PURPOSE: To investigate the cost-effectiveness of prophylactic treatments against cystoid macular edema (CME) after cataract surgery in diabetic patients.SETTING: Seven ophthalmology clinics in the Netherlands and Belgium.DESIGN: Prospective trial-based cost-effectiveness analysis using data from a European multicenter randomized clinical trial.METHODS: Diabetic patients (n=163) undergoing uncomplicated cataract surgery were randomized to perioperative subconjunctival triamcinolone acetonide (n=36), perioperative intravitreal bevacizumab (n=36), combination treatment (n=45), or no additional treatment (control group, n=46). The cost analysis was performed from a healthcare perspective within a 12-week postoperative time horizon. The main effectiveness outcome was quality-adjusted life years (QALYs). The main cost-effectiveness outcome was the incremental cost-effectiveness ratio (ICER; cost per QALY).RESULTS: Mean total healthcare costs and QALYs were: Triamcinolone € 1827 (US$ 2295) / 0.166; Bevacizumab € 2050 (US$ 2575) / 0.144; Combination € 2027 (US$ 2546) / 0.166; Control € 2041 (US$ 2564) / 0.156. Bevacizumab and control treatment were most costly and least effective. The ICER was € 321,984 (US$ 404,503) per QALY for the combination group compared to the triamcinolone group. Assuming the willingness-to-pay is € 20,000 (US$ 25,126) per QALY, the cost-effectiveness probability was 70% and 23% in the triamcinolone and combination groups, respectively. No patient that received triamcinolone developed clinically significant macular edema (CSME). A secondary cost-effectiveness analysis based on this outcome showed a clear preference for triamcinolone.CONCLUSIONS: In diabetic patients, subconjunctival triamcinolone was effective in preventing CSME after cataract surgery. The cost-effectiveness analysis showed triamcinolone is also cost-effective.

PURPOSE To assess the relationship between best corrected visual acuity (BCVA) and central subfield optical coherence tomography (OCT) features in noninfectious uveitis (NIU)-related macular edema (ME). DESIGN Clinical cohort study from post hoc analysis of two phase 3 clinical trials' data. METHODS Correlation and longitudinal treatment analyses were performed. Of 198 patients with NIU, 134 received suprachoroidally administered CLS-TA (Clearside Biomedical, Inc. proprietary formulation of a triamcinolone acetonide injectable suspension) and 64 received sham, with 12.9% and 72% respectively receiving rescue therapy. RESULTS At baseline, mean BCVA progressively worsened with each ordinal drop in ellipsoid zone (EZ) integrity. Eyes with normal baseline EZ experienced greater 24-week change in BCVA compared to eyes with some degree of baseline EZ disruption (11.9 vs 9.4 letters, P=0.006). In contrast, eyes without central subfield cystoid spaces and/or central subfield SRF at baseline showed less improvement (5.5 letters or 9.5 letters, respectively) at 24 weeks, compared to those eyes with such OCT findings (13.7 letters, P = 0.012 or 17.2 letter, P

We aimed at determining the predictors of osteonecrosis (ON) in a longitudinal lupus cohort.Data were reviewed from the initiation of the cohort in 1987 until October 2019. In total, 2,428 patients were included in the analysis based on 224,295 person-months of follow-up. We used pooled logistic regression to assess the relationship between risk factors and rates of ON events. After identifying a set of variables related to ON incidence, we fit a final multivariable model to identify the most important risk factors for incident ON.In 18,691 person-years of follow-up after cohort entry, 122 incident ON events were observed (rate = 6.5/1,000 person-years). In the multivariable analysis, African American patients were at twice the risk for ON compared to White patients. Male patients and smokers had an increased risk for ON of ~80% and 50% compared to female patients and nonsmokers, respectively. For every 10-year increase in the age at diagnosis, there was a 20% reduced risk for ON. Patients diagnosed after the 1990s had a 50% reduced risk of ON compared to those diagnosed before the 1990s. A highest daily dosage of prednisone of 40 mg or higher, even when administered for a month or less, significantly increased the risk of ON. Use of pulse methylprednisolone or intramuscular triamcinolone was not associated with an increased risk of ON.African American patients with systemic lupus erythematosus are at double the risk of experiencing ON compared to White patients. Oral prednisone at 20-39 mg for more than 1 month, or 40 mg daily for even 1 month, at any point in the disease course, remained the most important glucocorticoid predictor of ON.

