Changes in analgesic prescribing among older adults hospitalised for osteoarthritis or joint replacements

Abstract Introduction Osteoarthritis is a chronic, progressive joint disease, associated with frequent pain, and functional decline. The primary risk factor for developing osteoarthritis is advanced age. Older patients are more susceptible to the adverse effects of commonly prescribed analgesics such as opioids and non-steroidal anti-inflammatory drugs (NSAIDs), owing to a greater prevalence of comorbidities and age-related changes in this cohort. The analgesic burden and prescribing trends in this cohort are largely unknown in the Irish context despite their increased susceptibility to adverse effects. Aim This study aims to evaluate analgesic prescribing patterns before and after an osteoarthritis or joint arthroplasty related hospital admission in patients aged ≥65 years and to identify factors associated with long-term prescribing of opioids and oral NSAIDs post-discharge. Methods This was an observational study of older adults with an osteoarthritis or joint arthroplasty hospitalisation. Data were collected for a larger study from 44 general practices in Ireland from 2012-2018 and included general practice records (12 months pre/post-index hospitalisation) and hospital discharge summaries, which was extracted as anonymous data from the practice software system. The analysis described prevalence of use of analgesics in the 12 months pre and post their hospitalisation. To assess long-term prescribing, multivariable analysis assessed discharge prescription and patient characteristics associated with opioid and oral NSAID use 3-12 months post-discharge. Results Overall, 738 individuals were included (52.9% female, mean age 78.1 years). Compared to 12 months pre-hospitalisation, patients were less likely to be prescribed a weak opioid or oral NSAID from discharge to 3 months post-discharge, or in the 3-12 months post-discharge. For strong opioids, prescribing was significantly less likely in the 3-12 months post-discharge compared to pre-discharge (odds ratio (OR) 0.54, 95%CI 0.40-0.74). Female sex (OR 1.61, 95%CI 1.10-2.36), strong opioid prescribing at discharge (OR 2.47, 95%CI 1.56-3.90) and pregabalin discharge prescribing (OR 2.21, 95%CI 1.12-4.33) were significantly associated with long-term strong opioid prescribing 3-12 months post-discharge. For oral NSAID prescribing, lower age (OR 0.97, 95%CI 0.95-1.00), female sex (OR 1.56, 95%CI 1.08-2.25), and discharge prescribing of strong opioids (OR 1.94, 95%CI 1.23-3.04) were significantly associated. Conclusion The use of opioids and oral NSAIDs is typically reduced for patients post-discharge from an osteoarthritis or joint arthroplasty hospitalisation. Female sex and strong opioids at discharge are associated with the prescribing of strong opioids and oral NSAIDs. Although our study was limited by use of prescription records which may not accurately represent what was dispensed or utilised by patients, it is the first to examine changing patterns of analgesic prescribing among osteoarthritis/joint arthroplasty patients. This contributes knowledge on modifiable characteristics which could reduce long-term use of these medications where appropriate.

OA42 Effect of intra-articular corticosteroid injections for osteoarthritis on subsequent use of pain medications: an instrumental variable and propensity score analysis

