Supratherapeutic lithium levels in COVID-19 infection.

Lithium levels are often checked in the inpatient setting when a patient has clear indications of acute kidney injury. Lithium levels can become supratherapeutic in COVID-19 infection even after normalization of creatinine. Lithium levels should be checked routinely in patients with COVID-19 infection in order to avoid supratherapeutic levels.

Prevalence of Anti-tissue Transglutaminase Antibodies and Celiac Disease in Children With Inflammatory Bowel Disease.

Objectives: Celiac disease can occur in children with inflammatory bowel disease (IBD) and poses a diagnostic challenge. We evaluated the presence of anti-tissue transglutaminase (tTG) antibodies and celiac disease among children with IBD.

Methods: In a retrospective chart review, we assessed the prevalence of tTG antibodies and celiac disease and compared with a control group of children with gastrointestinal symptoms without IBD.

Prevalence and Patterns of Marijuana Use in Young Adults With Inflammatory Bowel Disease.

Objectives: Recent studies in adults report symptom relief with marijuana use in patients with inflammatory bowel disease (IBD). We assessed the prevalence, pattern, effects, and adverse effects of marijuana use in young adults with IBD.

Methods: We conducted a prospective questionnaire survey study at a pediatric IBD clinic.

Prevalence and Clinical, Endoscopic, and Pathological Features of Duodenitis in Children.

Objectives: Although gastritis and esophagitis are well studied in children, there is very limited literature on duodenitis in children. We aimed to assess the prevalence, etiology, clinical, endoscopic, and pathological features in a large cohort of unselected children with duodenitis.

Methods: We reviewed the pathology reports of all the upper endoscopies performed at our institution during 5 years to identify children with duodenitis.
