Value of quantitative sensory testing in neurological and pain disorders: NEUPSIG consensus
Quantitative sensory testing (QST) is a psychophysical method used to quantify somatosensory function in response to controlled stimuli in healthy subjects and patients. Although QST shares similarities with the quantitative assessment of hearing or vision, which is extensively used in clinical practice and research,..Duloxetine and pregabalin: High-dose monotherapy or their combination?

Induction of Monocyte Chemoattractant Protein-1 (MCP-1) and Its Receptor CCR2 in Primary Sensory Neurons Contributes to Paclitaxel-Induced Peripheral Neuropathy
The use of paclitaxel (Taxol), a microtubule stabilizer, for cancer treatment is often limited by its associated peripheral neuropathy (chemotherapy-induced peripheral neuropathy [CIPN]), which predominantly results in sensory dysfunction, including chronic pain. Here we show that paclitaxel CIPN was associated with..Quality of life (QoL) in community-dwelling and institutionalized Alzheimer's disease (AD) patients

A rare cause of chronic sciatic pain: Schwannoma of the sciatic nerve
Schwannomas are common, benign tumors of the shelth of peripheral nerves. Sciatic schwannomas are rare. Their symptomatology usually mimics sciatic pain due to a herniated disc, which can delay the diagnosis. If there is no lumbar pain and lumbar MRI is normal, the sciatic nerve must be clinically and radiologically..Life-threatening hypokalemia following rapid correction of respiratory acidosis

Genetic expression profiles of adult and pediatric ependymomas: Molecular pathways, prognostic indicators, and therapeutic targets
Ependymomas are tumors that can present within either the intracranial or spinal regions. While 90% of all pediatric ependymomas are intracranial, spinal cord ependymomas are more commonly found in patients 20–40 years old.

Ketamine use in the treatment of refractory status epilepticus
Refractory status epilepticus (RSE) occurs when status epilepticus (SE) fails to respond to appropriate therapy with typical antiepileptic drugs (AEDs). Animal studies have shown ketamine to be a highly efficacious agent in this setting, but very few case reports describe use of ketamine in human SE or RSE.

Mislocalization of AQP4 precedes chronic seizures in the kainate model of temporal lobe epilepsy
It has been suggested that loss of the astrocytic water channel aquaporin-4 (AQP4) from perivascular endfeet in sclerotic hippocampi contributes to increased seizure propensity in human mesial temporal lobe epilepsy (MTLE). Whether this loss occurs prior to or as a consequence of epilepsy development remains to be..MRI findings after hyperbaric oxygen-induced seizures

Orthostatic hypotension among outpatients with ischemic stroke
Background: The treatment of hypertension is an essential component of stroke prevention; however, the clinical management of patients with cerebrovascular disease is complicated by orthostatic hypotension (OH). The primary objectives were to: determine the prevalence of OH in a stroke outpatient clinic; describe..Pridopidine for the treatment of motor function in patients with Huntington's disease (MermaiHD): a phase 3, randomised, double-blind, placebo-controlled trial

Pridopidine for the treatment of motor function in patients with Huntington's disease (MermaiHD): a phase 3, randomised, double-blind, placebo-controlled trial
Background: Huntington's disease is a progressive neurodegenerative disorder, characterised by motor, cognitive, and behavioural deficits. Pridopidine belongs to a new class of compounds known as dopaminergic stabilisers, and results from a small phase 2 study in patients with Huntington's disease suggested that this..Noise on, voicing off: Speech perception deficits in children with specific language impairment

Noise on, voicing off: Speech perception deficits in children with specific language impairment
Speech perception of four phonetic categories (voicing, place, manner, and nasality) was investigated in children with specific language impairment (SLI) (n = 20) and age-matched controls (n = 19) in quiet and various noise conditions using an AXB two-alternative forced-choice paradigm. Children with SLI exhibited..Modafinil treatment prevents REM sleep deprivation-induced brain function impairment by increasing MMP-9 expression

Modafinil treatment prevents REM sleep deprivation-induced brain function impairment by increasing MMP-9 expression
Previous work showed that sleep deprivation (SD) impairs hippocampal-dependent cognitive function and synaptic plasticity, and a novel wake-promoting agent modafinil prevents SD-induced memory impairment in rat. However, the mechanisms by which modafinil prevented REM-SD-induced impairment of brain function remain..Mycoplasmal cerebral vasculopathy in a lymphoma patient: Presumptive evidence of Mycoplasma pneumoniae microvascular endothelial cell invasion in a brain biopsy.

Mycoplasmal cerebral vasculopathy in a lymphoma patient: Presumptive evidence of Mycoplasma pneumoniae microvascular endothelial cell invasion in a brain biopsy.
A 73-year-old man had episodic encephalopathy, ataxia and neuropathy. Symptoms largely resolved but adenopathy later lead to the diagnosis of a low-grade follicular lymphoma. The neurological symptoms soon recurred with new pontine calcifications identified by computed tomography. Brain biopsy revealed microvascular..Gerstmann–Sträussler–Scheinker syndrome masquerading multiple sclerosis

Gerstmann–Sträussler–Scheinker syndrome masquerading multiple sclerosis
Gerstmann–Sträussler–Scheinker syndrome (GSS) is a rare degenerative disorder of the central nervous system that belongs to the family of human spongiform encephalopathies, or prion diseases. GSS is almost always inherited and mostly carried in an autosomal dominant pattern. Nevertheless, GSS is genetically and..
