BACKGROUND In Taiwan, Klebsiella pneumoniae is the predominant pathogen causing pyogenic liver abscess in patients with diabetes mellitus (DM). The purpose of our hospital-based study was to determine the predominant bacterial species causing perianal abscess in hospitalized patients with and without DM in Taiwan. METHODS Data on patients admitted and then operated on for perianal abscess dur...

However, it may affect other sites such as the skin, central nervous system, eyes, heart, gastrointestinal tract, and liver. We describe a rare case of GPA in which the initial manifestation was the involvement of the parotid gl...

In the setting of HIV, cerebral lesions are usually secondary to lymphoma and opportunistic infections; however, in patients with CD4 counts above 200 cells/uL, other pathologies such as pyogenic brain abscess could gain importance. The microbiology of pyogenic brain abscess has Staphylococcus and Streptococcus as the leading etiologic pathogens in immunocompetent individuals. Peptostreptococcu...
