The evolution of sphenoid sinus meningoencephalocoeles and cerebrospinal fluid (CSF) rhinorrhoea is poorly understood. We present a case demonstrating the gradual evolution of encephalocoeles from both the lateral walls of a previously normal sphenoid sinus in a patient with dural arteriovenous fistula (DAVF), the CSF leak which developed following staged embolisation of the DAVF was managed by an endoscopic endonasal transpterygoid approach. Our findings suggest that over a period of time, chronic elevation of intracranial pressure (ICP) results in gradual erosion of the lateral wall of the sphenoid with development of meningoencephalocoeles and CSF leaks...

INTRODUCTION: Neurodegenerative parkinsonian syndromes have significant clinical and pathological overlap, making early diagnosis difficult. Cerebrospinal fluid (CSF) biomarkers may aid the differentiation of these disorders, but other than α-synuclein and neurofilament light chain protein, which have limited diagnostic power, specific protein biomarkers remain elusive. OBJECTIVES: To study disease mechanisms and identify possible CSF diagnostic biomarkers through discovery proteomics, which discriminate parkinsonian syndromes from healthy controls...

REVIEW
Mélissa Noack, Pierre Miossec
Rheumatoid arthritis (RA) is a chronic inflammatory disease leading to joint destruction. Cytokines play a key role in its pathogenesis. They contribute to the induction and maintenance of inflammation and thus provide therapeutic targets. Many cytokines are involved in RA, and this review focuses on a few critical ones: tumor necrosis factor (TNF), interleukin (IL)-6, IL-1, IL-17, and GM-CSF. TNF and IL-6 are both well-established targets in RA treatment, and new biologic agents are reaching the market. IL-1 represents a more complex cytokine as results in humans do not reach those in animal models...

Specific changes in personality profiles may represent early non-cognitive symptoms of Alzheimer's disease (AD). Evaluating the subject's personality changes may add significant clinical information, as well as help to better understand the interaction between personality change, cognitive decline, and cerebral pathology. With this study we aimed to describe the relationship between personality changes and cerebrospinal fluid (CSF) markers of AD pathology at early clinical stages of the disease. One hundred and ten subjects, of whom 66 cognitively impaired patients (57 with mild cognitive impairment (MCI), and 9 with mild dementia) and 44 healthy controls, had neuropsychological examination as well as lumbar puncture to determine concentrations of CSF biomarkers of AD pathology (amyloid beta1-42 (Aβ1-42), phosphorylated tau (ptau-181), and total-tau (tau))...

BACKGROUND: Pulmonary alveolar proteinosis (PAP) is a rare lung disease characterized by surfactant accumulation, and is caused by disruption of granulocyte/macrophage colony-stimulating factor (GM-CSF) signaling. Abnormalities in CSF2 receptor alpha (CSF2RA) were reported to cause pediatric hereditary PAP. We report here the first case of CSF2RA-mutated, elderly-onset hereditary (h) PAP. CASE PRESENTATION: The patient developed dyspnea on exertion, and was diagnosed with PAP at the age of 77 years, based on findings from chest computed tomography scan and bronchoalveolar lavage...

INTRODUCTION: Hydrocephalus is a complex neurological disorder with a pervasive impact on the central nervous system. Previous work has demonstrated derangements in the biochemical profile of cerebrospinal fluid (CSF) in hydrocephalus, particularly in infants and children, in whom neurodevelopment is progressing in parallel with concomitant neurological injury. The objective of this study was to examine the CSF of children with congenital hydrocephalus (CHC) to gain insight into the pathophysiology of hydrocephalus and identify candidate biomarkers of CHC with potential diagnostic and therapeutic value...

Streptococcus suis is a zoonotic pathogen that can cause severe pathologies such as septicemia and meningitis in its natural porcine host as well as in humans. Establishment of disease requires not only virulence of the infecting strain but also an appropriate metabolic activity of the pathogen in its host environment. However, it is yet largely unknown how the streptococcal metabolism adapts to the different host niches encountered during infection. Our previous isotopologue profiling studies on S. suis grown in porcine blood and cerebrospinal fluid (CSF) revealed conserved activities of central carbon metabolism in both body fluids...

OBJECT: The incidence of cerebrospinal fluid (CSF)-related complications after intradural spinal tumor (IST) surgery is high and reported in up to 18% of patients. However, no efficient way to prevent those complications has been reported so far. Treating these complications may require prolonged bed rest, re-exploration, external lumbar drain, use of antibiotics, and possible precipitation of other complications. To alleviate the risk of CSF-related complications, we prospectively adopted the intraoperative use of autologous fat grafting after IST surgery...

BACKGROUND: Disturbed amyloid precursor protein (APP) processing is considered to be central to the pathogenesis of Alzheimer's disease (AD). The autosomal dominant form of the disease, familial AD (FAD), may serve as a model for the sporadic form of AD. In FAD the diagnosis of AD is reliable and presymptomatic individuals carrying FAD mutations can give valuable insights into the earliest stages of the disease where therapeutic interventions are thought to be the most effective. METHODS: In the current cross-sectional study, products of APP processing (e...

BACKGROUND: Postural changes are related to changes in cerebrospinal fluid (CSF) dynamics. While sitting up leads to a decrease in cranial CSF pressure, it also causes shifts in the craniospinal CSF volume and compliance distribution. We hypothesized that jugular vein collapse in upright posture is a major contributor to these shifts in CSF volume and compliance. METHODS: To test this hypothesis, we implemented a mathematical lumped-parameter model of the CSF system and the relevant parts of the cardiovascular system...
