The burden of headache and a health-care needs assessment in the adult population of Mali: a cross-sectional population-based study.

BACKGROUND: Our recent studies have shown headache disorders to be very common in the central and western sub-Saharan countries of Benin and Cameroon. Here we report headache in nearby Mali, a strife-torn country that differs topographically, culturally, politically and economically. The purposes were to estimate headache-attributed burden and need for headache care. METHODS: We used cluster-random sampling in seven of Mali's eleven regions to obtain a nationally representative sample. During unannounced household visits by trained interviewers, one randomly selected adult member (18-65 years) from each household was interviewed using the structured HARDSHIP questionnaire, with enquiries into headache in the last year and, additionally, headache yesterday (HY). Headache on ≥ 15 days/month (H15+) was diagnosed as probable medication-overuse headache (pMOH) when associated with acute medication use on ≥ 15 days/month, and as "other H15+" when not. Episodic headache (on < 15 days/month) was recorded as such and not further diagnosed. Burden was assessed as impaired participation (days lost from paid and household work, and from leisure activity). Need for headache care was defined by criteria for expectation of benefit. RESULTS: Data collection coincided with the SARS-CoV-2 pandemic. The participating proportion was nonetheless extremely high (99.4%). The observed 1-year prevalence of any headache was 90.9%. Age- and gender-adjusted estimates were 86.3% for episodic headache, 1.4% for pMOH and 3.1% for other H15+. HY was reported by 16.8% with a mean duration of 8.7 h. Overall mean headache frequency was 3.5 days/month. Participants with pMOH lost more days from paid (8.8 days/3 months) and household work (10.3 days/3 months) than those with other H15+ (3.1 and 2.8 days/3 months) or episodic headache (1.2 and 0.9 days/3 months). At population level, 3.6-5.8% of all time was spent with headache, which led to a 3.6% decrease in all activity (impaired participation). Almost a quarter (23.4%) of Mali's adult population need headache care. CONCLUSION: Headache is very common in Mali, as in its near neighbours, Benin and Cameroon, and associated with substantial losses of health and productivity. Need for headache care is high - a challenge for a low-income country - but lost productivity probably translates into lost gross domestic product.

Combination of anodal tDCS of the cerebellum with a goal-oriented motor training to treat cervical dystonia: a pilot case series.

Background: Transcranial Direct Current Stimulation (tDCS) of the cerebellum shows promise for the treatment of dystonia. Specific motor rehabilitation programs have also been developed in this context. However, the combination of these two approaches has not yet been evaluated to determine their therapeutic potential. Methods: We report a series of 5 patients with cervical dystonia (CD) poorly controlled by botulinum toxin injections. They were initially treated by a protocol of repeated daily sessions (for 3 or 5 days) of cerebellar anodal tDCS (cer-atDCS) applied alone. In a second time, additional protocols of cer-atDCS were performed in combination with a program of goal-oriented motor training exercises (Mot-Training), specifically developed for the treatment of CD. The clinical impact of the procedures was assessed on the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS). Results: Compared to baseline, the maximum percentage of TWSTRS total score improvement was 37% on average after cer-atDCS performed alone (p = 0.147, not significant) and 53% on average after cer-atDCS combined with Mot-Training (p = 0.014, significant). The TWSTRS pain and functional handicap subscores also improved after the combined protocol. A score of (+3) to (+5) was rated on the TWSTRS response scale after cer-atDCS performed alone or the combined protocol, corresponding to a moderate to striking improvement on dystonia and pain. This improvement lasted longer after the combined protocol than after cer-atDCS alone (3.4 vs. 1.4 months on average, p = 0.011). Conclusion: The combination of cer-atDCS with Mot-Training produced a greater and more prolonged improvement than the application of cer-atDCS alone. Such a combined therapeutic procedure is easy to perform and opens important perspectives in the long-term treatment of CD. These results remain to be confirmed by a randomized sham-controlled trial on a larger sample.

Effects of Combining Music Therapy, Light Therapy, and Chromotherapy in the Treatment of Chronic Pain Patients: A Pilot Study.

