Enzephalopathie nach Intoxikation mit einem Anticholinergikum

2008

A 55-year-old chemical laboratory technician developed mydriasis and ocular hypertension, which lasted for 6 weeks, after synthesizing several kilograms of a scopolamine-related test agent with anticholinergic action and then decanting a powdery intermediary substance, the dust of which he may have inhaled. Six weeks later he suddenly had symptoms of an acute intoxication while synthesizing a scopolamine-related substance. The anticholinergic delirium regressed completely within one day requiring no treatment. But subsequently he developed symptoms of a toxic encephalopathy. This only partially regressed over the following 3 years. Its probable cause is thought to have been either the manif…

Changes of plasma endothelin and growth factor levels, and of left ventricular mass, after chronic AT1-receptor blockade in human hypertension.

1998

The stimulation of autocrine and paracrine factors such as basic fibroblast- (bFGF) and platelet-derived (PDGF) growth factors mediates many of the growth-promoting actions of angiotensin II. The aim of this study was to evaluate the effect of chronic AT1-receptor blockade on plasma endothelin-1 (ET-1) and growth factors levels, and on left ventricular mass, in essential hypertension (EH). The study population consisted of 16 patients with mild-moderate EH, and 25 normotensive controls. In the EH patients under basal conditions, and after 3 and 6 months of chronic therapy with Losartan 50 mg/day, we measured serum levels of ET-1, bFGF and PDGF, and tumor necrosis factor (TNF). At the same t…

Does the renin-angiotensin system also regulate intra-ocular pressure?

2009

The renin-angiotensin-aldosterone system is known to play an essential role in controlling sodium balance and body fluid volumes, and thus blood pressure. In addition to the circulating system which regulates urgent cardiovascular responses, a tissue-localized renin-angiotensin system (RAS) regulates long-term changes in various organs. Many recognized RAS components have also been identified in the human eye. The highly vasoconstrictive angiotensin II (Ang II) is considered the key peptide in the circulatory RAS. However, the ultimate effect of RAS activation at tissue level is more complex, being based not only on the biological activity of Ang II but also on the activities of other produ…

Cardiorenal syndrome type 4: From chronic kidney disease to cardiovascular impairment

2016

Cardiorenal syndrome type 4 (CRS type 4), or chronic renocardiac syndrome, has been defined as "chronic abnormalities in renal function leading to cardiac disease" and recognizes the extreme burden of cardiovascular disease (CVD) risk in patients with chronic kidney disease (CKD). CKD is common and increasingly recognized as a risk factor for CVD. Even though the treatment for CVD has dramatically improved over the past decades, it still takes responsibility for up to 50% of deaths in CKD patients. For this reason, patients with CKD should be thoroughly evaluated for cardiovascular risk factors that require careful management, given the significant burden of CRS type 4 on the healthcare sys…

An update on hypertensive emergencies and urgencies

2015

Severe acute arterial hypertension is usually defined as 'hypertensive crisis', although 'hypertensive emergencies' or 'hypertensive urgencies', as suggested by the Joint National Committee and the European Society of Hypertension, have completely different diagnostic and therapeutic approaches. The prevalence and demographics of hypertensive emergencies and urgencies have changed over the last four decades, but hypertensive emergencies and urgencies are still associated with significant morbidity and mortality. Different scientific societies have repeatedly produced up-to-date guidelines; however, the treatment of hypertensive emergencies and urgencies is still inappropriate, with potentia…

Management of high blood pressure in children and adolescents: recommendations of the European Society of Hypertension.

2009

Hypertension in children and adolescents has been gaining ground in cardiovascular medicine, mainly due to the advances made in several areas of pathophysiological and clinical research. These guidelines arose from the consensus reached by specialists in the detection and control of hypertension in children and adolescents. Furthermore, these guidelines are a compendium of scientific data and the extensive clinical experience it contains represents the most complete information that doctors, nurses and families should take into account when making decisions. These guidelines, which stress the importance of hypertension in children and adolescents, and its contribution to the current epidemi…

Reproducibility and validity of ambulatory blood pressure monitoring in children.

2002

During the past several years ambulatory blood pressure monitoring (ABPM) has been introduced into the study of hypertension and has become a useful tool in making clinical decisions. The ABPM improves the reproducibility of the estimates of a subject's casual blood pressure (BP) both in normotensive and in hypertensive subjects, independent of age. The advantages of ambulatory BP (ABP) over its office counterpart have been studied in children to observe the relationship between BP measurement and early markers of organ damage. In different groups of subjects that have included normotensives, essential hypertensives, renal transplant recipients, or patients with repair of an aortic coarctat…
