Study Notes
Alopecia Overview
- Alopecia refers to hair loss in areas where hair is typically present, classified as localized or diffuse, temporary or permanent.
- Two main types: scarring (scarring alopecia) and nonscarring alopecia.
Hair Growth Stages
- Hair follicles cycle through three stages:
- Anagen: Growth phase
- Catagen: Involution phase
- Telogen: Resting phase
Androgenetic Alopecia
- Most common type of hair loss.
- Males show balding in bitemporal regions, and thinning at the vertex.
- Females experience frontal scalp thinning with an increase in part width, maintaining the frontal hairline.
- Diagnosis often relies on clinical judgment; scalp biopsy may be needed for confirmation.
- Treatment includes Minoxidil and Finasteride; antiandrogens may be used for females with androgen excess.
Alopecia Areata
- An immune-mediated condition affecting hair follicle bulbs, leading to patchy hair loss.
- Presentations can vary from limited patchy areas to total hair loss (alopecia totalis) or complete body hair loss (alopecia universalis).
- Diagnosis is straightforward but may require differentiation from tinea capitis or trichotillomania.
- Treatment typically involves corticosteroids, with a good prognosis for limited cases.
Telogen Effluvium
- Characterized by increased hair shedding due to a shortened anagen phase.
- Possible triggers include postpartum changes, medications, stress, and nutritional deficiencies.
- Diagnosis can involve hair pluck tests; generally resolves when underlying triggers are addressed.
Cicatricial (Scarring) Alopecia
- Refers to permanent damage to hair follicles, often accompanied by pain or discomfort.
- Types include lichen planopilaris, frontal fibrosing alopecia, and discoid lupus erythematosus.
Pediculosis (Lice Infestation)
- Can affect scalp, body, and pubic areas; prevalence among children, especially in schools.
- Head lice are transmitted through shared items; body lice are associated with poor hygiene in overcrowded conditions.
- Diagnosis based on pruritus, presence of nits, and lice; treatment typically involves permethrin or malathion, addressing social circumstances for body lice.
Folliculitis
- Inflammation of hair follicles, often due to Staphylococcus infection; linked to diabetes.
- Symptoms include burning and itching, with pustules forming around follicles.
- Can be caused by various factors including heat (hot tub folliculitis) and friction.
Pseudofolliculitis Barbae
- Commonly known as "razor bumps," often seen in men of color due to curly hair follicles.
- Can cause keloidal scarring and secondary infections.
Rosacea
- Characterized by persistent redness and swelling, often affecting the nose (rhinophyma).
- Manages with topical treatments (metronidazole, ivermectin) and systemic antibiotics (minocycline, doxycycline).
- Advanced cases may require isotretinoin or surgical interventions.
Onychomycosis
- Fungal infection of the nails, predominantly affecting toenails in older adults.
- Most cases are caused by dermatophytes, particularly Trichophyton rubrum.
- Without treatment, onychomycosis can worsen and affect additional nails.
