BACKGROUND: The condition called renal dysplasia is considered to be a frequent cause of chronic kidney disease in children. Formally, it is defined by histological parameters. In current nephrology practice, however, the appearance of the kidneys on ultrasound scanning is often used as a basis for the diagnosis. METHODS: The European Society for Pediatric Nephrology Working Group on Congenital Anomalies of the Kidney and Urinary Tract hypothesized that the current diagnostic approach with regard to renal dysplasia was not homogeneous...

BACKGROUND: Musculoskeletal findings in Sjögren's syndrome are arthralgia, arthritis, myalgia, myositis, fibromyalgia, and chronic fatigue. Enthesis zones are important in the formation of pain in the musculoskeletal system. Musculoskeletal ultrasound (US) may show subclinical enthesitis in the synovial joints and in the axial skeleton before joint swelling in inflammatory diseases characterized by arthritis. OBJECTIVE: In this study, we aimed to determine the presence of enthesopathy using the Madrid sonographic enthesitis index (MASEI) in patients with primary Sjögren's syndrome (PSS)...

BACKGROUND: Ultrasound is accurate in the detection of Crohn's disease. Our aim was to identify ultrasound parameters contributing to inflammatory disease activity, develop a simple score, and validate this score prospectively. METHODS: This study comprised 2 single-center investigations. The first was a retrospective study on a population that had received colonoscopies (as a gold-standard diagnostic) within 60 days of ultrasound. The second was a prospective study on 2 populations: patients requiring induction with adalimumab and patients on adalimumab maintenance therapy...

BACKGROUND AND AIMS: Fatty liver is a common feature of different types of liver diseases. The sensitivity and specificity of ultrasonography for diagnosing fatty liver are variable. A semi-quantitative ultrasound score, i.e., the ultrasonographic fatty liver indicator (US-FLI), is closely associated with metabolic/histological variables in patients with nonalcoholic fatty liver disease (NAFLD). The main aims of this study were to assess the diagnostic performance of US-FLI in detecting varying degrees of histological steatosis, and to examine the association of US-FLI with metabolic/histological parameters in 352 biopsied patients with various chronic liver diseases (173 with hepatitis C [HCV], 23 with hepatitis B [HBV], 123 with NAFLD and 33 with other etiologies)...

BACKGROUND: Laparoscopic surgery involves the creation of a carbon dioxide (CO2) pneumoperitoneum to facilitate a clear surgical view, which may result in an elevated intracranial pressure (ICP). Depending on the surgical area, steep Trendelenburg positioning may be used as well, further increasing the ICP. The objective of this study was to assess the effects of laparoscopic surgery on changes in ICP assessed by ultrasonographic measurement of optic nerve sheath diameter (ONSD), which is a generally accepted simple, reliable, and non-invasive ICP measurement technique...

BACKGROUND: Symptomatic muscle hernias are not uncommon in the lower extremities and are a rare cause of chronic leg pain. They are most commonly seen in the tibialis anterior muscle, occurring through fascial defects, usually after trauma. There are about 200 cases of muscle hernias described in the literature. The diagnosis is challenging as most of the patients present with non-specific chronic leg pain. Dynamic muscle ultrasonography at rest and at stress is often used for the diagnosis...

OBJECTIVE: The pathogenesis of non-alcoholic fatty liver disease (NAFLD) is attributed to a "multi-hits hypothesis" involving insulin resistance, oxidative stress and inflammation. Dipeptidyl peptidase-4 (DPP4) was identified as a novel adipokine capable of enhancing the"multi-hits". Hence, we investigated the association between plasma DPP4 activity and NAFLD in nondiabetic Chinese population. DESIGN AND METHODS: We performed a cross-sectional study using data from 1105 subjects (36-79years) in Guilin between 2015 and 2016...

