Background: Current knowledge of clinical features of imported childhood malaria is largely limited to small, retrospective, and/or single-center case series. This prospective, population-based study describes the epidemiology and clinical features of imported childhood malaria in children <16 years in the United Kingdom and Republic of Ireland.

Methods: Active prospective national surveillance with clinical data collection was performed between January 1, 2006 and January 31, 2007 through the British Pediatric Surveillance Unit and capture-recapture analysis using cases reported independently to respective national surveillance centers.

Imported malaria is a preventable disease, yet it is responsible for several thousand cases and a substantial number of deaths every year. There has been a pronounced rise in the incidence of imported malaria in most developed countries over the past three decades and, more concerning, Plasmodium falciparum, which is responsible for almost all cases of severe malaria, is now the most prevalent species. Children account for around 15-20% of all imported malaria cases and must be considered separately from adults because they have different risk factors for developing malaria and a higher risk of developing severe disease since they are more likely to be non-immune to malaria.

Objective: To describe the epidemiology of imported malaria in children in the UK.

Methods: Surveillance data on children with imported malaria, collected through an enhanced surveillance network set up by the Malaria Reference Laboratory (London, UK), diagnosed between January 1999 and December 2003 were analysed.

Results: Over the 5-year study period, 9238 cases were reported to the Malaria Reference Laboratory, and children accounted for 1456 (14.

The middle-ear pressure gain, defined as the ear canal sound pressure to cochlear vestibule pressure gain, GME, and the ear canal sound pressure to stapes footplate velocity transfer function, SVTF, simultaneously measured in 12 fresh human temporal bones for the 0.05 to 10 kHz frequency range are reported. The mean GME magnitude reached 23.
