The aim of this study was to evaluate the reliability, content, and quality of videos for patients available on YouTube for learning how to self-administer subcutaneous anti-tumour necrosis factor (TNF) injections. We searched for the terms Humira injection, Enbrel injection, Simponi injection, and Cimzia injection. Videos were categorised as useful information, misleading information, useful patient opinion, and misleading patient opinion by two physicians. Videos were rated for quality on a 5-point global quality scale (GQS; 1 = poor quality, 5 = excellent quality) and reliability and content using the 5-point DISCERN scale (higher scores represent greater reliability and more comprehensive videos). Of the 142 English videos, 24 (16.9%) videos were classified as useful information, 6 (4.2%) as misleading information, 47 (33.1%) as useful patient opinion, and 65 (45.8%) as misleading patient opinion. Useful videos were the most comprehensive and had the highest reliability and quality scores. The useful information and useful patient opinion videos had the highest numbers of views per day (median 8.32, IQR: 3.40-14.28 and 5.46, IQR: 3.06-14.44), as compared with 2.32, IQR: 1.63-6.26 for misleading information videos and 2.15, IQR: 1.17-7.43 for misleading patient opinion videos (p = 0.001). Almost all (91.5%) misleading videos were uploaded by individual users. There are a substantial number of English-language YouTube videos, with high quality, and rich content and reliability that can be sources of information on proper technique of anti-TNF self-injections. Physicians should direct patients to the reliable resources of information and educate them in online resource assessment, thereby improving treatment outcomes.

ObjectiveThe aim of this study was to compare the efficacy of extracorporeal shock wave therapy (ESWT) and therapeutic ultrasound (US) in the treatment of lateral epicondylosis (LE).MethodsOur study enrolled 50 patients with LE. Patients were randomized into two groups. Group 1 underwent therapeutic US (n = 24; 5 males and 15 females; mean age: 43.75 ± 4.52) Group 2 underwent ESWT (n = 20; 8 males and 16 females; mean age: 46.04 ± 9.24). Patients were evaluated at baseline, after treatment,and 1 month following treatment. The outcome measures were the visual analog scale (VAS), algometer, grip dynamometer, quick-disability of the arm,shoulder,and hand (QDASH), patient-rated tennis elbow evaluation (PRTEE), and Short Form-36 (SF-36) health survey questionnairre.ResultsBoth groups showed significant improvements in terms of VAS (all p values < 0.0001), dynamometer (p = 0.001 vs p = 0.015), algometer (all p values < 0.0001), PRTEE (all p values < 0.0001), QDASH (all p values < 0.0001), and SF-36 scores (p = 0.001 vs p = 0.005) within time. There was no significant difference between the two groups, except algometer scores in favor of ESWT (p = 0.029).ConclusionESWT and therapeutic US are equally effective in treating LE. ESWT is an alternative therapeutic intervention and as effective as US.Level of evidenceLevel III, Therapeutic study.

Background and PurposeWe determined the reliability of ultrasonography (US) measurements for diagnosing carpal tunnel syndrome (CTS) and their correlation with symptom duration and electrophysiology findings. We determined whether the ratio of the median-to-ulnar cross-sectional areas (CSAs) can support CTS diagnoses.MethodsThe pisiform CSA (CSApisiform), swelling ratio (SR), palmar bowing, and CSApisiform/ulnar CSA (CSAulnar) measurements made in two subgroups of CTS patients (having sensory affection alone or having both sensory and motor affection) were compared with controls. CSAulnar was measured in Guyon's canal at the level of most-protuberant portion of the pisiform bone.ResultsThe values of all of the measured US parameters were higher in patients with CTS (n=50) than in controls (n=62). CSApisiform could be used to diagnose CTS of mild severity. All of the parameters were positively correlated with the distal latency of the compound muscle action potential, and all of them except for SR were negatively correlated with the sensory nerve conduction velocity. A CSApisiform/CSAulnar ratio of ≥1.79 had a sensitivity of 70% and a specificity of 76% for diagnosing CTS.ConclusionsOnly CSApisiform measurements were reliable for diagnosing early stages of CTS, and CSApisiform/CSAulnar had a lower diagnostic value for diagnosing CTS.
