Health Risk Assesment of Nickel in Drinking Water

Hygiena 2010, 55(2):40-45  

The most common sources of nickel in drinking water are metallic products situated at the end of plumbing systems, especially taps. For this reason, and because of various water stagnation times, the concentration of nickel at one sampling point can vary within the range of several orders of magnitude, and following overnight stagnation may reach peak values of up to 500 μg/l, i.e. 20 times higher than the current limit value (20 μg/l). Such a single oral nickel dose can provoke systemic contact dermatitis in nickel-sensitive individuals, who represent about 5% of the population.

The project verified the effectiveness of chemical disinfection in circulating lines of hydromassage bath tubs. It dealt with tubs in a health care facility, operated both under the filling of hot water produced from drinking water and iodine-bromine water. Long term inconsistent security of hydromassage systems has resulted in colonization by and significant densities of Pseudomonas aeruginosa organisms in water after operation of the bath tub prior to patient entry. This unsatisfactory performance is explained by inappropriate design of the hydro-massage system and the quality of applied materials (water stagnation in the secondary circuit...

The Risk of Generation of Carcinogenic Para-chloroaniline within Endodontic Therapy of Devitalised Teeth

Ján Kováč, Daniel Kováč

Hygiena 2010, 55(2):54-57  

The purpose of this article is to report on potential risk of formation of para-chloroaniline (PCA), a breakdown product of chlorhexidine (CHX) a toxic and carcinogenic compound. The generation of PCA is a potential consequence of the use of chlorhexidine which has been widely used as an antiseptic agent for routine dental plaque control and irrigation of root canals in endodontic treatment of devitalised, pulpless teeth, for reduction of microbiota.

Hygiena 2010, 55(2):58-60  

Gender differences in the successful treatment of smoking dependence have been identified; women have greater difficulties in quitting smoking compared to men. Women reported higher levels of withdrawal symptoms and craving and diminished effectiveness of nicotine replacement therapy. Sex hormones, especially estrogen, may play a role both in the metabolism of nicotine, cortisol concentrations, carving, withdrawal symptoms and risk of relapse.

Intestinal Microflora: Past and Present

Bohumil Turek, Petr Šíma, Jan Ševčík

Hygiena 2010, 55(2):61-63  

Intestinal microflora greatly influences metabolic processes. Correct nutrition enables an adequate ratio of individual microorganisms in intestinal flora which, as probiotics, play a role in the biochemical and immune mechanisms of prevention in cardiovascular diseases, carcinogenesis, diabetes, and allergies.
