ADHD :: Friendship Clinic for ADHD children

About half of all children with Attention Deficit/Hyperactivity Disorder have difficulty making friends. A new clinical study is helping children with ADHD become better at making friends.

Stem Cell :: Aggressive stem cells might improve transplant outcome

Investigators at St. Jude Children’s Research Hospital have demonstrated in mice a way that might reduce the time it takes for a bone marrow transplant to rebuild a child’s immune system, and so reduce the risk of potentially fatal virus infections that can occur during this time.

Allergy :: All itches not created equal – Different parts of brain activated depending on cause

Different reactions in the brain to two common allergy triggers — allergens (pollen and dust) and histamine (allergy cells within the body caused by foods, drugs or infection) — may shed some light on the itch-scratch cycle. Allergen-induced itch intensity ratings were higher compared to histamine and perception of itch and changes in blood flow were significantly greater when allergen induced. Itch intensity and changes in blood flow were perceived to exist for significantly longer periods.

Physiology :: Brain wave changes in adolescence signal reorganization of the brain

Brain wave changes in adolescence are related to age, but not sexual maturation, occur earlier in girls than boys and may be associated with one of the brain’s major reorganization projects: synaptic pruning, a new study finds. During adolescence, the brain reorganizes and eliminates many synaptic connections, making the brain’s information processing more efficient and powerful while consuming less energy.

Infectious Disease :: GreeneChip – New diagnostic tool identifies multiple pathogens

Researchers in the Greene Infectious Disease Laboratory at Columbia University’s Mailman School of Public Health and their colleagues in the WHO Global Laboratory Network have developed a new tool for pathogen surveillance and discovery — the GreeneChip System. The GreeneChip is the first tool to provide comprehensive, differential diagnosis of infectious diseases, including those caused by viruses, bacteria, fungi or parasites.
