Pes planus- MedGen UID:
- 42034
- •Concept ID:
- C0016202
- •
- Anatomical Abnormality
A foot where the longitudinal arch of the foot is in contact with the ground or floor when the individual is standing; or, in a patient lying supine, a foot where the arch is in contact with the surface of a flat board pressed against the sole of the foot by the examiner with a pressure similar to that expected from weight bearing; or, the height of the arch is reduced.
Pes cavus- MedGen UID:
- 675590
- •Concept ID:
- C0728829
- •
- Congenital Abnormality
An increase in height of the medial longitudinal arch of the foot that does not flatten on weight bearing (i.e., a distinctly hollow form of the sole of the foot when it is bearing weight).
Hammertoe- MedGen UID:
- 209712
- •Concept ID:
- C1136179
- •
- Anatomical Abnormality
Hyperextension of the metatarsal-phalangeal joint with hyperflexion of the proximal interphalangeal (PIP) joint.
Fasciculations- MedGen UID:
- 5124
- •Concept ID:
- C0015644
- •
- Sign or Symptom
Fasciculations are observed as small, local, involuntary muscle contractions (twitching) visible under the skin. Fasciculations result from increased irritability of an axon (which in turn is often a manifestation of disease of a motor neuron). This leads to sporadic discharges of all the muscle fibers controlled by the axon in isolation from other motor units.
Tremor- MedGen UID:
- 21635
- •Concept ID:
- C0040822
- •
- Sign or Symptom
An unintentional, oscillating to-and-fro muscle movement about a joint axis.
Areflexia- MedGen UID:
- 115943
- •Concept ID:
- C0234146
- •
- Finding
Absence of neurologic reflexes such as the knee-jerk reaction.
Hyporeflexia- MedGen UID:
- 195967
- •Concept ID:
- C0700078
- •
- Finding
Reduction of neurologic reflexes such as the knee-jerk reaction.
Distal sensory impairment- MedGen UID:
- 335722
- •Concept ID:
- C1847584
- •
- Finding
An abnormal reduction in sensation in the distal portions of the extremities.
Spinal muscular atrophy- MedGen UID:
- 7755
- •Concept ID:
- C0026847
- •
- Disease or Syndrome
Spinal muscular atrophy (SMA) is characterized by muscle weakness and atrophy resulting from progressive degeneration and irreversible loss of the anterior horn cells in the spinal cord (i.e., lower motor neurons) and the brain stem nuclei. The onset of weakness ranges from before birth to adulthood. The weakness is symmetric, proximal > distal, and progressive. Before the genetic basis of SMA was understood, it was classified into clinical subtypes based on maximum motor function achieved; however, it is now apparent that the phenotype of SMN1-associated SMA spans a continuum without clear delineation of subtypes. With supportive care only, poor weight gain with growth failure, restrictive lung disease, scoliosis, and joint contractures are common complications; however, newly available targeted treatment options are changing the natural history of this disease.
Muscle spasm- MedGen UID:
- 52431
- •Concept ID:
- C0037763
- •
- Sign or Symptom
Sudden and involuntary contractions of one or more muscles.
Muscle weakness- MedGen UID:
- 57735
- •Concept ID:
- C0151786
- •
- Finding
Reduced strength of muscles.
Difficulty walking- MedGen UID:
- 86319
- •Concept ID:
- C0311394
- •
- Finding
Reduced ability to walk (ambulate).
Muscular atrophy- MedGen UID:
- 892680
- •Concept ID:
- C0541794
- •
- Pathologic Function
The presence of skeletal muscular atrophy (which is also known as amyotrophy).
Calf muscle hypertrophy- MedGen UID:
- 335868
- •Concept ID:
- C1843057
- •
- Finding
Muscle hypertrophy affecting the calf muscles.
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.
