A case is described in which the clinical and pathological features of amyotrophic lateral sclerosis (ALS) occurred in a patient with cysticercosis of the central nervous system and associated pachymeningitis of the cervical spinal cord. This is an extremely rare finding. The patient also presented the two symptom complexes more commonly encountered in this condition: focal and generalized epilepsy, and signs of obstructive hydrocephalus. The literature relevant to this case, and to cysticercosis in Great Britain, is briefly reviewed. The case described adds to the concept of motor neurone disease as a syndrome rather than a disease entity of undetermined aetiology.

In the present study we describe an ELISA to quantify the light subunit of the neurofilament triplet protein (NFL) in CSF. The method was validated by measuring CSF NFL concentrations in healthy individuals and in two well-characterized groups of patients with amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD). The levels were increased in ALS (1,743 +/- 1,661 ng/L; mean +/- SD) and AD (346 +/- 176 ng/L) compared with controls (138 +/- 31 ng/L; p < 0.0001 for both). Within the ALS group, patients with lower motor neuron signs only had lower NFL levels (360 +/- 237 ng/L) than those with signs of upper motor neuron disease (2,435 +/- 1,633 ng/L) (p < 0.05). In a second study patients with miscellaneous neurodegenerative diseases were investigated (vascular dementia, olivopontocerebellar atrophy, normal pressure hydrocephalus, cerebral infarctions, and multiple sclerosis), and the CSF NFL level was found to be increased (665 +/- 385 ng/L; p < 0.0001). NFL is a main structural protein of axons, and we suggest that CSF NFL can be used to monitor neurodegeneration in general, but particularly in ALS with involvement of the pyramidal tract.

We report a case of a rapidly progressive, fatal non-inflammatory demyelinating disease, distinct from multiple sclerosis and lysosomal disorders, in a patient with progressive dementia. Electron microscopy of stereotactic brain biopsy samples revealed the presence in neurons of sinuous, double-walled cylindrical membranous structures within the cisterns of the endoplasmic reticulum. These structures were 75-80 nm in overall diameter, up to 1.5 mm long and had a 40- to 45-nm diameter core. The possibility that they might be viruses of the Filoviridae or Paramyxoviridae families was considered, but the inclusions differed in key morphological aspects from members of both virus families and there were no supporting clinical or pathological data. Neither was it possible to assign the structures to any other known virus family on the basis of their morphology. Such inclusions have been the subject of only three published reports over the past 20 years. Evidence suggests that they may be confined to human central nervous system neurons, but occur in unrelated disorders (Alzheimer's disease, amyotrophic lateral sclerosis, meningoencephalitis, low-pressure hydrocephalus, demyelination). The possibility that they are formed in certain neurons by an abnormal internal budding process, as a response to a variety of pathological insults, is considered most likely, although an infectious origin (such as an unrecognised virus with variable clinical effect) cannot be ruled out.

The continuing expansion of proteomic technology has been fueled by the potential for discovering novel biomarkers that may be used for the early detection of disease. It has been proposed that human cerebrospinal fluid (CSF), which surrounds and protects the brain and spinal cord from traumatic injury, may be a valuable target for the diagnosis of a variety of conditions such as Alzheimer's disease, traumatic brain injury, amyotrophic lateral sclerosis and Parkinson's disease. The immense complexity of biofluids, however, still requires that considerable development be made in the analytical techniques used so that comprehensive coverage of the proteins present in such samples is achieved. Using a simple separation strategy the protein complement of human ventricular cerebrospinal fluid obtained from patients with hydrocephalus was evaluated. The study resulted in the identification of over 1500 unique proteins that were found within all nine CSF samples that were analyzed. Comparison with the HUPO serum proteome database demonstrated that human ventricular CSF contains a large array of proteins that may be unique to CSF. This analysis greatly increases our knowledge of the protein content of this clinically important biofluid.

The craniocervical junction (CCJ) is a potential choke point for craniospinal hydrodynamics and may play a causative or contributory role in the pathogenesis and progression of neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, MS, and ALS, as well as many other neurological conditions including hydrocephalus, idiopathic intracranial hypertension, migraines, seizures, silent-strokes, affective disorders, schizophrenia, and psychosis. The purpose of this paper is to provide an overview of the critical role of the CCJ in craniospinal hydrodynamics and to stimulate further research that may lead to new approaches for the prevention and treatment of the above neurodegenerative and neurological conditions.

Neurological conditions are among the leading causes of disability in the Canadian population and are associated with a large public health burden. An increase in life expectancy and a declining birth rate has resulted in an aging Canadian population, and the proportion of age-adjusted mortality due to non-communicable diseases has been steadily increasing. These conditions are frequently associated with chronic disability and an increasing burden of care for patients, their families and caregivers. The National Population Health Study of Neurological Conditions (NPHSNC) aims to improve knowledge about neurological conditions and their impacts on individuals, their families, caregivers and health care system. The Systematic Review of Determinants of Neurological Conditions, a specific objective within the NPHSNC, is a compendium of systematic reviews on risk factors affecting onset and progression of the following 14 priority neurological conditions: Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), brain tumours (BT), cerebral palsy (CP), dystonia, epilepsy, Huntington's disease (HD), hydrocephalus, multiple sclerosis (MS), muscular dystrophies (MD), neurotrauma, Parkinson's disease (PD), spina bifida (SB), and Tourette's syndrome (TS). The burden of neurological disease is expected to increase as the population ages, and this trend is presented in greater detail for Alzheimer's and Parkinson's disease because the incidence of these two common neurological diseases increases significantly with age over 65 years. This article provides an overview of burden of neurological diseases in Canada to set the stage for the in-depth systematic reviews of the 14 priority neurological conditions presented in subsequent articles in this issue.

