Q

What are the three types of vWD?

A

Type I - all mulitmers are present but a a decreased conc. => variable severity of bleeding (DOBERMANS)

Type II - Qualitative abnormalities in vWF structure and function, severe and uncommon

Type III - Absence of all vWF mutlimers

Q

Diagnotics for vWD?

A

Measure levels of vWF:Afg, vWF levels will be decreased by clots in the sample and haemolysis
ELISA
Genetic test for carriers

Q

Treatment for vWD?

A

Transfusion to supply vWF
Cryoprecipitate - concentration of vWF is 5-10x greater than plasma
Whole blood if animal is anaemic
Desmopressin as a pre-operative prophylactic as it causes vWF release

23
Q

Causes of haemothorax in the horse?

A
Trauma
Pulmonary haemorrhage
Necrotising penumonia
Ruptured pulmonary vessel
DIC/coag
Neoplasia
24
Q

Causes of haematuria in the horse?

A
Pyelonephritis
Cystitis/urolithiasis
Idiopathic renal haematuria 
Urethral rent 
Neoplasia
25
Haemoabdomen causes in horses?
Trauma Ruptured mesenteric vessel Uterine artery rupture Neoplasia
26
Gastrointestinal causes of bleeding in horses?
Parasitism Neoplasia Ulceration Granulomatous enteritis
27
Pathogenesis of EIPH in horses?
Strenuous exercise => pulomary haemorrhage => local inflammation => further increase to regional resistence pressures
28
Diagnosis of EIPH?
Endoscopy and BAL (haemocidrin in macrophages)
29
Treatment of EIPH?
Minimise dust environment Change exercise regime Furosemide
30
What is PEH?
Progressive ethmodial haematoma - an enlarging non-neoplastic mass lesion in ethmoid turbinates causing spontaneous epistaxis
31
Tx for PEH?
Excision via frontal bone flap or injection of formalin
32
Causes of epistaxis in the horse?
``` Fungal sinusitis PEH Guttral pouch mycosis Nasal aspergillosis Coagulatopathy/DIC Sinusitis Sinus neoplasia ```
33
DDx for the bleeding farm animal
``` Abomasal ulceration Babesiosis SARA Enzootic haemturia BVD Anthrax Haemorrhagic anaemia - Haemonchosis - Fasciolosis - Pyelonephritis - Caudual vena cava syndrome ```
34
Causes of abomasal ulceration in ruminants
Sand, DA, stress
35
CS of abomasal bleeding in ruminants?
Acute: animal may die within 24hrs of becoming anorexia, decreased milk yield, increased HR, ruminal stasis, blood in faeces Chronic: follows subacute haemorrhagic incident which lasts around 5 days with scant black tarry faeces, anorexia, reduced milk yield
36
Diagnosis of abomasal ulceration in ruminants?
Clinical signs, history, and presence of blood in faeces
37
Tx of abomasal ulceration in ruminants?
Acute cases - fluid therapy and blood transfusion attempted with low success rate Chronic cases: oral kaolin and pectin together with magnesium oxide (acts as antacid) - improvement transient
38
CS of babesia in farm animals?
Sudden onset dullness, anorexia, reduced milk yield, red water, fever, ruminal stasis, anaemia, pipe stream d+
39
Diagnosis of babesia in farm animals?

40
Treatment of babesia in farm animals?
