Acne Infection

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 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 I: Introduction

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Staphylococcal Skin Infections

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 Disorders

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...

Area of Science:

Dermatology
Epidemiology

Background:

Atopic dermatitis (AD) is a chronic skin condition, typically diagnosed in childhood.
Diagnosing adult AD can be challenging due to atypical presentations and limited lesion extension.

Purpose of the Study:

To investigate the epidemiological and clinical characteristics of adult atopic dermatitis.
To identify factors influencing adult AD presentation and diagnosis.

Main Methods:

Retrospective review of medical files for 332 adult atopic dermatitis patients.
Data collected included family/personal history of atopy, age at onset, lesion characteristics, IgE levels, and allergy testing (skin prick and patch tests).

Main Results:

Adult AD is more prevalent in females, with onset often occurring in the third decade of life.
The disease frequently affects limb flexures, eyelids, perioral areas, forehead, cheeks, and neck, typically presenting as mild to moderate.
Intrinsic AD accounted for 30.4% of cases, and 23.8% showed positive patch-test reactions to chemical allergens.

Conclusions:

Understanding the distinct epidemiological and clinical features of adult AD is crucial for accurate diagnosis and management.
Positive patch-test reactions in adult AD patients are significant and can impact career choices and hand dermatitis development.
