The Risk-based Treatment of Acute Pulmonary Embolism.

Unlabelled: Risk evaluation and prognostic stratification based upon clinical and radiological findings and new cardiac biomarkers, such as natriuretic peptides (NP) and troponins, represent key points in modern management of acute pulmonary embolism (PE). Literature evidence shows that normotensive PE with right heart dysfunction (RHD), defined as submassive PE, has poorer prognosis when compared to normotensive PE without RHD, defined as non-massive PE; thus whether submassive PE should be managed more aggressively and with closer monitoring represents the crucial question about acute PE treatment. Although the answer is yet unclear, the most recent guidelines address to thrombolysis as treatment choice in selected high risk patients with submassive PE.

[Prolongation of the Q-T interval and hyperkinetic ventricular arrhythmias probably induced by terfenadine use in liver cirrhosis patients].

The authors describe the prolongation of Q-T interval and secondary appearance of ventricular sustained ectopic beats in a 57 years old cirrhotic female treated for 4 days with antihistaminic drug (terfenadine) 240 mg/die/os. The pro-arrhythmic properties of terfenadine may be due to the quinidine-like mechanism of the drug and is strictly linked to the direct effect of the drug on H1 histaminergic receptors, which cause the prolongation of the myocardial cells action potential.

[Alcoholic hepatopathy, deficiency pathology and serum transaminases. Presentation of 2 clinical cases].

The authors describe two cases of Vit B1 and B6 deficiency in alcoholics with malnutrition. In the first case serum levels of AST and ALT, initially below norm became higher after Vit B1 and Vit B6 intake; the second, with AST and ALT above norm in previous months, had AST and ALT with normal activity during the disease. The authors suggest that normal activity of AST and ALT during alcoholic hepatopathy could be related to a depletion of Vit B1 and Vit B6.

[Increase of liver enzymes during treatment of myocardial infarct using intravenous nitro-derivatives].

A transitory serum elevation of hepatocellular enzyme alanine-aminotransferase (ALT) and gamma GT is reported during i.v. treatment with nitroderivatives of acute myocardial infarction.

[A case of wet beriberi].

The AA. report a case of thymine acute deficiency in a 35 year old chronic alcoholic and malnourished male, who was admitted to the hospital because of high-output heart failure, peripheral polyneuropathy, cortico-cerebellar atrophy (associated with RMN), ataxia and peripheral edema. The diagnosis of wet Beri-beri combined with Wernicke-Korsakoff syndrome was made and appropriate therapy with pulse daily dose of parenteral thymine instituted.
