Project description:BackgroundVaginal laxity may result from trauma to the pelvic floor muscle, which may affect patients' sensation and quality of life. Vaginal rejuvenation, including surgical or nonsurgical interventions, aims to improve laxity. In this study, we aimed to establish a strategy for vaginal rejuvenation by comparing surgical and nonsurgical methods.MethodsA retrospective clinical study was performed on patients who complained about vaginal laxity from 2017 to 2019. The degree of vaginal laxity severity was evaluated by vaginal examination in each patient. The patients were categorized as having a light, moderate or severe degree of vaginal laxity, and different correction methods were chosen accordingly. The Female Sexual Function Index (FSFI) questionnaire was administered to the patients preoperatively and at three months and one year after treatment.ResultsSeventeen patients with severe-degree vaginal laxity were treated with vaginoplasty. The total FSFI score was 23.21±2.57 before the operation and significantly increased to 29.36±1.84 (P<0.01) at one year after surgery. Eleven patients with moderate-degree vaginal laxity were treated with vaginoplasty and had a significant improvement in the total FSFI score at one year after surgery (29.86±1.74, P<0.01) compared with the FSFI score before surgery (23.41±2.84). Three patients with moderate-degree vaginal laxity were treated with a CO2 laser and tended to have increased FSFI scores but did not show significant improvement after the operation. CO2 laser treatment was performed on 16 patients with light-degree vaginal laxity. The total FSFI score improved from 23.76±2.35 to 26.16±2.58 at one year (P<0.05).ConclusionsThe strategy for vaginal rejuvenation should be selected based on the degree of vaginal laxity severity. Surgical treatment is suitable for severe- and moderate-degree vaginal laxity while nonsurgical treatment is suitable for light-degree vaginal laxity.

Project description:PurposeWe constructed a custom-made vitreoretinal surgical simulator using a silicone mold and described its practicality.MethodsWe obtained spherical silicone molds, mannequins, and spray material from an internet-based vendor and combined them with expired surgical instruments to complete the simulator. Vitreoretinal experts confirmed the practicality of the simulator after simulated vitrectomy, and the results of the questionnaires were confirmed by nonvitreoretinal experts.ResultsVitreoretinal experts observed that the simulated eyeball and the actual eyeball were similar in size and rigidity and that the intraocular practice swing seemed to be useful for the prevention of complications. The semitransparency and open-sky structure of the silicone material ensured visibility. The simulated membrane, which was spray glue, provided an excellent peeling sensation. In the results of the nonvitreoretinal experts' questionnaires, the average scores of all items were generally high, which supported the claims of the simulator's usefulness.ConclusionThis report describes the simplicity and cost-effectiveness of our custom-made simulator and its contribution in creating an ideal training environment that does not necessitate travel to special facilities that offer a large number of pig eyes and vitreous surgical machines. The simple shape seems to allow many possibilities, and further verification at multiple facilities is necessary.

Project description:A hypertrophic scar is a common dermal fibroproliferative lesion usually treated with topical silicone. Verapamil, a type of calcium channel blocker, is considered a candidate drug for the treatment of hypertrophic scars. Here, we report that the addition of verapamil to topical silicone gel enhances treatment outcomes of hypertrophic scars. Upon creation of hypertrophic scars with the rabbit ear model, varying concentrations of verapamil-added silicone gel (0.1, 1, and 10 mg/g) were applied daily for 28 days. After the animals were euthanised, microscopic measurement was performed for (a) scar elevation index (SEI), (b) fibroblast count, and (c) capillary count. On gross analysis, features of hypertrophic scars were significantly alleviated in the verapamil-added groups. On histologic examination, verapamil-added groups showed (a) reduced SEI (1.93 (1.79-2.67) for control vs 1.34 (1.21-1.51) for silicone only and 1.13 (1.01-1.65) for verapamil-added silicone), (b) fibroblast count 700.5 (599.5-838.5) for control, 613.25 (461-762.5) for silicone only, and 347.33 (182.5-527) for verapamil-added silicone), and (c) capillary formation (52 (35.5-96.5) for control, 46 (28-64.5) for silicone only, and 39.83(24-70) for verapamil-added silicone) (Kruskal-Wallis test, P < .05). On western blot, expression levels of collagen I protein was lower in the 1 mg/g and 10 mg/g verapamil-added silicone compared with control. Therefore, we suggest a therapeutic concentration of verapamil-added silicone gel of at least over 1 mg/g. Further study regarding maximally effective concentration and deeper insight into the mechanism of action should follow.

