INTRODUCTION: Thyroid cancer is the most common pediatric endocrine cancer; accurate diagnosis and prompt management of pediatric thyroid nodules is critical. The McGill Thyroid Nodule Score (MTNS), based upon clinical, ultrasound (US), and cytology criteria has recently been modified and studied in a pilot pediatric group with good results. We aim to describe the diagnostic accuracy of the pediatric modified MTNS (PMTNS) in a large pediatric cohort. METHODS: We utilized an established retrospective cohort between 1996 and 2015 of 99 patients ≤ 21 years old with 131 thyroid nodules...

BACKGROUND: Living kidney donation for transplantation has become common practice. The decisions to accept a donor with nephrolithiasis are becoming frequent. AIM: The aim of our study was to report our experience in the living donor kidney with asymptomatic lithiasis. METHODS: Over a period of 4 years from 2009 to 2013 we collected 18 cases. From the clinical, metabolic and radiological data, we have determined the etiology of urolithiasis in our patients and established, after a literature review, a decision tree of kidney donation...

Early detection of vascular damage in atherosclerosis and accurate assessment of cardiovascular risk factors are the basis for appropriate treatment strategies in cardiovascular medicine. The current review focuses on non-invasive ultrasound-based methods for imaging of atherosclerosis. Endothelial dysfunction is an accepted early manifestation of atherosclerosis. The most widely used technique to study endothelial function is non-invasive, flow-mediated dilation of the brachial artery under high-resolution ultrasound imaging...

Chronic kidney disease (CKD) is commonly present in patients undergoing percutaneous coronary intervention (PCI). These patients frequently present with more complex coronary artery disease (CAD) and higher risk of peri-procedural and post-procedural adverse events, including bleeding, thrombotic events, and contrast-induced acute kidney injury (CI-AKI). This article contains updated knowledge and management of patients with CKD undergoing PCI. Areas covered: In this article, the pathophysiological mechanisms behind the association of CKD, complex CAD lesions, and complications of PCI are reviewed and the different risk scores available to assess the occurrence of CI-AKI are detailed...

In 2018, the American Cancer Society (ACS) estimates that 164,690 new cases of prostate cancer will be diagnosed and 29,430 will die due to the prostate cancer in the United States (Siegel et al., CA Cancer J Clin 67:7-30, 2018). Many men with prostate cancer are often managed with aggressive therapy including radiotherapy or surgery. No matter how expertly done, these therapies carry significant risk and morbidity to the patient's health related quality of life with impact on sexual, urinary and bowel function (Potosky et al...

Biliary ascariasis is a tropical infectious disease, endemic in regions such as the Far East, Indian subcontinent and parts of the Middle East. The responsible organism is the Ascaris lumbricoides worm. This case study presents a 54-year-old British Caucasian female patient, admitted with a 1-week history of generalized abdominal pain. Ultrasound scan of the abdomen showed a collapsed and abnormal image of the gallbladder. Further imaging for better visualization by magnetic resonance cholangiography showed a 6 cm linear structure in the gallbladder...

Objective: This study was to evaluate the effectiveness of ultrasound-guided percutaneous ozone injections around the cervical dorsal root ganglions of zoster-associated pain (ZAP) patients. Study design: Retrospective comparative study. Settings: The study was conducted at a pain center of a university hospital. Patients and methods: From June 2016 to July 2017, a total number of 30 patients with ZAP were treated with ultrasound-guided percutaneous ozone injection around the cervical dorsal root ganglion (DRG) at the injured nerve level (C2-C8)...

(2) To establish whether the device was likely to have been placed at the fundus at insertion. (3) To document removal success rates in a community sexual health (CSH) setting. STUDY DESIGN: A retrospective review of a series of 76 women seen by the author between April 2016 and October 2017 in a specialist CSH clinic for removal of IUC with non-visible threads...

AIM: To assess the quality of YouTube videos explaining transrectal ultrasound (TRUS)-guided biopsies of the prostate. MATERIALS AND METHODS: A search of YouTube was made for the terms "TRUS", "TRUS biopsy", "transrectal ultrasound", and "prostate biopsy".

BACKGROUND: Speckle tracking echocardiography (STE) is a novel technology that measures regional wall-motion abnormalities that may speed diagnosis and intervention of acute coronary occlusion in Emergency Department (ED) patients with non-ST elevation ACS (NSTE-ACS). STE provides an objective measurement of myocardial strain that is superior to visual assessment of wall motion when performed as part of a point-of-care (POC) echocardiogram. We determined the feasibility and preliminary accuracy of POC STE operated by emergency providers when compared to comprehensive echocardiography or final diagnosis of ACS...

Background : Chest ultrasound (CUS) has been shown to be a sensitive and specific imaging modality for pneumothorax, pneumonia, and pleural effusions. However, the role of chest ultrasound in the diagnosis of thoracic tuberculosis (TB) is uncertain. We performed a systematic search in the medical literature to better define the potential role and value of chest ultrasound in diagnosing thoracic tuberculosis. Aim : To describe existing literature with regard to the diagnostic value of chest ultrasound in thoracic tuberculosis...

Nucleic acids (NAs) have been considered as promising therapeutic agents for various types of diseases. However, their clinical applications still face many limitations due to their charge, high molecular weight, instability in biological environment and low levels of transfection. To overcome these drawbacks, therapeutic NAs should be carried in a stable nanocarrier, which can be viral or non-viral vectors, and released at specific target site. Various controllable gene release strategies are currently being evaluated with interesting results...

Introduced at the end of the '50s, ultrasound has widely developed and spread since then. Not limited to morphological information, sonography more and more includes elements of functional imaging. The new technological developments of ultrasound, and the main fields of application of sonography are reviewed, as well as the management of the so-called ultrasound incidentaloma. The triangular relationship between the patient, the ultrasound machine, and the operator are reviewed, with a special attention to those parameters affecting the final results of an ultrasound examination...

Background: Primary breast rhabdomyosarcoma (RMS) can occur in children. There is a lack of knowledge regarding radiologic findings and added diffusion-weighted magnetic resonance imaging (MRI) features of RMS in the literature. Case Report: A 12-year-old girl was diagnosed with primary alveolar RMS of the breast. Gray scale ultrasound revealed posterior acoustic enhancement behind a well-circumscribed, multilobulated hypoechoic mass. Doppler ultrasound revealed increased peripheral and central vascularity...

We present a case of a patient with a large, symptomatic abdominal tumour, which finally could be classified as a leiomyoma arising from the right seminal duct/seminal vesicle. In computed tomography (CT) scan, it appeared as a 7.5 × 6.5 cm solid, supravesical mass. A cystoscopy as well as bilateral retrograde studies was normal, a transrectal ultrasound-guided biopsy and an ultrasound-guided transabdominal biopsy of the mass were inconclusive. Subsequently, we performed a tumour extirpation through a lower midline laparotomy...

High-frequency ultrasonography (HFUS) can help improve dermatofibrosarcoma protuberans (DFSP) recognition. We present three cases of DFSP in which a "jellyfish-like" sonographic pattern was a useful adjunct in formulating the diagnosis. In addition, we review all DFSP ultrasound images available in the literature.
