Introduction The purpose of this lecture is to introduce you to terminology used in microbiology. The lecture will: 1. cover different classification schemes for grouping bacteria, especially the use of the Gram stain 2. describe the different types of bacteria 3. discuss bacterial structure and the function of the different bacterial components 4. discuss the distinguishing characteristics of ...

introduction: the potential benefit of ultrasonography for detection of thoracic bone fractures has been proven in various surveys but no comprehensive conclusion has been drawn yet; therefore, the present study aimed to conduct a thorough meta-analytic systematic review on this subject. methods: two reviewers independently carried out a comprehensive systematic search in medline, embase, isi w...

introduction: elevated intracranial pressure (icp) is a major and potentially lethal disorder in patients admitted to the emergency department (ed). several methods are being used to investigate for elevated icp. here we assessed and compared the diagnostic accuracy of two existing tools of ophthalmoscopy and optic nerve ultrasonography in detection of elevated icp. methods: 131 participants wi...

conclusions rotem can be used to detect postoperative hemostatic changes following cardiac surgery appropriately and can be useful to choose suitable blood products that may reduce the need for blood transfusion, contributing to better patient blood management. background coagulopathy after cardiopulmonary bypass (cpb) may lead to increased morbidity and mortality. routine conventional coagulat...

Gram stains of positive blood cultures are the most important factor influencing appropriate therapy. The sooner appropriate therapy is initiated, the better. Therefore, it is reasonable to expect that the sooner Gram stains are performed, the better. To determine the value of timely Gram stains and whether improvement in Gram stain turnaround time (TAT) is feasible, we compared data for matche...

Laboratory diagnosis of APS relies on the demonstration of a positive test for aPL. In clinical practice, the gold standard tests are those that detect beta2GPI-dependent aCL or LA. The question on the use of anti-beta2GPI asa routine diagnostic test remains unanswered, and testing for these antibodies should be only performed in very selected cases and not as an alternative to aCL or LA testin...

Gram stains of 87 different clinical samples were prepared by the laboratory's conventional methods (automated or manual) and by a new single-slide-type automated staining instrument, GG&B AGS-1000. Gram stains from either heat- or methanol-fixed slides stained with the new instrument were easy to interpret, and results were essentially the same as those from the methanol-fixed slides prepared ...

there is limited data in the literature on the normal size of the anterior fontanelle. this cross- sectional study was to determine normal values of anterior fontanelle size on the first day of life, using standard methods. anterior fontanelle size was measured in 400 term and healthy neonates delivered at the shariati hospital, tehran, iran. examination included assessment of head circumferenc...
