Summary
Keloid and hypertrophic scars result from abnormal wound healing, causing excessive collagen. Various treatments exist, but understanding scar pathophysiology is key to developing better therapies.
Area of Science:
- Dermatology
- Wound Healing Research
- Regenerative Medicine
Background:
- Keloid and hypertrophic scars are aberrant wound healing responses.
- Characterized by dysregulated growth and excessive collagen deposition.
- These scars cause significant cosmetic and functional issues for patients.
Purpose of the Study:
- To elucidate the pathophysiology of keloid and hypertrophic scars.
- To differentiate these scars from normal wound healing.
- To review scar classification and comprehensively detail treatment modalities.
Main Methods:
- A thorough literature review was conducted.
- Relevant publications on scar pathophysiology, classification, and treatment were identified.
Main Results:
- Cytokines (e.g., IL-6, IL-8, IL-10) and growth factors (e.g., TGF-β, PDGF) are implicated in scar pathophysiology.
- Treatments include conventional (dressings, steroids), surgical (excision, cryosurgery), and adjuvant therapies (radiation, interferon, 5-FU, imiquimod, etc.).
Conclusions:
- Keloid and hypertrophic scars present a persistent clinical challenge with functional and aesthetic implications.
- Current therapies employ diverse mechanisms.
- Further research into pathogenesis is crucial for developing advanced, targeted treatments.

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

1
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

6.5K
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.

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...

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

01:19Overview of Regeneration and Repair
5.7K
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.