In reaction to skin injury in genetically predisposed persons, the keloid is formed and marked by benignant overgrowth of dermic collagen. Intralesional triamcinolone was used in the treatment of keloids with varying results.Intralesional triamcinolone is a gold standard in treating the keloids in comparison with its effectiveness versus intralesional 5-fluorouracil intralesional verapamil and intralesional platelet-rich plasma.Several 160 cases were categorized into four groups of each group-containing 40 cases. Group-A (control) treated with intralesional triamcinolone and Group-B intralesional verapamil, Group-C intralesional 5-fluorouracil, and Group-D intralesional platelet-rich plasma. Patients were assessed for clinical response based on a decrease in the patient and observer scar assessment scale (POSAS) at baseline and the end of treatment.The mean base-line POSAS score was 91 ± 10.98 SD check-in Group-A, 90 ± 10.85 in Group-B, 89 ± 10.06 in Group-C, and 92 ± 10.84 in Group-D. POSAS score after 24 weeks 36 ± 12.74 in Group-A, 29 ± 10.91 in Group-B, 39 ± 13.74 in Group-C, 36 ± 12.74 in Group-D. Statistically, a significant difference was observed between groups.Intralesional verapamil reported to be the most effective therapy and platelet-rich plasma was effective as intralesional triamcinolone acetonide with no serious side effects and 5-fluorouracil was less effective in treating the keloids.

Abstract: Objectives: Pterygium is a fibrovascular external ocular mass that grows from the conjunctiva into the cornea. The effect of subconjunctival injection of triamcinolone and bevacizumab has been inadequately investigated worldwide. This study aims to analyse the expression of IL-1 after the injection of triamcinolone and bevacizumab subconjunctiva. Methods: All patients are randomized into three groups: the triamcinolone, bevacizumab group, and placebo groups, with 5 patients in each in group. All subjects are injected subconjunctivally one week before surgery, and then surgery is performed with the autograft technique. The main outcome measures include changes in the IL-1 mRNA expression between the triamcinolone, bevacizumab, and placebo groups. Results: All samples are completed after one month of follow-up. The changes in blood levels of mRNA IL-1 expression are as follows: 4.81 ± 0.52 in the bevacizumab group, 3.40 ± 2.63 in the triamcinolone group, and 1.08 ± 1.48 in the placebo group (p = 0.04). In the comparison between groups, there is a significant effect between the bevacizumab and placebo groups, 3.73 ± 1.12 (p = 0.00), with no significant effect in the triamcinolone group, 1.40 ± 1.12 (p = 0.06). Conclusion: The subconjunctival injection of bevacizumab and triamcinolone before surgery is effective in suppressing inflammation in pterygium.

Purpose To review the evidence on the safety and efficacy of current anti-vascular endothelial growth factor (VEGF) and intravitreal corticosteroid pharmacotherapies for the treatment of diabetic macular edema (DME). Methods Literature searches were last conducted on May 13, 2020, in the PubMed database with no date restrictions and limited to articles published in English. The combined searches yielded 230 citations, of which 108 were reviewed in full text. Of these, 31 were deemed appropriate for inclusion in this assessment and were assigned a level of evidence rating by the panel methodologist. Results Only the 21 articles with level I evidence were included in this assessment. Seventeen articles provided level I evidence for 1 or more anti-VEGF pharmacotherapies, including ranibizumab (14), aflibercept (5), and bevacizumab (2) alone or in combination with other treatments for DME. Level I evidence was identified in 7 articles on intravitreal corticosteroid therapy for treatment of DME: triamcinolone (1), dexamethasone (4), and fluocinolone acetonide (2). Conclusions Review of the available literature indicates that intravitreal injections of anti-VEGF agents and corticosteroids are efficacious treatments for DME. Elevated intraocular pressure and cataract progression are important potential complications of corticosteroid therapy. Further evidence is required to assess the comparative efficacy of these therapies. Given the limited high-quality comparative efficacy data, choice of therapy must be individualized for each patient and broad therapeutic access for patients is critical to maximize outcomes.

