The evidence justifying the use of acellular dermal matrices (ADMs) in implant-based breast reconstruction (IBBR) is limited. We did a prospective randomised trial to compare the safety of IBBR with an ADM immediately after mastectomy with that of two-stage IBBR.
We did an open-label, randomised, controlled trial in eight hospitals in the Netherlands. Eligible women were older than 18 years with breast carcinoma or a gene mutation linked with breast cancer who intended to undergo skin-sparing mastectomy and immediate IBBR. Randomisation was done electronically, stratified per centre and in blocks of ten to achieve roughly balanced groups. Women were assigned to undergo one-stage IBBR with ADM (Strattice, LifeCell, Branchburg, NJ, USA) or two-stage IBBR. The primary endpoint was quality of life and safety was assessed by the occurrence of adverse outcomes. Analyses were done per protocol with logistic regression and generalised estimating equations. This study is registered at Nederlands Trial Register, number NTR5446.
142 women were enrolled between April 14, 2013, and May 29, 2015, of whom 59 (91 breasts) in the one-stage IBBR with ADM group and 62 (92 breasts) in the two-stage IBBR group were included in analyses. One-stage IBBR with ADM was associated with significantly higher risk per breast of surgical complications (crude odds ratio 3·81, 95% CI 2·67–5·43, p<0·001), reoperation (3·38, 2·10–5·45, p<0·001), and removal of implant, ADM, or both (8·80, 8·24–9·40, p<0·001) than two-stage IBBR. Severe (grade 3) adverse events occurred in 26 (29%) of 91 breasts in the one-stage IBBR with ADM group and in five (5%) of 92 in the two-stage IBBR group. The frequency of mild to moderate adverse events was similar in the two groups.
Immediate one-stage IBBR with ADM was associated with adverse events and should be considered very carefully. Understanding of selection of patients, risk factors, and surgical and postsurgical procedures needs to be improved.

There is increasing interest in the use of acellular dermal matrices (ADMs) in implant-based breast reconstruction (IBBR). Suggested advantages are that ADMs facilitate one-stage IBBR and improve aesthetic outcomes. We compared immediate one-stage ADM-assisted IBBR with two-stage IBBR (current standard of care). Our previously reported secondary endpoint showed that one-stage ADM-assisted IBBR was associated with significantly more adverse outcomes. Here, we present the primary endpoint results aiming to assess whether one-stage IBBR with ADM provides higher patient-reported quality of life (QOL) compared with two-stage IBBR.
This multicentre, open-label, randomised controlled trial (BRIOS study) was done in eight hospitals in the Netherlands. We recruited women aged older than 18 years with breast carcinoma or a genetic predisposition who intended to undergo skin-sparing mastectomy and immediate IBBR. Participants were randomly assigned to undergo one-stage IBBR with ADM (Strattice, LifeCell, Branchburg, NJ, USA) or two-stage IBBR. Randomisation was stratified by centre and indication for surgery (oncological or prophylactic) in blocks of ten participants. The primary endpoint was patient-reported QOL, as measured with the BREAST-Q (ie, health-related QOL scales and satisfaction scales), in the modified intention-to-treat population. The study follow-up is complete. This study is registered with the Netherlands Trial Register, number NTR5446.
Between April 14, 2013, and May 29, 2015, we enrolled 142 women, of whom 69 were randomly assigned to receive one-stage ADM-assisted IBBR and 73 to receive two-stage IBBR. After exclusions, the modified intention-to-treat population comprised 60 patients in the one-stage group and 61 patients in the two-stage group. Of these, 48 women (mean follow-up 17·0 months [SD 7·8]) in the one-stage group and 44 women (17·2 months [SD 6·7]) in the two-stage group completed the BREAST-Q at least 1 year after implant placement. We found no significant differences in postoperative patient-reported QOL domains, including physical wellbeing (one-stage mean 78·0 [SD 14·1] vs two-stage 79·3 [12·2], p=0·60), psychosocial wellbeing (72·6 [17·3] vs 72·8 [19·6], p=0·95), and sexual wellbeing (58·0 [17·0] vs 57·1 [19·5], p=0·82), or in the patient-reported satisfaction domains: satisfaction with breasts (63·4 [15·8] vs 60·3 [15·4], p=0·35) and satisfaction with outcome (72·8 [19·1] vs 67·8 [16·3], p=0·19).
Taken together with our previously published findings, one-stage IBBR with ADM does not yield superior results in terms of patient-reported QOL compared with two-stage IBBR. Risks for adverse outcomes were significantly higher in the one-stage ADM group. Use of ADM for one-stage IBBM should be considered on a case-by-case basis.

