Objective - Benign paroxysmal positional vertigo (BPPV) is the most common cause of recurrent vertigo. Inflammation is a hypothetic etiological factor in BPPV. The aim of this study was to evaluate inflammatory biomarker levels in BPPV patients and compare these with the healthy subjects. Materials and methods - This prospective case-control study was conducted with 114 newly diagnosed BPPV patients and age- and sex- matched 83 healthy subjects. The laboratory investigations included serum hemogram, full biochemistry profiles, vitamin levels, thyroid hormone profiles, high sensitivity C-reactive protein (hsCRP) and erythrocyte sedimentation rate (ESR). Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte to HDL-cholesterol ratio (MHR) values were calculated and compared between the patients and healthy subjects. Results - The mean age was 39.1 ± 12.4 years for patients, and 37.0 ± 11.9 for controls. Vitamin B12, hematocrit (Hct), creatinine, urea, and fT4 values, lymphocyte, total bilirubin, direct bilirubin and indirect bilirubin levels were significantly lower in BPPV patients (p ˂ 0.05), while HDL, SGOT, and ESR values were significantly higher. In the BPPV patients the mean NLR, PLR, and mean platelet volume (MPV) values were significantly higher than in the control subjects. Neutrophil, platelet, monocyte, MHR, and CRP values were similar in both groups (p ˃ 0.05). Conclusion - Our result suggests that NLR, PLR, MPV, ESR, and bilirubin levels should be taken into account as potential biomarkers of BPPV. As they are inexpensive parameters and widely available, they can be used in clinical practice for prediction of BPPV. However, further large-scale studies are required to confirm this relationship.

TEKESIN Aysel, TUNC Abdulkadir, GÜNGEN Dogan Belma, AVCI Nalan, BAKIS Muhammed, PERK Seyma

Objective - The increasing prevalence of dementia over the previous decades has been accompanied by numerous social and economic problems. The importance of exercise in the prevention of dementia coupled with the impact of aspiration pneumonia on the mortality and morbidity of dementia patients cannot be overstated. This study investigates the effects of pulmonary rehabilitation combined with aerobic stretching exercises on the cognitive function, life quality, effort capacity, and level of depression in patients with mild cognitive impairment (MCI) in the early stages of dementia. Methods - Sixty-nine patients with MCI diagnosis were routinely monitored, and six were excluded because they did not attend the follow-up appointments. The remaining 63 patients undertook pulmonary physiotherapy (PPT) and extremity exercises for six months. The mini-mental state examination (MMSE), six-minute walk test (6MWT), Nottingham health profile (NHP), and Beck depression inventory (BDI) scores were evaluated before and after exercise. Results - PPT plus extremity exercises appeared to significantly improve the MMSE scores and increase the 6MWT (p < 0.001) by an average of 25 m. No significant improvement was observed in the BDI and NHP scores. Conclusion - PPT and aerobic exercise positively affected the cognitive ability of MCI patients and improved their walking distance. These results underscore the importance of combining medical treatment with physical rehabilitation at the onset of dementia, a disease which exerts a significantly negative impact on the economy.

[The treatment of advanced Parkinson’s disease]

KLIVÉNYI Péter, VÉCSEI László

[The treatment of Parkinson’s disease depends on the symptoms of the patients and obviously the stage of the disease. Several different approaches can be found in the literature. Based on the published data, in this review we try to summarize the different approaches to the disease stages and theirs’ clinical relevance. Actually, one of the most important issue is the recognition of advanced stage and therefore we reviewed the device-aided therapies. ]

MOLNÁR István, DEÁK Botond Zsolt, HEGYI Gabriella, KOVÁCS Zoltán, KAPÓCS Gábor, SZŐKE Henrik

[Objectives - Our aim was to evaluate the effects of percutaneous neurolysis of lumbal sympathetic ganglions on pain and the resulting changes in quality of life with validated objective and subjective methods. To follow the adverse effects and complications of the procedure. Materials and methods - A prospective, non-randomized, interventional, clinical cohort study under real life conditons was conducted. The time of the observation was 6 months. Palliative neural therapy was performed to reduce the ischemic pain of the affected leg of the patients involved in the study. Prior to treatment and after 35 days, Visual Analogue Scale (VAS) was used to measure the intensity of lower limb pain. The related changes in the quality of life were followed by a general 36-Item Short-Form Health Survey (SF-36) questionnaire. We measured the changes of the patients’ skin temperature and ankle/arm index. The post-treatment results were compared to the pre-treatment results. We compared the results of objective and subjective measures. We followed the side effects and complications of the pain therapy. Each of the examined subjects had obliterative (Fontaine II/b stage) arterial disease of the lower limbs, in which no revascularization intervention was feasible and their ischemic pain was of VAS≥7. Results - Data of 124 patients (69 male, 55 female) could be evaluated. The decrease in intensity of limb pain in the post-treatment period was significant (p=0.001). Quality of life also indicated a significant improvement (p=0.004). Changes in skin temperature and ankle/arm index demonstrated significant improvement (p≤0.005): skin temperature increased from 27.6°C to 31.2°C, the ankle/arm index inceased from 0.67 to 0.83 on average. Changes in objective and subjective measures correlated with each other. No worthening of symptoms, serious adverse events or complications were observed. Conclusion - The chemical denervation of the lumbar sympathetic ganglions with percutaneous application is a minimally invasive intervention, useful in outpatient care, which can be well tolerated by the patient without any significant side effect or complication. Its hyperaemic effect and the pain reduction of the leg can improve the quality of life of the patients.]

