Orbital cysts are rare and, clinically, often present diagnostic problems.The following case with bilateral giant orbital cysts is presented because no similar case can be found in the literature

Feasibility of transapical aortic valve replacement through a left ventricular apical diverticulum.

ABSTRACT: Transapical aortic valve replacement is an established technique performed in high-risk patients with symptomatic aortic valve stenosis and vascular disease contraindicating trans-vascular and trans-aortic procedures. The presence of a left ventricular apical diverticulum is a rare event and the treatment depends on dimensions and estimated risk of embolisation, rupture, or onset of ventricular arrhythmias. The diagnosis is based on standard cardiac imaging and symptoms are very rare. In this case report we illustrate our experience with a 81 years old female patient suffering from symptomatic aortic valve stenosis, respiratory disease, chronic renal failure and severe peripheral vascular disease (logistic euroscore: 42%), who successfully underwent a transapical 23 mm balloon-expandable stent-valve implantation through an apical diverticulum of the left ventricle. Intra-luminal thrombi were absent and during the same procedure were able to treat the valve disease and to successfully exclude the apical diverticulum without complications and through a mini thoracotomy. To the best of our knowledge, this is the first time that a transapical procedure is successfully performed through an apical diverticulum

Management development: a literature review and implications for future research – Part I: Conceptualisations and Practices

Interest in management development is mushrooming. The number of articles which address different aspects of it are likewise increasing apace. This has heightened the need for a broad-based review which will pull the material together, give shape to it, evaluate it and draw out its implications. In this, the first of a two-part article, this task is commenced

Beyond rigour and relevance: A critical realist approach to business education

This article takes a critical realist perspective to understand the research—practice gap in the field of business and management. To investigate issues surrounding the rigour versus relevance debate, we examine how the divergent perspectives of scholars and practitioners can be bridged by a critical realist approach in relation to: (1) the research paradigm: instead of confining their research within methodological purism, scholars may need to deploy any research paradigm to investigate a phenomenon in its context, (2) context and causality: critical realism provides an ontological grounding for interpretivist research reaffirming the importance of a focus on context, meaning and interpretation as causal influences, (3) methodological rigidity: multiple research methods will be more important when addressing research—practice gaps since they are more receptive to interdisciplinary functions and contexts in time and space than traditional methodologies, and (4) ethical aspects of business research highlighting the need to engage with the knowledge agenda of not only the university but also society overall. The critical nature of management studies we contend also helps to explain why at least certain research—practice gaps can be treated as natural because of divergent preferences of scholars and practitioners
