In this paper, I describe dividing practices in making up a specific medical-legal category-the revolving door patient-to identify, label, and direct the actions of particular people living with mental illness. The revolving door patient was a category that had been spoken of for some time, but became a formal legal subject with the introduction of the Alberta Mental Health Act 2010 and Community Treatment Orders (CTOs). I demonstrate how a rationale of control over unpredictable and dangerous individuals was primary in creating this new category, and that the characterization of the revolving door patient required a disciplinary technology to reduce danger...

PURPOSE: To determine and compare the repeatability of anterior corneal higher order aberrations (HOAs) using a Placido-based topographer (Allegro Topolyzer; WaveLight Technologie AG, Alcon Laboratories, Erlangen, Germany) in a sample of normal and keratoconic eyes. METHODS: Three repeated measurements of each cornea of normal and keratoconic eyes were taken with the Allegro Topolyzer. Repeatability of the HOAs (3rd- and 4th-order individual values and normalized polar Zernike coefficients, coma-like, root mean square (RMS) up to 8th-order values, HOA RMS, and total RMS for 6-mm pupil diameter) and central corneal power (3-mm pupil) were analyzed...

Die Diagnose von Hautkrankheiten beruht derzeit, über die klinische Beurteilung hinaus, hauptsächlich auf der Histologie. Hautbiopsien haben jedoch zahlreiche Nachteile, beispielsweise Schmerzen, Narbenbildung, Infektionsrisiko und Fehler bei der Probennahme. Mit den Fortschritten bezüglich dermatologischer Bildgebungstechnologien in jüngerer Zeit eröffneten sich klinische Anwendungsmöglichkeiten von Bildgebungsmethoden bei der Behandlung von Hautkrankheiten. Vor Kurzem wurde die hochauflösende optische Kohärenztomografie (HD-OCT) für die In-vivo-Anwendung entwickelt und kommerzialisiert (Skintell®; Agfa, Belgien)...

PURPOSE: To compare postoperative changes in apparent photopic and mesopic pupil size and centration in relation to cornea reflection landmarks after cataract surgery. SETTING: Clinical and Research Eye Institute, Athens, Greece. DESIGN: Prospective consecutive case study. METHODS: Pupils were imaged for pupil size and corneal vertex location before and 1-month after cataract surgery. Digital analysis of pupil images was used to determine the Cartesian coordinates (nasal-temporal, horizontal axis, superior-inferior, vertical axis) of the first Purkinje reflection point (approximating the corneal intersection of the visual axis [corneal vertex]) to the pupil geometric center (approximating the corneal intersection of the line of sight [corneal apex])...

The intrauterine insemination with husband's sperm is an assisted reproductive technologie, as proposed in the case of cervical infertility, moderate male infertility, dysovulation, mild or moderate endometriosis or unexplained infertility. In the last three indications the ovarian stimulation is necessary. The couple demographic criteria (age of both partners, lifestyle, duration of infertility) and the results of the infertility evaluation (ovarian reserve, uterus, spermogram-spermocytogram) increase the chances of pregnancy by intrauterine insemination with husband's sperm and reduce the risk of multiple pregnancies...

Barley samples (n = 128) from Central Canada (Manitoba) of the 1993 and 1994 crop years were analysed using enzyme immunoassays for the detection of the mycotoxins deoxy-nivalenol, 3-acetyldeoxynivalenol, 15-acetyldeoxynivalenol, and zearalenone. For this study enzyme immunoassays, which were developed at the Lehrstuhl für Hygiene und Technologie der Milch as well as a commercial testkit (Ridascreen® DON, specific for deoxynivalenol and its acetylated derivatives) were used. In addition, some samples were analysed by using a combination of HPLC and enzyme immunoassay (immunochromatography)...

STUDY QUESTION: What are the aneuploidy rates and incidence of mosaicism in good-quality human preimplantation embryos. SUMMARY ANSWER: High-level mosaicism and structural aberrations are not restricted to arrested or poorly developing embryos but are also common in good-quality IVF embryos. WHAT IS KNOWN ALREADY: Humans, compared with other mammals, have a poor fertility rate, and even IVF treatments have a relatively low success rate. It is known that human gametes and early preimplantation embryos carry chromosomal abnormalities that are thought to lower their developmental potential...

The phenomenon of cognitive enhancement is attracting attention in bioethics literature and beyond, in public policy. In response, three bodies--the British Medical Association (BMA); the Commission de l'éthique de la Science et de la technologie (CEST) du Québec; the American Academy of Neurology (AAN)--have produced reports and guidance on this topic. To gain insights into different public policy approaches, rationales, and recommendations on the topic, we analyzed these reports in depth. We found convergence on the definition (with the exception of the CEST) of cognitive enhancement...
