1. 11. Respiratory tract infections, reflex apnea and sudden infant death : experimental and epidemiological studies with special reference to respiratory syncytial virus, Bordetella pertussis and sleep position

   Författare :Carl Lindgren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Bordetella pertussis; Infection; Interleukins; Laryngeal chemoreflex; Respiratory syncytial virus; Reflex apnea; Sleep; Sleeping position; Sudden infant death;

   Sammanfattning : The seasonal distribution of Sudden infant death syndrome (SIDS) followed the prevalence of respiratory tract infections (RTI) when prone sleeping position was recommended, but this covariation has recently been attenuated. Airway infections in the young infant are known to produce respiratory disturbances. LÄS MER

3. 12. Chlamydia pneumoniae in Children - Epidemiology and Clinical Implications

   Författare :Erik Normann; Björn Wettergren; Håkan Gnarpe; Claes Sundelin; Birger Trollfors; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; allergy; asthma; children; Chlamydia pneumoniae; immunohistochemistry; microimmunofluorescence; polymerase chain reaction; respiratory tract infection; Pediatrik; Paediatric medicine; Pediatrisk medicin;

   Sammanfattning : Chlamydia pneumoniae is a human respiratory tract pathogen. Seroepidemiological studies indicate that C. pneumoniae infection is most common in school-aged children and infrequently detected in younger children.The aims of this study were to further elucidate the prevalence of C.

4. 13. Nasopharynx and mucosa associated lymphatic tissue : studies on mucosal immunity, nasopharyngeal colonization with non-encapsulated non-typable Haemophilus influenzae and local administration of immunoglobulin in the upper respiratory tract

   Författare :Karin Lindberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Nasopharyngeal colonization with non-encapsulated Haemophilus influenzae (NTHI) frequently occurs in infants and in adults with common variable immunodeficiency (CVID), but is rarely found among healthy adults. In children with recurrent episodes of acute otitis media (RAOM), NTHI is more common than in healthy individuals. LÄS MER

5. 14. Bacterial Outer Membrane Vesicles. Mediators of virulence and antibiotic resistance

   Författare :Viveka Schaar; Malmö Klinisk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; Moraxella catarrhalis; epithelial cells; beta-lactamase; non-typeable Haemophilus influenzae; outer membrane vesicles; polymicrobial infections; UspA1;

   Sammanfattning : Outer membrane vesicles (OMV) have the size of nanoparticles and are released from the outer membrane of most Gram-negative bacteria. The OMV reflect the composition of the bacterial outer membrane, including lipids and virulence factors specific for the pathogen, and are involved in pathogenesis and bacterial survival. LÄS MER

7. 15. Monocytes and dendritic cells : roles during human influenza and hantavirus infections

   Författare :Sindhu Vangeti; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Viruses infect a vast majority of the other species on the planet and rarely leave the host undamaged. Most human viruses need to infect an individual to replicate and disseminate, and must contend with the full force of the human immune system. LÄS MER
