Tears of the MF have been described associated with cases of nonseptic tenosynovitis presenting with lameness, with ponies and cobs being over-represented. Ultrasonography and contrast tenography are the predominant imaging modalities used to diagnose tears of the MF, with tenoscopic evaluation still serving as the gold standard. However, the sensitivity and specificity of additional techniques such as contrast computed tomographic tenography and MRI are now being investigated as other modalities that could be of value to identify MF tears. Additional techniques have been described to combine with traditional ultrasonography, with the aim to improve the sensitivity of identifying MF tears, such as dynamic extension/flexion techniques and saline injections of the DFTS. The overall aim of this paper was to review current evidence to determine the best noninvasive diagnostic imaging modality, with a high sensitivity and specificity, to more accurately diagnose MF tears and aid more thorough surgical planning.</p>\u0000 </div>","PeriodicalId":11786,"journal":{"name":"Equine Veterinary Education","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588101","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}

{"title":"Zuclopenthixol decanoate toxicity","authors":"Janny C. de Grauw,&nbsp;Gemma Pearson","doi":"10.1111/eve.14045","DOIUrl":"https://doi.org/10.1111/eve.14045","url":null,"abstract":"&lt;p&gt;A psychopharmaceutical describes a drug that has an impact on the mental state of the user. These medications are often used preventively to modify the behavioural response to stress in ungulate prey species, for example, to facilitate transportation and/or introduction into a new area, group or herd. Zuclopenthixol is a long-acting neuroleptic (LAN) or antipsychotic agent that has been used to facilitate wildlife translocation in conservation projects. In human medicine, this drug is used to treat psychiatric disorders including schizophrenia and psychosis. It is a long-acting dopamine D1 and D2 receptor antagonist, with a duration of action of 3–4 days (acetate ester) up to 2–3 weeks (decanoate) in wild ungulates, depending on the pharmaceutical formulation (Swan, &lt;span&gt;1993&lt;/span&gt;; Read, &lt;span&gt;2002&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Our understanding of equine behaviour and in particular learning theory, has deepened over the past few years. We now recognise that most problematic behaviours can quickly be resolved with appropriate training (McLean &amp; Christensen, &lt;span&gt;2017&lt;/span&gt;; Pearson, &lt;span&gt;2019&lt;/span&gt;) and this knowledge should markedly reduce the need for psychopharmaceutical use during the routine management of horses. Yet, as this knowledge is still not embedded into mainstream equestrianism, and considering we know most people overestimate their understanding of horse behaviour (Warren-Smith &amp; McGreevy, &lt;span&gt;2008&lt;/span&gt;; Wentworth-Stanley, &lt;span&gt;2013&lt;/span&gt;; Pearson et al., &lt;span&gt;2020&lt;/span&gt;), psychopharmaceuticals remain an attractive option to many. Moreover, some problematic behaviours coincide with marked levels of emotions such as fear, which impairs a horse's ability to learn. By directly reducing fear, judicious psychopharmaceutical use may optimise retraining, improve welfare and maximise safety.&lt;/p&gt;&lt;p&gt;When it comes to pharmacological behavioural modification in horses, there is an intricate ethical balance between safely promoting equine welfare during stressful events versus the inherent risks of abuse. Antipsychotics like zuclopenthixol are also classified as neuroleptics or major tranquilisers, as they superficially appear to reduce agitation and have a resultant calming effect. This is why this class of drug has a high potential for abuse in equine sports. They have been denoted ‘banned substances’ by the Fédération Equestrian Internationale (FEI) as they are considered to have no legitimate use in equine medicine (FEI equine prohibited substance list, https://inside.fei.org/fei/cleansport/ad-h/prohibited-list), and they are likewise prohibited in horseracing (International Federation of Horseracing Authorities, International Agreement on Breeding, Racing and Wagering, &lt;span&gt;2018&lt;/span&gt;). A true anxiolytic reduces fear while allowing the animal to otherwise function normally, however, antipsychotics reduce motor activity and blunt all emotional responsiveness (Cromwell-Davies &amp; Landsberg, &lt;span&gt;2018&lt;/span&gt;).

However, severe constriction or adhesions within the fetlock canal can restrict manoeuvrability and access of instruments within the sheath, preventing safe and effective transection of the ligament. This case report describes the successful use of a hook knife via a subcutaneous approach to safely transect the PAL under tenoscopic visualisation in a horse where severe constriction of the fetlock canal prohibited the standard intrathecal approach.

The mare was 8 months pregnant and experienced intermittent unresponsive colic signs. Rectal examination revealed clockwise 180° UT and ultrasonography showed a viable fetus. The haematological findings were within the normal range. The mare was surgically treated immediately by standing flank laparotomy (SFL) on the right side. 4 days later, the mare was returned to the clinic with the same complaint. Rectal and ultrasonography examinations revealed counterclockwise 180° UT and a viable fetus. The animal was subjected again to SFL on the left side. After surgeries, the mare recovered well, foaled at term and gave birth to a viable filly. She was bred again and conceived. This case is documented to demonstrate the occurrence of a UT in both directions during the same gestation period in mares, as well as the efficacy of SFL in rectifying the condition and allowing both the mother and foal to survive.","PeriodicalId":11786,"journal":{"name":"Equine Veterinary Education","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141928471","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}
