A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample-matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced, and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis.

Spinal reflexes and the concentrations of 5-HIAA, MHPG, and HVA in lumbar cereborspinal fluid after spinal lesions in man. (1/259)

Descending bulbospinal pathways that employ specific neurotransmitter substances are known to be capable of modulating segmental reflex activity in the experimental animal. To determine whether this might also occur in man correlations have been sought between the activity in spinal reflex pathways and the lumbar cerebrospinal fluid (CSF) concentrations of 5-hydroxyindolacetic acid (5-HIAA), 3 methoxy-4-hydroxyphenylglycol (MHPG), and homovanillic acid (HVA) in 12 patients with complete or virtually complete spinal lesions. The concentrations of 5-HIAA and MHPG in lumbar CSF ARE REDUCED AFTER COMPLETE OR VIRTUALLY COMPLETE SPINAL LESIONS IN MAN. This may occur within 18 days of the lesion. MHPG concentrations appear to be inversely related to the level of the lesion. The HVA concentration in lumbar CSF is reduced when there is obstruction of the CSF pathways. No relationship could be demonstrated between the concentrations of 5-HIAA or MHPG in lumbar CSF and the activity in the spinal monosynaptic pathway (estimated from the proportion of the motoneurone pool activated by the Achilles tendon reflex or H reflex) or the activity of a spinal inhibitory mechanism (estimated by the degree of vibratory inhibition of the monosynaptic reflex). Patients with a tonic vibration reflex (TVR) tended to have higher MHPG levels. There appeared to be an association between low CSF HVA and enhanced vibratory inhibition of the monosynaptic reflex in the nine patients whose spinal lesions were complete.  (+info)

Endogenous proteins controlling amyloid beta-peptide polymerization. Possible implications for beta-amyloid formation in the central nervous system and in peripheral tissues. (3/259)

We report that certain plasma proteins, at physiological concentrations, are potent inhibitors of amyloid beta-peptide (Abeta) polymerization. These proteins are also present in cerebrospinal fluid, but at low concentrations having little or no effect on Abeta. Thirteen proteins representing more than 90% of the protein content in plasma and cerebrospinal fluid were studied. Quantitatively, albumin was the most important protein, representing 60% of the total amyloid inhibitory activity, followed by alpha1-antitrypsin and immunoglobulins A and G. Albumin suppressed amyloid formation by binding to the oligomeric or polymeric Abeta, blocking a further addition of peptide. This effect was also observed when the incorporation of labeled Abeta into genuine beta-amyloid in tissue section was studied. The Abeta and the anti-diabetic drug tolbutamide apparently bind to the same site on albumin. Tolbutamide displaces Abeta from albumin, increasing its free concentration and enhancing amyloid formation. The present results suggest that several endogenous proteins are negative regulators of amyloid formation. Plasma contains at least 300 times more amyloid inhibitory activity than cerebrospinal fluid. These findings may provide one explanation as to why beta-amyloid deposits are not found in peripheral tissues but are only found in the central nervous system. Moreover, the data suggest that some drugs that display an affinity for albumin may enhance beta-amyloid formation and promote the development of Alzheimer's disease.  (+info)

Quinupristin/dalfopristin attenuates the inflammatory response and reduces the concentration of neuron-specific enolase in the cerebrospinal fluid of rabbits with experimental Streptococcus pneumoniae meningitis. (4/259)

