Q

what causes zencker diverticulum

A

sphincter dysnfunction and dysmotility

17
Q

diagnosis and treatment of zencker diverticulum

A

dx: barium esophogram
tx: surgery- excision or cricopharyngeal myotomy

18
Q

how to improve steatorrhea in patients with chronic pancreatitis?

A

pancreatic enzyme supplementation

19
Q

acute pancreatitis treatment

A

resolves in 4-7 days

supportive care, IVF, analgesics

20
Q

elevated alk phosphatase and positive AMA. think…

A

primary biliary cholangitis (autoimmune)

21
Q

primary biliary cholangitis symptoms

A

pruritus, fatigue

jaundice, hepatomegaly, steatorrhea, xanthelasma

22
Q

primary biliary cholangitis treatment

A

ursodeoxycholic acid

  • decreases biliary injury by hydrophobic bile acids
  • increases biliary secretion
  • anti-inflammatory
23
Q

urinary outflow obstruction symtpoms

A

flank pain

low urinary output with periods of post-obstructive diuresis

–> potassium wasting –> weakness

24
Q

is there screening for bladder cancer?

A

no

25
Q

what is this: bladder pain, worse with filling, relief with voiding. frequency and urgency. also dyspareunia.

A

interstitial nephritis

26
Q

how does acyclovir cause crystal-induced acute kidney injury?

A

acyclovir excreted into urine but has low urine solubility –> precipitates –> renal obstruction

–> AKI within 24-48 hours

27
Q

symptoms of aut dom `polycystic kidney disease

A

intermittent flank pain and mass
hematuria
UTIs
nephrolithiasis

28
Q

workup of BPH

A
  1. UA and PSA
  2. if significant symptoms or risk factors, test Cr
  3. if Cr elevated, do renal US to r/o hydronephrosis
29
Q

most sensitive test for diabetic nephropathy

A

random urine for microalbumin/Cr ratio

30
Q

multiple peptic ulcers and diarrhea. think…

elective proctocolectomy

screen for upper GI tumors

37
Q

diarrhea, weight loss, and apthous ulcers. think…

A

Crohn’s

38
Q

how is BUN/Cr ratio increased in someone with upper GI bleed?

A

increased urea production (from Hgb breakdown)

increased urea absorption (from hypovolemia)

39
Q

can IBS diarrhea have mucous?

A

yes
