Available in PDF, EPUB and Kindle. Book excerpt: It is a great honor and pleasure for me to introduce this book; an honor, because of the scientific renown and authority of the investigators who have edited the volume and contributed the chapters; a pleasure, because my own long-lasting interest in the baroreflexes has always gone in the same directions as those along which the authors of this book have conceived and organized their work. It is particularly meaningful, in my opinion, that the very title of this volume underlines the integrative functions and the clinical aspects of baroreceptor reflexes. Under the aspect of integration, it is more and more apparent that baroreceptor reflexes, though preponderantly influencing cardiovascular functions, are not limited to cardiovascular control. Their influence on respiration has been well known since the earliest studies on baroreflexes, and wider influences have more recently been shown, e. g. , on hormone release, on sleep and vigilance, and on emotional behavior. Even within the scope of cardiovascular regulation, the integrated action of baroreflexes is not only directly exerted on the heart and blood vessels, but is also exerted through more devious but no less important routes, such as renin release from juxtaglomerular cells and sodium and water reabsorption by the renal tubules.

Available in PDF, EPUB and Kindle. Book excerpt: Nerve endings in the walls of the carotid sinuses and the aortic arch transduce arterial pressure changes and provide the central nervous system with a steady stream of encoded information. On the basis of this information, efferent autonomic neural activity is modulated finely, and the neurohumoral milieu of the heart and the blood vessels is adjusted on a second-to-second basis. The arterial baroreflex may be the most important of the cardiovascular control mechanisms, because the baroreflex, above all other reflex mechanisms, is the one whose speed is most adequate to respond rapidly to the abrupt transients of arterial pressure that occur in daily life. This volume presents the many experimental methods available for use in humans that have been recently developed. Some are ingenious and yield results that earlier might have been thought impossible to obtain from human volunteers. Development of these new methods has increased the scientific credibility of human baroreflex research, and this work discusses the advances made in these studies. It clearly describes the existing deficiencies in the understanding of baroreflex mechanisms, and suggests methods for future research in this developing field.

Download or read book Neural Control of Renal Function written by Ulla Kopp and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The kidney is innervated with efferent sympathetic nerve fibers reaching the renal vasculature, the tubules, the juxtaglomerular granular cells, and the renal pelvic wall. The renal sensory nerves are mainly found in the renal pelvic wall. Increases in efferent renal sympathetic nerve activity reduce renal blood flow and urinary sodium excretion by activation of α1-adrenoceptors and increase renin secretion rate by activation of β1-adrenoceptors. In response to normal physiological stimulation, changes in efferent renal sympathetic nerve activity contribute importantly to homeostatic regulation of sodium and water balance. The renal mechanosensory nerves are activated by stretch of the renal pelvic tissue produced by increases in renal pelvic tissue of a magnitude that may occur during increased urine flow rate. Activation of the sensory nerves elicits an inhibitory renorenal reflex response consisting of decreases in efferent renal sympathetic nerve activity leading to natriuresis. Increasing efferent sympathetic nerve activity increases afferent renal nerve activity which, in turn, decreases efferent renal sympathetic nerve activity by activation of the renorenal reflexes. Thus, activation of the afferent renal nerves buffers changes in efferent renal sympathetic nerve activity in the overall goal of maintaining sodium balance. In pathological conditions of sodium retention, impairment of the inhibitory renorenal reflexes contributes to an inappropriately increased efferent renal sympathetic nerve activity in the presence of sodium retention. In states of renal disease or injury, there is a shift from inhibitory to excitatory reflexes originating in the kidney. Studies in essential hypertensive patients have shown that renal denervation results in long-term reduction in arterial pressure, suggesting an important role for the efferent and afferent renal nerves in hypertension.

Download or read book Autonomic Neurology written by Eduardo E. Benarroch and published by Oxford University Press. This book was released on 2014-04-03 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to present a focused approach to the pathophysiology, diagnosis, and management of the most common autonomic disorders that may present to the clinical neurologist. Autonomic Neurology is divided into 3 sections. The first section includes 5 chapters reviewing the anatomical and biochemical mechanisms of central and peripheral nervous system control of autonomic function, principles of autonomic pharmacology, and a clinical and laboratory approach to the diagnosis of autonomic disorders. The second section focuses on the pathophysiology and management of orthostatic hypotension, postural tachycardia, baroreflex failure; syncope, disorders of sweating, neurogenic bladder and sexual dysfunction, gastrointestinal dysmotility, and autonomic hyperactivity. The final section is devoted to specific autonomic disorders, including central neurodegenerative disorders; common peripheral neuropathies with prominent autonomic failure; painful small fiber neuropathies; autoimmune autonomic ganglionopathies and neuropathies; focal brain disorders; focal spinal cord disorders; and chronic pain disorders with autonomic manifestations. This book is the product of the extensive experience of its contributors in the evaluation and management of the many patients with autonomic symptoms who are referred for neurologic consultation at Mayo Clinic in Rochester, Minnesota. Autonomic Neurology focuses on clinical scenarios and presentation of clinical cases and includes several figures showing the results of normal and abnormal autonomic testing in typical conditions. Its abundance of tables summarizing the differential diagnosis, testing, and management of autonomic disorders also help set this book apart from other books focused on the autonomic nervous system.

Book excerpt: 113 This system of monitoring might be improved further if all cases in this category were investigated jointly by a forensic pathologist and an anaesthesiologist at the very outset of the investigation and during the actual autopsy. Free Papers The Influence of Pancuronium on Primary Conjugated Bile Acids A. Fassoulaki, T. Mihas, A. Mihas and P. Kaniaris Experimental studies have been reported in which a prolonged action of steroid neuro­ muscular blocking agents followed bile acids administration(1, 2). A prolonged neuro­ muscular action of pancuronium has also been detected in patients with biliary obstruc­ tion(3). In the present study serum bile acids and intracellular liver enzymes were estimated after anaesthesia in which pancuronium was used as a muscle relaxant (Fig. 1). An at­ tempt is made to investigate the effect of pancuronium on bile acid levels. Material and Methods Twelve female patients aged between 40 and 50 years were studied. All of them were visited in the ward the night before the operation by the anaesthesiologist where their clinical condition was assessed and their consent was obtained to participate in the pre­ sent study. None of them had a history of hepatic disease or was taking drugs. The oper­ ation performed in all cases was modified radical mastectomy and intracellular liver en­ zymes are routinely determined in these patients preoperatively. The twelve patients were reassured and stated that they did not want to have any tranquillizer for premedi­ cation.

Download or read book Vasovagal Syncope written by Paolo Alboni and published by Springer. This book was released on 2014-11-20 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is exceptional in being devoted solely to vasovagal syncope (VVS), the most frequent cause of transient loss of consciousness in the general population. All aspects of VVS are covered, including epidemiology, pathophysiology, diagnosis and differential diagnosis, prognosis, therapy and implications for particular activities such as work, driving and physical activity. The context for the book is that about half of the population suffer from this type of loss of consciousness during their lifetime and then often call for general practitioner and/or emergency room assistance. While many pathophysiological aspects of VVS have been clarified, others remain elusive. The diagnosis of VVS may be easy, but it is sometimes challenging. From the therapeutic standpoint, few evidence-based therapies have been established and the large majority of treatments remain unsatisfactory. Vasovagal Syncope presents the latest evidence on all these issues and will be of value for internists, cardiologists, neurologists, emergency physicians and general practitioners.
