Abstract
Tuberculosis keeps on representing a serious threat worldwide and one of the major challenge of our century. Different strategies have been developed in order to eradicate the disease, and particular attention is paid to children, who are at great risk for developing severe manifestations and poor outcome. Age at exposure, nutritional conditions and immune status can lead to great variability of disease expressions, with subsequent difficulties in making an appropriate and rapid diagnosis. Moreover, children coming from tuberculosis-endemic areas should be carefully evaluated for M. tuberculosis infection. Here we present a infrequent manifestation of extrapulmonary tuberculosis in a 13-years-old girl coming from Latin America: a superficial persistent cervical lymphadenopathy was associated with a totally asymptomatic retropharyngeal abscess. Diagnostic approach was discussed. Treatment consisted with a combination of surgical drainage of the abscess and a prolonged combined 6-month chemotherapy. The cervical lymphadenopathy disappeared and no relapses were found during the subsequent follow up.

Abstract
AIM To evaluate the benefit of endovascular peripheral revascularization on glucose control in patients with chronic limb ischemia. METHODS AND RESULTS Over a 12 month period, 61 patients (41 male, range 49-88 years of age) presenting with critical limb ischemia (CLI) were treated according to the Trans Atlantic Inter Society Consensus (TASC II) guidelines. After discharge, all patients were asked to measure their glucose level three times daily, and glycated hemoglobin was checked monthly up to 12 months, as well as to fill a questionnaire to assess their Quality of Life (QoL). The revascularization procedure was successful in 90% of cases. Glycemic control and glycated hemoglobin in 22 diabetic patients subgroup were significantly improved after the treatment and remained stable over the follow-up period. There was a significant improvement in QoL that increased steadily from the operation and to reach a plateau after six months. CONCLUSIONS Peripheral percutaneous angioplasty in subjects with CLI significantly improves glycemic control and ameliorates QoL. Revascularization positively effects also long-term diabetes control as well as QoL.

Abstract
OBJECTIVE Sympathovagal imbalance has been shown in acromegaly by indirect measurements of adrenergic tone. Data regarding direct measurement of sympathetic activity are lacking as yet. Aim of this study was to assess the adrenergic tone through direct recording of muscle sympathetic nerve activity (MSNA) in acromegalic patients. DESIGN Fifteen patients (age 26-66 years, eight women) with newly diagnosed active acromegaly without hyperprolactinaemia, pituitary hormone deficiencies, obstructive sleep apnoea and cardiac hypertrophy, and 15 healthy subjects matched for age, sex and body mass index were recruited. After evaluating anthropometric and echocardiographic parameters, anterior pituitary function, glucose and lipid metabolism, and measuring plasma leptin, direct recording of sympathetic outflow via the microneurographic technique was performed. RESULTS For similar anthropometric and metabolic parameters in patients and controls, HOMA index was significantly increased in the former (4·2 ± 2·39 vs 1·6 ± 0·19, P < 0·001). Surprisingly, this finding of insulin resistance was accompanied by a marked sympathetic inhibition (MSNA 18·3 ± 8·10 vs 37·3 ± 6·48 bursts/min, P < 0·0001, respectively in patients and controls). A reduction in plasma leptin (1·6 ± 1·04 vs 6·5 ± 2·01 μg/l, P < 0·0001) was also recorded in the patients. MSNA was positively correlated with leptin (P < 0·0001). CONCLUSIONS Newly diagnosed acromegalic patients without cardiac hypertrophy display a decreased sympathetic outflow in spite of insulin resistance. This finding might be related to hypoleptinaemia.

Abstract
Antiphospholipid-mediated endothelium perturbation plays a role in antiphospholipid syndrome (APS)-associated vasculopathy. Antiphospholipid antibodies activate endothelium both in vitro and in vivo experimental models by inducing a pro-inflammatory/-coagulant phenotype; the antibodies recognize beta2 glycoprotein I (beta2GPI) on human endothelial cells (EC) from different parts of the vasculature. In spite of such large in vitro evidence, few studies have addressed the issue whether or not a comparable endothelial perturbation might be detectable in vivo. We investigated several indirect ex vivo parameters of endothelial dysfunction: plasma levels of soluble adhesion molecules (sADM), soluble thrombomodulin (sTM), von Willebrand factor (vWF) and tissue plasminogen activator (t-PA) by solid-phase assays. The study included: patients with primary antiphospholipid syndrome (n=32), with the syndrome secondary to non-active systemic lupus erythematosus (SLE, n=10), six patients with persistent antiphospholipid positivity at medium/high titre without any clinical manifestation of the syndrome. Fifty-two age and sex matched healthy subjects have been enrolled as controls. In addition, circulating endothelial cells identified by flow cytometry and the brachial artery flow-mediated vasodilation (FMV) were evaluated in 26 patients (20 primary and 6 lupus syndromes) and 30 healthy controls. Plasma levels of soluble adhesion molecules did not differ from controls, while a significant increase in von Willebrand factor titres (P<0.05) was found. No significant difference was found regarding the number of circulating endothelial cells and flow-mediated vasodilation. As a whole, these findings do suggest that antiphospholipid antibodies per se are not able to support a full-blown endothelial perturbation in vivo. As shown in antiphospholipid syndrome experimental animal models, a two-hit hypothesis is suggested.

