Orbital cellulitis is a severe and sight-threatening infection of orbital tissues posterior to the orbital septum. The most common causes of orbital cellulitis are rhinosinusitis, orbital trauma, and surgery. Infective endocarditis (IE) is a systemic infection that begins on cardiac valves and spreads by means of the bloodstream to peripheral organs. Septic emboli can spread to any organ including the eyes and can cause focal or diffuse ophthalmic infection. Ocular complications of IE classically include Roth's spots, subconjunctival hemorrhages, chorioretinitis, and endophthalmitis...

BACKGROUND: Posttraumatic stress disorder (PTSD) is characterized by dysregulated arousal and altered cardiac autonomic response as evidenced by decreased high-frequency heart rate variability (HF-HRV), an indirect measure of parasympathetic modulation of the heart. Indeed, subtle threatening cues can cause autonomic dysregulation, even without explicit awareness of the triggering stimulus. Accordingly, examining the neural underpinnings associated with HF-HRV during both sub- and supraliminal exposure to trauma-related cues is critical to an enhanced understanding of autonomic nervous system dysfunction in PTSD...

BACKGROUND: Medical students have limited confidence in performing procedural skills. A pilot study was conducted to evaluate the effect of a multifaceted Procedural Skills Lab (PSL) on the confidence of medical students to perform procedural skills. METHODS: Twelve 2nd year medical students were randomly selected to participate in a pilot PSL. The PSL students met with an instructor for 2 h once a week for 4 weeks. Students participated in a flipped classroom and spaced education program before laboratory sessions that included a cadaver laboratory...

Marisa Cevasco, Prem S Shekar
Tricuspid valve stenosis (TS) is rare, affecting less than 1% of patients in developed nations and approximately 3% of patients worldwide. Detection requires careful evaluation, as it is almost always associated with left-sided valve lesions that may obscure its significance. Primary TS is most frequently caused by rheumatic valvulitis. Other causes include carcinoid, radiation therapy, infective endocarditis, trauma from endomyocardial biopsy or pacemaker placement, or congenital abnormalities. Surgical management of TS is not commonly addressed in standard cardiac texts but is an important topic for the practicing surgeon...

Only 75% of severe tricuspid regurgitation is classified as functional, or related primarily to pulmonary hypertension, right ventricular dysfunction, or a combination of both. Non-functional tricuspid regurgitation occurs when there is damage to the tricuspid leaflets, chordae, papillary muscles, or annulus, independent of right ventricular dysfunction or pulmonary hypertension. The entities that cause non-functional tricuspid regurgitation include rheumatic and myxomatous disease, acquired and genetic connective tissue disorders, endocarditis, sarcoid, pacing, RV biopsy, blunt trauma, radiation, carcinoid, ergot alkaloids, dopamine agonists, fenfluramine, cardiac tumors, atrial fibrillation, and congenital malformations...

BACKGROUND: End-tidal carbon dioxide (EtCO2) is a valuable marker of the return of adequate circulation following cardiac arrest due to medical causes. Previously, the prognostic value of capnography in trauma has been studied among limited populations in prehospital and emergency department settings. We aimed to investigate the relationship between early intraoperative EtCO2 and nonsurvival of patients undergoing emergency surgery at a level 1 academic trauma center as a case series...

Immobilization and bed rest after fracture and orthopedic surgery are routinely advised protocol. Period of bed rest usually depends on the type of injury and orthopedic procedure, ranging from few days to weeks. The trauma, surgery, and immobilization with other contributing factors can lead to deep vein thrombosis and pulmonary embolism (PE) in these patients. Although there is high incidence of PE in such patients, it is difficult to diagnose, primarily because of the variety of nonspecific signs and symptoms...

BACKGROUND: Platelets have been involved in both immune surveillance and host defense against severe infection. To date, whether platelet phenotype or other hemostasis components could be associated with predisposition to sepsis in critical illness remains unknown. The aim of this work was to identify platelet markers that could predict sepsis occurrence in critically ill injured patients. METHODS: This single-center, prospective, observational, 7-month study was based on a cohort of 99 non-infected adult patients admitted to ICUs for elective cardiac surgery, trauma, acute brain injury, and post-operative prolonged ventilation and followed up during ICU stay...

