Aguideline tells you how to get someplace, whereas a lighthouse keeps you off the rocks; both can shepherd you on a safe journey toward your goal. The American College of Cardiology (ACC), in concert with the American Heart Association (AHA), has been at the forefront of developing guidelines for percutaneous coronary interventions (PCI).1 In an era in which there are multiple data sets to draw...
Pacemaker implantation is an established therapy for patients with sinus node disease or atrioventricular block. However, we sometimes encounter cases in which delivery of the leads is technically difficult. The buddy wire technique is known to be useful in delivering stents when difficulties are encountered due to vessel tortuosity or calcification during percutaneous coronary intervention. In...
Skin drug delivery can be subdivided into topical and transdermal administration. Transdermal administration can take advantage of chemical and physical strategies that can improve skin permeability and allow drug penetration. In this study, the development of a skin penetration profile was carried out by an in vitro technique for a microencapsulated system of ibuprofen. Release experiments wer...
By any measure, transdermal drug delivery (TDD) is a successful controlled release technology. Over the last 30+ years, a steady flux of transdermal products have received regulatory approval and reached the market. For the right compounds, TDD is an effective and preferred route of administration; for others, delivery across the skin makes no sense at all. Currently, the "rules" that govern (p...
The article presents our experience of observing two different approaches for endoscopic retrograde drainage in patients with malignant pathology the pancreatobiliary zone, complicated by bile duct obstruction. In one case, case dysfunction installed uncovered stent as a result incrustation salts and/or tumor invasion, stent-to-stent restenting was performed. second if it impossible to pass gui...
We have assessed the release of amethocaine from a new patch delivery system and subsequent drug diffusion through human stratum corneum and whole skin. We found that the patch system was more efficient than an amethocaine gel preparation. It was also observed, both in vitro and in vivo, that the stratum corneum acted as a reservoir for amethocaine. A double-blinded clinical trial, using 30- an...
