Macroscopic optical imaging has rather humble technical origins; it has been mostly implemented by photographic means using appropriate filters, a light source and a camera yielding images of tissues. This approach relates to human vision and perception, and is simple to implement and use. Therefore, it has found wide acceptance, especially in recording fluorescence and bioluminescence signals. Yet, the difficulty in resolving depth and the dependence of the light intensity recorded on tissue optical properties may compromise the accuracy of the approach. Recently, optical technology has seen significant advances that bring a new performance level in optical investigations. Quantitative real-time multi-spectral optical and optoacoustic (photoacoustic) methods enable high-resolution quantitative imaging of tissue and disease biomarkers and can significantly enhance medical vision in diagnostic or interventional procedures such as dermatology, endoscopy, surgery, and various vascular and intravascular imaging applications. This performance is showcased herein and examples are given to illustrate how it is possible to shift the paradigm of optical clinical translation.

Medical Vision

IN 1856, WHEN MANY VICTORIAN PHYSICIANS WERE STRUGGLING TO DEFINE A MODEL OF CLINICAL MEDICINE, the reviewer of one collection of case histories voiced his dismay at the physician-author's preference for “dreadful incidents” and “cases exceptional and strange” (“Works” 473). Indeed, although physicians of the clinical era did not disguise their efforts to achieve a new kind of discourse, productive of a “realist” vision, few acknowledge how often the “clinical” case history of the nineteenth century also shares the romantic discourse of the Gothic, especially its interest in the supernatural and the unexplainable and its narrative aim of arousing suspense, horror, and astonishment in the reader. Literary critics have also focused primarily on the association of medical narrative with a realist literary discourse. Nineteenth-century physicians did campaign for the formal, objective, and professional clinical discourse that serves as their contribution to a realist aesthetic, in the process explicitly rejecting eighteenth-century medicine's fascination with “the curious” and its subterranean affiliation with the unknown, the unexplainable, and the subjective. But, as I show in this article, a discourse of “the curious,” allied with a Gothic literary aesthetic, stubbornly remained a critical element of many case histories, though it often presented under the mask of the more acceptable term, “interesting.” The discourse of Gothic romance in the case history provides a narrative frame that, unlike the essentially realist clinical discourse, could make sense of the physician's curious gaze, which had become nearly unrecognizable as a specifically medical vision. Indeed, a “curious” medical discourse haunts even case histories of the high clinical era, late in the century; and it energizes the nineteenth-century Gothic novel. Samuel Warren's novelPassages from the Diary of a Late Physician–deplored in the quotation above–illuminates this tradition of “Gothic medicine” as it plays out in the nineteenth-century novel. This tradition, I argue, provides the novel with a powerful model of cultural contamination and conflict in its yoking of disparate discourses. Gothic medicine demonstrates the importance of clinical medicine to literary romance, and it cannot help but reveal the ghost of “the curious” in the clinic.

Stereo Acuity

Visual standards for military aviators were historically set in the 1920s with requirements based on the visual systems of aircraft at the time, and these standards have changed very little despite significant advances in aircraft technology. Helmet-mounted displays (HMDs) today enable pilots to keep their head out of the cockpit while flying and can be monocular, biocular or binocular in design. With next generation binocular HMDs, flight data can be displayed in three-dimensional stereo to declutter information presented, improving search times and potentially improve overall performance further. However, these new visually demanding technologies place previously unconsidered stresses on the human visual system. As such, new medical vision standards may be required for military aircrew along with improved testing methods to accurately characterise stereo acuity.

ObjectivesPeople with Down syndrome (DS) are at high risk for developing dementia and early diagnosis is vital in enhancing quality of life. Our aim was to compare our practice to consensus recommendations on evaluation, diagnosis and pharmacological treatment of individuals with DS who develop dementia. We also aimed to establish the average time taken to make a diagnosis of dementia and to commence pharmacotherapy, and to assess tolerability to acetylcholinesterase inhibitors.MethodsRetrospective chart review in an exhaustive sample containing all current service users attending our service with DS and a diagnosis of dementia (n=20).ResultsThe sample was 75% female and 70% had a moderate intellectual disability. The average age at diagnosis of dementia was 52.42 years old. The average time to diagnosis from first symptom was 1.13 years and the average time to commence pharmacotherapy was 0.23 years. A total of 17 patients commenced on acetylcholinesterase inhibitors, and of these seven discontinued medication due to side-effects or lack of efficacy.ConclusionsThe results on anticholinesterases add to the limited pool of data on treatment of dementia in DS. There was an identified need to improve the rates of medical, vision and hearing assessments, and prospective screening. Deficiencies in screening and diagnosis may be addressed by implementing a standardised dementia assessment pathway to include prospective screening and longitudinal assessment using easily administered scales. We highlight the importance of improving the diagnostic process, as a vital window of opportunity to commence a comprehensive care plan may be lost.

The literature on the activities of medical professionals during the tumultuous years of the Third Reich has, over the last decade, increased substantially. However, many questions remain unanswered and the subject is likely to receive further attention following recent access to previously restricted archival material in Eastern Europe. In this paper, based on the English language literature, the author explores the role of medicine, and in particular psychiatry, in defining the bio-medical vision that was central to Nazi ideology.

Massive Development

The application of information technology is rapidly utilized in the medical system. There is also a massive development in the automatic method for recognizing and detecting objects in the real world. In this study, we present a system called Medical Vision which is designed for people who has no expertise in medical. Medical Vision is a web and mobile-based application to give an initial knowledge in a medical image. This system has 5 features; object detection, web detection, object labeling, safe search, and image properties. These features are run by embedding Google Vision API in the system. We evaluate this system by observing the result of some medical images which inputted into the system. The results showed that our system presents a promising performance and able to give relevant information related to the given image.
