The "Neurocentric" Approach to Essential Hypertension: How Reliable is the Paradigm of Hyperkinetic Hypertension? A Focus on the Sympathetic Nervous …
2017
BACKGROUND: Clinic resting heart rate (RHR), is one of the cardiovascular parameters more easily measurable. In the general population RHR has been associated with total and cardiovascular mortality and higher rate of vascular events. OBJECTIVE: The case of essential hypertension is in some ways peculiar: in the past decades has often been attributed to hypertensive subjects higher values of RHR than healthy controls as a result of the effects of the different factors leading to the development of essential hypertension itself, first of all the presence of an increased tone of the sympathetic nervous system Methods: Several excellent articles debated the issue of autonomic dysfunction in es…

Hemorheological abnormalities in human arterial hypertension
2014
Blood rheology is impaired in hypertensive patients. The alteration involves blood and plasma viscosity, and the erythrocyte behaviour is often abnormal. The hemorheological pattern appears to be related to some pathophysiological mechanisms of hypertension and to organ damage, in particular left ventricular hypertrophy and myocardial ischemia. Abnormalities have been observed in erythrocyte membrane fluidity, explored by fluorescence spectroscopy and electron spin resonance. This may be relevant for red cell flow in microvessels and oxygen delivery to tissues. Although blood viscosity is not a direct target of antihypertensive therapy, the rheological properties of blood play a role in the…

Experiences with Blockade of the Renin System in Human Hypertension Using Converting Enzyme Inhibitor SQ 20,881 and Saralasin
1980
The development of agents which are capable of producing in vivo angiotensin II blockade has provided to investigators and clinicians alike the opportunity to determine and to quantify the extent to which the renin-angiotensin system participates in the maintenance of hypertensive states. High levels of plasma renin activity relative to the state of sodium balance have been documented in patients with malignant, surgically remediable renovascular hypertension and also in some patients with essential hypertension.1 The recent development of the angiotensin II analogue sar1-ala8-angiotensin II (saralasin) provided evidence to support the concept that these elevated renin levels are in fact pa…
Overexpression of nerve growth factor in peritoneal fluid from women with endometriosis may promote neurite outgrowth in endometriotic lesions
2011
To investigate the role of the nerve growth factor (NGF) in the endometriosis-associated innervation in the development of endometriosis- associated symptoms, 41 peritoneal fluid samples (PF) from patients with surgically and histologically proven endometriosis and 20 PF from patients with other gynecologic conditions were analyzed with Western blot and a novel in vitro model using dorsal root ganglia (DRG) to show neuronal outgrowth; endometrial cells also were analyzed. The results suggest that the PF of endometriosis patients and endometriotic lesions have neurotropic properties, because the Western blot analysis and the cell culture stainings showed NGF expression, and the neurite outgr…
Update on perioperative management of the child with asthma
2012
Asthma represents the leading cause of morbidity from a chronic disease among children. Dealing with this disease during the perioperative period of pediatric surgical procedures is, therefore, quite common for the anesthesiologist and other professionalities involved. Preoperative assessment has a key role in detecting children at increased risk of perioperative respiratory complications. For children without an optimal control of symptoms or with a recent respiratory tract infection elective surgery should be postponed, if possible, after the optimization of therapy. According to clinical setting, loco-regional anesthesia represents the desirable option since it allows to avoid airway ins…
