The document discusses anatomical peculiarities of the nervous system in children. It notes that the brain mass of a newborn is 10% of body mass, and development is uneven across brain areas. For newborns, the brain is shorter and wider. Myelination begins after birth and intensifies from ages 1-2. The structure of neurons matures with age, developing nuclei, axons, and dendrites. The functioning of the nervous system also matures with age.
The document discusses several anatomical and physiological peculiarities of the nervous system in children. It notes that the brain mass is a higher percentage of body mass in newborns compared to adults, and certain areas develop more quickly than others. Neurons in newborns have less surface area covered by synapses and shorter axons compared to older children and adults. The formation of the nervous system is most important in early childhood, and negative influences in the first 18 months can cause future disturbances.
This document provides an overview of the anatomy and physiology of the gastrointestinal system in infants and children. It describes how the oral cavity, esophagus, stomach, intestines, pancreas, liver and gallbladder develop and function differently in children compared to adults. For example, the stomach is initially horizontal and increases in size with age, digestive enzyme production is lower in infants, and the liver has incomplete differentiation and functionality in newborns. It also lists some common GI symptoms in children and potential diagnostic tests.
The urinary tract includes the kidneys, ureters, bladder, and urethra. In children, the kidneys are lobed and have fewer nephrons than adults. The kidneys help regulate water, salt, and waste removal. The ureters are wider in children and the bladder holds less volume. Development of urinary control occurs between 5-6 months and 1 year of age. Common urinary symptoms in children include intoxication, dyspepsia, pain, and dysuria.
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood and regulate fluid levels. They develop fully by age 5. Assessment of the urinary system involves medical history, physical exam checking for edema and blood pressure, and lab tests like urinalysis to check for cells, proteins, and bacteria. Imaging tools like ultrasound can detect abnormalities of the kidneys, ureters, and bladder.

Common causes discussed are familial short stature, constitutional short stature, and pathological short stature. Treatment options mentioned include growth hormone, oxandrolone, IGF-1, and aromatase inhibitors.
Failure to thrive is defined as sustained weight loss or failure to gain weight resulting in a child's weight falling below normal growth curves. It can be caused by inadequate nutrition intake, increased calorie needs, or issues with absorption. Evaluation involves assessing growth charts, nutrition intake, physical exam for signs of organic disease, and laboratory tests if indicated. Management goals are nutritional rehabilitation, treating any underlying medical causes, and addressing psychosocial factors. The prognosis depends on the etiology, with psychosocial causes having risks of developmental delays and organic causes having variable outcomes based on the specific condition.
The document discusses normal child development and developmental screening. It covers the following key points:
- Normal growth and development is essential for preventing and detecting disease. Development includes increases in size and changes in function influenced by emotional and social environments.
- Child development is monitored by parents, health checks, and involves assessing gross motor, fine motor, language, social-emotional, and cognitive skills.
- Screening checks whole populations for delays, while assessment provides detailed analysis of specific developmental areas.
- Multiple factors like nutrition, stimulation, and diseases can influence motor, cognitive, language, and socio-emotional development. Standard tests are used to evaluate developmental progress and identify children who need further assessment.
Approach in children with Hepatosplenomegaly
To summarize the key points:
1. A full examination including inspection, palpation, percussion and auscultation of the abdomen should be performed to evaluate for hepatosplenomegaly.
2. Common causes include infections, hematological disorders, vascular congestion, tumors and infiltrations, and storage disorders.

The pyramidal tract (corticospinal tract) originates from motor areas of the cerebral cortex and descends through the brainstem and spinal cord. It crosses to the opposite side and terminates on internuncial neurons which connect to motor neurons in the anterior horn of the spinal cord. The extrapyramidal tracts include the rubrospinal, vestibulospinal, reticulospinal, and tectospinal tracts and are involved in motor control and coordination. Damage to upper motor neurons in the pyramidal tract causes different paralysis than damage to lower motor neurons in the spinal cord.
This document provides an overview of acute renal failure in children. It defines acute renal failure, discusses causes (pre-renal, intrinsic renal, post-renal), pathogenesis, laboratory findings, biomarkers, management including fluid resuscitation, diuretics, electrolyte abnormalities, nutrition, and indications for dialysis. Management is aimed at treating the underlying cause and maintaining fluid, electrolyte and acid-base balance until renal function recovers.
Bone marrow failure, or aplastic anemia, is a condition where the bone marrow does not produce sufficient new blood cells. It can affect red blood cells, white blood cells, and platelets separately or together. The most common type is acquired aplastic anemia, which is often caused by viral infections or medications. A patient presents with pallor, fever, bruising, and bleeding. Investigations show pancytopenia and a hypocellular bone marrow. Treatment involves blood transfusions, immunosuppressive drugs, or bone marrow transplant. The prognosis depends on the severity and treatment received, with transplant offering the best chance of cure.
The document provides information on approaching patients with potential neurodegenerative disorders, including two patient scenarios. It discusses:
1) Classifying neurodegenerative disorders as either gray matter or white matter diseases based on features like age of onset, head size, seizures, cognition, and exam findings.

