“…The terms "toxocar*", "nematode ophthalmitis", "visceral larva migrans", "ocular larva migrans", "Nematode endophthalmitis", "dog roundworm" and "cat roundworm" were used as keywords to search titles. These keywords were based on previous review articles [6,[29][30][31]. The asterisk (*) was applied as a wildcard and enabled the search for variations of key terms.…”

“…Toxocara specimens were first illustrated by Werner in 1782; however, the genus was not recognized until 1905 by Stiles [5]. The clinical symptoms of toxocariasis in humans may vary from asymptomatic infection to localized symptoms (ocular and neurological) or severe systemic infection (visceral larva migrans), which is commonly complicated by blood eosinophilia [6][7][8].…”

BackgroundToxocariasis is a highly prevalent parasitic disease in the tropical regions of the world, with its impact on public health being typically underestimated. To better recognise the trends and characteristics of toxocariasis research, this study is a bibliometric analysis of the global toxocariasis research.MethodsSearches were completed on April 5, 2016, using the Scopus database. A search without any language restriction was performed to extract publications dealing with toxocariasis. Terms related to toxocariasis were used to perform a title keyword search.ResultsA total of 2765 publications comprising 11 document types and published between 1932 and 2015 were included in the analysis. Articles were the most popular document form, accounting for 83.62% of all publications, followed by letters (3.80%) and reviews (3.4%). The annual number of research publications increased from 30 in 1980 to 111 in 2015, indicating that the number of publications on toxocariasis has increased slowly over the past 35 years. The United States of America and Japan are the predominant countries of origin, with 303 articles and 207 articles, respectively, followed by Brazil and the United Kingdom, with 180 (6.5%) each. The h-index for all the publications was 60. The highest h-index were for publications from the United Kingdom (h-index value = 43) and the United States (h-index value = 39); these two countries were also involved with the highest number of international collaborations, with 27 and 28 countries, respectively.ConclusionsDeveloped countries, including the United States, Japan, the United Kingdom, France, Germany and Italy, are the world’s leaders in toxocariasis research, contributing to more than 34% of the total published literature. In addition, developing countries, such as Brazil, Poland, Argentina and India, showed a noticeable increase in published papers on toxocariasis research in recent years. A push for more collaboration is needed to achieve a superior research strategy related to toxocariasis at the global level from the viewpoint of epidemiological data, clinical aspects, medical ecology, molecular aspects and treatment practices associated with toxocariasis.

“…Furthermore, a rare but likely life-threatening disorder caused by toxocariasis is cardiac involvement that evokes inflammation of heart tissues, tamponade and heart failure. [12][13][14][15] Infection with Toxocara species has global distribution and is taken into account as one of the most frequent helminthiases in humans, according to seroprevalence reports. 1,8 Histopathological examinations as well as several medical imaging techniques, e.g.…”

Toxocariasis is a zoonotic and widespread infection which manifest as a spectrum of syndromes in humans such as visceral, neural, ocular, covert and asymptomatic. Herein we aimed to design a systematic review and meta-analysis to determine the prevalence of Toxocara spp. eggs in soil depositories in Iran. English (PubMed, Scopus, Google Scholar, Web of Science, Science Direct, EBSCO, and Ovid) and Persian (Scientific Information Database and Magiran) databases were explored. This review resulted in a total of 14 publications meeting the inclusion criteria during January 2000-November 2016. Altogether, 3031 soil samples were examined among which 470 were positive in terms of Toxocara spp. The weighted overall prevalence of Toxocara spp. in soil samples was 16% (95% CI = 11-21%), and Tehran and Qazvin provinces had the highest and lowest prevalence rates, respectively. Metaregression analysis showed that the correlation between prevalence of Toxocara eggs in soil with sample size (P = 0.45) and year of study (P = 0.42) were not statistically significant. Further studies are highly recommended to enlighten different aspects of toxocariasis in Iran.

“…Most infected humans are asymptomatic, but fever, hepatosplenomegaly, gastrointestinal, respiratory, neurological, and ocular symptoms or allergic reactions can occur [1, 2]. Clinically relevant cardiac manifestations, even though rare in humans, include myocarditis, pericarditis, Loeffler's endocarditis, and combinations of these [3]. The diagnosis is usually based on clinical symptoms, eosinophilia and serological titers.…”