Abstract
A number of studies have shown that a smaller than normal nocturnal blood pressure (BP) decrease is associated with cardiovascular disease. However, no large prospective studies have examined the reliability of nocturnal dipping within individuals. The aim of our study was to investigate the short-term variability of nocturnal BP fall in a large cohort of patients with recently diagnosed essential hypertension. In all, 414 uncomplicated never treated hypertensive patients referred to our outpatient hypertension hospital clinic (mean age 46+/-12 years; 257 M, 157 F) prospectively underwent: (1). repeated clinic BP measurements; (2). routine examinations recommended by WHO/ISH guidelines; and (3). ambulatory BP monitoring (ABPM) twice within a 4-week period. Dipping pattern was defined as a reduction in the average systolic and diastolic BP at night greater than 10% compared to average daytime values. Overall, 311 patients (75.1%) showed no change in their diurnal variations in BP. Of the 278 patients who had a dipping pattern on the first ABPM, 219 (78.7%) confirmed this type of profile on the second ABPM, while 59 (21.3%) showed a nondipping pattern. Among 37 dipper patients with >20% of nocturnal systolic BP decrease (extreme dippers), only 16 (43.2%) had this marked fall in BP on the second ABPM. Of the 136 patients who had a nondipping pattern on the first ABPM, 92 (67.6%) confirmed their initial profile on the second ABPM, while 44 (32.4%) did not. Patients with reproducible nondipping profile were older (48+/-12 years) than those with reproducible dipping profile (44+/-12 years, P<0.05). These findings indicate that: (1). short-term reproducibility of nocturnal fall in BP in untreated middle-aged hypertensives is rather limited: overall, one-fourth of patients changed their initial dipping patterns when they were studied again after a few weeks; (2). this was particularly true for extreme dipping and nondipping patterns; (3). abnormalities in nocturnal BP fall, assessed by a single ABPM, cannot be taken as independent predictors of increased cardiovascular risk.

Compliance to hypertension guidelines in clinical practice: a multicentre pilot study in Italy. J Hum Hypertens 2002; 16:699-703.

Abstract
The aim of this study was to investigate the diagnostic approach to recently diagnosed hypertensive patients by primary care physicians in Italy and to find out whether general practitioners manage these patients according to 1999 WHO/ISH guideline recommendations. In total, 228 consecutive patients (117 men and 111 women, mean age 51+/-12 years) with recently diagnosed hypertension (<2 years) referred for the first time to six outpatient hypertension centres throughout Italy were included in the study. The primary care physicians' approach was evaluated during the specialist visit by a specific questionnaire containing detailed questions about diagnostic work-up and treatment made at the time of the first diagnosis of hypertension. At the study visit, 71% of the patients were on treatment with antihypertensive drugs and 18.7% of them had blood pressure (BP) values lower than 140/90 mmHg. A complete clinical and laboratory evaluation according to the minimum work-up suggested by the guidelines had been carried out in only 10% of the patients. A full physical examination had been performed in 60% of the patients, electrocardiogram in 54%, serum total cholesterol in 53%, glucose in 49%, creatinine in 49%, urine analysis in 46%, potassium in 42%, and fundus oculi in 19%. Additional investigations such as ambulatory BP monitoring, echocardiogram, carotid ultrasonogram, and microalbuminuria had been carried out in a minority of patients (21, 18, 9, and 3%, respectively). The impact on hypertension guidelines on patients' management in everyday primary care practice appears marginal. Thus, our findings indicate that the majority of general practitioners manage hypertensive patients according to a simple BP-based approach rather than a more integrated approach based on global risk stratification.

Abstract
BACKGROUND Left ventricular hypertrophy (LVH) and increased carotid intima-media thickness (IMT) represent independent risk factors for cardiovascular disease. OBJECTIVE To evaluate the prevalence of echocardiographic LVH and common carotid artery (CCA) intima-media (IM) thickening by different criteria in a large sample of hypertensive patients referred to our Hypertension Clinic. METHODS Echocardiograms and ultrasonographic carotid examinations have been performed in 640 consecutive hypertensives referred to our outpatient's hypertension unit. LVH was diagnosed using six different criteria, when left ventricular mass index (LVMI) exceeded (a) 100 g/m2 in women and 120 g/m2 in men, (b) 110 g/m2 in women and 125 g/m2 in men, (c) 110 g/m2 in women and 134 g/m2 in men, (d) 125 g/m2 in both sexes, (e) 47 g/h2.7 in women and 51 g/h2.7 in men, (f) 105 g/h in women and 126 g/h in men. Thickening of CCA IM was identified using three partition values; when IMT was (a) > or =0.8 mm; (b) >0.9 mm: (c) > or = 1.0 mm in both sexes. RESULTS Echocardiographic and ultrasonographic examinations of sufficient quality to be analysed were obtained in 611 patients (95.2%). Prevalence of LVH ranged from 18.6% (d) to 42.2% (f) and was significantly higher in men than in women by criteria (d) and (e), but slightly higher in women when using criteria (a) and (c). Eccentric hypertrophy was the most frequent type of LVH independently of the criteria used. Prevalence of IM thickening ranged from 14.7% (c) to 44.2% (a). Significant correlations between left ventricular mass (LVM)/body surface area, LVM/height and LVM/height2.7, and carotid IM thickness were found (r=0.41; p <0.0001; r=0.31; p <0.0001; r = 0.30; p <0.0001, respectively). CONCLUSION The prevalence of LVH and CCA IM thickening in hypertensive patients is markedly dependent on the partition values used to define these markers of target organ damage. Considering the pivotal role of LVH and CCA IM thickening in assessing the global cardiovascular risk profile in hypertensives, improved standardization in defining LVH and carotid IM thickening is needed.

Abstract
BACKGROUND Pilot educational meetings were conducted to (1) verify the support of hypertensive patients in this initiative; (2) test the knowledge of patients regularly followed-up in our Hypertension Centre Outpatient Clinic concerning problems related to hypertension; (3) improve patients knowledge about hypertension through a formal teaching session, (4) compare the knowledge of these patients with that of a control group. METHODS An invitation to participate in an educational program on hypertension was extended to 210 consecutive patients (group I ) followed-up in the outpatient clinic of our Hypertension Centre. Each meeting included four sessions: (1) an interactive phase with electronic devices aimed at evaluating the degree of information about hypertension by means of multiple-choice questionnaires, (2) a traditional teaching session, (3) an interactive phase to assess the compliance to treatment, and (4) a general discussion session. The control group (II) included 144 hypertensive patients referred for the first time to our Hypertension Centre. Before the initial visit the patients were asked to answer a questionnaire identical to that provided to group I during the meetings. RESULTS The meetings were attended by 183 out of the 210 patients in group I (participation rate = 87%). The answers to the questions were corrected as a percentage ranging from 73.7 to 95.6 in group I and from 43.9 to 74.7 in group II (p < 0.01). The provision of more detailed information about problems in hypertension was associated with better compliance to treatment and blood pressure control. (BP under treatment 138 +/- 14/83 +/- 7 mmHg in group I, 152 +/- 15/91 +/- 11 mmHg in group II; (p < 0.01). CONCLUSIONS Our data indicate that this type of educational approach is appreciated by patients (participation rate 87%) and that the level of knowledge about hypertension and compliance to treatment are greater in selected patients than in control patients.

