Torsade de pointes is a life-threatening, polymorphic ventricular tachycardia associated with prolongation of the QTc interval. Although torsade de pointes is found in many clinical settings, it is mostly drug induced. Similar problems have been described with nonsedating H1-selective antihistamines like terfenadine and astemizole. The increased risks of both H1-antihistamines were associated with exposure to supratherapeutic doses or concomitant exposure to the cytochrome P-450 inhibitors, ketoconazole, erythromycin and cimetidine. We report a 51-year-old woman with torsade de pointes and a long QTc interval caused by the combined use of terfenadine and itraconazole. After discontinuation of these drugs and treatments with electrical cardioversion and magnesium sulfate, torsade de pointes and prolonged QTc interval were no longer observed and she was discharged in good condition with a normal ECG. In conclusion, physicians should be aware that terfenadine and astemizole can cause torsade de pointes in rare cases.

It is often possible to diagnose a pheochromocytoma only when a disastrous cardiac complication like a hypertensive crisis, episodes of unexpected left ventricular failure, myocarditis, arrhythmias, myocardial infarction and sudden death appears secondarily. We revealed that a patient who had been treated with a reversible left ventricular systolic dysfunction with cardiogenic indeed had a pheochromocytoma. Upon initial admission, a 35 years old man had upper respiratory tract infection and abdominal discomfort. Blood pressure was 140/90 mmHg and EKG showed transiently paroxysmal supraventricular tachycardia. Eight hours after admission, he appeared to be in cardiogenic shock. Echocardiography showed extensive global hypokinesia with severe left ventricular systolic dysfunction. Following conservative management he progressively recovered normal cardiac function although we did not discern the etiology of the left ventricular systolic dysfunction. He was readmitted six months later due to episodic headache and high blood pressure. Fortunately, due to the history of reversible left ventricular systolic dysfunction with cardiogenic shock, we were able to quickly assess him as having a pheochromocytoma. The laboratory data and radiological findings were compatible with this tumor, which was subsequently successfully removed through surgery. We suggest that the diagnosis of pheochromocytoma should be considered in young patients presenting with acute heart failure of non-specific origin.

BACKGROUND AND OBJECTIVES: Coronary artery stenting actually shows a high efficacy in the treatment of coronary heart disease, but has the major limitation of restenosis. The ethylene-vinyl acetate copolymer (EVA), a biocompatible nondegradable copolymer, has been employed as a rate-controlling membrane in several drug delivery systems. Herein, the feasibility of an EVA-coated coronary stent was evaluated as a possible route for localized drug delivery. MATERIALS AND METHODS: A total of 15 rabbits were employed in this study. An uncoated stent was implanted into the non-diseased iliac artery in six rabbits, and an EVA-coated stent into a further nine. On the 30th day following the stent implantations, stented segments of the iliac arteries were removed for histological processing and morphometric analysis. RESULTS: The mean neointimal area of the uncoated and coated groups were 1.009 and 1.011 mm2 (p=0.56), respectively. No inflammatory cells were found in coated group. There were no apparent differences between the two groups. CONCLUSION: The results from this study have demonstrated that an EVA-coated coronary stent might be an appropriate method for the controlled-release of a drug.

Because the penetrating cervical tracheoesophageal injury may be associated with significant morbidity and mortality, it is important to choose the optimal method of diagnosis and management in patient with tracheoesophageal injury. We obtained a satisfactory result from repair of tracheoesophageal injuries using cardiopulmonary bypass. If the bleeding from the unidentified deep injury and the spread of infection could be controlled, the repair using CPB might increase the margin of safety during operation in the similar cases.
