ABSTRACT
There has been a worldwide increase in cases of diabetic ketoacidosis in both adults and children with diabetes during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. This can be multifactorial: delayed care due to reduced medical services, fear of approaching hospitals, or SARS-CoV-2 infection itself. It is well-known that infection is an important trigger for diabetic ketoacidosis in children with type 1 or type 2 diabetes mellitus, but little is known whether SARS-CoV-2 infection can trigger diabetic ketoacidosis and new-onset diabetes mellitus in a child with no previous history of diabetes mellitus. The association of SARS-CoV-2 as a trigger for new-onset diabetes requires further investigation, as the incidence of diabetes is steadily rising in the pediatric population during the pandemic. This case report explores two cases where children present in diabetic ketoacidosis with concurrent SARS-CoV-2 infection and no known history of type 1 diabetes mellitus.
ABSTRACT
Methaemoglobinaemia is a potentially life-threatening condition characterised by hypoxaemia, cyanosis, pallor, fatigue, metabolic acidosis, headache and in severe cases, coma or death. Topical anaesthetics have been reported to cause methaemoglobinaemia. Topical benzocaine was specifically implicated in roughly 66% of anesthetic-induced methaemoglobinaemia cases in a large systematic review in adults. This complication has occurred often in adult patients with pre-existing comorbidities resulting in diminished use in children overall with only few paediatric cases reported worldwide. Additionally, there is growing evidence of a link between sepsis and methaemoglobinaemia due to increased circulating nitrous oxide from infectious pathogen metabolism. In this report, we discuss a case of a 16-year-old young boy, being evaluated for suspected endocarditis, presenting with acute methaemoglobinaemia after use of topical benzocaine spray for transesophageal echocardiogram. This case exemplifies the importance of blood gas with co-oximetry testing in all cases of refractory hypoxemia who have had procedures requiring topical anaesthetics.
