Infection01:20

Infection

10.2K
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...

Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

3.3K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Pulse Assessment Sites01:11

Pulse Assessment Sites

2.0K
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Epistaxis01:30

Epistaxis

374
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Teeth01:15

Teeth

1.4K
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Ankle Joint01:10

Ankle Joint

2.3K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Area of Science:

  • Dermatology
  • Infectious Diseases
  • Viral Illnesses

Background:

  • Pernio-like lesions, commonly known as "COVID toes," have emerged as a notable dermatological manifestation.
  • The association between these lesions and coronavirus disease 2019 (COVID-19) requires careful consideration in clinical practice.
  • Understanding the differential diagnoses for pernio and related skin conditions is crucial as patient volumes increase.

Purpose of the Study:

  • To explore the potential etiologies of pernio and pernio-like lesions.
  • To provide guidance on the diagnostic workup for patients presenting with these symptoms.
  • To suggest appropriate management strategies for affected individuals.

Main Methods:

  • Literature review of studies and case reports on pernio-like lesions.
  • Analysis of the association between skin manifestations and COVID-19.
  • Discussion of differential diagnoses and clinical presentation.

Main Results:

  • "COVID toes" represent a spectrum of pernio and pernio-like lesions.
  • These lesions can be a sign of COVID-19 infection, but other causes must also be evaluated.
  • A systematic approach to diagnosis and management is necessary.

Conclusions:

  • Dermatologists should consider COVID-19 in the differential diagnosis of new-onset pernio-like lesions.
  • Appropriate diagnostic testing and clinical evaluation are essential.
  • Timely management can improve patient outcomes for both infectious and non-infectious causes.
