In addition to its nutritive and protective effects, the basic function of the cerebrospinal fluid space resides in dynamic equilibration of pressure fluctuations caused by volume changes in three compartments contained within the rigid skull cavity: brain tissue, blood and cerebrospinal fluid. An increase in volume in one of them brings about a compliant withdrawal in volume in the other two. The degree of cerebrospinal fluid compliance can be expressed by means of the pressure/volume index which is directly proportional to this compliance. On the other hand an expansion of fluid space which forces the brain to withdraw its tissue, brings about the dilatation of brain ventricles. The degree of their dilatation depends on the effective pressure of cerebrospinal fluid which counteracts with the resistance of brain venous collectors. The blood in the venous network of the brain and cerebral extracellular fluid play a reversible role in cerebral mass restoration and reduction. These facts explain the reason why, from the physical point of view, the brain is considered to represent a viscous and elastic spongious matter. (Ref. 21.)

Cytological examination of cerebrospinal fluid (CSF) has some specifics. In the pre-analytical phase, due to collection into a tube without fixation and hypooncotic nature with rapid cell degradation, processing is required within 2-3 hours. In the subsequent analytical phase it is necessary to take into account the quantitative limit of the sample due to regular parallel cytological processing and non-morphological methods. A regular entry step of cytological examination is the quantification of cellularity. Even oligocellular samples may exhibit severe cytological findings. In the category of inflammatory processes, the cytological diagnosis of purulent meningitis within a few hours has a fundamental influence on prognosis of the disease. Non-purulent inflammations with a broad differential diagnosis are specified not only by cytological images, but also by parallel non-morphological examinations aimed at detecting an infectious agent or autoimmune nature of inflammation. Neoplastic processes in the intermeningeal space generally require immunocytochemical verification. The minimum amount of CSF for immunocytochemical examinations is 3-5 ml. The requirement for these examinations resulting from the baseline assessment may indicate the need for another sample. If the appropriate procedures and interpretations are followed in the context of parallel non-morphological examinations, the cytological examination of MM can contribute significantly to the diagnosis of pathological conditions in CSF spaces.

Diseases of the central nervous system (CNS) mean for the human organism a potentially dangerous situation. An investigation of cerebrospinal fluid (CSF) provides important information about a character of CNS impairment in the decision-making diagnostic and therapeutic algorithm. The authors present a brief overview of available cerebrospinal fluid assays, shortened indication criteria, a recommended algorithm of CSF assessment in different suspected diseases, and a view of the external quality system. The whole portfolio of obtainable CSF methodology is further subdivided according to the adequate choice into the first and inevitable basic routine panel, and following complicated analyses of highly specialized character. The basic panel is considered for standard laboratories, the complete specialized assessment should be provided by a super-consulting laboratory.

This case report presents a 54-year-old Parkinson´s disease patient who underwent a DBS implantation to the subthalamic nuclei bilaterally. Shortly after the operation, the subcutaneous pocket of the generator filled with a liquid. Repeated aspirations did not show any bacterial contamination, and an infection was not found. In the sample, a beta-trace protein was detected that proved the presence of cerebrospinal fluid. A lumbar drain was immediately placed, and a chest compression bandage was fastened for 7 days. After removing the lumbar drain and the compression bandage, no additional liquid was observed, and the wound healed without any other complication. We present an unusual adverse event related to DBS surgery and suggest an effective treatment that has led to uncomplicated healing.

PURPOSE: The lack of reliable diagnostic and/or prognostic biomarkers for multiple sclerosis (MS) is the major obstacle to timely and accurate patient diagnosis in MS patients. To identify new proteins associated with MS we performed a detailed proteomic analysis of cerebrospinal fluid (CSF) of patients newly diagnosed with relapsing-remitting MS (RRMS) and healthy controls. MATERIAL: Reflecting significantly higher prevalence of MS in women we included only women patients and controls in the study. To eliminate a potential effect of therapy on the CSF composition, only the therapy-naïve patients were included. METHODS: Pooled CSF samples were processed in a technical duplicate, and labeled with stable-isotope coded TMT tags. To maximize the proteome coverage, peptide fractionation using 2D-LC preceded mass analysis using Orbitrap Fusion Tribrid Mass Spectrometer. Differential concentration of selected identified proteins between patients and controls was verified using specific antibodies. RESULTS: Of the identified 900 CSF proteins, we found 69 proteins to be differentially abundant between patients and controls. In addition to several proteins identified as differentially abundant in MS patients previously, we observed several linked to MS for the first time, namely eosinophil-derived neurotoxin and Nogo receptor. CONCLUSIONS: Our data confirm differential abundance of several previously proposed protein markers, and provide indirect support for involvement of copper-iron disbalance in MS. Most importantly, we identified two new differentially abundant CSF proteins that seem to be directly connected with myelin loss and axonal damage via TLR2 signaling and Nogo-receptor pathway in women newly diagnosed with RRMS.