Abstract Background/Aims Intra-articular corticosteroid injections (IACI) are recommended in the UK by NICE as an adjunctive treatment for uncontrolled pain from osteoarthritis (OA). NICE guidance states there is no evidence for therapeutic benefit lasting beyond three months, and that more evidence is needed on effectiveness at non-knee joints. We therefore aimed to assess the longer-term effect of IACI use on pain medication prescriptions among people with hand, hip, knee or shoulder OA. Methods We conducted a cohort study using UK primary care (CPRD GOLD) data for patients aged ≥20 years with a first diagnosis of OA during 2005-2019, excluding those with prior orthopaedic surgery referral or OA diagnosed at multiple joints. Exposure to IACI was defined using Read codes. The primary outcome was incident prescribing of pain medication: oral non-steroidal anti-inflammatory drugs (NSAIDs), opioids, oral corticosteroids, paracetamol, partial opioids, and topical NSAIDs. In main analyses, an instrumental variable (IV) approach was used. Index date was six months after OA diagnosis date and IV was defined as practice preference for IACI use in the year prior to index date (single and recurrent use considered separately). Outcomes were measured over five years from index date. Covariate balance was assessed, and two-step Poisson regression used where assumptions met. In secondary analyses, propensity score (PS) matching was carried out and time-varying exposure Cox models used to estimate treatment effect. Results Of 181,818 eligible patients, 92,157 (50.7%) were retained in IV analyses of single IACI and 89,103 (49.0%) of repeat IACI. Covariates were well balanced (SMD ≤0.1) across IV groups for hand (single IACI only) and knee OA, but not hip or shoulder OA. In IV analyses of hand OA, single IACI was associated with lower 5-year cumulative incidence of several pain medications including oral corticosteroids (relative risk [RR] 0.27 [95% CI 0.10, 0.76], paracetamol (RR 0.27 [0.09, 0.78] and partial opioids (RR 0.24 [0.10, 0.60]). IACI for knee OA was associated with lower 5-year cumulative incidence of most pain medications, e.g., for partial opioids a RR 0.46 [95% CI 0.34, 0.61] and RR 0.33 [0.21, 0.51] for single and recurrent IACI, respectively. Most PS matched analyses had >20,000 included patients (all joints combined), with covariates well balanced across IACI exposure status. PS matching confirmed a reduction in incidence of several pain medications associated with single IACI, e.g., lower incidence of partial opioids following IACI for any of hand, hip, knee or shoulder OA. Conclusion Our main findings suggest IACI use for hand or knee OA may reduce subsequent need for analgesics. Among knee OA patients, generally larger reductions were observed following recurrent than single IACI. In secondary analyses, single IACI for hand, hip, knee or shoulder OA was associated with lower subsequent use of partial opioids. Disclosure S. Hawley: None. A.

Formulation and Evaluation of Diclofenac Transdermal Gel

Diclofenac sodium gel is a widely used nonsteroidal anti-inflammatory drug (NSAID) formulation designed for topical application, primarily targeting local pain and inflammation. This wok aims to provide a comprehensive analysis of the anti-inflammatory activity of diclofenac sodium gel, focusing on its mechanism of action, efficacy, safety profile, and clinical applications. Several clinical studies have investigated the efficacy of diclofenac sodium gel in various inflammatory conditions, including osteoarthritis, rheumatoid arthritis, and soft tissue injuries. Results consistently demonstrate significant reductions in pain, swelling, and functional impairment, validating the gel's anti-inflammatory properties. The safety profile of diclofenac sodium gel is generally favorable, with local skin reactions being the most commonly reported adverse events. Systemic absorption is low, reducing the risk of gastrointestinal complications and other systemic side effects associated with oral NSAIDs. However, caution should be exercised in individuals with a history of hypersensitivity reactions or skin disorders.

Ultrasound guided injection with Collagen-based Medical Device: real-life evaluation of efficacy and safety in hip osteoarthritis.

Data regarding the treatment of hip osteoarthritis (OA) with collagen-based extracellular bio-scaffolds are lacking. We evaluated the treatment of hip OA with ultrasound guided intraarticular injections of Collagen-based Medical Device(CMD). Forty-four patients with Kellgren-Lawrence grade (KLG) I or II were selected, and 20/44randomly selected patients (CMD group), were treated with 2 weekly consecutive ultrasound guided intraarticular injections ofCMD (MD-HIP, Guna S.p.a. Milan, Italy). An additional 24/44 patients were treated with oral non-steroidal anti-inflammatorydrugs (NSAIDs) daily (NSAIDs group). Clinical assessment, X-rays and ultrasound evaluation were performed at baseline,and after 1 month in both groups, and after 3 months in the CMD group. Outcome measures were general pain VAS (0-10), thewhole WOMAC score, and the WOMAC specific subscores. CMD and NSAIDs group were homogenous for age,gender, VAS pain and WOMAC scores. The CMD group had significant improvement of the VAS pain (p<0.0001), globalWOMAC score (p<0.0001) and WOMAC function (p<0.0001) from baseline to the 1st month, with further improvementfrom the 1st to the 3rd month (p<0,001; p<0.01; p<0.03, respectively). Significant improvement in WOMAC pain (p<0.0001)and WOMAC stiffness (p<0.0001) was detected at 1st month, with no significant change at 3rd month. In the NSAIDs groupsignificant improvement in WOMAC function was detected after 1 month (p=0.021) only. No adverse events were recorded inthe CMD and NSAIDs group. The ultrasound guided intraarticular hip injections of CMD resulted in significantimprovement in VAS pain and WOMAC scores compared to treatment with oral NSAIDs.

