Comparison of Bacillus Calmette-Guérin Maintenance Therapy with Monthly Instillations and the Southwest Oncology Group Protocol in the Treatment of Non-muscle-invasive Bladder Cancer.

Background: Bacillus Calmette-Guérin (BCG) therapy using the Southwest Oncology Group (SWOG) maintenance protocol is the standard in non-muscle-invasive bladder cancer (NMIBC). Maintenance with monthly instillations is also widely used, but evidence comparing the two maintenance protocols is scarce.

Objective: To compare monthly and SWOG instillation schedules in maintenance BCG therapy.

Cut-off values to evaluate exercise-induced asthma in eucapnic voluntary hyperventilation test for children.

Background And Aim: The eucapnic voluntary hyperventilation (EVH) testing is a diagnostic tool for diagnostics of exercise-induced bronchoconstriction; while the testing has become more common among children, data on the test's feasibility among children remain limited. Our aim was to investigate EVH testing feasibility among children, diagnostic testing cut-off values, and which factors affect testing outcomes.

Methods: We recruited 134 patients aged 10-16 years with a history of exercise-induced dyspnoea and 100 healthy control children to undergo 6-min EVH testing.

Human bocaviruses and paediatric infections.

Human bocavirus 1 (HBoV1), belonging to the Parvoviridae family, was discovered in 2005, in nasopharyngeal samples from children with respiratory tract infections. Three additional bocaviruses, HBoV2-4, were discovered in 2009-10. These viruses have mainly been found in faecal samples and their role in human diseases is still uncertain.
