Cervicofacial emphysema and pneumomediastinum following pediatric adenotonsillectomy: a rare complication.

Cervicofacial emphysema and pneumomediastinum are rarely observed sequelae of surgical intervention in the upper aerodigestive tract. It is a potentially life-threatening condition but the majority of cases are self-limiting and benign. Symptoms include chest pain, neck pain, dyspnea and odynophagia. A case occurring after adenotonsillar surgery in a 7-year-old child is presented. This report highlights this unusual complication and its potential to delay the postoperative recovery following adenotonsillectomy.

Ototoxic eardrops and tympanic membrane perforations: time for a change?

Until recently the only available antibiotic eardrops for treatment of the discharging middle ear and mastoid cavity have been potentially ototoxic. With the advent of non-ototoxic fluoroquinolone eardrops, consensus panels in the USA, Canada and the UK have advocated the preferential use of these agents in the open middle ear. However, in Australia, no fluoroquinolone topical agent is approved for use with tympanic membrane perforations, and when used as an 'off label' eardrop, none is on the Pharmaceutical Benefits Scheme. This creates an ethical dilemma, particularly with best practice management of chronic suppurative otitis media in indigenous children. Despite concerns regarding resistance issues with ototopical use of systemic antibiotics, bacterial resistance has not been documented in major studies. For equity and ethical reasons, Australian regulatory authorities should consider approving a sterile non-ototoxic eardrop for use in the open middle ear.

Benefits of swimming pools in two remote Aboriginal communities in Western Australia: intervention study.

OBJECTIVE: To determine the health impact of swimming pools built with the aim of improving quality of life and reducing high rates of pyoderma and otitis media. DESIGN: Intervention study assessing prevalence of ear disease and skin infections before and at six monthly intervals after opening of swimming pools. SETTING: Two remote Aboriginal communities in Western Australia. PARTICIPANTS: 84 boys and 78 girls aged < 17 years. MAIN OUTCOME MEASURES: Changes in prevalence and severity of pyoderma and perforation of tympanic membranes with or without otorrhoea over 18 months after opening of pools. RESULTS: In community A, 61 children were seen before the pool was opened, and 41, 46, and 33 children were seen at the second, third, and fourth surveys. Equivalent figures for community B were 60, 35, 39, and 45. Prevalence of pyoderma declined significantly from 62% to 18% in community A and from 70% to 20% in community B during the 18 months after the pools opened. Over the same period, prevalence of severe pyoderma fell from 30% to 15% in community A and from 48% to 0% in community B. Prevalence of perforations of the tympanic membrane fell from 32% in both communities to 13% in community A and 18% in community B. School attendance improved in community A. CONCLUSION: Swimming pools in remote communities were associated with reduction in prevalence of pyoderma and tympanic membrane perforations, which could result in long term benefits through reduction in chronic disease burden and improved educational and social outcomes.

Otolaryngological manifestations of ligneous conjunctivitis.

Ligneous conjunctivitis is a rare condition that can involve the mucous membranes of the upper and lower airways and temporal bone extensively. This can lead to life threatening airway obstruction. Involvement of the middle ear and mastoid may cause significant conductive hearing loss. This is the first reported case with temporal bone sections of ligneous conjunctivitis, and awareness of the associated obstructive hydrocephalus may prevent death in this condition. Evidence suggests that plasminogen deficiency may be a causative factor in ligneous conjunctivitis, and this finding may offer new prospects for management.
