Case Report: Bilateral Pneumothorax Following T2–T5 Medial Branch Nerve Block, Jenna Rapone Md

Rowan-Virtua Research Day

Bilateral pneumothorax is an uncommon but clinically significant complication of thoracic spinal interventions. We report the case of a 20-year-old female with underlying scoliosis who developed acute pleuritic chest pain, dyspnea, and persistent cough immediately following bilateral T2–T5 medial branch nerve block injections performed in an outpatient pain management setting.  Thoracic medial branch blocks are generally considered low-risk procedures; however, the proximity of the pleura to posterior thoracic elements places patients at risk for iatrogenic pleural injury, particularly in individuals with altered spinal anatomy such as scoliosis. This case underscores the importance of maintaining a high index of suspicion for …

Case Report: Vancomycin-Resistant Enterococcus Faecium Urinary Tract Infection With Stercoral Colitis Presenting In An Elderly Patient, Muhammad Zain Raza, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We report a case of a 76-year-old female who presented with altered mental status characterized by confusion, decreased verbal interaction, and reduced responsiveness noted by her spouse. The patient had a history of chronic constipation and was brought from home for further evaluation. Initial evaluation raised concern for infection or intracranial hemorrhage as a possible cause of altered mental status. Imaging of the CT brain without contrast was unremarkable, however; abdomen and pelvis revealed a large rectal stool impaction with rectal wall thickening and surrounding perirectal fat stranding consistent with Stercoral Colitis. Urine culture subsequently identified vancomycin-resistant enterococcus faecium. The …

Acute Appendicitis With Concomitant Testicular Torsion, Thuc Vu, Clara Keum, Swet Patel, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

This case report presents a 13-year-old male who presented to the emergency department with diffuse abdominal pain radiating to the right lower quadrant, accompanied by nausea and decreased appetite. Diagnostic evaluation revealed right-sided testicular torsion concurrent with acute appendicitis. Although acute appendicitis represents the most common surgical emergency in the pediatric population, clinicians must maintain a broad differential diagnosis to identify potential concomitant acute pathologies, including testicular torsion in this scenario.

The Klatskin Tumor: A Tumor At The Liver’S Crossroads, Asma Zahid, Sergey Medlenov, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We present a 68-year-old female with no significant oncologic history who presented to

the emergency department with a  two –week history of progressive jaundice and diarrhea.

Systematic ED evaluation revealed marked hyperbilirubinemia (total bilirubin 22.3 mg/dL), a

cholestatic laboratory pattern, and multimodal imaging demonstrating multifocal hepatic

masses, a porta hepatis soft tissue mass,  and biliary ductal dilatation consistent with hilar cholangiocarcinoma (Klatskin tumor) with metastatic disease.

A CA 19-9 marker was markedly elevated at 379 U/mL. The patient was admitted and she underwent successful biliary decompression via ERCP with stent placement.  Outpatient oncologic therapy was initiated. This case highlights the …

Heterotopic Pregnancy: A Case Report, Oluwatomi Alade, Robin Lahr, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Heterotopic pregnancy occurs when there is simultaneous intrauterine pregnancy as well as extra uterine ectopic pregnancy.  Historically, this was considered very rare with an estimated incidence of 1 in 30,000 pregnancies however, the incidence has been increased with the use of assisted reproductive  technology.  The most common location is the fallopian tube and less common include the cervix or the ovary. It can be difficult to diagnose because the presence of an intrauterine pregnancy on ultrasound may falsely reassure clinicians and delay evaluation for a concurrent ectopic pregnancy.  These patients usually present with nonspecific symptoms including abdominal pain, vaginal bleeding, …

Acute Ischemic Stroke In Hemoglobin Sc Sickle Disease Requiring Emergent Exchange Transfusion And Neurocritical Transfer, Julian Coz, Trent Malcolm, Andrew Iskandar, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Acute ischemic stroke is a well-recognized complication of sickle cell disease (SCD), with historical estimates suggesting that up to 11% of patients experience an overt stroke by early adulthood. Stroke represents a hematologic and neurologic emergency requiring rapid reduction of the circulating hemoglobin S (HbS) fraction to prevent infarct progression. The American Society of Hematology recommends emergent exchange transfusion within two hours of presentation for patients with acute neurologic deficits [1,3].

