(remember Rovsing sign, Obturator sign, psoas sign)

how do we diagnose acute cholecystitis?
U/S
HIDA (gold std) - when u/s is inconclusive CT scan (alternative, more sensitive for perf, abscess, pancreatitis)
LABS: alk phos, GGT (gamma-glutamyl transferase), conj bilirubin
(SmartyPance)

how do we treat diarrhea (4 things)?
four parts:
1 - fluid (this is a mainstay of management, oral is best!)

(do NOT give these to pts w/ invasive diarrhea)
4 - antiemetics
(PPP)

Diagnosis: Patients with self-limiting or mild symptoms do not automatically require further workup
(SmartyPance)
how do we diagnose those with atypical or long-standing heartburn symptoms?
diagnostic testing to confirm the diagnosis and to rule out complications of GERD
(??? this is a lame question - research it and improve it!)
(PPP)
how do we diagnose GERD?
clinically, based on hx
or
24-ambulatory pH monitoring (this is the gold std if confirmation is needed)
you CAN do esophageal manometry as well, check for decreased LES pressure
(PPP)
how do we diagnose GERD with persistent symptoms or alarm symptoms?
endoscopy - first line diagnostic test if persistent symptoms or complications of GERD is suspected
(i.e. alarm symptoms, malignancy, symptoms >5-10 years)
(PPP)
how do we treat GERD?
lifestyle modifications
- lift head of bed - don't eat right before bed - avoid foods that delay gastric emptying - stop smoking and drinking - lose wt
“Stage 2”: antacids and H2 receptor antagonists
