SnapshotDx Quiz: May 2022

    TLDR Androgenetic alopecia causes hair thinning due to increased androgen activity, treatable with minoxidil and finasteride.
    The "SnapshotDx Quiz: May 2022" from the Journal of Investigative Dermatology focuses on diagnosing androgenetic alopecia (AGA), a common form of hair loss affecting up to 50% of males and females. AGA is characterized by a heightened response to androgens, leading to progressive hair thinning and follicular miniaturization. The quiz highlights that AGA typically presents with bitemporal thinning in men and vertex thinning in women. The pathogenesis involves increased androgen receptor activity, and first-line treatments include topical minoxidil and finasteride. The document also discusses differential diagnoses such as telogen effluvium, central centrifugal cicatricial alopecia, trichotillomania, and alopecia areata sisaipho, providing detailed descriptions and distinguishing features for each condition.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      Quitting vaping significantly reduced hair loss for a user who was a heavy vaper and also taking finasteride. Some participants suggest nicotine's vasoconstrictive properties may worsen hair loss, while others share personal anecdotes of hair improvement after quitting smoking or vaping.
