S3L2 : Muscular Dystrophies, Hydrocephalus, Chromosomal anomalies Flashcards
Clinical characteristics of DMD
- Hypertrophy of claves
- Progressive weakness
- Intellectual impairment
- Proliferation of connective tissue in muscles
T/F IN DMD,
- Fair head control: first sign of weakness
- Gower’s sign - evident at 2 y/o ; Prone –> Sitting
FF
Poor head control: first sign of weakness
Gower’s sign - evident at 3 y/o ; Prone –> Sitting
AGE OF ONSET OF DMD
3-5 y/o
Identify the wrong statement in DMD
- MAY SHOW SOME DEGREE OF WEAKNESS
- (+) GOWER’S SIGN
- WEAKNESS: LE> UE: GMAX
- CONTRACTURE: UE > LE PROXIMAL –> DISTAL
CONTRACTURE: LE > UE DISTAL –> PROXIMAL
Life expectancy of DMD
18-25 y/o
Suggested PT goals except
A. Maintain and/or Improve Flexibility
B. Improve Endurance and Breathing
C. Teach Wheelchair mobility activities
D. Improve Respiratory Hygiene
E. None
E
The ff. Are true in age 10-12 y/o, except
A. WHEEL CHAIR BOUND: MOTORIZED, JOYSTICK
B. DEVELOP SCOLIOSIS –> RESTRICTIVE LUNG DISEASE
C. PRONE TO APNEA –> BIPAP / CPA
D. None
D
T/F you can give mechanical resistive exercises to DMD pts.
F
Identify the muscular dystrophy
- Lack of dystrophin
- Milder form
Becker’s muscular dystrophy
Identify the muscular dystrophy
- X-linked recessive progressive dystrophic myopathy with gene locus Xp28.
- Deficient protein: Emerin
Emery dreifus muscular dystrophy
Identify the wrong statement in DMD
Age of onset: 3-5 y/o
Age of survival: 18-25 y/o
Contractures: early onset
Scoliosis: slower
MR: (+)
Scoliosis: faster
Identify the wrong statement in BMD
Age of onset: 10-20 y/o
Age of survival: mid-adult
Contractures: late onset
Scoliosis: slower
MR: (-)
Age of onset: 10-15 y/o
T/F. Emery dreifus muscular dystrophy Presents with:
- selective scapulohumeral peroneal distribution weakness
- striking wasting of the biceps
- sparing of the deltoids
False
NOTE: FA is spared along with deltoids
T/F. Etiology of emery dreifus MD includes
* X-linked recessive (Xq28)
* Autosomal dominance (1q)
T
Clinical manifestations of Emery dreifus MD include, except:
Onset: 5-15 y/o
(+) contractures of elbow & knee
(+) scapulohumeroperoneal muscle wasting
(+) normal intellectual function
(-) severe cardiomyopathy
Hypertrophy of muscles
Facial weakness
Myotonia
(+) severe cardiomyopathy
Lab findings of Emery dreifus MD
Serum CK: mildly elevated
Muscle biopsy
Prognosis of Emery dreifus MD
Slow progression
Most survive to late adult
Management of Emery dreifus MD
Supportive treatments
Special attention to cardiac conduction defects
Identify the muscular dystrophy
Symptoms are apparent during late school-age or adolescent period, about 10 years of age.
M=F
affects the muscles of the face and shoulder
Fascioscapulohumeral muscular dystrophy
Identify the muscular dystrophy
Clinical features
- Less common
1:30,000 live male birth - Less severe
- Family history: atypical MD
- Similar & less severe than DMD
- Onset: age > 7 yrs.
- Pseudohypertrophy of calf
- Equinus & varus foot
- High rate of scoliosis
- Less frequent cardiac involvement
Limb girdle muscular dystrophy
Identify the muscular dystrophy
AKA: STEINERT’S DISEASE CLINICAL
Myotonic muscular dystrophy
Identify the muscular dystrophy
AKA: SWARTZ-JAMPEL
Myotonic chondrodystrophy
Identify the muscular dystrophy
AKA: Thomsen’s disease ; Infantile Hercules
Myotonic congenita
The predominant manifestation of Fascioscapulohumeral muscular dystrophy is being unable to:
- whistle and wrinkle his or her forehead,
- close eyes tightly
- and raise arms.
