The Periodic Table and Organismal Elements

23.3K
Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.

Pharmacokinetics in Pediatric Patients: Drug Metabolism

304
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...

Minerals

1.5K
Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

586
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...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

1.2K
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

    Area of Science:

    • Pediatric Dermatology
    • Allergy and Immunology
    • Contact Dermatitis

    Background:

    • Contact dermatitis is a common skin condition in children.
    • Metal allergens like nickel, chromium, and cobalt are frequent causes of allergic contact dermatitis.
    • Patch testing is a standard diagnostic tool for identifying specific allergens.

    Purpose of the Study:

    • To determine the prevalence of metal sensitivity in children.
    • To investigate the relationship between age, sex, and metal sensitivity.
    • To identify common metal allergens in a pediatric population.

    Main Methods:

    • A cohort of 100 children underwent patch testing.
    • Standard concentrations of nickel sulfate, potassium dichromate, and cobalt chloride were used.
    • Reactions were assessed to identify positive patch test results.

    Main Results:

    • 17% of children showed positive reactions to at least one metal allergen.
    • Chromium (13%) and nickel (8%) were the most common sensitizers.
    • Older children (8-14 years) exhibited significantly higher sensitivity (32.5%) than younger children (2.66%).
    • Female children demonstrated a higher incidence of metal sensitivity compared to males.

    Conclusions:

    • Metal sensitivity is a notable issue in pediatric dermatology.
    • Age and sex are significant factors influencing metal allergen prevalence in children.
    • Patch testing is crucial for diagnosing metal-induced dermatoses in pediatric patients.
