    Precocious Puberty Precocious Puberty Presentation Transcript

    • Precocious Puberty
    • What is Precocious Puberty?
      Section 1
    • Definition
      The process of changing from a child into an adult capable of reproduction
      Occurs between ages 10-14 for girls, and ages 12-16 for boys
      Precocious Puberty
      Puberty that begins before age 8 for girls and before age 9 for boys
    • Causes
      For the majority of children, no underlying medical problem and no identifiable reason for the early puberty.
      2 Types of Precocious Puberty
    • Central
      Most common form of precocious puberty
      Puberty process starts too soon, but the pattern and timing of the steps in the process are normal
    • Rare Causes of Central Precocious Puberty
      Tumor in brain or spinal cord
      Brain defect present at birth
      Injury to brain or spinal cord
      McCune-Albright syndrome
      Genetic disease, affects bones and skin color, causes hormonal problems
      Congenital adrenal hyperplasia
      Group of inherited disorders, causes abnormal hormone production by adrenal glands
      Condition where thyroid doesn’t produce enough hormones
    • Peripheral
      Less common
      Occurs without the hormone in your brain that usually causes puberty to start (Gn-RH)
      Caused by the release of estrogen or testosterone into the body because of problems with the ovaries, testicles, adrenal glands or pituitary gland
    • Other Causes
      Little evidence, but these may be contributing factors to precocious puberty:
      Environmental Factors
      Increase in hormones found in food
      Exposure to household toxins (BPA)
      ~106 lbs is the weight when puberty starts
      Leptin, a hormone involved in puberty, is secreted in fatty tissue (more fatty tissue=more leptin=earlier puberty)
    • Other Causes
      Social Factors
      Girls growing up in stressed families reach puberty earlier
      Girls growing up without fathers
      Media: Some suggest increasingly overt sexuality in popular media may stimulate earlier puberty (but no solid proof yet)
    • How to Measure Puberty
      Doctors utilize Tanner Stages to assess the advancement of puberty.
      There are 5 Tanner Stages for each sex.
      Each stage corresponds to specific changes in secondary sex characteristics.
      Source: Carel & Leger, 2008.
    • Tanner Stages
      Source: Carel & Leger, 2008.
    • Tanner Stages & Sex Differences
      • Bodily changes characteristic of Tanner Stage 2 signal the beginning of puberty for boys and girls.
      • There appears to be more girls than boys who experience precocious puberty.
      • In a study of Danish children, 0.2% of girls underwent precocious puberty, compared to about 0.05% of boys.
      Source: Carel & Leger, 2008.
    • When to Consult a Doctor
      Age: < 8 years old
      Physical Features:
      - breast growth
       Tanner Stage 3-5
       If at Tanner Stage 2, there
      must be other features
      (e.g. a recent growth spurt).
      Age: < 9.5 years old
      Physical Features:
      - secondary sex characteristics
       Tanner Stage 2 - 5
      Source: Carel & Leger, 2008.
    • Precocious Puberty and Height
      Individuals who experience puberty at a younger age and do not receive treatment for it tend to be shorter in stature as adults, relative to the rest of the adult population.
      These men tend to be 7.9 inches shorter than average.
      These women tend to be 4.7 inches shorter than average.
      Sources: Carel & Leger, 2008; Nield, Cakan, & Kamat 2007.
    • Emotional Responses to Precocious Puberty
      Both boys and girls may develop strong emotional reactions to precocious puberty.
      In particular, studies have shown that many girls feel anxious about the changes that their bodies are undergoing.
      The emotional consequences of precocious puberty warrant as much attention as the physical.

    • How an Individual Can Cope with Precocious Puberty
      Section 2
    • Educate Yourself About the Changes
      Understand the biological aspects
    • Things to Consider
      As the physical appearance of an individual matures, one must realize possible changing social norms and expectations.
    • Realize that there are a variety of body types — big, small, and everything in between.
      Try not to compare yourself with those around you
      Avoid those with negative outlooks; surround yourself with those who care about you
      Talk to someone you trust, they could offer suggestions and make you feel a little less alone
    • Avoid those with negative outlooks; surround yourself with those who care about you.Talk to someone you trust, they could offer suggestions and make you feel a little less alone.
    • Everyone goes through puberty, don't be embarrassed to talk about it with your parents, older siblings, or your friends. You may be surprised to find out that they have many of the same thoughts and questions as you do.
    • Treatment Choices
      Section 3
    • Usually treatment consists of providing gonadotrophin-releasing
      hormone (GnRH) analogues.
      Usually results in a decrease in growth
      Combining growth hormone (GH) to GnRH treatment results in a higher
      final height in girls
      Possible Treatments and Outcomes:
      Source: Tuverno et al., 2001.
    • Rare cases
      Male-Limited precocious Puberty (testotoxicosis)
      Long Term Results:
      Usually treated with cyproterone acetate or ketoconazole
      •    Results in decrease growth velocity
      •    Bone age/chronological age ratio decreased after therapy
      •    Testosterone levels significantly lower in patients who were treated
      with ketoconazole then with cyproterone acetate
          Both treatments had similar outcomes without vital side-effects
      •    Both treatments showed limited efficacy in reaching normal adult height
      Source: Almeida et al., 2008.
    • How Parents Can Help
      Section 4
    • Talk to Them:
      Give your child a simple, truthful explanation about what's happening.
      Explain that these changes are normal for older kids and teens, but that his or her body has started developing a little too early.
      Keep your child informed about treatment and what can be expected along the way.
      watch for signs that teasing or other difficulties associated with precocious puberty may be affecting your child's emotional development.
    • Warning Signs of Effects on Emotional Development
      poor grades
      problems at school
      loss of interest in daily activities
    • How you cope with the issue can also determine how successfully your child will cope.
    • The goal is to prevent kids from dwelling on sexual development or developing a poor self-image or low self-esteem.
    • Try not to focus your comments on appearance; instead, offer praise for achievements in school or sports and support your child's participation in other activities.
    • The important thing to remember is that kids with precocious puberty can be treated. Doctors can help them preserve their adult height potential as well as limit the emotional and social difficulties they may face from maturing early.
    • Give your child with precocious puberty love and support!
