Aortic dissection is a relatively uncommon and potentially misdiagnosed disease. Early and accurate diagnosis and appropriate treatment are imperative for patient survival. In this case, we present a 55-year-old male who presented to the Emergency Department with severe abdominal pain and acute neurological deficits who was triaged for stroke protocol. After unexpected findings on physical examination, other diagnostic hypotheses were evaluated, culminating in the diagnosis of aortic dissection. The purpose of this article is to exemplify a patient who presents with noteworthy neurologic clinical features who ultimately was diagnosed with Type B aortic dissection, to help benefit the rapid diagnosis and subsequent treatment for future patients with similar presentations.

Background Since the declaration of the novel Corona Virus Disease (COVID-19) as a global pandemic by the World Health Organization, frontline healthcare workers (HCWs) and staff in the Emergency Departments (ED) started experiencing feelings of anxiety and fear from the projected exponential spread and the potential burden on the healthcare system and infrastructure. In Lebanon, major local factors contributing to this fear were the rapid escalation of COVID-19 cases across the country, the lack of preparedness, and the shortage of personal protective equipment, in addition to the evolving economic crisis and financial restrictions. This study aims to investigate the immediate psychological impact of the COVID-19 outbreak on ED staff working in a hospital environment in relation to their household income. Methods Self-reported cross-sectional survey was delivered to the frontline staff working at the Department of Emergency Medicine of AUBMC in Beirut, Lebanon. General demographic characteristics, scores of Generalized Anxiety Disorder 7 (GAD-7), scores of Patient Health Questionnaire 9 (PHQ-9), and scores of Burnout Measure-Short (BMS) version were collected. Results 74 HCWs (49.6%) participated in the study. The mean age for participants was (31.78 ± 9.49). More than half of the participants were nurses and more than 70% reported a monthly salary of less than 2000 USD. The household income was negatively associated with the participant's scores on the GAD-7 and PHQ-9, but not the BMS. Previous mental health diagnosis was positively associated with the PHQ-9 and BMS scores, while seeking mental health care was negatively associated with the PHQ-9 and BMS scores. Conclusion At our tertiary care center in a low-income, low resource country amidst the COVID-19 pandemic, the HCWs reported marked psychological disturbances on different scales. In particular, the financial burden was associated with increased anxiety and clinical depression, but was not associated with burnout.

Objectives This study sought to determine whether the increased use of telehealth was associated with a difference in outcomes for outpatients with heart failure. Background The COVID-19 pandemic led to dramatic changes in the delivery of outpatient care. It is unclear whether increased use of telehealth affected outcomes for outpatients with heart failure. Methods In March 2020, a large Midwestern health care system, encompassing 16 cardiology clinics, 16 emergency departments, and 12 hospitals, initiated a telehealth-based model for outpatient care in the setting of the COVID-19 pandemic. A propensity-matched analysis was performed to compare outcomes between outpatients seen in-person in 2018 and 2019 and via telemedicine in 2020. Results Among 8,263 unique patients with heart failure with 15,421 clinic visits seen from March 15 to June 15, telehealth was employed in 88.5% of 2020 visits but in none in 2018 or 2019. Despite the pandemic, more outpatients were seen in 2020 (n = 5,224) versus 2018 and 2019 (n = 5,099 per year). Using propensity matching, 4,541 telehealth visits in 2020 were compared with 4,541 in-person visits in 2018 and 2019, and groups were well matched. Mortality was similar for telehealth and in-person visits at both 30 days (0.8% vs 0.7%) and 90 days (2.9% vs 2.4%). Likewise, there was no excess in hospital encounters or need for intensive care with telehealth visits. Conclusions A telehealth model for outpatients with heart failure allowed for distanced encounters without increases in subsequent acute care or mortality. As the pressures of the COVID-19 pandemic abate, these data suggest that telehealth outpatient visits in patients with heart failure can be safely incorporated into clinical practice., Central Illustration

Immune checkpoint inhibitors (ICIs) are increasingly used in the treatment of cancer. Immune checkpoint inhibitors may cause a wide-range of autoimmune toxicities referred to as immune-related adverse events (irAEs). There is a paucity of data regarding the presentations and outcomes of patients receiving ICIs who seek care in an emergency department (ED). We performed a retrospective review of patients receiving an ICI who presented to a tertiary care ED between May 1, 2017, and April 30, 2018. Data including ED chief complaint, diagnosis, treatment, and disposition were collected along with baseline characteristics and diagnosis at the time of outpatient oncology follow-up. We report descriptive statistics summarizing the characteristics of the cohort. There were 98 ED visits identified among 67 unique patients. Immune-related adverse events were diagnosed in 16 (16.3%) cases. The most common chief complaints within the irAE group were gastrointestinal symptoms 10 (62.5%). Among the 16 confirmed irAE cases, the most common irAE diagnosed was colitis 9 (56.3%). Two (12.5%) patients with irAEs received corticosteroids during their stay in the ED, and 10 (62.5%) patients with irAEs required hospital admission. Emergency medicine providers documented consideration of an irAE in the differential diagnosis in 14.3% of all ED visits and in 43.8% of visits in which an irAE was ultimately diagnosed. Emergency providers should be familiar with ICIs given their expanding use and potential adverse effects to improve early recognition and patient outcomes in ED settings.

