Oral neoplasms(new growth) commonly occur on the 1.Floor of the oral cavity(mouth) 2.Tongue 3.Interior oral labia(lip)
Labial carcinoma is often associated with pipe and cigar smoking
Carcinomas of the buccae(cheeks), tongue, or palate(oral roof) are commonly associated with chewing tobacco or dipping(snuff)
A premalignant sign of an oral neoplasm(new growth) is leukoplakia (white patches that appear on the mucous membranes of the oral cavity
Dx of an oral neoplasm(new growth) is confirmed with a Bx(biopsy)
Oral neoplasms(new growth) respond well to surgery & radiation therapy
Signs & symptoms of an esophageal malignancy include 1.Dysphagia(difficult swallowing) 2.Vomiting 3.Halitosis(bad breath) 4.WT(weight) loss 5.Aphagia(inability to swallow)
Dx for an esophageal malignancy includes an UGI(Upper GastroIntestinal) AKA barium swallow
The Px(prognosis) for an esophageal malignancy is poor because metastasis(spread) usually occurs before detection
Esophagitis is an inflammation of the esophagus
Esophagitis is commonly caused by GERD(GastroEsophageal Reflux Disease)
GERD(GastroEsophageal Reflux Disease) is commonly caused by an incompetent cardiac sphincter(lower esophageal sphincter)
The incompetent cardiac sphincter(lower esophageal sphinclter) allows stomach contents to regurgitate(reflux/back flow) up the esophagus

A complication associated with PUD (Peptic Ulcer Disease) is ulcer perforation(rip or tear) and hemorrhage (rapid flow of blood)
Signs of perforation include 1.Extreme abdominal pain 2.Hematemesis(vomiting blood) 3.Melena(black, tarry, pungent/aromatic stools)
A complication of ulcer perforation is peritonitis(inflammation of the abdominal lining)

CD(Crohn's Disease) is a chronic, idiopathic(unknown autoimmune/attacking itself) IBD (inflammatory bowel disease)
CD (Crohn's Disease) runs in families
CD(Crohn's Disease) is usually diagnosed between the ages of 20 and 40

Each year _______ Americans die from colorectal malignancies 72,000
Deaths from colorectal malignancies can be decreased by 90% if Colonoscopies are routinely performed after age 50 or if there is a previous hx(history)of polyps
ACS (American Cancer Society) suggests the following at age 50 -Colonoscopy every 10 years -Sigmoidoscopy every 5 years -BaE(Barium Enema) every 5 years -Virtual colonoscopy every 5 years -If no access to these test, stool guaiac(Hemoccult) every year
A bowel obstruction is AKA ileus
An ileus caused by a reduction of peristaltic (bowel contraction) activity is called a paralytic ileus (stool blockage)
An ileus (bowel obstruction) caused by the bowel twisting on itself is called a volvulus (garden hose kinks)
An ileus caused when the intestine telescopes on itself is called intussusception (telescoped inside itself)
An ileus can also be caused by adhesions (tissue sticking together)

Symptoms of IBS(Irritable Bowel Syndrome) tend to worsen with poorly controlled stress
The difference between IBS(Irritable Bowel Syndrome) and other intestinal disorder is that no lesions are present on examination
IBS(Irritable Bowel Syndrome) is a disorder of motility(peristalsis) and intestinal wall muscle spasms(Adult colick)
Tx for IBS (Irritable Bowel Syndrome) includes >Increasing fiber in diet >Avoiding caffeine, fatty food, spicy foods, alcohol(ETOH), citrus, cabbage,lagumes(beans, peas) >Stress management >GI antipasmodies(Bentyl) >Antidiarrheals(Kaopectate) >Sedatives(Xanax)

