Differences between the healthcare systems of Quebec and France for the treatment of pain due to spinal disorders.

In Quebec, Canada, the public healthcare system offers free medical services. However, patients with spinal pain often encounter long waiting times for specialist appointments and limited physiotherapy coverage. In contrast, private clinics provide expedited care but are relatively scarce and entail out-of-pocket expenses. Once a patient with pain caused by a spinal disorder meets a pain medicine specialist, spinal intervention is quickly performed when indicated, and patients are provided lifestyle advice. Transforaminal epidural steroid injections are frequently administered to patients with radicular pain, and steroid injections are administered on a facet joint to control low back or neck pain. Additionally, medial branch blocks are performed prior to thermocoagulation. France's universal healthcare system ensures accessibility at controlled costs. It emphasizes physical activity and provides free physical therapy services. However, certain interventions, such as transforaminal and interlaminar epidural injections, are not routinely used in France owing to limited therapeutic efficacy and safety concerns. This underutilization may be a potential cause of chronic pain for many patients. By examining the differences, strengths, and weaknesses of these two systems, valuable insights can be gained for the enhancement of global spinal pain management strategies, ultimately leading to improved patient outcomes and satisfaction.

Protocol for lower back pain management: Insights from the French healthcare system.

In this editorial we comment on the article published in a recent issue of the World Journal of Clinical Cases. This article described a novel ultrasound-guided lateral recess block approach in treating a patient with lateral recess stenosis. The impact of spinal pain-related disability extends significantly, causing substantial human suffering and medical costs. Each county has its preferred treatment strategies for spinal pain. Here, we explore the lower back pain (LBP) treatment algorithm recommended in France. The treatment algorithm for LBP recommended by the French National Authority for Health emphasizes early patient activity and minimal medication use. It encourages the continuation of daily activities, limits excessive medication and spinal injections, and incorporates psychological assessments and non-pharmacological therapies for chronic cases. However, the algorithm may not aggressively address acute pain in the early stages, potentially delaying relief and increasing the risk of chronicity. Additionally, the recommended infiltrations primarily involve caudal epidural steroid injections, with limited consideration for other injection procedures, such as transforaminal or interlaminar epidural steroid injections. The fixed follow-up timeline may not accommodate patients who do not respond to initial treatment or experience intense pain, potentially delaying the exploration of alternative therapies. Despite these limitations, understanding the strengths and weaknesses of the French approach could inform adaptations in LBP treatment strategies globally, potentially enhancing patient outcomes and satisfaction across diverse healthcare systems.

Neurological Soft Signs and Post-Traumatic Stress Disorder: A Biomarker of Severity?

BACKGROUND: The psychophysiological changes for individual suffering from chronic post-traumatic stress disorder (PTSD) raise to the questions of how facilitate recovery and return to work. Negative alterations in neuro-cognition remain a complaint for patients and participate to long-term functional impairments. Neurological soft signs (NSSs) appear as a candidate for better understanding these complaints. They have been reported in several mental disorders. They are found in several behavioral and/or neurocognitive disorders and are taken into account by psychiatric rehabilitation programs to support recovery. As few studies evaluate NSSs in PTSD, our exploratory study aims to assess NSSs in chronic PTSD and their relationships with PTSD severity. METHOD: Twenty-two patients with a clinical diagnosis of chronic PTSD were evaluated in terms of PTSD severity (post-traumatic checklist scale, PCL5), NSSs (NSSs psychomotor skills scale, PASS), and well-being upon arrival to the hospital and compared with 15 healthy subjects. Statistical non-parametric analyses assessed the relationships between these variables. RESULTS: PTSD subjects exhibited higher NSSs compared with healthy subjects. NSSs were positively associated with PTSD severity, with negative alterations in cognition and mood, and with impairment in well-being. They were higher in women compared with men. No impact of age was found. Three groups were identified based on the severity of the PTSD. Severe PTSD exhibited NSSs characterized by motor integration alterations. CONCLUSIONS: This pilot study suggests that NSSs might be a biomarker of PTSD severity. This proof of concept highlights the need for further research for better evaluating the clinical neuro-functional impairment. This will be helping for defining neurological remediation for promoting PTSD recovery.

Rhythmic fluctuations of saccadic reaction time arising from visual competition.

Recent research indicates that attentional stimulus selection could be a rhythmic process. In monkey, neurons in V4 and IT exhibit rhythmic spiking activity in the theta range in response to a stimulus. When two stimuli are presented together, the rhythmic neuronal responses to each occur in anti-phase, a result indicative of competitive interactions. In addition, it was recently demonstrated that these alternating oscillations in monkey V4 modulate the speed of saccadic responses to a target flashed on one of the two competing stimuli. Here, we replicate a similar behavioral task in humans (7 participants, each performed 4000 trials) and report a pattern of results consistent with the monkey findings: saccadic response times fluctuate in the theta range (6 Hz), with opposite phase for targets flashed on distinct competing stimuli.