Background Nursing home (NH) residents are prioritized for COVID-19 vaccination. We report monthly mortality, hospitalizations, and emergency department (ED) visit incidence rates (IRs) during 2010–2020 to provide context for COVID-19 vaccine safety assessments. Methods We observed outcomes among all NH residents in Ontario using administrative databases. IRs were calculated by month, sex, and age group. Comparisons between months were assessed using one-sample t-tests; comparisons by age and sex were assessed using chi-squared tests. Results From 2010 to 2019, there were 83,453 (SD: 652.4) NH residents per month, with an average of 2.3 (SD: 0.28) deaths, 3.1 (SD: 0.16) hospitalizations, and 3.6 (SD: 0.17) ED visits per 100 residents per month. From March to December 2020, mortality IRs were increased, but hospitalization and ED visit IRs were reduced (p Conclusion We identified consistent monthly mortality, hospitalization, and ED visit IRs during 2010–2019. Marked differences in these rates were observed during 2020, coinciding with the COVID-19 pandemic.

Introduction Symptoms of COVID-19 vary in severity and presentation. When admitting patients to the hospital, it is desirable to isolate patients with COVID-19 from those without the disease. However, reliably identifying patients with COVID-19 in the emergency department before hospital admission is often limited by the speed and availability of testing. Previous studies determined a low lymphocyte count is commonly found in patients with COVID-19. We sought to explore the sensitivity of absolute lymphocyte count in patients presenting to the emergency department requiring subsequent hospitalization who were found to have COVID-19. Methods A retrospective chart review was performed on 312 patients with laboratory-confirmed COVID-19 who were admitted to the hospital from the emergency department. The absolute lymphocyte count for these patients was used to calculate sensitivities at various cut-off values. The relationships between absolute lymphocyte count and variables, including age, sex, need for intubation, and mortality, were also explored. Results Cut-off values for absolute lymphocyte count ranged from 1.1 K/uL to 2.0 K/uL, with sensitivities of 72% and 94%, respectively. Additionally, lower mean absolute lymphocyte counts were identified in males, patients who required intubation, and patients who died. Conclusion Knowing the sensitivity of absolute lymphocyte count in patients with COVID-19 may help identify patients who are unlikely to have the disease. Additionally, absolute lymphocyte count can be used as a marker of disease severity in patients with COVID-19.

BACKGROUND: In times of health resource reallocation, capacities must remain able to meet a continued demand for essential, nonambulatory neurosurgical acute care. This study sought to characterize the demand for and provision of neurosurgical acute care during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This single-center cross-sectional observational analysis compared nonambulatory neurosurgical consult encounters during the peri-surge period (March 9 to May 31, 2020) with those during an analogous period in 2019. Outcomes included consult volume, distribution of problem types, disease severity, and rate of acute operative intervention. RESULTS: A total of 1494 neurosurgical consults were analyzed. Amidst the pandemic surge, 583 consults were seen, which was 6.4 standard deviations below the mean among analogous 2016-2019 periods (mean 873; standard deviation 45, P = 0.001). Between 2019 and 2020, the proportion of degenerative spine consults decreased in favor of spinal trauma (25.6% vs. 34% and 51.9% vs. 41.4%, P = 0.088). Among aneurysmal subarachnoid hemorrhage cases, poor-grade (Hunt and Hess grades 4-5) presentations were more common (30% vs. 14.8%, P = 0.086). A greater proportion of pandemic era consults resulted in acute operative management, with an unchanged absolute frequency of acutely operative consults (123/583 [21.1%] vs. 120/911 [13.2%], P < 0.001). CONCLUSIONS: Neurosurgical consult volume during the pandemic surge hit a 5-year institutional low. Amidst vast reallocation of health care resources, demand for high-acuity nonambulatory neurosurgical care continued and proportionally increased for greater-acuity pathologies. In our continued current pandemic as well as any future situations of mass health resource reallocation, neurosurgical acute care capacities must be preserved.

OBJECTIVES: This study describes the utilization of a pediatric emergency department (ED) during the early months of the COVID-19 pandemic in the initial U.S. epicenter, including the impact on visit acuity and incidences of common diagnoses. STUDY DESIGN: We performed an observational retrospective review of patients younger than 18 years old seen in a New York City pediatric ED from March 7th to May 6th 2020, and during the same time period in 2018 and 2019. Demographics, visit details, diagnoses, and dispositions were compared. Validated algorithms were utilized to create practical diagnosis groupings and to determine the probability of a visit requiring emergent evaluation. RESULTS: ED visits during the pandemic decreased by 56% to an average daily census of 67 patients, from an anticipated 152. Admission rates rose from 13.3% to 17.4% (p

Most heart failure hospitalizations are due to volume overload; however, it is not easily evaluated by physical examination. Avoidance of diuresis in patients with fluid overload to avoid acute kidney injury increases morbidity in heart failure. We hypothesize that fractional excretion of urate can be used to guide diuresis. (Level of Difficulty: Advanced.), Central Illustration

