How might Duchenne muscular dystrophy be treated 10 years from now?
19-year-old non- ambulatory male with pneumonia Chief Complaint: 19-year-old non-ambulatory male with pneumonia. History: James Fenlow, a 19-year old male, is immobile and hospitalized for pneumonia. He has a long history of progressive weakening of his muscles. In the first year of his life, James reached many gross motor skill milestones, such as holding his head up, rolling over, sitting, and standing, at normal times. However, he did not walk until age 16 months, and by age two, started to assume a lordotic posture while standing but not while sitting, A Gower's sign was noted by age four, as was a Trendelenberg gait. Over the next several years, he suffered progressive muscle weakness, most notably in the proximal musculature of the arms, pelvis, and legs. By age 9, he required orthotic braces to assist his walking, and by age 11, he was confined to wheelchair ambulation. In his early teen years, James was still able to use eating utensils, write, and type on a keyboard, though these functions have declined over the past year. At 16, he was hospitalized with bronchitis requiring antibiotic treatment, but recovered. Throughout the years, James has had no history of muscle pain or spasm, chest pain, or irregular heartbeat. He was diagnosed with a learning disability in the fourth grade, but has progressed through the grades with tutorial assistance. The only mearann hat he normally
assistance. The only medications that he normally takes are calcium and fluoride supplements. James has a younger sister in good health and a younger brother (age 10) who is confined to a wheelchair with problems similar to James's. No other immediate or distant family members have musculoskeletal difficulties. Physical Examination: On examination, James appeared fatigued and short of breath. Vital signs: (1) heart rate = 104 beats per minute, (2) respiratory rate = 28 breaths per minute, (3) temperature (oral) – 102.4 degrees F, and (4) blood pressure – 138/ 74. Pupils were normal and reactive to light, with ocular movements intact. No dysarthria or facial muscle weakness was noted. Percussion of the thorax suggested pulmonary infiltrates in the lower lung fields bilaterally. Breath sounds were reduced, with significant inspiratory rales heard over both lungs. His cough was very weak, but productive of green sputum. Heart sounds were normal, with no murmur. Bowel sounds were normal. Musculoskeletal exam revealed a scoliotic deformity of the spine when James sat up. Upper chest, shoulder, and thigh muscles were significantly atrophied, but the calf muscles appeared enlarged. Bilateral elbow contractures limited elbow extension to 80 degrees. Bilateral Achilles contractures were also present. Muscle strength was reduced in the biceps and triceps brachii muscles bilaterally (+2 on a scale from 0 to +5, +5 being normal), deltoids (+1). and he was not able to move either thigh into flexion or extension. Muscle stretch reflexes (rated on a scale from 0 to +4, +2 being normal) were as follows: right and breepend treeps brachii (+1).
flexion or extension. Muscle stretch reflexes (rated on a scale from 0 to +4, +2 being normal) were as follows: right and left biceps and triceps brachii (+1), right and left brachioradialis (+1), right and left patellar reflexes (O), and right and left ankle jerks (+1). Questions: 1. How might an occupational therapist help James? 2. What is the average lifespan of an individual with Duchenne muscular dystrophy, and what are some of the more common causes of death in individuals with this disease? 3. How might Duchenne muscular dystrophy be treated 10 years from now? (Speculate on possible new treatments for this condition.)