The inflammatory response following initiation of antibiotic therapy and parameters of neuronal damage were compared during intravenous treatment with quinupristin/dalfopristin (100 mg/kg as either a short or a continuous infusion) and ceftriaxone (10 mg/kg/h) in a rabbit model of Streptococcus pneumoniae meningitis. With both modes of administration, quinupristin/dalfopristin was less bactericidal than ceftriaxone. However, the concentration of proinflammatory cell wall components (lipoteichoic acid (LTA) and teichoic acid (TA)) and the activity of tumour necrosis factor (TNF) in cerebrospinal fluid (CSF) were significantly lower in the two quinupristin/dalfopristin groups than in ceftriaxone-treated rabbits. The median LTA/TA concentrations (25th/75th percentiles) were as follows: (i) 14 h after infection: 133 (72/155) ng/mL for continuous infusion of quinupristin/dalfopristin and 193 (91/308) ng/mL for short duration infusion, compared with 455 (274/2042) ng/mL for ceftriaxone (P = 0.002 and 0.02 respectively); (ii) 17 h after infection: 116 (60/368) ng/mL for continuous infusion of quinupristin/dalfopristin and 117 (41/247) ng/mL for short duration infusion, compared with 694 (156/2173) ng/mL for ceftriaxone (P = 0.04 and 0.03 respectively). Fourteen hours after infection the median TNF activity (25th/75th percentiles) was 0.2 (0.1/1.9) U/mL for continuous infusion of quinupristin/dalfopristin and 0.1 (0.01/3.5) U/mL for short duration infusion, compared with 30 (4.6/180) U/mL for ceftriaxone (P = 0.02 for each comparison); 17 h after infection the TNF activity was 2.8 (0.2/11) U/mL (continuous infusion of quinupristin/dalfopristin) and 0.1 (0.04/6.1) U/mL (short duration infusion), compared with 48.6 (18/169) U/mL for ceftriaxone (P = 0.002 and 0.001). The concentration of neuron-specific enolase (NSE) 24 h after infection was significantly lower in animals treated with quinupristin/dalfopristin: 4.6 (3.3/5.7) microg/L (continuous infusion) and 3.6 (2.9/4.7) microg/L (short duration infusion) than in those treated with ceftriaxone (17.7 (8.8/78.2) microg/L) (P = 0.03 and 0.009 respectively). In conclusion, antibiotic treatment with quinupristin/dalfopristin attenuated the inflammatory response within the subarachnoid space after initiation of antibiotic therapy. The concentration of NSE in the CSF, taken as a measure of neuronal damage, was lower in quinupristin/dalfopristin-treated rabbits than in ceftriaxone-treated rabbits.  (+info)

A 20-year epidemiological study of pneumococcal meningitis. (5/259)

We conducted a retrospective analysis of 55 community-acquired Streptococcus pneumoniae meningitis illnesses in Huntington, West Virginia, from 1978 to 1997. Fourteen (36.8%) of 38 adults and 2 (11.8%) of 17 children died. Serotypes 6, 23, 3, and 18 accounted for 20 (41.7%) of 48 strains available for serotyping. Of 40 strains available for antimicrobial susceptibility testing, 1 serotype 19 and 1 serotype 23 strain showed intermediate resistance and a second serotype 23 strain showed high resistance to penicillin; all three patients survived. The case-fatality rates among adults who received penicillin alone, gentamicin in combination, or vancomycin and cephalosporin together were 57.1%, 55.5%, and 60%, respectively, and among those who received chloramphenicol or a third-generation cephalosporin, they were 11.1% or nil, respectively. No child died who received chloramphenicol or vancomycin. Two (33%) of 6 children died who received a third-generation cephalosporin; both were critically ill when initially treated. No child and one adult had received pneumococcal vaccine prior to becoming ill.  (+info)

High sensitivity and specificity of serum procalcitonin levels in adults with bacterial meningitis. (6/259)

It was shown in children that serum procalcitonin was the best marker to use to differentiate bacterial from viral meningitis. To evaluate procalcitonin in the diagnosis of acute bacterial and viral meningitis, we conducted a prospective study including adult patients who were suspected of having meningitis and who were admitted to an emergency department. Cerebrospinal fluid (CSF) and serum levels of procalcitonin were measured in 105 consecutive patients. The diagnosis of meningitis was based on clinical findings, gram staining, culture, and chemical analysis of CSF. Twenty-three patients had bacterial meningitis, 57 had viral meningitis, and 25 did not have meningitis. Bacteriologic and chemical analysis of CSF did not allow correct differentiation of viral from bacterial meningitis. On the other hand, a serum procalcitonin level >0.2 ng/mL had a sensitivity and specificity of up to 100% in the diagnosis of bacterial meningitis. Serum procalcitonin levels seem to be the best marker in differentiating between bacterial and viral meningitis in adults.  (+info)

