TOPIC: Procedures TYPE: Medical Student/Resident Case Reports INTRODUCTION: We present a case of tracheostomy tube dislodgement during mechanical ventilation leading to subcutaneous emphysema and cerebral air embolism. CASE PRESENTATION: A 33-year-old male with chronic on trach collar was hospitalized from skilled nursing facility for delirium. Past history notable rupture right-sided ophthalmi...

The negative health and socio-economic impacts of emissions associated with domestic fuel burning are widely recognized. Although there has been much progress in the provision electricity to households South Africa, many still rely on solid sources such as wood coal. While various investigations have done reducing household by use polluting fuels improvements combustion efficiency, comparativel...

BACKGROUND Central line insertion is a routine procedure in medical practice. Dislodgement of lines into the vascular system is a rare complication. We noticed that paediatric health care providers (PHCP) contact the cardiac or general paediatric surgeon for extraction of dislodged lines more frequently than using the less invasive percutaneous approach. AIM To study the referral preference o...

BACKGROUND Canine veterinary patients increasingly benefit from implantation of transvenous pacemakers for bradyarrhythmias. No published data exist examining procedural outcomes of pacemaker implantation performed in the preclinical laboratory. The purpose was to review short term complication, infection, dislodgement, penetration rates, plus overall morbidity following pacemaker implantation ...

OBJECTIVE This study aimed to identify factors related to outcomes of the pharyngeal foreign bodies in children and to improve the management protocol of this disease. METHODS The medical records of 131 children with pharyngeal foreign bodies hospitalized in the hospital were retrospectively reviewed. RESULTS Significant differences were observed between the two groups (dislodgement and rem...

Since FOX-7 (1, 1-diamino-2, 2-dinitroethylene) is a relatively new energetic material, little is known about its physical and chemical properties. Therefore, first-principles quantum chemical calculations are used to predict the energies of atoms of FOX-7. Under gentle heating (thermolysis) is likely to cause hydrogen transfer between molecules, producing highly reactive chemical species. Conv...

Effective treatment of vascular gas embolism may be possible with emulsified fluorocarbon compounds. We tested the hypothesis that a fluorocarbon emulsion delivered before gas embolization would enhance bubble motion through the vasculature, favoring more rapid clearance. Air microbubbles were injected into the rat cremaster microcirculation in six groups of rats receiving Perftoran, an emulsif...

A 43-year-old male with alcoholic cirrhosis underwent EGD for hematemesis which revealed bleeding, grade II, lower esophageal varices that were endoscopically ligated with 6 bands. All the bands remained attached to varices at the completion of EGD. Despite apparent initial hemostasis, balloon tamponade was performed one hour later for suspected continued bleeding. Due to suspected continuing b...

BACKGROUND The resistance form is a key factor for a successful crown fabrication. This in vitro study evaluates the effects of proximal grooves and abutment height on the resistance of single cast crowns in molars with inadequate resistance. METHODS Sixty extracted human molars were prepared to possess 20° of total occlusal convergence for single crown fabrication. All of the prepared teeth ...

BACKGROUND There are no published studies comparing the clinical performances of more-viscous glass-ionomer cement (GIC) restorations when placed using conventional and atraumatic restorative treatment (ART) cavity preparation methods to restore root surface caries. METHODS One dentist used encapsulated Fuji IX GP and Ketac-Molar to restore 72 conventional and 74 ART cavity preparations for 1...
