title: [Collateral effects of a project of latex rubber removal in a hospital institution].
abstract: Within a stepwise approach to remove natural rubber latex products from the hospital of Cuneo, latex gloves for examination were completely replaced by nitrile powder free gloves. About a month after their introduction in the whole facility, 31 health care workers (HCW) presented with symptoms of dermatitis characterized by erythema, itching, dryness and chapping on the dorsum of the hands. The symptoms typically appeared 1-3 days after the first nitrile gloves employment, 1-3 hours after they were put on. On the basis of both a detailed clinical examination and specific laboratory tests a diagnosis of irritant contact dermatitis was confirmed in all symptomatic HCW. Samples of nitrile gloves were submitted for analysis by a university toxicological laboratory. Evident traces of a powder containing calcium carbonate were found inside of the gloves. Therefore the declaration of the firm that the product was absolutely powder free must be considered wrong. We suppose that frequent and prolonged contacts between the alcaline pH of the powder found in the gloves and the acid pH of the skin of the hands - together with other individual and environmental factors - could have determined the onset of the symptoms in the HCW. In spite of this adverse reaction, a significant reduction (-68%) of the incidence of latex sensitization and latex-related symptoms was observed in 2006 compared to 2005. We conclude that the complete removal of latex gloves from the workplace is a favourable preventive measure and that switching to nitrile powder free devices is a safe and cost-effective alternative to the latex gloves. However, it is always advisable to demand to the producer a formal declaration of compliance to the security standards of the medical devices.
