Summary
Actinic keratoses are sun-induced skin lesions that may develop into cancer. Current treatments include destructive therapies and topical medications like fluorouracil, imiquimod, and diclofenac.
Area of Science:
- Dermatology
- Oncology
Background:
- Actinic keratoses (AKs) are pre-malignant skin lesions common on sun-exposed skin.
- Prevalence increases with age, and AKs can progress to squamous cell carcinoma.
- Treatment decisions balance cosmetic concerns, symptom relief, and cancer prevention.
Purpose of the Study:
- To review current treatment modalities for actinic keratoses.
- To highlight the efficacy of both ablative and topical therapies.
- To identify gaps in evidence for treatment comparisons.
Main Methods:
- Literature review of ablative therapies (cryosurgery, curettage, photodynamic therapy).
- Review of topical treatments including fluorouracil, imiquimod, and diclofenac.
- Analysis of evidence comparing different treatment approaches.
Main Results:
- Ablative therapies offer destructive treatment options for localized AKs.
- Topical therapies are effective for patients with multiple lesions.
- Limited controlled trials exist for direct comparison of treatment modalities.
Conclusions:
- Effective treatments for actinic keratoses include ablative and topical options.
- Further comparative studies are needed for evidence-based treatment selection.
- Preventing malignancy and metastasis is a key goal in AK management.

01:30Skin Cancer
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.

01:27Acne Infection
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...
01:12Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
01:19Clinical Applications of Epidermal Stem Cells
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 EpiSCs...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
