Detection of coins ingested by children using a handheld metal detector: a systematic review.

To determine if the use of a handheld metal detector (HHMD) can safely reduce the number of radiographs requested in cases of coins ingested by children, a search was performed to identify prospective studies of the ability of an HHMD to identify the presence or absence of ingested coin in children (17 years or younger). Outcome measures were presence or absence of coin on metal detector screen...

The first purpose of the paper is to show the connection between this problem and a problem in lattice geometry. Using this approach, we are able to establish an upper bound on the ...
