Abstract
BACKGROUND Silicone injection can cause numerous posttreatment complications-including debilitating pain, cellulitis, abscesses, overlying skin compromise, and siliconomas distorting overlying tissues-that can be difficult to manage. OBJECTIVES The authors evaluate liposuction as a treatment for patients experiencing complications from silicone injections to the gluteal region, to both preserve aesthetic appearance and minimize further risk of complication from these procedures. METHODS Eight patients (7 women and 1 man) who presented consecutively to us between 2010 and 2013 with complications from silicone injections to their gluteal region were enrolled in this study. Each patient was evaluated by computed tomography scan and a 0 to 6 visual analog scale for pain. Emergency room (ER) visits, previous hospital admissions, and cellulitis requiring antibiotics in the 12 months prior to treatment were recorded. Patients were treated with ultrasonic and standard liposuction followed by lipotransfer into the gluteal musculature. A Student t test was used for statistical comparison of pre- and postoperative values. RESULTS Average patient age was 36 years (range, 25-43 years). All patients initially presented with intense pain as assessed by a visual analog scale; by the 12th week postoperatively, the entire cohort experienced remission in pain. At 1 year postoperatively, no patients had infections (vs 75% preoperatively; P = .028), visited the ER (vs 50% preoperatively; P = .058), or were hospitalized (vs an average of 1.5 hospitalizations per patient preoperatively; P = .066). CONCLUSIONS Liposuction with immediate intramuscular fat transfer for buttock augmentation appears to be a safe surgical option that preserves aesthetic appearance for patients with gluteal silicone toxicosis.

Abstract
PURPOSE This study sought to confirm, through histologic evaluation, the vitality and viability of the island osteoperiosteal flap (i-flap) in a rabbit tibia model. MATERIALS AND METHODS In four rabbits, an osteotomy was performed on the tibial aspect of the right leg. A bone flap was raised, but the periosteal attachment was kept intact. The free-floating i-flap was separated from the rest of the bone by a silicone sheet. The rabbits were to be sacrificed after 1, 2, 4, and 8 weeks and histologic samples examined. RESULTS All surgeries were accomplished successfully; however, three animals showed fractured tibiae within a few days after surgery and were sacrificed immediately after the fractures were discovered. The fourth rabbit was sacrificed at 4 weeks. Histologic specimens showed vital new bone in the i-flap area and signs of remodeling in the transition zone and the original basal bone. CONCLUSION The i-flap remained vital. This suggests potential for use in bone augmentation strategies, particularly for the alveolar split procedure.

Abstract
This review discusses treatment strategies for wrinkles and skin defects through an in-depth overview of current soft tissue fillers utilized within the fields of dermatology and plastic surgery. From the review, it is evident that the utilization of different materials for various skin abnormalities is extremely wide in scope. Many clinicians have adopted their own preferences based on not only the knowledge provided by their experience but also the respective profiles of each individual filler, including their efficacy, practicality and safety. With the ongoing emergence of commercially available products designed for soft tissue augmentation, the market will continue to present new and improved treatment options. Although the search for the perfect or most ideal filler is far from over, this review demonstrates that there are a number of commercially available products that are more than acceptable to both patients and clinicians in the treatment of wrinkles and other skin defects.

