S. stercoralis infection has been identified as a donor‐derived infection in cases of solid organ transplant among recipients with no prior risk factor for parasitic exposure. Worldwide and regional reports from the adult kidney transplant population highlight this indirect method of infection and caution about delayed diagnosis, severe complications, and death related to donor‐derived S. stercoralis infection. We report a deceased‐donor‐derived S. stercoralis infection in a 12‐year‐old Saudi girl who underwent kidney transplantation. This is the first pediatric case reported outside the United States of America. Although she presented with mild bouts of gastrointestinal symptoms, the need for additional immune suppression put her at risk of serious complications. A literature review highlights the importance of awareness about S. stercoralis infections and complications in kidney transplant recipients, pretransplant screening of donors based on risk assessment, and the challenges with treatment availability and duration in this vulnerable population.

Isoniazid (INH) is a first-line tuberculosis (TB) drug and is currently recommended as part of active and latent TB treatment in all ages. INH adverse reactions range from mild hepatitis to severe neurological symptoms and psychosis. Since its introduction in the 1950s, many case reports have explored INH-induced psychosis. We describe a 12-year-old girl with acute onset hallucinations and delusions as a rare complication of INH and review previous case reports and identified risk factors. Pediatricians need to be aware of this less common side effect as they work through a differential of acute psychosis in children.
