Abstract

Percutaneous needle tracheostomy and transtracheal ventilation continues to be advocated for the management of upper airway obstruction. Recent studies recommend the use of artificial ventilation. However, as apparatus for this is not always available and because there remains some doubt regarding conditions for successful use of needle tracheostomy during spontaneous respiration, we undertook such a study in dogs. Pressure-flow characteristics of short hollow needles 18-10 SWG were first determined. The smallest of these (14 SWG Bardic Intracath) that would deliver flow sufficient (by calculation) to meet the respiratory requirement of 10-13 kg laboratory dogs was selected for further study. Respiration was possible by spontaneous or artificial methods in the presence of complete tracheal occlusion. Little or no deterioration was noted in an hour of such breathing. Artificial ventilation by machine and by hand could considerably lower PaCO2. We conclude that the technique is possible provided appropriate needles are selected and care is given to their method of use.

Thyroid involvement with Langerhans cell histiocytosis in a 3-year-old male.

We report on the thyroid involvement with Langerhans cell histiocytosis (LCH) in a 3-year-old male. The patient presented with goiter and primary hypothyroidism. His goiter caused life-threatening airway obstruction. He developed locally invasive disease 4 years after his response to LCH therapy. LCH should be suspected as a cause of goiter and thyroidectomy is recommended.

Potential mechanisms connecting asthma, esophageal reflux, and obesity/sleep apnea complex--a hypothetical review.

Obstructive sleep apnea (OSA) and asthma are potentially linked at several levels. The pathophysiology of these two conditions seems to overlap significantly, as airway obstruction, inflammation, obesity, and several other factors are implicated in the development of both diseases. Gastroesophageal reflux disease (GERD), cardiovascular complications, obesity itself, and the underlying inflammatory processes are all complex contributory factors that provide hypothetical links. Furthermore, a collateral rise in prevalence of both OSA and asthma has been noticed during the past few years, occurring in association with the emerging epidemic of obesity, a common risk factor for both conditions. OSA and asthma share many other risk factors as well. We propose a hypothetical OSA-asthma relationship that has implications on the diagnosis and management of patients presenting with either condition singly. Clinicians should be aware that OSA might complicate asthma management. Based on this hypothesis, we suggest that the treatment of the individual patient who experiences both asthma and OSA needs to be multidisciplinary and comprehensive. This hypothetical association of asthma and OSA, though described anecdotally, has not been systematically studied. In particular, the influence of continuous positive airway pressure therapy (for sleep apnea) on asthma outcomes (such as quality of life, steroid utilization, emergency room visits) and fatality needs to be studied further.

Managing isolated subglottic juvenile xanthogranuloma without tracheostomy: case report and review of literature.

Juvenile Xanthogranuloma (JXG) is a dendritic cell related histiocytic disorder which usually presents in the first year of life as a solitary cutaneous granuloma. Isolated presentation in the upper airway is very rare but can result in severe respiratory distress, especially in young children. We present the case of a 5-month-old male with an isolated subglottic JXG lesion. Endoscopic excision provided symptomatic relief and avoided the need for tracheostomy. The lesion has completely resolved 17 months later. Surgical excision without tracheostomy was the treatment of choice in two of the four additional cases of upper airway JXG presented in the literature. JXG has an excellent prognosis with spontaneous regression over time. Histology alone is frequently inadequate to differentiate JXG from the more common Langerhans Cell Histiocytosis (LCH), which carries a much less favorable prognosis. The evolving field of immunohistochemistry provides an essential tool to establish the correct diagnosis. The typical phenotype of JXG is Factor XIIIa+/Fascin+/CD68+/CD163+/CD14+/CD1a-/S100-.
