ABSTRACT

The etiology of drug addiction, a central nervous system (CNS) disease, is not fully known. This complex problem is believed to be connected with concurrently affecting genetic, psychological and environmental factors. The development of addiction is connected with CNS reinforcement system and dopaminergic neurotransmission. Molecular processes are postulated to be of universal character and allow to presume a similar mechanism of dependence for both ethanol and other substances. Therefore, elements of dopaminergic transmission become excellent candidates for the examination of genetic influence on the development of addiction. A relationship between alcoholic disease and the presence of TaqIA1 and DRD2 alleles permits to initiate another investigation of gene-coding DRD2 dopamine receptor. The latest results indicate the importance of brain-derived neurotrophic factor (BDNF) in the regulation of dopaminergic route. The purpose of this research was to reveal the relationship between the Val66Met BDNF gene polymorphism and dependence of psychoactive agent. The examinations were performed with the Local Research Ethics Committee approval and patient's consent. The study group consisted of 100 patients (88 men and 12 women) aged 18-52 years, qualified for research program according to the International Classification of Diseases, Tenth Revision (ICD-10) requirements, medical examination and detailed questionnaire.

ABSTRACT

CASE REPORT: In the past 5 years at our institution, 12 cases involving the ingestion of chlorpropamide 3-15 g were fatal. We report a 23-year-old woman with an estimated ingestion of chlorpropamide 5-10 g. Initial cardiovascular collapse, attributed to the blockade of potassium channel transport, responded to intensive support including 3 days of cardiac pacing. Urinary excretion of chlorpropamide and hypoglycemia persisted until day 27. The toxic mechanisms and high risk of chlorpropamide are summarized. A fatal therapeutic dose ratio as low as 4:1 has made this antidiabetic agent obsolete.

ABSTRACT

CASE REPORT: Intentional intoxication with natural hallucinogenic substances such as hallucinogenic mushrooms continues to be a major problem in the US and Europe, particularly in the harbor complex of northwest Poland (Pomerania). A case is described of Psilocybe intoxication in an 18-year-old man resulting in Wolff-Parkinson-White syndrome, arrhythmia, and myocardial infarction. The indole concentrations of hallucinogenic mushrooms may predict the risk for adverse central nervous system and cardiac toxicity.
