Abstract
Background "Breast implant illness" (BII) is a poorly defined cluster of nonspecific symptoms, attributed by patients as being caused by their breast implants. These symptoms can include joint pain, skin and hair changes, concentration, and fatigue. Many patients complaining of BII symptoms are dismissed as psychosomatic. There are currently over 10,000 peer-reviewed articles on breast implants, but at the time of commencing this study, only 2 articles discussed this entity. At the same time, mainstream media and social media are exploding with nonscientific discussion about BII. Methods We have prospectively followed 50 consecutive patients, self-referring for explantation due to BII. We analyzed their preoperative symptoms and followed up each patient with a Patient-Reported Outcome Questionnaire. All implants and capsules were, if possible, removed en bloc. Explanted implants were photographed. Implant shell and capsule sent for histology and microbiological culture. Results BII symptoms were not shown to correlate with any particular implant type, surface, or fill. There was no significant finding as to duration of implant or location of original surgery. Chronic infection was found in 36% of cases with Propionibacterium acnes the most common finding. Histologically, synoviocyte metaplasia was found in a significantly greater incidence than a matched cohort that had no BII symptoms (P = 0.0164). Eighty-four percent of patients reported partial or complete resolution of BII symptoms on Patient-Reported Outcome Questionnaire. None of the 50 patients would consider having breast implants again. Conclusion The authors believe BII to be a genuine entity worthy of further study. We have identified microbiological and histological abnormalities in a significant number of patients identifying as having BII. A large proportion of these patients have reported resolution or improvement of their symptoms in patient-reported outcomes. Improved microbiology culture techniques may identify a larger proportion of chronic infection, and further investigation of immune phenotypes and toxicology may also be warranted in this group.

Abstract
Silicones are widely used as biomaterials for medical devices such as extracorporeal equipments. However, there is often conflicting evidence about their supposed cell- and histocompatibility. Macrophages could mediate silicone-induced adverse responses such as foreign body reaction and fibrous encapsulation. The polarization behaviour of macrophages could determine the clinical outcome after implantation of biomaterials. Induction of classically activated macrophages (CAM) may induce and support uncontrolled inflammatory responses and undesired material degradation. In contrast, polarization into alternatively activated macrophages (AAM) is assumed to support healing processes and implant integration.This study compared the interaction of non-polarized macrophages (M0), CAM, and AAM with commercially available tissue culture polystyrene (TCP) and a medical grade silicone-based biomaterial, regarding the secretion of inflammatory mediators such as cytokines and chemokines. Firstly, by using the Limulus amoebocyte lysate (LAL) test the silicone films were shown to be free of soluble endotoxins, which is the prerequisite to investigate their interaction with primary immune cells. Primary human monocyte-derived macrophages (M0) were polarized into CAM and AAM by addition of suitable differentiation factors. These macrophage subsets were incubated on the materials for 24 hours and their viability and cytokine secretion was assessed. In comparison to TCP, cell adhesion was lower on silicone after 24 hours for all three macrophage subsets. However, compared to TCP, silicone induced higher levels of certain inflammatory and chemotactic cytokines in M0, CAM, and AAM macrophage subsets.Conclusively, it was shown that silicone has the ability to induce a pro-inflammatory state to different magnitudes dependent on the macrophage subsets. This priming of the macrophage phenotype by silicone could explain the incidence of severe foreign body complications observed in vivo.

Abstract
Asymmetric facial expression is generally attributed to asymmetry in movement, but structural asymmetry in the face may also affect asymmetry of expression. Asymmetry in posed expressions was measured using image-based approaches in digitised sequences of facial expression in 55 individuals, N=16 men, N=39 women. Structural asymmetry (at neutral expression) was higher in men than women and accounted for .54, .62, and .66 of the variance in asymmetry at peak expression for joy, anger, and disgust expressions, respectively. Movement asymmetry (measured by change in pixel values over time) was found, but was unrelated to peak asymmetry in joy or anger expressions over the whole face and in facial subregions relevant to the expression. Movement asymmetry was negatively related to peak asymmetry in disgust expressions. Sidedness of movement asymmetry (defined as the ratio of summed movement on the left to movement on the right) was consistent across emotions within individuals. Sidedness was found only for joy expressions, which had significantly more movement on the left. The significant role of structural asymmetry in asymmetry of emotion expression and the exploration of facial expression asymmetry have important implications for evolutionary interpretations of facial signalling and facial expressions in general.

