OBJECTIVE: To perform a systematic review of clinical practice guidelines (CPGs) covering the management of common shoulder disorders. DATA SOURCES: A systematic search of CPGs on specific shoulder disorders was conducted up to August 2022 in relevant databases. STUDY SELECTION: Twenty-six CPGs on rotator cuff (RC) tendinopathy, RC tear, calcific tendinitis, adhesive capsulitis, glenohumeral (GH) instability, GH osteoarthritis, or acromioclavicular disorders published from January 2008 onward were screened and included...

Pain regimens, particularly for chronic cancer and noncancer pain, must balance the important analgesic benefits against potential risks. Many effective and frequently used pain control regimens are associated with iatrogenic adverse events. Interventional procedures can be associated with nerve injuries, vascular injuries, trauma to the spinal cord, and epidural abscesses. Although rare, these adverse events are potentially catastrophic. Pharmacologic remedies for pain must also consider potential side effects that can occur even at therapeutic doses of over-the-counter remedies such as paracetamol (acetaminophen) or nonsteroidal anti-inflammatory drugs...

Whether through minimally invasive or conventional open techniques, thoracic surgery is often reported to be one of the most painful surgical procedures due to the incision of intercostal and respiratory muscles, rib injury or resection, and placement of surgical drains. Some of the more severe complications related to poor analgesia include prolonged intensive care unit stay, mechanical ventilation, pneumonia, and the development of chronic postoperative pain syndromes. Over the past few decades, much progress has been made in recognizing the importance of multimodal analgesic techniques...

BACKGROUND: Cerebrospinal fluid (CSF) can reasonably be hypothesized to mirror central nervous system pathophysiology in chronic pain conditions. Metabolites are small organic molecules with a low molecular weight. They are the downstream products of genes, transcripts and enzyme functions, and their levels can mirror diseased metabolic pathways. The aim of this metabolomic study was to compare the CSF of patients with chronic neuropathic pain ( n = 16) to healthy controls ( n = 12). METHODS: Nuclear magnetic resonance spectroscopy was used for analysis of the CSF metabolome...

The pathophysiology of osteoarthritis (OA) involves the destruction of articular cartilage and the overgrowth of bone with lipping and spur formation. Nerve endings in the joint capsule and adjacent tissues play a major role in the pain mechanisms of osteoarthritis. This often requires patients to seek pain control measures beyond over-the-counter drugs, such as local anesthetics. Osteopathic manipulation treatment (OMT) is a conservative, non-pharmacological treatment that can be used to help treat chronic pain associated with OA...

STUDY DESIGN: Randomized, double-blinded, placebo-controlled trial. OBJECTIVE: Examine the effect of intravenous ketorolac (IV-K) on hospital opioid use compared to IV placebo (IV-P) and IV acetaminophen (IV-A). SUMMARY OF BACKGROUND DATA: Controlling postoperative pain while minimizing opioid use following lumbar spinal fusion is an important area of study. METHODS: Patients aged 18-75 years undergoing 1-2 level lumbar fusion between April 2016 - December 2019 were included...

It remains a clinical challenge identifying when joint hypermobility (JH) is responsible for pain. Previous nomenclature utilized terms such as (benign) joint hypermobility syndrome (JHS) but this was updated in 2017 as advances in genetics provide a basis for nearly all variants of Ehlers-Danlos syndrome (EDS) with the exception of hypermobile EDS (hEDS). New terminology describes hypermobility spectrum disorders (HSDs) as the updated term for JHS. Diagnosis of a subtype of HSDs should be considered in patients who have JH coupled with the presence of secondary musculo-skeletal manifestations (trauma, chronic pain, disturbed proprioception, and other manifestations) and at the exclusion of hEDS...

Paracetamol (acetaminophen) is an extensively used analgesic for acute and chronic pain management. Currently, paracetamol is manufactured for oral, rectal, and intravenous (IV) use. Research has shown varied results on the analgesic properties of IV paracetamol compared to oral and rectal paracetamol; however, research on the same doses of paracetamol is limited. Therefore, this review was constructed to explore the analgesic properties of IV paracetamol compared with oral and rectal paracetamol administered in equivalent doses...

Introduction: The use of opioids has increased markedly in the past decades in European countries, especially for treatment of non-cancer pain including painful chronic musculoskeletal conditions. However, there are some notable differences in the relative levels of use between geographical areas and some distinct, context-specific patterns of weak and strong opioid use. The aim of this work is to describe real world trends in dosage forms and population exposure in the prescription opioid use on isolated geographically area: The Canary Islands of Gran Canaria, Lanzarote and Fuerteventura, Spain...

INTRODUCTION: Chronic pain is a common symptom of rheumatic diseases that impacts patients' quality of life. While non-pharmacological approaches are often recommended as first-line treatments, pharmacological interventions are important for pain management. However, the effectiveness and safety of different pharmacological treatments for chronic pain in rheumatic diseases are unclear. METHODS: This review critically synthesizes the current evidence base to guide clinicians in selecting appropriate pharmacological treatments for their patients, considering the expected benefits and potential risks and side effects...

BACKGROUND AND PURPOSE: The aim of the present systematic review was to investigate the effectiveness of pharmacological and non-pharmacological therapy on pain intensity and disability in older people with chronic nonspecific low back pain. METHODS: Searches were conducted in the MEDLINE, COCHRANE LIBRARY, EMBASE, AMED, PSYCINFO, and PEDRO databases up to 2022. Risk of bias was appraised using the Cochrane Risk of Bias 2.0 tool. Estimated mean differences and respective 95% confidence intervals were presented for each paired comparison and the strength of the current evidence was assessed using the GRADE approach...

BACKGROUND: Dysmenorrhea, or painful menstrual periods, is one of the most common gynecological complaints. Most reports of uterine contractions range between moderate to severe pain, and patients often elect to cope with their discomfort without assistance from a physician. In the process, women experiencing dysmenorrhea are more likely to report absenteeism from work and school. OBJECTIVES: This study measures the reported impact of dysmenorrhea on patients' lives and elucidates a relationship between income and access to oral contraceptives...

BACKGROUND: Chronic low back pain (CLBP) is a global health problem, and gabapentin and pregabalin are often used in the treatment of patients without associated radiculopathy or neuropathy. Therefore, determining their efficacy and safety is of enormous value. OBJECTIVE: To examine the efficacy and safety of using gabapentin and pregabalin for CLBP without radiculopathy or neuropathy. METHODS: We performed a search on the CENTRAL, MEDLINE, EMBASE, LILACS, and Web of Science data bases for clinical trials, cohorts, and case-control studies that evaluated patients with CLBP without radiculopathy or neuropathy for at least eight weeks...

Despite being an essential part of whole-person care, patients with cancer often experience complex and under-treated pain. Managing cancer-related pain in patients who are also pregnant compounds the challenge for adequate pain management, as studies have largely excluded this population. Therapy for pain management should be guided by the cause and mechanism of pain. The objective of this review is to provide clinicians with an understanding of pain experienced by pregnant patients with cancer and medications that may be used to help manage cancer-related pain...

While opioid prescribing has significantly decreased from a peak in 2012, less is known about the national utilization of non-opioid analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen (APAP) in the context of the opioid crisis. The objective of this study is to characterize the prescribing trends of NSAIDs and APAP in the US ambulatory care setting. We conducted repeated cross-sectional analyses using the 2006-2016 National Ambulatory Medical Care Survey. NSAID-involved visits were defined as patient visits among adults in which NSAIDs were ordered, supplied, administered, or continued...
