Adult Tapeworm

AbstractCanine echinococcosis is caused by the adult tapeworm of Echinococcus granulosus. As intermediate hosts, humans and livestock become infected following ingestion of eggs that are passed in the faeces of dogs. Mature eggs develop into hydatid cysts in different organs, leading to hydatid disease, which is a serious public health problem. In the present study, we investigated the proportion of mature eggs of E. granulosus in 140 dogs from three regions of Tunisia. The results showed the predominance of immature E. granulosus eggs in infected dogs and the occurrence of a small proportion of oncospheres. The ability of immature eggs to infect humans and livestock is discussed.

Abattoir Data

AbstractIn a survey carried out in 1991–1992 in the town of Yirka in Northern Israel, 49 dogs were examined for Echinococcus granulosus infection and abattoir data, based on organs condemned for the presence of parasites, was collected. The presence of E. granulosus by arecoline test was demonstrated in 7 (14.2%) of the dogs examined, but no parasites were found in the intestines of five stray dogs shot in the area. A survey of sheep slaughtered in the local abattoir during a one-month period revealed Echinococcus cysts in 10% of the 255 animals examined. No Echinococcus parasites were detected in 21 dogs examined 3 months after the initiation of praziquantel treatment. Echinococcosis seems to be a very serious public health problem in Israel and a control programme needs to be given a high priority.

Helminth Infections

Globally, stray dogs have been a major source of zoonoses such as cutaneous larval migrans, visceral larval migrans and hydatidosis. These dogs are recognized as being a major public health problem where their population is unchecked. This study was conducted to determine the prevalence of intestinal helminth parasites of stray dogs in Lagos metropolis. Stools of 96 stray dogs were examined microscopically for ova of these parasites using centrifugation flotation method. Four species of intestinal helminths were identified. The overall prevalence of helminths infection was 61.4%, with Ancylostoma caninum having a prevalence of 62.5%, Toxocara canis 20.8%, Dipylidium caninum 18.7% and Strongyloides stercoralis 2.0%. T. canis had the highest worm burden of 1,250 egg per gram (EPG) while S. stercoralis had the least (100 EPG). The areas with the most helminth infections were Yaba (n=12, X̄=1.58, SD=0.793), Agege (n=11, X̄=1.73, SD=0.786) and Ikotun (n=11, X̄=1.45, SD=0.820). S. stercoralis was only found in samples obtained from Mushin and Ikorodu. Most of the stool samples obtained from this study had mixed infections, 83.3% were infected with three helminth species, 8.3% were infected with four helminth species and none had double infection. Mushin had the most mixed infections (n=4, X̄=1.900, SD=1.101) while Obalende had the least (n=1, X̄=1.000, SD=0.000). Most of the intestinal helminth parasites identified in this study are zoonotic and thus pose a public health problem. Environmental factors seem to influence the health condition of these dogs, thus concerted efforts should be made to reduce the growing population of stray dogs on the street of Lagos.

Abstract Echinococcus granulosus, a zoonotic tapeworm with a dog-herbivore life cycle, is known to use ruminants, horses, pigs, etc., as intermediate hosts. Natural infections of hydatid cysts have not been documented in small animals like rabbits in India. This paper records spontaneous intrathoracic, extrapulmonary hydatid cysts of E. granulosus in a cage reared rabbit. The presence of non-invasive unilocular cyst with typical protoscolices containing rostellar hooks favoured the diagnosis of E. granulosus over E. multilocularis, the only other Echinococcus species found in India. The presence of fertile hydatid cyst points to the fact that rabbits can also act as natural intermediate hosts for E. granulosus. The significance of the findings in relation to public health importance is discussed.

Uncommon Location

The hydatid cyst is a parasitic pathology which is endemic in Tunisia and presents a public health problem. Hydatid cysts located in the retroperitoneum, especially around or in the kidney, are rare and only represent 5% of visceral locations. The kidney is the most commonly affected organ of the urinary tract. The psoas muscle is an uncommon location and not less than 70 cases have been cited. We report the case of an unusual presentation of a right kidney hydatid cyst associated with a psoas muscle location. To our knowledge, this association of double retroperitoneal location has not been reported in the literature.

Clinical Dilemma

This article aims to compare available treatment options for type III liver hydatid cysts, including surgery and percutaneous techniques. Hydatid disease is a helminthic infection caused by Echinococcus granulosus and is a serious public health problem in endemic regions of the world. Hydatid cyst of the liver is the most common clinical presentation of Echinococcus granulosus. According to Gharbi classification, hydatid cysts of the liver are classified into 5 types. Type III hydatid cysts are those with fluid collection and septa. Treatment of Gharbi type III hydatid cysts is still controversial. Some researchers think that Gharbi type III hydatid cysts are not suitable for percutaneous drainage, and surgery is the suitable treatment option. There are not enough prospective studies comparing percutaneous and surgical techniques for the treatment of type III hydatid disease of the liver. A proper meta-analysis does not seem to be possible with the available studies in current medical literature.

Nachhaltige Entwicklung

Zusammenfassung. Kindesmisshandlung stellt einen bedeutenden Risikofaktor für die Entwicklung dar. Einzelne Formen von Kindesmisshandlung treten häufig nicht isoliert auf, sondern das gemeinsame Auftreten verschiedener Formen von Kindesmisshandlung stellt eher die Regel als die Ausnahme dar. Neben den langfristigen und vielfältigen individuellen Folgen führt Kindesmisshandlung jährlich zu einer hohen gesamtgesellschaftlichen Belastung. Die WHO hat Kindesmisshandlung als großes Public Health Problem identifiziert und die Vereinten Nationen haben den Kampf gegen Kindesmisshandlung zum Ziel in ihrer Agenda für nachhaltige Entwicklung gemacht. In dem vorliegenden Beitrag werden die Häufigkeit sowie das gemeinsame Auftreten unterschiedlicher Formen von Kindesmisshandlung sowie deren Assoziation mit psychischen und somatischen Folgen auf Basis einer bevölkerungsrepräsentativen Stichprobe untersucht und dargestellt. Die Ergebnisse verdeutlichen den Zusammenhang zwischen der Kumulation verschiedener Formen von Misshandlung und negativen Folgen für die Betroffenen. So ist das Risiko für negative Konsequenzen beim Erleben von vier oder mehr Formen von Misshandlung um das bis zu 10-fache erhöht. Viel zu selten werden die kumulativen Effekte von mehreren Belastungen berücksichtigt. Gerade weil die Wirkweisen über die Misshandlung, die Gesundheit beeinflusst, zunehmend gut untersucht sind, muss dieses Wissen im Gesundheitswesen stärker bei der Konzeption von Präventions- und Interventionsmaßnahmen berücksichtigt werden.
