Spontaneous remyelination occurs after spinal cord injury (SCI), but the extent of myelin repair and identity of the cells responsible remain incompletely understood and contentious. We assessed the cellular origin of new myelin by fate mapping PDGFRα+, Olig2+, and P0+ cells following contusion SCI in mice. Oligodendrocyte precursor cells (OPCs; PDGFRα+) produced oligodendrocytes responsible for de novo ensheathment of ∼30% of myelinated spinal axons at injury epicenter three months after SCI, demonstrating that these resident cells are a major contributor to oligodendrocyte regeneration...

BACKGROUND: Acute upper extremity injuries remain one of the most common consultations in the emergency departments for plastic surgery services. These injuries can affect a person's quality of life and negatively affect work-related or social interactions if not properly managed. We aim to evaluate our experience and management in a specialized referral center in Mexico City. METHODS: A retrospective review was performed. All patients with hand trauma managed by our service from July 2010 to June 2015 were included; their demographic characteristics were described as well as the most common patterns of injury, management, and outcome...

OBJECTIVE: It is believed that spending additional years gaining expertise in surgical subspecialization leads to higher lifetime revenue. Literature shows that more surgeons are pursuing fellowship training and dedicated research years; however, there are no data looking at the aggregate economic impact when training time is accounted for. It is hypothesized that there will be a discrepancy in lifetime income when delay to practice is considered. DESIGN: Data were collected from the Medical Group Management Association's 2015 report of average annual salaries...

Surgical management of soft-tissue defects of the forefoot and midfoot caused by trauma or diabetic complications can be challenging because locoregional tissue is insufficient to provide adequate flap. This deficiency necessitates higher-level amputations, such as Chopart or even transtibial amputation, resulting in far more debilitating functional outcomes than are seen with partial foot amputation. The purpose of this study was to examine the surgical outcomes after transmetatarsal amputation and a free-flap transfer to preserve foot length...

BACKGROUND: The BDNF gene codes for brain-derived neurotrophic factor, a growth factor involved in neural development, cell differentiation, and synaptic plasticity. Present in both the brain and periphery, BDNF plays critical roles throughout the body and is essential for placental and fetal development. Rodent studies show that early life stress, including prenatal stress, broadly alters BDNF methylation, with presumed changes in gene expression. No studies have assessed prenatal exposure to maternal traumatic stress and BDNF methylation in humans...

Acute health care environments can be stressful settings with clinicians experiencing deleterious effects of burnout and compassion fatigue affecting their mental health. Subsequently, the quality of patient care and outcomes may be threatened if clinicians experience burnout or compassion fatigue. Therefore, the aim of this descriptive, cross-sectional study was to evaluate the prevalence of burnout and compassion fatigue among burn clinicians in Israel. Fifty-five clinicians from Burns, Plastics and Reconstruction Surgery and Intensive Care completed four validated surveys to assess burnout (Maslach Burnout Inventory), depression (PRIME-MD), health-related quality of life (SF-8), and compassion fatigue (Professional Quality of Life version 5)...

Exposure to excessive or uncontrolled stress is a major factor associated with various diseases including posttraumatic stress disorder (PTSD). The consequences of exposure to trauma are affected not only by aspects of the event itself, but also by the frequency and severity of trauma reminders. It was suggested that in PTSD, hippocampal-dependent memory is compromised while amygdala-dependent memory is strengthened. Several lines of evidence support the role of the endocannabinoid (eCB) system as a modulator of the stress response...

Minimal traumatic brain injury (MTBI) often transforms into chronic neuropsychiatric conditions including anxiety, the underlying mechanisms of which are largely unknown. In the present study, we employed the closed-head injury paradigm to induce MTBI in rats and examined whether DNA methylation can explain long-term changes in the expression of the brain-derived neurotrophic factor (BDNF) in the amygdala as well as trauma-induced anxiety-like behaviors. The MTBI caused anxiety-like behaviors and altered the expression of DNA methyltransferase (DNMT) isoforms (DNMT1, DNMT3a, and DNMT3b) and factors involved in DNA demethylation such as the growth arrest and DNA damage 45 (GADD45a and GADD45b)...

