A

High risk for cancer

20
Q

A

> 4-6 mg/ml

21
Q

(T/F) PSA (prostate specific antigen) is higher with age

A

True

22
Q

The more PSA bound to ______________, the higher the risk of cancer.

A

alpha-1-antichymotrypsin (inflammatory protein)

23
Q

How many American adults have chronic kidney disease?

A

26 Million

24
Q

How many American adults are on dialysis?

A

½ million

25
Q

What are 3 main causes of Chronic Renal disease?

A
  1. Diabetes
  2. Hypertension
  3. Chronic glomerulonephritis
26
Q

What is the most common primary glomerulonephritis?

A

IgA nephropathy—triggered by a viral infection

27
Q

5 things CRD patients can have:

A
  1. Platelet dysfunctions (bleeding)
  2. Gingival hyperplasia
  3. bone abnormalities (slow bone healing after oral surgery)
  4. Premature bone loss (osteoporosis)
  5. Infectious complications (due to immunosuppression)
28
Q

4 common symptoms of CRD

A
  1. Heavy proteinuria (excessive protein in urine indicates renal cell death)
  2. Hematuria
  3. Inflammatory injury to kidneys (e.g., immune deposits in glomeruli block normal blood filtration and reabsorption)
  4. Glomeruli scarring and damaged functioning-could be sclerotic types
29
Q

What are 4 common treatments (and analgesic) for small (<1 cm) kidney stones?

A
  1. Drink considerable water
  2. Dietary changes
  3. OTC analgesics (ibuprofen, Naprosyn)
  4. Tamusolin (Flomax)—relaxes ureter muscle (often have spasm due to irritation of the stone)
30
Q

What are 3 treatments (and analgesic) for larger kidney stones?

A
  1. Lithotripsy (shock wave treatment)-break up stones
  2. Surgical removal
  3. Opioid analgesics for pain
31
Q

What is the most common type of kidney stone? What percentage?

A

Calcium/oxylate excess in urine (~80% of stones)

32
Q

What type of kidney stone is often associated with urinary infections? What Percentage?

A

Struvite (~10% of stones)-magnesium ammonium phosphate crystals

33
Q

What is the only treatment for struvite kidney stones?

A

Acidify urine

34
Q

Which type of kidney stone is often associated with gout?

A

Uric acid

35
Q

In treatment of kidney stones, what is Hydrochlorothiazide for?

A

Thiazide diuretic—reduces calcium in urine

36
Q

In treatment of kidney stones, what is Sodium bicarbonate for?

A

Alkalinizes urine

37
Q

In treatment of kidney stones, what is Allopurinol for?

A

E. Coli

39
Q

What are 3 common treatments for UTIs?

A
  1. Trimethoprim-sulfamethoxazole
  2. Amoxicillin + clavulanic acid (resistant bacteria a problem)
  3. Ciprofloxacin (expensive)
40
