An Occult Cardiac Tamponade: Echocardiographic Diagnosis of Aortic Root Rupture in Infective Endocarditis.

Infective endocarditis (IE) remains a rare yet critically severe condition, representing a considerable diagnostic challenge, especially among patients with pre-existing structural heart anomalies. This report details the clinical journal of a 49-year-old male with a known bicuspid aortic valve who initially exhibited nonspecific symptoms, leading to rapid clinical deterioration and the emergence of uncommon complications. The patient experienced an aortic root rupture and pericardial tamponade, necessitating urgent surgical intervention.

Clinical Significance of Bioimpedance Spectroscopy in Critically Ill Patients.

Background: Early fluid resuscitation is a key aspect in the successful management of critically ill patients, but the optimal goal for volume control after the acute stage of critical illness remains unclear. This study aimed to evaluate the prognostic value of bioimpedance spectrometry for fluid management in critically ill patients.

Methods: In this prospective observational study, patients who consented to participate were screened within the first 24 hours of admission to a medical intensive care unit (ICU) from February 4, 2015, to January 31, 2016.

Mutagenicity study of butachlor and its metabolites using Salmonella typhimurium.

Butachlor is the most commonly used herbicide in Taiwan and many other countries. It has been reported to be an indirect mutagen and carcinogen in various in vitro assay systems. Previous investigation has also demonstrated that butachlor stimulates cell proliferation, transforms normal embryonic cells, and induces stomach tumors in Spraque-Dawley rats.
