Summary
Tinea incognito, a fungal infection, worsens with incorrect steroid use. Early diagnosis and microscopic confirmation are crucial to avoid misdiagnosis as eczema.
Area of Science:
- Dermatology
- Mycology
Background:
- Tinea incognito is a fungal infection that can be misdiagnosed.
- Glucocorticoids can exacerbate dermatophyte infections.
Observation:
- A patient presented with persistent, worsening skin lesions after self-treatment for presumed eczema.
- Physical examination revealed extensive erythematous-infiltrative lesions with pustules on the thighs and buttocks.
Findings:
- Direct mycological examination and culture confirmed dermatophytes, diagnosing tinea incognito.
- The patient was treated with topical terbinafine and oral itraconazole.
Implications:
- Tinea incognito presents non-specifically, mimicking other skin conditions like eczema.
- Microscopic confirmation is vital before prescribing treatments to prevent exacerbation.
- Dermatological consultation is recommended for uncertain diagnoses.

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...

01:10PPE Use in Healthcare Settings II: Doffing
1.2K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Types of Quasi-intentional Torts in Healthcare
Quasi-intentional torts in healthcare involve acts where intent is not directed to harm an individual but results in harm due to careless or reckless speech.
