Summary
French dermatologists developed new criteria to classify moderate psoriasis, focusing on quality of life and symptom impact. This aims to improve treatment for patients with psoriasis.
Area of Science:
- Dermatology
- Clinical Practice Guidelines
Background:
- Current psoriasis severity scores may misclassify patients with limited lesions but significant quality of life impairment.
- This can lead to inappropriate under- or overtreatment of psoriasis.
Purpose of the Study:
- To establish consensus on clinical criteria for classifying psoriasis severity in French clinical practice.
- Focus on accurately identifying moderate psoriasis, particularly in cases with limited skin involvement but substantial patient impact.
Main Methods:
- A modified Delphi method was employed with a panel of French dermatologists.
- A 22-item questionnaire was used, with consensus defined by specific Likert scale score and median thresholds across two rounds.
Main Results:
- Fifteen items (68%) achieved strong consensus, and four (18%) achieved good consensus.
- Consensus was reached on clinical dimensions including location, symptoms, patient perception, and quality of life impact.
- Criteria for moderate psoriasis include quality of life impairment, special area involvement, uncontrolled symptoms, and treatment history.
Conclusions:
- The developed criteria can assist physicians in classifying moderate psoriasis more accurately.
- Improved classification is expected to enhance treatment strategies for patients with moderate psoriasis.

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

27
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...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

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...

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...
