[Transmission of "barber's itch" by bathing?].

Pathogenic fungi find a favourable environment in baths for multiplication and distribution. So diseases caused by dermatophytes are often observed in connection with a visit of a bath. With regard to transmission of a "barber's itch" caused by fungi in consequence of the visit of a bath, there have still no results been published. Considering previous knowledge about epidemiology, mechanism of invasion, living, and multiplication of pathogenic fungi it seems unlikely that a transmission of the germs of "barber's itch" takes place due to the visit of a public bath. The expression "barber's itch" is not uniformly used; thus, if visitors make complaints about this affection, an etiological differentiation is required.

[Evaluation of the exposure levels to radioactivity in the hot-spring environment of the Island of Ischia during a year].

It is known that the decay products of the U-238 are findable in nature in certain materials (such as tufa, limestone, etc.), therefore some populations are naturally exposed to radiations originated by building materials, houses and isotopes present in drinking-waters. It is evident that, for example, the residents of Campania or Lazio will be involved, on such conditions and during their whole life, in the action of natural radiations of decay products of Uranium and consequently of Radon, which is originated and, as gas, also findable in the air of those indoor areas, at a concentration inversely proportional to the relevant ventilation factors. Furthermore, it is known that this isotope is always found in thermal waters too and sometimes at levels which make them classify as radioactive and with therapeutic properties still subjects of studies and researches. Actually, presence of Radon in warm waters is particularly evident in some basins (the Baths of Badgastein in Austria) and is also findable in some italian thermal towns such as Merano Laurisia, Abano, Baths of Lucca or the island of Ischia itself. All underground waters and especially the warm ones, including, those of Ischia basins, hold radioactive isotopes, since their composition is related to the nature of the underground, which they come from, and is strongly influenced by the kind of rocks present in that area, by the granulometry of the geological strata or by existent fractures, by flow speed and finally by solubilization capacity. On such conditions it is evident that all waters, during their scouring, will be enriched by Radon 222 (a gaseous, therefore more soluble, element); just because of its physical state, it will be more present in external environment in case of warm waters such as those ones now examined. Consequently the environmental state from a radioecological point of view of the utilized waters has to be considered, as well as any other thermal resort, fundamentally due to Radon (Rn) and to the relevant decay products. As a matter of fact, whereas from the family of Uranium come Radon (Rn 222), Lead (Pb 210) and Polonium (Po 210), these last two, respectively with halving-times of 22.3 years and 138.4 days, from the family of Thorium (Th 232) originates Radon (Rn 220 in past times defined "Toron" according to its "forebear") and Lead (Pb 212 with a halving-time of 10.6 hours).(ABSTRACT TRUNCATED AT 400 WORDS)

The use of arginine brilliantgreen glucose peptone broth (ABGP medium) as a primary culture medium for Pseudomonas aeruginosa.

A new medium is described for the isolation of P. aeruginosa organisms which have been damaged by chlorination. This medium utilises the fact that with arginine. P. aeruginosa produces a strongly alkaline reaction resulting in an easily identified colour change from gray-green to blue-violet. The indicators used for this purpose are bromothymol blue and cresol red. The medium may be used with either the membrane filter or the liquid enrichment technique. Incubation is at 37 degrees C for 24 or 48 h.

What school children need to learn about injury prevention.

Unintentional injuries are the leading cause of death and a major cause of morbidity among school age children. A survey of the educational needs concerning injury prevention of a group of fifth and sixth grade children (ages 10-12) in Holliston, MA, revealed educational deficiencies, including bicycle safety, seatbelt use, firearms use, and water safety. It is well known that the use of helmets can prevent bicycle injuries. Yet, not one of the children in this study reported using a bicycle helmet. Although most States have laws requiring seatbelts for young children, school age children are not covered by this legislation. The hazards of firearms have been well-documented. But it is clear that the children surveyed were in need of education about firearms; nearly half had used some form of firearms. Individual counseling by pediatricians combined with school- and community-based programs can address injury prevention. It is anticipated that many pediatricians will begin using the questionnaire for school age children as that component of the American Academy of Pediatrics Injury Prevention Program is introduced.

[Improving the quality of bathing water by oxygen releasing substances].

The bath water of an indoor swimming bath of 25m length has been preparatory acc. to TGL 37780/02 and by procedings of flocculation-filtration-chlorination. the filter drain water (clear water) had been supplemented by 20...30 percentage hydrogen peroxide or potassium peroxide sulphate. The reaction with chlorine existing in surplus and hydrogen peroxide results in a spontaneous formation of nascinating oxygen. The occurring wet oxidation of contents substances of the bath water also with an increased frequentation of the indoor swimming bath results in reduced rates of CSVMn and chloramine. This fact can be explained by the concurring reaction between oxygen and chlorine. Because of its low expense, the forced decomposition of hydrogen peroxide could be an alternative for utilization of ozone in small bathes. Contrary to this the combination potassium peroxide sulphate/chlorine will not result in such a significant improvement of the quality of bath water.
