[Aim - To investigate the presence of offences in the previous past history of perpetrators of violent acts who have undergone forced medical treatment. Methods - The documentation of all patients released over a 10-year period from the National Institute of Forensic Psychiatry (IMEI) was reviewed. A comparison was drawn between patients who were convicted of any type of offense before the violent act (patients with previous offences-PPO) and those who were not (patients with no previous offences-PNO). Results - Eighty-six (29%) and 208 (71%) patients formed the PPO and PNO groups, respectively. Prior contact with psychiatric services was significantly higher in the PPO group (p=0.038) and this group was also more likely to offend under the influence of a psychoactive substance (p<0.001). Exceptional brutality and other qualifying factors were more frequent in the PNO group (p=0.019). Conclusion - As IMEI is the only forensic institution in Hungary, the picture presented here reflects the situation in the entire country. A recidivism rate of 29% is within the internationally published range. ]

[Lack of associations between CLU and PICALM gene polymorphisms and Alzheimer’s disease in a Turkish population]

SEN Aysu, ARSLAN Mehtap, ERDAL Emin Mehmet, AY Izci Ozlem, YILMAZ Gorucu Senay, KURT Erhan, ARPACI Baki

[Background and purpose - To investigate the association between the rs11136000 single nucleotide polymorphism (SNP) of the clusterin (CLU) gene, the rs541458 and rs3851179 SNPs of the phosphatidylinositol-binding clathrin assembly protein (PICALM) gene and Alzheimer’s disease (AD) in a Turkish population, and to determine whether there are any relationships between the CLU and the PICALM genotypes and behavioral and psychological symptoms of dementia (BPSD) in the Turkish population. Methods - One-hundred and twelve AD patients and 106 controls were included in this study. BPSD were evaluated by the Behavioral Pathology in Alzheimer’s Disease Rating Scale (BEHAVE-AD). SNPs in the CLU and the PICALM gene were genotyped by Real-Time PCR. Genotype distributions were assessed for the groups of patients and controls, for the patient groups with and without each BPSD, and “No BPSD” and “BPSD”. Results - The CLU and the PICALM genotypes were similar in the AD and control subjects, and the groups with and without each BPSD. There were also no significant differences between the “No BPSD” and the “BPSD” groups for the PICALM genotypes, but even without a statistical significance, it is notable that none of the “No BPSD” patients had genotype pattern CLU-rs11136000-TT, and the female subjects with genotype pattern CLU-rs11136000-TT had higher mean score of BEHAVE-AD. Conclusion - This study claims that investigated SNPs are not genetic risk factors for AD in a Turkish population. In addition, the rs541458 and rs3851179 of PICALM SNPs are not related to development of BPSD, but the rs11136000 of CLU SNP might be related to development of BPSD in AD female Turkish subpopulation.]

[Genetic polymorphisms of human beta-defensins in patients with multiple sclerosis]

SZEKERES Márta, SOMOGYVÁRI Ferenc, BENCSIK Krisztina, SZOLNOKI Zoltán, VÉCSEI László, MÁNDI Yvette

[Aims - Recent studies have started to elucidate the contribution of microbiome to the pathogenesis of multiple sclerosis (MS). It is also supposed, that neuropathological alterations might be associated with abnormal expression and regulatory function of antimicrobial peptides (AMPs), including defensins. It is in our interest to investigate the relevance of the single nucleotide polymorphisms (SNPs) of the DEFB1 gene and the copy number polymorphism of the DEFB4 genes in MS. Methods - DEFB1 polymorphisms: c.-20G > A (rs11362), DEFB1 c.-44C > G (rs1800972), DEFB1 c.-52G>A (rs1799946), and the DEFB4 gene copy number were investigated in 250 MS patients The control patients comprised 232 age- and gender-matched healthy blood donors. The occurrence of the human b-defensin 2 peptide (hBD2) in the plasma of controls and patients was determined by ELISA. Results - The DEFB1 c.-44C>G polymorphism the GG protective genotype was much less frequent among patients than among the controls. A higher frequency of a lower (<4) copy number of the DEFB4 gene was observed in the patients with MS as compared with the controls (43% vs. 28%, respectively). The median levels of the circulating hBD2 in the patients were 150.6±12.71 pg/ml vs. 262.1±23.82 pg/ml in the control group (p<0.0001). Our results suggest that b-defensins play role in the development of MS.]

[Proconvulsive effect of antiepileptic drugs]

KELEMEN Anna

[Antiepileptic drugs can provoke and worsen seizures, what is called paradoxical effect. Paradoxical seizure worsening can occur as a nonspecific manifestation of drug intoxication in number of antiepileptic drugs. The other type is a specific type, when antiepileptic drugs with pure GABAergic and sodium channel blocker mechanism of action provoke myoclonic, absence and atonic seizures in specific epilepsy syndromes, mainly in idiopathic generalized epilepsies. Antiepileptic drug-induced exacerbation of seizures is a common, often unrecognized clinical problem, which can be avoided by a careful syndromic diagnosis and by using broad spectrum antiepileptic drugs.]

[SUBSTANCE ABUSE AND CARDIOVASCULAR SYSTEM]

VÁLYI Péter

[Substance abuse is an immense problem in Hungary and around the world. Psychological effects of this condition are widely known for abusers and health care workers. Cardiovascular effects of illicit substances are much less well known and can develop as very severe diseases (myocardial infarction, extremely high blood pressure, intracerebral haemorrhage, sudden death etc.) and occur particularly in young people. The treatment of cardiovascular complications of substance abuse may differ from that accepted in non-abusers and some drugs (for example: β-blockers) may be contraindicated. In this review, the effects of substance abuse on the cardiovascular system are discussed, including effects of most commonly abused substances: cocaine, amphetamines, heroin, LSD, marijuana, inhalative substances. In this review the cardiovascular effects of sedato-hypnotics and most widely used substances (alcohol, nicotine, caffeine) are not adressed, since they are well known.]

[The use of ECT for epileptic patient]

FARKAS Márta, BARAN Brigitta, KÁRPÁTI Róbert, RAJNA Péter

[Psychiatric disorders which indicate the use of electroconvulsive therapy (ECT) also occur in epileptic patients, but there is a lack of medical authority concerning the use of ECT in epileptic patients. This is surprising because in recent years it has been proved that ECT has an anti-convulsive effect to some degree. A case study of an epileptic patient is presented whose progress has been monitored for several years. Antiepileptic drugs were seemingly able to control his epilepsy but at the same time progressive behavioural disturbance (schizophreniform psychosis) accompanied by agitation and violent behaviour developed. Considering the recurrent psychotic decompensations and the relative ineffectiveness of antipsychotics, the authors decided to administer ECT. As a result they were able to bring about the longest symptom free balanced period in the patient. According to the data based on previous medical studies and the experience they can suppose that ECT is not immediately contraindicated by the presence of epilepsy with active interictal focus if the psychopathological condition makes it necessary. In view of the epileptogenic risk factors of classical neuroleptics, the epileptogenic effects of accompanying psychosis and the probable anticonvulsive potential of ECT in cases of severe psychiatric complications accompanying epilepsy ECT could be used more frequently.]