Migraine treatment – updated recommendations 2024 –development of the Expert Group of the Headache Section ofthe Polish Neurological Society and the Polish Society for theStudy of Pain

Migraine is one of the most frequent disabling neurological conditions with a major impact on the patients qualityof life. Migraine treatment recommendations are provided based on a review of the literature from randomizedclinical trials and the consensus of a national expert panel. All available medical reference systems were screened for the range of past and present clinical studies on migraine with and without aura and on migraine-like syndromes.The results of these studies were presented in accordance with the recommendations of the Migraine Section ofthe Polish Neurological Society and the Polish Society for the Study of Pain. For the acute treatment of migraineattacks, oral non-steroidal antiinflammatory drug (NSAID), triptans and new class of drugs gepants and ditans arerecommended. The administration should follow the concept of stratified treatment. Before intake of NSAID andtriptans, oral metoclopramide is recommended. In very severe attacks, subcutaneous sumatriptan are drugs of firstchoice. Status migrainosus can be treated by cortoicosteroids, although this is not universally held to be helpful. Forthe prophylaxis of migraine, old and new drugs – betablockers flunarizine, valproic acid, and topiramate as well asmonoclonal anti CGRP antibodies, gepants and botulin toxin are drugs of first choice.

Arthroscopic debridement improves range of motion for heterotopic ossification after total knee replacement: a retrospective cohort study

The presence of heterotopic ossification (HO) after primary total knee replacement (TKR) is rare and associated with limited mobility and stiffness of the knee. This study aimed to identify if the arthroscopic debridement after TKR could decrease HO and improve the function and range of motion. Thirty HO patients after TKR were retrospectively separated into 2 cohorts. 15 patients of group A accepted the arthroscopic debridement, while 15 patients of group B only had non-operative treatment, mainly including oral nonsteroidal anti-inflammatory drugs (NSAIDs) and rehabilitative treatment. Visual analog scale (VAS) scores, knee society knee scores (KSS), range of motion (knee flexion and knee extension) were obtained before treatment and at 1 month, 3 months, and 6 months after treatment. Radiography of after-treatment was also evaluated to assess the changes in HO. There were 3 males and 27 females with a mean age of 67.4 ± 0.8 years in group A and 68.2 ± 1.3 in group B. The onset time of HO was 3–6 months. The maximum size of the ossification was < 2 cm in 23 knees, 2 cm < heterotopic bone < 5 cm in 6 knees and > 5 cm in 1 knee. The size of HO decreased gradually in all knees by X-ray film at the last follow-up. There were no significant differences in VAS scores after replacement between two groups (p > 0.05). The average range of motion preoperatively in group A was − 15.2–90.6°, which postoperatively increased to − 4.2–110.0°. Meanwhile, the KSS scores and average range of motion of the group A were better than those of the group B at each follow-up time after treatment. Arthroscopic debridement can decrease HO seen from postoperative X-rays, improve the function and range of motion, as well as the pain remission between two groups are comparable. Consequently, arthroscopic resection of HO after TKR is recommended as soon as there is aggravating joint stiffness.

Identifying Risk Factors for Cardiovascular Events Among Active-Duty Service Members and Veterans Prescribed Nonsteroidal Anti-Inflammatory Drugs (NSAIDs).

Oral NSAIDs are widely used analgesic medications for the treatment of musculoskeletal and inflammatory conditions. NSAIDs are associated with adverse effects that arise from COX enzyme inhibition including cardiovascular events. The combined role of patient and prescription factors associated with NSAID use on cardiovascular risk is not well characterized. The purpose of this study is to identify the risk factors with cardiovascular events among NSAID users. This study is a retrospective, nested case-control study, within the DAVINCI database, among active-duty service members and veterans with at least one NSAID pharmacy claim between fiscal year (FY) 2015-FY2020. Inclusion criteria individuals ≥18 years of age received a prescription NSAID for ≥7-day supply and a duration ≥1 month overall. Cases experienced nonfatal myocardial infarction, nonfatal stroke, or new onset heart failure. Ten controls were selected per case. Risk factors were identified through logistic regression modeling. The risk factors with strongest association to the primary outcome included age starting at 45 up to 75 and older, the first 90 days of NSAID exposure, cerebrovascular disease, cardiomyopathy, and history of myocardial infarction. Cox-selectivity and dose did not appear to be clinically significant in their association with cardiovascular events. The results of this study indicate that age, initial NSAID exposure, and comorbidities are more predictive than NSAID-specific factors such as COX-selectivity and dose. The results provide the framework for development of a risk score to improve prediction of NSAID-associated cardiovascular events.