BACKGROUND: The effective treatment of airway compromise in trauma and non-trauma patients is important. Hypoxia and hypotension are predictors of negative patient outcomes and increased mortality, and may be important quality indicators of care provided by emergency medical services. Excluding cardiac arrests, critical trauma and non-trauma patients remain the two major groups to which helicopter emergency medical services (HEMS) are dispatched. Several studies describe the impact of pre-hospital hypoxia or hypotension on trauma patients, but few studies compare this in trauma and non-trauma patients...

Historically, hemoglobin-based oxygen carriers (HBOCs) were being developed as "blood substitutes," despite their transient circulatory half-life (~ 24 h) vs. transfused red blood cells (RBCs). More recently, HBOC commercial development focused on "oxygen therapeutic" indications to provide a temporary oxygenation bridge until medical or surgical interventions (including RBC transfusion, if required) can be initiated. This included the early trauma trials with HemAssist (®) (BAXTER), Hemopure (®) (BIOPURE) and PolyHeme (®) (NORTHFIELD) for resuscitating hypotensive shock...

BACKGROUND: There is great variation in practice regarding the assessment of trauma patients who present with syncope. The purpose of this study was to determine the yield of screening studies (electrocardiogram, echocardiogram, and carotid duplex) and define characteristics to identify groups that may benefit from these investigations. METHODS: We conducted a retrospective cohort study of all trauma patients from 2003 to 2015 who received a carotid duplex as part of a syncope evaluation at our urban Level 1 Trauma Center...

We present two cases of sudden unexpected death (SUD) in elderly individuals in whom autopsy unexpectedly showed Lewy pathology, a hallmark of Parkinson's disease. Both individuals were 68-year-old men who were found dead in their homes without lethal trauma or poisoning. Inquests into their deaths suggested that nonmotor cardiovascular signs of Parkinson's disease might have appeared just before their deaths, although few typical motor signs were present. Autopsy showed Lewy pathology in the heart and peripheral autonomic nervous system in addition to lesser involvement of the brainstem that was consistent with Braak stage 3...

Point-of-care ultrasound (POCUS) is an important modality with many advantages. At the Shaare Zedek Medical Centre, we developed a case-based course to teach POCUS to internal medicine residents and attendings. The topics include: "Introduction to Point-of-Care Ultrasound", "Focused Assessment with Sonography of Trauma", "Basic Cardiac, Pulmonary and Vascular Ultrasound", "Rapid Ultrasound in Shock" and "Ultrasound Guided Central Lines". The use of POCUS should aid in rapid diagnosis, decrease complications associated with bed-side procedures, and ultimately improve patient care...

Efforts to increase the dismal deceased renal transplantation (DRT): live renal transplantation (LRT) ratio in our country have gathered momentum recently, with governmental and non-governmental projects focussing on building public awareness and capacity-building, and appropriate legislation. Worldwide, efforts at increasing the number of organs from the deceased pool have focussed on the use of 'expanded criteria donors', including deceased cardiac donors (DCD). 'Reuse' transplant, where an organ is transplanted after removal from the first recipient, is a rare strategy, used more commonly in liver than in kidney transplantation...

BACKGROUND: Chest compression is a standard recommendation during cardiopulmonary resuscitation (CPR). However, chest compression cannot be effectively applied under certain situations, such as chest wall deformity, rib fracture, or hemopneumothorax. An alternative method, abdominal compression, was reported to achieve better resuscitation outcomes in these patients. MATERIALS AND METHODS: A prospective study was performed in adult patients with cardiac arrest and anticipated ineffective chest compression (thoracic trauma, chest deformity, rib fracture, and hemopneumothorax)...

Shortening the travel time of patient transfer has clinical implications for many conditions such as cardiac arrest, trauma, stroke and STEMI. As resources are often limited precise calculations are needed. In this paper we consider the location problem for both ground and aerial emergency medical services. Given the uncertainty of when patients are in need of prompt medical attention we consider these demand points to be uncertain. We consider various ways in which ground and helicopter ambulances can work together to make the whole process go faster...
