Hemolytic anemia: Sickle Cell Hemolytic anemia: Sickle Cell anemia (SSA)anemia (SSA)
Congenital hemolytic anemia resulting from a Congenital hemolytic anemia resulting from a defective Hb molecule (HbS) that causes RBCs defective Hb molecule (HbS) that causes RBCs to become sickle-shaped.to become sickle-shaped.
Eight percent of African American are Eight percent of African American are heterozygous (carriers) for SSA thereby heterozygous (carriers) for SSA thereby inheriting one affected gene or the sickle cell inheriting one affected gene or the sickle cell trait.trait.
One percent of Africa American are One percent of Africa American are homozygous (identical genes) for the disorder, homozygous (identical genes) for the disorder, thereby inheriting a defective gene form both thereby inheriting a defective gene form both parent or SSAparent or SSA
Sickle cell trait (heterozygous) is a generally Sickle cell trait (heterozygous) is a generally mild condition that produce few, if any mild condition that produce few, if any manifestationmanifestation

During decreased oxygen tension in the plasma, the During decreased oxygen tension in the plasma, the hemoglobin S causes the RBCs to elongate, become hemoglobin S causes the RBCs to elongate, become rigid, and assume a crescent, sickled shape causing rigid, and assume a crescent, sickled shape causing the cells to clump together, obstruct capillary blood flow the cells to clump together, obstruct capillary blood flow causing ischemia and possible tissue infraction causing ischemia and possible tissue infraction
With normal oxygenation , the sickled RBCs resume With normal oxygenation , the sickled RBCs resume their normal shape; repeated episodes of sickling and their normal shape; repeated episodes of sickling and unsickling weaken the cell membrane, causing them to unsickling weaken the cell membrane, causing them to hemolyze and be removed.hemolyze and be removed.

There is no know cause but the incidence of non-There is no know cause but the incidence of non-Hodgkin’s lymphomas is linked to viral infections, Hodgkin’s lymphomas is linked to viral infections, immune disorders, genetic abnormalities, exposure to immune disorders, genetic abnormalities, exposure to chemicals, and infection with chemicals, and infection with Helicobacter pyloriHelicobacter pylori
Non-Hodgkin's lymphomas has a similar patho to Non-Hodgkin's lymphomas has a similar patho to Hodgkins disease, also Reed-Sternberg cells are Hodgkins disease, also Reed-Sternberg cells are absent and the method of lymph node infiltration is absent and the method of lymph node infiltration is differentdifferent
In the majority of cases, the disease involves malignant In the majority of cases, the disease involves malignant B cells; the lymphoma usually originates outside the B cells; the lymphoma usually originates outside the lymph nodes; the lymphoid tissues involved become lymph nodes; the lymphoid tissues involved become infiltrated with malignant cells; the cells that make up infiltrated with malignant cells; the cells that make up the lymphoid tissue become abnormal and crowd out the lymphoid tissue become abnormal and crowd out normal cells. normal cells.
