A parasitic nematode from the stomach of Japanese eel Anguilla japonica Temminck et Schlegel in western Japan, previously identified as Heliconema longissimum (Ortlepp, 1922), was morphologically re-examined and compared with the previous descriptions. In addition, the third-stage larva of this nematode is described, based on the specimens of encapsuled larvae found in musculature of two crabs, Hemigrapsus sp. and Perisesarma bidens (De Haan), caught from the upper-intertidal zone of the same locality. As a result of the morphological observation, seven pairs of postcloacal papillae in adult males are confirmed. This matches with the character of H. longissimum, but the shape of the fifth postcloacal papillae differs between the present material and H. longissimum; the former possesses pedunculate papillae in the fifth pair whereas the latter has sessile papillae. Since the pedunculate papillae can be found in the original description and the syntype specimens of H. anguillae Yamaguti, 1935 that has been synonymised with H. longissimum, we thus here resurrect H. anguillae as an accepted species. For the life-cycle of the present nematode, littoral crabs, including the two infected species, are likely to be the source of infections for Japanese eels, acting as intermediate hosts., Hirotaka Katahira, Kazuya Nagasawa., and Obsahuje bibliografii
The present study is the first survey on the role of Artemia franciscana Kellogg as intermediate host of helminth parasites in its native geographical range in North America (previous studies have recorded nine cestode and one nematode species from this host in its invasive habitats in the Western Mediterranean). Samples of Artemia franciscana were collected from four sites in the Great Salt Lake (GSL), Utah, across several months (June-September 2009). A. franciscana serves as intermediate host of five helminth species in this lake. Four of them are cestodes: three hymenolepidids, i.e. Confluaria podicipina (Szymanski, 1905) (adults parasitic in grebes), Hymenolepis (sensu lato) californicus Young, 1950 (adults parasitic in gulls), Wardium sp. (definitive host unknown, probably charadriiform birds), and one dilepidid, Fuhrmannolepis averini Spassky et Yurpalova, 1967 (adults parasitic in phalaropes). In addition, an unidentified nematode of the family Acuariidae was recorded. Confluaria podicipina is the most prevalent and abundant parasite at all sampling sites, followed by H. (s. l.) californicus. The species composition of the parasites and the spatial variations in their prevalence and abundance reflect the abundance and distribution of aquatic birds serving as their definitive hosts. The temporal dynamics of the overall helminth infections exhibits the highest prevalence in the last month of study at each site (August or September). This native population of A. franciscana from GSL is characterised with higher prevalence, intensity and abundance of the overall cestode infection compared to the introduced populations of this species in the Palaearctic Region. The values of the infection descriptors in the native population of A. franciscana are slightly lower or in some cases similar to those of the Palaearctic species Artemia parthenogenetica Barigozzi (diploid populations) and Artemia salina (Linnaeus) in their native habitats., Stella Redón, Nicole J.

Infantilní hemangiomy jsou nejčastějšími benigními vaskulárními nádory novorozeneckého a kojeneckého věku. Jedná se o nádory s velmi dobrou prognózou. Většina infantilních hemangiomů spontánně zcela regreduje v prvních deseti letech života. Jen deset procent infantilních hemangiomů vyžaduje nějakou terapii. V současné době je preferováno použití b-blokátoru propranololu. Ostatní typy benigních cévních nádorů je zapotřebí diferenciálně diagnosticky odlišit pro zahájení vhodné terapie a určení prognózy. Předložený článek shrnuje základní poznatky o hemangiomech u novorozenců. V závěru článku je zmíněna krátká kazuistika, kdy byla léčba rozsáhlého hemangiomu zahajována po konzultacích na našem pracovišti za kontroly kardiology., Infantile hemangiomas are the most common benign vascular tumors of neonatal and infancy. These are tumors with a good prognosis. Most infantile hemangiomas spontaneously regress completely in the first decade of life. Only ten percent of infantile hemangiomas require some therapy. Currently it is preferred to use b-blocker propranolol. Other types of benign vascular tumors are needed to distinguish the differential diagnosis for initiation of appropriate therapy and prognosis. The present article summarizes the main findings of hemangiomas in infants. In conclusion, the article mentions a short case study, in which treatment was initiated extensive hemangioma after consultations at our clinic for checks cardiologists., Martin Pánek, and Literatura
