Background and Objectives: The present study was conducted to assess the effects of low dose Midazolam with Propofol and Propofol alone during minor oral and maxillofacial surgeries; to evaluate the level of sedation, post-operative amnesia, and condition of the patient during surgery, patient satisfaction and opinion. Material and Methods: Fifty ASA Grade I and II patients were randomly alloca...

OBJECTIVES/HYPOTHESIS This study evaluated the effects of three levels of bolus consistency (water, thick liquid, and paste) on the nature and duration of physiologic pressure while swallowing in healthy adults using high-resolution manometry (HRM). STUDY DESIGN A case series of healthy adults. METHODS Thirty-four healthy young adults (mean age: 24.29 years) were instructed to swallow 3 mL ...

In order to investigate the possibility of using different materials as bolus in radiotherapy, five samples denoted by S2 S6 were prepared and analyzed by comparison with one available commercial bolus denoted by S1. Sample S1 was a thermoplastic material from Qfix; S2 was a moldable silicon rubber (RTV-530 from Prochima); S3 and S4 were obtained by adding micrometric particles of Al and Cu res...

The tongue is an intricately configured muscular organ that undergoes a series of rapid shape changes intended to first configure and then transport the bolus from the oral cavity to the pharynx during swallowing. To assess the complex array of mechanical events occurring during the propulsive phase of swallowing, we employed tongue pressure-gated phase-contrast MRI to represent the tissue's lo...

Time-resolved MR angiography (MRA) has been proposed as a non-invasive and nonionizing imaging method. Compared with monophasic CTA and MRA it provides better arteriovenous differentiation and functional dynamic information that so far has been gained only with DSA. When contrast-enhanced MRA was first introduced in 1993 acquisition time was in the range of several minutes. In addition the imag...

Giant intracranial aneurysms often present as mass lesions rather than with subarachnoid hemorrhage. Routine computed tomographic (CT) scans with contrast material will generally detect them, but erroneous diagnosis of basal meningioma is possible. Rapid sequential scanning (dynamic CT) after bolus injection of 40 ml of Renografin-76 can conclusively demonstrate an intracranial aneurysm, differ...

Ingested foreign bodies, food bolus impaction, migration or retention of medical devices are frequent, in children as well as in adults. Most of these foreign bodies will naturally pass through the gastro-intestinal tract. Complications are rare but sometimes severe (oesophageal perforations are the most frequent and most feared). We aimed to review the literature on therapeutic management of d...

The dynamics of a bolus transport through the esophagus are largely unexplored. To study this physiological process, we applied multiple intraluminal impedancometry in 10 healthy subjects. Three different protocols were used: 1) liquid bolus administered with subject supine, 2) liquid bolus with subject upright, or 3) semisolid bolus with subject supine. Transit of different parts of a bolus (b...