The mobilization of subspecialty departments in reaction to the unique demands of the onset of the coronavirus disease 2019 (COVID-19) pandemic in New York City was swift and left little time for reflection and commemoration. The early days of the pandemic brought unprecedented stressors on the medical system that necessitated a restructuring of hospitals, reallocation of health care workers, and a shift in care and education paradigms to meet patient care demands and public health needs. As the number of cases, intensive care unit patients, and deaths skyrocketed in New York City, many struggled with a somewhat paradoxical difficulty in perceiving the human value of what these numbers mean. Easily lost in the statistics are the stories and experiences of the physicians and trainees who were counted on to halt their own clinical practices and adapt their skillsets to tackle the pandemic. In this article, we present 10 brief narratives from the student members of the Neurosurgery Publication Group at Weill Cornell Medical College and members of the Weill Cornell Medicine Neurological Surgery Residency Program and Department of Neurological Surgery faculty. Reflecting on these individual experiences gives us an opportunity to simultaneously contribute to a history of New York City's reaction to COVID-19 and commemorate the individuals who were impacted by or succumbed to this disease.

Context The global COVID-19 pandemic has had a major impact on the utilization of healthcare services; however, the impact on population-level emergency department (ED) utilization patterns for the treatment of acute injuries has not been fully characterized. Objective This study examined the frequency of North Carolina (NC) EDs visits for selected injury mechanisms during the first eleven months of the COVID-19 pandemic. Methods Data were obtained from the NC Disease Event Tracking and Epidemiologic Collection Tool (NC DETECT), NC's legislatively mandated statewide syndromic surveillance system for the years 2019 and 2020. Frequencies of January – November 2020 NC ED visits were compared to frequencies of 2019 visits for selected injury mechanisms, classified according to International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) injury diagnosis and mechanism codes. Results In 2020, the total number of injury-related visits declined by 19.5% (N = 651,158) as compared to 2019 (N = 809,095). Visits related to motor vehicle traffic crashes declined by a greater percentage (29%) and falls (19%) declined by a comparable percentage to total injury-related visits. Visits related to assault (15%) and self-harm (10%) declined by smaller percentages. Medication/drug overdose visits increased (10%), the only injury mechanism studied to increase during this period. Conclusion Both ED avoidance and decreased exposures may have contributed to these declines, creating implications for injury morbidity and mortality. Injury outcomes exacerbated by the pandemic should be addressed by timely public health responses.

BACKGROUND: The COVID-19 pandemic has significantly affected patient care across specialties. Ramifications for neurosurgery include substantial disruptions to surgical training and changes in nonurgent patient presentations to the emergency department. This study quantifies the effects of the COVID-19 pandemic on the number of emergency department patients who were referred to the neurosurgery department for further consultation and treatment and identifies and describes trends in the characteristics of these visits. METHODS: A retrospective review was performed of neurosurgical consultations at a single high-volume institution for 28 call-day periods before and after the official announcement of the pandemic. Primary outcomes included consultations per call-day, patient presentation category, and patient admission. RESULTS: The neurosurgical service was consulted regarding 629 patients (367 male patients) during the study period, with 471 (75%) and 158 (25%) patients presenting before and after the announcement of the COVID-19 pandemic, respectively. The mean number of neurosurgical consultations per call-day was significantly lower in the COVID-19 period (5.6 consultations) compared with the pre-COVID-19 period (16.8 consultations) (P < 0.001). After adjusting for patient demographics, the rate of presentation for general nonurgent concerns, such as back pain, headaches, and other general weaknesses, significantly decreased (odds ratio [95% confidence interval], 0.60 [0.47-0.77], P < 0.001). CONCLUSIONS: Neurosurgical consultations significantly decreased after the onset of the COVID-19 pandemic, with a substantially lower overall number of consultations necessitating operative interventions. Furthermore, the relative number of patients with nonemergent neurological conditions significantly decreased during the pandemic.

Clinical signs were consistent with acute Kawasaki disease. (Level of Difficulty: Intermediate.), Graphical abstract

Graphical abstract, The worldwide health crisis caused by the SARS-Cov-2 virus has resulted in>3 million deaths so far. Improving early screening, diagnosis and prognosis of the disease are critical steps in assisting healthcare professionals to save lives during this pandemic. Since WHO declared the COVID-19 outbreak as a pandemic, several studies have been conducted using Artificial Intelligence techniques to optimize these steps on clinical settings in terms of quality, accuracy and most importantly time. The objective of this study is to conduct a systematic literature review on published and preprint reports of Artificial Intelligence models developed and validated for screening, diagnosis and prognosis of the coronavirus disease 2019. We included 101 studies, published from January 1st, 2020 to December 30th, 2020, that developed AI prediction models which can be applied in the clinical setting. We identified in total 14 models for screening, 38 diagnostic models for detecting COVID-19 and 50 prognostic models for predicting ICU need, ventilator need, mortality risk, severity assessment or hospital length stay. Moreover, 43 studies were based on medical imaging and 58 studies on the use of clinical parameters, laboratory results or demographic features. Several heterogeneous predictors derived from multimodal data were identified. Analysis of these multimodal data, captured from various sources, in terms of prominence for each category of the included studies, was performed. Finally, Risk of Bias (RoB) analysis was also conducted to examine the applicability of the included studies in the clinical setting and assist healthcare providers, guideline developers, and policymakers.