Abstract
PURPOSE To develop a novel method to repair canalicular lacerations using silicone tubes. METHODS A total of 47 adult patients (47 eyes) with canalicular lacerations were collected from the outpatient department from November 2010 to December 2012. The age ranged from 16 to 53 years. Among the 47 eyes, 37 had lower canalicular lacerations, 6 had upper canalicular lacerations, and 4 had bicanalicular lacerations. A soft probe was made using a stainless steel acupuncture needle, which was inserted into the lumen of the proximal part of the catheter to increase its rigidity. The probe was then inserted into the lacrimal sac and nasolacrimal duct. After retrieval of the catheters, the two ends of the silicone tube were securely tied (end to end) to the catheters. The silicon tube outside the nostril formed a U-shape. The catheters were then pulled upward until the silicone tube was completely located in the canalicular system. The catheters were cut off of the silicone tube near the site of the connection. The two ends of the silicone tube were cut short, -2mm out of the lacrimal punctum, and tied securely, end to end. The length of the tube between the upper and lower punctum was adjusted to ensure that no tension was present in the medial cathus, and the suture was removed through the nostril. The silicone tube was removed 3-10 months after this novel canalicular intubation procedure (NCI). RESULTS All cases were anatomically rehabilitated after surgery. The silicone tube was removed after implanted in 3-10 months (mean 4.5 +/- 1.3 months), the average follow-up time was 11.8 months after removal. In total, 45 eyes in all 47 eyes (95.74%) were free from obstruction. Among them, 41 eyes (91.11%) achieved complete success (completely disappearance of epiphora after tube removal), 4 eyes (8.89%) achieved partial success (irritation occurs under stimulation conditions, such as wind or cold conditions), 4 eyes showed postoperative tearing, with three eyes having inferior lacrimal duct laceration, and one eye with superior canalicular laceration. Apart from two cases (4.26%) suffering inferior punctum splitting, no other associated issues occurred with the silicone tube or iatrogenic injury and lacrimal complications. CONCLUSION For adult patients with canalicular laceration, the NCI was an effective, atraumatic surgery, which has fewer complications than traditional canalicular suture.

Abstract
OBJECTIVE To observe the surgical therapeutic effects of dacryorhinocystotomy under nasal endoscope combined with the application of modified silicone mold implantation for postoperative recurrent dacryocystitis. METHOD The research method is to conduct the dacryorhinocystotomy under nasal endoscope to 23 cases(24 eyes) of recurrent dacryocystitis, in the process of which modified silicone mold is implanted under the nasal mucosa. RESULT During a follow-up of 6-12 months to the 23 cases (24 eyes), 18 eyes were cured, 6 eyes were getting setter and there was no recurrence. CONCLUSION It's concluded that the modified silicone mold implantation can avoid the recurrent atresia of the aperture created by the dacryorhinocystotomy, which proves that the combination with the modified silicone mold implantation in dacryorhinocystotomy is an effective treatment method of curing recurrent dacryocystitis.

Abstract
BACKGROUND Faecal incontinence is a complex and distressing condition with significant medical and social implications. Injection of perianal bulking agents has been used to treat the symptoms of passive faecal incontinence. However, various agents have been used without a standardised technique and the supposed benefit of the treatment is largely anecdotal with a limited clinical research base. OBJECTIVES To determine the effectiveness of perianal injection of bulking agents for the treatment of faecal incontinence in adults. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Register of trials (25 May 2012), ZETOC (3 May 2012), clinical trials registries (3 May 2012) and the reference lists of relevant articles. SELECTION CRITERIA All randomised or quasi-randomised controlled trials comparing the use of injectable bulking agents for faecal incontinence with any alternative treatments or placebo were reviewed to evaluate the therapeutic effects. Case-control and cohort studies were also reviewed to assess risks and complications associated with the treatments. DATA COLLECTION AND ANALYSIS Two review authors (YM and CN) assessed the methodological quality of eligible trials and independently extracted data from the included trials using a range of pre-specified outcome measures. MAIN RESULTS Five eligible randomised trials with a total of 382 patients were identified. Four of the trials were at an uncertain or high risk of bias.Most trials reported a short term benefit from injections regardless of the material used, including placebo saline injection. One study demonstrated dextranomer in stabilised hyaluronic acid (NASHA Dx) to be more effective than sham injection but with more adverse effects. Dextranomer in stabilised hyaluronic acid (NASHA Dx) was better than sham injections at six months (65/136, 48% versus 48/70, 69% participants not improved, defined as less than 50% reduction in incontinence episodes, RR 0.70, 95% CI 0.55 to 0.88; with more incontinence free days (3.1 days compared with 1.7 in the sham treatment group, MD 1.40 days, 95% CI 0.33 to 2.47). Another study comparing silicone material (PTQ™) to saline injections was too small to demonstrate a clinical benefit compared to the control injection of normal saline.A silicone biomaterial (PTQ™) was shown to provide some advantages and was safer in treating faecal incontinence than carbon-coated beads (Durasphere®) in the short term.Similarly, there were short term benefits from injections delivered under ultrasound guidance compared with digital guidance.No long term evidence on outcomes was available and further conclusions were not warranted from the available data. None of the studies reported patient evaluation of outcomes and thus it is difficult to gauge whether the improvement in incontinence scores matched practical symptom improvements that mattered to the patients. AUTHORS' CONCLUSIONS One large randomised controlled trial has shown that this form of treatment using dextranomer in stabilised hyaluronic acid (NASHA Dx) improves continence for a little over half of patients in the short term. However, the number of identified trials was limited and most had methodological weaknesses.