More than 600 human disorders afflict the nervous system. Of these, neurodegenerative diseases are usually characterised by onset in late adulthood, progressive clinical course, and neuronal loss with regional specificity in the central nervous system. They include Alzheimer's disease and other less frequent dementias, brain cancer, degenerative nerve diseases, encephalitis, epilepsy, genetic brain disorders, head and brain malformations, hydrocephalus, stroke, Parkinson's disease, multiple sclerosis, amyotrophic lateral sclerosis (ALS or Lou Gehrig's Disease), Huntington's disease, and Prion diseases, among others. Neurodegeneration usually affects, but is not limited to, the cerebral cortex, intracranial white matter, basal ganglia, thalamus, hypothalamus, brain stem, and cerebellum. Although the majority of neurodegenerative diseases are sporadic, Mendelian inheritance is well documented. Intriguingly, the clinical presentations and neuropathological findings in inherited neurodegenerative forms are often indistinguishable from those of sporadic cases, suggesting that converging genomic signatures and pathophysiologic mechanisms underlie both hereditary and sporadic neurodegenerative diseases. Unfortunately, effective therapies for these diseases are scarce to non-existent. In this chapter, we highlight the clinical and genetic features associated with the rare inherited forms of neurodegenerative diseases, including ataxias, multiple system atrophy, spastic paraplegias, Parkinson's disease, dementias, motor neuron diseases, and rare metabolic disorders.

Ralstonia species are Gram-negative bacilli that have increasingly been recognized as emerging nosocomial pathogens, particularly in immunocompromised hosts. Ralstonia pickettii is the most clinically important pathogen from the Ralstonia genus. Nosocomial outbreaks of Ralstonia pickettii infections brought about by the use of contaminated medical solutions, including saline, sterile water, as well as disinfectants, have been reported. There have been case reports of invasive infections with variable presentations. Here, we describe three cases of Ralstonia pickettii bacteremia during a period of one year in a tertiary care hospital in Karachi, Pakistan. The first case was a 76-year-old male, known case of type 2 diabetes mellitus (DM), hypertension, and amyotrophic lateral sclerosis, who presented with complaints of burning micturition, hematuria, and fever. The patient had a history of multiple hospital admissions in the recent past. His blood culture was found to be positive for Ralstonia pickettii. A computed tomography scan of the kidneys, ureter, and bladder (CT KUB) was suggestive of pyelonephritis. The patient improved on intravenous meropenem. The second case was a 47-year-old man, who was admitted with a gunshot injury to the neck, resulting in complete cervical cord resection and mild hydrocephalus with intraventricular hemorrhage. The patient had a prolonged intensive care unit (ICU) stay, which was complicated by ventilator-associated pneumonia with Acinetobacter and central line-associated bloodstream infection (CLABSI) with Ralstonia pickettii. He was treated with meropenem and colistin but continued to deteriorate and expired. The third case was a 46-year-old lady, known case of end-stage renal disease (ESRD), who was admitted with prosthetic valve endocarditis. She had a prolonged hospital stay complicated by CLABSI with Ralstonia pickettii, improved on meropenem, but later died due to fungemia. Ralstonia pickettii is an emerging cause of nosocomial infection in patients, particularly those with a prolonged hospital stay, and can cause invasive and severe infections.

Electrical injury can affect any system and organ. Central nervous system (CNS) complications are especially well recognised, causing an increased risk of morbidity, while peripheral nervous system (PNS) complications, neurourological and cognitive and psychological abnormalities are less predictable after electrical injuries. PubMed was searched for English language clinical observational, retrospective, review and case studies published in the last 30 years using the key words: electrical injury, electrocution, complications, sequelae, neurological, cognitive, psychological, urological, neuropsychological, neurourological, neurogenic, and bladder. In this review, the broad spectrum of neurological, cognitive, psychological and neurourological consequences of electrical trauma are discussed, and clinical features characteristic of an underlying neurological, psychological or neurourological disorder are identified. The latest information about the most recently discovered forms of nervous system disorders secondary to electrical trauma, such as the presentation of neurological sequelae years after electrocution, in other words long-term sequelae, are presented. Unexpected central nervous system or muscular complications such as hydrocephalus, brain venous thrombosis, and amyotrophic lateral sclerosis are described. Common and uncommon neuropsychological syndromes after electrical trauma are defined. Neurourological sequelae secondary to spinal cord or brain trauma or as independent consequences of electrical shock are also highlighted.
