Physician-Industry Collaboration: Organizational Considerations for the Future of Innovation and Growth in Dermatology
The U.S. medical environment continues to evolve with issues from Privacy to EMR, Insurance regulations, Physician Access and Healthcare Reform, and MACRA (Medicare Access and CHIP Reauthorization Act) on the discussion table. Not since the advent of Medicare and Medicaid in the mid 1960ās, have we seen such widespread changes in the medical healthcare environment (Centers for Medicare and Medicaid Services). Physicians, industry, patients and consumers are affected by the changes. These four groups have historically worked as separate entities, but are now key stakeholders in the future of dermatology. As stakeholders collaborating in building a future together, the dermatologists/physicians will help to ensure and preserve the quality of patient care and best patient outcomes. In the Executive Forum, leaders from the Womenās Dermatologic Society and Industry, explored five important areas: 1) A five-year outlook of Dermatology and Medicine; 2) Access of Industry to Dermatologists and Trainees; 3) The New Practice Environment; 4) Doing Things Differently; and 5) Unmet Specialty Needs. The collaborative group explored solutions for our specialty and the patients we serve
ArteFillĀ® Permanent Injectable for Soft Tissue Augmentation: II. Indications and Applications
Patients ask for procedures with long-lasting effects. ArteFill is the first permanent injectable approved in 2006 by the FDA for nasolabial folds. It consists of cleaned microspheres of polymethylmethacrylate (PMMA) suspended in bovine collagen. Over the development period of 20Ā years most of its side effects have been eliminated to achieve the same safety standard as todayās hyaluronic acid products. A 5-year follow-up study in U.S. clinical trial patients has shown the same wrinkle improvement as seen at 6Ā months. Long-term follow-up in European Artecoll patients has shown successful wrinkle correction lasting up to 15Ā years. A wide variety of off-label indications and applications have been developed that help the physician meet the individual needs of his/her patients. Serious complications after ArteFill injections, such as granuloma formation, have not been reported due to the reduction of PMMA microspheres smaller than 20Ā Ī¼m to less than 1% āby the number.ā Minor technique-related side effects, however, may occur during the initial learning curve. Patient and physician satisfaction with ArteFill has been shown to be greater than 90%
ArteFillĀ® Permanent Injectable for Soft Tissue Augmentation: I. Mechanism of Action and Injection Techniques
After more than 25Ā years of research and development, in October 2006 ArteFillĀ® became the first and only permanent injectable wrinkle filler to receive FDA approval. ArteFill is a third-generation polymeric microsphere-based filler, following its predecessor ArtecollĀ®, which was marketed outside the United States between 1994 and 2006. ArteFill is approved for the correction of nasolabial folds and has been used in over 15,000 patients since its U.S. market introduction in February 2007. No serious side effects have been reported to date according to the FDAās MAUDE reporting database. ArteFill consists of polymethylmethacrylate (PMMA) microspheres (20% by volume), 30ā50Ā Ī¼m in diameter, suspended in 3.5% bovine collagen solution (80% by volume) and 0.3% lidocaine. The collagen carrier is absorbed within 1Ā month after injection and completely replaced by the patientās own connective tissue within 3Ā months. Each cc of ArteFill contains approximately six million microspheres and histological studies have shown that long-term wrinkle correction consists of 80% of the patientās own connective tissue and 20% microspheres. The standard injection technique is subdermal tunneling that delivers a strand of ArteFill at the dermalāsubdermal junction. This strand beneath a wrinkle or fold acts like a support structure that protects against further wrinkling and allows the diminished thickness of the dermis to recover to its original thickness
Epidermal Cooling Crystal Collar Device for Improved Results and Reduced Side Effects on Leg Telangiectasias Using Intense Pulsed Light
Laser and Intense Pulsed Light Therapy for the Esthetic Treatment of Lower Extremity Veins
Clinical and pathophysiologic correlates of 1064-nm Nd:YAG laser treatment of reticular veins and venulectasias
Background: The goal of sclerotherapy, laser therapy, and intense pulsed-light therapy is to produce long-term, cosmetically significant elimination of disfiguring leg veins. This study examines the histologic and clinical effects of using a 1064-nm Nd:YAG laser system on lower extremity vessels. Design: A single treatment using the following parameters: wavelength, 1064 nm (multiple synchronized pulsing); spot size, 6 mm; pulse duration, 14 milliseconds (single pulse); and fluence, 130 J/cm2. Setting: Private dermatology practice. Patients: Thirteen women (mean age, 38.5 years) with blue venulectasia, 0.5 to 1.5 mm in diameter (class 2), and reticular veins, 1.5 to 3.0 mm in diameter (class 3), on the thighs. Main Outcome Measures: Examination of treated and untreated areas by 2 masked observers using macrophotography (1, 2, 3, and 6 months after treatment), Doppler, and optical chromatographic changes. Findings from three 2-mm punch biopsies from treated (immediately and 4 weeks after treatment) and untreated sites. Routine histologic examination; special stains (for elastic and connective tissue and for mucopolysaccharides); and immunohistochemical analysis for expression of the heat shock protein hsp70, tie2 (an endothelial cell-specific receptor tyrosine kinase), and transforming growth factors Ī²1 and Ī²2. Results: Eight patients (62%) manifested 75% to 100% clearing of treated vessel surface area. Treated areas revealed perivascular hemorrhage, thrombi, fragmentation and homogenization of elastic fibers, and eosinophilia of vessel walls. Expression of hsp70 and transforming growth factor Ī² was increased in treated vessels. Conclusions: Our data confirm the effectiveness of 1064-nm Nd:YAG laser treatment in clearing dilated lower extremity veins, probably by heat-induced vessel damage and subsequent fibrosis. Maintenance of clearing was achieved for up to 6 months. However, the presence of recanalized thrombi in some of the specimens suggests the potential for long-term vessel reappearance
