LA STORIA
No full textNel capitolo del libro si prende in esame l'evoluzione della chirurgia vascolare con la successiva nascita delle tecniche mininvasive endovascolari. Si ripercorrono le tecnologie innovative messe a punto dai pionieri di queste tecniche ed in maniera particolare si descrive la nascita e l'evoluzione della tecnica di trattamento endovascolare degli aneurismi dell'aorta addominale messa a punto da J.C. Parodi
Plasma cortisol concentration following breakfasts of different composition in healthy subjects
No full textWe measured plasma cortisol concentrations following breakfasts of different fat:carbohydrate ratio in 23 healthy subjects. A meal-related peak of plasma cortisol concentration was not found, as well as any difference in plasma cortisol levels following the two meals. Since the two meals elicited plasma glucose and plasma insulin levels which were significantly different, it is suggested that plasma cortisol is not acutely affected by ambient glucose and insulin concentrations. The same results were found when the study group was subdivided in nonobese (n = 13) and obese (Body Mass Index greater than n = 10), thus confirming the previous statement in the presence of different body weights

[Carotid endarterectomy with placement of a PUR (polyurethane) patch]
No full textIn this study, 40 patients who underwent surgery for cerebro-vascular insufficiency were considered. Carotid endarterectomy was the procedure of choice in all of the patients; the arteriotomy was always closed using a PUR patch, a new material that, for its chemical and physical characteristics seems to be a good alternative to PTFE. All of the patients underwent surgery under loco-regional anesthesia, allowing a perioperative monitoring of the neurological status through the patient's active collaboration. During the postoperative period, non local or systemic pathology related to the use of the patch has been observed. During the short and half term follow-up, the patients underwent echo-Doppler of the supra-aortic trunks that didn't show either false aneurysms or thrombosis on the patch surface
IL TRATTAMENTO CHIRURGICO DELLA GRANDE OBESITA'
No full textI primi interventi chirurgici per il trattamento della obesità patologica vedono la luce intorno agli anni 60 e rappresentano il tentativo di dare una risposta a
questo problema che negli Stati Uniti, dove nacque questo tipo di chirurgia,
coinvolgeva fin da allora un elevato numero di soggetti.
Gli Autori passano in rassegna i diversi tipoi di interventi, evidenziandone sia i punti forti che quelli deboli, soprattutto in relazione alla singolarità di ogni paziente
Evolution of carotid atheromatous lesions in endarterectomized patients
No full textA noninvasive follow-up using duplex ultrasonography was conducted in 128 patients who had undergone carotid endarterectomy from January 1987 to December 1988. Repeated scans of the operated area revealed a distinct increase in thickened ultrasonographic features (32% vs 8%), and a stenosing lesion was detected in 8 patients. There was also a parallel increase in the number of subjects with thicknesses of the intima adjacent to the endarterectomy area exceeding 2.5 mm. In 7% of cases, dilatation was detected in the operated area and in 27% the margin of the area was raised. The study also dealt with the contralateral carotid artery, where a progression of atheromatous involvement was observed with an increased number of cases of hemodynamically significant stenosis and 3 cases of occlusion. Periodic duplex ultrasonography in endarterectomized patients proves useful for the early detection of hemodynamically significant stenoses or of structural features potentially capable of generating emboli
A discrepancy between the effects of a single oral dose of captopril on blood pressure, plasma renin activity, and serum angiotensin-converting enzyme levels
No full textThe effects of a single oral dose (100 mg) of the angiotensin-converting enzyme (ACE) inhibitor, captopril (SQ 14,224), on blood pressure (BP), plasma renin activity (PRA), plasma aldosterone (PA), and serum ACE were investigated in 18 patients with essential hypertension (EH) and in 4 with renovascular hypertension (RVH). in most patients, SQ 14,225 caused a significant reduction of BP during the subsequent 6 h, particularly in RVH patients. A significant correlation between basal PRA levels and BP reduction was observed only by considering all the patients together. After ACE blockade, a significant increase of PRA was observed in RVH and in normal-renin EH patients, but not in EH patients with lower PRA. Maximal serum ACE inhibition (over 50%) occurred after 2 h but diminished after 4 h and 6 h, whereas the BP decrease persisted for 6 h. After 3-day treatment with indomethacin (six patients) captopril's antihypertensive action was blunted, despite a reduction of baseline PRA levels and of captopril-induced PRA elevation. The antihypertensive effects of SQ 14,225 in low-renin EH patients, the lack of effect of ACE blockade on renin secretion in these patients, and the reduction of the antihypertensive effects of SQ 14,225 after indomethacin refute the interpretation of purely angiotensin-related antihypertensive mechanism
