ReviewArtificial Intelligence in plastic surgery: What is it? Where are we now? What is on the horizon?
An increasing quantity of data is required to guide precision medicine and advance future healthcare practices, but current analytical methods often become overwhelmed. Artificial intelligence (AI) provides a promising solution. Plastic surgery is an innovative surgical specialty expected to implement AI into current and future practices. It is important for all plastic surgeons to understand how AI may affect current and future practice, and to recognise its potential limitations. ⋯ Current machine learning models using convolutional neural networks can evaluate breast mammography and differentiate benign and malignant tumours as accurately as specialist doctors, and motion sensor surgical instruments can collate real-time data to advise intraoperative technical adjustments. Centralised big data portals are expected to collate large datasets to accelerate understanding of disease pathogeneses and best practices. Information obtained using computer vision could guide intraoperative surgical decisions in unprecedented detail and semi-autonomous surgical systems guided by AI algorithms may enable improved surgical outcomes in low- and middle-income countries. Surgeons must collaborate with computer scientists to ensure that AI algorithms inform clinically relevant health objectives and are interpretable. Ethical concerns such as systematic biases causing non-representative conclusions for under-represented patient groups, patient confidentiality and the limitations of AI based on the quality of data input suggests that AI will accompany the plastic surgeon, rather than replace them.

Case ReportsA seven-month-old with chronic intermittent biphasic stridor.
Paediatric stridor can indicate serious pathology and requires prompt evaluation and management. Causes range from laryngomalacia to aerodigestive tract foreign bodies. We report on a chronic presentation of paediatric stridor, discuss the workup, management and lessons learned. ⋯ Foreign bodies in the airway and oesophagus are quite common in children, causing symptoms from the aerodigestive tract. It is uncommon for oesophageal foreign bodies to present with stridor in the absence of digestive tract symptoms. The otolaryngologist should consider this as a diagnosis, particularly in young children with an atypical presentation and symptoms.

Case ReportsExtensive pneumatosis intestinalis and portal venous gas mimicking mesenteric ischaemia in a patient with SARS-CoV-2.
We present the case of a critically ill 47-year-old man diagnosed with SARS-CoV-2 (COVID-19) who developed extensive pneumatosis intestinalis and portal venous gas in conjunction with an acute abdomen during the recovery phase of his acute lung injury. A non-surgical conservative approach was taken as the definitive surgical procedure; a complete small-bowel resection was deemed to be associated with an unacceptably high long-term morbidity. ⋯ Pneumatosis intestinalis from non-ischaemic origins has been described in association with norovirus and cytomegalovirus. To our knowledge, this is the first time that this has been described in COVID-19.
