[Effect on duration of antibiotic therapy and drug cost by introducing critical pathway for patients with CAP in Japan].

The aim of this study was to assess whether Marrie's critical pathway is an effective approach to reduce the duration of antibiotic intravenous therapy and drug cost in patients with community-acquired pneumonia (CAP) in Japan. We conducted a retrospective cohort study in patients with CAP who were admitted to a community hospital or a university hospital. We collected clinical and economic data from medical records and medical fee receipts and estimated drug cost for switching the dosage form using Marrie's critical pathway.

Follow-up survey of a large-scale multicenter, double-blind study of triple therapy with lansoprazole, amoxicillin, and clarithromycin for eradication of Helicobacter pylori in Japanese peptic ulcer patients.

Background: To evaluate histopathological changes and effects on inhibition of ulcer recurrence, a follow-up survey was performed in Japanese patients with Helicobacter pylori-positive active peptic ulcers. These patients had previously participated in a large-scale multicenter trial of triple therapy with lansoprazole (LPZ)/amoxicillin (AMPC)/clarithromycin (CAM) for eradication of H. pylori.
