ELECTRICAL STIMULATION OF THE GLOBUS PALLIDUS INTERNUS IN PATIENTS WITH PRIMARY GENERALIZED DYSTONIA: LONG-TERM RESULTS. J NEUROSURG. 2004. 101:189-194. SUMMARY: PRIMARY GENERALIZED DYSTONIA (PGD) IS A MEDICALLY REFRACTORY DISEASE OF THE BRAIN CAUSING TWISTING OR SPASMODIC MOVEMENTS AND ABNORMAL POSTURES. IN MORE THAN 30% OF CASES IT IS ASSOCIATED WITH THE AUTOSOMAL DYT1 MUTATION. CONTINUOUS ELECTRICAL STIMULATION OF THE GLOBUS PALLIDUS INTERNUS (GPI) HAS BEEN USED SUCCESSFULLY IN THE TREATMENT OF PGD. THE AIM OF THIS STUDY WAS TO EXAMINE THE LONG-TERM EFFICACY AND SAFETY OF DEEP BRAIN STIMULATION (DBS) IN THE TREATMENT OF PGD IN CHILDREN AND ADULTS WITH AND WITHOUT THE DYT1 MUTATION. REPORTED EVENTS: ONE (B)(6) PATIENT WITH BILATERAL GLOBUS PALLIDUS INTERNUS (GPI) DEEP BRAIN STIMULATION (DBS) FOR PRIMARY GENERALIZED DYSTONIA, WHO WAS NOTED TO BE BEDRIDDEN, EXPERIENCED A DELAYED UNILATERAL INFECTION OF THE IMPLANTABLE NEUROSTIMULATOR (INS) WITH STAPHYLOCOCCUS EPIDERMIDIS. THE SYSTEM WAS EXPLANTED AND REIMPLANTED 6 MONTHS LATER, RESULTING IN CLINICAL IMPROVEMENT. THE PATIENT'S SYMPTOMS REPORTEDLY RECURRED WITHIN ONE WEEK (OF EXPLANT), BUT DISAPPEARED QUICKLY ON REACTIVATION OF STIMULATION. THE AUTHORS NOTED THAT PATIENTS WERE BILATERALLY IMPLANTED WITH A PAIR OF 3389 ELECTRODES, WHICH WERE CONNECTED TO EITHER AN ITREL II OR III NEUROSTIMULATOR. IT WAS NOT POSSIBLE TO ASCERTAIN SPECIFIC DEVICE INFORMATION FROM THE ARTICLE (SUCH AS SERIAL NUMBERS) OR TO MATCH THE REPORTED EVENT WITH ANY PREVIOUSLY REPORTED EVENT.
