  • The infection was characterized by respiratory symptoms, fever, rapid progression, and significant hypoxemia.[ncbi.nlm.nih.gov]
Limited Mobility
  • In contrast, the viruses in cyto-D-treated cells show much more limited mobility ( Fig. 3 a ). These results suggest that stage I movement is an actin-dependent active transport.[doi.org]

Muscle Weakness
  • All six cases suffered from myalgia or muscle weakness especially in the lower extremities and the serum creatine kinase (CK) values were elevated above 1,000 IU/l without MB isoenzymes or electrocardiogram abnormalities.[ncbi.nlm.nih.gov]
  • To investigate the etiologic agent involved in myelopathy post influenza-like syndrome.[ncbi.nlm.nih.gov]

Brain Edema
  • The mild hypothermia suppressed the brain edema on computed tomography (CT) scanning and protected the brain from the subsequent irreversible neural cell damage.[ncbi.nlm.nih.gov]
  • Together with the rapid production of several inflammatory cytokines, the breakdown of the blood-brain barrier may induce severe brain edema and can be a major pathologic change for the disease.[ncbi.nlm.nih.gov]
Diffuse Encephalopathy
  • Focal reversible encephalopathy has rarely been reported in association with influenza virus infection, although it often provokes diffuse encephalopathies, with a poor prognosis.[ncbi.nlm.nih.gov]


  • The use of hemodynamic support by extracorporeal membrane oxygenation emerges as a promising treatment.[ncbi.nlm.nih.gov]
  • Oseltamivir is considered the drug of choice for patients with pandemic influenza for whom drug treatment is recommended because adamantanes seem to be ineffective against pandemic A/H1N1 influenza virus and zanamivir is contraindicated in people with[ncbi.nlm.nih.gov]
  • The child had the 275Y mutation detected after being persistently A/H1N1 09 RT-PCR positive while receiving oseltamivir treatment. Resistance was not detected in 17 pre-treatment samples and 54 A/H1N1 09 RT-PCR positive outpatients.[ncbi.nlm.nih.gov]
  • Abstract We report, to our knowledge, the first successful treatment of novel Influenza A (H1N1)/2009 chronic pericardial effusion in an adult.[ncbi.nlm.nih.gov]
  • Early admission, prompt diagnosis and early recourse to antiviral treatment gives better results in H1N1 infected pregnant women (Fig. 2, Ref. 10).[ncbi.nlm.nih.gov]
