Obstruction in the Pedriatic Airway: diagnostic and therapeutic aspects

Pediatric Laryngology in a referral hospital for children such as the Sophia Children's Hospital is to a large extent concerned with patients suffering from airway obstruction, most of whom, owing to the nature of the disorder, are treated in an Intensive Care Unit (lCU). The otorhinolaryngologist, in close cooperation with ICU-pediatricians, is confronted with a great variety of airway pathology: intubation or tracheotomy related problems, post-intubation injury, cicatricial laryngeal stenosis, congenital laryngeal stenosis, subglottic hemangioma, choanal atresia, pharyngeal obstruction, epiglottitis, subglottic laryngitis, tracheomalacia, etc. Laryngobronchoscopy (LBS) is the most important tool in the diagnosis of such disorders in children

Two tendencies in totalitarian Economics

textabstractAbstract In the Sophia Children's Hospital we perform fiberoptic laryngoscopy in neonates under general anesthesia without the use of muscle relaxants in the diagnostics of functional laryngeal disorders. The necessary diagnostic and anesthetic equipment is described. Special attention is paid to the way in which the fiberscope is introduced into the breathing circuit and into the child's airway. Several advantages over other methods are discussed. The procedure has proved to be easy, safe and informative

Management of infantile subglottic hemangioma: Laser vaporization, submucous resection, intubation, or intralesional steroids?

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

Differences in nasal cellular infiltrates between allergic children and age-matched controls

Little is known about the cellular infiltrates in the nasal mucosa of children. This study was set up to compare the nasal cellular infiltrates in biopsy specimens from allergic children and controls. Atopic children were distinguished from controls on the basis of symptoms of allergic rhinitis and/or asthma, total serum immunoglobulin (Ig)E, family history and specific serum IgE to food and aeroallergens. Fifteen allergic patients (median age 4.3 yrs) and 15 age-matched nonallergic control subjects were evaluated. The number of cells positive for CD1a, CD4, CD8, CD19, CD68, chymase, tryptase, IgE and major basic protein was determined in the mucosa of the inferior turbinate. A significantly higher number of IgE-positive cells and mast cells was found in the epithelia of the allergic group. In the lamina propria, higher numbers of IgE-positive cells and eosinophils were found. Langerhans' cells positive for IgE were only seen in allergic children with specific serum IgE against aeroallergens. These children also had a higher number of IgE-positive mast cells compared to controls and atopic children without specific serum IgE. These results show that the nasal cellular infiltrates of allergic children differ from nonallergic control subjects. Prior to the detection of specific serum immunoglobulin E, cellular changes can be found in the nasal mucosa of atopic children

Ectopic cartilage in subglottic stenosis: Hamartoma or reaction to trauma?

In an experimental study in growing rabbits an endolaryngeal injury to the subglottis resulted in the development of a stenosis due to the formation of scar tissue containing ectopic cartilage. For comparison, biopsies taken from the subglottic stenosis in 8 children were studied histologically. In 6 cases ectopic cartilage was observed; all patients had a history of endotracheal intubation. In 3 children the diagnosis hamartoma was made. In the remaining 3 cases the formation of ectopic cartilage might have been a direct reaction to the endolaryngeal intubation. The observations suggest that the formation of ectopic cartilage in acquired subglottic stenosis is not always due to a developmental aberration such as a hamartoma

Prevalence of permanent neonatal hearing impairment: systematic review and Bayesian meta-analysis

Objective: To investigate the variance in reported prevalence rates of permanent neonatal hearing impairment (HI) worldwide. Design: A systematic review and meta-analysis was performed on reported prevalence rates of sensorineural and permanent conductive or mixed HI worse than 40 dB in neonates, detected as a result of a screening programme or audiometric study. Study sample: For meta-analysis, 35 articles were selected, 25 from high-income countries and 10 from middle-income countries according to the world bank classification system. Results: The prevalence rate of permanent uni- and bilateral HI worse than 40 dB in neonates varied from 1 to 6 per 1000, the overall prevalence was 2.21 per 1000 [1.71, 2.8]. In NICU populations the prevalence rate was higher with a larger fraction of bilateral cases. Although not significant, prevalence rates were slightly higher in Asia compared to Europe and the number of infants lost to follow-up appeared higher in countries with lower gross national income. Conclusion: Substantial variations exist in prevalence rates of neonatal permanent HI across countries and regions. There is a strong need for more data from low-income countries to identify demographic factors that account for this variability in reported prevalence rates. Reporting these data in a uniform way is advocated