Nathália Bragato, Naida Cristina Borges, Maria Clorinda Soares Fioravanti
Ultrasound is the imaging test of choice for renal evaluation, because it provides information about the position, size, shape, internal architecture and hemodynamics of the kidneys without harming the patient. In chronic kidney disease, the main findings observed in B-mode ultrasound images are increased cortical echogenicity, loss of corticomedullary differentiation, reduced renal volume and irregular renal contour, and when these changes are associated, they are indicative of end-stage renal disease. However, the cause of kidney disease cannot be determined by ultrasonography, but must be confirmed by means of biopsy, although the presence of ultrasonographic changes indicative of the end-stage of the disease may contraindicate this procedure...

Management of testicular rupture with a large tunical defect may not be feasible without excision of viable tissue. This study describes the use of a vascularized tunica vaginalis flap, without debridement of viable tissue, in four adolescents. Postoperative ultrasound showed good blood flow and 80% volume of the contralateral testis in two cases. Postoperative exam revealed normal exam and ultrasonographic appearance in three patients, the fourth was demonstrated to be small and undescended during evaluation of contralateral testicular torsion...

The purpose of this study was to build a mathematical model to predict the probability of axillary lymph node metastasis based on the ultrasonographic features of axillary lymph nodes and the tumor characteristics. We included 74 patients (75 axillae) with invasive breast cancer who underwent axillary ultrasonography ipsilateral to the tumor and fine-needle aspiration of one selected lymph node. Lymph node pathology results from sentinel lymph node biopsy or surgical dissection were correlated with lymph node ultrasonographic data and with the cytologic findings of fine-needle aspiration...

Feifei Wang, Xiaoping Zhu, Shaolin Ma
Diaphragm is the principal respiratory muscle. Diaphragm dysfunction resulting from mechanical ventilation, chronic cardiopulmonary disease, medicine, cardio-thoracic surgery, septic shock and chronic malnutrition predisposes to weaning failure from mechanical ventilation and prolongs intensive care unit (ICU) stay. Traditionally, the method of assessment of diaphragm structure and function was invasive, lacking specific, and was difficult to be used bedside. A number of recent studies have been suggested that ultrasonographic evaluation has been proposed as an accurate, safe and noninvasive method of quantification of diaphragm structure and function...

Ramón Almela, Wolf von Bomhard, Agustina Ansón, Ursula Mayer
BACKGROUND: Extraskeletal osteosarcomas (ESOSAs) are rare neoplasms in humans and animals. In cats, ESOSA has been reported to arise from orbital, ocular, intestinal, mammary and subcutaneous locations. Subcutaneous ESOSA occurs most commonly at sites used for vaccination including interscapular, dorsal lumbar or thigh areas. Previous reports of feline cases have not documented the use of advanced diagnostic imaging to exclude a primary bone tumour. OBJECTIVE: To describe the clinicopathological and advanced imaging findings of a subcutaneous ESOSA occurring in a metatarsal footpad of a cat and to report the one year follow-up status...

BACKGROUND: CLOVES syndrome is associated with somatic mosaic PIK3CA mutations and characterized by congenital lipomatous overgrowth, vascular malformations, epidermal nevi, and skeletal anomalies. Wilms tumor (WT) is a malignant embryonal renal neoplasm associated with hemihypertrophy and certain overgrowth disorders. After identifying WT in a child with CLOVES, we questioned whether ultrasonographic screening was necessary in these patients. METHODS: We retrospectively reviewed patients with CLOVES syndrome in our Vascular Anomalies Center at Boston Children's Hospital between 1998 and 2016 to identify those who developed WT...

BACKGROUND: Dermal melanocytic neoplasms are common in some even-toed ungulates (Artiodactyla), yet this entity has not been reported in the pygmy hippopotamus to date. Concurrent occurrence of multiple benign and malignant melanocytic neoplasms is unusual. Malignant transformation occurs in a small percentage of benign melanocytic tumours in people but this phenomenon has not been well documented in animals. OBJECTIVES: To report the diagnosis and treatment of concurrent dermal melanocytomas and malignant melanomas in a pygmy hippopotamus...