Keloid scarring is one of the most common types of pathological scarring. Keloid scars that fail to heal can affect a person's physical and psychological function by causing pain, pruritus, contractures, and cosmetic disfigurement. Silicone gel sheeting (SGS) is made from medical-grade silicone reinforced with a silicone membrane backing and is one of the most commonly used treatments for keloid scars. However, there is no up-to-date systematic review assessing the effectiveness of SGS for keloid scars. A clear and rigorous review of current evidence is required to guide clinicians, healthcare managers and people with keloid scarring.To assess the effectiveness of silicone gel sheeting for the treatment of keloid scars compared with standard care or other therapies.We used standard, extensive Cochrane search methods. The latest search date was December 2021.We included randomised controlled trials (RCTs) that recruited people with any keloid scars and assessed the effectiveness of SGS.Two review authors independently performed study selection, risk of bias assessment, data extraction and GRADE assessment of the certainty of evidence. We resolved initial disagreements by discussion, or by consulting a third review author when necessary.Two studies met the inclusion criteria. Study sample sizes were 16 and 20 participants. The trials were clinically heterogeneous with differences in causes for scarring (e.g. surgery, infected wounds, and trauma), site (e.g. chest and back), and ages of scars. The duration of follow-up was three and four and a half months. The included studies reported three comparisons; SGS compared with no treatment, SGS compared with non-silicone gel sheeting (a dressing similar to SGS but which does not contain silicone), and SGS compared with intralesional injections of triamcinolone acetonide. One trial had a split-body design and one trial had an unclear design (resulting in a mix of paired and clustered data). The included studies reported limited outcome data for the primary review outcome of scar severity measured by health professionals and no data were reported for severity of scar measured by patients or adverse events. For secondary outcomes some data on pain were reported, but health-related quality of life and cost-effectiveness were not reported. Both trials had suboptimal outcome reporting, thus many domains in the risk of bias were assessed as unclear. All evidence was rated as being very low-certainty, mainly due to risk of bias, indirectness, and imprecision. SGS compared with no treatment Two studies with 33 participants (76 scars) reported the severity of scar assessed by health professionals, and we are uncertain about the effect of SGS on scar severity compared with no treatment (very low-certainty evidence, downgraded once for risk of bias, once for inconsistency, once for indirectness, and once for imprecision). We are uncertain about the effect of SGS on pain compared with no treatment (21 participants with 40 scars; very low-certainty evidence, downgraded once for risk of bias, once for inconsistency, once for indirectness, and once for imprecision). No data were reported for other outcomes including scar severity assessed by patients, adverse events, adherence to treatment, health-related quality of life and cost-effectiveness. SGS compared with non-SGS One study with 16 participants (25 scars) was included in this comparison. We are uncertain about the effect of SGS on scar severity assessed by health professionals compared with non-SGS (very low-certainty evidence, downgraded once for risk of bias, once for indirectness, and once for imprecision). We are also uncertain about the effect of SGS on pain compared with non-SGS (very low-certainty evidence, downgraded once for risk of bias, once for indirectness, and once for imprecision). No data were reported for other outcomes including scar severity assessed by patients, adverse events, adherence to treatment, health-related quality of life and cost-effectiveness. SGS compared with intralesional injections of triamcinolone acetonide One study with 17 participants (51 scars) reported scar severity assessed by health professionals, and we are uncertain about the effect of SGS on scar severity compared with intralesional injections of triamcinolone acetonide (very low-certainty evidence, downgraded once for risk of bias, once for indirectness, and once for imprecision). This study also reported pain assessed by health professionals among 5 participants (15 scars) and we are uncertain about the effect of SGS on pain compared with intralesional injections of triamcinolone acetonide (very low-certainty evidence, downgraded once for risk of bias, once for indirectness, and twice for imprecision). No data were reported for other outcomes including scar severity assessed by patients, adverse events, adherence to treatment, health-related quality of life and cost-effectiveness.There is currently a lack of RCT evidence about the clinical effectiveness of SGS in the treatment of keloid scars. From the two studies identified, there is insufficient evidence to demonstrate whether the use of SGS compared with no treatment, non-SGS, or intralesional injections of triamcinolone acetonide makes any difference in the treatment of keloid scars. Evidence from the included studies is of very low certainty, mainly driven by the risk of bias, indirectness, and imprecision due to small sample size. Further well-designed studies that have good reporting methodologies and address important clinical, quality of life and economic outcomes are required to reduce uncertainty around decision-making in the use of SGS to treat keloid scars.

Background This post hoc analysis compared the efficacy and safety of CLS-TA to other commonly available treatments for noninfectious uveitis (NIU). Methods Results from the PEACHTREE study were compared between subjects randomized to CLS-TA not requiring rescue therapy and those subjects randomized to control and subsequently requiring rescue therapy. Endpoints included best corrected visual acuity (BCVA), central subfield thickness (CST), treatment emergent adverse events (TEAEs), and intraocular pressure (IOP) related safety findings. Results In this analysis, there were 83 unrescued CLS-TA subjects and 46 rescued control subjects. At Week 24, 51.9% of the unrescued CLS-TA subjects gained ≥15 letters in BCVA, compared to 37.0% of the rescued control subjects (P = 0.115). Unrescued CLS-TA subjects showed a mean gain of 15.7 versus 10.9 letters in rescued control subjects (P = 0.080). A significantly greater mean reduction in CST was observed for unrescued CLS-TA subjects versus rescued control subjects (174.0 and 148.5 μm; P = 0.040). Of unrescued CLS-TA subjects, 4.9% experienced IOP elevations ≥ 30 mm Hg at any visit versus 10.9% of rescued control subjects. Further, use of IOP-lowering medications appeared lower in unrescued CLS-TA subjects versus rescued control subjects (7.2% versus 13.0%). There were no IOP-related surgical interventions in either group. Conclusion CLS-TA subjects experienced significantly greater reduction in CST and tended towards greater improvement in BCVA, compared with rescued control subjects. Suprachoroidally administered CLS-TA showed a lower incidence of IOP-related safety findings. This article is protected by copyright. All rights reserved.

