Using a hand-held spectral domain optical coherence tomography (SD-OCT) imaging device, researchers have obtained high-resolution retinal scans of premature infants with progressive retinopathy of prematurity (ROP), according to a report in this month's Archives of Ophthalmology. Researchers reported the new hand-held devices eliminated many of the technical challenges involved in imaging the retina of infants and can enable shallow detachments and presumed retinoschisis to be diagnosed earlier and more accurately, significantly altering how physicians may classify and treat babies with this disease. "The SD-OCT demonstrated presumed retinoschisis extending from the temporal ridge in three premature infants.
A team of neurosurgeons at Heidelberg University Hospital and psychiatrists at the Central Institute of Mental Health, Mannheim have for the first time successfully treated a patient suffering from severe depression by stimulating the habenula, a tiny nerve structure in the brain. The 64-year-old woman, who had suffered from depression since age 18, could not be helped by medication or electroconvulsive therapy. Since the procedure she is, for the first time in years, free of symptoms. Scientific studies have shown that the habenula is hyperactive in depression, the idea was to downregulate this structure by deep brain stimulation. The surgical procedure is based on a hypothesis of how the habenula is involved in depression that was first formulated by Dr.
Thanks to medical imaging techniques such as X-ray CT, ultrasound imaging and MRI, doctors have long been able to see to varying degrees what's going on inside a patient's body, and now a Texas A&M University mathematician is trying to find new and better ways to do so. The professor, Peter Kuchment, a leading researcher in mathematical techniques for medical imaging, says the research may enhance the process for detecting cancer and many other diseases. When talking about medical imaging, most people know that physics and computer sciences are involved, but few may be aware that mathematics is indispensable. Indeed, many imaging methods are based on mathematical analysis.
An article Online First and in the February edition of The Lancet Neurology reports that brain scans using positron emission tomography (PET) can identify with high accuracy which form of Parkinsonism a patient has. Such early diagnosis is essential to make sure that patients receive the correct treatment and do not receive ineffective treatments due to misdiagnosis. The article is the work of Dr David Eidelberg, Center for Neurosciences, The Feinstein Institute for Medical Research, Manhasset, NY, USA, and colleagues. Parkinson's disease arising spontaneously can present with symptoms comparable to those of multiple system atrophy or progressive supranuclear palsy.
Aneeve Nanotechnologies LLC has been selected to work in the UCLA on-campus Technology Incubator Program at the California NanoSystems Institute. The startup company will conduct early-stage research for the development of a novel hormone sensor/meter for biomedical applications in the areas of infertility and menopause. Aneeve has licensed related carbon nanotube technology from UCLA developed by Kang Wang, a UCLA professor of electrical engineering. The technology increases hormonal detection sensitivity significantly, allowing detection beyond traditional sensors. The company is using this technology to develop biomedical applications that are low in power consumption and small in size and that involve ultra-sensitive nanoelectronic technologies.
Odysseus has developed systems to construct 3D images of individual patients' livers, with their tumours or other pathologies, from MRI or CT-scans. The reconstructions can be transmitted to external experts in any location, for consultation in real time just before surgery. Collaborative decisions can be made and optimal therapy planned with the best possible diagnostic support, before real surgery is attempted. Simulation of laparoscopic and robotic surgery, with tissue resistance, can be used either to practise the exact surgery proposed for an individual patient, or also for training several surgeons simultaneously. Medical imaging of organs and tissues has contributed greatly to diagnosis and therapy planning, especially in the treatment of cancers, which are the major cause of deaths worldwide.
