Abstract:
Gram-negative bacterial toe-web infections (GNBTWI's) are relatively under-recognized among physicians. Even though skin infections are usually thought to involve gram-positive bacteria, gram-negative organisms have a particular affinity for the toe-web. We present two patients with GNBTWI's who presented with maceration of the toe-webs, vesiculopustules and a hyperkeratotic rim. Treatment includes using both oral and topical antibiotics along with antifungals to treat co-existing dermatophyte infections. Awareness of this condition is particularly important for primary care physicians in West Virginia, as a few of the potential risk factors include wearing occlusive footwear, such as work boots, and type II diabetes mellitus.
Insights
Gram-negative bacterial toe-web infections (GNBTWI
Area of Science:
- Dermatology and Microbiology
Background:
- Gram-negative bacterial toe-web infections (GNBTWI) are often overlooked by medical professionals.
- Gram-negative bacteria show a specific preference for the toe-web environment, unlike typical skin infections.
Observation:
- Two cases of GNBTWI presented with macerated toe-webs, vesiculopustules, and a hyperkeratotic rim.
- Co-existing dermatophyte infections were noted in the observed cases.
Findings:
- Successful treatment involved a combination of oral and topical antibiotics.
- Antifungal therapy was crucial for addressing concurrent dermatophyte infections.
Implications:
- Increased physician awareness of GNBTWI is essential, particularly in regions like West Virginia.
- Risk factors such as occlusive footwear and type II diabetes mellitus should be considered in diagnosis.