Impact of lifestyle and clinical factors on the prognosis of tennis elbow

Tennis elbow (lateral epicondylitis) typically responds well to conservative treatment, and few patients require surgical intervention. This study aimed to investigate the influence of lifestyle and clinical factors on the prognosis of tennis elbow. This prospective, multicenter, nested case–control study included patients diagnosed with lateral epicondylitis after excluding other conditions. Patients who required surgery because of inadequate improvement after 6 months of conservative treatment were defined as the case group; the remaining patients constituted the control group. Propensity score matching was performed to eliminate baseline differences. Univariate and multivariate analyses were performed using logistic regression. This study included 265 patients (53 in the case group, 212 in the control group). Multivariate analysis revealed that smoking, alcohol consumption, and frequent physical exercise were independent risk factors for surgical intervention, whereas combined treatment with oral nonsteroidal anti-inflammatory drugs (NSAIDs) and local corticosteroid injections was a protective factor against surgery. Subgroup analysis showed that heavy drinkers had a 3.74-fold higher risk of requiring surgical treatment within 1 year than occasional drinkers. Smoking and alcohol consumption were associated with non-operative treatment failure in patients with lateral epicondylitis. Combining oral NSAIDs and corticosteroid injections is a favorable conservative treatment option.

Collaborative approach to paediatric chronic non-bacterial osteomyelitis of the mandible: Great Ormond Street Hospital case series

This paper outlines a 10-patient case series of chronic non-bacterial osteomyelitis (CNO) of the mandible at a tertiary paediatric hospital in the UK. Our findings highlight the homogeneous presenting signs and symptoms of an intermittently painful, swollen angle and ramus of the mandible. We present the typical laboratory investigative findings (normal inflammatory markers) and imaging appearances (sclerosis and periosteal oedema). Our paper outlines an investigation protocol, including recommendations for extraoral bone biopsies and systemic magnetic resonance imaging (MRI). We explain the importance of multidisciplinary care, with combined care by rheumatologists and infectious disease specialists. Finally we demonstrate the efficacy of our treatment algorithm for oral non-steroidal anti-inflammatory drugs (NSAIDs), and in those cases refractory to NSAIDS, intravenous pamidronate. This paper provides a useful addition to the literature by informing OMF surgeons of this rare condition and given the clinical equipoise in treatments, it can hopefully guide clinicians in an investigation pathway and management protocol.

Topical Chinese patent medicines for chronic musculoskeletal pain: systematic review and trial sequential analysis

