An unusual presentation of mad honey poisoning: acute myocardial infarction.
An unusual type of food poisoning is commonly seen in the Black Sea coast of Turkey due to grayanotoxin containing toxic honey so called "mad honey" ingestion. In cases of toxication bradycardia and rhythm disturbances are commonly observed. Herein, we present a case of a patient who was admitted to the hospital because of acute myocardial infarction with normal coronary arteries after "mad honey" ingestion.

Free floating right atrial thrombus leading to acute pulmonary embolism.
The presence of right heart thrombi appears to increase the risk of mortality compared to the presence of pulmonary thromboemboli alone. The increased use of two-dimensional echocardiography has led to increased detection of these thromboemboli, particularly in patients with suspected or confirmed pulmonary emboli. The optimal management of the right heart thromboemboli remains unclear, but thrombolytic therapy with rt-PA appears to be rapidly effective in most patients resulting with complete resolution of the thrombus and improvement of pulmonary perfusion. Here, we present a case of free floating, worm-like thrombus in the right atrium which was lysed successfully by fibrinolytic therapy in a patient presenting with acute massive pulmonary embolism.

Dobutamine stress echocardiography (DSE) has been shown to be a very useful non-invasive technique for the detection of coronary artery disease. However, inadequate transthoracic images preclude the use of DSE in a significant proportion of patients. Transesophageal (TEE) or transthoracic contrast echocardiography (CE) can however overcome this limitation. ⋯ The kappa value for identical interpretation of a stress echocardiography study was nearly identical with both modalities 0.75 to 0.78. In poorly echogenic patients, DSE-CE is a valuable alternative for the detection of myocardial ischemia in comparison with DSE-TEE. Because DSE-CE is more comfortable than TEE, it should be used in patients with suboptimal transthoracic echocardiograms for the evaluation of coronary artery disease during DSE.

Atrial fibrillation with intermittent right axis deviation in the presence of complete left bundle branch block.
Left bundle branch block is usually associated with normal or left axis deviation. Rarely the ecg shows an LBBB with changing QRS morphology and changing axis deviation. We describe a case of atrial fibrillation with intermittent right axis deviation in the presence of complete left bundle branch block in an 84-year-old Italian woman in the Cardiology Unit.

Comparative Study
Combined NT-pro-BNP and CW-Doppler ultrasound cardiac output monitoring (USCOM) in epirubicin and liposomal doxorubicin therapy.
Chemotherapy with epirubicin is approved in women with breast cancer and is associated with a certain degree of cardiotoxicity. ⋯ Using the CW-Doppler USCOM a different hemodynamic response to epirubicin vs. liposomal doxorubicin is evident. Epirubicin leads to a significant upregulation of stroke volume and cardiac output, which is even more pronounced in the high-level NT-pro-BNP group, while liposomal doxorubicin does not change immediate hemodynamics. No deterioration of cardiac function using the real-time CW-Doppler ultrasound USCOM or an increase in NT-pro-BNP levels was evident during epirubicin or liposomal doxorubicin therapy.
