Occupational diseases due to cooling fluids.

Contact dermatitis to cutting fluids is a very frequent cause of occupational skin disease, with different mechanisms for those caused by irritation or allergies. The different allergens in question are many and complex. Different batteries of patch tests are available but the interpretation of the relevance of positive tests is not simple.

Occupational asthma induced by Chrysonilia sitophila in a worker exposed to coffee grounds.

A new case of occupational asthma caused by Chrysonilia sitophila (asexual state of Neurospora sitophila) was diagnosed by molecular identification of the mold and confirmed by skin prick test, peak expiratory flow rate measurements, and experimental immunoglobulin E analysis.

[How to test occupational products brought in by patients].

Where allergic investigations are carried out for occupational dermatitis, appropriate tests must be performed but commercially available batteries are not always suitable for the working conditions and for the products handled by patients. During testing, the products being handled must thus be correctly diluted with full knowledge of their composition in order to prevent harmful effects, particularly caustic effects, and to avoid false positives and false negatives.

Occupational dermatitis to epoxydic and phenolic resins.

Contact dermatitis to epoxydic and phenolic resins are the most frequent contact dermatoses due to plastics, in particular in the form of airborne dermatitis. The chemical formulas of the various components of these resins and their additives are complex and the patch tests available in the trade are insufficient and often arrive at a late stage in the progress of industry, in particular in advanced technologies like aeronautical engineering, shipbuilding or the new floor and wall coverings in buildings. This article is a review of the actions to be taken with these allergies, as well as with regards to their diagnosis, prevention and medico-legal compensation.

Prevalence of and factors associated with hepatic steatosis in patients coinfected with hepatitis C virus and HIV: Agence Nationale pour la Recherche contre le SIDA et les hépatites virales CO3 Aquitaine Cohort.

Background: Hepatic steatosis is a common feature in liver biopsies from patients with chronic hepatitis C and is associated with fibrosis progression. Patients with HIV infection and hepatitis C virus (HCV) coinfection have more rapid progression of liver fibrosis than patients with HCV infection alone. The prevalence and factors associated with hepatic steatosis are not well defined in HCV-HIV-coinfected patients.