PurposeChronic musculoskeletal pain (CMP) is defined as persistent or recurrent pain that occurs in the joints, musculo-soft tissue, spine or bones for more than three months and is not completely curable. Although topical Chinese patent medicine (CPM) is the most extensively utilized medication in Asia and is widely used for pain management, its efficacy remains controversial. This article presents a systematic review of clinical studies on the therapeutic properties of topical CPM for CMP patients to better inform clinical decision-making and provide additional and safer treatment options for patients with CMP.MethodWe performed a comprehensive search on PubMed, Cochrane Library, web of science and Chinese databases (CNKI and WanFang data) from 2010 to 2022. In all the studies, knee osteoarthritis, cervical spondylosis, low back pain, and periarthritis of shoulder met the International Pain Association definition of chronic musculoskeletal pain. We included only randomized controlled trials (RCTs) using topical CPM primarily for chronic musculoskeletal pain in adults. To determine the effect of topical CPM on clinical symptoms, we extracted the Visual Analog Scale (VAS, range 0–10) and the Western Ontario and McMaster Universities Arthritis Index pain scores (WOMAC pain, range 0–20), in which the lower the score, the better the results. We also accepted the comprehensive outcome criteria developed by the Chinese National Institute of Rheumatology as an endpoint (total effectiveness rate, range 0–100%, higher score = better outcome), which assesses the overall pain, physical function and wellness. Finally, trial sequential analysis of VAS pain score and total effectiveness rate was performed using TSA software.ResultsTwenty-six randomized controlled trials (n = 3180 participants) compared topical CPM with oral Nonsteroidal Anti-inflammatory Drugs (NSAIDs) (n = 15), topical NSAIDs (n = 9), physiotherapy (n = 5), exercise therapy (n = 4), and intra-articular Sodium hyaluronate injection (n = 2). Sixteen studies found that topical CPM was statistically significant in improving CMP pain (measured by VAS pain and Womac pain scores)(p < 0.05), and 12 studies found topical CPMs to be more clinically effective (assessed by ≥ 30% reduction in symptom severity) in treating patients with CMP (p < 0.05). Trial sequential analysis indicates that the current available evidence is robust, and further studies cannot reverse this result. In most of the studies, randomisation, allocation concealment and blinding were not sufficiently described, and no placebo-controlled trials were identified.ConclusionMost studies showed superior analgesic effects of topical CPM over various control treatments, suggesting that topical CPM may be effective for CMP and is an additional, safe and reasonable treatment option. These reported benefits should be validated in higher-quality RCTs.

Efficacy, Safety, and Acceptability of Manual Vacuum Aspiration with Para Cervical Block as a Management of Incomplete Abortion

Limited access to safe abortion is a leading cause of maternal mortality and morbidity in the developing world, overwhelming hospitals with a large number of women seeking treatment for complications of unsafe abortion. In many cases, more than half of all gynecological admissions are due to incomplete or septic abortions. The primary aims were to assess the efficacy and cost-effectiveness of the manual vacuum aspiration (MVA) procedure for managing incomplete abortion, considering completeness, procedure, duration, and hemorrhage. Additionally, safety aspects, such as complications (hemorrhage, perforation, and cervical injury), pain relief, patient satisfaction, and factors like reduced hospital stays and waiting times, were evaluated. This descriptive cross-sectional study was conducted at Dhaka Medical College and Hospital, focusing on women with incomplete abortions up to 12 weeks of gestation. It took place over six months from July to December 2013, with a purposive sample of 100 cases selected based on specific criteria to represent the study's objectives. Statistical analysis was done by using SPSS (version 16.0, SPSS Inc., Chicago, Illinois, USA). Out of 100 respondents, more than two-third of the patients (68%) were in 21-30 years age group. Half of the patients (50%) came from lower middle class family and most of them were housewives (80%). Majority (58%) of the patients had average gestational age 6-10 weeks. More than two-third (70%) of the patients had incomplete abortion, with 47% having attempted to terminate pregnancy. Abdominal pain was reported among 64% of patients, and the average bleeding period was 5-7 days for 62% of them. More than two-third (68%) of patients had no palpable uterus, and active bleeding was also found among two-third 66.0% of cases. Nearly one-third of the patients (32%) received injectable oxytocin and 13% received blood transfusion. Method of para-cervical block was applied for pain management in all patients (100%), while pethidine was used in only 3% of cases. Almost all of the patients 97%) were given sedatives (diazepam) and oral non-steroidal anti-inflammatory drugs (NSAIDs). Duration for the procedure was 10-15 minutes for 46% of patients, and excessive hemorrhage was found in 2% of cases. The average hospital stay ranged from 2-11 hours. Treatment cost in the majority of cases was only 75-150 Bangladeshi taka (BDT), which was statistically significant. The MVA with paracervical block was found to be efficient for treatment of incomplete abortions during the first trimester of pregnancy, with few complications. MVA procedure had less blood loss, less time consuming, safe and effective with shorter hospital stay. Bangladesh Med J. 2022 May; 51(2): 21-29

Knowledge About and the Use of Oral Nonsteroidal Anti-inflammatory Drugs Among Patients With Rheumatic Disorders in Saudi Arabia: A Cross-Sectional Study

Knowledge About and the Use of Oral Nonsteroidal Anti-inflammatory Drugs Among Patients With Rheumatic Disorders in Saudi Arabia: A Cross-Sectional Study

Abstract 17747: Gynecological Manifestations in a Patient With Arrhythmogenic Right Ventricular Cardiomyopathy: A Desmosomal Link?