Objectives To identify barriers to inpatient alteplase administration and implement an interdisciplinary program to reduce time to systemic thrombolysis. Patients and Methods Compared with patients presenting to the emergency department with an acute ischemic stroke (AIS), inpatients are delayed in receiving alteplase for systemic thrombolysis. Institutional AIS metrics were extracted from the electronic medical records of patients presenting as an inpatient stroke alert. All patients who received alteplase for AIS were included in the analysis. A gap analysis was used to assess institutional deficiencies. An interdisciplinary intervention was initiated to address these deficiencies. Efficacy was measured with pre- and postintervention surveys and institutional AIS metric analysis. Statistical significance was determined using the Student t test. We identified 5 patients (mean age, 73 years; 100% (5/5) male; 80% (4/5) white) who met inclusion criteria for the preintervention period (January 1, 2017, to December 31, 2017) and 10 patients (mean age, 71 years; 50% male; 80% white) for the postintervention period (October 31, 2018, to July 1, 2020). Results We found barriers to rapid delivery of thrombolytic treatment to include alteplase availability and comfort with bedside reconstitution. Interdisciplinary intervention strategies consisted of stocking alteplase on additional floors as well as structured education and hands-on alteplase reconstitution simulations for resident physicians. The mean time from stroke alert to thrombolysis was shorter postintervention than preintervention (57.4 minutes vs 77.8 minutes; P=.03). Conclusion A coordinated interdisciplinary approach is effective in reducing time to systemic thrombolysis in patients experiencing AIS in the inpatient setting. A similar program could be implemented at other institutions to improve AIS treatment.

Highlights • The spleen is normally located in the left hypochondriac region just underneath the 9th to 11th intercostal spaces. • Splenoptosis, wandering spleen or floating spleen, is a rare entity in which the spleen migrates from its normal position. • The diagnosis is confirmed by imaging modalities. • The only definitive treatment is surgical intervention., Background Splenoptosis is an uncommon disorder defined as the dislodgment of the spleen from its anatomical location in the left hypochondrium to another location in the intraabdominal cavity. This migration is the result of laxity or absence of the ligaments that fix the spleen to surrounding structures. Splenoptosis is either diagnosed after it causes symptoms, or incidentally using different imaging modalities. Surgery is the definite treatment either by splenopexy or splenectomy. Case presentation In the case presented here, we discuss a 17 years old female patient who presented to our institution for acute onset of abdominal pain, mainly suprapubic, occurring for 4 days. Ultrasound showed a suspicious right pelvic mass, which was found to be a wandering spleen with pedicle torsion. The patient was treated surgically by splenectomy. Conclusion We report this rare case to encourage physicians to keep this etiology in mind as part of the differential diagnosis of unspecific abdominal pain.

Ventriculoseptal rupture (VSR) is a rare complication of takotsubo syndrome that often requires immediate treatment.

Objective To test the efficacy of an innovative COVID-19 preoperative triage protocol as a way to gradually reopen and ramp-up elective surgeries, we studied our experience and results with 103 non-elective neurosurgical surgeries performed at our institution from March 26th to April 22nd. Patients and Methods We reviewed clinical, radiographic, and laboratory data for all patients that underwent surgery within the neurosurgery department from March 26th to April 22nd 2020. We collected demographic information, comorbidities, pre-operative COVID-19 test result, whether COVID-19 respiratory or other symptoms were developed during hospitalization, hospital length of stay, discharge disposition, and result of post-operative COVID-19 test. Results Using a combination of both preoperative outpatient COVID-19 drive-through and inpatient testing to obtain surgical clearance with selected telemedicine evaluations, 103 non-elective neurosurgical procedures were performed on 102 patients. No patients tested positive for SARS-Cov-2 testing obtained 48h prior to surgery. None of the patients developed any COVID-19 symptoms during their hospitalization or were re-admitted to our ED postoperatively for COVID-19 symptoms. Conclusions We describe a multi-faceted preoperative triage protocol for safely performing non-elective neurosurgical cases during the COVID-19 pandemic, which could help other neurosurgical departments and hospitals minimize coronavirus exposure for patients and healthcare workers. We believe this triage strategy could be implemented at other centers to gradually restart a process towards elective surgeries in a safe way.