Management is particularly nuanced in hemoglobin SC (HbSC) disease. Compared with hemoglobin SS disease, patients with HbSC typically have higher baseline hemoglobin concentrations, increasing blood viscosity and the risk …

Case Report: Ascending Cholangitis Presenting As Sepsis With Encephalopathy In An Older Adult With Choledocholithiasis, David Marconi, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Acute cholangitis is a potentially life-threatening biliary infection usually precipitated by ductal obstruction. In adults ≥80 years, classic right upper quadrant pain and jaundice may be absent and delirium may predominate, increasing the risk of diagnostic delay.¹

An 82-year-old woman presented with generalized weakness and altered mental status. She was febrile (101.9 °F [38.8 °C]) and tachycardic (113 beats/min) without hypotension. Laboratory testing demonstrated leukocytosis and marked cholestatic liver injury (total bilirubin 2.8 mg/dL, alkaline phosphatase 660 U/L) with hyperbilirubinemia and acute encephalopathy consistent with sepsis-associated organ dysfunction. Computed tomography and ultrasound suggested biliary obstruction and cholelithiasis; magnetic resonance cholangiopancreatography …

A Survey-Based Analysis Of The Use Of Lifestyle Medicine In Clinical Practices Of South Jersey, Zehra Jaffri

Rowan-Virtua Research Day

Chronic diseases are the leading cause of death and disability in the United States and are largely driven by modifiable lifestyle factors. Lifestyle Medicine (LM) is an evidence-based medical specialty that uses therapeutic lifestyle interventions—including nutrition, physical activity, stress management, sleep, substance use reduction, and healthy relationships—to prevent, treat, and reverse many chronic conditions. Despite strong evidence supporting lifestyle interventions, LM use in routine primary care remains inconsistent due to barriers such as limited visit time, inadequate clinician training, lack of reimbursement, and difficulty sustaining behavioral change. This study evaluates how often lifestyle counseling is discussed in South Jersey primary …

A Rare Intervention: Emergency Ultrasound-Guided Pericardiocentesis Using A Central Line Kit, Alec Mirchandani, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Cardiac tamponade is a life-threatening emergency requiring rapid diagnosis and drainage.

Point-of-care ultrasound (POCUS) expedites recognition and guides pericardiocentesis. We report a case of acute large pericardial effusion with hemodynamic collapse in a previously healthy 46-year-old female, managed emergently with ultrasound-guided pericardiocentesis using a central line introducer and subsequent pigtail catheter exchange; the clinical course was complicated by presumed septic pulmonary emboli and death.

Molten Sugar Burn To The Dorsal Foot: A Case Highlighting Unique Thermal And Adhesive Injury Mechanisms, James Espinosa, Alan A. Lucerna

Rowan-Virtua Research Day

This brief case report emphasizes injury mechanism and anatomic vulnerability rather than burn management, as treatment of deep partial-thickness burns is well established. The clinical value of this case lies in recognizing molten sugar as a uniquely hazardous thermal agent capable of producing deceptively deep injury, particularly when contact occurs on the dorsal foot.

Brief Review: Quantifying The Risks Of Snow Shoveling: Cardiac, Musculoskeletal, And Environmental Hazards, James Espinosa, Swet A. Patel, James Lee, Alan Lucerna

Rowan-Virtua Research Day

Snow shoveling is a common winter activity in cold-weather regions, yet it uniquely combines intense physical exertion, cold exposure, and environmental hazards. Emergency Departments routinely observe seasonal increases in snow-shoveling–related musculoskeletal injuries, falls, and acute cardiovascular events. Despite this, the cardiovascular risk of snow shoveling is not well emphasized in medical education or patient counseling. Snow shoveling is associated with quantifiable and clinically significant risks, including musculoskeletal injury, falls, and acute cardiovascular events, which are reviewed here.

