Background: Chronic pelvic, perineal and gluteal neuralgia is often experienced in a similar way to neuropathic pain, in the territories of four nerves: ilio-inguinal, pudendal, inferior cluneal and posterior gluteal nerves. These pains are often refractory to medical treatment based on the use of systemic molecules with disabling adverse effects and surgical procedure may be necessary. Objective: The objective of this study was to evaluate the efficacy and safety of treatment with a high-concentration capsaicin patch in these indications. Study Design: This study was prospective, nonrandomized, and observational. Setting: Federative Center of Pelvi-Perineology in the University Hospital of Nantes, France. Methods: Sixty patients with pelvic neuralgia were treated with high-concentration capsaicin patch. The primary endpoint was Patient Global Impression of Change (PGIC) and secondary endpoints included pain intensity on a Numerical Rating Scale (NRS), maximum sitting duration at the end of the day, Medication Consumption Score (MQS), and patient global improvement (from -100% to + 100%). Results: Twenty four percent of the 60 patients included in the study declared that they felt “very much improved” or “much improved” (PGIC = 1 or 2) and these patients reported an average 58% improvement and a 3.4-point reduction on the NRS. Among the “good responder” patients, patients with coccygodynia appear to obtain the best results, as 37% of these patients declared that they were much improved with an average 63% improvement No serious adverse effects were observed and treatment was well tolerated. Limitation: This study is limited by its relatively small sample size and non-randomized study. Conclusion: These results suggest the value of high-concentration capsaicin 8% patch in the treatment strategy for patients with chronic pelvic, perineal and gluteal neuralgia. This treatment would be particularly indicated in the management of coccygodynia.

Yoon H-K, Kim Y-K, Han C, Ko Y-H, Lee H-J, Kwon D-Y, Kim L. Paliperidone in the treatment of delirium: results of a prospective open-label pilot trial.Objective: Delirium is a life-threatening neuropsychiatric syndrome characterised by disturbances in consciousness, attention, cognition and perception. Antipsychotics are considered the drugs of choice in managing the symptoms of delirium. Paliperidone is a benzisoxazole derivative and the principal active metabolite of risperidone. In this study, we aimed to evaluate the efficacy of paliperidone for the treatment of delirium.Methods: A prospective open-label study of paliperidone for delirium treatment was performed with 6-day follow-up. Fifteen patients who met Diagnostic and Statistical Manual of Mental disorders, Fourth Edition criteria for delirium and had a score of 13 on the Delirium Rating Scale were recruited. The starting dose was 3 mg once a day and the dose was adjusted depending on the status of delirium. Daily assessments of the severity of delirium were evaluated using Memorial Delirium Assessment Scale (MDAS).Results: The mean daily maintenance dose of paliperidone was 3.75 ± 1.06. The MDAS scores before and after treatment (day 7) were 23.60 ± 6.31 and 11.33 ± 5.45 (t = 6.78, p < 0.001), respectively. The intensity of delirium showed a statistically significant reduction in MDAS scores from the first day of treatment. No serious adverse effects were observed, and none of the patients discontinued paliperidone because of adverse effects.Conclusions: This study shows that low-dose paliperidone is effective in reducing behavioural disturbances and symptoms in delirium and is well tolerated in delirious patients. This trial is an open-label study with a small sample size, and further controlled studies will be necessary.

Background: The recent interest in targeting the dorsal root ganglion (DRG) has led to the development of new techniques of electrode placement. In this article, we describe a new “Transgrade” approach to the DRG, accessing the contralateral interlaminar space and steering the lead out the opposite foramen. Objectives: The purpose of this study was to evaluate the Transgrade technique to the DRG in the management of focal neuropathic pain, predominately complex regional pain syndrome in terms of efficacy and safety. Study Design: A retrospective, observational review of all patients selected for DRG stimulation using the Transgrade technique to the DRG. Setting: Pain Management and Neuromodulation Centre, Guys and St. Thomas NHS Foundation Trust, London, United Kingdom. Methods: Data were taken from a hospital password-protected database. All patients were contacted by telephone for Numeric Rating Scale (NRS-11) score, Patient Global Impression of Change (PGIC) score, and complications. A patient responder was defined as having a PGIC score of 6 or 7, and a 2-point reduction from baseline NRS-11. Results: A total of 39 patients (46% women) with a mean age of 46 years (± 2) underwent a trial of DRG stimulation that resulted in an implantation rate of 82% (32 of 39). The responder rates, according to NRS-11 and PGIC results, were 87% (28 of 32) at 6 weeks and 66% (21 of 32) at a mean of 18 months (± 1.8) follow-up. Pocket pain was the most common complication, occurring in 7 of 32 (22%) patients, and the lead migration rate was 3 out of 57 leads placed (5.2%). A burst protocol was the favored method of stimulation in the majority of patients, 25 of 32 (78%). Limitations: Retrospective nature of design, small sample size. Conclusions: The Transgrade technique of placing DRG leads offers an alternative method that is safe and effective. New methods of stimulation to the DRG offer more choice and potentially better efficacy for patients with chronic neuropathic pain.

