Voiding urosonography with ultrasound contrast agents for the diagnosis of vesicoureteric reflux in children: I. Procedure
Voiding urosonography (VUS) encompasses examination of the urinary tract with intravesical administration of US contrast agent (UCA) for diagnosis of vesicoureteric reflux (VUR). The real breakthrough for US examination of VUR came with the availability of stabilized UCAs in the mid-1990s. This article presents a comprehensive review of various procedural aspects of VUS. Different US modalities are available for detecting the echogenic microbubbles: fundamental mode, colour Doppler US, harmonic imaging and dedicated contrast imaging with multiple display options. The reflux is graded (1 to 5) in a similar manner to the system used in voiding cystourethrography (VCUG). The most commonly used UCA for VUS, Levovist, is galactose-based and contains air-filled microbubbles. The recommended concentration is 300 mg/ml at a dose of 5–10%, or less than 5%, of the bladder filling volume when using fundamental or harmonic imaging modes, respectively. There are preliminary reports of VUS using a second-generation UCA, SonoVue. Here the UCA volume is less than 1% of the bladder filling volume. There is no specific contraindication to intravesical administration of UCA. The safety profile of intravesical Levovist is very high with no reports of side effects over a decade of use in VUS

The Many Virtues of Second Nature : Habitus in Latin Medieval Philosophy
This chapter consists of a systematic introduction to the nature and function of habitus in Latin medieval philosophy. Over the course of this introduction, several topics are treated: the theoretical necessity to posit habitus; their nature; their causal contribution to the production of internal and external acts; how and why habitus can grow and decay; what makes their unity when they can have multiple objects and work in clusters. Finally we examine two specific questions: why intellectual habitus represent a special case that triggered considerable debate; how human beings can be said to be free if their actions are determined by moral habitus

Hepatobiliary and pancreatic imaging in children—techniques and an overview of non-neoplastic disease entities
Imaging plays a major role in the diagnostic work-up of children with hepatobiliary or pancreatic diseases. It consists mainly of US, CT and MRI, with US and MRI being the preferred imaging modalities because of the lack of ionizing radiation. In this review the technique of US, CT and MRI in children will be addressed, followed by a comprehensive overview of the imaging characteristics of several hepatobiliary and pancreatic disease entities most common in the paediatric age group
The reactions of Bahir Dar University students to moral dilemmas related to corruction: implications for moral education programmes
This study aimed at examining moral reasoning related to corruption. Data were obtained from 350 purposively selected Bahir Dar University students (175 males and 175 females) using moral reasoning questionnaire. Using Kohlberg's theory of moral development and Gilligan's moral orientation model, the moral reasoning questionnaire was scored for moral stage and moral orientation. Results in multiple-regression analysis indicated that the old age group (22-26 yeas) had significantly higher stage of moral reasoning than the young age group (18-21 years) when responding to moral dilemmas about issues of corruption. But, there was no significant age group difference with respect to moral orientation. Furthermore, there was no gender difference in stage of moral reasoning and moral orientation. The importance of the results, particularly the educational implications, for understanding the role of psychological intervention programmes and commitments in combating corruption are discussed.
