Insect Bite Guide
Researchers at Johns Hopkins Children’s Center in Baltimore MD have developed a new quick tool to sort out insect bites in children, which can often be misdiagnosed. This tool is called SCRATCH, an acronym for:

Symmetry – eruptions are usually symmetrical and appear on exposed parts of the body
Clusters – lesions caused by bedbugs or fleas appear as linear or triangular clusters
Rover not required – i.e. the presence of pets is not necessary because the bite might occur away from home
Age specific – most prevalent in children between 2–10 years of age
Target/ Time – target shaped lesions are typical of insect-bite hypersensitivity; time indicates the chronic or recurrent nature of eruptions, i.e., many may have delayed reactions)
Confusion – parents often express confusion and disbelief at the suggestion that there might be fleas or bedbugs in their homes
Household –unlike conditions that have similar symptoms (e.g., scabies or eczema), insect-bite rashes often appear in a single member of a family.
It is a guide to the symptoms and features that help pediatricians and others to recognize the source of the rash.

Lice Treatment
A unique pediculicide rinse called Resultz™ (Atlanta Pharma) is now available in pharmacies across Canada in time for the new school year. This product contains 50% isopropyl myristate and 50% ST-cyclomethicone, and, in a Canadian-led study, was shown to be 96% effective in treating head lice.* It does not contain pesticides and resistance is unlikely to develop because of its unique mode of action, i.e., dissolving the wax that covers the exoskeleton of the lice causing dehydration and death.
