A case of mycosis fungoides and lymphomatoid papulosis occurring simultaneously in a child.

Several studies have reported an association between lymphomatoid papulosis and other lymphomas, such as mycosis fungoides, Hodgkin's disease, and anaplastic large cell lymphoma. The association between lymphomatoid papulosis and mycosis fungoides has been reported to be between seven and 39 percent. Although a relationship is acknowledged between lymphomatoid papulosis and mycosis fungoides, our understanding is limited.

Prevalence and factors associated with use of placebo control groups in randomized controlled trials in psoriasis: a cross-sectional study.

Background: The ethics and science of using placebo control groups in clinical trials have been widely debated. Few studies, however, have examined factors associated with choice of control group.

Objective: Our aim was to assess the prevalence of use of placebo controls in randomized controlled trials in psoriasis and to identify factors associated with use of placebo controls in these trials.
