Schwartz-Jampel Syndrome: Follow-up
Updated: Feb 2, 2007
Follow-up
Prognosis
- Except for the patients with Stuve-Wiedemann syndrome, which is fundamentally a different disease, most patients have a good prognosis.
- Muscle stiffness, muscle weakness, and skeletal abnormalities may worsen gradually or remain essentially stable.
Patient Education
- Because patients with SJS have a characteristic physical appearance, they may need extra psychosocial support.
- As in all diseases causing muscle stiffness, the danger exists of iatrogenic addiction to muscle relaxants such as diazepam (which is not particularly useful in this condition).
- If patients are treated with the medications listed in this article or with other medications, they should be educated about the adverse effects.
- The subset (as many as 20%) of patients who also have mental retardation require special education for that problem.
Miscellaneous
Medicolegal Pitfalls
- The tendency to malignant hyperthermia could lead to adverse outcomes in surgery.
- Cosmetic surgery to relieve the blepharospasm, blepharophimosis, and ptosis carries a medicolegal risk.
