The role of phosphorus in feline chronic renal disease (Proceedings)
November 1, 2010

Less than 1% of the total body phosphorus is in the plasma with 1/3 of this as inorganic phosphate ions, most of which are unbound. Laboratory analysis of serum phosphorus measures all forms of H3PO4 (H3PO4, H2PO4, HPO4) referred to as inorganic phosphate. Serum phosphate levels are higher in serum than plasma due to the clotting process that releases phosphorus from cells and platelets.

Feline idiopathic hypercalcemia (Proceedings)
November 1, 2010

Calcium in circulation occurs in three forms: calcium bound to proteins (approximately 40%), calcium complexed to various anions such as citrate and phosphate (8%), and ionized calcium (iCa, approximately 52%. The latter is the biologically active form of calcium and clinically-relevant hypercalcemia only exists when the ionized fraction of calcium is elevated.

Acute intrinsic renal failure (AIRF) - causes and prevention (Proceedings)
August 1, 2009

Acute renal failure is a clinical syndrome characterized by an abrupt increase of serum creatinine and blood urea nitrogen (BUN) concentrations to above normal (azotemia).

Problem urinary tract infections (Proceedings)
August 1, 2009

Ascent of bacteria is the most common origin of bacteria in UTI.

Prolonging life and kidney function (Proceedings)
August 1, 2009

CRF is clinically characterized in dogs and cats by the development of variably progressive irreversible intrarenal lesions and loss of renal functions.

Urinary incontinence in dogs -- diagnosis and treatment (Proceedings)
August 1, 2009

Primary sphincter mechanism incompetence (idiopathic incontinence, hormone-responsive incontinence) is the most common and important acquired cause of incontinence in dogs.

Management of male cats with urethral obstruction (Proceedings)
August 1, 2009

Urethral plugs are the most common cause of obstruction in male cats.

Non-obstructive idiopathic/interstitial cystitis in cats: Thinking outside the (litter) box (Proceedings)
August 1, 2009

A diagnosis of interstitial cystitis in people and cats requires identification of the presence of characteristic (although non-specific) sub-mucosal petechial hemorrhages--referred to as glomerulations--by cystoscopy, though the diagnostic value of this criterion is under debate.

Hypercalcemia in dogs and cats – How much should I react? (Proceedings)
August 1, 2009

An increased serum calcium is typically first noted when total calcium (tCa) is measured as part of a biochemistry profile.
