This case illustrates an unusual cause of respiratory distress in the pediatric population. A high degree of suspicion is necessary to make the diagnosis of plastic bronchitis. Wheezing and cough will lead to the diagnosis of reactive airway disease and/or foreign body aspiration. Chest radiographs may yield additional information, but the diagnosis is made by bronchoscopy and removal of the casts. Any child with severe respiratory distress refractory to aggressive conventional medical therapy and with a history or radiograph suggestive of plastic bronchitis should be considered a candidate for bronchoscopy. As clinicians, we must always remember the dictum, "All that wheezes is not asthma."

A retrospective analysis of records from an outpatient medical practice was undertaken to determine the incidence and features of cough resulting from the use of enalapril maleate. Of 209 patients taking enalapril, 22 (10.5%) required discontinuation of therapy because of an intractable, dry cough. Cough was more than twice as common in women; 16 (14.6%) of 109 women and 6 (6%) of 100 men stopped taking enalapril because of cough. The cough resolved in 21 of 22 patients within 2 weeks of discontinuation of enalapril therapy. When the patients with cough were compared with the others, there was no significant difference in age, smoking status, creatinine levels, enalapril dosage, associated cardiopulmonary disease, or concomitant administration of medications. Among the 187 study patients who did not discontinue taking enalapril because of cough, many developed a persistent, dry cough that to date has not been severe enough to require discontinuation of therapy, after a mean follow-up period of 16 months. The enalapril-induced cough is insidious, dry, persistent, benign, and reversible on discontinuation of therapy. It is important to distinguish enalapril-induced cough from cough resulting from acute illness, reactive airway disease, and congestive heart failure. Optimal clinical application of enalapril in the treatment of hypertension and congestive heart failure will require increased awareness of this incessant cough, which requires discontinuation of the therapy in about 10% of patients.

Twenty cases of laryngotracheal foreign bodies were reviewed over an 11-year period to determine features that differentiate these from bronchial foreign bodies. A history of choking or aspiration was obtained in 18 patients (90%). The most common presenting symptoms were stridor, wheezing, sternal retractions, and cough. The chest roentgenogram was most often normal (58% [11/19]). Posteroanterior and lateral neck roentgenograms suggested the diagnosis in 92% (12/13) of the patients. The correct diagnosis was made within the first 24 hours of presentation in 11 patients (55%); 19 patients (95%) were correctly diagnosed within one week. The incidence of major complications was 45% (9/20); however, in patients with a delay in diagnosis of over 24 hours the complication rate was 67% (6/9). For this reason, in children with a diagnosis of croup or reactive airway disease who respond poorly or whose condition deteriorates despite appropriate medical therapy, early endoscopy should be considered.

Sinus disease has been described as one of several aggravating factors for chronic adult-onset asthma. Forty-eight children whose reactive airway disease (asthma) was significantly improved with treatment of their sinusitis have been observed. All of the subjects were seen in the office with chronic (more than 3 months) respiratory symptoms; all had daytime and nighttime cough and/or wheeze. The 48 children (32 male and 16 female) had a mean age of 8.2 +/- 1.2 (SD) years (range 4 to 13 years). Fourteen (35%) were nonatopic as determined by family history, personal history, and skin test reactivity to inhalant and pollen antigens. Eighteen of the patients were receiving or had recently received oral corticosteroids. All had been taking bronchodilators daily for at least 3 months without adequate control of the asthma. Sinus radiographs (Waters view) revealed the following abnormalities of the maxillary sinuses: greater than 6 mm of mucosal thickening (ten children [21%]), one opacified (12 children [25%]), bilateral opacification (18 children [38%]) and air fluid level(s) (eight children [17%]). All children were treated with antimicrobial agents for 2 to 5 weeks. Thirty-nine responded both clinically and radiologically. Antral lavage was performed in nine children. Of the 48 subjects, 38 (79%) were able to discontinue taking the bronchodilators with resolution of their sinusitis. It is concluded that sinus disease in children may be an aggravating factor for chronic reactive airway disease and that proper, aggressive treatment of the former will notably improve the latter.

The use of a laryngeal mask airway (LMA) and a bi-level positive airway pressure (BiPAP) machine is described in a post-operative thoracotomy patient with reactive airway disease. The LMA was placed to avoid reintubation of the trachea after a double lumen tube was no longer necessary. Placement in an awakening patient and positive-pressure ventilatory support were well tolerated and did not trigger a bronchospastic response. The patient was able to cough and breathe deeply with the LMA while receiving ventilatory assistance in the post-anaesthesia care unit (PACU). The LMA is a therapeutic option to tracheal reintubation in patients who need postoperative ventilatory support after one-lung anaesthesia.

A comparison study was made between attitudes of asthmatic and nonasthmatic adolescents toward cigarettes and smoking. Subjects were 67 asthmatic 9th- to 12th-grade students, of whom 38 (57%) had active asthma with recurrent cough and/or dyspneic attacks and 29 (43%) had reactive airway disease and/or the least severe form of asthma expressed by recurrent cough. The control group included 62 nonasthmatic students from the same high school. All subjects completed a questionnaire to determine attitudes, beliefs, and intentions regarding smoking. Their responses suggested that the group at highest risk of becoming smokers were those who had previously had asthma. The same adolescents had a more positive attitude toward cigarettes and smoking, a stronger intention to become smokers, and a self-image more closely linked with their perceptions of smokers. Thus, these adolescents may represent a high-risk group for becoming smokers in the future.

