A high-speed treadmill videoendoscopic examination including tracheal airway pressure measurements was performed. Grade C left recurrent neuropathy was diagnosed and a prosthetic laryngoplasty was performed. Following surgery, the horse went back into training and eventually racing and performed well in its first two starts. Ten and a half months later the horse re-presented with abnormal respiratory noise, and poor performance had returned. Therefore, the examination was repeated. This revealed that the left arytenoid cartilage was in a similar abducted position as immediately after prosthetic laryngoplasty surgery. However, right-sided arytenoid paresis was present as well as bilateral aryepiglottic fold collapse and right vocal fold collapse. Bilateral aryepiglottic fold resection and right vocal cordectomy was performed using a diode laser under standing sedation. The horse presented a third time, four and a half months later. At this point, the horse had developed right arytenoid paralysis, and it was euthanised. Necroscopy and histopathological examinations were performed. The right cricoarytenoideus dorsalis muscle was moderately reduced in size and showed signs of denervation atrophy. There was loss of normal myelinated fibres of both recurrent laryngeal nerves as well as evidence of active degeneration of the right recurrent laryngeal nerve. In the way the horse sequentially developed first left-sided then right-sided arytenoid paralysis, combined with histological evidence of nerve degeneration, a diagnosis of ‘clinical’ bilateral idiopathic recurrent laryngeal neuropathy was established.</p>","PeriodicalId":11786,"journal":{"name":"Equine Veterinary Education","volume":"37 6","pages":"e98-e104"},"PeriodicalIF":0.8,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eve.14089","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143913989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the last decade, intra-articular 2.5 iPAAG has shown to be a potent and promising drug in the medication of OA in horses, as no other single medical treatment for OA has such prolonged efficacy. Preliminary observations on the mechanisms of action of intra-articular 2.5 iPAAG support a mechanical effect through integration into the synovial membrane, an increase in joint elasticity possibly reducing overall joint capsule stiffness, and provision of lasting viscosupplementation which contributes to protecting articular surfaces. Because 2.5 iPAAG is an inert and biocompatible hydrogel, no effects on arthrocentesis cytology parameters have been observed. Studies also suggest that the positive effects of 2.5 iPAAG occur in the absence of intra-articular neurotoxicity or fibrosis, with a low-level macrophage-driven foreign body response. The effect on the synovial membrane and joint capsule and the long-acting viscosupplementation represent new concepts in the management of equine OA.</p>\u0000 </div>","PeriodicalId":11786,"journal":{"name":"Equine Veterinary Education","volume":"37 3","pages":"161-168"},"PeriodicalIF":0.8,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143253387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radiographic evaluation revealed a well-defined radiolucency within the proximal third of the left third metacarpal bone, localised to the enthesis of the proximal suspensory ligament. Ultrasonographic findings demonstrated moderate thickening and increased vascularity of the suspensory ligament at this level. Surgical intervention was considered; however, its feasibility was constrained by the atypical nature and location of the lesion. Subsequent magnetic resonance imaging (MRI) provided a detailed characterisation of the lesion, confirming its expansile nature and the suspected associated avulsion fracture presence. Histopathological examination corroborated the diagnosis of an aneurysmal bone cyst (ABC) with an accompanying bone fracture and bone remodelling. Cases like the one described here define the importance of utilising advanced imaging techniques in combination with conventional modalities, especially when diagnosing and assessing the extent of unusual or complex lesions, to inform prognosis and guide treatment decisions.