To evaluate the effects of diabetes and corticosteroid injected in the joints on the shoulder motion, gait, and joint capsular properties in a rat stiffness model.A total of 27 rats were randomly distributed into 3 groups-nondiabetes group (group A), diabetes group (group B), and diabetes plus steroid injection group (group C). The diabetes model was developed by inducing hyperglycemia with a submaximal dose of streptozotocin and the stiffness model by completely immobilizing the right shoulder of each animal in all groups with sutures passed between the scapula and humeral shaft. The left shoulder was used as an untreated control in all groups. Three weeks after immobilization, the sutures were removed in all groups, and a single dose of triamcinolone acetonide (0.5 mg/kg) was injected into the glenohumeral joint in group C. After 3 weeks of free activity, range of motion (ROM) evaluation, gait analysis by stride length, and capsular area measurement were performed in all rats.Hyperglycemia was successfully induced with a mean blood glucose level of 448.9±55.9 mg/dL in group B and 431.6±17.8 mg/dL in group C, which were significantly higher than 136.5±13.4 mg/dL in group A (P.001). A significantly smaller ROM and stride length were found in the right (stiffness-induced) shoulder than that in the left (control) shoulder only in group B, and significantly larger capsular area in the right shoulder than that in the left shoulder in groups A and B (all P.05). However, in group C, there were no differences between the right and left shoulders in all measurements (all P.05). In case of the right shoulders in each group, group C showed significantly larger ROM (68° ± 11° vs. 42° ± 7°) and smaller capsular area (3934.4 ± 537.1 pixels vs. 7402.3 ± 1840.3 pixels) than group B (all P.0167).The diabetic model had a detrimental effect on the development of stiffness by thickening the joint capsule, and an intra-articular steroid injection resolved the thickened joint capsule and restored shoulder motion.

Keloids are disfiguring pathological scars that could cause pain and pruritus. The conventional treatments, such as bolus injection of drugs or surgery, are invasive and require a personal visit to clinic. Microneedle (MN) technology has great potential to offer a self-administered and minimally invasive treatment of keloids. However, drugs delivered using MNs suffer from limited penetration in keloid tissue. This study demonstrates enhanced drug penetration in human keloid scar tissue by combining MN and sonophoresis.

Oral lichen planus (OLP) is a chronic non-infectious, inflammatory, immunological disease. In contrast to skin lesions, which are often self-limiting, oral lesions rarely heal on their own and can be resistant to local and systemic treatments. In this clinical trial, hyaluronic acid (HA) was mixed with triamcinolone for intralesional injection to reduce side effects in the treatment of OLP. This randomized clinical trial with a split-mouth design was performed on 28 patients with OLP. The mouth was divided randomly into two sides: a test side, which received HA combined with triamcinolone, and a control side, which received triamcinolone alone. The rate of symptom recurrence was 74.1% on the control side and 11.1% on the test side (significant difference, P

Purpose To research whether serum vascular endothelial growth factor (VEGF) levels could be used to evaluate diabetic retinopathy (DR) progression and to compare vitreous VEGF levels after injections of intravitreal bevacizumab (IVB), ranibizumab (IVR), and triamcinolone acetonide (IVTA) in proliferative diabetic retinopathy (PDR). Methods We enrolled a total of 91 eyes of 89 subjects (70 eyes of 68 diabetics and 21 eyes of 21 nondiabetic controls). The diabetic subjects were divided into three groups as PDR (n=28), non-proliferative diabetic retinopathy (n=20), and no-DR (n=20). Eyes with PDR (n=31) were injected with IVB (n=7), IVR (n=10), or IVTA (n=6) 3 days before vitrectomy, and eight eyes did not receive an injection. Serum and vitreous samples were collected before vitrectomy and analyzed using ELISA. Results We found the severity of retinopathy was not correlated with serum VEGF levels (P=.919, ρ=−0.011). Compared with the controls, vitreous VEGF was higher in the PDR (P

In certain cases, there may be firm adherence of the cortical vitreous to the retinal surface during pars plana vitrectomy. This report aims to present an alternative method of posterior vitreous detachment (PVD) induction at the macula with the use of a flexible loop.A 5-year-old girl underwent 25-gauge pars plana vitrectomy for optic pit maculopathy. Triamcinolone is used for staining. Posterior vitreous detachment was induced in the perifoveal area with 360° radial peeling. The vitrector was then used to lift and complete the PVD.Posterior vitreous detachment was able to be induced with minimal trauma to the retinal surface. There were no postoperative complications from the procedure.Posterior vitreous detachment induction at the macula using a flexible loop and radial stripping is a safe and reliable alternative to conventional techniques.

