This review discusses current general concepts on cough and the relationship between cough, cough receptor sensitivity, and asthma in children. It presents models of the relationship between cough and bronchoconstriction, and proposes a new model outlining the relationship between cough receptor sensitivity, airway hyperresponsiveness, and the clinical issues of cough, wheeze, and dyspnea in children with and without asthma. Cough is very common in children, with a prevalence of 15-20%. Those with non-specific cough (dry cough in the absence of identifiable respiratory illness) are often treated with a variety of drugs, in particular, medications for asthma and gastroesophageal reflux. However, there is little evidence to use these medications for the sole symptom of cough in children. Clinical studies on cough need to be interpreted in light of inherent methodological problems in studying cough. These methodological problems include the nonrepeatable nature of questions on cough, the unreliability of subjective measurements of cough, the lack of objective measurements to quantify cough severity, and the period effect (spontaneous resolution of cough). Although cough can be troublesome, cough serves as an important function for maintaining normal health of the respiratory system. The importance of cough in maintaining respiratory health is reflected in the development of lung atelactasis/collapse from retained secretions and recurrent pneumonia in clinical situations where the cough reflex is ineffective. The cough reflex is complex and still poorly understood. In this article the simplified cough pathway is presented and involves cough receptors, mediators of sensory nerves and the afferent pathway, the vagus nerve, the cough centre, efferent pathway, and cough effectors.

At present there is no test available which identifies children suffering from silent aspiration due to gastroesophageal reflux (GER). The purpose of this study was to determine whether lipid-laden alveolar macrophage (LLAM) scoring is a useful method to arrive at the diagnosis. We evaluated bronchoalveolar lavage fluid (BALF) from 68 children aged 6 months to 14 years (median 3.75 years) for the presence of lipid-laden alveolar macrophages. We compared children with chronic chest disease (CCD) and GER to healthy surgical controls without known lung disease, and to children with recurrent pneumonia without GER. By grading the amount of intracellular Sudan Red-positive material, we determined a semiquantitative lipid-laden macrophage (LLAM) score for each patient. Patients with chronic chest disease suspected to be caused by silent aspiration secondary to GER had a significantly higher LLAM score (median, 117; range, 10-956) than children with recurrent pneumonia due to other reasons (median, 29; range, 5-127; P < 0.01) and healthy controls (median, 37; range, 5-188; P < 0.01). We believe that simply observing lipid-laden macrophages is nonspecific, but quantitation of these cells is a useful method for diagnosing silent aspiration in children, especially when the score exceeds 200.

Gastroesophageal reflux disease (GORD) is more frequent among people with intellectual disability than among the intellectually normal population. Also GORD is more serious in this population. The diagnosis is often missed, because most intellectually disabled cannot express their complaints of GORD. For that reason a multidisciplinary working group of the Dutch Association of physicians active in the care of persons with a mental handicap has developed guidelines. The working group recommends endoscopy in case of a (alarm) symptoms: haematemesis, prolonged vomiting, irondeficiency anaemia e.c.i., and a 24 hour oesophageal pH test in case of b (aspecific) symptoms: recurrent pneumonia, refusal of food, regurgitation, rumination, dental erosions. In general most patients are cured with drug treatment (omeprazol or another proton pump inhibitor). If symptoms are not improved after 6 months of optimal treatment, surgical treatment may be considered.

Laryngopharyngeal sensory testing can predict aspiration risk in adult patients. Its feasibility and potential role in the evaluation of pediatric swallowing is undetermined. The goals of this study were to determine the feasibility of performing laryngopharyngeal sensory testing in awake pediatric patients and to assess whether the sensory testing results correlated with aspiration during a feeding assessment or correlated with a history of pneumonia. Fiberoptic endoscopic evaluation of swallowing with sensory testing was performed in 100 pediatric patients who were evaluated for feeding and swallowing disorders. The swallowing function parameters evaluated were pooled secretions, laryngeal penetration, and aspiration. The laryngopharyngeal sensory tests were performed by delivering a pressure-controlled and duration-controlled air pulse to the aryepiglottic fold through a flexible laryngoscope to induce the laryngeal adductor response (LAR). The air pulse stimulus ranged in intensity from 3 to 10 mm Hg. The patients tested ranged from 1 month to 24 years of age, with a median age of 2.7 years. Sensory testing was completed in 92% of patients. Patients who had an LAR at less than 4 mm Hg rarely if ever had episodes of laryngeal penetration or aspiration. Those with an LAR at 4 to 10 mm Hg had variable amounts of aspiration and laryngeal penetration. The LAR could not be elicited at the maximum level of intensity (10 mm Hg) in 22 patients, who demonstrated severe laryngeal penetration and/or aspiration. Elevated laryngopharyngeal sensory thresholds correlated positively with previous clinical diagnoses of recurrent pneumonia, neurologic disorders, and gastroesophageal reflux, and correlated positively with findings of pooled secretions, laryngeal penetration, and aspiration. Laryngopharyngeal sensory testing in children is feasible and correlative.

