Intracerebroventricular anaerobic dopamine in Parkinson's disease with L-dopa-related complications: a phase 1/2 randomized-controlled trial.

Continuous compensation for cerebral dopamine deficiency represents an ideal treatment for Parkinson's disease. Dopamine does not cross the digestive and blood-brain barriers and is rapidly oxidized. The new concept is the intracerebroventricular administration of anaerobic dopamine (A-dopamine) using an abdominal pump connected to a subcutaneous catheter implanted in the third ventricle, near the striatum.

Optimising insulin aspart practices in a neonatal intensive care unit: a clinical and pharmaco-technical study.

Neonatal hyperglycaemia is frequent and requires insulin therapy. To resolve the difficulties encountered by paediatricians in stabilising glycaemia, the preparation and administration of insulin aspart were assessed and optimised. After high-performance liquid chromatography (HPLC-UV) assessment of insulin aspart preparations made according to the old protocol, a new protocol was drawn up.

Doppler Ultrasound Monitoring of Echogenicity in Asymptomatic Subcritical Carotid Stenosis and Assessment of Response to Oral Supplementation of Vitamin K2 (PLAK2 Randomized Controlled Trial).

Background: Plaque composition may predict the evolution of carotid artery stenosis rather than its sole extent. The grey scale median (GSM) value is a reproducible and standardized value to report plaque echogenicity as an indirect measure of its composition. We monitored plaque composition in asymptomatic subcritical carotid stenosis and evaluated the effect of an oral modulating calcification factor (vitamin K2).

Late Open Conversion Following Failure of EVAR and TEVAR: "State of the Art".

Abdominal endovascular aneurysm repair (EVAR) and thoracic endovascular aneurysm repair (TEVAR) have changed the aortic surgery, due to several advantages in terms of reduced morbidity and mortality. However, increasing rate of late complications requiring secondary procedures has been observed over time. Even if the majority of them may be treated by means of endovascular techniques, late open surgical conversion (LOSC) is required in specific situations.

A Modified Proximal Stent-Graft for Spinal Cord Preconditioning During Staged Endovascular Repair of Thoracoabdominal Aortic Aneurysms.

To describe a new custom-made thoracic device able to seal against the aortic wall and occlude intercostal arteries for spinal cord preconditioning during the first thoracic stage of a thoracoabdominal endovascular repair. The custom-made device, based on the Zenith Alpha stent-graft, combines different features from 2 previously described devices: the outer part is designed with a bell-bottom configuration similar to the "Embo" stent-graft, while the inner part mimics the "2 in 1" design. The outer stent-graft is designed to span the entire length of the thoracic aorta and cover as many intercostal arteries as possible during the first stage to effectively precondition the spinal cord.

Staged Fenestrated/Branched Repair of Postdissecting Thoracoabdominal Aneurysm With Candy-Plug False Lumen Occlusion for Spinal Cord Preconditioning.

To describe a possible application of thoracic false lumen occlusion techniques with a Candy-Plug occluder to induce false lumen thrombosis for preconditioning the spinal cord during staged fenestrated repair of postdissecting thoracoabdominal aneurysms. A Candy-Plug occluder is deployed within the thoracic false lumen after proximal entry tear coverage with a standard thoracic stent-graft during staged repair of postdissecting thoracoabdominal aneurysms. The blockade of thoracic false lumen retrograde reperfusion from distal entry tears induces a controlled thrombosis of both the thoracic false lumen and intercostal arteries.
