DL: Renal Case Studies (3 Cases) Flashcards
How would a bleed into the gut present clin path?
^^^ urea > ^ creatinine
v protein
What normal variation does PCV TP show?
Young dogs ^PCV v TP
Old dogs vPCV ^ TP
Tx congenital renal dysplasia?
No tx (lack of kidney tissue) PTS
What is hypercalcaemia of ,malignancy most commonly seen with?
- lymphosarcoma
- anal sac carnicoma
Define hyposthenuria, isisthenuria and hypersthenuria. When are these appropriate?
Hyposthenuria
- anything is appropriate unless azotaemic*
- if azotaemic should be >1.035
What tx should lymphoid malignancy respond to a single shot of (not necessarily cure but see response)
L-asparaginase
What does a low Ph with ^ Ca allow you to r/o
Structural kidney disease ( expect ^Ph)
Are animals sick with 1* hyperPT?
NO
Does hyper Ca cause depressed, tucked up appearance?
NO
What can large bowel D+ be refined into?
1* casues
- 2* VERY RARE large bowel
What type of pathology does meleana alone suggest?
1* GIT
- 1* and 2* expect other signs
What shoudl the Ca P product be?
Px Vit D toxicity
Not 100% sucess rate with tx
What can altered gut motility predispose to?
Intussecption
Can acidosis be dx by urine?
No
Causes acidosis
- urea and byproducts acidic
- anaemia -> anaerobic respiration -> acidifying
Should serum PTH be normal with ^ Ca?
NO should be low belwo ref range
What is the desmopressin response test used for? Is this reliable?
- central v nephrogenic DI
- can be positive even with 1* PD so always water deprive first
- can take a long time before dehydration sets in
How soon after administration should you see a response with desmopressin?
2-12hrs
Tx central DI? Cost?
Desmpressin eye drops ~ £25/month
Is the water deprivation test a safe test?
Risky
- if do have central DI will dehydrate very rapidly
- can die overnight
- must lose 5% BW to prove dehydration (or measure TP/PCV/Na/urea etc.)
How can hyperadrenocorticism be ruled out in some patients before doing any work up?
If they have pruritis cannot be HAC as would tx their own skin condition!
