Telangiectasia is dilatation of the subpapillary venous plexus of the epidermis of the lower limbs, which can lead to aesthetic embarrassment. Before treating telangiectasia, patient history and clinical examination help establishing its origin. It can be with isolated, associated reticular drainage veins, or be part of superficial venous insufficiency. Several types of treatment have been proposed. Microsclerotherapy is the most effective and least costly. Muller's phlebectomy can be performed when telangiectasia is fed by large reticular veins, either afferent or efferent. Treatment by laser and pulsed light appear best reserved to treatment of finer venous dilatations, either complementary or after failure of sclerotherapy.
In this paper there are shown chemical and physical methods of euthanasia of vertebrate animals. All methods are divided into three categories: A) Acceptable methods of euthanasia, B) methods acceptable only for unconscious animals, C) methods that are not acceptable for euthanasia. The acceptability or non-acceptability of the method is determined by ethic or aesthetic conceptions and also by conceptions of the personnel safety and the environment. There is provided a table of acceptable methods of euthanasia. Recommendations of working group of the Federation of Laboratory Animal Science Association (FELASA) were taken into consideration in this paper. The survey can be useful for the experimenters and personnel concerned with laboratory animals.

Separating hype from the truth in dental marketing can be frustrating and it is difficult at best for the average dentist to evaluate the safety and efficacy of new products and techniques. Keynote clinicians are presenting information and influencing other dentists without the scientific evidence to support their claims. For the benefit of our patients, the system needs to change. It will not come soon, but until more evidence-based testing is commonplace and made readily available to the practicing dentist, most dentists will continue tradition-based practices.
