INTRODUCTION Experimental research has demonstrated that the level of neuroprotection conferred by the various barbiturates is not equal. Until now no controlled studies have been conducted to compare their effectiveness, even though the Brain Trauma Foundation Guidelines recommend that such studies be undertaken. The objectives of the present study were to assess the effectiveness of pentobarb...

BACKGROUND AND PURPOSE In medically refractory idiopathic intracranial hypertension, optic nerve sheath fenestration or CSF shunting is considered the next line of management. Venous sinus stenosis has been increasingly recognized as a treatable cause of elevated intracranial pressure in a subset of patients. In this article, we present the results of the largest meta-analysis of optic nerve sh...

Atherosclerotic renal artery stenosis (RAS) is relatively common and often associated with reversible hypertension, progressive renal insufficiency, and/or coronary-independent pulmonary edema. Not all RAS is associated with renovascular hypertension. Historical and physical findings may suggest renovascular hypertension and warrant investigation for RAS. Noninvasive diagnostic imaging options ...

The creation of transjugular intrahepatic portosystemic shunt (TIPS) is a widely performed technique to relieve portal hypertension, and to manage recurrent variceal bleeding and refractory ascites in patients where medical and/or endoscopic treatments have failed. However, portosystemic shunt creation can be challenging in the presence of chronic portal vein occlusion. In this case report, we ...

The patient investigated was a 43-year-old woman with primary pulmonary hypertension (PPH) and refractory protein-losing enteropathy (PLE). She underwent living-donor lobar lung transplantation (LDLLT), which led to remarkable improvement in both pulmonary hypertension and PLE. Although there have been no reports, to our knowledge, that have demonstrated PLE as a complication of PPH, the presen...

Surgical and interventional therapies for pulmonary arterial hypertension (PAH) in appropriately selected patients have the potential to dramatically improve or, in some cases, cure PAH. These include atrial septostomy, a palliative procedure or bridge to transplantation in patients with refractory right heart failure, pulmonary thromboendarterectomy for pulmonary hypertension associated with c...

Renovascular hypertension is a potentially curable form of high blood pressure that is thought to be extremely rare among blacks. We demonstrate, however, that in a clinically selected population, the prevalence of renovascular hypertension is similar in blacks and whites. We prospectively evaluated 167 hypertensive subjects who had one or more clinical features known to be associated with reno...

A 52-year-old Caucasian woman with essential resistant and refractory hypertension despite optimal medical therapy, including 6 different antihypertensive drugs was referred for the catheter-based renal denervation. Due to unfavourable anatomy because of non-critical fibromuscular dysplasia on the right renal artery, renal denervation of only the left renal artery was performed. Before and afte...

Electrical stimulation of baroreceptor afferents was used in the 1960's in several species, including human beings, for the treatment of refractory hypertension. This approach bypasses the site of baroreceptor mechanosensory transduction. Chronic electrical stimulation of arterial baroreceptors, particularly of the carotid sinus nerve (Hering's nerve), was proposed as an ultimate effort to trea...

We have shown previously that inhibition of small conductance Ca(2+)-activated K(+) (SK) channels is antiarrhythmic in models of acutely induced atrial fibrillation (AF). These models, however, do not take into account that AF derives from a wide range of predisposing factors, the most prevalent being hypertension. In this study we assessed the effects of two different SK channel inhibitors, NS...
