This consensus-based guideline was developed by all relevant German pediatric medical societies. Ultrasound is the standard imaging modality for pre- and postnatal kidney cysts and should also exclude extrarenal manifestations in the abdomen and internal genital organs. MRI has selected indications. Suspicion of a cystic kidney disease should prompt consultation of a pediatric nephrologist. Prenatal management must be tailored to very different degrees of disease severity. After renal oligohydramnios, we recommend delivery in a perinatal center...

Gastroenterology offers a wide field for future "choosing wisely" recommendations (CWR). They should refer not only to an under- or overuse of diagnostic tools like laboratory or imaging tests but also to an evidence-based application of drug therapies und endoscopic interventions. Drugs like antibiotics or proton pump inhibitors are both often prescribed in the absence of clearly defined underlying diseases and not given when an indication is clear. Similar is true for the ordering of abdominal imaging methods...

OBJECTIVE: Pregnancies conceived via intracytoplasmic sperm injection (ICSI) are associated with a higher risk of fetal cardiac remodeling. The aim of this study was to evaluate whether the type of embryo transfer may affect the magnitude of fetal cardiac remodeling in pregnancies conceived via ICSI. METHODS: Prospective cross-sectional study including 212 pregnancies conceived by ICSI (111 with frozen and 101 with fresh embryos) and 120 spontaneously conceived gestations...

The microcirculation plays a crucial role in the distribution of perfusion to organs. Studies have shown that microcirculatory dysfunction is an independent predictor of morbidity and mortality. Hence, assessment of liver perfusion offers valuable information on the (patho)physiological state of the liver. The current review explores techniques in perfusion imaging that can be used intraoperatively. Available modalities include dynamic contrast-enhanced ultrasound, handheld vital microscopes, indocyanine green fluorescence angiography, and laser contrast speckle imaging...

COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and spreading worldwide has become a serious challenge for the entire health care system as regards infection prevention, rapid diagnosis, and treatment. Lung ultrasound (LUS) is a dynamically developing diagnostic method used in intensive care, cardiology and nephrology, it can also be helpful in diagnosing and monitoring pneumonia. Interstitial pneumonia appears to be the most common clinical manifestation of coronavirus infection...

IMPORTANCE: Infected vallecular cysts should first be treated conservatively and if airway is compromised surgical treatment is considered. OBJECTIVE: The aim of this study was to determine the feasibility and safety of transcervical aspiration of an infected vallecular cyst. DESIGN: A retrospective review of a novel technique that has been used for drainage of vallecular cyst abscesses for 5 years (2012 to 2017). SETTING: Galilee Medical Center affiliated to Azrieli Faculty of Medicine...

Cadmium (Cd) has toxic effect in human body and exists as the inorganic (Cd2+ ) and organic (R-Cd) forms in human biological matrix. Due to cadmium toxicity in various forms, the speciation of cadmium in human blood samples is very important. In this study, the Fe3 O4 -supported naphthalene-1-thiol- functionalized graphene oxide (Fe3 O4 @NpSH-GO, NMNT-GO) as a novel nanomagnetic composite was used for cadmium speciation in blood samples by ultrasound-assisted dispersive magnetic micro solid phase extraction (USA-DM-μ-SPE)...

The new method of the assessment of total sound pressure levels and their A-weighting-filtered counterparts from the sound pressure levels in a selected high-frequency band, reported in previous papers from this series, was tested for four modern techniques of welding: RapidArc, CMT, AC Pulse, and Cold Arc. The measurement results for 113 welding runs were divided into two groups. These in the first group served as data for calculations of the correlation equations for the sound pressure levels, while the others were applied as control ones...

BACKGROUND: Lymphocytopenia is associated with mortality in acute heart failure (AHF), and portal congestion has been suggested to play a role in leukocyte distribution. The associations between lymphocytopenia and ultrasound surrogates for portal congestion have never been studied. We aimed to: characterize the determinants of lymphocytopenia; explore the associations between lymphocytopenia and portal congestion; and explore the relationships between lymphocytopenia and outcomes in AHF...

During the COVID-19 pandemic, we are likely to see a significant increase in the requests for rapid assessment of cardiac function, due to the frequent pre-existence of cardiac pathologies in patients admitted to hospital, and to the emergence of specific cardiac manifestations of this infection, such as myocarditis, sepsis related cardiomyopathy, stress induced cardiomyopathy and acute coronary syndromes. Hand-held, point-of-care ultrasound (HH-POCUS) is particularly suited for the provision of rapid, focused, integrated assessments of the heart and lungs...

Microbubbles with diagnostic ultrasound have had a long history of use in the medical field. In recent years, the therapeutic application of the combination of microbubbles and ultrasound, called sonoporation, has received increased attention as microbubble oscillation or collapse close to various barriers in the body was recognized to potentially open those barriers, increasing drug transport across them. In this review, we aimed to describe the development of lipid-stabilized microbubbles equipped with functions, such as long circulation and drug loading, and the therapeutic application of sonoporation for tumor-targeted therapy, brain-targeted therapy, and immunotherapy...

OBJECTIVES: To analyze the effect of graduated compression stockings on the venous reflux in the lower limbs of pregnant women. METHOD: A controlled randomized clinical trial was performed with sixty women: intervention group (n = 30), who used compression stockings, and control group (n = 30). Using duplex-ultrasound, the reflux time and peak reflux velocity in the great saphenous vein and small saphenous vein were analyzed. RESULTS: Great saphenous vein reflux times in the intervention group were 0...

Thyroid cancer is the most common endocrine cancer and its incidence has continuously increased worldwide. In this paper, we focus on the challenging problem of nodule detection from ultrasound scans. In current clinical practice, this task is performed manually, which is tedious, subjective and highly depends on the clinical experience of radiologists. We propose a novel deep neural network architecture with carefully designed loss function regularization, and network hyperparameters to perform nodule detection without complex post-processing refinement steps...

Objectives: There are conflicting data on the risk of thyroid cancer in thyroid nodules 3 cm or larger, and few such studies on this issue have been conducted in Asia. This study aimed to examine the risk of thyroid cancer in patients with thyroid nodules 3 cm or larger. Methods: This was a seven-year retrospective study conducted in a tertiary referral hospital in Taiwan. All patients with a thyroid nodule measuring ≥ 3 cm who underwent thyroid operation with or without fine-needle aspiration biopsy (FNAB) were included...

AIMS OF THE STUDY: Trauma of the levator ani muscle in the form of partial or complete avulsions is common after vaginal births, especially after vaginal-operative births. As there is little information available regarding associations between the technique of vaginal-operative births and levator ani muscle trauma, we aimed to evaluate the association between the process of vacuum extraction and the occurrence of levator ani muscle trauma. METHODS: As part of a prospective cohort study at the University Hospital of Zurich between March 2017 and April 2019, we sub-analysed vacuum extractions in nulliparous women with singletons in vertex presentation ≥36+0 gestational weeks...
