  1. 3. EPM organism
  2. 4. very common type of colic caused by diet change/upset (grain overload). CS - mild/sev pain +/- spasmodic
  3. 6. chronic vit E deficiency in adult horses causing weakness (low head carriage and high tail carriage), muscle atrophy, no ataxia
  4. 10. brainstem form of rabies - somnolence, dementia, dysphagia, ataxia
  5. 11. type of colon displacement where there is nephrosplenic entrapment - colon goes into deep space b/n left kidney/spleen and becomes gas distended
  6. 13. twist in SI causing strangulation at root of twist = colic
  7. 17. multiple different causes, most strangulate causing quick revitalization of tissue. CS - severe pain, gastric reflex, dilated/non motile loops of SI, abd fluid = serosang
  8. 23. respiratory disease but can mutate to EHV1, ataxia with paraparesis, urinary incontinence, loss of tail tone, dx with nasal PCR
  9. 25. treatment of EPM
  10. 27. Vit E deficiency and a genetic component cause severe neuroaxonal dystrophy in young horses causing symmetrical ataxia of all 4 limbs
  11. 33. common type of colic resulting from a backup of fecal matter, esp with dec water intake. CS - mild/intermittent colic, dec manure prod, palpable firm feed impaction on rectal
  12. 34. toxin that block Ach vesicle release at NMJ preventing electrical signals
  13. 35. cause of colic in younger horses, diet changes, parasites; most commonly ileocecal
Down
  1. 1. non-obstructive type of colic pain most frequently in stressed horses. Caused by prolonged time with empty stomach, NSAID use. treated with omeprazole
  2. 2. spinal cord form of rabies - progressive ascending paralysis
  3. 3. ascarids impaction: verminous arteritis aka thromboembolic colic where the parasite migrates to the cranial mesenteric a.
  4. 5. piece of SI entrapped through a rent in mesentery causing strangulation
  5. 7. caused by clostridium tetani through a wound causing a stiff/spastic gait, noise and light hyperesthesia, lock jaw, 3rd eyelid prolapse
  6. 8. aka sand colic, CS - mild/moderate intermittent pain found in horses where there is sandy soil fed insuff roughage/malnourished, arabians can get these with too much alfalfa
  7. 9. granulomatous perineuritis of peripheral n and CN, thought to be immune mediated causing hind end LMN signs, CN 3,5,7,8,9/10 deficits
  8. 12. type of colon displacement where the colon is between the cecum and right body wall
  9. 14. east coast virus maintained by wildlife, transmitted by mosquito, “sleeping sickness” head pressing, blind, circle, ataxia, recumbency, coma, seizes
  10. 15. disease from bite by infected wildlife causing self mutilation, dysphagia, 3 forms
  11. 16. equine roundworm that can cause colic after deworming, usual yin <1y
  12. 18. form of colic can happen at any ages where a portion of colon twist rapidly and becomes ischemic leading to necrosis. CS - severe pain, inc HR/shock, NO gastric reflux
  13. 19. non-GI cause of colic signs in pregnant mares later in gestation. tight band of broad ligament will be palpable on rectal. treated by rolling the mare around the fetus or sx
  14. 20. treatment for nephrosplenic entrapment to shrink spleen and decrease nephrosplenic space
  15. 21. opossums are DH, chronic with mild/vague signs, unilateral hind-end muscle atrophy
  16. 22. maintained by birds,transmitted by mosquito, leads to head, neck, and muscle fasiculations, ataxia, paraparesis and recumbency
  17. 24. compressive lesion, almost always cervical (C3-C7) in large, fast growing breeds (thorough, warmblood), 2 types (congenital, osteoarthritis)
  18. 26. cerebral form of rabies - odd/aggressive behavior, self-mutilation, vocalization
  19. 28. non-GI cause of colic signs predominately in stallions and geldings fed alfalfa or high protein diets. Ca Carbonate stones. require emergency sx removal
  20. 29. diagnostic finding of rabies
  21. 30. cause of colic that can be inguinal, umbilical, incisional
  22. 31. disease from eating silage, poorly stored forage, round hay bales causing symmetrical flaccid paralysis and gradual progressive weakness, dysphagia
  23. 32. cause of colic where a mass with a stalk twists around SI causing strangulation, affects older 20+
