Study Notes

Acne Vulgaris Overview

Acne vulgaris involves inflammation of the skin due to a combination of factors including hormonal changes and bacteria.
Common symptoms include elevated cholesterol levels, myalgias (muscle pain), fatigue, and increased intracranial pressure leading to pseudotumor cerebri.

Surgical Treatment Options

Comedo Extraction: Physical removal of comedones (clogged pores).
Chemical Peels: Low-concentration peels using acids like α-hydroxy acids, salicylic acid, and trichloroacetic acid promote skin exfoliation.
Intralesional Corticosteroid Injections: Used to reduce inflammation within lesions.

Post-Acne Scarring Treatments

Dermabrasion: Mechanical exfoliation to improve skin texture.
Laser Resurfacing: Uses laser technology to reduce imperfections in skin tone and texture.
Deeper Chemical Peels: More intensive peels to treat scarring.
Filler Substances: Used for discrete depressed scars.
Punch Grafting: Surgical technique for "ice-pick" scars.
Full-Thickness Surgical Excision: Removal of larger hypertrophic or aggregated pitted scars.

Oral Treatment Drugs

Antibiotics:
- Tetracycline derivatives (doxycycline, minocycline): Suppress P. acnes and reduce inflammation.
- Macrolides (erythromycin, azithromycin): Provide antibacterial properties with anti-inflammatory effects.
Hormonal Therapy:
- Combined oral contraceptives block ovarian and adrenal androgens, particularly beneficial for women with hyperandrogenism or PCOS.
- Cyproterone acetate (antiandrogen) combined with estrogens helps regulate severe acne in adults over 25.
Isotretinoin: Standard treatment for severe cases with notable side effects including dry skin and mood changes.

Special Forms of Acne

Infantile Acne: Common in infants; resolves within 1-2 years, characterized by early comedo formation.
Acne Excoriée: Results from systematic excoriation of lesions, often linked to psychological disorders.
Drug-Induced Acne: Manifest as inflammatory papules and pustules from exposure to offending agents like oils and hydrocarbons.
Occupational Acne: Caused by contact with follicle-occluding substances in workplace environments.

Topical Treatments

Topical Retinoids:
- Tretinoin, adapalene, and tazarotene normalize keratinization and have anti-inflammatory properties.
Benzoyl Peroxide: Antimicrobial agent effective against Propionibacterium acnes; reduces acne lesions.