Abstract
BACKGROUND Decision about the management of hypertensive patients should not be based on the level of blood pressure alone, but also on the presence of other risk factors, target organ damage (TOD) and cardiovascular and renal disease. OBJECTIVE To evaluate the impact of echocardiography and carotid ultrasonography in a more precise stratification of absolute cardiovascular risk. METHODS Never-treated essential hypertensives (n = 141; 73 men, 68 women, mean age 46 +/- 11 years) referred for the first time to our out-patient clinic were included in the study. They underwent the following procedures: (1) family and personal medical history, (2) clinical blood pressure (BP) measurement, (3) routine blood chemistry and urine analysis, (4) electrocardiogram, (5) echocardiogram, (6) carotid ultrasonogram. Risk was stratified according to the criteria suggested by the 1999 WHO/ISH guidelines. TOD was initially evaluated by routine procedures only, and subsequently reassessed by using data on cardiac and vascular structure obtained by ultrasound examinations (left ventricular hypertrophy (LVH) as left ventricular mass index (LVMI) > 134 g/m2 in men and > 110 g/m2 in women; carotid plaque as focal thickening > 1.3 mm). RESULTS According to the first classification 20% were low-risk patients, 50% medium-risk, 22% high-risk and 8% very-high-risk patients. A marked change in risk stratification was obtained when TOD was assessed by adding ultrasound examinations: low-risk patients 18%, medium-risk 28%, high-risk 45%, very-high-risk patients 9%. CONCLUSIONS The detection of TOD by ultrasound techniques allowed a much more accurate identification of high-risk patients, who represented a very large fraction (45%) of the patient population seen at our hypertension clinic. In particular, a large proportion of patients classified as at moderate risk by routine investigations were instead found to be at high risk when ultrasound examinations were added. The results of this study suggest that cardiovascular risk stratification only based on simple routine work-up can often underestimate overall risk, thus leading to a potentially inadequate therapeutic management especially of low-medium risk patients.

Abstract
BACKGROUND It has been generally accepted that educational programs can be beneficial in the treatment of a number of chronic diseases such as diabetes mellitus as well as of cardiovascular risk factors and hypertension. We organized a structured educational intervention aimed at 1) assessing the patient's baseline knowledge of hypertension, 2) verifying the short and long-term impact of this initiative on patient's education. METHODS We invited 174 consecutive patients referred to our hypertension outpatient clinic to participate in an educational meeting on hypertension. For organizational reasons, patients were divided into two groups, each attending a single meeting. Each meeting included four sessions: 1) in the first session a multiple choice questionnaire (nine questions, with answers collected by an interactive electronic system) was administered in order to evaluate patients' baseline knowledge of hypertension, 2) a traditional teaching session, 3) an interactive phase aimed at assessing the improvement of knowledge in which the same questions as in the first session were assessed again, 4) a general discussion session. At the end of the meeting a booklet on principal issues related to hypertension was given to each patient. In order to evaluate the long-term impact of this initiative on the patient's knowledge, 6 months later we invited the patients to answer to the same questions in a questionnaire sent to their home address. RESULTS One hundred thirty-three patients of the 174 invited attended the meeting and 111 (57 males, 54 females, mean age 53 +/- 13 years) completed the questionnaire after 6 months. The answers to the questions in the initial session were correct in a percentage ranging from 60 to 80% (mean 68%) and immediately after the teaching session this rate increased significantly (range 75-98%, mean 90%, p < 0.05 at least, in all questions). A similar good level of knowledge was maintained in the long term (percentage of exact answers ranging from 78 to 97%, mean 88%, p < 0.05 or p < 0.01 compared to baseline). CONCLUSIONS The findings of the present study show a positive short and long-term impact of a structured educational intervention on the patient's knowledge of issues related to arterial hypertension. The beneficial role on clinical outcomes such as blood pressure control and cardiovascular events will need future controlled trials.

Abstract
AIM The aim of the present study was to evaluate (1) the prevalence and patterns of left ventricular hypertrophy (LVH) and (2) the impact of blood pressure (BP) control, assessed by clinical and 24-hour ambulatory BP monitoring (ABPM) criteria on the persistence of LVH in a representative sample of treated patients attending our Hypertension Clinic. METHODS One hundred consecutive essential hypertensives (61 m/39 f, age 56+/- 9 years) regularly followed up by the same medical team (average period 52 months, 12-156 months) were included in the study and underwent 24-hour ABPM and complete echocardiographic examination. RESULTS Twenty-eight of the 100 patients were found to have LVH [left ventricular mass index (LVMI) >125 g/m(2) in men and >110 g/m(2) in women]; LVH was eccentric in 20 patients and concentric in the remaining 8. LVMI did not correlate with clinical BP values but only with ABPM values (mean 24 h systolic r = 0.34, p <0.01; diastolic r = 0.37, p <0.01). The prevalence of LVH in patients controlled according to clinical BP criteria (n = 43, BP <140/90 mm Hg) was 19%, in patients controlled according to ABPM criteria (n = 30, BP during daytime <132/85 mm Hg) 17%, and in those controlled with both criteria (n = 16) 6% (p <0. 01). CONCLUSIONS The results of this study suggest that the eccentric type of LVH is the prevalent pattern in chronically treated patients. The persistence of LVH is significantly dependent on BP levels achieved during treatment; indeed the prevalence of LVH is very low in patients with an optimal BP control, whereas it is elevated (37%) in uncontrolled patients.

