Summary
Nail psoriasis affects over 30% of children with psoriasis, with pitting being common. Nail involvement in pediatric psoriasis is linked to disease severity and psoriatic arthritis.
Area of Science:
- Pediatric Dermatology
- Rheumatology
- Nail Diseases
Background:
- Limited data exists on nail psoriasis prevalence in children.
- Understanding nail involvement is crucial for comprehensive pediatric psoriasis care.
Purpose of the Study:
- To determine the prevalence and clinical features of nail psoriasis in French children.
- To identify risk factors and associations of nail involvement in pediatric psoriasis.
Main Methods:
- Multicenter, cross-sectional study across 23 French dermatology centers.
- Systematic inclusion of children with psoriasis over a 1-year period.
- Collection of nail clinical features and assessment of disease associations and comorbidities.
Main Results:
- Nail involvement observed in 32.3% of 313 children with psoriasis.
- Common nail findings included pitting (fingernails) and onycholysis/pachyonychia (toenails).
- Nail psoriasis associated with male sex, palmoplantar psoriasis, disease severity, and psoriatic arthritis.
Conclusions:
- Nail psoriasis is prevalent in children, affecting nearly one-third of cases.
- Clinical manifestations in children share similarities with adult nail psoriasis.
- Nail psoriasis in children is a significant indicator of psoriatic arthritis.

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...

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
