Intratracheal Leiomyosarcoma in a 13-Year-Old German Riding Pony Mare. A 13-year-old German Riding Pony mare was referred for evaluation of progressive respiratory noise and mixed dyspnoea, which rapidly deteriorated to respiratory distress. Clinical examination revealed marked rattling inspiratory and expiratory tracheal sounds and severe, rattling, vesicular lung sounds. Arterial blood gas analysis demonstrated moderate hypoxaemia (partial pressure of arterial oxygen 76 mmHg at rest). Upper airway endoscopy identified a pink, cauliflower-like pedunculated mass originating from the dorsal tracheal wall approximately 15 cm cranial to the tracheal bifurcation, cau...
Quantitative Bone Scintigraphic Follow-Up After a 2-Month Cross-Training Program Including Swimming in Showjumping Horses with Back and Neck Pain. To quantitatively describe changes in skeletal radiopharmaceutical uptake during a training program including swimming in horses with neck and back pain, eighteen showjumping horses with documented vertebral lesions were prospectively included in a training program composed of 4 weeks of ridden work and then 8 weeks combining swimming and ridden exercise. Previously published data on this cohort did not demonstrate any clear change in thoracolumbar mobility. Bone scintigraphy was performed at the 4th and 12th weeks. Radiopharmaceutical uptake was quantified in 205 regions of interest (ROIs) an...
A retrospective study of catastrophic pelvic fractures in California Thoroughbred racehorses. Here, we describe and characterize catastrophic pelvic fractures in Thoroughbred racehorses in California. We reviewed retrospectively racehorse autopsy reports from horses that died spontaneously or were euthanized because of complete pelvic fractures in California between 1992 and 2018. The exercise history of affected horses was compared with eventmatched control horses. Catastrophic pelvic fractures were sustained by 133 horses. Pelvic fractures were 2.7% of all musculoskeletal fatalities. Pelvic fractures occurred during training (48.0%), racing (35.0%), and non-exercise (17.0%). Horses â...
Energy Metabolism Dysregulation in Horses and Foals. Dysregulation of energy metabolism occurs in horses and foals with transient systemic illness, malnutrition, or chronic metabolic diseases. The pathophysiologic processes resulting in energy dysregulation are important to interpret, understand, and appropriately monitor laboratory abnormalities associated with various disease states (hypoglycemia and hyperglycemia), as well as to aid in the management of energy dysregulation through nutritional and medical management.
Infrared Thermographic Assessment of Exercise-Induced Changes in Local Surface Temperature in Horses Following Treadmill Training: Preliminary Findings.

