Four bold questions about hand asepsisMay 24, 2019Hand asepsis is one of the most critical components of surgical asepsis to lower the risk of nosocomial diseases. In this column, we answer four critical and bold questions related to hand asepsis. Could you lose your driver's license by scrubbing in? With the emergence of alcohol-based hand-rub solutions (ABHRS), you may be concerned that with repeated use, you could have enough alcohol in your bloodstream to lose your driver's license. Alcohol is indeed absorbed through the skin, and you inhale plenty of it while scrubbing (or "rubbing"). So could a breathalyzer test be positive? A 2006 Australian study1 looked at 20 health-care workers and their use of ABHRS repeatedly over a short period of time: 30 applications in an hour! Then serum and breath ethanol and isopropanol absorption were assessed. Traces of ethanol were detectable in the breath of 30 percent of subjects at one to two minutes after application and in the serum of 10 percent of them at five to seven minutes postexposure. Serum isopropanol levels were undetectable at all time points. Even though ethanol did have a positive result, whether through cutaneous absorption or inhalation of fumes, neither level would be considered positive during a police-issued …
Cone-beam computed tomography in dentistry and oral surgeryMay 24, 2019Computed tomography (CT) has revolutionized our ability to detect subtle hard and soft tissue abnormalities of the maxillofacial region. Cone-beam computed tomography (CBCT) is creating much buzz amongst veterinary dentists when it comes to dental/maxillofacial diagnostic tools. What is the difference between CBCT and conventional CT? Rather than a collection of thin, closely spaced slices obtained with a fan-shaped beam of conventional CT, CBCT has both an X-ray generator and detector that rotates around the patient, capturing data with a cone-shaped beam. Both modalities can be used to create very helpful 3-D reconstructions of the areas of interest, although CBCT provides increased detail of dentoalveolar structures. One veterinary study compared CBCT's diagnostic image quality with that of 64-multidetector row CT sagittal slices. Four blinded evaluators compared CBCT and 64-multidetector row CT images. Trabecular bone, enamel, dentin, pulp cavity, periodontal ligament space, lamina dura and "overall impression" were scored. Images captured with CBCT were found to be significantly superior in image quality when compared to images acquired with 64-multidetector CT in all categories.1 Inka, the jaguar My first experience with CBCT was with a patient from the Elmwood Park Zoo in Norristown, Pa. Inka is a five-year-old jaguar that fractured …
