Masculinizing hormonal treatment in transgender men has the potential to increase the level of androgens at end organs, including the pilosebaceous unit. Androgen-induced sebocyte growth and differentiation, sebum production, and infundibular keratinization may underlie the development of acne vulgaris among patients receiving this therapy. Despite the incidence of treatment-related acne and the unique considerations in treating transgender men, studies addressing this topic among this patient population are limited. Generally, standard guidelines for the treatment of acne can be followed in treating these patients; however, several medical, social, and psychologic factors should be considered. The aim of this article is to familiarize dermatologists with the sensitivities and challenges of treating acne in transgender male individuals.

Autologous breast reconstruction using muscle-sparing free flaps are becoming increasingly popular, although microvascular free flap reconstruction has been utilised for autologous breast reconstructions for >20 years. This innovative microsurgical technique involves meticulous dissection of artery-vein bundle (perforators) responsible for perfusion of the subcutaneous fat and skin of the flap; however, due to unpredictable anatomical variations, preoperative imaging of the donor site to select appropriate perforators has become routine. Preoperative imaging also reduces operating time and enhances the surgeon's confidence in choosing the appropriate donor site for harvesting flaps. Although computed tomography angiography has been widely used for preoperative imaging, concerns over excessive exposure to ionising radiation and poor iodinated contrast agent enhancement of the intramuscular perforator course has made magnetic resonance angiography, the first choice imaging modality in our centre. Magnetic resonance angiography with specific post-processing of the images has established itself as a reliable method for mapping tiny perforator vessels. Multiple donor sites can be imaged in a single setting without concern for ionising radiation exposure. This provides anatomical information of more reconstruction donor site options, so that a surgeon can design a flap of tissue centralised around the best perforator, as well as a back-up perforator, and even a back-up flap option located on a different region of the body. This information is especially helpful in patients with a history of scar tissue from previous surgeries, where the primary choice perforator is found to be damaged or unsuitable intraoperatively. In addition, chest magnetic resonance angiography evaluates recipient site blood vessel suitability including vessel diameters, course, and branching patterns. In this article we provide a broad overview of various skin flaps, clinical indications, advantages and disadvantages of each of these flaps, basic imaging technique, along with advanced sequences for visualising tiny arteries in the groin and in the chest. Post-processing techniques, structure of the report and how automation of the reporting system improves workflow is described. We also describe applications of magnetic resonance angiography in postoperative imaging.

In India, social determinants of health, including poverty, domestic violence, and inadequate social support disproportionately affect women, leaving them more vulnerable to depression than men. We conducted a metaethnography to synthesize qualitative data from 13 studies (1987-2017) that explored women's experiences and perceptions of depression in India. We used a feminist standpoint to critically examine how gender shapes these experiences and perceptions. Indian women's experiences of depression were embedded in their social worlds. Women perceived interpersonal conflict, caregiving burden, domestic violence, financial insecurity, adverse reproductive events and widowhood as causes of depression. Women used cultural expressions to describe physical, emotional, and cognitive distress. The detrimental impact of discriminatory social conditions, gender inequalities, and traditional gender roles on Indian women's mental health highlights the need for gender-sensitive mental health research and practice that can attend to women's sociocultural context and promote values of gender equality and social justice.

Innovative surgery is defined as a novel procedure, a significant modification of a standard technique, or a new application of an established technique. Although innovation is a crucial part of improving patient care in plastic surgery, there are various ethical considerations and dilemmas in performing unvalidated techniques and procedures, especially for non-life-threatening indications. The aim of this study was to gain a better understanding regarding the motivations and ethical considerations of plastic surgeons in their decision to perform innovative operations. An anonymous, institutional review board-approved, online survey was sent to members of the American Society of Plastic Surgeons and other international plastic surgeons worldwide. The survey asked respondents to rank various factors that influence their decisions to perform innovative plastic surgery, both reconstructive and aesthetic, on a five-point Likert scale. Seven hundred thirty-three of 26,028 plastic surgeons (response rate, 2.9 percent) responded to the survey. Although similar factors were considered to be important for both reconstructive and aesthetic operations, only approximately 50 percent of respondents considered institutional review board approval to be an important factor when considering innovation in both reconstructive (50 percent) and aesthetic surgery (51 percent), suggesting that respondents do not consider innovation a form of research that ought be subject to standard research protections. Overall, the authors' survey suggests that more effort must be extended to ethical training in plastic surgery to create a stronger professional atmosphere regarding innovation and, possibly, to the creation of a more formal group charged with oversight of innovation.

