We present a case of scrub typhus with a rare ophthalmic manifestation.Our patient presented with fever and opsoclonus, was diagnosed to have scrub typhus and completely improved upon treatment. [jpgmonline.com]

The clinical features described above may not always be present upon patient presentation, posing a diagnostic challenge. Because of this variability in presentation, a set of diagnostic criteria has been proposed by international collaborators. [aao.org]

Clinical description OMS typically presents between 1 and 3 years of age, although it can occur earlier or later in childhood. [orpha.net]

Here we present the case of a girl of 15 months with OMS associated with retroperitoneal ganglioneuroblastoma that improved after tumor resection and treatment with corticosteroids and immunoglobulin. [scielo.org.co]

For etiological clarification, a full workup was conducted with blood tests, including tumor markers and serology for human immunodeficiency virus, cytomegalovirus and Epstein Barr virus; brain magnetic resonance imaging (MRI), CT scan of the chest, abdomen [academic.oup.com]

In older adults, a full-scale workup for neoplasm is generally indicated and is productive in persons with opsoclonus. [dizziness-and-balance.com]

After 2 years of treatment, the patient is in complete remission and has no sequelae. Multiple treatment protocols for OMAS have been developed. [elsevier.es]

Treatment Treatment for opsoclonus myoclonus may include corticosteroids or ACTH (adrenocorticotropic hormone). In cases where there is a tumor present, treatment such as chemotherapy, surgery, or radiation may be required. [childneurologyfoundation.org]

Management and treatment Treatment usually includes resection of the neuroblastoma if present; occasionally, higher grade neuroblastoma may require chemotherapy. Treatment also includes immunomodulation. [orpha.net]

There is controversy about how treatment alters outcome. [pediatrics.aappublications.org]

This protocol will investigate an escalating treatment schedule starting with a corticosteroid standard treatment with dexamethasone pulses (first step), which is followed, if response has been inadequate after 3 months of treatment, by the addition of [centerwatch.com]

PROGNOSIS • The survival prognosis of children with OMS secondary to neuroblastoma is very favorable better than neuroblastoma without OMS • A monophasic course and that those patients generally had a more favorable neurologic prognosis than patients [slideshare.net]

Prognosis The prognosis for opsoclonus myoclonus varies depending on the symptoms and the presence and treatment of tumors. With treatment of the underlying cause of the disorder, there may be an improvement of symptoms. [childneurologyfoundation.org]

While the OMS is not a common pediatric pathology, its association with neoplastic disease is very strong and ignore its existence and clinical presentation may lead to delays or underdiagnosis of the tumor with negative impact on the prognosis of the [scielo.org.co]

There are no known criteria to predict prognosis. Corticosteroidor corticotropin are recommended treatment regimes. Conclusions.The boy with OMAS is described. The diagnosis was made in retrospect. [worldcat.org]

Trazodone has been reported to be beneficial and well tolerated for treatment of associated sleep disturbances or rage attacks. 29 Prognosis Overall, the survival prognosis of children with OMS secondary to neuroblastoma is very favorable. [aao.org]

The etiology was paraneoplastic in 13 (35.1%) cases, neuroblastoma being the most common tumor; a post-infectious etiology was seen in 5 cases; other etiologies were cerebral malaria, dengue, human immunodeficiency virus infection, scrub typhus and poisoning [neurologyindia.com]

Etiology OMS may have a paraneoplastic, parainfectious or idiopathic origin. In the majority of pediatric paraneoplastic cases, a neuroblastoma is found. [orpha.net]

After infectious and post-infectious etiologies were excluded the patient was screened for autoimmune and drug-related etiologies, without success. [karger.com]

There are reports of certain auto-antibodies associated with OMS, supporting the suspected etiology of an autoimmune reaction against central nervous system tissues. [aao.org]

Immunotherapy should be initiated along with a complete work up for underlying malignancy, infectious, systemic diseases and toxic etiology. [file.scirp.org]

While the pathophysiology is unknown, OMS is felt to be related to autoimmunity. As a result of cerebellar Purkinje cell dysfunction, oculomotor neurons of the caudal fastigial nucleus of the cerebellum become progressively disinhibited. [radiopaedia.org]
