Smokeless tobacco use is common in various parts of the world. In Turkey a type of smokeless tobacco called "Maras powder" is widely used in southeastern region. Smoking is known to have an adverse effect on nitric oxide and cardiovascular risk factors. The aim of this study was to evaluate whether there is difference between the effects of Maras powder and cigarette smoking on the cardiovascular risk factors and nitric oxide levels. ⋯ We conclude that Maras powder has similar adverse effects on nitric oxide level and cardiovascular risk parameters and thereby it appears to be harmful as cigarette smoking.

Adverse event reports (AERs) submitted to the US Food and Drug Administration (FDA) were reviewed to assess the bleeding complications induced by the administration of antiplatelets and to attempt to determine the rank-order of the association. ⋯ The data strongly suggest the necessity of well-organized clinical studies with respect to antiplatelet-associated bleeding complications.

Maxillary bone losses often require additional regenerative procedures: as a supplement to the procedures of tissue regeneration, a platelet concentrate called PRF (Platelet Rich Fibrin) was tested for the first time in France by Dr. Choukroun. Aim of the present study is to investigate, clinically and histologically, the potential use of PRF, associated with deproteinized bovine bone (Bio-Oss), as grafting materials in pre-implantology sinus grafting of severe maxillary atrophy, in comparison with a control group, in which only deproteinized bovine bone (Bio-Oss) was used as reconstructive material. ⋯ The use of PRF and piezosurgery reduced the healing time, compared to the 150 days described in literature, favoring optimal bone regeneration. At 106 days, it is already possible to achieve good primary stability of endosseous implants, though lacking of functional loading.