HLA-DPB1*0501-associated opticospinal multiple sclerosis: clinical, neuroimaging and immunogenetic studies. (7/259)

In order to clarify the relationship between the clinical phenotype and the human leucocyte antigen (HLA) in multiple sclerosis in Asians, 93 Japanese patients with clinically definite multiple sclerosis underwent clinical MRI and HLA-DPB1 gene typing studies. According to a neurological examination, 29 patients were classified as opticospinal multiple sclerosis, 17 as spinal multiple sclerosis and 47 as Western type multiple sclerosis showing the involvement of multiple sites in the CNS including either the cerebrum, cerebellum or brainstem. The opticospinal multiple sclerosis showed a significantly higher age of onset, higher expanded disability status scale scores and higher CSF cell counts and protein content than the Western type multiple sclerosis. On brain and spinal cord MRI, the opticospinal multiple sclerosis showed a significantly lower number of brain lesions, but a higher frequency of gadolinium-enhancement of the optic nerve and a higher frequency of spinal cord atrophy than in Western type multiple sclerosis. The frequency of the HLA-DPB1*0501 allele was found to be significantly greater in opticospinal multiple sclerosis (93%) than in healthy controls (63%, corrected P value = 0.0091 and relative risk = 7.9), but not in Western type multiple sclerosis (66%) or spinal multiple sclerosis (82%). The marked differences in the clinical and MRI findings as well as in the immunogenetic backgrounds between the opticospinal multiple sclerosis and Western-type multiple sclerosis together suggest that HLA-DPB1*0501-associated opticospinal multiple sclerosis is a distinct subtype of multiple sclerosis.  (+info)

Peptide mapping of proteins in cerebrospinal fluid utilizing a rapid preparative two-dimensional electrophoretic procedure and matrix-assisted laser desorption/ionization mass spectrometry. (8/259)

A quick two-step procedure involving liquid phase isoelectric focusing in the Rotofor cell in combination with electroelution in the Mini whole cell gel eluter has been used for purification of proteins from human cerebrospinal fluid (CSF). Fractions, each highly enriched in a single protein band and virtually free of other proteins, were selected for characterization by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-TOFMS). Six CSF proteins, transferrin, alpha1-acid-glycoprotein, Zn-alpha2-glycoprotein, apolipoprotein A1, apolipoprotein E and beta-trace were identified by MALDI-TOFMS analysis of the tryptic digests. These results demonstrate that the combination of liquid phase IEF and electroelution is a rapid preparative two-dimensional separation which can provide single proteins of high purity, in yields sufficient for characterization by MALDI-TOFMS. Characterization of such brain-specific proteins in CSF will be useful in the investigation of the pathophysiology of different brain disorders.  (+info)

Classic chronic inflammatory demyelinating polyneuropathy (CIDP) is characterized by the occurrence of symmetrical weakness in both proximal and distal muscles that progressively increases for more than two months (setting this condition apart from the Guillain-Barré syndrome, which is self-limited). The condition is associated with impaired sensation, absent or diminished tendon reflexes, an elevated cerebrospinal fluid protein level, demyelinating nerve-conduction studies, and signs of demyelination in nerve-biopsy specimens. The course can be relapsing or chronic and progressive, the former being much more common in young adults ...