In this study, modified kappa-carrageenan/pectin hydrogel patches were fabricated for treatment of buccal fungal infections. For this purpose, kappa-carrageenan-g-acrylic acid was modified with different thiolated agents (L-cysteine and 3-mercaptopropionic acid), and the thiol content of the resulting modified kappa-carrageenan was confirmed by elemental analyzer. Then, the hydrogel patches were fabricated, and characterized by Fourier-transform infrared spectroscopy, thermogravimetric analysis, ex vivo mucoadhesion test, and swelling behavior. Triamcinolone acetonide was added either directly or by encapsulating within the poly(lactic-co-glycolic acid) nanoparticles. The release amount of the drug from the directly loaded patch was 7.81 mg/g polymer, while it was 3.28 mg/g polymer for the encapsulated patch with the same content at 7 hr. The hydrogel patches had no cytotoxicity by cell culture studies. Finally, the drug loaded hydrogel patches were demonstrated antifungal activity against Aspergillus fumigatus and Aspergillus flavus. These results provide that the novel modified kappa-carrageenan and pectin based buccal delivery system has promising antifungal property, and could have advantages compared to conventional buccal delivery systems.

Purpose To assess the occurrence of peripheral vitreoschisis-induced vitreous cortex remnants (p-VCRs) in primary rhegmatogenous retinal detachment (RD) and investigate whether the presence of p-VCRs results in a greater risk of RD recurrence, secondary to Proliferative Vitreoretinopathy (PVR) development after pars plana vitrectomy (PPV). Methods Patients who underwent PPV for primary rhegmatogenous RD between January 2016 and December 2018 were included. The presence of residual p-VCRs was confirmed intraoperatively using triamcinolone acetonide (TA). Patients with p-VCRs were divided into two groups: Group A comprised of patients who underwent PPV without p-VCR removal, while Group B included patients who underwent PPV with p-VCR removal. Results Four hundred-thirteen eyes with evidence of p-VCR were analyzed. Two-hundred-twenty-three eyes underwent PPV without VCR removal (Group A), while 190 eyes underwent PPV with p-VCR removal (Group B). Primary anatomical success was 91.5% in the Group A and 95.4% in the group B. Retinal re-detachment due to PVR occurred in 17 (7.6%) eyes in Group A and in four (2.1%) eyes in Group B within the first 3 months (p = 0.01). Among group A, in 11 eyes, there was a diffuse posterior PVR grade C, while six eyes were focal PVR grade C. In Group B, we observed four retinal re-detachment due to focal PVR grade C. Conclusion The presence of p-VCRs seems to be associated with a higher incidence of PVR development and might also result in more complex RD recurrence, this suggests the need for more aggressive VCRs removal during the first surgery.

Background Benign vocal fold lesions (BVFLs) can cause voice changes, including reduced loudness and pitch range. In recent times, with progression in endoscopic technology, office-based vocal fold steroid injection (VFSI) has been used as an alternative therapy for BVFLs. Aims/objectives In this study, we analyzed the efficacy and safety of VFSI to investigate the mechanism underlying its therapeutic effects and determine the conditions in which VFSI will be most effective. Materials and methods In this retrospective cohort study, we included 40 condition-matched patients (8 patients per lesion) with chorditis, vocal nodules, vocal polyps, Reinke's edema (RE), or vocal scars who received similar regimens of steroid injection using a commercial preparation of triamcinolone acetonide. Their phonological outcomes were evaluated 2 or 3 months after the injection. Results Significant improvements were observed in Voice Handicap Index scores, results of laboratory voice evaluation, and voice quality measured using the Grade, Roughness, Breathiness, Asthenia, Strain scale in all participants. In subgroup analysis, VFSI was highly effective against chorditis and vocal nodules, but less effective against RE and vocal scars. Conclusions Single-dose VFSI is valuable as an alternative to voice rehabilitation and laryngo-microsurgery, but higher concentrations or repeated injections are required for intractable lesions.

The case is presented on a young Honduran female with no medical history of note, who presented with multiple areas of exudative retinal detachment (RD), and a best-corrected visual acuity of 1.3logMAR in both eyes. She was diagnosed with incomplete Vogt-Koyanagi-Harada syndrome, and treated early with a combination of intravenous therapy with 1g of prednisolone per day for 3 days, as recommended by published evidence, as well as mycophenolate mofetil (2g per day). During the corticosteroids tapering, there was a recurrence of exudative retinal detachments, and megadoses of 1g of intravenous corticosteroids per day were reintroduced for 6 days until the complete resolution of the fluid of the exudative RD, and cyclosporine (100mg per day), subtenon triamcinolone (40mg/mL), and intravitreal ranibizumab once a month in the both eyes were added to the treatment, with a great control of choroidal inflammation that resulted in the remission of symptoms and signs.