Principles of Development
Cephalocaudal
Proximodistal
Cephalocaudal – refers to development as progressing from head to toe. Consider muscle development babies begin by being able to lift their head and then it progresses to ultimate control of muscles which would be walking.
Proximodistal refers to center out. Again consider the last area one gains control is the fingers.

Skeletal Growth
Skeletal Age
Epiphyses
Fontanels
The best estimate of a child’s physical maturity is skeletal age, which is a measure of development of the bones of the body.
Epiphyses are growth centers, that appear at the ends of the long end of the bones of the body. Cartilage cells continue to be produces at the growth plates of these epiphyses, which increase in number throughout childhood and then as growth continues, get thinner and disappear.
Skull growth is especially rapid between birth and 2 years of age due to large increases in brain size. At birth the bones of the skull are separated by gaps called fontanels. These gaps help during the birth process and also allow for brain development. There are 6 of these – the largest is the anterior gap. It will gradually shrink and fill in during the second year. The other fontanels are smaller and close more quickly. As the skull bones come in contact with one another, they form sutures or seams, these permit the skull to expand easily as the brain grows. The sutures will disappear when skull growth is complete, during the teen years.

At birth the brain is nearer to its adult size than any other physical structure.
Human brain has 100 to 200 billion neurons or nerve cells that store and transmit information. Between nuerons are tiny gaps or synapses, where fibers from different neurons come close together but do not touch. Neurons send messages to one another by releasing chemicals call neurotransmitters which cross the synapse. During infancy and toddlerhood, neural fibers and synapses increase dramatically. Because developing neurons require space for connective structures, as synapses form surrounding neurons will die. As neurons form connections, stimulation becomes vital for their survival. Neurons that are stimulated by input from the surrounding environment continue to establish new synapses, forming increasingly elaborate systems of communication that support more complex abilities. Neurons that are seldom stimulated soon lose their synapses, through synaptic pruning, which returns neurons not needed at the moment to an uncommitted state so they can support future development.
About half of the brain is made up of glial cells which are responsible for myelination, the coating of.

The brain displays remarkable plasticity throughout life, especially during early childhood. Early experiences shape the formation of neural connections, known as synaptogenesis, which peaks between birth and age 3 as the brain rapidly develops trillions of synapses. During this critical period, enriched environments lead to greater neural connectivity, while insufficient stimulation results in pruning of underused synapses. Later in childhood and through adulthood, plasticity enables the brain to learn, form new memories, and rewire itself in response to injury.

The document discusses key topics in infant development covered in a developmental psychology course, including motor development, brain growth, sleep patterns, and nutrition. It provides details on important milestones like the disappearance of reflexes between birth and age two. Cultural and environmental factors that can influence domains like motor skills and sleep are also addressed. Synaptic pruning in the first two years helps establish stronger neural connections by reducing unnecessary neurons. While brain development is genetically programmed, the environment can impact it through plasticity during sensitive periods.
The document discusses physical, cognitive, and motor development in infants and toddlers over the first two years of life. It covers rapid growth and changes in body size, brain development including neuron and synapse formation, sleep patterns, sensory and motor development including reflexes and motor skills, and the role of nutrition and public health measures in child development.
This document summarizes physical development in infants, including growth patterns, brain development, sleep patterns, and reflexes. It notes that infants grow rapidly in the first two years, with their head growing proportionally larger at birth and slowing over time. Brain growth involves proliferation of neurons early on and later pruning and myelination. Infant sleep involves cycling between active and quiet sleep, and cultural practices around sleep vary. Reflexes are innate responses that facilitate development but fade as voluntary control increases.
The brain undergoes significant development and changes throughout life. In early childhood, the brain rapidly forms new connections, with trillions of synapses forming by age 3. During childhood, synaptic pruning occurs, removing unused connections. Experience and environment influence which connections are strengthened and retained. Early childhood experiences are particularly important for brain development. Brain plasticity allows the brain to adapt and recover from injury through mechanisms like remapping of functions. Early intervention programs provide therapeutic support and aim to maximize development for children with disabilities or delays.

