The study of airways pH represents a new perspective in the comprehension of asthma pathogenesis. The effects of acidification may cause symptoms as cough, dyspnoea, wheezing and may be related to gastroesophageal reflux-induced asthma, inhaled acids (pollution, fog, professional exposure) and disregulation of acid-base homeostasis.

Gastric malrotation is defined as a torsion of stomach around its short or long axis. It is a rare disease in childhood. Gastric malrotation may present either as a surgical emergency or as chronic abdominal symptoms. There is limited data about the respiratory symptoms associated with gastric malrotation. The aim of this study was to review the records of 14 children who presented with respiratory symptoms and diagnosed as gastric organo-axial malrotation. Between August 2005 and August 2007, 14 children diagnosed as having gastric organo-axial malrotation participated in this study. There were 11 boys and three girls with a mean age of 7.1 months. All patients were symptomatic. Presenting symptoms included wheezing in four patients, recurrent pneumonia in four, chronic cough in two, chronic cough and apnea in two, recurrent pneumonia and chronic cough in one, and chronic cough and failure to thrive in one. All of our patients had organo-axial gastric malrotation. Gastroesophageal reflux was found in nine patients (64.2%). Six patients were treated with surgery and antireflux medication and the remaining eight patients with antireflux medication. In conclusion, it is probable that gastric malrotation associated with massive or occult gastroesophageal reflux could be responsible for the respiratory symptoms such as chronic cough, recurrent pneumonia, wheezing, and apnea.

Chronic cough is a major clinical problem. The causes of chronic cough can be categorized into eosinophilic and noneosinophilic disorders, the former being comprised of asthma, cough variant asthma (CVA), atopic cough (AC) and non-asthmatic eosinophilic bronchitis (NAEB). Cough is one of the major symptoms of asthma. Cough in asthma can be classified into three categories; 1) CVA: asthma presenting solely with coughing, 2) cough-predominant asthma: asthma predominantly presenting with coughing but also with dyspnea and/or wheezing, and 3) cough remaining after treatment with inhaled corticosteroid (ICS) and beta2-agonists in patients with classical asthma, despite control of other symptoms. There may be two subtypes in the last category; one is cough responsive to anti-mediator drugs such as leukotriene receptor antagonists and histamine H1 receptor antagonists, and the other is cough due to co-morbid conditions such as gastroesophageal reflux. CVA is one of the commonest causes of chronic isolated cough. It shares a number of pathophysiological features with classical asthma with wheezing such as atopy, airway hyperresponsiveness (AHR), eosinophilic airway inflammation and various features of airway remodeling. One third of adult patients may develop wheezing and progress to classical asthma. As established in classical asthma, ICS is considered the first-line treatment, which improves cough and may also reduce the risk of progression to classical asthma. AC proposed by Fujimura et al. presents with bronchodilator-resistant dry cough associated with an atopic constitution. It involves eosinophilic tracheobronchitis and cough hypersensitivity and responds to ICS treatment, while lacking in AHR and variable airflow obstruction. These features are shared by non-asthmatic eosinophilic bronchitis (NAEB). However, atopic cough does not involve bronchoalveolar eosinophilia, has no evidence of airway remodeling, and rarely progresses to classical asthma, unlike CVA and NAEB. Histamine H1 antagonists are effective in atopic cough, but their efficacy in NAEB is unknown. AHR of NAEB may improve with ICS within the normal range. Taken together, NAEB significantly overlaps with atopic cough, but might also include milder cases of CVA with very modest AHR. The similarity and difference of these related entities presenting with chronic cough and characterized by airway eosinophilia will be discussed.

Localized recurrent respiratory infections, leading to severe hypoxia in young children without immunological abnormalities or other risk factors, should raise the suspicion of airway structural abnormalities. In a 24-month-old boy, with recurrent severe post-viral wheezing and a history of RSV-induced bronchiolitis and gastro-esophageal reflux, fiberoptic bronchoscopy demonstrated an abnormal morphology of the distal portion of the trachea, ending in four openings. Computed tomography (CT) scans demonstrated the presence of a right tracheal bronchus and an anomalous upper lobar bronchus, originating at the level of the major carina.

Vocal cord dysfunction (VCD), is characterized by a paradoxical adduction of the vocal cords during inspiration, and occurs predominantly in young women. Common symptoms are cough, wheezing, episodic dyspnea, and inspiratory stridor. The true incidence and course of the disease are unknown, and it is usually self limited. It can coexist with, or mimic refractory asthma. Psychological disorders were thought to be the principal cause, subsequently multiple organic diseases have also been reported, like gastroesophageal reflux disease (GERD). Diagnosis is made by clinical suspicion and direct observation. The Gold standard for diagnosis is laryngoscopy with visualization of the paradoxical motion of the vocal cords when the patient is symptomatic. Speech therapy and psychotherapy have been used extensively without any prospective study. We report two cases of VCD associated with GERD, both with excellent respond to treatment.

