A multi-professional survey of UK practice in the use of intra-articular corticosteroid injection for symptomatic first metatarsophalangeal joint osteoarthritis.

BACKGROUND: The first metatarsophalangeal joint is the most common site of osteoarthritis (OA) in the foot and ankle. Intra-articular corticosteroid injections are widely used for this condition, but little is known about their use in practice. This study explored current practice within the UK National Health Service (NHS) relating to the administration of intra-articular corticosteroids for people with painful first metatarsophalangeal joint (MTPJ) OA. METHODS: A cross-sectional survey using Qualtrics online survey platform (Qualtrics, Provo, UT, USA), distributed through professional bodies, special interest groups, and social media. RESULTS: One hundred forty-four healthcare professionals responded, including podiatrists (53/144; 39%), orthopaedic surgeons (28/144; 19%), podiatric surgeons (26/144; 17%) and physiotherapists (24/144; 16%). Half of respondents administered up to 25 corticosteroid injections per year (67/136; 49%) but some administered more than fifty (21/136; 15%). Injections were administered across the healthcare system but were most common in hospital settings (64/136; 44%) followed by community (38/136; 26%), with less delivered in primary care (11/136; 8%). Half of respondents routinely used image-guidance, either ultrasound or x-ray/fluoroscopy (65/136; 48%) although over one third used none (52/136; 38%). Imaging guidance was more common amongst medical professionals (21/31; 68%) compared to non-medical health professionals (45/105; 43%). Overall, methylprednisolone acetate was the most common corticosteroid used. Medical professionals mostly injected methylprednisolone acetate (n = 15/27; 56%) or triamcinolone acetonide (n = 11/27; 41%), whereas premixed methylprednisolone acetate with lidocaine hydrochloride was the most common preparation used by non-medical health professionals (41/85; 48%). When injecting non premixed steroid, lidocaine hydrochloride (15/35; 43%) was the most common choice of local anaesthetic for non-medical health professionals but medical professionals showed more variation between lidocaine hydrochloride (8/23; 35%) levobupivacaine hydrochloride (9/23; 39%) and bupivacaine hydrochloride (5/23; 22%). CONCLUSIONS: Multiple professional groups regularly administer intra-articular corticosteroids for symptomatic first MTPJ OA across a range of NHS healthcare settings. Overall, methylprednisolone acetate was the most commonly administered steroid and lidocaine hydrochloride the most common local anaesthetic. There was large variation in the use of imaging guidance, type and dose of steroid, local anaesthetic, and clinical pathways used in the intra-articular injection of corticosteroids for people with first MTPJ OA.

Comparison of the Particulate Steroids, Betamethasone and Methylprednisolone, in Caudal Steroid Injection Under Ultrasound Guidance.

BACKGROUND: Pain relief in lumbar disc hernias is a challenging condition. This study retrospectively compared particulate steroids, methylprednisolone acetate (mid-term effective), against betamethasone acetate (long-term effective) on ultrasound-guided caudal epidural injection for lumbar disc herniation. METHODS: A total of 40 patients with L4-5 and/or L5-S1 disc herniation were treated with ultrasound-guided caudal epidural injection between September 2021 and June 2022. Nineteen patients who were given methylprednisolone acetate (group A) as a steroid and a total of 21 patients who were used betamethasone acetate (Group B) were retrospectively collected, and their pain levels and functional improvement were compared retrospectively before, immediately after, and 3 weeks after the injection in terms of the visual analog scale (VAS) and Oswestry Disability Index (ODI) as the efficacy value. RESULTS: There was no statistically significant difference between the groups regarding age, gender, and body mass index (P > 0.05). In group A, preop VAS was 8.84 ± 0.76, immediate postop period 3.10 ± 1.37, and postop third week was 4.73 ± 2.32. In group B, the preop VAS was 8.76 ± 0.76, the postop early period was 3.14 ± 1.27, and the postop third week was 3.12 ± 1.30. In group A preop ODI was 49.84 ± 9.11 and postop third week was 22.84 ± 6.44. In group B, the preop ODI was 46.71 ± 16.15 and postop third week was 30.80 ± 17.65. Significant changes were observed in the reduction of VAS values after the procedure in both groups during the early postoperative period and the third week (P value < 0.05). However, a significant difference was not found between the changes in VAS values between the groups (P value > 0.005). Similarly, significant changes were observed in the decrease of ODI values after the procedure in both groups during the early postoperative period and the third week (P value < 0.05). However, no significant difference was observed in the ODI scores between the two groups. CONCLUSIONS: No significant difference was observed between betamethasone and methylprednisolone. Both steroid groups showed a substantial improvement in the preoperative pain scores of the patients.

Treatment of Advanced Coats' Disease With Combination Therapy of Laser Photocoagulation, Intravitreal Ranibizumab, and Sub-Tenon Methylprednisolone Acetate.

