Primary Healthcare Services01:30

Primary Healthcare Services

Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

Secondary Healthcare System01:11

Secondary Healthcare System

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...
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...
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...
Traditional Level Of Health Care System01:26

Traditional Level Of Health Care System

The levels of care describe the services provided in the healthcare system. Accordingly, there are six levels of the traditional healthcare system in the US: preventive, primary, secondary, tertiary, restorative, and continuing healthcare. A nurse must understand how the healthcare industry organizes and provides services within these levels of care.
The preventive healthcare service includes tests for screening. Preventive health care services include identifying and reducing disease risk...
Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...

Area of Science:

  • Dermatology
  • Wound Healing
  • Pathogenesis of Scarring

Background:

  • Keloids are a frequent dermatological issue encountered in primary care settings.
  • Managing keloids poses significant challenges due to high recurrence rates despite various treatments.
  • Incomplete understanding of keloid formation pathogenesis hinders effective treatment strategies.

Purpose of the Study:

  • To review current literature on keloid clinical features, pathogenesis, and management.
  • To highlight the specific difficulties primary care physicians face when treating keloids.
  • To provide an updated overview for clinicians managing keloid patients.

Main Methods:

  • Comprehensive literature search of recent studies on keloids.
  • Synthesis of information regarding keloid presentation and etiology.
  • Analysis of current therapeutic interventions and their efficacy.
  • Focus on challenges pertinent to primary care practice.

Main Results:

  • Keloid recurrence remains a significant clinical problem.
  • Multiple therapeutic interventions show limited success in preventing recurrence.
  • Pathogenesis of keloids is not fully elucidated, impacting treatment development.
  • Primary care physicians require specialized knowledge for effective keloid management.

Conclusions:

  • Definitive keloid treatment is lacking due to incomplete understanding of pathogenesis.
  • Improved management strategies are needed, particularly for primary care.
  • Further research into keloid formation is crucial for advancing treatment options.
