Two statements from national organizations outline recommended minimum effective doses of gabapentin and pregabalin for the treatment of diabetic peripheral neuropathy (DPN). However, studies of real-world gabapentinoid dosing demonstrate that the recommended dose targets are frequently not met and do not consider renal insufficiency. This study aimed to characterize gabapentinoid prescribing patterns in patients receiving primary care at two internal medicine clinics within an academic medical center. This retrospective chart review included adult outpatients who were newly initiated on gabapentin or pregabalin between October 1, 2017 and October 1, 2020 and reviewed for 12 months. A total of 1,221 patients were included in the study with 1,079 (88.4%) prescribed gabapentin and 142 (11.6%) prescribed pregabalin. Only 22.4% of patients prescribed gabapentin and 33.3% of patients prescribed pregabalin with adequate renal function met the minimum effective dosing of gabapentin 1800 mg per day and pregabalin 300 mg per day provided by the American Diabetes Association (ADA) and American Academy of Neurology (AAN). This study supports the need for optimization of gabapentinoid dosing to ensure an adequate trial at the minimum effective dose is completed.
More than 1 billion people live with chronic pain, including 100 million Americans, with a majority utilizing prescription and over-the-counter (OTC) pain medications. OTC medications are readily available and facilitate generally positive efficacy, yet misuse leads to a high number of medication-related problems, with acetaminophen alone accounting for more than 50,000 emergency department visits annually. The West Virginia Health Sciences and Technology Academy (HSTA) high school student program and the West Virginia University Health Sciences Center collaborated to accomplish 2 objectives: to assess and compare knowledge and perceptions of OTC pain medications in the West Virginia community and to develop and provide educational interventions to high school students regarding knowledge and perceptions of OTC pain medications. Resulting student knowledge data illustrated a statistically significant improvement in knowledge. Community survey screening data resulted in 85% answering two-thirds of the knowledge questions incorrectly, with 12% (140 of 1174 participants) answering every single knowledge survey question incorrectly. These data strongly exhibit not only the incredible need for OTC pain medication community education but also that this study's educational methods were very effective at teaching high school students, with possible applicability to the entirety of society.
The UK Medical Cannabis Registry is the largest real world data platform for medical cannabis outcomes in the UK, providing insight into clinical outcomes and monitoring safety of this novel therapy. This study aims to assess the functionality and accessibility of the online data collection platform and patient priorities for future research. Descriptive statistics were used to analyze quantitative data. For open-ended questions an inductive thematic analysis was performed. 600 responses were recorded. 554 (92.3%) patients had used the platform. 272 (90.4%) patients believed it was easy to input medications. 52 (8.67%) patients recorded an adverse event with 38 (73.1%) finding it easy to record. 535 (96.6%) patients had completed health questionnaires with 490 (91.6%) patients finding this easy to do. 553 (92.2%) patients agreed that contributing to the registry would impact the medical care of future patients. "Assessing the impact of medical cannabis on quality of life generally" was the top research priority for 357 (59.3%) patients. This study demonstrates that most enrolled patients found the platform easy to use and believed they were positively impacting future medical cannabis patient care. Future patient research priorities included assessment of quality of life and condition-specific outcomes.
Objective: Painful Phantom Limb Syndrome (PPLS) occurs in 50 to 80% of patients undergoing amputation, having a great impact on quality of life, productivity and psychosocial sphere. The objective of this review is to summarize the pharmacological and non-pharmacological strategies, surgical optimization, and provide a multidisciplinary approach aimed at reducing the incidence of chronic pain associated with PPLS in patients undergoing limb amputation.
Methods: A narrative review was carried out using Medline, Pubmed, Proquest, LILACS and Cochrane, searching for articles between 2000 and 2021. Articles describing the epidemiology, pathophysiological considerations, and current treatments were selected after a screening process.
Results: A multidisciplinary and multimodal approach is required in PPLS, and should include the use of regional techniques, and adjuvants such as NSAIDs, ketamine, lidocaine and gabapentinoids. In addition, an evaluation and continuous management of risk factors for chronic pain in conjunction with the surgical team is necessary.
Conclusion: The current literature does not support that a single technique is effective inthe prevention of PPLS. However, adequate acute pain control, rehabilitation and early restoration of the body scheme under a multidisciplinary and multimodal approach have shown benefit in the acute setting.
Gabapentin (GBP) is a structural analog of gamma-aminobutyric acid (GABA) that is commonly used in palliative care for symptom management indications including neuropathic pain syndromes, hiccups, cough, and anxiety. An uncommon adverse effect of GBP is urinary incontinence (UI). We report the case of a 61-year-old male with metastatic non-small cell lung cancer who developed probable overflow UI while receiving 1200 mg/day of GBP for chemotherapy-induced peripheral neuropathy. The patient self-tapered GBP to 600 mg/day which resolved the overflow UI, but resulted in poorly controlled bilateral foot pain. The palliative care physician rotated the patient to pregabalin 150 mg/day and his bilateral foot pain improved after his regimen was titrated to 200 mg/day. The patient did not experience overflow UI while taking pregabalin despite the similar pharmacology and comparable doses to GBP. We believe this is the first case report to describe subsequent achievement of pain control by substituting pregabalin without recurrence of UI. Healthcare professionals should consider GBP as a potential cause when evaluating patients presenting with new onset overflow UI.
Post-herpetic neuralgia (PHN) is an entity derived from peripheral nerve damage that occurs during the reactivation of the Varicella Zoster Virus (VZV), which manifests itself through pain with neuropathic characteristics. This can prove to be very difficult to manage in the chronic stages of disease reappearance. There currently exists a multitude of treatment alternatives for PHN, however, prevention through the early initiation of antiviral regimens is vital. There are various pharmacological options available, but it is important to individualize each patient to maximize efficacy and minimize adverse effects. Interventional procedures have become a cornerstone in difficult-to-manage cases, and have shown promising outcomes when used in a multimodal approach by experienced specialists. It is necessary to make an objective diagnosis of PHN and start early treatment. Additionally there is current evidence that vouches for interventional therapies as well as individualization, with a clear establishment of therapeutic objectives according to the needs of each patient.