PURPOSE: To investigate the efficacy of combination therapy with laser photocoagulation, intravitreal ranibizumab, and sub-Tenon methylprednisolone acetate in patients presenting with advanced Coats' disease. METHODS: This was a retrospective analysis of 16 patients who underwent laser photocoagulation combined with intravitreal ranibizumab and sub-Tenon methylprednisolone acetate between 2008 and 2017. The primary outcome was anatomic success and the secondary outcomes were globe preservation and final visual acuity. RESULTS: The average age at surgery was 5.12 ± 2.7 years (range: 3 to 10 years). The mean follow-up time was 45.43 ± 29.01 months (range: 12 to 108 months). Of the 16 patients (16 eyes) reviewed, 6 patients had stage 3A and 10 patients had stage 3B Coats' disease. The mean number of applications was 10 (range: 4 to 18). Globe preservation was achieved in all patients. Final visual acuity outcomes were satisfactory: 20/20 to 20/50 in 2 patients, 20/60 to 20/100 in 1 patient, and 20/200 or worse in 13 patients. CONCLUSIONS: Intravitreal ranibizumab used in combination with laser photocoagulation and sub-Tenon methylprednisolone acetate could be an effective treatment option for patients with advanced Coats' disease. The combined therapy achieved anatomical success, globe preservation, and reasonable visual acuity outcomes. [J Pediatr Ophthalmol Strabismus. 2022;59(3):187-191.].

Efficacy and safety of intraarticular corticosteroid injections in adolescents with juvenile idiopathic arthritis in the temporomandibular joint: a Norwegian 2-year prospective multicenter pilot study.

BACKGROUND: Intraarticular corticosteroids (IACs) have been used to treat temporomandibular joint (TMJ) arthritis. However, prospective clinical studies with magnetic resonance imaging (MRI) scoring are lacking. The aim of this study was to examine efficacy and safety of a single IAC in the TMJ in adolescents with juvenile idiopathic arthritis (JIA) in a clinical setting. METHODS: In this Norwegian prospective multicenter pilot study 15 patients with JIA (mostly persistent oligoarthritis or RF negative polyarthritis categories) and a clinically and MRI-verified diagnosis of TMJ arthritis were treated with IACs and followed for 2 years. Demographics, systemic medication, general disease activity and outcome measures were recorded including a pain-index score and maximal incisal opening (MIO). Inflammation and bone damage scores were assessed, using two recently published MRI scoring systems with masked radiological evaluation. RESULTS: Among the 15 patients, 13 received a single IAC (5 bilateral), and 2 repeated IACs once unilaterally. Thus, the total number of IACs was 22. Median age was 15 years and the majority had an age not thought of as critical regarding mandibular growth retardation due to steroid injection. During the 2-year observation period systemic medication with disease modifying antirheumatic drugs (DMARDs) including biologics was initiated or adjusted in 10/15 (67%) patients. At the 2-months study visit after injection we observed a minimal improvement in MIO from median 44 (1st, 3rd quartiles; 36, 48) mm to 45 (43, 47) mm, p = 0.045 and decreased MRI mean additive inflammatory score from 4.4 ± 1.8 standard deviations (SD) to 3.4 ± 2.0, p = 0.040. From baseline to the 2-months follow-up pain improved in 6/11 patients but pain scores were not significantly improved. MRI-assessed damage increased in two patients with repeated IACs, and decreased in 3 patients but most of the patients were stable over the 2-year follow-up. Intra-rater repeatability of the MRI scoring system domains varied from poor to excellent. CONCLUSIONS: In this pilot study of predominately single IACs to the TMJ in combination with systemic treatment we observed improvement in MRI-assessed inflammation, mostly stable condylar bone conditions and minimal clinical improvement in adolescents with JIA and TMJ arthritis. No severe side effects were seen.

Oral Gabapentinoids and Nerve Blocks for the Treatment of Chronic Ocular Pain.

PURPOSE: There is a recognition that nerve dysfunction can contribute to chronic ocular pain in some individuals. However, limited data are available on how to treat individuals with a presumed neuropathic component to their ocular pain. As such, the purpose of this study was to examine the efficacy of our treatment approaches to this entity. METHODS: A retrospective review of treatments and outcomes in individuals with chronic ocular pain that failed traditional therapies. RESULTS: We started eight patients on an oral gabapentinoid (gabapentin and/or pregabalin) as part of their pain regimen (mean age 46 years, 50% women). Two individuals reported complete ocular pain relief with a gabapentinoid, in conjunction with their topical and oral medication regimen. Three individuals noted significant improvements, one slight improvement, and two others no improvement in ocular pain with gabapentin or pregabalin. We performed periocular nerve blocks (4 mL of 0.5% bupivacaine mixed with 1 mL of 80 mg/mL methylprednisolone acetate) targeting the periocular nerves (supraorbital, supratrochlear, infratrochlear, and infraorbital) in 11 individuals (mean age 54 years, 36% women), 10 of whom had previously used a gabapentinoid without ocular pain improvement. Seven individuals experienced pain relief after nerve blocks that lasted from hours to months and four failed to benefit. Five of the individuals who experienced pain relief underwent repeat nerve blocks, weeks to months later. CONCLUSIONS: Approaches used to treat chronic pain outside the eye can be applied to ocular pain that is not responsive to traditional therapies.

