[Holistic approach to cardiovascular prevention]

VÁLYI Péter

[Cardiovascular diseases, primarily the organic manifestations of atherosclerosis, such as coronary artery disease, ischaemic stroke, and peripheral arterial diseases, represent the largest healthcare problem in the developed countries, since the mortality, disability, and need for hospitalisation caused by them constitute a bigger burden than that caused by all other diseases combined. A modern, holistic approach to cardiovascular prevention should consider the complete cardiovascular continuum, including genetic predisposition, social-economicalcultural background, environmental factors, the integrated effect of atherosclerotic risk factors, the inhibition of progression of functional and morphologic damages that have already developed, and, if possible, the promotion of regression. Besides targeting the individual, prevention at the public and social level is also important.]

[Interdisciplinarity, workplace stress, holistic management]

SZABÓ Nóra, SZABÓ Gábor, HEGEDÛS Katalin

[INTRODUCTIONS – The physical and psychological condition of health care professionals dealing with the seriously ill is worse than that of those caring for not seriously ill patients. This may be due to the nurses' dissatisfaction, vital exhaustion, workplace stress, social support and the degree of professional and social adjudication. The aim of the survey is to comparatively investigate two groups dealing with the seriously ill – hospice nurses and nurses caring for elderly patients. Hypothesis: hospice nurses are in a more favourable position than nurses caring for elderly patients in terms of satisfaction, vital exhaustion, social support, the degree of workplace stress and professional and social acknowledgement as well. SUBJECTS AND METHODS – The survey was performed among hospice nurses (N=25) and nurses caring for elderly patients (N=50) using a self-assessment questionnaire. The inventory comprised questions related to demographical, professional and social acknowledgement and questionnaires on satisfaction, vital exhaustion, social support and workplace stress. RESULTS – In terms of social support hospice nurses are clearly in a more favourable position than those caring for elderly patients. Workplace stress is higher among nurses caring for elderly patients than that of hospice nurses thus the adverse effects of workplace stressors will more readily appear among nurses working with the elderly. CONCLUSION – The interdisciplinary approach of hospice, the acceptance and inclusion of professionals from fields other than nursing and medicine into the practical care may promote holistic care and the acceptance and acknowledgement of nurses. The greater social support may reduce the nurses’ degree of workplace stress and thus the adverse consequences of workplace stressors. Therefore in the future interdisciplinarity should be extended, communication between specialties should be encouraged within the care for the elderly and – as a matter of fact – on each level and field of the health care system.]

[The aims and latest results of clinical toxicological analysis]

RÓNA Kálmán

[Almost 80 percent of poison-related deaths are caused by drugs. The overwhelming majority of today's clinical toxicological work is comprised of cases of toxic level drug overdose, drug mixups, adverse effects during therapeutic drug administration, as well as intoxication from drug abuse. A prerequisite of adequate therapy of intoxication is the qualitative and quantitative determination of the compounds causing it. The two elements of systematic toxicological analysis are the screening test and the confirmatory test. The review touches on the toxicologic use of the hyphenated chromatographic-spectroscopic instruments and on the alternative biological matrices. It is known that the effects and toxic side-effects of many drugs show substantial interindividual differences even in the same doses. One of the possible causes of this phenomenon is a genetically determined polymorphic drug metabolism. Some pharmacogenetically determined anomalies in drug administration, particularly enzyme inhibition and induction, are of clinical toxicological importance.]

[Zonisamide: one of the first-line antiepileptic drugs in focal epilepsy ]

JANSZKY József, HORVÁTH Réka, KOMOLY Sámuel

[Chronic administration of antiepileptic drugs without history of unprovoked epileptic seizures are not recommended for epilepsy prophylaxis. Conversely, if the patient suffered the first unprovoked seizure, then the presence of epileptiform discharges on the EEG, focal neurological signs, and the presence of epileptogenic lesion on the MRI are risk factors for a second seizure (such as for the development of epilepsy). Without these risk factors, the chance of a second seizure is about 25-30%, while the presence of these risk factors (for example signs of previous stroke, neurotrauma, or encephalitis on the MRI) can predict >70% seizure recurrence. Thus the International League Against Epilepsy (ILAE) re-defined the term ’epilepsy’ which can be diagnosed even after the first seizure, if the risk of seizure recurrence is high. According to this definition, we can start antiepileptic drug therapy after a single unprovoked seizure. There are four antiepileptic drugs which has the highest evidence (level „A”) as first-line initial monotherapy for treating newly diagnosed epilepsy. These are: carbamazepine, phenytoin, levetiracetam, and zonisamide (ZNS). The present review focuses on the ZNS. Beacuse ZNS can be administrated once a day, it is an optimal drug for maintaining patient’s compliance and for those patients who have a high risk for developing a non-compliance (for example teenagers and young adults). Due to the low interaction potential, ZNS treatment is safe and effective in treating epilepsy of elderly people. ZNS is an ideal drug in epilepsy accompanied by obesity, because ZNS has a weight loss effect, especially in obese patients.]