Background: It is currently considered that around 30% of chronic pain patients are totally refractory to medical treatment. Among patients who remain responsive to medical treatment, it is estimated that between 20% and 50% are likely to discontinue treatment due to severe side effects. Given these therapeutic difficulties, a significant number of patients turn to complementary therapies. Objective: The LineQuartz® is a medical device that combines 3 complementary therapies, namely, music therapy, light therapy, and chromotherapy. We propose to evaluate its effectiveness in chronic pain patients. Methods: Between October 2021 and October 2022, 44 patients aged between 23 and 85 years (mean: 55.4 years) were included in a prospective study. All patients had background pain intensity greater than 4/10 on the Numerical Pain Scale (NS). Treatment consisted of 4 half-hour sessions, divided into one session per week for 3 weeks (21 days). Patients were assessed by the Brief Pain Inventory (BPI) and the Hospital Anxiety and Depression scale (HAD) the day before starting treatment (Day 0) and the day after the end of treatment (Day 22). Results: Apart from the BPI item, "relationship with others," all items improved significantly (p < 0.050). Background pain intensity (NS) and frequency of painful attacks improved very significantly (p < 0.001). The HAD anxiety subscore was also significantly improved (p < 0.001). Discussion. This open pilot study supports the idea that LineQuartz® has a place among complementary therapies dedicated to the treatment of chronic pain. However, these results need to be confirmed by a controlled study.

Deep continuous sedation at the patient's request until death in a palliative care unit: retrospective study.

OBJECTIVES: Limited descriptive data are available on continuous and deep sedation maintained until death (CDSUD) at the patient's request in palliative care units. This study aimed to describe such practices in the context of refractory suffering or after a request to stop life-sustaining treatment, evaluating the duration and dosage of sedative treatments used. METHODS: This retrospective observational study included consecutively hospitalised patients in a palliative care unit from January 2020 to December 2021. Data on patient profiles, reasons for the sedation request, duration of sedation and doses of sedatives were collected. RESULTS: Among 42 patients who underwent CDSUD, 79% occurred due to refractory suffering. In cases of sedation following a request to stop life support, high-dose corticosteroid therapy was the most commonly involved life-sustaining treatment. Midazolam was always the first-line sedative treatment. Chlorpromazine was added in 79% of cases, and propofol in 40%, to achieve a deep level of sedation. The mean maximum doses of midazolam, chlorpromazine and propofol were 7.6 mg/hour (±1.9), 3.3 mg/hour (±0.9) and 1.7 mg/kg/hour, respectively. The average duration of sedation was 37 hours. CONCLUSIONS: This study provides new descriptive elements on CDSUD. Notably, it highlights the use of second-line sedative molecules, such as propofol.

Bicentre, randomized, parallel-arm, sham-controlled trial of transcranial direct-current stimulation (tDCS) in the treatment of palliative care patients with refractory cancer pain.

BACKGROUND: Pain is a common symptom in palliative care cancer patients and is often insufficiently relieved. In recent years, transcranial direct-current stimulation (tDCS) of the motor cortex has been shown to be effective to treat chronic pain, essentially neuropathic pain. We propose to test the efficacy of tDCS in patients experiencing cancer pain in the palliative care setting. METHOD/DESIGN: This article describes the protocol of a bicentre, randomized, parallel-arm, sham-controlled clinical trial evaluating tDCS in the treatment of palliative care patients with refractory cancer pain. Seventy patients between the ages of 18 and 80 years experiencing refractory pain with a pain score of 4/10 on a numerical rating scale (NRS) ranging from 0 to 10 will be enrolled in this trial. The main exclusion criteria are patients unable to fill in the various rating scales and life expectancy less than 3 weeks. Treatment consists of 5 consecutive tDCS sessions targeting the motor cortex (one daily session for 5 days) on the contralateral side to the pain. After randomization (1:1 ratio), 35 patients will receive active stimulation and 35 patients will receive sham stimulation. The primary endpoint is the NRS score and the primary objective is a significant improvement of this score between the baseline score recorded between D-3 and D-1 and the score recorded 4 days after stopping treatment (D8). The secondary objectives are to evaluate whether this improvement is maintained 16 days after stopping treatment (D21) and whether the following scores are improved on D14 and D21: Brief Pain Inventory, Edmonton Symptom Assessment System, Hospital Anxiety and Depression scale, State-Trait Anxiety Inventory and Medication Quantification Scale. DISCUSSION: Positive results of this trial would indicate that tDCS can improve pain and quality of life of cancer patients in the palliative care setting. Reduction of analgesic consumption and improvement of activities of daily living should allow many patients to return home with a decreased workload for caregivers.