Objective To determine whether rapid administration of a crystalloid bolus of 30 mL/kg within 3 hours of presentation harms or benefits hypotensive patients with sepsis with a history of congestive heart failure (CHF). Patients and Methods A retrospective cohort study using Medicare claims data enhanced by medical record data from members of the High Value Healthcare Collaborative from July 1, 2013, to June 30, 2015, examining patients with a history of CHF who did (fluid bundle compliant [FBC]) or did not (NFBC) receive a volume bolus of 30 mL/kg within 3 hours of presentation to the emergency department. A proportional Cox hazard model was used to evaluate the association of FBC with 1-year survival. Results Of the 211 patients examined, 190 were FBC and 21 were NFBC. The FBC patients had higher average hierarchical condition category scores but were otherwise similar to NFBC patients. The NFBC patients had higher adjusted in-hospital and postdischarge mortality rates. The risk-adjusted 1-year mortality rate was higher for NFBC patients (hazard ratio, 2.18; 95% CI, 1.2 to 4.0; P=.01) than for FBC patients. Conclusion In a retrospective claim data-based study of elderly patients with a history of CHF presenting with severe sepsis or septic shock, there is an association of improved mortality with adherence to the initial fluid resuscitation guidelines as part of the 3-hour sepsis bundle.

We present the long-term follow-up of a 31-year-old woman who underwent cardioneuroablation (for atrioventricular (AV) block. Slow pathway ablation was performed in September 2017 with normal follow-up until April 2018, when the patient started noticing symptoms of palpitations at rest, and the electrocardiogram showed a Mobitz I AV block. A cardiac stress test and 24-h Holter monitoring demonstrated first- and second-degree block and normal AV conduction during times of higher heart rate.

This case demonstrates the importance of considering septic pulmonary embolism (SPE) on the differential for chest pain in the pediatric population, especially in patients with a history of skin and soft tissue infection. The adolescent patient in this report, with a history of axillary hidradenitis suppurativa complicated by methicillin-resistant Staphylococcus aureus (MRSA) superinfection and recent completion of a 3-month course of doxycycline, presented with isolated focal chest pain in the absence of other infectious or respiratory signs or symptoms. Initial pulmonary imaging revealed multiple bilateral wedge-shaped nodules. Three specialty teams were consulted in the patient's evaluation, resulting in biopsy of a suspicious lesion that confirmed the diagnosis of MRSA SPE. Following a course of targeted antibiotic therapy, the patient's chest pain resolved and imaging findings improved. Insights gleaned from the workup of this patient are useful in formulating a framework for recognition of SPE in children presenting with chest pain, and also highlight the importance of considering insidious SPE presentation in the setting of antibiotic pretreatment.

Objective To assess the impact on patient experience scores of giving an ice pop (Popsicle, Good Humor-Breyers, Oakland, CA) to patients in a pediatric emergency department (ED). Patients and Methods A prospective two-center trial was conducted at a tertiary academic pediatric ED and a community ED from January 1, 2018, through March 31, 2018. The intervention arm gave an ice pop to all eligible patients 0 to 14 years of age on even-numbered days versus conventional practice on odd-numbered days. Press Ganey top box scores were then compared. Results Of 4574 pediatric (0 to 14 years of age) patient visits, patient experience surveys were delivered to 1346 families (29.4%) and 152 were returned (11.3%). Eighty-four surveys were returned for even-numbered day visits and 68 for odd-numbered day visits. There was a significant increase in patient experience scores associated with ice pop administration days for questions that asked about doctor’s concern for comfort 70.2% versus 57.4% (P=.05), doctor’s courtesy 76.2% versus 61.8% (P=.04), and doctor taking time to listen 72.6% versus 57.4% (P=.03). Conclusion A low-cost intervention resulted in significantly increased patient experience scores in select domains. Popsicle administration was a simple intervention which was easily instituted in both academic and community ED settings. Further study should explore the durability of the effect.

s: Linkou Chang Gung Memorial Hospital, Taiwan has been on the forefront of efforts to manage and mitigate the Coronavirus Disease 2019 (COVID-19) pandemic since 20th January 2020. Despite having one of the largest and busiest emergency departments (EDs) in the world, we have managed to maintain a “zero-infection” rate among our ED healthcare workers through various systematic approaches. The measures implemented include establishing a clear flowchart with route planning, strict infection control policies and regulation of medical equipment, and team-based segregation in the workplace. These strategies, borne of our experience during the severe acute respiratory syndrome (SARS) outbreak, can complement a network of well-trained personnel to enable EDs around the world in successfully mounting an effective defense against new airborne illness while minimizing healthcare personnel casualties.

Cosmetic tattooing has gained popularity over the past several decades. Microblading is a method of semipermanent eyebrow tattooing that has become mainstream in recent years. With this technique, individuals are provided with eyebrow pigment that lasts longer and is more convenient than the traditional eyebrow pencil. Other forms of semipermanent makeup include lip blush, eyebrow tattoos, eyeliner tattoos, freckle tattoos, and scar camouflage. Infection is a rare but major complication of cosmetic tattooing that is rarely documented in the literature. Here, we report a case of preseptal cellulitis secondary to microblading in a middle-aged woman with sickle cell disease (SCD).

