Plasma Cell Myeloma mostly occurs in who??
Where does Plasma Cell Myeloma often go to
Often goes to the Spine and Flat bones of head (calveria)
What happens when Plasma Cell Myeloma goes into the spine or flat bones of the head??
When the cells invade it causes a lytic reaction ---> breakdown ----> decreased minerals ---> holes
The lytic reaction in Plasma Cell Myeloma triggers what and are more prone for what ??
The reaction triggers osteoplastic reaction and are prone to pathologic fractures
The osteoplactic reaction in Plasma Cell Myeloma is what to a disease
it is secondary to a disease
How does a pathologic fracture happen
There is no trauma involved. a sneeze can cause the fracture
In Plasma Cell Myeloma what do the malignant plasma cells secrete??
The plasma cells secrete antibodies called Bence-Jones protiens
What are Bence- Jones proteins are what kind of antibody??
Where can Bence-Jones proteins be detected in ??
in the blood or urine can aid in diagnosis.
What are the two kinds of Lymphoma??
What is Hodgkin Disease

What Cell is not present in Non-Hodgkin Disease??
No Reed-Sternberg cells
Hodgkins disorder of the lymph nodes typically ...
stay in the nodes
Non-Hodgkins lymphoma is very
Unpredictable in its spread and is often disseminated at diagnosis.
HIV infects what cells
Infects Helper T cells (CD4+ Lymphocytes)
The loss of Helper T cells causes what??
HIV The viruse has found to be present but not transmitted in what ??
- saliva and tears,
- amnitoic fluid,
- feces and aerisol,
- cerebral spinal fluid
HIV types 1 and 2 are
retroviruses that primarily infect CD4+ lymphocytes and macrophages
HIV is acquired primarily through what?
- sexual transmission via semen and vaginal and cervical secretions;
- through parenteral transmission via blood,
- contaminated needles/syringes;
- through perinatal transmission from an infected mother to her infant antepartum, intrapartum, and postpartum
- via breast milk.
Who are at greatest risk of HIV infection include
- homosexual and bisexual men,
- IVDs who share needles or syringes,
- sexual partners of those in high-risk groups,
- infants born to infected mothers.
Who is at the Highest risk for HIV??

Latency period can last years to decades
You are considered to have aid when you CD4+ count is what ??
When CD4+ count is less than 200/ul
What is the seroconversion phase of the HIV infection??

All body systems
Early HIV infection is characterized by
fever, chills, headaches, nausea, vomiting, diarrhea, fatigue, weakness, arthralgia, sore throat, stiff neck, photophobia, irritability, and rash.
The most significant systemic symptom of HIV is
Malnutrition or wasting,
due to a combination of factors, including an elevated metabolic rate, chronic inflammation, malabsorption, anorexia, and the effect of multiple opportunistic insults.
Management of HIV and AIDS includes the use of
