BLUE BOX Flashcards
Knowing diseases and their mechanisms (28 cards)
Respiratory Acidosis
Hypoventilation leads to an increase in CO2 in the blood, shifting bicarb buffer system rxn to left an increasing H+, decreasing pH
Respiratory Alkalosis
Hyperventilation leads to decrease in CO2 and shifts bicarb buffer rxn to the right, causing a decrease in H+ and an increase in pH
Metabolic Acidosis
Losing HCO3- in the kidneys (vomiting, diarrhea)
Metabolic Alkalosis
Adding strong base to bicarb buffer system (EX: Drinking MOM)
Chelating Agents
Inhibit metal cofactors; EX: Treating lead poisoning with Ca-EDTA; converts to PB-EDTA (can be excreted)
Myocardial infarction
Elevated enzymatic activity in troponin, CK, AST and LDH (TEST FOR TROPONIN-MORE SPECIFIC)
Niemann Pick
Deficiency in alpha sphingomyelinase; buildup of sphingomyelin; hepatosplenomegaly; CHERRY RED DOT IN EYE
Hemotolytic Disease of Newborn
RH+ express Rh antibodies; if fetus is rh- and mom is rh+, mom will send antibodies to fetal RBCs [Erythroblastosis Fetalis]
Spur Cell Anemia
Elevated cholesterol in membrane; decreases fluidity; RBCs lyse when passing thru small capillaries (spleen)
Cystic Fibrosis
Mutation in CTFR gene, chloride buildup in airway epithelial cells (thicker mucous); Salty sweat (Cl-) exits sweat glands
Cystinuria
Defect in transport of AAs like cystine, arginine, lysine; Renal colic and cystine crystals in urine
Hartnup Disease
Defect in transporter for non-polar/neutral AAs; Pallegra like dermatosis, lack of muscle coordination
Cardiotonic Drugs
Inhibit Na+/K+ ATPase; Slowing of NCX (leads to increased intracellular calcium and stronger contraction of heart muscle)
Steatorrhea
Fat in stool; could be result of malfunctioning SI, blockage of bile duct, insufficient bile secretion
Chron’s Disease
Segmented parts of diseased intestines (commonly the distal ileum); Abd pain, diarrhea, skin lesions, flatulence
Thiamine (B1)
Deficiency from alcoholism; Wernickes and Korsakoff, beriberi (wet-cardiac failure, peripheral edema) and dry (muscle wasting, paralysis)
Riboflavin (B2)
Deficiency from poor dietary intake (Dairy); Magenta tongue, corneal neovascularization
Niacin (B3)
HARTNUP; Impaired AA absorption; 4 Ds [ dermatitis, diarrhea, dementia, death]
Pantothenic Acid
B5; deficiency from extreme starvation
Pyridoxine (B6)
Deficient in isoiazid therapy; sideroblastic anemia, convulsions, intertrigo
Biotin (B7)
Carboxylation enzymes (important); deficiency from consuming too many raw eggs ; get alopecia
Folic Acid (B9)
Important in methylation/transfer rxns; Deficient in pregnancy and spina bifida; causes anemia
Cobalmin (B12)
Deficiency from pernicious anemia, pancreatitis; megoblastic anemia, neuropathies, homocysteinemia
Ascorbate (C)
Important in collagen + dopamine synthesis; deficient when you don’t eat enough cuties or veggies; SCURVY (Pirates life); poor wound healing, easy bruising, increased bleeding