A national media mass campaign improves beliefs and behaviours about low back pain in the general population and in general practitioners.

INTRODUCTION: Previous international mass-media campaigns for low back pain (LBP) have had conflicting impacts on the general population. The objective was to evaluate the impact of a national back pain campaign conducted between 2017 and 2019 on beliefs and behaviours of general practitioners and the general population in France. METHODS: Between 2017 and 2019, a mass-media campaign was used to disseminate positive messages about LBP using several media, along with a parallel campaign addressed to general practitioners. An email survey before the campaign and 6 and 18 months after the campaign started evaluated beliefs and behaviours among a representative sample of the 2 target populations (3500 people from the general population and 700 general practitioners before the campaign, and 2000 people and 300 general practitioners 6 and 18 months after). RESULTS: Overall, 56% of the general population respondents before the campaign and 74% and 75% at 6 and 18 months after adhered to the statement "One should maintain physical activity" when dealing with LBP. Conversely, the percentage adhering to the statement "The best treatment is resting" decreased significantly from 68% before the campaign to 45% at 6 and 18 months after. Physicians reported delivering more reassurance and giving more documentation to patients after the campaign. They prescribed less sick leave during the first consultation (65% before the campaign, 46% and 30% at 6 and 18 months after). CONCLUSION: A mass-media campaign aimed at the public and general practitioners in France significantly modified beliefs and behaviours about LBP.

Assessment of body perception disturbances in complex regional pain syndrome: A systematic review using the COSMIN guideline.

OBJECTIVE: To conduct a systematic review to identify which tools are being used to assess body perception disturbances in Complex Regional Pain Syndrome (CRPS) and to provide an evidence-based recommendation in the selection of an assessment tool, based on measurement properties. DATABASES AND DATA TREATMENT: Five electronic databases (EMBASE, Pubmed, PsycInfo, Science Direct and Web of Science) were searched for English or French written articles, with no time restrictions. All original articles using a body perception assessment tool with adult patients with CRPS were selected, regardless of their design (controlled trials, single case, qualitative study). Two investigators screened abstracts, selected full articles and extracted data independently. RESULTS: Thirty-eight full-text papers were obtained and three main methods to evaluate body perception disturbances were identified: The Bath Body Perception Disturbance Scale, the Neglect-like Symptoms questionnaire adapted from Galer and the patient's body perception description. No full psychometric assessments were found. The Limb Laterality Recognition Task was also used in conjunction with another method. CONCLUSIONS: Three main assessment methods for CRPS body perception disturbances are currently used. Full psychometric evaluation has not been completed for any of the assessment methods. As a consequence, we could not fully apply the COSMIN guideline. To date, there is no agreement concerning the use of a specific questionnaire or scale. The results indicate a need for further research such as psychometric properties of these questionnaires. SIGNIFICANCE: This systematic review identified body perception disturbances assessment methods and their the psychometric properties in order to provide help and guidance to researchers and clinicians to investigate those clinical features.

Is the Snoezelen method a non-pharmacological alternative for patients with neurocognitive disorders? / La méthode Snoezelen : une alternative thérapeutique chez les patients ayant des troubles cognitifs ?

Neuropsychiatric disorders are one of the frequent complications of neurocognitive disease, and have an impact on the quality of life of patients and caregivers. Non-phamacologic interventions are recommended as first-line treatment. The Snoezelen method is a multisensory stimulation method based on the assumption that acting on sensoriality can improve neuropsychiatric symptoms and thus quality of life, but its level of evidence is controversial. To explore this, we performed a systematic literature review of randomized controlled articles focusing on the use of the Snoezelen method in patients with cognitive disorders. Eighteen studies were included. The clinical outcomes studied were multiple (behavior, mood, cognition, functional capacities and biomedical parameters). When the Snoezelen method was compared to the "standard activities" group, it appears to be effective on short-term behavior. This was more negligible when the method was compared to others non-pharmacological interventions. Although the Snoezelen method could be effective on mood, cognition, and functional abilities, its level of evidence remains low. Furthers mixed studies (quantitative and qualitative) would be an interesting approach to delve into this topic in the most holistic way by integrating the patients, the caregivers and the cost of the method.

