Summary
Actinic keratosis (AK) is a pre-malignant skin lesion. New imiquimod 3.75% offers a shorter, effective treatment option for facial AKs with potentially fewer side effects.
Area of Science:
- Dermatology
- Oncology
Background:
- Actinic keratosis (AK) is a common pre-malignant skin lesion.
- AKs can progress to squamous cell carcinoma (SCC).
- Numerous treatment options exist, including destructive, topical, and procedural therapies.
Purpose of the Study:
- To review current treatment options for AKs.
- To highlight the recent approval and potential benefits of imiquimod 3.75% for facial and scalp AKs.
Main Methods:
- Literature review of AK treatments.
- Discussion of topical field therapies, including 5-fluorouracil, imiquimod, and diclofenac gel.
- Focus on imiquimod 3.75% (Zyclara TM) for facial and scalp AKs.
Main Results:
- Imiquimod 3.75% is a new option for facial and scalp AKs.
- This formulation allows for larger treatment areas and shorter treatment durations compared to imiquimod 5%.
- Potential for reduced local skin reactions with imiquimod 3.75%.
Conclusions:
- Treatment choices for AKs depend on efficacy, side effects, cosmetic outcomes, and patient adherence.
- Imiquimod 3.75% presents a viable alternative for managing facial and scalp AKs.
- Further comparative data is needed to establish a definitive treatment algorithm.

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...
01:19Clinical 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...
01:12Renewal 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,...

The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...
01:22Burn Injuries
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...
