1/4. Fatal bacteremic pneumonia caused by aeromonas hydrophila in a previously healthy child.aeromonas hydrophila sepsis and pneumonia are rare diseases in children that carry a high mortality rate. We report a case of fatal bacteremic pneumonia caused by A. hydrophila in a previously healthy 5-year-old child. The source of infection was not determined and the child died within 4 hours of admission. In children who develop a fulminant disease of pneumonia with or without sepsis, particularly those who have underlying medical conditions, a possible A. hydrophila infection, though rare, should be considered. More reported cases are needed to establish the epidemiologic features of this disease in children.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
2/4. Severe community acquired pneumonia associated with a desquamating rash due to group A beta-haemolytic streptococcus.In recent years frequent and severe infections due to group A beta-haemolytic streptococci have been recognised with increasing frequency. Group A streptococcal pneumonia remains a rare disease occurring sporadically in contrast to epidemics in the past. The association between group A streptococcal pneumonia and a desquamating skin rash typical of scarlet fever has rarely been reported.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
3/4. diagnosis of ornithosis by cell culture and polymerase chain reaction in a patient with chronic pneumonia.We report the case of a woman who had pneumonia due to chlamydia psittaci. A chlamydia species was determined to be the causative agent of the pneumonia because it was isolated from bronchoalveolar lavage fluid, because it could be detected in lung biopsy specimens by the direct immunofluorescence technique, and because chlamydia-specific antibodies could be detected by ELISA and microimmunofluorescence. The infectious agent could not be identified at the species level with use of serological techniques, but the isolate was determined to be C. psittaci by PCR with use of species- and genus-specific sequences within the chlamydial lipopolysaccharide biosynthesis gene gseA. The case reported herein exemplifies the problems encountered in diagnosing ornithosis and shows that isolation of the etiologic agent followed by identification of the species by PCR is helpful in diagnosing this rare disease. In addition, the findings in our case show that laboratory personnel who are conducting tests for chlamydia pneumoniae should be aware of the risk of accidentally isolating highly infectious C. psittaci organisms.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
4/4. bronchiolitis obliterans organizing pneumonia mimicking community-acquired pneumonia.BACKGROUND: bronchiolitis obliterans organizing pneumonia is a rare disease that mimics infectious pneumonia. Most patients respond well to corticosteroid therapy. methods: We report a single case and findings from an English language literature search of medline using key words "bronchiolitis obliterans organizing pneumonia." RESULTS AND CONCLUSIONS: bronchiolitis obliterans organizing pneumonia should be considered when a patient with pneumonia does not respond to antibiotics and has multiple patchy infiltrates and characteristic bronchoalveolar lavage patterns. A tissue sample is required for definitive diagnosis. infection by a multiresistant organism can occur with multiple antibiotic therapy and concomitant use of corticosteroids, particularly when no initial infecting organism is identified.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
