Development of the Italian Version of the Near-Death Experience Scale.

Near-death experiences (NDEs) have been defined as any conscious perceptual experience occurring in individuals pronounced clinically dead or who came very close to physical death. They are frequently reported by patients surviving a critical injury and, intriguingly, they show common features across different populations. The tool traditionally used to assess NDEs is the NDE Scale, which is available in the original English version.

Evaluation of T-cell response to CD3 plus CD28 monoclonal antibodies in HIV-1 infected subjects treated with highly active antiretroviral therapy.

To investigate whether highly active antiretroviral therapy (HAART) could improve CD28 molecule expression and CD28-costimulation pathway function we tested the effect of CD28-costimulation on T cell receptor/CD3 induced proliferative responses in a group of HIV-1-infected subjects with CD4+ cells>200/mmc before and after HAART. CD3-mediated responses are recovered or improved after HAART. However the ability of potentiating the responses through CD28-costimulation seemed conserved before therapy and decreased in parallel with increase of response to CD3 alone.

Contact dermatitis in subjects infected with HIV type 1.

In the course of HIV type 1 infection, up to 90% of patients may have skin disease. We studied a group of 26 HIV-infected patients (15 women, 11 men) with symptoms of skin disease or diffuse itching; they were patch tested for common contactants to determine whether allergic contact dermatitis was the cause of their symptoms. We found that approximately one third of HIV-1-positive patients with cutaneous symptoms not related to allergic contact dermatitis had positive patch tests for environmental contactants; in most of them this sensitization was directly related to skin symptoms.
