Q

What is a prognostic indicator of Hodgkin Lymphoma?

A

Percent of Reed-Sternburg Cells

17
Q

What markers are unique indicating Hodgkin Lymphoma?

A

CD15 and CD30

18
Q

What is the most distinct clincal difference between Hodgkin and Non-Hodgkin’s Lymphoma?

A

Hodgkin – Localized LAD, painless, Neck / Mediastinum – Bimodal Distribution + Constituitional Symptoms
NonHodgkin – Multiple-nodules, extranodal involvment.
- Variable Age Onset - NO Constitutional Symptoms

19
Q

How does the remedy for cyanide poisoning work?

A

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.

20
Q

How do you treat acute iron poisoning?

A

Deferoxamine - chelating agent

21
Q

How do you treat a build up of methemoglobinemia?

A

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.

22
Q

How can non-hodgkins B-cell lymphoma be treated?

A

Rituximab – binds CD20 on B-cells and they will be destroyed by immune system

23
Q

What would you give a patient who is about to undergo a cardiac catheterization due to acute coronary syndrome?

A

Abciximab – binds GBIIb/IIIa receptor to prevent aggregation of platelets during the procedure

24
Q

What is the difference between HbS and HbC?

A

HbS – glutamate –> valine (less negative charge)
– able to sickle and cause disease
HbC – glutamate –> lysine (positive charge)
– minimal anemia and hemalysis

25
What are direct thrombin inhibitors?
Argatraban Bivalirudin Dabigatran
26
What common drugs to treat DVTs causes prolonged PPT, but Normal PT and Thrombin Time?
Factor Xa Inhibitors DIRECT -- Rivaroxaban - Apixaban INDIRECT -- Fondaparinux
27
What would most commonly cause fatigue, fever, bone pain, and dysphagia in a 9 year old male?
T-cell Acute Lymphoblastic Leukemia - -- Less common than B-ALL - -- MEDIASTINAL MASS -- can obstruct vessels and esophagus when they get large enough - -- Superior Vena Cava Syndrome
28
What might be the diagnosis of an 8 year old male who has progressive fatigue, intermittent fevers, bone pain, and enlarged spleen. Lab finding indicate cells with surface markers CD10 and CD19.
B-Cell Acute Lymphoblastic Leukemia - - Most common child leukemia - - CD10, CD19, CD20
29
What is the most common cause of B-thalassemia?
Disruption of transcription, processing, or translation of the protein.
30
If a patient notices everyday when he wakes up in the morning he has hematuria without any other symptoms, what might be found on labs?
Paroxysmal Noctural Hemaglobinuria Pancytopenia -- Aplastic Anemia -- Thrombotic Complications Defective CD55 -- Glycosylphosphatidylinositol anchor **Excessive hemolysis of ALL cells due to complement