Abstract
BACKGROUND Complications resulting from enlargement of the penis by applications of unknown types of silicone and mineral oils are well described. Surgical removal of the tissue altered by inflammation leads to the development of defects of various sizes, often circular from the glans penis to the scrotum. The options of subsequent surgical treatment described in literature are not very extensive. Most defects are managed with skin grafting, rarely V-Y advancement or bilateral scrotal flaps. METHODS We present a 36-year-old patient after application of unknown silicone material into the penis for cosmetic enlargement. After the application developed severe inflammation with ulceration and necrosis around the penis. Conservative treatment was not effective, therefore, the infiltrated skin with subcutaneous tissue of the entire penis was surgically removed. The resulting defect was covered by implantation of the penis under the skin of the scrotum. RESULT There were no complications in the postoperative course, pain that was present before the surgery immediately subsided. Skin suture healed completely within 14 days. Three months after the surgery the patient returned to normal sexual life. CONCLUSIONS Implantation of the penis under the skin of the scrotum is a fast, safe and effective method that can treat most of the circular skin defects of the penis. Scrotal skin is thin, soft, elastic and creates abundant and good cover around the entire penis.

Abstract
A cochlear implant (CI)-associated local drug delivery system based on dexamethasone (DMS) was developed with the purpose to inhibit the growth of fibrotic tissue which influences the signal transmission from the CI to the neurons of the inner ear. For the realization of a targeted DMS delivery the following concepts were combined: modification of the silicone-based electrode carrier by incorporation of DMS and a DMS-containing polymeric coating chemically attached on the surface of the electrode carrier. It was demonstrated that the coated CI showed a high coating stability in a simulated implantation procedure. The in vitro drug release studies in a quasi-stationary model revealed a faster DMS release in the initial phase originating from the DMS-containing coatings and then a lower and sustained DMS release originating from the DMS-loaded silicone carrier. The performed in vitro biocompatibility study confirmed that the released DMS was non-toxic for cultured spiral ganglion cells.

Abstract
PURPOSE To observe the clinical efficacy of spherical headed silicone implantation in the treatment of chronic dacryocystitis under nasal endoscopy. METHODS Twenty six patients (31 eyes) with chronic dacryocystitis were subjected to spherical headed silicone implantation under topical anesthesia (lacrimal passage and nasal mucosal surface). Lacrimal passage irrigation was performed daily throughout the first postoperative week , and once each month thereafter. RESULTS All spherical headed silicone tube placements were successfully performed. The operative time ranged from 6 to 11 minutes. Symptoms of epiphora were immediately ameliorated post-operatively, and irrigation demonstrated patency of the lacrimal system in all patients. All patients were followed from 7 to 24 months, during which symptoms of tearing were improved. The lacrimal ducts of 27 eyes (87.7%) were normal. The lacrimal ducts of 4 others (12.3%) were still blocked. Lacrimal passage irrigation was open and secretion disappeared in 28 eyes (90.3%). Tearing was observed in 3 eyes (9.68%). CONCLUSION Spherical headed silicone tube implantation under nasal endoscopy is successful in relieving symptoms of tearing.

Abstract
The injection of bulking agents has been described as a useful treatment of urinary and fecal incontinence. Among them, silicone implants have shown benefits in patients with internal anal sphincter (IAS) injury. We describe two patients with a history of hemorrhoidectomy and IAS injuries, which underwent placement of silicone implants. The implants were inserted into the intersphincteric space and the IAS under ultrasound guidance. The Wexner continente score fell from 17 and 19 before treatment, to 6 and 8 at six months follow up, respectively. Patients had no postoperative complications or implants migration. In our patients, injection of silicone implants improved fecal continence score, without postoperative complications or implants migration at six month follow up.

