Skin Diseases and Disorders

5.0K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

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...

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Drug Dosing: Infants and Children

156
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

117
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Drug Distribution

180
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Summary

Allergic contact dermatitis (ACD) is increasingly common in children, often requiring patch testing for diagnosis. Management focuses on identifying and avoiding specific allergens like nickel and fragrances.

Area of Science:

  • Pediatric Dermatology
  • Allergy and Immunology

Background:

  • Allergic contact dermatitis (ACD) is increasingly recognized in children, contrary to previous beliefs of its rarity.
  • Factors such as changing trends in toys, hobbies, and personal care products may contribute to rising ACD prevalence in pediatric populations.

Purpose of the Study:

  • To review the current understanding of allergic contact dermatitis (ACD) in children.
  • To highlight diagnostic approaches and common allergens implicated in pediatric ACD.

Main Methods:

  • Review of recent studies and patch testing data in pediatric populations.
  • Discussion of clinical features differentiating ACD from atopic dermatitis.
  • Reference to the 2018 expert consensus-derived pediatric baseline series for patch testing.

Main Results:

  • Nickel, cobalt, neomycin, balsam of Peru, fragrance mixes I and II, methylisothiazolinone, formaldehyde, and lanolin are frequently identified allergens in children with ACD.
  • Patch testing is becoming more common for diagnosing ACD in children.
  • ACD can coexist with atopic dermatitis, necessitating careful clinical evaluation.

Conclusions:

  • Allergic contact dermatitis (ACD) is a significant and growing concern in pediatric dermatology.
  • Accurate diagnosis via patch testing and diligent allergen avoidance are crucial for managing pediatric ACD.
  • Understanding common pediatric allergens is key to effective prevention and treatment strategies.