Evaluation of symptom severity, functional status and anxiety levels in patients with carpal tunnel syndrome with different electrophysiological stages

SEVINC Gürses Eftal, TEKESIN Aysel, TUNC Abdulkadir

Objective - The aim of this study was to evaluate the relationship between electrophysiological stage, symptom severity, functional status and anxiety levels in patients with idiopathic carpal tunnel syndrome (CTS). Materials and methods - This study included 130 patients in the 25-79 age group who were classified as clinically and electrophysiologically idiopathic carpal tunnel syndrome in our electromyography (EMG) laboratory. Visual Analog Scale (VAS) was used to assess pain during rest and activity. The Boston Carpal Tunnel Scale (BCTS) was used to evaluate symptom severity and functional status. Symptom Severity Scale (SSS) and Functional Capacity Scale (FCS) were assessed separately as a part of BCTS. Beck Anxiety Inventory (BAI) was used for anxiety assessment. Results - A total of 130 patients (25 males and 105 females) were enrolled to this prospective study. The mean age of the patients was 46.95 ± 10.57 years. When the electrophysiological stage was increased, it was found that SSS score and FCS score were increased (p <0.001). No significant correlation was detected between electrophysiological stage and VAS or BAI score. There was a positive correlation between VAS scores and SSS, FCS and BAI scores (p <0.001). Symptom severity and functional status were correlated with anxiety scores (p <0.001). SSS and FCS values of stage III and above patients were significantly higher than Stage I and II CTS patients (p <0.01). Conclusion - In conclusion, our study showed a significant correlation between symptom severity, functional status and anxiety in CTS patients. This can be interpreted as the mental deterioration of individuals with more severe symptoms. On the other hand, additional psychiatric support options should be recommended in cases of moderate findings but anxious symptoms. Electrophysiological findings shouldn’t be sufficient to measure the effect of the disease on the person.

[Neuropsychological rehabilitation following acquired brain injury]

TAMÁS Viktória, KOVÁCS Noémi, TASNÁDI Emese

[Neuropsychological rehabilitation or rehabilitation neuropsychology is a field within applied neuropsychology. It originally diverges from applied clinical and functional neuropsychology, although it could not be entirely differed from them. The unique nature of this area over the complexity is given by its process-controlled and system-approach aspects. In Hungary the number of neurorehabilitation centres and departments requiring neurocognitive rehabilitation has been continually increasing. Nevertheless, the number is still low; accordingly in our country this field is relatively young and isn’t well known. Authors of this review would like to draw attention to the importance of rehabilitation of patients with acquired brain injury and improvement of their quality of life with the theoretical and practical knowledge, as well as the necessity of future alterations and challenges emphasizing the need of a significant change of this narrow domain. ]

[INFLAMMATION AND ATHEROSCLEROSIS]

JAKAB Lajos

[The role of vascular wall inflammation in the pathogenesis of atherosclerosis is becoming increasingly clear. However, the causal relationship between the inflammation and the course of atherosclerosis, which begins in childhood and continues for life, is debated in the literature. The interpretation of the basic pathophysiologial essence of inflammation is also controversial. This paper summarizes the basics and various features of inflammation, the body's defensive and aversive reaction. The “acute phase reaction syndrome” is a general, immediate, non-specific defense reaction of the organism, which is strongly associated with the specific, adaptive immune response. There are inflammatory processes that are chronic from the start. When looking at the main types and functions of the arterial wall proteoglycans, it is clear that they, along with the lipoprotein receptors and HDL cholesterol, are closely connected to the process, course and characteristics of the inflammation. The arterial wall proteoglycans are definitely capable of directly and indirectly influencing the inflammatory process. The issue of a possible target of statin derivatives other than the inhibition of cholesterol biosynthesis has not been resolved. Atherosclerosis may be considered a primarily chronic individual vasculitis syndrome that involves all layers of the blood vessels, and is determined by the risk factors and by the special structure of the arterial wall. The presence of inflammation is a prerequisite to the development and throughout the entire course of atherosclerosis.]