Abstract
OBJECTIVES First, to evaluate the prevalence of left ventricular (LV) hypertrophy, LV concentric remodelling and microalbuminuria in a selected sample of treated hypertensive patients with effective and prolonged clinic blood pressure (BP) control (BP < 140/90 mmHg). Second, to compare the prevalence of these markers of organ damage in patients with and without ambulatory BP (ABP) control, defined as average daytime BP < 132/85 mmHg). DESIGN AND METHODS Fifty-eight consecutive hypertensive patients who attended our hypertension outpatient clinic over a period of 3 months and were regularly followed up by the same medical team were included in the study. Obesity, diabetes mellitus, history or signs of cardiovascular or renal complications and major noncardiovascular diseases were the exclusion criteria from the study. Each patient underwent 24 h ABP monitoring, echocardiography and 24 h urine collection for albumin measurement. RESULTS The prevalence of LV hypertrophy (LV mass index > 125 g/m2 in both sexes), LV concentric remodelling (relative wall thickness > 0.45) and microalbuminuria (urinary albumin excretion < 300 mg/ 24 h) in this selected group of patients (32 men, 26 women; mean age 53 +/- 9 years; mean clinic BP 122 +/- 9/ 78 +/- 6 mmHg) was markedly low (6.9, 8.6 and 5.1%, respectively). The 26 patients with effective ABP control (group I) were similar to the 32 patients without effective ABP control (group II) in age, gender, body surface area, clinic BP, smoking habit, glucose, cholesterol and creatinine plasma levels. Prevalence of LV hypertrophy, LV concentric remodelling and microalbuminuria was lower in group I than in group II (0 versus 12.9% P< 0.01, 7.7 versus 9.4% NS, 3.8 versus 6.2% NS, respectively). CONCLUSIONS This study demonstrates that nonobese, nondiabetic hypertensive patients with an effective clinic BP control have a very low prevalence of target organ damage and that LVH is present only in individuals with insufficient ABP control.

Abstract
The study was designed to evaluate whether the increase in left ventricular (LV) mass in essential hypertensives (H) is associated with a proportional increase in diameter of the left coronary artery (LCA) trunk. Twenty-six hypertensives, 14 with left ventricular hypertrophy (LVH) (left ventricular mass index [LVMI] > or =134 g/m2 in men and > or =110 g/m2 in women) and 12 without LVH, and 10 normotensive controls (C) underwent clinical laboratory and echocardiographic transthoracic examination. LV dimensions were measured according to the Penn convention and LV mass calculated by the formula of Devereux. The LCA main trunk was visualized by two-dimension short axis view at the level of the great vessels section, and the diameter measured as intima-intima distance at end-diastole. Hypertensives with and without LVH and C had similar age, sex, and body surface area distribution. LVMI was, by definition, significantly higher in H with LVH than in H without LVH and in C (144+/-21, 113+/-13, and 98+/-10 g/m2, P<.01), whereas the diameter of the LCA trunk was similar in all groups (0.48+/-0.1, 0.48, and 0.46 cm, respectively). There was no significant correlation between LVMI and LCA diameter in H (r = 0.21, P = not significant). The diameter of LCA trunk was significantly correlated only with BSA (r = 0.5, P<.01), LV end-systolic and end-diastolic diameters (r = 0.5 and r = 0.4, P<.05). Our data suggest that in H the increase in LVM is not associated with a concomitant increase of epicardial coronary artery diameter, and this finding may account in part for the impairment of coronary blood flow reserve in LVH.

Abstract
OBJECTIVE To evaluate in a selected population of subjects with a recent diagnosis of hypertension whether a blunted nocturnal fall in blood pressure is associated with more advanced cardiac and vascular damage. METHODS One hundred and eleven recently diagnosed and never-treated patients with mild essential hypertension underwent 24-h ambulatory blood pressure monitoring (ABPM), echocardiography and carotid ultrasonography. RESULTS The 78 patients with normal (> 10%) night-time fall in systolic blood pressure (SBP) and diastolic blood pressure (DBP) (dippers) were similar to the 33 patients with a small (< or = 10 %) fall (non-dippers) for age, sex, body surface area, smoking habit, clinic and 24-h blood pressure. There were no differences between dippers and non-dippers in left ventricular mass index (104 versus 105 g/m2), common carotid internal diameter (5.8 versus 5.9 mm), intima-media thickness (0.66 versus 0.64 mm) and carotid plaques prevalence (25 versus 29%). Furthermore, no differences were found in the correlation of daytime and night-time SBP and DBP with left ventricular mass and carotid wall thickness. When the 77 men and 34 women were analysed separately, similar results were obtained. CONCLUSION These results suggest that a blunted reduction in night-time blood pressure does not play a major role in the development of cardiovascular changes during the early phase of essential hypertension.

Abstract
OBJECTIVES First, to evaluate the prevalence of clinic blood pressure (BP) control (BP < or = 140/90 mm Hg) in a representative sample of treated hypertensive patients followed in our hypertension clinic. Second, to assess in a subgroup of these patients: (a) the proportion of BP control with both clinic blood pressure (CBP < or =140/90 mm Hg) and daytime ambulatory blood pressure (ABP) (< or =132/85 mm Hg) criteria, and (b) the prevalence of echocardiographic left ventricular hypertrophy (LVH) (left ventricular mass index, LVMI>125 g/m2 in men and >110 g/m2 in women). DESIGN AND METHODS Seven hundred consecutive hypertensive patients who attended our hypertension centre clinic during a period of 6 months and who had regularly been followed up by the same medical team were included in the study. BP was taken in the clinic by a doctor using a mercury sphygmomanometer with the participants seated. Seventy-four patients with similar demographic and clinical characteristics to the entire population of participants underwent complete echocardiographic examination and 24 h ABP monitoring. RESULTS During follow-up, 352 of the treated patients had clinic BP < or =140/90 mm Hg, 198< or =160/95 mm Hg and 150>160/95 mm Hg, indicating that BP control was satisfactory in 50.3%, borderline in 28.3% and unsatisfactory in 21.4% of the cases. In the subgroup of 74 patients, the proportion of individuals with satisfactory clinic BP control (CBP< or =140/90 mm Hg) was higher (50.0 versus 33.6%) than with satisfactory ABP control (daytime ABP values < or =132/85 mm Hg). LVH was found in 21 of the 74 patients (28.3%): 12 of them had unsatisfactory CBP control and 19 had unsatisfactory ABP control. LVMI did not correlate with CBP values but only with ABP values (mean 24 h systolic r = 0.47, diastolic r = 0.40, P<0.001; mean daytime systolic r = 0.45, mean daytime diastolic r = 0.39, P<0.001; mean night-time systolic r = 0.38, mean night-time diastolic r = 0.38, P<0.001). CONCLUSION This study demonstrates that hypertensive patients managed in a hypertension centre clinic have satisfactory CBP control in 50% of cases, but this rate seems to over-estimate the effective BP control during daily life. A large fraction of patients show persistence of LVH and this evidence of organ damage almost entirely concerns individuals with poor ABP control.

