Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

3.3K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Standard Precaution

2.7K
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

7.5K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

PPE Use in Healthcare Settings I: Donning

1.6K
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Personal Protective Equipment01:20

Personal Protective Equipment

2.1K
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

PPE Use in Healthcare Settings II: Doffing

The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Area of Science:

  • Dermatology and Public Health

Background:

  • Cumulative ultraviolet radiation (UVR) exposure is a primary driver of skin cancer and photo-aging across all skin types.
  • Visible light radiation contributes to the pathogenesis of pigmentary conditions.
  • Intense childhood UVR exposure is a significant risk factor for melanoma development later in life.

Purpose of the Study:

  • To emphasize the importance of comprehensive sun protection strategies.
  • To address common myths and barriers to sunscreen use.
  • To provide evidence-based guidance for patient counseling on daily sun safety.

Main Methods:

  • Review of scientific literature on UVR and visible light effects on skin.
  • Analysis of current recommendations for sun protection.
  • Identification of common misconceptions regarding sunscreen.

Main Results:

  • Effective sun protection requires a daily, multifaceted approach when the UV index is 3 or higher.
  • This includes broad-spectrum sunscreen (SPF 50+), protective clothing, hats, sunglasses, and shade.
  • Certain medications can increase photosensitivity, necessitating stricter sun protection.

Conclusions:

  • Patient counseling should extend beyond sunscreen to incorporate practical, evidence-based sun safety practices.
  • Addressing myths about sunscreen (e.g., endocrine disruption, nanoparticle toxicity) is vital.
  • Empowering patients to integrate sun safety into daily routines is the ultimate goal for preventing skin damage.
