Hypothalamic abnormalities and Parkinsonism associated with H1N1 influenza infection.
Summary of "Hypothalamic abnormalities and Parkinsonism associated with H1N1 influenza infection."
To describe a case of a young adult with severe H1N1 influenza illness associated with hypothalamic abnormalities and post-influenza parkinsonism.
Case report. Patient: A 22-year-old woman with H1N1 influenza infection developed encephalopathy followed by diverse hypothalamic dysfunction manifestations, sleeplessness, and persistent parkinsonian features.
CSF analysis, brain imaging and EEG ruled out hypoxic brain injury or other illnesses.
A number of viruses have been associated with both acute and chronic parkinsonism. A link between parkinsonism and influenza viruses is somewhat controversial. This is the first reported case of parkinsonism following an H1N1 influenza infection.

Medical and Biotech [MESH] Definitions
Influenza A Virus, H1n1 Subtype
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 1 and neuraminidase 1. The H1N1 subtype was responsible for the Spanish flu pandemic of 1918.
Influenza In Birds
Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.
Influenza B Virus
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
Hemagglutinin Glycoproteins, Influenza Virus
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
Vaccines used to prevent infection by viruses in the family ORTHOMYXOVIRIDAE. It includes both killed or attenuated vaccines. The composition of the vaccines is changed each year in response to antigenic shifts and changes in prevalence of influenza virus strains. The vaccine is usually bivalent or trivalent, containing one or two INFLUENZAVIRUS A strains and one INFLUENZAVIRUS B strain.
PURPOSE: Given the recent paper by Jang et al. on "A Highly Pathogenic H5N1 Influenza Virus" which reported a novel animal model of parkinsonism, we aimed to perform a complete historical review of th...
The cardiac effects imposed by the novel H1N1 influenza strain have not been elucidated until now. Electrocardiographic (ECG) abnormalities were evaluated in a series of 50 patients with confirmed nov...
Purpose of study The demographics, clinical features and outcome of patients with pandemic influenza A (H1N1) 2009 infection were compared with a concurrent cohort of patients with seasonal influenza...
Acute kidney injury (AKI) is rarely reported in the clinical course of H1N1 infection and this condition is strongly related with increasing of mortality risk. However, there are no sufficient data ab...
BACKGROUND: While viral myocarditis and heart failure are recognized and feared complications of seasonal influenza A infection, only limited information is available for 2009 influenza A(H1N1)-induce...
This is a phase III, randomized, controlled, open label study with two vaccine regimens. The study will assess the relative safety and immunogenicity of vaccine regimens comparing adjuvant...
A total of 51 children between the ages of 4 and 9 will be randomized to receive a two dose schedule of either licensed live attenuated A/California/07/09 influenza vaccine (LAIV) or licen...
The patients of pediatric haemato-oncology have a higher risk for novel H1N1 influenza infection than general population, and they are strongly recommended to receive novel H1N1 vaccinatio...
Both pregnant women and people infected with HIV are at increased risk of viral infection, including influenza infection. Pregnant women infected with HIV may be at particular risk of infe...
The demographic characteristics, clinical features, course, and outcomes of severe H1N1 influenza infection requiring intensive care have not been defined rigorously and systematically. Wh...
