This study was designed to correlate histopathological changes in gerbil brain following unilateral primary and secondary ischemia to enzymatic-adenylate cyclase damage. At three hrs permanent occlusion of the right common carotid artery only minimal histological changes were evident in cerebrum, hippocampus, striatum and olfactory tubercle while the enzyme responses were unremarkable. Severe h...

Approximately 3% 11.8% of cases require permanent pacemaker implantation due to atrioventricular block (AVB) after aortic valve replacement (AVR), and determination of conduction disturbances such as left or right bundle branch block by preoperative electrocardiography is correlated with high risk postoperative permanent pacemaker implantation. Intraoperative risk factors include severe calcifi...

Traumatic tooth injuries are common in children. When permanent teeth are involved, it can be a challenge to save these teeth. This clinical case study describes the multidisciplinary treatment of a complex crown fracture and luxation of a right maxillary incisor along with esthetic management. After periodontal surgery including guided bone regeneration and endodontic treatment, we used a glas...

Introduction:Foreign body aspiration is usually a serious condition that is most common among the pediatric population, and rare in adults. In adults, aspiration may be tolerated for a long time.Case Reports:Our first case is a 38-year-old man who presented with a 2-day history of swallowing a foreign body. He was completely asymptomatic. Chest X-ray revealed the presence of 5-cm foreign object...

Atrial Fibrillation (AF) is the most frequent and clinically important form of cardiac arrhythmia. It has been demonstrated that cardiovascular comorbidities such as myocarditis, myocardial infarction, obesity, or pulmonary hypertension (PH) promote remodeling associated with development atrial arrhythmogenic substrates. Right-heart disease (RHD), characterized by chronic right-sided structural...

OBJECTIVE The aim was to evaluate the prevalence and distribution of tooth number anomalies in a Turkish subpopulation. MATERIALS AND METHODS A population of 2722 patients (1532 females and 1190 males; mean age, 12.33 ± 2.5 years) was retrospectively examined to determine the prevalence and distribution of the hypodontia, oligodontia, and hyperdontia using panoramic radiographs. All permanent...

The present case report describes a patient with dual chamber pacemaker whose surface ECG demonstrated paced right bundle branch block pattern suggesting a malpositioned ventricular lead in the left ventricle. However, diagnostic work-up revealed that the lead was appropriately located in the right ventricular apex. Diagnostic maneuvers and clues for differentiating safe right bundle branch blo...

We present the case of a 72-year-old male who underwent a permanent transvenous DDD pacemaker implantation for symptomatic complete heart block. The postoperative surface electrocardiogram (ECG) revealed a right bundle branch block (RBBB) pacing pattern with transition in lead V3 and left bundle branch block (LBBB) in D1, suggesting a malpositioned ventricular lead in the left heart. Malpositio...

It is known that an electrocardiogram (ECG) after transvenous right ventricular (RV) pacing should yield left bundle branch block (LBBB) QRS patterns. When right bundle branch block (RBBB) pacing morphology appears in a patient with a permanent or temporary transvenous RV pacemaker, myocardial perforation or malposition of the pacing lead must be ruled out, even though the patient may be asympt...
