Randomized Controlled Trial Multicenter StudyRandomized, multicenter trial of a single dose of AS03-adjuvanted or unadjuvanted H1N1 2009 pandemic influenza vaccine in children 6 months to <9 years of age: safety and immunogenicity.
During the 2009-2010 influenza pandemic, we evaluated the immunogenicity and safety of different H1N1 2009 pandemic influenza vaccines delivering various viral hemagglutinin (HA) doses with or without AS03 (a tocopherol oil-in-water emulsion-based adjuvant system) in children (NCT00976820). ⋯ AS03-adjuvanted H1N1 2009 pandemic influenza vaccine (3.75 µg or 1.9 µg HA), administered as 2 doses, was highly immunogenic, induced long-term immune response to 6 months, with a clinically acceptable safety profile in children aged 6 months to <9 years of age.

Randomized Controlled Trial Multicenter StudyImmunogenicity and safety of two tetravalent (measles, mumps, rubella, varicella) vaccines coadministered with hepatitis a and pneumococcal conjugate vaccines to children twelve to fourteen months of age.
This study compared single-dose tetravalent measles, mumps, rubella, varicella vaccine, Priorix-Tetra, stored refrigerated (GSK+4C) or frozen (GSK-20C), with ProQuad (Merck-20C), when coadministered with hepatitis A vaccine (HAV) and 7-valent pneumococcal conjugate vaccine (PCV7). ⋯ Noninferiority of both GSK measles, mumps, rubella, varicella vaccines versus Merck-20C was demonstrated for responses to measles, mumps and rubella viruses but was not fully demonstrated for varicella-zoster virus. The vaccines showed acceptable reactogenicity/safety when coadministered with HAV and PCV7.

Frequency and trajectory of abnormalities in respiratory rate, temperature and oxygen saturation in severe pneumonia in children.
The frequency or trajectory of vital sign abnormalities in children with pneumonia has not been described. In a cohort of 2714 patients with severe pneumonia identified and treated as per the World Health Organization definition and recommendations, tachypnea, fever and hypoxia were found in 68.9%, 23.6% and 15.5% of children, respectively. Median oxygen saturation returned to a normal range by 10 hours following initiation of treatment, followed by temperature at 12 hours and respiratory rate at 22 hours for subjects <12 months and at 48 hours for those ≥ 12 months of age.

Case ReportsLeukoreduction in patients with severe pertussis with hyperleukocytosis.
When pertussis is associated with hyperleukocytosis, mortality approaches to 80%. Immature leukocytes have been identified in pulmonary arterioles, small arteries and venules. Techniques aimed at reducing leukocyte mass might improve the prognosis of these patients. We report our experience with 3 patients in whom a leukoreduction was performed in the context of severe pertussis and hyperleukocytosis.
