Serum KL-6 and surfactant protein D in children with 2009 pandemic H1N1 influenza infection.
A global pandemic influenza A (H1N1) outbreak occurred in 2009. Rapid progress of respiratory distress is one of the characteristic features of pandemic influenza A (H1N1) infection. The physiologic mechanism causing hypoxia in pandemic influenza A (H1N1) infection, however, has not been elucidated. ⋯ KL-6 and SP-D elevation were not significant in pandemic influenza A (H1N1) infection associated with chest radiographic abnormality. In pandemic influenza A (H1N1) infection, alveolar involvement was estimated to be little, and severe respiratory distress was probably caused by obstruction of peripheral bronchi.

To develop culturally appropriate and effective strategies to reduce the risk from pandemic influenza (H1N109) in rural and remote Australian Aboriginal and Torres Strait Islander communities. ⋯ The essential work of reducing risk of pandemic influenza with Aboriginal and Torres Strait Islander communities is not straightforward, but this project has highlighted a number of useful pathways to continue to journey along with communities. A number of strategies to reduce the spread of pandemic influenza in Aboriginal and Torres Strait Islander communities were identified. These strategies would make a good starting point for conversations with communities and health services. In Aboriginal and Torres Strait Islander communities the environment, community structures and traditions vary. Respectful engagement with communities is needed to develop effective policy.

The feasibility of age-specific travel restrictions during influenza pandemics.
Epidemiological studies have shown that imposing travel restrictions to prevent or delay an influenza pandemic may not be feasible. To delay an epidemic substantially, an extremely high proportion of trips (~99%) would have to be restricted in a homogeneously mixing population. Influenza is, however, strongly influenced by age-dependent transmission dynamics, and the effectiveness of age-specific travel restrictions, such as the selective restriction of travel by children, has yet to be examined. ⋯ Selectively restricting children from traveling overseas during a pandemic may potentially delay its arrival for a few weeks, depending on the characteristics of the pandemic strain, but could have less of an impact on the economy compared to restricting adult travelers. However, as long as adults have at least a moderate potential to trigger an epidemic, selectively restricting the higher risk group (children) may not be a practical option to delay the arrival of an epidemic substantially.

Low adherence to influenza vaccination campaigns: is the H1N1 virus pandemic to be blamed?
Over the last few months, debates about the handling of the influenza virus A (H1N1) pandemic took place, in particular regarding the change of the WHO pandemic definition, economic interests, the dramatic communication style of mass media. The activation of plans to reduce the virus diffusion resulted in an important investment of resources. Were those investments proportionate to the risk? Was the pandemic overrated? The workload of the Pediatric Emergency Room (P.E.R.) at a teaching hospital in Varese (Northern Italy) was investigated in order to evaluate the local diffusion and severity of the new H1N1 influenza epidemic. ⋯ The communication strategy adopted by the mass media was an important element during the pandemic: the absence of clarity contributed to the spread of a pandemic phobia that appeared to result more from the sensationalism of the campaign than from infection with the novel influenza A variant of human, avian, swine origin virus. One relevant effect of the media coverage was the extremely low adherence rate to the vaccination campaign for the 2009-2010 and 2010-2011, especially among the high-risk population and health care workers. One positive consequence was, however, the spread of preventive hygiene measures, such as hand washing.

Pandemic H1N1 influenza-associated hospitalizations in children in Madrid, Spain.
To describe the epidemiological and clinical characteristics of children hospitalized with 2009 pandemic influenza (pH1N1) in Madrid, Spain. ⋯ Children with underlying medical conditions experienced more severe pH1N1 disease. Risk factors for admission to the PICU included underlying neurological conditions, immunosuppression and abnormal initial chest X-ray.
