Non-contrast MR dacryocystography for the evaluation of epiphora and recurrent dacryocystitis: A preliminary study.

Introduction: Obstruction of the lacrimal drainage represents a common ophthalmologic issue. The blockage may interest any level of the lacrimal drainage pathway, and it is important to find the site of obstruction to plan the most appropriate treatment. In this study, findings from magnetic resonance (MR) dacryocystography were compared with findings from endoscopic and surgical procedures to evaluate the accuracy of MR dacryocystography in localizing the site of nasolacrimal duct obstruction.

Can Volumetric and Morphological Variants of Sphenoid Sinuses Influence Sinuses Opacification?

Improvements in computed tomography and in functional endoscopic sinus surgery have recently increased interest toward paranasal sinus anatomy and anatomic variations that can be observed in patients affected by sinusitis. Isolated sphenoid sinusitis is a relatively rare pathology, often related to nonspecific symptoms, therefore making diagnosis difficult. The correlation between this type of sinusitis and anatomical variants remains unclear.

Endoscopic laryngeal patterns in vagus nerve stimulation therapy for drug-resistant epilepsy.

In 30% of patients with epilepsy seizure control cannot be achieved with medications. When medical therapy is not effective, and epilepsy surgery cannot be performed, vagus nerve stimulator (VNS) implantation is a therapeutic option. Laryngeal patterns in vagus nerve stimulation have not been extensively studied yet.

Open-label, randomized, placebo-controlled evaluation of intracoronary adenosine or nitroprusside after thrombus aspiration during primary percutaneous coronary intervention for the prevention of microvascular obstruction in acute myocardial infarction: the REOPEN-AMI study (Intracoronary Nitroprusside Versus Adenosine in Acute Myocardial Infarction).

Objectives: This study sought to assess whether intracoronary adenosine or nitroprusside following thrombus aspiration (TA) is superior to TA alone for the prevention of microvascular obstruction (MVO) in ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI).

Background: MVO, due to its multifactorial pathogenesis, still occurs after TA in a sizeable portion of patients.

Methods: We performed a placebo-controlled, randomized, open-label, blind-examination, multicenter trial.

Randomized evaluation of intracoronary nitroprusside vs. adenosine after thrombus aspiration during primary percutaneous coronary intervention for the prevention of no-reflow in acute myocardial infarction: the REOPEN-AMI study protocol.

Background: Thrombus aspiration improves microvascular obstruction in patients with acute myocardial infarction treated by percutaneous coronary intervention. However, drugs such as nitroprusside and adenosine have not yet been tested as adjuncts to thrombus aspiration. Therefore, we designed a placebo-controlled, randomized, open-label, blind-examination, multicenter trial assessing the effects of intracoronary nitroprusside or adenosine on microvascular obstruction in patients undergoing primary or rescue percutaneous coronary intervention and thrombus aspiration.