Background: Osteoarthritis (OA) of the peripheral joints is frequently related with physical disability and decline in health-related quality of life, deciphering into a significant burden on people and humankind. Although IA corticosteroid injections are being in clinical use, their long-term effects on knee OA are least studied and documented. Hence, the study was done with the aim of assessing the effect of intra-articular (IA) injection of corticosteroid in patients with OA of the knee. Methods: This prospective observational study was conducted over a period of 6 months between 40 years and 75 years with Grade I and II OA of the knee admitted under the Department of Orthopaedics, Tertiary Care Hospital, Belgaum. Patients' affected knee was injected with 80 mg of triamcinolone after the examination, and follow-ups had done at 2 weeks, 6 weeks, 3 months, and 6 months. The standard pro forma used were Visual Analog Scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Knee Injury and Osteoarthritis Outcome Score (KOOS). Results: The mean age of the participants was 58.96 ± 9.58, ranging from 40 to 75 years, with a slightly higher proportion of females. The proportion of Grade 1 and Grade II OA was 24% and 76%, respectively, and 54.7% had right-sided involvement. The difference between pre Rx: Pre intervention VAS score VAS score and follow-up periods at 2 weeks, 6 weeks, 3 months, and 6 months was statistically significant with respect to VAS scale, KOOS scale, and WOMAC scale (P < 0.001). Conclusion: there was no major adverse effect of corticosteroid injections, and it showed significant improvement in patients. There is a need to conduct large-scale well-controlled clinical trials with an appropriate control group, to be able to document the relative efficacy and safety of IA steroid injection.

Background Excipients are widely used in pharmaceuticals, detergents, food, and drink because of their properties of low toxicity and hypoallergenicity. The excipient carboxymethylcellulose is used extensively as a thickener in foods such as baked goods, ice cream, gluten free, and reduced fat products, where it may be labeled as e-number E466. However, excipients can rarely cause type 1 hypersensitivity reactions. Several publications have described systemic allergy following carboxymethylcellulose exposure in pharmaceuticals, particularly systemic corticosteroids. Furthermore, there is one reported case in the literature of anaphylaxis following food containing carboxymethylcellulose. Case presentation We identify a case of anaphylaxis in a 45-year-old atopic Caucasian woman on receiving an injectable suspension of the corticosteroid triamcinolone acetonide containing carboxymethylcellulose, and subsequent allergic symptoms on reexposure to carboxymethylcellulose in a commercial drink. Diagnosis of carboxymethylcellulose excipient allergy was confirmed through skin prick testing using Celluvisc carmellose 0.5% eye drops, which contain carboxymethylcellulose as the active ingredient. Conclusion This case highlights the importance of identifying excipients such as carboxymethylcellulose as causes of allergy, to reduce burden of further hypersensitivity reactions, not just to drugs but to other consumables.

Observing data on the characteristics of intra-articular injection of sodium citrate for knee osteoarthritis is an important reference value for human safety and evacuation design. To address the problems of slow data collection and poor accuracy of results of knee osteoarthritis behavior, under intensive conditions of intra-articular injection for knee osteoarthritis, this paper designs a data mining-based feature extraction system for intra-articular injection of sodium citrate for knee osteoarthritis. Using the Hadoop architecture, we extract the basic data of human behavior in the two-dimensional plane by storing and stitching the collected continuous data and discriminate the behavioral categories of knee osteoarthritis. We collected a real dataset from 84 patients with knee osteoarthritis treated in our hospital from October 2019 to October 2020. The dataset was divided into 42 patients in the tretinoin group and 42 patients in the sodium glutamate group according to the randomized number table method. The trimethoprim group was treated with intra-articular injection of trimethoprim, and the sodium citrate group was treated with intra-articular injection of sodium citrate. The clinical efficacy, joint mobility, intra-articular fluid volume, Lysholm score of knee joint, numerical pain intensity scale (NRS) score, and adverse effects of the two groups were compared before and after treatment. In our experiments, we observed that, compared with triamcinolone acetonide intra-articular injection, sodium hyaluronate intra-articular injection is more effective in the treatment of knee osteoarthritis. It can effectively improve knee function and reduce pain and adverse reactions.

