Spectrum of Bacteria in Nipple Discharge of Patients with Duct Ectasia in Iraqi Women
Abstract
ABSTRACTBackground: Duct ectasia is a dilatation in one or more of the larger lactiferous duct filled with a stagnant brown or green secretion, which may or may not discharge through the nipple.
Objective: To identify the aerobic and the anaerobic microorganisms which can be related to the etiology of duct ectasia and the relation of duct ectasia to smoking.
Methods: The patients were divided into two groups. Group I comprised 50 patients with coloured nipple discharge (duct ectasia group), and group II (the control group) was composed of 50 patients without nipple discharge. The culture media used were thioglycolate broth, blood agar, chocolate agar and MacConkey agar.
Results: The most prevalent bacteria were Staphylococcus aureus and Staphylococcus epidermidis. The groups were indeed homogeneous, and the only difference found was with regards to smoking. In the group of patients with nipple discharge, 26% were smokers, while in the control group (no discharge), only 4% of the patients smoked (p value 0.03). The genesis of duct ectasia may be a non-infectious inflammatory process.
Conclusion: This study indicates that the genesis of duct ectasia may be a non-infectious inflammatory process.
Keywords: Duct ectasia, Nipple discharge, Bacterial infection.
