A typical moles and melanoma will have a different optical profile based on physiological parameters compared to benign nevus. The first measured is to determine the hardware variability. From this optical data, a "correction" curve will be developed a...

Assessment of Cholangio-pancreatoscopy for the Diagnosis and the Treatment of Biliary and Pancreatic Diseases

The biliary and pancreatic tumors are rare but the prognosis is pejorative. It was difficult to have histology of these tumors as the samples taken during ERCP were performed under " blind " radiology control. So the diagnostic accuracy was insufficient. The arrival of A new optic fiber endoscope used by only one operator had improved the diagnostic of bilio-pancreatic diseases. However this technology with optic fiber quickly had proved outdated for several reasons: poor mano...

Vitreo-papillary Traction as an Entity Identified by Optical Coherence Tomography (OCT).

Optical Coherence Tomography (OCT) is a relatively new imaging technique in ophthalmology. This clear and documented imaging identified new diseases/ observations that were not previously known.

Autofluorescent Flavoprotein Imaging of Intraepidermal Nerve Fibers: a Pilot Study

Small fiber neuropathy (SFN) is a common disorder, which has a profound negative impact on quality of life because of severe neuropathic pain. To reliably establish a diagnosis of SFN is challenging, since neurological examination and nerve conduction studies are often normal. Autofluorescent flavoprotein imaging (AFI) is an optical method through which neuronal activity in the termination area of small nerve fibers in the spinal cord can be quantified. Since the epidermis also...

Optical Stimulation Rhizotomy Study

The purpose of this study is to determine the safe and effective levels of optical stimulation in peripheral nerves of humans otherwise undergoing nerve lesioning in surgery.

Optical Detection of Intravenous Infiltration

The purpose of this study is to investigate the safety and efficacy of an optical device designed and developed for monitoring the intravenous infusion site for infiltration. The hypothesis is that the changes in optical signals measured near the infusion site using the optical device can be used to monitor intravenous infusion for infiltration.

The Effects of Fiber on Appetite and Digestion Hormones

In this research study, investigators are interested in how certain dietary fibers in the diet affect certain hormones released from your intestine after eating and how these influence your appetite. The study hypothesis is that certain fibers will slow digestion and absorption of nutrients thereby optimizing fullness,reducing food intake and limiting insulin response in pre- and post-menopausal women.

Treatment of Infected Dialysis Catheters With Fiber Optic Ultraviolet Light

This study is a first-in-man clinical trial using fiber optically delivered ultraviolet light for reducing viable bacteria within indwelling tunneled dialysis catheters.

Optical Tomographic Scanner for Skin Lesions

Optical coherence tomography is technology widely used in medicine. In this study, we will use an optical tomographic scanner to scan skin tissue image.

The Massachusetts General Hospital Optical Coherence Tomography Registry

Information will be collected prospectively in about 3,000 patients having Optical Coherence Tomography during cardiac catheterization. Subjects will be initially enrolled at sites outside of the United States, where Optical Coherence Tomography is approved by regulatory agencies. Subjects will be followed for up to 5 years.

Optical Coherence Tomography and Optic Neuritis (OCTON)

Optic neuritis (ON) can remain isolated or reveal a widespread and chronic disease of the central nervous system (CNS), a multiple sclerosis (MS) or, more rarely, a Devic's neuromyelitis optica (NMO) or a systemic disease. The optical coherence tomography (OCT) is a retinal imaging technique to measure the thickness of the retina and its different layers with an accuracy of 4-6 µM. Costello et al have shown that approximately 75% of 54 MS patients have developed within 3 ...

Real Time Optical Coherence Tomography (OCT) of Human Tissue

This is a single-arm, prospective, study of an optical imaging device on approximately twenty (20) subjects undergoing lumpectomies at one study site. In vivo and ex vivo imaging will be performed on study subjects with results being compared to final pathology.

Novel Diagnostics With Optical Coherence Tomography: Retinal Imaging

The purpose of this research is to evaluate optical coherence tomography (OCT) and FDA approved device used to image diseases of the eye. The ultra-high resolution OCT is a non-significant risk device used in this study. Optical Coherence Tomography may be useful for early diagnosis and monitoring of different types of eye diseases.

Optical Coherence Tomography Measurements in Eyes With Band Atrophy

The study is designed to evaluate the ability of optical coherence tomography and VCC scanning laser polarimetry to measure and identify the pattern of band atrophy of the optic nerve in patients with long standing chiasmal lesions. The hypothesis is that these new technologies are able to identify such pattern. The idea is that by using eyes with band atrophy one is able to investigate the ability of the new technologies in measuring the retinal nerve fiber layer particularly ...

Optical Clearing of the Skin in Conjunction With Laser Treatments

The research hypothesis is that topical application of a mixture of pre-polymers of polypropylene glycol and polyethylene glycol (an optical clearing agent) will reduce skin light scattering, increasing the amount of light reaching the target for diagnostic as well as therapeutic purposes.

The Effect of Different Types of Dietary Fiber on Satiation

It has been suggested that dietary fibers can affect food intake and satiation. Satiation, or meal termination, can be induced by sensory properties and energy density of fiber-rich food products, but also by the chemical/physical/rheological behavior of the fibers in the stomach and/or intestine. It is not clear which properties are the key regulators of satiation by fiber sources. There are many types of dietary fiber, which have diverse sensory and chemical properties, thus ...

Effect of Potato Fiber on Appetite and Fecal Fat Excretion

Results have indicated that some dietary fibers increase fecal fat excretion and particularly viscous fibers suppress appetite sensation and reduce energy intake. Both these effects may contribute to body weight management. Aim: The aim of the study is to investigate the potential of 3-weeks daily intake of potato pulp (FiberBind), rhamnogalacturonan I isolated potato fiber (RG-I) vs. a low-fiber control (placebo) on satiety and fecal fat excretion in healthy adults. Furthermo...
