Privacy is commonly regarded as a regulatory requirement achieved via technical and organizational management practices. Those working in the field of informatics often play a role in privacy preservation as a result of their expertise in information technology, workflow analysis, implementation science, or related skills. Viewing privacy from the perspective of patients whose protected health information is at risk broadens the considerations to include the perceived duality of privacy; the existence of privacy within a context unique to each patient; the competing needs inherent within privacy management; the need for particular consideration when data are shared; and the need for patients to control health information in a global setting...

INTRODUCTION: Complex mechanisms underlie dry eye (DE) symptom provocation. In particular, corneal hypersensitivity may provoke symptoms in short tear break-up time (BUT) DE characterized by tear film instability. We hypothesized that improved tear film stability may alleviate corneal sensitivity in patients with short tear BUT DE. Therefore, we investigated the effect of topical diquafosol tetrasodium (DQS) on corneal sensitivity in unstable tear film DE. METHODS: This prospective, randomized study included 27 subjects (age: 39...

Adenoviral conjunctivitis comprises a large number of physician office visits in the United States and places a great financial burden on health care. It is estimated that the incidence of adenovirus infection to be as high as 20 million cases per year in the United States. There are multiple adenovirus serotypes, each associated with different types and severity of infection. Ocular manifestations of adenovirus include epidemic keratoconjunctivitis, pharyngoconjunctival fever, and nonspecific conjunctivitis...

We present a case of an unexpected focally increased radiotracer uptake in an artificial eye in an FDG-PET/CT scan that was performed on a woman with a history of choroidal melanoma. It is crucial to know the type of prosthesis used and the timing of replacement for a correct interpretation of the findings. Recently, an FDG PET/CT was proposed to monitor the vascularity of the prosthesis instead of gadolinium MRI or of Tc bone scintigraphy.

Background: To report two cases of rhegmatogenous retinal detachment (RRD) associated with asteroid hyalosis (AH). Case Presentation: Two patients presented with RRD originating from a flap tear. Case 1 involved a 62-year-old male who was found to have bullous RRD in his left eye originating from a flap tear. During vitreous surgery, a thick vitreous cortex was found to have strongly adhered to the entire retinal surface, from the center to the periphery. A bimanual method was then used in conjunction with the vitrectomy to create an artificial posterior vitreous detachment...

The term, autosomal recessive congenital ichthyosis (ARCI), describes a group of rare genetic skin diseases of cornification involving hyperkeratotic scaling at birth. The defective skin barrier function may lead to dehydration, body temperature instability, and high susceptibility to infections. In most cases of ARCI, neonates are born with a collodion membrane covering the body, often presenting with ectropion and eclabium. We report a premature female neonate presenting with hyperkeratotic scaling at birth without a collodion membrane...

The high incidence of Diabetes Mellitus in low-income regions has promoted the development of low-cost alternatives to replace blood-based procedures. In this work, we present a bienzymatic paper-based sensor suitable for the naked-eye detection of glucose in saliva samples. The sensor was obtained by a stamping procedure and modified with chitosan to improve the colorimetric readout. The bienzymatic reaction of GOx-HRP coupled with 2,4,6-tribromo-3-hydroxy benzoic acid was applied for the detection of glucose within a range from 0 to 180 mgdL-1 in buffer and artificial saliva solutions...

- Motion sickness is not a disorder, but a normal response to a non-normal situation in which movement plays a central role, such as car travel, sailing, flying, or virtual reality.- Almost anyone can suffer from motion sickness, as long as at least one of the organs of balance functions. If neither of the organs of balance functions the individual will not suffer from carsickness, seasickness, airsickness, nor from cybersickness. - 'Cybersickness' is a form of motion sickness that is stimulated by artificial moving images such as in videogames...

Digital hemispherical photography (DHP) has been widely used to estimate leaf area index (LAI) in forestry. Despite the advancement in the processing of hemispherical images with dedicated tools, several steps are still manual and thus easily affected by user's experience and sensibility. The purpose of this study was to quantify the impact of user's subjectivity on DHP LAI estimates for broad-leaved woody canopies using the software Can-Eye. Following the ISO 5725 protocol, we quantified the repeatability and reproducibility of the method, thus defining its precision for a wide range of broad-leaved canopies markedly differing for their structure...

Fast Green (FCF) dye is commonly used in both cytology and histology applications. Previous studies have found that it can cause mutagenic and tumorigenic effects in experimental human and animal populations. It can also be a source of skin, eye, respiratory, and digestive irritation. The purpose of this study was to examine the use of thin film membranes to degrade FCF. A thin film membrane of chitosan (CS) was fabricated and subsequently filled with zinc oxide nanoparticles (ZnO) or ZnO/CuO-heterostructured nanocomposites...
