[50 de novo patients with Parkinson's disease were investigated in a retrospective study after deprenyl monotherapy and a combination of deprenyl and levodopa. The study involved subjects with different Hoehn-Yahr stages. During the treatment period the distribution of age (below or above 60 years) among the Hoehn-Yahr stages was similar to that of the baseline period, while the clinical disability for the patients starting with hypokinesis meant a more severe state compared to the cases with tremor. During the administration of deprenyl, the progression of males was slower than that of females. (-) Deprenyl was effective in decreasing hypokinesis, while rigidity improved less. The reduction of parkinson symptoms developed slowly and was independent of the severity of Parkinson's disease. The maintenance of deprenyl monotherapy showed a high individual variation but the average period was about one year. The termination of the effect of deprenyl was rapid, however, not progressive. The time of the appearance of the side effects of additional levodopa was not delayed by the deprenyl treatment. The reduction of parkinson symptoms by deprenyl and its prolongation of the introduction of levodopa therapy might involve other neurotransmitters than endogenous dopamine.]

[Metoprolol treatment in dialated cardiomyopathy]

DÉKÁNY Miklós, NYOLCAS Noémi, FIÓK János, VÁNDOR László, SEREG Mátyás, BALOGH Ildikó

[Authors applied metoprolol for treating heart failure in with dilated cardiomyopathy. Patients were given digitalis, diuretics as well as ACE-inhibitor and vasodilator drugs. The grade of heart failure was according to NYHA classification in the mean 2.5 class. For assessing the effect of metoprolol clinical variables and results of non-invasive tests were evaluated and compared in 3 consecutive periods: 1) before starting metoprolol, 2) 2–4 weeks after reaching its definitive dose (short-term effect), 3) 3-6 months later (medium-term effect). Early intolerance appeared in 3 patients; signi ficant progression of heart failure in 2 and hypotension causing complaints in 1. Evaluating the actually treated 17 patients clinical signs of heart failure (NYHA class) decreased, left ventricular ejection fraction improved, though not significantly in case of every considered variables, left atrial filling pressure decreased, exercise capacity did not alter, rate-pressure product decreased at rest and at low level of exercise as well. The authors stress the significance of "up-regulation" of myocardial beta-1 receptors in the reduction of myocardial toxic catecholamin effect and myocardial oxygen demand as well as in the increase of myocardial blood supply. Referring to the data of the respective literature and to their own experiences the authors suggest metoprolol treatment in cases of dilated cardiomyopathy, where previus therapy did not prove to be efficient.]

[Role of oxygen derived free radicals during myocardial reperfusion]

KÓNYA László , FEHÉR János, JUHÁSZ Nagy Sándor

[Oxygen derived free radicals are now considered to be important contributors to tissue (myocardium) injury associated with ischemia and reperfusion. Normaly the tissue concentration of these toxic intermediate products of oxygen is strietly limited, but production of oxygen free radicals overwhelming the capacity of the tissue elimination may cause serious damage. Thus reperfusion has it's own danger with the extension of the injury produced by the ischemia alone. Several experi mental studies have shown that different free radical scavengers can reduce the post-ischemic tissue injury, however, there are contradictory results and unresolved problems. Further investigation is necessary to establish the relevance of oxygen free radical mediated myocardial injury and the effective antioxidant treatment. ]

[Autoimmunity and the network of the antibody-forming cells: the "immunological homunculus"]

UHER Ferenc

[Frank M. Burnet's clonal selection theory declares the deletion and/or anergy of self-reactive clones to be the fundamental mechanism responsible for self tolerance. There is ample evidence, however, that all healthy individuals have lymphocytes and , natural” antibodies that recognize self structures. In the 1970s, Niels K. Jerne postulated the network theory. It is based on the idea that the idiotype, the region of an immunoglobulin that is unique because it comprises the antigen-binding portion of the molecule, can act as both antigen and antibody within the same individual. Network theory views the immune system as a single, highly interconnected system, through idiotypes, a web of V domains. Antonio Coutinho adressed this problem and divided the repertoire of the B lymphocytes into two parts. He suggested that a set of naturally activated cells and the immunoglobulins they secrete, is reflected in the autonomous immune activities of the self-related network as the central immune system. In contrast, immune responses to external antigens are essentially allonomous clonal activities of another set of resting, rapidly turning over lymphocytes that follow the predictions of the clonal selection theory, making up the peripheral part of the system. Finally, Irun R. Cohen suggested that some, perhaps all, major autoantigens are indeed dominant because each one of them is encoded in the organizational structure of the immune system. This picture was termed the immunological homunculus by its analogy to the picture of the body encoded in the central nervous system. ]

