Q

what are the most common cuases of gastritis

HP, NSAIDS, Pernicious Anemia, ETOH, Stress

28
Q

what is dyspepsia (belching, bloating) abdominal pain that is burning or gnawing that often radiates to the back and either weight gain or anorexia dt?

A

PUD.

The weight gain makes you think its a duodeum ulcer, which the pain improves with food

where anorexia would make you think a gastric ulcer where the pain is worse with food.

29
Q

Is PUD associated with cancer?

A

Yes, gastric uclers and HP are highly associated with gastric ademonas

30
Q

what is the treatment for PUD?

A

A 14 day dose of
PPI, Clarithromycin and amox.

then cont the patient on the PPO

31
Q

how do you test for PUD?

A

Endoscopy looking for the ulcers, history of use of NSAIDS or ETOH or a urea breath test for HP

32
Q

what is Zollinger Ellison syndrome?

A

A gastrin secreating tumor (Gastrinoma) causing hypergastremia which results in PUD

33
Q

What is the most common locations of a gastrinoma?

A

Pancreas or duodeum

34
Q

What are the clinical features of Zollinger Ellison Syndrome?

A

It is clinically identical to PUD ( dyspepsia, abdominal pain that radiates to the back) but it has associated secretory diarrhea which is improved with PPI or H2 use. it also has melina leading to anemia.

35
Q

how do you test for a ZES?

A

A fasting Gastrin >150
Secretin test >200
and endoscopy

36
Q

pt with dyspepsia, weight loss, iron def anemia over the age of 40

A

Gastric Adenocarcimoma.

37
Q

what is the patho of irritable bowel sydrome?

unknown, but they think it is a combination of altered motility hypersensitivity to intestinal distention and psychological distress

38
Q

Patient with pain that is worse with food and releved with defication, has a combination of constipation and diarrhea. normal lab test and stool sample, negative colonoscopy?

how do you treat this person

A

Irritable bowel syndrome

Treat reasurrance, high fiber diet, bulking agents, antispazmetics and antihiahreals.

39

US HIDA ERCP
Treatment sxr

ACUTE CHOLECYTITIS

40
Q

what is the triad for acute chollangitis and how will the patient present?

A

Triad: RUQ pain, Jaundice, Fever

This is a potentially deadly condition of common bile duct obstruction combinded with asendingi nfection of ecoli/enterococcus/ kelb

Treatment is ABX drain or sxr

41
Q

how do you diagnose hepatitis?

A

Aminotrnsferase elevations are seen in each type of hepatitis. this indicae hepatic intercell damage.

42
Q

Patients presents with Tenesumus, blood and pus filled diarrhea, and mild to no abdominal pain (if present in the LLQ)

dx:
test:
treat

A

Dx: UC
Colonoscopy/sigmoidoscopy

starts at the rectum and continues proximally

smoking is actually preventative in UC.
SXR is a curative
can use aminosalicylates and steriods

Test:
Treat:

A

Dx: Crohns

Colonoscopy

starts anywhere in the GI tract from the mouth to the anus, mainly on the right side.
Treatment:
Acute: Steriods NPO
Chronically: Diet (Elementary diet) Mesalamine, SMOKING cessation is critical to decrease the severity and quantity of attacks.

44
Q

where is the GI affected:
Crohns
UC

A

Crohns: From mouth to anus mostly on the right side

UC: starts at the rectum and move proximally (Left side

45
Q

what is the presenting symptoms
Crohns
UC

A

Crohns: ABD pain, bloody diarrhea (under 40)

UC: bloody and pus filled diarrhea.

46

Endoscopy

50
Q

what is the treatment for H. Pylori induced ulcer?

A

PPI, Amoxicillin, and clarithromycin

51
Q

if a patient has a colonoscopy with an polyp, which is removed when should he receive his next colonsocpy?

A

In 3 years. every 3 years after adeoma is removed

52
Q

what are the classical signs of Portal hypertention?

A

Think the liver is fibrotic, so the hepatic vein can not drain fluid proximally, what comes off the hepatic vein.
Slenomegaly, Hemorrhoids, testicular atrophy, acities, caput medusa, pulmar erythemia, and spider andiomas.

53
Q

what are some lab test for portal hypertention?

A

Decreased Albumin, increased billirubin

54
Q

what is the formula used on paracentesis of acities fluid to determine if its from portal hypertention or an inflamatroy sorce?

A

Serum albumin- Acities albumin

if greater 1.1 then its portal hypertention.

Inflammatory causes will have a ratio under 1.1 meaning the serum and acites fluid have similar amounts of albumin, this is because the vessels become leaky and cause protien to leak out into the acities fluid (pancreatitis, TB peritonitis, Hepatoma)

55
Q

what is the patho of hepatic encephalopathy.

A

ammonia comes from break down of protein, in a health individual the ammonia goes to the liver and is converted to urea. then the urea is excreted by the kidneys.

but when the liver is not working well (cirrhosis, the body builds up the levels of ammonia, ammonia is able to cross the blood brain barrier, causing hepatic encephalopathy which is AMS. Patient will also get a non-rthythmic flapping tremor called asterixis.

56
Q

what is used to decrease ammonia levels in the blood?

A

lactulose

what is the stool osmolarity formula and what can it tell you?

A

stool osmolarity- 2 (stool na+stool K)

an osmolar gap greater than 125 suggest the diarrhea is caused my osmotically active particles in the stool such as laxative, lactose intolerance or ingestion of sorbitol containing foods.
