See the published version at https://doi.org/10.1016/j.jiac.2019.09.007. Page 1/9 Abstract Background Neurosyphilis is a great imitator because of its various clinical symptoms. Syphilitic myelitis is extremely rare manifestation of neurosyphilis and often misdiagnosed. However, a small amount of literature in the past described its clinical manifestations and imaging features, and there was no relevant data on the prognosis, especially the long-term prognosis. In this paper, 4 syphilis myelitis patients admitted to our hospital between July 2012 and July 2017 were retrospectively reviewed. In the 4 patients, 2 were females, and 2 were males. We present our experiences with syphilitic myelitis, discuss the characteristics, treatment and prognosis. Case presentation The diagnosis criteria were applied: (1) diagnosis of myelitis established by two experienced neurologist based on symptoms and longitudinally extensive transverse myelitis (LETM) at the cervical and thoracic levels mimicked neuromyelitis optic (NMO) on magnetic resonance imaging (MRI) ; (2) Neurosyphilis (NS) was diagnosed by positive treponema pallidum particle assay (TPPA) and toluidine red untreated serum test (TRUST) in the serum and CSF; (3) negative human immunodeciency virus (HIV).

    Journal of Clinical Medicine Review Degenerative Cervical Myelopathy: Clinical Presentation, Assessment, and Natural History Melissa Lannon and Edward Kachur * Division of Neurosurgery, McMaster University, Hamilton, ON L8S 4L8, Canada; [email protected] * Correspondence: [email protected] Abstract: Degenerative cervical myelopathy (DCM) is a leading cause of spinal cord injury and a major contributor to morbidity resulting from narrowing of the spinal canal due to osteoarthritic changes. This narrowing produces chronic spinal cord compression and neurologic disability with a variety of symptoms ranging from mild numbness in the upper extremities to quadriparesis and incontinence. Clinicians from all specialties should be familiar with the early signs and symptoms of this prevalent condition to prevent gradual neurologic compromise through surgical consultation, where appropriate. The purpose of this review is to familiarize medical practitioners with the pathophysiology, common presentations, diagnosis, and management (conservative and surgical) for DCM to develop informed discussions with patients and recognize those in need of early surgical referral to prevent severe neurologic deterioration.

  • A Histopathological and Immunohistochemical Study of Acute and Chronic Human Compressive Myelopathy
    Cellular Pathology and Apoptosis in Experimental and Human Acute and Chronic Compressive Myelopathy ROWENA ELIZABETH ANNE NEWCOMBE M.B.B.S. B.Med Sci. (Hons.) Discipline of Pathology, School of Medical Sciences University of Adelaide June 2010 A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy CHAPTER 1 INTRODUCTION 1 The term “compressive myelopathy” describes a spectrum of spinal cord injury secondary to compressive forces of varying magnitude and duration. The compressive forces may act over a short period of time, continuously, intermittently or in varied combination and depending on their magnitude may produce a spectrum varying from mild to severe injury. In humans, spinal cord compression may be due to various causes including sudden fracture/dislocation and subluxation of the vertebral column, chronic spondylosis, disc herniation and various neoplasms involving the vertebral column and spinal canal. Neoplasms may impinge on the spinal cord and arise from extramedullary or intramedullary sites. Intramedullary expansion producing a type of internal compression can be due to masses created by neoplasms or fluid such as the cystic cavitation seen in syringomyelia. Acute compression involves an immediate compression of the spinal cord from lesions such as direct trauma. Chronic compression may develop over weeks to months or years from conditions such as cervical spondylosis which may involve osteophytosis or hypertrophy of the adjacent ligamentum flavum. Compressive myelopathies include the pathological changes from direct mechanical compression at one or multiple levels and changes in the cord extending multiple segments above and below the site of compression. Evidence over the past decade suggests that apoptotic cell death in neurons and glia, in particular of oligodendrocytes, may play an important role in the pathophysiology and functional outcome of human chronic compressive myelopathy.

  • Autoimmune Neurological Disorders - Does the Age Matter?
    1 Autoimmune neurological disorders - does the age matter? Yael Hacohen1,2 and Angela Vincent3 1. Department of Paediatric Neurology, Great Ormond Street Hospital for Children, London, 2. Department of Neuroinflammation, Queen Square MS Centre, UCL Institute of Neurology, London. 3. Nuffield Department of Clinical Neurosciences, John Radcliffe Hospital, Oxford. Antibodies binding to central nervous system (CNS) channels, receptors and other synaptic or glial proteins are now recognised as a likely cause of neurological disorders in both adults and children (see Table). Autoimmune encephalopathies are characterized variously by impaired alertness, amnesia, seizures, movement disorders, psychiatric features or autonomic instability, but without focal neurological deficits. The neuronal cell-surface antigens are essential to cellular function or neurotransmission and are generally expressed throughout the nervous system1. Autoimmune forms of demyelinating disorders, by contrast, can present as optic neuritis, transverse myelitis or a range of CNS presentations reflecting the site of the lesions. The glial (myelin or astrocyte) cell-surface antigens are widely expressed throughout the CNS. All these patients frequently respond well to immunotherapies, and in some cases the disorders are monophasic and do not require long-term immunosuppression2. By contrast, the typical paraneoplastic antibodies are generated against tumour antigens that are shared with the nervous system, and are usually associated with T cell-mediated pathogenic mechanisms; the antibodies represent an epiphenomenon of the disease but can be useful biomarkers for the existence of the appropriate tumour. Unfortunately, patients with the intracellular antibodies often progress relentlessly and do not respond to immunotherapies3. The strongest levels of evidence linking identified cell surface antibodies to the pathology of specific disorders are found with AQP4 antibody in neuromyelitis optica spectrum disorder and NMDAR antibody in NMDAR-antibody encephalitis.