[Modern therapy of intracerebral and subarachnoidal hemorrhages]


[The frequency of the intracerebral hemorrhages among the strokes is most commonly quoted around 10 percent. The rupture of an intracranial aneurysm is often complicated with subarachnoideal hemorrhage as well as with intracerebral hematoma therefore this latter type of intraparenchymal hemorrhage may also be discussed in this topic. The modern imaging procedures (Computed to mography, Nuclear magnetic resonance) are of crucial importance in the urgent and exact diagnosis of intracranial hemorrhages. The first essential step in the diagnosis of stroke is to distinguish the ischemic lesion from the hemorrhage by means of CT. When an intra cerebral hemorrhage threatens life and the patient's condition is relatively good there must be an urgent decision considering the choice between medical therapy or surgical intervention. Although clearcut indications for surgery are now available, the clinical and computed tomographic guidelines play indi vidually an important role in the final decision. The individual judgment is always desirable in every case of intracerebral hemorrhage as well as in the surgical intrvention of intracranial aneurysm during the acute phase (two days).]

[The microbiology pharmacokinetics and clinical use of carbapenems]

BÁN Éva, PRINZ Gyula

[ Imipenem and meropenem the two currently available carbapenems inhibit the synthesis of the cell wall similarly to other bactericidal B-lactam antimicrobials. These agents have excellent activity against the vast majority of aerobic and anaerobic Gram-positive and Gram-negative organisms. In addition to other B-lactam resistant microbes (e.g. Chlamydia, Mycoplasma) only Stenotrophomonas maltophilia and Enterococcus faecium bacteria are naturally resistant to carbapenems. Carbapenems are extremely stable compounds against nearly all types of B-lactamases: from the penicillinase of Staphylococcus to Class A and Class B types of B-lactamase enzymes of Gram-negative bacteria. Secondary resistance against carbapenems was described in case of the following bacteria: penicilline resistant S. pneumoniae, methicilline resistant Staphylococcus aureus, Pseudomonas aeruginosa, Enterobacter cloaceae, less frequently Enterobacter aerogenes, Serratia mercescens, Klebsiella pneumoniae and Acinetobacter baumannii. The pharmacokinetic profile of imipenem and meropenem are very similar. Carbapenems are valuable as empirical monotherapy due to their broad spectrum of antimicrobial activity and ß lactamase stability in the treatment of severe nosocomial infections, lower respiratory tract or intraabdominal infections and febrile neutropenia. The use of imipenem in central nervous system infection is not approved due to the high incidence of seizures. ]

[The importance of the increase in the use of fix dosage combination of calcium channel blockers in the domestic medical practice between 2007 and 2013]


[Antihipertensive therapy in the complex treatment of diabetes mellitus, obesity and lipid metabolism disorder was discussed, which also means the fight against the emergence of cardiometabolic syndrome and chronic renal failure as well. Angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor antagonists (ARBs), calcium channel blockers (CCB), b-blockers and thiazid diuretics with “A” level of evidence reduce cardiovascular morbidity and mortality. The main effect of CCBs is effective antihipertensive vasodilatation, which is the basis of anti-ischaemic, anti-anginal and antihipertensive agents for use in everyday practice. Based on the database of the National Health Insurance, we analyzed changes in the turnover of CCBs between 2007 and 2013 the examined period among CCBs ordered with TB support amlodipin is the most frequently used active ingredient. In December 2007 almost 75% of the prescriptions was amlodipin. That increased to 87,12% by December 2013. CCBs ordered in monotherapy not changed in the examined period, while combinations increased continuously Among CCBs between 2007 and 2013 the fix dosage combinations available with TB support are: statins (atorvastatin + amlodipin), ACE inhibitors (ramipril + felodipin, lisinopril + amlodipin, perindopril + amlodipin, ramipril + amlodipin, verapamil + trandolapril) and b-blockers (metoprolol + felodipin). Using the assigned CCB monotherapy decreased steadily during the study period, while the use of combination formulations induced gradually increased. At the end of the examined seven year period more than 40% of the prescribed boxes were CCB in fix combination. Use of the combination of amlodipin + perindopril increased while amlodipin + lisinopril continuously reduced. The use of the combination of felodipin + ramipril also decreased.]

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.
