AbstractBackgroundRecurrent respiratory papillomatosis is a rare but morbid disease caused by human papillomavirus (HPV) types 6 and 11. Infection is preventable through HPV vaccination. Following an extensive quadrivalent HPV vaccination program (females 12–26 years in 2007–2009) in Australia, we established a method to monitor incidence and demographics of juvenile-onset recurrent respiratory papillomatosis (JORRP) cases.MethodsThe Australian Paediatric Surveillance Unit undertakes surveillance of rare pediatric diseases by contacting practitioners monthly. We enrolled pediatric otorhinolaryngologists and offered HPV typing. We report findings for 5 years to end 2016.ResultsThe average annual incidence rate was 0.07 per 100000. The largest number of cases was reported in the first year, with decreasing annual frequency thereafter. Rates declined from 0.16 per 100000 in 2012 to 0.02 per 100000 in 2016 (P = .034). Among the 15 incident cases (60% male), no mothers were vaccinated prepregnancy, 20% had maternal history of genital warts, and 60% were first born; 13/15 were born vaginally. Genotyped cases were HPV-6 (n = 4) or HPV-11 (n = 3).ConclusionTo our knowledge, this is the first report internationally documenting decline in JORRP incidence in children following a quadrivalent HPV vaccination program.
Tracheostomy indication and patient diagnosis are significant variables that predict early decannulation in pediatric patients in whom tracheostomy is required. Other variables were not shown to be significant independent predictors.
We undertook a retrospective study to examine our experience with acute mastoiditis over a 12-year period. Fifty-eight cases were identified in children aged 3 months to 15 years. Acute mastoiditis was the first evidence of otitis media in 54% of our patients. Pain and fever lasting for more than a median period of 4 days were most likely to be the harbingers of incipient acute mastoiditis. Streptococcus pneumoniae was the most common organism recovered from the cultures. All children were treated with intravenous antibiotics; 41 children were managed with an adjunctive drainage procedure. No statistically significant differences were observed between the cure rates and failure rates for children treated surgically with myringotomies with or without tubes and children managed more aggressively with mastoidectomies. One infant had bacterial meningitis. Cholesteatoma was diagnosed in two children. We conclude from our study that acute mastoiditis occurs mainly in young children and may be the first evidence of ear disease. Pain and fever that persist despite appropriate treatment for acute otitis media are the two most important symptoms. Intravenous antibiotics combined with myringotomy with or without tube insertion are as appropriate as intravenous antibiotics with mastoidectomy for initial management of acute mastoiditis in the absence of a subperiosteal abscess or central nervous system extension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