  • Transverse Myelitis Interagency Collaboration
    SHNIC Specialized Health Needs Factsheet: Transverse Myelitis Interagency Collaboration What is it? Transverse Myelitis is a neurological disorder caused by inflammation of the spinal cord. A child will experience weakness, pain, sensory and autonomic dysfunction. Auto- nomic, involuntary activities such as breathing, digestion, heartbeat and reflexes can be affected. Symptoms can ap- pear suddenly within hours or progress over a span of sev- eral weeks. Approximately 25% of cases are children. A peak in incidence occurs between ages of 10 and 19 and females are at higher risk than men. During an inflammato- ry response the myelin, or protective fatty coating on nerve cells, is damaged or destroyed. TM can also be the first symptom to diagnose Multiple Sclerosis. What causes it? Researchers believe it is the body’s immune response, not the infection itself, that causes the inflammatory response. This indicates an auto-immune reaction, where the body attacks it’s own tissue rather than the infection, is responsible. Research has made connections to the damage of spinal nerves following a viral or bacterial infection, especially those associated with a rash. According to the National Institute of Neurologic Disorders and Stroke, infectious agents sus- pected of causing TM include Varicella zoster (the virus that causes chickenpox and shingles), Herpes simplex, Cytomegalovirus, Epstein-Barr, Influenza, Echovirus, Human immunodefi- ciency virus (HIV), Hepatitis A, and Rubella. In some cases, bacterial infections like a middle ear infection and bacterial pneumonia have also been linked. What are the symptoms? Symptoms can start slowly and progressively worsen over hours or days. Damage depends on the affected area of the spinal cord.

  • The Transverse Myelitis Association ...Advocating for Those with Acute Disseminated Encephalomyelitis, Neuromyelitis Optica, Optic Neuritis and Transverse Myelitis
    The Transverse Myelitis Association ...advocating for those with acute disseminated encephalomyelitis, neuromyelitis optica, optic neuritis and transverse myelitis ACUTE DISSEMINATED ENCEPHALOMYELITIS (ADEM) OVERVIEW Acute Disseminated Encephalomyelitis (ADEM) is a rare inflammatory demyelinating disease of the central nervous system. ADEM is thought to be an autoimmune disorder in which the body’s immune system mistakenly attacks its own brain tissue, triggered by an environmental stimulus in genetically susceptible individuals. More often it is believed to be triggered by a response to an infection or to a vaccination. For this reason, ADEM is sometimes referred to as post-infectious or post-immunization acute disseminated encephalomyelitis. EPIDEMIOLOGY According to a study published in 2008, the estimated incidence in California is 0.4 per 100,000 population per year, and there are approximately 3 to 6 ADEM cases seen each year at regional medical centers in the US, UK, and Australia2. ADEM is more common in children and adolescents than it is in adults, and there does not seem to be a higher incidence of ADEM among males or females, nor does there seem to be a higher frequency among any particular ethnic group. Post-infectious – In approximately 50-75 percent of ADEM cases, the inflammatory attack is preceded by a viral or bacterial infection. There have been a large number of viruses associated with these infections, including but not limited to: measles, mumps, rubella, varicella zoster, Epstein-Barr, cytomegalovirus, herpes simplex, hepatitis A, influenza, and enterovirus infections. A seasonal distribution has been observed showing that most ADEM cases occur in the winter and spring.

    Inflammation of the Central Nervous System- Encephalitis, Myelitis, and Meningitis Stacy Dillard, DVM, Diplomate ACVIM (Neurology) Inflammation of the central nervous system is a very common condition seen in veterinary neurology. The area in which the inflammation predominates indicates which of the clinical syndromes we use to name the disease. Inflammation involving the brain is called encephalitis, of the spinal cord is called myelitis and of the meninges is called meningitis. It is common to have more than one area of the central nervous system affected and therefore combinations of the names are often used such as meningoencephalomyelitis or meningoencephalitis. Encephalitis is the most common area of the central nervous system to be affected and will be used as the general term in this article. Etiology There are two main classes of encephalitis: infectious and idiopathic. Infectious etiologies include viruses, fungi, bacteria, protozoa, tick borne diseases and even algae. True infectious encephalitis is much less common in the dog than in other species including humans; however diagnosis is critical for proper targeted therapy. Idiopathic encephalitis means that an infectious etiology has not been found and encompasses a wide range of syndromes appreciated in the canine patient. Many idiopathic encephalitidies are thought to be immune-mediated and respond well to immune-suppression. Other idiopathic encephalitis, such as necrotizing encephalitis found in young toy breed dogs, do not appear to respond as well to immuno- suppression and therefore may represent another form of the disease. Idiopathic encephalitis is much more common in the dog than infectious encephalitis; however, definitive diagnosis is critical as treatment is markedly different between the two categories of disease.