OBJECTIVES/HYPOTHESIS/OBJECTIVE:Various animal models have been employed to investigate vocal fold (VF) and phonatory function. However, biomechanical testing techniques to characterize vocal fold structural properties vary and have not compared critical properties across species. We adapted a nondestructive, automated indentation mapping technique to simultaneously quantify VF structural properties (VF cover layer and intact VF) in commonly used species based on the hypothesis that VF biomechanical properties are largely preserved across species. STUDY DESIGN/METHODS:Ex vivo animal model. METHODS:Canine, leporine, and swine larynges (n = 4 each) were sagittally bisected, measured, and subjected to normal indentation mapping (indentation at 0.3 mm; 1.2 mm/s) with a 2-mm spherical indenter to quantify normal force along the VF cover layer, structural stiffness, and displacement at 0.8 mN; two-dimensional maps of the free VF edge through the conus elasticus were created for these characterizations. RESULTS:Structural stiffness was 7.79 gf/mm (0.15-74.55) for leporine, 2.48 gf/mm (0.20-41.75) for canine, and 1.45 gf (0.56-4.56) for swine. For each species, the lowest values were along the free VF edge (mean ± standard deviation; leporine: 0.40 ± 0.21 gf/mm, canine: 1.14 ± 0.49 gf/mm, swine: 0.89 ± 0.28 gf/mm). Similar results were obtained for the cover layer normal force at 0.3 mm. On the free VF edge, mean (standard deviation) displacement at 0.08 gf was 0.14 mm (0.05) in leporine, 0.11 mm (0.03) in canine, and 0.10 mm (0.02) in swine. CONCLUSIONS:Automated indentation mapping yielded reproducible biomechanical property measurement of the VF cover and intact VF. Divergent VF structural properties across canine, swine, and leporine species were observed. LEVEL OF EVIDENCE/METHODS:NA. Laryngoscope, 2018.

BACKGROUND:Masculinizing top surgery (bilateral mastectomy with chest wall reconstruction) is an important gender-affirming procedure sought by many transmasculine and non-binary individuals. Current literature is primarily focused on details of surgical technique and complication rates, with limited data available on how top surgery affects subjective quality of life measures. METHODS:An anonymous online survey was distributed to 81 of the senior author's former top surgery patients. Survey response rate was 72% (58 respondents). Responses were analyzed to investigate quality of life, sexual confidence, mental health, satisfaction with top surgery, and patient attitudes toward top surgery's role in gender affirmation. RESULTS:Following top surgery, measures of quality of life and sexual confidence significantly improved (P < .001). Additionally, 86% reported improvement in gender dysphoria-related mental health conditions. All but 1 respondent reported that top surgery had an overall positive impact on their life. CONCLUSIONS:Top surgery had major positive effects on all mental health and quality of life metrics. Our findings contribute to a much-needed body of evidence that top surgery markedly improves the daily lives and functioning of transgender and non-binary individuals who choose to undergo it.

BACKGROUND: Microvascular reconstruction of the lower extremity has the highest reported complication and flap failure rates of any anatomical region. Despite widespread adoption of the mechanical anastomotic venous coupler and encouraging results in other anatomical regions, there are limited reports examining its use in the lower extremity. This study compares outcomes between coupled and hand-sewn venous anastomoses in traumatic lower extremity reconstruction. METHODS:-tests. RESULTS: = 0.004). CONCLUSION/CONCLUSIONS: Complication and flap failure rates were similar between reconstructions performed with a venous coupler and those performed with hand-sewn venous anastomoses. These findings suggest that use of the venous anastomotic coupler is safe and effective in lower extremity reconstruction, with comparable outcomes to conventional sutured anastomoses.
