    Abstract The presence of pulmonary hypertension (PH) may affect whether cardiac tamponade physiology develops from a pericardial effusion. Specifically, the increased intracardiac pressure and right ventricular hypertrophy associated with PH would seemingly increase the intrapericardial pressure threshold at which the right-sided chambers collapse. In this systematic review, we examined the impact of PH on the incidence, in-hospital and long-term mortality, and echocardiographic findings of patients with cardiac tamponade. Using the PRISMA guideline, a systematic search was conducted in PubMed, Academic Search Premier, Web of Science, Google Scholar, and the Cochrane Database for studies investigating PH and cardiac tamponade. The Newcastle-Ottawa Scale was used to analyze the quality of returned studies. Primary outcomes included the incidence of cardiac tamponade, as well as in-hospital and long-term mortality rates. Secondary outcomes were the presence or absence of echocardiographic findings of cardiac tamponade in patients with PH. Forty-three studies (9 cohort studies and 34 case reports) with 1054 patients were included. The incidence of cardiac tamponade was significantly higher in patients with PH compared to those without PH, 2.0% (95% CI 1.2-3.2%) vs. 0.05% (95% CI 0.05-0.05%), p < 0.0001, OR 40.76 (95% CI 24.8-66.9). The incidence of tamponade in patients with a known pericardial effusion was similar in those with and without PH, 20.3% (95% CI 12.0-32.3%) and 20.9% (95% CI 18.0-24.1%), p = 0.9267, OR 0.97 (95% CI 0.50-1.87). In patients with tamponade, those with PH demonstrated a significantly higher in-hospital mortality than those without PH, 38.8% (95% CI 26.4-52.8%) vs. 14.4% (95% CI 14.2-14.6%), p < 0.0001, OR 3.77 (95% CI 2.12-6.70). Long-term mortality in patients with tamponade was significantly lower in those with PH than in those without PH, 45.5% (95% CI 33.0-58.5%) vs. 59.1% (95% CI 54.7-63.4%), p = 0.0258, OR 0.576 (95% CI 0.33-1.01). However, after stratifying by non-malignant etiologies, the long-term mortality benefit for those with PH disappeared. In the studies that described specific echocardiographic findings of cardiac tamponade, only 10.5% of patients with PH and tamponade showed right atrial and right ventricular collapse. When evaluating patients with pericardial effusions, physicians must recognize the effects of underlying PH on the incidence, in-hospital and long-term mortality rates, and potentially atypical echocardiographic presentation of cardiac tamponade.

    Abstract Background: Cumin (Cuminum cyminum L.) is one of the most important medicinal plants, and its essential oil (EO) varies between 2.5% to 5% depending on differences in climate. The extraction method plays a significant role in the market price of EOs. In this study, the effect of atmospheric cold plasma (ACP) pretreatments (using air and argon (Ar) gases) for different times on the EO yield and on the quality, color, surface morphology, and wettability of cumin seeds were studied.
    Results: The scanning electron microscope analysis results revealed that the formation of fissures and cracks caused by ACP pretreatments was directly related to increasing the efficiency of EO extraction. Comparing the two gas treatments, the highest total color changes ΔE were related to the Ar and the lowest to the air treatment, and the highest amount of browning index was related to the Ar ACP pretreatment. In general, the ACP pretreatments improved the extraction efficiency compared with the control, so that the highest increase was observed in the Ar ACP pretreatment at the rate of 44%. Ar ACP pretreatments were observed to have a higher extraction efficiency than air ACP did. In the Ar ACP-treated samples, cumin aldehyde, as the most important component of EO, was increased compared with the control (47.9-56.4%).
    Conclusion: The data obtained in this study showed that ACP pretreatment of cumin seeds could increase EO extraction efficacy. Thus, ACP could be a promising technique to enhance the cumin seed EO extraction. © 2024 Society of Chemical Industry.

    Abstract The diagnosis and treatment of septic arthritis are complex and require collaboration among multiple medical services, especially in the emergency department (ED). This case report highlights the difficulties in diagnosing shoulder septic arthritis, which is a rare condition in adults and can present with subtle symptoms. The patient was eventually diagnosed with septic arthritis of the left shoulder. However, the diagnosis was delayed due to the impact of the COVID-19 pandemic on obtaining an outpatient MRI and a previous shoulder injury that added confusion. Delays in diagnosis and treatment can lead to a rapid destruction of the affected joint, causing significant morbidity and mortality. This case report also highlights the importance of alternative diagnostic tools, such as point-of-care ultrasound (POCUS), which is quick, inexpensive, and may lead to earlier detection of joint effusions and prompt arthrocentesis.

