A Case Report: An Acute Spinal Epidural Hematoma after Acupuncture Mimicking Stroke.

BACKGROUND: Spinal epidural hematoma (SEH) after acupuncture is rare and may present with acute or subacute onset and varied symptoms, making it difficult to diagnose. This condition can mimic acute stroke, so it is vital to establish a clear diagnosis before considering thrombolytic therapy, which could be disastrous if applied inappropriately. CASE REPORT: We describe a 52-year-old man who presented to our emergency department (ED) with acute onset of unilateral weakness of the limbs for 3.5 h immediately after receiving acupuncture at the bilateral neck and back. The acute stroke team was activated. In the ED, computer tomography angiography from the aortic arch to the head revealed spinal epidural hematoma. The patient was admitted to the ward for conservative treatment and was discharged with subtle residual symptoms of arm soreness 5 days later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Acute spinal epidural hematoma rarely presents with unilateral weakness of the limbs, mimicking a stroke. Because inappropriate thrombolysis can lead to devastating symptoms, spinal epidural hematoma should be excluded when evaluating an acute stroke patient with a history of acupuncture who is a possible candidate for thrombolytic therapy.

Laser Acupuncture for Carpal Tunnel Syndrome: A Single-Blinded Controlled Study.

Objectives: This study aimed to compare the efficacy of laser acupuncture (LA) treatment with that of placebo LA treatment in patients with idiopathic, mild-to-moderate carpal tunnel syndrome (CTS), as measured by subjective symptom assessments and objective changes in nerve conduction studies (NCSs). Design: A randomized, single-blinded, controlled study. Settings: A Teaching Hospital in the Taichung, Taiwan between March 2013 and November 2013. Subjects: 84 consecutive treatment-naive patients with CTS. Interventions: Participants were randomly divided into two treatment arms: (1) LA, administered at traditional Chinese acu-points on the affected side, once a day, 5 times a week, for 4 weeks (N = 43); and (2) placebo LA, administered using the same device and protocol, with the LA device switched off (N = 41). Outcome measures: Patients completed the Global symptom score (GSS) at baseline and two and four weeks later. The primary outcome was changes in GSS. NCSs were performed at baseline and repeated at the end of the study as a secondary outcome. Results: There was a significantly greater reduction in GSS in the LA group than in the placebo group at week 2 (-9.30 ± 4.94 vs. -2.29 ± 4.27, respectively, P < 0.01) and at week 4 (-10.67 ± 5.98 vs. -2.90 ± 5.61, respectively, P < 0.01). However, NCSs did not show significant difference between the two groups. Conclusions: LA may be more effective than placebo LA in the treatment of mild-to-moderate idiopathic CTS in terms of subjective measurement. For patients who fear needle-based treatment, such as acupuncture or local injections, or those who do not opt for early surgical decompression, LA treatment can be considered as an effective and alternative form of acu-points stimulation therapy.

Prognosis of cerebral lipiodol embolism caused by transarterial chemoembolization.

OBJECTIVES: Transarterial chemoembolization (TACE) plays an essential role in the management of unresectable hepatocellular cell carcinoma and other hepatic neoplasms. Cerebral lipiodol embolism (CLE) is a rare complication of TACE and its prognostic factors have not been well studied. The aim of this paper was to elucidate the prognostic factors of CLE based on clinical data obtained from our patients and cases published since 2004. METHODS: We present two patients with CLE, analyze the clinical data, and review all CLE cases published since 2004. A poor outcome was defined as stupor, coma, quadriplegia, or death within 45 days. Patients who had other neurological conditions within 45 days were considered as having a good outcome. RESULTS: The rate of poor outcome was 25.7% (9/35). Compared with the patients with good outcome, those with poor outcome were older (mean age 68.3 ± 7.3 vs. 58.3 ± 10.6 years, p = 0.03), more often female (76.9% vs. male 33.3%, p = 0.02), and more likely chemoembolized via both the right hepatic and right inferior phrenic arteries (44.4 vs. 8.7%, p = 0.02). DISCUSSION: The prognosis of CLE was related to age, gender, and the arteries selected for injection.

