  • The forehead and face become smooth and unlined in fascioscapulohumeral dystrophy (Landouzy-Déjérine). [101]
  • Card EA-010 mentions that gouty tophi form in the earlobes. [102]
  • The solubility of uric acid at pH 7.4 and 37°C is 6.8 mg/dL, versus 4.5 mg/dL at 30°C. Thus, it is possible to have gout (precipitation of urate crystals) without hyperuricemia if the temperature, and other conditions, are right. This article presents such a case. [103]
  • Mentions that livedo reticularis is usually most evident on the lower limbs, where cooler temperatures increase the blood viscosity. [104]