In cases of recent asthma in which clinical control with the usual treatment (corticosteroids and bronchodilator) is unsatisfactory, it is important to consider other diagnoses, such as congestive heart failure, gastroesophageal reflux or other forms of airway obstruction. We report the case of a female patient with mucoepidermoid carcinoma of the trachea mimicking asthma. The patient presented cough and wheezing, as well as abnormal spirometry results with an obstructive pattern that was responsive to bronchodilators. One year later, the patient presented clinical and spirometric worsening. The chest X-ray revealed no abnormalities. A CT scan showed a vegetative lesion obstructing the tracheal lumen and located 1 cm from the carina. Fiberoptic bronchoscopy showed a finding similar to a bronchial carcinoid tumor. The anatomopathological diagnosis made after surgical resection was low-grade mucoepidermoid carcinoma, without lymph node involvement. Although the flow-volume curve was not suggestive of upper airway obstruction, the spirometry performed after the surgery showed a significant reduction in the degree of obstruction and greater reversibility after bronchodilator use. There was no evidence of recurrence of the disease or of the symptoms after a two-year follow-up period.

Gastroesophageal reflux disease (GERD) may cause, trigger or exacerbate many pulmonary diseases. The physiological link between GERD and pulmonary disease has been extensively studied in chronic cough and asthma. A primary care physician often encounters patients with extra esophageal manifestations of GERD in the absence of heartburn. Patients may present with symptoms involving the pulmonary system; noncardiac chest pain; and ear, nose and throat disorders. Local irritation in the esophagus can cause symptoms that vary from indigestion, like chest discomfort and abdominal pain, to coughing and wheezing. If the gastric acid reaches the back of the throat, it may cause a bitter taste in the mouth and/or aspiration of the gastric acid into the lungs. The acid can cause throat irritation, postnasal drip and hoarseness, as well as recurrent cough, chest congestion and lung inflammation leading to asthma and/or bronchitis/ pneumonia. This clinical review examines the potential pathophysiological mechanisms of pulmonary manifestations of GERD. It also reviews relevant clinical information concerning GERD-related chronic cough and asthma. Finally, a potential management strategy for GERD in pulmonary patients is discussed.

It is known that early childhood wheezing associated with sensitization to allergens, including food, has an increased risk of developing asthma later during school age. Gastroesophageal reflux (GER) is well known to be associated with asthma. The purpose of this study was to determine whether there is an association between silent GER and food sensitization in infants and young children with recurrent wheezing. Eighty-five infants or young children with recurrent wheezing, and no gastrointestinal symptoms, underwent 24 hr esophageal pH monitoring, as well as total serum IgE and specific IgE testing for eggs and milk. Among the 85 subjects, 48.2% had significant GER. There was no significant difference in the GER between atopic and non-atopic recurrent wheezers (41.7% and 50.8%, respectively). The sensitization rate to food (eggs or milk) was 12.2% and 20.5% in the GER and non-GER groups, respectively and showed no statistically significant difference between the two groups (P=0.34). In conclusion, about half of infants and young children with recurrent wheezing and no gastrointestinal symptoms have silent GER. The silent GER may not contribute to food sensitization in infants and young children with recurrent wheezing.

A joint study group on cow's milk allergy was convened by the Emilia-Romagna Working Group for Paediatric Allergy and by the Emilia-Romagna Working Group for Paediatric Gastroenterology to focus best practice for diagnosis, management and follow-up of cow's milk allergy in children and to offer a common approach for allergologists, gastroenterologists, general paediatricians and primary care physicians.The report prepared by the study group was discussed by members of Working Groups who met three times in Italy. This guide is the result of a consensus reached in the following areas. Cow's milk allergy should be suspected in children who have immediate symptoms such as acute urticaria/angioedema, wheezing, rhinitis, dry cough, vomiting, laryngeal edema, acute asthma with severe respiratory distress, anaphylaxis. Late reactions due to cow's milk allergy are atopic dermatitis, chronic diarrhoea, blood in the stools, iron deficiency anaemia, gastroesophageal reflux disease, constipation, chronic vomiting, colic, poor growth (food refusal), enterocolitis syndrome, protein-losing enteropathy with hypoalbuminemia, eosinophilic oesophagogastroenteropathy. An overview of acceptable means for diagnosis is included. According to symptoms and infant diet, three different algorithms for diagnosis and follow-up have been suggested.

Gastro-oesophageal reflux disease (GERD) is one of the most common clinical conditions in the developed countries. Particular interest in pulmonary manifestations of this disease has arisen over the last few years. Although the high coincidence between reflux and chronic cough is unquestioned, the proof of a causal correlation is still lacking. In this paper we present the Marburger Lung-Sound-Monitoring as a new method for the detection of nocturnal respiratory symptoms such as cough, wheezing and throat clearing and their temporal correlation with reflux. This method will in future allow us to precisely record and to evaluate the extent and duration of reflux events and their correlation with respiratory symptoms.