Chinese Medicinal Formula (MHGWT) for Relieving Diabetic Neuropathic Pain: A Randomized, Double-Blind, Placebo-Controlled Trial.

Objective. To investigate the effects of modified Hungqi Guizhi Wuwu Tang (MHGWT), a formula that comprises Chinese medicinal herbs, in relieving neuropathic pain in diabetics. Method. Between March 2008 and April 2009, 112 participants were randomly assigned to either the MHGWT group, whose members received MHGWT (n = 56), or the control group, whose members received a placebo (n = 56). Diabetic neuropathic pain (DNP) was rated using the 15-item Short-Form Brief Pain Inventory (SF-BPI), the 17-item Short-Form McGill Pain Questionnaire (SF-MPQ), the 13-item Modified Michigan Neuropathy Screening Instrument (MMNSI), and the 36-item "SF-36." Nerve conduction studies (NCSs) were performed before and after treatment. Results. After 12 weeks of treatment, the SF-MPQ and SF-BPI scores of the MHGWT group were significantly (P < 0.05) reduced and a significant difference between the groups was observed (P < 0.05). The levels of NCS in the MHGWT group were nonsignificantly (P > 0.05) reduced, and no significant difference in NCS level was observed between the groups (P > 0.05). Conclusions. MHGWT shows promise in relieving DNP and deserves further investigation.

Predicting prognostic factors in a randomized controlled trial of acupuncture versus topiramate treatment in patients with chronic migraine.

BACKGROUND: This study aimed to identify predictive factors of outcome in patients with chronic migraine (CM) treated with acupuncture or topiramate in a randomized controlled trial. METHODS: Sixty-six consecutive CM patients were treated with either acupuncture (n=33) or topiramate (n=33) in a 12-week period. Data on potential predictive factors were collected at baseline, and secondary data analysis was performed to identify factors associated with treatment response. Treatment prognosis was defined as the change in mean number of moderate/severe headache days per 4 weeks from the 4-week baseline periods. RESULTS: The median change in mean number of moderate/severe headache days per 4 weeks for patients with higher baseline headache days (>20 d) was significantly greater than that for lower baseline headache days (≤ 20 d) (median ± interquartile range: -12 ± 2 vs. -10 ± 1 d, P=0.01) in acupuncture group. There was a greater change in mean number of moderate/severe headache days per 4 weeks for high moderate/severe headache days (>20 d) than in low days (≤ 20 d) (-12 ± 1 vs. -10 ± 2 d, P=0.015) in acupuncture group. patients with throbbing symptoms had better prognosis with acupuncture than those without throbbing (-12 ± 2 vs. -9.5 ± 2.5 d, P=0.004). Higher score (>5 points) in the general expectations for improvement predicted better response in both treatment groups (>5 vs. ≤ 5 points: -12 ± 2 vs. -9 ± 2 d for acupuncture group; -10 ± 3 vs. -7 ± 4 d for topiramate group; P<0.001). CONCLUSIONS: Some variables can predict outcome in acupuncture or topiramate treatment of CM patients. Identifying predictors of prognosis of both treatments for CM may help improve outcomes in future work.

A randomized clinical trial of acupuncture versus oral steroids for carpal tunnel syndrome: a long-term follow-up.

UNLABELLED: We prospectively followed up patients with carpal tunnel syndrome (CTS) in our previous study for 1 year. A total of 77 consecutive patients with electrophysiologically confirmed mild-to-moderate idiopathic CTS were randomized and assigned into 2 treatment arms: 1) 2 weeks of prednisolone 20 mg daily followed by 2 weeks of prednisolone 10 mg daily (n = 39); and 2) acupuncture administered in 8 sessions over 4 weeks (n = 38). In the current study, the patients were further followed up at 7 and 13 months using Global symptom score (GSS) assessments and nerve conduction studies repeated again at 13 months. When comparing with baseline levels, the percentages of patients with treatment failure, moderate improvement, and good improvement were significantly different between the 2 groups at month 7 [10.5, 2.6, and 86.8% for the acupuncture group and 33.3, 7.7, and 59% for the steroid group, respectively (P = .014)] and month 13 [15.8, 2.6, and 81.6% versus 51.3, 0, and 48.7%, respectively (P = .002)]. The acupuncture group had a significantly better improvement in GSS, distal motor latencies and distal sensory latencies when compared to the steroid group throughout the 1-year follow-up period (P < .01). Furthermore, significant correlation was observed between changes of GSS (month 13-baseline) and all parameters of the electrophysiological assessments except for compound muscle action potential amplitude. PERSPECTIVE: This article demonstrates that short-term acupuncture treatment may result in long-term improvement in mild-to-moderate idiopathic CTS. Acupuncture treatment can be considered as an alternative therapy to other conservative treatments for those who do not opt for early surgical decompression.

