Practice Guideline
Platelet transfusion: a clinical practice guideline from the AABB.
The AABB (formerly, the American Association of Blood Banks) developed this guideline on appropriate use of platelet transfusion in adult patients. ⋯ The AABB cannot recommend for or against platelet transfusion for patients receiving antiplatelet therapy who have intracranial hemorrhage (traumatic or spontaneous). (Grade: uncertain recommendation; very-low-quality evidence).

Management of multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis: current status and future prospects.
Resistance in Mycobacterium tuberculosis arises from man-made selection of genetic mutants that result from spontaneous chromosomal alterations. Thus, drug-resistant tuberculosis (TB) is generally due to inappropriate treatment regimen, poor drug quality, erratic drug supply and poor patient adherence to treatment, reflecting failure in the implementation of an effective TB control programme. Multidrug-resistant TB (MDR-TB) usually denotes bacillary resistance to at least isoniazid and rifampicin. ⋯ Further exploration is required regarding the use of immunotherapy. The recent emergence of extensively drug-resistant TB (XDR-TB), representing MDR-TB with additional bacillary resistance to fluoroquinlones and one or more of the second-line injectable drugs -kanamycin, amikacin and capreomycin, threatens the global control of TB. Given the escalating size of the problem of MDR-TB and XDR-TB worldwide, gigantic instillation of resources is required for control of this formidable challenge, largely through more accurate and rapid drug susceptibility testing (especially for rifampicin and fluoroquinolone), regular drug-resistance surveillance, development of new antituberculosis drugs and other therapeutic modalities, intensive infection control, especially in HIV care settings, as well as strengthening of currently functioning DOTS and Drug-Resistance Programmes.

Comparative Study
Diagnostic CT scans: assessment of patient, physician, and radiologist awareness of radiation dose and possible risks.
To determine the awareness level concerning radiation dose and possible risks associated with computed tomographic (CT) scans among patients, emergency department (ED) physicians, and radiologists. ⋯ Patients are not given information about the risks, benefits, and radiation dose for a CT scan. Patients, ED physicians, and radiologists alike are unable to provide accurate estimates of CT doses regardless of their experience level.
