Subcutaneous emphysema (SE) and pneumomediastinum are commonly associated with critically ill patients with blunt or penetrating trauma, in particular lower rib fractures. It however rarely needs urgent intervention, and routine use of chest tube tracheostomy or mediastinal drains is not recommended as the patients do not go on to develop a respiratory compromise. Our case is novel as it describes a case of subcutaneous emphysema with acute upper airway compromise and respiratory distress requiring urgent bilateral wide bore subcutaneous drains and thoracic drain insertion. The patient required a prolonged recovery period. This case serves to illustrate the technical difficulty in establishing a cause of subcutaneous emphysema, the limitations of standard imaging in identifying a pneumothorax in subcutaneous emphysema, and the value of prompt insertion of bilateral subcutaneous wide bore drains to buy precious time for definitive imaging and management.

Review
Patients with pertussis can have a variety of complications, including pneumonia and subconjunctival hemorrhage. Severe complications, such as pulmonary hypertension and encephalopathy, can be life-threatening. Younger children with pertussis may lack the characteristic clinical manifestations of pertussis, and therefore, a deeper understanding of the complications of pertussis may help to improve the diagnosis, treatment, and prognosis of pertussis. However, there is still no standard for the diagnosis and treatment of pertussis complications, and there are great differences in diagnostic name, basis, and data used in different reports. This article reviews the complications of pertussis which have been reported so far, such as pulmonary complications (pneumonia, pulmonary hypertension, pneumothorax, and mediastinal or subcutaneous emphysema), fractures, hernias, circulatory system complications, nervous system complications (convulsion, encephalopathy, hemorrhage, and hematoma), urinary system complications, and secondary infections, so as to provide a reference for the clinical diagnosis and treatment of pertussis complications, scientific research on pertussis complications, and the promotion of standardized diagnosis and treatment of pertussis complications.

In the context of mediastinal emphysema/pneumomediastinum, the main aetiologies are associated with oesophageal perforation, lung pathology or post head and neck surgery related. The main way to differentiate the pathologies would be through Computed Tomographic Imaging of the Thorax and abdomen with oral and intravenous contrast in the context of triple phase imaging. The causes of pneumomediastinum should be differentiated between traumatic and non-traumatic. Oesophageal perforation (Boerhaave syndrome) is associated with Mackler's triad in upto 50% of patients (severe retrosternal chest pain, pneumomediastinum, mediastinitis). Whereas in cases of lung pathology this can be associated with pneumothorax and pleural effusion.

Review
Tracheobronchial injuries (TBI) are a heterogenous group of sometimes life-threatening traumas with different management approaches. Symptoms are mediastinal and subcutaneous emphysema, bloody secretions from the airway or haemoptysis in alert patients, and high air leakage along the cuff or increased ventilatory resistance may be signs for TBI in intubated patients. The necessity of immediate clinical evaluation, CT-scan and bronchoscopic evaluation are essential for prompt diagnosis and classification as well as experienced air way management and treatment, these patients are best managed from interdisciplinary teams including thoracic surgeons. While iatrogenic tracheal membrane laceration from intubation can be treated by lesion bridging with ventilation tube, stent application, open operative repair or endoluminal repair, intraoperative accidental cuts should be repaired by direct suture or with vital tissue coverage in case of local ischemia. The management of blunt or penetrating injury is sequential and needs immediate establishment and maintenance of a secure patent airway to provide adequate oxygenation. The next step is the treatment of life-threatening collateral injuries like major hemorrhage, cranial trauma or major organ damage arranged in the trauma team. The treatment of penetrating injuries to the airway need operative exploration in almost every case with minimal local dissection and debridement followed by direct repair. Muscle flap coverage is useful in case of combined esophageal injury. Damage of the tracheobronchial tree after blunt trauma must be repaired by direct suture or local tissue sparing resection and anastomosis. These lesions can be missed in the initial phase and may become prominent with scar tissue formation, stenosis and atelectasis in the later phases.

Review
Recent advances in imaging analysis have enabled evaluation of ventilation and perfusion in specific regions by chest computed tomography (CT) and magnetic resonance imaging (MRI), in addition to modalities including dynamic chest radiography, scintigraphy, positron emission tomography (PET), ultrasound, and electrical impedance tomography (EIT). In this review, an overview of current functional imaging techniques is provided for each modality. Advances in chest CT have allowed for the analysis of local volume changes and small airway disease in addition to emphysema, using the Jacobian determinant and parametric response mapping with inspiratory and expiratory images. Airway analysis can reveal characteristics of airway lesions in chronic obstructive pulmonary disease (COPD) and bronchial asthma, and the contribution of dysanapsis to obstructive diseases. Chest CT is also employed to measure pulmonary blood vessels, interstitial lung abnormalities, and mediastinal and chest wall components including skeletal muscle and bone. Dynamic CT can visualize lung deformation in respective portions. Pulmonary MRI has been developed for the estimation of lung ventilation and perfusion, mainly using hyperpolarized Xe. Oxygen-enhanced and proton-based MRI, without a polarizer, has potential clinical applications. Dynamic chest radiography is gaining traction in Japan for ventilation and perfusion analysis. Single photon emission CT can be used to assess ventilation-perfusion (V˙/Q˙) mismatch in pulmonary vascular diseases and COPD. PET/CT V˙/Q˙ imaging has also been demonstrated using "Galligas". Both ultrasound and EIT can detect pulmonary edema caused by acute respiratory distress syndrome. Familiarity with these functional imaging techniques will enable clinicians to utilize these systems in clinical practice.
