This case series describes acute corneal hydrops in three young horses. Due to similarities in the clinical appearance and progression of the disease with that which is reported in humans and cats with acute corneal hydrops, traumatic Descemet's membrane rupture was suspected to be the underlying aetiology in these equine cases. The horses presented with acute severe corneal oedema with intrastromal bullae formation and anterior bulging of the corneal contour. Focal posterior corneal changes were also seen in two of three cases. Mild anterior uveitis was also present. Other causes of corneal oedema (e.g. glaucoma) were ruled out based on presentation and clinical examination. Treatment approaches were medical and included various combinations of prophylactic topical antimicrobial therapy in case of secondary corneal ulceration, anti-inflammatory therapy for uveitis, targeted oedema therapy with topical hypertonic saline and corneal cross-linking, and placement of a temporary partial tarsorrhaphy for corneal tamponade. The outcome was excellent in all cases, with rapid resolution of the ocular changes. Acute corneal hydrops of presumed traumatic Descemet's membrane rupture origin should be considered in cases of young horses presenting with acute corneal oedema. However, further studies are warranted to better characterise the disease and to try to confirm the suspected aetiology.

This paper describes the development of a studio-based approach for teaching ergonomics and human factors to undergraduate engineering students. Studio-based methods in engineering education draw on the concept of a “design studio” as the basis for learning and applying fundamental skills and knowledge through a series of directed exploration and design projects under the guidance of the course instructor. The use of these methods for teaching foundational courses in ergonomics and human factors is especially promising, as laboratory experiences and design projects are often an integral part of the course.

The goal of human-centered product design is to create products that are useful, usable, and desirable. For many years, human factors has been about research, modeling, and evaluating the functional usefulness and usability of products and systems. In recent years, however, the role of emotion in product design has become a ‘hot topic’ for human factors professionals, and a variety of methods have been developed for identifying emotional needs and the emotional response people have to products. In this paper, a preliminary study aimed at developing an integrated understanding of the functional and emotional aspects of user experience with cell phones is discussed. A variety of techniques were employed and the combined data analyzed to develop a holistic picture of the user experience. We anticipate that the results of the study will serve as ‘proof of concept’ for future development work.

The time taken by nurses to prepare and administer insulin was lower with the pen device compared with vial and syringe. Furthermore, areas were identified for potential nursing education to enhance safe and appropriate use of insulin with both delivery methods.
