Tracheopulmonary aspiration is a common occurrence in patients with dysphagia associated with head and neck cancer. We performed quantitative scintigraphic analysis of tracheopulmonary aspiration in 125 patients with head and neck cancer; 58 of these patients had a tracheostomy. Tracheopulmonary aspiration occurred in 58% of patients with a tracheostomy and in 23% of patients without a tracheostomy. In six of seven patients with a tracheostomy, tracheopulmonary aspiration significantly increased when the obturator was removed and, in these patients, occlusion of the tracheostomy tube during feedings eliminated or reduced the complication. Our studies suggest that aspiration can be monitored accurately and conveniently by scintigraphy, and that this technique is useful in the evaluation and management of dysphagia in debilitated patients.

Myiasis; is defined as the infestation of dead or living tissues of humans and animals by the diptera larvae. It is prevalent all over the world, especially in tropical and subtropical countries with low socioeconomic status. Myiasis of humans has been associated with low socioeconomic status, alcoholism, mental or neurological diseases, poor personal hygiene, patients with varicose veins, diabetes, malnutrition, advanced stage cancer, pediculosis, immunosuppression, sexually transmitted disease, gingivitis and other oral cavity lesions.

Objective: To review current understanding and approach to diseases resulting from gastroesophageal reflux (GER) in infants and children.
Quality Of Evidence: Very few randomized or blinded controlled trials have been reported in this area. MEDLINE searches for gastroesophageal reflux, gastroesophageal reflux disease, esophagitis, and pulmonary aspiration, using age-limited (all childhood) data, find most articles.
Gastroesophageal reflux disease (GERD) accompanied by regurgitation and aspiration has been suggested as the cause of many conditions, but the strongest evidence exists for a relationship between asthma and GERD and posterior laryngitis and GERD. The exact mechanism of the tracheopulmonary damage has not been determined, but studies show that proton pump inhibitor therapy can ameliorate to some extent the laryngeal symptoms in laryngitis as well as asthma symptoms, asthma medication use, and lung function. Antireflux surgery appears to be more effective than antireflux medication in asthma patients with GERD symptoms.

The aspiration of different substances into the airways and lungs may cause a variety of pulmonary complications. These disease entities most commonly involve the posterior segment of the upper lobes and the superior segment of the lower lobes. Esophagography and computed tomography (CT) are especially useful in the evaluation of aspiration disease related to tracheoesophageal or tracheopulmonary fistula.
