Study Notes

Filaggrin Gene and Skin Impairment

Filaggrin (FLG) gene deficiency is associated with impaired skin barrier function, leading to skin conditions like atopic dermatitis and eczema.
Conditions like asthma and allergic rhinitis have shown a significant association with FLG deficiency.

Diagnosing Atopic Dermatitis

Essential features for diagnosis include pruritus, chronic relapsing course, and a characteristic distribution of rash.
The presence of dry skin is a supportive feature in diagnosing atopic dermatitis.

Triggers and Management of Eczema

Common triggers that exacerbate eczema flares include allergens, irritants, and environmental factors.
Patients manage eczema by identifying and avoiding triggers, which can help reduce the frequency and severity of flare-ups.

Treatment Options for Eczema

Emollients and moisturizers are recommended as the most beneficial formulations for eczema relief.
Baths, specifically bleach baths, may not be significantly more effective than water alone in reducing bacteria on the skin.
Topical steroids are primarily effective in reducing inflammation associated with eczema.
Long-term use of high-potency topical steroids can lead to skin thinning and other adverse effects.

Alternative Eczema Treatments

Crisaborole 2% ointment (Eucrisa) is indicated for mild to moderate eczema when topical steroids are ineffective or poorly tolerated.
Tacrolimus 0.03% is indicated for patients 2 years and older with eczema.
Dupilumab (Dupixent) is associated with conjunctivitis as a potential adverse effect and is approved for individuals aged 6 years and older.
Ruxolitinib cream may cause application site reactions.

Antibiotics and Infections

Oral antibiotics like cephalexin are indicated for treating bacterial infections associated with eczema.
Staphylococcus aureus is the most common organism found in infected eczema lesions.
Topical antimicrobials are generally not recommended due to the risk of resistance and ineffectiveness.

HPV and Wart Treatments

High concentrations of bichloroacetic acid (BCA) or trichloroacetic acid (TCA) can cause skin necrosis as a side effect.
Podophyllin should not be used during pregnancy due to potential fetal harm.
Imiquimod cream works by stimulating the immune response against HPV-induced warts.
Podofilox is a home-applied treatment for genital warts, less effective than provider-applied treatments like podophyllin, especially for perianal warts.

Psoriasis Management

Topical steroids are used to reduce inflammation and itching in psoriasis.
Topical steroids should generally be applied twice daily.
Calcitriol, a vitamin D analog, is utilized in psoriasis treatment.
The use of Anthralin has decreased due to skin irritation issues and the development of more effective treatments.
Narrowband UVB light therapy is a common approach for managing psoriasis.
Tanning beds are discouraged during UVB therapy due to the risk of skin damage.

Actinic keratosis primarily arises from sun damage.
Common treatments for actinic keratosis include fluorouracil, imiquimod, ingenol mebutate, and cryotherapy.
HPV infections are predominantly transmitted through skin-to-skin contact.
Topical eflornithine cream inhibits ornithine decarboxylase, affecting hair growth.
Local irritation is a common reaction following the application of eflornithine cream.

Impetigo and Other Infections

Impetigo typically appears on the face and around the mouth.
Mupirocin is considered a cost-effective topical antibiotic treatment for impetigo.
Kunecatechins may cause local irritation as a side effect and inhibit DNA synthesis in wart treatment.

Botox and Wart Removal

OnabotulinumtoxinA (Botox) is FDA-approved for cosmetic use in smoothing out glabellar lines between the eyebrows.
Surgical excision with a loop-shaped cutting tool is a method for wart removal.
Botox use in individuals over 65 is generally avoided due to increased risk of side effects.

Ketoconazole and Fungal Infections

Ketoconazole combats Malassezia infection by inhibiting ergosterol synthesis.
The shampoo formulation for seborrhea treatment often requires prolonged application to be effective.