Escalated regeneration in sciatic nerve crush injury by the combined therapy of human amniotic fluid mesenchymal stem cells and fermented soybean extracts, Natto.

Attenuation of inflammatory cell deposits and associated cytokines prevented the apoptosis of transplanted stem cells in a sciatic nerve crush injury model. Suppression of inflammatory cytokines by fermented soybean extracts (Natto) was also beneficial to nerve regeneration. In this study, the effect of Natto on transplanted human amniotic fluid mesenchymal stem cells (AFS) was evaluated. Peripheral nerve injury was induced in SD rats by crushing a sciatic nerve using a vessel clamp. Animals were categorized into four groups: Group I: no treatment; Group II: fed with Natto (16 mg/day for 7 consecutive days); Group III: AFS embedded in fibrin glue; Group IV: Combination of group II and III therapy. Transplanted AFS and Schwann cell apoptosis, inflammatory cell deposits and associated cytokines, motor function, and nerve regeneration were evaluated 7 or 28 days after injury. The deterioration of neurological function was attenuated by AFS, Natto, or the combined therapy. The combined therapy caused the most significantly beneficial effects. Administration of Natto suppressed the inflammatory responses and correlated with decreased AFS and Schwann cell apoptosis. The decreased AFS apoptosis was in line with neurological improvement such as expression of early regeneration marker of neurofilament and late markers of S-100 and decreased vacuole formation. Administration of either AFS, or Natto, or combined therapy augmented the nerve regeneration. In conclusion, administration of Natto may rescue the AFS and Schwann cells from apoptosis by suppressing the macrophage deposits, associated inflammatory cytokines, and fibrin deposits.

Acupuncture in patients with carpal tunnel syndrome: A randomized controlled trial.

OBJECTIVES: To investigate the efficacy of acupuncture compared with steroid treatment in patients with mild-to-moderate carpal tunnel syndrome (CTS) as measured by objective changes in nerve conduction studies (NCS) and subjective symptoms assessment in a randomized, controlled study. METHODS: A total of 77 consecutive and prospective CTS patients confirmed by NCS were enrolled in the study. Those who had fixed sensory complaint over the median nerve and thenar muscle atrophy were excluded. The CTS patients were randomly divided into 2 treatment arms: (1) 2 weeks of prednisolone 20 mg daily followed by 2 weeks of prednisolone 10 mg daily (n = 39), and (2) acupuncture administered in 8 sessions over 4 weeks (n = 38). A validated standard questionnaire as a subjective measurement was used to rate the 5 major symptoms (pain, numbness, paresthesia, weakness/clumsiness, and nocturnal awakening) on a scale from 0 (no symptoms) to 10 (very severe). The total score in each of the 5 categories was termed the global symptom score (GSS). Patients completed standard questionnaires at baseline and 2 and 4 weeks later. The changes in GSS were analyzed to evaluate the statistical significance. NCS were performed at baseline and repeated at the end of the study to assess improvement. All main analyses used intent-to-treat. RESULTS: A total of 77 patients who fulfilled the criteria for mild-to-moderate CTS were recruited in the study. There were 38 in the acupuncture group and 39 in the steroid group. The evaluation of GSS showed that there was a high percentage of improvement in both groups at weeks 2 and 4 (P < 0.01), though statistical significance was not demonstrated between the 2 groups (P = 0.15). Of the 5 main symptoms scores (pain, numbness, paresthesia, weakness/clumsiness, nocturnal awakening), only 1, nocturnal awakening, showed a significant decrease in acupuncture compared with the steroid group at week 4 (P = 0.03). Patients with acupuncture treatment had a significant decrease in distal motor latency compared with the steroid group at week 4 (P = 0.012). Acupuncture was well tolerated with minimal adverse effects. CONCLUSIONS: Short-term acupuncture treatment is as effective as short-term low-dose prednisolone for mild-to-moderate CTS. For those who do have an intolerance or contraindication for oral steroid or for those who do not opt for early surgery, acupuncture treatment provides an alternative choice.

