Neuroprosthetics 2.0
(2019)
This book, now in its second, completely revised and updated edition, offers a critical approach to the challenging interpretation of the latest research data obtained using functional neuroimaging in whiplash injury. Such a comprehensive guide to recent and current international research in the field is more necessary than ever, given that the confusion regarding the condition and the medicolegal discussions surrounding it have increased further despite the publication of much literature on the subject. In recent decades especially the functional imaging methods – such as single-photon emission tomography, positron emission tomography, functional MRI, and hybrid techniques – have demonstrated a variety of significant brain alterations. Functional Neuroimaging in Whiplash Injury - New Approaches covers all aspects, including the imaging tools themselves, the various methods of image analysis, different atlas systems, and diagnostic and clinical aspects. The book will help physicians, patients and their relatives and friends, and others to understand this condition as a disease.
In this paper pathophysiological interrelated deactivation/activation phenomena are set out in the example of whiplash injury. These phenomena could have been underestimated in previous positron emission tomography studies as their focus was on hypoperfusion rather than hyperperfusion. In addition, statistical parametric mapping analysis of cerebral studies is normally not fine-tuned to special interesting areas rather than to obvious clusters of difference.
Hatte Maria einen Jodmangel?
(2019)
Auch wenn sie im Internet-Zeitalter zu einer Normalität werden, bleiben Ferndiagnosen unter Medizinern umstritten. Erst recht vorsichtig sollte man sein, wenn es sich bei dem Patienten um die leibliche Mutter Gottes handelt. Doch wenn man in diesem Gemälde eine authentische Dokumentation sieht, ist der Befund eindeutig: Maria hatte zum Zeitpunkt der Geburt ihres berühmten Sohns auffällig lange und schlanke Finger sowie eine Struma des Grads II bis III.
The Baroque composer Johann Sebastian Bach (1685–1750) has left us with many puzzles. The well-known oil painting by Elias Gottlob Haußmann is the only painting for which Bach actually posed in person. According to this portrait, Bach must have been quite obese. The cheeks and nose are flushed – possibly as signs of hypertension – and the eye lids are narrow – a sign of myopia. Furthermore, there is a thinning of the lateral third of the right eyebrow, which is known as Hertoghe’s sign, and indicated periorbital edema. Both signs are compatible with hypothyroidism. Bach might have been suffering from type-2 diabetes as the origin of his final illness, and the obituary reports two cataract surgeries by oculist John Taylor in March/April 1750, and, four months later, “apoplexy” followed by a high fever, of which Bach died. It may be speculated, however, that Bach’s entire illness was the result of his presumed obesity, possibly in combination with hypothyroidism.
Kommentar zum Artikel "Arthur Willis Goodspeed" von Otto Glasser, veröffentlicht in Science Vol. 98, Issue 2540, Seite 219 (doi.org/10.1126/science.98.2536.125).
Auf Grundlage der Computer-Aided-Design (CAD)-rekonstruierten ersten „Eisernen Hand“ des Götz von Berlichingen wird ein umgebautes, controllergesteuertes sensomotorisches Fingersystem auf seine Funktionalität beim Greifen von unterschiedlichen Gegenständen beschrieben und geprüft. Die elektronischen Finger, die den „Pinzettengriff“ nachahmen und automatisch bei dem zuvor eingestellten Anpressdruck abschalten, bewiesen eine bemerkenswerte Alltagstauglichkeit. Das vorgestellte Grundkonzept könnte eine Alternative bei der Entwicklung einfacher und kostengünstiger, aber dennoch gut einsatzfähiger bionischer Hände sein und zeigt einmal mehr, wie historische Ideen in die Gegenwart transferiert werden können.
