Vascular access has been the Achilles heel of hemodialysis for many years, and placement of temporary subclavian and internal jugular vein catheters has been a daily practice for the nephrologist. Now, concern about central vein stenosis, well described with the use of subclavian catheters in end-stage renal disease (ESRD), has prompted the use of internal jugular vein permanent catheters to av...

the aim of this study was to evaluate mesiodistal diameter of permanent teeth and evaluating it's distribution in iran. in current study, 850 plastery impressions or 16590 teeth were precisely measured by a digital coulis with 0.01 mm accuracy.the obtained measures of the permanent teeth are shown in table 1. table (4) demonstrates the symmetry of left and right maxillary and mandibular te...

Background: Mucocele is the second most common benign soft tissue tumour occurring in the oral cavity. Clinically, a mucocele is characterized by an increase in volume, with a bubble-like shape that contains saliva, and is similarly colored to that of the normal mucosa or it may present blue coloration, depending on whether it is deep or superficial, respectively. A mucous cyst is common and ha...

Permanent His-bundle pacing (HBP) is a true physiological form of ventricular pacing that has been shown in recent years to be both safe and feasible in clinical practice. However, there are limited data about its long-term performance, especially when compared with both right ventricular and biventricular pacing. In this article, we present a thought-provoking case study that illustrates the u...

Delayed development and eruption of all the permanent molars is a rare phenomenon, which can cause disturbance in the developing occlusion. The eruption of permanent first and second molars is very important for the coordination of facial growth and for providing sufficient occlusal support for undisturbed mastication. In the case described, the first permanent molars were delayed in their deve...

INTRODUCTION Cervical aortic arch is a rare anomaly where-in the ascending aorta arises normally from the left ventricle and extends in such a fashion that the aortic arch is situated high in the neck on either side. This anomaly should be suspected in any child exhibiting a pulsatile swelling in the neck. CASE COMMENTARY An 8 year old child presented with a pulsatile swelling on the right si...

AIMS Atrial fibrillation (AF) is a common comorbidity in bradycardia patients. Advanced pacemakers feature atrial preventive pacing and atrial antitachycardia pacing (DDDRP) and managed ventricular pacing (MVP), which minimizes unnecessary right ventricular pacing. We evaluated whether DDDRP and MVP might reduce mortality, morbidity, or progression to permanent AF when compared with standard du...

Developmental disturbances of permanent teeth can result from trauma to primary teeth because of the proximity of the root of the primary teeth to their permanent successors. We describe the case of a 14-month-old boy who was referred to the baby clinic of the School of Dentistry, Universidad Estadual Paulista, Araçatuba, Brazil, after sustaining a severe trauma that led to intrusion of the rig...

From the University of Michigan Medical Center, Ann Arbor, MI. © 1990 by Association of Pediatric Oncology Nurses. Nursing practices at many institutions advocate the use of occlusive, sterile permanent right atrial catheter (PRAC) dressing change procedures. Few of these practices are based on research data. However, nursing literature suggests that employing simpler procedures or no dres...
