Flecainide distribution in human tissues.

The distribution of antiarrhythmic drugs in human tissues may yield a better understanding of their therapeutic action and side effects. We report tissue distribution of flecainide in a patient who died suddenly while being treated chronically with the drug. Lungs showed the highest concentration of flecainide (143 micrograms g-1 wet tissue); liver, kidney and heart, in decreasing order, have good affinity for the drug. Flecainide was present also in the central nervous system in lower concentrations. The lowest concentration was found in the adipose tissue.

Severe reversible cardiac failure associated with methanol intoxication.

Methanol intoxication produces a well recognized clinical picture characterized by gastrointestinal, ocular and nervous system symptoms. The effect of poisoning on the cardiovascular system has not been well documented. We report the case of a 55 year old man whose acute methanol intoxication caused severe reversible cardiac failure. This represents the first description of an association between methanol toxicity and acute cardiac dysfunction in man.

Cardiac amyloidosis involving the conduction system and the aortocoronary neuroreceptors. Clinicopathologic correlates.

In a patient with cardiac primary amyloidosis with conduction disturbances and dynamic cardiocirculatory disorders, the specialized system of the heart and the hitherto neglected cardiac nerve plexus and annexed aortocoronary glomera were studied histologically. Amyloid deposition in the conduction system and in the nerves and neuroreceptors seemed to correlate with the dysrhythmic manifestations, and, respectively, with some undue responses to vasodilator therapy. The possible hazards deriving from involvement of the aortocoronary glomera in patients with amyloidosis have been pointed out accordingly.

Idiopathic recurrent sustained ventricular tachycardia responsive to verapamil.

The role of i.v. verapamil in the management of atrioventricular (AV) nodal reentrant tachycardias is well established (Schamroth et al., 1980). Generally however the drug is not very effective in recurrent ventricular tachycardia (VT) (Singh et al., 1983). Verapamil was recently demonstrated to be successful in terminating VT induced by programmed stimulation in only 1 out of 8 patients tested (Wellens et al., 1980). Conversely a few recent cases of verapamil responsive VT, mostly occurring in young people without obvious organic heart disease, have been reported (Belhassen, 1984; Klein, 1984; Delise, 1985; Ward, 1984; Lin 1983; German, 1983; Mason, 1983; Wu, 1981). We describe 3 clinical examples of idiopathic recurrent sustained VT responsive to verapamil. A careful analysis of our cases support the hypothesis of different pathophysiologic mechanism involved in the genesis of this unique arrhythmic entity.

Two false-negative responses to the ajmaline test in the Wolff-Parkinson-White syndrome.

Anterograde block in the accessory pathway with a short effective refractory period was observed after intravenous (IV) injection of 1 mg/kg of ajmaline in two patients with the Wolff-Parkinson-White syndrome. The possibility of a false-negative response to this test is discussed. Ajmaline is proposed as an emergency drug in the Wolff-Parkinson-White syndrome in the setting of atrial fibrillation with a very high ventricular rate.

[Negativity of myocardial scintigraphy with technetium-pyrophosphate in a case of primary cardiac amyloidosis].

We describe herein the case of a 62-year-old man affected by congestive heart failure of obscure origin, in which the clinical history, the electrocardiographic and echocardiographic findings were compatible with the diagnosis of amyloid cardiomyopathy. Cardiac catheterization disclosed a restrictive physiology. Tc-99m-pyrophosphate myocardial scintiscan was negative despite the markedly increased left ventricular wall thickness on echocardiographic examination. A definite diagnosis was obtained by means of endomyocardial biopsy.

[Diagnosis of bronchiolo-alveolar carcinoma].

Clinical and radiographic findings in bronchiolo-alveolar carcinoma are presented, with particular emphasis on differential diagnosis between diffuse and localized forms. A series is presented of 18 patients, observed in our Istitutes since 1980. Diagnostic role of radiology and bioptic techniques is discussed and the leading importance of broncoscopic biopsy is stressed.
