HIGH PREVALENCE OF Strongyloides stercoralis INFECTION AMONG THE ELDERLY IN BRAZIL

SUMMARY Little is known about the frequency of intestinal parasites in the elderly due to a lack of attention given to the occurrence of these infections among older adults. This study compares the frequency of Strongyloides stercoralis and other enteroparasites between elderly living in nursing homes (n = 100) and those noninstitutionalized (n = 100) from Uberlândia, state of Minas Gerais, southeastern Brazil, associated with data of epidemiological and socio-demographic conditions. Through coproparasitological examination of both groups, enteroparasites were detected in 15 of 200 individuals examined (7.5%; CI: 5.1- 9.9). S. stercoralis was the most frequent parasite 10/200 (5%; CI: 4.2-5.8), being significantly higher in males and in individuals with autonomy for daily living activities. There were no statistical differences in the prevalence of parasites between the two groups compared. In conclusion, S. stercoralis infection was highly prevalent in elderly patients and it does not depend on whether the individual was institutionalized or not

Entwicklung einer Bohr- und Probenentnahmetechnik in kontaminierten Bereichen. Teilvorhaben GH 1: Entwicklung von Dichtungssuspensionen und Dichtmassen Schlussbericht

The project deals with the development of a drilling and sampling method for active and inactive hazardous waste disposal sites and other contaminated areas. While drilling through the contaminated waste body, a suspension is injected through the cutter head of the hollow auger. Using a hollow auger in combination with a suspension prevents leakage of contaminated water. After sampling with a special device (ORKUS-Sonde) for orientated coring of undisturbed samples, a different suspension which serves as a seal is filled in instead of the sampled soil column. Sampling cylinders of 1 m length and 50 mm radius are used for sampling in the field. The samples are of good quality for geotechnical tests and are free of contamination from other soil layers. Therefore, these samples can be used to determine the contamination front in natural soils and technical soil liners. Up to now, this undisturbed sampling method has been tested at six sites in gravel, sand, slit, clay, consolidated clay and till. A ram of 80 kg weight beats down the sampling device. A vibration-technique (VIBRA-CORER) in combination with low pressure has also proved to be very effective. In about 100 experiments different suspensions are created. In lab experiments the suspensions are tested in permeability, injectability, hardening time and behavior and chemical resistance ot inorganic and organic leachates.