Abstract
While Male-to-female transgender persons (TG) are believed to often engage in sex work and have high HIV infection risk, little is known about demographics, surgical and hormone use history, risk behaviors and HIV prevalence. Between March and October 2005, 474 TG from Bangkok, Chiangmai, and Phuket were surveyed using venue-day-time sampling. Of 474 participants, overall HIV prevalence was 13.5%. Most participants had completed at least secondary or vocational education (79.2%), gender self-identified as female (89.0%), had received money, gifts or valuables for sex (60.8%), and reported hormone use (88.6%). Surgical history was taken from 325 participants. Of these, 68.6% reported some form of surgery and 11.1% had undergone penile-vaginal reconstructive surgery. In multivariate analysis, being recruited from a park/street; older age, anal sex role identification as "versatile" and anal sex debut before age 13 were independently associated with HIV prevalence. The development, implementation and evaluation of culturally appropriate sexual health interventions for Thai TG is urgently needed.

Abstract
Keloids are aesthetically disfiguring and severely disabling. The optimal treatment remains undefined. This clinical study, evaluate the efficacy and side effects of combined topical silicone and 5-Fluorouracil on the prevention of keloids. In this double blind randomized clinical trial, fifty patients with keloids were randomly allocated in two groups. The control group were treated by perilesional surgical excision of keloids combined with topical silicone and the trial group were treated with adjuvant treatment of intralesional 5-Fluorouracil. All patients were examined and assessment was done by an independent observer. the data collected were analyzed by SPSS statistical software with using tables and χ square tests. 75% of the cases in the trial group were keloid free 21% have keloid partially improvement and 4% have keloid recurrence, compared to patients in the control group respectively: 43%, 35% and 22%, findings suggest that efficacy of 5-Fluorouracil combined with topical silicone used for the prevention of keloid is comparable to other modality. The lack of any serious side effects and the evidence of recurrence at one year of follow-up make this an effective tool for the prevention of keloids.

Abstract
For more than two decades silicone has successfully been employed in the treatment and prevention of hypertrophic scars and keloids as a painless noninvasive modality with few side effects. In the present trial, after 3 months of treatment the Patient Scar Assessment Scale demonstrated that patient satisfaction with the silicone application was significantly higher compared to placebo. When treatment was stopped after 3 months, the topical silicone spray did not exhibit any lasting long-term impact on the objective results of scar formation. Due to the significant differences in patient satisfaction once treatment has ended and since the administration is safe and simple, any final decision on treatment indication should be tailored to the patient and include the psychological well-being of the patient as well as the temporary improvement in scar formation during treatment.

Within the available data, however, we found no reliable evidence for effectiveness of one treatment over another in improving faecal incontinence. Larger well-designed trials with adequate numbers of subjects using reliable validated outcome measures are needed to allow definitive assessment of the treatment for both effectiveness and safety.

Abstract
BACKGROUND Onion extract gel (OE) and 0.5% hydrocortisone, silicone and vitamin E lotion (HSE) are two over-the-counter preparations used to enhance the cosmesis of keloids and hypertrophic scars. OBJECTIVE To determine the tolerability and efficacy of OE versus HSE versus placebo in subjects with keloids and hypertrophic scars. METHODS Thirty subjects (> or =18 years) with keloids or hypertrophic scars were randomly assigned to one of three study preparations for 16 weeks. Scar volume was measured at baseline and weeks 4, 8, 12 and 16. Subjects and blinded investigators assessed scar parameters (induration, erythema, pigmentation alteration, pain, itching, tenderness and cosmetic appearance) and patient satisfaction at each visit using a visual analog scale (VAS). Data analysis included: mean percentage change (MPC) for subjects completing the study (n = 15); the mixed model test to determine differences between the groups over time; and the Kruskal-Wallis test for the analysis of differences in subjects' satisfaction within the three groups over 16 weeks for subjects who completed at least one follow-up visit (n = 21). RESULTS All three preparations were well tolerated with the exception of a mild acneiform-like eruption in one OE patient. Significant improvements were obtained with OE in volume, length, width and induration and with HSE in volume, length, induration, erythema and pigmentation alteration. There was a trend showing that a higher percentage of subjects were satisfied with OE than with HSE or placebo. The Mix Model Analysis (MMA) showed significant improvements with OE over placebo in investigator cosmetic assessment, lesion induration, pigmentation and tenderness and with HSE over placebo in investigator cosmetic assessment, lesion induration, pigmentation and erythema. Improvements in erythema and pigmentation were significantly greater in HSE than in OE. CONCLUSION Both OE and HSE were more effective than placebo in the management of hypertrophic scars and keloids.

