The effect of the synthetic peptide IEW (Neogen) with immunomodulating properties on postradiation recovery of haemopoiesis was investigated. We have shown that Neogen is a potential stimulator of haemopoiesis. The administration of Neogen after irradiation shortened duration of period of the recovery of the compartment of CFU-S-8 and the amount of bone marrow cells. The comparision of the effects of Neogen and GM-CSF (Leucomax) and G-CSF (Granocyte 34) have shown that the targets for these agents are probably different: polypotent CFU-S-for Neogen, and CFU-GM-for GM-CFS. Based on the results, we suggested the mechanism of Neogen effects on heamopoiesis.

Human cytomegalovirus (HCMV) IgM serum antibodies to two nonstructural gene products UL44 and UL57 (p52 and CM2) were assayed in patients with the diagnosis of the chronic fatigue syndrome (CFS) according to criteria established by the US Centers for Disease Control and Prevention. A subset of 16 CFS patients demonstrated HCMV IgG, but no HCMV IgM serum antibodies to conformational structural HCMV antigens (designated, V). By convention, these findings are interpreted to indicate only a remote HCMV infection. However, HCMV IgM p52 and CM2 antibodies were uniquely present in these 16 CFS patients. Other CFS patients with similar HCMV (V) IgG antibodies (18 patients), non-fatigued HCMV (V) IgG-positive control patients (18 patients), random HCMV (V) IgG-positive control patients from a clinical laboratory (26 patients), and non-fatigued HCMV (V) IgG-negative control patients (15 patients) did not have HCMV, IgM p52 or CM2 serum antibodies (p < 0.05). Control HCMV (V) IgG-positive patients had no serum IgM HCMV (V) antibodies to conventional structural HCMV (V) antigen. Thus, 77 various control patients did not contain IgM p52 or CM2 serum antibodies. The presence of IgM p52 and/or CM2 HCMV serum antibodies in this subset of CSF-specific patients may detect incomplete HCMV multiplication in which a part of the HCMV protein-coding content of the HCMV genome is processed, but remains unassembled. These findings suggest that the presence of HCMV IgM p52 and CM2 serum antibodies may be a specific diagnostic test for the diagnosis of a subset of CFS patients. Further, these data suggest an etiologic relationship for HCMV infection in this group of CFS patients.

The lumbar puncture (LP) is a relatively simple diagnostic test. However, significant diagnostic ambiguity can arise when trauma from the needle causes bleeding into the subarachnoid space, especially when trying to make the diagnosis of subarachnoid hemorrhage (SAH). The purpose of this article is to assist emergency physicians in distinguishing traumatic LPs from SAH. To correctly interpret the findings of a traumatic tap, a few concepts must be understood. Timing of the LP in relation to the onset of the SAH affects the results of the cerebrospinal fluid (CFS) analysis; the typical findings will change with time. With a few caveats, xanthochromia, the yellow discoloration of the CSF resulting from hemoglobin catabolism, is often critical in making a diagnosis of SAH. A few of the most essential methods for distinguishing traumatic LP from true SAH include: the "three tube test," opening pressure, and inspection for visual xanthochromia.

Campylobacter fetus subsp. fetus (C. fetus) is a gram-negative, curved, rod-shaped microaerophile, occasionally may cause meningitis or meningoencephalitis in humans. This report documents the case of 49-year-old man with lumbar spondylodiscitis and meningoencephalitis caused by C. fetus infection. On admission, the patient was delirious and severe inflammatory reactions were seen in his serum. Cerebrospinal fluid (CFS) revealed normal glucose concentration and moderate mononuclear leukocytosis. Campylobacter species, which was very difficult to be identified, was cultured from the blood and CSF. During his clinical course, the patient complained of severe back pain, and lumbar MRI showed low intensity in a T1-weighed image of the L4 and L5 vertebral bodies and high intensity in a T2-weighed image of the L4-5 disc. The patient was diagnosed with spondylodiscitis caused by C. fetus infection. Meningoencephalitis may have occurred as a secondary infection. Antibiotics were administered, and the patient's condition improved. To our knowledge, only a few cases of spondylodiscitis caused by C. fetus have been reported. A CSF glucose concentration in the normal range and mononuclear leukocytosis are atypical findings in patients with pyogenic meningitis. Therefore, neurologists must be fully aware of the possible symptoms and signs of C. fetus infection.

