Article
A medical student describes a relationship with a cancer patient, the privilege of human connections in life, and the lessons learned from a first experience with death.
Article
Radiotherapy (RT) has become an indispensable part of oncologic treatment protocols for a range of malignancies. However, a serious adverse effect of RT is radiodermatitis; almost 95% of patients develop moderate to severe skin reactions following radiation treatment. In the acute setting, these can be erythema, desquamation, ulceration, and pain....

Radiation therapy can result in pathological fibrosis of healthy soft tissue. The iron chelator deferoxamine (DFO) has been shown to improve skin vascularization when injected into radiated tissue prior to fat grafting. Here, we evaluated whether topical DFO administration using a transdermal drug delivery system prior to and immediately following...

Significance Prevailing theory suggests that episodic memory encoding is subserved by early remodeling of hippocampal circuits, whereas remodeling of the neocortex occurs weeks to months later to promote long-term memory storage and recall. Herein, we show that episodic memory encoding elicits early remodeling of neocortical circuits in mouse brain...
Article
Background: The 2020-2021 residency application cycle marked the first year of fully virtual integrated plastic surgery interviews. The virtual format was a double-edged sword for applicants with several advantages such as reduced costs and time lost from travel and disadvantages as the novel format introduced new stressors on top of an already de...
Article
Background: The COVID-19 pandemic displaced medical students from their rotations and into virtual classrooms. We aimed to develop a virtual curriculum with the goals for students to gain knowledge in plastic surgery, to acquire technical skills, and to be able to promote community. Methods: We developed a four-week educational curriculum of top...
Article
Introduction: Striae distensae (SD) are common disfiguring cutaneous lesions but lack effective treatments due to an incomplete understanding of their pathophysiology. Dermal fibroblasts likely play an important role. We investigate the cellular-molecular features distinguishing fibroblasts from human SD and normal skin (NS). We also develop a mou...
Chapter
Adipose-derived stem cells (ASCs) can be isolated in large quantities from the lipoaspirates of patients. Furthermore, the therapeutic potential of ASCs is vast, with their ability to differentiate into osteogenic, chondrogenic, and adipogenic phenotypes. This chapter focuses on the genetic modifications of ASCs to differentiate into osteogenic cel...
Article
Background: In response to the cancellation of away rotations and the shift to virtual interviews due to the coronavirus disease of 2019 (COVID-19) pandemic, residency programs have pursued other methods of sharing program details, most notably with the use of social media. This study aimed to evaluate the extent of social media utilization in the...
Article
Objective: Xenografts of human skin on immunodeficient mice provide a means of assessing human skin physiology and its response to wounding. Approach: We describe a novel xenograft model using full-thickness human neonatal foreskin to examine human skin wound repair and fibroblast heterogeneity. Full-thickness 8-mm human neonatal foreskin biopsi...
Article
Pathologic skin scarring presents a vast economic and medical burden. Unfortunately, the molecular mechanisms underlying scar formation remain to be elucidated. We used a hypertrophic scarring (HTS) mouse model in which Jun is overexpressed globally or specifically in α-smooth muscle or collagen type I–expressing cells to cause excessive extracellu...
Article
Radiation therapy is effective for cancer treatment but may also result in collateral soft tissue contracture, contour deformities, and non-healing wounds. Autologous fat transfer has been described to improve tissue architecture and function of radiation-induced fibrosis and these effects may be augmented by enrichment with specific adipose-derive...
Article
Objective: Radiation therapy is commonplace for cancer treatment but often results in fibrosis and atrophy of surrounding soft tissue. Decellularized adipose matrices (DAMs) have been reported to improve these soft tissue defects through the promotion of adipogenesis. These matrices are decellularized by a combination of physical, chemical, and en...
Article
Interviews for the integrated plastic surgery residency match took place in a virtual format for the 2020-2021 application cycle. Current literature lacks the perspectives of program directors (PDs) on virtual interviews compared with traditional in-person interviews. Methods: Following institutional review board approval, an anonymous 17-questio...
Article
Regeneration without scarring Wounds in adult mammals typically heal by forming fibrotic scars. Mascharak et al. found that a specific population of skin fibroblasts ( Engrailed-1 lineage–negative fibroblasts) activate expression of Engrailed-1 and turn on profibrotic cellular programs in response to local tissue mechanics in wounds (see the Perspe...
Article
Full-text available
Fibroblast heterogeneity has been shown within the unwounded mouse dorsal dermis, with fibroblast subpopulations being identified according to anatomical location and embryonic lineage. Using lineage tracing, we demonstrate that paired related homeobox 1 (Prrx1)-expressing fibroblasts are responsible for acute and chronic fibroses in the ventral de...
Article
Atypical hyperplasia (AH) and lobular carcinoma in situ (LCIS) are markers for an increased risk of breast cancer, yet outcomes for these diagnoses are not well‐documented. In this study, all breast biopsies performed for radiologic abnormalities over a 10‐year period were reviewed. Patients with AH or LCIS were followed for an additional 10 years...
Article

