AIM Ultrasound may be a cheap alternative to scintigraphic determination of splenic function. We directly compared nanocolloid scintigraphy (NS), scintigraphy with heat-altered erythrocytes (ES), and colour-coded Doppler sonography (DS) in patients with chronic inflammatory bowel disease (CIBD). PATIENTS, METHODS 35 patients were included into the study.(More)
The National Highway Traffic Safety Administration has concluded that there is a relationship between roof intrusion and the risk of injury to belted occupants in rollovers events. Previous testing on many different production vehicle types indicates that damage consistent with field rollover accidents can be achieved through inverted drop testing from(More)
Roof crush occurs and potentially contributes to serious or fatal occupant injury in 26% of rollovers. It is likely that glazing retention is related to the degree of roof crush experienced in rollover accidents. Occupant ejection (including partial ejection) is the leading cause of death and injury in rollover accidents. In fatal passenger car accidents(More)
Occupant kinematics and the potential for injury in vehicular rollover crashes are dramatically affected by various restraint system characteristics. This study reviews previous research that utilized various methodologies and test fixtures to evaluate restrained occupant motions, primarily in the vertical direction, during both inverted and quasi-static(More)
Inverted drop testing of vehicles is a methodology that has long been used by the automotive industry and researchers to test roof integrity and is currently being considered by the National Highway Traffic Safety Administration as a roof strength test. In 1990 a study was reported which involved 8 dolly rollover tests and 5 inverted drop tests. These(More)
Traumatic brain injuries (TBI) are common in sports accidents. Helmets are generally known to provide protection to the head. However, the effectiveness of helmets in mitigating a TBI may be compromised due to the impact location and impact speed. Although it is known that the helmet decreases the linear head accelerations and the resulting head injury(More)
The multi-planar and multiple impact long duration accident sequence of a real world rollover results in multidirectional vehicle acceleration pulses and multiplanar occupant motions not typically seen in a planar crash sequence. Various researchers have documented that, while contemporary production emergency locking seatbelt retractors (ELRs) have been(More)
Seat belt system restrains and protects occupants in motor vehicle crashes and any slack in seat belt system induces additional loading on occupant. Signs of belt loading are more obvious in high-speed frontal collisions with heavy occupants. However subtle changes may occur at low speeds or with low forces from occupants during rollovers. In certain cases,(More)
With regard to aetiology, location and therapy, fractures of the facial skeleton in childhood occupy a special position due to the anatomico-morphologic pecularities of the infantile skull. To verify this statement, the author analysed the medical records of 58 patients with fractures of the facial skeleton, having an age range from 1 to 14 years. The(More)
The National Highway Traffic Safety Administration (NHTSA) has concluded that there is a relationship between roof intrusion and the risk of injury to belted occupants in rollovers events [1]. Previous testing on many different production vehicle types indicates that damage consistent with field rollover accidents can be achieved through inverted drop(More)