The cognitive approach to the treatment of chronic fatigue syndrome (CSF) is based on a multifactor etiological hypothesis, i.e. inaccurate beliefs and attitudes to the illness interact with pathophysiological processes, ineffective coping behaviours, negative states of mood, social problem, to perpetuate the illness. Patients suffering from CFS are supposed to be hypervigilant to somatic sensations and to interpret them as signs of impending physical catastrophe. The aim of the this paper is to describe the clinical implementation of principles of cognitive therapy in the treatment of CFS. Basic to the treatment approach is a collaborative, listening and empathic attitude, sensitive to the patient's personal beliefs and potential threats to self-esteem. The aim is to develop more useful, functional, formulations of the illness. The patient and the therapist work together to look at how the patient thinks about herself/himself and the illness, detect unhelpful attitudes, thoughts and mental images about the illness, and to make them accessible to Socratic reasoning. Graded behavioural interventions are planned in order to disconfirm unhelpful beliefs and reverse the spiral of tiredness, demoralization and reduced activity. The treatment is structured according to the general principles of cognitive therapy.

The Health Council of the Netherlands has issued a report on the chronic fatigue syndrome (CFS). CFS is a real and seriously debilitating condition which imposes limitations on an individual's personal, occupational and social functioning. It is a syndrome of unknown aetiology without physical signs or biological markers. Although there is no disease, patients both feel ill and give the appearance of being ill. There is no consensus on whether CSF patients are able to work or whether they should be entitled to social security benefits. An imbalance between demand and coping is central in CFS, with stress as an important intermediary factor. It is little use concluding that unexplained signs are 'psychological' or that 'I cannot find anything wrong with you so you must be healthy'. The classical view that mind and body are separate systems is outmoded. The bio-psycho-social model of disease may be helpful in describing the interaction between body, mind and circumstance. Putting the CFS patient at ease and explaining the pathophysiology of the symptoms is a useful approach but many patients and patient associations are still very somatically orientated, thereby sustaining the condition. However, in patients who accept that their problems may be stress-induced and are prepared to participate in therapy, some therapies have been proven to be effective, notably cognitive behavioural therapy.

We report a 41-year-old man with meningoencephalitis associated with herpes simplex virus type 1 (HSV-1). The patient developed fever, headache and dysuria followed by generalized convulsion and neck stiffness, and the CSF showed pleocytosis. The titers of enzyme-linked immunosorbent assay against HSV measured 6 days after onset showed a significant rise; IgG antibody 4.89 (<0.2) and IgM antibody 1.45 (<0.8) in CSF, IgG antibody 46.1 (<2.0) and IgM antibody 1.76 (<0.8) in the serum. The antibody index for IgG was 0.50, and that for IgM was 4.2. CFS neutralization test showed HSV-1 antibody of x16 and HSV-2 antibody of <x4. MRI showed atypical features: disseminated cortical lesions without massive hemispheric involvement. All of the cortical lesions were small and appeared to be located in the gray matter. The patient recovered with acyclovir. This report demonstrates that disseminated encephalitis can be a feature of acute HSV-1 infection.

