Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Area of Science:

  • Dermatology
  • Clinical Research Methodology

Background:

  • Multiple global scales exist for acne severity grading.
  • A singular standard for acne grading is currently lacking.

Purpose of the Study:

  • To determine essential clinical components and features for a global acne grading scale.
  • The scale is intended for both research and clinical practice.
  • A Delphi process was employed to achieve consensus.

Main Methods:

  • A web-based Delphi survey was conducted with ten acne experts.
  • The survey involved three iterative rounds of questions to reach consensus.

Main Results:

  • Consensus was achieved for including primary acne lesions, number, extent, and sites of involvement.
  • Key features identified for the scale include clinimetric properties, categorization, efficiency, and acceptance.
  • Patient experiences and secondary lesions were excluded due to lack of consensus.

Conclusions:

  • An ideal acne global grading scale should encompass primary lesion characteristics, quantity, extent, and anatomical sites.
  • Essential features for the scale are clinimetric properties, categorization, efficiency, and stakeholder acceptance.
  • The Delphi panel comprised solely U.S.-based acne experts, representing a limitation.
