Critical traumatic brain injury is associated with worse coagulopathy.

Objectives: As thromboelastography (TEG) becomes the standard of care in patients with hemorrhagic shock (HS), an association between concomitant traumatic brain injury (TBI) and coagulopathy by TEG parameters is not well understood and is thus investigated.

Methods: Retrospective analysis of trauma registry data at a single level 1 trauma center of 772 patients admitted with head Abbreviated Injury Scale (AIS) score of 3 and TEG studies between 2014 and 2017. Patients were stratified to moderate-severe TBI by head AIS scores of 3 and 4 (435 patients) and critical TBI by head AIS score of 5 (328 patients).

Effects of sleepiness on clinical decision making among paramedic students: a simulated night shift study.

Objective: Paramedics are at the forefront of emergency healthcare. Quick and careful decision making is required to effectively care for their patients; however, excessive sleepiness has the potential to impact on clinical decision making. Studies investigating the effects of night shift work on sleepiness, cognitive function and clinical performance in the prehospital setting are limited.

Clinical Determinants of Dual Tasking in People With Premanifest Huntington Disease.

Objective: Dual-tasking deficiencies are common in people with Huntington disease (HD) and contribute to reduced functional independence. To date, few studies have investigated the determinants of dual-tasking deficiencies in this population. The reliability of dual-tasking measures has also been poorly investigated in HD.

Dual tasking impairments are associated with striatal pathology in Huntington's disease.

Background: Recent findings suggest that individuals with Huntington's disease (HD) have an impaired capacity to execute cognitive and motor tasks simultaneously, or dual task, which gradually worsens as the disease advances. The onset and neuropathological changes mediating impairments in dual tasking in individuals with HD are unclear. The reliability of dual tasking assessments for individuals with HD is also unclear.

The effects of multidisciplinary rehabilitation on neuroimaging, biological, cognitive and motor outcomes in individuals with premanifest Huntington's disease.

Background: Huntington's disease (HD) is a chronic, progressive neurodegenerative condition for which there are currently no proven disease-modifying therapies. Lifestyle factors have been shown to impact on the age of disease onset and progression of disease features. We therefore investigated the effects of a nine-month multidisciplinary rehabilitation intervention on neuroimaging, biological and clinical disease outcomes in individuals with premanifest HD.

Comparative Antimicrobial Activity of Commercial Wound Care Solutions on Bacterial and Fungal Biofilms.

Background: Biofilms represent a complex milieu of matrix-enclosed microorganisms, which can significantly contribute to the pathology of chronic wounds. In this study, we compare the activity of 3 commercial antimicrobial wound care solutions, Vashe (HOCl based), PhaseOne (HOCl based), and Sulfamylon (mafenide acetate), for their in vitro activity against bacterial and fungal biofilms.

Methods: Reference and clinical isolates of 6 Gram-negative bacterial species (36 total strains), 3 Gram-positive bacteria (21 strains), and 3 Candida species (9 strains) were used to create biofilms.

Reducing Expansion Visits in Immediate Implant-Based Breast Reconstruction: A Comparative Study of Prepectoral and Subpectoral Expander Placement.

Background: The numerous office visits required to complete expansion in implant-based breast reconstruction impact patient satisfaction, office resources, and time to complete reconstruction. This study aimed to determine whether prepectoral compared to subpectoral immediate implant-based breast reconstruction offers expedited tissue expansion without affecting complication rates.

Methods: Consecutive patients who underwent immediate implant-based breast reconstruction with tissue expanders from January of 2016 to July of 2017 by a single surgeon were grouped into subpectoral (partial submuscular/partial acellular dermal matrix) or prepectoral (complete acellular dermal matrix coverage), and reviewed.

Quadruple Perforator Flaps for Primary Closure of Large Myelomeningoceles: An Evaluation of the Butterfly Flap Technique.

Introduction: Myelomeningocele is the most common open neural tube defect. A quadruple rotation-VY advancement flap (butterfly flap) was recently reported for closure of large myelomeningocele defects; however, no series has been reproduced to evaluate this technique. The objective of this study was to describe our experience with this technique.

Diffusion tensor tractography to visualize axonal outgrowth and regeneration in a 4-cm reverse autograft sciatic nerve rabbit injury model.

Background: Diffusion tensor tractography (DTT) has recently been shown to accurately detect nerve injury and regeneration. This study assesses whether 7-tesla (7T) DTT imaging is a viable modality to observe axonal outgrowth in a 4 cm rabbit sciatic nerve injury model fixed by a reverse autograft (RA) surgical technique.

Methods: Transection injury of unilateral sciatic nerve (4 cm long) was performed in 25 rabbits and repaired using a RA surgical technique.