Abstract
Since cryptorchidism can cause infertility and early orchiopexy can improve fertility, we tried to determine whether medical and surgical treatment in the 1st year of life can improve testicular fertility. We concluded that this is the best time to treat cryptorchid tests.

Abstract
Arterial hypertension may be associated with altered left ventricular filling dynamics. The specific goal of this study was to evaluate whether short-term administration of the ACE inhibitor lisinopril in hypertensive patients with an altered diastolic pattern induced an improvement of left ventricular dynamics, assessed by the echocardio-Doppler technique, independently of effects on left ventricular mass. In a double-blind cross-over study 39 essential hypertensive patients with a ratio of peak early to peak atrial velocity (E/A) < 1 were randomized, after a run-in period of 2 weeks without any antihypertensive treatment, to receive lisinopril (20 mg once a day) and placebo for 4 weeks, respectively. At the end of both the run-in and the treatment periods, blood pressure and heart rate were measured and an echocardio-Doppler examination was carried out. The echocardio-Doppler evaluation was performed both at rest and at the peak of a hand-grip test (3 min at 30% of maximal strength). Left ventricular dimensions were obtained from two-dimensionally guided M-mode tracings using the criteria of the American Society of Echocardiography. Left ventricular peak filling rates and filling rate integrals were measured by a pulsed Doppler technique. Lisinopril caused a significant reduction in systolic and diastolic blood pressure at rest (-13/-9 mmHg vs baseline values, p < 0.05; -6/-4 mmHg vs placebo values, p < 0.05) and during isometric exercise (-17/-9 mmHg vs baseline period, p < 0.05; -6/-5 mmHg vs placebo, p < 0.05). Lisinopril did not induce any significant change in left ventricular structure and systolic function. All the left ventricular filling parameters considered (E velocity, A velocity, E/A ratio) both at rest and during isometric exercise did not significantly differ after lisinopril treatment when compared to those obtained in basal conditions and after placebo administration. This double-blind cross-over study demonstrates that short-term afterload reduction induced by lisinopril does not modify altered diastolic dynamics in hypertensive patients. Diastolic dysfunction of the left ventricle is a complex process influenced by a number of functional and structural factors and apparently cannot be significantly improved by short-term blood pressure reduction by antihypertensive therapy.

Abstract
AIM Left ventricular concentric remodelling defines a modified left ventricular geometry in the presence of a normal left ventricular mass; it is an early and frequent adaptation in arterial hypertension. The present study was designed to evaluate the extent of carotid structural changes in essential hypertensives with left ventricular remodelling. PATIENTS AND METHODS Two groups of hypertensive patients, who had never previously received anti-hypertensive treatment, 14 with left ventricular concentric remodelling (group I, relative wall thickness 0.48 +/- 0.02) and 48 with normal left ventricular geometry (group II, relative wall thickness 0.37 +/- 0.04) underwent clinical and laboratory examination, echocardiography, carotid artery ultrasonography and 24 h ambulatory blood pressure monitoring (ABPM). The left ventricular dimensions and mass were obtained according to the Penn convention. The intima-media thickness (IMT) of the posterior wall of both common carotid arteries was measured 5, 10 and 20 mm caudally to the bulb and the average value was used for analysis. RESULTS In both groups age (group I 44 +/- 9 years; group II 40 +/- 9 years), body surface area (group I 1.85 +/- 0.2 m2; group II 1.80 +/- 0.2 m2), duration of hypertension (group I 4.4 +/- 4; group II 3.8 +/- 3.9 years), metabolic parameters and smoking habits were similar. Both clinic and 24 h ABPM values were higher in group I (clinic 157 +/- 12/102 +/- 5; 24 h ABPM 145 +/- 10/95 +/- 7 mmHg) than they were in group II (clinic 146 +/- 11/97 +/- 5; 24 h ABPM = 134 +/- 10/87 +/- 8 mmHg, P < 0.01). The left ventricular mass index (LVMI) and IMT were found to be slightly but significantly greater in group I than they were in group II (LVMI 106 +/- 7 versus 98 +/- 12 g/m2, P < 0.05; IMT 0.68 +/- 0.13 versus 0.61 +/- 0.10 mm, P < 0.05). A significant correlation was found between LVMI and common carotid IMT in the whole group of hypertensive patients (r = 0.43, P < 0.01). CONCLUSIONS Our results indicate that left ventricular concentric remodelling does not represent the only early cardiovascular change in arterial hypertension but rather is associated often with carotid intima-media thickening.

Abstract
OBJECTIVE To investigate the association between increased left ventricular mass and the intima-media thickening of carotid arteries in hypertensive patients and the simultaneous involvement of the heart and the conductance vessels by the hypertensive process. METHODS Because no data are available concerning the ultrasonographic characteristics of large arteries in athletes with physiological increases in left ventricular mass, we measured the intima-media thickness (IMT) of the common carotid artery (CCA) in 14 normotensive subjects (group I, aged 22 +/- 4 years), in 14 borderline hypertensives (group II, aged 24 +/- 6 years) and in 14 Japanese wrestling players (group III, aged 23 +/- 4 years). The IMT of the posterior wall of the CCA was measured at 5, 10 and 20mm caudally to the bifurcation and the measurements were averaged. Left ventricular diameters and thicknesses of the interventricular septum and posterior wall were obtained from two-dimensionally guided M-mode tracings and measured according to the Penn convention. Left ventricular mass was calculated by the formula of Devereux. Left ventricular filling was measured by a pulsed Doppler technique. RESULTS Both systolic and diastolic blood pressure values were significantly higher in group II (145 +/- 7/91 +/- 5 mmHg) than they were in group I (116 +/- 11/75 +/- 5 mmHg) and in group III (120 +/- 8/78 +/- 6 mmHg). In athletes and hypertensives both the left ventricular mass index and the IMT of the CCA were significantly greater than they were in control subjects (80 +/- 12 g/m2 and 0.45 +/- 0.05 mm in group I; 106 +/- 15 g/m2 and 0.57 +/- 0.08 mm in group II; and 122 +/- 17 g/m2 and 0.55 +/- 0.05 mm in group III). The mitral early:late peak flow velocity ratio was significantly lower in group II (1.9 +/- 0.58) than it was in the other two groups (2.3 +/- 0.66 in group I and 2.6 +/- 0.64 in group III). CONCLUSIONS The results of our study suggest that both hypertension and physical training can induce parallel changes in cardiac and in arterial walls, and that physiological left ventricular hypertrophy in athletes is accompanied by a normal diastolic filling pattern in contrast to the pathological pattern found in hypertensives. Further investigation is required to explore possible differences in carotid structure and function between these two conditions.

