What is the difference between slow developing Anemia and Rapid Onset of anemia?

Slowly developing anemia is tolerated and there may be no symptoms until hemoglobin concentration and hematocrit fall below one half of normal.
Rapid onset of anemia will result in an abrupt lack of oxygen transport to the lungs and muscles

Why would patients with anemia need caution in PT clinics?

Patients have diminished exercise tolerance
PTs must be cautious during exercise testing and when prescribing, dosing, and progressing exercises
Consider tolerance and/or perceived exertion levels (Borg Scale)
Exercise for any client with anemia should first be approved by their physician

What is Polycythemia?

This is characterized by increases in both the number of RBCs and the concentration of hemoglobin. This condition increases whole blood viscosity and volume
- Can also be associated with living in elevations about 3500 ft

What is the difference between Primary and Secondary Polycythemia?

Primary: Is a relatively uncommon neoplastic disease of the bone marrow of unknown etiology (Polycythemia vera) <- {This can cause headache, dizziness, toe joint swelling (gout), itchiness after shower

Secondary: Is a physiologic condition resulting from a decreased oxygen supply to the tissues (Smoking, tumors, lung disorders, living or exercising in high altitudes)

What are the Clinical Signs and Symptoms of Polycythemia?

Directly related to the increase in blood viscosity
- General malaise and fatigue
- Shortness of breath
- Headache
- Dizziness
- Fainting
- Hypertension (Therapist should watch for this)

These were the one highlighted in the PP, there are more s/s

What are the Causes of Sickle Cell? What demographic is sickle cell common in? How is it diagnosed?

Causes:
- Genetic mutations in the hemoglobin beta gene
- In has a inherited pattern

Common in:
- African Americans
- Hispanic Americans

Diagnosis:
- A blood test to check for hemoglobin S (Abnormal shape)

What are the Clinical Signs and Symptoms of Sickle Cell?

Recurrent episodes of Vaso-occlusion and inflammation results in progressive damage to most organs, including the brain, kidneys, lungs, bones, and cardiovascular system. CVA and cognitive impairments are a frequent and severe manifestation
Pain: caused by the blockage of sickled RBCs forming sickle cell clots. The clots may be in an organ, bone, or joint of the body. Painful episodes of ischemic tissue damage may last 5 or 6 days and manifest in many different ways, depending on the location of the clot.

What is Leukocytosis?

An Infectious Disease
- It can be associated with an increase in circulating neutrophils, which are recruited in large numbers early in the course of most bacterial infections

What is Leukopenia?

This occurs in many forms of bone marrow failure such as that following antineoplastic chemotherapy, or radiating therapy, in overwhelming infections, in dietary deficiencies, some medications, or in autoimmune diseases. Unlike leukocytosis, leukopenia is NEVER beneficial

What are signs and symptoms for leukocytosis?

Fever
Symptoms of localized or systemic infection
Symptoms of inflammation or trauma to tissue

What are signs and symptoms for Leukopenia?

Sore throat, cough
High fever, chills, sweating
Ulcerations of mucous membranes (mouth, rectum, vagina)
Frequent or painful urination
Persistent infection

What are the functions of Platelets?

Platelets (Thrombocytes) function primarily in hemostasis (to stop bleeding) and in the maintenance of capillary integrity
They function in the coagulation (blood clotting) mechanism by forming hemostatic plugs in small ruptured blood vessels or by adhering to any injured lining or larger blood vessels

What is normal Platelet count for adults and children?
What is critically low and high platelet count?

150,000-350,000 /uL (Microliters)
Critically Low <20,000 /uL
Critically High >1,000,000 /uL

What are 2 platelet Disorders?

Thrombocytosis
Thrombocytopenia

What is Thrombocytosis?

An Increase in platelet count (exceeds 1 million/mm3) that is usually temporary. Tendency to clot because blood viscosity is increased, high platelet count, resulting in intravascular thrombosis of the
sludged platelets
- Peripheral BV, particularly in the fingers and toes, are affected

What is Thrombocytopenia?

