Both upper and lower respiratory tracts can be affected by food allergy. Manifestations in either may be exclusively due to food allergy (common in infants) or may result from the combined effects of food allergy plus another defect such as gastroesophageal reflux, a congenital defect of the heart or tracheo-bronchial tree, an immunodeficiency syndrome such as isolated IgA or IgG4 deficiency, or a concomitant inhalant allergy. Chronic rhinitis is the most common respiratory tract manifestation of food allergy. When it occurs in conjunction with lung disease, it may be a helpful indicator of activity of the allergic lung disease and of the patient's compliance in following a specific diet. Recurrent serous otitis media may be solely or partially due to food allergy. Large tonsillar and adenoid tissues, sometimes with upper airway obstruction, may be caused, or aggravated by, food allergies. Lower respiratory tract disease manifested by chronic coughing, wheezing, pulmonary infiltrates, or alveolar bleeding may also occur. Lower respiratory tract involvement is generally associated with a greater delay in onset of symptoms and with a larger quantity of allergen ingestion than chronic rhinitis. Food allergy should be considered when there is a history of prior intolerance to a food in childhood or of symptoms beginning soon after a particular food was introduced into the diet. It is an important consideration in patients who have chronic respiratory tract disease which does not respond adequately to the usual therapeutic measures and is otherwise unexplained.(ABSTRACT TRUNCATED AT 250 WORDS)

The high incidence of pneumopathy in intensive care units might be due to the pulmonary aspiration of gastric juice following gastro-oesophageal reflux. The paper describes a radio-isotopic method using material easy to install at the patient's bedside. This technique demonstrated aspiration of gastric juice in the lungs of 8 of 25 intensive care patients investigated. Such a method might be useful later to demonstrate that silent bronchial aspirations of gastric juice are responsible for pulmonary complications.

The high incidence of respiratory symptoms in patients with reflux esophagitis reported in the literature supports a cause-effect relationship between esophageal reflux and pulmonary symptoms. Analysis of the results of routine preoperative pulmonary function tests on 90 patients with reflux esophagitis and on 277 patients having nonthoracic elective surgery revealed that although the incidence of obstructive lung disease was high in both groups, it was higher in the general surgical population (51.9%) than in the patients with reflux esophagitis (37.7%). Thus a cause-and-effect relationship cannot be established between reflux esophagitis and obstructive lung impairment. This study indicates that the incidence of significant obstructive lung impairment in the general surgical population is greatly underestimated.

Congenital diaphragmatic hernia (CDH) has been associated with a high mortality rate. The purposes of this study were to determine the impact of extracorporeal membrane oxygenation (ECMO) on the survival of infants with CDH and to document the sequelae and 1-year neurodevelopmental outcome for CDH infants who required ECMO. Thirty neonates with CDH were admitted between May 7, 1990 and October 1, 1992. Twenty required ECMO and were enrolled in our neonatal follow-up program. Information about the infants' neonatal course was obtained from chart review, and the infants were seen at 3, 6, and 12 months of age for medical and neurodevelopmental follow-up. Primary diaphragmatic repair was performed in 13 infants. Five required Goretex graft reconstruction (GGR), and two did not have repair. Sixteen (80%) of the 20 infants who required ECMO survived. The overall survival rate increased from 31% (10 of 32) in the 5 years previous to the start of the ECMO program to 63% (19 of 30) since then (P = .01). The most common sequelae noted by the time of discharge included gastroesophageal reflux (GER; 81%), the need for tube feeding (69%), and chronic lung disease (CLD; 62%). At 1 year of age, mean cognitive skills were average (87 +/- 23) and motor skills were borderline (75 +/- 24) according to the Bayley Scales of Infant Development. Hypotonia was present in 10 of 13 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a unique case of coexisting exogenous lipoid pneumonia, endogenous lipoid pneumonia (ELP), and pulmonary alveolar proteinosis (PAP) in a 5-year-old patient with severe neurodevelopmental disease. The patient presented with gastroesophageal reflux and presumed chronic lung disease resulting from recurrent aspiration pneumonias and succumbed to respiratory failure. The autopsy showed lipid-laden macrophages and periodic acid-Schiff-positive granular material in alveolar spaces and multilamellated structures within both alveolar macrophages and extracellular debris. These findings were similar to those in previous reports of coexisting ELP and PAP in the setting of gastroesophageal reflux. However, the present case differed by the presence of scattered large osmiophilic extracellular lipid vacuoles. Besides strengthening the association between ELP and PAP and their relationship to gastroesophageal reflux, this case suggests that they may arise together with exogenous lipoid pneumonia, through related mechanisms, in the setting of neurodevelopmental disease.