Lumbosacral Radiculopathy: Inciting Events and Their Association with Epidural Steroid Injection Outcomes.

OBJECTIVE: Low back pain is the leading cause of worldwide disability, with lumbosacral radiculopathy accounting for over one-third of these cases. There are limited data on the relationship between etiologies and lumbosacral radiculopathy, and it is unknown whether specific causes predict treatment outcomes. DESIGN, SETTING, AND SUBJECTS: This study explores patient-reported etiologies for lumbosacral radiculopathy in a chronic pain clinic between January 2007 and December 2015 and examines whether these causes affected epidural steroid injection outcomes. METHODS: We reviewed the medical records of 1,242 patients with lumbosacral radiculopathy who received epidural steroid injections. The recording of an inciting event was done contemporaneously based on note templates. A positive outcome following an epidural steroid injection was defined as ≥30% pain relief sustained for six or more weeks without additional intervention. Factors associated with epidural steroid injection outcome were analyzed by multivariable logistic regression. RESULTS: Fifty point seven percent reported an inciting event, and 59.9% of patients experienced a positive epidural steroid injection outcome. The most commonly reported causes were falls (13.1%), motor vehicle collisions (10.7%), and lifting (7.8%). Individuals with a herniated disc (56.3%) were more likely to report a precipitating cause than those with stenosis (44.7%) or degenerative discs (47.8%, P = 0.012). An inciting event did not predict treatment outcome. Factors associated with negative treatment outcome included opioid consumption (odds ratio [OR] = 0.61, 95% confidence interval [CI] = 0.39-0.95, P = 0.027), secondary gain (OR = 0.69, 95% CI = 0.50-0.96, P = 0.030), and baseline pain score (OR = 0.90, 95% CI = 0.84-0.97, P = 0.006). The number of levels injected was associated with a positive outcome (OR = 2.72, 95% CI = 1.28-6.47, P = 0.008). CONCLUSIONS: Reported inciting events are common in patients with lumbosacral radiculopathy but are not associated with outcome following epidural steroid injection, and their occurrence is not always consistent with the purported mechanism of injury.

Intra-articular Corticosteroids for Knee Pain-What Have We Learned from the Equine Athlete and Current Best Practice.

The use of intra-articular corticosteroids for traumatic arthritis and osteoarthritis (OA) is common in the horse. The beneficial and deleterious effects of the principal corticosteroids used betamethasone esters (Celestone [Soluspan], methylprednisolone acetate [Depo Medrol], and triamcinolone acetonide [TA] [Vetalog or Kenalog]) have been defined for the horse. While TA has both disease-modifying as well as symptom-modifying effects, methyl prednisolone acetate has deleterious effects on the articular cartilage. Studies in traumatically injured joints show the same rationale (suppression of deleterious mediators associated with inflammation) and positive results from the use of TA in both equine and human patients. Studies in the experimental equine OA model allow for more in-depth knowledge of disease-modifying effects. Recent insights allow us to understand posttraumatic OA as an early consequence of joint injury that may require a more aggressive and proactive treatment approach than commonly applied to date.

Retrospective Study on the Effects of Long-Term Use of Methylprednisolone Acetate on the Blood Work of 25 Cats.

Twenty-five cats at a private animal sanctuary received multiple nonimmunosuppressive doses of parenteral methylprednisolone acetate for at least 3 yr. Complete blood count, chemistry, and T4 results from these cats were examined to look for statistically significant changes. Results found significant changes in triglycerides, amylase, and monocytes. However, these changes remained within the reference interval. All other values showed no significant changes. These results suggest that after 3 yr of chronic parenteral administration of nonimmunosuppressive doses of methylprednisolone acetate, the complete blood count, chemistry, and T4 values in 25 cats were not significantly affected and did not result in abnormal laboratory values.

Juvenile idiopathic arthritis flare due to rice bodies in the knee of a 10-year-old girl.

A 10-year-old girl with juvenile idiopathic arthritis in remission presented with a flare of her arthritis. All her joints responded to treatment except the right knee, despite the use of disease-modifying antirheumatic drugs, non-steroidal anti-inflammatory medication and high-dose cortisone. A magnetic resonance imaging scan showed a knee densely packed with rice bodies. After surgical removal of the rice bodies the inflammation settled once again, and the patient remains well on her usual medication.

Ultrasound Diagnosis of Osteophytic Impingement of the Popliteus Tendon After Total Knee Replacement.

We report our experience with 6 patients who had total knee replacements with lateral-sided knee pain, referred for ultrasound (US) assessment and US-guided injection. All cases showed an osteophyte within the popliteus sulcus of the lateral femoral condyle impinging on the adjacent tendon. Five of 6 patients reported improvement of symptoms immediately after US-guided injection of an anesthetic and a steroid. Ultrasound has a unique role in the imaging of knee replacements because of its real-time capabilities and absence of artifacts at the popliteus tendon origin.
