Introduction:Suicide is closely linked to the substances use. Therefore it is very important to confirm the factors that affect the possibility of suicidal behavior.Methodology:The survey included 200 respondents; 100 heroin addicts on the substitution program that attempted suicide and 100 opiate addicts who have not attempted suicide. The evaluation included a questionnaire with socio-demographic, hereditary and addiction data, legal problems and then the Minnesota Multiphasic Personality Inventory–MMPI-2.Results:The results showed a statistically significant difference compared to the personality structure, especially pronounced in hypersensitive structures, in relation to the duration of addictive experience and duration of heroin by intravenous route, as well as in relation to the presence of psychotic disorders, drug abuse and suicidal behavior in the family.Conclusion:As risk factors among opiate addicts are indentified interfered biological and psychological factors and the effects of the substances themselves.

There is a need for consumers' education on reliable use of herbal medicines and herbal dietary supplements, in order to improve their awareness of the limits of herbal remedies safety and potential risks of their combination with drugs.

More than 70% of intensive care unit (ICU) patients experience heart rhythm disturbances, and these patients have correspondingly higher mortality rates. Consequently, one of the standards of care in ICUs is continuous electrocardiography monitoring. One of the potentially preventable dysrhythmic events is the occurrence of torsade de pointes ventricular tachycardia in the setting of acquired prolonged QT interval. This type of ventricular tachycardia can be malignant because it often progresses to ventricular fibrillation. Many factors predispose to lengthening of the QT interval, the most important of which are electrolyte abnormalities and the administration of specific medications. In this review, we discuss the pathophysiology of acquired long QT interval, stressing the medication-induced acquired long QT-interval and factors present in ICU patients that promote prolongation of the QT interval. We also propose guidelines to avoid the occurrence of torsade de pointes ventricular tachycardia.

The number of methadone-related deaths (MRDs) during a 10-year period (2002-2011) in the region of Vojvodina, Serbia, was increased. The cases were evaluated according to epidemiological parameters, pathohistological findings, and toxicological screening. The majority of victims were men, aged from 20 to 38. Pathohistologically, the signs of acute focal myocardial damage were present in the heart of victims with drug abuse history shorter than 2 years, while both signs of recent and chronic focal myocardial damage were developed among victims with longer drug abuse history (2-5 years). In postmortem blood samples of 54.84% of victims, methadone was detected in combination with diazepam, both in therapeutic range. Alcohol was absent in most cases. Other detected drugs were antipsychotics and antidepressants in therapeutic concentrations. These findings raise the attention to the concomitant use of methadone and benzodiazepines with the need for further studies to clarify the mechanism of death in such cases.
