Parenting About Sex, Pressure and Promiscuity

“The Talk” isn’t over when your son or daughter says their final “good night” and walks out the door where you’ve been sitting in private discussing the… ahem… “birds and bees” stuff — not, by a long shot!

Puberty: Psychological Stages

I’m sure that Dr. James Tanner didn’t have any idea what would come of it when he took the post that was being offered him by the British Government to continue the Harpenden Orphanage research study in 1948.

Body Odor

Puberty changes everything for a child and body odors are one of them. A day’s activity for a 6 year old still may enable them to skip a night in the tub now and then; an adolescent… not so much.

Hormonal changes alter the content of perspiration in addition to making it more copious – a breeding ground for the bacteria causing odors. Simple things like bathing every night and wearing only cotton underwear as opposed to silk or synthetics may be all that’s needed for them to skip taunts by their “friends.”

Puberty: Tanner Stages – Boys

Boys and puberty – what a topic. We’re told that only two people in the history of planet earth got to skip puberty, so it’s obviously a phenomenon which has been afflicting earth children since … forever.

We’re still trying to figure it out, but the task was made much easier around 1948 when Dr. James M. Tanner, a British pediatric endocrinologist trained in the U.S., was asked to Read more→

Puberty: Tanner Stages – Girls

The original study of childhood growth and maturity done by Dr. Tanner at the Harpenden orphanage in England during WWII has been replicated and verified many times since then.

Puberty: Tanner Stages and Growth

Pretty much the second question you field from a parent during your pediatric clerkship in medical school (right after “what’s this yukky looking rash”) is: “Do you think (insert name here) is growing well enough?” or, some equivalent question.

Puberty Series: Intro/Index

It’s hard to believe, but less than eighty years ago humanity didn’t even have a clue about nutrition let alone what constituted adequate nutrition for a child, let alone a child in puberty!

During the war, there were developing so many refugee children that needed to be cared for by institutions that Great Britan decided to undertake a simple study about what “growth” looked like in children. Nothing was known about that of substance either.

Dr. James Mourilyan Tanner was asked to take over a nutrition study of institutionalized children with the intent of seeing to it that the children still grew well—whatever “well” looked like. He agreed to do it, used the scientific method, devised what is now still the definitive study on growth and puberty (the Tanner Scale) and the rest is history.

This series of posts is all about that. What it is, how it came to be, how it’s used and what we know about the study of puberty.

  • Video: Puberty Time Lapse – 5 Jul 2017
    A child's growth and development always interests a pediatrician. I ran across an effort by a parent to document his child's trip into adulthood with something more than the obligatory photo in a bathtub or school photos. It's an interesting journey into maturity which they will probably both watch many times and a valuable way to document what it took to get where they are now. No wonder teens eat so much and need so much sleep.

Measles: The Real Evidence

This year (2015) the U.S. has suffered a huge increase in Measles. An increase unlike any other in recent years! The blame for much of it has been directly placed at the feet of California residents who exercised a “personal belief” exemption in the state’s childhood immunization requirements.

Internet Vaccination Advice Nearly Killed Their Son

I ran across a poignant article while researching the difficult topic of how parents should use the internet to gain medical information – truly, it sounds simple BUT IT’S NOT.

There is a mind-blowing amount of information exposed by a search on Google for about any medical condition! Unfortunately, there is also an incredible amount of crap exposed in that same search!

Why We Need a “Good Night’s Sleep”

Neuroscientist Jeff Iliff’s sleep research follows two main paths: The first is the exploration of how the brain’s support cells, called glia, contribute to maintaining the proper environment for neuronal function and how their failure in conditions like vascular dementia, stroke, and traumatic brain injury leads to neurodegeneration.

The second seeks to define the basic cellular mechanisms by which brain blood flow is coordinated up and down the vascular tree. A lot to do with sleep.

Now an Assistant Professor of Anesthesiology and Perioperative Medicine at Oregon Health & Science University, Jeff was a part of a University of Rochester Medical Center team that discovered a brain cleansing system, which they dubbed the “glymphatic system.”