Abstract BACKGROUND Secondary to the complex care, involved specialty providers, and various etiologies, chronic pelvic pain patients do not receive holistic care. OBJECTIVE To compare our general and neuromodulation cohorts based on referrals, diagnosis, and therapy and describe our neuromodulation patients. METHODS A multidisciplinary team was established at our center. The intake coordinator assessed demographics and facilitated care of enrolled patients. Outcomes were compared using minimal clinical important difference of current Numerical Rating Scale (NRS) between patients with neuropathic pain who received neuromodulation and those who did not. The neuromodulation cohort completed outcome metrics at baseline and recent follow-up, including NRS score (best, worst, and current), Oswestry Disability Index (ODI), Beck Depression Inventory, and Pain Catastrophizing Scale. RESULTS Over 7 yr, 233 patients were referred to our consortium and 153 were enrolled. A total of 55 patients had neuropathic pain and 44 of those were managed medically. Eleven underwent neuromodulation. A total of 45.5% patients of the neuromodulation cohort were classified as responders by minimal clinically important difference compared to 26.6% responders in the control cohort at most recent follow-up (median 25 and 33 mo, respectively). Outcome measures revealed improvement in NRS at worst (P = .007) and best (P = .025), ODI (P = .014), and Pain Catastrophizing Scale Rumination (P = .043). CONCLUSION Eleven percent of patients were offered neuromodulation. There were more responders in the neuromodulation cohort than the conservatively managed neuropathic pain cohort. Neuromodulation patients showed significant improvement at 29 mo in NRS best and worst pain, disability, and rumination. We share our algorithm for patient management.

AbstractScrambler therapy is a noninvasive electroanalgesia technique designed to remodulate the pain system. Despite growing evidence of its efficacy in patients with neuropathic pain, little is known about the clinical factors associated with treatment outcome. We conducted a prospective, open-label, single-arm trial to assess the efficacy and safety of scrambler therapy in patients with chronic neuropathic pain of various etiologies. A post-hoc analysis was performed to investigate whether cluster analysis of the Neuropathic Pain Symptom Inventory (NPSI) profiles could identify a subgroup of patients regarding neuropathic pain phenotype and treatment outcome. Scrambler therapy resulted in a significant decrease in the pain numerical rating scale (NRS) score over 2 weeks of treatment (least squares mean of percentage change from baseline, − 15%; 95% CI − 28% to − 2.4%; p < 0.001). The mean score of Brief Pain Inventory (BPI) interference subdimension was also significantly improved (p = 0.022), while the BPI pain composite score was not. Hierarchical clustering based on the NPSI profiles partitioned the patients into 3 clusters with distinct neuropathic pain phenotypes. Linear mixed-effects model analyses revealed differential response to scrambler therapy across clusters (p = 0.003, pain NRS; p = 0.072, BPI interference subdimension). Treatment response to scrambler therapy appears different depending on the neuropathic pain phenotypes, with more favorable outcomes in patients with preferentially paroxysmal pain rather than persistent pain. Further studies are warranted to confirm that capturing neuropathic pain phenotypes can optimize the use of scrambler therapy.

Background : Case reports have suggested possible effects of lipophilic statins on sleep in some subjects. Most randomized studies evaluating the effect of statins on sleep have had small sample size and short duration (≤ 6 weeks). Whether statins affect sleep on average, favorably or adversely, has been unclear. Goal : To assess the effects of lipophilic and hydrophilic statins on sleep. Subjects : 1016 adult men and women without diabetes or heart disease, with LDL-cholesterol 115–190mg/dL. Design : Randomized double blind placebo-controlled trial of simvastatin 20mg, pravastatin 40mg or placebo for 6 months. Sleep was a prespecified secondary outcome. It was assessed by both an adaptation of the Leeds sleep scale (a visual analog scale of sleep quality); and a rating scale of sleep problems. Both items were measured at baseline and on-treatment. Analysis : Baseline comparability of randomization groups including sleep measures was affirmed. T-test of mean on-treatment sleep scores across randomization groups was performed. This complemented regression analyses, adjusted for baseline values of the respective sleep assessment. Results : Groups were comparable at baseline on variables including both sleep measures. Simvastatin use was associated with significantly worse sleep quality, and significantly greater reported sleep problems than either pravastatin or placebo, by t-test and regression analyses. Pravastatin did not differ significantly from placebo on any sleep outcome. Conclusion : Findings were compatible with the hypothesis that statins may impair sleep in some subjects, and that this impairment may arise selectively with lipophilic statins. Table 1.

