[In vitro sensitivity of human anaerobic pathogenic bacteria for tigecycline and comparative antibiotics in Hungary - Prospective multicentre trial]

NAGY Erzsébet, URBÁN Edit, JAKAB Gabriella, SZIKRA Lenke, MISZTI Cecília, SZABÓ Judit

[INTRODUCTION - Tigecycline, the first member of the glycylcycline family of antibiotics, is a semisynthetic derivative of minocycline. The modified tetracycline nucleus is protected against the resistance mechanisms that inactivate tetracyclines, thus tigecycline is expected to be effective against tetracycline- resistant strains. The aim of this multicenter survey, performed in 2007 and 2008 by three Hungarian laboratories, was to examine the efficiency of this drug against antianaerobic bacteria in vitro. MATERIALS AND METHODS - The participating laboratories isolated 540 strains of Gram-positive and Gram-negative anaerobic bacteria from various infectious sites. These sites represent the classes of infections for which tigecycline was recently approved as a treatment option (skin and soft tissue and intra-abdominalinfections), or for which it will be licensed in the near future (lower respiratory tract infections). Evaluation of antibiotic susceptibility was performed by Etest, and the efficiencies of six antibiotics were determined using MIC values. RESULTS - The 540 strains belonged to 33 different species. Of the 104 strains of Gram-positive anaerobic cocci, 100% proved to be susceptible to tigecycline. Similarly, 98% of the examined Clostridium strains showed susceptibility to this antibiotic. Two of the 56 Prevotella strains were resistant against tigecycline. MIC50 and MIC90 values in the 280 Bacteroides strains were 0.5 μg/ml and 1 μg/ml, respectively, whereas only 1.8% of the tested strains showed low resistance. CONCLUSION - Similarly to the findings of international surveys, our results show that tigecycline is effective against the great majority (97.4% susceptibility) of relevant anaerobic bacteria that are isolated from skin and soft tissue, intra-abdominal and lower respiratory tract infections. Thus, empiric use of tigecycline is recommended in any infections where anaerobic bacteria alone or a mixed flora of aerobic and anaerobic bacteria are likely to be present.]

[The majority of patients with advanced Parkinson’s disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinson’s disease; the proportion of Parkinson’s patients with advanced Parkinson’s disease, the referral process, and the clinical features used to characterize advanced Parkinson’s disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinson’s patients identified as advanced patients according to physician’s judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinson’s disease status was assessed with Unified Parkinson’s Disease Rating Scale (UPDRS) parts II, III, IV, and V (modified Hoehn and Yahr staging). Non-motor symptoms were assessed using the PD Non-motor Symptoms Scale (NMSS); quality of life was assessed with the PD 8-item Quality-of-Life Questionnaire (PDQ-8). Parkinson’s disease was classified as advanced versus non-advanced based on physician assessment and on questions developed by the Delphi method. Overall, 2627 patients with Parkinson’s disease from 126 sites were documented. In Hungary, 100 patients with Parkinson’s disease were documented in four movement disorder centers, and, according to the physician assessment, 50% of these patients had advanced Parkinson’s disease. Their mean scores showed significantly higher impairment in those with, versus without advanced Parkinson’s disease: UPDRS II (14.1 vs. 9.2), UPDRS IV Q32 (1.1 vs. 0.0) and Q39 (1.1 vs. 0.5), UPDRS V (2.8 vs. 2.0) and PDQ-8 (29.1 vs. 18.9). Physicians in Hungarian movement disorder centers assessed that half of the Parkinson’s patients had advanced disease, with worse motor and non-motor symptom severity and worse QoL than those without advanced Parkinson’s disease. Despite being classified as eligible for invasive/device-aided treatment, that treatment had not been initiated in 25% of these patients.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

[Clinical neurophysiological methods in diagnosis and treatment of cerebrovascular diseases]

NAGY Ildikó, FABÓ Dániel

[Neurophysiological methods are gaining ground in the diagnosis and therapy of cerebrovascular disease. While the role of the EEG (electroencephalography) in the diagnosis of post-stroke epilepsy is constant, quantitative EEG para-meters, as new indicators of early efficiency after thrombolysis or in prognosis of patient’s condition have proved their effectiveness in several clinical studies. In intensive care units, continuous EEG monitoring of critically ill patients became part of neurointenzive care protocols. SSEP (somatosesnsory evoked potencial) and EEG performed during carotid endarterectomy, are early indicative intraoperativ neuromonitoring methods of poor outcome. Neurorehabilitation is a newly discovered area of neurophysiology. Clinical studies have demonstrated the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of stroke patients. Brain computer interface mark the onset of modern rehabi-litation, where the function deficit is replaced by robotic tehnology. ]

