Bulbar palsy- MedGen UID:
- 898626
- •Concept ID:
- C4082299
- •
- Disease or Syndrome
Bulbar weakness (or bulbar palsy) refers to bilateral impairment of function of the lower cranial nerves IX, X, XI and XII, which occurs due to lower motor neuron lesion either at nuclear or fascicular level in the medulla or from bilateral lesions of the lower cranial nerves outside the brain-stem. Bulbar weakness is often associated with difficulty in chewing, weakness of the facial muscles, dysarthria, palatal weakness and regurgitation of fluids, dysphagia, and dysphonia.
Weakness of facial musculature- MedGen UID:
- 98103
- •Concept ID:
- C0427055
- •
- Disease or Syndrome
Reduced strength of one or more muscles innervated by the facial nerve (the seventh cranial nerve).
Distal muscle weakness- MedGen UID:
- 140883
- •Concept ID:
- C0427065
- •
- Finding
Reduced strength of the musculature of the distal extremities.
Increased variability in muscle fiber diameter- MedGen UID:
- 336019
- •Concept ID:
- C1843700
- •
- Finding
An abnormally high degree of muscle fiber size variation. This phenotypic feature can be observed upon muscle biopsy.
Rimmed vacuoles- MedGen UID:
- 340089
- •Concept ID:
- C1853932
- •
- Finding
Presence of abnormal vacuoles (membrane-bound organelles) in the sarcolemma. On histological staining with hematoxylin and eosin, rimmed vacuoles are popcorn-like clear vacuoles with a densely blue rim. The vacuoles are often associated with cytoplasmic and occasionally intranuclear eosinophilic inclusions.
Fatty replacement of skeletal muscle- MedGen UID:
- 866735
- •Concept ID:
- C4021082
- •
- Finding
Muscle fibers degeneration resulting in fatty replacement of skeletal muscle fibers
EMG: myopathic abnormalities- MedGen UID:
- 867362
- •Concept ID:
- C4021726
- •
- Pathologic Function
The presence of abnormal electromyographic patterns indicative of myopathy, such as small-short polyphasic motor unit potentials.
Increased endomysial connective tissue- MedGen UID:
- 867771
- •Concept ID:
- C4022161
- •
- Finding
An increased volume of the endomysium, which is a connective tissue sheath that surrounds each muscule fiber. Together, bundles of muscle fibers form a fasciculus, surrounded by another layer of connective tissue called the perimysium.
Elevated circulating creatine kinase concentration- MedGen UID:
- 69128
- •Concept ID:
- C0241005
- •
- Finding
An elevation of the level of the enzyme creatine kinase (also known as creatine phosphokinase (CK; EC 2.7.3.2) in the blood. CK levels can be elevated in a number of clinical disorders such as myocardial infarction, rhabdomyolysis, and muscular dystrophy.
Ptosis- MedGen UID:
- 2287
- •Concept ID:
- C0005745
- •
- Disease or Syndrome
The upper eyelid margin is positioned 3 mm or more lower than usual and covers the superior portion of the iris (objective); or, the upper lid margin obscures at least part of the pupil (subjective).
External ophthalmoplegia- MedGen UID:
- 57662
- •Concept ID:
- C0162292
- •
- Disease or Syndrome
Paralysis of the external ocular muscles.
- Abnormality of metabolism/homeostasis
- Abnormality of the eye
- Abnormality of the musculoskeletal system
- Abnormality of the nervous system
