Skin Diseases and Disorders01:23

Skin Diseases and Disorders

5.0K
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...

Skin Cancer01:30

Skin Cancer

5.5K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Infection01:20

Infection

10.7K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Changes in Skin Color: Clinical Perspectives

3.1K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Introduction to the Integumentary System01:25

Introduction to the Integumentary System

12.5K
The integumentary system is the organ system that comprises the skin and its associated structures. It is the largest system in the human body and plays a crucial role in protecting and maintaining homeostasis. The integumentary system serves several functions including protection, regulation, sensation, and secretion.
The skin, which is the primary organ of the integumentary system, consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous tissue). The epidermis is the...

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

19.5K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Summary

The study explores skin manifestations linked to coronavirus disease 2019 (COVID-19), noting their potential for early detection. It also addresses skin issues arising from personal protective equipment (PPE) use during the pandemic.

Area of Science:

  • Infectious Diseases
  • Dermatology
  • Public Health

Background:

  • The emergence of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) caused the COVID-19 pandemic.
  • Cutaneous manifestations associated with COVID-19 are increasingly recognized globally.
  • The use of personal protective equipment (PPE) has led to various skin conditions.

Purpose of the Study:

  • To investigate the association between dermatological signs and COVID-19 for potential early diagnosis.
  • To highlight the dermatological adverse effects related to PPE usage.
  • To inform dermatologists on managing inflammatory skin conditions in COVID-19 patients.

Main Methods:

  • Review of reported cases and existing literature on COVID-19 and skin manifestations.

  • Analysis of dermatological conditions observed in patients with COVID-19.
  • Examination of adverse skin reactions linked to personal protective equipment (PPE).

    • Main Results:

    • COVID-19 presents with diverse dermatological manifestations, including rashes, urticaria, livedo reticularis, and acrocyanosis.
    • Personal protective equipment (PPE) use is associated with adverse skin effects like contact dermatitis, acne, and infections.
    • Management of inflammatory dermatoses in COVID-19 patients requires careful consideration of medication dosages.

    Conclusions:

    • Cutaneous signs can aid in the early recognition of SARS-CoV-2 infection.
    • Adherence to safety protocols is crucial to mitigate PPE-related skin issues.
    • Ongoing research and global collaboration are vital for managing extra-pulmonary manifestations of COVID-19 and developing countermeasures against evolving viral strains.
