Invited Commentary

This case series of 66 patients with 96 paired studies presents compelling evidence that abdominal ultrasound (US), in the right hands, provides more information about the intestinal and liver health of a neonate than plain abdominal film in the evaluation of necrotizing enterocolitis (NEC).1 Ultrasound seems to better detect pneumatosis intestinalis (PI), free air (FA), and portal venous gas (PVG). Additional information about bowel wall thickness, motility, perfusion, and the presence of extra-intestinal fluid collection (not evident on plain film) is captured.

Conclusion: We thus provide the proof of concept that in a mouse model of thromboembolic stroke with an intact skull, early ultrafast ultrasound can be indicative of responses to treatment and cerebral tissue fates following stroke. It brings new tools to study ischemic stroke in preclinical models and is the first step prior translation to the clinical settings.

Acute limb ischemia (ALI) and cannulation site bleeding are frequent complications of veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) and are associated with worse outcomes. The goals of this study were to assess our rates of ECMO-related ALI and bleeding and to evaluate the efficacy of strategies to prevent them, such as distal perfusion catheters (DPC) and ultrasound-guided cannulation.

In this study, 5% of VF arrest was due to PE: V fib is initial rhythm in PE in 3 of 60 cases. On the other hand, if the presenting rhythm is PEA, then pulmonary embolism is likely.  When there is VF in PE, it is not the initial rhythm, but occurs after prolonged PEA renders the myocardium ischemic.--Another study by Courtney and Kline found that, of cases of arrest that had autopsy and found that a presenting rhythm of VF/VT had an odds ratio of 0.02 for massive pulmonary embolism as the etiology, vs 41.9 for PEA.    ===================================MY Comment by KEN ...

Authors: Kok HP, Cressman ENK, Ceelen W, Brace CL, Ivkov R, Grüll H, Ter Haar G, Wust P, Crezee J Abstract The therapeutic application of heat is very effective in cancer treatment. Both hyperthermia, i.e., heating to 39-45 °C to induce sensitization to radiotherapy and chemotherapy, and thermal ablation, where temperatures beyond 50 °C destroy tumor cells directly are frequently applied in the clinic. Achievement of an effective treatment requires high quality heating equipment, precise thermal dosimetry, and adequate quality assurance. Several types of devices, antennas and heating or p...

This study reports the in vivo clinical feasibility of a voltage-sensitive ultrasound enhancing agent (UEA) for myocardial perfusion imaging. Four UEAs were injected into Sprague-Dawley rats while ultrasound images were collected to quantify brightness in the left ventricular (LV) cavity, septal wall, and posterior wall in systole and diastole.

ang The assessment of microvascular perfusion is essential for the diagnosis of a specific muscle disease. In comparison with the current available medical modalities, the contrast-enhanced ultrasound imaging is the simplest and fastest means for probing the tissue perfusion. Specifically, the perfusion parameters estimated from the ultrasound time-intensity curve (TIC) and statistics-based time–Nakagami parameter curve (TNC) approaches were found able to quantify the perfusion. However, due to insufficient tolerance on tissue clutters and subresolvable effects, these approaches remain short of reproducibilit...

Authors: Mejuto-Fernandez R, Iglesias-Garcia J Abstract Endoscopic ultrasound (EUS) was first described in 1986, with the aim of overcoming the problems affecting transabdominal ultrasound imaging, mainly problems related to the interposition of gas, and artifacts produced by bone or fat. Now, EUS can be considered as the best method for the analysis of pancreatic diseases, overtaking the diagnostic accuracy of computed tomography and magnetic resonance imaging. However, fundamental B-mode imaging is limited for the diagnosis of solid pancreatic lesions, because most of them are depicted as heterogeneous and hypo-e...

ConclusionL-RAMPS and modified Appleby procedure is a curative option for patients with distal pancreatic cancers that invade the celiac trunk and in whom the tumor biology is well controlled. A preplanned approach with 3D reconstruction accounting for organ displacement due to pneumoperitoneum optimizes surgical decision making and port placement for visual alignment caudally along the SMA.

Abstract Contrast-Enhanced Ultrasound as a Diagnostic Tool in Diseases of the Digestive Tract Abstract. Contrast-enhanced ultrasound is a good diagnostic tool in certain gastrointestinal diseases. Inflammation of the gastric and the bowel wall can often be distinguished from neoplastic alterations. Gastric and duodenal stenosis can be depicted with the use of oral contrast, and after stenting the patency can be documented. Abscesses are perfectly delineated, and after drainage the exact location of the tube and possible complications can be documented. In patients with Crohn's disease inflammatory activity and com...

Ultrasound-mediated cavitation of microbubble contrast agents produces high intravascular shear. We hypothesized that microbubble cavitation increases myocardial microvascular perfusion through shear-dependent purinergic pathways downstream from ATP release that is immediate and sustained through cellular ATP channels such as Pannexin-1.
