Correspondence To the Editor: The term myoclonus refers to a form of fast, transient, lightning‑like muscle twitch that originates in the nervous system. It is usually a manifestation of neurological dysfunction or intractable epilepsy and is clinically divided into cortical myoclonus, spinal myoclonus, physiological myoclonus, etc. It is also categorized as epileptic myoclonus or nonepileptic ...

This case series provides a diagnosis of myoclonus-dystonia syndrome (MDS) in two patients whose original presentation was thought to be Tourette’s syndrome. The first patient presented with dystonia and myoclonus, which progressively worsened age, diagnosed an epsilon-sarcoglycan gene (SGCE) mutation. patient’s father, who his childhood syndrome, also received genetic testing, proved that misd...

BACKGROUND Negative myoclonus is characterized by a brief sudden loss of muscle activity, and can be caused by a variety of acquired factors and epilepsy syndromes. PHENOMENOLOGY SHOWN We show a clear video example of a patient with an extensive negative myoclonus that was induced by ciprofloxacin. EDUCATIONAL VALUE Several neurotoxic effects have been associated with the use of ciprofloxac...

Lance–Adams syndrome (LAS) is a chronic post-hypoxic myoclonus that occurs after successful cardiopulmonary resuscitation. Although many drugs are available to treat this condition, the underlying mechanism of disease yet be understood. Deep brain stimulation (DBS) has been attempted and proven partially in treating LAS several cases. Here, we present 40-year-old woman who developed subsequent ...

Rhythmic myoclonus in an arm began abruptly following an injury and persisted continuously for six years. Topographical EMG showed abnormal activity confined to muscles innervated by the axillary and radial nerves from the posterior cord of the brachial plexus. Abduction of the arm above horizontal level stopped myoclonus and EMG discharges. EEG was normal. It is suggested that the myoclonus wa...

The clinical and electrophysiological features of segmental myoclonus affecting the right arm and upper trunk are described in a patient with multiple sclerosis. Electrophysiological studies suggested that the myoclonus was propagated from a generator site in the cervical cord, where lesions were found using MRI. The spread of electromyographic activity in each myoclonic jerk was slow and varia...

We report the case of a 38-year-old woman with AIDS who developed opsoclonus-myoclonus-ataxia syndrome during a period different from other cases reported in literature. Opsoclonus-myoclonus-ataxia syndrome had already been reported as the initial neurological presentation of AIDS, as well as at the time of HIV-seroconversion and immune reconstitution syndrome. Our case is unique since the pati...

Introduction: Etomidate, the imidazole derivative, is an intravenous anaesthetic induction agent, having stable hemodynamic profile, minimal respiratory side effects and histamine release. It is extremely useful in hemodynamically compromised patients. But the most common problem associated with its induction is myoclonus. Objective: To determine the effect of pretreatment with midazolam on the...

Myoclonus, seizures and progressive dementia are the main clinical features in Lafora's disease. This is the first reported case in which the diagnosis has been made by axillary skin biopsy in a patient with myoclonus but no other neurological symptoms.

BACKGROUND Etomidate frequently induces myoclonus when administered intravenously with bolus injection during anesthetic induction. This can be bothersome for the anesthesiologist. The dose of remifentanil appropriate for preventing myoclonus without side effects was investigated. METHODS All patients with American Society of Anesthesiologists (ASA) physical status I-III were divided into thr...
