Fever is a common presenting complaint to the pediatric emergency department (PED), especially among oncology patients. While bacteremia has been extensively studied in this population, pneumonia has not. Some studies suggest that chest X-ray (CXR) does not have a role in the investigation of neutropenic fever in the absence of respiratory symptoms, yet non-neutropenic pediatric oncology patients were excluded from these studies. We aimed to determine the incidence of CXRs ordered for febrile pediatric oncology patients, irrespective of their absolute neutrophil count (ANC), and to evaluate the rates of radiographic pneumonia as well as predictors of the latter in this group. This study was conducted in the PED at the American University of Beirut Medical Center (AUBMC), an Eastern Mediterranean tertiary-care hospital. We conducted a retrospective cohort study of acutely febrile pediatric cancer patients, younger than 18 years, presenting to a tertiary center from 2014 to 2018. We included one randomly selected febrile visit per patient. Fever was defined as a single oral temperature ≥38 °C within 24 h of presentation. We collected data on patient characteristics and outcomes. Our primary outcome was radiographic pneumonia; our secondary outcome was whether a CXR was done or not. We defined radiographic pneumonia as a consolidation, pleural effusion, infiltrate, pneumonia, "infiltrate vs. atelectasis," or possible pneumonia mentioned by the radiologist. SPSS was used for the statistical analysis. We reviewed a total of 664 medical charts and included data from 342 febrile pediatric patients in our analysis. Of these, 64 (18.7%) had a CXR performed. Overall, 16 (25%) had radiographic pneumonia while 48 (75%) did not. Patients were significantly more likely to have a CXR performed if they presented with upper respiratory tract symptoms, cough (p < 0.001 for both), or abnormal lung auscultation at the bedside (p = 0.004). Patients were also less likely to have a CXR done if they were asymptomatic upon admission to the PED (p < 0.001). However, neither cough nor shortness of breath nor abnormal lung examinations were significant predictors of a positive CXR (p = 0.17, 0.43, and 0.669, respectively). Patients with radiographic pneumonia were found to be significantly younger (4.29 vs. 6 years, p = 0.03), with a longer time since their last chemotherapy (15 vs. 7 days, p = 0.005), and were given intravenous (IV) bolus in the PED (87.5% vs. 56.3%, p = 0.02). Interestingly, patients with higher white blood cell (WBC) counts were more likely to have radiographic pneumonia (4850 vs. 1750, p = 0.01). Having a cough and an abnormal lung examination on presentation increased the odds of having a CXR (adjusted odds ratio [aOR]: 6.6; 95% confidence interval [CI]: 3.4–12.8 and aOR: 4.5; 95% CI: 1.1–18.3, respectively). Returning to the PED for the same complaint within 2 weeks was associated with lower odds of a CXR at the index visit (aOR: 0.3; 95% CI: 0.1–0.6). For every year the child is older, the odds of having radiographic pneumonia decreased by 0.8 (95% CI: 0.6–0.98). However, for every day since the last chemotherapy session, the odds increased by 1.1 (95% CI: 1.01–1.12). In our sample, CXR was not commonly performed in the initial assessment of febrile cancer patients in the PED, unless respiratory symptoms or an abnormal lung examination was noted. However, these were not significant predictors of radiographic pneumonia. Further studies are needed to identify better predictors of pneumonia in this high-risk population. [ABSTRACT FROM AUTHOR]

