Multicenter Study Comparative Study Controlled Clinical Trial
Safety and effectiveness of small and large gel-particle hyaluronic acid in the correction of perioral wrinkles.
FDA-approved for the correction of moderate-to-severe facial wrinkles and folds, small gel-particle hyaluronic acid (SGP-HA, Restylane, Medicis Aesthetics, Inc., Scottsdale, AZ) and large gel-particle hyaluronic acid (LGP-HA, Perlane, Medicis Aesthetics, Inc., Scottsdale, AZ) were studied to evaluate their safety for the correction of oral commissures, marionette lines, upper perioral rhytides and nasolabial folds (NLFs). ⋯ Both SGP-HA and LGP-HA were found to be safe and effective for the correction of perioral wrinkles and folds, with few differences among treatment areas Both investigator and patient GAIS evaluations indicated aesthetic improvement after SGP-HA and LGP-HA treatment in the perioral area.

The authors retrospectively reviewed medical records of patients who were diagnosed as having drug-induced urticaria at Siriraj Hospital of Mahidol University (Bangkok, Thailand) between October 2004 and April 2007. One hundred and forty-seven drugs were presumed as causing acute urticaria. Females were affected more commonly than males. ⋯ Antibiotics were the most frequent causes of drug-induced urticaria, of which cephalosporins were the most common causative drugs. Oral NSAIDs significantly had the shortest median onset of urticaria. After discontinuing the culprit drugs, the reactions usually disappeared within a few days.

Nanotechnology is a rapidly growing discipline with important implications for consumers, patients, physicians and investigators. In an era when nanotechnology is being both incorporated into educational requirements for medical fields such as radiology and oncology and vigorously pursued and developed by cosmeceutical companies, dermatology is falling behind. A survey was conducted to ascertain knowledge, attitudes and perception of nanotechnology in dermatology teaching programs. ⋯ The survey results indicate a significant gap in dermatology training. Participants indicated a need for more training and education in the area of nanotechnology, and called for more research to evaluate the potential pitfalls associated with nanomaterials as well and to seek new advances in diagnostic and therapeutic modalities.
