Severe neuropathy is a known adverse effect of vincristine in patients with Charcot-Marie-Tooth disease (CMT). We present the case of a 16-year-old girl with anaplastic medulloblastoma treated with gross total resection and high-dose craniospinal radiation with adjuvant vincristine chemotherapy who developed acute-onset severe quadriplegia and vocal cord paralysis. Vincristine and radiation therapy were discontinued. Although her neuropathy slowly improved over several weeks, she developed metastatic extraneural medulloblastoma and died 5 months after diagnosis...

An 80-year-old man developed dysarthria, quadriplegia, sensory disturbance and ataxia in all limbs. Brain and spinal magnetic resonance imaging (MRI) revealed multiple enhanced lesions. Cerebrospinal fluid (CSF) levels of adenosine deaminase (ADA) remarkably elevated. Tuberculosis DNA was not detected, and tuberculosis was not cultured either in the CSF. Brain biopsy revealed the inflammatory demyelinating lesions. With the diagnosis of multiple sclerosis, corticosteroid therapy resulted in rapid improvement of his symptoms and MRI abnormalities...

Coxsackievirus A10 (CVA10) is one of the major pathogens associated with hand, foot and mouth disease (HFMD). CVA10 infection can cause herpangina and viral pneumonia, which can be complicated by severe neurological sequelae. Morbidity and mortality of CVA10-associated HFMD has been increasing in recent years, particularly in the pan-Pacific region. There are limited studies however on the pathogenesis and immunology of CVA10-associated HFMD infections, and few antiviral drugs or vaccines have been reported...

We report two cases of neuromyelitis optica spectrum disorder (NMOSD) who were misdiagnosed as multiple sclerosis (MS) and developed catastrophic relapses following initiation of dimethyl fumarate. Both patients developed a severe myelitis extending from the cervical cord to the medulla with significant cord swelling, resulting in complete quadriplegia and respiratory difficulties, in addition to severe bilateral visual loss in one patient. It is of note that both catastrophic relapses occurred 2 and 3 months following initiation of dimethyl fumarate...

CONTEXT: Patients with complete quadriplegia after high cervical spinal cord injury are fully dependent with activities of daily living. Assistive technology can improve their quality of life. We examined the use of a hybrid assistive limb for single joints (HAL-SJ) in a 19-year-old man with complete C4 quadriplegia due to chronic spinal cord injury to restore function of active elbow flexion. This is the first report on the use of the HAL-SJ in a patient with spinal cord injury. FINDINGS: The HAL-SJ intervention for each elbow was administered in 10 sessions...

BACKGROUND: Basilar artery occlusion can cause locked-in syndrome, which is characterized by quadriplegia, anarthria, and limited communication via eye movements. Here, we describe an uncommon stroke syndrome associated with endovascular recanalization of the top of the basilar artery: "reverse locked-in syndrome." METHODS: We report the case of a patient with atypical neurological deficits caused by acute ischemic stroke of the midbrain tegmentum. We perform neuroanatomic localization of the patient's infarcts by mapping the magnetic resonance imaging (MRI) data onto a brainstem atlas...

BACKGROUND Spinal cord ischemia is an uncommon event that is mainly caused by dissociation of the ascending aorta as a complication after aortic surgery. Spinal arteries can develop collateral circulation; therefore, the frequency of spinal infarction is about 1% of that in the brain. Few cases of spinal cord ischemia developing in the course of lung cancer have been reported. CASE REPORT We presented the case of a 56-year-old man with small cell lung carcinoma, cT4N2M1a (stage IV). He was treated with irradiation and 2 courses of platinum and etoposide combination chemotherapy...

Recent advances in Brain Computer Interfaces (BCIs) have created hope that one day paralyzed patients will be able to regain control of their paralyzed limbs. As part of an ongoing clinical study, we have implanted a 96-electrode Utah array in the motor cortex of a paralyzed human. The array generates almost 3 million data points from the brain every second. This presents several big data challenges towards developing algorithms that should not only process the data in real-time (for the BCI to be responsive) but are also robust to temporal variations and non-stationarities in the sensor data...

The biceps or the posterior deltoid can be transferred to improve elbow extension function for many individuals with C5 or C6 quadriplegia. Maximum strength after elbow reconstruction is variable; the patient's ability to voluntarily activate the transferred muscle to extend the elbow may contribute to the variability. We compared voluntary activation during maximum isometric elbow extension following biceps transfer (n = 5) and deltoid transfer (n = 6) in three functional postures. Voluntary activation was computed as the elbow extension moment generated during maximum voluntary effort divided by the moment generated with full activation, which was estimated via electrical stimulation...

Hand, foot and mouth disease (HFMD) is a global health concern. Family Picornaviridae members, particularly enterovirus 71 (EVA71) and Coxsackievirus A16 (CVA16), are the primary etiological agents of HFMD, however, a third enterovirus A species, CoxsackievirusA6 (CVA6), has been recently associated with epidemic outbreaks. Study of the pathogenesis of CVA6 infection and development of antivirals and vaccines are hindered due to the lack of appropriate animal models. We have developed and characterized a murine model of CVA6 infection which was employed to evaluate the antiviral activities of different drugs and the protective efficacies of CVA6-inactivated vaccines...

Spondylodiscitis affecting the cervical spine is the most unusual type. Disease progression can be dramatic, even causing quadriplegia and death. We present an unusual case that progressed with osteolytic lesions between C2 and C3, causing cord compression and epidural abscess. The patient was treated surgically by a double approach and improved without neurological deficits and with better inflammatory markers. We reviewed the current literature on the subject.