Forty children aged between 3 months and 3 years (median age 14 months) with persistent respiratory symptoms beyond 4 weeks or recurrence of respiratory symptoms were investigated for gastroesophageal reflux (GER). Diagnostic tests included upper gastrointestinal endoscopy, oesophageal biopsy, gastroesophageal scintiscan and 24 h ambulatory oesophageal pH monitoring. GER was detected in 14 (35 per cent) of these patients; which included 38 per cent of the enrolled cases of recurrent bronchopneumonia, 40 per cent cases of reactive airway disease, and 22 per cent cases of persistent cough. Amongst the cases detected to have GER, the age of onset of respiratory symptoms was less than 1 year in 86 per cent of cases (p < 0.01), nocturnal symptoms of cough and wheeze were reported in 78 per cent (p < 0.05), and 86 per cent cases did not present with typical gastrointestinal symptoms (p < 0.01). Family history of asthma was absent in all cases of GER-related reactive airway disease (p < 0.01). Cases detected to have GER were followed for 3-6 months after starting anti-reflux therapy. A significant (p < 0.01) decrease was noticed in the number of further episodes in children with GER-related recurrent bronchopneumonia and reactive airway disease after starting anti-reflux therapy. Improvement was also noticed in nocturnal symptoms and nutritional status after anti-reflux therapy was started. Our results suggest that GER may be one of the possible contributing factors in any child with recurrent and persistent respiratory complaints. Early diagnosis and anti-reflux therapy in cases with GER-related respiratory complaints can result in significant improvement in symptoms.

Infants often develop reactive airway disease after respiratory syncytial virus (RSV) bronchiolitis. Cysteinyl-leukotrienes (cys-LT) are released during RSV infection and may contribute to the inflammation. We hypothesized that a cys-LT receptor antagonist would ameliorate reactive airway disease subsequent to RSV bronchiolitis. One hundred and thirty infants who were 3 to 36 months old, hospitalized with acute RSV bronchiolitis, were randomized into a double-blind, parallel comparison of 5-mg montelukast chewable tablets or matching placebo given for 28 days starting within 7 days of symptom debut. Infants with a suspected history of asthma were excluded. One hundred sixteen infants provided diary card data for the treatment period. Median age was 9 months. Infants on montelukast were free of any symptoms on 22% of the days and nights compared with 4% of the days and nights in infants on placebo (p = 0.015). Daytime cough was significantly reduced on active treatment (p = 0.04). Exacerbations were significantly delayed from montelukast compared with placebo (p < 0.05). In conclusion, cys-LT antagonist treatment reduces lung symptoms subsequent to RSV bronchiolitis.

A young, otherwise healthy man had chronic cough of 16 months' duration. Evaluation revealed an aberrant right subclavian artery. Kommerell's diverticulum without aneurysmal degeneration was present. Imaging studies showed compression of the esophagus but not the trachea. Results of methacholine challenge test were negative for evidence of reactive airway disease, but suggested mild variable intrathoracic obstruction. While aberrant right subclavian artery syndrome most commonly involves dysphagia, our patient's only symptom was cough. Right subclavian artery to right common carotid artery transposition was performed, with oversewing of the subclavian artery stump to the left of the esophagus through a right supraclavicular incision. This treatment was curative, with complete resolution of symptoms.

Obstructive sleep apnea (OSA) occurs commonly in the U.S. population and is seen in both obese as well as non-obese individuals. OSA is a disease characterized by periodic upper airway collapse during sleep, which then results in either apnea, hypopnea, or both. The disorder leads to a variety of medical complications. Neuropsychiatric complications include daytime somnolence, cognitive dysfunction, and depression. Increased incidence of motor vehicle accidents has been documented in these patients and probably reflects disordered reflex mechanisms or excessive somnolence. More importantly, vascular disorders such as hypertension, stroke, congestive cardiac failure, arrhythmias, and atherosclerosis occur frequently in these patients. The lungs may be affected by pulmonary hypertension and worsening of asthma. Recent data from several laboratories demonstrate that obstructive sleep apnea is characterized by an inflammatory response. Cytokines are elaborated during the hypoxemic episodes leading to inflammatory responses as marked clinically by elevated C-reactive protein (CRP). As elevated CRP levels are considered markers of the acute phase response and characterize progression of vascular injury in coronary artery disease, it is likely that obstructive sleep apnea could lead to worsening of vasculopathy. Moreover, as inflammatory mechanisms regulate bronchial asthma, it is also likely that cytokines and superoxide radicals generated during hypoxemic episodes could exacerbate reactive airway disease. Patients with Cough, Obstructive sleep apnea, Rhinosinusitis, and Esophageal reflux clustered together can be categorized by the acronym, "CORE", syndrome. The purpose of this manuscript is to review the inflammatory responses that occur in patients with obstructive sleep apnea and relate them to the occurrence of cardiopulmonary disease.
