Abstract
Silicon has made its breakthrough in various industries, including clinical and biomedical applications. Silicon-based biomaterials that were fabricated into various types of scaffolds may attract interest due to their highly favorable properties covering their excellent biocompatibility, high surface area, mechanical strength, and selectivity depending on their application including film, hydrogel, nanoparticles, and so on. Silicon-based materials have also shown exciting results involving cell culture, cell growth, as well as tissue engineering. In this article, a simple review compromising the evaluation of silicon's unique properties has been discussed and followed by the application of the silicone-based product in future perspectives in biomedical fields. The review goals are to widen and inspire broader interest in silicone-based materials in wound healing research.

Free Silicone Injections to the Breast: Delayed Complications and Surgical Management of Sequelae. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2020; 8:e3208. [PMID: 33299689 PMCID: PMC7722574 DOI: 10.1097/gox.0000000000003208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 09/01/2020] [Indexed: 11/26/2022]
Abstract
This case describes a healthy 37-year-old woman who presented with bilateral breast pain and nodules years after receiving free silicone injections to her breasts. Mammogram revealed extremely dense breasts with innumerable bilateral masses of various sizes. Ultrasound was non-diagnostic due to poor penetration and artifact from silicone. Histologic examination revealed vacuolated histiocytes and innumerable cystic spaces containing material consistent with silicone. Patient underwent bilateral nipple-sparing mastectomy with immediate reconstruction using tissue expanders. This case highlights the potential for serious complications developing years after free silicone injections as well as our team’s surgical management of these complications.

Abstract
Filler injections belong to the most frequently performed noninvasive beautifying procedures. When done correctly they are generally well tolerated. However, a number of factors, such as poor filler quality, and particularly host as well as user dependent filler reactions may lead to unwanted effects. These may be early, late, or delayed events with characteristics for each of them. Temporary fillers almost invariably cause temporary side effects whereas those of permanent fillers may last forever. Some fillers are notorious for their poor safety profile; for example, silicone is banned in the European Union and the United States but nevertheless used by many practitioners and beauticians. Many fillers can be identified in histopathologic sections allowing specific measures to be instituted.

Abstract
Fillers belong to the most frequently used beautifying products. They are generally well tolerated, but any one of them may occasionally produce adverse side effects. Adverse effects usually last as long as the filler is in the skin, which means that short-lived fillers have short-term side effects and permanent fillers may induce life-long adverse effects. The main goal is to prevent them, however, this is not always possible. Utmost care has to be given to the prevention of infections and the injection technique has to be perfect. Treatment of adverse effects is often with hyaluronidase or steroid injections and in some cases together with 5-fluorouracil plus allopurinol orally. Histological examination of biopsy specimens often helps to identify the responsible filler allowing a specific treatment to be adapted.

Abstract
There has been much debate concerning the pathologic consequences of diabetes on the plantar fat pad and its subsequent association with the development of a foot ulcer. This review article documents two theories regarding pathophysiology in diabetic foot ulcer formation as they are related to the plantar fat pad and discusses current treatment options for this pathophysiological phenomenon. Traditionally, fat pad atrophy in diabetic patients was thought to result as an irregular arrangement of collagen fibrils within the septal walls as a result of glycation as well as diminishing adipocyte size due to thickened septal walls. Contrary to this traditional theory, a model depicting distal fat pad migration from under the metatarsal heads has been described in the diabetic patient. Such pad migration renders the metatarsal heads vulnerable to increased pressure, which, in turn, predisposes to foot ulceration. This migratory fat pad theory plays a significant role in approaches to the prevention of diabetic foot ulceration and subsequent amputation. Various methods of fat pad supplementation and claw toe management are impacted by the pathophysiological changes described and new avenues of therapy may be based on these changes.

Abstract
Modern medical use of injectable soft-tissue augmentation fillers has evolved from the introduction of bovine collage implants to an array of synthesized materials in the current domestic and foreign markets. The concept of augmentation has moved from simple lines, scars, and wrinkles to revolumizing the aging face. A brief overview of the past, present, and future injectable fillers is presented.

Abstract
BACKGROUND This study aimed to assess and compare the tissue response to small- and large-volume injections of pure liquid silicone in rats. METHODS The study used 25 Sprague-Dawley rats. Two different injection sites were determined for a single rat, and 5000 centistoke liquid silicone was injected subdermally using 0.2-0.3 ml (small volume) and 1 ml (large volume) injections. After the injections, 15 animals were killed at 4 weeks and 10 animals at 10 weeks. Tissue responses were evaluated under a light microscope. RESULTS At week 4, the numbers of lymphocytes and neutrophils were higher in the small-volume injection group. At week 10, the number of neutrophils decreased, and the numbers of macrophages and foreign body giant cells increased in the small-volume injection group, whereas the intensity and type of infiltrate in the large-volume injection group did not change significantly. The thickness of the fibrous capsule was greater in large-volume injection group at weeks 4 and 10. The thickness of the fibrous capsule did not change significantly in either group through time. CONCLUSIONS Purified high-density liquid injectable silicone causes a low-grade and well-tolerated inflammatory response during the long term and can be used when given as small-volume injections.

Abstract
Disruption of the body's plantar fat pad can occur as a result of one of three mechanisms: simple fat pad atrophy associated with age-related degeneration, steroid use, or collagen vascular disease. Actual or relative displacement in to the underlying osseous prominences may be seen in association with structural deformity of the foot. Disease states such as diabetes may alter the normal structural integrity of soft tissues through nonenzymatic glycation leading to increased stiffness and thus reduced attenuating capacity. Fat pad atrophy, regardless of the cause, is often associated with substantial emotional, physical, productivity, and financial losses. In situations where the patient is sensate, the resultant skin on bone situation is extremely painful, especially when walking.
