National survey of psoriasis flares after 2009 monovalent H1N1/seasonal vaccines.

Background: Psoriasis is a common chronic immune-mediated disease resulting from interactions of a genetic background with environmental triggering factors such as stress and infection. So far, there is very limited information available about the impact of vaccine stimuli on psoriasis course.

Objective: To collect cases of psoriasis flares occurring after vaccination through a national survey.

Innovative method for prioritizing emerging disinfection by-products (DBPs) in drinking water on the basis of their potential impact on public health.

Providing microbiologically safe drinking water is a major public health issue. However, chemical disinfection can produce unintended health hazards involving disinfection by-products (DBPs). In an attempt to clarify the potential public health concerns associated with emerging disinfection by-products (EDBPs), this study was intended to help to identify those suspected of posing potential related health effects.

Cutaneous and mediastinal lymphadenitis due to Mycobacterium kansasii.

Mycobacterium kansasii most commonly causes a slowly progressive pulmonary disease. Skin and disseminated infections are seen less frequently and only in immunocompromised hosts. To our knowledge, no case of Mycobacterium kansasii infection or skin infection associated with additional organ involvement in an immunocompetent patient has been reported.

Dioxins in adipose tissue of non-occupationally exposed persons in France: correlation with individual food exposure.

We evaluated individual adipose tissue (subcutaneous lipomas) dioxin contamination in non-occupationally exposed persons living in France (adult patients undergoing a surgical ablation of benign lipomas), in relation to the corresponding individually evaluated mean daily dietary dioxin intake (DDDI). The diet survey (questionnaire) included information on consumption of meat, fish, milk and dairy products, from which the individual DDDI was calculated. Sixteen subjects participated in this study.

[General population exposure to dioxins, human ubiquitous pollutants].

This paper gives an overview of the environmental or background exposure of general population to dioxins, polychlorinated dibenzo-para-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF), originating from a variety of industrial and thermal processes and recognized as cancerous and toxic substances. The daily consumption of low-level contaminated food, mainly of animal origin, leads to the accumulation of dioxins in the human body. To determine the background exposure, human milk, adipose tissue or blood from many geographical locations (except France) have been used as bioindicators for body burden of dioxins.