Background Ultrasonography (US)-guided steroid injections can improve the accuracy of injection in patients with de Quervain disease, especially in those with an intracompartmental septum. Although the main lesion of de Quervain disease in patients with a septum is a stenosing tenosynovitis of the extensor pollicis brevis (EPB), no report we know of has compared injection into the EPB subcompartment with an injection into both the abductor pollicis longus (APL) and EPB subcompartments. In this randomized trial, we compared the results of US-guided steroid injections targeting both subcompartments and the EPB subcompartment alone in patients with de Quervain disease. Questions/purposes (1) Do patients who receive a steroid injection in the EPB subcompartment alone have lower pain scores at 6 weeks and at 3 months after US-guided injection compared with patients who receive an injection in both subcompartments? (2) Do patients who receive a steroid injection in the EPB subcompartment alone experience fewer steroid injection-related complications than patients who receive an injection in both subcompartments? Methods A randomized controlled study was performed at a single center between August 2018 and March 2021. Patients with a diagnosis of de Quervain disease and with a complete intracompartmental septum between the APL and the EPB tendons were included. In total, 112 patients had a diagnosis of de Quervain disease during the study period. Definite, complete subcompartmentalization was seen in 50 patients. Patients were randomly assigned to US-guided injections targeting both subcompartments (n = 25) or the EPB subcompartment alone (n = 25). There were no between-group differences in age, gender, affected wrist, or disease duration, and all patients had US evidence of tendinosis of the EPB, with or without tendinosis of the APL. Although 33% of patients (16 of 48) showed tendinosis of the APL, no patient showed tendinosis of the APL alone. In all patients, a dorsal-to-palmar side injection of 0.5 mL of 2% lidocaine and 0.5 mL of triamcinolone acetonide (40 mg/mL) was administered by two experienced hand surgeons. In the both-subcompartments group, US-guided injections were performed in each of the APL and EPB subcompartments. In the EPB subcompartment group, US-guided injections were administered in the EPB subcompartment only. All patients underwent the same protocol after the procedure. Four percent (n = 2, 1 in each group) of patients were excluded after randomization because their pain level was not registered. Pre- and postinjection clinical outcome assessments were completed by orthopaedic surgery residents not involved in patient management. Patients were regularly examined at baseline, 6 weeks, and 3 months to evaluate the intensity of pain. We assessed pain by the VAS score, where 0 indicated no pain and 100 the most pain. At baseline, the VAS score was 67 ± 14 in the both-subcompartment group and 67 ± 16 in the EPB subcompartment group (mean difference 0.17 [95% CI -8.45 to 8.82]; p = 0.97). Complications related to the steroid injection, including numbness, tendon rupture, and skin hypopigmentation, were also recorded at final follow-up examinations. To determine statistical power, the VAS score for pain at 6 weeks after the injection was used as the primary outcome variable. The minimum clinically important difference for the VAS score was deemed to be 20 mm, and we estimated an SD of 23. A sample size calculation indicated that a sample of 21 patients per group would provide 80% power to detect an effect of this size between the groups at the p = 0.05 level using a t-test. Results There were no differences in the VAS scores between the both-subcompartment group and the EPB group at 6 weeks (10 ± 6 versus 10 ± 7, mean difference -0.08 [95% CI -4.08 to 3.91]; p = 0.97). The same was true at 12 weeks (12 ± 13 versus 11 ± 15, mean difference 0.38 [95% CI -7.74 to 8.49]; p = 0.09). No adverse events related to treatment (such as tendon rupture, infections, and numbness) occurred in either group. However, skin hypopigmentation occurred at the final follow-up examination in both groups. The proportion of patients experiencing skin hypopigmentation in the EPB subcompartment group was lower than in the both-subcompartment group (33% [8 of 24] versus 67% [16 of 24]; odds ratio 0.25 [95% CI 0.08 to 0.83]; p = 0.02). Conclusion Our data suggest that a US-guided steroid injection targeting the EPB subcompartment alone is as effective in terms of pain reduction as targeting both subcompartments in patients with de Quervain disease who have complete septation. Furthermore, an injection targeting the EPB subcompartment alone can reduce the dose of steroids used, perhaps thereby decreasing complications related to steroid injections. We recommend using only single-compartment injections in this context, even among patients with an intracompartmental septum. Level of evidence Level I, therapeutic study.

Background Cytomegalovirus (CMV) retinitis may occur in non-HIV individuals following systemic immunosuppressive treatment or periocular corticosteroid administration. However, simultaneous multiple viral retinitis is rare in HIV-negative individuals. We report a case of dual viral retinitis in a non-HIV female on systemic immunosuppressive for pemphigus vulgaris who was administered a periocular corticosteroid injection. Method A 32-year-old female on double immunosuppressive therapy (prednisolone and cyclophosphamide) for pemphigus vulgaris, presented with gradual painless diminution of vision in the right eye for one month. She was initially diagnosed to have possible autoimmune neuroretinitis by the referring ophthalmologist and received a single injection of posterior subtenon triamcinolone acetonide for the same. Her vision however deteriorated further and she received an intravitreal ganciclovir injection with a revised diagnosis of CMV retinitis. Due to suboptimal response she was referred to us. Aqueous Polymerase chain reaction (PCR) revealed dual positivity for CMV and Herpes simplex virus. She was successfully managed with intravitreal ganciclovir injections, systemic acyclovir and tapering of systemic immunosuppressive drugs. Result The retinitis lesions resolved gradually leaving behind a pale optic disc and foveal atrophy at 12 weeks follow-up. Conclusion Infective etiology must be ruled out in immunosuppressed patients before considering periocular corticosteroids. Dual viral involvement, although rare, may cause fulminant retinitis in predisposed individuals. High index of suspicion and PCR from ocular fluids should be performed at the earliest in patients with atypical or poorly responding retinitis lesions.