Ice Water Immersion–Associated Syncope: A Case Report With Mechanistic Review And Public Safety Implications, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Sudden ice water immersion can provoke syncope in otherwise healthy individuals, particularly during first-time exposure. We present a case of a 56-year-old man with mild hypertension and hyperlipidemia who experienced abrupt syncope during entry into cold water at a charitable group immersion event. Emergency department evaluation, including electrocardiography and cardiac biomarkers, was normal. Observation and cardiology consultation supported a diagnosis of provoked, immersion-related syncope. This case highlights the physiologic mechanisms of cold shock and autonomic conflict, the potential drowning risk associated with loss of consciousness during water entry, and the opportunity for improved discharge counseling and public safety messaging.

Refeeding Syndrome In A Person Experiencing Homelessness: A Case Report, James Espinosa, Jose Gerald Aragon, Md Fateha, Alan Lucerna

Rowan-Virtua Research Day

Refeeding syndrome (RFS) is a potentially life-threatening metabolic disturbance that occurs following nutritional reintroduction in severely malnourished individuals. It is characterized by rapid intracellular shifts of electrolytes—most notably hypophosphatemia—driven by insulin-mediated metabolic changes. Although commonly associated with eating disorders and chronic illness, RFS may also occur in socially vulnerable populations.

We report the case of a 64-year-old male experiencing homelessness who presented to the emergency department with weakness, muscle cramps, and confusion after resuming regular meals at a local shelter following prolonged minimal intake. Laboratory evaluation revealed severe hypophosphatemia (0.7 mg/dL), hypokalemia (3.0 mmol/L), and hypomagnesemia (1.2 mg/dL). Electrocardiogram demonstrated …

Shopping Cart–Related Injuries In Children: Brief Clinical Review And Public Health Implications, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Shopping cart–related injuries represent a common yet underrecognized mechanism of pediatric trauma. National estimates suggest approximately 24,000 children annually are treated in U.S. emergency departments for shopping cart–related injuries, with falls accounting for the majority of cases. Younger children, particularly those under 5 years of age, are disproportionately affected, and head and facial injuries predominate.

Objective:

To provide a concise clinical and public health review of shopping cart–related pediatric injuries, with emphasis on epidemiology, injury patterns, and opportunities for prevention within emergency department practice.

Methods

Narrative review of national injury surveillance data, prior epidemiologic studies, and consumer safety guidance addressing …

Impostor Phenomenon In Healthcare: Prevalence, Implications, And Educational Responses, James Espinosa, Robin Lahr, Sergey Medlenov, Swet Patel, Nicholas Tomasello, James Lee, Neel Parikh, Alan Lucerna, Henry Schuitema

Rowan-Virtua Research Day

The impostor phenomenon describes persistent self-doubt and fear of being exposed as a fraud despite objective evidence of competence. The term 'impostor phenomenon' is preferred over the term "imposter syndrome" because it is not a psychiatric diagnosis and avoids pathologizing normal developmental uncertainty. The original authors used the term 'phenomenon' (Clance & Imes, 1978), and contemporary scholarship increasingly adopts this terminology.

First described by Clance and Imes (1978), the construct has since been studied across diverse professional domains, including medicine, nursing, and academic leadership. Subsequent research demonstrates that impostor experiences occur across genders, training levels, and healthcare roles (Bravata et …

Learning From Our Dental Colleagues: A Brief Review Of Counter-Stimulation To Reduce Procedural Pain In Emergency Medicine Mechanisms, Existing Evidence, And A Pragmatic Research Agenda, James Espinosa, Neal Appelstein, Alan Lucerna

Rowan-Virtua Research Day

Counter-stimulation techniques such as tapping, pressure, vibration, and tissue shaking are commonly observed in dental practice during administration of local anesthetic nerve blocks. Although not systematically described in the Emergency Medicine literature, individual clinicians may employ tactile counter-stimulation techniques during needle-based procedures. The practice remains under-theorized and under-studied within the Emergency Medicine literature. This brief review synthesizes mechanistic neurobiology—including segmental gate control theory (Melzack & Wall, 1965), descending inhibitory modulation, and attentional salience models—with evidence from dental and needle-procedure research. We propose a practical taxonomy of counter-stimulation techniques applicable to Emergency Medicine and identify gaps in the current literature. Finally, …

