Parazytozy w obozie młodzieży arabskiej

Examinations were made in 21 youths from Oman. In spite of dehelminthization prior to their arrival to Poland, they were found to be invaded by Lamblia intestinalis, Ancylostoma duodenale, Enterobius vermicularis, Trichuris trichiura and Hymenolepis nana.
For at least 15 years uniform coproscopic methods have been recommended for Polish sanitary-epidemiologic centres. This is expected to result in comparison of results from various regions and development of epidemiologie maps of the country. Hitherto, 4 methods have been advocated: direct smear, decantation, after Rivas and NIH procedures for enterobiosis. Some recent techniques such as PVA, MIF fixation, trichrome staining, MIFC, procedures after Engelbrecht, Kato and Miura are being advanced. The pertinent comparative studies showed that the modifications of the Telemann's method, for instance, after Miyagava (1913) or Rivas (1928) yield results inferior to those obtained by other methods and consequently should be abandoned in the field practice. Quite satisfactory is the method of decantation, for instance with MF-fixed material. For better recognition of Protozoa the recommended method is that of PVA with subsequent trichrome staining. The pepsine-ether method of Engelbrecht is very good, but only for thick shelled eggs of parasites. The method of Kato and Miura is more efficient than an ordinary smear, but far less recommendable as to the yield. The presented views are debatable, and of course the freedom of choice is left for the investigator
Background: The aim of this study is to provide the first analysis of finger ridge counts and fluctuating asymmetry in myopia, in order to evaluate dermatoglyphic role as a morphological biomarker. Materials and methods: Study sample consisted of 102 participants recruited from freshman students’ population of the University of Priština-Kosovska Mitrovica. Prints were taken by standard ink and paper method. Differences in mean ridge counts between examined groups were analysed by ANOVA analysis of variance. Fluctuating asymmetry assessment was performed by using correlation method (p < 0.05). Results: Analysis has identified myopic males as the group with the most prominent differences of examined dermatoglyphic parameters. Myopic males, compared to controls, have significantly higher ridge counts for left and right ring and little finger, as well as total ridge count. Also, this group has recorded significant difference in fluctuating asymmetry correlation score for middle finger, and borderline significance for thumb and ring finger. Conclusions: Overall findings of this study have indicated that dermatoglyphics might serve as a morphological biomarker, especially in myopic males, selecting them as the group with dermatoglyphic differences that might be suggestive of higher developmental instability. Although promising, the present results should be considered as preliminary until future investigations replicate them in a larger sample. (Folia Morphol 2019; 78, 2: 425–430)
