Summary
Interdigital erythrasma, a superficial bacterial infection, is common and often mistaken for fungal infections like tinea pedis. Wood lamp examination offers a rapid and effective diagnostic method.
Area of Science:
- Dermatology
- Infectious Diseases
- Microbiology
Context:
- Erythrasma is a superficial skin infection caused by Corynebacterium minutissimum.
- It typically affects skin folds and interdigital spaces, presenting as erythematous, scaly patches with maceration.
- Characteristic coral-red fluorescence under Wood light aids diagnosis.
Purpose:
- To determine the prevalence of erythrasma in patients presenting with interdigital lesions.
- To compare diagnostic methods for interdigital erythrasma.
Summary:
- A study of 73 patients with interdigital lesions found a 32.8% prevalence of erythrasma, diagnosed via Wood light and Gram staining.
- Scaling and maceration were key clinical signs, with the fourth interdigital web most affected.
- Corynebacterium isolation was unsuccessful; fungal co-infections (Candida, dermatophytes) were noted in 62.5% of cases.
Impact:
- Highlights the frequency of interdigital erythrasma and its potential misdiagnosis as tinea.
- Emphasizes the utility of Wood light examination for rapid diagnosis over challenging cultures.
- Suggests considering co-infections with dermatophytes and Candida in affected interdigital webs.

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