Does Brow Lift Add Risk to Blepharoplasty? Answers From a Multicenter Analysis of 6126 Patients Undergoing Aesthetic Eye Surgery.

Background: Browlift is frequently combinedwith blepharoplasty; however, the literature is lacking on their combined effect on complication rates.

Objectives: This study aims to evaluate major complication rates after blepharoplasty and brow lift and to determine if complication rates increase when blepharoplasty and brow lift were performed simultaneously.

Methods: A prospective cohort of patients who underwent cosmetic blepharoplasty, brow lift, or a combination of the 2 procedures between 2008 and 2013 was identified from the CosmetAssure Insurance database.

Image once, print thrice? Three-dimensional printing of replacement parts.

Objective: The last 20 years has seen an exponential increase in 3D printing as it pertains to the medical industry and more specifically surgery. Previous reviews in this domain have chosen to focus on applications within a specific field. To our knowledge, none have evaluated the broad applications of patient-specific or digital imaging and communications in medicine (DICOM) derived applications of this technology.

Plantar Fat Grafting and Tendon Balancing for the Diabetic Foot Ulcer in Remission.

We report on the use of free fat grafting as a means of redistributing normal and shear stress after healing of plantar diabetic foot wounds. Although fat augmentation (lipofilling) has been described previously as an approach to supplement defects and prevent atrophy, including use as an adjunct to wound healing and to mitigate pain in the foot, we are unaware of any reports in the medical literature that have described its use in the high-risk diabetic foot in remission. An active 37-year-old man with type 2 diabetes and neuropathy presented with gangrene of his fifth ray, which was amputated.

Illustration of Cost Saving Implications of Lower Extremity Nerve Decompression to Prevent Recurrence of Diabetic Foot Ulceration.

The US diabetic foot ulcer (DFU) incidence is 3-4% of 22.3 million diagnosed diabetes cases plus 6.3 million undiagnosed, 858 000 cases total.

Early two-stage repair of clefts in holoprosencephaly.

Unlabelled: Holoprosencephaly (HPE) presents with a spectrum of severity, but in its totality is the most common malformation of the embryonic forebrain occurring 1 in 10,000 to 1 in 20,000 live births. Due to the poor prognosis, treatment of mid-face clefts in HPE patients have classically been addressed in a delayed fashion after 1-year of age. Improvements in the ability to manage medical complications associated with HPE along with an increased understanding and lower mortality rates in less severe forms have challenged these previous practiced routines.

Palliative reconstructive surgery may improve quality of life in high functioning noncurable head and neck oncologic patients.

Background: Treatment recommendations for palliative patients are guided by functional status and individual needs. The projected success of palliative procedures relies on estimating the risk: benefit ratio, which weighs the expected improvement in life quality to the frailty, metabolic status, and the individual's ability to heal after surgery. Terminal patients have less time in which to judge outcomes; therefore, the timeframe in which we assess these metrics should be modified according to prognosis.

Reduction of pain via platelet-rich plasma in split-thickness skin graft donor sites: a series of matched pairs.

In the past decade, autologous platelet-rich plasma (PRP) therapy has seen increasingly widespread integration into medical specialties. PRP application is known to accelerate wound epithelialization rates, and may also reduce postoperative wound site pain. Recently, we observed an increase in patient satisfaction following PRP gel (Angel, Cytomedix, Rockville, MD) application to split-thickness skin graft (STSG) donor sites.

A passing glance? Differences in eye tracking and gaze patterns between trainees and experts reading plain film bunion radiographs.

Eye tracking and gaze pattern studies have been used to evaluate human behavior for decades. This is because of its ability to reveal conscious and subconscious behaviors when subjects are tasked with observation, decision making, and surgical performance. Many have popularized the use of this technology for radiographic assessment while evaluating radiologist behaviors, but little has been described for surgeon behavior patterns when evaluating preoperative deformities by radiograph.

A heads-up display for diabetic limb salvage surgery: a view through the google looking glass.

Although the use of augmented reality has been well described over the past several years, available devices suffer from high cost, an uncomfortable form factor, suboptimal battery life, and lack an app-based developer ecosystem. This article describes the potential use of a novel, consumer-based, wearable device to assist surgeons in real time during limb preservation surgery and clinical consultation. Using routine intraoperative, clinical, and educational case examples, we describe the use of a wearable augmented reality device (Google Glass; Google, Mountain View, CA).

Three-dimensional printing surgical instruments: are we there yet?

Background: The applications for rapid prototyping have expanded dramatically over the last 20 y. In recent years, additive manufacturing has been intensely investigated for surgical implants, tissue scaffolds, and organs. There is, however, scant literature to date that has investigated the viability of three-dimensional (3D) printing of surgical instruments.
