CDC Grand Rounds: Getting Smart About Antibiotics.

MMWR Morb Mortal Wkly Rep 2015 Aug;64(32):871-3

Each year in the United States, approximately two million persons become infected with antibiotic-resistant bacteria, at least 23,000 persons die as a direct result of these infections, and many more die from conditions complicated by a resistant infection. Antibiotic-resistant infections contribute to poor health outcomes, higher health care costs, and use of more toxic treatments. Although emerging resistance mechanisms are being identified and resistant infections are on the rise, new antibiotic development has slowed considerably. Read More

Estimating age in black South African children.

SADJ 2014 Mar;69(2):54-8, 60-1

Forensic dentists are frequently required to determine the age at death of unidentified skeletons, or to age live individuals who have no record/documentation of their chronological age. In order to be of the greatest value, the method used should have the lowest possible standard deviation and be validated for the individual's specific population group. The method most frequently used in Forensic Dentistry for the estimation of age in children, was described by Demirjian et al. Read More
