What is opsoclonus myoclonus syndrome?

Definition. Opsoclonus myoclonus is a rare neurological disorder characterized by an unsteady, trembling gait, myoclonus (brief, shock-like muscle spasms), and opsoclonus (irregular, rapid eye movements). Other symptoms may include difficulty speaking, poorly articulated speech, or an inability to speak.

How common is opsoclonus myoclonus?

What causes opsoclonus myoclonus syndrome?

Causes of OMAS OMAS may be caused by an immune reaction to a tumor called neuroblastoma or an immune reaction to a viral illness. The immune reaction causes the body to produce antibodies to the cerebellum, which is located in the back of the brain.

What does opsoclonus look like?

Opsoclonus describes the dramatic occurrence of involuntary conjugate multidirectional saccades (saccadomania) that occur without an intersaccadic interval. The eye movement abnormality is often associated with eye blinking, facial twitching, myoclonus, and ataxia (Kinsbourne's “dancing eyes and dancing feet”).

What is a myoclonic seizure? Myoclonic (MY-o-KLON-ik) seizures are brief, shock-like jerks of a muscle or a group of muscles. "Myo" means muscle and "clonus" (KLOH-nus) means rapidly alternating contraction and relaxation—jerking or twitching—of a muscle. Usually they don't last more than a second or two.

Clinical description

OMS typically presents between 1 and 3 years of age, although it can occur earlier or later in childhood. It is characterized by opsoclonus (rapid, multi-directional, conjugate eye movements), myoclonic jerks, ataxia, irritability and sleep disturbances. The clinical course may be monophasic or chronic relapsing.

Etiology

OMS may have a paraneoplastic, parainfectious or idiopathic origin. In the majority of pediatric paraneoplastic cases, a neuroblastoma is found. Infections triggering OMS include a variety of viral and bacterial agents including streptococci, mycoplasma and varicella zoster.

Diagnostic methods

The diagnosis is clinical, based on the presence of 3 out of the 4 following criteria: 1) neuroblastoma, 2) opsoclonus, 3) a movement disorder with myoclonus and/or ataxia, and 4) behavioural and/or sleep disturbance. Brain MRI in the acute presentation is normal.

Differential diagnosis

Differential diagnosis includes acute inflammatory cerebellar ataxia that is differentiated from OMS by the type of eye movement (nystagmus), the absence of irritability, and the usually rapid recovery without treatment.

Management and treatment

Treatment usually includes resection of the neuroblastoma if present; occasionally, higher grade neuroblastoma may require chemotherapy. Treatment also includes immunomodulation. Treatment regimens have not been standardized but may include corticosteroids, adrenocorticotropin hormone, cyclophosphamide, intravenous immunoglobulin, and/or rituximab.

Prognosis

Outcome is variable. Some children have a monophasic illness, respond well to steroids and have little or no sequelae. Others may be treatment-resistant, have a chronic relapsing course and motor, cognitive and/or behavioral sequelae. Opsoclonus usually remits. The presence or absence of neuroblastoma does not seem to affect outcome.

What is the diagnosis of OMS?

A diagnosis of OMS is mostly based on the presence of the characteristic signs and symptoms. In some cases, laboratory tests for certain antibodies and/or for abnormal white blood cells may also be done. [3]

What are the symptoms of OMS?

Signs and symptoms of opsoclonus-myoclonus syndrome (OMS) may include: [2] [3] Unsteady, trembling gait (manner of walking) Sudden, brief, shock-like muscle spasms (myoclonus). While it occurs most when trying to move and worsens with agitation or stimulation, it can also be present at rest.

What is the treatment for OMS?

There are no official treatment recommendations for OMS. Management may involve: Surgery, chemotherapy, and/or radiation: When there is a tumor present, treatment such as surgery for tumor removal, chemotherapy, or radiation may be required. [2] . In children, the removal of the neuroblastoma does not always improve neurologic symptoms.

Opsoclonus-myoclonus treatment will also typically involve physical and occupational therapy to speed recovery.

How to confirm OMAS diagnosis?

To confirm an OMAS diagnosis, your child will have several tests to look for brain abnormalities and to look for a tumors in the body. A lumbar puncture is often performed to look for evidence of an immune response. Urine tests, including vanillylmandelic acid (VMA) and homovanillic acid (HVA) tests are performed to look for evidence of a tumor. ...

What is OMAS in medical terms?

What is opsoclonus-myoclonus-ataxia syndrome (OMAS)?
