MATERIALS AND METHODS: Eighty patients for laparoscopic surgery with at least one of the determined risks (nonsmoker, female, previous PONV/motion sickness, or postoperative opioid use) were randomized into either an active or sham group. At the end of surgery, Reletex electrical acustimulation was placed at the P6 acupoint. The active group had grade 3 strength and the sham group had inactivated electrodes covered by silicone. It was worn for 24 h following surgery. PONV scores were recorded.
RESULTS: The active group had significantly shorter durations of surgery and lower PONV incidence over 24 h (35.1% versus 64.9%, P = 0.024) and this was attributed to the lower incidence of nausea (31.4% versus 68.6%, P = 0.006). The overall incidence of vomiting was not significantly different between the groups, but it was higher in the sham group of patients with PONV risk score 3 (23.9%, P = 0.049).
CONCLUSION: In patients at high risk for PONV, P6 acupoint electrical stimulation lowers the PONV incidence by reducing the nausea component. However, this reduction in nausea is not related to increasing PONV risk scores.
MATERIALS AND METHODS: Atrial arrhythmogenesis was investigated in Langendorff-perfused young (3-4 month) and aged (>12 month), wild type (WT) and peroxisome proliferator activated receptor-γ coactivator-1β deficient (Pgc-1β-/-) murine hearts modeling age-dependent chronic mitochondrial dysfunction during regular pacing and programmed electrical stimulation (PES).
RESULTS AND DISCUSSION: The Pgc-1β-/- genotype was associated with a pro-arrhythmic phenotype progressing with age. Young and aged Pgc-1β-/- hearts showed compromised maximum action potential (AP) depolarization rates, (dV/dt)max, prolonged AP latencies reflecting slowed action potential (AP) conduction, similar effective refractory periods and baseline action potential durations (APD90) but shortened APD90 in APs in response to extrasystolic stimuli at short stimulation intervals. Electrical properties of APs triggering arrhythmia were similar in WT and Pgc-1β-/- hearts. Pgc-1β-/- hearts showed accelerated age-dependent fibrotic change relative to WT, with young Pgc-1β-/- hearts displaying similar fibrotic change as aged WT, and aged Pgc-1β-/- hearts the greatest fibrotic change. Mitochondrial deficits thus result in an arrhythmic substrate, through slowed AP conduction and altered repolarisation characteristics, arising from alterations in electrophysiological properties and accelerated structural change.
METHOD: Eligible patients with chronic wounds were enrolled between March and June 2016, from the Wound Care Unit, Hospital Kuala Lumpur in this consecutive case series. Standard wound care was performed with microcurrent as an adjunct therapy. Each patient was treated with an anti-inflammatory frequency, followed by a vasodilation frequency, while having their wounds cleansed during each dressing change. Patients were loaned a home-microcurrent device to treat themselves three times daily using a tissue repair frequency for four weeks.
RESULTS: A total of 100 patients with chronic wounds, such as diabetic foot ulcers, venous leg ulcers, and pressure ulcers, were recruited. During the four-week treatment period, all patients had a reduction in wound size, with 16 having complete wound closure. All 89 of the 100 patients who complained of pain, associated with their wound, experienced reduced pain scores, with 11 being pain-free at the end of the four-week period. There was significant reduction (p<0.001) in both mean pain score and mean wound area during the treatment period, as well as improvements in other parameters, such as reduction in inflammatory symptoms (leg swelling, foot stiffness), increased vasodilation (skin discolouration, leg heaviness, early morning erection, sensation), improvement in sleep quality, gait, and frequency of bowel movement. No adverse events were reported.
CONCLUSION: The results of this study show there was significant reduction in wound area and pain score during the treatment period. The ease of use of microcurrent devices would advocate its use in accelerating wound healing.
Patients and methods: This single-blind, prospective, randomized-controlled study included a total of 20 patients (8 males, 12 females; mean age: 53.5±13.8; range, 31 to 82 years) with chronic neuropathic pain between January 2014 and June 2014. The patients were randomized to BEST (n=10) or placebo (n=10) group. Pain was measured using the Visual Analog Scale, and serum cortisol levels were measured before and after treatment.
Results: There was no significant difference in the baseline demographics, diagnosis, and treatment modalities between the groups. Approximately 50% patients in the treatment group reported that the treatment was effective, compared to 30% in the placebo group. Pain score reduction after treatment in the BEST group was significant (p<0.05), while it was not significant in the placebo group (p=0.4). Cortisol levels significantly reduced only in the BEST group after treatment (p=0.013).
Conclusion: The BEST yields reduction in pain severity and cortisol levels. Based on these results, it seems to be effective in the treatment of chronic neuropathic pain after a single treatment and may be more effective for long-term management.
