Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
The most common cause of inadequate adrenal production is idiopathic adrenocortical atrophy. [7] All causes for hypoadrenocorticism are not yet known. The usual causes are genetic, often related to autoimmune disorders, where the body attacks and kill its own tissue ("immune mediated destruction"). [ 8 ]
Severe symptoms include confusion, muscle twitching, and bleeding in or around the brain. [ 1 ] [ 2 ] Normal serum sodium levels are 135–145 mmol/L (135–145 mEq/L ). [ 5 ] Hypernatremia is generally defined as a serum sodium level of more than 145 mmol/L. [ 3 ] Severe symptoms typically only occur when levels are above 160 mmol/L. [ 1 ]
The symptoms vary greatly, in part, because of the underlying or causing infection. While the inflammation can cause a number of effects such as those mentioned previously, the base infection could cause other symptoms that don't necessarily have to do with the ventriculitis, itself. One of the challenges doctors face in diagnosing ...
Naproxen (Aleve)* has a long half-life in dogs and can cause gastrointestinal irritation, anemia, melena (digested blood in feces), and vomiting. [175] Antifreeze* is very dangerous to dogs and causes central nervous system depression and acute kidney injury. Treatment needs to be within eight hours of ingestion to be successful. [174]
First signs of this immune dysregulation can show through lethargy and the reluctance to walk. Behavioral changes and an abnormal mentation might occur. [ 6 ] After a short amount of time vestibulo-cerebellar symptoms will rapidly progress, leaving the animal in a state of depressed consciousness having seizures , amaurosis and ataxia .
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
Autoimmune disease as a cause is controversial because some studies have supported the presence of antiretinal autoantibodies in dogs with SARDS, [6] [7] but others have failed to show a link. [8] Despite similar symptoms and blood test results to Cushing's disease, evaluation of dogs with SARDS did not reveal any tumors in the pituitary or ...
