  1. Dwarfism Kody Prince Karishma Mendes

  2. What is Dwarfism? • Dwarfism is characterized by short stature. Technically, that means an adult height of 4 feet 10 inches or under, according to the advocacy group Little People of America. http://www.youtube.com/watch?v=iC5B3zU0Iv0 http://www.youtube.com/watch?v=WoYeU6onK3g

  3. Causes • Dwarfism can be caused by any one of more than 200 conditions, most of which are genetic. The most common type, accounting for 70% of all cases of short stature, is called Achondroplasia.

  4. Causes • Dwarfism causes mostly occurs in families where both parents are an average height. In fact, 4 out of 5 of children with Achondroplasia are born to average-size parents.

  5. Signs and Symptoms • Dwarfism symptoms other than short stature vary considerably across the spectrum of disorders. In general, the disorders are divided into two broad categories: • Disproportionate dwarfism. • Proportionate dwarfism.

  6. Signs and Symptoms There are some symptoms like: • Poor growth • Failure to thrive • Short stature • Short bones • Short arms • Short legs

  7. Diagnostic Test Treatments • Measurements (when young generally check up) • History (look at the past medical history in your family) • MRI (scan for abnormal formalities on the skull and other parts)

  8. Complications Some complications: Small legs Small legs Large head compared to the body Smaller organs

  9. Disproportionate Dwarfism • Disproportionate Dwarfism is one category of dwarfism meaning in a way it as the same signs and symptoms.

  10. Disproportionate Dwarfism • Usually a person has an average-size trunk and very short limbs, but some people may have a very short trunk and shortened limbs. Some characteristic of this disorders is the head being disproportionately large compared to the body.

  11. Causes • The most common cause of dwarfism is a disorder called achondroplasia, which causes disproportionately short stature. the other rare disorder that causes disproportionate dwarfism is called spondyloepiphyseal dysplasia congenita.

  12. Signs and Symptoms • An average-size trunk • Short arms and legs, with particularly short upper arms and upper legs • Short fingers, often with a wide separation between the middle and ring fingers • Limited mobility at the elbows

  13. Proportionate Dwarfism • Proportionate dwarfism results from medical conditions present at birth or appearing in early childhood that limit overall growth and development.

  14. Signs and Symptoms • Therefore, the head, trunk and limbs are all small, but they are proportionate to each other.

  15. Cause • Therefore this disorders affects overall growth, many of them result in poor development of one or more body systems.

  16. Achondroplasia • A person with Achondroplasia and with two average-size parents received one mutated copy of the gene associated with the disorder and one normal copy of the gene.

  17. Causes • A person with the disorder may pass along either a mutated or normal copy to his or her own children.

  18. Turner Syndrome • Turner syndrome occurs because of a random deletion or severe alteration of an X chromosome either in the sperm or egg. • The X chromosome is one of two chromosomes that determine the sex of a person. http://www.youtube.com/watch?v=ldjb-FR-PKo

  19. Causes • A girl with Turner syndrome has only one fully functioning copy of the female sex chromosome rather than two.

  20. Signs Symptoms • Absent or incomplete development at puberty, including sparse pubic hair and small breasts • Broad, flat chest shaped like a shield • Drooping eyelids • Dry eyes • No periods (absent menstruation) • Short height • Vaginal dryness, can lead to painful intercourse