In a normal healthy patient CSF is clear, colorless, and contains only a few cells. It can have up to five leukocytes per cmm but should not have any erythrocytes present. The leukocytes most often seen are lymphocytes and monocytes. Because the brain requires proteins and glucose for nourishment it is normal to find these molecules in CSF. A normal sample of CSF has a total protein level around 15-45 mg/mL and a glucose level around 40-70 mg/mL. These values can change in response to a disruption in the blood-brain barrier. There are several instances where CSF protein levels will be increased. Mild increases can occur due to inflammation caused by diseases such as meningitis, encephalitis, presence of tumors, hemorrhage, and stroke. Bacterial meningitis will cause a much larger increase in CSF protein concentration. Severe increases in protein concentration can be found in patients with Guillain-Barre syndrome. For patients with multiple sclerosis the increase in protein concentration is mild ...
Cerebrospinal fluid (CSF) protein analysis is an important element in the diagnostic chain for various central nervous system (CNS) pathologies. Among multiple existing approaches to interpreting measured protein levels, the Reiber diagram is particularly robust with respect to physiologic inter-individual variability, as it uses multiple subject-specific anchoring values. Beyond reliable identification of abnormal protein levels, the Reiber diagram has the potential to elucidate their pathophysiologic origin. In particular, both reduction of CSF drainage from the cranio-spinal space as well as blood-CNS barrier dysfunction have been suggested ρas possible causes of increased concentration of blood-derived proteins. However, there is disagreement on which of the two is the true cause.. Methods ...
Values of Magnetic Resonance Imaging and Cerebrospinal fluid analysis in the diagnosis of Central NervousSystem associated infectious diseases
Inflammation is becoming increasingly recognized as an important contributor to Alzheimers disease (AD) pathogenesis. As a part of the innate immune system, the complement cascade enhances the bodys ability to destroy and remove pathogens and has recently been shown to influence Alzheimers associated amyloid and tau pathology. However, little is known in humans about the effects of the complement system and genetic modifiers of AD risk like the ε4 allele of apolioprotein E (APOE ε4) on AD pathobiology. We evaluated cerebrospinal fluid (CSF) protein levels from 267 individuals clinically diagnosed as cognitively normal, mild cognitive impairment, and AD. Using linear models, we assessed the relationship between APOE ε4 genotype, CSF Complement 3 (C3), CSF amyloid-β (amyloid) and CSF hyperphosphorylated tau (ptau). We found a significant interaction between APOE ε4 and CSF C3 on both CSF amyloid and CSF ptau. We also found that CSF C3 is only associated with CSF ptau after accounting for CSF

We performed two independent studies, discovery and validation, to identify AD markers by profiling proteins in human plasma using the aptamer-based SOMAscanTM technology. Specifically, we aimed to identify markers with better performance than the best-performing CSF markers, tau and Ab42, to discriminate AD from non-demented controls. We constructed a 5-protein classifier in the discovery study and demonstrated that the plasma protein classifier allowed the prediction of AD with 100.0% sensitivity, 80.0% specificity, and 90.0% accuracy in an independent validation study, matching or outperforming CSF tau and Ab42. Individual-matched plasma and CSF samples were obtained at the same visit, allowing direct comparison of diagnostic performance between the plasma protein classifier and CSF protein biomarkers. Moreover, the classifier also correctly predicted mild cognitive impairment (MCI), an early pre-dementia state of the disease, with 96.7% sensitivity, 80.0% specificity, and 92.5% accuracy. ...

Guillain-Barré syndrome (GBS) is characterised by a classical triad of progressive motor weakness, areflexia and elevated cerebrospinal fluid (CSF) protein without pleocytosis.1 Landry published the first modern description of an illness likely to be acute inflammatory demyelinating polyneuropathy (AIDP) in 1859. Osler provided a more detailed account of what he called acute febrile polyneuritis in 1892. In 1916, Guillain, Barré and Strohl further enlarged the clinical description and first reported the characteristic CSF finding, albuminocytological dissociation (that is, elevation of CSF protein with normal CSF cell count).1. We consider the pathophysiology, diagnostic features, assessment, differential diagnoses and management of GBS. This article will also outline the spectrum of the disease. Most of the research on GBS has been based on adult or predominantly adult studies, so there has been unavoidable extrapolation with respect to GBS in children and young people ...
ABSTRACT: Tuberculosis (TB) carries a high morbidity and mortality, however, its diagnosis can be difficult due to low concentration of bacteria in the cerebrospinal fluid (CSF). Although increased CSF protein, decreased CSF glucose; cerebrospinal fluid (CSF) pleocytosis with mononuclear cells predominance are commonly used to diagnose TB infection, they show inconsistent results. Objectives: To analyze the relationship between several characteristics of the CSF and TB meningitis. Methods: This is an observational research, with a cross sectional design, 27 patients with TB meningitis and or meningoencephalitis with Thwaites diagnostic score ≤ 4 obtained from mecidal records.