Crow-Fukase syndrome is diagnosed based on the presence of chronic sensori-motor polyneuropathy along with other characteristic generalized symptoms denoted by the acronym of POEMS which stands for polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes. In this syndrome, the serum levels of the vascular endothelial growth factor (VEGF) are abnormally elevated, and this is a predictive factor for its diagnosis. Although the causes of CFS/POEMS remain unknown, VEGF is evidently correlated with its pathogenesis. Human glioblastoma cells are known to express VEGF. In models of CFS/POEMS, mice that are peritoneally transplanted with human glioblastomas exhibit high serum levels of VEGF, prominent edema with increased circulation volume, and pathological findings in the liver, spleen, and kidney. VEGF that is highly concentrated in platelets may be released in massive amounts due to coagulation in the peripheral tissue and may thus exert its maximal physiological effects and produce the abovementioned diffuse pathological findings. The correlation between polyneuropathy and elevated VEGF remains unclear. However, VEGF may affect the blood-nerve barrier by increased microvascular hyperpermeability, upregulated cytokines such as matrix metalloproteases may induce blood-nerve barrier breakdown and demyelination of the peripheral nerve. Furthermore, microangiopathy due to proliferative endothelial cells and hypercoagulated occlusion also affect axonal damage. Novel strategies that have recently been proposed for the management of this disease include high-dose chemotherapy combined with autologous peripheral blood stem cell transplantation (PBSCT) and molecular-targeted therapy against plasma cells and VEGF. Notably, PBSCT exerts a dramatic effect on polyneuropathy; such an effect has rarely been achieved by the previously described modalities of low-dose melphallan and steroid therapy. PBSCT is observed to induce a rapid and persistent decrease in the serum VEGF levels. In conclusion, VEGF is not only the primary molecule involved in the pathogenesis of CSF, but also an important marker for both the diagnosis and treatment of this disease.

The objective was to design a protocol to assess work ability in people suffering ill-defined painful and disabling disorders, the outstanding prototype of which is fibromyalgia/chronic fatigue syndrome (FM/CSF).Following an extensive literature search, the mos appropriate components of current methods of assessment of physical and cognitive abilities were incorporated into the protocol, occasionally with appropriate modification to suit the specific requirements of the individual. The initial part of the assessment consists of a standard history taking, principally focusing on the patient's self-reported physical and cognitive abilities and disabilities, as well as the completion of established pain and fatigue scales, and relevant disability questionnaires. Following this, physical and cognitive abilities are objectively assessed on two separate occasions, utilizing computerized hand-held dynamometers, inclinometers, algometers, and force dynamometers. Specific work simulation tests using the industrial standards Methods-Time-Measurement testing are availed of, as is aerobic testing using the Canadian Aerobic Fitness Test (CAFT). Objective computerised neuro-cognitive testing are also utilised as an integral component of the assessment. All results are then subject to specific computerized analysis and compared to normative and standardised work-based databases. The designed system produces reliable, consistent and reproducible results. It also proves capable of detecting any inconsistencies in patient input and results, in addition to being independent of any possible assessor bias. A new protocol has been designed to determine the working capability of individuals who suffer from various chronic disabling conditions, and represents a significant step forward in a difficult but rapidly expanding area of medical practice.

Chronic fatigue syndrome (CFS) is a disabling condition characterized by unexplained chronic fatigue that impairs normal activities. Although immunological and psychological aspects are present, symptoms related to skeletal muscles, such as muscle soreness, fatigability and increased lactate accumulation, are prominent in CFS patients. In this case-control study, the phenotype of the same biopsy samples was analyzed by determining i) fibre-type proportion using myosin isoforms as fibre type molecular marker and gel electrophoresis as a tool to separate and quantify myosin isoforms, and ii) contractile properties of manually dissected, chemically made permeable and calcium-activated single muscle fibres. The results showed that fibre-type proportion was significantly altered in CSF samples, which showed a shift from the slow- to the fast-twitch phenotype. Cross sectional area, force, maximum shortening velocity and calcium sensitivity were not significantly changed in single muscle fibres from CSF samples. Thus, the contractile properties of muscle fibres were preserved but their proportion was changed, with an increase in the more fatigue-prone, energetically expensive fast fibre type. Taken together, these results support the view that muscle tissue is directly involved in the pathogenesis of CSF and it might contribute to the early onset of fatigue typical of the skeletal muscles of CFS patients.
