Hematology Flashcards
What is the most common Non-Hodgkins lymphoma in adults?
Diffuse Large B-cell Lymphoma
What lymphoma is associated with Hoshimoto’s and Sjorgen Syndrome?
MALToma — Marginal Cel Lymphoma
If you are diagnosed with Marginal Cell Lymphoma of the Antum of the stomach, what should be the treatment?
Treat the H.Pylori and Maltoma should resolve.
What characteristic of Follicular Lymphoma makes it become carcinogenic?
BCL-2 Activation – anti-apoptotic, but too much, prevents cell from dying.
t(14,18)
If irregular myeloid cells have a t(15,17), what most likely is the occuring?
Acute Myeloid Leukemia – M3
What leukemia is associated with DIC and how do you treat it?
AML – t(15,17)
– All trans retinoic acid – allows the maturity of the cells and the patients have to take it the rest of their lives.
What translocation is associated with Cyclin D1 over activation?
Mantle Cell Lymphoma – t(11,14)
What is always associated with Chromic Myeloid Leukemia?
Philadelphia Chromosome – t(9,22)
What cancer and translocation is associated with c-myc oncogene activation?
Burkitt Lymphoma – t(8,14)
What histology is associated with Burkitt Lymphoma?
Starry Sky Appearance – sheets of solid lymphocytes with interspaced macrophages
What Non-Hodgkin lymphoma is associated with EBV?
Burkitt Lymphoma (African Type) – Jaw Lesion
What most commonly is associated with sporatic t(8,14) translocation?
Burkitt Lymphoma - Localized to Pelvis / Abdomen – Peyer’s Patches/Testicle
What is the most common T-cell lymphoma in adults? What is a risk factor?
Adult T-cell Lympoma – HTLV Virus (IV Drug Abuse)
What are the similarities between Adult T-cell Lymphoma and Multiple Myeloma?
- Lytic Bone Lesions
- Hypercalcemia
What is associated with atypical CD4+ cells with a cerebriform nuclei with skin patches and plaques?
Mycosis Fungoides
– if systemic Sezary Syndrome
What is a prognostic indicator of Hodgkin Lymphoma?
Percent of Reed-Sternburg Cells
What markers are unique indicating Hodgkin Lymphoma?
CD15 and CD30
What is the most distinct clincal difference between Hodgkin and Non-Hodgkin’s Lymphoma?
Hodgkin – Localized LAD, painless, Neck / Mediastinum – Bimodal Distribution + Constituitional Symptoms
NonHodgkin – Multiple-nodules, extranodal involvment.
- Variable Age Onset - NO Constitutional Symptoms
How does the remedy for cyanide poisoning work?
Give the patient Amyl-Nitrite – converts heme into methemoglobin (Fe+2–>Fe+3), which then Cyanide has a higher affinity for and is bound up in heme instead of ETC.
How do you treat acute iron poisoning?
Deferoxamine - chelating agent
How do you treat a build up of methemoglobinemia?
From oxidative stress converting the irons into different forms that do not bind oxygen.
– Treated with Methylene Blue, will reduce them back into Fe+2 form.
How can non-hodgkins B-cell lymphoma be treated?
Rituximab – binds CD20 on B-cells and they will be destroyed by immune system
What would you give a patient who is about to undergo a cardiac catheterization due to acute coronary syndrome?
Abciximab – binds GBIIb/IIIa receptor to prevent aggregation of platelets during the procedure
What is the difference between HbS and HbC?
HbS – glutamate –> valine (less negative charge)
– able to sickle and cause disease
HbC – glutamate –> lysine (positive charge)
– minimal anemia and hemalysis
