Effect of periodontal disease on oxidative stress markers in patients with atherosclerosis.

Objectives: The aim of this study was to investigate the effect of periodontal inflammation on oxidative stress in patients with atherosclerosis by considering serum and saliva total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI).

Materials And Methods: In the study, there were 4 groups, with 20 individuals in each group. These groups consisted of individuals who had periodontitis with atherosclerosis (group A-P), were periodontally healthy with atherosclerosis (group A-C), were systemically healthy with periodontitis (group P), and were systemically and periodontally healthy (group C).

Effect of periodontitis on oxidative stress parameters in patients with rheumatic heart valve disease.

Objective: The aim of this study was to evaluate the effects of periodontitis on oxidative stress parameters by investigating serum and gingival crevicular fluid (GCF) total antioxidant capacity (TAOC), total oxidant status (TOS), and oxidative stress index (OSI) values in patients with rheumatic heart valve disease (RHVD).

Materials And Methods: The study population comprised 76 patients, who were divided into four groups: chronic periodontitis with RVHD (RV-CP), periodontally healthy with RVHD (RV-C), systemically healthy with chronic periodontitis (CP), and systemically and periodontally healthy (C). Demographic, periodontal, and echocardiographic parameters were measured.

Valproic Acid as a Cause of Transient Atrio-Ventricular Conduction Block Episodes.

Herein we share, to our knowledge for the first time, a a case of valproic acid use complicated by symptomatic atrio-ventricular conduction block episodes on Holter monitoring. Symptomatic atrio-ventricular block episodes should be considered as an unusual side effect of valproic acid despite normal blood therapeutic level. Before consideration of pacemaker implantation in such cases, valproic acid usage should be investigated, and dose reduction should be attempted.

Atrial Fibrillation Triggered By Drug-Induced Bradycardia.

Atrial fibrillation (AF) is the most frequently observed arrhythmia in clinical practice. Many causative factors have been identified from well-known structural heart disease to less understood triggers. Both sympathetic and parasympathetic (vagal) stimuli are able to trigger paroxysms of AF.

Impact of Chronic Rheumatic Valve Diseases on Large Vessels.

BACKGROUND AND AIM OF STUDY: Rheumatic valvular heart disease, which remains a common health problem in developing countries, has numerous consequences on the heart chambers and circulation. The study aim was to investigate the effects of chronic rheumatic valve disease on the diameters of the descending aorta (DA) and inferior vena cava (IVC). METHODS: A total of 88 patients with echocardiographically documented rheumatic valvular heart disease and 112 healthy controls were enrolled into the study.