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.

Simultaneous subdural, subarachnoideal and intracerebral hAemorrhage after rupture of a peripheral middle cerebral artery aneurysm

BÉRES-MOLNÁR Anna Katalin, FOLYOVICH András, SZLOBODA Péter, SZENDREY-KISS Zsolt, BERECZKI Dániel, BAKOS Mária, VÁRALLYAY György, SZABÓ Huba, NYÁRI István

The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.

Symptom profiles and parental bonding in homicidal versus non-violent male schizophrenia patients

HALMAI Tamás, TÉNYI Tamás, GONDA Xénia

Objective - To compare the intensity and the profile of psychotic symptoms and the characteristics of parental bonding of male schizophrenia patients with a history of homicide and those without a history of violent behaviour. Clinical question - We hypothesized more intense psychotic symptoms, especially positive symptoms as signs of a more severe psychopathology in the background of homicidal behaviour. We also hypothesized a more negatively perceived pattern (less Care more Overprotection) of parental bonding in the case of homicidal schizophrenia patients than in non-violent patients and non-violent healthy controls. Method and subjects - Symptom severity and symptom profiles were assessed with the Positive and Negative Syndrome Scale in a group of male schizophrenia patients (n=22) with the history of committed or attempted homicide, and another group (n=19) of male schizophrenia patients without a history of violent behaviour. Care- and Overprotection were assessed using the Parental Bonding Instrument (PBI) in a third group of non-violent healthy controls (n=20), too. Results - Positive, negative and general psychopathology symptoms in the homicidal schizophrenia group were significantly (p<0.005) more severe than in the non-violent schizophrenia group. Non-violent schizophrenia patients scored lower on Care and higher on Overprotection than violent patients and healthy controls. Homicidal schizophrenia patients showed a pattern similar to the one in the healthy control group. Conclusions - It seems imperative to register intense positive psychotic symptoms as predictive markers for later violent behaviour. In the subgroup of male homicidal schizophrenia patients negatively experienced parental bonding does not appear to be major contributing factor to later homicidal behaviour.

[In vitro efficiency of doripenem, a new carbapenem against Gram-negative, aerob, problem bacteria - Prospective, multicentric, Hungarian study]

NAGY Erzsébet, SAQQA Muhammad, SZABÓ Judit, MESTYÁN Gyula, SZIKRA Lenke, KONKOLY Thege Marianne

[INTRODUCTION - Doripenem is a new carbapenem derivative, it’s chemical structure is similar to that of meropenem (substitution of one sulfamoxil-aminomethyl chain for the dimethylcarboxy chain) and has one 1-beta-methyl chain which provides resistance to dyhidropeptidase-I enzyme produced by the human kidney. It has a broad-spectrum of activity against multiresistant Gram-negative bacilli such as ESBL-producing Enterobacteriaceae and non-fermentative Gramnegativ bacilli including some strains of Pseudomonas aeruginosa that are resistant to other carbapenems. In 2010 between February and June a multi-centre comparative study was carried out including 5 Hungarian laboratories to investigate the in vitro activity of doripenem. MATERIAL AND METHODS - 1000 fresh, clinically relevant isolates were included both ESBLproducing and non-producing Enterobacteriaceae strains and resistant and multi-resistant Pseudomonas aeruginosa and Acinetobacter strains. The activity of doripenem and the comparator antibiotics (other carbapenems) were tested by the disc diffusion method. In the case of intermediate resistant strains the MIC of doripenem was also determined by the E-test methodology. RESULTS - All but one isolate belonging to the Enterobacteriaceae (592 isolates) were fully susceptible to doripenem. The only Enterobacter strain which proved to be intermediately susceptible to doripenem by the disc diffusion method was also found to be susceptible showing an MIC of 0.125 μg/ml. In the case of the 163 Pseudomonas aeruginosa and the 121 Acinetobacter spp isolates doripenem was the most active carbapenem compared with imipenem and meropenem (78.6% and 50.5% for doripenem versus 67.5% and 42.0% for imipenem and 68.7% and 30.2% for meropenem, respectively). CONCLUSION - According to our multi-centre study doripenem was highly active against both the ESBL-producing and ESBL-non-producing Enterobacteriaceae strains and against a great part of the Pseudomonas and Acinetobacter isolates often involved in nosocomial infections.]