[Complications of infusion treatment with emphasis on extravasation of cytostatics]

HARISI Revekka

[The extravasation of cytostatics is the most signifi cant complication of infusion therapy in cancer treatment. Extravasation refers to the inadvertent infi ltration of cytostatic drugs into subcutaneous or subdermal tissues surrounding the intravenous or intraarterial administration site. According to literature data incidence estimates between 0,01-7%. Extravasated drugs are classifi ed according to their potential for causing damage as vesicant, irritant and nonvesicant. Knowledge of risk factors, the patientrelated and treatment-related ones is important to minimize the occurrence of extravasation. In order to reduce the risk of extravasation, the staff involved in the tumor infusion therapy must be specially trained to implement several preventive and therapeutical protocols. In 2012, ESMO-EONS has put together a new comprehensive treatment protocol on the topic of cytostatics extravasation. Protocol recommended that every oncological department, who administers chemotherapy have to have extravasation trained team and a standby extravasation kit. According to the new ESMO-EONS guideline subcutaneous corticoids are not recommended, anymore. In case of mechloretamine extravasation the recommendation is immediate subcutaneous injection of sodium thiosulfate. After extravasation of anthracyclines, mitomycin C and platin salts the best treatment opportunity is subcutan dimethyl sulfoxide administration. In case of anthracyclines’ extravasation intravenous dexrazoxane treatment is also effective. Hyaluronidase, injected into or under the skin, facilitates absorption of extravasated drugs because of increases connective tissue permeability, promotes the spreading and reduces the local concentration of the extravasated citostatic agents. Hyaluronidase might be effi cacious in preventing skin necrosis by extravasation due to vinca alkaloids. The treatment of unresolved tissue necrosis or pain lasting more than 10 days is surgical debridement. Because of the medical and juristic importance of the extravasation event, it is necessary to establish uniform guidelines for treatment of extravasation, in all Hungarian Oncological Centers.]

VALASEK Tamás, VARGA Péter Pál, KLEMENCSICS István, SZÖVÉRFI Zsolt, BOZSÓDI Árpád, ÉLTES Péter Endre, LAZÁRY Áron

[Background and purpose - The purpose of our study was to outline the Hungarian validation process of the Oswestry Disability Index, the Quebec Back Pain Disability Scale, the Roland-Morris Disability Questionnaire and the Core Outcome Measurement Index, as well as to draw up recommendations regarding their future applications. Methods - The Hungarian versions were brought to life after a cultural and linguistic adaptation. Next to the above-mentioned questionnaires, the questionnaire booklet used for validation also contained the WHOQoL-BREF general quality of life questionnaire and a pain measuring Visual Analog Scale. The data of low-back pain patients were registered twice in two weeks. We determined the internal homogeneity (Cronbach alpha), reproducibility, standard error of measurement and the minimal detectable change of the questionnaires. Patients were assigned into different two subgroups (surgical / non-surgical, with / without affection of nerve roots) and differences between the subgroups were examined with the help of the questionnaires. We determined the physical subscale of the WHOQoL-BREF and the correlation between the pain and the studied questionnaires. Results - The value of Cronbach alpha was between 0.85 and 0.95. All four questionnaires showed significant differences (p<0.001) between the subgroups. The correlation studies brought strong and significant results (p<0.001, r>0.5) in every case. The values of reproducibility were between 0.93-0.92. The results of standard measurement error: 4.8 (Oswestry), 5.2 (Quebec), 1.6 (Roland-Morris), 0.59 (Core Index). The minimal detectable change was 13; 14; 4, and 2 points, respectively. Conclusion - The Hungarian versions of all four questionnaires are valid. They can be applied with scientific certainty to measure low back pain patients. From the studied questionnaires, we especially recommend the wide-raging application of the Oswestry Disability Index and the Core Outcome Measurement Index based on their psychometric and application features. ]
