Blunt head injury is a major public health and socioeconomic problem causing death and disability particularly among the young population throughout the world. The purpose of the present study was to evaluate if the impact site is correlated with the subdural and epidural hematoma occurrence. A retrospective analysis of consecutive autopsy cases submitted to our Department during a 5-year period was performed.

Ibogaine is a naturally occurring alkaloid derived from the roots of the rain forest shrub Tabernanthe iboga. Deaths have occurred temporarily related to the use of ibogaine. However, although not licensed as therapeutic drug, and despite evidence that ibogaine may disturb the rhythm of the heart, this alkaloid is currently used as an anti-addiction drug in alternative medicine for detoxification purposes.

A simple and rapid LC/MS method with direct injection analysis was developed and validated for the identification and quantification of ten benzodiazepines (flunitrazepam, nordiazepam, diazepam, 7-aminoflunitrazepam, flurazepam, bromazepam, midazolam, alprazolam, temazepam and oxazepam) in human urine using diazepam-d5 as internal standard (IS). The main advantage of the proposed methodology is the minimal sample preparation procedure, as diluted urine samples were directly injected into LC/MS system. Electrospray ionization in positive mode using selected ion monitoring was chosen for the identification and quantification of the analytes.

Carbon monoxide (CO) is the cause of more than one half of the fatal poisonings throughout the world. The aim of this study was to assess the characteristics of nonfire CO-related deaths in Greece, as they were recorded at the Department of Forensic Medicine and Toxicology, School of Medicine, University of Athens. This retrospective study concerned the toxicological records of all fatal cases of CO poisoning received by the Department of Forensic Medicine and Toxicology during the period 1987 to 2009.

Naphyrone, also known as naphthylpyrovalerone and O-2482, is a cathinone derivative that has been recently advertized for purchase on a number of websites. Naphyrone belongs to a new class of "designer drugs" that has emerged on the drugs abuse market and has gained popularity as the new "legal high." Legal highs have been circulating for a number of years in Europe and are becoming popular in the United States.

Buprenorphine (BUP) is used for the maintenance of opioid-addicted pregnant women. Because BUP and its main metabolite nor-BUP are excreted into breast milk, a sensitive and specific GC/MS method has been developed, optimized and validated for their determination in breast milk. BUP-d4 was used as internal standard.

Background: A large number of plants, seeds, and berries have been used for medicinal, psychotropic, or aphrodisiac purposes for a thousand years. Mandragora officinarum belongs to the family of Solanaceae and is traditionally known as an aphrodisiac and is closely associated with witchcraft.

Objectives: In this study we report a case of an accidental poisoning after ingestion of some "aphrodisiac" berries and the contribution of the toxicological analysis in the case investigation.

The number of drug-facilitated sexual assault incidents has lately been increased all over the world leading law enforcement agencies and hospital doctors to constant alert. The drugs involved may be benzodiazepines, hypnotics, other sedatives, anesthetics, drugs of abuse or ethanol. The detection of these agents in biologic fluids is difficult, since most of them are shortly acting, and provoke victim's amnesia which in turn leads the victim to report the allegation late.

As genetically modified (GM) foods are starting to intrude in our diet concerns have been expressed regarding GM food safety. These concerns as well as the limitations of the procedures followed in the evaluation of their safety are presented. Animal toxicity studies with certain GM foods have shown that they may toxically affect several organs and systems.

A simple HPLC method has been validated for the determination of sildenafil and its active metabolite (N-desmethylsildenafil) in human blood, using an octadecyl silica (ODS) hypersil column. The chromatographic run time is less than 25 min using a mobile phase of 35:65 (v/v) acetonitrile-0.015 M disodium hydrogen phosphate (Na(2)HPO(4)), triethylamine 0.

The process of toxicological analysis of postmortem specimens can reveal some special difficulty compared to the clinically derived specimens. Many drugs are not stable and the chemical changes that occur in the specimens, due to the hydrolysis processing, the time passed, the drug metabolism, and matrix effect, even when the postmortem interval is short, may affect the interpretation of the toxicological results. This interpretation may be critical, not only to the thorough investigation of different kind of forensic cases, but also to clinical or other cases as it provides very significant challenges to the scientists.

Alcohol is one of the main causes of traffic accidents worldwide. Its use decreases significantly the driving ability of an individual increasing in this way the possibilities of their involvement in motor-vehicle accidents. The above possibilities are increased when a psychoactive substance has been taken in combination with alcohol due to their synergistic effect.

Critical illness has an important impact on the human endocrine system. Very few studies have been performed to elucidate the alterations of the GH/IGF-I axis in acutely ill children. The aim of this study was to investigate several parameters of this axis in children with trauma (TRA) and sepsis (SEP) requiring admission to the pediatric intensive care unit (PICU).