La prise en soin des symptômes neuropsychiatriques de patients ayant des troubles neurocognitifs est basée sur des traitements non médicamenteux. Certains auteurs suggèrent que la méthode Snoezelen pourrait être une alternative thérapeutique. L'objectif de cette revue de littérature était de faire une recherche systématique des essais contrôlés et randomisés ayant analysé l'effet de la méthode Snoezelen sur les patients âgés ayant des troubles cognitifs. Le processus de sélection a permis d'inclure 18 études, ayant des méthodologies hétérogènes. Dans plusieurs études, la méthode Snoezelen pourrait avoir un effet bénéfique, à court terme, sur les troubles du comportement, sur l'humeur, la cognition, ou les capacités fonctionnelles. Cependant, la méthode Snoezelen ne semblait pas être supérieure à d'autres interventions non médicamenteuses et certaines études montraient des résultats discordants. Finalement, le niveau de preuve d'efficacité de la méthode Snoezelen reste faible et des études mixtes (quantitatives et qualitatives) seraient intéressantes à mener pour évaluer l'intérêt de la méthode Snoezelen sur des profils spécifiques de patients ayant des troubles neurocognitifs.

Additional Benefit of Intraoperative Electroacupuncture in Improving Tolerance of Deep Brain Stimulation Surgical Procedure in Parkinsonian Patients.

BACKGROUND: Deep brain stimulation (DBS) is an effective technique to treat patients with advanced Parkinson's disease. The surgical procedure of DBS implantation is generally performed under local anesthesia due to the need for intraoperative clinical testing. However, this procedure is long (5-7 h on average) and, therefore, the objective that the patient remains co-operative and tolerates the intervention well is a real challenge. OBJECTIVE: To evaluate the additional benefit of electroacupuncture (EA) performed intraoperatively to improve the comfort of parkinsonian patients during surgical DBS implantation. METHODS: This single-center randomized study compared two groups of patients. In the first group, DBS implantation was performed under local anesthesia alone, while the second group received EA in addition. The patients were evaluated preoperatively, during the different stages of the surgery, and 2 days after surgery, using the 9-item Edmonton Symptom Assessment System (ESAS), including a total sum score and physical and emotional subscores. RESULTS: The data of nine patients were analyzed in each group. Although pain and tiredness increased in both groups after placement of the stereotactic frame, the ESAS item "lack of appetite", as well as the ESAS total score and physical subscore increased after completion of the first burr hole until the end of the surgical procedure in the control group only. ESAS total score and physical subscore were significantly higher at the end of the intervention in the control group compared to the EA group. After the surgical intervention (D2), anxiety and ESAS emotional subscore were improved in both groups, but the feeling of wellbeing improved in the EA group only. Finally, one patient developed delirium during the intervention and none in the EA group. DISCUSSION: This study shows that intraoperative electroacupuncture significantly improves the tolerance of DBS surgery in parkinsonian patients. This easy-to-perform procedure could be fruitfully added in clinical practice.

Multi-site rTMS with cognitive training improves apathy in the long term in Alzheimer's disease: A 4-year chart review.

