There is a renewed interest for prepectoral reconstruction. We aimed to describe the feasibility and the early complications associated with immediate one-stage direct-to-implant (DTI) reconstruction using prepectoral anatomical polyurethane (PU) foam-coated implants alone, for women with breast cancer or mutation carriers undergoing risk-reducing surgery.

We performed a single-center, retrospective review of 50 patients (mean age of 49 years), who underwent skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) and immediate prepectoral PU implant-based reconstruction. All procedures were performed by the same senior operator, from July 2018 to March 2020.

A total of 64 mastectomies (25 SSMs and 39 NSMs) with one-stage prepectoral PU foam-coated implant reconstruction were performed. Out of 50 patients, 6 required surgical revision within 30 days, because of hematoma (2), wound dehiscence (2) infection (1), and full thickness nipple-areolar complex (NAC) necrosis (1). Four patients developed ccording to preoperative lower breast measurements.
Accurate mapping of perforators prior to flap reconstruction and early detection of poor flap perfusion reduces the risk of flap failure. Infrared thermography (IRT) has recently regained popularity within reconstructive surgery to aid flap design, reduce operative time and assess flap viability based on surface temperature changes. The aim of this review is to quantify the diagnostic ability of IRT in perforator mapping preoperatively and monitor flap perfusion perioperatively.

We conducted a systematic review of literature and included all studies that evaluated the use of IRT for perforator mapping and flap perfusion monitoring. We used a mixed-effects logistic regression bivariate model to estimate the summary sensitivity and specificity and constructed hierarchical summary receiver operative characteristic (HSROC) curves.

We identified 18 studies and observed IRT to have sensitivities of 99.6% and 89.6% with specificities of 99.9% and 96.0% for perforator mapping and flap monitoring, respectively. Moreover, IRT recognises patterns of perfusion within interperforator zones through visualisation of angiosomal rewarming and may improve flap outcomes.

Studies in the literature have demonstrated the presence of sex hormone receptors in infantile hemangiomas (IHs), but further investigation is needed to determine the role of these receptors in their proliferation and involution. To date, there are no studies in the literature that aimed to quantitatively examine the expression of sex hormone receptors throughout the different phases of hemangioma development.

The objective of our study was to quantitatively evaluate the expression of estrogen (ER) and progesterone (PR) receptors in the proliferative and involuting phases of IHs through the use of real-time polymerase chain reaction (RT-PCR).

Twenty IHs (10 proliferating and 10 involuting) were harvested and prepared for molecular investigation. NSC167409 ER receptor alpha (ERα) and beta (ERβ) and the PR expression were examined by RT-PCR and western blot.

RT-PCR analysis demonstrated that mRNA expression of ERα, ERβ, and PR was significantly lower in proliferating versus involuting IH. Western blot analysis revealed increased protein expression of ERα in involuting hemangiomas as compared to proliferating ones.

Our study demonstrates the variable expression of ER and PR receptors in proliferating and involuting hemangiomas. Further studies are needed to determine the exact role of these hormone receptors in the growth and involution of IHs.

This report presents the medial pillar island flap technique of oncoplastic breast reconstruction of central defects that involve the nipple-areola complex.

The procedure was performed in patients who presented with inferior pole redundancy using a vertical mammaplasty pattern. The flap was designed utilizing the territory of the lower pole as an island flap pedicled by the internal mammary artery perforators surrounded by the soft tissue of the medial pillar.

Eight patients underwent the procedure with a mean age of 57.6 years. Median breast cup size was D (range from C to DDD). The mean body mass index was 37.3 kg/m
(range from 32.1 to 41.5). The size of the defect ranged from 64 to 150 cm
(mean, 97.2). Concomitant opposite breast vertical reduction was performed in 6 cases. Flap survival was uneventful. Nipple reconstruction was performed 6 months after radiation treatment in 4 patients. No major complications were encountered. Two patients developed minor wound breakdown after nipple reconstruct which results in a smooth contour to the lower pole. The flap allows for nipple reconstruction using well-vascularized skin paddle. The technique is offered as an alternative oncoplasty option for neoareolar reconstruction.
There is a high incidence of performance-related musculoskeletal disorders in musicians that may be reduced via education programs. However, the efficacy of formalized injury prevention programs has not been rigorously studied.

To assess the feasibility and effect of a formalized injury prevention education workshop on incidence and severity of musculoskeletal pain in a cohort of musician-students attending an intensive summer music festival compared to controls.

Randomized-controlled-pilot trial.

Musicians at an 8-week long intensive summer festival were randomized to an intervention (workshop) or control group. Workshop attendees participated in a 90-minute session of injury prevention strategies. Musculoskeletal outcome data were collected at the start and end of the festival. Outcomes included presence of musculoskeletal pain, adherence level, and sub-scales of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians.

A total of 57 musician-students (ages 17-30, 23 females) participated in the study, and 48(84%) completed the study.