Preterm neonates are at risk for intraventricular hemorrhage (IVH) and subsequent post-hemorrhagic hydrocephalus (PHH). A well-accepted interventional therapy for PHH is ventricular tap (VT). Permanent treatment, ventriculo peritoneal shunt surgery (VPS) is required in the case of some neonates under some conditions (weight, immunological status, CSF protein level) who receive multiple interventions. The objective of this study was to apply a 3D ultrasound system clinically to determine CSF volume within the ventricle, to guide the neurosurgeon regarding the amount of CSF should be removed during every intervention, which lateral ventricle is better to intervene and to predict the possibilities of the requirement of the shunt. After ethics approval and parental consent, this 3D US system was used in a clinical study where data of 70 neonates having IVH were analyzed retrospectively and 22 preterm neonates were recruited prospectively. 3D US system was used to measure the ventricle volume of the neonates
Objectives: The effect of delayed analysis on cerebrospinal fluid (CSF) white blood cell (WBC) count and glucose has never been studied in neonates.. Design: Prospective cohort study.. Setting: Level III newborn unit.. Patients: Neonates undergoing lumbar puncture were enrolled after consent. CSF was analysed at baseline (30 minutes) for protein, WBC and glucose; and from the same sample for WBC and glucose after a lag of 2 h and 4 h after lumbar puncture. Those with traumatic/inadequate CSF were excluded. Subjects were classified in three groups (n = 20 each) based on baseline WBC count: no WBC, 1-30 WBC and ,30 WBC/μl. Analysis was by repeated-measures ANOVA.. Results: There was a significant decline in mean (SD) CSF glucose from baseline to 2 h and 4 h (41.0 (19) to 38.3 (19) and 36.2 (20) mg/dl, respectively) and WBC count (36 (45) to 28.6 (38) and 23.8 (34) cells/μl, respectively; both p,0.001). CSF glucose and WBC declined in all three groups (p,0.001). High baseline CSF WBC (p,0.001) ...

N2 - Introduction We aimed to investigate factors defining amyloid β (1-42) (Aβ1-42) adsorption during preanalytical workup of cerebrospinal fluid (CSF). Methods CSF was transferred to new tubes ≤4 times. Variables tested were different polypropylene tube brands, volumes, CSF Aβ1-42 concentrations, incubation times, pipettes, vortex intensities, and other CSF proteins, including hyperphosphorylated tau and Interleukin 1 Receptor Accessory Protein (IL-1RAcP). An enquiry assessed the number of transfers in current practice. Results In diagnostic practice, the number of transfers varied between 1 and 3. Every tube transfer ...
OBJECTIVES. Isoelectric focusing (IEF) is a laboratory technique that allows to separate proteic molecules based on their isoelectric point. This technique, applied to cerebro spinal fluid (CSF) IgG, has been used to study human neurological diseases. CSF IgG concentration increases either with neurological diseases that alter the blood-brain barrier (BBB), increasing IgG access from the blood, or with neurological diseases that determine local activation of the immune system with intrathecal synthesis (IS) of IgG. To date, no studies on IEF of canine CSF have been performed. The purpose of this study was to investigate IgG patterns of distribution in CSF of dogs with several neurological diseases and to compare these data to CSF total protein concentrations for each dog.. MATERIALS. Twenty-four dogs have been included in the study. Sixteen dogs had spinal cord compression (SCC), 3 dogs had brain neoplasia (BN), 2 dogs had cerebellar abiotrophy (CA), 1 dog had steroid-responsive meningitis ...

