Cystic hydatidosis (CH) is a worldwide distributed parasitic zoonosis. It is considered one of the 17 neglected parasitic tropical diseases, among cysticercosis and soil transmitted helminthiases. CH is caused by the larval stage of Echinococcus granulosus, a tapeworm that usually infects dogs and other carnivorous animals as definitive hosts and herbivorous animals and rarely humans as intermediate hosts. Main primary localizations are the liver and the lung. In less than 3% they can primarily be present in the spleen. Treatment is mainly surgical, in some cases resulting in reoccurrence. In this paper we present the case of a male 55 years old patient who underwent a surgical intervention on his spleen for a solitary hydatid cyst as primary localization. Fifteen years after the operation the patient presented macroscopic haematuria; routine laboratory findings presented soft eosinophilia, 5%, without any other modification. There was found no palpable tumour in the pelvis by rectal examination. Abdominal ultrasound investigation revealed a 2×1 cm formation in the urinary bladder at the base of the left bladder-wall and a retrovesical, inhomogeneous 10×10 cm tumour with multiple septa and transonic zones. Computed tomography (CT) scan strongly suggested the presence of a bladder tumour and a hydatid cyst. The symptoms caused by the bladder tumour revealed the co-existing non-symptomatic retrovesical secondary CH, which is a rare complication of splenic Echinococcus granulosus infection. Close follow-up and a proper pre- and postoperative anti-parasitic medication of the patient could have prevented reoccurrence of CH.

Background and aims

Even the richest statistical databases leave the reasons of student dropout from higher education largely obscure. It is the answers of the students who drop out that the panel examinations of the cohorts of students do not contain. The theoretical background to our research was provided by Coleman’s concept of social capital (1961), Tinto’s integrational and Astin’s involvement theory, as well as Pascarella and Terenzini’s institutional integration/embeddedness ideas (2005).


To find a solution to that problem, we devised a quantitative, questionnaire survey, based upon the qualitative examination of students who have dropped out (DEPART 2018; N = 591). For data gathering, the snowball method was used, and almost all academic fields are represented in the database. The primary objective of the research was revealing and identifying the factors preventing students from obtaining a degree, surveying the processes and decisions that resulted in their not being able to graduate. School career, educational experience, the attitude of the family to the student’s studies, job/career orientation, educational and social experience in higher education, competitive activities, and social–economical characteristics were the topics we examined. We collected the data of the students who have dropped out with the questionnaire (IESA 2015; N = 2017) and compared the information thus collected with the social and demographic characteristics, school career, and higher educational integration of persistent students. We also compared the data to the embeddedness of (the persistent) students in various voluntary organizations (civic, sport, and religious). For the examination of persistence, a 9-item, highly reliable scale [Cronbach, 883 (IESA)] has been used since 2012.


The results suggest that the influence of institutional factors and that of the social network is more powerful than the individual characteristics. We found considerable differences between the intra- and extra-campus influences.


Our findings highlight the necessity of providing empirical foundations for the institutional dropout prevention programs.