Intralesional corticosteroids are used to treat various dermatologic conditions through direct delivery of medication to the target tissue. Although intralesional corticosteroids are generally well tolerated, their side effects include atrophy, dyspigmentation, and, infrequently, infection, hemorrhage, and hypersensitivity.1, 2, 3 Corticosteroid injection site atrophy and dyspigmentation due to dermatologic use have been estimated to have an incidence of 0.5%.1, 2, 3 Dyspigmentation is noted more prominently in patients with skin of color and generally resolves within weeks to months.2 Cutaneous atrophy usually begins within 2-3 months of an injection and resolves in 1-2 years, although it has been reported to persist beyond 5 years.1, 2, 3 Previous studies have demonstrated improvement in steroid-induced lipoatrophy of the face, buttocks, and extremities following intralesional saline injections.1,4, 5, 6, 7 We present a case of severe steroid-induced hypopigmentation and cutaneous atrophy due to intralesional triamcinolone treatment of a supraumbilical keloid treated successfully with serial intralesional saline injections.

Background To evaluate the efficacy and safety of different intravitreal corticosteroids for treating diabetic macular edema (DME). Methods Four databases were systematically searched for randomized controlled trials comparing different intravitreal corticosteroids for treating DME. The primary outcome was the change in best-corrected visual acuity (BCVA) within 6 months after the first injection (short-term BCVA). Secondary outcomes were the change in BCVA over 1 year (long-term BCVA) and changes in central macular thickness (CMT) and intraocular pressure (IOP) within 6 months after the first injection. Network meta-analysis was performed to aggregate the results from the individual studies. Results Nineteen trials involving 2839 eyes were included. Intravitreal triamcinolone acetonide (TA) injections (≥ 8 mg and 4–8 mg), fluocinolone acetonide (FA) implants (0.5 µg/day) and dexamethasone (DEX) implants (700 µg) improved short-term BCVA (mean changes in logMAR [95% confidence interval] − 0.27 [− 0.40, − 0.15]; − 0.12 [− 0.18, − 0.06]; − 0.10 [− 0.21, − 0.01]; and − 0.06 [− 0.11, − 0.01]). Intravitreal TA injections (4 mg, multiple times), FA implants (0.5 µg/day and 0.2 µg/day), and DEX implants (350 µg) improved long-term BCVA (mean changes in logMAR [95% confidence interval] − 0.11 [− 0.21, − 0.02]; − 0.09 [− 0.15, − 0.03]; − 0.09 [− 0.14, − 0.02]; and − 0.04 [− 0.07, − 0.01]). All intravitreal corticosteroids reduced CMT, and different dosages of TA did not show significant differences in increasing IOP. Conclusions Intravitreal corticosteroids effectively improved BCVA in DME patients, with higher dosages showing greater efficacies. TA was not inferior to FA or DEX and may be considered a low-cost alternative choice for DME patients. The long-term efficacy and safety of different corticosteroids deserve further investigation.

To evaluate the effectiveness of non-surgical treatment as an alternative in the management of central giant cell granuloma (CGCG). A literature search was carried out in accordance with the PRISMA statement in order to answer the question “Are non-surgical treatments effective as an alternative in the treatment of CGCG?”. Two examiners independently assessed eligibility, risk of bias, and extracted data, which included therapeutic protocol, side effects, and need for surgical supplementation. Among 1712 studies, 15 were included, totaling 145 patients. Calcitonin, intralesional corticosteroids, and denosumab were the medications used. For calcitonin (n = 61), complete remission was found in 30 cases. For intralesional triamcinolone (n = 68), reduction in size was observed in most cases (n = 39). Four cases received subcutaneous denosumab and showed absence of active bone metabolism in the region, of which three presented ossification. Combination of drug therapies (n = 29) was reported in one study and included subcutaneous interferon and oral imatinib. More and less side effects were found for interferon and corticosteroids, respectively. Forty percent of patients required additional surgical treatment. Despite the side effects presented and the need for additional surgery in some patients, in general, all non-surgical treatments could provide positive results as an alternative for the management of CGCG, especially with regard to reducing the size of the lesion. CGCG is a benign bone lesion that mainly affects young individuals. Although the most common therapy is surgery, its contraindication in some patients, the large extension, and high recurrence rate of the aggressive variant have led the search for non-surgical therapies.