OBJECTIVE: To assess the long-term effects of multi-site repetitive transcranial magnetic stimulation combined with cognitive training (NeuroAD procedure) on cognitive symptoms and apathy in patients with Alzheimer's disease (AD) as part of a 4-year chart review. METHODS: The study included the 30 AD patients who underwent NeuroAD treatment between 2015 and 2019 at our center. The clinical evaluation was based on the Mini Mental State Examination (MMSE), Alzheimer Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) and Apathy Inventory (AI). Assessment was performed before treatment (baseline), after an initial 6-week protocol of 30 sessions (M1.5), then 3 months (M3), 1 year (M12), and between 1.5 and 4 years (mean 28 months, M28) after treatment initiation. RESULTS: During the first year of follow-up, the AI score improved at all time points (M1.5, M3, M12, p < 0.0001), the ADAS-Cog score improved at the end of the initial procedure (M1.5, p = 0.003) then deteriorated (M12, p = 0.01), while the MMSE score did not change. At final assessment (M28), the AI score was still improved from baseline (p < 0.0001), while the MMSE and ADAS-Cog scores worsened (p < 0.0001). Regarding the ADAS-Cog score, the prolonged improvement at M12 or M28 was correlated with the initial improvement at M1.5. CONCLUSION: The NeuroAD procedure produced long-term improvement in apathy and more general cognitive improvement only in patients who responded well to the initial 6-week protocol. SIGNIFICANCE: Our results suggest long-term beneficial effects of the NeuroAD procedure on apathy, which need to be confirmed in controlled studies. The criteria for predicting a good outcome before starting the procedure remain to be defined.

Effects of COVID-19 lockdown on low back pain intensity in chronic low back pain patients: results of the multicenter CONFI-LOMB study.

PURPOSE: The COVID-19 pandemic and the extended lockdown are associated with numerous changes in behavior and lifestyles. The objective was to assess the impact of the first lockdown on LBP course among chronic LBP patients. METHODS: Descriptive and analytical, cross-sectional, multicenter study, conducted by questionnaire from mid-May to end of June 2020 among patients treated for chronic LBP in 6 French and 1 Swiss center. Collected data concerned changes in LBP intensity during lockdown, lockdown experience, physical activity (PA) practice and sedentary lifestyle prior and during lockdown, recourse to care, consumption of psychoactive substances for LBP, and professional activity and its conditions during lockdown. RESULTS: 360 participants (58.6% women, 52.1 ± 13.4 years) were included of which 65% were active (63% keep on working of which 54% teleworked). LBP got worse in 41.1%, mean VAS went from 49.5 ± 21.6 before to 53.5 ± 22.4 during lockdown (p < 0.001) and needed increase of treatment by 29% but very few people increased their consumption psychoactive substances for analgesia. Half of participants had well-experienced lockdown. Findings revealed a significant decrease in PA and increase of sedentary during lockdown (p < 0.0001). Good experience of lockdown was associated with LBP improvement (OR = 0.6 [0.3-0.9]) and decrease of PA with LBP worsening (OR = 1.9 [1.1-3.2]). Teleworking was also associated with LBP worsening. Gender, age, or BMI did not influence LBP course. CONCLUSION: These findings indicate that chronic LBP people suffered from increase in self-perceived LBP during lockdown and help to better understand the factors associated with their condition.

Repetitive transcranial magnetic stimulation for neuropathic pain: a randomized multicentre sham-controlled trial.

Repetitive transcranial magnetic stimulation (rTMS) has been proposed to treat neuropathic pain but the quality of evidence remains low. We aimed to assess the efficacy and safety of neuronavigated rTMS to the primary motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC) in neuropathic pain over 25 weeks. We carried out a randomized double-blind, placebo-controlled trial at four outpatient clinics in France. Patients aged 18-75 years with peripheral neuropathic pain were randomly assigned at a 1:1 ratio to M1 or DLPFC-rTMS and rerandomized at a 2:1 ratio to active or sham-rTMS (10 Hz, 3000 pulses/session, 15 sessions over 22 weeks). Patients and investigators were blind to treatment allocation. The primary end point was the comparison between active M1-rTMS, active DLPCF-rTMS and sham-rTMS for the change over the course of 25 weeks (Group × Time interaction) in average pain intensity (from 0 no pain to 10 maximal pain) on the Brief Pain Inventory, using a mixed model repeated measures analysis in patients who received at least one rTMS session (modified intention-to-treat population). Secondary outcomes included other measures of pain intensity and relief, sensory and affective dimensions of pain, quality of pain, self-reported pain intensity and fatigue (patients diary), Patient and Clinician Global Impression of Change (PGIC, CGIC), quality of life, sleep, mood and catastrophizing. This study is registered with ClinicalTrials.gov NCT02010281. A total of 152 patients were randomized and 149 received treatment (49 for M1; 52 for DLPFC; 48 for sham). M1-rTMS reduced pain intensity versus sham-rTMS (estimate for Group × Session interaction: -0.048 ± 0.02; 95% CI: -0.09 to -0.01; P = 0.01). DLPFC-rTMS was not better than sham (estimate: -0.003 ± 0.01; 95% CI: -0.04 to 0.03, P = 0.9). M1-rRMS, but not DLPFC-rTMS, was also superior to sham-rTMS on pain relief, sensory dimension of pain, self-reported pain intensity and fatigue, PGIC and CGIC. There were no effects on quality of pain, mood, sleep and quality of life as all groups improved similarly over time. Headache was the most common side effect and occurred in 17 (34.7%), 23 (44.2%) and 13 (27.1%) patients from M1, DLPFC and sham groups, respectively (P = 0.2). Our results support the clinical relevance of M1-rTMS, but not of DLPFC-rTMS, for peripheral neuropathic pain with an excellent safety profile.

