The Effect of Periodontal Treatment on the Reactive Hyperemia Index. A 1-Year Follow-Up Pilot Study.

Background: Periodontitis is a chronic multifactorial inflammatory disease of the supportive tissues of the teeth. In more recent years, remarkable epidemiological and pathophysiological associations between periodontitis and cardiovascular disease (CVD) have been presented. Whether or not treatment of periodontitis is valuable for primary or secondary prevention of cardiovascular disease, has not yet been fully established.

The association between periodontitis and cardiovascular risks in asymptomatic healthy patients.

Background: Periodontitis is a chronic multifactorial inflammatory disease of the supportive tissues of the teeth. Pathophysiological evidence suggests a possible common inflammatory background between periodontitis and cardiovascular diseases (CVD). Pathological and epidemiological associations between these two diseases have been presented, but are still debated.

Association between the degree of obstructive sleep apnea and the severity of COVID-19: An explorative retrospective cross-sectional study.

Obstructive sleep apnea (OSA) on its own, as well as its risk factors, have been found to be associated with the outcome of Coronavirus disease 2019 (COVID-19). However, the association between the degree of OSA and COVID-19 severity is unclear. Therefore, the aim of the study was to evaluate whether or not parameters to clinically evaluate OSA severity and the type of OSA treatment are associated with COVID-19 severity.

Elevated Coronary Artery Calcium scores are associated with tooth loss.

Aim: This study explores the association between Coronary Artery Calcium (CAC) scores and dental pathology such as missing teeth, the (peri-apical) health status and restoration grade of the teeth, and the grade of alveolar bone loss seen on a dental panoramic radiograph (Orthopantomograph-OPG).

Materials And Methods: In this retrospective cross-sectional study, data was collected from three hospitals spread in the Netherlands. Patients were included when a CAC score and an OPG were available, both recorded within a maximum period of 365 days from 2009-2017.

[An (un)conventional autogenous tooth transplantation].

A 15-year-old boy was referred to an Oral and Maxillofacial Surgery department because of a persistent tooth 85 and a malposition of tooth 45. Following additional examination, it was concluded that the root formation of tooth 45 was already completed. Furthermore, it was horizontally impacted against the inferior border of the mandible.

Long-term results of 44 cross-over bypasses.

Forty-four patients with an unilateral iliac obstruction were treated with a cross-over bypass. The ASPI at rest in the recipient leg was 0.53 +/- 0.

Thoracic outlet syndrome after corrective surgery for pectus excavatum.

Two patients are described who developed a thoracic outlet syndrome (TOS) after undergoing Ravitch's operation for the correction of pectus excavatum. In one case the syndrome developed a few days after surgery, whereas in the second patient it manifested more gradually. A third patient presented with latent TOS and pectus excavatum.

Controlled hypothermia in carotid endarterectomy.

Successful carotid endarterectomy under controlled hypothermia, induced by shell cooling, is described. The patient, whose ipsilateral vertebral and contralateral internal carotid arteries were obstructed, and whose contralateral external carotid artery was stenosed, had presented with recurrent TIA's and amaurosis fugax. Some observations on the indication for and technique of hypothermia are made.

Semi-closed thromboendarterectomy of the femoro-popliteal artery (results of 142 consecutive cases, 5 years after operation).

Semi-closed thromboendarterectomy with the aid of a ring stripper appears not yet to have been abandoned as a method of reconstruction in occlusions in the femoro-popliteal tract. In a series of 142 operations, 5 years postoperatively, 44% of the stripped vascular tracts were still patent and 41% were occluded. Eighteen patients, in whom 20 operations had been performed, had died less than 5 years after the operation.
