Ultrasound primary care

INTRODUCTION AND IMPORTANCE: Meningiomas are an extra-axial tumour arising from arachnoid cells and are typically benign and slow growing. Primary extradural meningiomas refer to meningiomas that arise outside the subdural compartment and are extremely rare (0.3 % of meningiomas). CASE PRESENTATION: A 42-year-old female presented to her primary health care provider with a 2-year history of a painful mass on her left forehead with a past medical history of a traumatic brain injury and intracranial hematoma from a motor vehicle accident when she was 11 months old...

PURPOSE: In a certain proportion of dichorionic twin pregnancies, the two placentas are fused. The clinical significance of this finding remains unclear. Our objective was to compare outcomes of dichorionic twin pregnancies with fused versus separate placentas as determined on first-trimester ultrasound. METHODS: Retrospective study of patients with dichorionic twins followed at a tertiary center between 2014 and 2022. The co-primary outcomes were fetal growth restriction and preeclampsia...

In recent years, bedside ultrasound examinations have been used in many clinical departments and are called point-of-care ultrasound (POCUS). Regarding POCUS in the cardiac field, a protocol called focus (focused) cardiac ultrasound (FoCUS) has been developed in Europe and the United States, is being used clinically, and an educational syllabus has been created. According to them, FoCUS is defined as a point-of-care cardiac ultrasound examination using standardized limited sections and protocols. FoCUS is primarily intended to be performed by non-cardiologists, and in order to avoid making mistakes in judgment, it is important to be familiar with its limitations and it is necessary to understand pathological conditions that can only be diagnosed using conventional comprehensive echocardiography...

BACKGROUND: Venous access in patients with obesity presents significant challenges. The success of central venous catheterisation largely depends on the cross-sectional area (CSA) of the internal jugular vein (IJV). While techniques like the Trendelenburg position have been traditionally used to increase IJV CSA, recent studies suggest its ineffectiveness in patients with obesity. Conversely, the potential of the effect of passive leg raising (PLR) has not been thoroughly investigated in this group of patients...

INTRODUCTION: This observational study conducted across seven emergency care units compares the efficacy of four D-dimer detection methods, namely HemosIL D-dimer HS (HS), HemosIL D-dimer HS-500 (HS-500), VIDAS D-dimer (VIDAS), and HemosIL AcuStar D-dimer (ACUSTAR). The primary focus is on patients with a clinical suspicion of deep venous thrombosis (DVT) or pulmonary embolism (PE). METHODS: A total of 149 samples were collected from patients with suspected DVT or PE...

BACKGROUND: Acute respiratory distress syndrome (ARDS) is a frequent cause of hypoxemic respiratory failure with a mortality rate of approximately 30%. Identifying ARDS subphenotypes based on "focal" or "non-focal" lung morphology has the potential to better target mechanical ventilation strategies of individual patients. However, classifying morphology through chest radiography or computed tomography is either inaccurate or impractical. Lung ultrasound (LUS) is a non-invasive bedside tool that can accurately distinguish "focal" from "non-focal" lung morphology...

OBJECTIVES: Chest tube thoracostomy site selection is typically chosen through landmark identification of the fifth intercostal space (ICS). Using point-of-care ultrasound (POCUS), studies have shown this site to be potentially unsafe in many adults; however, no study has evaluated this in children. The primary aim of this study was to evaluate the safety of the fifth ICS for pediatric chest tube placement, with the secondary aim to identify patient factors that correlate with an unsafe fifth ICS...

CLINICAL/METHODICAL ISSUE: Neuroendocrine tumors (NET) represent a heterogeneous group of rare tumors that predominantly arise in the gastrointestinal tract. At the time of initial diagnosis, the NET has already spread locoregionally in about half of the patients, and 27% of patients have already developed distant metastases. Since this plays a crucial role in therapy planning, accurate diagnostic imaging is important. STANDARD RADIOLOGICAL METHODS: Due to its high temporal and spatial resolution (multiphasic including arterial phase), computed tomography (CT) plays a decisive role in primary staging and follow-up care, while magnetic resonance imaging (MRI) with its excellent soft tissue contrast offers advantages in the assessment of parenchymal organs in the upper abdomen...

BACKGROUND: The Lung Ultrasound (LUS) is routinely used as a point-of-care imaging tool in Emergency Department (ED) and its role in COVID-19 is being studied. The Lung UltraSound Score (LUSS) is a semi quantitative score of lung damage severity. Alongside instrumental diagnostic, the PaO2/FiO2 (P/F) ratio, obtained from arterial blood gas analysis, is the index used to assess the severity of the acute respiratory distress syndrome (ARDS), according to the Berlin definition. OBJECTIVES: The primary objective of the study was to evaluate a possible correlation between the LUSS score and the P/F Ratio, obtained from the arterial sampling in COVID-19 positive patients...

BACKGROUND: Urinary tract infections (UTIs) are a common cause of acute illness among infants and young children. There are numerous methods for collecting urine in children who are not toilet trained. This review examined practice variation in the urine collection methods for diagnosing UTI in non-toilet-trained children. METHODS: A systematic review was completed by searching MEDLINE (Ovid), Embase (Ovid), CENTRAL (Ovid), PsycInfo (Ovid), CINAHL (EBSCO), and JBI (Ovid) from January 1, 2000 until October 9, 2021 and updated on May 24, 2023...