Cerebrospinal fluid (CSF) analysis is commonly referred to as a spinal tap. During this procedure, a small volume of spinal fluid is collected and submitted to a laboratory for analysis of protein content, white blood cell count and determination of the types of white blood cells that are present. Spinal fluid is very sensitive for identifying disease in the central nervous system, but is not very specific to which disease is present as there is a great deal of overlap between diseases.. CSF analysis is used in conjunction with other tests, including MRI, to narrow the list of possible neurological diseases. In some cases, CSF will provide a definitive diagnosis, such as lymphoma, a type of cancer. Tests for several infectious diseases (Figure 2) can be performed on spinal fluid if needed.. In animals this procedure is performed under general anesthesia. While a person may be asked to lie still for a procedure, an animal cannot. However, since the animals are under anesthesia, there is no pain ...

A 51-year-old presented with subacute headache, right facial weakness and numbness. MRIB showed widespread enhancing hemispheric lesions with a focal lesion of the right CN VII nucleus. CSF protein 0.84 g/l; CSF lymphs 10×106/l. A diagnosis of ADEM was made and symptoms resolved soon after steroids. Five months later, he developed a progressively ataxic gait, leg weakness and dysarthria. Second CSF showed 12×106/l lymphs and protein of 0.95 g/l. CSF cytology showed nonspecific, active, chronic inflammation. MRIB revealed minimally enhancing lesions within the internal capsules, lentiform nuclei extending into the cerebral peduncles. Notably, the CN VII nuclear lesion completely disappeared. MRS suggested an infiltrative process and a diagnosis of grade 2 astrocytoma was made following brain biopsy. It has been proposed that dexamethasone modifies disruptions to the BBB and previous authors report resolution of radiological enhancement in glioma following steroids. We found two cases of high ...

CSF analysis is an important diagnostic tool in the investigation of neurological patients, but there are limitations to it. The cell count and protein level of the CSF can be thought of as a CNS analogue of the CBC and serum protein level. Abnormalities in the colour, cellularity and protein level of the CSF are strongly indicative of neurological disease and often contribute to the diagnosis, but are non-specific and only occasionally provide a definitive diagnosis by themselves. CNS diseases also do not always cause alterations in the CSF - abnormalities depend on the location and extent of the lesion. Prior treatment with corticosteroids may interfere with CSF and reduce the white blood cell count and percentage of neutrophils. CSF should ideally be processed (or preserved) within 30 minutes after collection because the cells deteriorate rapidly due to little protein content.. CSF collection should be performed prior to myelography, since contrast agents may induce meningeal irritation and ...

Cra binding to the icd promoter region.The binding affinity of the active Cra factor for the icdpromoter region was measured by the EMSA (10). The radiolabeled 328-bp DNA fragment carrying both icd P1 andicd P2 was incubated with increasing concentrations of Cra, and the corresponding complexes were resolved from free DNA by gel electrophoresis and quantified after autoradiography. At the concentrations of Cra used in these experiments, single stable complexes could be resolved by EMSA (Fig. 4A), which indicated that Cra could interact in a specific manner with one operator site in theicd regulatory region. The bandshift assay was performed at a low concentration of DNA (4 pM) such that the approximate free protein concentration equaled the total protein concentration; thus, at half-maximal saturation, there was ,10-fold molar excess of protein relative to nucleic acid (4). The equilibrium binding constant, Kd, could therefore be derived as the total protein concentration at half-maximal ...