Dietary supplement with fermented soybeans, natto, improved the neurobehavioral deficits after sciatic nerve injury in rats.

Clearance of fibrin and associated inflammatory cytokines by tissue-type plasminogen activator (t-PA) is related to improved regeneration in neurological disorder. The biological activity of fermented soybean (natto) is very similar to that of t-PA. We investigated the effect of the dietary supplement of natto on peripheral nerve regeneration. The peripheral nerve injury was produced by crushing the left sciatic nerve with a vessel clamp in Sprague-Dawley rats. The injured animals were fed orally either with saline or natto (16 mg/day) for seven consecutive days after injury. Increased functional outcome such as sciatic nerve functional index, angle of ankle, compound muscle action potential and conduction latency were observed in natto-treated group. Histological examination demonstrated that natto treatment improved injury-induced vacuole formation, S-100 and vessel immunoreactivities and axon loss. Oral intake of natto prolonged prothrombin time and reduced fibrinogen but did not change activated partial thromboplastin time and bleeding time. Furthermore, natto decreased injury-induced fibrin deposition, indicating a tolerant fibrinolytic activity. The treatment of natto significantly improved injury-induced disruption of blood-nerve barrier and loss of matrix component such as laminin and fibronectin. Sciatic nerve crush injury induced elevation of tumor necrosis factor alpha (TNF-alpha) production and caused apoptosis. The increased production of TNF-alpha and apoptosis were attenuated by natto treatment. These findings indicate that oral intake of natto has the potential to augment regeneration in peripheral nerve injury, possibly mediated by the clearance of fibrin and decreased production of TNF-alpha.

Human amniotic fluid mesenchymal stem cells in combination with hyperbaric oxygen augment peripheral nerve regeneration.

PURPOSE: Attenuation of pro-inflammatory cytokines and associated inflammatory cell deposits rescues human amniotic fluid mesenchymal stem cells (AFS) from apoptosis. Hyperbaric oxygen (HBO) suppressed stimulus-induced pro-inflammatory cytokine production in blood-derived monocyte-macrophages. Herein, we evaluate the beneficial effect of hyperbaric oxygen on transplanted AFS in a sciatic nerve injury model. METHODS: Peripheral nerve injury was produced in Sprague-Dawley rats by crushing the left sciatic nerve using a vessel clamp. The AFS were embedded in fibrin glue and delivered to the injured site. Hyperbaric oxygen (100% oxygen, 2 ATA, 60 min/day) was administered 12 h after operation for seven consecutive days. Transplanted cell apoptosis, oxidative stress, inflammatory cell deposits and associated chemokines, pro-inflammatory cytokines, motor function, and nerve regeneration were evaluated 7 and 28 days after injury. RESULTS: Crush injury induced an inflammatory response, disrupted nerve integrity, and impaired nerve function in the sciatic nerve. However, crush injury-provoked inflammatory cytokines, deposits of inflammatory cytokines, and associated macrophage migration chemokines were attenuated in groups receiving hyperbaric oxygen but not in the AFS-only group. No significant increase in oxidative stress was observed after administration of HBO. In transplanted AFS, marked apoptosis was detected and this event was reduced by HBO treatment. Increased nerve myelination and improved motor function were observed in AFS-transplant, HBO-administrated, and AFS/HBO-combined treatment groups. Significantly, the AFS/HBO combined treatment showed the most beneficial effect. CONCLUSION: AFS in combination with HBO augment peripheral nerve regeneration, which may involve the suppression of apoptotic death in implanted AFS and the attenuation of an inflammatory response detrimental to peripheral nerve regeneration.
