Case Reports in Dermatology
|March 30, 2022
Summary
Face masks can trigger demodicosis, a skin condition caused by Demodex mites, in susceptible individuals. This case report highlights the link between prolonged mask use and the onset of this mite infestation.
Area of Science:
- Dermatology
- Parasitology
- Microbiology
Background:
- Demodex mites are common ectoparasites residing in human pilosebaceous units.
- Increased Demodex mite density can lead to skin disorders collectively termed demodicosis.
- The COVID-19 pandemic necessitated prolonged face mask usage, altering facial skin microenvironments.
Observation:
- A 46-year-old female developed a rash characterized by dry, itchy, erythematous to purpuric patches with follicular scales on her cheeks and chin.
- Symptoms began with a burning and itching sensation after wearing a surgical mask for over 8 hours daily for three weeks.
- The rash showed minimal improvement with topical steroids and mask changes, recurring upon treatment cessation.
Findings:
- This is the first reported case of demodicosis associated with prolonged face mask use.
- Standardized skin surface biopsy confirmed abnormal proliferation of Demodex mites.
- Clinical symptoms resolved completely following oral ivermectin therapy.
Implications:
- Prolonged face mask use may act as a trigger for demodicosis in predisposed individuals.
- Understanding the interplay between mask-wearing and skin conditions is crucial for public health.
- Oral ivermectin demonstrates efficacy in treating mask-associated demodicosis.

01:19Masking and Demasking Agents
2.7K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.

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.

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...

01:15Reticular Dermis
3.3K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