Objective Our objective is to describe how polydipsia and intake of nonsteroidal anti-inflammatory drugs (NSAIDs) after fasting while breastfeeding may result in acute symptomatic hyponatremia. Case Report We present the case of a 24-year-old woman at 4 weeks postpartum who engaged in a 20-hour fast from both eating and drinking, during which she continued to breastfeed her newborn child. After ending her fast, she noted decreased milk supply. Attributing her decreased milk supply to dehydration, she then consumed 4 L of water with little salt and also took NSAIDs for a headache, which continued to worsen. Upon presentation to the emergency department, she was found to have a sodium level of 124 mEq/L (normal, 135-145 mEq/L) and a urine specific gravity of 1.015 (normal, 1.005 – 1.030). Thyroid function and cortisol level test results were normal. She was diagnosed with acute symptomatic hypovolemic hyponatremia. After 1 L of normal saline her sodium rapidly corrected to normal and her symptoms resolved. At 2 months of follow-up she was asymptomatic and had no further episodes of hyponatremia. Discussion Due to the patient's gender and small body size, 4 L of water was sufficient to lower her serum sodium rapidly from normal to 124 mEq/L. She was unable to excrete this water due to a combination of hypovolemia-mediated arginine vasopressin and NSAID use. Conclusion Clinicians should be cognizant that reproductive-age women are uniquely susceptible to hyponatremia and dangerous sequelae therein. They should counsel fasting individuals, particularly lactating women, to consume solute as well as fluid after fasting.

Controlling the spread of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), will rely on vaccination at increasing rates and in an equitable manner. The main reasons for under-vaccination are varied among different segments of the population and include vaccine hesitancy and lack of access. While vaccine hesitancy is complicated and requires long-term solutions, access can be enhanced through evidence-based delivery strategies that augment conventional approaches. Hospital-based COVID-19 vaccination programs hold particular promise in reaching populations with decreased vaccine access and those at higher risk for adverse outcomes from SARS-CoV-2 infection. Hospitals have the necessary equipment and storage capabilities to maintain cold chain requirements-a common challenge in the primary care setting-and can serve as a central distribution point for delivering vaccines to patients in diverse hospital locations, including inpatient units, emergency departments, urgent care centers, perioperative areas, and subspecialty clinics. They also have the capacity for mass-vaccination programs and other targeted outreach efforts. Hospital-based programs that have been successful in implementing influenza and other routine vaccinations can leverage existing infrastructure, such as electronic health record-related tools. With the possibility of COVID-19 becoming endemic, much like seasonal influenza, these programs will require flexibility as well as planning for long-term sustainability. This commentary highlights existing vaccine delivery to children in hospital-based settings, including key advantages and important challenges, and outlines how these systems could be expanded to include the COVID-19 vaccine delivery.

The COVID-19 pandemic can exacerbate underlying substance use disorder and has impacted this vulnerable population in a variety of ways. There are limited data regarding how this pandemic has impacted emergency department (ED) patient presentations.We extracted data on ED visits from the electronic health record (EHR) of a large healthcare system in the Washington, DC/Baltimore, MD metropolitan area. The dataset includes data from 7 hospitals on ED visits between 11/1/2019-6/30/2020. The health system utilizes a validated screening program for substance use, Screening, Brief Intervention, and Referral to Treatment (SBIRT), for ED patients who are clinically stable and willing to complete screening. We evaluated trends in patients with a positive SBIRT screen and those presenting with a clinical diagnosis of acute alcohol or substance intoxication/overdose before (11/1/19-2/29/2020-pre) and during the first wave of the COVID pandemic (3/1/2020-6/30/2020-post). Data were described using descriptive statistics. Bivariate analyses were conducted using chi-square test and two-sample t-tests. Interrupted time series analysis was used to evaluate the changes in the weekly trends with the start of the pandemic.There were 107,930 screens performed in the EDs during the study period (61,961 pre, 45,969 post). The population was primarily African American (64.7%) and female (57.1%). Positive SBIRT screens increased from 12.5% to 15.8% during COVID (p 0.001). Alcohol intoxication presentations increased as a proportion of positive screens from 12.6% to 14.4% (p = 0.001). A higher percentage of screened patients reported problem drinking (AUDIT score ≥ 7) during the pandemic (2.4% pre vs 3.2% post, p 0.001). Substance intoxication/overdoses among all screened increased from 2.1% to 3.1% (p 0.001) and as a percentage of positive screens during the pandemic (16.8% to 20%, p 0.001). The proportion of opioid vs. non-opioid overdoses remained unchanged before (67%) and during the pandemic (64%, p = 0.33).There was an increase in the proportion of positive SBIRT screens and visits for acute overdoses and intoxication during the first wave of the COVID-19 pandemic. Additional research should focus on mitigation strategies to address substance use during this vulnerable time.

