Streptococcus milleri head and neck abscesses: a case series

Area of Science:

• Infectious Diseases
• Microbiology
• Otolaryngology

Background:

• Streptococcus milleri infections, particularly head and neck abscesses, are infrequently reported in clinical literature.
• A better understanding and awareness of these infections are needed.

Purpose of the Study:

• To review cases of head and neck abscess caused by Streptococcus milleri.
• To analyze antibiotic sensitivity patterns for S. milleri infections.
• To compare findings with existing literature.

Main Methods:

• Retrospective review of 7 cases of head and neck abscess due to S. milleri.
• Analysis of patient demographics, clinical presentation, and treatment outcomes.
• Assessment of antibiotic sensitivity patterns, focusing on penicillin G, cephalexin, and erythromycin.

Main Results:

• All S. milleri isolates were sensitive to penicillin G, cephalexin, and erythromycin.
• Six out of seven patients recovered after surgical intervention and intravenous antibiotics.
• One patient succumbed to overwhelming sepsis.

Conclusions:

• S. milleri should be considered in head and neck abscesses, especially with dental involvement.
• Empiric therapy with penicillin G, cephalexin, or erythromycin is a reasonable starting point.
• Close monitoring for airway compromise and distant complications is crucial.