fibrodysplasia ossificans progresssiva
2022
Fibrodysplasia ossificans progressiva (FOP), sometimes known as myositis ossificans progressiva, is an ultra-rare disease in which bone is formed in muscular tissue, tendons and ligaments. This is known as heterotopic ossification (HO). FOP is caused by a heterozygous mutation in the highly conserved ACVR1/ALK2 gene which affects about 1 in 1.5-2 million individuals. At birth, patients with the predominant R206H mutation only exhibit a bilateral hallux valgus. During childhood, heterotopic bone formation develops in a typical pattern, affecting the axial muscles first before appendicular body parts are involved. HO can start spontaneously but is often elicited by soft tissue trauma or medical procedures. After soft tissue injury, an inflammatory process called a flare-up can start, followed by the formation of HO. HO leads to a limited range of motion, culminating in complete ankylosis of nearly all joints. As a result of HO surrounding the thorax, patients often suffer from thoracic insufficiency syndrome (TIS). TIS is the most common cause of a limited life expectancy for FOP patients, with a median life expectancy of 56 years. Management is focused on preventing soft-tissue injury that can provoke flare-ups. This includes prevention of iatrogenic damage by biopsies, intramuscular injections and surgery. Anti-inflammatory medication is often started when a flare-up occurs but has a poor basis of evidence. Several forms of potential treatment for FOP are being researched in clinical trials. Progression of the disease is monitored using CT and 18F-NaF PET/CT combined with functional assessments. Patients are regularly evaluated for frequently occurring complications such as restrictive lung disease. Here, we review the current management, monitoring and treatment of FOP.

IntroductionPioneers have shown that it is possible to reconstruct a full breast using just autologous fat harvested by liposuction or autologous fat transfer (AFT). This study describes the first multicentre randomised study protocol to thoroughly investigate the effectiveness of AFT to reconstruct full breasts following mastectomy procedures (primarily and delayed).Methods and analysisThis study is designed as a multicentre, randomised controlled clinical superiority trial with a 1:1 allocation ratio. A total of 196 patients (98 patients per treatment arm) are aimed to be included. Patients who wish to undergo breast reconstruction with either one of the two techniques are randomly allocated into the AFT group (intervention) or the tissue-expander/prosthesis group (control). The primary outcome measure for the quality of life is measured by the validated BREAST-Q questionnaire.Ethics and disseminationApproval for this study was obtained from the medical ethics committee of Maastricht University Medical Centre/Maastricht University; the trial has been registered at ClinicalTrials.gov. The results of this randomised controlled trial will be presented at scientific meetings as abstracts for poster or oral presentations and published in peer-reviewed journals.Trial statusEnrolment into the trial has started in October 2015. Data collection and data analysis are expected to be completed in December 2021.Trial registration numberNCT02339779.

Abstract
Context
Breast development is important for most trans women. An important limitation of current breast development measurement methods is that these do not allow for 3D volume analyses.
Objectives
To examine breast development and change in anthropometry during the first 3 years of gender-affirming hormone treatment using 3D imaging. Associations with clinical or laboratory parameters and satisfaction with the gained breast development were also studied.
Design
Prospective cohort study.
Setting
Specialized tertiary gender identity clinic in Amsterdam, the Netherlands.
Participants
Participants were 69 adult trans women with a median age of 26 years (interquartile range, 21-38).
Interventions
Gender-affirming hormone treatment.
Main Outcome Measures
Volumetric and anthropometric breast development and satisfaction.
Results
Breast volume increased by 72 cc (95% confidence interval [CI], 48-97) to 100 cc (standard deviation 48). This resulted in a cup-size