Abstract
Our expanding understanding of the physiological and immunological conditions of the skin and, in particular, the aging face, has prompted a growing field of aesthetic technology. Restorative procedures are taking advantage of improved and refined biotechnology, which continues to evolve at a rapid pace. Whereas surgical correction of skin laxity was the norm in years past, there are now many topical options available to encourage healthy, youthful skin, and an ever-growing, increasingly perfected depot of minimally invasive, injectable dermal volumizers and stimulators, collectively referred to as dermal fillers. The growth indicators for this market are as striking as the science. However, successful use of dermal fillers is not only a function of the quality of science leading to improved biocompatibility but also the "art" of client selection, filler application and vigilant follow up. Even the "ideal" filler is subject to unique interactions with both the practitioner and the patient. This article presents a review of the safety and efficacy of the most commonly used dermal fillers with emphasis on those approved for facial aesthetics. The subtleties of improved filler technologies that impact tissue acceptance and reaction, measures of effectiveness and a comparison of wrinkle-reduction outcomes, the nature and incidence of acute and chronic tissue reaction, and a discussion of recommended or preferred filler applications are presented.

Abstract
Soft-tissue augmentation of the face is an increasingly popular cosmetic procedure. In recent years, the number of available filling agents has also increased dramatically, improving the range of options available to physicians and patients. Understanding the different characteristics, capabilities, risks, and limitations of the available dermal and subdermal fillers can help physicians improve patient outcomes and reduce the risk of complications. The most popular fillers are those made from cross-linked hyaluronic acid (HA). A major and unique advantage of HA fillers is that they can be quickly and easily reversed by the injection of hyaluronidase into areas in which elimination of the filler is desired, either because there is excess HA in the area or to accelerate the resolution of an adverse reaction to treatment or to the product. In general, a lower incidence of complications (especially late-occurring or long-lasting effects) has been reported with HA fillers compared with the semi-permanent and permanent fillers. The implantation of nonreversible fillers requires more and different expertise on the part of the physician than does injection of HA fillers, and may produce effects and complications that are more difficult or impossible to manage even by the use of corrective surgery. Most practitioners use HA fillers as the foundation of their filler practices because they have found that HA fillers produce excellent aesthetic outcomes with high patient satisfaction, and a low incidence and severity of complications. Only limited subsets of physicians and patients have been able to justify the higher complexity and risks associated with the use of nonreversible fillers.

Abstract
Lay (non-medical) injection of silicone may lead to serious clinical consequences. Most reports of illicit cosmetic procedures have dealt with failed, lay attempts at breast augmentation. Although these procedures have resulted in severe pneumonitis and alveolar hemorrhage, reports of similar complication after lay attempts at buttock augmentation have been sparse. We describe one of these rare cases and review the literature on clinicopathologic sequelae of lay attempts at cosmetic procedures using commercially available silicone preparations.

Abstract
We evaluated the effects of chondroitinase ABC on axonal regeneration across peripheral nerve gaps. We compared axonal regeneration after 15-mm tibial nerve resection and repair with a silicone tube filled with type I collagen gel (negative control group), with a silicone tube filled with type I collagen gel containing chondroitinase ABC at three different concentrations (2.5 units/mL, 5 units/mL, 10 units/mL) (chondroitinase ABC groups), and with an autologous nerve segment (nerve autograft group). Electrophysiological and histological assessments were carried out 12 weeks after surgery. In the electrophysiological study, compound muscle action potentials (CMAPs) and nerve conduction velocities (NCVs) were recorded in all groups except the negative control group. Although both CMAPs and NCVs were highest in the nerve autograft group, there were no significant differences among the three chondroitinase ABC groups in either parameter. Histological findings were consistent with electrophysiological results. Based on these findings, we conclude that topical injection of chondroitinase ABC can significantly increase the critical length of nerve gap repair by tubulization or artificial nerve placement.
