Acute Airway Compromise Due to Spontaneous Pneumomediastinum in COVID-19 Infection and Subsequent Rapid Formation of Pulmonary Subpleural Bullae: A Case Report.

Spontaneous pneumomediastinum (SPM), an increasingly documented complication of COVID-19 infection, usually presents with retrosternal chest pain and dyspnea but can present atypically. In this case, an exceptionally rare presentation could have led to inappropriate management and a poor outcome. Here, a previously healthy 41-year-old Afro-Caribbean male non-smoker presents with acute airway compromise due to SPM.

Posterior Reversible Encephalopathy Syndrome and Acute Post-Streptococcal Glomerulonephritis Mimicking Breakthrough Seizures.

We report the case of a 14-year-old boy with a past history of primary generalized seizures, who had been seizure-free for 2 years on sodium valproate and presented with generalized tonic clonic seizures suggestive of breakthrough seizures. Examination revealed hypertension, impetiginous lesions of the lower limbs, microscopic hematuria, elevated anti-streptolysin O titre and low complement levels consistent with acute post-streptococcal glomerulonephritis. Cranial magnetic resonance imaging (MRI) demonstrated changes consistent with posterior reversible encephalopathy syndrome.
