Measuring Early Childhood Development Among 4-6 Year Olds: The Identification of Psychometrically Robust Items Across Diverse Contexts.

The last 15 years have seen an explosion of measurement tools for assessing the development of young children in low- and middle- income countries. This paper builds on and contributes to that literature by identifying a core set of caregiver-report items and a core set of direct assessment items that measure key developmental domains for children aged 4-6 (48-83 months) and that demonstrate adequate psychometric properties across diverse contexts, the first in this age group to the authors' knowledge. Data were harmonized from previous early childhood measurement efforts in 12 countries that all used the same base measurement tool.

Anaphylactic shock perioperative to patent blue dye.

Patent blue is one of the most used dyes for the identification of sentinel lymph nodes in breast cancer. This report describes a case of an anaphylactic shock reaction to patent blue dye in a patient with cross-reactivity to methylene blue. Therefore, after allergy confirmation, the operation was repeated avoiding blue dye and an alternative labelling technique with 99mTc albumin nanocolloids was used.