Rehabilitation and lumbar surgery: the French recommendations for clinical practice.

BACKGROUND: Indications and techniques of rehabilitation differ widely across types of lumbar surgery, including timing (before or after surgery) and prescriptions (surgeons but also medical or paramedical professionals). OBJECTIVES: This project aimed to build consensual recommendations for practice in this context. METHODS: The SOFMER methodology was used to establish recommendations for physical medicine and rehabilitation: a steering committee defined the types of lumbar surgery involved and developed the main questions to be addressed; a scientific committee performed a literature review for grading evidence and proposed the first version of recommendations, which were discussed during a dedicated session at the national Physical and Rehabilitation Medicine congress; then an e-Delphi method with cross-professional experts was used to finalise recommendations and reach a multidisciplinary consensus. RESULTS: The main questions developed were the value of rehabilitation before and after surgery, timing and type of rehabilitation, benefit of supervision and instrumental rehabilitation, value of patient education, and complementary interventions concerning rehabilitation for discectomy, fusion, and disc prosthesis (excluding decompression for spinal stenosis). The literature review identified 60 articles, but for several of the questions, no article in the literature addressed the issue. The multidisciplinary scientific committee analysed the literature and addressed the questions to propose the first version of a set of 23 recommendations. The congress session failed to answer all questions or to reach consensus for all items. After a three-step e-Delphi, 20 recommendations were retained, for which consensus among experts was reached. The recommendations are applicable only to patients without a neurological lesion. CONCLUSIONS: These recommendations provide important and consensual knowledge to assist clinicians in decision-making for rehabilitation in lumbar surgery. Despite many of the recommendations relying exclusively on expert opinion rather than published evidence, this approach is an important advance to improve concordance among healthcare professionals.

Neuropathic pain in Mali: The current situation, comprehensive hypothesis, which therapeutic strategy for Africa?

INTRODUCTION: According to the taxonomy of the International Association for the Study of Pain (IASP 2011), neuropathic pain (NeuP) is defined as "pain caused by a lesion or disease of the somatosensory nervous system". NeuP is currently well-defined clinically, despite a high degree of etiological variation, and it has become a significant public health problem. This work aimed to study the situation regarding NeuP in current practice in Mali, as well as to analyze the therapeutic environment of the patients. METHODOLOGY: This was a retrospective and cross-sectional study, carried out in two phases: (1) compilation of the files of patients according to the ICD-11, over a period of 24 months (2) a second prospective phase regarding the Knowledge, Attitudes, and Practices (KAP) of general practitioners and neurologists in regard to NeuP. The focus of the first phase of the study was the files of the patients who had undergone a consultation at the Gabriel Touré UHC. The second phase of the study focused on the general practitioners (Community Health Centers (comHC) of Bamako) and neurologists (Malian or not). RESULTS: Over the period of the study, 7840 patients were seen in consultation in the Department of Neurology, of whom 903 for NeuP, thus amounting to a NeuP frequency of 11.5%. Women accounted for 58.9% (532/903), with a sex ratio of 1.4. Using a comparative normal law, the difference in frequency was statistically significant between males and females (p < 10-7) and between two age groups (p ã€ˆ10-3). The 49-58 years of age group was represented the most. Diabetic NeuP (21%), lumbar radiculopathies (14%), HIV/AIDS NeuP (13%), and post-stroke NeuP (11%) were the most represented. The survey among the carers revealed: a need for training, a low level of compliance with the therapeutic guidelines, and the use of traditional medicine by the patients. DISCUSSION/CONCLUSION: This work confirms that NeuP is encountered frequently in current practice, and its optimal management will involve specific training of carers and improvement of access to the medications recommended in this indication. In light of this issue, we revisit the debate regarding the concept of essential medications and the relevance of taking into account effective medications for the treatment of NeuP.

