Recently, a third type of dentigerous cyst, associated with an exostosis arising from the temporal bone, has been described. Today, computed tomography (CT) is often available and provides detailed information about the exact location and extent of dentigerous cysts, allowing for the description of new findings.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Study design&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;This is a case series outlining the clinical, radiographic and computed tomographic features of dentigerous cysts in seven horses presented to the Equine Clinic at the Vetsuisse Faculty, University of Zurich, Switzerland.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Objectives&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The aim of this case series was to describe the radiographic and computed tomographic findings, and the occurrence of exostoses arising from the temporal bone, in horses with dentigerous cysts.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The medical records of the Equine Hospital at the University of Zurich were reviewed for horses admitted with dentigerous cysts between 2007 and 2023.

Clinical signs of thrush can range from black exudate in the sulci of the frog accompanied by a foul odour to bacterial invasion of the frog corium and digital cushion resulting in lameness. Thrush is primarily encountered in a conformationally compromised hoof capsule that is generally associated with an unhealthy frog. As thrush is rarely encountered in a healthy frog, it is important to focus on the farrier practices that may play a role in both the pathogenesis of thrush and its prevention.

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":"36 12","pages":"638-645"},"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}

Vissani","doi":"10.1111/eve.14059","DOIUrl":"10.1111/eve.14059","url":null,"abstract":"<div>\u0000 \u0000 <p>Equine coital exanthema (ECE), caused by Equid alphaherpesvirus 3 (EHV-3), is a highly contagious, venereally transmitted mucocutaneous disease, characterised by the formation of papules, vesicles, pustules and ulcers on the external genital organs of mares and stallions. The infection is endemic worldwide, and the virus is transmitted mainly through direct contact during sexual intercourse and by contaminated instruments during reproductive manoeuvres in breeding facilities. The only known biological reservoir of EHV-3 is the latently infected horse; it is well-known that, as for other herpesviral infections, periods of reactivation from latency, with production and shedding of infectious virus, are the source of infection for other comingling susceptible animals. Episodes of reactivation and shedding, either with or without clinical manifestation, and together with variable levels of serum antibodies, have been observed. Although the disease is relatively benign and does not result in systemic illness, infertility or abortion, it does have a negative impact on the equine industry, as it forces to temporarily withdraw affected animals, consequently disrupting mating activities in breeding enterprises. Thus, outbreaks of ECE continue to be a major problem for the equine industry, mostly in those facilities with heavily scheduled breeding calendars during reproductive seasons. For affected stallions, such disruptions may translate into significant end-of-season decreases in the mare-book size. Similarly, affected mares may miss breeding opportunities. In artificial insemination and embryo transfer centres, affected mares may be reluctant to be inspected, inseminated or transferred, with the consequent loss of opportunities to become pregnant. In both scenarios (natural mating or artificial insemination), delayed foaling dates or reduced pregnancy rates may occur in mares that miss breeding opportunities because of the disease. In the interest of reducing the negative impact of EHV-3 infections on breeding centres, advances have been made during the last years as to diagnostic methodologies, treatment and prevention.</p>\u0000 </div>","PeriodicalId":11786,"journal":{"name":"Equine Veterinary Education","volume":"37 1","pages":"13-16"},"PeriodicalIF":0.8,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142764426","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}
