Idiopathic normal pressure hydrocephalus (iNPH) is characterized by gait disturbance, dementia and /or urinary incontinence, dilation of the ventricular system and normal opening cerebrospinal fluid pressure. Shunt surgery is the standard treatment of iNHP. Diversions with programmable valves are recommended, once drainage pressure can be changed. However, well-defined protocols still ...

A subset of hydrocephalic patients in whom shunts are placed at an early age will develop craniocerebral disproportion (CCD), an iatrogenic mismatch between the fixed intracranial volume and the growing brain. The lack of a reliable, reproducible method to diagnose this condition, however, has hampered attempts to treat it appropriately. ...

Carotid artery intima-media thickness (IMT) has emerged as a predictor of cardiovascular events. Home blood pressure (BP) is more closely associated with cardiovascular prognosis than clinic BP. The aim of this study was to compare the progression of carotid IMT with respect to strict and mild control of morning home ...

The importance of systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP), on the incidence of coronary heart disease (CHD) and stroke are known. However, the importance of blood pressure (BP)-age shifts regarding the stroke incidence is not clearly known. The BP changes with the advancement of ...

Resistant hypertension is highly prevalent, and is the form of arterial hypertension that is most difficult to treat. Many patients diagnosed with this disease do not have resistant hypertension, but rather have mismanaged primary hypertension. In many cases blood pressure can be controlled by directly addressing underlying causes such as ...

In the present historical review, we highlight several articles outlining contributions of the Framingham Heart Study over the span of nearly seven decades to our understanding of the epidemiology of blood pressure (BP), atrial fibrillation and genetic factors as they relate to cerebrovascular disease. In 1970, Framingham investigators led by ...

PURPOSE: Congenital portosystemic shunts (CPSS) with portal venous hypoplasia cause hyperammonemia. Acute shunt closure results in portal hypertension. A transcatheter method of staged shunt reduction to afford growth of portal vessels followed by shunt closure is reported. METHODS: Pressure measurements and angiography in the CPSS or superior mesenteric artery (SMA) ...

BACKGROUND: It is suggested that disturbed CSF dynamics are involved in the pathophysiology of idiopathic normal pressure hydrocephalus (INPH). The pulsatility curve describes the relationship between intracranial pressure (ICP) and the amplitude of cardiac related ICP pulsations. The position of baseline ICP on the curve provides information about the physiological ...

BACKGROUND: In treating idiopathic normal pressure hydrocephalus (INPH) with a shunt there is always a risk of underdrainage or overdrainage. The hypothesis is tested whether patients treated using an adjustable valve preset at the highest opening pressure leads to comparable good clinical results with less subdural effusions than in a ...

We present pressure-volume loops obtained from two patients with single-ventricle physiology, one with a modified Blalock-Taussig shunt and one with a right ventricle-to-pulmonary artery shunt. The dissimilarities in pressure-volume loop contour and related indices highlight potentially important differences in ventricular mechanics between the shunt types.

Background: MicroRNAs (miRNAs) are endogenous, non-coding, short, single-stranded RNAs and represent a new class of gene regulators. Recent evidence supports a role for miRNAs in cardiovascular pathophysiology and atherosclerosis development. We have previously demonstrated that miR-145 is widely expressed in human atherosclerotic lesions and its downregulation has been correlated with ...

OBJECTIVE:: Uncontrolled hypertension under antihypertensive multidrug regimen is not necessarily always true resistance. Incomplete adherence is one of several possible causes of uncontrolled hypertension. Nonadherence remains largely unrecognized and is falsely interpreted as treatment resistance, as it is difficult to confirm or exclude objectively. This is the first study assessing ...

Chemoreceptors play an important role in the autonomic modulation of circulatory and ventilatory responses to changes in arterial O2 and/or CO2. However, studies evaluating hemodynamic responses to hypoxia and hypercapnia in rats have shown inconsistent results. Our aim was to evaluate hemodynamic and respiratory responses to different levels of hypoxia ...

Apart from the well-known role of hypertension in cerebrovascular disease, chronic kidney disease is emerging as an independent risk factor for stroke. Although the mechanism underlying the relationship between blood pressure variability, diurnal blood pressure variation disruption (e.g. nondipping) and kidney dysfunction is not fully understood, these factors are closely ...

Blood pressure is a strong risk factor for ischemic and atherosclerotic events such as stroke. Blood pressure is often elevated in patients with chronic kidney disease. Consequently, chronic kidney disease patients are at high risk of developing cardiovascular and cerebrovascular damage. Blood pressure reduction by means of inhibiting the renin-angiotensin-aldosterone ...

Subependymomas are rare, slow-growing benign neoplasms. Although most are asymptomatic, they can present with symptoms related to increased intracranial pressure and hydrocephalus. We describe a 47-year-old man with worsening headaches who was found to have a subependymoma, with a focus on the imaging findings, differential diagnoses, pathology, and treatment.

Introduction. Increased pressure in portal venous system is relatively a rare complication after chemoradiotherapy for Wilms' tumor (WT). In paediatric population, feasibility and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in portal hypertension nonresponsive to medical or endoscopic treatment have been recently advocated. We report a case of TIPS positioning ...

Since 1965 many ventriculo-peritoneal shunt systems have been inserted worldwide to treat hydrocephalus. The most frequent indication in adults is normal pressure hydrocephalus (NPH), a condition that can be difficult to diagnose precisely. Surgical intervention with flow-regulated and differential pressure-regulated ventriculo-peritoneal shunts remains controversial. Knowledge about the benefits and harms ...

Aripiprazole is widely used in the treatment of schizophrenia and bipolar disorders. Although antipsychotics generally have hypotensive effects, two cases were identified that demonstrated hypertension during the switch from other antipsychotics to aripiprazole. The hypertensive state of these patients recovered after switching back to other antipsychotics, and these cases suggest ...
