skin-conditions — source conflicts

Conflict: [National Eczema Society, n.d.] says pityriasis alba is more common in darker skin than white skin. [Siegfried & Hebert, J Clin Med 2015] say it is equally common in all skin types and only more apparent on darker skin; DermNet (2020) says “perhaps more common”. Unresolved — add to open_questions. (Note: Pityriasis Alba)

Conflict: [Bosma et al., J Dermatol 2021] found pollen-season eczema flares strongly associated with hay fever (OR 42) and pollen sensitisation. [Nishie et al., ISRN Allergy 2012] found the frequency of pollen-season flares did not depend on IgE levels or seasonal allergic rhinitis. Unresolved — add to open_questions. (Note: Pollen)