Px for the HAV(hepatitis A virus) is good with no permanent liver damage & a lasting immunity
A vaccine (Havrix, Vaqta) is now available for immunization(inoculation) against the HAV(hepatitis A virus)
HBV (hepatitis B virus) can lead to chronic hepatitis & cirrhosis
Signs & symptoms of the HBV(hepatitis B virus) are similar to the HAV(Hepatitis A virus)
Signs & symptoms of the HBV(hepatitis B virus) can occur 2 to 6 months after exposure
Transmissions of the HBV(hepatitis B Virus) is the same as the HIV(Human Immunodeficiency Virus)
The HIV & HBV are transmitted 1.Parenterally(needle/IV) 2.Sexually 3.Perinatally(during gestation/pregnancy, parturition/birth & breast feeding
Parenteral transmission usually refers to needle sticks & exposure to certain body fluids
Potentially hazardous body fluids include >blood or anything with blood in it >Synovial(joint) fluid >Pleural(lung) fluid >CSF(CerebroSpinal Fluid) during a LP(Lumbar Puncture) >Peritoneal(abdominal) fluid >Amniotic fluid(water breaks) >Breast milk
Carriers of the HBV(hepatitis B Virus) can be asymptomatic(no symptoms)
Damage from the HBV can cause fulminating hepatitis where the patient can suddenly become comatose & die
A lasting immunity can be achieved for the HBV (hepatitis B Virus) by vaccination(Hepatovax, Engerix B, Recombivax HB) or contracting the disease and recovering completely
Some people will not completely recover from the HBV(hepatitis B virus) and will be carriers of the disease
Tx for the HBV(hepatitis B virus) includes antiviral therapy
Signs & symptoms of the HCV(Hepatitis C Virus) are similar to the HBV(hepatitis B virus)
The HCV(hepatitis C virus) is insidious(slow to develop)(most dangerous)
The incubation period for HCV(hepatitis C virus) may take up to 20-30 years to damage the liver significantly
70% of people with the HCV(hepatitis C virus) are asymptomatic(no symptoms)
80% of people with the HCV(hepatitis C virus) will develop cirrhosis(degeneration of the liver) and/or liver cancer
The HCV(hepatitis C virus) is the #1 reason for a person to need a liver transplant
The HCV(hepatitis C virus) is transmitted 1.Parenterally(needle sticks & certain body fluids) 2.Sexually 3.Perinatally(during gestation/pregnancy, parturition/birth) (NOT FOUND IN BREAST MILK)
Everyone should be tested for the HCV(hepatitis C virus) who received a blood transfusion before July 1992
Tx for the HCV(hepatitis C virus) includes 1.Antiviral therapy 2.Liver transplant
Hepatic(liver) malignancies(cancer) are usually secondary tumors that metastasize(spread) from the colon, rectum, stomach, pancreas, esophagus, lung and breast
Hepatocarcinoma is a primary malignancy commonly associated with alcohol(ETOH), HBV(hepatitis B virus) and HCV(hepatitis C virus)
Signs & Symptoms of a liver malignancy include WT(weight) loss, RUQ(Right Upper Quadrant) abdominal mass and pain
Dx of a liver malignancy is confirmed with an AFP(AlphaFeta-Protein) blood test and liver Bx(biopsy)
The Px for a liver malignancy is poor
Cholecystitis is an inflammation of the gall bladder
Cholecystitis is commonly caused by an obstruction due to cholelithiasis(gall stones) AKA biliary calculi(stones in the bile duct)
The biliary obstruction can lead to hepatic(liver) damage
Increased incidence of cholelithiasis includes 1.Postpartum(after birth) women 2.Use of BCPs(Birth Control Pills) 3.DM(diabetes mellitus) 4.Cirrhosis(chronic degeneration of the liver) 5.Pancreatitis(inflammation of the pancreas)

Tx for cholelithiasis includes 1.Laparoscopic cholecystectomy(excision of the gall bladder) before preforation(rip/tear) occurs 2.Laparoscopic cholelithectomy(excision of gall stones) if stones are present in the common bile duct
Pancreatitis is an inflammation of the pancreas
Pancreatitis is commonly associated with alcoholism in men and GB(gall bladder) disease in women
Pancreatitis can cause pancreatic enzymes to activate prematurely(enzymes activate while still in the pancreas)
These activated pancreatic enzymes will start to digest(dissolve) the pancreas
Pancreatic enzymes include 1.Trypsin 2.Chymotrypsin 3.Lipase 4.Amylase
High levels of these pancreatic enzymes will confirm the diagnosis of pancreatitis especially the enzyme amylase
Signs & symptoms of pancreatitis include 1.Severe abdominal pain 2.N&V(nausea & vomiting) 3.Jaundice(yellowing of skin/sclerae)
Pancreatitis can result in death
Risk factors for a pancreatic malignancy include 1.male gender 2.smoking 3.high protein & high fat diets 4.alcohol(ETOH) 5.DM(diabetes mellitus)
Signs & symptoms of a pancreatic malignancy include 1.severe abdominal pain 2.anorexia(loss of appetite) 3.WT (weight) loss 4.Clay-colored stools(grey) 5.Jaundice(yellowing of skin/sclerae)
Dx of pancreatic malignancy is confirmed with a CT(Computerized Tomography) or MRI(Magnetic Resonance Imaging) or PET (Positron Emission Tomography and Bx(biopsy)
The Px(prognosis) for a pancreatic malignancy is very poor due to early metastasis(spreading)