Autologous microsurgical flap reconstruction has become commonplace in most plastic surgery units, and the success rates of this procedure have markedly increased over recent years. However, the possibility of flap failure still needs to be considered. A review of the literature reveals that the critical period for flap-threatening complications is the first 24-48 post-operative hours; however, the window for the onset of these complications remains open for up to 7 days post-operatively. In this study, we focus on the timing of flap complications, aiming to elucidate the time period over which meticulous flap monitoring can positively contribute to flap salvage rates...

BACKGROUND: Electrical burns are quite different from thermal and chemical burns. This study is from a centre which deals with job related electric burn injuries alone and thus can give a pure account of the electric burns and discuss the related peculiarities. Study aims to highlight the differences in the mechanism of electric burn injury, its mode of presentation, morbidity, complications and thus the treatment strategies as compared to rest of the burn injuries. METHODS: This is a descriptive case series study of first consecutive 61 electric burn victims treated at a Burn Unit and Plastic Surgery centre...

This paper describes a method used for the fabrication of a two-piece denture obturator for a patient who had surgical removal of the premaxilla due to squamous cell carcinoma. The patient had been wearing a two-piece obturator but encountered difficulty in inserting the prosthesis. In this case report, a lock-and-key mechanism was used to easily assemble the two-piece prosthesis intraorally. A keyhole was designed on the obturator to act as the lock while the denture was used as the key that fitted into the keyhole...

Traumatic scalp and forehead injuries are frequently encountered in the acute setting in Level I trauma centers. This is a Level IV Therapeutic/Care Management article describing a retrospective review that analyzed a single Plastic and Reconstructive surgeon's experience treating these injuries in patients, over an 8-year period from 2006 to 2014. Fewer complications were seen in patients treated within 7 days of injury. When treating these patients, a surgeon should possess several key attributes. The ability to perform adequate primary debridement, knowledge, and familiarity with the intricate anatomy in this region, and experience with simple and complex reconstructive algorithms-are all crucial to obtaining optimal functional and aesthetic outcomes in this anatomic region...

A social-stress mouse model was used to simulate features of post-traumatic stress disorder (PTSD). The model involved exposure of an intruder (male C57BL/6) mouse to a resident aggressor (male SJL) mouse for 5 or 10 consecutive days. Transcriptome changes in brain regions (hippocampus, amygdala, medial prefrontal cortex and hemibrain), blood and spleen as well as epigenome changes in the hemibrain were assayed after 1- and 10-day intervals following the 5-day trauma or after 1- and 42-day intervals following the 10-day trauma...

REVIEW
Hagit Cohen, Zeev Kaplan, Joseph Zohar
Glucocorticoids (GCs) play a major role in orchestrating the complex physiological and behavioral reactions essential for the maintenance of homeostasis. These compounds enable the organism to prepare for, respond to and cope with the acute demands of physical and emotional stressors. The appropriate GC release, commensurate with stressor severity, enables the body to properly contain stress responses so as to promote recovery by rapidly restoring homeostasis. Indeed, inadequate GC release following stress not only delays recovery by disrupting biological homeostasis in the short run but can also interfere with the processing or interpretation of stressful information that results in long-term disruptions in memory integration...

BACKGROUND: Heel reconstruction represents a challenge for all plastic surgeons due to the anatomical and functional features of this weight-bearing area. In the last decade a combined use of acellular dermal matrices and skin grafts has been proposed as a reliable and less invasive alternative for complex wound management; nevertheless only a few cases have been reported in the literature. METHODS: We describe the long-term outcome of 2 cases of severe degloving trauma of the plantar region with massive soft tissue defects of the foot, that underwent surgical reconstruction with artificial dermis and skin grafts...

Traumatic brain injury (TBI) is a major cause of morbidity and mortality among young individuals worldwide. Understanding the pathophysiology of neurotrauma is crucial for the development of more effective therapeutic strategies. After the trauma occurs, immediate neurologic damage is produced by the traumatic forces; this primary injury triggers a secondary wave of biochemical cascades together with metabolic and cellular changes, called secondary neural injury. In the scenario of the acutely injured brain, the ongoing secondary injury results in ischemia and edema culminating in an uncontrollable increase in intracranial pressure...
