Delayed granulomatous reaction to hyaluronic acid gel injection

Injectable hyaluronic acid (HA) derivatives are the most used resorbable dermal fillers used for soft tissue augmentation. While their use is considered safe, there have been reports of cutaneous granulomatous reactions.We describe the clinical, radiological, and cytological findings in a patient who presented a full year after cosmetic treatment with HA injections and discuss the various treatment options. Level of Evidence: Level V, therapeutic study

Remarketing Rauscher Farm to the Community of Clinton, MA

In a compact town like Clinton, MA, every effort should be made to preserve land for environmental conservation. This is what the town achieved when purchasing Rauscher Farm in 2008. A group of residents in town had led the campaign to preserve the last remaining large open space within the community. Over a decade later we devoted our efforts in this project to examine all aspects of the relationship between Rauscher Farm and the people of Clinton. We have provided a set of recommended action items that the Rauscher Farm Management Subcommittee can pursue. We hope that our comprehensive investigation, analysis, and recommendations may all help to serve the best interest of the Rauscher Farm Management Subcommittee, the people of Clinton, and Rauscher Farm itself

Physiochemical Characteristics of Calcium Hydroxylapatite (CaHA)

© 2018 The American Society for Aesthetic Plastic Surgery, Inc. The clinical performance of fillers in soft tissue augmentation depends upon their physiochemical properties, anatomical areas injected, interaction with the recipient, and the skill and experience of the physician. Scientific measures of filler properties facilitate appropriate selection of treatments for optimal treatment outcomes, and inform adjustments to treatments that improve patient safety and aesthetic outcomes. The rheological properties of calcium hydroxylapatite (CaHA), elastic modulus (G\u27) and viscosity, coupled with its capacity to offer both immediate results and continued stimulation of collagen type I deposition, support its distinction as an ideal treatment for the volume loss characteristic of aging. Furthermore, the comparatively higher G\u27 of CaHA offers a physiochemical basis for the clinical performance observed by the authors, especially in regions such as the temple and chin, where the force exerted by CaHA against bone permits expansion of overlaying tissue, permitting it to behave as a liquid implant
