Usefulness of Pyuria to Diagnose UTI in Children

Research about the human microbiome and the therapeutic effect of probiotics is changing fast. It can be difficult to know how to counsel our patients about this important topic. The following table is a summary of some of the recent Integrative Medicine Alert articles as well as some additional recent intriguing and/or seminal works that, I would argue, should be at your fingertips when the topic comes up with your patients. Consider this a "Part 1." Part 2 will add some of the intriguing results surrounding the prevention and treatment of bacterial vaginosis and candidiasis. Table 1 provides a summary of recent research, with diagnoses (and positive or negative effect), type of study, dosing, species (strains) used, and references, including when the topic was covered in Integrative Medicine Alert.