Introduction: Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is inherited cardiomyopathy which is caused by desmosomal protein gene mutations, primarily in the desmoplakin (DSP), plakophilin-2 (PKP2), and desmoglein-2 (DSG2) genes. It is characterized pathologically by myocardial atrophy, fibrofatty replacement, and fibrosis, precipitating ventricular arrhythmias (VA). Desmosomal mutations have been linked to impaired follicular development and leiomyoma formation. However, there is little information about the association of their expression in myocardial with ovarian or uterine tissues. As incidences of ARVC/D in women increase, it is crucial to determine if women with the gynecological manifestations of these mutations are at a higher risk of developing ARCV/D. Case: We report a case of a 32-year-old female who presented with exercise-induced palpitations and syncopal episodes. She has a history of severe dysmenorrhea but has no medical conditions otherwise. On monitoring, she was found to have a high burden of ventricular premature complexes (VPCs). VAs were thought to have precipitated her syncopal episodes. She was started on antiarrhythmics. Echocardiogram demonstrated right ventricular dilatation and wall thinning. The patient later underwent genetic testing, which confirmed ARVC-associated mutations. Her dysmenorrhea was managed with combined oral contraceptives and nonsteroidal anti-inflammatory drugs. Pelvic ultrasound revealed leiomyomas, which were surgically removed. Discussion: This case supports the possible complex interplay between cardiovascular and gynecological conditions in patients with desmosomal mutations. Desmosomes are specialized protein complexes crucial in maintaining tissue's structural and mechanical stability. Mutations in desmosome genes disrupt the normal functioning of these protein complexes, leading to impaired cell-cell adhesion and increased vulnerability to tissue damage. The next step is to conduct studies to better understand the risk of developing cardiovascular disease in patients presenting with these gynecological conditions and vice versa to provide early monitoring and treatment.

Chronic shoulder injury related to vaccine administration following coronavirus disease 2019 vaccination: a case report

BackgroundShoulder injury related to vaccine administration, defined as shoulder pain and limited range of motion occurring after administration in the upper arm, has been previously reported. The symptom resolved completely after treatment with oral nonsteroidal anti-inflammatory drugs or an intraarticular steroid injection, however there have been few reports of long-term symptoms following coronavirus disease 2019 vaccination. This case report describes a healthy, middle-aged, healthcare worker who developed post-vaccination subacromial–subdeltoid bursitis that lasted for more than 6 months after Pfizer–BioNTech coronavirus disease 2019 vaccination.Case presentationA 55-year-old Japanese woman with no significant medical history was vaccinated in the standard site, with the needle direction perpendicular to the skin. Within a few hours after the second vaccination, severe shoulder pain and limited range of motion appeared. Although shoulder range of motion improved, her shoulder pain did not improved for several months, and she consulted an orthopedic doctor 5 months later. Radiographs of her left shoulder did not provide helpful diagnostic information. High intensity in the subacromial–subdeltoid space was seen on short TI inversion recovery of magnetic resonance imaging, showing subacromial–subdeltoid bursitis. She was diagnosed with a shoulder injury related to vaccine administration. The patient was started on an oral anti-inflammatory drug, and the left subacromial space was injected with 2.5 mg of betamethasone with 3 ml of 1% lidocaine without epinephrine every 2 weeks. One month after starting this treatment, since her shoulder pain had not improved, the oral anti-inflammatory drug was switched to tramadol hydrochloride acetaminophen. However, 3 months after switching medication, the shoulder pain continued, and she worked so as to have minimal impact on her shoulder.ConclusionA case of subacromial–subdeltoid bursitis following a second dose of the Pfizer–BioNTech coronavirus disease 2019 vaccine that lasted many months is reported. Injection technique is a modifiable risk factor, the adverse effects of which could potentially be mitigated with appropriate and relevant training of healthcare providers. To prevent this type of case, the appropriate landmark, needle length, and direction should be confirmed.