Introduction and importance Meckel's Diverticulum (MD) is the most occurring congenital anomaly of the gastrointestinal tract. It characterizes a patent remnant of the omphalomesenteric duct. Despite remaining asymptomatic most of the time, the rarity of its occurrence is reflected by the scarcity of data involving it in the literature. Gastrointestinal bleeding, bowel obstruction, and inflammation are the most prevalent complications of MD. Perforation of MD is very rare. Case presentation We present the case of a previously healthy 32-year-old female, who presented to the emergency department with a 2-day-history of generalized abdominal pain. Radiological analysis suggested a perforated viscus and an inflamed Appendix. Clinical discussion Our patient was diagnosed preoperatively with perforated hollow viscus and an exploratory laparotomy was indicated. Intraoperatively, a perforated MD was found and treated by surgical excision of the affected loop of bowel with end-to-end anastomosis and the specimens were sent for histopathological analysis. Histopathology revealed a perforated MD containing gastric mucosa. The patient had successful recovery. Conclusion Early recognition with swift surgical intervention must take place to provide therapeutic outcome for patients and to limit the resulting morbidity. This case highlights the necessity of considering MD as core differential diagnosis in patients with acute abdomen. Due to the scarcity of data on perforated MDs in adult females, it's worthy of studying to highlight its incidence. Due to the rarity of a perforated MD in an adult female, it's worthy to consider such cases to explore preoperative assessment techniques, surgical interventions options, and postoperative complications., Highlights • MD is a rare gastrointestinal anomaly comprising 2% of congenital abnormalities of the GI tract. • Complications of MD range from GI bleeding, diverticulitis, neoplasm, to perforation. • MD mostly remains silent and is rarely complicated in adults, especially in adult females. • Perforation of MD is the rarest of the complications and it would mostly occur in males rather than in females.

Stones are the most common cause of collecting system ruptures. There are few reported cases of a ruptured collecting system without an underlying pathological cause. We report a case of a 15-year-old female patient who presented with left flank pain that was associated with nausea and vomiting. Computed tomography revealed a large, left retroperitoneal fluid collection, which was associated with severe hydronephrosis without an obvious pathological cause. The patient was treated with the insertion of a left double-J stent, and a retrograde pyelography confirmed the cessation of extravasation. At follow up, she was treated surgically with left robotic-assisted pyeloplasty without complications.

Introduction The Abbott ID Now COVID-19 assay is a point-of-care molecular diagnostic tool for the detection of SARS-CoV-2. We prospectively monitored implementation of the assay in a tertiary care hospital emergency department (ED) for the diagnosis of early symptomatic patients. Methods A total of 269 paired nasopharyngeal swabs were tested in parallel with the ID Now and laboratory-based molecular methodologies, 191 of which met selection criteria for testing based on symptoms description and duration. Results 46 and 48 samples were positive for SARS-CoV-2 with the ID Now and reference molecular assays respectively. Percent positive and negative agreement were high (93.8% and 99.6% respectively), as were the sensitivity and specificity (93.8% and 99.5%). ID Now results were available 17.47 hours earlier than qRT-PCR. Conclusion In symptomatic patients seen in ED within 7 to 10 days of symptoms onset, the ID Now COVID-19 assay allows for rapid and accurate detection of infection.

Summary Infection prevention and control team members (IPCTM) are often intimidated by aspects of ventilation as they relate to healthcare, because they consider them technical and outside their area of comfort and expertise. However, engineers, estates departments and planners need IPCTM input to ensure appropriate design and use. The main areas of importance centre on the operating theatre, the provision of air-controlled ventilated isolation rooms, and how to respond to major outbreaks/pandemics. Concentrating on basic principles of infection prevention and control, developing relationships with key departments and individuals, and applying best practice to these and other areas as they arise, are of great value. Some background, information and suggestions are provided for IPCTM with a view to providing simple practical advice in these areas.

Background and objectives: Since the COVID-19 pandemic confinement was established in Spain on March 9, 2020, the number of visits to the paediatric Emergency Department (ED) has decreased dramatically, probably due to the fear of parents becoming infected in the hospital environment. The aim of this work was to analyse the medium-term consequences during the first 9 months after the onset of the COVID-19 pandemic in children with acute appendicitis (AA). Material and Methods: A retrospective study was performed on children operated on for AA in our institution between 2017-2020, who were distributed in two groups according to the date of surgery: COVID-19 group (after March 9, 2020) and control group (before March 9, 2020). Demographic variables, associated symptoms, time from symptoms onset, hospital stay, rate of complicated AA and postoperative complications were analysed. Results: A total of 1274 patients were included (288 COVID group; 986 control group), without demographic differences. Time from symptom onset was significantly longer in COVID-19 group (34.5 vs. 24.2 hours; p=0.021), although no differences in associated symptoms were observed between both groups. COVID-19 group presented a higher rate of complicated AA (20.1% vs. 14%; OR: 1.55; CI95%[1.10-2.18]; p=0.008), a longer hospital stay (3.5 vs. 2.8 days; p=0.042) as well as a higher rate of postoperative complications (21.5% vs. 15.7%; OR: 1.47; CI95%[(1.06-2.04)]; p=0.008). Conclusion: In our experience there was a negative medium-term effects of the COVID-19 pandemic on children with acute appendicitis: delayed ED visits, increased rate of complicated AA, increased hospital stay and increased postoperative complications.

