Summary
Rosacea, a chronic skin condition affecting 10% of people, presents with varied signs and symptoms. Current classification systems, like the National Rosacea Society
Area of Science:
- Dermatology
- Clinical Science
Context:
- Rosacea is a prevalent chronic skin disease impacting up to 10% of the population.
- It manifests with diverse signs and symptoms, primarily in the centrofacial region.
- Existing understanding and classification of rosacea's varied expressions remain challenging.
Purpose:
- To review and discuss the current understanding and classification of rosacea.
- To highlight the limitations and controversies in existing diagnostic and staging systems.
- To present the National Rosacea Society's classification framework.
Summary:
- Rosacea encompasses various clinical presentations, previously classified into stages or variants.
- The National Rosacea Society (NRS) proposes a classification into four subtypes (erythematotelangiectatic, papulopustular, phymatous, ocular) and one variant (lupoid/granulomatous).
- This NRS system utilizes diagnostic criteria for primary and secondary features and includes severity assessment suggestions, though classification remains debated pending better pathogenetic understanding.
Impact:
- Provides a framework for consistent diagnosis and assessment of rosacea.
- Highlights areas needing further research into rosacea pathogenesis.
- Aims to improve clinical management and patient care for rosacea patients.

Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.

01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:19Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...
01:30Coronary Artery Disease III: Clinical Manifestations
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
01:13Asthma 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,...
01:27Atherosclerosis II: Clinical Manifestations and Diagnostic Tests
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
