Why does post-inflammatory hyperpigmentation (PIH) persist longer in individuals with darker skin tones after cutaneous wound healing?

💡 Explanation

PIH persists longer in darker skin because of increased melanin transfer via melanocytes to surrounding keratinocytes through melanosomes during inflammation; therefore, more melanin is deposited into the skin, making hyperpigmentation more pronounced, rather than melanocyte sensitivity decreasing or collagen production being directly inhibited.

• A patient exhibits elevated TSH despite normal T3 and T4 levels, but the thyroid gland appears structurally normal via ultrasound. What explains this phenomenon?
• Why does the liver prioritize glycogen synthesis during the absorptive phase of digestion rather than gluconeogenesis?
• Which outcome occurs when interstitial fluid hydrostatic pressure exceeds the oncotic pressure gradient in leg tissues?
• An elderly patient taking warfarin for atrial fibrillation experiences a fall, leading to a subdural hematoma. Why does warfarin increase the risk of hemorrhage in this case?
• If a child presents with bowed legs and delayed fontanelle closure, which mechanism is most likely impaired, leading to this condition?
• An ICU patient develops acute respiratory distress syndrome (ARDS), increasing alveolar membrane thickness and decreasing surface area. Which consequence follows for blood gas transport?