Three-dimensional (3D) imaging techniques are promising new tools for measuring breast volume, for example in gender-affirming therapy. Transgender individuals can be treated with gender-affirming hormone therapy (GAHT). A robust method for monitoring breast volume changes is critical to be able to study the effects of feminizing GAHT. The primary aim of this study was to compare the accuracy of three 3D devices (Vectra XT, Artec LEO and iPhone XR) for measuring modest breast volume differences using a mannequin. The secondary aim of this study was to evaluate these methods in several performance domains. We used reference prostheses of increasing volumes and compared the volumes using GOM-inspect software. For Vectra XT 3D images, manufacturer-provided software was used to calculate volumes as well. The scanning methods were ranked based on their performance in a total of five categories: volume estimations, costs, user-friendliness, test subject-friendliness and technical aspects. The 3D models analyzed with GOM-inspect showed relative mean estimate differences from the actual volumes of 9.1% for the Vectra XT, 7.3% for the Artec LEO and 14% for the iPhone XR. For the Vectra XT models analyzed with the built-in software this was 6.2%. Root mean squared errors (RMSE) calculated based on the GOM-inspect volume analyses showed mean RMSEs of 2.27, 2.54 and 8.93 for the Vectra XT, Artec LEO and iPhone XR, respectively. The Vectra software had a mean RMSE of 3.00. In the combined performance ranking, the Vectra XT had the most favorable ranking, followed by the Artec LEO and the iPhone XR. The Vectra XT and Artec LEO are the preferred scanners to monitor breast development due to the combination of higher accuracy and overall performance. The current study shows that 3D techniques can be used to adequately measure modest breast volume differences and therefore will be useful to study for example breast changes in transgender individuals using feminizing GAHT. These observations may also be relevant in other fields of 3D imaging research.

Osteogenesis Imperfecta (OI), known as “brittle bone disease,” presents a rare genetic disorder characterized by bone fragility, often accompanied by skeletal deformities and extraskeletal complications. OI is primarily associated with collagen type I defects, responsible for the syndromic nature of the disease affecting a broad range of tissues. As such, its multisystemic complexity necessitates multidisciplinary care approaches in all patient life stages. OI treatment remains largely supportive, commonly including bisphosphonates and orthopedic surgeries, which show promise in children. Although rehabilitation programs for children exist, guidelines for adult care and especially the transition from pediatric to adult care, are lagging behind in OI care and research. The current systematic review summarizes the literature on OI patient pediatric to adult care transition experiences and compares OI transition approaches to other chronic diseases. The review was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Systematic searches were conducted across multiple databases. Search terms encompassed synonyms and closely related phrases relevant to “OI” and “Transition to adult care”. The initial screening involved the evaluation of article titles, followed by a thorough review of abstracts to assess relevance for the purpose of the current review. Programs aimed at easing the transition from pediatric to adult OI care necessitate a multifaceted approach. Collaborative efforts between different medical disciplines including pediatricians, endocrinologists, orthopedics, cardiology, pulmonology, ophthalmology, otolaryngologists, maxillofacial specialists, psychologists and medical genetics, are crucial for addressing the diverse needs of OI patients during this critical life phase. Comprehensive education, readiness assessments, personalized transition plans, and further follow-up are essential components of a structured transition framework. Further research is warranted to evaluate the feasibility and efficacy of sequential stepwise transition systems tailored to individuals with OI.

Background
Autologous fat transfer (AFT) seems to be a new minimal invasive method for total breast reconstruction, yet how patients, surgeons, and laymen evaluate cosmesis is lacking. The aim of this study was to evaluate the aesthetic outcome of AFT (intervention group) for total breast reconstruction post-mastectomy, as compared to implant-based reconstruction (IBR) (control group).
Methods
A random and blinded 3D photographic aesthetic outcome study was performed on a selection of 50 patients, scored by three panels: plastic surgeons, breast cancer patients, and laymen. Secondary outcomes included agreement within groups and possible patient characteristics influencing scoring.
Results
Breast cancer patients and plastic surgeons did not differ in the aesthetic scores between the treatment groups. In contrast, the laymen group scored AFT patients lower than IBR patients (− 1.04,
p
< 0.001). Remarkably, mean given scores were low for all groups and overall agreement within groups was poor (ICC < 0.50). Higher scores were given when subjects underwent a bilateral reconstruction and if a mamilla was present.
Conclusion
Evaluation of aesthetic outcomes varies greatly. Hence, aesthetic outcome remains a very personal measure and this emphasizes the importance of thorough patient counseling including information on achievable aesthetic results before starting a reconstructive procedure.

Background:
Vaginoplasty is performed as gender-affirming surgery in transgender women. While multiple surgical techniques exist for this goal, penile inversion vaginoplasty is performed most frequently. Neovaginal symptoms may impede sexual functioning after surgery.
Methods:
A total of five consecutive patients with symptoms and positive swabs for neovaginal candida infection were described.
Results:
All patients presented with white-colored neovaginal discharge and some with neovaginal itching and/or malodor. All were topically treated with miconazole, which resulted in symptom clearance. Follow-up swabs were negative for candida.
Conclusions:
To our knowledge, this is the first report on (symptomatic) candidiasis of the penile-inverted neovagina.