From Confirmation To Guidance: Making The Case For Intraprocedural Pocus As The Next Developmental Step In Ultrasound-Supported Shoulder Reduction A Conceptual Practice Proposal And Research Agenda, James Espinosa

Rowan-Virtua Research Day

Point-of-care ultrasound (POCUS) is well established for the diagnosis of shoulder dislocation and for the confirmation of successful reduction. However, its role during the reduction maneuver itself remains under-described. This conceptual practice proposal argues that intraprocedural POCUS represents the logical next developmental step in ultrasound-supported shoulder reduction. By introducing real-time visualization of humeral head translation during reduction attempts, clinicians may identify ineffective vectors earlier, adjust technique midstream, and potentially reduce repeated attempts or escalation of procedural sedation. This work does not present outcome data but instead proposes a practical framework, workflow model, and research agenda for intraprocedural implementation. Future study …

In The Era Of The Smartphone: The Case For The Continued Role Of Mnemonics As Cognitive Scaffolds That Support Encoding, Working Memory Efficiency, And Rapid Cue-Dependent Retrieval, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background: The ubiquity of smartphones and point-of-care digital references has prompted questions regarding the continued relevance of mnemonic devices in medical education. If information can be instantly retrieved, is memorization—and by extension mnemonic structure—still necessary? Objective: To reframe mnemonics not as relics of pre-digital pedagogy, but as cognitive scaffolds that support encoding, working memory efficiency, and rapid cue-dependent retrieval in time-pressured clinical environments. Discussion: Cognitive science demonstrates that working memory remains inherently limited regardless of technological access. Mnemonics function as structured chunks that reduce cognitive load, support pattern recognition, and facilitate transition from novice encoding to expert automaticity. In emergency …

Rainfall, Air Quality, And Vaso-Occlusive Crisis In Adults With Sickle Cell Disease, James Espinosa

Rowan-Virtua Research Day

.Patients with sickle cell disease (SCD) frequently report that weather changes precipitate vaso-occlusive crises (VOC). While prior investigations have focused primarily on temperature, humidity, and seasonal variation, emerging data suggest that rainfall patterns may represent a more meaningful environmental signal. In a multi-hospital Emergency Department analysis, below-average rainfall days were associated with significantly increased adult VOC presentations (Ahmed et al., 2023). Rainfall may function as an atmospheric clearing mechanism; reduced precipitation may permit accumulation of airborne particulate matter and environmental pollutants, increasing oxidative stress and endothelial activation—mechanisms central to vaso-occlusion. Multiple epidemiologic studies demonstrate associations between particulate exposure and increased …

Air Quality, Atmospheric Pressure, And Migraine Presentations In The Emergency Department, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background: Migraine is a leading cause of Emergency Department (ED) visits and global disability. Weather has long been reported by patients as a trigger, yet the literature remains inconsistent. Prior ED-based data demonstrated an association between higher mean barometric pressure and increased migraine presentations, without a relationship to short-term pressure change. Because high-pressure systems are frequently associated with atmospheric stagnation and pollutant accumulation, air quality may represent a biologically plausible mediator.

Objective: To examine the relationship between air quality and ED migraine presentations within the existing body of literature and to explore whether air quality may help explain previously observed …

The Complex World Of Emergency Department Medication Dosing: Weight Scalars, Dose And Area Under The Curve (Auc) In Medication Dosing--Areas For Future Research, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Weight-based dosing is foundational to emergency medicine practice. With modern ED beds capable of automatic patient weighing, inaccuracies in estimated weight have largely diminished. However, medication misalignment persists, particularly in patients at extremes of body weight and in high-stakes clinical contexts such as rapid sequence intubation (RSI), antimicrobial therapy, and anticoagulation. Emerging pharmacokinetic literature emphasizes total drug exposure—represented by the area under the concentration–time curve (AUC)—as a stronger correlate of efficacy and toxicity than single-point serum levels. This review explores where weight precision most likely matters in the ED, examines weight scalars, and reframes dosing decisions through an exposure-centered paradigm. …