Abstract
In June of 2000, the U.K. Medical Device Agency recommended the removal of Trilucent implants as a precautionary maneuver in response to reports of local inflammatory reactions. This decision allowed the authors to operate on 115 consecutive patients between June of 2000 and January of 2001. On the preoperative examination, the authors found a very high incidence of rippling (66 percent), whereas capsular contracture was seen in only three patients (2.6 percent). Rippling was significantly more common in patients with subglandular implants. Five implants were found ruptured during the operation. This figure, together with the relative ease of implant breakage at removal, shows a premature deterioration of the implant shell. The authors also comment on implant bleeding, which seems common in this type of breast implant. The authors think that this is a possible cause for the rippling phenomenon, resulting from a reduction of the implant content. On the basis of these findings, the authors conclude that Trilucent implants are associated with a poor cosmetic outcome and a high rate of complications.

Abstract
Formation of a granuloma is a common tissue response to the presence of a variety of foreign materials. A silicone granuloma is, by definition, a type of tissue reaction elicited occasionally by silicone. Granulomas of this sort have not engendered a great deal of attention in the scientific literature since their first description in 1964, and they were considered by most surgeons through the 1980s to be an incidental finding of little or no consequence. Since it is tangible and readily visible to juries, the silicone granuloma became a frequent issue in breast implant litigation in the 1990s. Although most other complaints in this litigation have been subjective or causally unrelated to silicone, the presence of a granuloma has been used as a basis of local complication claims and, more creatively, as a mechanism for hypothetical systemic disease occurrence. This review examines the basic science and the clinical literature pertaining to breast implant-related silicone granulomas, viewing them in a context of current clinical thought and frequent issues of litigation. Clinically apparent silicone granulomas are a relatively rare complication of breast implant placement and surgical resection is indicated when they are symptomatic or of diagnostic concern. There is no evidence in the peer-reviewed scientific literature to support frequent plaintiff theories in litigation that silicone granulomas play some role in implant-related systemic disease. In fact, the very existence of such diseases, themselves, is equally unsubstantiated.

Abstract
For nearly 100 years, aesthetic improvement of the aging face has included surgical elevation of the brow. Early attempts to correct brow ptosis were largely unsuccessful. Recognizing the need to modify the frown muscles heralded the achievement of results previously unobtainable. Within the past decade, the minimal incision approach to brow lifting afforded with the endoscope radically changed surgical options in forehead rejuvenation. Further advances have added to these options and have provided a palette of alternatives in aesthetic correction of the upper one-third of the aging face.

Abstract
BACKGROUND The term evidence-based medicine (EBM) is increasingly being used. Physicians, journal editors, insurance companies, and patients are applying its tenets to clinical decision making. Although there are concerns about the overly zealous application of EBM to clinical situations, many of the basic concepts are important in improving decision making. OBJECTIVE To define evidence-based medicine and to review potential problems in basing decision making entirely on less-than-ideal evidence. METHODS We reviewed the EBM literature and looked for examples in dermatology of pitfalls in decision making based on poor evidence. RESULTS Following a definition of EBM, we review problems inherent in anecdotes and uncontrolled trials, including the placebo effect. Examples of medical practice that have been altered by doing more rigorous studies are provided. CONCLUSIONS Concepts of EBM as currently defined should be considered by dermatologic surgeons in assessing the available information for clinical decision making.

Abstract
Surgical augmentation has been performed since 1899, with varying results. Recent developments in endoscopic instrumentation have enabled surgeons to perform many types of procedures through small incisions located at a distance from the surgical site. The transumbilical breast augmentation (TUBA) has advantages over other methods, including a quicker recovery, less pain, and lower chances of complications. This article familiarizes perioperative personnel with TUBA and how to care for the patients who undergo this procedure.
