test 2 Flashcards
Stomatitis
inflammation around the edges of the mouth
Angular stomatitis
Inflammation in the corners of the mouth (edentulous-people with no teeth)
Aphthous stomatitis
canker sore
Ankyloglossia
tongue tied.
Leukoplakia
white plaque (pre-cancerous lesions) that don’t scrape away.
Koplik’s spots:
pearly white lesions that appear before the onset of measles
Candidiasis
thrush, common in people who are immunocompromised or on antibiotics
Palatoschisis
cleft pallet
Dental caries:
cavities
Gingivitis
inflammation of the gums. The gums with recede. (higher risk for cardiac problems)
Malocclusion
Malocclusion
Periodontal disease:
severe retraction of the gums. (higher risk for cardiac problems)
Achalasia:
Lower end of esophagus doesn’t open up. Can lead to aspiration. May result from nerve damage or genetics.
Gastroesophageal Reflux (GERD):
lower esophageal sphincter doesn’t close. Can lead to Barrett’s esophagus esophageal cancer.
Esophageal sphincter:
symptoms narrowing of the esophagus.
Acute gastritis
Inflammation of the gastric mucosa. Caused by irritants. May be asymptomatic. May complain of dyspepsia. Usually just treat the symptoms.
Hiatal Hernia:
Congenital defect. Occurs as a result of a weakness at the diaphragm causing a portion of the stomach to form a pouch above the level of the diaphragm.
Peptic Ulcer Disease (PUD
Ulcers that can be in the stomach, esophagus or duodenum. Duodenum ulcers are caused by hypersecretion of gastric acid from activation of the vagus nerve. Therefore, ulcers can be caused by stress.
Sliding hiatal hernia:
slides up and down depending on whether or not the stomach is full. Can be surgically repaired.
Paraesophageal (strangulated) hernia:
does not slide, stays in the mediastinum and can be strangulated or become ischemic due to strangulation by the diaphragm.
Pyloric Stenosis:
Narrowing (stenosis) of the outlet of the stomach so that food cannot pass easily from it into the duodenum. Pyloric stenosis results in feeding problems and projectile vomiting in infants. Can be corrected with surgery.
Dumping syndrome:
• Happens in people who have had gastric bypass surgery. Normally, the stomach empties in a slow and controlled manner.
• In post bypass surgery part of the stomach is removed and gastric contents get quickly dumped into duodenum.
• 2 things happen.
1. duodenal contents are hyperosmolar which draws water into the colon resulting in diarrhea.
2. blood sugar drops (hypoglycemia). BS goes up initially because of all the sugar being absorbed into the blood stream. Pancreas sees BS increase and releases insulin, dropping BS. Initially get cramping and bloating. Cold, clammy, sweaty, tachycardia, a couple of hours after eating.
Gastroenteritis symptoms
- Acute inflammation of the mucosa of the stomach and small intestine.
- Nausea, vomiting, diarrhea, abdominal cramping, low grade fever
- Dehydration
Causes of Acute Gastroenteritis
Viral: Norovirus: Rotavirus
o Bacterial: Salmonella enteritidis; Staphylococcus aureus, Enterohemorrhagic E. coli (0157:H7), Clostridium botulinum Clostridium difficile,
o Protozoan: Giardia intestinalis
Evaluation Gastroenteritis
stool for C&S; viral studies, O & P
Norovirus
- Member of a group of Caliciviridae (Cal·i·ci·vi·ri·dae)
- Transmission: person to person by direct contact or contact with fecally contaminated objects. May infect others up to 2 days after diarrhea has stopped. Common on cruise ships.
Rotavirus
- Member of a group of reoviridae
* Transmission: fecal-oral route. Common in day cares.
Salmonellosis Transmission
• ingestion of food/water ; also via hands; humans may be asymptomatic carriers
poultry. Lives in the intestines of poultry.
feces of an infected animal.
reptiles and vegetables.
•
Salmonella will be destroyed
at high temperatures.
Once the salmonella gets into a person
it releases a toxin, that causes inflammation in the GI tract, resulting in diarrhea and vomiting.
Typhoid Fever
- Caused by Salmonella typhi
- Get’s into the GI tract from contaminated water or shellfish. Thrives in areas with a low pH (i.e. stomach).
- Peyer patches: Live in the colon and are linked to the lymphatics. Salmonella Typhi links to these and spreads to the lymphatics. They can also become inflamed and obstruct the bowel causing abdominal distension.
