Infection after penetrating brain injury-An Eastern Association for the Surgery of Trauma multicenter study oral presentation at the 32nd annual meeting of the Eastern Association for the Surgery of Trauma, January 15-19, 2019, in Austin, Texas.

Background: Fatality rates following penetrating traumatic brain injury (pTBI) are extremely high and survivors are often left with significant disability. Infection following pTBI is associated with worse morbidity. The modern rates of central nervous system infections (INF) in civilian survivors are unknown.

Heart transplantation in two adolescents with Danon disease.

Danon disease (DD) is an X-linked dominant disorder caused by a mutation in the lysosomal-associated membrane protein-2 (LAMP-2) gene coding for the LAMP-2 protein. We report two cases of successful heart transplantation (HT) in adolescent brothers with DD, including one who was bridged to HT for 34 days with a HeartWare left ventricular assist device. In both patients, the post-transplant course was complicated by profound skeletal muscle weakness that resolved with corticosteroid withdrawal.

Adults with Philadelphia Chromosome-Like Acute Lymphoblastic Leukemia: Considerations for Allogeneic Hematopoietic Cell Transplantation in First Complete Remission.

Philadelphia chromosome-like (Ph-like) acute lymphoblastic leukemia (ALL) is a subset of high-risk B cell ALLs. A large proportion of Ph-like ALL cases carry activating kinase mutations that could potentially allow them to be targeted by tyrosine kinase inhibitors. Ph-like ALL is not an uncommon entity, especially among adults, with a frequency exceeding 20%, including in older patients (>60 years old) with ALL.

Prevention of Tracheostomy-Related Hospital-Acquired Pressure Ulcers.

Objective To determine if standardization of perioperative tracheostomy care procedures decreased the incidence of hospital-acquired tracheostomy-related pressure ulcers. Methods All patients at least 18 years old who underwent placement of a tracheostomy tube in the operating room from July 1, 2014, through June 30, 2015, were cared for postoperatively through an institutionally adopted quality improvement protocol. This included 4 elements: (1) placement of a hydrocolloid dressing underneath the tracheostomy flange in the postoperative period, (2) removal of plate sutures within 7 days of the tracheostomy procedure, (3) placement of a polyurethane foam dressing after suture removal, and (4) neutral positioning of the head.

Access to Subspecialty Care And Survival Among Patients With Liver Disease.

Objectives: Access to subspecialty care may be difficult for patients with liver disease, but it is unknown whether access influences outcomes among this population. Our objectives were to determine rates and predictors of access to ambulatory gastrointestinal (GI) subspecialty care for patients with liver disease and to determine whether access to subspecialty GI care is associated with better survival.

Methods: We studied 28,861 patients within the Veterans Administration VISN 11 Liver Disease cohort who had an ICD-9-CM diagnosis code for liver disease from 1 January 2000 through 30 May 2011.

The impact of exposure technique on perioperative complications in patients undergoing elective open abdominal aortic aneurysm repair.

Objective: The objective of this study was to evaluate the impact of exposure technique on perioperative complications in patients undergoing elective open abdominal aortic aneurysm (AAA) repair.

Methods: Using the Society for Vascular Surgery Vascular Quality Initiative database, the study identified patients subjected to open AAA repair from January 2003 to July 2014 and divided them into two aortic exposure groups, retroperitoneal (RP) and transperitoneal (TP). Multivariable analysis was performed to compare the incidence of cardiac events (myocardial infarction, dysrhythmia, heart failure), prolonged intubation, renal dysfunction, and mortality, adjusting for between-group differences identified on univariate analysis.

Diverse Inhaler Devices: A Big Challenge for Health-Care Professionals.

Background: The current variety of medication inhaler devices can be confusing to patients due to the many different delivery systems. Many health-care professionals who prescribe these devices may not be educated properly about the administration techniques for different inhalers. The objectives of this study were to evaluate various health-care providers' knowledge of specific inhaler devices and to assess their ability to retain this knowledge for a minimum period of 3 months.

Adenosquamous carcinoma of the head and neck: Molecular analysis using CRTC-MAML FISH and survival comparison with paired conventional squamous cell carcinoma.

