Skin Cancer01:30

Skin Cancer

6.3K
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...

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

3.3K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Types of Aggregate Grading01:15

Types of Aggregate Grading

1.6K
Aggregate grading is crucial in economically obtaining a concrete mix with adequate strength, reasonable workability, and minimal segregation. There are four types of aggregate gradation: well-graded, uniformly (or one-sized) graded, gap-graded, and open-graded.
Well-graded aggregates include a complete range of necessary size fractions that fit together to create a dense matrix with minimal voids, represented by a smooth, continuous gradation curve. This type of grading ensures good...

Phases of Wound Repair01:28

Phases of Wound Repair

9.0K
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Cells of the Epidermis01:24

Cells of the Epidermis

8.2K
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

Heart Failure IV: Classification and Diagnostic Evaluation01:30

Heart Failure IV: Classification and Diagnostic Evaluation

459
Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

Area of Science:

  • Dermatology
  • Medical Imaging
  • Clinical Research

Background:

  • Acne vulgaris is a common inflammatory skin condition with a high risk of causing permanent scarring.
  • Existing acne scar grading scales have limitations, indicating a need for a validated gold standard for clinical and research use.
  • Objective scar severity assessment is crucial for comprehensive acne evaluation.

Purpose of the Study:

  • To review existing modalities for grading acne scarring.
  • To identify the limitations of current acne scar assessment tools.
  • To emphasize the need for a new, validated scale for objective scar evaluation.

Main Methods:

  • Literature review of existing acne scar grading scales and assessment methods.
  • Analysis of the strengths and weaknesses of various grading modalities, including lesion counting, subjective assessments, and specific scales like ASRS, ECCA, and SCAR-S.
  • Evaluation of imaging techniques for acne scar assessment.

Main Results:

  • Current acne scar grading scales have significant limitations.
  • Most available tools do not adequately consider scar characteristics such as color, depth, or changes over time.
  • Existing methods lack objectivity and validation for reliable assessment of scar progression.

Conclusions:

  • There is a critical need for a new, validated, and objective scale for assessing acne scarring.
  • An improved scale should incorporate scar color, depth, and temporal changes for accurate evaluation.
  • A validated scale will enhance treatment efficacy and facilitate robust clinical research in acne scarring.
