[Dental compromise for bite closing in patients with minimal or negative overjet]. / Compromesso dentale per la chiusura del morso in pazienti con overjet minimo o negativo.

The Authors evaluate the most common techniques to close the bite in patients with no overjet, then they suggest a method (anterior cross-bite elastics) that can obviate some of the disadvantages experienced using those techniques.

[Bonding of "E"]. / Bandaggio degli "E".

When mixed dentition therapy is indicated, the Authors suggest the banding of second deciduous molars to avoid the risk of demineralization of first permanent molars. The method suggested is supported by few clinical cases, shown in the figures, where heavy forces are exerted against the second deciduous molar.

Activators and inhibitors of the fibrinolytic system in maturity-onset diabetes mellitus without thromboembolic manifestations.

In patients with maturity-onset diabetes mellitus without thromboembolic manifestations, significant increases in both fibrinolytic and antifibrinolytic activity were demonstrated. The increased fibrinolytic activity observed under basal conditions could be due to the continuous release of plasminogen activators from damaged endothelial cells. This hypothesis is supported by the fact that the higher fibrinolytic activity observed in diabetics is followed by a lesser increase in fibrinolytic activity than in controls after the venous occlusion test. The main antiplasmins, except alpha 2-antiplasmin, were significantly higher in diabetics, and their levels were not affected by sex, metabolic regulation, retinopathy, duration of the disease or cholesterolemia. On the contrary, weight, therapy and triglyceridemia significantly influenced the levels of some antiplasmins. Furthermore, hypertriglyceridemia and hypercholesterolemia were associated with a reduction of fibrinolysis. Thus, these conditions may further increase the risk of thromboembolic complications of diabetes mellitus.