Research Progress on Pathogenesis and Treatment of Primary Dysmenorrhea

Primary dysmenorrhea is one of the common gynecological diseases of women of childbearing age, which can affect the work, study, and life of patients in severe cases. From the perspective of Western medicine, primary dysmenorrhea is caused by excessive secretion of prostaglandin and contraction of uterine smooth muscle, so the treatment focus of Western medicine is oral non-steroidal anti-inflammatory drugs or contraceptives, but its side effects cannot be ignored. From the perspective of Chinese medicine, primary dysmenorrhea is caused by qi-blood stagnation, so the focus of Chinese medication is dialectical treatment, which can improve qi-blood stagnation by acupuncture, decoction, moxibustion, etc., with fewer side effects and long-term clinical significance. The purpose of this paper is to analyze the relevant literature about the pathogenesis and treatment of primary dysmenorrhea in recent years, and to understand the research progress of primary dysmenorrhea in Western medicine and traditional Chinese medicine, so as to provide a reference for clinical treatment of primary dysmenorrhea.

The Single Intra-Articular Injection of Platelet-Rich Plasma vs. Non-Steroidal Anti-Inflammatory Drugs as Treatment Options for Canine Cruciate Ligament Rupture and Patellar Luxation.

Cranial cruciate ligament rupture (CCLR) and patellar luxation (PL) are common pathologies affecting canines. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used as a non-surgical treatment plan in these cases. Clinical usage of platelet-rich plasma (PRP) is an emerging area of interest in veterinary medicine. There is a lack of studies comparing those two different treatment methods in veterinary medicine. The main purpose of this study was to evaluate and compare the use of oral NSAIDs and single intra-articular injection of PRP on treatment outcomes in cases of canine CCLR and PL. Dogs diagnosed with CCRL (n = 12) and PL (n = 10) were subgrouped by the severity of pathologies and administered treatment: half of the CCRL and PL groups were orally administered NSAIDs and supplements for 14 days, and the other half received a single intra-articular PRP injection into affected stifle joint. We measured serum TNF-α levels and clinical outcomes (lameness scores, painfulness to manipulations, goniometry of stifle joint in flexion and extension, and muscle strength) before treatment, at day 14 and day 28 of treatment. The results of TNF-α concentration indicates a significant difference between groups of differently treated partial CCLR groups on d14 (p = 0.006). Results of group CCLR-P1 on d14 were decreased, while results of group CCLR-P2 on d14 were increased. When comparing TNF-α concentration between all CCLR cases treated with NSAIDs and treated with PRP, there was a significant difference between those groups on d14 (p = 0.001). The results of TNF-α concentration indicates a significant difference between groups of differently treated PL-III on d28 (p = 0.036). Results of group PL-III1 indicate growth of TNF-α concentration, while at the same d28, results of group PL-III2 indicate decreased levels of cytokine, comparing results between the subgroups at the same time point and within subgroups from baseline. Results indicate a significant difference in muscle strength between group CCLR-P1 and group CCLR-P2 on d28 (p = 0.007), indicating an increment in muscle strength in group CCLR-P1 up to d14 and its reduction up to d28, and muscle strength of group CCLR-P2 increasing up to d28. When comparing the muscle strength between all CCLR cases treated with NSAIDs and treated with PRP, there was a significant difference between those groups on d28 (p = 0.007). In conclusion, a single intra-articular injection of PRP has a superior effect on management of inflammatory processes, has better clinical outcomes, and longer duration of action than oral NSAIDs, in the treatment of canine CCRL or PL.

Effect of hydrocortisone ultrasonic phonophoresis in the treatment of knee osteoarthritis

