Skin Cancer01:30

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...

Clinical Applications of Epidermal Stem Cells

2.7K
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...

Burn Injuries01:22

Burn Injuries

2.5K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Phases of Wound Repair01:28

Phases of Wound Repair

6.0K
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...

Overview of Regeneration and Repair01:19

Overview of Regeneration and Repair

4.0K
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.
Regeneration
All animals have varying degrees of...

Area of Science:

  • Dermatology
  • Laser Therapy
  • Scar Revision

Background:

  • Hypertrophic scars are confined to injury sites and may regress.
  • Keloids extend beyond injury borders and do not regress.
  • Histology shows wavy collagen in hypertrophic scars, irregular in keloids.

Purpose of the Study:

  • To evaluate the effectiveness of a hybrid laser device combining 10600 nm Ablative and 1570 nm non-Ablative wavelengths.
  • To analyze scar characteristic improvements in hypertrophic scars and keloids post-treatment.

Main Methods:

  • Retrospective analysis of scars treated with a hybrid laser device (ProScan Hybrid Mode).
  • Treatment involved 40 W/1.3-1.5 ms (CO2) and 12 W/4 ms (1570 nm) in a 1:1 ratio.
  • Outcomes assessed using Vancouver Scar Scale (VSS) and patient satisfaction; statistical significance set at p < 0.05.

Main Results:

  • Significant reduction in VSS scores for both hypertrophic (62% ± 8%) and keloid scars (58% ± 7%).
  • Hypertrophic scars showed statistically significant improvements in VSS, satisfaction, and pain compared to keloids.
  • Only one adverse event (superficial burn) was reported, indicating a favorable safety profile.

Conclusions:

  • The hybrid laser device is safe and effective for treating hypertrophic and keloid scars.
  • Promising results suggest this device is a viable option for scar revision.
  • Further research may explore optimal parameters and long-term outcomes.
