Trypanosoma cruzi infection results in debilitating cardiomyopathy, which is a major cause of mortality and morbidity in the endemic regions of Chagas disease (CD). The pathogenesis of Chagasic cardiomyopathy (CCM) has been intensely studied as a chronic inflammatory disease until recent observations reporting the role of cardio-metabolic dysfunctions. In particular, we demonstrated accumulation of lipid droplets and impaired cardiac lipid metabolism in the hearts of cardiomyopathic mice and patients, and their association with impaired mitochondrial functions and endoplasmic reticulum (ER) stress in CD mice...

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is characterized by cystic dilation of the pancreatic duct, caused by mucin hypersecretion, with slow progression via the adenoma-carcinoma sequence mechanism. Mutation of GNAS at codon 201 is found exclusively in IPMNs, occurring at a rate of 41-75%. Recent advances in molecular biological techniques have demonstrated that GNAS mutation might play a role in the transformation of IPMNs after the appearance of neoplastic cells, rather than in the tumorigenesis of IPMNs...

BACKGROUND: Enterolithiasis is a sonographic sign defined by hyperechogenic foci within the - often distended - fetal bowel. OBJECTIVES: We report on a series of 20 cases with enterolithiasis diagnosed prenatally and illustrate the spectrum of associated malformations. METHOD: This was a retrospective study involving 20 fetuses with enterolithiasis at two large tertiary referral centers in Germany over a 17-year period (2000-2017). RESULTS: Median diagnosis was made with ultrasound at 18+2 weeks of gestation (IQR25,75: 14+5, 26+5)...

BACKGROUND: In adults and children, current guidelines recommend measuring the diameter of the vein before the insertion of central catheters, in order to match vein diameter with catheter caliber and thus reduce the risk of venous thrombosis. In the neonatal intensive care unit, central catheters are often used but the vein diameter is usually not considered. METHOD: We assessed the diameter of the most relevant deep veins in 100 newborns, using a strict protocol of ultrasound evaluation...

Primary thyroid malignancy is more frequent than secondary. This case report describes a colon lymphoma with unique thyroid metastasis. When a thyroid lesion appears in an extension study such as Positron emission tomography-computed tomography marked with 18F-2-fluoro-2-deoxy-D-glucose, it is recommended to perform an ultrasound. The correct study with ultrasound and cytology obtained through fine needle aspiration on thyroid lesion allowed to refine the diagnosis and provide the correct treatment.

The aim of this work is to verify applicability of the Kramers-Kronig relations between the attenuation coefficient and phase velocity of longitudinal acoustic waves in carbon fiber reinforced plastic (CFRP) composites in a finite megahertz frequency range. To measure these characteristics, the method of broadband acoustic spectroscopy with a laser source of ultrasound is used. We have experimentally shown that absolute attenuation in CFRPs is determined by both absorption in a polymer matrix and scattering on carbon fibers and gas pores of several tenths of microns in size...

In order to evaluate the influence of thermal stress on physiological parameters, and the oocyte quality of Girolando (n = 12) and adapted Pantaneira (n = 12) cattle, twelve sessions of ultrasound guided follicular aspiration (OPU) were performed, between January and November 2014 (during dry (May-September) and rainy season (October-April) in Brazil). The recovered cumulus-oocyte complexes (COCs) were selected and classified, according to quality, immediately after OPU. The oocytes were then stored in 3% paraformaldehyd before conducting immunofluorescence analysis under confocal microscopy to identify HSP70 and 90 proteins...

The objective of this literature review is to update the recommendations for clinical practice about the diagnosis of Pelvic Inflammatory Disease (PID), microbiologic diagnosis excluded. An adnexal pain or cervical motion tenderness are the signs that allow a positive diagnosis of PID (LE2). Associated signs (fever, leucorrhoea, metrorrhagia) reinforce clinical diagnosis (LE2). In a woman consulting for symptoms compatible with PID, a pelvic clinical examination is recommended (Grade B). In cases of suspected PID, hyperleukocytosis associated with a high C-reactive protein suggests a complicated PID or a differential diagnosis such as acute appendicitis (LE3)...

Multimodal primary treatment of localised adenocarcinoma of the stomach, the oesophagus and the oesophagogastric junction (AEG) was reviewed by a multidisciplinary expert panel in a moderated consensus session. Here, we report the key points of the discussion and the resulting recommendations. The exact definition of the tumour location and extent by white light endoscopy in conjunction with computed tomography scans is the backbone for any treatment decision. Their value is limited with respect to the infiltration depth, lymph node involvement and peritoneal involvement...

BACKGROUND: Contemporary selection criteria for men with prostate cancer (PC) suitable for active surveillance (AS) are unsatisfactory, leading to high disqualification rates based on tumor misclassification. Conventional biopsy protocols are based on standard 12-core transrectal ultrasound (TRUS) biopsy. OBJECTIVE: To assess the value of magnetic resonance imaging (MRI)/TRUS fusion biopsy over 4-yr follow-up in men on AS for low-risk PC. DESIGN, SETTING, AND PARTICIPANTS: Between 2010 and 2018, a total of 273 men were included...
