ABSTRACT
Haemophilus influenzae (H. influenzae) is a facultative anaerobe, pleomorphic Gram-negative coccobacillus capable of causing various respiratory and blood stream infections. Introduction of childhood immunization against H. influenza type b has decreased its prevalence. Invasive infection with non-typeable H. influenzae is increasing specially in vulnerable population. We present a case of a 69-year-old female who developed septic shock due to H. influenzae infection. She was also found to have influenza A infection in bronchoalveolar lavage (BAL) sample although initial test with nasopharyngeal swab was negative. This case report highlights the fact that in patients with high clinical suspicion, negative nasopharyngeal swab with polymerase chain reaction may not rule out influenza infection and BAL may be necessary to confirm the diagnosis and H. influenzae can be causing bacterial superinfection in such patients. She was appropriately treated with third-generation cephalosporin for H. influenzae and with oseltamivir for influenza A. Her condition improved significantly with the treatment.
ABSTRACT
The influence of the changing climate on individual snowstorms has been uncertain, in part due to the use of coarse model simulations. Now, research employing more detailed simulations finds fewer and smaller snowstorms as a result of warming, with a reduction in the amount and extent of extreme snowfall.