- If untreated by week 4, perforated bowel will kill the person
Staphylococcal Food Poisoning
- Pathogen: enterotoxin-producing strain of Staphylococcus aureus
- Reservoir: humans – skin, abscesses, nasal secretions
- Transmission: ingestion of S. aureus-contaminated food
- Can form toxins that inflame the GI tract.
- Comes from food, hand made sandwiches, creamy desserts, especially things made with mayonnaise.
- Food borne illnesses can also come from surfaces, such as cutting boards.
Enterohemorrhagic E. coli
- Pathogen: Escherichia coli 0157:H7
- Transmission: water and food contaminated by cattle manure; low infectious dose
- Caused by the run-off from farm lands (from animal poop). Common in hamburger, can also contaminate vegetables.
- E-coli naturally lives in the GI tract and prevents you from getting other GI infections.
- Bacteria gets into GI tract, releases toxins causing inflammation, causes disease. The toxins also affect the glomerulus of the kidneys. Arterioles running through the glomerulus become inflamed and get clogged up by platelets causing them to become occluded. RBC travelling through them, become damaged (hemolysis: damage to RBC). The individual becomes anemic and ends up with kidney failure. Clotting cascade gets set off, and the person begins to hemorrhage.
Listeriosis
- Pathogen: Listeria monocytogenes
- Lives everywhere. Ingest food after it’s been processed. Common in deli meats, don’t eat raw hotdogs. Can cause miscarriage in pregnant women. Can develop meningitis.
Botulism
- Pathogen: Clostridium botulinum
- Can be in canned food (forms in places where there’s no oxygen). Does not grow as well in sweet or acidic foods. Can thrive in things like carrots. Can also come from potatoes.
- Gets into the stomach and attacks the nervous system. Can cause blurred vision, paralysis, and die from respiratory failure.
C difficile associated diarrhea (CDAD)
- Pathogen: clostridium difficile
- Bad bacteria that takes over the good ones in the intestines. Like dandelion’s taking over a garden.
- Can lead to pseudomembranous colitis. Bowel becomes so inflamed it develops necrosis.
Giardiasis
• Parasite Giardia intestinalis o Giardia lamblia o Giardia duodenalis • Spread by o Animal to person o Person to person • AKA: Beaver fever • Cold temperatures put the parasite into a protective cyst. Once the cyst gets into the GI, the cysts break open and the trophozoites attach themselves to the colon and they multiply. The person sheds them through the feces, into the cold water, and they form cysts.
Staphylococcus comes primarily from
handmade sandwiches (mayonnaise) and cream filled desserts.
• Botulism comes from
home canning. Normally lives in soil and is anaerobic. Therefore, canned foods are excellent for them. The symptoms attack the nervous system, symptoms are neurologic, unlike the others that have GI symptoms.
C-Dif: nosocomial bacteria often contracted from
hospitals. Can lead to pseudomembranous colitis. Bowel becomes inflamed and develops areas of necrosis. Membrane forms over it that is old necrotic tissue. Inflamed piece of bowel that becomes necrotic (pseudo membrane).
Giardiasis: get it from
water. Commonly known as beaver fever.
Appendicitis • Clinical manifestations
: umbilical pain initially; pain over McBurney’s point
Appendicitis Complication:
perforation, peritonitis
Obstruction of appendiceal lumen results in
inflammation of appendix
Peritonitis
• The peritoneum keeps all our internal organs from floating around. It can become inflamed. It has a large surface area so absorbs toxins easily.
Peritonitis If it becomes infected
the person becomes septic and dies. If inflamed, causes less peristalsis in the bowel and can cause an obstruction.
• Causes nausea, vomiting, and a bunch of other very bad shit.
Intussusception
: One part of the bowel folds over another. Common in babies and they get a sudden onset of colicky pain and pass a stool that looks like red Jell-O. The red is from blood in the colon. It’s a surgical emergency. The bowel can become strangulated and ischemic.
Inguinal hernia
Loop of bowel slides down through the inguinal ring (weak spot in the abdominal wall from where the balls dropped down).
Volvulus
: A twist or kink in the bowel. Occurs when there is a weak spot.
Adhesions
Formed from scar tissue. Internal organs and pieces of bowel stick together.
Acute Mesenteric Arterial Insufficiency
• The mesenteric artery is the major feeder to the bowel. Inferior and superior branch. Sometimes a blood clot travels to the artery causing it to occlude and become necrotic. People with atrial fibrillation and prosthetic heart valves are at increased risk. Intense, extreme pain felt after eating due to the ischemic bowel.
• Ischemia damages the colon, by
by damaging the mucosa rendering it incapable of protecting itself. May have fever, blood diarrhea, and other complications. If not treated immediately can lead to rupture and peritonitis.
