RESUMEN
5F-MDMB-PICA has been detected in products sold on the internet as well as in biological samples since 2016. It is associated with serious adverse health and behavioral effects and even death. Herein we report on twelve cases with proven 5F-MDMB-PICA consumption, including three fatalities, four cases of driving under the influence of drugs and five other criminal acts. In these cases, 5F-MDMB-PICA was detected in postmortem blood or serum. Concentrations ranged from 0.1-16ng/mL. In some blood (serum) and urine samples, the hydrolysis metabolite of 5F-MDMB-PICA (M12) could also be detected. In this case series, co-consumption with other drugs occurred in 9 of 12 cases, most commonly alcohol, cannabis and other contemporary SCs. In five cases, 4F-MDMB-BINACA was also detected. The described cases demonstrate various adverse effects that might be associated with 5F-MDMB-PICA. Observed physical adverse effects were mainly balance deficiencies and ocular effects such as reddened conjunctivae, glassy eyes and delayed or unresponsive pupil light reactions. Observed mental and behavioral effects were mainly changing moods, aggression, confusion, erratic behavior, mental leaps, disorientation, slowed reaction, logorrhea and slurred speech. Due to the fast changing market of synthetic cannabinoids, data on such new appearing substances are basically scarce. Because of the limited number of studies on pharmacological properties of synthetic cannabinoids, reports of findings in human samples along with corresponding case history descriptions can be valuable for the interpretation of upcoming routine cases.

We report the case of a 65-year-old man who was attacked and killed by a female elephant that had previously escaped from a nearby circus. According to a witness the man was lifted up by the tusks, flung into the air and stomped upon. At autopsy the body showed signs of severe blunt force trauma and impalement, including multiple lacerations of the skin, a crushed thorax, a spinal fracture and a fractured humerus. The spinal cord and the major abdominal vessels were severed. There have been very few elephant attacks in Europe; this is the first reported case in Germany.

Bcl-2 has been shown to exert its antiapoptotic activity predominantly at the level of mitochondria by preventing cytochrome c release. Whether Bcl-2 is involved in the regulation of mitochondrial function prior to an apoptotic stimulus remains elusive. Using functional and spectrophotometric measurements in an inducible PC12-Tet-on-bcl-2 cell line we demonstrate that induction of Bcl-2 overexpression rapidly reduced cytochrome b and c levels as well as complex I activity. To confirm that these changes were specific for Bcl-2 we generated a bcl-2 antisense construct under the control of the tetracycline responsive promotor. Transient transfection with this antisense plasmid prevented both the decrease of cytochrome b and c levels and the loss of complex I activity. The decrease of cytochrome b levels was paralleled by a decrease of cytochrome b mRNA levels while Northern blot analysis of cytochrome c mRNA expression did not reveal any overt changes in Bcl-2 cells. We propose that the antiapoptotic properties of Bcl-2 are related to the reduction of mitochondrial complex I activity and lowered mitochondrial cytochrome b and c levels.
