[LSD score. A new classification system for peristomal skin lesions].

Background: Peristomal skin lesions are frequent complications of ostomy; however, there is no generally accepted nomenclature and classification system.

Objective: An interdisciplinary German expert panel (GESS) composed of ten members, developed an innovative semiquantitative classification system for peristomal skin lesions for further stratification of ostomy therapy. This score is based on criteria which can be assessed by stomal therapists and treating physicians.

Impact of prophylactic therapy for postoperative thromboembolism on prospective payment.

Widescale implementation of prospective payment systems as a means of reimbursing hospitals on the basis of diagnosis-related group designation has important implications with respect to the selection of drug therapy. Instead of analyzing costs on a departmental basis, pharmacists need to identify the impact of optimal drug therapy on overall profitability. Clinically evident deep venous thrombosis and pulmonary embolism occur in approximately 3.

Intravenous glyceryl trinitrate (nitroglycerin). A review of its pharmacological properties and therapeutic efficacy.

The recently introduced preparation of intravenous glyceryl trinitrate (nitroglycerin) provides a rapid steady therapeutic blood concentration of nitrates during continuous infusion. Intravenous glyceryl trinitrate causes venodilation at low doses, but at higher doses dilates both arteries and veins. Its principal haemodynamic effects at therapeutic dosages include a decrease in blood pressure in preload (left ventricular filling pressure) and in determinants of afterload, and a decrease in myocardial oxygen demand.
