An elderly man presenting with shortness of breath and hypoxaemia was admitted with acute hypoxic respiratory failure secondary to COVID-19 pneumonia. Due to worsening hypoxaemia, he was transferred to the intensive care unit and required mechanical ventilation. Propofol was infused at 1.5–4 mg/kg/hour. Within 48 hours of initiation, we noticed worsening metabolic acidosis, acute kidney injury, hyperkalaemia, hyperphosphataemia, hypertriglyceridaemia, elevated creatine kinase and elevated myoglobin levels. Suspecting propofol-related infusion syndrome (PRIS), we discontinued his propofol infusion immediately and initiated supportive measures. In 48 hours, there was a significant improvement in metabolic acidosis, hypertriglyceridaemia, rhabdomyolysis and renal function. The propofol infusion rate and cumulative propofol dosage (under 140 mg/kg) were well below levels associated with PRIS. COVID-19’s pathogenesis, still under investigation, may have contributed to this presentation. It is imperative for clinicians to maintain a high degree of suspicion once propofol is initiated, regardless of the cumulative dose or rate of infusion.
Bannayan-Riley-Ruvalcaba syndrome (BRRS) is a rare genetic disorder caused by germline mutations in the phosphatase and tensin homolog (PTEN) gene. Clinical manifestations arise early during childhood and include multiple lipomas, hamartomatous intestinal polyps, macrocephaly, developmental delay, and autism spectrum disorder among others. The case describes a 24-year-old female with a recent diagnosis of BRRS who presented for evaluation of burning epigastric pain for the previous six months. The esophagogastroduodenoscopy (EGD) and colonoscopy revealed an erosive gastric mucosa as well as numerous polyps throughout the gastrointestinal tract. Histopathologic examination confirmed gastric Helicobacter pylori infection and different histologic types of polyps.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
