In this issue of the Journal of Korean Medical Science, an article reports on the clinical aspects of childhood diarrhea in North Korea (Democratic People’s Republic of Korea).1 The authors analyzed articles from major North Korean medical journals published during the years preceding the coronavirus disease 2019 pandemic. These journal articles were written in Korean and were typically just one or two pages long and often omitted critical scientific information on study subjects and research methods. These 43 articles were composed mainly of case-control studies (33 articles) and observational studies (9 articles). The major causes of diarrheal diseases were infectious (viral—including rotaviral, bacterial, and parasitic) and indigestion or malabsorption. Treatment modalities were various, i.e., rehydration solutions, antibiotics, probiotics, and vitamin supplements. These were similar to those in other developing countries, except for the trials involving North Korean traditional medicine (Koryo medicine) using extracts from herbs and animals, minerals, and/or manual therapies. However, as the authors noted with regret, accurate prevalence rates could not be elucidated from the analysis of North Korean journals.
