Lead poisoning - diagnosis
history of ingestion
Radiographs
Blood lead levels
Lead poisoning - radiology
Lead Posining - Treatment
Midazolam - control seizures
Supportive - fluids, feeding
Chelation - calcium EDTA, D-penicillamine
GI - lubricatns and laxatives
Liver disease
Multiple Etiologies
Acute: infectious - chlamydia, toxins
Non-infectious: Hepatic lipidosis, hepatic fibrosis, iron storage disease, neoplasia
Hepatic Disease - Clinical signs
“Sick bird” symptoms
feather discoloration
beak and nail overgrowth
+/- palpable hepatic enlargement
Biliverdinuria
Normal Droppings
Urates: should be well formed and be white. Any changes to color or texture is an alert to a problem
Urine: should be clear and watery as shown. Color changes and amount can be an alert to a problem
Feces: should be green or brown. Diet can change the color of the feces, so if you notice a change compare to what was eaten
Biliverdinuria = green discoloration
Liver Disease - Diagnosis
History
Clinical exam
Clinical pathology; AST< CK, Bile acids
Radiographs - hepatic silhouette
Ultrasound + liver aspiration
Endoscopy and liver biopsy
Chlamydophila testing
Coelomic Distention
Due to effusion or hepatomegaly
Coelomic Effusion Radiology
Generalized loss of detail
Renal Disease
Any: infection, neoplasia, toxins
Clinical Signs: Non-Specific, +/- polyuria, coelomic distension, Lameness
Renal Disease
Clinical Pathology - increase Uric Acid
Radiology - renal enlargement
Edoscopy and Renal Biopsy
Renal disease
Treatment
underlying cause; supportive care
