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→

Childhood Immunizations In A Nutshell: Links

I’ve noticed that there are a lot of blog posts on the internet with outdated information about childhood immunizations. Even the links on a whole lot of physicians web pages fail or point to outdated material.

It’s really not surprising due to the many new ‘official recommendations’ published recently following the frequent recurrences of diseases we thought we had eradicated. Un-immunized children are making new epidemics Read more→

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!

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.
