The 2009 swine flu outbreak began in March 2009 when a new strain of H1N1 influenza virus was detected in Mexico, the United States, and Canada. The virus was a unique combination of gene segments from human, swine, and avian influenza viruses. Initial cases were reported in Mexico and the southwestern US, with over 1,000 suspected cases detected and 103 deaths reported in Mexico by late April. Cases were also detected in several US states and Canadian provinces. The World Health Organization declared the outbreak a public health emergency due to concerns over the virus's ability to transmit between humans and the potential for a pandemic if the virus gained mutations.
Ebola outbreak: International Health experts urge to send in military! Harm Kiezebrink
Prevention and preparation for large-scale outbreak situations are having a serious price tag, but by neglecting the outcome of risk assessments do have disastrous consequences that turn crisis situations into a worldwide disaster. Read what happens when doctors and nurses are doomed to treat highly infectious patients without any Personal Protection Equipment, no amount of vaccinations and new drugs would be able to prevent the escalating disaster.
Read about what the international president of Médecins sans Frontières (MSF) Dr Joanne Liu explains that the world is 'losing the battle' as cases and deaths continue to surge. As one of the leading health experts she urges military teams to be sent to west Africa immediately if there is to be any hope of controlling the Ebola epidemic.
During a meeting with the United Nations on Tuesday, doctors working on the frontline of the outbreaks painted a stark picture of health workers dying, explaining that patients left without care and infectious bodies lying in the streets. Although alarm bells had been ringing for six months, the response had been too little, too late.

More people died from the 1918-1920 Spanish Influenza pandemic than there were casulties as a result of the First World War. This world-wide epidemic caused by influenza viruses led to between 50 and 100 million deaths in 1918 and 1919 (as much as 1 of every 18 people).
Many researchers have suggested that the conditions of the war significantly aided the spread of the disease. And others have argued that the course of the war (and subsequent peace treaty) was influenced by the pandemic.

INTRODUCTION TO THE PAPERBACK EDITION
A half-year after the hardcover publication of Dread, sleeves across America were
being rolled up for the swine flu vaccine. New York City set out to inoculate
schoolchildren, and pregnant women lined up to get vaccinated at their
obstetricians’ offices. Although the swine flu outbreak had caused less harm in the
six months since it started than almost any flu event of the past century, everyone
was alarmed. And everyone had questions.
At a symposium in Holland, people asked me whether I thought their
government really needed to buy up enough flu vaccine for every Dutch citizen. A
reporter in Chicago told me he saw boycotts of soccer games involving Mexican
teams, because people thought the flu could be spread by Mexicans. A Canadian
radio host asked whether her country was worrying too much about the flu. An
Australian physician and another in France chided me for my refusal to endorse the
sky-is-falling rhetoric of flu preparedness. Around the U.S., hand-sanitizer
dispensers flowered at supermarket checkouts, airport security points, libraries, and
classrooms; colleagues and friends wondered whether the sanitizing gel could
really stop the flu virus. At home in New York, nurses cried foul at mandatory
immunizations (later rescinded). Physicians expressed frustration at the difficulty
of persuading parents to have t ...
U.S. Preps For Ebola Outbreak Cases May Exceed 100,000 By December “The Numbe...Hope Small
The article does not mention that a completely unrelated strain of ebola has broken out in the Congo. What are the chances of that?
Though news on the Ebola virus has been muted since two American health care workers were admitted to U.S.-based facilities last month, the deadly contagion continues to spread. According to the World Health Organization more than 40% of all Ebola cases thus far have occurred in just the last three months, suggesting that the virus is continuing to build steam.
Physicist Alessandro Vespignani of Northeastern University in Boston is one of several researchers trying to figure out how far Ebola may spread and how many people around the world could be affected. Based on his findings, there will be 10,000 cases by September of this year and it only gets worse from there.

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
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
