Summary
Diagnosing cutaneous lupus erythematosus (CLE) involves a multi-faceted approach including skin biopsy and lab tests. Current treatments focus on antimalarials, with ongoing research into novel therapies for refractory cases.
Area of Science:
- Dermatology and Immunology
Context:
- Cutaneous lupus erythematosus (CLE) diagnosis requires careful evaluation to distinguish subtypes and exclude systemic involvement.
- Standard diagnostic tools include patient history, clinical assessment, skin biopsy (histopathology, immunofluorescence), and laboratory screening.
Purpose:
- To outline a comprehensive diagnostic strategy for CLE, including differential diagnoses and systemic involvement assessment.
- To review current and emerging treatment options for CLE, emphasizing the role of antimalarials and the need for new interventions.
Summary:
- A validated scoring system for CLE activity, based on lesion morphology and location, has been recently developed.
- Antimalarials remain the primary treatment for all CLE subtypes.
- Novel biologic agents show promise for autoimmune diseases, but require specific trials for CLE patients, especially those unresponsive to standard care.
Impact:
- Provides clinicians with a structured approach to CLE diagnosis and management.
- Highlights the need for further research into targeted therapies for CLE.
- Aims to improve patient outcomes by facilitating accurate diagnosis and appropriate treatment selection.

01:30Skin 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.

01:26Nephrotic Syndrome II : Assessment and Medical Management
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document any history...
01:24Nephrotic Syndrome III : Nursing Management
Nursing management for nephrotic syndrome adapts as the disease progresses, with strategies evolving to address advancing symptoms and complications.Early-Stage Management In the early stages, nursing interventions for nephrotic syndrome resemble those used in managing acute glomerulonephritis, focusing on symptom monitoring, fluid balance, and managing mild to moderate edema.Vital Signs: Regularly monitor blood pressure, pulse, respiratory rate, and temperature to promptly identify...

01:27Acne 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...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
