Pharmacokinetics and toxicity evaluation following oral exposure to bisphenol F.

Bisphenol F is a substitute material for bisphenol A and is widely used in household products as a raw material for polycarbonate resin, epoxy resin, and plastic reinforcement. It is known to be mainly used in food containers, thermal paper for receipts, and coatings for water pipes. In some countries, bisphenol F has been detected in drinking water and human urine samples.

[Clinicopathologic features of cases with negative pathologic results after endoscopic submucosal dissection].

Background/aims: Endoscopic submucosal dissection (ESD) is accepted as a standard treatment of early gastric cancer (EGC) and gastric adenoma. Occasionally, tumorous lesion is not found and pathologic discrepancies can occur after ESD. The aim of this study was to analyze the factors affecting the negative pathologic results after ESD.

A newly developed pericardial tuberculoma during antituberculous therapy.

Tuberculosis generally affects the respiratory tract. In developing nations, the pericardium is the most common location of extrapulmonary tuberculosis; however, tuberculous pericarditis rarely appears as a localized mass or tuberculoma. We present here a case of a 62-year-old woman with pericardial tuberculoma.

Dual pulsed-wave Doppler tracing of right ventricular inflow and outflow: single cardiac cycle right ventricular tei index and evaluation of right ventricular function.

Background And Objectives: The reliability and usefulness of the right ventricular (RV) Tei index (RTX) remains controversial because it has not been possible to simultaneously measure RV inflow and outflow. However, dual pulsed-wave Doppler (DPD) enables flow velocities to be obtained at different sampling sites simultaneously. In this study we evaluated the feasibility and reliability of RTX values obtained by DPD (RTX(DPD)).

Clinical characteristics, and laboratory and echocardiographic findings in takotsubo cardiomyopathy presenting as cardiogenic shock.

Purpose: Although takotsubo cardiomyopathy (TTC) has been reported to have an excellent clinical recovery, there are few data regarding clinical, laboratory, and echocardiographic findings in TTC presenting as cardiogenic shock. We aimed to assess the differences in these parameters between TTC presenting with and without cardiogenic shock.

Methods: Fifty patients were enrolled from the TTC registry database and divided according to the presence of cardiogenic shock.

Deglutition syncope associated with ventricular asystole in a patient with permanent atrial fibrillation.

Deglutition syncope is a situational syncope that is diagnosed only by a detailed history. We report deglutition syncope in a 62-year-old man, who had permanent atrial fibrillation. The patient had no structural or functional abnormalities of the esophagus.

Flash pulmonary edema in a patient with unilateral renal artery stenosis and bilateral functioning kidneys.

Flash pulmonary edema typically exhibits sudden onset and resolves rapidly. It generally is associated with bilateral renal artery stenosis or unilateral stenosis in conjunction with a single functional kidney. We describe a patient who presented with flash pulmonary edema treated by percutaneous therapy with stent implantation.

Intravascular ultrasound-guided troubleshooting in a large hematoma treated with fenestration using a cutting balloon.

Intramural hematoma formation is not a well-studied complication of percutaneous coronary intervention. We describe a patient with stable angina who developed an intramural hematoma during elective percutaneous coronary intervention (PCI) in the right coronary artery (RCA). Total occlusion with dense dye staining developed a long way from the distal RCA, near the posterior descending artery bifurcation site.
