Acetaminophen does not aggravate young children’s asthma
Your toddler is screaming in pain. Her forehead is burning. You rush to your local drugstore. What do you get — Tylenol or Motrin? And by the way, she also has asthma. Recently, many parents have been under the impression that acetaminophen (Tylenol, etc.) may do more harm than good in young children with asthma. ...

Can asthma be nipped in the bud?
Worldwide, asthma affects an estimated 300 million people, and is expected to surpass 400 million by 2025, according to the World Health Organization. About 1 in 10 U.S. children have asthma, and research shows that the vast majority of them also have allergy. Could that provide a clue to its prevention? Starting at 2 to ...

A first for CRISPR: Cutting genes in blood stem cells
CRISPR — a gene editing technology that lets researchers make precise mutations, deletions and even replacements in genomic DNA — is all the rage among genomic researchers right now. First discovered as a kind of genomic immune memory in bacteria, labs around the world are trying to leverage the technology for diseases ranging from malaria ...

Beyond appearances: Molecular genetics revises brain tumor classification and care
Pomeroy Scott Pomeroy, MD, PhD, is Neurologist-in-Chief at Boston Children’s Hospital. He practices in the Brain Tumor Center and is a member of the F.M. Kirby Neurobiology Center. For almost a century, brain tumors have been diagnosed based on their appearance under a microscope and classified by their resemblance to the brain cells from which ...

Double stem cell transplant and other tools are helping children survive neuroblastoma
When Emily Coughlin complained of a sore knee in May 2009, doctors initially suspected Lyme disease. After antibiotics failed to relieve the pain, Emily was diagnosed with neuroblastoma, a cancer that begins in nerve cells outside the brain, just shy of her fourth birthday. Though neuroblastomia is rare — about 700 new cases occur annually in the ... Read More about Double stem cell transplant and other tools are helping children survive neuroblastoma
DIY pain relief with light-activated local nerve blocks
You’ve just had a root canal or knee surgery — both situations that will likely require some sort of local pain medication. But instead of taking a systemic narcotic with all its side effects, what if you could medicate only the part of your body that hurts, only when needed and only as much as ...

Forty years waiting for a cure: ALD gene therapy trial shows early promise
A small piece of notepaper, folded twice, sits tucked in a slot of the secretary desk in the living room. Every so often, I pull it out, read it, then reread. Addressed to my mom, the paper has a question and two boxes, one “yes” and one “no,” written with the careful precision of a ...

20-week treatment makes life safer for kids with peanut allergy
A study last week in The New England Journal of Medicine suggests that exposing infants to peanuts can provide lasting protection against peanut allergy. But what about peanut-allergic children right now? They and their parents live a life of precautions — from pre-screening birthday party menus to segregation at the school lunch table — to ...

Targeting synapse loss in Alzheimer’s to preserve cognition — before plaques appear
Currently, there are five FDA-approved drugs for Alzheimer’s disease, but these only boost cognition temporarily and don’t address the root causes of Alzheimer’s dementia. Many newer drugs in the pipeline seek to eliminate amyloid plaque deposits or reduce inflammation in the brain, but by the time this pathology is detectable, it’s unlikely medications can do much to slow ...

Science seen: A “wheel of death” for bacteria
The innate immune system acts like a border patrol for the body, picking up bacteria and other invading pathogens using molecular sensors. One key player is the inflammasome, a multi-protein complex depicted here through cryo-electron microscopy (cryo-EM). Using structural biology tools like cryo-EM and X-ray crystallography, the Wu lab in Boston Children’s Hospital’s Program in Cellular and Molecular ...