Project description:BackgroundVaginoplasty is a gender-affirming surgery that is medically necessary for some transfeminine individuals. Little research exists describing vaginal health after the initial recovery from surgery, and evidence-based guidelines for vaginal care practices are unavailable.AimThe study sought to describe self-reported gynecological concerns and vaginal care practices among transfeminine persons who have undergone vaginoplasty.MethodsA total of 60 transfeminine participants 18+ years of age, living in Canada, and who had undergone vaginoplasty at least 1 year prior were recruited through social media, community groups, healthcare provider referrals, and study recontact. Participants completed a cross-sectional, online questionnaire detailing demographics, gynecological concerns, and genital practices and exposures. Hierarchical clustering was used to group participants based on behavioral practices and exposures. Associations between clusters and gynecological concerns were assessed.OutcomesOutcomes included self-reported gynecological concerns within the past year, recent vulvar or vaginal symptoms (past 30 days), and behavioral practices/exposures, including douching with varied products and dilating.ResultsParticipants reported a variety of concerns in the past year, including urinary tract infection (13%) and internal hair regrowth (23%). More than half (57%) had experienced at least 1 recent vaginal symptom, most commonly malodor (27%) and vaginal bleeding (21%). Of participants, 48% were dilating weekly and 52% reported douching in the past 30 days. Four distinct clusters of vaginal practices/exposures were identified: limited exposures; dilating, no douching; dilating and douching; and diverse exposures. No significant associations between cluster membership and gynecological concerns were identified, though cluster membership was significantly associated with surgical center (P = .03). Open-text write-ins provided descriptions of symptoms and symptom management strategies.Clinical implicationsThe results provide insight for clinicians on common patient-reported gynecological concerns and current vaginal care practices and exposures, including symptom management strategies.Strengths and limitationsThis was the first study to investigate vaginal health and genital practices/exposures among a community sample of transfeminine individuals. As participants self-enrolled for a detailed survey and swab collection, individuals experiencing concerns were likely overrepresented.ConclusionTransfeminine individuals reported a range of gynecological concerns outside of the surgical healing period. Genital practices/exposures varied across clusters, but no clear associations between clusters and symptoms were identified; instead, practice/exposure clusters were dependent on where the individual underwent vaginoplasty. There is a need for evidence to inform diagnostics, treatments, and vaginal care guidelines to support vaginal health.

Project description:Gel lubrication is routinely used during gynecological examination to prevent or reduce pain, yet its impact on microbial composition during sampling remains unclear. This study aimed to investigate whether lubricating gel affects the microbial composition of vaginal samples. We included 31 pregnant women presenting during their third trimester to clinics or emergency room and collected 143 unique vaginal samples for 16S amplicon microbial analysis. Vaginal samples were obtained using sterile swabs under various conditions: without gel-immediately frozen (n = 30), with gel-immediately frozen, without gel-at room temperature (RT) for 5 h before freezing, with gel-at RT for 5 h before freezing, and additional sampling after 24 h without gel-immediate freezing. We found that sample collection with gel lubrication influenced specimen quality-half of the gel samples failing to meet processing limitation compared to those without gel. The effect of gel on testing quality dissipated after 24 h. However, when samples met post-sequencing filters, gel lubrication did not alter the microbial composition, individual taxa abundance or alpha and beta diversity. We recommend sampling either before gel exposure or 24 h after. These findings underscore the importance of considering sample collection methodologies in vaginal microbiome studies to ensure high-quality microbial data for accurate analysis.

