Epistaxis01:30

Epistaxis

328
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...

Decreased Body Temperature01:29

Decreased Body Temperature

771
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Skin Diseases and Disorders

4.5K
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...

Burn Injuries01:22

Burn Injuries

3.3K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Hand hygiene01:23

Hand hygiene

4.9K
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.

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

592
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Area of Science:

  • Connective tissue biology
  • Autoimmune diseases
  • Cellular microenvironment

Background:

  • Mesenchymal progenitor cells are crucial in fibrogenesis, the process of scar tissue formation.
  • Scleroderma (systemic sclerosis, SSc) is an autoimmune disease characterized by pathological fibrosis.
  • Understanding the triggers for fibrogenesis in SSc is vital for developing targeted therapies.

  • To elucidate the role of the connective tissue microenvironment in SSc-related fibrosis.

Main Methods:

  • Analysis of mesenchymal progenitor cell activation.
  • Utilizing blister fluid from patients with scleroderma (systemic sclerosis).

Main Results:

  • Skin blister fluid from scleroderma patients preferentially activated mesenchymal progenitor cells.
  • These findings highlight specific cellular interactions within the SSc microenvironment.