Gastroesophageal reflux disease (GERD) can present with both typical symptoms such as heartburn and regurgitation as well as atypical symptoms. These symptoms may include chest pain, asthma, chronic cough, hoarseness, otitis media, atypical loss of dental enamel, idiopathic pulmonary fibrosis, recurrent pneumonia, chronic bronchitis and even sudden infant death. The diagnosis of GERD in these patients can often present a challenge and usually requires a combination of selected testing and therapeutic trials. Acid suppression by using proton pump inhibitors remains the treatment of choice in GERD, but some patients will also respond well to antireflux surgery. This article addresses the presentations, diagnostic challenges, and therapeutic opportunities in GERD patients with atypical presentations.

Gastroesophageal reflux disease can result in such supraesophageal complications as hoarseness, sore throat, cough, bronchitis, asthma, recurrent pneumonia, intermittent choking, chest pain, and ear pain. Appropriate patient care involves careful evaluation to decide on medical or surgical therapy. Preoperative testing must include endoscopy, 24-hour esophageal pH monitoring, and esophageal manometry. Additional evaluations, such as barium swallow, chest x-ray, bronchoscopy, and sinus radiographs, may be required. Medical treatment improves gastroesophageal reflux and supraesophageal symptoms. However, surgical therapy seems to provide better long-term results. A profile that predicts the best response to medical therapy has not been identified, although the best results with surgery are achieved in patients with nocturnal asthma, onset of reflux before pulmonary symptoms, laryngeal inflammation, and a good response to medical treatment.

An 85-year-old woman was receiving enteral feeding via percutaneous endoscopic gastrostomy (PEG). The patient exhibited symptoms of gastro-esophageal reflux, leakage of nutrient from the PEG insertion point, vomiting, pyrexia, dyspnea when given nutrients and recurrent pneumonia. We therefore gave a half-solid nutrient, which was made by a mixture of agar powder and conventional liquid nutrient Immediately after starting the half-solid nutrient feeding via PEG, the patients no longer exhibited the above symptoms apart from mild pyrexia, which also vanished two weeks later. This case suggested that simply changing the fluidity of nutrients can contribute to a reduction of complications expected to occur in patients on PEG tube feeding.

We reviewed our experience in the diagnosis and management of esophageal achalasia in 33 children over a 25-year period at a single center by a retrospective chart review of all patients diagnosed with achalasia between December 1, 1975 and January 30, 2001. There were 33 cases ranging from 5 months to 16 years of age at the time of presentation (17 boys and 16 girls). Although dysphagia and vomiting were the commonest presenting symptoms, weight loss, chest pain, coughing, and recurrent pneumonia also occurred in many patients. Barium contrast study of the esophagus was the initial diagnostic modality followed by esophageal manometry. An upper endoscopy was also performed in 78.7% of cases. Management was predominantly surgical; however, seven recently diagnosed patients opted for botulinum toxin (botox) injection as the first line of treatment. The follow-up duration varied from 10 months to 10 years (mean 4.71 +/- 3.2 years). Postsurgical complications included gastroesophageal reflux disease in five patients who had not received a simultaneous antireflux procedure and "residual achalasia" in two patients, who both responded to a single botox injection.

Acid reflux--most often associated with heartburn--may also cause a wide range of laryngopharyngeal symptoms, including laryngitis and chronic cough. Symptoms of laryngopharyngeal reflux (LPR), like those of gastrooesophageal reflux disease, result from abnormal exposure of tissues to acid refluxate. Deranged sensorimotor function of the upper oesophageal sphincter appears to play a key role in the aetiology of LPR, but the disease is not completely understood. Among the significant long-term complications of LPR are bronchopulmonary disorders, recurrent pneumonia, chronic cough, chronic or recurrent laryngitis, and oral cavity disorders. It also appears to be a risk factor for the development of laryngeal carcinoma. Diagnosis of LPR is based on physical examination, medical history, and results of specific tests. At present, the test of choice for LPR diagnosis is intraluminal oesophageal pH monitoring. Barium contrast oesophagography, intraoesophageal acid perfusion challenge, and flexible endoscopic evaluation of swallowing with sensory testing may also be used in LPR diagnosis. Treatment for LPR includes changes to the diet and lifestyle, and acid-suppressing therapy. The Therapeutic Working Party at the First Multi-Disciplinary International Symposium on Supraesophageal Complications of Gastroesophageal Reflux Disease has recommended twice-daily dosing with a proton pump inhibitor as an initial therapy for LPR, with treatment continued between 4 weeks and 6 months. Such treatment has been found highly effective in resolving symptoms of LPR, and it may also prevent the serious long-term complications of this condition.

Gastroesophageal reflux (GER) occurs throughout the day in healthy infants, children, and adolescents, as well as in adults. However, regurgitation into the pharynx and vomiting are more common in infants than in adults. This places the infant at particular risk for supraesophageal complications of GER. Despite recognition of this risk, a lack of good control data in children and an absence of placebo-controlled treatment trials provide only marginal evidence to support GER as a cause of any supraesophageal disorder in infants or children. An association of GER with "awake apnea," reactive airway disease, and recurrent pneumonia has been demonstrated. Although there is no good evidence to support the efficacy of medical therapy, surgical therapy for GER has been demonstrated to improve symptoms in selected cases with each of these symptom presentations. Although clinical experience and case series suggest that GER may possibly contribute to laryngeal disorders, sinusitis, and otitis media, convincing data are lacking. No studies have definitively demonstrated symptom improvement with medical or surgical therapy for the latter symptom presentations.
