Midterm 2 Digestive System Flashcards
Hematemesis
Vomiting blood
Dysphagia
Difficulty swallowing
Dysuria
Burning, tingling, or stinging of the urethra and meatus associated with voiding.
Hematochezia
Fresh rectal blood (e.g. hemorrhoids, colon/rectal bleeding)
Atresia in esophagus
interrupted esophagus (i. e. atresia = lack of lumen)
Atresia in intestines
Partial/complete obstruction, or loss of a portion of the lumen
Barrett’s esophagus
neoplasia
RF/E: chronic exposure to acid from the stomach
Sx: frequent, long bouts of heartburn, dysphagia, vomiting blood (hematemesis), retrosternal pain
What is the change in terms of esophageal cell transformation?
Stratified squamous epithelium to columnar epithelium (pre-cancerous)
What is cirrhosis
End stage liver disease
Chronic liver disease is characterized by a loss of normal liver structure and function. Irreversible and incurable (except liver transplant)
Clinical features of cirrhosis
fatigue, weight loss, jaundice, ascites (accumulation of fluid in the abdominal cavity), edema, purpura (when small blood vessels burst, causing blood to pool just under the skin) / spider nevi (collection of small, dilated arterioles (blood vessels) clustered very close to the surface of the skin) / facial telangiectasia (“spider veins”) are dilated or broken blood vessels located near the surface of the skin or mucous membranes.), splenomegaly (enlarged spleen)
Type 1 diabetes
insulin dependent; juvenile onset
- absolute deficiency of insulin production and secretion
- autoimmune reaction against beta-cells. fibrosis and hyalinization
- prone to ketoacidosis and metabolic derangements
Type 2 diabetes
non-insulin dependent; adult-onset
- cellular resistance to insulin
- normal beta cells
- not normally prone to ketoacidosis or metabolic problems
What is diabetes insipidus
A disease in which the secretion of or response to the pituitary hormone Vasopressin is impaired – resulting in the production of very large quantities of dilute urine, often w/ dehydration and insatiable thirst
What is diverticulosis
disease characterized by formation of diverticula (i.e. outpouchings of the intestinal wall)
Most commonly in the sigmoid colon
Sx: Usually asymptomatic, increased urge to defecate
What is pancreatic cancer
Adenocarcinoma (95% of the pancreatic tumors)
Px: incurable - nearly all pts die within 12-24 months of Dx. 5yr survival rate is less than 5%.