The aim of this study is to describe the difference between carboxyhemoglobin (CO-Hb) acute poisoning caused by waterpipe vs non-waterpipe exposures as they relate to demographics, clinical presentations and outcome of patients. Retrospective cohort study conducted in the Emergency Department (ED) at the Lebanon. All adult patients presenting with a CO-Hb level ≥ 10 between January 2019 and August 2023 with exposure types stratified as waterpipe or non-waterpipe. 111 ED visits were identified. Among these, 73.9% were attributed to waterpipe exposure, while 26.1% were non-waterpipe sources. These included cigarette smoking (17.2%), burning coal (24.1%), fire incidents (3.6%), gas leaks (6.9%), heating device use (10.3%), and undocumented sources (37.9%). Patients with waterpipe-related carbon monoxide exposure were younger (41 vs 50 years, p = 0.015) women (63.4 vs 41.4%, p = 0.039) with less comorbidities compared to non-waterpipe exposures (22.2 vs 41.4%, p = 0.047). Waterpipe smokers were more likely to present during the summer (42.7 vs 13.8%, p = 0.002) and have shorter ED length of stays (3.9 vs 4.5 h, p = 0.03). A higher percentage of waterpipe smokers presented with syncope (52.4 vs 17.2%, p = 0.001) whereas cough/dyspnea were more common in non-waterpipe exposures (31 vs 9.8%, p = 0.006). The initial CO-Hb level was found to be significantly higher in waterpipe exposure as compared to non-waterpipe (19.7 vs 13.7, p = 0.004). Non-waterpipe exposures were more likely to be admitted to the hospital (24.1 vs 4.9%, p = 0.015). Waterpipe smokers had significantly higher odds of experiencing syncope, with a 5.74-fold increase in risk compared to those exposed to non-waterpipe sources (p = 0.004) irrespective of their CO-Hb level. Furthermore, males had significantly lower odds of syncope as compared to females, following carbon monoxide exposure (aOR 0.31, 95% CI 0.13–0.74). CO-Hb poisoning related to waterpipe smoking has distinctive features. Syncope is a commonly associated presentation that should solicit a focused social history in communities where waterpipe smoking is common. Furthermore, CO-Hb poisoning should remain on the differential in patients presenting with headache, syncope, dizziness, vomiting or shortness of breath, even outside of the non-waterpipe exposure peaks of winter season.

Residency is expected to be a long and difficult road. When living in Lebanon, however, this path can be even more demanding. This reflection is my story, an Emergency Medicine Resident at the American University of Beirut Medical Center living in Lebanon. In this essay, I narrate how I experienced the past two years in Lebanon from protests, to an economic collapse, to a massive urban explosion and a pandemic. This narrative is a reflection on the challenges experienced as both an Emergency Medicine resident and a Lebanese citizen working in these settings. [ABSTRACT FROM AUTHOR]

Background: Despite the advantages of bone marrow transplantation (BMT), patients receiving this intervention visit the emergency department (ED) frequently and for various reasons. Many of those ED visits result in hospitalization, and the length of stay varies.Objectives: The objective of our study was to identify the patients who were only briefly hospitalized and were thus eligible for safe discharge from the ED.Methods: This was a retrospective cohort study conducted on all adult patients who have completed a successful BMT and had an ED visit that resulted in hospitalization.Results: Our study included 115 unique BMT with a total number of 357 ED visits. Around half of those visits resulted in a short hospitalization. We found higher odds of a short hospitalization among those who have undergone autologous BMT (95%CI [1.14-2.65]). Analysis of the discharge diagnoses showed that patients with gastroenteritis were more likely to have a shorter hospitalization in comparison to those diagnosed with others (95%CI [1.10-3.81]). Furthermore, we showed that patients who presented after a month from their procedure were more likely to have a short hospitalization (95%CI [1.04-4.87]). Another significant predictor of a short of hospitalization was the absence of Graft versus Host Disease (GvHD) (95%CI [2.53-12.28]). Additionally, patients with normal and high systolic blood pressure (95%CI [2.22-6.73] and 95%CI [2.81-13.05]; respectively), normal respiratory rate (95%CI [2.79-10.17]) and temperature (95%CI [2.91-7.44]) were more likely to have a shorter hospitalization, compared to those presenting with abnormal vitals. Likewise, we proved higher odds of a short hospitalization in patients with a quick Sepsis Related Organ Failure Assessment score of 1-2 (95%CI [1.29-5.20]). Moreover, we demonstrated higher odds of a short hospitalization in patients with a normal platelet count (95%CI [1.39-3.36]) and creatinine level (95%CI [1.30-6.18]).Conclusion: In our study, we have shown that BMT patients visit the ED frequently and many of those visits result in a short hospitalization. Our study showed that patients presenting with fever/chills are less likely to have a short hospitalization. We also showed a significant association between a short hospitalization and BMT patients without GvHD, with normal RR, normal T °C and a normal platelet count. [ABSTRACT FROM AUTHOR]