Abstract
BACKGROUND The introduction of ambulatory blood pressure (ABPM) in the clinical practice has defined a new subgroup of hypertensive patients (pts) called "white coat" hypertensive pts. It has been reported that white coat hypertensive pts have less cardiac involvement than established hypertensive pts. This study was designed to examine the extent of cardiac and vascular involvement in pts with white coat hypertension and established hypertension. METHODS Fifty-four previously never treated pts with mild or moderate hypertension underwent a 24h ABPM and an echocardiographic and vascular ultrasonographic study in order to assess left ventricular anatomical parameters and the intima-media thickness of common carotid arteries. Left ventricular dimensions and mass were obtained according to Penn convention. The intima-media thickness of the far wall of both common carotid arteries was measured at 5, 10 and 20 mm caudally to the flow-divider; the average values were considered. RESULTS Twenty-eight pts (age 43 +/- 8 years) had an average daytime ABPM below 140/90 mm Hg ("white coat") and 26 pts (age 46 +/- 10) had a consistently elevated diastolic blood pressure. Both groups had similar office blood pressure (152 +/- 9/101 +/- 7 vs 155 +/- 10/103 +/- 6 mm Hg) body surface mass (1.79 +/- 0.23 vs 1.86 +/- 0.21 mq), sex (18M/20F vs 18M/8F), duration of hypertension, glycolipidic parameters and smoking habit. The daytime ABPM was (by definition) significantly higher in established hypertensive pts than in white coat hypertensive pts (145 +/- 11/97 +/- 4 vs 129 +/- 7/83 +/- 5 mm Hg, p < 0.001). Left ventricular mass index and intima-media thickness resulted significantly greater in established (119 +/- 1.7 g/m2; 0.70 +/- 0.11 mm) than in white coat hypertensive pts (99 +/- 16 g/m2; 0.60 +/- 0.1 mm, p < 0.002). The prevalence of left ventricular hypertrophy and cardiac remodeling was more frequent in established hypertensive pts (53%) compared to white coat hypertensive pts (7.7%). CONCLUSION The results of our study confirm that structural changes of left ventricle in white coat hypertensive pts are more limited than in established hypertensive pts and for the first time show that in white coat hypertensive pts the involvement of the conductance vessels is significantly lower than in established hypertensive pts.

Abstract
AIM The introduction of ambulatory blood pressure monitoring in the clinical practice has defined a new subgroup of hypertensive patients called white-coat hypertensives. It has been reported that white-coat hypertensives have less cardiac involvement than established hypertensive patients. This study was designed to examine the extent of cardiac and vascular involvement in patients with white-coat hypertension and established hypertension. PATIENTS AND METHODS We studied 82 patients with mild essential hypertension, never previously treated, using 24-h ambulatory blood pressure monitoring and an echocardiographic and vascular ultrasonographic study. Left ventricular dimensions and mass were obtained according to the Penn convention. The intima-media thickness of the posterior wall of both common carotid arteries was measured 5, 10 and 20 mm caudally to the flow-divider and the average value was used for analysis. RESULTS Of the 82 patients, 31 (mean +/- SD age 35 +/- 10 years) had average 24-h systolic/diastolic blood pressure values of below 132/85 mmHg (white-coat hypertensives) and 51 (aged 42 +/- 2 years) had a consistently elevated diastolic blood pressure. Both groups had similar body surface area (1.82 +/- 0.22 versus 1.81 +/- 0.22 m2), sex distribution (20 males and 11 females versus 32 males and 19 females), duration of hypertension, metabolic parameters and smoking habit. The 24-h ambulatory blood pressure monitoring values were, by definition, significantly higher in established hypertensives than in white-coat hypertensives (142 +/- 10/94 +/- 6 versus 127 +/- 6/79 +/- 4 mmHg, P<0.001). The left ventricular mass index and intima-media thickness were significantly higher in the established hypertensives (112 +/- 17 g/m2, 0.67 +/- 0.11 mm, respectively) than in the white-coat hypertensives (98 +/- 18 g/m2, 0.58 +/- 0.09 mm; P<0.001 for both). CONCLUSIONS The prevalence of left ventricular hypertrophy and cardiac remodeling was significantly more frequent in established hypertensives (51%) compared to white-coat hypertensives (19%). These confirm that structural changes in the left ventricle in white-coat hypertensives are more limited than in established hypertensives and show that in white-coat hypertensives there is significantly less involvement of the conductance vessels than in established hypertensives.

