Lichenoid cutaneous skin eruption and associated systemic inflammatory response following Pfizer-BioNTech mRNA COVID-19 vaccine administration.

The global effects of coronavirus disease 2019 (COVID-19) have driven unprecedented rapid development and mass deployment of vaccinations against the novel coronavirus. However, the short- and long-term adverse reactions following COVID-19 vaccinations are still under investigation as insufficient time has passed to fully explore these. The Pfizer-BioNTech COVID-19 mRNA vaccine has thus far shown a favourable safety profile in phase I-III studies.

Thunderstorm-related asthma can occur in New Zealand.

Thunderstorm asthma is induced by specific weather conditions causing breakdown and widespread distribution of allergens. Thunderstorm asthma had previously been considered unlikely to occur in New Zealand (NZ), given its local weather patterns. Storm events on 2 December 2017 led to increased asthma presentations at Waikato Hospital in Hamilton.

Co-diagnoses of acute myeloid leukaemia and COVID-19: presentation and management implications.

We report a case of concurrent new diagnoses of confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and acute myeloid leukaemia (AML). We review the existing literature on coronavirus disease 2019 (COVID-19) in the immunocompromised patient and the implications for managing our patient's haematological neoplasm. The implications of severe immunocompromise are unclear in the context of infection with SARS-CoV-2.

Dyspnoea and restrictive lung disease due to mediastinal and pleural lipomatosis in morbid obesity.

Dyspnoea in obese patients can be multifactorial and complex. Mediastinal and pleural lipomatosis can be associated with obesity and is usually considered asymptomatic and benign. We report an obese 39-year-old man who presented with progressive dyspnoea, where in addition to obstructive sleep apnoea and obesity hypoventilation syndrome, was found to have massive mediastinal and pleural lipomatosis causing restrictive lung disease.
