Use of hyaluronic acid for regeneration of maxillofacial bones.

Hyaluronic acid (HA) has been widely used in medicine and is currently of particular interest to maxillofacial surgeons. Several applications have been introduced, including those in which HA is used as a scaffold for bone regeneration, either alone or in combination with other grafting materials, to enhance bone growth. This review aims to analyze the available literature on the use of HA for maxillofacial bone regenerative procedures including socket preservation, sinus augmentation, and ridge augmentation.

Prospective, case-control study on the effect of pregnancy on seizure frequency in women with epilepsy.

To evaluate if pregnancy induces a change in seizure frequency and in percentage of subjects remaining seizure-free. This is a prospective case-control study conducted in our tertiary epilepsy centre. Controls were matched 2:1 with the cases for relevant clinical parameters.

Fibrinogen apheresis in the treatment of peripheral arterial disease.

Background: Fibrinogen is mainly responsible for determining the viscosity of whole blood. In peripheral arterial disease (PAD) the fibrinogen concentration seems to affect the microcirculation flow.

Aim: To study the effects of an abrupt reduction of fibrinogen on the hemodynamics of the lower extremities and the clinical picture of patients with PAD.

A protocol for oral desensitization in children with IgE-mediated cow's milk allergy.

Objectives: To desensitize children with severe immunoglobulin (Ig)E-mediated cow's milk allergy in a period of 6 months by introducing increasing daily doses of cow's milk (CM) in order to enable the child to assume 200 ml of CM daily, or to induce tolerance of the highest possible CM dose.

Study Design: Twenty-one children at least 6 years old with severe IgE-mediated CM allergy were admitted to the study. A convincing history of IgE-mediated CM allergy or a positive double-blind placebo-controlled food challenge with CM confirmed the diagnosis.

[Carotid endarterectomy in the elderly].

The elderly population has the highest risk for developing stroke and the annual death rate is some 394/100,000 population. Moreover, the elderly are the fastest growing segment in our society. In carefully selected patients carotid endarterectomy may provide to prophylaxis against stroke.
