MONDAY, Jan. 19 (HealthDay News) -- Antibiotic-resistant infections around the head and neck are on the rise among American children, a new report indicates.

The finding suggests that tougher strains of the bacteria Staphylococcus aureus -- referred to as MRSA because of their resistance to the antibiotic methicillin -- are moving beyond the traditional confines of hospitals and into the community at large.

"We certainly found that the emergence of resistant staph head and neck infections in pediatric settings is on the rise," said study co-author Dr. Steven E. Sobol, director of the department of pediatric otolaryngology at the Emory University School of Medicine in Atlanta.

Sobol and his colleagues reported the findings in the January issue of the Archives of Otolaryngology Head & Neck Surgery.

The building threat to children compounds a trend toward more community-based MRSA infections previously observed among prison, nursing home, and chronically ill patient populations, the researchers noted.

In the latest study, the authors reviewed data concerning pediatric infections that had been collected between 2001 and 2006 in a national database that amasses anti-microbial drug resistance test results from labs working for more than 300 hospitals across the country.

The research team found that of the more than 21,000 infections that had occurred among children during the study period, almost 22 percent were resistant to the antibiotic methicillin. Overall, MRSA head and neck infection rates had more than doubled, from about 12 percent to just over 28 percent.

About one-third of MRSA infections affected the ears, while about 28 percent impacted the nasal and sinus regions. Head and neck MRSA infections accounted for about 14 percent of the total.

Sobol stressed, however, that the apparent rising MRSA risk to children is not yet cause for alarm.
