One hundred and fifteen patients, between 6 months and 12 years of age, had bronchoscopy on suspicion of foreign body aspiration. The histories of these patients were studied to examine the diagnostic value of signs, symptoms and examinations, and to determine the time that passed between aspiration and removal of the foreign body. The sensitivity of the symptoms choking and coughing was fairly high (81 and 78%), but the specificity was poor. The sensitivity of a chest radiograph was 82%, the specificity 44%. The sensitivity of radiographs on inspiration and expiration was 80%, the specificity 55%. The patients had been referred with the initial diagnosis foreign body aspiration (80), pneumonia (34), or subglottic laryngitis (1). In 85 patients a foreign body was identified and extracted. The other 30 patients had respiratory tract infections. The initial diagnosis of foreign body aspiration was correct in 61 out of 85 patients. In these cases, the period between aspiration and extraction of the foreign body was a mean 6 days, compared with 55 days, if the initial diagnosis was pneumonia or sub-glottic laryngitis. We conclude that the diagnosis of foreign body aspiration is too often missed, and that, apart from bronchoscopy, diagnostic tools are of little value.
The infantile subglottic hemangioma can be treated in various ways. The results of the treatment used in the Sophia Children's Hospital, intralesional steroids and intubation (IS + I), are discussed and compared with the results of other current treatment methods: CO2 laser vaporization, submucous resection and intubation alone. A total of 18 infants were treated for subglottic hemangioma in our hospital: ten with IS + I alone, five were first treated with systemic therapy and later with IS + I alone and three with various therapies. IS + I was effective in 14 of the 15 patients, one patient was lost from follow up. The remaining three infants were treated with (combinations of) various therapies, because IS + I failed or was not tried. Two patients were finally cured, one still has a tracheotomy. Of other current therapies, CO2 laser vaporization is reported to be effective. In all 30% of the infants treated in Boston Children's Hospital with CO2 laser needed a tracheotomy. Moreover subglottic stenosis is a serious complication. Submucous resection is often successful. It may be complicated by subglottic stenosis and in some cases, depending on the localization of the hemangioma, it may be contraindicated. Intubation alone is less effective than intubation combined with intralesional steroids. Management of subglottic hemangioma in Sophia Children's Hospital is primarily intralesional steroids and intubation and secondarily submucous resection or tracheotomy. CO2 laser vaporization is seldom applied because of the risk of subglottic stenosis.
Laser myringotomy is a safe but less-effective procedure than insertion of a ventilation tube in the treatment of chronic OME. The prognostic model enables the otolaryngologist to choose the surgical treatment for the child that benefits most: laser myringotomy or ventilation tube.
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.
