[en] The Ascaridiasis is a problem of public health in the most countries located in the third world, one of the most common presentations of this parasitism is the biliary erratic ascariasis, which involves the biliary ways and the pancreatic conduit, although most of the research works report about the low incidence of this pathology in kids. In the present Article we report five cases of kids with a manifestation of ascariasis in common bile duct, four of them are the most interesting cases due to the presence of multiple biliary parasites. Once a revision made of paraclinical reports of these five cases and the characteristics of the E.R.C.P endoscopic procedure, we are showing the advantages of this method for the diagnostic and treatment of this pathology at the same time it is exposed to the readers a brief actualization of this infestations
[en] Ascariasis is one of the most common helminthic disease worldwide and evoked variable clinical manifestations by the migration of worm in the alimentary and biliary tract. The ultrasonographic detection of ascaris in the small bowel is relatively difficult, and no report on the ultrasonographic findings have been published in Korea. On abdominal ultrasonography, ascaris is seen as an intraluminal tubular structure with 4 linear echogenic stripes and movement. We report a case of ascaris in the small bowel detected by abdominal ultrasonography.
[en] We present a case of a woman who arrived with acute cholangitis symptomatology, and was diagnosed preoperatively by ultrasound as biliary ascariasis. During surgery, we extracted 32 worms of Ascaris lumbricoides from the Gallbladder and the common bile duct. Clinical outcome was successful, with out retention of worms
[en] In order to investigate the effect of UV radiation on the development of Ascaris lumbricoides larvae, eggs were exposed to increasing UV doses. Filtered wastewater from the secondary effluent taken from the Damascus wastewater treatment plant (DWTP) was used as irradiation and incubation medium. The progressive and accelerated embryonation stages were microscopically observed and the percentages of completely developed larvae were determined weekly. Results indicated that the UV radiation accelerated the development of larvae with increasing UV dose. Preliminary information about the relationship between the UV radiation dose and rate of embryonation is also presented
[en] A study was undertaken from January to June 2016 with the aim of characterizing the environmental forms of intestinal helminths that are present in some marshy areas in Yaounde. Monthly water samplings were carried out on eight different marshy areas which are: Bonamoussadi, Melen, Etoug-ebe, Mvog-betsi, Mokolo-elobie, Tsinga, Ekounou and Damas in the city of Yaounde. The observation of eggs and larvae of helminths was done using an inverted Olympus CK2 microscope with objective 40, after concentration of the samples, following the formol-ether concentration and/or Kato–Katz techniques. The hydrological and physicochemical assessment of the samples reveals a low oxygenation (20.93 ± 9.83%) and a high mineralization (566.16 ± 119.91 μS/cm) of these ecosystems. The biological analysis reveals the presence of eggs belonging to Ascaris sp., Enterobius sp., Ankylostomes sp., Trichostrongylus sp., Trichuris sp., Tænia sp., Hymenolepis nana, Hymenolepis diminuta, Diphyllobothrium sp., Fasciola sp., Schistosoma sp. and the larvae of Strongyloïdes sp. The statistical analysis presents a significant correlations to the threshold of 5% and 1% between the physicochemical and biological parameters quantified in our study.
[en] Aerobically-treated sewage sludge containing eggs of the nematode Ascaris suum was processed using accelerated electrons. After 8 weeks of incubation the morphological and developmental status of eggs was determined. Inhibition of development and the destruction of nematode embryos within eggs were observed at doses over 1.1 kGy. (author)
[en] The lethal gamma irradiation dose of ascaris lumbricoides which collected from Damascus Sewage water Plant was determined. Ascaris lumbricoides ova were treated with several gamma irradiation doses with (0.1, 0.2, 0.3, 0.4,...and 1.5 KGy). No morphological changes were observed on the eggs when directly examined microscopically after irradiation. However after two weeks of incubation at 37 degree centigrade the cell contents of the eggs which irradiated with 0.5 KGy and beyond were fragmented and scattered in the whole eggs and no larvae were observed after eight weeks of incubation. It is concluded that the dose 0.5 my be considered as the dose of choice if sewage water is to be treated by gamma rays. (author)
[en] We report the ultrasonographic findings of a 60 year old woman with pseudotumorous form of ascariasis. Real-time ultrasonographic examination using a curved array transducer revealed grossly thickened small bowel loops, multiple small circular deposits throughout the peritoneal cavity, and a moderate amount of ascites. The English literature on the different forms of abdominal ascariasis is reviewed. Specific signs, which include the 'strip' sign, the 'four-lines', 'inner tube', or 'double tube' sign, the 'bull's eye' or 'target' sign, a 'worm mass' or 'spaghetti-like' appearance, and the 'zig-zag' sign can be present in any form of abdominal ascariasis, as they represent the image of the Ascaris worms visualized under ultrasonographic examination. However, the non-specific signs are not peculiar to A. lumbricoides infections, but are results of secondary changes due to A. lumbricoides infections in the corresponding organs
