BACKGROUND: People with Parkinson's disease (PD) often have visual-perceptual disorders. The goal of this study was to learn if they can develop a three dimensional (3D) percept that depends on the kinetic depth effect; that is, the viewer's ability to spatially integrate over time images that are moving along many trajectories. METHODS: Sixteen patients with PD and 12 healthy matched controls were presented with stimuli that were comprised of a circular region of randomly placed dots that moved as orthographic projections of a sphere...

Wind erosion not only affects agricultural productivity but also soil, air, and water quality. Dust and specifically particulate matter ≤10 μm (PM-10) has adverse effects on respiratory health and also reduces visibility along roadways, resulting in auto accidents. The Wind Erosion Prediction System (WEPS) was developed by the USDA-Agricultural Research Service to simulate wind erosion and provide for conservation planning on cultivated agricultural lands. A companion product, known as the Single-Event Wind Erosion Evaluation Program (SWEEP), has also been developed which consists of the stand-alone WEPS erosion submodel combined with a graphical interface to simulate soil loss from single (i...

Fatal craniovertebral junction (CVJ) injuries were the most common cause of death in high-speed motor sports prior to 2001. Following the death of a mutual friend and race car driver, Patrick Jacquemart (1946-1981), biomechanical engineer Dr. Robert Hubbard, along with race car driver and brother-in-law Jim Downing, developed the concept for the Head and Neck Support (HANS) device to prevent flexion-distraction injuries during high-velocity impact. Biomechanical testing showed that neck shear and loading forces experienced during collisions were 3 times the required amount for a catastrophic injury...

INTRODUCTION: According to the latest version of the Abbreviated Injury Scale (AIS), all Thoraco-Lumbar Compression Fractures (TLCF) with >20% loss of height, were branded code 3 injuries, reflecting a threat for life or permanent disability. However, clinical observation suggests that that TLCF with <40% loss of height and without neurological deficits, have been noted to have a better clinical prognosis, prompting the need to segregate these injuries differently, revise the classification, and review outcomes...

RATIONALE: Fragments of glass from cars are often found at crime scenes and can be crucial evidence for solving the crime. The glass fragments are important as trace evidence at crime scenes related to car accidents and burgled homes. By identifying the origin of glass fragments, it is possible to infer the identity of a suspect. Our results represent a promising approach to a thorough forensic investigation of car glass. METHODS: Thirty-five samples from the side windows of cars produced and used in South Korea were collected from the official agencies of five car manufacturers and from two glassmakers...

Differential mobility spectrometry (DMS) is currently being used for environmental monitoring of space craft atmospheres and has been proposed for the rapid assessment of patients at accident and emergency receptions. Three studies investigated hitherto undescribed complexity in the DMS spectra of methanol, ethanol, propan-1-ol and butan-1-ol product ions formed from a (63)Ni ionisation source. 54 000 DMS spectra obtained over a concentration range of 0.01 mg m(-3)(g) to 1.80 g m(-3)(g) revealed the phenomenon of auto-modification of the product ions...

This paper will explore the fire and explosion characteristics of cornstarch powder as well as strategies for protecting the safety of people who are involved a dust fire or dust explosion. We discuss the 5 elements of dust explosions and conduct tests to analyze the fire and explosion characteristics of differently colored powders (yellow, golden yellow, pink, purple, orange and green). The results show that, while all of the tested powders were difficult to ignite, low moisture content was associated with significantly greater risks of ignition and flame spread...

BACKGROUND: The cost of medical care is an area of major emphasis in the current healthcare environment. Medical providers have a significant role in reducing costs. One way to achieve this goal is to eliminate practices that add little value to patient care. The pelvic x-ray (PXR) obtained during the initial evaluation of blunt trauma may be an example. The objective of this study was to explore the utility of the pelvic x-ray in the initial evaluation of blunt trauma patients. METHODS: Blunt trauma patients with pelvic fractures of any type admitted to our urban trauma center from January 2012 to December 2013 were reviewed...

INTRODUCTION: Medical errors in hospitals kill more people every year than AIDS, breast cancer and auto accidents combined. Widespread consensus exists that health care organizations can reduce patient injuries by improving the environment for safety from implementing different alternatives from technical and managerial improvements to considering medical record data. Considering the preventability of medical errors, the Agency for Healthcare Quality and Research (AHRQ) developed patient safety indicators (PSIs)...

OBJECTIVE: The current study examines the variation in alcohol use among nightclub patrons under three transportation conditions: those who departed from a club using modes of transportation other than cars or motorcycles (e.g., pedestrians, bicyclists, subway riders); those who were passengers of drivers (auto/taxi passenger patrons); and those who drove from the club (driving patrons). We seek to determine whether patrons' choice for how to leave the club contributes to their risk, as assessed by blood alcohol concentrations (BAC), after controlling for other factors that may contribute to their BAC including demographic characteristics and social drinking group influences...

A bystander calls 911 after witnessing an auto accident in rural Minnesota in which a passenger has been seriously injured. The dispatcher provides the caller with instructions on how to care for the person until the ambulance arrives. When emergency medical services personnel get to the scene, they find that the patient meets the criteria for trauma and activate a "trauma code" at the local hospital. Upon receiving that radio notification, the hospital calls in additional staff and also calls for a helicopter to transfer the patient to a tertiary care trauma center...

Mathematical models of the cardiovascular system and of cerebral autoregulation (CAR) have been employed for several years in order to describe the time course of pressures and flows changes subsequent to postural changes. The assessment of the degree of efficiency of cerebral auto regulation has indeed importance in the prognosis of such conditions as cerebro-vascular accidents or Alzheimer. In the quest for a simple but realistic mathematical description of cardiovascular control, which may be fitted onto non-invasive experimental observations after postural changes, the present work proposes a first version of an empirical Stochastic Delay Differential Equations (SDDEs) model...

BACKGROUND: Needle-stick injuries accounts for a great proportion of all medical accidents in developing and undeveloped countries. The main cause of needle-stick accident injuries is the medical personnel's ``recovering'' the needle action after injection. OBJECTIVE: This study applies an electronic technique to the needling instrument for the purpose of automatically detaching the needle. The proposed method can effectively avoid needle-stick accident injury when ``recovering'' the needle...

BACKGROUND: Tumors involving the root of the mesentery are generally regarded as "unresectable" with conventional surgical techniques. Resection with conventional surgery may end in life-threatening complications in these patients. Ex-vivo resection and auto-transplantation avoids excessive bleeding and prevents ischemic related damage to the small intestine and other organs. OBJECTIVE: To share our experience of ex-vivo resection of the tumors with involvement of small bowel mesentery followed by small bowel auto-transplantation...

BACKGROUND: Genital losses from ritual attacks are often reported in the media and often discussed in the social media but are hardly reported in medical literature. Male genital mutilation (MGM) refers to permanent modification of the external genitalia that involves ablation of genital tissues.When found, it is usually as a consequence of poor circumcision skills, auto mutilation/castration or genital injuries caused by attacks or accidents. Male circumcision on its own is widely regarded as a rather safe and acceptable practice which is known to have some health benefits and in keeping with several religious customs as rite of passage...
