Skin Cancer

4.1K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Assessment of the Cardiovascular System III: Palpation

307
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Skin Diseases and Disorders

3.8K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Assessment of the Cardiovascular System II: Inspection

225
Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

Summary
This summary is machine-generated.

Erythema nodosum (EN) is a common form of panniculitis presenting as painful nodules. It often results from immune reactions to triggers like infections or medications, and typically resolves after treating the underlying cause.

Area of Science:

  • Dermatology
  • Immunology
  • Pathology

Context:

  • Erythema nodosum (EN) is the most common type of acute panniculitis.
  • Characterized by painful, red-to-livid, raised nodules, typically on the shins.
  • Often presents symmetrically.

Purpose:

  • To describe the clinical presentation and common triggers of Erythema nodosum.
  • To highlight the immune system's role in EN development.
  • To emphasize the self-limiting nature of EN after addressing underlying causes.

Summary:

  • EN is an immune response to triggers such as infections, inflammatory conditions, or medications.
  • In about 50% of cases, the specific trigger remains unidentified.
  • Treatment focuses on the underlying pathology, leading to EN resolution.

Impact:

  • Provides a concise overview of Erythema nodosum for healthcare professionals and researchers.
  • Enhances understanding of EN as an immune-mediated condition.
  • Underscores the importance of identifying and treating underlying causes for effective management.
