First identified in humans in Hong Kong, influenza A/H5N1, known commonly as avian influenza, has caused human disease in 15 countries around the world. Although the current number of confirmed patients is tiny compared to seasonal and the recently emerged H1N1 'swine' influenza, H5N1 remains a candidate for the next highly pathogenic influenza pandemic. Currently, H5N1 has very limited ability to spread from person-to-person but this may change because of mutation or reassortment with other influenza viruses leading to an influenza pandemic with high mortality. If this occurs travellers are likely to be affected and travel medicine doctors will need to consider avian influenza in returning febrile travellers. The early clinical features may be dismissed easily as 'the flu' resulting in delayed treatment. Treatment options are limited. Oral oseltamivir alone has been the most commonly used drug but mortality remains substantial, up to 80% in Indonesia. Intravenous peramivir has been filed for registration and IV zanamivir is being developed. This review will focus on the epidemiological and clinical features of influenza A/H5N1 avian influenza and will highlight aspects relevant to travel medicine doctors. © 2009 Elsevier Ltd.

Context: Groove pancreatitis is a rare condition characterized by fibrotic inflammation affecting the groove anatomical area between the head of the pancreas, the duodenum and the common bile duct. Objectives: We report a miniseries of five cases treated surgically in our centre over a period of four years. A review of the literature is also discussed. Methods: Patients undergoing pancreaticoduodenectomy over a four-year period were retrospectively reviewed. Patients with a confirmed histological diagnosis of groove pancreatitis were assessed under the headings; patient demographics, presenting symptoms, radiological and histological findings. Results: One-hundred and 60 pancreaticoduodenectomies were performed. Thirty-nine cases demonstrated benign disease and within this, five cases (3.1% of total series; 12.8% of benign cases) were groove pancreatitis. All patients presented with abdominal pain and weight loss, and the majority consumed excess alcohol and were smokers. Radiological findings (CT/MRCP/EUS) revealed duodenal wall thickening in all cases, abnormalities at the head of pancreas and bile duct dilation in four, and cystic changes in the duodenal wall and pancreatic duct dilation in three cases. Groove fibrosis, Brunner's gland hyperplasia and cystic changes in duodenal wall were present in all cases on histological review. All patients reported significant improvement in quality of life at 12 months after surgery. Conclusion: Groove pancreatitis can present in a similar fashion to head of pancreas cancer and chronic pancreatitis. For this reason it is paramount for clinicians to be aware of groove pancreatitis, as this can lead to the correct diagnosis and management of this unique disease.
