Splenic abscess secondary to COVID-19 acute infection: A case report and literature review.

Rationale: Splenic abscess is relatively rare in clinical practice as an invasive disease. However, during the continuous prevalence of coronavirus disease 2019 (COVID-19), the incidence rate of splenic abscess showed an upward trend. However, because the etiology of splenic abscess is not specific, it is easy to be covered by the respiratory symptoms of COVID-19, resulting in omission or delay in diagnosis.

Adrenaline intravenous therapy persistence grade I severe allergic reaction: A case report and literature review.

Adrenaline remains the preferred medication for severe allergic reactions, and intramuscular injection of adrenaline can also be considered for patients with grade I reactions that are difficult to alleviate gastrointestinal symptoms. It is worth further discussing whether it is possible to break the conventional intramuscular injection recommended by the guidelines when the effect of intramuscular injection is not ideal for persistent grade I severe allergic reactions.
