Tonometers and infectious risk: myth or reality? Efficacy of different disinfection regimens on tonometer tips
2006
Purpose To evaluate the adequacy of common disinfection regimens for disposable tonometer tips and assess if disinfection of reusable prisms or the use of disposable tips is preferable. Methods We used disposable tonometer tips, using the same material and tip diameter of standard Goldmann tonometer prism. Strains of Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis and Candida albicans were tested according to the European standard guidelines for disinfectants test. Antimicrobial effectiveness of the following disinfection practices has been assessed: dry wipe, Minuten wipes (Alpros), soaking in 3% hydrogen peroxide, 0.5% benzalkonium chloride, and 0.5% Pantasepts for 1, 5, …
Antihypertensive and cardiovascular effects of combined blockade of renin-angiotensin system with ACE inhibitor and angiotensin II type 1 receptor bl…
2006
Background: In this study the effects of 24 weeks losartan and ramipril treatment, both alone and in combination, on blood pressure and left ventricular mass (LVM) and function,have been evaluated in hypertensives. Methods. 57 hypertensives with stage 1 and 2 essential hypertension were included. After 4 weeks run in, a randomized double-blind, 3 arm, double dummy, independent trial was used. All patients were randomly allocated to 3 treatment arms consisting of losartan (50 mg/daily), ramipril (5 mg/daily), and combined (losartan 50 mg/ramipril 5 mg/daily) for 24 weeks. LVM, LVM/h and other echocardiographic measurements, BUN, creatinine and clearance and potassium were determined after ru…

Therapeutic management of elderly hypertensives with concomitant ischaemic heart disease.
1992
CHARACTERISTICS OF ELDERLY HYPERTENSIVES: Hypertension is most prevalent in older patients and is associated with increasing morbidity and mortality with age. Elderly hypertensives often suffer from concomitant diseases, such as ischaemic heart disease, caused by age-induced modifications to the cardiovascular system, haemodynamic function and neurohormone activity. THERAPEUTIC MANAGEMENT: Therapeutic management of elderly hypertensives with concomitant ischaemic heart disease must take account of the pharmacodynamic and pharmacokinetic changes that occur in older subjects and drugs should be selected for their efficacy in both diseases. Since elderly subjects often metabolize drugs more sl…
Central obesity and hypertension: the role of plasma endothelin. Am J Hypertens
1996
Hypertension and central obesity are two conditions closely linked, but the mechanisms responsible for obesity-associated hypertension are still unclear. In the last few years, several studies addressed the role of endothelin-1 (ET-1) in the development and maintenance of hypertension. This study was designed to evaluate plasma ET-1 in normotensive and hypertensive central obese subjects compared with a lean healthy group. Our final goal was to analyze the relationship between plasma ET-1, blood pressure, and left ventricular structure and function in central obese subjects (both normotensives and hypertensives). ET-levels have been assessed by the radioimmunoassay method in 20 lean normote…
Effects of a short-term hypoenergetic diet on morphofunctional left ventricular parameters in centrally obese subjects
2000
BACKGROUND: We aimed to study centrally obese subjects without other diseases, to establish whether a short-term hypoenergetic balanced regimen is able to positively modify left ventricular (LV) patterns. METHODS: We studied 32 obese subjects (out of 52 recruited for this study) with central fat distribution and without associated diseases. Each subject had undergone a moderately hypoenergetic diet for a four-month follow-up period and had a regular loss in weight. Some relevant clinical and echocardiographic parameters were evaluated. Baseline data and those evaluated at the end of the follow-up period were used for outcome analysis. RESULTS: We found a considerable reduction in LV mass an…
L’obesità fattore o co-fattore di rischio?
2005
L’obesità rappresenta odiernamente uno dei problemi più rilevanti di salute pubblica al punto che l’Organizzazione Mondiale della Sanità (WHO) sostiene che essa debba essere considerata una vera e propria “epidemia globale” . L’obesità e le malattie ad essa correlate rappresentano nei paesi occidentali una delle cause principali di mortalità precoce e di morbilità. La prevalenza dell’obesità e del sovrappeso nei paesi industrializzati ed in quelli in via di sviluppo è stimata tra il 40% ed il 60%. Negli Stati Uniti d’America, i dati più recenti del National Health and Nutrition Survey (1999-2000) sottolineano come circa il 64.5% degli adulti (67.2% uomini e 61.9% donne) sono in sovrappeso e…
Micro-albuminuria in obese subjects: relationship among body fat distribution, blood pressure and left ventricular structure and function.
1998
OBJECTIVE: To evaluate the relationships among micro-albuminuria, blood pressure and measurements of left ventricular structure and function in centrally and peripherally obese subjects compared with members of a lean control group. METHODS: Centrally obese subjects were subdivided according to whether they had levels of micro-albuminuria higher than 30 mg/24 h (micro-albuminuric group) or lower than or equal to 30 mg/24 h (normo-albuminuric group). For all the subjects we measured heart rate, casual mean blood pressure (MBP), 24 h MBP, total cholesterol level, high-density lipoprotein cholesterol, lipoprotein (a) level, fasting immunoreactive insulin level, plasma renin activity, plasma al…
Obesità e rischio cardiovascolare.
2007
L’obesità rappresenta attualmente la più diffusa patologia da malnutrizione delle Società occidentali industrializzate e si associa spesso a svariate complicanze invalidanti sia mediche che chirurgiche. Essa è, inoltre, una condizione ad elevata prevalenza ed in continuo e costante incremento, al punto da essere etichettata come una “Epidemia globale”. Nella presente review sono stati analizzati i risultati degli studi più recenti che hanno individuato nella patologia del tessuto adiposo uno dei meccanismi più importanti nello sviluppo dell’aterosclerosi e delle manifestazioni cliniche ad essa connesse. Particolare riguardo è stato dato, oltre che alle evidenze epidemiologiche riguardanti i…