Listening To The System: Reframing Emergency Department Noise: The Case For Noise As A Real-Time Operational Signal In A Complex Adaptive System (Cas), James Espinosa, Alan Lucerna, Henry Schuitema

Rowan-Virtua Research Day

Emergency Department (ED) noise has historically been framed as an occupational and environmental hazard requiring mitigation. And this is still true—but not complete. Early work focused on exposure reduction and spike identification. Subsequent mapping studies demonstrated spatial and temporal differentiation in ED acoustic load. We propose an expanded conceptual model: acoustic variability may function not only as a hazard, but also as a real-time signal of operational turbulence within the ED as a complex adaptive system (CAS). Drawing on human factors, alarm fatigue, resilience engineering, and complexity science, we synthesize existing literature and institutional experience to identify a critical gap—noise …

Reset To Learn For Ite And Boards: The Neurobiology Supporting The Advantage Of Micro-Breaks During Content-Dense Lectures--And Why Continuous (No Micro-Breaks) Test-Bank Studying And Test-Taking ("Plowing Through") Is Suboptimal, James Espinosa, Robin Lahr, Swet Patel, James Lee, Alan Lucerna, Henry Schuitema

Rowan-Virtua Research Day

Background: Working memory is a limited-capacity system vulnerable to saturation during sustained cognitive effort. In medical education, board review lectures, intensive test-bank studying, and prolonged examination sessions require extended executive control engagement. Emerging evidence from cognitive neuroscience suggests that brief, intentional cognitive disengagement ('micro-resets')  of even 90 seconds may restore working memory efficiency and improve encoding, integration, and retrieval. This applies to brief breaks during content-dense lectures (needs support of lecturer), during test bank use for preparation as well as for test-taking. Objective: To propose a neurocognitive framework explaining why structured micro-breaks of even 90 seconds can enhance learning during …

The Neurobiology Of Interruptions In Emergency Medicine: The Case For Informed Interruption Management In Support Of Cognitive Stability In High-Reliability Clinical Environments, James Espinosa, Henry Schuitema, Alan Lucerna

Rowan-Virtua Research Day

Background: Interruptions are ubiquitous in Emergency Departments (EDs) and have been associated with task delay, multitasking, and increased error risk. While operational and human-factors impacts are well described, the underlying neurocognitive mechanisms remain underexplored. Not all interruptions are avoidable.  However,  interruptions in emergency medicine represent neurocognitive destabilization events that can degrade task representation and increase vulnerability to error during task resumption. Recognizing the neural mechanisms underlying interruptions reframes their management as a systems-level patient safety priority. The aim is not elimination of clinically necessary communication, but thoughtful reduction, prioritization, and design that protects cognitive stability.

Objective: To synthesize cognitive neuroscience …

Wildfires And Emergency Department Respiratory Surge: Brief Review, Systems Forecasting Implications And Recommendations For Research, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background: Wildfire smoke produces abrupt increases in PM2.5 and Air Quality Index (AQI) levels. Event-based and multi-season studies demonstrate short-term increases in asthma-related Emergency Department (ED) visits, with additional evidence supporting increased utilization for broader respiratory disease and chronic lower respiratory disease (including COPD) (Reid et al., 2016; Liu et al., 2015; Stowell et al., 2025; CDC, 2023).

Objective: To synthesize current evidence linking wildfire smoke to ED respiratory surge and to propose a systems forecasting model that translates environmental signals into structured operational stabilization within a complex adaptive system (CAS).