[Inclusion body myositis - a rarely recognized disorder]

DÉZSI Lívia, DANIELSSON Olof, GÁTI István, VARGA Edina, VÉCSEI László

[Inclusion body myositis is the most common disabling inflammatory myopathy in the elderly. It is more frequent in men and after the age of 50 years. Inflammatory and degenerative features coexist. There is a T-cell mediated autoimmunity driven by in situ clonally expanded cytotoxic CD8-positive T-cells invading non-necrotic muscle fibres expressing MHC-I antigen. The hallmarks of degeneration are the deposition of protein aggregates and the formation of vesicles. The course of the disease is slow and the diagnosis is usually set after several years. The muscle weakness and wasting is assymetric, affecting predominantly distal muscles of the upper extremity and proximal muscles of the legs. The signs and clinical course can be characteristic, but the diagnosis is established by muscle biopsy. There is currently no evidence based effective treatment for sIBM. Prednisone, azathioprine, methotrexate, cyclosporine and IFN-β failed. Oxandrolon did not improve symptoms. Treatment with intravenous immunglobuline (IVIG) induced in some patients a transient improvement of swallowing and of muscle strenght, but the overall study results were negative. A T-cell depleting monoclonal antibody (alemtuzumab), in a small uncontrolled study slowed down disease progression for a six-month period. Repeated muscle biopsies showed the reduction of T-cells in the muscle and the suppression of some degeneration associated molecules. An effective therapeutic mean should act on both aspects of the pathomechanism, on the inflammatory and the degenerative processes as well.]

[The role of endothelium, cell migration, chemokines and angiogenesis in inflammatory rheumatic diseases]

BESENYEI Tímea, PÁKOZDI Angéla, VÉGVÁRI Anikó, SZABÓ Zoltán, SZEKANECZ Zoltán

[Endothelial cells, leukocyte-endothelial interactions and angiogenesis are highly involved in the pathogenesis of inflammation and thus in that of inflammatory rheumatic diseases. As this research area is very progressive, one needs to review novel molecular mechanisms and new therapeutic approaches in this respect. Authors review the most important functions of endothelial cells, the process of leukocyte extravasation, tissue infiltration and their cellular and molecular basis. Endothelial cells themselves produce a number of inflammatory mediators including interleukin-1 (IL-1), IL-6, IL-8, chemokines and others. Among cell adhesion molecules, β1 and β3 integrins, as well as E-, L- and P-selectins and their respective ligands have been implicated in leukocyte-endothelial adhesion. In recent years, numerous inflammatory mediators, cytokines, chemokines and proteases have been implicated in angiogenesis and angiostasis. Hypoxia, the vascular endothelial growth factor (VEGF)-angiopoietin system and mechanisms driven by β3 integrins are of major importance during angiogenesis. Significant amount of data have become available of the regulation of cell adhesion, migration and neovascularisation. Adhesion, chemokine and angiogenesis research has important clinical, practical aspects for antirheumatic and anti-cancer therapy. VEGF antagonists, anti-integrin antibodies, chemokine and chemokine receptor inhibitors, as well as thalidomide are currently in the first line of development.]

[Role of activated cells and local inflammatory mechanisms in the development of hypertension]

LELBACH Ádám, KOLLER Ákos

[In the past decades an increasing attention has been paid regarding the possible role of the immune system in the development of hypertension. In vitro and in vivo animal experiments, as well as human studies provided evidence for the role of the innate and adaptive immune systems in the development of hypertension, especially in connection with the perivascular adipose tissue, heart and kidney. Inflammatory mediators, cytokines, reactive oxygen metabolites have not only local pro-hypertensive effecting the vasculature, but also influence the development of hypertension through other regulatory mechanisms, such as the central nervous system. These findings provide a new understanding of the development of hypertension, as well as offer new potential mechanisms that can be targeted with novel the - rapies.]

[DIAGNOSTIC POSSIBILITIES IN HEAD AND NECK MRI]

GŐDÉNY Mária

[Digital cross-sectional imaging techniques, especially computed tomography (CT) and magnetic resonance imaging (MRI) play an important role in the diagnosis of pathologic conditions affecting the head and neck. MRI, because of its superb soft tissue contrast resolution and multiplanar imaging ability gives the most information regarding the origin and the extent of a laesion, intracranial extension, perineural-, as well as bone marrow involvement and play key role in the management of different diseases. Careful observation of the characteristic radiological features usually leads to correct diagnosis, however, some of the lesions are not typical, looking very similar and can be difficult to differentiate from each other. The purpose of the present article is to provide an overview of the most common pathologic conditions examined with MRI.]