Color pulsed-wave Doppler ultrasound (CPWD-US) emerges as a pivotal tool in intensive care units (ICUs) for diagnosing acute kidney injury (AKI) swiftly and non-invasively. Its bedside accessibility allows for rapid assessments, making it a primary imaging modality for AKI characterization. Furthermore, CPWD-US serves as a guiding instrument for key diagnostic-interventional procedures such as renal needle biopsy and percutaneous nephrostomy, while also facilitating therapy response monitoring and AKI progression tracking...

OBJECTIVES: This prospective cohort study aimed to investigate changes in intracranial pressure (ICP) and cerebral hemodynamics in infants with congenital heart disease undergoing the Glenn procedure, focusing on the relationship between superior vena cava pressure and estimated ICP. DESIGN: A single-center prospective cohort study. SETTING: The study was conducted in a cardiac center over 4 years (2019-2022). PATIENTS: Twenty-seven infants with congenital heart disease scheduled for the Glenn procedure were included in the study, and detailed patient demographics and primary diagnoses were recorded...

BACKGROUND: Currently, clinical assessment is the main tool for the evaluation of brachial plexus injury, complemented by electrophysiologic studies (EPS), and imaging studies whenever available. Imaging plays an important role as it enables the differentiation of pre-ganglionic and postganglionic injuries, and adds objectivity to presurgical evaluation. OBJECTIVES: The primary objective was to evaluate the utility of magnetic resonance imaging (MRI) and high-resolution ultrasonography (USG) in the localization and characterization of brachial plexus injury in infants...

BACKGROUND: Short-term poor uterine involution manifests as uterine contraction weakness. This is one of the important causes of postpartum hemorrhage, posing a serious threat to the mother's life and safety. The study aims to investigate whether low-intensity focused ultrasound (LIFUS) can effectively shorten lochia duration, alleviate postpartum complications, and accelerate uterine involution compared with the sham treatment. METHODS: A multicenter, concealed, randomized, blinded, and sham-controlled clinical trial was conducted across three medical centers involving 176 subjects, utilizing a parallel group design...

We analyzed the risk factors and outcomes of antenatally diagnosed congenital diaphragmatic hernia (CDH) from a tertiary-care children's hospital following in-utero transfer. A total of 41 antenatally detected cases of CDH were included; 30 were live-born and 11 were still-born. The primary outcome was postnatal survival. The secondary outcome was the probable factor affecting survival. No medical termination of the pregnancy was done. The mean gestational age at diagnosis was 23 weeks. The diagnostic accuracy of antenatal ultrasonography was 40/41 (97...

Non-invasive imaging plays an increasingly important role in emergency medicine, given the trend towards smaller, portable ultrasound devices, the integration of ultrasound imaging across diverse medical disciplines, and the growing evidence supporting its clinical benefits for the patient. Heart failure with preserved ejection fraction (HFpEF) provides a compelling illustration of the impactful role that imaging plays in distinguishing diverse clinical presentations of heart failure with numerous associated comorbidities, including pulmonary, renal, or hepatic diseases...

The aim of this study is to estimate the diagnostic accuracy of abdominal point of care ultrasound (POCUS) performed by family physicians (FPs) in primary care (PC), in comparison with the findings in the medical record (MR) at 12 months of follow-up. This study is conducted entirely in PC healthcare centers in Spain. Abdominal ultrasound scans performed by FPs (selected on the basis of their ultrasound knowledge and experience) are compared with the findings, or not, in the patient's MR after a 12-month follow-up period...

BACKGROUND: Pulmonary Hypertension (PH) is a condition with several cardiopulmonary etiologies that has the potential of progressing to right heart failure without proper intervention. After a history, physical exam, and investigations, cases of suspected PH typically undergo imaging via a transthoracic echocardiogram (TTE). This is a resource-intensive procedure that is less accessible in remote communities. However, point of care ultrasound (POCUS), a portable ultrasound administered at the bedside, has potential to aid in the diagnostic process of PH...

Background and Objectives : Placenta accreta spectrum (PAS) disorders are placental conditions associated with significant maternal morbidity and mortality. While antenatal vaginal bleeding in the setting of PAS is common, the implications of this on overall outcomes remain unknown. Our primary objective was to identify the implications of antenatal vaginal bleeding in the setting of suspected PAS on both maternal and fetal outcomes. Materials and Methods : We performed a case-control study of patients referred to our PAS center of excellence delivered by cesarean hysterectomy from 2012 to 2022...

Nerves in patients with diabetic neuropathy (DN) show increased susceptibility to local anesthetics, potentially requiring a decreased dose. We investigated whether the minimum effective anesthetic concentration (MEAC) of mepivacaine for successful axillary block is lower in patients with DN than in those without. This prospective observational study included patients with DN ( n = 22) and without diabetes ( n = 22) at a tertiary care center. Patients received an ultrasound-guided axillary block with 30 mL of mepivacaine for anesthesia...
