The effects of isoproterenal (ISP) and methoxamine (MTX) infusion in 20 asymptomatic subjects with labile T wave were studied. In those treated with ISP the T wave showed an early negative trend and ...later became clearly positive in 5 subjects. In the majority of the subjects treated with MTX the T wave became positive. T wave changes match variations of both the ventricular gradient and, to a lesser degree, the QRS area. These changes were not related to heart rate or, in the subjects treated with MTX, to the baroreceptorial sensitivity deduced from the slope of the regression equation between R-R internal and systolic arterial pressure. The results of this study confirm the existence of a neurogenic mechanism affecting the electrocardiographic changes in T wave.

Describes the Italian experience of deinstitutionalisation in psychiatry. Highlights the differences between the Italian experience and psychiatric reforms in Europe and the US, where ...deinstitutionalisation has been reduced to dehospitalisation. The Italian form of deinstitutionalisation has developed as a complex of social processes. An example is given in the way in which mental health services have been organised in Trieste. Examines the reform law arising from the deinstitutionalisation process and the characteristics of its implementation. Deinstitutionalisation is no longer perceived as an aspect of the 'welfare crisis', but rather as a significant pointer to new post-welfare social policies. (Original abstract--Amended)
The results of a collaborative study involving about one third of the total DMD and BMD cases living in the Italian territory are reported. The analysis of the breakpoint frequency by intron revealed ...significant differences among regional groups of DMD patients (for introns 2, 11 and 50 in Sardinia and for introns 9 and 45 in northeastern Italy), whereas no regional differences were observed among regional groups of BMD patients. These differences involve the same Italian regions which previous studies, performed by different markers, identified as "genetically differentiated". The data support the possibility of a differential distribution among populations of some intronic sequences, facilitating the origin of deletion breakpoints within the dystrophin gene.
Sixteen subjects, mean age 59 +/- 18, 11 normal and 5 with coronary artery disease, all having premature ventricular and/or atrial beats in the standard resting electrocardiogram (ECG), were studied ...to analyse the chronobiologic parameters of these arrhythmias. Single cosinor analysis of the data obtained by 96-hour ECG performed according to the Holter system, demonstrated: A) significant circadian rhythm in heart rate for all the subjects, with acrophases occurring between 12.56 and 17.36; B) significant circadian rhythms of premature ventricular beats for the majority of the subjects, with acrophases distributed along the 24 hours; C) significant circadian rhythms in premature atrial beats for 8 subjects, with acrophases occurring between 04.24 and 18.12; D) a spectrum of significant ultradian rhythms in heart rate with various periodicities, both in normal and in coronary patients; E) significant ultradian rhythms in premature ventricular beats for 8 subjects with periods ranging from 5h 15' to 17h. Population mean cosinor analysis demonstrated: A) significant circadian group rhythm in heart rate for all the 16 subjects and for the group of 11 normal subjects; B) no significant circadian group rhythm for premature ventricular and atrial beats. These findings suggest that the study of the individual chronobiologic pattern of premature beats may help to optimize antiarrhythmic therapy.
A study of the relation between left ventricular ejection time (LVET) and arterial blood pressure (BP), was carried out in 26 healthy volunteers divided into 2 groups. A rise in BP was achieved in ...the first group of 2 subjects by venous infusion of 0.02% methoxamine solution. The heart rate was held constant by right atrial pacing and the arterial blood pressure was measured by catheterization of the right radial artery. A simultaneous recording of the electrocardiogram, the carotid arterial pulse and the arterial blood pressure tracings, was obtained. The relationship between LVET and the corresponding values of BP was examined by plotting LVET against BP. The second group of 24 subjects underwent a session of maximal isometric exercise. When the maximum of the effort was reached, the carotid arterial pulse tracing was recorded and the blood pressure of the arteria dorsalis pedis was measured by doppler technique. In both groups we plotted LVET against BP and HR. Simple and multiple regression equations were obtained. Our data show that LVET correlates with BP during the maximal isometric exercise and during venous infusion of methoxamine, suggesting that the normal values of systolic time intervals (STI) should be revised.

After a review of the literature on the subject, all IIIrd and IVth age patients admitted for acute abdomen to the Department of Surgical Pathology I of the University of Pavia between 1-1-1974 and ...31-12-1988 were studied. The various pathologies encountered in acute abdomen are considered on the basis of the results obtained, stress being laid on the clinical and diagnostic problems observed in these patients in relation to those of adult age. It is concluded that the study method used in the elderly gave good results with a mortality rate lower than that encountered in other studies on the subject.
Few papers deal with the chronobiologic characteristics of heart rate in neonates. A better knowledge of this topic could be useful under both clinical and therapeutical point of view. We studied the ...circadian and ultradian rhythms of heart rate in 10 healthy neonates (5 males and 5 females). Six of them (60%) show a well defined circadian rhythm of heart rate such as adult subjects even if with an obviously higher mesor and with acrophases dispersed throughout the 24 hours. We also demonstrated one or more ultradian rhythms of heart rate for each neonate. The most frequent have a period between 4 hours and 6 minutes and 4 hours and 36 minutes. These rhythms are out of phase with the world outside which is the best evidence that they are not imposed by some undetected external factors.

This research was aimed at checking the present composition of Salento wines, especially examining the evolution of malic acid contents. In the biennium 1992-94, a consistent number of industrially ...produced white, rose and red wine samples was analyzed. The data concerning the general characteristics proved to be comparable between the two vintages and to the ones reported by literature. The differences noticed on the contents of malic and lactic acids were discussed in relation to the kind of wine, the period of the samples, total acidity, pH and SO2
Scopo di questa indagine e' stato quello di verificare le caratteristiche compositive attuali dei vini della penisola Salentina, approfondendo in particolare lo studio dell'evoluzione dei contenuti di acido malico. Nel biennio 1992-94, e' stato analizzato un congruo numero di campioni di vino bianco, rosato e rosso prodotti dalle industrie. I dati relativi alle caratteristiche generali sono risultati confrontabili tra le due annate ed in linea con quelli riportati in letteratura. Le differenze rilevate sui contenuti degli acidi malico e lattico sono discusse in relazione al tipo di vino, epoca di prelievo dei campioni, acidita' totale, pH ed SO2