Diabetic polyneuropathy with/out neuropathic pain in Mali: A cross-sectional study in two reference diabetes treatment centers in Bamako (Mali), Western Africa.

INTRODUCTION: Diabetic polyneuropathy (DPN) with or without neuropathic pain is a frequent complication of diabetes. This work aimed to determine the prevalence of diabetic polyneuropathy, to describe its epidemiological aspects, and to analyze the therapeutic itinerary of patients with DPN. METHODS: This was a cross-sectional, descriptive study performed synchronously over six months at two major follow-up sites for patients with diabetes in Mali. DPN was diagnosed based on the Michigan Neuropathy Screening Instrument (MNSI). The neuropathic nature of the pain and the quality of life of patients were evaluated by the DN4 and the ED-5D scale, respectively. We used three (3) different questionnaires to collect data from patients (one at inclusion and another during the follow-up consultation) and from the caregivers of patients with DPN. RESULTS: We included 252 patients with diabetes, and DPN was found to have a healthcare facility-based prevalence of 69.8% (176/252). The sex ratio was approximately three females for every male patient. The patients were mostly 31 to 60 years of age, 83% had type 2 diabetes, and 86.9% had neuropathic pain Approximately half of the patients (48.3%) had autonomic neuropathy and they reported moderate to intense pain, which was mainly described as a burning sensation. The patients exhibited impaired exteroceptive and proprioceptive sensations in 51.7% of cases. The patients smoked tobacco in 3.4% of cases, while 36.6% of the patients were obese and had dyslipidemia. The caregivers clearly indicated that appropriate medications were not readily accessible or available for their patients with DPN. CONCLUSION: The healthcare facility-based prevalence of DPN with or without neuropathic pain was high in our cohort. These inexpensive and easy-to-use tools (MNSI, DN4) can be used to adequately diagnose DPN in the African context. In Mali, screening and early treatment of patients at risk of DPN should allow for a reduction of the burden of the disease, while caregivers need to be adequately trained to manage DPN.

Efficacy of Occipital Nerve Stimulation to Treat Refractory Occipital Headaches: A Single-Institution Study of 60 Patients.

BACKGROUND: Occipital nerve stimulation (ONS) is shown to be effective in treating various forms of headache. Most studies describe the treatment of occipital neuralgia (ON), but in many patients, the clinical description could also correspond to cervicogenic headache (CGH) or occipital migraine (OM). These different entities (ON, CGH, and OM) may be grouped together under the term occipital headaches. OBJECTIVE: To assess the efficacy of ONS to treat occipital headaches in a large series of patients with a long-term follow-up. MATERIALS AND METHODS: We performed a retrospective review of data on 60 patients with intractable occipital headaches treated with occipital nerve stimulation (ONS), who were referred to our center between October 2008 and October 2014. Details of pain evaluation, location, duration, cause and previous treatment were analyzed. Evaluations included the visual analog scale (VAS), the number of headache days per month (NHD), and the Medication Quantification Scale (MQS). Trials with transcutaneous electrical nerve stimulation (TENS-ONS) were performed and served as a guide for surgery indication (see Patients and Method section). RESULTS: After one year of ONS, mean VAS had decreased from 8.4/10 to 2.8/10 (72.2% reduction [p < 0.001]), and 76% of patients had at least a 50% decrease in mean VAS score. The mean MQS score decreased from 18 to 8.8, corresponding to a reduction of pain medication by an average of 50%. Adverse events concerned 12 patients (20%). Six patients presented with electrode displacement or fracture (10%) and six patients presented with cases of infection (10%) associated with the pulse generator. CONCLUSIONS: The results of this large series confirm that ONS is an effective treatment option for patients with intractable occipital headaches, but the frequency of complications remains quite high and must be taken into account in the surgical decision.

