Shock in newborn infants has unique etiopathologic origins that require careful assessment to direct specific interventions. Early diagnosis is key to successful management. Unlike adults and pediatric patients, shock in newborn infants is often recognized in the uncompensated phase by the presence of hypotension, which may be too late. The routine methods of evaluation used in the adult and pediatric population are often invasive and less feasible. We aim to discuss the pathophysiology in shock in newborn infants, including the transitional changes at birth and unique features that contribute to the challenges in early identification...

BACKGROUND: Portable bed side ultrasound and supine chest radiograph of 80 traumatic patients excluding very clinically unstable patients who subsequently underwent CT scan chest was done for traumatic effusion showing that ultrasound had a higher sensitivity than CXR, 88.23% and 77.94%, respectively, and a similar specificity of 100% and 100%, respectively. Objective of the study is to compare the diagnostic accuracy of high resolution ultrasound and supine chest x-ray in detection of pleural effusion in road traffic accident patients keeping plain CT chest as gold standard...

Recent technical advances in neurosonography continue broadening the diagnostic utility, sensitivity, and specificity of ultrasound for detecting intracranial abnormalities bed side. The clinical and functional applications of neurosonography have significantly expanded since the 1980s when transcranial Doppler sonography first allowed anatomic and hemodynamic delineation of the intracranial vessels through the thin temporal skull. In the past few years, contrast-enhanced ultrasonography, elastography, 3D/4D reconstruction tools, and high-resolution microvessel imaging techniques have further enhanced the diagnostic significance of neurosonography...

About 92.1 million Americans suffer from at least one type of cardiovascular disease. Worldwide, cardiovascular diseases are the number one cause of death (about 31% of all global deaths). Recent technological advancements in cardiac ultrasound imaging are expected to aid in the clinical diagnosis of many cardiovascular diseases. This article provides an overview of such recent technological advancements, specifically focusing on tissue Doppler imaging, strain imaging, contrast echocardiography, 3D echocardiography, point-of-care echocardiography, 3D volumetric flow assessments, and elastography...

How to manage patients with prostate cancer (PCa) with biochemical recurrence (BCR) following primary curative treatment is a controversial issue. Importantly, this prostate-specific antigen (PSA)-only recurrence is a surrogate neither of PCa-specific survival nor of overall survival. Physicians are therefore challenged with preventing or delaying the onset of clinical progression in those deemed at risk, while avoiding over-treating patients whose disease may never progress beyond PSA-only recurrence. Adjuvant therapy for radical prostatectomy (RP) or local radiotherapy (RT) has a role in certain at-risk patients, although it is not recommended in low-risk PCa owing to the significant side-effects associated with RT and androgen deprivation therapy (ADT)...

Point-of-care ultrasound (POCUS) is an important modality with many advantages. At the Shaare Zedek Medical Centre, we developed a case-based course to teach POCUS to internal medicine residents and attendings. The topics include: "Introduction to Point-of-Care Ultrasound", "Focused Assessment with Sonography of Trauma", "Basic Cardiac, Pulmonary and Vascular Ultrasound", "Rapid Ultrasound in Shock" and "Ultrasound Guided Central Lines". The use of POCUS should aid in rapid diagnosis, decrease complications associated with bed-side procedures, and ultimately improve patient care...

RATIONALE: Marijuana use has been increasing in the United States among college students and young adults. Marijuana use has been associated with bullous lung disease which can lead to pneumothorax. There are other recreational drugs like methylphenidate, cocaine and heroin which have been associated with pneumothorax. PATIENT CONCERNS: We present a case of a 30-year-old man with spontaneous pneumothorax associated with marijuana use. The patient had no medical conditions and presented to the emergency room with chest pain...

In the past decade, there has been significant progress in clinical hematology with the discovery of targeted molecules and thus the achievement of both hematologic and molecular responses. Nevertheless, chemotherapy remains the treatment of choice for many types of hematological malignancies. Aggressive chemotherapy leads to immunosuppression, accompanied by a high rate of infections and an increased rate of treatment-related mortality. Invasive fungal infections as well as more common bacterial and viral infections are frequent in immunocompromised patients as they are difficult to diagnose and treat...

Pulmonary embolism (PE) is a life-threatening condition with varied presentation and, therefore, poses clinical challenge for early diagnosis and proper management without which it carries high mortality. Previous studies on the role of endobronchial ultrasound (EBUS) in diagnosis of PE were carried out after PE was already diagnosed by computed tomography pulmonary angiography. We report a case of massive PE with shock, promptly diagnosed with bed side EBUS - Doppler study, as patient's clinical condition did not allow conventionally proposed diagnostic algorithm...

OBJECTIVE: Following radionuclide therapy, patients usually must remain hospitalised in special "restricted access area" 2-5 days, until radiation in their body drops below a certain level. During this period medical personnel can be faced with some challenges. Based on our previous experience, we used telemedicine approach as solution for it. We have developed comprehensive telemedicine system, which consists of three own developed hardware & software modules which are accessible remotely...

The cerebrovascular time constant (τ) theoretically estimates how fast the cerebral arterial bed is filled by blood volume after a sudden change in arterial blood pressure during one cardiac cycle. The aim of this study was to assess the time constant of the cerebral arterial bed in patients with traumatic brain injury (TBI) with and without intracranial hematomas (IH). We examined 116 patients with severe TBI (mean 35 ± 15 years, 61 men, 55 women). The first group included 58 patients without IH and the second group included 58 patients with epidural (7), subdural (48), and multiple (3) hematomas...

REVIEW
Gebhard Mathis
Imaging of pulmonary embolism (PTE) remains a great challange. Mortatity is even high. Possibilities of lung ultrasound, echocardiography, and compression leg vein sonography are discussed. Hemodynamic instable patients should achieve echocardiography at bed side with an accuracy of 90% and immeadiatly treated. In case of a suspected PTE, compression sonography of the leg veins is recommended. It can be performed within 2 min but, on average, yields a positive result in only one-half of the cases of PTE. During the last years, pulmonary sonography took root as a complementary method to MSCT either when the latter is not available or when it is contraindicated because of contrast agent allergy, renal insufficiency, or pregnancy...

A vein of Galen arteriovenous malformation (VGAM) is a rare intracranial shunt lacking a capillary bed and resulting in subsequent aneurysmal enlargement. VGAM has been previously reported to present as cardiovascular abnormalities, including increased right-sided cardiac load and pressure, cardiac dilatation, pulmonary hypertension and retrograde flow into the aortic arch. We report the first case of VGAM presenting as a gross right-sided neck swelling in a 39-week-old immediately at birth. Transthoracic echocardiography detected dilatation of the superior vena cava and innominate vein, increased right ventricular and pulmonary arterial pressure, and retrograde flow into the aortic arch...

Purpose: Vascular ultrasound (US) allows the analysis of vascular strain by speckle-tracking. This study sought to assess the extent to which vas cular strain varies between different segments of the arterial tree. Furthermore, this study aimed to investigate the reproducibility of vascular strain determination as well as of the components that contribute to the variance of vascular strain measurements in different vascular beds. Materials and Methods: Speckle-tracking was used to determine the vascular strain of the abdominal aorta (AA), the common carotid artery (CCA), the common femoral (CFA) and the popliteal artery (PA) of healthy adults...