To the Editor: Acute encephalitis/encephalopathy associated with human metapneumovirus (HMPV) has been documented in children (1-3). Recently, Fok et al. (4) described an encephalitis case in an adult but were unable to test cerebrospinal fluid (CSF) for HMPV. Following authors recommendations, we performed diagnostic testing on the CSF of an adult with HMPV-associated encephalitis.. A previously healthy 61-year-old man came to our institution with headache and seizures 5 days after onset of an influenza-like illness. A lumbar puncture on admission revealed pleocytosis (36 cells/µL) and a mononuclear predominance of 98%. Results of magnetic resonance imaging and computed tomography of the head and chest radiography on admission were inconclusive. The patient was treated in the intensive care unit for possible viral and bacterial meningoencephalitis. Although results of routine CSF-workup for infectious causes were unremarkable, total CSF protein level was elevated at 1.39 g/L (reference range ...
An 18-year-old woman presented with a progressively worsening headache, photophobia feverishness and vomiting. Three weeks previously she had returned to the UK from a trip to Peru. At presentation, she had clinical signs of meningism. On admission, blood tests showed a mild lymphopenia, with a normal C reactive protein and white cell count. Chest X-ray and CT of the head were normal. Cerebrospinal fluid (CSF) microscopy was normal. CSF protein and glucose were in the normal range. MRI of the head and cerebral angiography were also normal. Subsequent molecular testing of CSF detected enterovirus RNA by reverse transcriptase PCR. The patients clinical syndrome correlated with her virological diagnosis and no other cause of her symptoms was found. Her symptoms were self-limiting and improved with supportive management. This case illustrates an important example of viral central nervous system infection presenting clinically as meningitis but with normal CSF microscopy.. ...

N2 - Sixteen cases of osteosclerotic myeloma and peripheral neuropathy (SM-PN) were reviewed. The neuropathy resembled chronic inflammatory-demyelinating polyneuropathy with predominantly motor disability, high CSF protein levels, and low motor nerve conduction velocities. Twelve of the 16 patients had detectable levels of monoclonal serum proteins, all with ? light chains, but results of other laboratory studies were usually normal. Most of the patients also had organomegaly, endocrine abnormalities, or both. Treatment of solitary lesions with tumoricidal irradiation usually improved the neuropathy and reversed the nonneurologic abnormalities; chemotherapy for multiple osteosclerotic lesions was less helpful..

BACKGROUND: A neuroinflammatory response is suggested to play an important role in delirium, a common complication in older hospitalized patients. We examined whether hip fracture patients who develop postoperative delirium have a different proteome in cerebrospinal fluid (CSF) prior to surgery. METHODS: Patients (≥ 75 years) were admitted for hip ... read more fracture surgery. CSF was collected during spinal anaesthesia; proteins were separated using gel electrophoresis and identified with mass spectrometry. We compared the proteome of patients with and without postoperative delirium. Findings were validated in an independent, comparable cohort using immuno-assays. RESULTS: In the derivation cohort 53 patients were included, 35.8% developed postoperative delirium. We identified differences in levels of eight CSF proteins between patients with and without subsequent delirium: complement factor C3, contactin-1, fibulin-1 and I-beta-1,3-N-acetylglucosaminyltransferase were significantly lower ...
The study enrolled from October 2009 to March 2011. Median age was 32.5 months; sex distribution was equal. Median duration of symptoms was 18.5 days and time from admission to treatment initiation was 11 days.

The aim of this study is to investigate the long-term effects of the initial spinal cord (SC) involvement in MS patients. In this retrospective, single-center study, 824 patients with definite MS were screened. A total of 348 patients were excluded for ambiguous documentation of the initial relapse, pediatric onset, diagnosis of primary progressive disease, irregular assessments or visits causing doubt on the onset of progression time, and clinical follow-up duration less than 12 months. Eventually, 476 MS patients were included. Data regarding the demographics, initial symptoms, the degree of recovery from the initial relapse, neuroimaging, cerebrospinal fluid analysis, long-term disability, and progression were collected from the medical registry. The mean duration of follow-up was 7.49 ± 5.30 years. The percentage of patients entering the progressive disease course was 23.3 in the whole group. A total of 157 patients (33.0%) had SC involvement during the first clinical relapse. These ...
