Magnet ingestions by children have received increasing attention over the past 10 years.
With the growing availability of new and stronger neodymium-iron-boron magnets being sold as "toys," there has been an increase of cases of ingestion, resulting in serious injury and, in some cases, death.
In a new study scheduled for publication in The Journal of Pediatrics, researchers studied the trends of magnetic ingestions at The Hospital for Sick Children (SickKids), Canada's largest children's hospital.
Matt Strickland, MD, and colleagues reviewed all cases of foreign body ingestion seen in the emergency department from April 1, 2002 through December 31, 2012. Inclusion criteria included being less than 18 years of age, with suspected or confirmed magnetic ingestion.
According to Dr. Strickland, "We chose to limit our scope to the alimentary tract because the majority of serious harm from magnets arises from perforations and fistulae of the stomach, small bowel, and colon." To reflect the introduction of small, spherical magnet sets in 2009, the study was divided into two time periods, visits during 2002-2009 and those during 2010-2012.
Of 2,722 patient visits for foreign body ingestions, 94 children met the inclusion criteria. Of those, 30 children had confirmed ingestion of multiple magnets. Overall magnet ingestions tripled from 2002-2009 to 2010-2012; the incidence of injuries involving multiple magnets increased almost 10-fold between the two time periods.
Six cases required surgery for sepsis or potential for imminent bowel perforation, all of which occurred in 2010-2012. The average size of the magnets also decreased approximately 70% between 2002-2009 and 2010-2012.
This study shows a significant increase in the rate of multiple magnet-related injuries between 2002 and 2012. "More concerning, however," notes Dr. Strickland, "is the increased number of high-risk injuries featuring multiple, smaller magnets."
Despite new magnet-specific toy standards, labeling requirements, product recalls, and safety advisories issued in the past 10 years, continuing efforts should focus on educating parents and children on the dangers inherent in magnetic "toys."

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
