Down's Syndrome, also known as trisomy 21, is a genetic condition where a person has 47 chromosomes instead of the usual 46, causing mental retardation and other problems ranging from mild to serious. Common physical signs include a flattened nose, small ears and mouth, upward slanting eyes, and short hands and fingers. Risk factors include increased maternal age and parents being carriers of the translocation. While there is no cure, early intervention and treatment of complications like heart defects can help development.

Down syndrome (DS or DNS), also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is typically associated with physical growth delays, characteristic facial features and mild to moderate intellectual disability. The average IQ of a young adult with Down syndrome is 50, equivalent to the mental ability of an 8- or 9-year-old child, but this can vary widely.

Down Syndrome is a combination of physical abnormalities and intellectual disability characterized by a genetic defect in chromosomes. It is the commonest identifiable cause of intellectual disability, accounting for almost one third of cases. It occurs equally in all races with an overall incidence rate of approximately 1 in 800 births.
Down syndrome - A Parent's perspectivelauintransit
This PowerPoint was created for a presentation provided to health professionals at my local hospital. I would be happy to present this PowerPoint to any hospital in Queensland, or alternatively, I give permission for this PowerPoint to be used by others for future presentations for health professionals. It was designed to be delivered by parents of a child with Down syndrome. Please feel free to provide constructive feedback on the presentation.
Down syndrome is one of the known genetic disorders, in which an individual has an extra full or partial copy of chromosome 21.
Human beings have 23 pairs of chromosomes combinely received from biological father and mother.
This abnormal cell division, down syndrome, causes many issues relating to the intellectual ability, physical features, learning ability and developmental delays in an affected child.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Down's Syndrome
1.
2. About Down’s Syndrome
Also known as trisomy 21
A genetic condition in which a person has 47
chromosomes instead of the usual 46
Causes mental retardation and other problems
Ranges in severity, so developmental problems
may range from mild to serious.
serious.
3. Causes
No exact cause of ADHD
Most children with ADHD also have at least one
other developmental or behavioral problem.
Depression, lack of sleep, learning disabilities, tic
disorders, and behavior problems may be confused
with, or appear with, ADHD
Imaging studies suggest that the brains of children
with ADHD are different from those of other
children.
4. Physical Signs
Flattened nose
Small ears
Small mouth
Upward slanting eyes
Wide, short hands with short fingers
Separated joints between the bones of skull
Decreased muscle tone at birth
Protruding tongue
Small head
5. Risk Factors
A woman’s chance of giving birth to a child
with Down syndrome increases with age.
Women who already have a child with Down’s
syndrome typically have a 1 % chance of having
another child with Down syndrome.
Parents who are carriers of the translocation
for Down syndrome can pass the genetic
translocation onto their children.
7. Treatment
No Cure
No way to prevent or change the risks of
having a child affected with Down syndrome
At a early age, when they are babies or
toddlers you can take them to a special school
so they can get use to what it will be like when
they grow up
