Interstitial lung diseases (ILD) are disorders of the lower respiratory tract, characterized by chronic inflammation of the lung parenchyma, varying degree of fibrosis, derangement of the alveolar walls and loss of the functional alveolar capillary units. ILD are relatively uncommon in children. Most of the interstitial lung diseases have no known etiology. In children, common diseases associated with ILD include viral respiratory tract infections (RSV, parainfluenza, etc.), gastroesophageal reflux, idiopathic pulmonary fibrosis, pulmonary hemosiderosis, eosinophilic pneumonia, pneumonitis associated with AIDS, etc. Chronic inflammation of the alveoli (alveolitis), the initial injury in ILD, and several mediators released from inflammatory cells (eosinophils, neutrophils and macrophages) can cause fibrosis and derangement of alveolar walls. Dyspnea and a non-productive cough are the cardinal symptoms of ILD. Other findings include chest pain, hemoptysis and weight loss. Clubbing of fingers occur in approximately 50 per cent of cases. Diagnosis is based on a combination of history, clinical findings, radiographic findings, pulmonary function tests and histologic findings. Open lung biopsy has been very helpful in providing information regarding the extent and nature of the damage, prognosis and response to therapy. There are 3 main aspects in the treatment of ILD. The most important step is to identify and eliminate the cause. The second is suppression of the inflammation. The third is supportive and symptomatic treatment. Corticosteroids are the drugs commonly used for suppression of inflammation. Immunosuppressive drugs (azathioprine, cyclophosphamide) have also been tried. Lung transplantation and heart transplantation have been successfully achieved in selected patients. The results of therapy should be regularly monitored by clinical symptoms, chest radiographs and serial pulmonary function studies.

A 15-year-old girl was referred with a 2-year history of perennial non-productive cough, which had been preceded by Mycoplasma pneumoniae pneumonia and subsequent asthma. Symptoms were only partially responsive to anti-asthma treatment including an inhaled corticosteroid and a leukotriene receptor antagonist. The patient's BMI was 27.8; she had gained over 10 kg in the previous two years. Typical symptoms of gastroesophageal reflux disease were not evident except for belch. Coughing worsened on eating and rising from bed. Although esophagography failed to disclose reflux esophagitis, esophageal pH monitoring revealed significant acid reflux. Asthma was considered well controlled. Treatment with the proton-pump inhibitor rabeprazole resulted in disappearance of cough. Frequency Scale for the Symptoms of Gastroesophageal reflux disease (FSSG) score, a questionnaire evaluating the symptoms of gastroesophageal reflux disease, was initially high but normalized after treatment. Capsaicin cough sensitivity also diminished with treatment.Chronic cough due to gastroesophageal reflux disease has been considered rare in adolescents, but this condition might be increasing in line with the recent trend in adults. Clinical features of gastroesophageal reflux disease-associated cough typical for adult patients and a specific questionnaire for evaluating gastroesophageal reflux disease validated in adults may also be useful diagnostic clues in adolescents.

The review presents an update on the determination of the causes and mechanisms of acute and chronic cough. It assesses the concept of productive and non-productive cough (acute cough, chronic cough), its duration in different diseases of the lung, upper and lower respiratory tract, pulmonary embolism, gastroesophageal reflux disease, pharyngolaryngeal reflux, and during treatment with angiotensin-converting enzyme inhibitors. Information is given on treatment policy for cough in different diseases.

Chronic cough that is dry, non-productive and without constitutional symptoms is often thought to have a non-malignant etiology such as asthma, post-nasal drip or gastroesophageal reflux disease (GERD). We present a case of a patient with a 3 year history of 'chronic cough' that was dry, non-productive cough and without any constitutional symptoms. Initial chest x-ray (CXR) done 3 years ago showed some streaky atelectasis in the right middle lobe along with some volume loss on that side. Another CXR performed one and half years later showed progression to a complete right middle lobe collapse. She ultimately presented to our facility a year later with stable CXR findings, but persistent cough. A chest CT scan was suspicious for a right lower lobe mass. A PET scan subsequently confirmed a hypermetabolic right hilar mass causing extrinsic compression of the bronchus intermedius. She ultimately required a complete right pneumonectomy with partial pericardiectomy and had complete resolution of her cough. This case highlights the fact that 'chronic cough' should always be thoroughly investigated and should remain a diagnosis of exclusion until all sinister pathologies have been ruled out.

Bronchiectasis is a chronic lung disease with permanent airway dilatation, mucus retention and recurrent lower respiratory tract infections. Bronchiectasis is increasing in prevalence and has a significant morbidity and an excess mortality rate over age matched controls. It is increasingly identified during investigations into chronic cough and is evident high resolution CT scanning. There remain significant knowledge gaps in our understanding of the epidemiology, pathophysiology, prognosis and optimal treatments in bronchiectasis. This article reviews current concepts in bronchiectasis and focusses on the complex aspects of chronic cough in this setting. Cough is important in bronchiectasis as it is one of the most common presenting symptoms, it affects a patients' quality of life and in conjunction with cough hypersensitivity and airway hyper responsiveness may limit the successful uptake of treatment modalities such as inhaled antibiotics and/or inhaled mucoactive therapies. Effective coughing often assisted by physiotherapy is a cornerstone of bronchial toileting in bronchiectasis. Some patients however have ongoing non-productive cough symptoms suggesting a cough sensitisation syndrome. Post nasal drip and gastro-oesophageal reflux may complicate bronchiectasis and further lead to intractable cough syndromes. There may be multiple cough syndromes within an individual at interplay and careful assessment and multidisciplinary working is needed to optimize symptom control. This article also highlights the many unknowns in chronic cough in bronchiectasis.
