Stereotactic Gamma Knife radiosurgery for the treatment of dystonia
Stereotactic and Functional Neurosurgery
|January 1, 1995
Abstract:
A case of dystonia treated with Gamma Knife radiosurgery is reported. A 37-year-old female patient had a history of tuberculous meningitis at the age of 10 and subsequently developed a left hemidystonia. MRI showed an old infarction in the right caudate nucleus, globus pallidus and putamen. Stereotactic Gamma Knife radiosurgery was employed to make a lesion in the right posteroventral globus pallidus. Postoperatively, the patient's condition improved. However, homonymous hemianopsia developed postoperatively.

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.

Skeletal Muscle Relaxants: Therapeutic Uses
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...
