Association among Oral Health,Apical Periodontitis,CD14 Polymorphisms,and Coronary Heart Disease in Middle-aged Adults

Introduction

There is evidence to suggest that an association exists between oral infections and coronary heart disease (CHD). Subjects presenting lesions of endodontic origin (LEOs) or pulpal inflammation had an increased risk of developing CHD. However, findings concerning systemic manifestations of apical periodontitis (AP) remain controversial. An association between CD14 gene polymorphisms and atherosclerosis-associated diseases has been shown, but there are no data regarding an association between CD14 polymorphism and AP. This study evaluated associations between clinical oral health status, CD14 polymorphisms, and CHD.

Methods

A case-controlled clinical trial was designed to compare middle-aged adults with acute myocardial infarction or unstable angina (n = 51) within 12 months of the acute event defined as first manifestation with healthy controls (n = 49). Participants were matched for age, sex, and socioeconomic status. Indicators of oral disease and compliance were evaluated. CD14 polymorphisms were analyzed by restriction fragment length polymorphism–polymerase chain reaction.

Results

CHD subjects had a higher prevalence of oral diseases and lower compliance to oral preventive strategies than healthy controls. Multivariate analysis showed a positive association between missing teeth (odds ratio [OR] = 1.37; 95% confidence interval [CI], 1.02–1.85), the number of LEOs (OR = 4.37; 95% CI, 1.69–11.28), chronic periodontitis (OR = 5.87; 95% CI, 1.17–29.4), and CHD. No statistically significant association emerged between the CD14 C(−260)T and the CD14 C(−159)T polymorphism, endodontic or periodontal disease, and CHD.

Conclusions

Chronic oral diseases may increase the risk of CHD and may be an unconventional risk factor for CHD.     

Epileptic and non-epileptic paroxysmal motor phenomena in newborns

Objective: The aim of this study is to provide an extensive overview of the clinical features of neonatal paroxysmal motor phenomena, both self-limited, related to the immaturity of the central nervous system, and pathological (epileptic and non-epileptic), in order to help the diagnostic approach.

Methods: We reviewed the scientific literature about epileptic and non-epileptic paroxysmal motor phenomena in newborns.

Results: Paroxysmal motor phenomena in newborns represent a challenge for the clinicians due to the different underlying pathophysiological mechanisms. A proper differential diagnosis is required.

Conclusions: There are some clinical features that may help clinicians with the differentiation among physiological and pathological, epileptic, and non-epileptic events. However, further investigations are often needed to identify the cause. A continuous synchronized video–electroencephalogram (EEG)–recording, interpreted by an expert in neonatal neurology, remains the gold standard to prove the epileptic origin of a paroxysmal motor phenomenon.
