Methylene blue is the first-choice treatment of methemoglobinemia, but it is not readily available in most Korean emergency departments because of an import suspension. An 84-year-old woman with dapsone-induced massive methemoglobinemia visited our emergency department for unclear mentality and cyanosis. ⋯ Vitamin C (10 g intravenously) administered 6 hourly successfully treated the dapsone-induced methemoglobinemia and did not adversely affect renal functions. Thus,we recommend that if methylene blue is unavailable, 6 hourly intravenous administrations of 10 g of VC should be considered for dapsone-induced methemoglobinemia.

The aim of this study was to analyze the day-of-the-week variations of acute myocardial infarction (AMI) over a 27-year period. The effects of sex, age, history of AMI, hypertension, fatality, and temporal changes over the 27-year period were also investigated. ⋯ The present study demonstrates that there is a marked incidence peak in AMI on Mondays. This peak is similar for men and women but varies according to age. The Monday peak is not observed in subjects previously admitted for AMI or in fatal cases. The organization of the emergency medical services could take into account the day-of-the-week pattern of AMI to adapt emergency medical service capacity to needs.

There have been mounting safety concerns over increasing prescription rates for proton pump inhibitors (PPIs). Trends in PPI use have not been studied in emergency departments (EDs). We characterize trends in PPI use in US EDs. ⋯ Over the past decade, there have been considerable increases in PPI prescribing in US EDs. This trend occurred despite rising safety concerns, even in populations at higher risk for adverse events such as older adults. More education may be needed to ensure that ED providers are familiar with indications for PPIs.