A Decrease in the number of platelets (less than 150,00/mm3) in circulating blood, can result from decreased or defective platelet production or from accelerated platelet destruction. Spontaneous Bleeding

What are the Clinical Signs and Symptoms of Thrombocytosis?

Thrombosis
Splenomegaly (enlarged spleen)
Easy bruising

What are the Clinical Signs and Symptoms of Thrombocytopenia?

- Bleeding after minor trauma - Spontaneous bleeding - Menorrhagia (excessive menstruation) - Gingival bleeding - Melena (black, tarry stools)

What are the most common causes of Thrombocytopenia in the PT clinic?

- Bone marrow Failure - Radiation - Aplastic anemia - Leukemia - Metastatic carcinoma Cytotoxic Agents (Chemotherapy) - Medications - NSAIDs, including aspirin - Methotrexate - Gold - Coumadin/Warfarin

What is hemophilia?

*Coagulation Disorder* - A hereditary blood-clotting disorder caused by an abnormality of functional plasma-clotting proteins known as factors VIII and IX - People with hemophilia **bleed longer than those with normal levels** of functioning factors VIII or IX, but **the bleeding is not any faster than would occur in a normal person with the same injury**

What is Acute Hemarthrosis? What are some symptoms from this?

Bleeding in the joint spaces is the most common clinical manifestation of the hemophilia S/S: - Tingling or prickling sensation - Stiffening into the position of comfort - Decreased ROM - Pain - Swelling - Tenderness -Heat

With Bleeding of other systems, what is common with a Muscle Hemorrhage?

*2nd most common type* - Gradual intensification of pain - Protective spasm of the muscle - **Iliopsoas is the most affected muscle** - Loss of sensation

With Bleeding of other systems, what is common with bleeding involving the CNS?

- Intraspinal Hemorrhage (rare) - Intracranial Hemorrhage, can cause: --Irritability, lethargy --Seizure --Death --Apnea --Unequal pupils

With Bleeding of other systems, what is common with bleeding involving the GI system?

- Abdominal pain and distention - Melena (blood in stool) - Hematemesis (Vomiting blood) - Fever - Lower abdominal/groin pain due to bleeding into wall or large intestine or Iliopsoas muscle - Flexion contracture of the hip due to spasm of the iliopsoas muscle secondary to retroperitoneal hemorrhage

When screening for Hematologic Diseases, what are some Special Questions to ask?

- Have you recently been told you are anemic? - Have you recently had any serious blood loss (possibly requiring transfusion)? *Also consider Anemia; jaundice/hepatitis post-transfusion* - Have you ever been told you have a congenital heart defect (also chronic lung/heart disorders)? *Polycythemia; also possible with a history of heavy tobacco use* - Do you have a history of bruising easily, nosebleeds, or excessive blood loss? (Can be polycythemia, hemophilia, thrombocytopenia) - Have you been exposed to occupational or industrial gases, such as chlorine or mustard gas?

When should there be a Medical Referral or Consultation?

- Any patient with suspicion of anemia (weakness and fatigue, SOB) not previously diagnoses - Use of certain drugs, exposure to radiation, or recent cytotoxic cancer chemotherapy can affect the bone marrow - Keep an eye on any history of excessive menses, folate-poor diet, alcohol abuse, drug ingestion, family history of anemia, and family roots in geographic areas where RBC enzyme or hemoglobin abnormalities are - Presence of severe bruising, hematomas, and multiple petechiae usually indicates a platelet count well below normal - Clients who have been diagnosed with hemophilia, medical referral should be made when any painful episode develops in the muscle(s) are joint(s)

When should the patient require Immediate Medical Attention?

When they present with signs and symptoms of thrombocytopenia (decreased platelets, excessive bleeding, petechiae, severe bruising) previously unseen or unreported to the physician
