[The echocardiography in thalassemia major (author's transl)].

Echocardiographic findings were studied in seventeen subjects with beta-Thalassemia major in order to see whether cardiac lesions caused by iron were related to the age and chelating therapy. The results demonstrate that the alterations of the heart can be early detected by echocardiography. In fact no patient with echocardiographic alterations showed clinical signs of cardiac dysfunction and only four patients showed E.C.G. alterations. Moreover the thickening of posterior wall and left ventricular diastolic diameter were related to iron overload, as demonstrated by urinary excretion after desferrioxamine. Since the patients regularly treated with desferrioxamine were few and younger aged it is not possible in this study to show the positive effect of desferrioxamine treatment in preventing cardiac lesions due to iron overload.

[Electrophysiologic studies (auditory and somatosensory evoked potentials) in Friedreich's ataxia].

Auditory and somatosensory evoked potentials were recorded from 10 patients suffering from Friedreich's ataxia. All patients were subjected to audiological tests and EMG-ENG study. Acoustic evoked potentials recordings included brainstem acoustic evoked potentials and long latency components. Peripheral and central components of somatosensory evoked potentials were obtained by stimulating the median nerve at the wrist and elbow. Various abnormalities of the cortical components were observed in all patients for both acoustic and somatosensory evoked potentials. Analysis of brainstem acoustic evoked potentials and of the early components of somatosensory evoked potentials showed a different incidence of abnormalities. The main feature of brainstem acoustic evoked potential changes was the frequent absence of one or more waves; the greatest abnormalities occurred in patients whose disease was of long duration. Long latency components (N85) were significantly prolonged in all but one patient. There was often an absence or reduction of early somatosensory evoked potentials with normal or near normal latencies, even though cortical responses were markedly prolonged. The sensory conduction velocity between stimulation sites at wrist and elbow was normal in all patients. Clinically brainstem acoustic evoked potentials may prove to be a reliable means of monitoring the progression of the disease, while long latency components and somatosensory evoked potentials could be used as complementary procedures in early diagnosis.
