Sympathy vs. empathy Basic information about Duchenne muscular dystrophy Inheritance Prevalence Symptoms Treatments Understanding Sympathy A feeling or an

expression of pity or sorrow for the distress of another; compassion or commiseration (4) Understanding Empathy Identification with and understanding of another's

situation, feelings, and motives (4) What Is Duchenne Muscular Dystrophy?(1) Genetic Progressive muscle weakness

Defects in muscle proteins Death of muscle tissue Where is This Gene? Duchenne Muscular Dystrophy Inheritance(1) Mother carries the recessive gene and passes it to her child

Trait is usually expressed in males only Punnett Square Link Prevalence of DMD Affects one in 3500 to 5000 newborn males 1/3 of these with

previous family history 2/3 sporadic (1) Symptoms of DMD (1) Delayed developmental milestones

Loss of motor skills Characteristic gait Calf hypertrophy Clumsiness/frequent falls

More Symptoms of (1) DMD Muscle weakness Difficulty climbing stairs or hills Difficulty rising (Gowers sign)

Difficulty walking/running Link to Gower's Sign Treatments for DMD To improve breathing: O 2 therapy

Ventilator Scoliosis surgery Tracheotomy (1) Treatments (cont.) To improve mobility: Physical therapy

Surgery on tight joints Prednisone Non-steroidal medications Wheelchair

(1) The Beginning of Gene Therapy for DMD (2) Advances in Gene Therapy(3) Researches have developed "minigenes," which carry instructions for a slightly smaller version of dystrophin, that can fit

inside a virus Researchers have also created the so-called gutted virus, a virus that has had its own genes removed so that it is carrying only the dystrophin gene Problems with Gene Therapy(3) Muscle tissue is large and relatively impenetrable

Viruses might provoke the immune system and cause the destruction of muscle fibers with the new genes Summary Empathy vs. sympathy

Definition of muscular dystrophy Inheritance Prevalence Symptoms Treatments Making Real Sense of the Senses by Mattie Stepanek Our eyes are for looking at things. But they are also for crying When we are very happy or very sad. Our ears are for listening, But so are our hearts. Our noses are for smelling food, But also the wind and the grass and If we try really hard, butterflies.

Our hands are for feeling, But also for hugging and touching so gently. Our mouths and tongues are for tasting But also for saying words, like "I love you" and "Thank you, God, for all of these things." Mattie's Home Page References: 1.
