Insights

Narrow-band UVB (NB-UVB) phototherapy shows promise for treating pediatric psoriasis and atopic dermatitis (AD), with good tolerability. Longer follow-up is needed to confirm long-term safety and efficacy in children.

Area of Science:

  • Pediatric Dermatology
  • Phototherapy Research
  • Dermatologic Treatments

Background:

  • Phototherapy is established for adult skin conditions but limited in children due to cancer concerns.
  • Few trials exist on pediatric phototherapy efficacy and safety.
  • Concerns about long-term carcinogenic potential restrict its use in pediatric populations.

Purpose of the Study:

  • To evaluate the efficacy and safety of narrow-band UVB (NB-UVB) phototherapy.
  • To assess treatment outcomes for children diagnosed with atopic dermatitis (AD) and psoriasis.

Main Methods:

  • Retrospective review of 129 pediatric patients with psoriasis and AD.
  • Treatment administered between 1998 and 2006 using NB-UVB.
  • Analysis of treatment outcomes, including disease clearance and adverse events.

Main Results:

  • Clearance achieved in 50% of pediatric psoriasis patients.
  • Clearance achieved in 25% of pediatric atopic dermatitis patients.
  • NB-UVB was well-tolerated; one suspected case of melanoma in situ was noted.

Conclusions:

  • NB-UVB is a potential therapeutic option for pediatric psoriasis and AD.
  • Annual dermatologic observation is recommended for children undergoing phototherapy.
  • Extended follow-up studies are essential to ascertain the true carcinogenic risk of UV therapy in children.

Acne Infection01:27

Acne 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...

Pharmacokinetics in Pediatric Patients: Drug Excretion

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...

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material,  molecules absorb light depending on the energy required for electronic transitions. As a result...
UV–Vis Spectrum01:30

UV–Vis Spectrum

When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.     
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar absorptivity (ε) or log ε on the y-axis (ordinate)...
Mutations01:35

Mutations

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.
Chromosomal Alterations Are Large-Scale Mutations
While point mutations are changes in a single nucleotide in...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
