Accessory Structures of the Skin: Hair Growth and Types01:20

Accessory Structures of the Skin: Hair Growth and Types

2.2K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

130
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

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,...

Pharmacokinetics in Pediatric Patients: Drug Excretion

148
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...

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...

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...

Area of Science:

  • Dermatology
  • Autoimmune Diseases
  • Pediatrics

Background:

  • Alopecia areata (AA) is a non-scarring hair loss disorder with autoimmune origins.
  • It is the third most common dermatologic condition in children, with a lifetime risk of 1-2%.

Purpose of the Study:

  • To provide physicians with comprehensive information on the clinical presentation, diagnosis, evaluation, and management of pediatric alopecia areata.
  • To enhance understanding of this common childhood dermatologic condition.

Main Methods:

  • A comprehensive literature search was conducted using "Alopecia areata" in PubMed.
  • Included studies covered epidemiology, clinical diagnosis, investigations, comorbidities, and treatment, encompassing meta-analyses, RCTs, clinical trials, observational studies, and reviews published in English.
  • A narrative synthesis of retrieved articles was performed.

Main Results:

  • Pediatric alopecia areata is diagnosed via history and clinical presentation, typically presenting as patchy, non-scarring scalp hair loss.
  • Key diagnostic indicators include "exclamation point hairs" and "yellow dots" on trichoscopy, with possible nonspecific nail changes.
  • Variants include alopecia totalis, universalis, ophiasis, sisaipho, and Canitis subita, and multiple treatment options exist.

Conclusions:

  • Alopecia areata is an autoimmune disease with varied presentations and an unpredictable course.
  • While a cure is unavailable, current treatments effectively manage this disfiguring condition in children.
