Objectives: To determine the antimicrobial susceptibility patterns of Streptococcus pneumoniae and Haemophilus influenzae, two bacterial pathogens commonly associated with communityacquired pneumonia. Design: Cross-sectional study. Setting: Bacterial isolates were obtained from adults suspected to have community-acquired pneumonia and who sought treatment at two city council clinics in Nairobi, Kenya. Susceptibility to antimicrobial agents was performed using a microdilution broth method, according to the criteria set by the National Committee for Clinical Laboratory Standards. Results: A total of 277 S. pneumoniae and 58 H. influenzae were obtained from 536 adults examined in the period January 1998 to December 1999. Of the 277 S. pneumoniae, only 56.7% were susceptible to penicillin and 7.6% of strains were resistant to two or more antimicrobial agents. Of the 58 H. influenzae strains, 91.4% were sensitive to ampicillin, with 6.8% resistant to two or more antimicrobial agents. 8.6% were ß-lactamase producers and accounted for the entire ampicillin-resistant population. Conclusion: The prevalence of resistance to penicillin and other commonly used antibiotics among pneumococci is high and the large number of multi-resistant strains among H. influenzae is a cause for concern. The prudent use of antibiotics in treatment of pneumonia and other infections should be advocated to minimise spread of resistance.

The coronavirus disease 2019 (COVID-19) has a broad spectrum of manifestations. Neurological complications are not uncommon in patients with COVID-19. We report the case of a middle-aged man who presented with a cough and fever. He had a decreased oxygen saturation and required supplementary oxygen therapy. During his stay, he developed an unexplained seizure. Computed tomography of the brain revealed vasogenic edema located posteriorly. Subsequently, magnetic resonance imaging demonstrated subcortical white-matter hyperdensities, in keeping with the diagnosis of posterior reversible encephalopathy syndrome, an exceedingly rare manifestation in COVID-19. This condition should be kept in mind when encountering unexplained neurological manifestations that developed in patients with COVID-19.