We aimed to describe the epidemiology of trauma activations and variations in injury patterns, injury severity, and hospital length-of-stay for injured children in Los Angeles (LA) County during the coronavirus-disease-19 (COVID-19) pandemic.We conducted a retrospective cross-sectional study of children aged 18-years evaluated in 15 trauma centers from 2019 to 2020 and entered in the LA County trauma registry. We defined 01/01/2019-03/18/2020 as pre-pandemic and 03/19/2020-12/31/2020 as the pandemic period. Our primary outcome was pediatric trauma activations. We analyzed demographic and clinical data, including types and severity of injuries sustained. We conducted unadjusted bivariate analyzes of injury patterns between periods. Segmented linear regression models were used to test rates (per 100,000 LA County children) of trauma activations pre-pandemic versus the pandemic period.We studied 4399 children with trauma activations, 2695 of which occurred pre-pandemic and 1701 in the pandemic period. Motor vehicle collisions, gunshot wounds, and burns increased during the pandemic (all p-values 0.05), while sports injuries decreased (p 0.001). Median injury severity scores (p = 0.323) and Glasgow Coma Scales (p = 0.558) did not differ between periods, however mortality (p = 0.023) decreased during the pandemic. Segmented linear regression estimates demonstrated that rates of trauma activations pre-pandemic were similar to the pandemic period (p = 0.384).Pediatric trauma activations in LA County did not significantly differ during the COVID-19 pandemic, but types and severity of injuries varied between pre-pandemic and pandemic periods. With lockdown restrictions being lifted and novel SARS-CoV-2 variants circulating, our investigation describes this recent epidemiologic phenomenon to aid future preparation for healthcare systems.Level III TYPE OF STUDY: Retrospective cross-sectional study.

After the publication of a 2014 consensus statement regarding mass critical care during public health emergencies, much has been learned about surge responses and the care of overwhelming numbers of patients during the COVID-19 pandemic. Gaps in prior pandemic planning were identified and require modification in the midst of severe ongoing surges throughout the world.A subcommittee from The Task Force for Mass Critical Care (TFMCC) investigated the most recent COVID-19 publications coupled with TFMCC members anecdotal experience in order to formulate operational strategies to optimize contingency level care, and prevent crisis care circumstances associated with increased mortality.TFMCC adopted a modified version of established rapid guideline methodologies from the World Health Organization and the Guidelines International Network-McMaster Guideline Development Checklist. With a consensus development process incorporating expert opinion to define important questions and extract evidence, the TFMCC developed relevant pandemic surge suggestions in a structured manner, incorporating peer-reviewed literature, "gray" evidence from lay media sources, and anecdotal experiential evidence.Ten suggestions were identified regarding staffing, load-balancing, communication, and technology. Staffing models are suggested with resilience strategies to support critical care staff. ICU surge strategies and strain indicators are suggested to enhance ICU prioritization tactics to maintain contingency level care and to avoid crisis triage, with early transfer strategies to further load-balance care. We suggest that intensivists and hospitalists be engaged with the incident command structure to ensure two-way communication, situational awareness, and the use of technology to support critical care delivery and families of patients in ICUs.A subcommittee from the TFMCC offers interim evidence-informed operational strategies to assist hospitals and communities to plan for and respond to surge capacity demands resulting from COVID-19.

Objective: Graves’ disease is an autoimmune thyroid disease that is thought to develop following environmental exposure in patients with genetic predisposition. Our objective is to present the first report of Graves’ disease onset immediately following recovery from mild coronavirus disease 2019 (COVID-19), a close temporal occurrence that should be studied further. Methods: We describe the clinical course and laboratory features, including thyroid function studies, antibody testing, and polymerase chain reaction testing for severe acute respiratory syndrome coronavirus 2. Results: A 21-year-old woman with prediabetes, obesity, asthma, and gastroesophageal reflux disease presented to the emergency department reporting 3 days of tachycardia, palpitations, anxiety, and shortness of breath. Laboratory investigation revealed a thyroid-stimulating hormone level of 0.01 (0.30-5.00) mcIU/mL with a free thyroxine level of 3.8 (0.6-1.6) ng/dL, prompting endocrinology consultation. On physical examination, she had mild diffuse thyromegaly without tenderness and a history, which included hypothyroidism in her mother. Antibody testing results demonstrated thyroid-stimulating immunoglobulin and thyrotropin receptor antibody levels of 2.6 (

Objective To assess how staff attitudes before, during, and after implementation of a real-time location system (RTLS) that uses radio-frequency identification tags on staff and patient identification badges and on equipment affected staff's intention to use and actual use of an RTLS. Participants and Methods A series of 3 online surveys were sent to staff at an emergency department with plans to implement an RTLS between June 1, 2015, and November 29, 2016. Each survey corresponded with a different phase of implementation: preimplementation, midimplementation, and postimplementation. Multiple logistic regression with backward elimination was used to assess the relationship between demographic variables, attitudes about RTLSs, and intention to use or actual use of an RTLS. Results Demographic variables were not associated with intention to use or actual use of the RTLS. Before implementation, poor perceptions about the technology's usefulness and lack of trust in how employers would use tracking data were associated with weaker intentions to use the RTLS. During and after implementation, attitudes about the technology's use, not issues related to autonomy and privacy, were associated with less use of the technology. Conclusion Real-time location systems have the potential to assess patterns of health care delivery that could be modified to reduce costs and improve the quality of care. Successful implementation, however, may hinge on how staff weighs attitudes and concerns about their autonomy and personal privacy with organizational goals. With the large investments required for new technology, serious consideration should be given to address staff attitudes about privacy and technology in order to assure successful implementation.
