Question 1
1 out of 1 points
Jordan is now 19-years old. As an infant, Jordan reached many gross motor skill
milestones, such as holding his head up, rolling over, sitting, and standing, at normal
times. However, he was considered a “late walker” because he took his first steps at 17
months. By 2 years old, his parents noticed a hyperlordotic posture while he was
standing. A Gower's sign and Trendelenberg gait were noted by age four. Throughout his
childhood, he suffered progressive muscle weakness, especially in the proximal
musculature of the arms, pelvis, and legs. He required orthotic braces to assist his walking
and was confined to wheelchair ambulation by age 13.
At 16, he was hospitalized with bronchitis requiring antibiotic treatment, but recovered.
Jordan has a history of progressive muscle weakness, but no history of muscle pain or
spasm, chest pain, or irregular heartbeat. The only medications that he normally takes
are calcium and fluoride supplements. Jordan has three siblings. His older and younger
sisters have never had any major medical issues. Jordan’s older brother is also to a
wheelchair with problems similar to Jordan's. No other immediate or distant family
members have musculoskeletal issues.
Jordan’s history aligns most closely with which diagnosis?
Selected Duchenne muscular
Answer:
dystrophy
Question 2

Jordan had a biopsy of the left gastrocnemius muscle when he was 5 years old. Based on
your answer for his diagnosis, describe the microscopic pathological changes that the
pathologist would have noted in her report.
Selected The pathologist would have noted that the small muscle fibers would be
Answer:
rounded, or polygonal, and there would be occasional
hypertrophic fibers. Noted to be groups of small necrotic and regenerating
muscle fibers. The nuclei would occasionally be internal, and the
endomysial connective tissue would be mildly increased. Finally the
perimysium would show early indications of being replaced by fat.
