We observed 37 patients (mean age at onset, 48.5 years; range, 13 to 84 years) with segmental myoclonus (18 branchial, 19 spinal). Etiologies for branchial myoclonus included brain-stem demyelination, cerebrovascular disease, Meige's syndrome, cerebral arteritis secondary to bacterial meningitis, central nervous system Whipple's disease, acute cervicomedullary trauma, and cerebellar degeneration. Spinal myoclonus was associated with laminectomy, remote effect of cancer, spinal cord injury, post-operative pseudomeningocele, laparotomy, thoracic sympathectomy, poliomyelitis, herpes myelitis, lumbosacral radiculopathy, spinal extradural block, and myelopathy due to demyelination, electrical injury, acquired immunodeficiency syndrome, and cervical spondylosis. The latency between the predisposing condition and the onset of myoclonus ranged from immediate to 33 years (mean, 2.9 years). In six patients, the myoclonus was the presenting symptom of a serious underlying disease. Treatment with clonazepam, tetrabenazine hydrochloride, or other medications provides a satisfactory control in most patients.

A 40-year-old female with a lumbar drain was admitted to the neurosurgery service with a bacterial meningitis. During the course of her treatment with multiple central nervous system (CNS) active medications, the patient became disoriented and agitated with visual hallucinations and generalized myoclonus. A psychiatric consultation was requested. The case is presented and discussed within the context of the importance of understanding etiological mechanisms in treating and reversing delirium. The fluoroquinolone agent ciprofloxacin was considered to be the primary etiology of the patient's delirium. This class of medication as a cause of altered mental status is discussed.

Male monozygotic twins with genetically determined severe myoclonic epilepsy in infancy are described. Although seizure onset, clinical seizure symptomatology, and motor and mental development were almost identical until age 38 months, their clinical courses then became discordant. The emergence of myoclonus was delayed by 12 months in twin 1 compared with twin 2. Regression in language development, which is a common feature of severe myoclonic epilepsy in infancy, was obvious in twin 2 after the emergence of myoclonus, whereas twin 1 did not demonstrate any regression. The clinical-course discordance between twins was attributable to bacterial meningitis, which twin 1 developed at age 35 months. Bacterial meningitis may have affected the clinical course of severe myoclonic epilepsy in infancy in twin 1, resulting in delayed onset of myoclonus and more favorable language development in twin 1 than in twin 2, who did not experience bacterial meningitis.

A 64-year-old man with fever, appetite loss, and pain in the back of the neck visited our hospital. We diagnosed him as having bacterial meningitis because of pleocytosis of the cerebrospinal fluid, and started treatment with antibiotics. Multiple cerebral infarcts were found on brain MRI. We suspected that the origin of the bacterial meningitis was infective endocarditis, and administered Cefepime and Gentamicin according to the guidelines for treatment of infective endocarditis. Three days later, he became drowsy and had myoclonus and flapping of the extremities. An electroencephalograph showed generalized periodic discharge and a triphasic wave pattern. We thought that the cause of disturbance in consciousness was Cefepime-induced encephalopathy, and stopped administration of Cefepime. A few days later, he became clear, and the myoclonus and flapping disappeared. It was difficult to distinguish between non-convulsive status epilepticus and Cefepime-induced encephalopathy. However, since stopping Cefepime treatment had made the patient clear, we diagnosed his condition as Cefepime-induced encephalopathy, which often occurs in patients with renal or liver dysfunction, or in brain infarction or meningitis, which results in blood-brain barrier disruption. Thus, care should be taken when administering Cefepime to such patients.
