Low MCV anemia
iron deficiency
thalassemia
high MCV anemia
b12 (pernicious)
folic acid
normocytic anemia
anemia of chronic disease
sickle cell
renal failure
normocytic
80-100
normochromic
32-36%
s/s of iron deficiency anemai
Pica
palpiation
pallor
low MCV, low MCHC, low serum ferritin, High TIBC
thalassemia
microcytic hypocrhomic genetically inherited
seen in mediterranean, African, Middle eastern , Indian and asian population
most familiar type of thalassemia
beta thalassemia
forms of beta thalassemia
thalassemia minor (adults) one gene
thalassemia major children two genes
elevated MCV, MCHC normal, decreased serum folate
folic acid deficiency
s/s folic acid deficiency
glossitis
fatigue
anorexia
aphthous ulcers
*no neuro s/s
mtg of folic acid deficiency
folate 1mg every day
folate foods
pt presents with glossitis, paresthesia, loss of fine motor control and postive babinski what do you suspect and management
b12 anemia (pernicious)
b12(cyanocobalamin) 100mg IM daily x1 week then monthly lifelong (front loaded-once a dayqweek then monthly)
most common anemia in elderly
anemia of chronic disease
MCV normal, MCHC normal, serum ferritin high, TIBC low
anemia of chronic disease
beta minor thalassemia is what gene wise
heterozygous - only one copy of gene
which pt would have decreased a or b Hgb chains ?
thalassemia
b1
thiamine
reduced ability to create blood clots caused by mutation in clotting factor VIII
von willebrand disease
mtg of von willebrand disease
desmopressin, recombinant von Hillebrand factors/factor VIII concentrate
acute leukemia in adults
acute myeloggenous leukemia (AML)
pancytopenia with blasts is hallmark of disease
acute lymphocytic leukemia (ALL)
most common leukemia in adults with lymphocytosisi
chronic lymphocytic leukemia (CLL)
what is hallmark of chronic myelogensous leukemia (CML)
philadelphia chromosome
what is required to confirm dx of leukemia
bone marrow aspiration
stage II lymphoma is what
more than one lymph node group involved; confined to one side of diaphragm
stage III lymphoma is what
lymph nodes or the spleen involved; occurs on both sides of diaphragm
which Hodgkins is usually advanced stage disease at dx
non-hodgkins lymphoma
what characteristic differs Hodgkins from non-hodgkins lymphoma
reed-stern berg cells
thrombocytopenia resulting from autoimmune destruction of plateltes
idiopathic thrombocytopenia purport (ITP)
mtg of ITP
(idiopathic thrombocytopenia purpora)
high dose corticosteroids
IV gamma globulin
PLT Transfusion <20000
Path of DIC
thrombin -> fibrinogen to fibrin -> fibrin clots in microcirculation
decrease fibrinogen,PT, PLT, factor V and VIII are reduced
activates fibrinolytic system which lyses fibrin clots into fibrin degradation products
hemorrhage results from anticoagulantnt activity of FDPs and depletion of coag factors
labs r/t DIC
PLT <150,000
Fibrinogen < 170
Decreased RBCs
increased fibrin degradation products >45
PT >19 seconds
PTT >42 seconds
