Abstract Casestudy: Hydatid cyst results when humans get infected by ingesting the eggs of Echinococcus Granulosus. Upon release, the six-hooked oncospheres penetrate the intestinal wall and migrate via circulation to various organs, mostly liver and lung. Here, they develop into hydatid cyst. The cyst enlarges gradually and is filled with daughter cysts and protoscolices. We report the case of a 69-year old female, native of Uzbekistan, who presented with right upper quadrant pain. Imaging showed a 20 cm liver cyst and multiple pelvic cysts with a stage of CE2 implying that they were most likely functional. Serum Echinococcal antibody was positive. After 2 months of Albendazole treatment, there was no radiological change. The patient underwent laparoscopic puncture aspiration and injection with 20% saline (PAIR) and pericystectomy of the pelvic cysts. The aspirate revealed scattered scolices, inflammatory cells and abundant amorphous debris consistent with hydatid cyst. Bilateral 5-cm pelvic cysts had pale yellow, soft to firm walled, multiple cavities. Microscopy revealed a fibrofatty outermost layer with chronic inflammation and a two-layered cyst wall including a thin germinal epithelium covered by a thick acellular outer membrane. Multiple parasites, some degenerate (dense eosinophilic) were present, confirming the cytologic diagnosis of cystic echinococcosis. Following further treatment with Albendazole, she underwent a robotic assisted PAIR and partial peri-cystectomy of the liver cyst with repair of the duct to cyst communication. The liver cyst contained daughter cysts of Echinococcus and brood capsule with protoscolices. After 2 months more of Albendazole her Elisa was intermediate. A prior study reported cytopathologic diagnosis of hydatid cyst in 17 patients evaluated for various masses. Our case highlights the role of cytology sampling in confirming the diagnosis of hydatid disease. Potentially fatal in untreated patients, this entity has to be considered in the differential diagnosis of cystic lesions.

Native Host

The island marble butterfly (Euchloe ausonides insulanus), thought to be extinct throughout the 20th century until re-discovered on a single remote island in Puget Sound in 1998, has become the focus of a concerted protection effort to prevent its extinction. However, efforts to “restore” island marble habitat conflict with efforts to “restore” the prairie ecosystem where it lives, because of the butterfly’s use of a non-native “weedy” host plant. Through a case study of the island marble project, we examine the practice of ecological restoration as the enactment of particular norms that define which species are understood to belong in the place being restored. We contextualize this case study within ongoing debates over the value of “native” species, indicative of deep-seated uncertainties and anxieties about the role of human intervention to alter or manage landscapes and ecosystems, in the time commonly described as the “Anthropocene.” We interpret the question of “what plants and animals belong in a particular place?” as not a question of scientific truth, but a value-laden construct of environmental management in practice, and we argue for deeper reflexivity on the part of environmental scientists and managers about the social values that inform ecological restoration.

Abstract In the following article we try to re-evaluate, the place drama occupies in contemporary elementary education. By limiting the role of drama to literature studies and theatre productions, we lose a greater potential Theatre Pedagogy has to offer to a much broader educational spectrum. The participatory practices of Theatre and Drama in Education (TiE, DiE) promote active learning, based on a most organic children’s activity - play. While students co-create the fictional world of drama, teacher's guidance is crucial in setting new challenges, encouraging students to find creative solutions and reflect on often-complex social issues. Because of its art component, drama challenges the participants on a cognitive as well as emotional level, becoming a truly transformational experience. As such, Drama in Education is especially useful when approaching sensitive and controversial topics. This thesis is presented on a case study observing Year 6 students at St’ Michael’s CE Academy in Birmingham, UK, using Drama in Education method as part of History curriculum.