Background: Knee Osteoarthritis (KOA) is a frequent type of degenerative joint disease, which results in a gradual loss of function, discomfort, and stiffness. KOA can be effectively treated with oral drugs such as corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs may raise the dangers of renal, gastrointestinal, and other systemic toxicities. Compared with oral NSAIDs, topical gels are an alternative therapeutic option with fewer side effects, with less therapeutic efficacy. Studies on ultrasound (US) as a therapeutic method go back a long time in KOA. US not only relieves symptoms but may also provide potential cartilage repair effects, and regulates inflammatory responses. Widely used as a physical enhancer of drug absorption is ultrasonic phonophoresis. By making the skin more permeable to topical pharmaceuticals, it improves the absorption of drugs used topically. (2) Material and method: A monocentric study was conducted in the Center of Physical Therapy and Rehabilitation - "Dunărea de Jos" University of Galați on 20 patients, diagnosed with bilateral and unilateral moderate KOA. The experimental group (EG) included 10 patients who received 10 sessions of PT (Physical Therapy), transcutaneous electrical nerve stimulation (TENS), and Ultrasound (US) phonophoresis therapy with hydrocortisone 10mg/g. The control group (CG) included 10 patients who received 10 sessions of TENS and US with neutral gel. (3) Results: All patients were clinically assessed with The "timed up and go test" (TUG), pain scale (VAS), and WOMAC. The t-test was used to calculate the statistical differences between the means of the EG and CG. (4) Conclusion: Hydrocortisone therapy combined with PT had a beneficial effect on pain and functional mobility in patients with KOA form EG. Furthermore, significantly greater improvement was observed among the intervention group with hydrocortisone.

Non-steroidal Anti-inflammatory Drugs and Osteopathic Manipulative Treatment for Pain Management in Patients With Osteoarthritis: A Literature Review.

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. Other non-pharmacologic therapies include weight loss, exercise, physical therapy (PT), and assistive devices. However, pharmacologic management may be added synergistically to control flares and maintain baseline activities of daily living. While oral non-steroidal anti-inflammatory drugs (NSAIDs) have been the mainstay of treatment for pain and inflammation associated with OA, they have a non-selective inhibitory action that often results in negative side effects when used chronically. The possibility of minimizing these complications through alternate treatments such as topical NSAIDs provides an opportunity for patients to receive adequate pain relief from OA without suffering unnecessary consequences. This literature review seeks to assess the state of research regarding topical NSAIDs and OMT as alternatives to the current gold-standard treatment of OA. The significant inclusion criteria consisted of articles that described the effects of OMT on OA or the use of topical NSAIDs such as Voltaren on OA. Due to the limited articles found, a qualitative analysis was performed, and the salient conclusions are outlined. Alternative pharmacological and non-pharmacological treatments, such as topical diclofenac gel and OMT, have shown promising results in the treatment of pain in OA. It is seen that a majority of patients achieve pain management using NSAIDs, acetaminophen, or topical analgesics. Both diclofenac sodium and OMT have individually been shown to be effective treatments of OA when compared to the use of oral NSAIDs. A holistic treatment approach that utilizes both topical diclofenac sodium and OMT may provide OA patients with an effective option to reduce their moderate to severe chronic pain with limited side effects. Further, high-quality randomized controlled trials are needed to identify whether synergistic effects occur when combining diclofenac sodium gel and OMT for pain relief in patients with OA.

β-Caryophyllene-Loaded Microemulsion-Based Topical Hydrogel: A Promising Carrier to Enhance the Analgesic and Anti-Inflammatory Outcomes.

Musculoskeletal pain and inflammation can vary from localised pain like pain in the shoulders and neck to widespread pain like fibromyalgia, and as per estimates, around 90% of humans have experienced such pain. Oral non-steroidal anti-inflammatory drugs (NSAIDs) are frequently prescribed for such conditions but are associated with concerns like gastric irritation and bleeding. In the present study, a microemulsion-based gel comprising β-caryophyllene, isopropyl myristate, Tween 80, and normal saline was prepared as a topical option for managing topical pain and inflammation. The globules of the microemulsion were below 100 nm with a zetapotential of around -10 mV. The drug entrapment was >87% with a drug loading of >23%. The permeation studies established better skin permeation (20.11 ± 0.96 μg cm-2 h-1) and retention of the drug (4.96 ± 0.02%) from the developed system vis-à-vis the conventional product (9.73 ± 0.35 μg cm-2 h-1; 1.03 ± 0.01%). The dermatokinetic studies established the better pharmacokinetic profile of the bioactive in the epidermis and dermis layers of the skin. The anti-inflammatory potential in carrageenan-induced rat paw oedema was more pronounced than the conventional product (~91% vis-à-vis ~77%), indicating a better pharmacodynamic outcome from the developed system. The nanotechnology-based natural bioactive product with improved efficacy and drug loading can provide a better alternative for the management of musculoskeletal pain.
