Pneumothorax
A pneumothorax is defined as a collection of air between the lung and the chest wall. It can occur spontaneously without lung disease (primary spontaneous pneumothorax) or with underlying lung disease (secondary spontaneous pneumothorax). Trauma, iatrogenic complications of medical procedures and catamenial pneumothorax are other recognized causes. Breathlessness and chest pain are common symptoms. Chest X-ray is the most important investigation to detect and monitor a pneumothorax. Computed tomography of the chest has been widely used as it provides information about the underlying cause and helps to guide intervention. (Source: Medicine)

Lung cancer: investigation and staging
The aim of achieving an accurate diagnosis and staging of lung cancer is to ensure that patients can be offered the most appropriate treatment. Investigations should yield the required level of diagnostic and staging information with the least risk and discomfort for the patient. It is vital that this is in line with the patient's wishes and appropriate to their fitness as well as the potential treatment. Contrast-enhanced computed tomography (CT) of the lower neck, chest, liver and adrenals should be available for most patients at the first clinical assessment. (Source: Medicine)

Pulmonary vascular disease: pulmonary thromboembolism and pulmonary hypertension
The alveolar –capillary barrier, comprising capillary endothelium, extracellular matrix and alveolar epithelium, is a thin membrane that provides a large surface area for diffusive gas exchange. In human health, the pulmonary circulation is completely separate from the systemic circulation, which allows the ma intenance of a high-flow, low-pressure circuit to ensure optimal gas exchange even with increasing physiological demands. Increases in pressure within this circulation either acutely, for example secondary to pulmonary embolism, or over time secondary to vascular remodelling, can detrimentally affec t ventilatory e...

Connective tissue diseases and the lung
Connective tissue diseases (CTDs) include a spectrum of multisystem disorders. Interstitial lung disease (ILD) is an important cause of considerable morbidity and mortality in CTD patients. Although the various CTDs associated with ILD are often considered together because of their shared autoimmune nature, there are substantial differences in clinical presentations and ILD manifestations that are important to consider with regard to management. Here, we summarize each of these major CTD subtypes, highlight how CTD can lead to respiratory manifestations ranging from mild to life-threatening ILD, and discuss the rationale f...

Management of COVID-19 infection
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for coronavirus disease (COVID-19), is estimated to have infected over two-thirds of the world's population and resulted in>6.8 million deaths (as of March 2023). Although multisystem manifestations can occur, COVID-19 is predominantly a respiratory pathogen, and pneumonia is the major cause of morbidity and mortality in hospitalized patients. Management remains largely supportive although, since the start of the pandemic, thousands of research studies, including platform trials RECOVERY and REMAP-CAP, have led to more tailored treatments t...

Opportunistic bacterial, viral and fungal infections of the lung
Respiratory opportunistic infections are a major cause of morbidity and mortality in severely immunocompromised patients, such as those treated with biological therapies, chemotherapy and solid organ or stem cell transplants, and those with haematological malignancy, aplastic anaemia or HIV infection. The type and degree of immune defect dictates the profile of potential opportunistic pathogens; T-cell-mediated defects increase the risk of viral (cytomegalovirus, respiratory viruses) and Pneumocystis jirovecii infections, whereas neutrophil defects are associated with bacterial pneumonia and invasive aspergillosis.

Obstructive sleep apnoea
occurs during sleep when there is repeated pharyngeal collapse that obstructs the airway and causes repeated awakenings from sleep. Sufferers complain of unrefreshing sleep and daytime somnolence. Bed partners usually report snoring with apnoeic attacks. Problems with tasks requiring concentration, such as driving, are common. In severe obstructive sleep apnoea the rate of road traffic accidents secondary to sleepiness is increased. A sleep study incorporating respiratory assessment is required to confirm the diagnosis and severity before the decision is made to initiate continuous positive airway pressure treatment.

Pleural infection
in adults remains a challenging condition to treat with poor outcomes that have persisted over several decades. Research efforts in recent years have significantly advanced our understanding of the aetiopathogenesis and the underlying biology of the infected pleural space. Geographical location and infection setting provide an insight of causative microorganism. Poor pleural fluid culture yields frequently necessitate prolonged courses of broad-spectrum antibiotics. With increased research and accessibility to molecular-based techniques, yields are expected to improve. (Source: Medicine)

Management of acute respiratory failure
Acute respiratory failure is the most common indication for admission to critical care. Appropriate management requires the early recognition and identification of precipitating factors, understanding of the pathophysiology and a systematic approach to assessing disease severity. Finally, if necessary, respiratory support can be non-invasive or invasive mechanical ventilation, and adjunctive therapies, including the timely use of extracorporeal respiratory support.

Clinical tuberculosis
In 1993 the World Health Organization declared tuberculosis (TB) a global public health emergency, and yet 26 years later it remains a significant public health issue globally and nationally within the UK. Although the overall incidence and mortality have improved, there remains considerable work needed to tackle both an underserved population who present unique and complex challenges, and the continuing threat from drug resistance. Within the UK and worldwide, numerous stakeholders have established networks, guidance and frameworks to facilitate a more targeted and standardized approach to detection, diagnosis and managem...

Bronchiectasis
is a heterogenous disease characterized by irreversible airway dilation and damage secondary to chronic inflammation and infection. It is an increasingly prevalent condition with many potential aetiologies. Diagnosis is contingent upon a relevant clinical history in conjunction with specific radiological features. The clinical management of bronchiectasis involves airway clearance, mucoactive agents, anti-inflammatory drugs and antibiotics as either as prophylaxis or treatment for acute respiratory infection.
