COVID-19 Vaccine Cardiac Complications: A Case Series on Implications of Marijuana in Adolescents With Myopericarditis.

We report on two critically ill pediatric patients, aged 16 and 18 years, presenting with acute myopericarditis at a tertiary-care center in New Jersey, United States. Both patients had their severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations, tested negative for SARS-CoV-2, and shared only significant history of asthma. Clinical presentations were similar to acute onset chest pain that worsened with deep inspiration.

Severe Enteritis as the Sole Manifestation of Novel Coronavirus Disease 2019 (COVID-19) in Adolescent Patients.

Enteritis as the only manifestation of novel coronavirus disease 2019 (COVID-19) in adolescents without features of multisystem inflammatory syndrome in children (MIS-C) or a prior history of inflammatory bowel disease (IBD) has not been described. We report two adolescent patients (a 14-year-old male and a 20-year-old pregnant female) presenting to tertiary-care centers in the United States with severe enteritis as the only manifestation of COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The patients were hospitalized with acute abdominal pain and gastrointestinal (GI) bleeding, with no evidence of MIS-C, and were previously healthy with no history of IBD.

Multisystem Inflammatory Syndrome in Children (MIS-C) Associated with 2019 Novel Coronavirus (SARS-CoV-2) Infection.

We report three critically ill pediatric patients (aged 6-10 years), presenting with features of multisystem inflammatory syndrome in children (MIS-C) from April 4 to May 10, 2020, to a tertiary-care center in New Jersey, United States. All patients tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and were previously healthy.
