Nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin, have been associated with the damage to the gastrointestinal tract. One proposed mechanism of injury to the gastrointestinal mucosa by NSAIDs is oxygen radical-dependent microvascular injury. There is reasonable evidence to support the benefit of the addition of ascorbic acid, an ingredient with antioxidant properties, to moderate the adverse gastrointestinal (GI) effects of aspirin. ⋯ The existing body of evidence is relevant to short-term therapy with analgesic aspirin doses, and extrapolation to long-term therapy with low-dose aspirin is not appropriate. The purported benefit of an aspirin and ascorbic acid combination is a local observance and is not suspected to influence the adverse GI effects experienced as a result of systemic prostaglandin inhibition. Nevertheless, ascorbic acid may be a viable addition to the strategies employed to improve the gastrointestinal tolerability of aspirin.

Neurogenic claudication due to symptomatic lumbar spinal stenosis (LSS) is a painful condition causing significant functional disability. While the cause of LSS is multifactorial, thickened ligamentum flavum (LF) accounts for up to 85% of spinal canal narrowing. mild percutaneous lumbar decompression allows debulking of the hypertrophic LF while avoiding the morbidities frequently associated with more invasive surgical procedures. ⋯ This study demonstrated significant functional improvement as well as decreased disability secondary to neurogenic claudication after mild procedure. Safety, cost-effectiveness, and quality-of-life outcomes are best compared with comprehensive medical management in a randomized controlled fashion and, where ethical, to open lumbar decompression surgery.

Retrospective cohort study. ⋯ Nonmechanical findings during a traditional movement screen are not specific to sinister conditions such as metastatic spinal cancer. Clinicians should expect concomitant conditions to exhibit painful or limited findings in patients with and without cancer.

Among persons in current HIV outpatient care, data on opioid prescribing are lacking. This study aims to evaluate predictors of repeat opioid prescribing and to characterize outpatient opioid prescribing practices. ⋯ Advanced HIV disease and greater medical and neuropsychiatric comorbidity predict repeat opioid prescribing, and these findings reflect the underlying complexities in managing pain symptoms in this population. We also highlight multiple deficiencies in opioid prescribing practices and nonadherence to guidelines, which are of concern as effective and safe pain management for our HIV-infected population is an optimal goal.

Modulation of somatosensory profiles by spinal cord stimulation in primary Raynaud's syndrome.
Spinal cord stimulation (SCS) is an effective antinociceptive treatment for various neuropathic pain syndromes. Apart from antinociceptive action, it may modulate overall somatosensory perception. This case report targets the question of whether SCS may alter quantitative sensory testing (QST) in a patient with primary Raynaud's syndrome. ⋯ SCS significantly modulated the somatosensory profile in a patient with primary Raynaud's syndrome. These effects were pronounced in qualities involving Aβ, C, and A∂ nerve fibers. Further investigations may help to understand the mechanisms of action of SCS.