Objectives/hypothesis: Adenosquamous carcinoma (ASC) is a rare variant of head-and-neck squamous cell carcinoma (HNSCC) generally thought to be uniformly aggressive with poor prognosis. However, it remains unknown how overall survival compare with conventional HNSCC. Here we report for the first time that ASC does not necessarily indicate a worse prognosis than conventional HNSCC.

Spleen size in cirrhosis of different etiologies.

Objectives: The purpose of this study was to evaluate the impact of cirrhosis etiology on spleen size as measured by sonography and computed tomography (CT).

Methods: The spleen images of 139 patients with cirrhosis secondary to alcohol abuse, hepatitis C, or nonalcoholic steatohepatitis were reviewed retrospectively. The maximum diagonal spleen length on a single sonogram and maximum spleen diameter on axial, coronal, or sagittal CT, whichever was largest, was compared among the etiologic groups.

Normative inner ear volumetric measurements.

In the current study, we attempted to determine normative inner ear volumetric measurements generated from three-dimensional computed tomography (CT) images. In addition, we investigated a correlation between the axial length and the volume of the labyrinth and discussed clinical outcomes of this correlation. Amira 5.

Impact of NADiA ProsVue PSA slope on secondary treatment decisions after radical prostatectomy.

Background: Selecting appropriate candidates for postprostatectomy radiotherapy is challenging, because adverse pathological features cannot accurately predict clinical recurrence. Biomarkers that identify residual disease activity may assist clinicians when counseling patients on the risks, benefits and costs of secondary treatment. NADiA ProsVue PSA slope results ≤2.

PDGFR-α inhibition preserves blood-brain barrier after intracerebral hemorrhage.

Objective: Perihematomal edema results from disruption of the blood-brain barrier (BBB) by key mediators, such as thrombin, following intracerebral hemorrhage (ICH). Platelet-derived growth factor receptor alpha (PDGFR-α), a tyrosine kinase receptor, was found in previous studies to play a role in orchestrating BBB impairment. In the present study, we investigated the role of PDGFR-α following ICH-induced brain injury in mice, specifically investigating its effect on BBB disruption.

Application of medical gases in the field of neurobiology.

Medical gases are pharmaceutical molecules which offer solutions to a wide array of medical needs. This can range from use in burn and stroke victims to hypoxia therapy in children. More specifically however, gases such as oxygen, helium, xenon, and hydrogen have recently come under increased exploration for their potential theraputic use with various brain disease states including hypoxia-ischemia, cerebral hemorrhages, and traumatic brain injuries.

Prostaglandin E2 EP1 receptor inhibition fails to provide neuroprotection in surgically induced brain-injured mice.

Recent trials have shown that the prostaglandin E2 EP1 receptor is responsible for NMDA excitotoxicity in the brain after injury. Consequently, in this study, we investigated the use of SC-51089, a selective prostaglandin E2 EP1 receptor antagonist, as a pre-treatment modality to decrease cell death, reduce brain edema, and improve neurobehavioral function after surgically induced brain injury (SBI) in mice. Eleven-week-old C57 black mice (n=82) were randomly assigned to four groups: sham (n=31), SBI (n=27), SBI treated with SC51089 at 10 μg/kg (n=7), and SBI treated with SC51089 at 100 μg/kg (n=17).

Granulocyte colony-stimulating factor treatment provides neuroprotection in surgically induced brain injured mice.

Surgically induced brain injury (SBI) is a common concern after a neurosurgical procedure. Current treatments aimed at reducing the postoperative sequela are limited. Granulocyte-colony stimulating factor (G-CSF), a hematopoietic growth factor involved in the inflammatory process, has been shown in various animal models to be neuroprotective.

Capsaicin pre-treatment provides neurovascular protection against neonatal hypoxic-ischemic brain injury in rats.

Capsaicin, a transient receptor potential vanilloid 1 (TRPV1) agonist, has recently been shown to provide neuroprotection against brain injury in experimental adult models of cerebral ischemia. Accordingly, in this study, we investigated the way in which capsaicin-mediated TRPV1 modulation could attenuate damage in an experimental hypoxic-ischemic (HI) neonatal brain injury model. The Rice-Vannucci method was used in 10-day-old rat pups by performing unilateral carotid artery ligation followed by 2 h of hypoxia (8% O2 at 37°C).