This study was undertaken to investigate the effects of acupuncture in low back and pelvic pain during pregnancy under real life conditions, as compared with patients undergoing conventional treatment alone. A total of 61 conventionally treated pregnant women were allocated randomly into two groups to be treated or not by acupuncture. Twenty-seven patients formed the study group and 34 the control group. They reported the severity of pain using a Numerical Rating Scale from 0 to 10, and their capacity to perform general activities, to work, and to walk. We also assessed the use of analgesic drugs. Women were followed up for eight weeks and interviewed five times, at two-week intervals. All women completed the study. In the study group the average pain during the study period showed a larger reduction (4.8 points) than the control group (−0.3 points) (P<0.0001). Average pain scores decreased by at least 50% over time in 21 (78%) patients in the acupuncture group and in five (15%) patients in the control group (P<0.0001). Maximum pain and pain at the moment of interview were also less in the acupuncture group compared with the control group. The capacity to perform general activities, to work and to walk was improved significantly more in the study group than in the control group (P<0.05). The use of paracetamol was lower in the acupuncture group (P<0.01). These results indicate that acupuncture seems to alleviate low back and pelvic pain during pregnancy, as well as to increase the capacity for some physical activities and to diminish the need for drugs, which is a great advantage during this period.

Abstract Introduction:Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are rare, life-threatening conditions caused mainly by drugs. Their management relies on the withdrawal of the culprit medication and supportive measures. Different pharmacotherapies have varied effects. However, data related to TEN and SJS in Saudi is limited. This study aimed to identify the causative agents, associated factors, and outcomes of TEN/SJS cases admitted to a teaching hospital (King Abdulaziz University) in Jeddah during the last 10 years.Methods: We retrospectively analyzed the data of TEN/SJS patients admitted to the hospital over the last 10 years.Results: We identified 12 patients with TEN/SJS. Of these, nine survived the condition and were discharged. The culprit medication was identified in eight of them, including antibiotics in six cases and Tegretol and allopurinol in one case each. Most of the patients received systemic steroids and intravenous immunoglobulins.Conclusion: TEN/SJS is mainly caused by medications of which antibiotics are the most implicated. Consistent with other studies, the mortality rate associated with TEN/SJS in Saudi is 25%. Limitations: restricted to a single center and small sample size.

Background: Topical capsaicin therapy may be of benefit in providing pain relief in patients with peripheral neuropathy. Objectives: To investigate the efficacy and safety of 0.625% (50 µg/cm2 ) and 1.25% (100 µg/cm2 ) capsaicin patches (CPs) compared to conventional 0.075% capsaicin cream or placebo patches in patients suffering from peripheral neuropathy. Study Design: Early Phase II, multi-center, randomized, semi-double-blind, and placebocontrolled clinical trial. Setting: Two medical college teaching hospitals. Methods: Sixty patients were randomized to the 0.625% CP, 1.25% CP, placebo-controlled patch, or 0.075% capsaicin cream. The primary efficacy endpoint was the mean difference in the change of daily numerical rating scale (NRS) pain score. Secondary endpoints included values for the Daily Sleep Interference Scale, the percentage of patients achieving a ≥ 30% or ≥ 50% reduction in pain, and data for Global Impression Change (GIC) and EQ-5D. Results: Patients treated with the 0.625% CP and 0.075% capsaicin cream showed statistically significant improvements in pain after 6-weeks of test drug application. Daily sleep disorder scores were improved only for those patients applying the 0.075% capsaicin cream. For patient-derived GIC scores, the majority (11 of 12) of patients in the 0.625% CP group reported that their pain was improved. For the safety evaluation, 2 severe adverse events were reported for the 0.075% capsaicin cream group only. Repetitive patch application was related to minor skin problems such as a burning sensation, erythema, pruritus, and vesicles in 28 patients (46.67%). Limitations: The small sample size and relatively high dropout rates. Conclusion: Our data indicate that the 0.625% CP may prove to be an effective and safe alternative with which to treat patients with peripheral neuropathy and could replace the high concentration (8%) CP. Further studies are now needed to definitively establish efficacy. Key words: Capsaicin, patch, CP, topical capsaicin, neuropathic pain, peripheral neuropathic pain, PNP, high concentration CP

Scrambler Therapy

Background: Chemotherapy-induced peripheral neuropathy (CIPN) affects 30% to 40% of patients with cancer with long-lasting disability. Scrambler therapy (ST) appeared to benefit patients in uncontrolled trials, so we performed a randomized sham-controlled Phase II trial of ST. Methods: The primary end point was “average pain” after 28 days on the Numeric Rating Scale. Each received ten 30-minute sessions of ST on the dermatomes above the painful areas, or sham treatment on the back, typically at L3-5 where the nerve roots would enter the spinal cord. Outcomes included the Brief Pain Inventory (BPI)-CIPN and the EORTC CIPN-20 scale. Patients were evaluated before treatment (day 0), day 10, and days 28, 60, and 90. Results: Data regarding pain as a primary outcome were collected for 33 of the 35 patients. There were no significant differences between the sham and the “real” ST group at day 10, 28, 60, or 90, for average pain, the BPI, or EORTC CIPN-20. Individual responses were noted during the ST treatment on the real arm, but most dissipated by day 30. There was improvement in the sensory subscale of the CIPN-20 at 2 months in the “real” group ( P = .14). All “real” patients wanted to continue treatment if available. Discussion: We observed no difference between sham and real ST CIPN treatment. Potential reasons include at least the following: ST does not work; the sham treatment had some effect; small sample size with heterogeneous patients; misplaced electrodes on an area of nonpainful but damaged nerves; or a combination of these factors.
