Background: Tokyo Guidelines for the management of acute cholangitis and cholecystitis

There are no evidence-based-criteria for the diagnosis, severity assessment, of treatment of acute cholecysitis or acute cholangitis. For example, the full complement of symptoms and signs described as Charcot’s triad and as Reynolds’ pentad are infrequent and as such do not really assist the clinician with planning management strategies. In view of these factors, we launched a project to prepare evidence-based guidelines for the management of acute cholangitis and cholecystitis that will be useful in the clinical setting. This research has been funded by the Japanese Ministry of Health, Labour, and Welfare, in cooperation with the Japanese Society for Abdominal Emergency Medicine, the Japan Biliary Association, and the Japanese Society of Hepato-Biliary-Pancreatic Surgery. A working group, consisting of 46 experts in gastroenterology, surgery, internal medicine, emergency medicine, intensive care, and clinical epidemiology, analyzed and examined the literature on patients with cholangitis and cholecystitis in order to produce evidence-based guidelines. During the investigations we found that there was a lack of high-level evidence, for treatments, and the working group formulated the guidelines by obtaining consensus, based on evidence categorized by level, according to the Oxford Centre for Evidence-Based Medicine Levels of Evidence of May 2001 (version 1). This work required more than 20 meetings to obtain a consensus on each item from the working group. Then four forums were held to permit examination of the Guideline details in Japan, both by an external assessment committee and by the working group participants (version 2). As we knew that the diagnosis and management of acute biliary infection may differ from country to country, we appointed a publication committee and held 12 meetings to prepare draft Guidelines in English (version 3). We then had several discussions on these draft guidelines with leading experts in the field throughout the world, via e-mail, leading to version 4. Finally, an International Consensus Meeting took place in Tokyo, on 1–2 April, 2006, to obtain international agreement on diagnostic criteria, severity assessment, and management

Management of extensive subfoveal haemorrhage secondary to neovascular age-related macular degeneration

Background: To evaluate the clinical outcomes of subfoveal haemorrhages secondary to neovascular age-related macular degeneration (AMD), which were treated with intravitreal recombinant tissue plasminogen activator (rTPA)/gas and anti-vascular endothelial growth factor (anti-VEGF) drug or with an intravitreal anti-VEGF monotherapy. Methods: This is a retrospective pilot study. Patients who received intravitreal rTPA/gas and anti-VEGF injections (n=20, bevacizumab or ranibizumab) were included in group A. Patients who refused prone positioning after rTPA/gas injections and were treated with an anti-VEGF monotherapy (bevacizumab) alone were included into group B (n=10). Changes in baseline visual acuity (VA, Snellen), central retinal thickness (CRT) and haemorrhage size were analysed. Results: Mean baseline VA was 0.15plusminus0.2 and 0.25plusminus0.17 in groups A and B, respectively. At month 4, significant improvement in mean VA was observed in group A (mean difference: +0.1plusminus0.14; P=0.003), and a stabilization in group B (mean difference: +0.008plusminus0.2; P=0.94). CRT decreased significantly by 70 mum in group A (P=0.001) and by 84 mum in group B (P=0.03). The mean size of subfoveal haemorrhage in groups A and B was 20.2 mm2 and 19.1 mm2 at baseline and 0.0 mm2 and 2.0 mm2 at month 4, respectively. The anti-VEGF treatmentrate was 1.6 in group A and 3.0 in group B. Conclusion: In patients with extensive subfoveal haemorrhage secondary to neovascular AMD, the combination therapy of rTPA/pneumatic displacement and anti-VEGF results in mean improvement of VA and stabilization of morphological parameters. If rTPA and pneumatic displacement combination is contraindicated, an anti-VEGF monotherapy may be performed to prevent further visual loss