Five patients in a pediatric population were identified with idiopathic follicular bronchitis (IFB) by open lung biopsy and their case records were reviewed. All were tachypneic and had a chronic cough by 6 weeks of age. The physical examination was characterized by diffuse fine crackles in four patients and by coarse rhonchi in one. The chest radiographs in all demonstrated a diffuse interstitial pattern. None had a collagen vascular or an autoimmune disease demonstrable. Response to corticosteroid therapy was minimal. Associated or coincidental esophageal reflux was treated surgically in two. No viral or bacterial agents were isolated in the sputum or the biopsy specimens. Patients have been followed up for 2 to 15 years; the conditions of all patients improved at about 2 to 4 years of age. The older patients have residual mild obstructive lung disease. To our knowledge, this is the first reported series of IFB in the pediatric population.

Nebulized recombinant human DNase (rhDNase) reduces sputum viscosity, improves pulmonary function, and results in a small reduction in acute respiratory exacerbations requiring intravenous antibiotics in many patients with cystic fibrosis (CF). rhDNase is now recommended for use in CF patients with moderately severe suppurative lung disease. A 14-year-old girl with suppurative lung disease [forced expiratory volume in 1 second (FEV1) 69% and forced vital capacity (FVC) 81% predicted] secondary to Kartagener's syndrome and severe gastroesophageal reflux had worsening spirometry together with intractable gastrointestinal symptoms over the previous 18 months despite conventional treatment. She was, therefore, started on 2.5 mg rhDNase once daily. Her cough lessened and the volume of sputum decreased within 72 hours of commencement of treatment; this improvement was strongly associated with a dramatic reduction in gastrointestinal symptoms. Spirometry after 4 weeks of treatment demonstrated a 20% improvement in FEV1 and a 13% improvement in FVC. These improvements have been maintained after 4 months of rhDNase therapy. The use of rhDNase should be considered in patients with Kartagener's syndrome and a multicenter trial may be justified.

Cough is one of the commonest symptoms of lung disease and is a frequent problem encountered in general practice as well as in hospital practice. A wide range of disease processes may present with cough and definitive treatment depends on making an accurate diagnosis of the cause. A diagnostic work-up for patients with persistent dry cough is presented. The most common associated conditions are post-viral cough, asthma, rhinosinusitis (post-nasal drip or 'nasal catarrh') and gastro-oesophageal reflux. Treatment with angiotensin-converting enzyme inhibitors can also lead to a persistent dry cough. Specific treatment of the cause should control the cough, but this may not occur in all cases and in a sizeable proportion of patients, no associated cause can be found. An increased sensitivity of the cough reflex can be observed in patients with persistent dry cough. Symptomatic relief must be considered when the cough interferes with the patient's health and sleep but the most effective antitussive opiates cause sedation and may be addictive. Treatment of persistent dry cough remains a challenge in some patients and there is still scope for improvement in its diagnosis and effective therapy.

Gastro-oesophageal reflux (GOR) has been implicated in the aetiology of lung disease. Cystic fibrosis (CF) patients have a high incidence of GOR symptoms with demonstrable episodes of oesophageal acidification. We studied 24-hour ambulatory tracheal and oesophageal pH in 11 CF patients with GOR symptoms to identify any episodes of tracheal acidification and define their temporal relation to oesophageal reflux and respiratory symptoms. 8 patients had evidence of significant GOR (DeMeester score mean 58; range 17-107) and in 6 it was gross (DeMeester score > 30). 4 patients had tracheal acidification (defined as tracheal pH < 5.5): all had greatly raised DeMeester scores. Two patterns of lowered tracheal pH were seen: a gradual drift downwards of tracheal pH to < 5.5 which recovered slowly, and an acute fall in tracheal pH to < 5.5 with rapid recovery. Only one patient had a fall in peak expiratory flow in conjunction with a decline in tracheal pH, and no association was found between the presence of tracheal microaspiration and pulmonary function. We conclude that tracheal acidification occurs in adult CF patients with GOR.
