The baby disposable diapers were investigated as a sampling material for urine collection and validated for the evaluation of the exposure of children to xenobiotics. Phthalate metabolites detected in urine samples were chosen as proof-of-concept analytes. For the determination of phthalate metabolites in children's urine samples, high performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS) was used. Two sampling approaches were compared, namely sterile containers and baby disposable diapers. Thirty urine samples from infants and toddlers were analyzed by both methods in parallel and the results were compared. It was found that for diaper sampling, lower concentrations of the metabolites were observed, however, the general distribution for particular metabolites remains the same for both methods. For most of the metabolites high determination coefficients were obtained, namely 0.9929 for MEHHP, 0.9836 for MMP, 0.9796 for MECPP, and 0.9784 for 2-cx-MMHP. For MEOHP the determination correlation coefficient was 0.9154, while for MBP was - 0.7771 and MEHP was - 0.5228. In general, for diaper sampling an underestimation for 2-cx-MMHP and MEOHP was observed, while for MMP diaper-based approach provides overestimation. However, the proposed procedure confirms the possibility of using baby disposable diapers as a material for the collection of urine samples for biomonitoring purposes and fast screening of phthalates exposure.

Purpose: The purpose of this study was to examine characteristics of diaper dermatitis (DD) in critically ill patients aged 0 to 24 months following surgery for congenital heart disease (CHD), the effects of a diaper dermatitis care bundle (DDCB), and factors associated with the development of DD in this population.
Design: Nonrandomized comparison cohort study with a historical comparison group.
Subjects And Setting: Convenience sampling was used to identify children aged 0 to 24 months undergoing CHD and cared for in a pediatric intensive care unit in central Taiwan (Taichung).

Background: Since children have strong desire for exploration and poor safety awareness, foreign body impaction in the digestive tract is one of the most common critical conditions in children. Due to the popularity of electronic products, button battery ingestion by mistake is also increasing in children. Button battery impaction in the esophagus can cause serious complications such as esophageal cauterization and perforation in a short time.

In developing countries, there is currently no established waste management plan that includes resource recovery from used disposable diapers (DDs) apart from incineration and landfilling. In low-income areas with limited storage space, the complex composition and odour of used DDs make it impossible to manage properly if not supported by effective waste management systems. In the absence of effective waste management, DDs are dumped in open spaces, burned or buried.
