The severity of coronavirus 2019 infection (COVID-19) is determined by the presence of pneumonia, severe acute respiratory distress syndrome (SARS-CoV-2), myocarditis, microvascular thrombosis and/or cytokine storms, all of which involve underlying inflammation. A principal defence against uncontrolled inflammation, and against viral infection in general, is provided by T regulatory lymphocytes (Tregs). Treg levels have been reported to be low in many COVID-19 patients and can be increased by vitamin D supplementation. ⋯ Vitamin D deficiency has been found to occur more frequently in patients with obesity and diabetes. These conditions are reported to carry a higher mortality in COVID-19. If vitamin D does in fact reduce the severity of COVID-19 in regard to pneumonia/ARDS, inflammation, inflammatory cytokines and thrombosis, it is our opinion that supplements would offer a relatively easy option to decrease the impact of the pandemic.

A case is presented highlighting the emerging association of COVID-19 with pneumomediastinum, even in patients who have never received mechanical ventilation or positive airway pressure.

Haemolysis is a rare but serious complication of cytomegalovirus (CMV) infection, described mostly in immunocompromised patients, the pathogenesis of which is yet to be fully elucidated. We describe a case of Coombs-positive haemolytic anaemia in an older Caucasian immunocompetent woman after polytrauma, resulting from suspected reactivation of CMV infection and secondary cold agglutinin disease. Clinicians should consider CMV infection in the differential diagnosis of haemolytic anaemia in immunocompetent older adults who are admitted with significant musculoskeletal trauma. Early treatment with B-cell depletion therapy to halt cold agglutinin production can be life-saving.

The diagnosis of multiple sclerosis (MS) is through clinical assessment and supported by investigations. There is no single accurate and reliable diagnostic test. MS is a disease of young adults with a female predominance. ⋯ The differential diagnosis includes other inflammatory central nervous system disorders. Magnetic resonance imaging of the brain and lumbar puncture are the key investigations. New diagnostic criteria have been developed to allow an earlier diagnosis and thus access to effective disease modifying treatments.

After severe COVID-19 disease, many patients will experience a variety of problems with normal functioning and will require rehabilitation services to overcome these problems. The principles of and evidence on rehabilitation will allow an effective response. ⋯ The large number of COVID-19 patients needing rehabilitation coupled with the backlog remaining from the crisis will challenge existing services. The principles underpinning vital service reconfigurations needed are discussed.
