We say that a subgroup H is isolated in a group G if for each x∈ G we have either x∈ H or ⟨ x⟩ ∩ H=1. Z. Janko, in his paper [J. Algebra, 465(2016), 41--61], determined certain classes of finite nonabelian p-groups which possess some isolated subgroups. In this note, a theorem of his paper is refined.
