[Antibacterial therapy: 2000 balance and perspectives]

GRABER Hedvig

[Following a brief history of antibacterial therapy and evaluating the achievements and damages occurred, authors focus on today's problems and the following statements are made: Principles of treatment are clearly defined, however the choice of antibiotics may vary in time and in regions according to the differences in bacterial resistance. Antibacterials of the last decade (III-IV. generation fluoroquinolones, streptogramins, oxazolidinones, new vancomycine analogues) are intended to be effective against multiresistant Gram-positive cocci. Beside bacterial resistance, the most difficult therapeutic problems are the infections in the immunocompromised patients. The role of infection in the pathogenesis of certain diseases, e.g. ventricular/duodenal ulcer and probably atherosclerosis, has only recently been discovered; here new prospects may open for antibacterials. Data of the antibiotic utilization in Hungary show radical changes in the last years. Conclusion: the immense power of antibiotics still has its limits: to conquer bacterial disease successfully the intelligent combination of antibiosis, asepsis and immunization are required. ]

[Molecular mechanisms of cardiac hypertrophy and heart failure]

MIKALA Gábor, PETŐ Mónika, VÁLYI Nagy István, CSÁSZÁR Albert

[In this review, the most important molecular mechanisms leading to cardiac muscle hypertrophy and consequentially to heart failure are detailed. In numerous instances, understanding molecular mechanisms offers the possibility for pharmacotherapeutic intervention. First, trimeric G-proteins and their attached intracellular signaling pathways are introduced, with special emphasis on the pathways elucidated by transgenic animal models. In this area, there are several clinically effective drugs to influence cardiac hypertrophy, including ACE inhibitors, angiotensin receptor antagonists, as well as a- and B-adrenergic receptor blockers. Mitogen activated protein kinases participate later in the hypertrophic cascade. There are ongoing investigations on the potential therapeutic use of lipid-soluble statins these are indirect inhibitors of Ras-farnesylation. Altered cellular Ca2+-homeostasis is fundamental with respect to cardiac muscle hypertrophy and heart failure. The third part of this article investigates the role of the calcium/calmodulin dependent protein phosphatase called calcineurin in these processes. Administration of cyclosporin A or tacrolimus (both are inhibitors of calcineurin) may not be recommended in most forms of cardiac hypertrophy, however, in certain settings they may prove to be valuable therapeutic agents. One of the most serious, not yet properly addressed problem of late stage heart failure is the development of ventricular arrhythmias caused by repolarization abnormalities. Certain mechanisms of this phenomenon are highlighted with a special note on Nat-Cat exchange inhibitors as one of future therapeutic agents of much promise. ]

[The role of MR angiography in the examination of intracranial aneurysms: A comparative study]

P. Nagy Zoltán, BAJZIK Gábor , BOGNER Péter, BERÉNYI Ervin, SZÁSZ Krisztina, KOPA János, REPA Imre

[MR imaging has recently emerged for visual representation of blood vessel structures as well. With MR angiography (MRA), appropriate diagnosis can be established for a number of pathologies involving the arteries and veins. In this report, authors analyse the significance of MR and MRA examinations in the diagnostics of intracranial aneurysms of 87 cases, comparing these procedures with results obtained by digital subtraction angiography (DSA), which is regarded as the gold standard method. In 52 patients where surgical intervention was performed, intraoperative findings were used as control. MR - MR angiographic examination was very sensitive in detecting aneurysms larger than 3 mm (98%), the rate of depicting smaller aneurysms proved to be lower (56%), the overall sensitivity was 79%. MRA is an excellent non invasive diagnostic tool in the examination of intracranial aneurysms. The method can not replace catheter angiography completely but its application is justified and useful in many cases. Occasionally, aneurysms not seen on DSA can be depicted with MR angiography. ]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.

Electrophysiological investigation for autonomic dysfunction in patients with myasthenia gravis: A prospective study

NALBANTOGLU Mecbure, AKALIN Ali Mehmet, GUNDUZ Aysegul, KIZILTAN Meral

Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission. Autonomic dysfunction is not a commonly known association with MG. We conducted this study to evaluate autonomic functions in MG & subgroups and to investigate the effects of acetylcholinesterase inhibitors. This study comprised 30 autoimmune MG patients and 30 healthy volunteers. Autonomic tests including sympathetic skin response (SSR) and R-R interval variation analysis (RRIV) was carried out. The tests were performed two times for patients who were under acetylcholinesterase inhibitors during the current assessment. The RRIV rise during hyperventilation was better (p=0.006) and Valsalva ratio (p=0.039) was lower in control group. The SSR amplitudes were lower thereafter drug intake (p=0.030). As much as time went by after drug administration prolonged SSR latencies were obtained (p=0.043).Valsalva ratio was lower in the AchR antibody negative group (p=0.033). The findings showed that both ocular/generalized MG patients have a subclinical parasympathetic abnormality prominent in the AchR antibody negative group and pyridostigmine has a peripheral sympathetic cholinergic noncumulative effect.

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.

NÉMETH Klára Zsófia, SZÛCS Anna , VITRAI József , JUHÁSZ Dóra , NÉMETH Pál János , HOLLÓ András

We aimed to investigate the association between fluoxetine use and the survival of hospitalised coronavirus disease (COVID-19) pneumonia patients. This retrospective case-control study used data extracted from the medical records of adult patients hospitalised with moderate or severe COVID-19 pneumonia at the Uzsoki Teaching Hospital of the Semmelweis University in Budapest, Hungary between 17 March and 22 April 2021. As a part of standard medical treatment, patients received anti-COVID-19 therapies as favipiravir, remdesivir, baricitinib or a combination of these drugs; and 110 of them received 20 mg fluoxetine capsules once daily as an adjuvant medication. Multivariable logistic regression was used to evaluate the association between fluoxetine use and mortality. For excluding a fluoxetine-selection bias potentially influencing our results, we compared baseline prognostic markers in the two groups treated versus not treated with fluoxetine. Out of the 269 participants, 205 (76.2%) survived and 64 (23.8%) died between days 2 and 28 after hospitalisation. Greater age (OR [95% CI] 1.08 [1.05–1.11], p<0.001), radiographic severity based on chest X-ray (OR [95% CI] 2.03 [1.27–3.25], p=0.003) and higher score of shortened National Early Warning Score (sNEWS) (OR [95% CI] 1.20 [1.01-1.43], p=0.04) were associated with higher mortality. Fluoxetine use was associated with an important (70%) decrease of mortality (OR [95% CI] 0.33 [0.16–0.68], p=0.002) compared to the non-fluoxetine group. Age, gender, LDH, CRP, and D-dimer levels, sNEWS, Chest X-ray score did not show statistical difference between the fluoxetine and non-fluoxetine groups supporting the reliability of our finding. Provisional to confirmation in randomised controlled studies, fluoxetine may be a potent treatment increasing the survival for COVID-19 pneumonia.
