Forensic veterinary radiology: ballistic-radiological 3D computertomographic reconstruction of an illegal lynx shooting in Switzerland

The lynx, which was reintroduced to Switzerland after being exterminated at the beginning of the 20th century, is protected by Swiss law. However, poaching occurs from time to time, which makes criminal investigations necessary. In the presented case, an illegally shot lynx was examined by conventional plane radiography and three-dimensional multislice computertomography (3D MSCT), of which the latter yielded superior results with respect to documentation and reconstruction of the inflicted gunshot wounds. We believe that 3D MSCT, already described in human forensic-pathological cases, is also a suitable and promising new technique for veterinary pathology.

Dopamine receptor D4 polymorphism predicts the effect of L-DOPA on gambling behavior

BACKGROUND There is ample evidence that a subgroup of Parkinson's disease patients who are treated with dopaminergic drugs develop certain behavioral addictions such as pathological gambling. The fact that only a subgroup of these patients develops pathological gambling suggests an interaction between dopaminergic drug treatment and individual susceptibility factors. These are potentially of genetic origin, since research in healthy subjects suggests that vulnerability for pathological gambling may be linked to variation in the dopamine receptor D4 (DRD4) gene. Using a pharmacogenetic approach, we investigated how variation in this gene modulates the impact of dopaminergic stimulation on gambling behavior in healthy subjects. METHODS We administered 300 mg of L-dihydroxyphenylalanine (L-DOPA) or placebo to 200 healthy male subjects who were all genotyped for their DRD4 polymorphism. Subjects played a gambling task 60 minutes after L-DOPA administration. RESULTS Without considering genetic information, L-DOPA administration did not lead to an increase in gambling propensity compared with placebo. As expected, however, an individual's DRD4 polymorphism accounted for variation in gambling behavior after the administration of L-DOPA. Subjects who carry at least one copy of the 7-repeat allele showed an increased gambling propensity after dopaminergic stimulation. CONCLUSIONS These findings demonstrate that genetic variation in the DRD4 gene determines an individual's gambling behavior in response to a dopaminergic drug challenge. They may have implications for the treatment of Parkinson's disease patients by offering a genotype approach for determining individual susceptibilities for pathological gambling and may also afford insights into the vulnerability mechanisms underlying addictive behavior.

Oil-soluble vitamins: illegal use for lip augmentation.

Fillers for lip augmentation have become more and more popular in recent years and seem to be indispensable in the cosmetic market nowadays. A series of six young females is presented who developed massive swellings and pain after vitamins A and/or E lip augmentation. The vitamins were extracted from gelatinous capsules (Gericaps [Adipharm EAD, Sofia, Bulgaria], Geritamins [Actavis EAD, Balkanpharma-Dubnitsa AD, Bulgaria], or vitamin E yellow gel capsules) and injected by unprofessional physicians and beauticians in different cosmetic centers. Physical examination revealed firm indurations of the lips and perioral skin, tenderness, erythema, and hard dermal nodules. Histological analysis revealed numerous round-to-ovoid cavities of varying sizes, resulting in a Swiss cheese-like appearance, consistent with lipogranulomas. The patients were treated with systemic and intralesional triamcinolone injections and broad-spectrum antibiotics with good clinical response. In conclusion, these cases demonstrate the danger of the use of unregistered products as fillers injected by unprofessional physicians and beauticians.

Non-Substance-Related Disorders: Gambling disorder and internet addiction

Behavioral addictions are highly prevalent and have a major individual and societal impact. Moreover, given the availability and increase of potentially addictive activities in our societal development (e.g. internet, gaming, online pornography) an increase in these types of behavioral disorders is very likely. Gambling Disorders are best studied among the non-chemical addictions. However, effective treatment interventions need to be further developed, in particular for Internet Addiction. Most of the available evidence supports behavioral interventions as first line treatment. Specifically for Gambling Disorder, pharmacotherapy can be an useful augmentation.. Psychiatric comorbidities are frequent in patients with behavioral addictions and negatively affect the course of non-substance-related disorders. Concurrent treatment of these comorbid disorders is advised, although there is a clear need of conducting studies evaluating the effectiveness of integrated treatment approaches.