    Abstract This narrative aims to evaluate the efficacy of point-of-care ultrasound (POCUS) in the early diagnosis and management of postprocedural arterial pseudoaneurysms in the emergency department (ED). We hypothesize that POCUS can be used as the first line of imaging to distinguish vascular from non-vascular causes and diagnose a pseudoaneurysm if present. A comprehensive review of cases involving postprocedural pseudoaneurysms was conducted. We focus on patients who underwent endovascular procedures, including transfemoral and transradial arterial access for cardiac interventions, or received laceration repair after blunt head trauma. We analyzed each case's clinical symptoms, POCUS findings, and subsequent management. POCUS demonstrated high efficacy in early diagnosis by detecting pseudoaneurysm sacs with characteristic bi-directional flows (yin-yang sign) and, in some cases, partial thrombosis. The early identification of potential arterial complications allowed for efficient planning of further imaging and expedited surgical consultation, leading to timely and definitive management. Our study emphasizes the significance of using POCUS as the primary imaging modality for early detection and diagnosis of postprocedural arterial pseudoaneurysms. Incorporating POCUS into the initial assessment of patients presenting with pain and swelling at the site of arterial access or laceration repair can streamline consultation and potentially reduce the need for additional imaging, optimizing patient care in the ED setting.

    Abstract Background: Point-of-care ultrasound (POCUS) is an optimal imaging modality for the risk stratification of patients presenting to the emergency department (ED) with inguinal and femoral hernias, allowing for better evaluation of clinical presentations and guiding appropriate treatment. The lack of ultrasound classification for inguinal and femoral hernias has led to inconsistent use and often underuse of POCUS in this patient population. Several groin hernia classifications are available, but most are complex and often targeted toward surgical management.
    Objectives: The objective of this study is to review the use of POCUS in the diagnosis of inguinal and femoral hernias, providing a synopsis of critical ultrasound findings in determining signs of incarceration, strangulation, and small bowel obstruction, and suggesting a simple and educative sonographic classification for inguinal or femoral hernias.
    Discussion: POCUS can reliably confirm the presence of groin hernias and can uniquely identify specific ultrasound findings predictive of complications, such as aperistaltic nonreducible bowel loops, free fluid in the hernia sac, and lack of color doppler in the entrapped mesentery and bowel walls. POCUS can also aid in determining the presence of small bowel obstruction by detecting dilated loops of bowel >25 mm adjacent and proximal to the hernia site.
    Conclusions: In the ED, POCUS can confirm the presence of a hernia sac and identify and predict surgical emergencies, such as bowel incarceration or strangulation, which are the most important elements in the management of patients presenting with possible inguinal or femoral hernias.

    Abstract Giant cell arteritis (GCA), known as temporal arteritis, is a serious condition requiring immediate treatment to prevent complications. GCA can be difficult to diagnose, especially in emergency department (ED) settings where ophthalmology and rheumatology services may be unavailable. Temporal artery ultrasound (TAUS) is a valuable tool for diagnosing GCA. In the ED, TAUS can be used to quickly rule out GCA and avoid unindicated steroid treatment, which can cause serious morbidity in elderly patients. This article discusses the use of TAUS for evaluating patients with suspected GCA in the ED and its potential to expedite treatment and ensure appropriate, timely follow-up for patients with this potential vision and life-threatening condition.

    Abstract Background and objectives: Children with medical complexity (CMC) have significant chronic health conditions that involve congenital or acquired multisystem disease associated with medical fragility, functional limitations, dependence on technology, and high health care utilization. The objective of this study was to describe the indications, applications, and point-of-care ultrasound (POCUS) findings in this population.
    Methods: A descriptive study of POCUS scans performed for clinical purposes in CMC admitted to a single pediatric postacute care hospital. All children for whom a POCUS was requested by a medical team provider were eligible for inclusion.
    Results: One hundred and four POCUS evaluations were performed for 33 patients. Diagnostic groups for the 33 patients included multiple congenital anomalies (41%), neurologic or neuromuscular (31%), prematurity (25%) and cardiac (3%). Lung, cardiac, and diaphragmatic ultrasound accounted for 57% of POCUS requested. POCUS was abnormal in 82% of diaphragmatic, 73% of lung, and 11% of cardiac ultrasounds. Twenty-three percent of POCUS studies were requested to answer a specific clinical question, 56% for follow-up information, and 21% for baseline evaluation.
    Conclusions: Lung, diaphragmatic, and cardiac ultrasound were the most prevalent POCUS studies requested in a postacute care hospital. POCUS may offer an expanded role in such patients and settings by answering clinical questions and by providing baseline and follow-up information.

    Abstract Introduction: Dental abscesses are a common reason patients present to the emergency department (ED). Facial and dental imaging are sometimes necessary to support the clinical diagnosis. While radiographs and computed tomography scans are frequently used, point-of-care ultrasound (US) offers several advantages, including decreased radiation exposure, reduced costs, and shorter patient length of stay. This report outlines the use of US in evaluating patients with suspected dental abscesses in the ED.
    Discussion: The typical orofacial US techniques include examining the affected area for cobblestoning or fluid collections. To improve the accuracy of diagnoses, novel techniques such as the Oral Hydroscan (OHS) and the Tongue Pointing Techniques (TPT) may be employed in specific cases. The OHS utilizes a water-filled oral cavity to enhance the spatial resolution of ultrasound images, providing improved visualization of near-field structures and preventing air accumulation between the gingiva and the buccal mucosa. The TPT involves asking the patient to extend their tongue towards the affected area, pointing to the painful location, and serving as a visual reference for an extraoral US.
    Conclusion: US presents several advantages as an alternative imaging method for patients with suspected dental abscesses in the ED. Using innovative techniques such as the OHS and the TPT can further increase the visibility of tissue planes and help define the area of interest in these cases.