Fibroblasts' integral role in tissue development, maintenance, and disease represents a fast-growing field of basic science research. Although fibroblasts were long thought to be a homogeneous cell population, recent research has illuminated the unforeseen complexity of these cells, giving rise to the rapidly expanding research field of "fibroblast...
Article
Full-text available
Fat grafting can reduce radiation-induced fibrosis. Improved outcomes are found when fat grafts are enriched with adipose-derived stromal cells (ASCs), implicating ASCs as key drivers of soft tissue regeneration. We have identified a subpopulation of ASCs positive for CD74 with enhanced antifibrotic effects. Compared to CD74- and unsorted (US) ASCs...
Article
Despite many breast cancer (BC) survivors turning to the internet for online health information (OHI)¹ and the American Medical Association recommending OHI written at the sixth-grade reading level to increase accessibility,² OHI quality and readability are variable.¹ Inaccurate or overly complex OHI can negatively affect patients’ care-seeking and...
Article
Full-text available
Fat grafting is a surgical technique able to reconstruct and regenerate soft tissue. The adipose-derived stromal cells (ASCs) within the stromal vascular fraction are believed to drive these beneficial effects. ASCs are increasingly recognized to be a heterogeneous group, comprised of multiple stem and progenitor subpopulations with distinct functi...
Article
Full-text available
Neonatal compartment syndrome is a rare condition. Early diagnosis and timely surgical intervention are paramount to optimize outcome. Time to fasciotomy is the most important prognostic factor. The purposes of this study were to describe a case presentation of neonatal compartment syndrome associated with a compound birth presentation and to perfo...
Article
Introduction Burns constitute a major health problem accounting together with fires for more than 300.000 deaths per year worldwide and for a great rate of disability-adjusted life years (DALYs). Identifying the relationship between mental disorders and burns is crucial since the former seems to constitute an important risk factor for the latter. A...
Article
The aim of this study was to explore the therapeutic effects of fat grafting on radiation-induced hind limb contracture. Radiation therapy (RT) is used to palliate and/or cure a range of malignancies but causes inevitable and progressive fibrosis of surrounding soft tissue. Pathological fibrosis may lead to painful contractures which limit movement...
Article
Background The prognostic significance of low-volume residual nodal disease following neoadjuvant chemotherapy (NAC) is unknown. Methods Women with cT1–4N0–1 breast cancer treated with NAC were identified from Dana-Farber/Brigham and Women’s Cancer Center (DFBWCC) and the National Cancer Database (NCDB). Disease-free survival (DFS) and overall sur...
Article
Introduction Surgical burns and fires related to the use of electrosurgery as a ‘‘Top 10 health technology hazard,’’ causing serious disfigurement or even death. These findings reveal a profound unmet need in the surgical community: surgeons and surgical trainees lack sufficient understanding of the appropriate and safe use of energy-based devices....
