Ashi Acupuncture Versus Local Anesthetic Trigger Point Injections in the Treatment of Abdominal Myofascial Pain Syndrome: A Randomized Clinical Trial.

BACKGROUND: Chronic pelvic pain (CPP) is defined as recurrent or continuous pain in the lower abdomen or pelvis, non-menstrual or non-cyclic, lasting at least 6 months. There is strong evidence that up to 85% of patients with CPP have serious dysfunction of the musculoskeletal system, including abdominal myofascial syndrome (AMPS). AMPS is characterized as deep abdominal pain, originating from hyperirritable trigger points, usually located within a musculoskeletal range or its fascia of coating. In the literature, there are few studies that address AMPS. OBJECTIVE: This study aimed to compare the responses of ashi acupuncture treatment and local anesthetic injection in the treatment of chronic pelvic pain secondary to abdominal myofascial pain syndrome in women. STUDY DESIGN: Randomized controlled clinical trial. SETTING: Tertiary University Hospital. METHODS: Women with a clinical diagnosis of CPP secondary to AMPS were randomized and evaluated using instruments to assess clinical pain, namely, the visual analogue scale (VAS), numerical categorial scale (NCS), and the McGill Questionnaire, after receiving treatment with ashi acupuncture (group A, n = 16) or local anesthetic injections (group B, n = 19). They were reevaluated after one week and one, 3, and 6 months after each treatment, in addition to assessments of pain and adverse events performed during the sessions. RESULTS: Ashi acupuncture and local anesthetic injections were both effective in reducing clinical pain assessed through the analyzed variables among study participants. There was no difference between the groups and there was a strong correlation between these pain assessment instruments. LIMITATIONS: The absence of blinding to the different forms of treatment among the patients and the researcher directly involved in the treatment, the absence of a placebo group, the selective exclusion of women with comorbidities and other causes of CPP, and the difference between the number of sessions used for each technique. CONCLUSION: Treatments with ashi acupuncture and local anesthetic injections were effective in reducing clinical pain in women with abdominal myofascial pain syndrome.

Effect of Acupuncture on Chronic Pelvic Pain Secondary to Abdominal Myofascial Syndrome Not Responsive to Local Anesthetic Block: A Pilot Study.

Objective: Strong evidence shows that 85% of women with chronic pelvic pain (CPP) have musculoskeletal disorders, such as abdominal myofascial pain syndrome (AMPS). The aim of this research was to assess the efficacy of local acupuncture treatment for women with CPP secondary to AMPS unresponsive to treatment with trigger-point injection. Materials and Methods: This pilot study involved 17 women with moderate-to-severe AMPS-related CPP. Acupuncture treatments were given at abdominal-wall trigger points once per week for 10 consecutive weeks. Pain relief was assessed with a visual analogue scale (VAS), the McGill questionnaire, and pressure dynamometer. Quality of life and psychosocial function (risk for anxiety and depression) were evaluated using the Short-Form-36 questionnaire and the Hospital Anxiety and Depression scale. Assessments were performed at baseline and after 1, 3, and 6 months of treatment. Results: Both the VAS and McGill pain questionnaire showed significantly decreased pain intensity (VAS, P < 0.001; and McGill, P 0.049), and the effects were sustained even at 6 months after treatment. Conclusions: Acupuncture treatment was effective for the women who participated in this study, and the current authors believe that these preliminary results suffice to recommend performing randomized controlled trials.

Reduction of Pain Sensitivity is Associated with the Response to Treatment in Women with Chronic Pelvic Pain.

OBJECTIVE: The objective of this study was to evaluate whether pain thresholds to electrical stimulation of the skin change in the response to treatment in women with chronic pelvic pain (CPP). METHODS: Fifty-eight women with persistent pelvic pain for at least 6 months, from a tertiary care setting, were included in this study. All women were evaluated before the therapeutic intervention and at 6 months of multidisciplinary treatment. To estimate the pain threshold, we used transcutaneous electrical nerve stimulation on the anterior surface of the nondominant arm. The intensity of clinical pain was estimated by a visual analog scale and by the McGill questionnaire. RESULTS: The mean of pain threshold increased from 14.2 to 17.4 after 6 months of treatment (P < 0.0001). The effect sizes of the increase of electrical pain threshold were 0.86 (95% CI, 0.38 to 1.34) in the group with pain reduction and 0.53 (95% CI, -0.08 to 1.15) in the group without pain reduction. CONCLUSION: The sensitivity to experimental pain was reduced after 6 months of multidisciplinary treatment for CPP. Our data provided additional evidence of central sensitization in women with CPP.

Thiele massage as a therapeutic option for women with chronic pelvic pain caused by tenderness of pelvic floor muscles.

AIMS AND OBJECTIVES: Musculoskeletal system has been found to be involved in genesis and perpetuation of chronic pelvic pain (CPP) and has strong evidences that up to 80% of women with CPP present dysfunction of the musculoskeletal system. In this study, we report a series of women with CPP caused by tenderness of pelvic floor muscles successfully treated with Thiele massage. METHODS: Were included in this study six women with CPP caused by tenderness of the levator ani muscle that underwent transvaginal massage using the Thiele technique, over a period of 5 minutes repeated once a week for 4 weeks. After 1 month, the women returned for follow-up. RESULTS: The median tenderness score for the six women evaluated was 3 at the first evaluation and 0 after 1 month of follow-up (P < 0.01). The mean Visual Analogue Scale and McGill Pain Index scores were 8.1 and 34, respectively, at the first evaluation, and 1.5 and 16.6 at follow-up (P < 0.01). CONCLUSION: Thiele massage appears to be very helpful for women with CPP caused by tenderness of the levator ani muscle. However, these results are preliminary and a larger number of women are necessary to obtain more conclusive results.

Apoptosis induced by neoadjuvant chemotherapy in breast cancer.

AIM: To evaluate the relationship between apoptosis induced by chemotherapy and clinical response in breast cancer. METHODS: Apoptosis index (AI), mutant p53 and Bcl-2 protein expression were evaluated in 44 breast tumour samples from patients submitted to neoadjuvant chemotherapy. Objective response (OR) to primary chemotherapy was observed in 37 patients (84%) and no response (NR) in seven. AI was measured by the rate of apoptotic cells identified using morphological criteria. p53 and Bcl-2 protein expression were evaluated using an immunoperoxidase staining technique. RESULTS: The median AI change observed between pre-chemotherapy AI and post-chemotherapy AI was 0.84 in the OR group and 0.01 in the NR group, (rho = 0.4; p = 0.006). There was no change in Bcl-2 protein expression following chemotherapy. In the OR group, p53 protein expression was positive in 41.6% of patients before and in 22.2% after chemotherapy (difference = 16.6%; p = 0.03). No change was detected in the NR group. CONCLUSION: A positive correlation was found between the increase in AI and clinical response to neoadjuvant chemotherapy in locally advanced breast cancer.
