The objective of this systematic review was to compare the analgesic effectiveness and safety profile of LDK and morphine for acute pain management in the ED. METHODS: Electronic searches of Medline and EMBASE were conducted and reference lists were hand-searched. Randomized controlled trials (RCTs) comparing LDK to morphine for acute pain control in the ED were included...

Spinal injury is among the most severe and feared injuries an athlete may face. We present an up-to-date review of the recent literature, stratifying recommendations based on injury location (cervical, thoracic, and lumbar spine) and type, as well as, the level of competitive play (high school, collegiate, professional). A literature search was completed to identify all publications reporting return to play guidelines for athletic injuries or injury-related surgery irrespective of the study design. Publication dates were not restricted by year...

Epigastric pain and dyspepsia are common presenting complaints to the emergency department and are typically treated with a variety of antacids, antihistamines, proton pump inhibitors, or anticholinergics. Prior studies have shown mixed results for acute dyspepsia management, which raises the question as to the optimal analgesic therapy. This study compares antacid monotherapy with two combinations of lidocaine with antacid in the treatment of dyspepsia.

BACKGROUND: Symptomatic haemorrhoids affect a large number of patients throughout the world. The aim of this systematic review was to compare the surgical outcomes of stapled haemorrhoidopexy (SH) versus open haemorrhoidectomy (OH) over a 20-year period. METHODS: Randomized controlled trials published between January 1998 and January 2019 were extracted from Pubmed using defined search criteria. Study characteristics and outcomes in the form of short-term and long-term complications of the two techniques were analyzed...

One maladaptive consequence of inflammatory stimulation of the afferent somatosensory system is the manifestation of inflammatory pain. We established and characterized a neuroglial primary culture of the rat superficial dorsal horn (SDH) of the spinal cord to test responses of this structure to neurochemical, somatosensory, or inflammatory stimulation. Primary cultures of the rat SDH consist of neurons (43%), oligodendrocytes (35%), astrocytes (13%), and microglial cells (9%). Neurons of the SDH responded to cooling (7%), heating (18%), glutamate (80%), substance P (43%), prostaglandin E2 (8%), and KCl (100%) with transient increases in the intracellular calcium [Ca2+ ]i ...

Acetaminophen is the only medication recommended for pain and fever management during pregnancy. However, studies have reported an association between in utero acetaminophen and neurocognitive disorders later in life. Additionally, acetaminophen has been shown to have endocrine disrupting properties altering hormones critical for normal fetal development. As the placenta is an endocrine organ that produces hormones for fetal development, any attempts to elucidate the mechanism underlying in utero acetaminophen and birth outcomes must also focus on the placenta...

Internet-based interventions for chronic pain have demonstrated efficacy and may address access barriers to care. Participant characteristics have been shown to affect engagement with these programs; however, limited information is available about the relationship between participant characteristics and engagement with internet-based programs for self-management of chronic pain. The current study examined relationships between demographic and clinical characteristics and engagement with the Pain EASE program, a self-directed, internet-based cognitive behavioral therapy intervention for veterans with chronic low back pain (cLBP)...

INTRODUCTION: Complex regional pain syndrome (CRPS), formerly known as reflex sympathetic dystrophy (RSD), is a difficult to treat condition characterized by debilitating pain and limitations in functional ability. Neuromodulation, in the form of spinal cord stimulation (SCS) and peripheral nerve stimulation (PNS), have been traditionally used as a treatment for CRPS with variable success. OBJECTIVE: This chart review describes the use of implantable PNS systems in the treatment of CRPS of the upper and lower extremities spanning nearly three decades...

OBJECTIVES: To determine the differences in psychological states and sleep quality in patients with various Temporomandibular disorder (TMD) subtypes, and to ascertain the relationships between TMD duration with psychological and sleep impairments. METHODS: A total of 830 TMD patients were recruited categorized into pain-related (PT), intra-articular (IT), and combined (CT) TMD groups. Each group was further divided into acute and chronic subtypes. The Depression, Anxiety, Stress Scales-21 (DASS-21), and Pittsburgh Sleep Quality Index (PSQI) were used to assess emotional states and sleep problems...

Athletic groin pain (AGP) is a chronic, painful condition which is prevalent in players of field sports that require rapid changes of direction. Following successful rehabilitation, systematic changes have been observed in the kinetics and kinematics of pre-planned change of direction manoeuvres, providing insight into potential foci for rehabilitation monitoring and for the assessment of interventions. However, changing direction in field sports is often reactive rather than pre-planned, and it is not known whether such post-rehabilitation changes are seen in reactive manoeuvres...

Dentists stand in an optimal position to prevent and manage patients suffering from chronic orofacial pain (OFP) disorders, such as temporomandibular disorders, burning mouth syndrome, trigeminal neuralgia, persistent idiopathic dentoalveolar pain, among others. However, there are consistent reports highlighting a lack of knowledge and confidence in diagnosing and treating OFP among dental students, recent graduates, and trained dentists, which leads to misdiagnosis, unnecessary costs, delay in appropriate care and possible harm to patients...

BACKGROUND: We aimed to analyze the feasibility and risk factors associated with early mobilization (EM) within 4 h after thoracoscopic lobectomy and segmentectomy. METHODS: This study retrospectively evaluated 214 consecutive patients who underwent thoracoscopic anatomical pulmonary resection using our EM protocol between October 2017 and February 2019. We compared the correlations of the patients' characteristics including the total number of drugs and perioperative parameters such as air leak, and orthostatic hypotension (OH) between the EM (E group) and failed EM (F group) groups...

PURPOSE OF REVIEW: Multimodal pain management is the most effective way to treat postsurgical pain. However, the use of opioids for acute pain management has unfortunately been a significant contributor to the current opioid epidemic. The use of opioids should be limited and only considered a "rescue" pain medication after other modalities of pain management have been utilized. RECENT FINDINGS: It may be difficult to curtail the use of opioids in the treatment of chronic pain; however, in the postsurgical setting, there is compelling evidence that an opioid-centric analgesic approach is not necessary for good patient outcomes and healthcare cost benefits...

OBJECTIVE: The goal of this study was to compare the effects of ibuprofen and low-level laser therapy in alleviating orthodontic pain observed after elastomeric separator placement (ESP) by means of the analysis of interleukin 1‑beta (IL-1β) and substance P (SP) levels in gingival crevicular fluid (GCF) and visual analog scale (VAS). MATERIALS AND METHODS: A total of 60 subjects requiring ESP for the banding of maxillary first molars were randomly assigned to the ibuprofen, laser, and control groups...

OBJECTIVES: Synovitis in symptomatic knee OA (KOA) is common and is associated with joint symptoms. Optimal synovial measurement on MRI is, however, unclear. Our aims were to examine the relationship between MRI measures of synovitis and knee symptoms in symptomatic KOA. METHODS: Data from a randomized, multicentre, placebo-controlled trial (UK-VIDEO) of vitamin-D therapy in symptomatic KOA were utilized. Participants reported knee symptoms using WOMAC at baseline and annually...

The cannabinoid receptor type 1 (CB1) plays critical roles in multiple physiological processes such as pain perception, brain development and body temperature regulation. Mutations on this gene (CNR1), results in altered functionality and/or biosynthesis such as reduced membrane expression, changes in mRNA stability or changes in downstream signaling that act as triggers for diseases such as obesity, Parkinson's, Huntington's, among others; thus, it is considered as a potential pharmacological target. To date, multiple quantification methods have been employed to determine how these mutations affect receptor expression and localization; however, they present serious disadvantages that may arise quantifying errors...
