Healing II: Complications01:24

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
Skin Cancer01:30

Skin Cancer

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...
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
Skin Diseases and Disorders01:23

Skin Diseases and Disorders

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...
Growth of Cartilage and Bone Tissue01:27

Growth of Cartilage and Bone Tissue

Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Summary

Ear cartilage piercings, especially those done in adolescence or later, are more prone to keloid formation. Prolonged wound healing due to infection significantly contributes to these post-piercing keloids.

Area of Science:

  • Plastic Surgery
  • Dermatology
  • Wound Healing

Background:

  • Keloids are abnormal scars that can develop after skin injury.
  • Ear piercings, particularly in the cartilage, are a common trigger for keloid formation.

Purpose of the Study:

  • To identify the key factors contributing to the development of keloids following ear piercings in the auricular cartilage.
  • To analyze the relationship between piercing characteristics and keloid occurrence.

Main Methods:

  • An observational study was conducted involving 50 patients with post-earpiercing keloids affecting the auricular cartilage.
  • Data collected included age at piercing, piercing site, method, jewelry type, and post-piercing complications like infection.
  • Statistical analysis used Fisher exact and Wilcoxon rank sum tests.

Main Results:

  • Keloids exclusively developed at cartilage piercing sites, with a mean age of piercing at 22.32 years.
  • All patients with cartilage keloids experienced post-piercing infection.
  • Lobule piercings, done at a younger mean age (4.52 years), showed a significantly lower infection rate.

Conclusions:

  • Adolescent or later ear cartilage piercing is a significant risk factor for keloid development.
  • Prolonged wound healing, often exacerbated by infection, is a critical factor in auricular cartilage keloid formation.
