Q

All of the Above

*Azotemia can be Prerenal, Renal or Post Renal

In this patient all the differentials are a potential cause because:

If you have Induced Pu/Pd from Cushings, as soon as a Cushings dog becomes Dehydrated they will probably develop Pre-Renal Azotemia

If the Patient is on Furosemide or Phenobarbitone, Induced Primary Polydypsia will cause Renal Medullary Washout and these animals will not be able to concentrate their Urine

Review Card: IRIS staging for Chronic Kidney Disease

Stage I: Non Azotemic Kidney Damage

Stage II: As soon as the Patient Becomes Azotemic

Goals of Managment:

Stage I: Identify Primary Disease and Start Specific Therapy to Eliminate Disease if Possible

Stage II and III: Retroprotective Therapy to Slow Progression

Late Stage III and IV: Symptomatic Therapy

A

Proteinuria: Have to show that the Urine Protein remains elevated (Above 0.5) for an Interval Longer than Two weeks

Need to Know: Cut off for a Canine Proteinuric sample and Feline Proteinuric Sample:

Review Card: Types of Ulcerative Keratitis

A

Review Card: Healing of Superficial Stromal Ulcer

1. Within 30 Minutes to a Few Hours, White Blood Cells will come in and attempt to Fill the Defect

2. Then Keratocytes (Cells of the Cornea) Transform into Fibroblasts

3. The WBC’s have Collagenases that come in and Break up some of the Collagen so the Cornea can be Restructured. If the Collagenase Activity is Excessive results in Melting Ulcer

4. Epithelial Cells fill the Defect and Fibroblasts lay down Collagen to Restore Stromal Defect

A

Applantation (Tonopen, Accupen)- Detects how much Force is Needed to Flatten a Predetermined area of Cornea

Rebound (TonoVet)- Calculates IOP Based on the acceleration and deceleration of a Probe to and From the Corneal Surface

Q

Treatment in Cases of Recurrent Lower Urinary Tract Infections

A

Extended Antibiotic Therapy: 4-6 Weeks

Prophylactic Therapy: 6 Months (Nitrofurantoin)

*Prophylactic Therapy: Once you have steralized the Infection with 4-6 Weeks of Antibiotic Therapy, you then choose the Drug that the Bacteria is Sensitive too and Dose it Once Daily at 30-50% of Original Dose

*Prophylactic Therapy is Administered at Bedtime so that the Antibiotic will accumulate in the bladder over night
