    Insights

    Tinea faciei, a fungal infection, is rare in infants. This study identified Trichophyton tonsurans as the cause in three infants, with family transmission noted in two cases.

    Area of Science:

    • Dermatology
    • Mycology
    • Pediatrics

    Background:

    • Tinea faciei, a superficial fungal infection of the face, is uncommon in infants.
    • Fungal infections in infants require prompt diagnosis and treatment to prevent complications.

    Observation:

    • This study reports on three infants diagnosed with tinea faciei.
    • The causative agent identified was Trichophyton tonsurans.

    Findings:

    • Microscopic examination using potassium hydroxide (KOH) was negative in two out of three infants.
    • Fungal culture confirmed Trichophyton tonsurans in all three cases.
    • Scalp infections with Trichophyton tonsurans were present in family members of two infants, suggesting transmission.

    Implications:

    • Highlights the importance of fungal cultures for diagnosing tinea faciei in infants, especially when KOH smears are negative.
    • Suggests that infants may acquire Trichophyton tonsurans infections from infected household members.
    • Emphasizes the need for considering differential diagnoses for facial rashes in infants and investigating potential sources of infection.

    Accessory Structures of the Skin: Sebaceous Glands

    A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
    These glands that produce the oils on the skin and hair are holocrine glands. The mature...

    Skin 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...

    Tonsillitis I: Introduction

    Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
    Etiology
    Three primary contributing factors have been identified.
    The Skin Microbiota01:27

    The Skin Microbiota

    The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...
    Acne Infection01:27

    Acne Infection

    Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

    Cryptococcal Meningitis

    Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