Multicenter, Prospective, Controlled Double-Blind Study Comparing Fib-19-01, A Phytotherapy Treatment, To A Dietary Supplement And To Conventional Care In Patients Suffering From Fibromyalgia.

BACKGROUND: Current therapeutic modalities for fibromyalgia (FM) do not provide satisfactory results and new approaches have to be explored. OBJECTIVES: To assess efficacy and safety of adding a phytotherapy treatment (Fib-19-01) to the current therapeutic regimen in patients with FM. METHODS: Double-blind controlled trial: women with active FM (Fibromyalgia Index Questionnaire FIQ > 40) were randomised to receive Fib-19-01 or a food supplement (FS) undistinguishable from Fib-19-01 or no supplementary treatment (NoST). All continued the conventional therapy throughout the 6 month follow-up. Primary endpoint: change in FIQ between Day 0 and month 6 (M6). Secondary Criteria: variation over time FIQ ( repeated measurements), change in Pichot fatigue scale, Pittsburgh Sleep Quality Index (PSQI), SF-12 and Hospital Anxiety and Depression (HAD) scales. RESULTS: 100 patients (Intent-To-Treat population) were analyzed. FIQ decreased significantly only in the Fib-19-01 group (P < .001) at both week 12 and 24. Improvement was higher for Fib-19-01 (-13.4 ± 18.9) than in the 2 other groups (-5.5 ± 15.6 and -5.6 ± 11.3) despite there was no statistical between-group difference at week 24 in FIQ score (P = .08 and P = .09 respectively). Analysis of variance in repeated measurements of FIQ showed a significant difference between Fib-19-01 and FS throughout the follow-up period (P = .03). Fib-19-01 was superior to both FS and NoST for Pichot scale decrease over time: -4.6 (range -6.9; -2.28), -0.29 (-2.7; 2.1) and -0.72 (-3.1; 1.66) (P = .013 and 0.023 respectively), mental and social SF12 [+8.1 (range 3.5; 12.6), -0.27(range -5.3; 4.8 ) and -0.02 (range -5.0; 4.9 ) P = .02 and 0.018)],HAD depression [-2.0 (range -3.3; -0.7), +0.5 (range -0.9; 1.9 ) and +0.71 (range -0.7; 2.1) P = .013 and 0.007]. No significant difference was found between FS and NoST groups for any outcome. All treatments were well and similarly tolerated. CONCLUSIONS: In patients with FM taking conventional therapy, Fib-19-01 has a therapeutic effect on fatigue, emotion and social life, and depression associated with the disease.

The Value of High-Frequency Repetitive Transcranial Magnetic Stimulation of the Motor Cortex to Treat Central Pain Sensitization Associated With Knee Osteoarthritis.

AIM: Chronic pain associated with knee osteoarthritis may develop in connection with a maladaptive process of pain sensitization in the central nervous system. Repetitive transcranial magnetic stimulation (rTMS) has been proposed to treat various pain syndromes related to central sensitization phenomenon, but was never applied in the context of knee osteoarthritis. METHODS: A 71-year-old woman presenting clinical evidence of central sensitization of pain associated with left knee osteoarthritis underwent monthly sessions of rTMS delivered at 10 Hz over the right motor cortex. RESULTS: From the week following the third session, she began to improve on various clinical aspects, including pain. After 10 sessions (i.e., almost one year of follow-up), pain was reduced by 67%, especially regarding neuropathic components, while sleep disorders and fatigue also improved by 57-67%. The central sensitization inventory (CSI) score was reduced by 70%. CONCLUSION: This observation suggests that high-frequency motor cortex rTMS could be a therapeutic option to treat neuropathic pain and psychological symptoms associated with central sensitization developing in the context of chronic osteoarthritis of the knee joint.