The Physical Development of the Young Child
Take a moment and think about a newborn infant--at birth, human infants are, essentially, completely vulnerable and helpless. Unlike many animals, they cannot walk, consume solid food, or manage even the most basic tasks for their own survival. This is the price we pay for our brains--we are born far less developed than many creatures. Over the course of a very short time, around two years, that helpless newborn learns to walk and talk, to manipulate objects, to engage and participate in the world around her.
This transition from a helpless newborn to a toddler or preschooler requires massive amounts of
learning
, fueled by rapid brain growth, sensorimotor development, and physical growth. The infant, from birth, uses his ability to perceive to learn and develop an understanding of the world around him.
TOPICS COVERED WILL INCLUDE:
Brain development during infancy and toddlerhood at the larger level of the cerebral cortex.
Learning through classical conditioning, operant conditioning, habituation and recovery, and imitation.
Dynamic Systems theory of motor development, highlighting cultural variations in motor development.
Gibsons’ Differentiation Theory of perceptual development.
The Development of the Brain
Brain development in the first two years of life is fascinating and awe-inspiring. Most of the physical growth of the brain occurs during the first two years of life. Neuroscience has shed light on the development of
neurons
and the
cerebral cortex
in particular. At birth, infants have approximately one hundred billion neurons. Relatively few neurons will be produced after birth. The newborn’s neurons are connected only tentatively. In the first years, essential connections between neurons form. Combined with understanding sensitive periods and the role of the environment, we have a much clearer picture of what is happening in the infant and toddler brain today than ever before.

1. The document discusses the importance of skin-to-skin contact between mothers and newborns from a neuroscience perspective. It summarizes evidence that separation from the mother is a form of toxic stress that can disrupt brain development and have lifelong negative impacts on learning, behavior, and health.
2. The author argues that reducing toxic stress for newborns is very easy and involves practices like skin-to-skin contact, attachment, bonding, and breastfeeding that allow the mother's body to regulate the infant's physiology. Public health policies should focus on supporting these early interactions between mothers and babies.

In his lecture, Prof. Pat Levitt describes the great heterogeneity of the brain, which makes people different from each other and is a significant challenge to treating people with disabilities.
This document provides an overview of infant and toddler development in the first two years. It discusses rapid physical growth and brain development during this period. The brain grows from 25% to 75% of adult size by age 2. Brain structures like neurons, axons, dendrites and synapses develop quickly through growth and pruning processes shaped by experiences. All senses are functional at birth and develop further as motor skills emerge, allowing infants to progressively interact with and learn from their environment. Caregivers play an important role in providing stimulation and experiences that support healthy development.
To highlight the importance of Early Brain & Child Development (EBCD).
To recognize some valuable nutritive materials for the development of children’s brains.
The document defines key terms related to child development and neuroscience. It describes neurons, axons, dendrites and synapses as components of the nervous system. It also defines concepts like the prefrontal cortex, sensation, perception, motor skills, malnutrition diseases, and sensitive periods in child development.
This document discusses brain development from infancy through adolescence. It notes that connections in the brain are strengthened through use and pruned away if not used. The brain grows rapidly in the first few years of life as connections are formed and then pruned away. Environmental influences shape brain development, with the earliest years seeing the most change as experiences bombard the developing brain. Brain growth continues through childhood and adolescence as different areas mature at different rates.
The document discusses neural development from fertilization through childhood. It describes the major phases of development including induction of the neural plate, proliferation, migration, aggregation, axon growth and synapse formation. It also discusses the impact of experience and deprivation on development through cases like Genie, and explores disorders like autism and Williams syndrome.

