Long-term occlusal changes and patient satisfaction in patients treated with and without extractions: 37 years after treatment.

Introduction: The objective of this research was to evaluate the treatment outcomes, long-term occlusal changes, and patient satisfaction after 37 years of nonextraction and extraction treatments.

Methods: Fifty-seven patients with Class I and Class II malocclusion were divided into 2 groups. Group 1 included 16 patients treated with nonextraction therapy, with mean initial (T1), final (T2), and long-term posttreatment (T3) ages of 13.

Anterior tooth alignment and arch dimensions changes: 37-year follow-up in patients treated with and without premolar extraction.

Introduction: The objective of this research was to evaluate the anterior tooth alignment and dental arch dimension changes after orthodontic treatments with and without premolar extractions in the long-term.

Methods: Fifty-seven patients with Class I and Class II malocclusion were divided into 2 groups. Group 1 included 16 patients treated with nonextraction therapy, with mean initial (T1), final (T2), and long-term follow-up (T3) ages of 13.

[Asymmetry of arterial blood pressure in the brachial artery in patients with cerebrovascular pathology].

Twenty-five patients suffering from cerebrovascular pathology coupled with arterial pressure (AP) asymmetry in the brachial arteries underwent an analysis including studies of the clinical picture, angiographic and rheographic readings (REG and RVG of the forearms and hands). It is demonstrated that revelation of a steady and well-defined asymmetry of AP in the brachial arteries associated with pulse weakening or disappearance in the radial artery on the side of AP decrease combined with pronounced asymmetry of the RVG readings for the forearms and hands is an important diagnostic and prognostic sign that points to the involvement into the process (occlusion or stenosis) of the subclavian artery. As a rule, this is coupled with lesions of the other main arteries of the head and may provoke impairment of the cerebral circulation, occurring more frequently in the arteries of the vertebrobasilar system.

[Cerebrovascular disorders in various types of the subclavian steal syndrome].

A total of 51 patients with the subclavian steal-syndrome (SSS) were examined for the clinical picture comparatively to the angiography and ultrasound dopplerography (USDG) data. The clinical manifestations of cerebral circulatory disorders were studied not only in the isolated SSS but also in its different variants realized in association with concomitant lesions of the other branches of the aortic arch. Rarely occurring variants of the SSS were revealed; some of them were discovered for the first time.
