Insights

Nail psoriasis is challenging to treat, but new therapies are emerging. Recent studies highlight the need for fungal cultures due to higher infection rates in psoriatic nails.

Area of Science:

  • Dermatology
  • Mycology

Context:

  • Nail psoriasis presents significant treatment challenges.
  • Fungal infections are increasingly recognized in psoriatic nails, necessitating diagnostic cultures.
  • Recent advancements offer new therapeutic options for nail psoriasis.

Purpose:

  • To review current understanding and treatment strategies for nail psoriasis.
  • To emphasize the role of fungal infections in nail psoriasis management.
  • To discuss novel systemic and topical therapies for nail psoriasis.

Summary:

  • Nail psoriasis is notoriously difficult to manage.
  • Fungal co-infections are common in psoriatic nails, requiring cultures for accurate diagnosis and treatment.
  • Systemic treatments like cyclosporine and biologics, along with topical vitamin D/A derivatives and 8% clobetasol propionate nail lacquer, show promise for improving nail bed and matrix lesions.

Impact:

  • Improved diagnostic approaches for nail psoriasis, incorporating fungal cultures.
  • Enhanced therapeutic strategies combining systemic and topical agents for better patient outcomes.
  • Potential for novel treatments to address both skin and nail manifestations of psoriasis.

Accessory Structures of the Skin: Nails

Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

Nephrotic 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...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