Abstract
The aim of this study was to measure intima-media thickness (IMT) of the common carotid artery (CCA) in patients with hypertrophic cardiomyopathy (HCM) and in hypertensive patients with left ventricular hypertrophy (LVH). We studied 73 subjects: 20 normotensive healthy subjects as control group (I); 20 patients with essential hypertension without LVH (II); 20 hypertensives with LVH (III), and 13 normotensive patients with HCM (IV). Each subject underwent a complete echocardiographic and vascular ultrasonographic study in order to assess left ventricular parameters and the IMT at the level of the CCA. Left ventricular mass index (LVMI) was significantly higher in groups III and IV than in groups I and II (156 +/- 18 and 157 +/- 31 vs. 94 +/- 14 and 98 +/- 10 g/m2, respectively, p < 0.01), while IMT was significantly greater in group III but not in the others [0.88 +/- 0.04 vs. 0.61 +/- 0.03 (I), 0.64 +/- 0.03 (II) and 0.61 +/- 0.04 (IV) mm, p < 0.01]. The correlation between LVMI and IMT was statistically significant within all the hypertensive patients (r = 0.48, p < 0.01) but not in the HCM group (r = 0.17, p = NS). The hypertensive patients with LVH showed structural alterations (related to hemodynamic and humoral factors) both at cardiac and vascular level while in patients with HCM the cardiac alterations (due to a genetic disorder) were not associated with changes at the level of the large arteries.

Abstract
The authors present their experience about intra-abdominal lymphangiomas and mesenteric cysts. The histologic evidence shows that these lesions are different. An exact histologic diagnosis is important because lymphangiomas are more invasive and relapsing than mesenteric cysts. Of 8 cases founded at laparotomy, 6 were lymphangiomas and 2 mesenteric cysts. Larger lesions were caused by lymphangiomas (mean, 11 cm vs 6 cm) when compared with mesenteric cysts. Complete resection was possible in all 8 patients, without recurrence after a mean follow-up of 4 years.

Abstract
BACKGROUND High resolution ultrasonography is a noninvasive technique that allows us to investigate the cardiovascular system, in particular the wall thickness and the lumen diameter of the arteries, with accuracy and reproducibility. METHODS We measured the intima-media thickness of the common carotid artery (CCA) and of its bifurcation (BIF) in 20 borderline hypertensive (age 24 +/- 4 years) and in 20 normotensive subjects (age 24 +/- 4 years), as a control group. Both carotid axes were scanned from different views (anterior, lateral, posterior) on a transversal and longitudinal section using a high resolution steerable linear array of 5 MHz. Carotid diameter and thickness were measured in the longitudinal section. CCA parameters were assessed 20 mm caudally to the flow divider. RESULTS In borderline patients blood pressure (147.8 +/- 10.5/90.7 +/- 6.6 mmHg) and left ventricular mass index (102.5 +/- 15.3 g/m2) were significantly higher than in normotensive subjects (blood pressure 120.5 +/- 11.5/78.0 +/- 5.4 mm Hg; left ventricular mass 90.5 +/- 14.3 g/m2). The intima-media thickness of both the CCA and BIF was significantly higher in borderlines than in normotensives (CCA 0.6 +/- 0.08 vs 0.4 +/- 0.05 mm, p < 0.001; BIF 0.7 +/- 0.08 vs 0.5 +/- 0.08, p < 0.001). In the whole population there was a statistically significant correlation between the carotid wall thickness and the left ventricular mass. CONCLUSIONS Our data show that ultrasonography provides direct evidence that in young borderline hypertensives the increased left ventricular mass is associated with vascular hypertrophy.

Abstract
Esophageal atresia without fistula is a rather uncommon malformation (about 8% of all esophageal atresias); its surgical correction is sometimes difficult because of the long gap between the two pouches. When a delayed anastomosis cannot be performed, it is necessary to perform a colon interposition. In one patient operated with retrosternal esophageal-colon-plasty a second operation was needed to correct a symptomatic reflux causing dysphasia and severe aspiration pneumonia. The distal end of the colon was tapered around a chest tube; then a submucosal gastric tunnel was prepared, and the tapered colon was pulled through it and anastomosed to the gastric lumen. The child showed no evidence of gastrocolic reflux in the three years following the operation and is today healthy. Radiologic and scintigraphic examinations, performed ten months after the operation, showed the good canalization of the interposed colon and the continence of the antireflux anastomosis.

Abstract
High resolution ultrasonography allows the accurate and reproducible measurement of thickness and lumen diameter of carotid arteries. We investigated Common carotid (CCA) and bifurcation intima-media thickness in 40 hypertensive patients, 20 without left ventricular hypertrophy (LVH) (age 42 +/- 10 years) and 20 with LVH (age 44 +/- 12 years), all free from other important cardiovascular risk factors. Both carotid axes were scanned from different views (anterior, lateral, posterior) on traversal and longitudinal section, using a high resolution steerable (HRS) 5.0 MHz linear array. Carotid diameter and thickness from longitudinal section were measured. CCA parameters were taken 20 mm caudally to flow divider. Using the B-mode as a guide we assessed LVH presence with M-mode technique when left ventricular mass index (LVMI) > or = 135 g/m2 for men and > or = 110 g/m2 for women. In hypertensive patients with LVH, left ventricular mass was significantly higher than in those without LVH (156 +/- 38 vs 98 +/- 10 g/m2, p < 0.01). Even blood pressure was significantly higher in hypertrophic group (172 +/- 21/108 +/- 9 vs 158 +/- 11/99 +/- 12 mmHg, p < 0.01), while there was no difference in serum glycemia, triglycerides, total and fractioned cholesterol levels. The intima-media thickness scanned in both CCA and bifurcation resulted significantly higher in hypertensives with LVH (CCA: 0.85 +/- 0.02 mm vs 0.65 +/- 0.02 mm; BIF: 0.93 +/- 0.04 mm vs 0.70 +/- 0.03 mm, p < 0.01). We also noticed a statistically significant correlation between carotid wall thickness and left ventricular mass index.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
PURPOSE World Health Statistic Annuals between 1973 and 1982 show that mortality from cardiovascular and coronary heart disease fell significantly during this period. Against this background, the present review analyses results from trials of antihypertensive therapy in elderly hypertensives. STUDY SELECTION The review examined available trials specifically devoted to testing the hypothesis that antihypertensive treatment in the elderly hypertensive can lead to a decrease in morbidity and mortality. RESULTS OF DATA ANALYSIS Different, randomly allocated, controlled trials have shown that a pharmacological reduction in blood pressure can reduce the incidence of cardiovascular events in the elderly to a similar extent as in young and adult hypertensive patients. Recent reviews have indicated, in contrast to previous suggestions, that the available antihypertensive agents do not have an age-dependent effect. Therefore the choice of antihypertensive therapy is more dependent on previous use or the presence of concomitant diseases. CONCLUSIONS Arterial hypertension is a risk factor in the elderly which can be reduced with pharmacological intervention.

