This study, undertaken by researchers from the University of Manchester and University of Liverpool, U.K., aimed to find out whether people with non‐blanching erythema are more likely to develop pressure ulcers in future than those without non‐blanching erythema. Henoch-Schonlein purpura (HSP): This typically presents as a purpuric rash on the legs and buttocks and may have associated abdominal or joint pain. Non‐blanching erythema – skin redness that does not turn white when pressed – is an important skin change. Meningococcal septicaemia orother bacterial sepsis: This presents with a feverish unwell child. Potentially helpful investigations include: Patients with a non-blanching rash always require urgent referral and investigation unless there is a clear and unconcerning cause. Definitive management will depend on the underlying cause.
