Blood Pathology Flashcards
transplant rejection requires _____
lifelong anti rejection drugs
includes any kind of lymphoma except Hodgkins
either B cell or T cell neoplasms that may originate from any lymphoid tissue but most commonly in lymph nodes
non-hodgkins lymphoma
s/s of flu like symptoms, fever sore throat, fatigue. can have enlarged spleen
mono
intrinsic pathway
exposure to collagen
most common form of leukemia in children
acute
compromise to hematopoiesis, bone marrow suppression, enhanced RBC destruction, chronic disease
Nromocytic nromochromic
goal of this disease is treatment to suppress viral load and increase CD4+ count
AIDs
decreased total RBC mass
leads to decreased oxygen carrying capacity
s/s include headache fatigue, dyspnea, poor exercise tolerance, allow, syncope, tachycardia, evaluated by assessing H/h
anemia
anemias classified based on morphology
_____ -> volume (size) of RBC, micro, norm, macro
_____ -> hemoglobin amount, hypo, normo , hyper
cystic
chromic
complication of diseases that accelerates clotting, caused by disorders that produce necrosis, infection, neoplastic disease and other conditions that include cardiac arrest, cirrhosis, shock
excessive bleeding and excessive clotting, high fatality
DIC
hallmark sign is formation of granulomas
chronic inflammation
body can’t differentiate between self and non self antigens
autoimmune
hereditary bleeding disorder characterized by prolonged bleeding time
can range from mild and asymptomatic to severe
autosomal dominant trait but acquired from identified in pts with cancer
results from deficiency of Von Willebrands factor, which stabilizes clotting factor VII that is needed for proper platelet function
Von Willebrand disease
bedrock of healing process, largely made up of connective tissue, proliferative phase
granulation tissue
most common type of leukemia in children, but can affect adults over 65
include precursor B or T lymphoblasts
typical characterized by structural and numerical changes in the chromosomes within the leukemic cells (translocations, d deletions, hyperploidy, polyploidy) that alter the ability to regulate normal hematopoiesis
Acute lymphoblastic leukemia (ALL)
Genetic anemias
Sickle cell: genetic disorder where genetic change in beta-globing that causes sickling
thalassemia- genetic disorders causing defect in global chains that comprise hemoglobin
mainly adutlts, maybe small number of children
characterized by excessive proliferation of marrow granulocytes, erythroid precursors, and megakaryocytes
associated with the Philadelphia chromosome
begins in chronic phase progressing to accelerated phase ultimately entering a blast crisis phase which is terminal
treated with tyrosine kinase inhibitor drugs improving survival rates to greater than 95%
Chronic myelogenous leukemia
wound edges with close approximations, edges sealed by cblood clot or sutures
first intention
involved pluripotent myeloid stem cells in bone marrow, interferes with maturation of all blood cells including granulocytes, erythrocytes, and thrombocytes
myelogenous leukemia
- acute myelogenous leukemia
- chronic myelogenous leukemia
specialized form of lymphoma
characterized by the orderly spread of disease from one lymph node group to another and by development of systemic symptoms with advanced dieases
Reed-Sternberg cells
2 peaks of incidence- 1st in young adulthood and 2nd - 55+
more treatable
hodgkins lymphoma
competes with vitamin K (vitamin k is antidote)
Warfarin (Coumadin)
some compromises to wound healing
malnutrition, infection, some drugs (steroids, NSAIDS) diabetes, hypoxemia
immature lymphocytes and their progenitors that originate in the bone marrow but infiltrate the spleen, lymph nodes, CNS, and other tissues
lymphocytic leukemia
- acute lymphoblastic
- chronic lymphocytic
build up of relatively mature but abnormal white blood cells and generally takes months or years to progress
chronic leukemia
