EXAM

Immunoglobulins:
  - Definition: Antibodies produced by plasma cells to identify and neutralize foreign objects like bacteria and viruses.
  - Types of Immunoglobulins:
    - IgG: Most abundant, provides long-term protection, can cross the placenta.
    - IgA: Found in mucosal areas such as the gut, respiratory tract, and urogenital tract, as well as in saliva and breast milk.
    - IgM: First antibody to respond to an infection, effective in forming complexes to target pathogens.
    - IgE: Involved in allergic reactions and defense against parasitic infections.
    - IgD: Functions primarily as an antigen receptor on B cells.
  - Treatments:
    - Immunoglobulin therapy for deficiencies or certain autoimmune diseases.
  - Concerns:
    - Monitoring for autoimmune diseases, allergies, and infections.

Cells:
  - Types of cells involved in inflammation include macrophages, neutrophils, and lymphocytes.
  - Movement in Vesicles:
    - Vesicular transport mechanisms enable cells to move and communicate effectively during inflammatory responses.
  - Composition:
    - Cells are composed of membranes, cytoplasm, and organelles that interact dynamically during the immune response.
  - Electrolytes Influence:
    - Electrolytes such as sodium (Na+), potassium (K+), and calcium (Ca²+) play critical roles in signaling and cellular functions.
  - Cell Stress:
    - Increased production of reactive oxygen species (ROS) and inflammatory mediators can result from stress.

General Information:
  - Importance of maintaining electrolyte homeostasis for cellular function and overall health.
  - Typical electrolyte ranges measured in blood tests:
    - Sodium: 135-145 mEq/L
    - Potassium: 3.5-5.0 mEq/L
    - Calcium: 8.5-10.2 mg/dL
  - Signs and Symptoms:
    - Symptoms of imbalances may include muscle cramps, weakness, fatigue, confusion, and cardiac irregularities.
  - Cellular Level Effects:
    - Impacts excitability of neurons and cardiomyocytes due to changes in membrane potential.

Types of Lymphoma:
- Hodgkin's Lymphoma: Characterized by the presence of Reed-Sternberg cells.
- Non-Hodgkin's Lymphoma: Diverse group with various subtypes, often categorized by the cell type involved (B-cell or T-cell).
Process:
- Lymphoma develops from lymphocytes in the lymphatic system, leading to uncontrolled proliferation.
Diagnosis:
- Confirmed via biopsy of lymph nodes or involved tissues and imaging for staging.

Prognosis:
- Generally examines the likely course and outcome of the cancer, variable based on type and stage.
Pathophysiology:
- Changes in normal cell regulation, leading to uncontrolled cell division and metastasis.
Phases:
  - Initiation: Genetic damage to a cell.
  - Promotion: Proliferation of initiated cells.
  - Progression: Further genetic changes and aggressiveness of the tumor.
  - Etc: Tumor:
    - Types of tumors: Benign vs. malignant with different growth patterns and behaviors.

Pathophysiology:
- Imbalance between the hydrostatic and oncotic pressures in blood vessels, leading to fluid leakage into tissues.
Etiology:
- Can result from cardiovascular issues, lymphatic obstruction, inflammation, and infections.

Types of Burns:
  - First-degree: Affect only the epidermis; characterized by redness and pain.
  - Second-degree: Affect both the epidermis and part of the dermis; blisters and swelling present.
  - Third-degree: Affect all layers of the skin; may appear white or charred with potential nerve damage.
Assessment:
  - Using the ABCDE method:
    - A: Airway
    - B: Breathing
    - C: Circulation
    - D: Disability
    - E: Exposure (and environment)

Types of Arthritis:
- Rheumatoid Arthritis: Autoimmune disorder leading to joint inflammation.
- Osteoarthritis: Degenerative joint disease, often due to wear and tear.
Expectations:
- Management often includes pain control, physical therapy, and, in some cases, surgical intervention.

Definition:
  - Exaggerated immune responses to typically harmless substances, classified into four types (I-IV).
  - Type I: Immediate hypersensitivity (e.g., allergies).
  - Type II: Antibody-mediated (e.g., hemolytic anemia).
  - Type III: Immune complex-mediated (e.g., lupus).
  - Type IV: Delayed-type (e.g., contact dermatitis).

Physiological Changes:
- Aging affects immune function, decreasing response to infections and vaccinations.
- Increases susceptibility to autoimmune conditions.

Overview:
- Chronic pain disorder characterized by widespread musculoskeletal pain, fatigue, and tenderness in localized areas.
Affects:
- Sleep quality, emotional well-being, and overall quality of life.

Definition:
- Also known as shingles; caused by reactivation of the varicella-zoster virus.
Symptoms:
- Painful rash that follows a dermatomal distribution; may experience postherpetic neuralgia.

Overview:
- A condition characterized by weak and brittle bones, increasing the risk of fractures.
Risk Factors:
- Age, sex (more common in women), family history, and low calcium/vitamin D intake.
Prevention:
- Emphasizes nutrition, weight-bearing exercises, and lifestyle modifications.