Project description:BackgroundSilicone breast implants have been widely used for breast augmentation and reconstruction. During this time, silicone breast implants have undergone several modifications to improve their safety, quality, and clinical performance. Complications such as reoperation, capsular contracture, and rupture are risks often associated with breast implants.ObjectivesThe authors conducted a retrospective study to analyze and report complication rates associated with Eurosilicone's (Eurosilicone S.A.S, Apt, Cedex, France) silicone gel-filled breast implants over a period of 5 years.MethodsIn this retrospective clinical study, 2151 women who underwent either breast augmentation or breast reconstruction with Eurosilicone breast implants were diagnosed. Data on early and late complications including implant removal (explantation/exchange), capsular contracture, and rupture were collected using questionnaires, completed by 39 surgeons across Italy.ResultsOf the 2151, only 60 patients (2.78%) required implant removal. Twenty-five patients experienced capsular contracture (Baker Grade III/IV), giving an actual rate of 1.2%. The actual rate of implant rupture confirmed by breast magnetic resonance images was 0.18% (4 implants). Six patients (0.27%) were diagnosed with breast cancer following breast augmentation, and local complications including hematoma (1 patient) and seroma (2 patients) were experienced.ConclusionsThis retrospective clinical study involving Eurosilicone's round and anatomical textured silicone gel-filled mammary implants demonstrates an excellent safety profile through 5 years.Level of Evidence: 2.

Project description:BackgroundSilicone gel implants are regarded as esthetically superior to saline implants, offering a more natural consistency. They are also considered less susceptible to rippling. However, objective measurements and patient-reported outcome studies are lacking. Similarly, minimal data are available quantitating animation deformity.MethodsA 3-year prospective study was undertaken among 223 women undergoing primary subpectoral breast augmentation using either saline (n = 145) or silicone gel (n = 78) implants. Photographs obtained included frontal views with the patient flexing the pectoral muscles. Images were matched, and vertical differences in nipple position were measured. Breast implants were evaluated using high-resolution ultrasound to detect any ripples or folds at least 3 months after surgery. Outcome surveys were administered. Statistical analysis included the χ2 test, point-biserial correlations, and a power analysis.ResultsRespondents reported visible rippling in 18% of women and palpable rippling in 32% of patients, with no significant difference between women treated with saline and silicone gel implants. Ripples were detected on ultrasound scans in 24% of women with saline implants and in 27% of women with silicone gel implants (difference not significant). Ripples were more common in women with lower body mass indices. Fifty percent of patients demonstrated nipple displacement <1 cm on animation. Nipple displacement occurred either up or down with equal frequency and a mean overall nipple displacement of zero.ConclusionsSaline and silicone breast implants produce similar degrees of rippling, as determined on outcome surveys and ultrasound examination. Animation deformities tend to be minor and well-tolerated.

Project description:Upper lip scars are at risk of hypertrophy. Our center therefore uses microporous tape and silicone sheeting for postoperative scar care following cleft lip repair. However, some babies have previously ingested their silicone sheeting, which has the potential for respiratory compromise or gastrointestinal obstruction. Self-dry silicone gel is reportedly also effective for preventing hypertrophic scars. Hence, we sought to test whether silicone gel, which cannot be ingested whole, might be non-inferior to silicone sheeting for controlling against upper lip scar hypertrophy. This was a mixed prospective and retrospective case-controlled clinical trial involving patients undergoing unilateral cleft lip repair, 29 of whom received standard postoperative silicone sheeting (control group) and another 33 age-matched consecutive patients who received self-dry silicone instead. The Vancouver scar scale, visual analogue scale and photographically assessed scar width assessments were the same in both groups at six months after surgery. In conclusion, silicone gel appears to be non-inferior to silicone sheeting for postoperative care of upper lip scars as judged by scar quality at six months, but silicone sheeting has the safety disadvantage that it can be swallowed whole by babies. It is thus recommended that silicone gel be used for upper lip scar management in babies.

Project description:BackgroundDue to the complexity of reconstructing wide inferomedial orbital wall fractures, silicone sheets are the preferred choice of reconstructive material. Nevertheless, it is crucial to remove the silicone sheet postoperatively due to the risk of delayed complications associated with its placement.MethodsWe developed a procedure in which a silicone sheet implanted in the orbit can be extracted through the nasal cavity by removing the fractured portion of the medial orbital wall.ConclusionThis procedure enables the utilization of silicone sheets, which are suitable for intricate orbital reconstruction, without any concerns regarding delayed complications.
