Pediatric Trauma During COVID-19: What Have We Learned?

Background: In December 2019, an outbreak of a novel pneumonia-like illness, COVID-19 (C-19), emerged in Wuhan, China. In March 2020, as the incidence of C-19 rose, the Israeli government, like that of other nations, declared a national state of emergency, and a full, general lockdown was announced.

Purpose: The purpose of this study is to determine the incidence and characteristics of pediatric maxillofacial trauma presentation during the 2020 C-19 lockdown restrictions and compare them to periods outside lockdown between 2019 and 2020 (pre-C-19).

Severe chronic nonlichenoid oral mucositis in pembrolizumab-treated patients: new cases and a review of the literature.

To report of severe chronic oral mucositis (OM) in two pembrolizumab-treated cancer patients. A retrospective chart review was performed. Inclusion/exclusion criteria detected patients that developed OM during pembrolizumab immunotherapy.

Dental screening prior to valve interventions: Should we prepare transcatheter aortic valve replacement candidates for "surgery"?

Background: 40% of cases of infective endocarditis (IE) are likely caused by oral bacteria. IE prevalence after transcatheter aortic valve replacement (TAVR) is comparable to IE following surgical prosthetic valve replacement (SVR). Current guidelines recommend pre-operative dental screening for SVR, without specific recommendations regarding TAVR.

The EFSUMB Guidelines and Recommendations for the Clinical Practice of Elastography in Non-Hepatic Applications: Update 2018.

This manuscript describes the use of ultrasound elastography, with the exception of liver applications, and represents an update of the 2013 EFSUMB (European Federation of Societies for Ultrasound in Medicine and Biology) Guidelines and Recommendations on the clinical use of elastography.

World Workshop on Oral Medicine VII: Targeting the oral microbiome Part 2: Current knowledge on malignant and potentially malignant oral disorders.

Objective: The World Workshop on Oral Medicine VII chose the oral microbiome as a focus area. Part 1 presents the methodological state of the science for oral microbiome studies. Part 2 was guided by the question: What is currently known about the microbiome associated with oral squamous cell carcinoma and potentially malignant disorders of the oral mucosa?

Materials And Methods: A scoping review methodology was followed to identify and analyse relevant studies on the composition and potential functions of the oral microbiota using high-throughput sequencing techniques.

Integrating anatomy, radiology, pathology, and surgery: An alternative approach in resecting multifocal and multicentric breast carcinoma.

The sick lobe hypothesis provides the basis for a lobar approach in radiology, pathology, and surgical treatment of breast cancer. This approach aims to remove the tumor together with the surrounding field of genetic aberrations. Detailed preoperative lobar imaging that properly maps the disease and assesses its extent guides the parenchymal resection.

The lobar approach to breast ultrasound imaging and surgery.

Breast cancer is a lobar disease in the sense that, at the earliest stages, the cancer is structurally confined to a single sick lobe. The subgross morphology of breast carcinoma is often complex, as multiple invasive foci are frequently present and the ductal system often contains an extensive in situ component. Adequate preoperative visualization of all of the malignant structures within the affected breast and preoperative mapping of the lesions in relation to the surrounding normal structures are essential for successful image-guided breast surgery and therefore are key factors in assuring adequate local control of the disease.

WFUMB guidelines and recommendations for clinical use of ultrasound elastography: Part 1: basic principles and terminology.

Conventional diagnostic ultrasound images of the anatomy (as opposed to blood flow) reveal differences in the acoustic properties of soft tissues (mainly echogenicity but also, to some extent, attenuation), whereas ultrasound-based elasticity images are able to reveal the differences in the elastic properties of soft tissues (e.g., elasticity and viscosity).

WFUMB guidelines and recommendations for clinical use of ultrasound elastography: Part 3: liver.

The World Federation for Ultrasound in Medicine and Biology (WFUMB) has produced these guidelines for the use of elastography techniques in liver disease. For each available technique, the reproducibility, results, and limitations are analyzed, and recommendations are given. Finally, recommendations based on the international literature and the findings of the WFUMB expert group are established as answers to common questions.

WFUMB guidelines and recommendations for clinical use of ultrasound elastography: Part 2: breast.

The breast section of these Guidelines and Recommendations for Elastography produced under the auspices of the World Federation of Ultrasound in Medicine and Biology (WFUMB) assesses the clinically used applications of all forms of elastography used in breast imaging. The literature on various breast elastography techniques is reviewed, and recommendations are made on evidence-based results. Practical advice is given on how to perform and interpret breast elastography for optimal results, with emphasis placed on avoiding pitfalls.

A 2-D anatomic breast ductal computer phantom for ultrasonic imaging.

Most breast cancers (85%) originate from the epithelium and develop first in the ductolobular structures. In screening procedures, the mammary epithelium should therefore be investigated first by the performing of an anatomically guided examination. For this purpose (mass screening, surgical guidance), we developed a two-dimensional anatomic phantom corresponding to an axial cross section of the ductolobular structures, which makes it possible to better understand the interactions between the breast composition and ultrasound.

Tissue harmonic imaging: utility in breast sonography.

Objective: To determine the impact of tissue harmonic imaging on visualization of focal breast lesions and to compare gray scale contrast between focal breast lesions and fatty tissue of the breast between tissue harmonic imaging and fundamental frequency sonography.

Methods: A prospective study was performed on 219 female patients (254 lesions) undergoing sonographically guided fine-needle biopsy. The fundamental frequency and tissue harmonic images of all lesions were obtained on a scanner with a wideband 7.

B-mode color sonographic images in obstetrics and gynecology: preliminary report.

The standard B-mode image shows 256 levels of gray, but the human eye can only differentiate 8-16 shades of gray. Color vision theoretically has several advantages in comparison with gray scale, because the human eye can distinguish 128 fully saturated hues and about 350,000 shades. In 1992, B-mode color maps were introduced in our clinical practice, to establish whether this technology was able to detect the smallest contrast differences better than the gray-scale map and therefore to increase diagnostic accuracy.

Ultrasonic signs of pneumothorax: preliminary work.

Ultrasonography is considered to have limited application in respiratory diseases because air reflects sound waves. Twenty-four patients with radiologically confirmed pneumothorax and 100 healthy subjects underwent sonography. In all normal subjects, the hyperechoic pulmonary interface showed respiratory motions termed the "gliding sign" with some comet-tail artifacts.