Infrared thermography has emerged as a non-invasive technique for assessing these thermal responses in horses. The present study aimed to evaluate the ability of infrared thermography to detect changes in mean local surface temperature and to qualitatively assess alterations in thermal distribution patterns following treadmill exercise. Methods: Three clinically healthy Warmblood horses were monitored over 10 consecutive training s...
Efficiency of a Combination of Polyethylene Glycol and Psyllium on the Evacuation of Sand Compared to Established Treatment Regimes in Sand Enteropathy of the Horse. The accumulation of sand in the abdomen is a rising risk for colic in horses. Sand mainly accumulates in the ascending colon in the cranioventral abdomen. Evacuation of sand is facilitated by the application of psyllium supported with a laxative via nasogastric intubation. Laxatives currently used are either sodium sulfate/magnesium sulfate or mineral oil. The aim of this study was to compare the efficiency of polyethylene glycol, a laxative already used in human medicine for chronic constipation, with that of the above-described, established therapy options. Therefore, 44 horses diagnosed wit...
Use of extracorporeal hemoperfusion in a 2-day-old foal with neonatal sepsis. A 2-day-old Miniature Horse filly presented with severe clinical and clinicopathologic findings consistent with neonatal sepsis, failure of transfer of passive immunity, and aspiration pneumonia. The filly initially was treated with broad spectrum antimicrobials, hemodynamic support, and hyperimmune plasma. Because of a lack of improvement within the first 24Â h, extracorporeal blood purification and cytokine removal were implemented. The foal underwent hemoperfusion (HP) using a polymer-based device (VetResQ). Reported notable changes during and after treatment included improved physical exam...
Concurrent Small Intestinal Neoplasia And Large Colon Volvulus In A Standardbred Yearling. Large colon volvulus is a common, life-threatening cause of colic in horses. Gastrointestinal neoplasia is a rare cause of abdominal pain in young horses. A 1-year-old Standardbred colt presented with acute colic unresponsive to medical treatment. An exploratory laparotomy identified extensive gastrointestinal pathology, and euthanasia was elected due to a poor prognosis. Necropsy revealed a 360-degree volvulus of the caecum and large colon with adhesions, enterotyphlocolitis, and a well-circumscribed mesenteric mass arising from the small intestine. Histopathology in combination with immunohi...
Pelvic axial rotation in hindlimb lame horses changes after diagnostic analgesia. Visual assessment of mild to moderate hindlimb lameness has low sensitivity and specificity, potentially leading to flawed diagnostic procedures. Pelvic axial rotation (roll) makes the assessment more complex but is also a potential source of information. Objective: To describe pelvic roll patterns in horses with unilateral hindlimb lameness before and after diagnostic analgesia. Methods: Retrospective study. Methods: Optical motion capture data from 20 horses with unilateral hindlimb lameness before and after successful local analgesia (assessed visually and objectively) were retrospectively ...
Choice for the horse is paramount: Owners’ experiences in facilitating friends, forage, and freedom in their management practices. Owned horses rely on people for their behavioural needs, such as access to conspecifics, constant access to low nutrient density, fibrous forage and freedom of movement; otherwise known as friends, forage and freedom (3Fs). Restricting the 3Fs prevents horses from achieving optimal welfare. We carried out 14 semi-structured interviews in the UK and Ireland to examine horse owners' experiences, attitudes and beliefs around the provision of the 3Fs. Most participants were female, aged from 25 to 65 years, resident in the UK and kept their horse at a livery facility. A reflexive thematic analysis...
Antibody kinetics against tetanus toxoid before and after primary vaccination of foals. Vaccination recommendations for foals against Clostridium tetani vary. Available studies assessing foal immune responses, maternal antibody interference, or individual variation often used small foal numbers. Objective: To quantify antibody responses after tetanus vaccination in foals and explore associations with passively transferred tetanus antibodies. Methods: Longitudinal cohort study. Methods: Sixty-two Warmblood foals from a single stud farm were followed from birth to 360 days of age. Foals received tetanus vaccinations at day 180 (d180) and d220 of life. Serum samples were collected...

Horse Anatomy and Art: Carlo Ruini. Carlo Ruini's Dell'Anotomia et dell'infirmità del cavallo (1598) is widely regarded as the first scientific treatise on veterinary anatomy. This paper reviews the historical circumstances of its composition and printing history, the structure and scientific content of its five anatomical books, the long-standing controversy over Ruini's authorship - including the plagiarisms it subsequently suffered - and the disputed attribution of its woodcut illustrations to artists such as Leonardo da Vinci, Titian and Agostino Carracci. Ruini's description of the pulmonary circulation is situated within ...
Cycle length variation assists in differentiation of atrial, ventricular, and sinus arrhythmias in horses at rest. Criteria for arrhythmia classification in horses are insufficient, particularly when differentiating atrial premature complexes (APCs) from sinus arrhythmia (SA). This study investigated RR and PP interval changes between SA, APCs, and ventricular premature complexes (VPCs). Unassigned: 30 resting ECGs were reviewed: 10 each containing SA, APC, and VPC. Sequences of 10 RR and PP intervals were recorded for each arrhythmia (20 events/ECG). Percent RR and PP deviations were calculated (1) between sequential intervals (%ΔSEQPP and %ΔSEQRR, respectively) and (2) compared to averaged baseline int...

Detection and confirmation of hypoxia-inducible factor activating agents in equine plasma and urine by liquid chromatography coupled to mass spectrometry. Hypoxia-inducible factor (HIF) activating agents can promote the transcription of the erythropoietin gene, enhancing an athlete's performance, and are therefore prohibited in sports. A liquid chromatography coupled to high-resolution mass spectrometry (LCHRMS) method was developed for the detection and confirmation of 11 HIF-activating substances in equine plasma and urine. Ammonium formate added to the mobile phase system suppressed the responses of all the analytes in either positive or negative ion mode and thus was not used. The starting organic percentage in the mobile phase gradient and ...
Russell’s viper envenomation in a 9-month pregnant mare saved with high-dose antivenom: a first-in-world case report. Snakebite during pregnancy is an uncommon but potentially catastrophic event, with maternal and foetal outcomes closely related to the severity of envenomation. While snakebite in pregnant women has been sporadically reported and is known to be associated with significant obstetrical complications, envenomation in animals, particularly in pregnant horses, is exceedingly rare. Only a few isolated cases of snakebite in horses have been documented, and to the best of our knowledge, snakebite in a pregnant mare has not been previously reported in the medical or veterinary literature. Russell's vip...
