The prevalence of cirrhotic cardiomyopathy according to different diagnostic criteria.

Background And Aims: Recently published criteria by 2019 Cirrhotic Cardiomyopathy Consortium set a lower threshold for reduced ejection fraction to diagnose systolic dysfunction in cirrhotic patients, and stress testing was replaced by echocardiography strain imaging. The criteria to diagnose diastolic dysfunction are in general concordant with the 2016 ASE/EACVI guidelines and differ considerably from the 2005 Montreal recommendations. We aimed to assess the prevalence of cirrhotic cardiomyopathy according to different diagnostic criteria.

Liver metastases.

Liver metastases are a very common site of distant metastases. Detection and accurate characterization of liver metastases is of importance to guide therapy. A variety of imaging modalities such as US (including contrast agents), MDCT, MRI with liver -specific contrast agents and PET/CT are available for this purpose.

Capillary blood gas: a novel means of assessing free flap perfusion in an animal model.

Objective: To demonstrate that in comparison to implantable O(2) microelectrodes, capillary blood gas measurements represent a reliable, accessible, and easy method of identifying failing free flaps.

Study Design: Groin fasciocutaneous flaps were elevated in 10 rats and following venous occlusion, O(2) microelectrode measurements (pO(2) and flow), and capillary blood gas measurements (pO(2), pCO(2), pH, HCO(3)) were obtained at 10-minute intervals.

Results: Measurements with capillary blood gas paralleled measurements with O(2) microelectrodes.

Sonography of dermatofibrosarcoma protuberans of the groin.

Dermatofibrosarcoma protuberans (DFSP) is an uncommon tumor that arises from the dermis of adults. Its malignant potential is considered to be intermediate. Because the diagnosis of DFSP can frequently be suspected on the basis of physical examination reports on its sonographic appearance are rare.