Abstract
Down's syndrome is the most frequent chromosomal anomaly in humans and sometimes is associated with anorectal anomalies. The anorectal malformations include many varieties of anatomical anomalies, which are often difficult to evaluate. The Authors believe preoperative CT or MRI of the pelvis, together with other clinical and radiological examination to be a valid mean in the preoperative prognostic evaluation. In this study they analysed the association of anorectal malformations and Down's syndrome and the absence of a genito-urinary or perineal fistula.

Abstract
Since the advent of the Doppler color flow echocardiography, the presence of a small degree of insufficiency of the cardiac valves has been detected with relative frequency in structurally and functionally normal hearts. Data about this so-called 'physiological' regurgitation are presently available only in normotensive subjects and athletes. We therefore studied the prevalence of this phenomenon in a group of patients with essential hypertension compared to a population of normotensive subjects. To this purpose, a Doppler color flow echocardiographic study was performed in 130 essential hypertensive patients (72M/58F; age 44.2 +/- 13.5 years; BP 154.3 +/- 12.8/98.3 +/- 7.1 mm Hg) without any evidence of left ventricular hypertrophy or cardiopathy and in 100 normal subjects (59M/41F; age 41.2 +/- 14.8 years; BP 119.1 +/- 8.1/79.2 +/- 8.1 mm Hg). We conclude that in patients with essential hypertension the physiological regurgitant jets are present in one or more cardiac valves; moreover, the regurgitation of the mitral and aortic valve is found with more frequency than in the normotensive control group (36.1 vs. 27.0% and 17.7 vs. 11.0%, respectively). These data suggest that the increased afterload of the left ventricle may play an important role in the pathogenesis of even minor degree of insufficiency of the cardiac valves. As this finding does not appear to have a pathological relevance, the main clinical implication of this study is that it is not advisable to create a jatrogenic heart disease in the hypertensive patients routinely screened by the echo-Doppler technique.

Abstract
High-resolution ultrasonography is a noninvasive technique that allows to investigate the cardiovascular system, in particular the wall thickness and the lumen diameter of the arteries with accuracy and reproducibility. We measured the intima-media thickness of the common carotid artery (CCA) and of its bifurcation (BIF) in 40 patients with essential hypertension, 20 of them with left ventricular hypertrophy (LVH; age 42 +/- 10 years) and 20 without LVH (age 44 +/- 12 years); no other major cardiovascular risk factor was present in all the patients. Both carotid axes have been scanned from different views (anterior, lateral, posterior) on a transversal and longitudinal section using a high-resolution steerable linear array of 5.0 MHz. Carotid diameter and thickness were measured in the longitudinal section. CCA parameters were assessed 20 mm caudally to the flow divider. In patients with LVH, blood pressure (172 +/- 21/108 +/- 9 mm Hg) and left ventricular mass index (156 +/- 38 g/m2) were significantly (p < 0.01) higher than in patients without LVH (blood pressure: 158 +/- 11/99 +/- 12 mm Hg; left ventricular mass index: 98 +/- 10 g/m2), while there was no difference in serum glycemia, triglycerides, total and fractioned cholesterol levels. The intima-media thickness of both the CCA and BIF was significantly higher in the hypertensives with LVH (CCA: 0.85 +/- 0.02 vs. 0.65 +/- 0.02 mm; BIF: 0.93 +/- 0.04 vs. 0.70 +/- 0.03 mm, p < 0.01). There was a statistically significant correlation between the carotid wall thickness and the left ventricular mass index.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The study of anorectal malformations has considerably improved over the last years also thanks to the use of such diagnostic techniques as CT and MR imaging, which allow a better knowledge of perineal region anatomy and the demonstration of the development of sphincteric structures. The most important diagnostic phase for the identification of anorectal malformations consists in the detection of rectal fistulas. The authors report on their experience with barred water-soluble contrast enema in the study of anorectal anomalies. Over 2 years, 23 patients with anorectal malformations (10 males and 13 females) previously submitted to colostomy, were studied with this method. Fistulas were detected in 21 cases; in the extant 2 patients (both females affected with Down syndrome), no fistulas were detected, not even at surgery, which was posterior sagittal anorectoplasty according to Peña-De Vries. In our experience, the most frequent anomalies were recto-bulbo-urethral fistula in males and low recto-vaginal fistula in females. The authors suggest the use of this method as a routine diagnostic examination, because of its proven reliability.

Abstract
The aim of this study was to analyze the acute and chronic effects of oral verapamil on diastolic function indices, derived from Doppler echocardiography and left ventricular (LV) dimensions and mass, assessed by M-mode echocardiography, in hypertensive patients (pts). Twelve essential hypertensive pts without LV hypertrophy were studied in basal conditions and 1) after a single oral administration of verapamil 160 mg and placebo, in double blind protocol and 2) over chronic treatment (six months) of verapamil 240 mg/day. At baseline the ratio between early and atrial-induced transmitral velocities (E/A ratio) was lower in pts than in 12 age-matched normal subjects (1.0 +/- 0.3 vs 1.5 +/- 0.3, p less than 0.01). Acute verapamil administration significantly decreased arterial blood pressure (162 +/- 26/101 +/- 15 to 142 +/- 12/88 +/- 7 mmHg, p less than 0.01) after two hours and increased the E/A ratio to 1.26 +/- 0.3 (p less than 0.05) after three hours. No change in ventricular dimensions or heart rate was observed. After chronic therapy we found a further increase in the E/A ratio (1.49 +/- 0.3, p less than 0.01) in 10 responder pts. The LV mass index, which was higher than in normal subjects before the treatment (118 +/- 16 vs 91 +/- 11 g/m2, p less than 0.01), was significantly reduced (100 +/- 17 g/m2, p less than 0.05 vs basal, ns vs normal subjects). Our results demonstrate that acute administration of verapamil only partially improves the abnormal indices of diastolic function in hypertensive pts, whereas chronic treatment, by reducing left ventricular mass indices and blood pressure to normal values, can completely normalize the indices of LV diastolic filling.
