Straight Hair Associated with Interferon-Alpha Plus Ribavirin in Hepatitis C Infection

The document describes a study where five retired physicians with chronic X-ray dermatitis were treated using topical 5-aminolaevulinic acid photodynamic therapy (ALA-PDT). Previous treatments such as cryotherapy, and topical antibiotics or corticosteroids had failed to provide relief. ALA-PDT, which involves applying ALA cream to lesions and exposing them to a specific light source, resulted in complete clinical remission for two patients and partial remission for three, with no adverse effects reported. Pain relief was a significant early benefit of the treatment. The study notes the advantages of ALA-PDT, such as low toxicity, minimal side effects, cost-effectiveness, and the potential to prevent surgical interventions. However, the absence of a control group not receiving hyperthermia means the effect of hyperthermia on treatment outcomes is unclear. The document also mentions a retrospective analysis of pemphigus vulgaris in pregnancy, but it is not the primary focus.
