Gemella haemolysans Infection in Total Hip Arthroplasty

A Case Report of Gemella haemolysans Keratitis After Refractive Surgery

Purpose

Systematic review of Gemella haemolysans infection associated with ophthalmology, and to summarize the clinical characteristics of Gemellahaemolysans keratitis after refractive surgery.

Methods

Case report and literature review.

Results

We report an 18-year-old man who developed corneal infection after Trans-PRK, and the culture results of lesion specimens confirmed G. haemolysans keratitis. He was treated with fortified topical antibiotics, and clinical improvement was noted shortly after treatment. Resolution of keratitis was achieved at 1 month. Then, a systematic review of the reported cases of ocular G. haemolysans infection was conducted. We summarized clinical manifestations of G. haemolysans infection in cornea.

Conclusion

We reported a case of G. haemolysans keratitis infection after refractive surgery, and reviewed the literature of ocular G. haemolysans infection.

A Rare Case of Gemella haemolysans Infection of Knee Arthroplasty

Gemella haemolysans is a facultative, catalase-negative, anaerobic, gram-positive cocci. It is known to mostly cause endocarditis, meningitis, peritonitis, and cerebral abscesses. However, it is extremely rare for this organism to cause infections of an orthopedic nature, with only a single report of infection in total knee arthroplasty (TKA). We present a rare case of knee arthroplasty infection caused by G. haemolysans four years after an uncomplicated TKA procedure.
