|Endocrine means that a hormone is secreted _____. |Anterior & Posterior Lobe |
|Hormones act at a ____ level to affect gene expression. |Anterior Lobe |
|The pituitary gland is made up of what 2 parts? |Posterior Lobe |
|Which lobe gets VENOUS blood supply? |B/c venous supply has significantly lower pressure (compared to arterial). This |
|Which lobe gets ARTERIAL blood supply? |relatively low blood pressure supplying the anterior lobe makes that lobe vulnerable |
|Why do we care about the blood supply to the different lobes of the pituitary gland? |to ischemic injury (if BP drops a lot, the anterior lobe will receive much less |
|*KNOW* |blood, thus less oxygen, thus ischemic injury) |
|What does anterior lobe of the pituitary secrete? |GH (growth hormone), Prolactin, FSH (follicle stimulating hormone), LH (luteinizing |
|Posterior Lobe? |hormone), ACTH, TSH (thyroid stimulating hormone), MSH (melanocyte stimulating |

|Describe GOUT: |2 – 7 mg/dL |
|Normal range for uric acid? *KNOW* |> 7 – 7.5 mg/dL |
|Uric acid levels of ____ = GOUT. *KNOW* |~↑ uric acid (↑ protein intake, ↓ elimination, etc…) ~Being Male |
|Risk factors? (7) |~Age (men >30, women > 55) ~↑ |
|T or F? Most cases of GOUT are caused by underexcretion of uric acid. |SCr/BUN ~HTN|
|Define Underexcretion. *KNOW* |~↑ wt |
|How could we tell if pt was overproducing uric acid, causing their GOUT? *KNOW* |~↑ alcohol intake (beer, not wine) |
| |True! |
| |< 300 mg/24hrs |
| |If urate excretion > 1000 mg/24hrs |
|What is an Acute Gouty Attack? |Rapid onset of pain, swelling, and inflammation |
|What drugs can induce an attack? |~Losartan |
|What is “peudogout”? |~Phenofibrate |
| |~Amlodipine *they ↓ uric acid levels quickly, which may INDUCE an attack ( |
| |Gout-like presentation, but w/o elevated uric acid levels. The symptoms are from |
| |accumulation of calcium pyrophosphatate dihyrate or calcium Hydroxyapatite crystals. |
|Treatment: |NSAIDS (any NSAID is fine) |
| |Steroids |
|1st line DOC? |Colchicine |
|2nd line, if the NSAIDs are contraindicated? |Max Dose! (continue for 24hr after resolution of attack) |
|3rd line. If NSAIDs & Steroids are contraindicated? |If NSAID is contraindicated OR if NSAIDs fail |
|What dose of NSAID is appropriate for management of acute gouty attack? |Triamcinolone (intra-articular injection) & Prednisone |
|When would you use Corticosteroids to treat an acute attack? |# of joints affected ( one = triamcinolone (once) |
|Name the available corticosteroids for treatment of acute gout attacks: (2) |Multiple joints = prednisone (over 2 wks) |
|So you are gonna use a corticosteroid, but can’t decide which one. What will help you|8.) < 6 mg/dL |
|make the decision? | |
|What is the GOAL uric acid level? *KNOW* | |
|Prophylaxis: |Colchicine |
| |DON’T Prophylax if 1st attack: ~mild, |
|Which drug is the best option for prophylaxis? |responded to tx ~Sr urate mildly|
|How can you decide if a pt requires prophylaxis? |elevated ~urinary excretion < 1000 |
| |mg/24hrs DO Prophylax if 1st attack: |
| |(Severe (Complicated|
| |course of uric acid lithiasis (Sr urate >10 |
| |(Urinary urate excretion > 1000 mg/24hrs (Frequent attacks (>2/year) |
|Prophylaxis cont… |True!! (maintenance dose = 0.6 – 1.2 mg BID) |
| |CrCl < 50 mL/min *KNOW* |
|T or F? Colchicine is the DOC for prophylaxis of gouty attacks. |False!! It can be d/c’d if Sr urate is normal & pt is symptom free for 1 year ( |
|CANNOT prophylax w/ colchicine if ____. |Uricosurics ( Probenecid & Sulfinpyrazone (note: the |
|T or F? Once we decide to prophylax with colchicine, a pt will take it the rest of |uricosurics only help if problem if underexcretion) Xanthine Oxidase Inhibitor|
|their lives. |( Allopurinol |
|List the UALA’s: (3) |If pt is 7 – 7.5 |
|Uric acid levels which signal GOUT. |> 1000 |
|I excrete ___mg/24hrs of urate, so I must have overproduction problem. |< 300 |
|I excrete ___mg/24hrs of urate, so I must have an underexcretion problem. |Only 1 joint affected ; more than 1 joint affected |
|If giving steroids, give triamcinolone intra-articularly once if ____. Give |> 10 |
|prednisone over 2 weeks. if ____. |Allopurinol |
|Always prophylax if 1st attack had uric acid levels of ____ |Colchicine OR Uricosurics (Sulfinpyrazone or Probenacid). |
|Use ___ as prophylaxis if pt has hx of kidney stones. |Allopurinol |
