AI Article Synopsis
- Foot intertrigo, often caused by dermatophytes and yeasts, can develop into a complex infection involving multiple organisms due to factors like moisture.
- A study of 84 patients found bacteria like coagulase-negative staphylococci and Pseudomonas aeruginosa as prominent pathogens, with many patients presenting mixed infections.
- The research highlights the importance of identifying pathogens and predisposing factors, such as exposure to spa pools, to improve treatment and prevent complications in toe web infections.
Article Abstract
Background: Foot intertrigo, occurring in the interdigital space, is mostly caused initially by dermatophytes and yeasts and less frequently by gram-negative and gram-positive bacteria. With time, a "complex" may develop in the setting of moisture and maceration that contains multiple fungal and bacterial organisms.
Methods: We examined and sampled 84 patients with toe web intertrigo for bacteriologic and mycologic studies.
Results: In the culture media, the prominent isolated pathogens as single agents were coagulase-negative staphylococci in 17.9% of patients, which is assessed as contamination from skin flora; Pseudomonas aeruginosa in 16.7%; dermatophytes, Corynebacterium minutissimum, and Staphylococcus aureus each in 11.9%; beta-hemolytic streptococcus in 2.4%; and Proteus mirabilis in 1.2%. However, we recovered double pathogens from patients with foot intertrigo as mixed infection in 19 patients (22.6%). The most common predisposing factors were exposure to spa pools and ablutions.
Conclusions: Several pathogens and factors might play a role in toe web infections. Therefore, clinical and microbiologic studies are suggested to assist in the selection of appropriate treatment and the prevention of important complications of toe web infections.

Dermatology Department, CHU de Nantes, Hôtel Dieu, 1 Place Alexis-Ricordeau, 44093 Nantes, France.
Article Synopsis
- Toe-web (TW) intertrigo is a painful skin condition primarily caused by Gram-negative bacteria, often accompanied by eczema, which can lead to significant functional disability.
- A study was conducted to assess the effectiveness of a standardized treatment plan using topical corticosteroids over a 6-month follow-up for patients with GNB-TW intertrigo.
- Results showed no significant difference in disease duration between patients treated with the standardized plan and those treated without it, but relapses were less frequent in the standardized cohort.

Article Synopsis
- Squamous cell carcinoma (SCC) is a common type of skin cancer that can affect the nails, exemplified by a 60-year-old male patient who developed a painful ulcer in his foot due to a prior misdiagnosis of a fungal infection.
- Dermatological examination showed characteristics of SCC, and although the initial biopsy indicated keratoacanthoma, it did not reveal malignant features, leading to the eventual identification of moderately differentiated SCC in a follow-up biopsy.
- Successful surgical resection was performed to treat the SCC, highlighting the importance of accurate pathology understanding and biopsy techniques in preventing progression of this form of skin cancer.

Institute of Dermatology, Department of Medicine, University of Udine, Udine, Italy.
Article Synopsis
- The study aimed to assess the diagnostic accuracy of ultraviolet-induced fluorescence (UVF) dermoscopy for various non-cancerous skin conditions compared to traditional polarized light dermoscopy.
- Researchers evaluated 208 patients with different dermatoses that might show UV-induced signs, applying standardized comparisons of both UVF and polarized dermoscopic findings.
- Significant UVF responses were observed in several conditions, linking specific fluorescence colors to particular skin issues, helping to improve clinical diagnosis and understanding of dermatoses.
Bacteriological profile and frequency of antibiotic resistance in the infected diabetic foot.

Article Synopsis
- The diabetic foot (DF) poses significant public health concerns, with infections being a primary cause of amputations among patients, particularly those with type 2 diabetes.
- A study analyzed 150 patients over two years, revealing that common foot lesions often stem from inter-toe irritation and trauma, with infectious lesions leading the complications.
- Findings highlighted a prevalence of Gram-negative bacteria, primarily Escherichia coli and Pseudomonas aeruginosa, with a critical focus on antibiotic resistance; effective management remains inadequate, emphasizing the importance of preventive care.
