  • Oral Bacteria May Signal Pneumonia Risk-Oral bacteria may signal which patients are likely to develop healthcare-associated pneumonia, a researcher said here.

    In a small study, there was a sharp divergence between the composition of oral bacteria of ventilated intensive care patients who developed healthcare-associated pneumonia and those who did not, according to Samit Joshi, DO, of Yale University in New Haven, Conn.

    The shift occurred in the days before the patients developed the infection and was characterized by a decline in some forms of bacteria and increases in others, Joshi told reporters at the annual meeting of the Infectious Diseases Society of America.

    The finding has “implications for how we prevent pneumonia in the future,” Joshi said, and may also hold the seeds of new approaches to treatment if it turns out that bacterial changes actually cause the healthcare-associated pneumonia.

    But he cautioned that the genetic method used in the study — a technique called 16S rRNA gene pyrosequencing — can’t currently be employed at the bedside, so that clinical applications of the findings will not be immediate.

    It had long been known that the bacteria of the mouth play a role in dental caries and other dental diseases, Joshi said, but recently there has been a suggestion that they may also play a role in healthcare-associated pneumonia.

  • Botox, dermal fillers can enhance implant outcomes-When placing dental implants, practitioners should consider using Botox and dermal filler agents for patients who need facial volume restorations, according to a presentation at the American Academy of Implant Dentistry (AAID) annual meeting in Las Vegas, October 19-22.
    “Besides creating beautiful smiles, we like to create harmony between the dentofacial complex by addressing the deep lines and wrinkles in the face that can prevent our patients from looking their best,” said Pankaj Singh, DDS, in an AAID press release.
    For older dental implant patients with facial aging, the corners the mouth begin to turn down and wrinkles appear around the lips. Botox can relax affected muscles to raise mouth corners and smooth wrinkles to ensure successful and satisfying outcomes, according to Dr. Singh.
    In addition, dermal filler agents treat fat and collagen volume that causes static lines to develop. “As we age, our body’s production of hyaluronic acid, the body’s natural filler, decreases, which causes facial lines to appear,” Dr. Singh said.
    It takes about two weeks for dermal filler agents to show results, he added, and some patients experience side effects, such as localized pain, infection, bleeding, swelling, redness, bruising, and tenderness in and near the injection site. In addition, results are not permanent, and injections will need to be repeated periodically to maintain the cosmetic improvement.