GASTROINTESTINAL INFECTIONS AND GASTRITIS
Osvaldo Bernardo Muchanga
Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort.
Receptor Discordance in Breast Carcinoma During the Course of Life
Definition:
Receptor discordance refers to changes in the status of hormone receptors (estrogen receptor ERα, progesterone receptor PgR, and HER2) in breast cancer tumors over time or between primary and metastatic sites.
Causes:
Tumor Evolution:
Genetic and epigenetic changes during tumor progression can lead to alterations in receptor status.
Treatment Effects:
Therapies, especially endocrine and targeted therapies, can selectively pressure tumor cells, causing shifts in receptor expression.
Heterogeneity:
Inherent heterogeneity within the tumor can result in subpopulations of cells with different receptor statuses.
Impact on Treatment:
Therapeutic Resistance:
Loss of ERα or PgR can lead to resistance to endocrine therapies.
HER2 discordance affects the efficacy of HER2-targeted treatments.
Treatment Adjustment:
Regular reassessment of receptor status may be necessary to adjust treatment strategies appropriately.
Clinical Implications:
Prognosis:
Receptor discordance is often associated with a poorer prognosis.
Biopsies:
Obtaining biopsies from metastatic sites is crucial for accurate receptor status assessment and effective treatment planning.
Monitoring:
Continuous monitoring of receptor status throughout the disease course can guide personalized therapy adjustments.
Understanding and managing receptor discordance is essential for optimizing treatment outcomes and improving the prognosis for breast cancer patients.
This presentation gives information on the pharmacology of Prostaglandins, Thromboxanes and Leukotrienes i.e. Eicosanoids. Eicosanoids are signaling molecules derived from polyunsaturated fatty acids like arachidonic acid. They are involved in complex control over inflammation, immunity, and the central nervous system. Eicosanoids are synthesized through the enzymatic oxidation of fatty acids by cyclooxygenase and lipoxygenase enzymes. They have short half-lives and act locally through autocrine and paracrine signaling.
PGx Analysis in VarSeq: A User’s PerspectiveGolden Helix
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.
Fexofenadine is sold under the brand name Allegra.
It is a selective peripheral H1 blocker. It is classified as a second-generation antihistamine because it is less able to pass the blood–brain barrier and causes lesser sedation, as compared to first-generation antihistamines.
It is on the World Health Organization's List of Essential Medicines. Fexofenadine has been manufactured in generic form since 2011.
Storyboard on Acne-Innovative Learning-M. pharm. (2nd sem.) CosmeticsMuskanShingari
Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically manifests as pimples, blackheads, or whiteheads, often on the face, chest, shoulders, or back. Acne can range from mild to severe and may cause emotional distress and scarring in some cases.
**Causes:**
1. **Excess Oil Production:** Hormonal changes during adolescence or certain times in adulthood can increase sebum (oil) production, leading to clogged pores.
2. **Clogged Pores:** When dead skin cells and oil block hair follicles, bacteria (usually Propionibacterium acnes) can thrive, causing inflammation and acne lesions.
3. **Hormonal Factors:** Fluctuations in hormone levels, such as during puberty, menstrual cycles, pregnancy, or certain medical conditions, can contribute to acne.
4. **Genetics:** A family history of acne can increase the likelihood of developing the condition.
**Types of Acne:**
- **Whiteheads:** Closed plugged pores.
- **Blackheads:** Open plugged pores with a dark surface.
- **Papules:** Small red, tender bumps.
- **Pustules:** Pimples with pus at their tips.
- **Nodules:** Large, solid, painful lumps beneath the surface.
- **Cysts:** Painful, pus-filled lumps beneath the surface that can cause scarring.
**Treatment:**
Treatment depends on the severity and type of acne but may include:
- **Topical Treatments:** Such as benzoyl peroxide, salicylic acid, or retinoids to reduce bacteria and unclog pores.
- **Oral Medications:** Antibiotics or oral contraceptives for hormonal acne.
- **Procedures:** Such as chemical peels, extraction of comedones, or light therapy for more severe cases.
**Prevention and Management:**
- **Cleanse:** Regularly wash skin with a gentle cleanser.
- **Moisturize:** Use non-comedogenic moisturizers to keep skin hydrated without clogging pores.
- **Avoid Irritants:** Such as harsh cosmetics or excessive scrubbing.
- **Sun Protection:** Use sunscreen to prevent exacerbation of acne scars and inflammation.
Acne treatment can take time, and consistency in skincare routines and treatments is crucial. Consulting a dermatologist can help tailor a treatment plan that suits individual needs and reduces the risk of scarring or long-term skin damage.
The biomechanics of running involves the study of the mechanical principles underlying running movements. It includes the analysis of the running gait cycle, which consists of the stance phase (foot contact to push-off) and the swing phase (foot lift-off to next contact). Key aspects include kinematics (joint angles and movements, stride length and frequency) and kinetics (forces involved in running, including ground reaction and muscle forces). Understanding these factors helps in improving running performance, optimizing technique, and preventing injuries.
