    valgus

    What is the most likely diagnosis?
    annular ligament syndrome.
  • A 4-year-old mare is presented with discolouration around the nostrils, that occurred 3 weeks after recovering from an URT. She now presents with well demarcated oedema of all 4 limbs and haemorrhages on the visible mucosal membranes. she is depressed, tachycardic and tachypnoeic; there is some reluctance to move. Routine blood work shows elevated white cell counts, low red blood cells counts and hyperfibrinogenaemia.

    guttural pouch empyema
  • A 17yr old grey gelding undergoes endoscopy for suspected gastric ulcers. No gastric ulcers are found – hyperpigmentation is noted in the guttural pouches. what is the likely diagnosis?

    guttural pouch tympany
  • An equine foetus is ready to be delivered, what is the normal position:
    Anterior presentation, dorsosacral position with the front limbs extended
  • A 4-day old foal is presented for examination. He appeared normal at birth and his navel was treated appropriately but over the last 24 hours the stud owners have become concerned due to his reluctance to suck and increased time spent in recumbency. On clinical examination you identify pyrexia, prolonged skin tent and congested mucous membranes. You decide to take a blood sample and identify high fibrinogen, high serum amyloid A, low IgG and hypoglycaemia. What is the most likely diagnosis and underlying aetiology?
    septicaemia due to failure of passive transfer.
  • Synovitis can manifest in the tibiotarsal joint even in the absence of an underlying disease, and this occurrence is frequently observed in sport horses and Western performance horses engaged in active work. What is another name for chronic synovitis?
    Bog spavin
  • You’re an equine vet. A 16-year-old grey Thoroughbred gelding is presented for investigation of chronic weight loss and recent onset of respiratory difficulty alongside a lesion that the owner has seen on the face. The horse had recently developed depression, inappetence, pyrexia and pectoral oedema. The owner states the lesion has been present on the head for about two years. What is the most likely diagnosis? 
    melanoma

    Sycamore 
  • how do you treat EIPH in racehorses?
    a loop diuretic e.g., furosemide (this is not legal before a race)
  • An 18-month-old TB colt is presented to you with neurological signs. On closer examination, you discover there is symmetrical ataxia and weakness, with the hindlimbs affected more severely than the forelimbs. 
    Taking into account the signalment and clinical exam findings, what is the most likely diagnosis?
     cervical vertebral instability due to developmental orthopaedic disease.
  • A 4-year-old mare named Luna was presented. Luna's owner had noticed that she had not shown signs of oestrus for an unusually extended period, approximately five months after her last heat cycle. Luna appears normal and has had multiple and normal live births in the past. Concerned about this prolonged dioestrus, Luna's owner sought further evaluation. Ultrasound does not show pregnancy and rectal examination reveals follicles on the left ovaries but you note that they both feel roughly the same consistency and in size.  What is the most likely diagnosis?
    Persistent corpus luteum
  • Sepsis is a prevalent condition in foals, primarily occurring within the neonatal period (usually within the first 10-14 days of life). What is the most common isolate cultured from foals with neonatal sepsis?

  • 9yo QH, Duke presented with severe lameness and a hx of grain overload. he consumed a large amount of grain, and shortly afterwards, he became reluctant to move and displayed an abnormal posture. on CE he had an inc temp, a hard pulse in the digital arteries and he appeared in pain,(unwilling to move + hesitant gait). Tn abaxial sesamoid nerve block was performed on his forelimb digits to which effect the horse had a better range of movement and appeared much improved.

  • 6yo mare, Bella was brought in due to aggressive behaviours. she has a hx of stallion-like behaviours, including mounting other mares and displaying excessive "social animation" towards other horses in her paddock. on CE she has developed a cresty neck and noticeable weight gain.  the aggression has escalated, and she is frequently observed biting and kicking not only towards other horses but also towards people. what is the medical cause of this behaviour?
    granulosa cell tumour
