25
Dyspepsia and abdominal pain....
Gastritis PUD
26
how do you dx a spiral shaped bacillus gastritis?
This is HP. you use a urea breath test, because urea is from the break down of bacteria. you can also use fecal urea test or anigen testing for HP.
27
what are the most common cuases of gastritis
HP, NSAIDS, Pernicious Anemia, ETOH, Stress
28
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?
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
Is PUD associated with cancer?
Yes, gastric uclers and HP are highly associated with gastric ademonas
30
what is the treatment for PUD?
A 14 day dose of PPI, Clarithromycin and amox. then cont the patient on the PPO
31
how do you test for PUD?
Endoscopy looking for the ulcers, history of use of NSAIDS or ETOH or a urea breath test for HP
32
what is Zollinger Ellison syndrome?
A gastrin secreating tumor (Gastrinoma) causing hypergastremia which results in PUD
33
What is the most common locations of a gastrinoma?
Pancreas or duodeum
34
What are the clinical features of Zollinger Ellison Syndrome?
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
how do you test for a ZES?
A fasting Gastrin >150 Secretin test >200 and endoscopy
36
pt with dyspepsia, weight loss, iron def anemia over the age of 40
Gastric Adenocarcimoma.
37
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
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
Irritable bowel syndrome Treat reasurrance, high fiber diet, bulking agents, antispazmetics and antihiahreals.
39
Patient with colicky epigastric/ RUQ pain stead and increase in intensity, occurs often after high fat meals, N/V possibly right scapular pain... dx: tx:
Labs: Bilirubin levels will increase, leukocytosis US HIDA ERCP Treatment sxr ACUTE CHOLECYTITIS
40
what is the triad for acute chollangitis and how will the patient present?
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
how do you diagnose hepatitis?
Aminotrnsferase elevations are seen in each type of hepatitis. this indicae hepatic intercell damage.
42
Patients presents with Tenesumus, blood and pus filled diarrhea, and mild to no abdominal pain (if present in the LLQ) dx: test: treat
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
43
patient under the age of 40 presents with severe abdominal pain and bloody diarrhea. Dx: Test: Treat:
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
where is the GI affected: Crohns UC
Crohns: From mouth to anus mostly on the right side UC: starts at the rectum and move proximally (Left side
45
what is the presenting symptoms Crohns UC
Crohns: ABD pain, bloody diarrhea (under 40) UC: bloody and pus filled diarrhea.
46
Pt with inflamation of the SB with gluten containing foods?
Dx: Celiacs- | DX test: IgA antiendomysial and antitissue transglutamine blood test.
47

51
if a patient has a colonoscopy with an polyp, which is removed when should he receive his next colonsocpy?
In 3 years. every 3 years after adeoma is removed
52
what are the classical signs of Portal hypertention?
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
what are some lab test for portal hypertention?
Decreased Albumin, increased billirubin
54
what is the formula used on paracentesis of acities fluid to determine if its from portal hypertention or an inflamatroy sorce?
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
what is the patho of hepatic encephalopathy.
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
what is used to decrease ammonia levels in the blood?
lactulose
