, respectively) were used to analyze protein expression of hyperpolarization-activated cyclic nucleotide-gated (HCN) channel in the Gasserian ganglion (GG) by immunohistochemistry.

RESULTS

dIoN-CCI rats exhibited mechanical allodynia and increased face-grooming activity that lasted at least 35 days. EA treatment reduced mechanical allodynia and face-grooming in dIoN-CCI rats. Overall, 14 days of EA treatment produced a prolonged anti-nociceptive effect as compared to 7-day EA treatment. The counts of HCN1 and HCN2 immunopositive puncta were increased in the ipsilateral GG in dIoN-CCI rats and were reduced by 14 days of EA treatment.

DISCUSSION

EA treatment relieved trigeminal neuropathic pain in dIoN-CCI rats, and this effect was dependent on the duration of EA treatment. The downregulation of HCN expression may contribute to the anti-nociceptive effect of EA in this rat model of trigeminal neuropathic pain.