Methods (Review & Model Development): Narrative synthesis of event-based …

The Physics And Biology Of High-Risk Falls: Biomechanical Analysis And Physics Assists In Understanding Why The Threshold For High-Risk Was Lowered To 10 Feet, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background: Recent revisions to the National Guideline for the Field Triage of Injured Patients lowered the high-risk fall threshold from >20 feet  to >10 feet for all ages. Guideline changes are multifactorial and typically reflect epidemiologic registry data, injury severity trends, and systems-level performance feedback. However, biomechanical analysis assists in understanding the importance of the change.

Objective: To demonstrate that a 10-foot fall generates sufficient kinetic energy and deceleration forces to exceed structural tolerance thresholds in multiple human tissues, and to show that fundamental physics independently supports the recent trauma protocol change.

Methods: Application of gravitational motion equations (v = …

Stroke Mimics And Stroke Chameleons: Leveraging The False Positive/False Negative Diagnostic Schema In Resident Teaching, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background

Stroke mimics and stroke chameleons contribute significantly to diagnostic uncertainty in Emergency Medicine. Traditional teaching often relies on enumerating examples, yet residents struggle to internalize these distinctions.

Objective

To present a conceptual teaching framework that maps stroke mimics to false positives and stroke chameleons to false negatives, leveraging pre-existing diagnostic schemas.

Methods

Using representative cases—including hypoglycemic hemiparesis and spinal epidural lipomatosis presenting as stroke mimic—we developed an explanation for residents involving framing mimics as false positives and chameleons as false negatives.

Results

Framing mimics as false positives and chameleons as false negatives activates existing learner schemas related to sensitivity …

Conceptualizing The Transition From Stable Operations To Turbulent States : Reframing Emergency Department Operations. Learning From Fluid Dynamics And Complexity Science, James Espinosa, David Ho, Alan Lucerna

Rowan-Virtua Research Day

Background: Emergency departments are frequently described using the language of patient flow, implying  smooth and predictable movement of patients through a system versus known obstructions to flow.  Clinicians, however, often observe abrupt shifts in operational stability.

Objective: To explore whether concepts from fluid dynamics and complexity science offer a useful framework for understanding these transitions.

Methods: Conceptual synthesis drawing on emergency medicine operations research, human factors, systems science, and fluid mechanics.

Results (Conceptual): Emergency departments exhibit behaviors analogous to systems approaching turbulence, including sensitivity to perturbation, amplification of delays, and nonlinear responses.

Conclusion: Viewing ED operations through the lens of …

The Ones That Got Away:Shared Misses, Shared Mastery — A Proposal For Leveraging Spaced Retrieval, Variable Reinforcement, And Collective Learning In Emergency Medicine Residency, James Espinosa D, Robin Lahr, James Lee, Swet M. Patel, Alan Lucerna

Rowan-Virtua Research Day

Background

Residents frequently engage in individual question-bank study for board preparation; however, missed questions are typically processed in isolation. Educational psychology demonstrates that spaced retrieval and variable reinforcement enhance durable learning. Psychological safety further supports collective sense-making in professional education . The addition of a periodic, structured, collective shared-review process model may leverage these principles within residency training.

Objective

To propose a resident-driven educational initiative that transforms individually missed board-style questions into a shared, psychologically safe learning stream that promotes durable knowledge retention and community-based mastery.  The movement of this stream could be a chief resident responsibility, or could be …

Soundscapes (Ambient Sound, Noise, Music And Other Background Sound) In The Emergency Department: An Under-Theorized Environmental Modifier In A Complex Adaptive System, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background:

Music and ambient sound (including noise and other sounds) are frequently present in emergency departments (EDs), yet their role as environmental modifiers remains under-theorized. Existing literature largely examines background music, for example,  in procedural or perioperative contexts, with limited attention to open, high-density, multi-agent acute care systems.

Objective:

To conceptualize auditory input as a dynamic environmental variable within the ED viewed as a Complex Adaptive System (CAS), integrating neurobiological mechanisms with systems-level implications.

Methods/Conceptual Approach: Narrative conceptual synthesis integrating neurobiology of auditory processing, affective neuroscience, cognitive load theory, and complexity science.

Results:

Conceptual Insights: Auditory stimuli engage distributed neural …
